Abstract

The utility model provides a round pipe type multipurpose cage guide. Multi-section short cage guides with the length of 10-12 meters are welded to be the utility model, and the joints have no gaps. The utility model is arranged along a vertical shaft. A pipe type cage guide is welded with ribbed slabs and connecting plates. A buntons is welded with angle irons. The connecting plates and the angle irons are connected by bolts, and the cage guide is fixed on the buntons by the bolts. A hoisting container can safely, quickly and smoothly run along the long cage guide without the gaps. The section of the round pipe type cage guide has a reasonable force. The cage guide can be doubled as a pipeline, the layout of the cage guide is simplified, lots of steel is saved, the ventilation resistance in a pit shaft can be reduced, and the ventilation effect is enhanced. The utility model is a novel vertical pit shaft cage guide with exploiting prospect.

Description

Round pipe type multipurpose vertical pit shaft cage guide

The utility model relates to a kind of stable operation device of vertical shaft hoisting container, and especially a kind of pit shaft belongs to the shaft of vertical well equipment with the rigidity guide rail of tubular type.

In prior art, the rigidity pit guide of China's mine vertical single-rope hoisting adopts rectangle timber guide and rail guide mostly, and it is only applicable in the less shaft of vertical well of well depth; Along with the development and the shaft of vertical well of technology are deepened gradually, adopt multi rope winding, hoisting container is characteristics with heavy duty, high-speed cruising, variation has also taken place in the cage guide function in the pit shaft, it is except playing the guiding role, the horizontal force load that produces when also being mainly used to resist hoisting container and in pit shaft, moving, thereby adopt side rigidity and the big square-section hollow steel cage guide of section factor, replaced side rigidity and section factor little rail guide and timber guide.The square-section hollow rigid cage guide that China adopts at present mainly contains the cage guide that forms and be welded into band steel with the channel-section steel Combination Welding, see that " shaft of vertical well equipment " history is born, Coal Industry Press's in November, 83 and the vertical compound material guide of developing recently, the patent No. 93236592.2 is steel one glass fiber reinforced plastics composite material rectangle hollow cage guides; Because above-mentioned rectangular cross section steel guide all is short-track installation, being installed in every long 10～12 meters long cage guides along the full deep layer spacing of pit shaft is on the jar beam or carriage of 4 or 6 meters settings, the 4mm shrinkage joint is stayed in the joint, hoisting container is along the rhythmical swing operation of the long cage guide that the shrinkage joint is arranged like this, its supporting capacity all directions are inconsistent, influenced the steadily operation fast of hoisting container, so these cage guide cross section structure forms are not quite reasonable, it makes trouble, and can't eliminate fully because of the distortion that welding causes, influences the installation quality and the result of use thereof of shaft equipment, and the cage guide purposes is single, cause wellbore arrangement crowded, increase flowing resistance, influence the ventilation effect of deep-well.Though the vertical compound material guide is wear-resisting, corrosion-resistant, need special manufacturer's processing, the steel core of welding also causes distortion easily, and procedure is too much, and cost is higher.

The purpose of this utility model is to design a kind of ability unanimity that makes cage guide bear each horizontal direction for the weak point that overcomes above-mentioned prior art existence, simplify the tubular cage guide that shaft section is arranged, the no shrinkage joint of welding between its joint, hoisting container operates steadily, but tubular type pit guide double as pit shaft pipeline.

Task of the present utility model is implemented as follows, a kind of rigidity tubular type multipurpose vertical well shaft cage guide that is applicable to vertical shaft hoisting, and it comprises on jar beam and is welded with angle steel that a jar beam is a rectangle hollow steel guide beam; It comprises that also cage guide is the short cage guide of tubular type, and its two ends is welded with gusset and junction plate, and the tubular type rigid cage guide is to be welded into along the complete dark long cage guide of pit shaft by many short cage guides, and it is fastened on junction plate and angle steel on the jar beam of pit shaft by bolt.

Described long cage guide is that the short cage guide by 10～12 meters of more pieces welds, and the shrinkage joint is not stayed in its joint.

The utility model compared with prior art has the following advantages: this tubular type cage guide is in all directions mechanical property unanimity of hoisting container side in service, and the cross section is stressed rationally, to guarantee hoisting container operation fast along gapless long cage guide safety and steady ground; But it also double as pit shaft pipeline (as water pipe, tracheae etc.) can reduce wellbore tubular way amount (pit shaft can reduce pipe 4 times), thereby save the pit shaft rolled steel dosage significantly, simplify shaft section and arrange, reduce the pit shaft flowing resistance, improve the ventilation effect of deep-well.It is a kind of novel cage guide of promoting future that has.

Fig. 2 is the lateral view of structure chart of the present utility model.

Fig. 3 is the vertical view of structure chart of the present utility model.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail, it is made up of cage guide 1, junction plate 2, gusset 3, jar beam 4, angle steel 5 and bolt 6 etc.; Cage guide 1 is that round seamless steel pipe is made, and connects the long cage guide that forms by many 10～12 meters short cage guides 1 along the full deep welding of pit shaft, and the shrinkage joint is not stayed in the joint of its welding; Junction plate 2 is rectangle steel plates, there is circular hole at two on it, it and cage guide 1 and gusset 3 welding, gusset 3 is rectangle steel plates, its face down bonding is in cage guide 1 two, opposite side is welded on the junction plate 2, and a jar beam 4 is that the cross section is the hollow buntons of rectangle, and it is fixed in the pit shaft every 4～6 meters one entirely deeply along pit shaft; Angle steel 5 is one section common angle steel, and there is circular hole at two on it, and the one wing and 4 welding of jar beam are connected it with bolt 5 with junction plate 2 on being welded on cage guide 1.Be fixedly connected into along the complete dark long cage guide of pit shaft by gusset 3, junction plate 2 and angle steel 5 usefulness bolts 6 and a jar beam by many short cage guides 1, connect with welding manner between short cage guide, the shrinkage joint is not stayed in its joint, so just can make hoisting container do not have along the joint the long cage guide safety at shrinkage joint, fast, reposefully the operation.
