Movable device for high-speed rail maintenance

Abstract

The invention discloses a movable device for high-speed rail maintenance. The movable device comprises two supporting plates; two connecting columns and first connecting pieces are fixedly connected to the bottoms of the supporting plates; an adjusting assembly is connected between rotating rods on the two sides; fixing columns are fixedly connected to the upper ends of the supporting plates; driving assemblies connected to the lower sides of lead screws; lifting columns are in threaded connection with the upper sides of the lead screws; and a hoisting assembly is arranged between the liftingcolumns on the two sides. The device is driven by universal wheels to move, so that moving is convenient, and time and labor are saved; the universal wheels are folded through the adjusting assembly,the device is supported on the ground through footstands, the stability in the maintenance process is guaranteed, the fixing columns and the hoisting assembly are driven by the driving assemblies to ascend and descend, and the hoisting height of the hoisting assembly can be adjusted according to different heights of different parts, the flexibility is high, parts can be hoisted on hoisting hooks for hoisting and maintenance through the hoisting assembly, the stability of the parts during maintenance is improved through hoisting of the multiple hoisting hooks, the situations of rope breakage, part falling and the like caused by the single hoisting hook are prevented, and the use safety is high.

Description

technical field [0001] The invention relates to the technical field of high-speed rail maintenance auxiliary equipment, in particular to a mobile device for high-speed rail maintenance. Background technique [0002] High-speed railway, referred to as high-speed railway, refers to a railway system with high design standards and safe high-speed travel for trains. The historical development of world railways proves that high-speed railway is an inevitable trend of economic and social development. The high-speed rail train is a modern high-speed transportation tool, which is a concentrated expression of the top science and technology of the train, which can greatly increase the speed of train travel and thus improve the efficiency of train transportation. When a high-speed train component or a railway component fails, the component needs to be disassembled for maintenance and other operations, and hoisting equipment is required to lift the component for maintenance.

AI Technical Summary

Problems solved by technology

[0003] The existing high-speed rail maintenance device is inconvenient to use and requires staff to carry it, which is time-consuming and laborious, and has poor flexibility; Some high-speed rail maintenance devices have only one electric hoist and one hook to lift the components. Not only is the lifting of the components not stable enough, it is not conducive to the maintenance operations of the staff, but it is also easy to cause the suspension rope to break or the components to fall, and the use safety is poor. Prone to safety accidents, unable to meet people's needs
