Before operation, the jacking oil cylinder and the drilling oil cylinder are connected with a hydraulic system on a truck crane through high-pressure oil pipes, a constructor can enter two constructors in the hanging basket body, after the truck crane lifts the hanging basket body and the drilling oil cylinder to a construction site, the constructor works in the hanging basket body, after a drilling point is marked, the jacking oil cylinder is started to enable the guide rail to rotate by taking the upper end of the support as a fulcrum, when the drill bit is vertical to the rock wall, the drilling oil cylinder and the impact-resistant motor are started, a piston rod of the drilling oil cylinder extends to drive the impact-resistant motor to move forwards along the guide rail, and the drill bit rotates at a high speed to drill the rock wall. After drilling, the hanging basket body is moved by controlling the truck crane to drill the next rock wall.
As the drill bit drills hard rock walls, a main shaft of the anti-impact motor can be subjected to strong impact force. The left end of a main shaft of the anti-impact motor is a power output end, when the left end of the main shaft is impacted axially, the main shaft can suddenly move rightwards, a guide groove in the main shaft moves rightwards along a guide block fixedly arranged on an inner ring of a bearing, the right end of the main shaft can drive a guide pillar, the guide pillar drives a compression spring to jack a blocking plate rightwards, meanwhile, the guide pillar generates thrust to hydraulic oil, the hydraulic oil in an inner cylinder body is squeezed into an annular cavity through an oil hole, as the guide pillar moves leftwards and rightwards, a sealing ring on the guide pillar can block the oil hole in the inner cylinder body, an oil hole channel between the inner cylinder body and the annular cavity is reduced, the pressure of the hydraulic oil in the inner cylinder body is increased, the hydraulic oil can perform good buffering and pressure reduction, the compression spring also performs good buffering effect, so that the bearing is prevented from receiving impact force, and the bearing is effectively protected.

The clamp spring is used for positioning the axial position of the right bearing.
When the compression spring is in a fully extended state, the right end part of the compression spring is contacted with the right end cover, and meanwhile, the right end part of the guide block is contacted with the right end part of the guide groove; this positions the spindle in the axial direction when the spindle is not subjected to an axial impact force.
The volume of the annular cavity is smaller than that of the inner cylinder, and the volume of the hydraulic oil is equal to that of the inner cylinder, so that after the annular cavity is filled with the hydraulic oil, a part of hydraulic oil is still in the inner cylinder, and the phenomenon that the guide pillar firmly touches the hard stress when the compression spring is pressed to the shortest limit is avoided.
In addition, the anti-impact motor is frequently damaged when the hanging basket body is in the field for a long time, so that the upper half shell needs to be disassembled, and the connecting nut and the connecting bolt between the upper half shell and the lower half shell need to be ensured to have good thread matching performance, so that the anti-corrosion bolt connecting assembly is arranged between the upper half shell and the lower half shell. The concrete installation process and the rust-corrosion prevention principle of the rust-corrosion-prevention bolt connecting assembly are as follows: in the draw-in groove and the constant head tank of installing four spacing to four U type spring correspondences earlier, place the second ring inslot to a spacing again, use a set screw to fix this spacing, use set screw and fix the second ring inslot to another three spacing in proper order after that, four set screws are countersunk head structure, because U type spring's effect, the equal protrusion of expansion end of four spacing goes up holding ring inner wall and holding ring inner wall down. After the connecting nut at the upper end of the connecting bolt is screwed down, an operator holds the protective cap by hands, the protective cap is sleeved on the connecting nut and the connecting bolt and is pressed downwards, the part of the outer circumference of the gasket above the first circular groove is in a cone-shaped structure with a thin upper part and a thick lower part, and the thickness of each limiting strip along the radial direction is in a structure with a thick upper part and a thin lower part, namely the cone-shaped matching structures between the inner walls of the four limiting strips and the outer wall of the upper part of the gasket easily press the four limiting strips into the first circular groove on the outer circumference of the gasket, the inner walls of the four limiting strips tightly press the circumferential wall of the first circular groove under the action of the U-shaped spring, and the protective cap is firmly fixed with the connecting bolt integrally, so that a good rain-proof effect is achieved, and threaded connection between the connecting nut and the connecting bolt is effectively protected from being rusted. When the connecting bolt needs to be disassembled, the protective cap needs to be cut off firstly. The cooperation of the upper positioning ring, the lower positioning ring and the gasket on the inner wall of the protective cap not only has a positioning function, but also has the functions of sealing and preventing rainwater from invading the joint of the connecting bolt and the connecting nut.
