Abstract
The invention provides a hydraulic tension device for a belt conveyor. The problem to be solved is that the tension force required for a rubber belt is larger and larger along with the continuous development of the belt conveyor in the direction of large bandwidth and large traffic volume so that the traditional tension device and method can not be suitable. The hydraulic tension device has the technical essential that the outer side of a roller frame at the tail part of a rubber belt machine is used as a tension frame, a screw passes through the tension frame, two nuts are respectively matched with the screw at both sides of the tension frame, the inner end of the screw is fixed on a roller bearing seat, a plurality of pairs of positioning grooves are correspondingly arranged on two tracks of the roller, both ends of a locking seat are provided with pluggable locking blocks which can enter the grooves of the tracks to fix the locking seat when the locking seat moves on the tracks, and a lifting jack is placed on the locking seat. The hydraulic tension device has the advantages of easy operation and time and labor saving and is especially suitable for the belt conveyor with large bandwidth, large traffic volume and high tension force.
Description
Technical field
The present invention relates to belt conveyor slack adjuster, is fluid-pressure straining device specifically.
Background technology
Spiral tensioning device is adopted in the tension of short range belt conveyer (horizontal captain is less than 80m) at present usually, and this take-up device is fully by the manpower manual operations, each adjustment need at least two people simultaneously, turn screw rod synchronously and just can finish.Its principle of work is to turn rotating screw rod and not rotatable nut with external force, makes balladeur train drive stern barrel by screwing of screw thread and moves on the tailstock channel-section steel, to reach the purpose of tensioning adhesive tape.This take-up device only is adapted at using on the low tightening force belt conveyer of little bandwidth, little freight volume.Along with belt conveyer constantly develops to big bandwidth, high freight volume direction, the required tightening force of adhesive tape is increasing, and above-mentioned take-up device and method can't be suitable for.
Summary of the invention
For addressing the above problem, the object of the present invention is to provide a kind of Hydraulic Press Tension Device of Belt Conveyor, it not only can reduce labor intensity of operating personnel greatly, can also be suitable for the sealing-tape machine of big bandwidth, high freight volume.
The object of the present invention is achieved like this: the outside with sealing-tape machine stern barrel framework is the tension frame, screw rod passes the tension frame, two nuts cooperate with screw rod in tension frame both sides respectively, the inner end of screw rod is fixed on the drum shaft bearing, correspondence is provided with some to detent on two tracks of cylinder, the two ends of locking bed are provided with pluggable latch segment, but in the groove of latch segment injection locking bed are fixed when locking bed moves to groove in orbit, and jack is placed on the locking bed.
When needs tensioning adhesive tape, to strain the inboard nut of frame earlier unclamps away from the tension frame, give the pressurization of hydraulic pressure jack by hydraulic efficiency pressure system then, promote the drum shaft bearing moves a hydraulic cylinder travel in orbit to tension frame direction distance, stroke of hydraulic actuating cylinder equals the distance between adjacent two detents on the track.Then, under the situation that hydraulic jack keep-ups pressure, tighten two nuts cylinder is located.The jack pressure release, its piston is recovered to initial position, and locking bed is moved the distance of a detent along track to tension frame direction, then latch segment is inserted in the groove, is screwed, and finishes the process of once straining.This process can repeat repeatedly, but should can obtain required tension force until adhesive tape with in the groove scope at track.
Compared with prior art, the invention has the beneficial effects as follows: easy operating, time saving and energy saving is particularly suitable for the belt conveyer of big bandwidth, large conveying quantity, high tightening force.
Description of drawings
Further specify the present invention below in conjunction with accompanying drawing.
Accompanying drawing is a scheme drawing of the present invention.
The specific embodiment
The outside with sealing-tape machine stern barrel 13 frameworks is a tension frame 14, screw rod 1 passes the tension frame, two nuts 2,3 cooperate with screw rod in tension frame both sides respectively, the inner end of screw rod is fixed on the drum shaft bearing 4, correspondence is provided with some to detent 11 on two tracks 10 of cylinder, the two ends of locking bed 8 are provided with pluggable latch segment 7, but in the groove of latch segment injection locking bed are fixed when locking bed moves to groove in orbit, and jack 6 is placed on the locking bed.
When needs tensioning adhesive tape, to strain the inboard nut 3 of frame earlier unclamps away from the tension frame, give the pressurization of hydraulic pressure jack by hydraulic efficiency pressure system 5 then, promote the drum shaft bearing moves a hydraulic cylinder travel in orbit to tension frame direction distance, stroke of hydraulic actuating cylinder equals the distance between adjacent two detents on the track.Then, under the situation that hydraulic jack keep-ups pressure, tighten two nuts cylinder is located.The jack pressure release, its piston is recovered to initial position, and locking bed is moved the distance of a detent along track to tension frame direction, then latch segment is inserted in the groove, and is fixing with screw 9, finishes the process of once straining.This process can repeat repeatedly, but should can obtain required tension force until adhesive tape 12 with in the groove scope at track.
