Two-stage steering support carrying vehicle

Abstract

The invention discloses a two-stage steering support carrying vehicle. A vehicle head part comprises a cab body and a vehicle head case which are fixedly connected; two front wheels are mounted at the bottoms of the cab body and the headstock case; the hinging part comprises a mounting block, a connecting frame, a steering hydraulic cylinder, a hinging frame and a rear connecting plate; two middle wheels are mounted on the two sides of the bottom of the connecting frame; the two rear frames are detachably connected with the two supporting frames symmetrically arranged at the rear end of the rear connecting plate respectively. The fastening mechanism is connected with the support frame and the rear frame; two hoisting mechanisms are sequentially fixed on the top surface of the rear frame; and rear wheels are mounted at the bottoms of the two rear frames. According to the support carrying vehicle, two-stage hinge joint is achieved through the hinge joint part, steering is controlled through the steering hydraulic cylinder, the turning angle can be controlled to be minimum, turning is more flexible, rotation of the rear frame and the hinge joint frame can be achieved on a bumpy road due to the arrangement of the hinge joint frame, breakage caused by rigid connection is prevented, and the use effect is better.

Description

technical field [0001] The invention relates to the technical field of industrial and mining vehicles, and more specifically relates to a two-stage steering support truck. Background technique [0002] With the rapid development of my country's economy and the further extension of the integration of coal mine resources, the degree of mechanization and modernization of large coal mines in my country is getting higher and higher. And other mining equipment is developing towards large-scale and mechanized direction, and at the same time, the mining face is also further lengthened and enlarged. The support truck is an important equipment for the hydraulic support handling in coal mines. It can move the hydraulic support from the original continuous mining face to the new continuous mining face or the ground in a short period of time. The coal mine mainly uses diesel engine support for handling. car. [0003] At present, the hydraulic support trucks developed and produced in Chi...

AI Technical Summary

Problems solved by technology

[0003] At present, the hydraulic support trucks developed and produced in China can basically adapt to the working conditions of domestic coal mines, but there are still many problems in the use process: such as the space in the mine is relatively narrow, the road may be uneven, due to the size of the support truck Larger, so the corner angle is not easy to control when steering, which affects driving

At the same time, although the existing support truck can complete the work of carrying the support, there are still problems that need to be improved in various parts of the structure, such as the driver's cab, chassis, rear frame and hoisting structure, and there is great room for improvement.
