Description

The invention relates to railway track repair devices, in particular to sleepers replacement devices,

A device for replacing railroad sleepers is known, comprising a frame, a sleeper grab attached to the frame by means of a bar system mounted on a frame controlled by hydraulic cylinders. The sleeper gripper performs its working action by pre-gripping the sleeper by its end. The sleepers are carried out horizontally from the railway track.

A disadvantage of the known device is the inability to replace the sleepers in cramped conditions, since the sleepers are replaced by lateral lateral removal horizontally. Such carrying out is impossible on medium paths and in cramped conditions. The installation on the frame of the core system allows the sleeper to be captured only at its end.

A device for replacing railroad sleepers is known, comprising a sleeve sewn on a vehicle frame, a horizontal guide mounted on the frame by means of a hinge that can be rotated by a drive across the device in a clockwise direction, and a sleeper gripper mounted on said guide rail. with the ability to move along;

In the known device, the axis of rotation of the guide is offset relative to the rail of the railway track, around which the sleeper rotates when it is pulled out. This causes an increase in efforts on the rail and the sleeper when it is rotated due to abutment of the tie in the ballast, which leads to an increase in the power consumption of the device. In addition, the device does not provide the pulling of the sleepers on both sides of the path, which reduces the convenience of its work. This reduces the effectiveness of the device.

The purpose of the invention is to increase the efficiency of the device by providing ease of operation and reducing energy consumption.

To achieve this goal, in a device for replacing railroad sleepers containing a frame mounted on the vehicle, a horizontal guide mounted on the frame by means of a hinge can be rotated by a drive across the device in a clockwise direction, and a sleeper gripper mounted on said guide rotatably driven along it, the horizontal guide is mounted on the frame by means of an additional hinge that can be rotated clockwise to the indicated lead One turn, the hinge and the additional hinge are made detachable and arranged in vertical planes corresponding to the placement of the track rails.

In addition, cuts are made on the horizontal guide

0 to the rails forming the specified hinges with the HP. MI; the sleeper gripper is mounted on a horizontal rail with the help of a hinge, the axis of rotation of which is parallel to the longitudinal axis of the device;

In order to expand technological capabilities, the sleeper grab is formed by the grapple jaws, on the outer lateral sides and in the lower inner parts of which there are scrappers for the scoop of ballast.

FIG. 1 shows a device for replacing railroad sleepers, front view; in fig. 2 is the same embodiment of the device; in fig. 3 - the same, another

5 shows an embodiment of the device in FIG. 4 — sleeper gripper; in fig. 5 - the same, top view.

The device for replacing railroad sleepers contains mounted

0 on the vehicle frame 1, moving along the rail.am 2 ways.

The gripper 3 for the sleeper 4 is made in the form of the jaws 5 of the grapple connected by a rotary hinge 6. The gripper 3 is mounted

5 on the horizontal guide 7 and connected to it by means of a displacement drive along the guide 7, which is a hydraulic cylinder 8. The guide 7 is connected to the frame 1 through 0 by means of hinges 9 and a turning actuator relative to these hinges 9, made, for example, in the form of a hydraulic cylinder 10. The hinges 9 are detachable and located on both sides of the longitudinal axis.

5 devices in vertical planes aligned with vertical planes passing through the axes of symmetry of the track rails. When the device is operated with a guide, only one of the hinges 9 is connected,

This enables rotation of the guide 7 across the device clockwise or against it by the hydraulic cylinder 10. The axis of rotation of the hinge 9 is formed by the axis of the rail head (Fig. 2). This is done in order

5 so that the sleeper 4 is rotated by the hydraulic cylinder 10 around the rail 2 (movement V2 of FIG. 1). During this rotation, sleepers 4 sleepers do not abut against the ballast in the left part relative to the axis of rotation, which reduces the energy and energy required for rotation.

