[0025] In order to make the purpose, principle and structure of the utility model more clear and obvious, the following further elaboration is made in combination with the drawings and specific embodiments.

[0026] Referring to Figures 1 to 7 The utility model provides rail banger equipment acting on rail waist of steel rail.

[0027] The utility model is composed of rail banger main body 1, limit block 2, limit bolt 3 and lifting handle 4.

[0028] Rail banger main body 1 is a concave-shaped metal structure, which is placed on the steel rail in a straddling manner, and its contact surface with the steel rail is designed to fit the rail top, and the side surface has four threaded through holes for the limit bolt 3 to pass through. Limit block 2 is a profiled metal part, which is shaped like a rail waist on the side close to the steel rail and fits the internal recess structure of the rail banger main body 1 on the side close to the rail banger main body 1, and has a plurality of square grooves 6 on the side close to the steel rail to reduce the weight. Limit bolt 3 is a bolt structure, which passes through the through hole of the rail banger main body 1 and cooperates with the threaded through hole, and is used to adjust the distance between the limit block 2 and the rail banger main body 1. After the limit bolt 3 is tightened, the limit block 2 clamps the steel rail, so that the rail banger can transmit the impact force of the rail banger trolley to the rail waist of the steel rail during stress dispersion operation. Lifting handle 4 is made of a hollow metal pipe and is located on the side of the rail banger main body 1, which is convenient for the operator to grasp when the equipment is transferred.

[0029] The limit block 2 is further provided with an impact block 5 on any side surface before and after the limit block 2 is separated from the steel rail and the rail banger main body 1. One side of the impact block 5 is fixedly connected with the limit block 2, and the other side extends out of the recess structure of the rail banger main body 1, so that the impact block 5 protrudes from the rail banger main body 1, and the impact block 5 is arranged at the lower part of the limit block 2 close to the steel rail. The other side of the impact block 5 is a flat surface or a concave surface or a convex surface or a shape surface similar to the impact head of the existing rail banger trolley. The design has the effect that the stress dispersion force of the rail banger trolley can better act on the part where the limit block 2 is closely attached to the rail waist of the steel rail, reducing the loss of force in the transmission process and the force being decomposed due to different force points, so that more force can be involved in the stress dispersion operation for the rail waist of the steel rail. Compared with the existing technology which only targets the rail top as the force point for stress dispersion, a more uniform stress dispersion operation effect can be obtained.

[0030] Specifically, the method is as follows:

[0031] Step 1: The stress dispersion operator carries the rail banger equipment and the rail banger trolley of the utility model to the operation area, and measures the steel rail information according to the urban rail transit stress dispersion standard.

[0032] Step 2: The rail buster body 1 is placed on the rail as required.

[0033] Step 3: The limiting bolt 3 is loosened, the limiting block 2 is put into the gap between the rail buster body 1 and the rail web, the limiting bolt 3 is tightened, the position of the limiting block 2 and the rail buster body 1 is adjusted, and the rail buster is ensured to be fixed on the rail.

[0034] Step 4: The rail buster is repeatedly hit by the rail buster trolley, and the rail stress dispersion work is completed.

[0035] Step 5: After the work is completed, the limiting bolt 3 is loosened, the limiting block 2 is taken out, the rail buster body 1 is removed, the equipment is moved to the next work point, and steps 2-4 are repeated until the stress dispersion work of the seamless line is completed.

[0036] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent substitutions or changes according to the technical scheme and novel concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
