Abstract

The invention relates to a coal mining excavating technology, and concretely relates to a suspension reversed loader bend excavating construction process. In coal mine digging, problems that safety production coefficient is increased during excavating, excavating efficiency is increased, and labor intensity is reduced at inflection point position can be solved. The process comprises the following steps: when a heading machine in a tunnel excavates to the inflection point position, when the tunnel turns off, three wire ropes are arranged between a tunnel top board and a crossing top board, while excavating, a tail of the reversed loader is suspended on the wire rope through a pulley and a steel wire lifting rope, a belt is arranged below the reversed loader, the reversed loader can move along the sliding of the wire rope by following with movement of a set; by increasing the bending angle of the reversed loader, position of a hoisting point on the wire rope is continuously adjusted, reversed loader position is suspended by three wire ropes, the whole reversed loader set turns off in the crossing position, and continuous coal output can be realized.

Description

Hanging elevating conveyor turns round tunneling construction process

Technical field

the present invention relates to a kind of coal mining piercing technique, be specially a kind of hanging elevating conveyor and turn round tunneling construction process.

Background technology

in coal mining construction, during tunnelling process, to Heng Chuan position or cut the corner position such as eye turn round construction time, general adopt development machine to pull elevating conveyor to turn round construction.As schematically shown in Figure 1, there is the machine of moving back when producing coal in this construction technology for its construction location and method, coal cutting, coaling, coal heaver's sequence time lengthening, drivage efficiency reduces; Elevating conveyor frequently drops from supporting part, and generator electrification, causes potential safety hazard; After work plane coal trickles down unit and elevating conveyor in a large number, during construction the 4 to 14 of especially turning round row, after almost all trickling down unit, artificial clear coal amount is very large.

Summary of the invention

the present invention, in order to solve in the digging of colliery, improves safety in production coefficient in the driving of corner position, improve drivage efficiency, reduce the problems such as worker labour intensity, provides a kind of hanging elevating conveyor and to turn round tunneling construction process.

technical scheme of the present invention, a kind of hanging elevating conveyor turns round tunneling construction process, when development machine tunnels corner position in tunnel, before tunnel preparation is turned round, 2 points are selected along roadway direction at back place, each point is made a call to two and is played cathead, connects, be fixed on by wire rope between two strands of anchor chains between two anchor poles with anchor chain; On back, select a point again, select a point in the top board of horizontal river, each point is made a call to two and is played cathead, connects, be fixed on by wire rope between two strands of anchor chains between two anchor poles with anchor chain; Select 2 points at horizontal Chuan Dingbanchu along roadway direction, each point is made a call to two and is played cathead, connects, be fixed on by wire rope between two strands of anchor chains between two anchor poles with anchor chain;

turn round driving time, by transfer conveyor tail by pulley and wire sling hanging wire rope on, under belt is layed in elevating conveyor, elevating conveyor just can follow the movement of unit along steel cable sliding; Along with development machine angle of turning round strengthens, constantly adjustment position on a steel cord, Heave Here, by three sections of wire rope hanging elevating conveyor positions, makes all to tunnel unit and turns round in horizontal river, and realizes producing coal continuously.

compared with prior art, hanging elevating conveyor of the present invention turns round tunneling construction process, to Heng Chuan position or cut the corner position such as eye turn round construction time use, solve critical coal breakage problem, elevating conveyor slide down, the machine of moving back produces coal problem.Improve safety in production coefficient, improve drivage efficiency, reduce worker's labour intensity, producing coal system is changed into " being flexible coupling " by " Hard link ", remain the accurate of coal dropping point, decrease the clear coal workload of worker, stopped elevating conveyor and to have slided down the generation of accident, need not produce coal by the machine of moving back again, ensure that coal cutting, coaling, transport coal and work continuously, improve drivage efficiency.

Detailed description of the invention

a kind of hanging elevating conveyor turns round tunneling construction process, development machine 8 tunnels corner position in tunnel 4, before tunnel preparation is turned round to horizontal river 5, as schematically shown in Figure 2,2 points (A, B) are selected along roadway direction at top board place, tunnel 4, each point is made a call to two and is played cathead, connects, be fixed on by wire rope 1 between two strands of anchor chains between two anchor poles with anchor chain; On back, select a some C again, select a some D in the top board of horizontal river, each point is made a call to two and is played cathead, connects, be fixed on by wire rope 22 between two strands of anchor chains between two anchor poles with anchor chain; Select 1 some E at horizontal Chuan Dingbanchu along roadway direction, each point is made a call to two and is played cathead, connects, be fixed on by wire rope 33 between two strands of anchor chains between two anchor poles with anchor chain;

as schematically shown in Figure 3, turn round driving time, hang transfer conveyor tail 12 on wire rope 1 by pulley and wire sling 11, under belt is layed in elevating conveyor, the movement that elevating conveyor just can follow unit is slided along wire rope 1; Along with development machine angle of turning round strengthens, constantly the adjustment position of Heave Here on wire rope 1, wire rope 22 and wire rope 33, by three sections of wire rope hanging elevating conveyor positions, makes all to tunnel unit and turns round in horizontal river, and realizes producing coal continuously.

as schematically shown in Figure 4, the 1-16 that constructs arranges, used by elevating conveyor pulley to coordinate upending frame, hanging carry out on a steel cord producing coal in turning process (unit in cutting course elevating conveyor can before and after move freely), fundamentally stopped elevating conveyor and to have slided down the generation of accident; Effectively can control the position of coal dropping point, the coal after cut is directly dropped on conveying coal equipment by elevating conveyor, decreases and spreads coal, effectively can alleviate the workload of the clear coal of worker.

the 17-21 that constructs arranges, and wire rope is adjusted to wire rope 22 position in Fig. 2, need not produces coal by the machine of moving back again, ensure that coal cutting, coaling, transports coal and work continuously;

as schematically shown in Figure 5, during construction 22-35 row, unit just turns, and adjustment makes wire rope 33 hang elevating conveyor point in horizontal river, has stopped reprint and slide down.
