Description

Technical Field

[0001] The utility model relates to the technical field of railway tracks, in particular to a railway track anti-climbing device. Background Art

[0002] When the train is moving, the wheels and the track interact with each other, generating a longitudinal force on the rails, causing the rails to move longitudinally, and sometimes even driving the sleepers to move together. This longitudinal movement phenomenon is called creeping in the industry. Therefore, railway companies must take effective measures to prevent creeping. The usual practice is to use anti-climbing devices to prevent line creeping. Publication (Announcement) No.: CN215051650U discloses an anti-loosening type railway track anti-climbing device, including a first anti-climbing device body, a first connecting block is provided at the bottom of the first anti-climbing device body, a first support plate is provided at the bottom end of one side of the first connecting block, a second anti-climbing device body is provided at one side of the first anti-climbing device body, a second connecting block is provided at the bottom of the second anti-climbing device body, a second supporting plate is provided at the bottom end of one side of the second connecting block, and ground nails are provided in the middle of the upper and lower ends of the first supporting plate and the second supporting plate, a slide groove is provided on one side of the front end of the first connecting block, a slider is provided inside the slide groove, a limiting groove is provided on the back of the slider, and a sealing groove is provided in the middle of one side of the second connecting block. The utility model discloses an anti-loosening type railway track anti-climbing device, which makes the fixing rod not easy to loosen, improves the safety of use, and is not inconvenient to disassemble due to rust, so that disassembly and installation are convenient.

[0003] The above-mentioned prior art solution has the following defects: the first anti-climbing device body is fixedly connected to the first connecting block, the second anti-climbing device body is fixedly connected to the second connecting block, the first anti-climbing device body is clamped to the bottom end of one side of the rail, and the second anti-climbing device body is clamped to the bottom end of the other side of the rail. Since there is no large pre-tightening force between the first connecting block and the second connecting block, there is no large friction force in the longitudinal direction between the rail and the first anti-climbing device body and the second anti-climbing device body respectively, which reduces the fixing effect of the anti-climbing device on the rail in the longitudinal direction, that is, reduces the use effect of the anti-climbing device. Utility Model Content

[0004] The technical problem that the utility model mainly solves is to provide a railway track anti-climber, in which a linear drive assembly drives the left V-shaped anti-climber assembly on the movable support seat to move toward the right V-shaped anti-climber assembly, so that there is a large friction force in the longitudinal direction between the rail and the left V-shaped anti-climber assembly and the right V-shaped anti-climber assembly, respectively, thereby enhancing the fixing effect of the anti-climber on the rail in the longitudinal direction, that is, improving the use effect of the anti-climber.

[0005] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a railway track anti-climbing device, comprising: a fixed plate, one end of the upper plane of the fixed plate is connected to a fixed support seat, and the other end is provided with a dovetail groove, a slider adapted thereto is slidably connected in the dovetail groove, the upper plane of the slider is connected to a mobile support seat, the upper plane of the mobile support seat is connected to a left V-shaped anti-climbing device assembly, and the upper plane of the fixed support seat is connected to a right V-shaped anti-climbing device assembly;

[0006] It also includes a linear drive assembly, which is suitable for driving the movable support seat to move horizontally toward the fixed support seat.

[0007] By adopting the above technical scheme, during installation, the fixing plate is placed under the rail, the right V-shaped anti-climber assembly is clamped to the bottom end of one side of the rail, and then the slider is slid in the dovetail groove, and the slider drives the left V-shaped anti-climber assembly to be clamped to the bottom end of the other side of the rail, and the linear drive assembly is operated to drive the slider to move toward the right V-shaped anti-climber assembly, so that there is a large pre-tightening force between the left V-shaped anti-climber assembly and the rail, and there is a large pre-tightening force between the right V-shaped anti-climber assembly and the rail, that is, there is a large friction force in the longitudinal direction between the rail and the left V-shaped anti-climber assembly and the right V-shaped anti-climber assembly, respectively, which enhances the fixing effect of the anti-climber on the rail in the longitudinal direction, that is, improves the use effect of the anti-climber, and next, the fixing plate is fixed to the foundation, so that the iron block is relatively fixed to the foundation.

[0011] By adopting the above technical solution, when the linear drive assembly drives the left V-shaped anti-climber assembly on the mobile support seat to squeeze the rail, due to the driving of the reverse force, several right triangular columns in the right V-shaped seat are tightly connected to the bottom end of the rail, thereby increasing the static friction between the right V-shaped anti-climber assembly and the rail in the longitudinal direction.

[0012] In a preferred example, the utility model can be further configured as follows: the linear drive assembly includes a circular hole arranged on a fixed support seat and a threaded hole arranged on a movable support seat, the threaded hole and the circular hole are concentrically arranged, a locking bolt is arranged in the circular hole, the end of the locking bolt is threadedly connected to the threaded hole, a locking nut is spirally connected to the locking bolt, and the locking nut is in contact with the left V-shaped anti-climbing device assembly.

[0013] By adopting the above technical solution, since the locking bolt and the threaded hole are threadedly connected, rotating the locking bolt drives the movable support seat to move toward the fixed support seat, thereby driving the left V-shaped anti-climbing device assembly to be tightly connected to the rail, and also drives the right V-shaped anti-climbing device assembly to be tightly connected to the rail. When the rail is tightly connected to the left V-shaped anti-climbing device assembly and the right V-shaped anti-climbing device assembly respectively, the anti-loosening nut is spirally connected to the locking bolt and fits tightly with the left V-shaped anti-climbing device assembly to achieve the purpose of preventing loosening.

[0014] In a preferred example, the utility model can be further configured as follows: four corners of the fixing plate are respectively provided with waist-shaped holes, anchor bolts are passed through the waist-shaped holes, and nuts are spirally connected to the upper ends of the anchor bolts.

[0018] In summary, the present invention includes at least one of the following beneficial technical effects:

[0019] The operation of the linear drive assembly drives several triangular columns in the left V-shaped anti-climber assembly to squeeze the rails.
