Wheeled mobile support unit

Abstract

The invention discloses a wheeled mobile support unit, and relates to mine mobile support equipment. The unit is used for temporary support of gob side entry retaining or work advance heading, and solves the problem that an existing mobile support equipment system is complicated and has poor adaptability. A wheel frame is added on the basis of a unit bracket, a pair of universal wheels are arranged in front of the wheel frame, and a pair of fixed wheels are arranged at the rear. The universal wheels and the fixed wheels cooperate with a sliding groove in a body of the wheel frame through a guide column, and a lifting jack fixed to an upper support frame vertically raises and lowers walking wheels; the body of the wheel frame and a support unit base are horizontally connected in the left and right directions through a push-pull jack, a walking wheel lifting state is based on the support unit to push the wheel frame, a walking wheel landing state pushes the support unit on the basis of the wheel frame, and the overall lateral movement is alternately achieved; during the long distance transportation, the walking wheels touch the ground and walk through external traction power. The unit adds the self-shifting function of a wheeled walking bracket and improves the system adaptability.

Description

technical field [0001] The invention relates to a mine mobile support equipment, in particular to a roadway temporary support wheel type movable support unit. Background technique [0002] With the increase of coal mining intensity and the harsh mining environment, the requirements for temporary support in the roadway including special techniques such as advance support of fully mechanized mining face and gob-side entry retention are getting higher and higher. The support strength of the traditional single support is low, intensive support requires a lot of manpower, and the danger is high; the temporary hydraulic support in the roadway solves the problem of support strength, but repeated support causes damage to the roof and anchor net system, making it impossible to adapt support requirements. It is a development trend to move conveniently in all directions and to support highly reliable support units without repeated support. For example, the patented monorail hoisting t...

AI Technical Summary

Problems solved by technology

The above schemes have problems such as complex system, high cost, efficiency and adaptability, which restrict the promotion and application

The wheeled walking device has high reliability, but it is difficult to realize the straight-line lateral movement in a narrow space with a fixed frame; it is urgent to develop a movable supporting unit that can move sideways in a short distance from left to right, and transfer long distances from front to back
