Problems solved by technology

"Although this utility model is easy to lift and can be installed on the vehicle to move along with the vehicle, it has certain flexibility and maneuverability, but it is still a scissor-type hydraulic lifting platform that is lifted up and operated. Its structural form is still It is fixed at the lower end and the working platform is at the upper part. It is only suitable for the maintenance and repair of high-altitude equipment after it is lifted. extremely limited range

Abstract

The invention is a kind of hydraulic lifting platform for inner lifting work which belongs to track communication engineering field, one end of the transverse hydraulic oil cylinder is hanged on the base, one end of the piston pole is hinged to the transverse sliding bracket, two sides of the transverse sliding bracket set a roller, the scissor type lifting mechanisms are hinged with the transverse sliding bracket and working platform on top and bottom, the two ends of the lifting hydraulic oil cylinder are hinged on the scissors type lifting mechanism, the hydraulic station is fixed on the base or the bottom plate of the vehicle or the inner floor of the car, which is connected to the transverse hydraulic oil cylinder and the lifting hydraulic oil cylinder through pipes, the base is set on the bottom plate of the magnetic suspension track checking car, the measuring sensor is fixed on the base or the transverse sliding bracket, the scissors type lifting mechanism and the working platform. The working platform and the scissor type lifting mechanism are folded up and moved transversely into the base of the car bottom plate, when in working, they extrudes out of the base. The structure of the invention is reasonable, the stabilization is good.

Description

technical field [0001] The invention relates to a hydraulic lifting operation platform for engineering maintenance and overhaul operations, in particular to a built-in hydraulic lifting platform for maintenance and overhaul operations of maglev track beams. It belongs to the field of rail transit engineering. Background technique [0002] At present, the vehicle-mounted hydraulic lifting platform or elevator used for maintenance and repair operations, as well as the vehicle-mounted scissor-type hydraulic lifting platform or elevator, are all operating platforms above the entire hydraulic lifting system, and are used for climbing operations or high-altitude operations after being raised. , it can be lowered after the work is completed or usually does not work; and the track engineering vehicle used for the inspection, traction, maintenance and overhaul of the special maglev track beam for the maglev high-speed train needs to be located on the outside of the car body. , The s...
