Precise positioning device for fast tunneling equipment in coal mine coal mining tunnel

Abstract

The invention provides a precise positioning device for fast tunneling equipment in a coal mine coal mining tunnel. The precise positioning device comprises a tunneling machine, a crushing machine, an anchor rod drill wagon, a stepping type self moving machine tail, a self moving force station and a rubber belt reversed loader, and is structurally characterized by also comprising nine node positioners, four wireless translation gateways, wireless base stations, positioning displays and positioning controllers, wherein the nine node positioners are respectively arranged on the tunneling machine, the crushing machine, the anchor rod drill wagon, the stepping type self moving machine tail, the self moving force station and the rubber belt reversed loader; the four wireless translation gateways are respectively arranged on the crushing machine, the anchor rod rill wagon, the stepping type self moving machine tail and the self moving power station; the wireless base stations, the positioning displays and the positioning controllers are arranged on the anchor rod drill wagon; and electromagnetic waves are mutually emitted between the node positioners arranged on two pieces of adjacent equipment so that space monitoring is carried out. The precise positioning device has the advantages that collision or falling accidents due to too short distance between the adjacent equipment can be effectively prevented; the positioning precision can reach 0.4m; and the positioning range is not smaller than 200m.

Description

technical field [0001] The invention relates to a positioning device for construction machinery, in particular to a precise positioning device for rapid excavation equipment in a coal mining roadway in a coal mine. Background technique [0002] The rapid excavation equipment in the coal mine roadway usually includes mobile equipment such as roadheaders, crushers, bolters, belt transfer machines, stepping self-moving tails and self-moving power stations. During the coal mining and excavation process in the roadway , there is a front-to-back movement relationship among roadheaders, crushers, rock bolters, belt transfer machines, stepping self-moving tails and self-moving power station equipment. During the movement of various related equipment, if adjacent equipment If the distance between them is too close, it will cause collision accidents between adjacent equipment; there is a vertical movement relationship between the tape transfer machine and the stepping self-moving tail...

AI Technical Summary

Problems solved by technology

The distance between the rapid tunneling equipment in the traditional monitoring coal mining roadway is manually observed by the operator. However, due to the large dust and short viewing distance during the tunneling in the coal mining roadway, it is difficult for the operator to accurately observe the distance between the equipment with the naked eye. Even if the operator issues a problem, it is very difficult to issue a timely alarm, which will easily lead to collision and fall-off accidents of the rapid excavation equipment in the coal mining roadway, affecting the production efficiency and safety of the coal mine
