Fig. 1-4 are schematic structural diagrams of a positive track lifting and lining device according to an embodiment of the present application. The embodiment of the application provides a positive track lifting and shifting device, which comprises a track lifting and shifting frame 100 and a track clamping mechanism;

the track lifting and lining frame 100 comprises a cross beam 110 and two track clamping pincers frames 120, wherein the two track clamping pincers frames 120 are respectively arranged at two ends of the cross beam 110;

the number of the rail clamping mechanisms is at least two, the at least two rail clamping mechanisms are respectively arranged on the two rail clamping pliers frames 120, and the rail clamping mechanisms are used for clamping the steel rail 400;

the top of the beam 110 is provided with a track lifting cylinder 111 and a track lining cylinder 112, and the track lifting cylinder 111 and the track lining cylinder 112 are respectively used for carrying out track lifting and track lining operations.

As a specific embodiment, the top of the beam 110 is connected to a track jack 111 and a track lining jack 112.

Illustratively, two rail clamping jaws 120 are respectively and vertically disposed at two ends of the beam 110, and the length direction of the beam is taken as the X axis, the length direction of the rail clamping jaws 120 is taken as the Y axis, then the X-Y plane is the horizontal plane, i.e. the plane in which the rail 400 is located, and the rail 400 is parallel to the Y axis direction. The lower end of the track lifting cylinder 111 is rotatably connected with the top surface of the cross beam 110, and the upper end is connected with the frame of the tamping car, and the track lifting cylinder 111 is in a vertical direction, namely in a direction vertical to an X-Y plane in general, or the track lifting frame 100 is subjected to certain displacement under the pushing of the track lifting cylinder 112, so that the track lifting cylinder 111 is inclined to a certain extent, and therefore the included angle between the track lifting cylinder 111 and the X-Y plane is close to 90 degrees.

The lower end of the track-shifting cylinder 112 is rotatably connected with the top surface of the cross beam 110, and the upper end is connected with the frame of the tamping car, so that the track-shifting cylinder 112 is in an inclined state, and when the track-shifting cylinder is extended or shortened, the track-shifting frame 100 can be pushed to move a certain distance in the horizontal direction, thereby achieving the purpose of track shifting.

The cross beam 110 may be connected to the rail clamp frame 120 by welding, screws, rivets, etc., so that the entire track lifting frame 100 forms a rigid unit to better transmit the track lifting force. And the length of the cross beam 110 can be adjusted according to the requirement so as to adapt to the track lifting and lining requirements of different track gauges. Such as 1676mm, 1435mm, and 1000 mm. Meanwhile, in order to enhance the strength of the connection between the beam 110 and the rail clamping jaw 120 and the rigidity in the X-axis direction, a rib plate 111 is further provided at the connection of the beam 110 and the rail clamping jaw 120.

The working process of the positive track lifting and lining device in the application is as follows:

after the track lifting device moves to a position requiring track lifting treatment along with the tamping car, at least two track clamping mechanisms act to clamp the left and right steel rails 400 at the same time, then the track lifting cylinder 111 shortens, the track 400 is lifted up through the track lifting frame 100 and the track clamping mechanisms, and meanwhile, the track lifting cylinder 112 acts (stretches or shortens) to move the track 400 for a certain distance in the horizontal direction. After the track lifting and track shifting operations are completed, the tamping car can perform tamping operation, and the track 400 is vertically lowered by the track lifting and track shifting device after the tamping operation is completed, so that the track 400 is positioned at the correct position.

In one possible embodiment, the rail clamping mechanism includes a mounting bracket 200, a rail clamp 210, and a rail clamping cylinder 230; the mounting frame 200 is disposed at the end of the rail clamping jaw 120, the rail clamping jaw 210 is rotatably disposed on the mounting frame 200, and the end of the rail clamping cylinder 230 is connected with the rail clamping jaw 210.

