Vertical ladder crawling device

Abstract

The invention discloses a vertical ladder crawling device which comprises a supporting frame. Rolling wheels capable of vertically sliding along a climbing ladder are mounted on the inner side face of the supporting frame, a riding device is mounted at the lower portion of the supporting frame, shake preventing devices driving the rolling wheels to slide on a track are mounted on the supporting frame, a lifting frame which upwards extends and is in power connection with a lifting appliance is connected to the supporting frame in a sliding mode, a base is arranged on the lifting frame, a tractive compression spring is arranged between the upper surface of the base and the supporting frame, an insurance hook claw is connected to the lifting frame and comprises a lower-portion crank arm section and an upper-portion hook claw section inwards extending out and corresponding to a vertical ladder cross beam, the middle of the crank arm section is hinged to the lifting frame through a hinge shaft, and an elastic driving device driving the crank arm section to turn over around the hinge shaft is mounted between the crank arm section and the supporting frame. The vertical ladder crawling device can carry people or heavy objects and slide along the climbing ladder and has the advantages of being simple in structure, safe in operation and reliable.

Description

technical field [0001] The invention relates to a vertical ladder crawling device. Background technique [0002] Climbing ladders are installed in pipe wells, the outside of building walls, and wind power generation equipment. The climbing ladders are installed vertically along the wall. If the height of the above-mentioned climbing ladders is high, it is difficult for the operator to carry tools when carrying tools to work on the heights. Crawling is slow, time-consuming and labor-intensive, and has potential safety hazards. [0003] For example, when it is necessary to perform maintenance for the top facilities of the wind power generation equipment, personnel need to carry tools to crawl along the climbing ladder in the wind power generator, and at the same time need to carry a safety buckle. After crawling a certain distance, the safety buckle needs to be installed on the On the crawling ladder, the crawling speed is slow and it is very time-consuming and laborious. The...

[0002] Climbing ladders are installed in pipe wells, the outside of building walls, and wind power generation equipment, and the climbing ladders are installed vertically along the wall. If the height of the above-mentioned climbing ladders is high, it is difficult for the operator to carry tools when people need to carry tools for climbing operations. Crawling, crawling is slow, time-consuming and labor-intensive, and has potential safety hazards

[0003] For example, when it is necessary to perform maintenance for the top facilities of wind power generation equipment, personnel need to carry tools to crawl along the climbing ladder in the wind power generator, and at the same time need to carry a safety buckle. After crawling a certain distance, the safety buckle needs to be installed on On the crawling ladder, the crawling speed is slow and very time-consuming and laborious. The existing equipment cannot carry people to crawl safely along the above-mentioned crawling ladder. If the lifting device and the hanging basket are used alone, it is easy to cause instability such as shaking, and the safety factor is low.
