Abstract

The utility model discloses a roller cage shoe which is arranged on a vertical shaft hoisting conveyance (cage conductor or skip bucket). The roller cage shoe comprises a support, a swing frame, a composite buffer, a roller assembly and the like. The swing frame and the composite buffer form a triangle movable support structure. The support and the swing frame, the swing and the composite buffer, and the composite buffer and the support are all connected through pin shafts. The pin shafts are semi-floating connecting structures. A polyurethane wheel and a wheel rim are casted into together and fixed on a wheel hub. The wheel hub is fixed on the swing frame through a wheel shaft. Compared with the prior art, the roller cage shoe has the advantages that a cage guide is not damaged, running is safe; whole stability is strong, balance is good; the hollow structure of the wheel rim is beneficial to air circulation, heat dissipation performance is good, appearance is attractive; the roller cage shoe cannot easily sway due to the fact that the pin shafts adopt the semi-floating structures; noise is avoided due to the fact that abrasion resistant linings can be filled with lubricating grease; service life is long, and economical efficiency is good.

Description

Rolling cage shoe

Technical field:

The utility model relates generally to the rolling cage shoe that the mine hoisting container is used, and is specifically related to the rolling cage shoe on lifting mine cage for coal mine shaft or skip bucket.

Background technology:

Coal is the important energy source of China.In the process of coal mining, lifting container important role, particularly vertical cage play the throat effect to going into the well on personnel and material, and skip bucket is the visual plant that coal promotes.Lifting container (cage or skip bucket) must have the rolling cage shoe orbiting when moving up and down, for container provides guiding and buffering.

Existing rolling cage shoe wheel hub and polyurethane wheel are split-type structurals, the one, and the dismounting trouble, the 2nd, when the roller running was bad, in the situation that frictional heat, polyurethane wheel heat absorption distortion separated with wheel hub, damages cage guide, causes safety misadventure.Existing rolling cage shoe bearing and rocker, between rocker and composite buffering device, composite buffering device and bearing, for the full-floating bearing pin is connected, the looseness of easily wearing and tearing produces noise and also damages cage guide.Existing rolling cage shoe is short service life, less economical.

The utility model content:

The purpose of this utility model is, overcomes the deficiency of existing form, and a kind of safe, rolling cage shoe of saving, operating steadily is provided.It has simultaneously: 1, simple in structure; 2, easy for installation; 3, do not damage cage guide; 4, the life-span long, maintenance capacity is few; 5 are active in one's movements, the characteristics such as reliable operation.

The utility model is realized in the following manner: together with wheel rim was cast in, wheel rim was fixed on wheel hub the polyurethane wheel.Rolling cage shoe bearing and rocker, between rocker and composite buffering device, composite buffering device and bearing, for the semi-floating bearing pin is connected, movable position adds anti-wearing liner.

The preferred version of such scheme is, comprises the polyurethane wheel together with wheel rim is cast in, and wheel rim is made engraved structure, and wheel rim is fixed on wheel hub.

Another preferred version of such scheme is, also comprises two kinds of semi-floating structures of connecting link pin, and a kind of two ends are fixed, and the centre adds the semi-floating structure that anti-wearing liner rotates; Interference fit in the middle of another kind of, two ends add the semi-floating structure that anti-wearing liner rotates.

Compared with prior art the utility model has following advantage: do not damage cage guide, safe in operation; Resistance to overturning is strong; Balance is good; Can not fall wheel; The favourable circulating air of the engraved structure of wheel rim, thermal diffusivity is good, and is handsome in appearance; Bearing pin connects employing semi-floating structure and is difficult for spacious moving; Anti-wearing liner can grease up, noiselessness; Long service life, good economy performance.

Description of drawings:

Fig. 1 is the structural representation of rolling cage shoe described in the utility model.

In figure, 1-polyurethane wheel, 2-wheel rim, 3-wheel hub, 4-bearing pin one, 5-composite buffering device, 6-bearing pin two, 7-bearing, 8-bearing pin three, 9-rocker, 10-wheel shaft.

The specific embodiment:

Below in conjunction with description of drawings and the specific embodiment, the utility model is described in further detail: rolling cage shoe as shown in Figure 1, its structure are bearing (7), rocker (9), composite buffering device (5), roller assembly (comprising the combination of 1-polyurethane wheel, 2-wheel rim, 3-wheel hub, 10-wheel shaft) etc.Bearing, rocker and composite buffering device consist of the triangle movement support structures, bearing connects by bearing pin (8) with rocker, rocker connects by bearing pin (4) with the composite buffering device, and the composite buffering device connects by bearing pin (6) with bearing, and the roller assembly connects with rocker by wheel shaft.

Rolling cage shoe of the present utility model, together with wheel rim was cast in, wheel rim was fixed on wheel hub polyurethane wheel, wheel hub is fixed on rocker by wheel shaft, and from inside to outside successively limit mounting can prevent wheel.Bearing and rocker, between rocker and composite buffering device, composite buffering device and bearing, for the semi-floating bearing pin is connected, movable position adds anti-wearing liner.Have point of attachment and can not produce abnormal sound and looseness, long service life, economy is high.

In a word, the utility model provides a kind of rolling cage shoe of optimizing structure.The above is only a part of specific embodiment of the present utility model.Protection domain of the present utility model is not limited to this, anyly is familiar with those skilled in the art in the technical scope that the utility model discloses, and the variation that can expect easily or replacement are within all should being encompassed in protection domain of the present utility model.

Claims

1. the rolling cage shoe on a lifting mine cage for coal mine shaft or skip bucket, comprise the polyurethane wheel together with wheel rim is cast in, and it is characterized by: wheel rim is made engraved structure, and wheel rim is fixed on wheel hub, and wheel hub is fixed on rocker by wheel shaft; Bearing, rocker and composite buffering device consist of the triangle movement support structures, and bearing connects by bearing pin with bearing with composite buffering device, composite buffering device with rocker, rocker, and its bearing pin is the semi-floating draw bail.
