Description

Shortwall scraper plate transfer conveyor

Technical field:

The utility model relates to a kind of transportation device in driving surface and tunnel, particularly a kind of scraper-type conveying arrangement.

Background technology:

Existing shortwall load transfer device, still use the slat conveyer of coal wall, usually form by driving surface slat conveyer and stage loader, the two has included head (power pack section), tail, assembly such as intermediate channel and scraper chain, coal is transported to buttock by the driving surface slat conveyer along driving surface, unload the stage loader (scraper-type) of giving vertical with driving surface (or at an angle) and having certain drop then, realization is turned round and is transported to the transportation lane, reprint to follow-up belt conveyer, this structure has two cover power (head), increase equipment cost, and maintenance workload is big, serviceability also reduces.

The utility model content:

Technical problem to be solved in the utility model provides a kind of shortwall scraper plate transfer conveyor, energy simplified apparatus structure, and cost-cutting, and can improve serviceability.

The technical scheme in the invention for solving the above technical problem is: shortwall is made up of transportation section, the section of turning to and reprinting section with the intermediate channel of scraper plate transfer conveyor, transportation section and reprinting section are linearly, the section of turning to is arc shaped, the smooth-going respectively transportation section that is connected with, the section of turning to two ends forms a continuous one-piece construction with the reprinting section, and the intermediate channel section of turning to one side correspondence is provided with a guide piece.Mining machinery carries coal, the rock cut off to be carried along driving surface in the transportation section of intermediate channel, and at the section of turning to change throughput direction, be sent to continuously and reprint section, i.e. break-in transfers to roadway direction, finishes conventional confguration (a driving surface conveyer and a stage loader) identical functions simultaneously.

The utility model adopts guide piece, makes the break-in operation and have and carry and reprint dual-use function continuously of a scraper plate transfer conveyor, and the simplified apparatus function reduces the cost of manufacture of equipment, and can improve the reliability of equipment operation.

The specific embodiment:

With reference to Fig. 1,2,3, shortwall includes head 1, tail 2, intermediate channel 3, scraper chain 4 and guide piece 5 with the scraper plate transfer conveyor, this device can be supporting with short fuselage single ended shearer, hydraulic support, diagram intermediate channel 3 is vertically to carrying and reprinting, Fig. 1 is the unit head scraper plate transfer conveyor that the shortwall fully-mechanized mining working uses, Fig. 2 is the two-shipper head scraper plate transfer conveyor that short longwall full-mechanized mining technique driving surface uses, the unit head scraper plate transfer conveyor that wide lane driving face used when Fig. 3 was advance mining.

Head 1 is the power pack section that drives scraper chain 4, and shortwall can adopt unit head 1 to drive (as Fig. 1,3) usually; Then drive (as Fig. 2) with two-shipper head 1 in short coal wall, promptly be provided with power pack section at the two ends of scraper chain 4, its structure and existing scheme are same or similar.

Tail 2 is arranged on the other end of scraper chain 4 power pack sections, and for scraper chain 4 solderless wrapped connections, to keep the circulating motion of scraper chain 4, its structure and existing scheme are same or similar.

Intermediate channel 3, it is the main body that scraper plate is carried carrier aircraft, except that the laying shape on plane, all the other structures and existing scheme are same or similar, the laying shape that intermediate channel 3 of the present utility model includes transportation section 33, the section of turning to 32 and reprints 31, three sections of sections is transportation section 33 and reprints section 31 and be linearity that the section of turning to 32 then is an arc shaped, the section of turning to 32 is connected with transportation section 33 respectively and reprints section 31, lays thereby make transportation section 33 be different directions through the section of turning to 32 with reprinting section 31.(Fig. 1,2,3 show turn to 90 °) is smooth-going smooth connection and is one-piece construction between three

section

31,32,33 of intermediate channel 3, transport swimmingly to guarantee coal, rock that scraper chain 4 is scraped in the fortune intermediate channel 3; The camber line subtended angle of the section of turning to 32 can be 60 ° to 120 °, decides according to the different demands of driving surface;

Scraper chain 4 includes the scraper plate of establishing on chain 41 and the chain of putting 42, and its structure and existing side are same or similar, and scraper plate 4 of the present utility model is to carry over intermediate channel 3 to do the break-in campaign, but the two ends solderless wrapped connection of chain 41 has head 1 and tail 2 or two-shipper head 1;

Guide piece 5, include track adjusting wheel 51, wheel shaft 52, bearing support 53 and retaining element etc. and form (as Fig. 4), the track adjusting wheel 51 of guide piece 5, be one to have the wheel body of groove 511, its height can be highly identical or smaller with scraper plate 42, and groove 511 is to carry over wheel shaft to offering, and its width is slightly larger than the thickness of scraper plate 42, the pitch that pitch between its groove and two scraper plates are 42 equates, that the shape of groove 511 can be is circular-arc, trapezoidal, rectangle or other similar geometric; Track adjusting wheel 51 also can be the face of cylinder of not slotting or is the polygon column; Track adjusting wheel 51 is set in wheel shaft 52 and is the cooperation of rolling, and wheel shaft 52 is to be installed in bearing support 53, and bearing support 53 is fixed on the support; Track adjusting wheel 51 center of gyrations of guide piece 5 are positioned at the center of intermediate channel 3 sections of turning to 32 camber lines, and the radius of track adjusting wheel 51 is that the track adjusting wheel 51 that be able to make scraper plate 42 embedded grooves 511 carry over rotation is done the break-in campaign;
