Abstract
The invention provides a horizontal extension loader for a subsurface scraper of a coal mine. The loader comprises a scraper, a scraper chain, a scraper conveyer bracket, a riding wheel, a chain wheel, a clutch, support cars, traction support cars and the like, wherein the clutch can realize smooth combination of the horizontal extension loader for the subsurface scraper of the coal mine and a whole mine car, as well as the function of constant tension automatic separation; and the orderly flexibility of the distance between two adjacent support cars realizes continuous loading of the whole mine car. The horizontal extension loader has the characteristics of high loading efficiency, simplicity in operation, compact structure and easiness in design and manufacture.
Description
Technical field
The present invention relates to the horizontal extension elevating conveyor of a kind of coal mine lower scraping plate and belong to the mining machinery class.
Background technology
Coal is the main energy sources of China, in a very long time from now on, remains China's main energy sources.Giving full play to the coal resources advantage, base oneself upon coal, base on our country, be the reality and the inevitable choice of China's energy industry development, so the safe coal high-efficiency mining has very important significance.
At present, the load mode of taking under domestic most coal mine is to load mineral to mine car by loader, transports mine then, and what it was taked is once to load one to two joint mine car, and the neat more piece mine car of the collection that manually switches tracks is transported by electric locomotive together.The problem that it brings is that underworkings is required to widen, and transports efficient and reduces, thereby increased traffic cost and labour intensity.So be necessary to make improvements, reach cost-cutting, enhance productivity.Also developed the cargo-carring specialized equipment in some down-holes both at home and abroad for this reason, reprinted train as " the bucket type reprinting train ", " the self-control bridge-type is reprinted belt feeder " and the belt (scraper plate) that exist on the market.It is by hydraulic efficiency pressure system trolley to be held up order by mine car that bucket type is reprinted train, loads successively from front to back, though this invention makes the efficiency of loading increase to a certain extent, does not fundamentally solve the continuity of Load System; " the self-control bridge-type is reprinted belt feeder " is with gantry support belt transporter to be suspended on the mine car, disposable continuous loading six joint mine cars, though efficiency of loading can be brought up to original 3～6 times theoretically, but still do not solve the above mine car of seven joints and load problem continuously, this system architecture is huge simultaneously, move difficulty, under the rugged environment of down-hole, its reliability service is difficult for guaranteeing; It is to unload or the side dumping mine car is transformed and formed the end of with that belt (scraper plate) is reprinted train, improvement cost is higher, many belts (scraper plate) machine that needs train top during loading in the adjacent mines workshop in order back and forth transposition influenced efficiency of loading and continuity, because belt (scraper plate) machine has increased load on mine car, other makes other purposes of mine car restricted during transportation.
Summary of the invention
The present invention is for fear of the shortcoming of background technology, solves to load continuity problem, proposed a kind of simple to operate, compact conformation, cost is low, and the horizontal extension elevating conveyor of coal mine lower scraping plate easy to maintenance.
The present invention solves the scheme that its technical matters adopts: the width support identical with the mine car width set up in its slat conveyer bottom, at the uniform support roller of the down either side of support, it can be crouched on the mine car edge, and roll-sliding relatively.Simultaneously the maximum extensible Design of length of the horizontal extension elevating conveyor of coal mine lower scraping plate is equaled the length of a row mine car, thereby can realize underground ore is loaded in every joint mine car of a row mine car continuously.
The present invention compares with background technology, and its advantage is:
1) this invention free relatively rolling-operation on mine car that can crouch can solve the cargo-carring continuity problem in down-hole by actv.;
2) this invention has economized the bridge type suspension support, and is in light weight, compact conformation, and operation is convenient, and manufactures and designs easily;
3) this invention does not have hydraulic efficiency pressure system, provides cost savings greatly;
4) mine car of using of this invention is without any need for transformation, and is applicable to the train of the following mine car of 15 joints;
5) this invention makes the loading continuity be guaranteed that fully efficiency of loading is higher.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
The horizontal extension elevating conveyor of Fig. 1 coal mine lower scraping plate
The specific embodiment
Figure 1 shows that an embodiment of the horizontal extension elevating conveyor of coal mine lower scraping plate basic structure, a kind of high efficiency is adorned continuously and is reprinted equipment, comprises scraper plate 1, scraper chain 2, slat conveyer support 3, support roller 4, sprocket wheel 5, power-transfer clutch 6, (8～12) supported cart 7 and (one) traction supported cart 8 etc.9 is the loader under the coal mine, and 10 is mine car.The end of the horizontal extension elevating conveyor of scraper plate may extend to the mine car 10 first segment places behind the electric locomotive, the width of slat conveyer support 3 is identical with the mine car width, the numerous support rollers 4 that are contained in slat conveyer support 3 bottoms are both sides and are symmetrically distributed, be stuck on the both sides of the edge of mine car, make the steady running of the horizontal extension elevating conveyor of scraper plate transmit; Mine car 10 final sections are connected with supported cart 7 (Fig. 3) by power-transfer clutch 6 (Fig. 2); Traction supported cart 8 is captiveed joint with slat conveyer support 3 heads, and provides power for the horizontal extension elevating conveyor of scraper plate; The numerous scraper plates 1 of scraper chain 2 tractions move under the drive of sprocket wheel 5, realize the mineral transportation; Power-transfer clutch 6 (Fig. 2) is by being fixed on clutch body 11 on the supported cart, can forming with vital partss such as mine car bonded assembly plug 12, bulb bearing pin 13 and springs 14, adjustment by spring 14, can realize that plug 12 inserts combination smoothly, and decide the function that pulling force breaks away from; Involve by steel rope 16 between 8～12 supported cart 7 (Fig. 3), they can be according to the cargo-carring progress of a row mine car, in 0～2.5 meter scope, adjust distance each other, the speed that steel rope 16 was rolled up, put to reel 17 can realize and wheel 18 external diameter linear velocity basically identicals and synchronous that 15 for supporting car body.
When loader 9 loads, the staff can be according to the present invention scraper plate 1 and the transporting rate of scraper chain 2 and the capacity of mine car etc., estimate and the electric locomotive speed of a motor vehicle.Support roller 4 is purpose mades as required, and intensity and wear-resistingly all meet the demands has guaranteed the transmission stability of load-transfer device.
During present embodiment work, be the horizontal extension elevating conveyor of this coal mine lower scraping plate to be extended crouch volt on a row mine car, move relatively in order, realize loading continuously by both.
