[0004] Specifically, a double-track steel box girder sliding system of the utility model comprises two sliding tracks parallel to each other arranged on the sliding track beam, sliding shoes slidingly arranged on the two sliding tracks, and a hydraulic crawler arranged on the two sliding tracks and connected to the sliding shoes;

[0005] The sliding shoe comprises a sliding shoe body, a cylinder sleeve structure arranged on the sliding shoe body, and a cylinder cap structure arranged on the cylinder sleeve structure.

[0006] On the basis of the above scheme, the sliding shoe is a door-type structure, and the bottom of the sliding shoe is slidably installed on two sliding tracks to form a double-track structure;

[0007] Each sliding track is equipped with a hydraulic crawler.

[0008] In addition to the above solutions, it also includes:

[0009] A vertical cylinder and a guide cylinder are arranged in the cylinder sleeve structure and are used to adjust the position of the steel box beam segment.

[0010] On the basis of the above scheme, the hydraulic crawler includes a hydraulic cylinder and a clamp;

[0011] The bottom of the hydraulic oil cylinder is rotatably connected to the clamp through a base, and the top of the hydraulic oil cylinder is connected to the tail of the sliding shoe body through a pin shaft.

[0012] On the basis of the above solution, the hydraulic crawler is a self-locking hydraulic crawler.

[0013] The double-track steel box girder sliding system provided by the utility model has the advantages of small sliding equipment volume, light weight and large carrying capacity. It is particularly suitable for horizontal sliding of large-tonnage components and equipment in a narrow space or indoors. It abandons the traditional reaction frame and adopts a clamp to clamp the track to act as an automatic shifting reaction frame for pushing. BRIEF DESCRIPTION OF THE DRAWINGS
