Technical field
The utility model relates to the shaft of vertical well equipment in a kind of Mineral Engineering, relates in particular to a kind of guiding cage guide of mine vertical shaft pit shaft lifting container.
Background technology
In recent years, many places shaft of vertical well shaft wall fracture phenomenon appears in east China and mining area, middle part, and the pit shaft shaft wall fracture has caused very big influence to the ordinary production of mine.By studies show that of domestic scientific research institution, the major cause of shaft wall fracture is owing to shaft of vertical well has born the vertical subsidiary load effect that the soil body sinks to producing.In order to prevent shaft wall fracture and distortion, must improve shaft wall structure, make the vertical borehole wall have the characteristic of " resisting ", " allowing " or " anti-allow in conjunction with ", currently used compressible shaft wall structure has the characteristic of " anti-allow in conjunction with ", the destruction that can prevent the borehole wall effectively.But, because all being furnished with the guiding facility of lifting container in the shaft of vertical well usually is shaft equipment, the borehole wall deforms and certainly will cause the shaft equipment structure to produce distortion or displacement, normal operation to lifting container is very unfavorable, and therefore the contracted shaft equipment new construction of exploitation adaptation borehole wall distortion just becomes a kind of necessity.
The mine vertical shaft shaft equipment mainly comprises the cage guide that is used for the lifting container guiding and supports jar beam (or carriage) composition of cage guide, because cage guide is installed on the borehole wall, can be out of shape along with the compressive deformation of the borehole wall, when compressive deformation takes place in the vertical borehole wall under vertical subsidiary load effect, the parallelism of cage guide and squareness all can't be guaranteed, produce serious swing and card jar accident in the time of can making the lifting container operation, the safety that is threatening mine hoisting work.
Summary of the invention
To be solved in the utility model is that shaft of vertical well produces vertically distortion owing to a variety of causes causes the borehole wall in the prior art, and the cage guide of lifting container operation can not be out of shape thereupon in the pit shaft, lifting work is produced the technical matters of potential safety hazard, a kind of vertical cage guide that can contract is provided, can guarantee that lifting container normally moves along cage guide, help the security improvement and the high and stable yields of mine.
In order to solve the problems of the technologies described above, the utility model is achieved by following technical scheme:
A kind of vertical cage guide that can contract, comprise rectangular steel tube, described rectangular steel tube one side is connected with the connecting panel that is used for fixing on the jar beam, described rectangular steel tube bottom is welded with the cage guide gear shaping, described cage guide gear shaping is plugged with it and is cross-linked the cage guide socket that cooperates, and described cage guide socket is fixed by a connecting panel and a jar beam.
Described cage guide gear shaping and described cage guide socket constitute by a plurality of grafting bars.
The grafting sliver transvers section of described cage guide gear shaping and described cage guide socket is a dove-tail.
Described rectangular steel tube, described connecting panel, described cage guide gear shaping and described cage guide receptacle face are provided with preservative coat.
The beneficial effects of the utility model are:
(1) the utility model is designed according to the characteristics as a result of cage guide, can neither change the layout of shaft equipment, also need not adjust the anchor fitting of cage guide, vertical can contract cage guide in adjacent two bound layer spacings that it is installed, when the vertical borehole wall produces distortion under vertical subsidiary load effect, this vertical cage guide deform in same pace thereupon that can contract has kept due squareness of cage guide and parallelism, and the safety of lifting container operation is protected.
(2) the utility model utilizes the transition method that cage guide gear shaping and cage guide socket are cross-linked, and guarantees the continuity of cage guide guide track.
(3) the grafting sliver transvers section of cage guide gear shaping of the present utility model and cage guide socket is designed to be dove-tail, utilize the coupling of dovetail furrow to control the displacement of cage guide on the cross section, keep the squareness of cage guide, guarantee the normal operation of lifting container along cage guide thereby reach.
(4) compress variation of the present utility model can design according to the actual requirement of borehole wall distortion, uses flexibly.
(5) cage guide of the present utility model can guarantee to have higher strength and stiffness.
(6) the same specification of the common cage guide of cage guide of the present utility model, the convenient installation both can be used for the installation of New Built Mine shaft equipment, also can be used for the transformation of existing pitshaft equipment, and easy construction is simple, and maintenance is few, and social benefit is good, is easy to promote the use of.
Description of drawings

Fig. 2 is the A-A section drawing of Fig. 1;
Fig. 3 is the B-B section drawing of Fig. 1;
Among the figure: 1: rectangular steel tube; 2: connecting panel; 3: the cage guide socket; 4: the cage guide gear shaping.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail:
As shown in Figure 1, present embodiment has disclosed a kind of vertical cage guide that can contract, and is made of rectangular steel tube 1, connecting panel 2, cage guide socket 3 and cage guide gear shaping 4.
In conjunction with shown in Figure 2, the top of rectangular steel tube 1 and middle part are connected with connecting panel 2 respectively, and described connecting panel 2 is welded in rectangular steel tube 1 one sides, be used for be fixed on the borehole wall on the jar beam (or carriage) be connected.
Cage guide gear shaping 4 belows are provided with the cage guide socket 3 with its coupling, and cage guide socket 3 outsides are surrounded by the four sides, and each face is arranged at intervals with three grafting bars, the grafting bar of the corner formula that can be welded as a whole, and the centre is provided with and the corresponding cylindrical shell of above-mentioned cylinder.Cage guide gear shaping 4 bottoms one face down bonding is connected to connecting panel 2, connecting panel 2 be used for be fixed on the borehole wall on the jar beam (or carriage) be connected.
