Automatic whole-section external rotor low-speed motor cutting rotation drum anchor driving machine

Abstract

The cylindrical excavating and anchoring machine as one mining apparatus consists of main frame, sliding frame, walking mechanism, hydraulic system, and spraying and dust eliminating system. The sliding frame embedded on the main frame can slide horizontally back and forth under the pushing mechanism, and the cutting part, top anchoring part and the loading part on the sliding mechanism operate simultaneously while the side supporting part on the main frame anchors the side parts. The present invention realizes sync cutting, loading and anchoring in high excavating speed and accurate positioning. In addition, the leading hole prospecting machine on the main frame may be used conveniently without need of moving.

Description

technical field [0001] The invention relates to an electromechanical integrated mining excavation equipment. Background technique [0002] The domestic coal and semi-coal rock roadheader is composed of a cutting part (the cutting motor is installed longitudinally on the working arm), a traveling part, a shipping part, a hydraulic system, an electric control system, and a spraying system. Its working principle is: when the cutting motor rotates, the cutting drum is driven to rotate through the reduction mechanism, and the rotating cutting drum swings left and right to cut and excavate. Its main disadvantages are: (1) When cutting and loading coal (rock), in addition to the left and right swings of the working arm, the fuselage also needs to swing left and right. Therefore, in addition to the scraper conveyor on the fuselage, there is also a It is necessary to set up a reloading belt conveyor to overlap with the belt conveyor in the back alley, and the shipping system is comp...

Problems solved by technology

Its main disadvantages are: (1) When cutting and loading coal (rock), in addition to the left and right swings of the working arm, the fuselage also needs to swing left and right. Therefore, in addition to the scraper conveyor on the fuselage, there is also a It is necessary to set up a reloading belt conveyor to overlap with the belt conveyor in the back alley, and the shipping system is complicated; (2) The cutting drum is small, and the cutting speed is slow when it swings left and right and up and down; (3) The excavation and top support, side The support cannot be operated synchronously. When it is necessary to anchor the roof and side of the roadway on the "wotou", it is necessary to stop the cutting of the roadheader before the staff can lift the drilling tools (roof bolter, coal electric drill, etc.) "Wotou", carry out anchor support, and after supporting a row, the drilling tool must be lifted out again, so that the fully mechanized excavator can work normally

Excavation and anchoring cannot be performed synchronously, resulting i...
