Description
Technical field
The utility model relates to a kind of displacement-type automatic deviation rectifying device that leans forward.
Background technology
Belt conveyer is with load-transfer device, to make the continuous conveying equipment of traction member, carries various bulk materials and work piece.In the commercial production such as mine, electric power, be widely used.Belt conveyer is in operational process, and because belt deflection often appears in a variety of causes, the phenomenons such as stopping production are produced or caused in impact.
Conventional belt conveyer deviation-adjusting carrier roller group is on the architecture basics of common carrying roller group as shown in Figure 1, 2, adds a rotating shaft 9 in the center of carrier roller frame 1, and two ends add correction edger roll 11.
As shown in Figure 5, load-transfer device 12 is during to a side sideslip, and load-transfer device promotes correction edger roll, drives carrier roller frame 1 to take rotating shaft 9 and rotates for fulcrum, so as to rectifying a deviation.L in figure
1, L
2respectively that left carrying roller, right carrying roller are to the horizontal throw at middle idler roller center, ∠ а
1, ∠ а
2the angle of deflection while being respectively left carrying roller, the correction of right carrying roller.
But conventional belt conveyer deviation-adjusting carrier roller group, has the following disadvantages:
(1) the arm of force of edger roll of rectifying a deviation is too little, and correction power is little, rectifying effect is bad.
Rotating shaft be center of turn be also the fulcrum of carrier roller frame carrying, when bandwidth is larger, support obviously not enough.
Utility model content
The technical problems to be solved in the utility model is the above-mentioned defect that how to overcome prior art, and a kind of displacement-type automatic deviation rectifying device that leans forward is provided.
For solving the problems of the technologies described above, originally the displacement-type automatic deviation rectifying device that leans forward comprises carrier roller frame, on this carrier roller frame, be separately installed with middle idler roller, left carrying roller and right carrying roller, and be furnished with two deviation rectification rollers and cross sill, it is characterized in that: it also comprises " Y " font pivoted arm and correction link rod, wherein said " Y " font pivoted arm front portion is provided with front arm prominent before two, its rear portion is provided with the back arm of stretching after, two front arms and back arm junction are provided with rotating shaft, " Y " font pivoted arm is fixed on cross sill by this rotating shaft, described correction link rod bending two ends upwards, correction link rod stage casing and back arm end are fixed together, two deviation rectification rollers are just separately positioned on the two ends of described correction link rod, described carrier roller frame stage casing is fixed on two front arms.
During use, the two ends of cross sill are fixed on to load-transfer device frame both sides, middle idler roller, left carrying roller and right carrying roller are held load-transfer device, and make deviation rectification roller lay respectively at load-transfer device both sides.
So design, when load-transfer device generation sideslip, the deviation rectification roller at deviation correcting device link rod two ends is produced to application force, the rotating shaft of take in " Y " font pivoted arm is rotating fulcrum, drive " Y " font pivoted arm, the rotating shaft of take in the upper plane of cross sill is done circular motion as the center of circle, thereby make carrier roller frame deflection (leaning forward) and produce cross travel, make to be arranged on left carrying roller or right carrying roller application force of load-transfer device to sideslip on carrier roller frame, make load-transfer device revert to normal service direction, make it to reach the effect of correction.
As optimization, described front arm is positioned at middle idler roller below.
As optimization, described cross sill two ends have spacing long slot bore.
The utility model displacement-type automatic deviation rectifying device that leans forward has the following advantages:
(1) the fulcrum rotating is outside carrying roller group axis, deviation correcting device is done circular motion along rotating fulcrum, the existing deflection of deviation-adjusting carrier roller (leaning forward) produces again to the cross travel of adhesive tape center position, has increased the application force between deviation-adjusting carrier roller and adhesive tape, has strengthened the correction dynamics of carrying roller to adhesive tape.
(2) shaft fulcrum is between correction link rod and carrier roller frame, and constantly, the coal on carrier roller frame, load-transfer device and load-transfer device be take rotating shaft as fulcrum with correction link rod and deviation rectification roller, reaches gravitational equilibrium, works more steady in work, the shake while having avoided operation.
(3) the arm of force of deviation correcting device lengthens, and rotation place is provided with bearing, and total is quick on the draw when action operation.The extensively applicable various enterprises and institutions that need to use band conveyor, are particularly suitable for various mines and use.
