Multifunctional operation ladder trolley

Abstract

The invention provides a multifunctional operation ladder trolley, and belongs to the technical field of railway track ladder trolleys. The multifunctional operation ladder trolley comprises a workingplatform, a supporting frame, a chassis, end part anti-tipping devices arranged at two ends of the chassis, and braking and lateral anti-tipping devices arranged at two sides of the chassis. According to the multifunctional operation ladder trolley, braking and tipping prevention of the ladder trolley are achieved, the safety of the ladder trolley is greatly improved, and the ladder trolley can be used at various crossed rails, turnouts and other positions; the supporting frame comprises stretchable ladders, the extending height of the ladder trolley can be adjusted according to the individual height of an operator, the adjusting mode is convenient and fast, and safety is good; and for the working platform, the relative positions of a fixed platform and a sliding platform can be adjustedaccording to the actual operation range and are fixed through positioning pins, and enough working space can be provided.

Description

technical field [0001] The invention belongs to the technical field of railway track ladder cars, and specifically discloses a multifunctional working ladder car. Background technique [0002] The ladder car is a tool to assist the staff to complete high-altitude operations. There are many kinds of ladder cars, one of which can walk on the railway track and complete the maintenance work above the tunnel. There are following problems in existing work ladder car: [0003] 1. Lack of anti-tipping device. In the position where there is no cross rail, the working ladder car on the track can be locked through a simple structure, but for the turnout and the intersection of multiple rails, the existing locking cannot be used. In actual operation, the more the position above the rail crossing, the larger the working surface, the more work, the more it is necessary to ensure the safety of the work; [0004] 2. The height of the working ladder car cannot be adjusted. The individual h...

AI Technical Summary

Problems solved by technology

[0003] 1. Lack of anti-tipping device. In the position where there is no cross rail, the working ladder car on the track can be locked through a simple structure, but for the turnout and the intersection of multiple rails, the existing locking cannot be used. In actual operation, the more the position above the rail crossing, the larger the working surface, the more work, the more it is necessary to ensure the safety of the work;

[0004] 2. The height of the working ladder car cannot be adjusted. The individual heights of the workers are different, and the heights of the construction positions are different. When the workers climb up the ladder car, they often feel that the height is inappropriate, but they cannot be adjusted;

[0005] 3. The working range of the working bucket of the working ladder truck is very small, limited to the working bucket, but during construction, it is often necessary to exceed the moving range of the working bucket. The traditional method is to use wooden boards to widen the moving range of the operator, which has great Security risks;

[0006] 4. The operation ladder is heavy, inconvenient to transport, and takes a long time to assemble and disassemble. The "skylight period" of the operation during construction is very short, or there must be problems of cross-construction and mutual influence during construction. When the railway locomotive performs transportation operations , it is necessary to move the work ladder truck express to facilitate the passage of the transport vehicle
