Abstract

The utility model relates to a novel supporting plate and supporting wheel set device for a heavy plate feeder. The novel supporting plate and supporting wheel set device comprises rubber coated supporting wheels, a splint, an erection support, pin rolls and a rotating shaft. A single-wheel structure is changed into a duplex-wheel structure; the outer ring of each wheel is a wear-resistant pressureproof rubber ring instead of steel; two rubber coated supporting wheels into which the pin rolls are inserted are connected with the splint provided with the rotating shaft into a whole. The novel supporting plate and supporting wheel set device is fixed to a main frame of the heavy plate feeder through the erection support, and multi-group configuration is carried out below the supporting plate according to the size of a material receiving part; when the heavy plate feeder works, a material freely falls to the supporting plate, impulse load generated by collision is transferred to the wear-resistant rubber rings on the supporting wheels of a supporting wheel set, and is partially absorbed, and the rest impulse load is transferred to the main frame and absorbed by the main frame structure to fulfill the aims of improving the abrasion condition of the supporting plate and prolonging the service life of the supporting plate.

Description

Heavy-duty plate feeder novel supporting plate holder Wheels group arrangement

Technical field

The utility model relates to a kind of heavy-duty plate feeder novel supporting plate holder Wheels group arrangement, belongs to mechanical field.

Background technology

At present; in heavy-duty plate feeder manufacturing; the supporting plate being shaped by Plate Welding is connected to form one group of flexible structure with bolt and roller; in operational process because polygon effect supporting plate operational process is up-down vibration operation; all support rollers and rail all leave certain distance with supporting plate; material directly drops on heavy-duty plate feeder from feed bin; material is sizable to the impulsive force of supporting plate; under the effect of the impact load under material impact; the supporting plate frequent deformation of apron feeder; easily make supporting plate, tie bolt fracture, cause shutdown maintenance.At present both at home and abroad the supporting plate support roller of producer is all designed to the multi-point support of single-wheel pattern, have certain effect, but effect is still undesirable for the processing of the problems referred to above.

Utility model content

For above-mentioned deficiency; the utility model provides a kind of heavy-duty plate feeder novel supporting plate holder Wheels group arrangement; be intended to solve current production heavy-duty plate feeder often because supporting plate distortion causes tie bolt and supporting plate distortion or rupture causing the problem of shutdown, thus the economic loss that minimizing operating cost and disorderly closedown bring.With duplex riding wheel apparatus, substitute traditional monocycly riding wheel apparatus, can slow down material the impulsive force of supporting plate, actv. are overcome the polygon effect of roller chain wheel, more can realize multi-point support, extend the service life of supporting plate and bolt, and can be widely used in manufacture and the use of various large and medium-sized apron feeders.

The utility model has solved and has filled up technology and the Cost Problems of heavy-duty plate feeder on heavy-duty is manufactured, the technical scheme adopting is: a kind of heavy-duty plate feeder novel supporting plate holder Wheels group arrangement, comprise and cover glue support roller, clamping plate, erection support, bearing pin and rotating shaft, by single-wheel structure, change double linked wheel structure into, the outer ring of wheel is made wear-resisting pressure-resistant rubber circle into by steel part, by two penetrate bearing pin cover glue support roller, with the clamping plate with rotating shaft, be connected; This novel supporting plate holder Wheels group arrangement is fixed on erection support on the main frame of heavy-duty plate feeder, carries out many assembly put according to the size of material feeding place below supporting plate.When heavy-duty plate feeder is worked, material free fall is to supporting plate, the impact load that collision produces is first passed to the antifriction rubber circle on the support roller of support roller group, after partially absorbing, more remaining impact load is delivered to main frame, by main frame structure, absorbed, reach the wear pattern that improves supporting plate, the object that extends the service life of supporting plate.

The beneficial effects of the utility model are: compare with traditional single-wheel structure that mechanical noise is little, long service life, can save higher maintenance cost, be more suitable for the Design and manufacture of heavy super wide-plate feeder, can meet that Coal Industry is intensive simultaneously, the high request in high strength exploitation, greatly raise labour productivity, save investment, reduce production costs.

Accompanying drawing explanation

Fig. 1 is scheme of installation of the present utility model.

Fig. 2 is the shaft side figure of the utility model structure.

Fig. 3 is the complete section figure of support roller combination.

Mark in figure: 1 tie bolt, 2 chain rails, 3 supporting plates, 4 buffer rails, 5 support roller groups, 6 clamping plate, 7 cover glue support roller, 8 erection supports, 9 rotating shafts, 10 antifriction rubber layers, 11 back-up rings, 12 locking spring circles, 13 flat gaskets, 14 spring washers, 15 nuts, 16 core wheels, 17 bearings, 18 dustproof axle sleeves, 19 bearing pins.

The specific embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.

The utility model device is comprised of with clamping plate (6) and erection support (8) two glue support rollers (7) that cover with antifriction rubber circle, forms two-wheeled supporting plate wheels (5), then is arranged on and on organism frame, forms the device that one group of support roller can rotate up and down.Feeder is when convey materials, by support roller group (5), carry out Multipoint weighting, flexible supporting plate combination is played under the impulsive force of material to buffer action and by its force transmission to main frame, actv. reduces supporting plate (3) deflection in use, improve the wear pattern of supporting plate (3), extend supporting plate (3) and tie bolt (1) service life.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.

Claims (1)

1. a heavy-duty plate feeder novel supporting plate holder Wheels group arrangement, comprise and cover glue support roller, clamping plate, erection support, bearing pin and rotating shaft, by single-wheel structure, change double linked wheel structure into, the outer ring of wheel is made wear-resisting pressure-resistant rubber circle into by steel part, by two penetrate bearing pin cover glue support roller, with the clamping plate with rotating shaft, be connected; This novel supporting plate holder Wheels group arrangement is fixed on erection support on the main frame of heavy-duty plate feeder, carries out many assembly put according to the size of material feeding place below supporting plate.
