Abstract
The utility model relates to a buffering supporting roller group in a belt conveyer, which is mainly characterized in that both ends of a middle supporting roller and one end of two side supporting rollers are in pin connection on a buffer which is arranged. A supporting roller frame is composed of a cross beam and side supporting roller supporting frames which are hinged on both ends of the cross beam, and one end of the two side supporting rollers is connected with a contiguous side supporting roller supporting frame by a movable connector. When the utility model is used, a conveying belt and each supporting roller are elastically lower platen downwards pressed under the action of materials, which overcomes hard impact and collision. In addition, the conveying belt and each supporting roller are effectively protected, the service life is extended, and production cost is reduced. The utility model is suitable for the starting end of a belt conveyer with drop height.
Description
The utility model relates to a kind of belt load transfer device, relates in particular to a kind of impact idler group.
Band conveyor is the mine; electric power; the harbour; chemical industry; industries such as metallurgy are used a kind of comparatively widely load transfer device; mainly constitute by some groups of carrying roller groups and load-transfer device; difference according to use occasion; the band conveyor that has is very long; and form by several sections; between adjacent two sections individual drop is arranged; when the material on the epimere load-transfer device is fallen hypomere load-transfer device top; because the influence of factors such as the deadweight of material and speed; existing carrying roller group and load-transfer device damage easily; for this reason; manufacturing enterprise is provided with several rubber bumper ring on middle idler roller and two side rollers, this transformation makes between load-transfer device and the carrying roller buffering, has played protection load-transfer device and carrying roller to a certain extent; but facts have proved that this transformation can't fundamentally solve load-transfer device and carrying roller rapid wear problem.
The purpose of this utility model provides a kind of effective protection load-transfer device and carrying roller to reduce the impact idler group of damaging to greatest extent under the material impact at the problem of above-mentioned existence.
The technical solution of the utility model is such: a kind of impact idler group, the side roller that comprises carrier roller frame, middle idler roller and middle idler roller both sides, the axle that it is characterized in that the axle at middle idler roller two ends and an adjacent side carrying roller all pin joint on the energy disperser that is provided with between two carrying rollers, energy disperser is fixed on the crossbeam of carrier roller frame, carrier roller frame is propped up by crossbeam and crossbeam two ends pivotally attached side roller and is configured to, and the active connection through being fixed on the side roller support between the other end of two side rollers and the adjacent separately side roller support is connected; Energy disperser is made of the spring that axle sleeve that is nested with on buffer shaft, the buffer shaft and axle sleeve are nested with outward, the lower end of buffer shaft pass on the crossbeam hole after the predetermincd tension regulating part that nut and spring chair constitute fix; Intrinsic pressing plate on the buffer shaft in the energy disperser, pressing plate is greater than the diameter of following pressing spring; The axle of buffer shaft pressing plate bottom can be the prolongation axle with the upper axis coaxial line, can the upper axis axis be mid point also, and both sides equidistantly are provided with and prolong axle, prolongs to be nested with axle sleeve on the axle and axle sleeve is nested with spring outward; Active connection is made of nut, spring chair and the threaded pin that passes side roller support hole, and the pivot pin of an end of threaded pin and side roller one end connects.
The utility model with the side roller one end pin joint of middle idler roller and both sides on the energy disperser that is provided with; the other end of side roller is connected through active connection with the side roller support; add between side roller support and the crossbeam hinged; under the effect of material, load-transfer device, middle idler roller and two side roller elasticity press down, and have overcome hard collision during use; load-transfer device and each carrying roller have effectively been protected; prolonged service life, reduced productive costs, the utility model is applicable to the top of the band conveyor of drop.
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is the utility model side-looking structural representation;
In the accompanying drawing: the 1st, side roller support, the 2nd, side roller, the 3rd, crossbeam, the 4th, buffer shaft, the 5th, spring, the 6th, hinge, the 7th, load-transfer device, the 8th, axle sleeve, the 9th, active connection, the 10th, predetermincd tension regulating part, the 11st, middle idler roller, the 12nd, pressing plate.
Further specify the utility model in conjunction with the accompanying drawings and embodiments, the utility model is by carrier roller frame, middle idler roller 11, the side roller 2 of middle idler roller 11 both sides, the energy disperser that is provided with between the adjacent carrying roller constitutes, the axle at middle idler roller 11 two ends and side roller 2 pivot pins of an adjacent side are connected on buffer shaft 4 ends of energy disperser, energy disperser is by buffer shaft 4, axle sleeve 8, spring 5 constitutes, be nested with axle sleeve 8 on the buffer shaft 4, be nested with spring 5 on the axle sleeve 8, one end of buffer shaft 4 passes the corresponding hole on the carrier roller frame center member 3 after the predetermincd tension regulating part 10 that nut and spring chair constitute is fixing, pressing plate 12 is set on the buffer shaft 4, pressing plate 12 is greater than the diameter of the spring 5 that presses down, axial region under the pressing plate 12 can be the prolongation axle of top buffer shaft 4 coaxial lines, can buffer shaft 4 axis be mid point also, the both sides vertical with the crossbeam transverse horizontal equidistantly are provided with and prolong axle, prolong on the axle and be nested with axle sleeve 8 respectively, the axle sleeve 8 outer springs 5 that are nested with, each prolongs, and axle one end passes corresponding hole on the crossbeam 3 respectively after predetermincd tension regulating part 10 is fixing; Carrier roller frame is made of through hinge 6 pivotally attached side roller supports 1 crossbeam 3 and crossbeam 3 two ends, be connected through active connection 9 between one end of side roller 2 and the adjacent side roller support 1, active connection 9 is made of threaded pin, spring chair and nut, and the pivot pin that threaded pin passes the Kong Houyu adjacent edge carrying roller on the side roller support 1 connects; On middle idler roller of the present utility model and the side roller rubber bumper ring can be set, also can no longer be provided with, because whether the rubber bumper ring is provided with insignificant under structure of the present utility model.When using on manufacturing line, load-transfer device and middle idler roller, side roller integrated buffer press down under the material impact, and the side roller support is little inwards to incline, and has decomposed the impulsive contact force of material, have protected load-transfer device and each carrying roller effectively.
