Abstract
The invention discloses a novel structure of a buffering supporting roller, which consists of a side supporting roller bracket, a middle supporting roller, side supporting rollers arranged on two sides of the middle supporting roller respectively, and a buffer arranged between adjacent supporting rollers, wherein shafts at two ends of the middle supporting roller and a side supporting roller shaft pin on the adjacent side are connected to a buffering shaft end of the buffer; the buffer consists of a buffering shaft, a shaft sleeve and a spring; the shaft sleeve is sleeved on the buffering shaft; the spring is sleeved in the shaft sleeve; and one end of the buffering shaft passes through a hole formed on the bottom part of the shaft sleeve, the pretightening force of the end is adjusted by one nut, and then the end is deadly locked by using the other nut. The buffering shaft is provided with a step a, and in the normal state, the step a is positioned in the shaft sleeve; the side supporting roller bracket consists of a cross beam and side supporting rollers hinged at two ends of the cross beam through hinges; one end of the side supporting rollers is connected with the adjacent side supporting roller bracket through movable connecting pieces which consist of threaded pins, spring pads and nuts; and the threaded pins pass through holes on the side supporting roller bracket and then are connected with shaft pins of the adjacent side supporting rollers.
Description
Technical field
The present invention relates to the structure of a kind of structure of impact idler, particularly a kind of novel impact idler.Belong to the mining equiment technical field.
Background technology
The belt transmission is the mine; electric power; the harbour; chemical industry; industries such as metallurgy are used more a kind of load transfer device; mainly constitute with group and load-transfer device by some groups of holders; difference according to use occasion; the band conveyor that has is very long; and form by several sections; adjacent both ends has individual drop; 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; several rubber bumper ring is set on existing carrying roller group and two side rollers; this transformation makes between band and the carrying roller buffering; protection load-transfer device and carrying roller have been played to a certain extent; but facts have proved that this transformation can't fundamentally solve load-transfer device and carrying roller rapid wear problem.
Summary of the invention
Purpose of the present invention is at the problem of above-mentioned existence, provides a kind of effective protection load-transfer device and carrying roller to reduce the structure of a kind of novel impact idler of damaging to greatest extent under the material impact.
For achieving the above object, the technical solution adopted in the present invention is: comprise carrier roller frame, the side roller of middle idler roller and middle idler roller both sides, it is characterized in that the axle at middle idler roller two ends and the axle of an adjacent side carrying roller all are hinged 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, 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, described energy disperser is by buffer shaft, the spring that is nested with in axle sleeve that is nested with on the buffer shaft and the axle sleeve constitutes, after the low hole of the axle sleeve that is fixed on the crossbeam is passed in the lower end of buffer shaft, after the adjusting predetermincd tension is extremely suitable, locked with two nuts.Be fixed with step in the energy disperser on the buffer shaft, step is greater than the following diameter of pressing spring, and less than sleeve diameter, active connection is made of nut, spring chair and the threaded pin that passes the side roller bracket holes, and the pivot pin of an end of threaded pin and side roller one end connects.
Beneficial effect: since the present invention 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; during use under the effect of material; load-transfer device, middle idler roller and two side roller elasticity press down; overcome hard collision; a load-transfer device and a carrying roller have effectively been protected; prolonged service life; reduced productive costs, the present invention is specially adapted to the top of the band conveyor of drop.
