Catenary detection device

Abstract

The invention discloses a catenary detection device, which relates to the technical field of catenary detection. The catenary detection device comprises: a disassembly mechanism, which includes: an upper wheel; an upper wheel connecting arm connected with the upper wheel; a lower wheel; The lower wheel tensioning mechanism connected to the lower wheel; the column, the lower wheel tensioning mechanism is set on the column, and the upper wheel connecting arm is connected with the column through a shaft; the locking mechanism, which can be connected with the upper wheel connecting arm Transmission so that the upper wheel link has two positions: in the first position, the upper wheel link rotates to the upper wheel close to the lower wheel tensioning mechanism; in the second position, the upper wheel link rotates to the upper wheel away from Lower wheel tensioning mechanism, so that the gap between the upper wheel and the lower wheel enables the dismounting mechanism to be installed on or removed from the bus bar; the connecting frame connected with the column; the linkage mechanism installed on the connecting frame ,and many more. The application enables operators to quickly disassemble and assemble the movable carrier through fewer steps on the ground.

Description

technical field [0001] The invention relates to the technical field of catenary detection, in particular to a catenary detection device. Background technique [0002] The Π-type overhead rigid catenary has become the main overhead catenary form of urban rail subway lines in my country because of its compact and simple structure, safety and reliability, and high maintainability. Provide energy for vehicle operation. Due to the poor elasticity of the rigid suspension, and with the continuous increase of operating speed and induced current, the requirements for the technical status of the catenary are gradually increasing. In order to ensure the healthy operation of the rigid catenary, the operation and maintenance unit regularly inspects and analyzes the entire line of catenary, discovers equipment abnormalities in time and organizes maintenance to ensure transportation safety and healthy and reasonable operation and maintenance of the pantograph-catenary system. my country's...

Problems solved by technology

When it is necessary to disassemble the movable carrier from the busbar, the current mainstream solution is an independent disassembly structure designed for each wheel set. This device requires the operator to use a ladder truck to perform disassembly and assembly operations on each wheel set at high altitude. In order to complete the disassembly and assembly of the movable carrier, it has the disadvantages of high cost of use and cumbersome operation, and does not have the function of performing disassembly and assembly operations on the ground
