Description

But rail guide compression apparatus

Technical field

But the utility model relates to a kind of pitshaft rail guide, buntons of making and adapts to the compression apparatus that shaft lining breakage sinks dynamically freely, but especially at basement rock and the silting deposit interface position of borehole wall stress concentration with the rail guide compression apparatus of the position setting of shaft lining breakage sinking has taken place.

Background technology

Be the resource that develops a mine, need the face of land be communicated with underground by shaft of vertical well; For the down-hole resource is carried to the face of land, lifting container need come and go lifting along pit guide.With the coal mine shaft lining pit shaft is example, for the auxiliary shaft of services such as lifting personnel, facility, material, equipment, spoil, is lifting container with the cage, under the traction of ground lifting winch, and the reciprocal lifting of stationarity cage guide fixing along rising, directional tagging; For the main main shaft that promotes the coal service, be lifting container with the skip bucket, under the traction of ground winch, along the reciprocal lifting of pit guide.But owing to many vertical freezing shaft walls and drilling shaft lining generation break accident are arranged today from crossing to go to, and bring corresponding destruction to shaft equipment, bring certain difficulty and danger also for normal lifting work.Entangle its shaft wall fracture major cause: the one, show native water stratum and produce consolidation settlement because of hydrophobic; The 2nd, soil body constraint borehole wall rising-heat contracting-cold; The 3rd, freezing shaft wall is at the back thaw collapse that thaws; The 4th, surface water is to underground infiltration.Above a variety of causes all produces to some extent and covers soil body sinking, the soil body is in the sinking process, borehole wall appearance is produced downward application force---vertical additional force, when this power arrives certain value, cause the borehole wall at basement rock and silting deposit interface position or other position break, sink.According to the pertinent data analysis, this vertical additional force is subjected to objective factor restriction unavoidable, different and shaft wall structure design and construction method, construction quality of geology, Di Kuang, landforms and amblent air temperature different separately just, and the subsidiary load size is also different.

Because the destruction of the borehole wall is sunk, the buntons that drive is taken root on the borehole wall together sinks, buntons is oppressed cage guide again, making it to be in cage guide, buntons and the buntons at positions such as basement rock and silting deposit hand-deliver interface and the borehole wall takes root and a little at first is affected, and then progressively two-way up and down influence, the destruction situations such as a dial-out of twisting, be out of shape, take root until obvious appearance can't normally be carried out lifting work.At this moment; people write an article on the borehole wall often; next is to take passive repairing and " trimming the feet to fit the shoes " on shaft equipment---progressively cuts short cage guide or changes ways such as cage guide and buntons and adapt to shaft lining breakage and sinking; and ignored the variation that how to make cage guide, buntons etc. adapt to the borehole wall dynamically freely, thereby the problem of protection security improvement.

Summary of the invention

The purpose of this utility model just provides a kind of concentrating in shaft lining stress and has produced and easily to have produced the special device that destroys, adopts the assurance security improvement operation that moves freely with the borehole wall of being convenient to measure observation on the cage guide at sinking position.

Be achieved in that order of the present utility model

This device is made up of the special rail guide in top, the special rail guide in bottom, special railways splint and tie bolt respectively.But the rail guide compression apparatus is to be pegged graft with bottom special rail guide female end head by the top special rail guide male end head that intensity is equal to or is higher than former cage guide to cooperate, and formation criss-cross connecting joint can move freely in vertical direction.Criss-cross connecting joint four sides vertically form continuous cross-section, do not have elongated transversal surface seam.This device is formed the one combined action with original buntons, original rail guide clamp.But the rail guide compression apparatus can be located at pit shaft basement rock and silting deposit interface position section, and the borehole wall position section that can contract also can be located at the borehole wall simultaneously sedimentation compressive deformation position or other position that needs have taken place maybe may take place.A position section two groups or many groups can be set continuously as required.

Distinguishing feature of the present utility model is:

1. criss-cross connecting joint intensity height, good stability.

2. each free-running fit of joint is meticulous, and horizontal offset is little, and except that vertical direction can move freely, horizontal all directions can not be rocked.

3. the cage guide stroke can be determined according to the mine situation, and is adjustable before the fabrication and installation.

4. need other processing and fabricating except that the special rail guide in top, the special rail guide in bottom, special railways splint, other all adopts existing facility as cage guide, buntons, rail guide clamp etc., and the dismounting amount is little, and on-site installation is easy.

5. peg graft and cooperate the back to form the criss-cross connecting joint in rail guide male and female termination, and all side surfaces of joint can be continuous, do not have elongated transversal surface seam, is beneficial to the fixedly cage shoe operation of lifting container.

6. can intuitively measure inspection by criss-cross connecting joint position.By the variation of this position stroke, get final product the variation that dynamic reflection goes out the borehole wall, help the borehole wall is in time taked Corresponding Countermeasures.
