Description

Technical Field

[0001] The utility model relates to the technical field of railway maintenance and fixing, in particular to a rail fixing and reinforcing device for railway line maintenance. Background Art

[0002] With the continuous development of railway construction, a crisscrossing network of railways, roads and underground engineering is increasingly forming. In order to ensure the normal operation of the railway, it is inevitable to maintain and reinforce the rails of the railway lines. The reinforcement of the rails plays a vital role in the construction of railways, not only to make the train safer during travel, but also to protect the lives of passengers on the train.

[0003] Rails are a kind of railway facilities used on railways, and cooperate with switches and turnouts to allow trains to run without turning. Tracks are usually composed of two balanced rails. After long-term use, they will be partially broken because they cannot bear the weight. At this time, workers are required to perform maintenance welding. However, the welding of the rails must make the two rails parallel. In order to facilitate the welding of rails, they are generally welded on site, which results in different welding areas of different rails, causing the fixed structure to be easily tilted when placed, so that the welded rails cannot be at the same level. The quality of welding does not meet the best standards, which reduces the maintenance quality of the rails. For this reason, we propose a rail fixing and reinforcement device for railway line maintenance. Utility Model Content

[0004] The utility model aims to provide a rail fixing and reinforcing device for railway line maintenance, so as to solve the problem in the background technology mentioned above that when the rails are welded, due to different areas, the fixing structure is prone to tilt during use, resulting in the rails not being at the same level during welding, thus affecting the welding quality.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a rail fixing and reinforcement device for railway line maintenance, comprising a support frame, a linkage box is slidably provided in the inner cavity of the support frame, clamping plates are provided on both sides of the inner cavity of the linkage box, adjustment components are fixedly connected on both sides of the support frame, the bottom end of the adjustment component is sleeved and connected to a support base plate, a laser level is inlaid and connected at the bottom end of one side of the inner cavity of the support frame, and an anti-slip pad is fixedly connected to the bottom end of the support base plate.

[0006] Preferably, the adjustment assembly comprises an adjustment box, a third adjustment screw is threadedly connected to the top end of the adjustment box, a nesting shaft is rotatably connected to the bottom end of the third adjustment screw, and the nesting shaft is nested and connected to the upper surface of the support base plate.

[0007] Preferably, a first adjusting screw for adjusting the height of the linkage box is threadedly connected to the top of the support frame, a rotating connecting shaft is rotatably connected to the bottom surface of the first adjusting screw, and the rotating connecting shaft is nested in the upper surface of the linkage box.

[0008] Preferably, limiting sliding grooves are provided on both sides of the inner cavity of the support frame, and the limiting sliding grooves transversely penetrate the support frame and extend to the other side.

[0009] Preferably, both sides of the linkage box are fixedly connected with limiting sliding blocks adapted to the limiting sliding grooves, the upper end of the inner cavity of the linkage box is laterally rotatably connected with a second adjusting screw, and both ends of the second adjusting screw are respectively threadedly connected to the upper end of the clamping plate.

[0010] Preferably, a transmission rod is rotatably nested on one side of the limit sliding block, and the inner side of the transmission rod is fixedly connected to one side of the second adjusting screw.

[0011] Preferably, a limiting slide bar is provided at the lower end of the inner cavity of the linkage box, and the lower ends of the clamping plates are respectively sleeved on the surfaces of the limiting slide bar.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model arranges adjustment components at the outer ends of both sides of the support frame. When placed, the third adjustment screw can be rotated to enable the support frame to move up and down in the adjustment frame according to needs. During the rotation, the bottom end can be driven by the nested shaft connected by rotation at the bottom end to drive the support bottom plate to move up and down along the adjustment box, thereby adjusting the upper and lower heights of the support points on both sides of the support frame, so that the support frame can be placed horizontally when used in different areas, ensuring that the rails can be kept on the same horizontal line when welding, thereby improving the welding quality of the rails, and being suitable for use in different areas, effectively reducing the limitations during use and improving its comprehensive use effect.

[0014] 2. The utility model embeds a laser level at the bottom end of one side of the inner cavity of the support frame. The laser level can emit three groups of mutually perpendicular laser beams when in use, which are compared with the frame edge of the support frame to detect the verticality of the support frame when it is placed, so as to quickly determine whether the support frame is placed vertically, thereby facilitating maintenance personnel to make quick adjustments to ensure the fixing effect when welding the rails. At the same time, the anti-slip pad arranged at the bottom end of the support base plate can improve the anti-slip property of the support base plate when supporting, ensure the stability of the support, further improve the stability of the rails when welding, and thus improve the welding quality.
