An arresting cable device for a trackless rubber-tyred vehicle stall protection system

Abstract

The invention discloses a stall protection system arrester wire device for a trackless rubber-tired vehicle. The stall protection system arrester wire device comprises a steel wire rope, guide wheels, tensioning devices and power absorbers. Mandrels of the guide wheels are each of a vertical structure with the fixed lower ends and the suspended upper ends. The two tensioning devices are correspondingly arranged on the two sides of a roadway in the distribution direction of a second part respectively and used for lifting and tensioning the steel wire rope upwards through the tensioning devices on the corresponding sides after the steel wire rope is wound around the guide wheels on the corresponding sides. The two power absorbers are arranged at the tail ends, distributed at the second part, of the two sides of the roadway respectively. Correspondingly, the steel wire rope is connected with the power absorbers through the tensioning devices. By the adoption of the stall protection system arrester wire device, reliable blocking can be provided for the out-of-control situation of the trackless rubber-tired vehicle.

Description

technical field [0001] The invention relates to an arresting cable device for a stall protection system of a trackless rubber-tyred vehicle. Background technique [0002] Chinese patent document CN103786694A first proposed a speed runaway protection system for trackless rubber-tyred vehicles using a tail hook. Its blocking rope (wire rope) passes through a simple support device to cross the roadway. During use, it is difficult to control the tension of the blocking rope and block the setting. In order to satisfy the blocking of the trackless rubber-tyred vehicle, the tail hook of the trackless rubber-tyred vehicle needs to be accurately hooked to the preset blocking rope. [0003] Restricted by the structure of the tail hook itself, for example, the end of the hook body has a certain profile size, and the tail hook may rebound to a certain extent when it falls and touches the ground. If the blocking rope is dragged on the ground, the tail hook may not be able to hook to the ...

[0002] Chinese patent document CN103786694A firstly proposed a speed out-of-control protection system for trackless rubber-tyred vehicles using a tail hook. Its blocking rope (wire rope) passes through a simple support device to cross the roadway. During use, it is difficult to control the tension of the blocking rope and block the setting.

[0010] Chinese patent document CN103786694A discloses a speed out-of-control protection system for trackless rubber-tyred vehicles, which prevents the rope from passing through a simple support device and a horizontal roadway. If the wheel supports the arresting rope, in the arresting state, the steel wire rope cannot escape from the guide wheel, and the huge impact force will directly damage the guide wheel and cannot be reused.
