Description

The present invention relates to the field of mechanization of track facilities of railway transport and can be used both for overhaul of the track and its current maintenance.

Known devices for processing an intermediate rail fastening of a railway track, containing a trolley moving along the track rails with probing organs and working mechanisms, for example, by author. St. USSR No. 958569, E 01 B 29/28; author St. USSR No. 1059044, E 01 B 29/28; or containing a crew moving along rails with a trolley moving along it with probing organs and working mechanisms, for example, by author. St. USSR No. 304326, E 01 B 29/28; US Pat. USSR No. 656539, E 01 B 29/28; author St. USSR No. 787541, E 01 B 29/28; author St. USSR No. 1204658, E 01 B 29/28. In known devices, the movement of working mechanisms sequentially from sleepers to sleepers is carried out with a stop over the sleepers to process its rail fasteners and the cycle of processing sleepers fasteners, thus, includes the time spent on moving work mechanisms and processing fasteners, which determines the speed of the devices, which, in turn, determines their performance. Productivity is enhanced by simply increasing the trolleys.

A device according to US Pat. RF №2154710, Е 01 В 29/28 (adopted as a prototype), containing a frame with wheels running along the track rails, two carts moving along the frame with power cylinders with probing bodies, fasteners, rail clamps and working mechanisms. During the processing of the fastenings of the sleepers of one of the carts, the second cart moves to the next sleeper to be processed, which provides a continuous process for processing fasteners while continuously moving the device along the path to be processed, which, in turn, ensures high productivity and efficiency of the device.

However, in the known device, as in the above known devices, the working mechanisms are intended for processing fasteners such as KB, RCB and the like, containing a voltage regulator with a vertical axis of its placement (bolt with nut, screw, to tighten the terminal to the rail sole) ), and cannot be used for processing anchor fasteners of the type ARS containing a six-sided voltage regulator with a horizontal axis of its placement along the rail (Track and track facilities. - 2002. - No. 5. - p.2-5; application of the Russian Federation 2003118554/11, E 01 B 1/00 -. Bul (BIPM) -.. 2004. - №35).

A high-performance and effective device for processing an intermediate anchor rail fastening of the ARS type is required, which is able to regulate the force of pressing the elastic terminal to the sole of the rail by successively turning the hexagonal voltage regulator with the axis of its horizontal position along the rail to the next face, as well as removing it from the fastening anchors.

To this end, in a known device comprising a frame with wheels running along rails of the track, two carts movable along the frame with power cylinders with probing bodies, fasteners, rail clamps and working mechanisms, working mechanisms are placed on the rail clamps of each truck and each working mechanism is driven by swinging movement of the power cylinder by a lever, one end of which is equipped with a hinge, and the second driven along it (the lever) by the power cylinder with an open-ended wrench for I interaction with hexagonal bonding voltage regulator, wherein the hinge arm is situated on the carriage to enable its movement along a circular arc concentric to the axis of the voltage regulator.

The rail clamps equipped with jaws pressing on the lateral faces of the rail head are equipped with hooks for the rail head.

In addition, the sponges of the wrench are hinged and equipped with a collet clamp.

The presence in the device of two wheels of trolleys movable relative to the frame with running along the rails of the track with working mechanisms and rail clamps on them allows the device to continuously move along the track with alternating stepwise movement of the trolleys with a productive and efficient continuous process for processing fasteners.

The presence on each trolley of probes located at the location of the organs with the placement of the working mechanisms on their rail clamps allows you to stop the trolley over the workpiece with the orientation and fixation of the working mechanisms relative to the rail fasteners.

The equipment of one end of the working mechanism lever driven by the swinging motion with a hinge on the carriage moving along the concentric axis of the bond tension regulator and the second driven by an open-ended wrench allows you to put the key on the hex voltage regulator and turn it to the next face when moving the lever hinge along an arc of a circle or press the voltage regulator until its pins are pulled out of the anchor sockets and push the regulator out when turning the lever around the hinge against opposite direction.

The supply of rail clamps together with the jaws of the rail head pressing on the lateral edges of the rail head along with the stop of the carriage and the orientation of its working mechanisms relative to the rail fasteners makes it possible to compensate when the voltage regulator is rotated or removed, the resulting vertical reactive force reaching a value exceeding 20 kN .

The implementation of the spanner spanners articulated with their collet clamp allows you to easily put the key on the voltage regulator, followed by fixing the key on the regulator.

