Abstract

The invention provides a crawling ladder for maintenance. The crawling ladder comprises a first longitudinal beam, a second longitudinal beam and a plurality of crossbeams, wherein at least one crossbeam is a safety protecting beam, each safety protecting beam comprises a safety transverse rod, a transverse rod sleeve sleeving the safety transverse rod, a support and a sensor, one end of the support is connected with the first longitudinal beam, the first end of the safety transverse rod is rotatably connected with the other end of the support through a rotary shaft, a retaining block in slide fit with the inner wall of the transverse rod sleeve is arranged on the outer surface of the second end of the safety transverse rod, an elastic telescopic part is arranged between the retaining block and the bottom plate of the transverse rod sleeve, a mounting hole is formed in the second longitudinal beam, the sensor is arranged at the mounting hole, a mounting shaft is arranged on one side, away from the retaining block, of the bottom plate, and the mounting shaft penetrates the mounting hole to be abutted against the telescopic probe of the sensor. The crawling ladder for maintenance has the advantages that maintenance staff can be well protected and possibility of safety accidents is lowered greatly.

Description

technical field [0001] The invention relates to the technical field of a climbing device for large-scale equipment maintenance, in particular to a maintenance ladder. Background technique [0002] Many large-scale equipment in the automobile production workshop are usually equipped with maintenance ladders to facilitate maintenance personnel to climb up to carry out operations. For example, for large-tonnage mechanical presses, maintenance personnel need to climb to the top beam of the maintenance ladder to perform maintenance operations. Since the ground personnel cannot see the figure of the maintenance personnel at this time, it is easier to start the equipment at will and cause a safety accident. [0003] In the prior art, the maintenance personnel are generally required to hang a safety warning sign at the lower entrance of the maintenance ladder before the climbing operation, and the ground personnel need to confirm whether the safety warning sign is hung at the lower ...
