Description

Technical Field

[0001] This utility model relates to the field of wire rope traction technology, specifically a broken wire rope protection device for zipline traction. Background Technology

[0002] Currently, the common anti-breakage device for the traction cable in ziplining is the wedge-shaped friction block. Its principle is to stop the high-speed moving trolley by relying on the sliding friction between the friction block and the steel wire rope. However, this will cause serious damage to the steel wire rope. Once the rope breaks, the load-bearing steel wire rope will be severely damaged and must be replaced, resulting in a significant loss. Furthermore, the friction force of the wedge-shaped friction block is insufficient to stop the vehicle in high-speed ziplining, thus failing to achieve the expected effect. Utility Model Content

The curved connecting rod is connected and hinged to a straight connecting rod fixed on a camshaft. An eccentric cam is fixed at the lower end of the camshaft, and a load-bearing cable passes between the two eccentric cams. When the traction cable breaks in the middle, the eccentric cam rotates under the action of the spring force and clamps the carrying cable, so that the high-speed trolley can stop in time to prevent slippage and avoid safety accidents.

[0019] When the device is operating normally, the traction steel wire rope drives the traction rod to overcome the resistance of the spring, causing the eccentric cam to open and loosen the load-bearing steel wire rope, so that the trolley device can run smoothly along the load-bearing steel wire rope. If the traction steel wire rope breaks, the traction rod, under the action of the spring, drives the eccentric cam to reset, causing the cam to quickly press against the load-bearing steel wire rope. Therefore, the trolley device is held tightly on the load-bearing steel wire rope to prevent the trolley from sliding down and causing a major accident.