The mounting frame 200 is an i-shaped structure rotated 90 degrees, and is composed of three vertical mounting plates, wherein two mounting plates are identical or similar in size and shape and parallel to each other, and the other mounting plate is vertically connected between the two parallel mounting plates. The three mounting plates may be splice welded or integrally cast to form the mounting bracket 200. An outer side surface of the mounting frame 200 is vertically connected with the tail end of the rail clamping jaw 120, and the rail clamping jaw 120 can be provided with rail clamping mechanisms only at one end, and can also be provided with one rail clamping mechanism at both ends, so that the number of the rail clamping mechanisms in the positive line rail lifting device can be two, four and the like. The upper end of the rail clamping pliers 210 is rotatably connected to the upper end of the inside of the mounting frame 200, the position of the rail clamping pliers 210 close to the lower end is rotatably connected with the rail clamping oil cylinder 230, and the rail clamping oil cylinder 230 can drive the rail clamping pliers 210 to rotate in the X-Z plane after being stretched or shortened, so that the purpose of clamping or loosening the steel rail 400 is achieved.

In one possible embodiment, the number of the rail clamping pincers 210 arranged on the mounting frame 200 is two, and two ends of the rail clamping cylinder 230 are respectively connected with the two rail clamping pincers 210.

For example, when the number of the rail clamps 210 on one mounting frame 200 is two, the two rail clamps 210 are respectively located at two sides of the middle mounting plate among the three mounting plates of the mounting frame 200, and the two rail clamps 210 are symmetrically disposed inside the mounting frame 200, and two ends of the rail clamping cylinder 230 are respectively connected to positions of the two rail clamps 210 near the lower ends. When the rail clamping cylinder 230 is extended or contracted, the two rail clamps 210 are moved away from or toward each other, i.e., the rail 400 is released or clamped.

It should be understood that only one rail clamp 210 may be mounted on one mounting frame 200, and that when the number of rail clamps 210 is one, the rail clamps 210 are preferably disposed at positions outside the two rails 400. When the number of the rail clamping pincers 210 is one, one end of the rail clamping oil cylinder 230 is rotationally connected with the position, close to the lower end, of the rail clamping pincers 210, and the other end of the rail clamping oil cylinder is rotationally connected with the mounting frame 200, and when the rail clamping oil cylinder 230 stretches or shortens, the rail clamping pincers 210 rotate in an X-Z plane and are matched with other mechanisms to clamp and loosen the steel rail 400.

Fig. 5 is a schematic structural diagram of a rail clamp according to an embodiment of the present application. In one possible embodiment, the rail clamp 210 includes a clamp lever 211 and a rail clamp shaft 212, one end of the clamp lever 211 is rotatably connected to the mounting frame 200, the rail clamp shaft 212 is disposed at the other end of the clamp lever 211, and the rail clamp shaft 212 is rotatably provided with a rail clamp wheel 220 at an end remote from the clamp lever 211.

Illustratively, the top of the clamp bar 211 is vertically provided with a rotation shaft 213, which rotation shaft 213 is rotatably coupled to the mounting bracket 200 such that the clamp bar 211 can rotate in the X-Z plane. The axial direction of the clamping rail shaft 212 is parallel to the height direction of the clamping bar 211, and the clamping rail shaft 212 is disposed at one end of the clamping bar 211 away from the rotation shaft 213, i.e., at the bottom of the clamping bar 211. The clamping rail cylinder 230 is connected to the side of the clamping bar 211 near the position where it is connected to the clamping rail shaft 212.

In one possible embodiment, the diameter of the pinch roller 220 at the end proximal to the pinch shaft 212 is smaller than the diameter at the end distal to the pinch shaft 212.

Illustratively, since the longitudinal section of the rail 400 has a shape with a large top and a small bottom, the rail clamping wheel 220 having a large top and a large bottom can be hung on the bottom of the rail 400 when the rail clamping wheel 220 rotates to a position for clamping the rail 400 along with the clamp bar 211, so as to provide stable clamping force.

In one possible embodiment, one end of the clamping rail shaft 212 is screwed onto the clamping bar 211, and the clamping rail shaft 212 is screwed onto one end of the clamping bar 211 and is also screwed with a lock nut 214.

Illustratively, the position of the clamping shaft 212 on the clamping bar 211 is adjustable in a threaded manner to facilitate the height adjustment operation of the clamping wheel 220, and to accommodate the clamping requirements of different types of rails 400. When the clamping rail shaft 212 is adjusted to a required height by the clamp rod 211, the locking nut 214 can be rotated to tightly fit the clamp rod 211, so that the clamping rail shaft 212 is tightly locked on the clamp rod 211 to prevent loosening.

