Description

The invention relates to devices for fastening cars and other wheeled vehicles to the floor of vehicles, in particular specialized railway cars for transporting cars.

It is known that the device used for fastening cars in railway cars for transporting cars, including a wheel support having the ability to rotate and fix in the working position by means of a locking mechanism, as well as a device for fixing the stop to the floor of the car (see, for example, stop .835.50.00.030СБ wagon for cars model 11-835 TU24.05.822-84 manufactured by Rautaruukki, Finland).

The disadvantage of this device is the high complexity of its installation, associated with the need to use a special key, as well as additional fixing (unlocking) it to the floor of the car using a special manual latch in both the working and non-working positions. In addition, the lack of reliability of vehicle retention during collisions, for example, during the formation of the composition, due to the dependence of the working height of the stop on the clearance of fixed cars, which makes unreliable fastening of cars with low clearance.

The known device does not have a rigid fixation to the floor in the transverse direction relative to the longitudinal axis of the car, which in collisions, especially on curved sections of the track, can lead to lateral displacement of cars and to their complete unfastening.

The known device is inconvenient in operation, because the emphasis is transferred from the working position to the non-working position and vice versa by the operator manually in an inclined position. In addition, it is necessary to constantly monitor the presence of through passage necessary for loading cars, and the safety of the stops themselves.

To install devices on the car, a special reinforced floor is provided, made of corrugated metal rolling having on the corrugation tops (located across the car) two rows of slotted rectangular grooves symmetrically located relative to the longitudinal axis of the car, designed to install and engage the stop base in the working position, as well as along one row of grooves at the edges for installing the stops in the idle position. During operation, the grooves on the corrugations are deformed and require constant monitoring of their condition and maintenance. Also, dust is additionally sucked in through the grooves inside the carriage when driving, and from the floors of the upper tier, it is possible for the cars installed at the bottom to leak products from cars on the upper tier. Since when installing the stop, three corrugations lying in the same plane are simultaneously involved, there are at least four zones in the places of floor bending (in cars with a lowered base part of the floor), in which the stops are not installed, which can lead to a reduction in the number of vehicles transported in the carriage. In addition, due to the limited length of the grooves and the symmetrical design of the support providing two-sided girth of the wheel, it is not possible to install the stop on the side of the car in the existing radial clearance between the wheel and the outer contour of the wheel body niche at a height greater than the clearance of the car itself, which does not allow heavy vehicles to be transported low clearance, requiring each wheel to be fixed on both sides, i.e. two stops.

The presence of corrugations also reduces the useful height of the cargo space by the amount of their protrusion above the base of the floor.

The invention solves the problem of increasing the reliability of the device for mounting cars to the floor while reducing the complexity of the mounting process, simplifying the design of the floor, as well as expanding the range of transported wheeled vehicles.

To solve this problem, in the known device for attaching a car to the vehicle floor, including a wheel stop, having the ability to rotate and fix in the working position using the locking mechanism, as well as a device for fixing the stop to the floor, the wheel stop is made in the form of a horizontal L-shaped bracket , in the working position, having the ability to abut against the outer corner of the wheel, for which the bracket using a vertical strut is fixedly mounted on a base mounted on a horizontal rod with fixation about t of rotation in the transverse vertical plane and with the possibility of movement along the rod, which, in turn, is movably mounted with the possibility of fixation in the working position at an angle to the axis of the wheel on the outer and inner rails, rigidly attached to the floor parallel to the longitudinal axis of the vehicle and provided with a top horizontal shelves directed into the carriage, while the angle of the long part of the L-shaped bracket on the base is approximately equal to the angle of the rod relative to the axis of the track CA in the working position, fastening the outer end of the rod to the outer rail is made integral with the mechanism for fixing the working position of the rod, for which the rod is equipped with a vertical sleeve fixed to the end and rotatable, provided with a C-hook on the bottom on one side, covering the end of the horizontal guide rail and having a friction notch on the contact surface, and on the other hand, a horizontal locking shaft mounted using a threaded connection in the through hole of the sleeve with possible the abutment against the vertical part of the guide and the pedal provided on the opposite side, and the fastening of the inner end of the rod to the inner guide is a rotatable vertical sleeve with a similar C-shaped hook from below, covering the end of the horizontal shelf of the guide and having a friction notch on the contact surface .

To fix the base from turning relative to the rod, the section of the rod is made rectangular, and the base is made in the form of a rectangular clamp having a fixed footrest for moving the rod relative to the guides, and a L-shaped bracket relative to the rod.

