Abstract
A mining clean-up scraper conveyor belongs to the transport machinery of the coal mine. The conveyor is used to solve the problems of a tilt angle of a reducer being big, the lubrication of the reducer being imperfect, the reducer leaking the oil, a centrifugation friction axle connecting device entering the oil and slipping to case the fire hazard, an electric motor burning, clipping a chain and breaking the chain in a lead-over groove and the materials being easy to fall when the raise transportation of the coal mine with the big tilt angle of 15 degree to 25 degree is conducted. The mining drag conveyor is composed of the explosion-proof electric motor through the centrifugation friction axle connecting device, the reducer, a circular ring chain wheel and a tail roller driving a clean-up scraper on a circular ring chain. The advanced point of the mining clean-up scraper conveyor is: the conveyor through a new headstock alters the setting angle of the electric motor, the axle connecting device and the reducer on a head unit to make the angle be nearly horizontal when the raise transportation with the big tilt angle is conducted. The lower side of the middle plate of the lead-over groove is provided with an anti-clip chain plate and the loading deepness of a middle groove is enlarged. The conveyordecreases the accident rate and the material consumption. The mining clean-up scraper conveyor also can reduce the driving length and the number of the transportation equipments.
Description
Technical field:
The utility model relates to a kind of mine anti-explosion slat conveyer, is particularly useful under the coal mine high spud angle go up a hill transportation raw coal or rock.
Background technology:
At present, fortune angle≤15 ° are gone up in mine flight conveyer design, when going up fortune greater than 15 °, have that the head drive device inclination angle is big, leakage of oil, fault is many, material tumbles, transportation volume is low, the backhaul chain is in problems such as the easy jams of transitional slot.
Summary of the invention:
The purpose of this utility model provides that a kind of electrical motor when 15 °～25 ° high spud angles upwards transport under coal mine, coupler, retarder operating mode are good, reliable operation, material do not tumble, and the backhaul chain can be by the mine flight conveyer of jam at transitional slot.The technical solution of the utility model solves: a kind of mine flight conveyer, by flame-proof electric motor centrifugal friction formula coupler, retarder is formed by the scraper plate that annulus sprocket wheel and aircraft tail cylinder drive on the annular chains, the mount pad center line of retarder and the base of headstock are installed on the headstock are had a setting angle, transitional slot is equipped with the anti-sticking carrier bar, and the intermediate channel design strengthens the degree of depth of loading section.Retarder is installed on the headstock with bolt, and electrical motor is connected to a fixed by coupling tunnel and retarder, and there are a stagger angle in their assembling axis and headstock base, and the anti-sticking carrier bar is equipped with in the plate below in the transitional slot.The mount pad center line of mine flight conveyer headstock upper reducer is the Kong Xinwei axle with the assembling reducer output shaft, and vertical rotation and headstock base form behind 20 ° of the stagger angles and location processing.
The beneficial effects of the utility model are: adopt this new type mining slat conveyer, can be implemented in upwards transportation in 15 °～25 ° high spud angle tunnels, and following characteristics are arranged:
Retarder is still 0～5 ° of nearly horizontality work when 1, transporting on the high spud angle, improved the lubricated and transmission performance of retarder, avoided the input shaft leakage of oil, guaranteed that reducer gear, bearing lubrication are good, prolonged retarder service life, reduced fuel consumption, equipment oil leakage when having solved fortune on the high spud angle, the hard nut to crack that accident rate is high.
2, avoided gear reducer lube to bleed and connect in the tube, thereby guaranteed that the centrifugal friction coupler is non-slip, not on fire.
3, because flame-proof electric motor is in nearly horizontal operation, operating mode is improved, fault is few, and oil, the water in the coupling tunnel can not improve the electrical motor sealing property from shaft extension end inflow motor simultaneously, has avoided the electrical motor scaling loss.
4, chain-drive section flame-proof electric motor installation site helps the heat radiation of electrical motor, can be by the float coal pile things on, and working environment is good, has prolonged the electrical motor life-span.
5, intermediate channel has improved the efficient loading degree of depth and basal area, and material does not tumble, and has improved last fortune inclination angle and operational throughput.
6, the anti-sticking carrier bar is installed in the transitional slot, has been prevented that chain jam, chain rupture from taking place.
7, improved the serviceability rate of equipment, reduced accident rate, reduced fitment material consumption, the plant maintenance running expense descends.
8, the maintenance of equipment cycle stretch-out is more than 6 times, and prolong the service life of flame-proof electric motor, retarder, coupler greatly.
9, because present technique has improved on the mine flight conveyer fortune permission inclination angle, bring up to 25 ° by 15 °, when mine design is constructed, can reduce tunnelling length and transportation device quantity, speed up the work.The transportation elevation is pressed 100m and is calculated, if go up a hill by 15 ° of inclination angle drivings, belt heading length is 386m.And by 25 ° of inclination angle drivings, tunnel length only is 237m, can reduce tunnelling 149m, reduces 2 ones of slat conveyers, saves a large amount of expenses and time.
