Special crawler chassis for raise boring machine

Abstract

The invention discloses a special crawler chassis for a raise boring machine. The special crawler chassis for the raise boring machine comprises a power unit assembly, a crawler assembly, a chassis rack and a supporting leg assembly, wherein the power unit assembly comprises a power unit underframe; the crawler assembly is connected with the chassis rack; the chassis rack is connected with the power unit underframe; the supporting leg assembly comprises four supporting legs; two of the four supporting legs are mounted in supporting leg oil cylinder mounting holes of the chassis rack; the other two supporting legs are mounted on the power unit underframe; the two supporting legs mounted on the chassis rack can be adjusted independently; the other two supporting legs mounted on the power unit underframe are adjusted synchronously; and bottoms of the four supporting legs are supported on the ground. The special crawler chassis for the raise boring machine is compact in structure, and therefore, autonomous movement and stable traveling of the raise boring machine are realized.

Description

technical field [0001] The invention belongs to the technical field of mining machinery, in particular to a special crawler chassis for a raise drilling machine. Background technique [0002] Most of the traditional raise drilling rigs use slipper shoe and rail-wheel chassis, which have no ability to move independently. They must be transported in cages from the top of the well to the underground construction site. When changing the construction site on the same underground track, external traction must be used. In the process of erecting and closing the machine, the chassis frame must be fixed with a rail clamp, and the rail clamp is used to provide a balance moment so that the main machine can be erected and closed smoothly without tipping over. Whether it is transportation up and down the well, on-site movement, and machine collection and stand-up, these two chassis are very cumbersome and require a lot of supporting facilities and manpower. [0003] In order to solve th...

Problems solved by technology

It realizes the walking of the patio drilling rig on the trackless road through the tires, but the tire-type walking mechanism has high requirements on the flatness and firmness of the ground, so as to avoid excessively deep wheel ruts, increase driving resistance and steering resistance, and affect the driving stability of the whole machine