The clamp is equipped with at least one rolling element in the form of a ball, for which it has a corresponding socket in contact with the upper surface of the rod.

The outer end of the rod is provided with at least one rolling element in the form of a ball, for which the vertical sleeve at the point of contact with the rail is equipped with a corresponding socket.

The rod has the ability to turn in the horizontal plane relative to the sleeve of the outer end and to be inoperative along the outer guide, as well as fix in this position while maintaining horizontalness, for which the inner end of the rod is equipped with a double fixed support and hook fixed to the bottom with lateral hooks perpendicular to the rod while the base of the hook has the ability to lean on the floor of the vehicle, and one of the hooks in the inoperative position - interaction from the outside with the vertical the flaxen part of the guide.

To ensure the orientation of the working surface of the C-shaped hook of the sleeve of the inner end of the rod relative to the horizontal shelf of the rail when the rod is moved from the idle position to the working sleeve, it is equipped with a rotation limiter made in the form of a rectangular plate rigidly fixed parallel to the working surface of the hook of the hook located inside the rod with the possibility of contact with it horizontal surfaces and abutting one of the vertical edges in the corresponding vertical surface of the rod in position about espechivayuschem contact the working surface of C-shaped hook guide with a horizontal shelf, which between the vertical edges and surfaces of the rod in the inoperative position have clearances corresponding value.

The technical advantage of the device is to increase the reliability of car fastening (due to the emphasis in the form of a horizontal L-shaped bracket covering the outer corner of the wheel and securely fixed in the working position, located at an angle to the axis of the wheel of the rod, which in turn is fixed on the outer guide using the fixing shaft) while reducing the complexity of the process of fastening the wheel (since the movement of the L-shaped bracket to the stop in the wheel is carried out using the foot of the clamp, and fixing the bracket in Este with the rod in the operating position by means of locking the pedal shaft, wherein movement of the collar along the rod, and the rod end of the outer guide is facilitated by the presence of balls between the contact surfaces).

Due to the design features of the claimed device, the need to control the possibility of through passage of cars, the safety of the stops, simplifies the design of the floor while reducing its weight, and also expands the range of transported wheeled vehicles.

The invention is illustrated by drawings, where in Fig.1 is a General view of the device in the operating position (top view); figure 2 is the same as in figure 1 (front view); figure 3 is a section aa in figure 1 (view of the mounting of a vertical shaft at the inner end of the rod; support with a stand, clamp and footboard are not conventionally shown); figure 4 is a General view of the emphasis in the idle position (front view); figure 5 is a section bB in figure 2; figure 6 - installation of brackets of the right and left execution on one wheel (side view).

The inventive device has (Fig. 1) a wheel stop made in the form of a horizontal L-shaped bracket 1 having a long part for abutment against the wheel end (rolling surface) and a short part for abutment on the outer side part of the wheel in the working position of the abutment. The bracket 1 is rigidly attached to the upper end of the rack 2 (figure 2), the lower end of which is rigidly fixed to the base, in particular on the clamp 3, which covers the rod 4 (figure 1), made to fix the clamp from turning in the form of a rectangular pipe. The clamp is also made rectangular and has the ability to move along the bar.

To facilitate the movement of the bracket 1 along the rod, the clamp 3 on the inner side above the rod has a socket in which the ball 5 is located.

The step 6 is fixedly fixed on the upper surface of the clamp 6. The clamp can also be made in the form, for example, of a carriage with a C-shaped base or two L-shaped grips covering the bar, etc., and the bar itself, for example, from an I-channel channel, etc.

The rod 4 is placed with the possibility of movement on the outer 7 (figure 3) and inner 8 guides, rigidly attached to the floor parallel to the longitudinal axis of the vehicle and equipped with horizontal shelves directed inward from the top of the vehicle.

In the working position, the bracket 1 has the ability to abut against the outer corner of the wheel of the vehicle located along the vehicle (the long part of the bracket abuts against the rolling surface, and the short part rests on the outer side of the wheel). In this case, the rod 4 in the working position has the ability to be located at an acute angle to the axis of the wheel (the outer end of the rod is closer to the axis of the wheel than the inner one). To create the possibility of abutment in the wheel, the bracket 1 is thus fixed on the clamp 3, so that the angle of its long part is approximately equal to the angle of the rod relative to the axis of the wheel.

