It is many that the modes such as gib are tunneled using forestope gib, machine-carried type gib, automatic moving type.
Although having taken certain safety measure for the gib of coal mine underground tunneling roadway, and achieve certain
Effect, but by the yoke of the uncertain factor such as underworkings geological conditions is changeable, still suffer from certain potential safety hazard.Forestope
(utilizing π types beam or steel pipe, plank etc.) needs many people to coordinate, laying twists jack rafter plate and carries on the back tight back of the body jail, and it is laborious that this is time consuming；Its
It is secondary to belong to passive protecting, there is no setting load, support capacity is had a greatly reduced quality；Furthermore, it is inevitable in empty top zone domain during manual work
Operation, there is certain danger.And Onboard temporary supporting device and automatic moving type temporary support device for drivage, although mitigate workman's work
Intensity, shortens the gib time, and safety coefficient is increased substantially, but meets lane space not enough, is limited to scrap build, with
And the problems such as equipment investment, in coal（Rock）Using less in the driving in lane.Therefore, a kind of simple reliable gib dress is designed
Put imperative.
The content of the invention
For above-mentioned situation, for the purpose for overcoming the defect of prior art, the utility model is just to provide one kind for coal
The umbrella shape point pillar gib in ore deposit tunnel, can effectively solve to improve the intensity of laneway temporary support, mitigate underground labour's work
Operation intensity, realizes the safe, reliable, efficient problem of tunnelling gib.
The utility model solve technical scheme be, a kind of umbrella shape point pillar gib for coal mine roadway, including
Umbrella shape backplate and strong point post, umbrella shape backplate include main frame, and main frame is the 2 cross-brace peace set by parallel spaced-apart
The plane frame structure that multiple longitudinal bracings that row is arranged between 2 cross-braces are constituted, is provided with convex on main frame
The curved support frame corresponding with coal mine roadway vault radian for rising, equipped with support tie-beam, strong point post on curved support frame
Including base, height adjustable column and cylinder, the upper end of cylinder is connected with support tie-beam, and the lower end of cylinder is provided with screw thread
Set, the upper end of base is provided with lower thread bush, is respectively arranged with the outer wall at height adjustable column two ends and lower thread bush, upper screw thread
The corresponding external screw thread of set, the top of height adjustable column is rotated in upper thread bush through the external screw thread of upper end, and bottom is through lower end
External thread rotary constitutes adjustable for height attachment structure in lower thread bush.
The utility model structure novel and unique, advantages of simple is easily assembled, the activity duration is short, high working efficiency, supporting effect
It is good, the intensity of laneway temporary support is effectively improved, mitigate underground labour's labor operation intensity, realize tunnelling gib
Safe, reliable, efficient, easy to use, effect is good, is the innovation in tunnel gib.
