Abstract

The utility model discloses a rolling guiding device of a steel rope guide. The rolling guiding device is composed of a support and two symmetrical rolling assemblies, wherein the rolling assemblies are fixedly arranged on the support. Each rolling assembly has the structure as follows: an inner-end T-shaped loose bush, a middle-end T-shaped loose bush and an outer-end T-shaped loose bush are arranged on one shaft, wherein an inner-end bearing sleeve and an inner-end polyurethane friction plate are sequentially installed on each inner-end bush; a middle polyurethane friction plate is installed on each middle-end bush; an outer-end polyurethane friction plate and an outer-end bearing sleeve are sequentially installed on each outer-end bush. The shaft outer-ends of the two rolling assemblies are provided with a clamp plate, and the two rolling assemblies and the support are tightly pressed by the clamp plate of the shaft outer-ends and nuts to be combined together. The rims of the six polyurethane friction plates are surrounded into a hole for penetrating a guide steel rope. According to the rolling guiding device, sliding friction is changed to rolling friction, abrasion is reduced, fracture is prevented, the service life is long, and the steel rope is not damaged.

Description

The flexible cage guide rolling guide apparatus

Technical field

The utility model relates to the flexible cage guide that the mine shaft construction is used.

Background technology

At present stage mine shaft construction on earth after temporary twisting-changing, all adopt temporary cage to promote, temporary cage adopts flexible cage guide mostly.Flexible cage guide orienting sleeve (sliding sleeve) all adopts slide-and-guide, and the orienting sleeve material is varied, and early stage have a bronze, ferrostell, later stage and be widely used now polyurethane, nylon, plastics and plastics coal ash synthetic material etc.That early stage metal sliding sleeve exists is easy to wear, fracture, accelerate the defect such as steel rope abrasion; Later stage chemical composition sliding sleeve exists resistance to wear poor, and easy fracture, change the defects such as frequent.According to field statistics, within average 2～3 hours, will change once, each cage 8 pair, change and once need 1～1.5 hour, and hanging operation, delays work and mistake, and has a strong impact on construction speed, increases potential safety hazard, and construction cost obviously strengthens.

Summary of the invention

The purpose of this utility model is the above-mentioned deficiency that overcomes existing flexible cage guide sliding type orienting sleeve, and existing orienting sleeve is improved, and designs a kind of roller guide piece.

The technical scheme that the utility model is taked is:

A kind of flexible cage guide rolling guide apparatus, is characterized in that, it is to consist of support and the rolling assembly that is fixed on two symmetries on support; The structure of rolling assembly is, is provided with three T shape loose bushs on an axle, is respectively inner lining, interstage bushing and outer end lining; On inner lining, inner bearing carrier ring and inner polyurethane friction plate are installed successively, inner bearing carrier ring and the sulfuration of inner polyurethane friction plate are bonded to one; The intermediate urethane friction plate is installed on interstage bushing, outer end polyurethane friction plate and outer end bearing carrier ring are installed on the lining of outer end successively, outer end polyurethane friction plate and outer end bearing carrier ring sulfuration are bonded to one; The axle outer end of two rolling assemblies is installed the lastblock clamping plate again, by clamping plate and nut, compresses two rolling assemblies together with holder combination;

Above-mentioned all polyurethane friction plates are round wheel shape, can together with lining, on axle, rotate; Wherein, the wheel rim of two inner polyurethane friction plates is mutually close, the wheel rim of two outer end polyurethane friction plates is mutually close, the thickness of two intermediate urethane friction plates and the diameter of the spacing between wheel rim and guide rope coupling, thus make the wheel rim of above-mentioned six polyurethane friction plates surround a hole that guide rope is passed.

During use, each guide rope only needs two cover guide piecees, a set of cage top cover that is arranged on, and another set of being arranged on cage bottom plate triangular support gets final product, and installs simple and easy.

Below according to principle of work, advantage of the present utility model is described: during cage hoisting, this guide piece produces the rolling directional tagging with flexible cage guide on four direction, makes cliding friction become friction of rolling, wearing and tearing have been reduced, prevent fracture, long service life, do not destroy steel rope.When a certain polyurethane friction plate damages, without whole replacings, and easy accessibility is easily gone while changing; After the wearing and tearing of a certain polyurethane friction plate, can also repeated usage through simple and easy reprocessing; When guiding clearance need to be adjusted, as long as, at inside and outside side bearing cover increase and decrease pad, just can meet " safety regulations in coal mine " requirement to guiding clearance.

The accompanying drawing explanation

Fig. 1 is the constructional drawing that the utility model embodiment overlooks state.

Marginal data, 1-support, the inner bearing carrier ring of 2-, the inner polyurethane friction plate of 3-, the inner lining of 4-, 5-intermediate urethane friction plate, 6-outer end polyurethane friction plate, 7-interstage bushing, 8-outer end bearing carrier ring, 9-clamping plate, 10-outer end lining, 11-axle, 12-hole.

The specific embodiment

Below further illustrate with reference to the accompanying drawings structure of the present utility model.

Flexible cage guide rolling guide apparatus as shown in Figure 1, consist of support 1 and the rolling assembly that is fixed on two symmetries on support 1; The structure of rolling assembly is, is provided with three T shape loose bushs on axle 11, is respectively inner lining 4, interstage bushing 7 and outer end lining 10; On inner lining 4, inner bearing carrier ring 2 and inner polyurethane friction plate 3 are installed successively, inner bearing carrier ring 2 and 3 both sulfurations of inner polyurethane friction plate are bonded to one; Intermediate urethane friction plate 5 is installed on interstage bushing 7; Outer end polyurethane friction plate 6 and outer end bearing carrier ring 8 are installed on outer end lining 10 successively, and outer end polyurethane friction plate 6 and 8 both sulfurations of outer end bearing carrier ring are bonded to one; The axle outer end of two rolling assemblies is installed lastblock clamping plate 9 again, by nut, two rolling assemblies and support 1 is combined; Above-mentioned six polyurethane friction plates 3,5 and 6 are round wheel shape, can together with 10, on axle 11, rotate with lining 4,7 separately; Wherein, wherein, the wheel rim of two inner polyurethane friction plates 3 is mutually close, the wheel rim of two outer end polyurethane friction plates 6 is mutually close, the thickness of two intermediate urethane friction plates 5 and the diameter of the spacing between wheel rim and guide rope coupling, thus make the wheel rim of above-mentioned six polyurethane friction plates surround a hole that guide rope is passed 12.
