Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of railway maintenance equipment manufacturing, in particular to an overhead anti-electricity connection fixing gasket for railway lines. Background Art
[0002] In traditional overhead of existing lines, a rubber flat gasket is used to support the track and the steel cross beam to prevent electrical connection between the cross beam and the rail. However, after repeated rolling by heavy trains, the flat gasket is prone to loosen and shift, unable to ensure effective anti-electricity connection measures between the cross beam and the rail.
[0003] Another anti-electricity connection method is to inject glass glue insulation glue between the platen plates for insulation. The disadvantages of this method are: 1. The setting time of glass glue is long, it is easy to age in the natural environment, and it is easy to crack at the contact surface with the platen plate, resulting in electrical connection; 2. The operation is complex. When maintaining turnouts by railway maintenance workers, the glass glue is damaged and needs to be re-injected. Content of the Utility Model
[0004] The utility model provides an overhead anti-electricity connection fixing gasket for railway lines to solve the technical problems of poor effect and easy damage of the existing anti-electricity connection methods.
[0005] To solve the above problems, an overhead anti-electricity connection fixing gasket for railway lines provided by the utility model adopts the following technical scheme:
[0006] An overhead anti-electricity connection fixing gasket for railway lines includes a base plate. There are two first baffles arranged on the base plate at intervals along the extending direction of the track, and the distance between the two first baffles is adapted to the cross beam. There are also two second baffles arranged on the upper end surface of the base plate at intervals along the extending direction of the cross beam, and the distance between the two second baffles is adapted to the track. The base plate, the first baffles and the second baffles are all made of polypropylene rubber material.
[0007] The beneficial effects are as follows: When the overhead anti-electricity connection fixing gasket of the utility model is in use, first place the base plate on the cross beam, and at the same time make the two first baffles clamp the cross beam along the extending direction of the track to fix the base plate in the extending direction of the track; then cooperate the two second baffles with the track so that the two second baffles clamp the lower end of the track. When replacement is needed, only cut the base plate to remove it, then place a new base plate on the cross beam and push it under the track. When the overhead anti-electricity connection fixing gasket of the utility model is in use, it can clamp the track and the cross beam, and is not easy to age due to being made of polypropylene rubber material, and is convenient for replacement when damaged.
[0008] Furthermore, the first baffle is detachably connected to the lower end surface of the base plate.
[0009] Beneficial effects: Facilitate disassembly, installation and maintenance.
[0010] Further, two rows of first fixing holes are formed in the substrate, and the two rows of first fixing holes are arranged in one-to-one correspondence with two first baffles. Second fixing holes which are adapted to and coaxial with the corresponding first fixing holes are formed in the first baffles. The first fixing holes and the second fixing holes are both threaded holes, and bolts are arranged in the first fixing holes and the corresponding second fixing holes to connect the first baffles and the substrate together.
[0011] Beneficial effects: The structure is simple and the operation is convenient.
[0012] Further, the second baffle is an L-shaped plate including a horizontal section and a vertical section, and the horizontal sections of the two second baffles are arranged oppositely. The horizontal section, the vertical section of the second baffle and the substrate form a card slot for clamping the track.
[0013] Beneficial effects: Improve the stability of the substrate and prevent the track from contacting the cross beam due to the movement of the substrate.
[0014] Further, the lower end surfaces of the two first baffles are arranged obliquely downward from the direction where the two first baffles face each other to the direction where the two first baffles face away from each other.
[0015] Beneficial effects: Facilitate inserting the two first baffles to both sides of the cross beam. Description of the Drawings