The rod 4 at the outer end has a vertical hole in which the sleeve 9 (FIG. 3) is rotatably placed at its upper end. The sleeve in the lower part is equipped on one side with a C-shaped hook having a friction notch, and on the other hand, with a horizontal locking shaft 10 mounted with a threaded connection in the through hole of the sleeve and provided with the pedal 11 from the outside. The lower end of the sleeve 9 is mounted on horizontal shelf of the outer guide 7 so that the C-shaped hook with its surface with a friction notch rests on its end. In the working position, the shaft end abuts against the vertical part of the guide 7, while ensuring that the C-shaped hook is pressed against the guide shelf and, accordingly, the rod 4 is fixed on the outer guide. At the lower end of the sleeve 9 there is a socket in which the ball 12 is placed, resting on a horizontal guide 7 and facilitating the movement of the rod 4 along it.

At the other end of the rod 4 there is also a similar hole in which a sleeve 13 is placed at its upper end with a similar C-shaped friction hook from below, covering the end of the horizontal shelf of the guide 8.

The rod 4 has the ability to turn in a horizontal plane relative to the outer sleeve 9, the location in the idle position along the outer guide 7 and fixation in this position while maintaining the horizontal. To do this, the inner end of the rod is equipped with a double controversial locking hook 14 (Fig. 4), rigidly fixed from below with lateral hooks perpendicular to the rod, while the base of the hook can be supported on the vehicle floor, and one of the hooks in the idle position of the rod can interact outside with the vertical part of the guide 7.

To ensure the orientation of the working surface of the C-shaped hook of the sleeve 13 on the rod 4 when transferring the latter from the inoperative position to the working sleeve is equipped with a rotation limiter 15 (Fig. 3 and Fig. 5), made in the form of a rectangular plate rigidly fixed parallel to the working surface of the hook of a rectangular plate located inside the rod with the possibility of contact with its horizontal surfaces and abutment of one of the vertical edges in the corresponding vertical surface of the rod in a position providing contact of the working surface C- shaped hook with a horizontal shelf guide, for which between the vertical edges and surfaces in the inoperative position there are gaps of the corresponding size.

The device can be made in right-handed and left-handed versions (Fig.6), characterized by a mirror arrangement of the L-shaped bracket 1 with a clamp 3 and a step 6 on the rod 4 relative to the axis of the fixed wheel.

The inventive device operates as follows.

In the operating position of the device, the rod 4 is fixedly fixed at one end on the guide 7 by the shaft 10, the rotation of which ensures that the working surface of the C-shaped hook of the shaft 9 is pressed against the horizontal shelf of the guide 7, and the other end on the guide 8 due to the fit of the working surface of the C-shaped hook shaft 13 to its horizontal shelf. In this case, the L-shaped bracket 1 abuts against the rolling surface and the outer side of the wheel. Moreover, when the wheel acts on the bracket 1 due to the angular location of the rod, the clamp 3 does not have the ability to move along the rod 4 out of the wheel, since there is a lateral force pressing the bracket 1 to the outer side of the wheel, and the presence of the friction notch increases the reliability of the rod engagement with guides.

To put the device into an inoperative position, the operator turns the shaft 10 with the pedal 11 until the pedal rests on the floor of the car, which ensures that the shaft comes out of contact with the side of the guide 7. In this case, the C-shaped gear of the shaft 9 disengages from the guide 7, and the outer end of the rod 6 gets the ability to move along it. Next, using the step 5, the operator extends the bracket 1 from the gap between the wheel and the body to the outer end of the rod 4, rotates the rod until the shaft 13 disengages from the guide 8, and, throwing the inner end of the rod through the guide 8 (due to vertical movement around the ball on the shaft 9), rotates it until the hook 14 engages with the outer guide 7. During rotation, the released inner end of the rod rests on the lower part of the hook 14 (Fig. 4), holding the rod in a horizontal position and eliminating jamming the outer end of the rod 4 on the shaft 9. In this case, the latch 15 on the rod (Fig. 3 and Fig. 5), while turning the rod into the working position, orients the shaft 13 with its C-shaped hook onto the horizontal shelf of the guide 8, preventing the possibility of spontaneous rotation of the shaft in a non-working position.

The device is transferred from a non-working position to a working one by the operator in the reverse order.

To fix the car, four brackets are used on the rods - two left-handed and two right-handed. In this case, the brackets are installed from the external ends of the car or in the base (under the bottom) space.

To fix heavy vehicles, including those with reduced clearance (Fig. 6), each wheel is fixed on both sides with a right-handed and left-handed bracket, respectively.
