Description
Technical field
The utility model 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 collapses
Disconnected 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 utility model 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 utility model breaks, it includes: Protective nut, steel wire
Rope and steel wire rope clamp, the safety device which breaks are mounted on the upper clip and U for clamping U-shaped canopy card cable
On the bolt of the lower clamping piece of type canopy card cable, the lower clamping piece of the upper clip of U-shaped canopy card cable and U-shaped canopy card cable is logical in UXing Peng lap-joint
Cross two bolt fastenings together, in which: Protective nut includes: upper cap nut and lower nut, and upper cap nut is weldingly fixed on lower nut,
The center line of upper cap nut is perpendiculared to one another with the center line of lower nut, and lower nut is tightened on each bolt, and steel wire penetrating is each
Hole among upper cap nut, 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 utility model breaks, in which: the wirerope clip pack
Include: U-bolt, snap-gauge and nut, snap-gauge upper end pass through the both ends of U-bolt, and it is U-shaped that two nuts are tightened in snap-gauge upper end respectively
On the screw thread of bolt, 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 utility model breaks, in which: the upper cap nut and lower spiral shell
The size of cap 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.

Specific embodiment
As shown in Figure 1 to Figure 3, the safety device that the U-shaped canopy card cable bolt of the utility model breaks includes: protection spiral shell
Cap 1, wirerope 2 and steel wire rope clamp 3, the safety device which breaks, which is mounted on, clamps U-shaped canopy card cable
On the bolt 4 of the lower clamping piece 12 of upper clip 5 and U-shaped canopy card cable, the lower clamping piece 12 of the upper clip 5 of U-shaped canopy card cable and U-shaped canopy card cable
It is tightened together in 6 lap-joint of UXing Peng by two bolts 4, Protective nut 1 includes: upper cap nut 8 and lower nut 7, upper cap nut 8
It is weldingly fixed on lower nut 7, the center line of upper cap nut 8 is perpendiculared to one another with the center line of lower nut 7, upper cap nut 8 and lower nut 7
