Pressure pipe protective cover is cylindrical, allow pressure pipe be socketed on it is described allow in pressure pipe protective cover, the lower end for allowing pressure pipe is connected with to allowing
Pressure pipe plays the lockset of position-limiting action, and anti-pendant ring is located at below lockset, and the center of anti-pendant ring has one second anchor cable hole, prevents
The one end for falling hook is coupler body, the other end is link, and the edge of anti-pendant ring has the matched through hole of link with anti-fall hook, is prevented
The link of pendant hook is articulated in the through hole of anti-pendant ring, and the coupler body of anti-fall hook is articulated in rock mass, and anchor cable runs through first anchor cable
Hole, allow pressure pipe, lockset, the second anchor cable hole.
Preferably, it is described allow pressure pallet material be metal.
Preferably, described allow the diameter of pressure pipe protective cover to be more than the diameter of the first anchor cable hole.
Preferably, the bottom surface of lockset and the upper surface of anti-pendant ring fit.
Preferably, first anchor cable hole and the second anchor cable hole are circular hole.
Preferably, the tensile strength values of the anchor cable are 1860MPa.
It is described to allow pressure pallet to refer to play the role of to allow the metal plate-like thing of pressure in above technical scheme；The lockset is used
In to allowing pressure pipe to play position-limiting action, the specific can be erosion control lockset or nut or the fixation of position-limiting action are played
The structures such as the pallet of setting.
The present invention provides a kind of cable bolting system with impact resistance, the technical solution is by anchor cable through allowing
Press in pallet, and play the role of allowing the concave part of pressure being provided with through position, meanwhile, in concave part bottom surface, setting allows pressure pipe to protect
Shield and it is built-in wherein allow pressure pipe, allow the bottom of pressure pipe that there is the lockset for playing position-limiting action；Below lockset, the present invention is set
The ring for playing the role of anti-falling protection is put, one end of the ring and anti-fall hook mounts, and the other end of anti-fall hook mounts
On rock mass, so that anchor cable, the undertaking for allowing the components such as pressure pipe, lockset to be subject to anti-pendant ring are protected.The present invention passes through the above
Technological improvement realizes the shock resistance effect of anchor cable in the vertical direction, while has the function of anti-falling protection.
