Description

Technical Field

[0001] The utility model belongs to the technical field of railway open car maintenance, and in particular relates to a special clamp for welding and repairing railway open cars used by steel enterprises. Background Art

[0002] As we all know, railway open wagons are one of the main transportation equipments of steel enterprises, mainly used for the transshipment of slag, coke and other items and goods in the factory. Due to the harsh operating environment of railway open wagons, corrosion and external forces, holes and deformations appear on the side walls, side beams and side columns of the car body structure, which need to be repaired by welding through digging and patching.

[0003] At present, there are the following technical problems in welding reinforcement plates at damaged parts of railway open car box structures by digging and patching:

[0004] 1. The surface of the repaired part is uneven: When the side wall, side beam, or side column is damaged, the damaged part is deformed by heat when it is dug out by gas welding cutting. The cut is not on the same plane and needs to be adjusted.

[0005] 2. The surface of the reinforcement plate is uneven: When cutting the reinforcement plate, due to the heat, the cut of the reinforcement plate is not on the same plane and needs to be adjusted.

[0006] 3. Low operating efficiency: When welding two cuts that are not on the same plane together, adjustments need to be made. Generally, baking or hammering is used, which results in low operating efficiency.

[0007] 4. Occupy resources: welding after baking and tapping. Tapping requires mastering the temperature, and the waiting time for welding is long. Generally, three people are required to cooperate, which occupies resources, and baking wastes resources.

[0008] In summary, the current technical problems of welding reinforcement plates on damaged parts of railway open car box structures through digging and patching mainly focus on the uneven surface of the repaired parts, the uneven surface of the reinforcement plates, low operating efficiency, and resource occupation. Therefore, it is necessary to propose a special fixture for welding and repairing railway open cars for steel enterprises to solve the above technical problems and improve the quality and efficiency of welding and repair.

[0012] A push rod, the outer wall of which is provided with external threads matching the three screw holes;

[0013] The adjusting rod has a threaded hole at the free end of the first supporting arm for connecting with the adjusting rod.

[0014] Preferably, the sizes of the No. 1 screw hole, the No. 2 screw hole and the No. 3 screw hole are the same.

[0015] Preferably, the push rod comprises a screw rod with external threads, and a locking ring is provided at one end of the screw rod.

[0016] Preferably, the other end of the screw rod is a conical structure.

[0017] Preferably, the screw rod and the locking ring are an integrally formed structure.

[0018] Preferably, the adjustment rod is a T-shaped structure.

[0019] The advantages and positive effects of the utility model are:

[0020] 1. When the surface of the repaired part or the reinforcing plate is uneven, the utility model changes from traditional baking and knocking to using a special clamp, thereby reducing the fuel energy used for baking.

[0021] 2. When the surface of the repaired part or the reinforcing plate is uneven, the utility model changes the baking and knocking to using a special clamp, thereby reducing the human resources occupied by the knocking after baking.

[0022] 3. The utility model can fix two cuts that are not on the same plane, reducing the resources occupied by manual cooperation. It reduces the baking and hammering operations, improves the operation efficiency, and reduces the occupation of human resources.

[0023] In summary, the technical solution of the utility model has obvious advantages and effects in the process of welding repair by digging and patching when holes and deformations appear on the side walls, side beams and side columns on the box structure of the railway open car body.

[0034] In order to make the above-mentioned purpose, design control system and advantages of the utility model more clear, the utility model is further described in detail in combination with the embodiments below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0035] like Figures 1 to 4 As shown, the technical solution of the utility model is:

[0036] A special clamp for welding and repairing railway open cars used in steel enterprises mainly comprises three parts: a U-shaped clamp 1, a push rod 2 and an adjusting rod 3;

[0037] The structure of the U-shaped clamp 1 is as follows: the U-shaped clamp 1 comprises a middle arm, a first arm and a second arm vertically connected to the middle arm; the first arm and the second arm are parallel to each other; the length of the first arm is less than the length of the second arm; a No. 1 screw hole 1-1 is provided on the first arm; a No. 2 screw hole 1-2 and a No. 3 screw hole 1-3 are provided on the second arm; the No. 1 screw hole 1-1 and the No. 3 screw hole 1-3 are coaxial; the central axes of the No. 2 screw hole 1-2 and the No. 3 screw hole 1-3 are parallel to each other;

[0038] A push rod 2, wherein the outer wall of the push rod 1 is provided with an external thread matching with three screw holes;

[0039] The adjusting rod 3 has a threaded hole at the free end of the first arm for connecting the adjusting rod 3 .

[0040] In order to meet the size requirement of a single push rod 2, the sizes of the No. 1 screw hole, the No. 2 screw hole and the No. 3 screw hole can be completely the same.

[0041] For easy operation, the push rod 2 includes a screw rod 2-1 with external threads, and a lock ring 2-2 is arranged at one end of the screw rod 2-1. The other end of the screw rod 2-1 is designed to be a conical structure.

[0042] The screw rod 2-1 and the locking ring 2-2 are an integrally formed structure.

[0043] The adjusting rod 3 is a T-shaped structure.

[0044] The following is a detailed description of the working process in conjunction with the accompanying drawings:

[0045] like Figure 5 As shown,

[0046] When in use, the top rod 1 is used to fix the part 5 of the vehicle body side wall, side beam and side column that needs to be welded, so that the reinforcing plate 4 and the part 5 that needs to be welded are in the same plane.

[0047] like Figure 6 As shown,

[0048] When in use, the reinforcing plate 4 is fixed by the push rod 1 so that the reinforcing plate 4 and the part 5 to be welded are in the same plane.

[0049] like Figure 7 As shown,

[0050] The clamp body is provided with an adjusting rod 3, which has a prying effect, and pries the reinforcement plate or the welding repair part on a uniform plane to assist the welding repair.

[0051] like Figure 8 As shown,

[0052] The clamp body does not have an adjustment rod 3, which has a prying effect, and pries the reinforcement plate or the welding repair part on a uniform plane to assist the welding repair. The difference from the previous solution is that the space restriction requirement is met.

[0053] This tool can significantly improve the efficiency and quality of railway vehicle maintenance, reduce labor costs and fuel resource usage, and effectively improve the work experience.

[0054] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are within the scope of the technical solution of the present invention.
