Abstract
A lifting machine comprises an adjusting slider, a slideway matching the adjusting slider, an adjusting screw set on the adjusting slider, a driving shaft, a driven shaft, a conveyer chain surrounding the driving shaft and the driven shaft, a guide hub on the driven shaft and in transmission connection with the conveyer chain, and a tensioner used for adjusting the tension of the conveyer chain and ensuring good contact and transmission between the guide hub and the conveyer chain. The guide hub plays a role of guide and has a circular structure, and the contact face of the guide hub and the conveyer chain is a plane. The problem that the top of chain wheel contacts the conveyer chain is solved. In harsh environment, when the conveyer chain is lengthened, the tensioner on the driven shaft can ensure the contact of the guide hub and the conveyer chain.
Description
Technical field
The utility model relates to a kind of load transfer device of vertical-lift goods, is specifically related to a kind of gig that is applicable to article such as grain, fruits and vegetables, feed.
Background technology
Vertical elevator is widely used in a plurality of fields such as chemical industry, metallurgy, light industry as a kind of elevating gear; Gig driven shaft and tightening device principle of work: gig is a vertical frame sprocket wheel structure for conveying; Vertical frame prevents material from leakage, and material inlet is in the bottom, and outlet is on top.The top imput shaft drives chain (hopper is housed on the chain), and hopper is equipped with material, through the chain transmission, rises to top to material from the bottom.Chain is in operation process, and is general long owing to chain, departs from the running orientation for preventing conveyer chain, and the bottom is equipped with driven shaft, plays the chain directional tagging.Be designed to jockey sprocket on the general gig driven shaft and do directional tagging.At normal temperatures or chain not under the wear pattern, the jockey sprocket on the driven shaft can play directional tagging.But because operating ambient temperature is high, chain expands with heat and contract with cold, or under the chain wear pattern, chain is elongated, and the jockey sprocket on the moving axis also is fixed on the home position.When arriving to a certain degree, cause: 1, chain is pushed up on the jockey sprocket top, breaks chain; 2, the wearing and tearing of jockey sprocket and chain are asynchronous, cause jockey sprocket and chain that stuck phenomenon is arranged; 3, the jockey sprocket top is separated from chain, and jockey sprocket does not play the guiding role.The appearance of the problems referred to above will directly influence the normal operation of gig.
Summary of the invention
Deficiency to the prior art existence; The utility model technical matters to be solved is, the gig of a kind of simple in structure, in operational process, effectively play the guiding role for driven shaft and guarantee to lead wheel hub and the good contact matching of chain are provided, enhancing productivity.
For solving the problems of the technologies described above; The technical scheme that the utility model is taked is: a kind of gig; Comprise the adjustment slide block, with the chute that cooperates of adjustment slide block, be located at the adjustment screw rod adjusted on the slide block, imput shaft, driven shaft and around the chain of said imput shaft and driven shaft; It is characterized in that: also comprise the guiding wheel hub of being located on the driven shaft; Said chain is in transmission connection with the guiding wheel hub, and the tightening device that is used to adjust the chain tensioning degree, guarantees guiding wheel hub and the good contact matching transmission of chain.
Above-mentioned gig; Said tightening device by spring, spring stop piece, standing screw, and the tensioning setting nut form; Spring stop piece be located on the adjustment screw rod and with adjustment screw rod bearing fit; Both sides at the adjustment screw rod are respectively arranged with and spring stop piece bonded assembly standing screw, and said tensioning setting nut is located on the standing screw and with spring stop piece and is fixed, and said spring is located between spring stop piece and the adjustment slide block.
Above-mentioned gig, said guiding wheel hub is set to circular configuration, captives joint with driven shaft through the back-up ring at key and two ends.
Above-mentioned gig, said tightening device are located at respectively on the adjustment screw rod at gig two ends.
The advantage of the utility model gig is: the wheel hub that on the gig driven shaft, is designed to lead is done directional tagging, and on driven shaft, tightening device is housed.The guiding wheel hub is a circular configuration, with the chain contact surface be the plane, the problem that chain is pushed up on no sprocket wheel top.And high at operating ambient temperature, chain expands with heat and contract with cold, or under the chain wear pattern; When chain is elongated; Tightening device is housed on the driven shaft can guarantees that the guiding wheel hub on the moving axis contacts with chain, guaranteed gig high temperature, expand with heat and contract with cold and chain worn-down situation under, the guiding wheel hub on its driven shaft still can rationally cooperate with chain; Enhance productivity, reduce error rate.

The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is explained further details;
Like Fig. 1,2,3, shown in 4; A kind of gig; Comprise adjustment slide block 1, with the chute 2 that cooperates of adjustment slide block 1, be located at adjustment screw rod 3 on the adjustment slide block 1, imput shaft 4, driven shaft 5 and, also comprise the guiding wheel hub of being located on the driven shaft 57 around the chain 6 of imput shaft 4 and driven shaft 5, the chain 6 and the wheel hub 7 that leads are in transmission connection; Guiding wheel hub 7 is set to circular configuration, captives joint with driven shaft 5 through the back-up ring 9 at key 8 and two ends.And the tightening device 10 that is used to adjust chain 6 tensioning degrees, assurance guiding wheel hub 7 and chain 6 good contact matching transmissions.Tightening device 10 by spring 11, spring stop piece 12, standing screw 13, and tensioning setting nut 14 form; Spring stop piece 12 be located on the adjustment screw rod 3 and with adjustment screw rod 3 bearing fits; Both sides at adjustment screw rod 3 are respectively arranged with and spring stop piece 12 bonded assembly standing screws 13; Tensioning setting nut 14 is located on the standing screw 13 and with spring stop piece 12 and is fixed, and spring 11 is located between spring stop piece 12 and the adjustment slide block 1, and this tightening device 10 is located at respectively on the adjustment screw rod 3 at gig two ends.
Certainly, above-mentioned explanation is not to be limitation of the present invention, and the present invention also is not limited to above-mentioned giving an example; Those skilled in the art; In essential scope of the present invention, the variation of making, remodeling, interpolation or replacement all should belong to protection scope of the present invention.
