Abstract

The utility model relates to a device for unloading coal from a train, in particular to a gate-type chain bucket unloader. The gate-type chain bucket unloader mainly aims to solve the problem that after a chain of an existing gate-type chain bucket unloader becomes loose, the chain needs to be replaced by a new one. The gate-type chain bucket unloader comprises a support, walking wheels, a belt conveyor, a lifting motor reducing gear and a cross beam. A coal lifting unloading mechanism comprises a lifting frame, a driving sprocket, a driving shaft, a motor reducing gear, a driven sprocket, a driven shaft, a chain, chain buckets, pulleys and a steel rope. Two sliding blocks are fixed to the two ends of the driven shaft respectively. The sliding blocks are respectively provided with a through hole. Two lead screws penetrate through the through holes of the two sliding blocks respectively. The lower end of each lead screw extends out from the bottom of the lifting frame. A blind nut is arranged on the extending-out portion of each lead screw. The upper end of each lead screw is provided with a nut. Each lead screw is sleeved with a spring. The upper end of each spring abuts against the corresponding nut. The lower end of each spring abuts against the corresponding sliding block. The gate-type chain bucket unloader has the advantage of being capable of guaranteeing that the chain makes tight contact with the driven shaft all the time.

Description

Gate-type unloading machine with chain buckets

Technical field:

The utility model relates to a kind of device of unloading coal from train.

Background technology:

Existing gate-type unloading machine with chain buckets comprises support, road wheel is arranged at the bottom of support, movable motor reductor is fixed on support, sprocket wheel on movable motor braking maneuver power output shaft is connected by chain with the sprocket wheel on road wheel, crossbeam is fixed on the top of support, band conveyor is contained on crossbeam, lifting motor reductor is fixed on crossbeam, the lifting mechanism of unloading coal comprises raising legs, drive sprocket is contained in imput shaft, imput shaft is contained in the top of raising legs by bearing, the top of raising legs is also fixed with motor reducer, the power take-off shaft of motor reducer is connected with coupler with imput shaft, driven axle is arranged at the bottom of raising legs, by movable sprocket, be contained on driven axle, chain is contained in drive sprocket and by movable sprocket, on chain, be fixed with several chain buckets, pulley is contained in the bottom of raising legs by axle, steel cable one end is fixed on pulley, the other end is wrapped on the reel on lifting motor braking maneuver power output shaft, during work, road wheel walking, raising legs is positioned at and is equipped with above the railway carriage of coal, motor reducer work, drive sprocket rotates and drives chain bucket motion, coal is transported on band conveyor, band conveyor is transported to coal yard by coal, when coal reduces, the work of lifting motor reductor, to transferring lift system, chain bucket is contacted with coal, continue to unload.But the shortcoming of this gate-type hopper car unloader is that, after work a period of time chain fluffs, the chain that need more renew, both wasted time and energy, and delayed again production, had also increased the cost of unloading.

Summary of the invention:

Technical problem to be solved in the utility model is to provide a kind of chain that need not more renew after chain fluffs, and can guarantee to produce the gate-type unloading machine with chain buckets normally carrying out.

Above-mentioned purpose is achieved in that same as the prior art is that it also comprises support, road wheel is arranged at the bottom of support, movable motor reductor is fixed on support, sprocket wheel on movable motor braking maneuver power output shaft is connected by chain with the sprocket wheel on road wheel, crossbeam is fixed on the top of support, band conveyor is contained on crossbeam, lifting motor reductor is fixed on crossbeam, the lifting mechanism of unloading coal comprises raising legs, drive sprocket is contained in imput shaft, imput shaft is contained in the top of raising legs by bearing, the top of raising legs is also fixed with motor reducer, the power take-off shaft of motor reducer is connected with coupler with imput shaft, driven axle is arranged at the bottom of raising legs, by movable sprocket, be contained on driven axle, chain is contained in drive sprocket and by movable sprocket, on chain, be fixed with several chain buckets, pulley is contained in the bottom of raising legs by axle, steel cable one end is fixed on pulley, the other end is wrapped on the reel on lifting motor braking maneuver power output shaft, difference is: the two ends of driven axle are all fixed with slide block, on two slide blocks, there is through hole, two screw mandrels pass respectively from the through hole of two slide blocks, all stretch out from the bottom of raising legs the lower end of two screw mandrels, on sponson, have nut, there is nut the upper end of two screw mandrels, on two screw mandrels, all overlaps and has spring, the upper end of spring withstands on nut, and the lower end of spring withstands on slide block.

The utility model has the advantages that: during installation, make spring in impaction state, because slide block is established at the two ends at driven axle, on the screw mandrel of slide block top, cover has spring, so after work a period of time chain-loose, under the effect of spring force, driven axle moves down, by chain tightens, and without changing chain, time saving and energy saving, reduce unloading charges use, can guarantee to produce and normally carry out.Until when spring flicks completely, can also adjust the nut at spring top, make nut continue holddown spring, thereby guarantee chain all the time with driven axle close contact.
