Abstract
The invention relates to a conveyor chain tension device, which comprises a chain wheel, a chain and a frame, wherein the chain wheel is fixed on the frame; the chain wheel and the chain are in engaging transmission; a tension device is arranged on an adjusting chain wheel and consists of an adjusting lever, an adjusting nut and an adjusting plate; the adjusting plate is of an L-shape, and the side plate and the bottom plate of the adjusting plate are provided with a round hole respectively; the chain wheel is fixed on the frame through a fastening piece; and the adjusting lever passes through the round hole on the side plate of the adjusting plate and is fixed through the adjusting nut. By using the tension device, the conveyor chain tension device is small in volume and takes small space, the structural form of the chain wheel on the conveyor is not needed to be changed, and only the degree of tightness of the nut is adjusted to ensure that the adjusting lever generates left and right displacement relative to an adjusting lever mounting frame so as to adjust the degree of tightness of the chain, so tension adjustment after chain loosening can be finished through the simple and convenient operation without dismounting a driving chain. The conveyor chain tension device is simple and convenient for operation and fast in speed, and the service life of the chain wheel is increased.
Description
Technical field
The present invention relates to the mechanical transmission mechanism technical field, in particular for the chain stretching device on the chain drive roller conveyor.
Background technology
The chain drive roller conveyor is a kind of common power drum load transfer device, and in the cargo transfer process, the propulsive effort that cylinder is required is mainly by the chain device transmission.Because chain is long, the weight of self is bigger, needs tensioning when chain is installed, chain in use, normal wearing and tearing can make chain extend gradually, cause chain sag to increase gradually, chain produces acutely beats, and chain wear strengthens, even the phenomenon that the jumping tooth occurs, take off tooth, therefore should in time adjust its elasticity, and sprocket wheel and chain and associated components are pinpointed the problems and should be proofreaied and correct at once before and after observing whether on same straight line, exempt future trouble, meet the standard of zero tolerance.
Chain device of the prior art, because of fixing the position of driving wheel and flower wheel, promptly distance between the two is changeless, if chain produces loosening, then need to dismantle chain, shorten the purpose that chain length reaches tension chain by removing the chain unit piece, whole adjustment process not only troublesome poeration, to regulate work capacity big, efficient is low, and can cause the loss of lubricating oil in the process of adjusting.
Summary of the invention
The applicant is at shortcomings such as above-mentioned tightening device complexity of the prior art, adjusting difficulties, a kind of rational in infrastructure, easy to operate conveyor chain tightening device is provided, thereby can prevent that chain from taking off chain, climbing tooth, volume is little, need not change the version of conveyer upper sprocket wheel, the wearing and tearing by tightening device has alleviated sprocket and chain have increased service life.
The technical solution adopted in the present invention is as follows:
A kind of conveyor chain tightening device, comprise sprocket wheel, chain and frame, described sprocket wheel is fixed on the frame, described sprocket wheel and chain pass through engaged transmission, regulate sprocket wheel and be provided with tightening device, described tightening device is made up of adjust bar, setting nut and regulating plate, described regulating plate becomes " L " shape, have circular hole on its side plate and the base plate, and described sprocket wheel is fixed on the frame by fastener with sprocket wheel, described adjust bar passes described regulating plate circular hole that side plate is opened and fixes by setting nut.Its further technical scheme is:
Have a slotted hole on the described frame;
Described adjusting sprocket wheel is installed on the sprocket shaft, and passes slotted hole that frame is opened, described sprocket wheel by bearing fixing on sprocket shaft.
Beneficial effect of the present invention is as follows:
In case the chain of chain gear transmission device takes place loosening, just tightens and is installed in adjust bar upper spider nut outside, make adjust bar promote regulating plate and in the slotted hole of frame, move right, up to the tensioning that realizes chain.By using tightening device, volume is little, occupy little space, do not need to change the version of conveyer upper sprocket wheel, only need to make adjust bar produce left and right displacement with respect to the adjust bar mounting bracket by the degree of tightness of setting nut, thereby realize regulating the degree of tightness of chain, so easy operation can be finished the tensioning adjustment after chain becomes flexible, and need not to carry out the dismounting of driving chain, has easy and simple to handle, speed is fast, increases the service life of sprocket wheel.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As depicted in figs. 1 and 2, conveyor chain tightening device of the present invention comprises sprocket wheel 4, chain 12 and frame 6, see Fig. 3, have a slotted hole 5 and two circular holes 13 on the frame 6, sprocket wheel 4 is fixed on the frame 6 by sprocket shaft 7, sprocket shaft 7 also passes frame 6 slotted hole of opening 5, and sprocket wheel 4 is fixed on the sprocket shaft 7 by bearing 8, sprocket wheel 4 passes through engaged transmission with chain 12, sprocket wheel 4 is provided with tightening device, tightening device is by adjust bar 1, setting nut 2 and regulating plate 3 are formed, and see Fig. 4,3 one-tenth " L " shapes of regulating plate, have circular hole 10 on its side plate 9, have two circular holes 12 on the base plate 11, and with sprocket wheel 4 by bolted connection with base plate 11 be fixed in frame 6 on the slotted hole of opening 5, adjust bar 1 pass regulating plate side plate 9 the circular hole of opening 10 and fix by setting nut.
In the actual use, if the chain 12 in the chain drive takes place when loosening, by tighten setting nut 2 make adjust bar 1 with respect to frame 6 be installed produce displacement to the right (as Fig. 1 arrow right to), thereby the tightening device tensioning chain 12.The present invention only needs to regulate by nut, adjustment to the distance between the sprocket wheel realizes the adjustment of tensioning again that chain is loosening, need not to carry out the dismounting of driving chain, have advantages such as simple to operate, that governing speed is fast, be widely used in the chain drive on the various roller conveyors.
More than describing is explanation of the invention, is not that institute of the present invention restricted portion is referring to claim to the qualification of invention, and under the situation of spirit of the present invention, the present invention can do any type of modification.
