Abstract
A large dip angle scraper conveyor comprises a power device, a machine nose, a machine tail, and a connecting groove connected between the machine nose and the machine tail. A support base of the machine nose is arranged on a lower portion of the machine nose, and an installation face of the support base of the machine nose is an inclined face and is parallel to the operation direction of the scraper conveyor. An included angle between the inclined face and a horizontal surface is alpha and an extending plate is welded on an upper portion of a scraper of the scraper conveyor. The bottom of the connecting groove in the middle of the scraper conveyor is provided with a U-shaped supporting base and a height of the U-shaped supporting base is matched with the height of the extending plate. The maximum adaptive inclined angle of a coal seam of the machine nose is 40 degree. The scraper conveyor can incline as a whole, and the self-height of the scraper is increased due to the extending plate of the scraper, and therefore transport capacity under large dip angle is ensured. The U-shaped supporting base on the lower portion of the connecting groove in the middle of the scraper conveyor provides an enough height for the scraper to pass. The large dip angle scraper conveyor has the advantages of being advanced in design, reasonable in structure, stable in operation, safe and reliable, and suitable for longwall coal mining under various geological conditions and is an ideal large dip angle scraper conveyor.
Description
Technical field
The technical field of the utility model coal-cutting machinery equipment particularly relates to a kind of high inclination-angle drag conveyor.
Background technology
The coal wall is the geological environment of a complicacy under the coal mine, and Coal Seam Thickness Change is big, and the coal seam mostly is that ramp type distributes; Surface relief is big, and the seam mining tunnel is long, has brought a lot of difficulties for longwall mining and transportation; The most frequently used haulage device of longwall mining work plane is a drag conveyor, because the coal seam changes, the slope distributes, surface relief, regular meeting differs head, delivery chute, the tail height of drag conveyor; Oblique inclination; Carry not freely, even retardance, coal piling cause security incident.
The drag conveyor that uses at present; Mostly be the design of small inclination ground; Head, delivery chute, tail all same tunnel relatively than the small inclination plane on, meet that the coal seam changes greatly, angle of inclination coal-face greatly, can't accomplish and fail the coal operation normally.
Can occur whole slippage downwards when drag conveyor is arranged in large inclination working surface, intersection is prone to produce base plate collapses, and makes head declines of taking advantage of a situation, and coal appears back in following chain road, formation coal piling phenomenon, the operation of obstruction ordinary production.
The utility model content
The purpose of the utility model is in order to address the above problem, a kind of high inclination-angle drag conveyor to be provided.
The technical scheme of the utility model is: a kind of high inclination-angle drag conveyor; Comprise power set, head, tail, be connected the link slot between head and the tail; The head bottom is provided with the head supporting seat; The installed surface of said head supporting seat is inclined-plane and parallel with the traffic direction of this drag conveyor, and the angle of this inclined-plane and horizontal plane is α, and the scraper plate top of drag conveyor is welded with extension plate; The intermediate channel bottom of drag conveyor is provided with U-shaped supporting seat, the height of this U supporting seat and the matched of extension plate.
Described α≤40 °.
Described power set comprise motor and reductor, and motor and reductor along continuous straight runs are provided with.
The ledge top of the intermediate channel of described drag conveyor is provided with backplate, the matched of this backplate height and extension plate.
The beneficial effect of the utility model
Inclining in the head maximum adaptation coal seam of this utility model is 40 °, but the drag conveyor integral inclination, and the scraper plate extension plate has been increased the oneself height of scraper plate; Guaranteed the transport capacity under the high inclination-angle state, the U-shaped base plays enough height in the intermediate channel lower support passes through this conveyer advanced design to extension plate; Topology layout is reasonable, operates steadily, and is safe and reliable; The longwall mining that can adapt to multiple geological conditions is very good high inclination-angle drag conveyor.
Description of drawings
Fig. 1 is the main TV structure sketch map of this high inclination-angle drag conveyor;
Fig. 2 is the A-A cross section structure for amplifying sketch map of Fig. 1;
1. supporting seats among the figure, 2. power set, 3. head, 4. link slot, 5. tail, 6. backplate, 7. scraper plate, 8. extension plate, 9.U shape supporting seat.
The specific embodiment
Embodiment: referring to Fig. 1-Fig. 2; A kind of high inclination-angle drag conveyor among the figure; Comprise power set, head, tail, be connected the link slot between head and the tail, the head bottom is provided with the head supporting seat, and the installed surface of said head supporting seat is inclined-plane and parallel with the traffic direction of this drag conveyor; The angle of this inclined-plane and horizontal plane is α; The scraper plate top of drag conveyor is welded with extension plate, and the intermediate channel bottom of drag conveyor is provided with U-shaped supporting seat, the height of this U supporting seat and the matched of extension plate.Described α≤40 °.α among this embodiment is preferably 36 °.Described power set comprise motor and reductor, and motor and reductor along continuous straight runs are provided with.The ledge top of the intermediate channel of described drag conveyor is provided with backplate, the matched of this backplate height and extension plate.
The course of work basically identical of this machine course of work and general drag conveyor; Different places has increased extension plate on scraper plate top exactly; And bottom intermediate channel, having increased the U-shaped supporting seat, its accommodation has been expanded at the inclination angle that so just can improve whole scraper plate machine.