The spike of the hinge 9 may be the rail head 2 (FIG. 3), which is more technological than the design of the hinge 9 of FIG. 2. But this may cause twisting load on the rail 2 when turning the sleepers from friction. Therefore, the device of FIG. 3 can be used with a small number of replaceable sleepers per unit length. The gripper 3 can be connected to the guide 7 by means of a hinge 11, the axis of rotation of which is parallel to the longitudinal axis of the path (Fig. 4). energy costs. For fixing from the spontaneous rotation of the grip 3 relative to the hinge 11, the grip 3 can be connected to the guide 7 additionally by an articulated quick-pull link 12 or a hydraulic cylinder. device connected to the frame 1. In this case, the frame 1 should have rail clamps 14. On the jaw x 5 can be installed scrapers 15c cutting elements 16 located on the outer outer sides of the jaws 5, and cutting elements 17 located on the lower edges of the jaws 5 and attached to them. This makes it possible to remove the ballast in front of and under the ends of the sleepers 4, the work of gripping 3 as a grapple or making translational motion by scrapers 15, both when removing the sleepers and preparing the bed for a new sleeper.

The device for the replacement of railway sleepers works as follows.

Using the scrapers 15, the gripper 3 produces translational motion along the sleeper 4 by changing the length of the hydraulic cylinder 8 to cut the ballast stuck to the sleeper 4. After that, the grip 3, the work of the grab and scrapers 15, removes the ballast before the ends of the sleepers. Then, by gripping the sleeper 4 in the middle, by gripping 3, it is displaced in the direction of carrying out the sleepers, and the ballast is removed from the empty bed under the end of the sleepers, then the tie is displaced in the direction opposite to the removal of the sleepers (to the right) - Vi movement by the hydraulic cylinder 8 along the guide 7 until the sleeper leaves the rail from the side of the sleeper removal (left rail in FIG. 1). After that, the hydraulic cylinder 10 rotates the sleepers 4 relative to the hinge 9. At the same time, the guide 7

and grip 3 with respect to this hinge is V2 motion. This movement is carried out until the bottom edge of the lifted end of the sleeper 4 is higher than the rail heads. After that, the sleeper 4 is carried out to the side through the rail - the movement Va of the gripper 3 with the sleeper 4 by the hydraulic cylinder 8 along the guide 7.

FIG. 4 shows two hinges 9,

0 because they are necessary for the removal of sleepers in any direction. If the left hinge 9 is released, the sleeper can be carried over the rail 2 to the left, since with respect to the right hinge 9, the hydraulic cylinder 10 guides 7 turns in a clockwise direction. When connecting the guide 7 to the left hinge, the guide 7 by the hydraulic cylinder 10 can rotate relative to the left hinge 9 counterclockwise

The arrows and the sleeper 4 can be moved to the right. In each case, the guide 7 is connected with only one hinge 9. With two hinges 9, the guide 7 can only be connected in the transport position to give greater rigidity and to remove the load from the hydraulic cylinder 10. Similarly, the device of FIG. 1. The device of FIG. 2 can work without detaching the guide 7 from any hinge 9, since part of the hinge 9 is the rail head 2 and the guide is simply mounted with its grooves on the heads of these rails 2. The choice of the hinge 9, with respect to which the guide 5 rotates 7 and accordingly, the direction in which the sleeper 4 is placed is determined by which way, under the rails 2, the sleeper 4 is shifted before it is rotated relative to the hinges 9. If the sleeper 4 is shifted

0 to the left, then it will be turned by the hydraulic cylinder 10 counterclockwise relative to the left hinge 9, followed by moving it to the right, and if the sleeper 4 is shifted to the right, then it will be the hydraulic cylinder 10

5, rotate clockwise with respect to the right hinge 9, followed by. the removal of this tie 4 to the left.

In order to install a new tie with scrapers 15, the gripper 3 makes preparation and disassembly of the bed under the tie in the ballast. Then, a new sleeper 4 is gripped by its movements / s, V2, Vi in the reverse order than in the operation to remove the sleeper. Work capture 3 as a gray fer or scrapers 15, it is possible to produce ballasting. The presence of the hinge 11 allows the rotation of the guide 7 with respect to the additional hinge 9 located far from the rail 2 when the sleepers 4 are self-installing

the minimum expenditure of energy on the deformation of the ballast (without an emphasis sleepers in the ballast). The hinge pin 12 can be fastened with quick-detachable fingers and hold the grip 3 from the spontaneous rotation of the grip 3 relative to the hinge 11 when operating with the scraper 15 grip.

This design of the device allows the replacement of sleepers in conditions where the carrying of sleepers to the side from under the rails is impossible. The proposed design allows for the replacement of sleepers in the traditional way — by removing the sleepers from under the rails with one VL movement. In this case, the grip 3 clamps the end of the sleepers 4.
