A crawler-type magnetic adsorption cable detection robot

Abstract

The invention discloses a crawler type magnetic adsorption cable detecting robot. The crawler type magnetic adsorption cable detecting robot comprises a framework, a V-shaped rubber crawler, a clutch, a falling speed limiting device and at least two V-shaped loading wheels, wherein the V-shaped rubber crawler is coated on the periphery of all the V-shaped loading wheels; magnetic adsorption units are packed in the V-shaped rubber crawler; one or more V-shaped loading wheels are driving wheels; the falling speed limiting device is connected with one of the V-shaped loading wheels through the clutch; the framework comprises machine frames which are symmetrically arranged on two sides of the V-shaped rubber crawler; and each of the machine frames adopts a two-section type structure. Through the adoption of the structure of the crawler type magnetic adsorption cable detecting robot disclosed by the invention, the structure is compact, the operation is simple and convenient, and the obstacle surmounting capacity is high; the derailing preventing capacity of the robot can be improved by the V-shaped rubber crawler; the magnetic adsorption units are packed in the V-shaped rubber crawler, so that the collision between the crawler and the surface of a pull cable can be buffered; besides, according to the radius of the loading wheels, the diameter of the magnetic adsorption units is designed, so that the phenomena of impacting generated when the crawler goes around the loading wheels can be avoided. In addition, the falling speed can be adjusted, and the crawler type magnetic adsorption cable detecting robot disclosed by the invention can adapt to the push cables in different inclinations.

Description

technical field [0001] The invention relates to a fault robot used in cable detection of large cable-stayed bridges, in particular to a crawler-type magnetic adsorption cable detection robot. Background technique [0002] Cable-stayed bridges are currently the most widely used bridges, relying on multiple cables to bear the load. Therefore, the cables are related to the safety of the entire bridge, and the cables must be regularly inspected and maintained. The detection of cables belongs to high-altitude operations, and this dangerous work can be completely replaced by robots. [0003] For the robot specially used for cable-stayed bridge detection, according to the actual needs, the following requirements must be met: (1) It can adapt to cables of different diameters, which can greatly reduce the development cost; (2) Since the cable-stayed bridge consists of multiple In order to reduce working time and personnel input, it is necessary to increase the working speed of the r...

Problems solved by technology

In addition, most of the existing safety recovery schemes are based on the friction plate speed limiter. The disadvantage of this recovery method is that it cannot adapt to cables with different inclinations. If the braking force is too small, the speed limit effect cannot be achieved. too big and it will freeze
