An Embracing Mine Hoist Inspection Robot

Abstract

The invention discloses a holding type mine hoist inspection robot. The whole holding type mine hoist inspection robot is divided into an upper mechanical arm part and a lower mechanism arm part which are same in structure, wherein the two mechanical arm parts are connected with each other via a crank block mechanism and a sliding rod-sliding block mechanism; the two mechanical arm parts alternately hold a hoist stand column; meanwhile, due to combination of the crank block mechanism and the sliding rod-sliding block mechanism, the two mechanical arm parts alternately rise, so that the whole movement of the robot is implemented. The mechanical arm parts are used for connecting various joints in series via a steel wire rope; the various joints are connected with one another via a spring; the steel wire rope is driven to tighten and loosen via a hoisting motor; the opening and closing actions of mechanical claws are controlled under control of a restoring force of the spring; the holding type mine hoist inspection robot is simple and light in structure, flexible in actions and strong in holding force; the power requirement of the motor can be effectively reduced; the damage to the sprayed paint or protection layers of the hoist cable rope or the steel surface can be avoided.

Description

technical field [0001] The invention relates to a robot mechanism, in particular to a hug-type mine hoist inspection robot suitable for detection and maintenance of a coal mine hoist. Background technique [0002] Mining hoists are mainly used for dispatching mine cars and other auxiliary traction in mines, and can also be used for hauling, lifting or other auxiliary handling in coal mines, metallurgical mines, construction sites, etc., but they cannot be used for manned use. [0003] However, the detection and maintenance methods of mining hoists are relatively backward at present. Generally, winches or other lifting equipment are used to install manned platforms for manual inspection, which will increase manual risks. Climbing robots that have emerged in recent years generally use electromagnetically driven friction wheels to hold down. The robot climbs continuously, or uses pneumatic components to tighten creeping climbs, or uses claws to grasp bridge construction to achi...

Problems solved by technology

[0003] However, the inspection and maintenance methods of mining hoists are relatively backward at present. Generally, hoists or other lifting equipment are used to install manned platforms for manual inspection, which will increase manual risks.

Climbing robots that have emerged in recent years generally use electromagnetically driven friction wheels to hold down. The robot climbs continuously, or uses pneumatic components to tighten creeping climbs, or uses claws to grasp bridge construction to achieve continuous climbing, and then uses the inspection and painting equipment it carries to inspect the bridge. And maintenance, and these pressing or grasping fixing methods are not suitable for the inspection of the hoist, no matter the above-mentioned fixing methods, it will definitely damage the paint or protective layer of the hoist rope or the surface of the steel

Moreover, these robots have the disadvantages of heavy weight, inflexible activities, and high energy consumption.

Therefore, such robots have not been widely used in inspection and maintenance of hoists
