Description
Technical field
The present invention relates to the U-shaped canopy supporting of underground coal mine attach device more particularly to a kind of U-shaped canopy card cable bolt breaks
Safety device, once solving, Tunnel Pressure is big, and generation card cable bolt breaks projects casualty accident.
Background technique
Coal mine is pressed to mine and is incrementally increased as mining work activities are gradually to deep deepening, and conventional anchor net support pattern is not
Roadway support needs are able to satisfy, new pick tunnel and broken reparation tunnel are more and more using U-shaped canopy support pattern.With mining depth
Increase, high stress and soft rock mine roadway generally occurs, and Tunnel Pressure increases, and tunnel unstable phenomenon also occurs in U-shaped canopy supported laneway.It is U-shaped
When canopy supported laneway pressure increases, often there is the card cable fastening bolt in U-shaped canopy supporting construction and break injection.Such case
Under, when thering is pedestrian to pass through, seriously threaten the life security of worker.
Summary of the invention
The purpose of present invention is the injection that breaks for the card cable fastening bolt solved in U-shaped canopy supporting construction, is threatened
The life security of worker, the present invention provide a kind of U-shaped canopy card cable bolt and break safety device.
In order to complete present invention purpose, the application uses following technical scheme:
The safety device that a kind of U-shaped canopy card cable bolt of the invention breaks, it include: Protective nut, wirerope and
Steel wire rope clamp, the safety device which breaks are mounted on the upper clip and U-shaped canopy for clamping U-shaped canopy card cable
On the bolt of the lower clamping piece of card cable, the lower clamping piece of the upper clip of U-shaped canopy card cable and U-shaped canopy card cable passes through two in UXing Peng lap-joint
A bolt fastening is together, in which: Protective nut includes: upper cap nut and lower nut, and upper cap nut is weldingly fixed on lower nut, upper spiral shell
The center line of cap is perpendiculared to one another with the center line of lower nut, and lower nut is tightened on each bolt, and steel wire penetrating each goes up spiral shell
Hole among cap, it is clamping fixed that the both ends of wirerope pass through wirerope respectively；
The safety device that a kind of U-shaped canopy card cable bolt of the invention breaks, in which: the wirerope folder includes: U-shaped
Bolt, snap-gauge and nut, snap-gauge upper end pass through the both ends of U-bolt, and two nuts are tightened in snap-gauge upper end U-bolt respectively
On screw thread, snap-gauge lower end is in W type, and snap-gauge lower end is pressed in from the wirerope passed through in U-bolt；
The safety device that a kind of U-shaped canopy card cable bolt of the invention breaks, in which: the top nut and lower nut
Size is identical.
The application is to twist the Protective nut processed admittedly in the card cable fastening bolt in conventional u-shaped canopy supporting construction, be used in combination
Wirerope by it is all twist solid Protective nut and wear be connected into an entirety.When certain root card cable fastening bolt is disconnected in U-shaped canopy supporting construction
When splitting, break bolt is fully twisted solid on the Protective nut for passing through wirerope, is caught hold of fracture and is flown out bolt, prevents break bolt
It flies out and hurts sb.'s feelings.