In one possible embodiment, the clamp rail shaft 212 is threaded with a screw gland 215 at a location near the clamp rail wheel 220.

Illustratively, the screw gland 215 is located above the rail clamping wheel 220, and when the position of the screw gland 215 on the rail clamping shaft 212 is adjusted, the up-down movement space of the rail clamping wheel 220 is determined. The screw gland 215 can limit the upward movement space of the rail clamping wheel 220 to avoid excessive shaking.

On the basis of the structure of the rail clamping pliers 210, after the rail clamping pliers 220 are used for a long time and severely worn, the rail clamping shaft 212 can be detached from the clamping rod 211, then the screw gland 215 is detached, the rail clamping pliers 220 can be detached from the rail clamping shaft 212, and after the rail clamping pliers 220 are replaced with new rail clamping pliers 210, the rail clamping pliers 210 can be installed on the installation frame 200 again, so that the whole rail clamping pliers 210 are prevented from being replaced every time, and the maintenance cost is saved.

In one possible embodiment, the bottom of the rail clamping jaw 120 is rotatably provided with a track-pulling wheel 121.

Illustratively, since the clamping rail mechanism is disposed at the end of the clamping rail clamp frame 120, when both ends of the clamping rail clamp frame 120 have the clamping rail mechanism, the track wheel 121 is located between the two clamping rail mechanisms. If the number of the track-lifting wheels 121 at the bottom of one track-clamping jaw 120 is two or more, the distance between two adjacent track-lifting wheels 121 is smaller, so that the positive track-lifting device can better adapt to the curved steel rail 400.

In the embodiment of the present application, the track roller 121 is provided with a protrusion on one side between the two rails, which protrusion can make the track roller 121 be located on the rail 400 at a position close to between the two rails 400 at a time when it is in contact with the rail 400. The rail wheel 121 can be matched with the rail clamping pliers 210 to clamp the steel rail 400 through the structure. Meanwhile, the track pulling wheel 121 is rotatably connected with the track clamping jaw frame 120 through a pin shaft, and the pin shaft can adjust the height of the track pulling wheel 121 on the track clamping jaw frame 120 through a mechanism such as an eccentric wheel so as to adjust the distance between the track pulling frame 100 and the steel rail 400, so that the height of the track clamping wheel 220 relative to the steel rail 400 can be changed to adapt to the steel rails 400 with different shapes.

In one possible embodiment, the beam 110 is provided with a draft sill 300 on the side.

Illustratively, the draft sill 300 is attached to a central location on the side of the cross beam 110, and the ends of the draft sill 300 are attached to the frame of the tamping car so that the entire positive track jack moves with the tamping car.

In one possible embodiment, the traction beam 300 is rotatably connected with the cross beam 110, the inclined support beams 310 are disposed at both sides of the traction beam 300, and a return spring is disposed at a contact position of the cross beam 110 and the inclined support beams 310.

Illustratively, the return spring may be an air spring, a rubber spring, a metal coil spring, or the like, preferably an air spring. When the angle between the traction beam 300 and the cross beam 110 is changed due to the traction influence of the tamping machine, the elastic force exerted on the cross beam 110 by the return spring is not the same, and the cross beam 110 can be quickly returned by the rotation moment generated by the elastic force difference.

In one possible embodiment, the number of the jack cylinders 111 is at least two, and the two jack cylinders 111 are respectively rotatably disposed at both ends of the top of the beam 110.

Illustratively, the upper ends of the two track cylinders 111 may be rotatably connected to both ends of the frame bottom of the tamping car, respectively.

In one possible embodiment, the number of track cylinders 112 is two, and the two track cylinders 112 are respectively rotatably disposed at two ends of the top of the beam 110.

Illustratively, the upper ends of the two track cylinders 112 may be rotatably connected to respective ends of the frame bottom of the tamping car. In particular, when the lifting cylinder 111 is in a vertical state, the lower end of the lifting cylinder 111 is connected with one end of the cross beam, and the upper end is also connected with one end corresponding to the frame of the tamping car. One end of a cross beam at the lower end of the track shifting cylinder 112 is connected, and the upper end of the track shifting cylinder is connected with the other end of the frame of the tamping car, so that the track shifting cylinder 112 is in an inclined state.
