Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field related to rail construction, in particular to a milling device for rail welds. Background Art
[0002] Rail welds are a critical component of railway tracks, connecting two sections of rail and ensuring the continuity and integrity of the track. The quality of the welds is directly related to the safe and stable operation of the railway. Therefore, regular and rigorous nondestructive testing of rail welds is crucial. After welding, the rails produce a relatively rough weld surface, necessitating weld milling. Weld milling is a process used to improve the appearance and smoothness of welded joints. It typically involves using a milling cutter or other cutting tool to remove excess material from the weld area to achieve the desired geometry and surface roughness. However, this process still suffers from the following drawbacks in practical use:
[0003] During the milling process of rail welds, due to the long rails and the concave position, it is necessary to manually push the milling equipment to the corresponding position and align the milling position. During the milling process, there are many operation steps, which is not convenient to use during the work process.
[0004] During the milling process of rail welds, the corresponding milling equipment is directly transported. During the milling process, when the milling operation is in progress, the milling equipment milling structure is accurately moved to the milling position when manually pushed. The operator is required to accurately limit the positioning. During the operation, accurate milling is not convenient enough. Utility Model Content
[0005] The purpose of the utility model is to provide a milling device for rail welds. By arranging side limit plates, a top support plate, a motor 1, a motor 2 and a rail body, the utility model solves the problems of rail welds having many milling steps, being inconvenient to use and not being convenient to perform milling accurately during the milling process.
[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:
[0007] The utility model discloses a milling device for a rail weld, comprising a side limit plate, a top support plate, a motor 1, a motor 2 and a rail main body, wherein a limit block is fixed on one side of the side limit plate, and the top of the side limit plate and the limit block are jointly fixed with a top support plate, and the bottom of the top support plate is provided with a rail main body, and the top of the top support plate is fixed with a motor 1, and the center of the motor 1 is arranged above the center line of the top of the rail main body and parallel to the long side, and a motor 2 is fixed at a corner of the top support plate. When working, the limit block is fixed thereon through the side limit plate, and the position between the side limit plate and the rail main body is determined by limiting the position of the limit block, and the motor 1 and the motor 2 are fixed thereon through the top support plate, and the Ganfeng structure on the top of the milling rail main body is driven to rotate by the motor 1, and the structure for milling between the upper chord and the lower chord of the milling rail main body and one side of the web is driven to rotate by the motor 2.
[0008] Furthermore, the limit block is arranged on the side of the side limit plate close to the rail body, and a clamping block is fixed to the lower part of the side of the limit block away from the side limit plate. The clamping block is movably connected to the side of the web between the upper chord and the lower chord on one side of the rail body. The limit block enters the side of the web between the upper chord and the lower chord on one side of the rail body through the clamping block, so that when working, the limit block determines the position of the side limit plate.
[0009] Furthermore, a vertical push handle is fixed on the side of the side limit plate away from the side limit plate, and a push handle is fixed on the edge of the top support plate away from the motor 2, so that the top support plate can be pushed and pulled to drive the movement.
[0010] Furthermore, a rotating hole is vertically opened in the top support plate at the center of the bottom of motor one and motor two, and two rotating plates are fixed to the bottom of the side limit plate. The two rotating plates are arranged above the rail body, and the rotating plates rotatably connect the rolling wheels thereto.
[0011] Furthermore, the center of the rotating plate is set above the transverse center line of the top of the rail body, and both sides of the rotating plate are rotatably connected with rolling wheels, and the rolling wheels are set on the top of the rail body, so that when pushed, the rolling wheels roll, driving the side limit plates and the top support plate to move.
[0012] Furthermore, a rotating shaft 1 is fixed to the output end of the motor 1, a milling cutter 1 is fixed to the bottom end of the rotating shaft 1, and the bottom end of the milling cutter 1 is arranged on the top of the rail body; a rotating shaft 2 is fixed to the output end of the motor 2, a milling cutter 2 is fixed to the bottom end of the rotating shaft 2, and the milling cutter 2 is movably connected to one side of the web between the upper chord and the lower chord on one side of the rail body; the rotating shaft 1 and the rotating shaft 2 are respectively inserted into two rotating holes, and the milling cutter 1 is driven to rotate by the motor 1, and the milling cutter 2 is driven to rotate by the motor 2.
[0013] The utility model has the following beneficial effects:
[0014] The utility model solves the problem that the rail weld has many milling steps and is inconvenient to use during the milling process by arranging side limit plates, a top support plate and a rail body. Motor one drives rotating shaft one to drive milling cutter one to rotate, so that when milling cutter one rotates, as the top support plate moves to the weld between the rail bodies, milling cutter one mills the gap at the top of the rail body. At the same time, rotating shaft two is driven to rotate by motor two, driving milling cutter two to rotate, so that the weld between the upper chord and the lower chord of the rail body and the surface of one side of the web are milled, and then the side limit plates are removed from the surface of the rail body and then placed on the other side of the rail body, so that the weld on the surface of the rail body is fully milled, so that the rail weld has fewer milling steps during the milling process and is convenient to use.
[0015] The utility model solves the problem that it is not convenient to accurately mill the rail weld during the milling process by arranging the side limit plate, the top support plate, the motor one, the motor two and the rail body. The side limit plate is arranged on one side of the rail body, and the side limit plate is continuously pushed so that the limit block and the clamping block on the side limit plate move toward the rail body, so that the clamping block enters between the upper chord and the lower chord of the rail body until the clamping block contacts the web. Then, the two pushing handles are held to push the side limit plate and the top support plate. At this time, the rolling wheels are supported on the top of the rail body. When the two pushing handles are pushed, the side limit plate and the top support plate run smoothly with the surface of the rail body, and after work, the pushing handles are pulled horizontally in the direction of the length of the rail body to remove the side limit plate. When working, accurate milling only requires supporting the side limit plate and the top support plate in place, and milling is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS
