Overhaul climbing frame based on crane

Abstract

The invention discloses an overhaul climbing frame based on a crane. The overhaul climbing frame comprises a crane rack and a safety harness, wherein a climbing ladder is fixedly connected to the crane rack, a slide is slidably mounted at the upper end of the climbing ladder, the upper end of the slide is slidably connected with the crane rack, and an extending base is fixedly connected to one side of the slide; a buffer mechanism is fixedly arranged on the extending base and comprises a T-shaped rod and a pressure spring, the T-shaped rod is fixedly connected with the extending base through the pressure spring, and the tail end of the T-shaped rod is positioned in an open hole in the extending base; and a safety belt is fixedly connected to the tail end of the T-shaped rod, a positioningplate is slidably mounted on the safety belt, a plurality of threaded holes are formed in the positioning plate, and a plurality of positioning holes are formed in the safety belt. According to the overhaul climbing frame, the length of the safety belt can be adjusted, meanwhile, the safety belt is matched with the T-shaped rod and the spring to reduce stress borne by a user during falling, the safety belt can transversely move on the rack, and overhaul work of the user is more convenient.

Description

technical field [0001] The invention belongs to the technical field of crane maintenance frame, in particular to a crane-based maintenance climbing frame. Background technique [0002] A crane refers to a multi-action hoisting machine that vertically lifts and horizontally transports heavy objects within a certain range, also known as cranes, aerial cranes, cranes, and bridge cranes. Lifting equipment, because its two ends are located on tall cement columns or metal supports, it is shaped like a bridge, and the bridge frame of the bridge crane runs longitudinally along the tracks laid on the elevated sides on both sides, which can make full use of the space under the bridge frame for hoisting The material is not hindered by the ground equipment. It is the most widely used and the largest number of lifting machinery. The maintenance frame is for the later maintenance personnel to conveniently climb to repair, disassemble and install the parts on the crane. [0003] There are...

AI Technical Summary

Problems solved by technology

[0003] There are certain disadvantages in the use of the existing crane overhaul stand. The overhaul stand is fixed and cannot be adjusted according to the actual component overhaul position, and it does not have a tool box that can follow the movement, which is inconvenient for parts maintenance, and the seat belt does not have the effect of adjustable cushioning, there are certain potential safety hazards
