Problems solved by technology

[0004] 1. When the general maintenance and inspection work equipment is in use, the station platform is not stable enough when it is raised, and it is easy to cause shaking, which leads to certain risks for the staff when working
[0005] 2. Since the bottom pulley cannot be retracted when the traditional maintenance and inspection work equipment is in use, the device is easy to move and it is not convenient for the staff to carry out inspection work
[0006] 3. Since the general maintenance and inspection work equipment is in use, there is no protective device and protective device on the station platform, which makes it easy for the staff to fall and cause injury when working on the station platform, which is inconvenient for users to use

Abstract

The invention discloses an operation tool for rail transit maintenance and inspection. The operation tool comprises a transmission box, the top of the transmission box is rotationally connected with a threaded rod, one end of the threaded rod penetrates through the outer wall of the transmission box, and the outer portion of the threaded rod is sleeved with a right-hand threaded block and a left-hand threaded block in a threaded manner; and connecting shells are fixedly mounted at the top of the right-hand thread block and the top of the left-hand thread block correspondingly, second movable shafts are fixedly mounted in the two connecting shells correspondingly, supporting rods are rotationally connected to the exteriors of the two second movable shafts correspondingly, a standing table is arranged at the top of the transmission box, and a clamping shell is fixedly mounted at the bottom of the standing table. Through cooperation of the supporting rods and the threaded rod, the standing table can be stably and rapidly lifted; through cooperation of a gear column and a telescopic column, a pulley can be stored in the transmission box, and therefore the bottom can be placed more stably when a worker works; and the worker can be prevented from falling down and falling off during working through the cooperation of an anti-falling plate and a hook plate.

Description

technical field [0001] The invention belongs to the technical field of track maintenance and inspection, and in particular relates to a work tool for rail transit maintenance and inspection. Background technique [0002] With the development of the times, rail transit such as subways in cities is becoming more and more developed. To ensure the stable and normal use of subway rail transit, it is generally necessary to regularly inspect and maintain the rails and the interior of urban subway tunnels. Maintenance and inspection work equipment to assist the staff to carry out inspections. [0003] However, traditional devices also have the following problems in use: [0004] 1. When the general maintenance and inspection work equipment is in use, the station platform is not stable enough when it is raised, and it is easy to cause shaking, which leads to certain risks for the staff when working. [0005] 2. Since the bottom pulley cannot be retracted when the traditional mainte...
