Problems solved by technology
[0003] At present, the way to repair the arch on the track slab in the market is to use a jack to support the support layer. With the overall setting, the height of the trough cannot be controlled. If the steel frame is too high, it cannot be placed vertically in the trough. If the steel frame is too low, it will not be able to play a supporting role. It is necessary to place pads on the top, and the placement of the pads is also very difficult. Therefore, in view of the above problems, a device and method for arch regulation on track slabs are proposed

The invention relates to the technical field of railways, in particular to a track plate upward arching renovation device and method, the track plate upward arching renovation device comprises a foundation bed and a supporting layer, a groove is formed in the foundation bed, a jack and a supporting mechanism which are distributed left and right are arranged in the groove, and the supporting mechanism comprises a supporting plate and a supporting block; supporting blocks distributed left and right are fixedly connected to the lower end face of the supporting plate, threaded rods are fixedly connected to the lower end faces of the supporting blocks, and a driven rotating cylinder and a supporting rod which are distributed up and down are spirally connected to the outer side of the threaded rod located on the left side. The outer side of the threaded rod located on the right side is spirally connected with a driving rotating cylinder and a supporting rod which are distributed up and down;according to the device, through the arrangement of the supporting plate, the threaded rod, the driving rotating cylinder and the gear, the driving rotating cylinder is driven by the handle to rotate, so that the supporting plate moves upwards, the purpose of jacking is achieved, the situation that a steel frame is too high or too low does not need to be worried about, the supporting effect of the supporting mechanism is very convenient, and the construction period is greatly shortened.
Description
technical field [0001] The invention relates to the technical field of railways, in particular to a device and method for regulating arches on track slabs. Background technique [0002] The arch on the track slab mainly occurs at the transition section of road bridge and road culvert, and a small part occurs at the subgrade of the interval. Cause surface sealing layer cracking, road shoulders, slope protection damage, staggered platform, culvert back cracks and culvert cap stones also have obvious damage, etc. The cause of the disease: after research, the upper arch is divided into mudstone foundation, expansive substances, salt and other substances. of expansion. [0003] At present, the way to repair the arch on the track slab in the market is to use a jack to support the support layer. With the overall setting, the height of the trough cannot be controlled. If the steel frame is too high, it cannot be placed vertically in the trough. If the steel frame is too low, it wi...
