Description

Technical Field

[0001] The utility model relates to the technical field of railway maintenance, in particular to a railway sleeper lifting structure. Background Art

[0002] Sleepers, also known as sleepers, are also a type of railway accessories. The sleepers not only support the rails, but also keep the rails in place and transfer the huge pressure from the rails to the ballast.

[0003] Rails and sleepers are prone to sinking under the long-term rolling of trains, so the sleepers need to be lifted and maintained.

[0004] Chinese patent CN213804662U discloses a track structure lifting device, including a sleeve, a jack is arranged inside the sleeve, a pressure rod is movably connected to the side of the jack, a movable column is arranged on the top of the jack, and the movable column is inserted into the sleeve, a groove is provided at the bottom of the movable column, and the top of the jack is located in the groove, and a feed trough is provided on the top of the movable column in the vertical direction. The utility model has a feed trough, a stick-like object such as a crowbar is inserted into the pry hole, and the crowbar is pushed in the horizontal direction, so that the jack is extended under the action of the movable column to lift the movable column, and then the sleeper is lifted through the second annular baffle, and then a polymer is injected into the feed trough, and the injected polymer passes through the discharge hole outside the sleeve to the gap between the sleeper and the ballast, so that the gap generated when the track is lifted can be filled more conveniently while the track is lifted, thereby improving work efficiency.

[0005] The above patent lacks a leveling function when in use. Since the roadbed under the sleeper is mostly paved with stones, its flatness is poor. The above patent lifts the left and right ends of the sleeper by two jacks. If it is not level, it will cause differences in the heights of the left and right ends of the sleeper. In addition, since the jacks are mostly manually operated, people cannot ensure that the two jacks lift the left and right ends of the sleeper to the same height, which may cause one end of the sleeper to be higher than the other, affecting use. Therefore, in view of the above situation, it is urgent to develop a railway sleeper lifting structure that is easy to level and can simultaneously lift the left and right ends of the sleeper to ensure that the left and right ends of the sleeper are lifted to the same height and prevent the sleeper from tilting, so as to overcome the shortcomings in current practical applications and meet current needs.

In summary, the utility model is convenient for leveling, and the left and right ends of the sleeper are lifted synchronously, so as to ensure that the left and right ends of the sleeper are lifted to the same height, and the sleeper is prevented from being skewed.

The two hydraulic cylinders 2 are electrically connected to the hydraulic cylinder controller 8 through the wire 9. The tops of the two lifting plates 3 support the sleepers 10. When in use, first clear a placement groove on the roadbed below the left and right ends of the sleepers 10. And separate the connecting block 4 and the adapter sleeve 5, so that the two lifting plates 3 are in a separated state, then, place a leveling mechanism 1, hydraulic cylinder 2 and lifting plate 3 under the left end of the sleeper 10, and then place another leveling mechanism 1, hydraulic cylinder 2 and lifting plate 3 under the right end of the sleeper 10, at the same time, insert the connecting block 4 into the adapter sleeve 5, and then fix the connecting block 4 and the adapter sleeve 5 together by the limiting mechanism 6, and then observe whether the spirit level 7 is horizontal. If it is not horizontal, adjust the height of the hydraulic cylinder 2 and the lifting plate 3 through the leveling mechanism 1. After adjustment, control the two hydraulic cylinders 2 to move simultaneously through the hydraulic cylinder controller 8, and drive the two lifting plates 3 to lift the left and right ends of the sleeper 10 at the same time through the two hydraulic cylinders 2, so that the left and right ends of the sleeper 10 are lifted to the same height, thereby preventing the sleeper 10 from being skewed.

[0024] The leveling mechanism 1 includes: a base 101, a threaded sleeve 102, a threaded rod 103, a mounting seat 104, a toggle rod 105 and a limit rod 106. The threaded sleeve 102 is rotatably connected to the base 101, and a threaded rod 103 is installed in the threaded sleeve 102 to penetrate the threaded sleeve.

The bottom of the threaded rod 103 is fixed with a limit rod 106 that penetrates the base 101, and the limit rod 106 slides with the base 101. The base 101 is provided with a limiting groove 1011 for the limiting rod 106 to move up and down. The limiting rod 106 limits the movement of the threaded rod 103 so that it cannot rotate but can only move in a straight line. A plurality of toggle rods 105 are fixed to the outside of the threaded sleeve 102. When in use, the threaded sleeve 102 is driven to rotate by the toggle rod 105, and the threaded sleeve 102 is rotated to drive the threaded rod 103 and the mounting seat 104 to move up and down, and the mounting seat 104 drives the hydraulic cylinder 2 to move up and down.

[0026] Working principle: When the railway sleeper lifting structure is used, first clear a placement groove on the roadbed below the left and right ends of the sleeper 10, and separate the connecting block 4 and the adapter sleeve 5, so that the two lifting plates 3 are in a separated state, and then place a leveling mechanism 1, a hydraulic cylinder 2 and a lifting plate 3 under the left end of the sleeper 10, and then place another leveling mechanism 1, a hydraulic cylinder 2 and a lifting plate 3 under the right end of the sleeper 10. At the same time, insert the connecting block 4 into the adapter sleeve 5, and then use the limiting mechanism 6 to fix the connecting block 4 and the adapter sleeve 5 together, so as to fix the two lifting plates 3 together, and then observe whether the spirit level 7 is level. If it is not level, The threaded sleeve 102 is driven to rotate by the toggle rod 105, and the threaded sleeve 102 is rotated to drive the threaded rod 103 and the mounting seat 104 to move up and down, and the mounting seat 104 drives the hydraulic cylinder 2 to move up and down, so as to adjust the height of the hydraulic cylinder 2 and the jacking plate 3. After the adjustment, the two hydraulic cylinders 2 are controlled to move simultaneously by the hydraulic cylinder controller 8, and the two jacking plates 3 are driven by the two hydraulic cylinders 2 to jack up the left and right ends of the sleeper 10 at the same time, so that the left and right ends of the sleeper 10 are lifted to the same height, thereby preventing the sleeper 10 from being skewed. After the sleeper 10 is lifted, the roadbed material is filled under the sleeper 10 to support it.
