Description

The invention relates to the field of mechanization of operations in the track economy of railways and can be used when changing inventory rails with long lashes with fastenings such as railways.

Various wrenches are known for use when tightening nuts on intermediate rail fasteners. These include, for example: “Machine for loosening and tightening the nuts of rail fastening of the railway track”, autosvid. USSR No. 787541, ЕВВ 29/28; "Device for screwing and unscrewing the elements of the intermediate fastening of the rail link", autosvid. USSR No. 958569, ЕВВ 29/28; “Device for unscrewing the nuts of embedded bolts of the rail-sleeper lattice”, ed. USSR No. 1081256, ЕВВ 29/28; "A device for loosening the nuts of terminal bolts when assembling the links of the railway track", ed. USSR No. 1416590, ЕВВ 29/28; "Device for screwing and unscrewing nuts for intermediate rail fastening of the railway track", RF patent No. 2154710, ЕВВ 29/28. All these wrenches, which have various additional features, have one drawback - they cannot be used to unscrew the nut or screw and, having created the necessary clearance, lift and slide the raised terminal of the RCB and screw the nut or screw again with the required pressing force.

It is known "Device for screwing and unscrewing the elements of the intermediate fastening of the rail link", autosvid. USSR No. 1046378, ЕВВ 29/28 - taken as a prototype. It consists of a wheeled crew moving along rails from the railroad ties to the railroad ties, on the frame of which wrenches are mounted in pairs above each rail, the spindles of which are interconnected by a traverse moving in the vertical plane from the power cylinder, which interacts by means of compensating springs with the wrench heads. On the frame are also placed probing the location of nuts or screws organs.

The disadvantage of this device when working with rail fastening type RCB is that with this device it is impossible to perform the entire set of required operations for fastening long lashes with fastenings of type RCB when replacing inventory rails.

Such a mobile device is necessary that would allow, after stopping the device at the next sleepers, to sequentially unscrew the nut or screw, releasing the spring terminal installed in the mounting position, lifting the spring terminal above the protrusion of the stop bracket, shifting the terminal to the working position and screwing the nut or screw with required torque.

To achieve this goal, in a mobile device for fastening long lashes with fastenings of the type of reinforced concrete, when replacing inventory rails, consisting of a wheel crew moving along rails, on the frame of which wrenches are mounted in pairs above each rail, the spindles of which are interconnected by a traverse movable in a vertical plane from the power cylinder interacting by means of compensation springs with a cross member connected to the heads of the socket wrenches on the traverse on the outside of each spindle an additional power cylinder and a clamping mechanism with shaped gripping jaws for lifting the spring fastening terminal and a pusher for pushing the specified terminal are installed, and the pusher is made in the form of a two-armed lever, on the upper arm of which there is a curved groove for accommodating a slider associated with it the stock of the above additional power cylinder.

The device is supplied with an additional power cylinder mounted on the traverse on the outside of each spindle and a tick-borne mechanism connected to the specified cylinder with shaped gripping jaws for lifting the spring fastening terminal and a pusher for pushing the specified terminal made in the form of a two-shouldered lever, on the upper arm of which there is a curved groove for placing in it a slider associated with the rod of the above-mentioned additional power cylinder allows, after stopping the device at the next sleepers , To produce successively unscrewing nut or screw, releasing the set assembly position the spring clip, raised above the projection of the spring terminals abutment bracket Sdvizhkov terminals in the working position and screwing a nut or a screw with the required torque.

The proposed mobile device for securing long lashes with fastenings of the type RZB when replacing inventory rails is illustrated by the drawings shown in figures 1-8.

Figure 1 shows the mounting position of a fastening of a type of reinforced concrete, which is a spring terminal 2 shifted from the rail 1 so that it in its front part abuts against the protrusion of the thrust bracket 3 and is pressed against the shift by a screw 4 (or a nut of a bolt with a different design bonding). Figure 2 shows the operating position of the spring terminal 2, pressing the rail 1 with the required force by screwing the screw 4 (or the nuts of the embedded bolt with a different fastening design).

The mobile device contains a wheeled crew 5 (Fig 3), on the frame of which are mounted in pairs wrenches 6 (Fig 4). Each wrench 6 is a geared motor 7 with a spline spindle 8, along which the wrench head 9 can move. The movement is carried out using a power cylinder 10, the rod of which is mounted on a traverse 11, against which the compensation springs 12 abut, interacting with the jumpers 13 at the second end fastened to the heads of the keys 9. On both sides of the crosshead 11, on the outside of each spindle 8, brackets 14 are placed, on each of which a power cylinder 15 is mounted, the rod of which interacts with the upper rods tong mechanism 16, also disposed on the bracket 14. At the bottom of the tong mechanism 16 are shaped gripping surfaces 17 arranged on the remote console 18. Ibid console 18 is limit stop 19 (Figures 5, 6). A remote finger with a slider 20, which is placed in the figured groove 21 of the pusher 22 with the possibility of movement in it, is fixed on the rod of the power cylinder 15. The pusher 22 is mounted on the bracket 14 with the possibility of rotation on the axis 23, forming a two-arm lever (Fig.7, 8). On the frame of the wheeled carriage 5 there is an organ probing location of 4 screws, for example, in the form of a laser beam.

A mobile device operates as follows. Before changing the inventory rails 1 on a whip of a welded jointless path, the screws 4 (or nuts of the embedded bolts) are unscrewed by an amount that allows you to raise the spring terminal 2 above the protrusion of the stop bracket 3 and move it to the mounting position (Fig. 1). Then, the spring terminal 2 is fixed in this position using the same screw 4 (or nut). After replacing the inventory rails with long lashes of a welded path, the proposed mobile device begins to move on it. When fixing the screw 4 with a probing organ, for example, with a laser beam, the crew 5 stops at the next sleepers and the power cylinder 10 of the axial movement of the key heads 9 is turned on. The power cylinder 10 acts on the yoke 11 and through the compensation springs 12 on the jumpers 13 fastened with the keys 9. After putting the key 9 on the head of the screw 4, the gear motor 7 is turned on and through the spline 8 the key 9 unscrews the screw 4 by 1.5-2 turns, making room for the spring terminal 2 to be lifted above the protrusion of the stop bracket 3. Lifting the keys 9 when unscrewing screws 4 occurs due to the compression of the compensation springs 12. After this, each power cylinder 15 is mounted on the bracket 14, the rod of which, rising and acting through the lever system of the clamp mechanism 16, reduces the shaped jaws 17 and, thereby, using the lift on the surface of the jaws 17, raises to a predetermined height (above the protrusion of the thrust bracket 3) the front surface of the terminal 2 (Fig.1, 5). In the final part of the lifting of the rod of the actuating cylinder 15, the extension finger fixed on it with the slider 20, placed in the figured groove 21 of the pusher 22, falls on the curly part of the groove 21 and turns the pusher 22 on the axis 23. The lower arm of the pusher 22 biases the spring terminal 2 for the protrusion of the stubborn bracket 3 (figure 2, 8). In order to prevent excessive displacement of the terminal 2, for example, from the impact of the pusher 22, a limit stop 19 is located on the console 18 located at the bottom of the tick mechanism 16. The upper plate on the stop 19 prevents the spring terminal 2 from jumping during the closing of the shaped jaws 17 After setting the spring terminal 2 into working position, the cylinder rod 15 is lowered, spreading the shaped jaws 17 of the tongs mechanism 16. The nutrunners 6 are turned on, and the screws 4 are screwed with the required torque. At the end of the screwing, the power cylinder 10 is triggered to lift, and the device moves to the next sleeper.
