Abstract
The utility model relates to a tail traction device for a telescopic belt conveyer for a coal mine, which is provided with a tractor. One side of the tractor is provided with a winch, and the other side is provided with a tension force buffering indicator. A traction rope is connected between the winch and the tension force buffering indicator for connecting the winch and the tension force buffering indicator. The traction rope is wound around a set of fixed pulleys and a set of movable pulleys. The device can realize the tail of the conveyer to continuously and quickly draw through a self moving mode. The utility model has the characteristics of simple structure, convenient operation and maintenance, safe use, etc. The utility model can better meet the requirements of the quick propulsion of the integrative mining working face of a coal mine, high production and high efficiency.
Description
The utility model relates to the extensible belt conveyor tail that a kind of coal mine fully-mechanized mining working crossheading uses and pulls device.
At present, moving of all kinds of extensible belt conveyor tails of China's coal-mine down-hole fully-mechanized mining working crossheading, all adopt the traction of hydraulic actuating cylinder chain sprocket mechanism, one or several hydraulic actuating cylinders promptly are set on the roadway floor in tail the place ahead, this cylinder is connected in series with closed chain, chain is walked around the one group of sprocket wheel that is fixed in the place ahead, and its two ends are connected with tail.When the hydraulic actuating cylinder indentation, chain shortens, thus the reach of traction tail, and this class mechanism traction tail moves all to be interrupted and carries out, and needs constantly to adjust chain and telescopic hydraulic cylinder in the distraction procedure.Required operating personal is many, troublesome poeration, inefficiency, and need accessory equipments such as configuration hydraulic power unit, pipeline, complex structure, expense height, its topmost defective are haulage speed low (being lower than 0.2 meter/minute), have therefore restricted the quick propelling of coal-face.
The purpose of this utility model is to realize high yield for satisfying coal mine fully-mechanized mining working and other face, require efficiently and provide a kind of simple in structure, compact, operation and easy to maintenance can pull device by extensible belt conveyor tail continuous, centering traction fast.
Main points of the present utility model have been a tractor truck, and this tractor truck one side is equipped with winch, and opposite side is equipped with tension force buffering indicating device, are connected with hauling rope, this hauling rope pile warp assembly pulley between winch and the tension force buffering indicating device.
Described tractor truck is by crossbeam, longeron and support are fixedly connected into a box frame, be fixed with a pair of movable pulley and tension force buffering indicating device at following front cross rail two ends, following after cross member two ends are fixed with one group of hinged support, and respectively are equipped with one on the roller rack that above-mentioned two crossbeams link to each other and lift roller.Front and back wheel or sled are equipped with in the tractor truck bottom.
Described winch is fixed on tractor truck one side and the chassis that following longeron is captiveed joint.
Described assembly pulley comprises a pair of fixed pulley and a pair of movable pulley, and fixed pulley hangs on two pillars in tractor truck the place ahead, and movable pulley then is fixed on the bearing at following front cross rail two ends.
Working process of the present utility model as shown in Figure 1, and is at first that tractor truck and conveyer tail is hinged at the tractor truck rear portion, starts winch motor then, drives the reel running through speed reduction gearing, makes the hauling rope rollback to reel.Because a pair of movable pulley of hauling rope pile warp and a pair of fixed pulley, make its break-in and produce deceleration, boosting function, therefore when hauling rope was regained, tractor truck just was pulled common reach together with tail, the hauling rope gross tractive force can reach four times of winch output tractive force, and moving velocity then is 1/4 of a rope speed.
Pulling device with existing crossheading extensible belt conveyor tail compares, the utility model can be realized continuously, centering is moved traction certainly fast, its speed improves 15-25 doubly, the one-time continuous draft travel can reach more than 20 meters, can satisfy preferably that fully-mechanized mining working advances fast, the requirement of high-yield and high-efficiency.The utility model also has simple in structure, compact, and accessory equipment is few, operation, adjustment and easy to maintenance, characteristics such as safe in utilization.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the birds-eye view of Fig. 1.
Provide embodiment of the present utility model below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, the utility model mainly comprises a tractor truck, assembly pulley and hauling rope, tractor truck (6) be one by front and back entablatrance (6a) (6b), front and back cross sills (6c) (6d), last longeron (6e) (6f), following longeron (6g) is (6k) box frame becoming of bolt together of (6i) and front and back support (6j) (6h).The front cross rail of this framework (6c) two ends are fixed with pulley support, with bolt a pair of movable pulley (4) are arranged on the bearing, are used for the break-in of haulage cable.The right-hand end of this crossbeam has tension force buffering indicating device (5) with bolt, and this indicating device comprises energy disperser and compression indicator, the steel wire rope tension when being used to cushion and indicate traction.After cross member (6d) two ends are fixed with a pair of hinged support (10), are used for being connected with loading frame.Lift roller (8) with being equipped with on the roller rack that crossbeam (6c) (6d) links to each other, be used for the load-transfer device that makes the return trip empty under the support.Hang with two groups of Hinge linked supporting roller groups (9) at last longeron (6e) on (6f), be used for carrying on the support load-transfer device.Tractor truck left-hand stringer (6h) (6i) upward has the chassis with bolt, is fixed with winch (7) on the chassis, and this winch comprises motor (7a), and retarder (7b) and reel (7c) can adopt existing mining explosion-proof type electric winch.One end of haulage cable (3) is fixed on the capstan drum, and other end pile warp fixed pulley group (2) and running block (4) join with tension force buffering indicating device (5), are used for transmitting tractive power.On pillar (1), fixed pulley adopts the general single-wheel whip hoist of hook type to above-mentioned fixed pulley (2) with steel wire loop.Described pillar is a hydraulic prop, and this pillar vertical fixing is used for the anchoring of pulley on the roadway floor of tractor truck the place ahead.One group of front vehicle wheel and one group of rear wheel (11) are equipped with in the tractor truck bottom, and set of wheels uses the V-type bolt on the wheel mount before and after the tractor truck, the rolling of leading in orbit when being used to draw.