Figure 1 schematically shows the proposed device in positions A and B, side view; figure 2 is an end view of the trolley; figure 3 is a view of the working mechanism; figure 4 - wrench with a collet clamp.

On a frame 3 equipped for moving on rails 1 of a track 3, mounted are movable along it with power cylinders 4, two trolleys 6 and 7 on rollers 5. Each trolley is equipped with bodies 8 probing the location of fastenings and two rail clamps 9.

Each rail clip 9 is a lever pair pivotally mounted on a trolley connected to each other by a power cylinder 10. To interact with the rail head 1, the sidewalls 11 of the lever pair are equipped with jaws 12 and hooks 13 under the rail head for pressing on the side faces of the rail head.

A working mechanism 14 is mounted on each sidewall 11 of the rail clip 9, which is a lever 16 with a hinge 17 with a hinge 17 at its upper end driven by a rocking motion by a power cylinder 15. The hinge 17 is placed on the carriage 18, equipped with rollers 19 for moving the carriage, and therefore the hinge along the radial groove 20, the axis of symmetry 21 of which is part of a circle concentric with the axis of the voltage regulator 22 of the APC rail rail fastening. The lower end of the lever 15 is equipped with a wrench 23 with an open pharynx, translationally moving along the lever 16 by a power cylinder 24.

To fix the carriage 18 in the groove 20, and consequently, to fix the hinge 17, a stop 26 driven by the power cylinder 25 is mounted.

Figure 4 shows a wrench, the jaws 27 of which are hinged, springable 28 and reduced by a collet clamp 29, driven by a power cylinder 30.

The device operates as follows.

During the fastening of the fasteners by the working mechanisms of one of the trolleys, the second moves over and is configured to process the fastenings of its next sleepers. Moving each trolley through a tie for processing all sleepers with both trolleys in their general arrow direction along the path, for example, when processing sleepers a, a1, a2, a3, etc. trolley 7, and sleepers b, b1, b2, b3, etc. trolley 6. Each trolley is moved when the power cylinders 4 of both trolleys are turned on. Each trolley is stopped when it detects fastenings of its next sleepers with its probing organs.

In position A, the situation is depicted where, on the trolley 6 braked by rail clamps, the processing of fasteners of the sleepers b1 ends, and the trolley 7 has arrived and tuned in to handle the fastenings of its next sleepers a2. The trolley 7 is braked by its rail clamps and the fastening of the fastenings of its next sleepers a2 starts, and the trolley 6 is released and moves to its next sleepers b2, while the device 3 moves along the arrow and position B. Then the trolley 6 is braked to handle fastenings of the sleepers b2, and the trolley 7 disengages and moves to its next a3 sleeper, while the device frame 3 moves along the arrow as well - the subsequent situation of position A.

The truck is braked by its rail clamps 9 when their sides 11 are brought together by a power cylinder 10 until the pressure jaws 12 abut against the side faces of the rail head with the hooks 13 entering under the rail head, than each operating mechanism 14 is oriented relative to the fastening voltage regulator 22 and fixed in this position. The power cylinder 24 and the wrench 23 are turned on, moving along the lever 16, is put on the hexagonal fastener voltage regulator 22. The implementation of the key with hinged jaws 27, reducible collet clamp 29, simplifies the process of putting the key on the voltage regulator. By turning on the power cylinder 25, the stop 26 is removed and by turning on the power cylinder 15 the lever 16 of the working mechanism is shifted to the rail, moving its hinge 17 along the eccentric axis of the voltage regulator 22 to the circular arc and thereby turning the voltage regulator to its next eccentric axis to increase the pressing force of the spring terminal fastenings to the rail. The key is removed when the power cylinder 24 is reversed and when the power cylinder 15 is reversed, the operating mechanism lever 16 is returned to its original position. If necessary, repeat the operation. The inclusion of the power cylinder 25 focus 26 carriage 18 is locked in its original position.

When removing the voltage regulator when putting the key on it, the force of the power cylinder 24 is increased until the axes of the voltage regulator leave the anchor hooks, and by turning on the power cylinder 15 in the opposite direction that was previously turned on, turn the lever 16 around the hinge 17 fixed in place from the rail, thereby pushing voltage regulator from the anchor.

The force of pressing the voltage regulator can reach a value exceeding 20 kN, and the torque for turning the voltage regulator of a magnitude exceeding 500 Nm, and the reactive forces arising from this, including lifting the trolley, are compensated by its rail clamps, including capture of a rail under his head.
