Description
The utility model relates to a kind of air-cushion type travelling apron that surges that departments such as mine, metallurgy, coal, building materials, harbour, power station carry bulk material continuously that is widely used in.
At present, be widely used in the mechanical transmission structure form that the continuous travelling apron that transports of bulk material generally all adopts traditional friction-driven principle to make both at home and abroad.According to drawing formula S especially
Go into/ S
Go out≤ e
μ α, S
Go into: scratch tension force into cylinder point; S
Go out: the tension force of scratching out cylinder point.The external load of travelling apron is that the length with travelling apron increases S when length increases
Go intoIncrease,, must concentrate on propulsive effort the S of cylinder in order to drive adhesive tape
Go intoIn this point and the cornerite scope thereof,, the tension intensity of adhesive tape is required external load greater than adhesive tape in this point.Because the haul distance to travelling apron requires more and more longer at present, freight volume is increasing, so require also more and more higher to belt strength, develop into rope traction adhesive tape, folder steel cable belt from cotton tape, vinylon adhesive tape, strong plastic band, its cost is also more and more higher, and relatively large its adhesive tape cost of folder steel cord belt machine accounts for the 40-55% of complete machine, friction destroys serious in haul simultaneously, the good operation of condition four to five years, only about 2 years of difference, its manufacturing technology requires high.Therefore both at home and abroad to the long-distance transportation measure: the one, adopt segmentation that the mode of transfer post is set, promptly be connected, to meet the demands with several sealing-tape machines; The 2nd, in the bottom of carrying branch of a main sealing-tape machine of long distance the sealing-tape machine of several connected head-to-tail small-sized weak points is set, with the segmentation burden, disperse the conveyor belt tension of main sealing-tape machine, but increased cost so again, make structure complicated.The friction-driven sealing-tape machine adopts the idler stand material, loads the back because dangling naturally of adhesive tape is restricted the sealing-tape machine running velocity, and the ubiquity sideslip; accidents such as material are torn, wear and tear, leaked to adhesive tape; often tape swapping, change part, cause shut-down, equipment can not normally be moved.The driving system complexity of friction-driven in addition, drive disk assembly is many, also need set up the corresponding protection measure.Therefore, existing sealing-tape machine is badly in need of improving.
The purpose of this utility model provides a kind of improved travelling apron, it adopts the power driving of surging to replace traditional friction-driven, overcome the shortcoming that friction-driven formula travelling apron exists, effectively simplify transmission device, be convenient to maintenance, reduce equipment investment, significantly reduced cost, and can realize the remote transportation of random length.
The purpose of this utility model is achieved in that this device comprises and utilizes tightening device to be assembled in driven cylinder, adhesive tape and control system thereof on the frame, wherein be processed with the sealing band of the adhesive tape of jet runner by its both sides of the edge, being encapsulated in going up of sealing air water case coils in the air chamber of groove both sides, the nozzle of air water case pressure jet pipe is arranged on adhesive tape runner center, and adhesive tape backhaul section is installed in the lower wall groove top of unloaded gas tank.
Because the utility model adopts the adhesive tape that is processed with the jet runner, and it is encapsulated on the sealing air water case that the pressure jet pipe is housed on the dish groove, pressed gas holds up adhesive tape through last dish groove through hole, utilize the High-Pressure Water of pressure jet pipe ejection to be injected in the adhesive tape jet runner, under air cushion and flow action, the operation of driving adhesive tape, replace traditional mechanical drive and idler stand, operate steadily so have, shockproof and wearing and tearing, overcome rubber belt from deviating in the prior art effectively, accident such as tear takes place, be convenient to the maintenance and the maintenance of equipment, significantly improved work efficiency and reduced device fabrication cost and service expenditure.Because of the propulsive effort that surges is at the continuous rectangular distribution of adhesive tape carrying section, eliminated the disadvantage that propulsive effort is concentrated in the prior art, floating holder realizes high-speed cruising by air cushion, when same operating mode is finished identical operational throughput, comparable frictional transmission conveyer reduces tape width and the requirement that reduces belt strength, need not the high strength adhesive tape, when finishing the long-range conveying operating mode of long distance, compare with existing conveyer, this device has been cancelled motor-driven hydraulic coupler, high-power hard flank of tooth retarder, drivings device such as high strength encapsulate belt, it is about 1/3rd to reduce manufacturing cost, so the utility model is very easily applied.
