The belt conveyer is widely used in the mass transport.When conveying granular, granular material, can adhere to some materials usually on the belt conveyor, these materials can fall down in the backhaul section of belt conveyor, scatter in the work-yard and cause environmental pollution, even be brought into and cause conveyor belt damage in the cylinder.In the prior art, adopt a blade that the material on the belt conveyor backhaul section is scraped off, but blade is not provided with suitable moment regulating device, blade can apply bigger thrust and influence the normal operation of belt conveyor in the belt conveyor operational process belt conveyor; Simultaneously, existing swabbing pig can only be adjusted thrust towards a direction, also is inconvenient to adjust in practice.
Summary of the invention:
The object of the present invention is to provide a kind of tension device, described this tension device will solve the technical matters that can not regulate belt conveyer cleaning blade pressing power in the prior art.
This tension device of the present invention is by the cleaning axle, gear case, a big gear wheel, a miniature gears, ratchet, torsion spring, axle sleeve, positioning cam and set pin constitute, described axle sleeve is set on the described cleaning axle, the diameter of described big gear wheel is greater than the diameter of described miniature gears, big gear wheel is socketed in an end of axle sleeve, the other end of axle sleeve is set with flange, described torsion spring is set on the axle sleeve, one end of torsion spring is captiveed joint with big gear wheel, the other end of torsion spring is captiveed joint with described flange, the middle part of big gear wheel one end is provided with the cylindrical tube flange, radially be provided with pin-and-hole along big gear wheel in the sidewall of described cylindrical tube flange, radially be provided with pin-and-hole along the cleaning axle in the sidewall of cleaning axle, described set pin passes the pin-and-hole and the pin-and-hole that cleans in the axle sidewall in the cylindrical tube flange sidewall, the outside of torsion spring is arranged with an adapter sleeve, the outer wall of described flange of described adapter sleeve captive joint and described gear case, described miniature gears is arranged in the gear case, miniature gears and big gear wheel engagement, described ratchet is splayed configuration, ratchet is arranged on the excircle of miniature gears, ratchet is connected with the gear case tank wall by a bearing pin, described positioning cam is arranged in the curve of ratchet, the positioning cam is connected with the gear case tank wall by wheel shaft, is provided with a holddown spring between the two ends of ratchet and the gear case tank wall separately.
Further, described cleaning axle is cylindrical tube.
Further, described big gear wheel and miniature gears all are spur gear wheels.
Further, inboard parallel its of described flange axially is provided with porose, and an end of torsion spring inserts in the hole, and parallel its axially is provided with porosely on the big gear wheel spoke, and the other end of torsion spring inserts in the hole.
Principle of work of the present invention is: rotation pinion and big gear wheel, give the torsion spring stored energy, and torsion spring applies moment of torsion by big gear wheel, set pin and cleaning axle to blade, and blade is contacted with belt conveyor.Rotate the positioning cam, can make ratchet respectively through three kinds of positions, thereby can select miniature gears to clockwise rotate or rotate counterclockwise or freely rotate.If sweeper blade is a formal dress, will transpose that cam rotates counterclockwise and, make right ratchet under the holddown spring effect, compress miniature gears by screw retention, miniature gears can only clockwise rotate.When rotation pinion makes torsion spring reach desired moment of torsion, set pin is inserted between big gear wheel and the cleaning axle, and then the cam of will transpose rotates counterclockwise and makes ratchet disengaging miniature gears.If sweeper blade is anti-dress when installing, then reach same effect by reverse adjustment positioning cam.
The present invention compares with prior art, and its effect is actively with tangible.The present invention is provided with the torsion spring stored energy in tension device, sweeper blade is produced moment of torsion, makes it to compress belt conveyor, adopt gear mechanism that moment is amplified, laborsaving during adjustment, by the rotation direction of positioning cam by ratchet pinion mechanism, can realize two-way adjustment, easy to operate.
