AI Technical Summary
When loading and unloading goods, railway open wagons are prone to bending and deformation of the floor, beams, side walls and end walls due to improper operation. Existing straightening equipment is difficult to effectively fix the wagons, making the straightening operation unsafe and difficult.
A support stool for straightening tires on railway open wagons was designed. It adopts a gear and rack structure and an anti-detachment and flipping plate. The four corners of the vehicle are fixed by the gear and rack mounting seat and the rack hook device. Combined with the reinforcing plate and the slide rail structure, it ensures that the vehicle does not shift during the straightening process.
It enables safe and reliable operation during the straightening process of railway open wagons, prevents vehicles from moving forward, backward, left, or right, simplifies the process of unloading and lifting the wagons, and improves straightening efficiency and safety.

The wagon has the end wall, the side wall, the chassis and no roof, and is the top open wagon, which is the main type vehicle in railway transportation. Since the floor, the beam, the side wall and the end wall are bent and deformed due to improper operation during loading and unloading, correction is needed during the factory repair to ensure that the vehicle meets the railway wagon factory repair regulations. UTILITY MODEL CONTENTS
[0004] The utility model aims at solving the above-mentioned defects, and provides a bench for railway open wagon correction.
[0005] In order to overcome the defects in the background art, the utility model adopts the technical scheme that the bench for railway open wagon correction includes a bench support fixed on the ground, a gear and rack mounting seat is arranged at the upper end of the bench support, a gear is arranged on the gear and rack mounting seat, the gear is connected to the side surface of the gear and rack mounting seat through a fixed shaft, a rack hooking device is arranged at the upper end of the gear and rack mounting seat, the rack hooking device includes a rack engaged with the gear at the lower end and a hook arranged at the upper end, and a anti-falling turnover plate is further arranged at the upper end of the gear and rack mounting seat, one end of the anti-falling turnover plate is connected to the gear and rack mounting seat through an anti-falling turnover plate shaft, and the other end abuts against one side of the rack hooking device.
[0006] According to another embodiment of the utility model, a triangular reinforcing plate is further fixedly connected to the side surface of the bench support.
[0007] According to another embodiment of the utility model, a protrusion for placing the anti-falling turnover plate is arranged on one side of the rack hooking device.
[0008] According to another embodiment of the utility model, a hand wheel is further fixedly connected to the fixed shaft.
[0009] According to another embodiment of the utility model, the rack hooking device is installed above the gear and rack mounting seat through a slide rail structure.
[0010] The utility model discloses a trestle for railway open wagon correction mainly utilizes the hooking device on the trestle to fix the four corners of the vehicle, which is convenient for the oil cylinder to correct the floor, crossbeam, side wall and end wall of the vehicle and prevents the vehicle from moving up and down, forward and backward and left and right, and facilitates the vehicle to be unloaded and lifted, and the operation is safe and reliable. BRIEF DESCRIPTION OF DRAWINGS
[0011] The utility model will be further explained in connection with the drawings and embodiments.
[0012] Figure 1 It is the structural schematic diagram of the utility model;
[0013] Among them: 1, trestle support, 2, gear rack mounting seat, 3, gear, 4, fixed shaft, 6, rack hooking device, 7, anti -drop turnover board, 8, anti -drop turnover board axle, 9, anti -drop turnover board mounting seat, 10, reinforcing plate, 11, open wagon body. DETAILED DESCRIPTION
[0014] In order to make the purpose, technical scheme and advantage of the utility model embodiment clearer, the technical scheme in the utility model embodiment will be clearly and completely described below in connection with the utility model embodiment, obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiment. The embodiment in the basic utility model, all other embodiments obtained by the ordinary skill in the art without creative labor are within the protection scope of the utility model.
[0015] As Figure 1 Shown, including fixed on the trestle support 1 of ground, the upper end of trestle support 1 is equipped with gear rack mounting seat 2, the gear rack mounting seat 2 is equipped with gear 3, is connected in the side of gear rack mounting seat 2 by fixed shaft 4, the upper end of gear rack mounting seat 2 is equipped with rack hooking device 6, and the rack hooking device 6 includes the rack of the lower end and the gear 3 meshing, and the hook of the upper end setting, the upper end of gear rack mounting seat 2 is further equipped with anti -drop turnover board 7, and one end of anti -drop turnover board 7 is connected on gear rack mounting seat 2 through anti -drop turnover board axle 8, and the other end is against the side of rack hooking device 6. The structure satisfies the railway open wagon correction operation use, solves the security problem that open wagon correction is easy to cause vehicle displacement, solves the problem of omnibearing correction difficulty. The trestle adopts gear rack structure and anti -drop device, fixes the four corners of the vehicle, guarantees the vehicle locking, and facilitates the vehicle to be unloaded and lifted.
