Multifunctional scaling ladder truck and working method

Abstract

The invention discloses a multifunctional scaling ladder truck and a working method.The multifunctional scaling ladder truck comprises a scaling ladder truck base, a rotary working platform, a scaling ladder set, an organ air bag channel and a scaling ladder transporting trolley, the scaling ladder set comprises a supporting scaling ladder and a movable scaling ladder, the supporting scaling ladder is sleeved with the movable scaling ladder, and the movable scaling ladder extends out of one end of the supporting scaling ladder; the supporting scaling ladder is of a V-shaped structure and is divided into a guide rail scaling ladder part and a counterweight scaling ladder part, the scaling ladder transportation trolley comprises a trolley underframe, an X-shaped connecting rod support and a trolley bearing cabin, and the organ air bag channel is of a convex structure and is laid between the supporting scaling ladder and the movable scaling ladder; the scaling ladder transportation trolley and the movable scaling ladder both adopt a traction rope driving mode, the speed is high, the efficiency is high, the lever effect generated in the working process of the scaling ladder transportation trolley is balanced through the design of the guide rail scaling ladder part and the balance weight scaling ladder part, and an air cushion scheme is automatically formed through the design of an organ air bag channel and a one-way door to provide buffering.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a multi-functional ladder truck and a working method. Background technique [0002] A ladder truck refers to a tool vehicle that can transport people, rescue materials, rescue trapped people, spray fire extinguishing agents, building materials, and working equipment to high altitudes. It is divided into two types: civil and fire fighting. The civil one is mainly used to help people transport equipment and working materials to high altitudes, and the firefighting one is used to help rescue trapped people on high floors. The ladder truck is mainly equipped with a telescopic ladder. In the construction of the project, the ladder is used as a passage for high-rise operations or deep well operations. The feeding truck travels on the ladder to achieve transportation operations at two heights. [0003] The ladder truck generally uses a hydraulic power telescopic ladder t...

AI Technical Summary

Problems solved by technology

[0006] Although the technical solution disclosed above solves some problems in a targeted manner, the lifting device composed of the hydraulic power part and the mechanical transmission part still adopts a hydraulic drive mode, and the mechanical transmission part with a hinged structure between the connecting rods is caused by a high degree of complexity. Low reliability and high requirements on the strength of the connecting rod. The aerial ladder vehicle with an extended platform has high requirements on the surrounding ground environment when deployed, requiring a large flat ground, and it is difficult to deploy on a narrow road. , the problem of the out-of-control transport trolley using the broken cable anti-skid device to act as a brake can only play a protective role. However, the personnel and materials in the transport trolley still need to reach the ground, and this process is difficult to solve

To sum up, it is necessary to develop a multifunctional aerial ladder vehicle to solve the problems of slow erection speed, operational stability of the aerial ladder vehicle and safety of the transport trolley
