And pressure-bearing support rods 7 are not required to be arranged on the pressure-bearing sliding sleeves 2 adjacent to the head and the tail of the two energy-absorbing sleeves 4.
The three pressure-bearing support guard plates 10 are buckled together to form a complete cylindrical support cylinder.
The one-time use process of the present invention is described below with reference to the accompanying drawings:
after the drilling construction is finished, according to the diameter of a drilled hole, the distance between the tray 5 and the slide bar stop block 11 is increased by screwing the nut 6, the distance between the pressure-bearing sliding sleeves 2 can be increased by the automatic extension of the pressure-bearing spring 3, and the pressure-bearing support bar 7 is further enabled to deflect towards the pressure-bearing slide bar 1, so that the pressure-bearing support plate 10 approaches towards the pressure-bearing slide bar 1, the radial size of the energy-absorbing shock-proof support device is reduced, and finally the energy-absorbing shock-proof support device can be smoothly inserted into the drilled hole.
After the energy-absorbing shock-absorbing impact-preventing support device is inserted into a drill hole, the nut 6 is reversely screwed to reduce the distance between the tray 5 and the slide bar stop block 11, the compression-resistant spring 3 is compressed by axial pressure, and simultaneously, the distance between the pressure-bearing sliding sleeves 2 is reduced again, so that the pressure-bearing support rod 7 is further deflected towards the inner hole wall of the drill hole, and the pressure-bearing support plate 10 is far away from the pressure-bearing slide bar 1 to increase the radial dimension of the device until the three pressure-bearing support plates 10 are all supported on the inner hole wall of the drill hole in a propping manner, and the installation of the energy-absorbing shock-absorbing impact-preventing support device is finished.
When broken country rock is disturbed and produces the drilling that big displacement deformation arouses and cave in, load capacity is at first used on three pressure-bearing backplate 10, and produce the extrusion force to pressure-bearing backplate 10 in radial direction, make pressure-bearing backplate 10 be close to pressure-bearing slide bar 1, because the distance between tray 5 and the slide bar dog 11 has been fixed, at the in-process that pressure-bearing backplate 10 is close to pressure-bearing slide bar 1, can make pressure-bearing bracing piece 7 further pressure-bearing slide bar 1 deflect, thereby make the interval between pressure-bearing sliding sleeve 2 reduce, and then force compression spring 3 to be compressed, consume impact energy through compression spring 3 tentatively this moment.
If after the compression-resistant spring 3 is compressed to the limit state, the impact energy is not completely consumed, at the moment, the two energy-absorbing sleeves 4 positioned at the head and the tail of the pressure-bearing slide bar 1 are compressed and deformed, so that the impact energy is further consumed by compressing the energy-absorbing sleeves 4, and the effects of preventing the collapse of a drill hole and damping and preventing impact are achieved.
Assuming that the impact energy is not completely offset by the compression energy consumption of the energy-absorbing sleeve 4, the three pressure-bearing supporting plates 10 are finally forced to be completely closed into a complete cylindrical supporting cylinder under the action of the load force, and the cylindrical supporting cylinder can further continuously resist the deformation of the drill hole, so that the purpose of preventing the drill hole from collapsing is finally realized.
The embodiments are not intended to limit the scope of the present invention, and all equivalent implementations or modifications without departing from the scope of the present invention are intended to be included in the scope of the present invention.
