Description

Technical Field

[0001] The utility model relates to the technical field of rail circuit clamps, in particular to a rail quick connection line clamp. Background Art

[0002] Track circuit is a circuit that uses rails as a conductive path. It can automatically and continuously detect whether a section of rail is occupied by a train and is used to control the railway's signaling devices or switch devices to ensure driving safety. In certain situations, it is necessary to connect two rails with wires to achieve the effect of short-circuiting the two rails. Short-circuit wiring helps to maintain the balance of traction current in the two rails, and also has the effect of preventing signals from being mistakenly transmitted to track sections that should not be reached.

[0003] In the traditional short-circuit connection of two rails, the bottom of the rail needs to be deoxidized first, and then the conductor is connected to the screws on the electrical insulation section of the rail. Finally, the screws are tightened with a wrench to fix the conductor to the bottom of the rail, thus completing the short-circuit connection of the two rails.

[0004] The above method has the problem of wasting a lot of time in removing the oxide layer at the bottom of the rail, and also has the problem of low work efficiency due to manual use of a wrench to tighten the screws; therefore, it does not meet the existing needs, and a rail quick connection line clamp is proposed.

[0007] Preferably, a clamping jaw is formed between the movable jaw and the fixed jaw, and the lower end of the rail body is located inside the clamping jaw.

[0008] Preferably, the two oppositely disposed side panels are installed on both sides of the top panel, and the two oppositely disposed connecting panels are installed on both sides of the bottom panel.

[0013] 1. The utility model installs a movable clamp and a fixed clamp inside the clamp, and a clamping jaw is formed between the movable clamp and the fixed clamp. The lower end of the rail body is located inside the clamping jaw. The handle is pressed to drive the movable clamp to move forward and downward at the same time. At this time, the distance between the movable clamp and the fixed clamp is reduced, and the lower end of the rail body is clamped. When it is necessary to short-circuit the two rails, the lower ends of the two rails are clamped respectively with two clamps, and then the wires are passed through the wiring grooves of the two clamps respectively to connect the two clamps, thereby completing the short-circuit wiring of the two rails, simplifying the steps of short-circuit wiring and improving work efficiency.

[0014] 2.
