Tunnel gangue filling machine

Abstract

A roadway gangue filling machine for tunneling filling roadway mining method, which consists of a projecting belt part (1), a rotary table (3), a material feeding and conveying part (5), an underframe assembly (4), and a crawler walking part ( 2), composed of hydraulic system and electric control system. The frame of the projecting belt part has a hydraulically controlled telescopic mechanism and a gangue leveling device; the feeding and conveying part is composed of a leveling mechanism, a deflection adjustment mechanism and an inclination adjustment mechanism; the crawler walking part is driven by a hydraulic motor; the hydraulic system has an on-board hydraulic pump station . The function of free expansion and retraction of the ejection belt and flattening of gangue improves the filling efficiency and quality; the function of leveling, deviation adjustment and inclination adjustment of the feeding and conveying part prevents the belt from deviation and is easy to adjust; the hydraulic travel part has large traction, flexibility and grounding The specific pressure is small; the onboard hydraulic pump station completes the hydraulic system, which integrates electromechanical and hydraulic functions such as casting, feeding, walking, and operation, and the operation is safe, convenient and flexible; the onboard PLC electronic control system has multiple functions and complete protection. It is suitable for "three-down" coal mining in mines containing explosive gas and coal dust.

Description

technical field [0001] The invention relates to coal mine roadway gangue filling equipment, in particular to a roadway gangue filling machine which is mainly used for "three-down" coal mining in coal mines, and is used for coal mining by a tunneling-type filling roadway mining method. Background technique [0002] "Three-down" coal mining refers to coal mining under special geological and mining technical conditions such as buildings, water bodies, railways, and shaft coal pillars, which require special mining technologies. The roadway gangue filling machine is compatible with the "three-down" coal pressing method of tunneling filling roadway mining. This method not only solves the problem of coal resource recovery, but also solves surface subsidence and improves comprehensive economic benefits. The filling material is coal gangue, ground industrial waste, etc., which can realize that the gangue does not go up the well, and the ground does not build gangue hills, effectivel...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the shortcomings of the existing roadway gangue filling machine with simple structure, simple function and low performance, the present invention provides a roadway gangue filling machine. The projecting belt part not only has the functions of lifting and turning, but also has the functions of stretching and gangue bulldozing. Improve filling efficiency and quality; the feeding and conveying part has multiple functions of leveling, deflection and inclination adjustment, which can effectively prevent belt deviation; the track running part has good performance; the hydraulic system and electric control system have perfect functions, good performance and convenient operation
