Abstract

The utility model discloses an assembly ground roller, which comprises an end cap, a tube body and a supporting shaft. The supporting shaft crosses through the tube body which is covered with bushing on the external surface and the end cap is fixed on both ends of tube body by the restrict equipment. The bushing is between end caps and is clamped closely by end taps. The utility model is characterized in simple structure and easy dismantling, and the utility model also can prolong the overall operation life effectively and protect the assembly ground roller of the steel cable.

Description

Compound type ground roller

Technical field

The utility model is mainly concerned with mine rail transportation and assistant conveyance field, refers in particular to a kind of compound type ground roller that is applied to mine rail transportation or assistant conveyance.

Background technology

In the prior art, in mine rail transportation and assistant conveyance field, matching used ground roller generally adopts one-piece construction in the Transport Machinery such as winch, gig, referring to shown in Figure 3, it mainly comprises body 2 and end cap 1, and body 2 is steel pipe or cast tube, and end cap 1 directly is fastened in the two ends of body 2, its objective is and hold steel rope, guarantee the smooth back and forth movement of steel rope.Contact portion is steel and steel in this structure, steel rope is worn easily, therefore after having used a period of time, influences such as the friction force that is produced in the course of the work at steel rope, impulsive force, make body 2 and steel rope all can be subjected in various degree damage, particularly after body 2 has local area damaged formation wedge angle or burr, just accelerated the rate of wear of steel rope more, shortened the service life of the whole and steel rope of ground roller, just caused after the time of using one section short-term must be in time over the ground roller carry out integral replacing.

The utility model content

The technical problems to be solved in the utility model just is: at the technical matters that prior art exists, the utility model provides a kind of dismounting simple in structure, easy, can effectively prolong whole service life and can protect the compound type ground roller of steel rope.

In order to solve the problems of the technologies described above, the solution that the utility model proposes is: a kind of compound type ground roller, it comprises end cap, body and bolster, bolster is arranged in the body, it is characterized in that: be arranged with lining on the outside face of body, end cap is fixed in the two ends of body by inhibiting device, and the lining that is sheathed on outer surface of tube body clamps between the end cap at body two ends and by end cap.

Described lining is the compound type lining, and it is combined by 4～6 relatively independent linings.

Described lining is made by High molecular material.

Compared with prior art, advantage of the present utility model is:

1, is arranged with the lining made from High molecular material on the outer surface of tube body of the utility model compound type ground roller, thereby make this compound type ground roller in use steel rope can direct contact to body, but contact with lining, in addition the lining material soft, wear-resisting acidproof, be difficult for getting rusty, therefore not only can protect steel rope effectively, further prolong the service life of ground roller;

2, the end cap of the utility model compound type ground roller is anchored on the two ends of body by inhibiting device, during use, the bearing that is used for fixing bolster can at both ends covers direct bore hole and forms, and has saved other annexes such as bearing seat, seal ring, therefore makes roller whole mounting or dismounting in ground get up more easy;

3, the lining of the utility model compound type ground roller adopts the compound type bush structure, formed by the individual independently bush structure of 4-6, can be changed the position mutually, in case localized wear's serious situation occurred, do not need to change whole lining yet, therefore saved maintenance and maintenance cost widely; The arbitrary part of roll structure all can be pulled down fast, dismantle convenient.

The specific embodiment

Below with reference to the drawings and specific embodiments the utility model is described in further details.

As depicted in figs. 1 and 2, compound type of the present utility model ground roller mainly comprises end cap 1, body 2 and bolster 5, bolster 5 is arranged in the body 2, body 2 can adopt steel pipe or cast tube, be arranged with lining 3 on the outside face of body 2, end cap 1 is fixed in the two ends of body 2 by inhibiting device, and lining 3 clamps between the end cap 1 at body 2 two ends and by end cap 1.In the present embodiment, two end caps 1 can lock onto on the two ends of body 2 by bolt 4, and lining 3 is located in wherein tightly.During use, be used for fixing the bearing of bolster 5 can at both ends on the lid 1 directly bore hole form, saved other annexes such as bearing seat, seal ring, mounting or dismounting are got up more easy.This lining 3 is made by High molecular material, has characteristics such as quality is soft, wear-resisting, and in use, steel rope directly contacts with lining 3, so this lining 3 not only played the effect of protection body 2, also further plays the effect of protection steel rope.In preferred embodiment, this lining 3 can adopt the combination lining, this combination lining is made up of the individual independently lining 3 of 4-6, this 4-6 can form when independently lining 3 aggregate erections are used on the outside face that integral body is sheathed on body 2, and all right switch mutually, like this, in case localized wear's serious situation occurred, do not need to change whole lining 3 yet, therefore saved maintenance and maintenance cost widely.
