Multi-arm multi-drill drilling-loading-anchoring all-in-one machine with telescopic structure

Abstract

The invention discloses a multi-arm multi-drill drilling-loading-anchoring all-in-one machine with a telescopic structure. The all-in-one machine comprises a frame, a conveying channel, an excavatingwork arm, crawler walking mechanisms, an electrical system and a hydraulic system, wherein front roof bolters and rear roof bolters are arranged at the front part(s) and rear part(s) of one side or two sides of the excavating work arm respectively; drill arm mechanisms are arranged on the outer sides of the front roof bolters; the conveying channel is located in the middle of the rear end of the frame; telescopic platforms are arranged on the frame and on two sides of the conveying channel respectively; extension platforms are connected with a translation oil cylinder and a support arm translation oil cylinder via drill arm connection bases; the translation oil cylinder and the support arm translation oil cylinder are connected with a telescopic arm, and connected with a swing oil cylindervia a swing oil cylinder base; the swing oil cylinder is connected with sliding frame propelling beams; telescopic platforms comprise fixed platforms and extension platforms which are connected withthe fixed platforms and are telescopic. According to the all-in-one machine, the operation range is wide, full-face excavating, loading and drilling of shot holes and anchor rod and anchor cable holescan be achieved, front and rear drill arms can operate synchronously, and the novel drilling-loading-anchoring all-in-one machine achieves rapid excavation of a stone drift.

Description

technical field [0001] The invention relates to an integrated drilling and anchoring machine for coal mines, in particular to a multi-arm and multi-drilling and anchoring integrated machine with a telescopic structure. Background technique [0002] At present, in coal mines, non-coal mines, railways, highways, hydropower and other departments of large-scale rock roadway excavation construction, the drilling and blasting method is generally used for roadway excavation. This construction method has the following disadvantages: 1) The required equipment is large: hydraulic drill Truck + bolter + excavator loader, or drilling-installation machine + bolter two equipment; 2) Low operating efficiency: During the construction process, due to the need to alternately replace equipment many times, the equipment needs to occupy the work site A lot of time; 3) High construction cost: more equipment means more personnel, and it is necessary to build caverns for parking equipment at certai...

[0002] At present, in coal mines, non-coal mines, railways, highways, hydropower and other departments of large-scale rock roadway excavation construction, the drilling and blasting method is generally used for roadway excavation. This construction method has the following disadvantages: 1) The required equipment is large: hydraulic drill Truck + bolter + excavator loader, or drilling-installation machine + bolter two equipment; 2) Low operating efficiency: During the construction process, due to the need to alternately replace equipment many times, the equipment needs to occupy the work site A lot of time; 3) High construction cost: more equipment means more personnel, and it is necessary to build caverns for parking equipment at certain distances in the roadway or make wrong lanes; 4) There are potential safety hazards: equipment in the roadway There are frequent crossings in and out of the alley, and each device is driven by a motor. The light in the alley is not good, there are many connecting cables, and there are many workers, so there are many potential safety hazards in equipment and personal safety. ;5) The drilling arm and excavating arm of the existing drilling-mounting integrated machine and drilling-mounting (anchor) integrated machine have a small operating range, and there is local interference during operation, which cannot realize full-section operations; The overall size of the all-in-one machine is relatively large, but it is inconvenient to disassemble, go into the mine, transport and assemble the large machine
