An anti-tipping, fast-group catenary operation ladder truck

Abstract

An anti-tipping and quick-group catenary operation ladder truck, comprising: a base (5), a ladder body, and a working platform (10), the opposite sides of the ladder body are trapezoidal, and the base (5) is equipped with an anti-ladder truck rollover The locking mechanism is a push-type normally closed locking linkage mechanism, including: a push armrest (1) arranged on the base (5), and a connecting rod is connected to each side of the push armrest (1) The locking device (2), the chuck (231) of the connecting rod locking device (2) and the base (5) are kept engaged with the rail (3) by the action of the tension spring (25), and press down / Release the push handrail (1) so that the chuck (231) of the connecting rod locking device (2) disengages / engages with the rail (3); the base (5) and the working platform (10) are respectively combined with the ladder body , the ladder body is combined and connected by more than one segment, and the combined connection is equipped with a quick connector (6). Once the ladder car stops, it will be automatically locked to prevent rollover. It can be transported in sections and quickly installed and disassembled. Different heights need to be quickly assembled on site.

Description

technical field [0001] The invention relates to an electrified catenary project, in particular to an anti-overturning and fast-assembling catenary operation ladder truck used for installation and maintenance at high places of the catenary project. Background technique [0002] In the construction and maintenance of the electrified catenary, the ladder car is an indispensable and important tool for climbing operations. In the subway catenary project, the height of the ladder car used in the main line section is generally 3 meters, while on the crossing line, or in the large railway contact In network engineering, the height of the ladder car needs to be 3-5 meters. In order to facilitate manual handling, the ladder car is generally made of steel pipe materials as a whole. Due to the limitation of the rail gauge, the base of the ladder car on both sides vertically along the rail is narrow and the body is high. It is easy to cause the ladder car to roll over during use, causing...

AI Technical Summary

Problems solved by technology

Since the ladder car adopts an overall structure, the structure is relatively complicated, the cost is high, and the weight is relatively large. The technical problems of simple structure, small weight, and easy manual transportation have not yet been solved.

[0005] In the prior art, there has not been an ideal catenary work ladder truck with simple structure, small weight, convenient manual transportation, and can be increased to meet the needs of different working heights.
