Description

Ring chain plate type conveyer

The utility model is a kind of Plate Conveyor with loop chain, and it is applicable to the lump material of carrying cement and industries such as mine, metallurgy.

Chinese patent has been announced a kind of " Plate Conveyor with loop chain " 88216280, No. 2: its structure is by head, centre and afterbody frame, transmission, changed course chain wheel set, flexible carrier (comprising loop chain, " U " type bolt and dissepiment part), upper and lower support roller group, and spiral tensioning device is formed; Its objective is provides a kind of " high reliability, flexible, simple novel conveyer of processing technology " that is applicable to industries such as mine, building materials, metallurgy.The loop chain of the conduct traction that this conveyer adopted is the bottom that is positioned at dissepiment.When dissepiment was in the upper strata, loop chain fell in the pop-up race, and last support roller holds up dissepiment; But when dissepiment ran to lower floor, loop chain then was in the top of dissepiment and can't falls in the subiculum race (because between loop chain and the lower support wheel across one deck dissepiment).Owing to exist above-mentioned unreasonable place on the structure, institute causes lower floor's dissepiment wigwag motion, bob so that lower floor's loop chain loses jacking and orbit, and the complete machine operation is not steady, noise is big and wearing and tearing are accelerated thereby make.

The purpose of this utility model is to provide a kind of Plate Conveyor with loop chain, and it can overcome defective of the prior art effectively, and, in the harsh environment of high temperature and many dust, can fully show its great vitality.

The purpose of this utility model is achieved in that on the frame of its head and centre and afterbody, power wheel device and upper and lower riding wheel apparatus and follower device, tightening device are housed respectively, between transmission, follower device, be wound with traction component, wherein, in the described traction component, be that two loop chains are separately positioned on both sides under the dissepiment, and the both sides of every block of dissepiment are welded with angle bar, bail penetrates angle bar, and is fastening with nut, and dissepiment and loop chain are fused.

In above-mentioned transmission, follower device, their wheel rim is fixed on the wheel hub with bolt after can becoming whole wheel rim by bolted connection by two and half wheel rims again.

Above-mentioned tightening device, in the dovetail slide block of passive wheel shaft can being packed into, again with clamp with it is stuck (it is rotatable that antifriction-bearing box is housed on the follower); Article one, on slide block, the other end of rope has hung clump weight to steel rope by pulley system.

Principle of work of the present utility model is: utilize the downward gravity of the clump weight in the tightening device, traction component is stretching, tension.Under the effect of this gravity, be enough to overcome traction component and be transferred under the situation of material weight summation when the friction force between power wheel and the loop chain reaches, this machine is entry into service.

Advantage of the present utility model is:

One, operate steadily, safe and reliable: this is because change loop chain into the both sides of dissepiment and the result who has adopted the counter weight type tightening device to be brought by the bottom of dissepiment.

Two, owing to adopted above-mentioned up-to-date technology and adopted removable jew master, follower structure, thus not only make simple, installation and maintenance are convenient and investment, service expenditure are low, and long service life.

Three, again owing to adopted above-mentioned improvement structure and lubricating point few, so enduring is strong, range of use is wide, and can be in the big harsh environment of high temperature and dust normal operation.

Fig. 2 is the structural representation of power wheel device 1 and traction component 6 among Fig. 1;

Fig. 3 is A among Fig. 1---the A cutaway view;

Fig. 4 is B among Fig. 3---the B cutaway view;

Fig. 5 is the structural representation of tightening device 9 among Fig. 1.

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing thereof:

Fig. 1 has shown the mutual alignment relation of each parts of this machine.The supporting device of this machine is made up of head, centre and afterbody frame 2,3 and 7.Power wheel device 1 is housed on the head frame 2, upper and lower riding wheel apparatus 4,5 is housed respectively on the intermediate stand 3, follower device 8 and tightening device 9 are housed on the afterbody frame 7.Be wound with end to end traction component 6 between power wheel device 1 and the follower device 8.Upper and lower layer traction component in the centre portion held up by upper and lower support roller respectively.By the enough friction force that produced between power wheel and the loop chain, make this machine circulating motion.

This machine can be made level and inclination convey materials, and maximum permission inclination alpha is 25 °, and delivered length can reach 70-80 rice.

Fig. 2 has shown the relation between power wheel device 1 and the traction component 6.For the ease of installation, maintenance, power wheel device 1 and follower device 8 all adopt removable jew: be about to two and half wheel rim 1c and connect into a whole wheel rim by bolt 1e, whole wheel rim is connected on the wheel hub 1b with bolt 1d again.The wheel hub 1b of power wheel is fixed on the transmission shaft 1a with flat key.In the wheel hub 1b of follower antifriction-bearing box is housed, passive wheel rim can freely be turned round around driven axle.

As shown in Figure 3, form upper and lower two-layer track, then operation (referring to Fig. 4) in this track of the loop chain 6c that dissepiment 6a is two by several upper and lower riding wheel apparatus 4,5.Have only loop chain is placed the dissepiment both sides, just can avoid the defective of aforementioned middle prior art.The same with prior art, the structure of upper and lower riding wheel apparatus 4,5 is identical, forms by bearing seat 4a, support roller 4b, supporting-roller shaft 4c.

Fig. 4 has shown the structure situation of traction component 6: it is made up of parts such as dissepiment 6a, angle bar 6b, loop chain 6c and bail 6d.Increased angle bar 6b(that weldering with it connects in the both sides of dissepiment 6a referring to Fig. 3), be guarantee that loop chain 6c places the key of dissepiment 6a both sides.

Tightening device 9 as shown in Figure 5, its annexation is: passive wheel shaft 9f packs among the dovetail slide block 9d, use clamp 9e that passive wheel shaft 9f and slide block 9d is stuck again, steel rope 9a penetrates in the hole of slide block 9d by two pulley 9b, and with chuck this end is clipped, the other end of steel rope 9a has hung a clump weight 10.Slide block 9d is contained in the slideway, can move forward and backward.Bilge logs 9c can dismantle, and its available bolt 9g is fixed on the afterbody frame 7.
