[0059] A vehicle-mounted chassis assembly 1, a hydraulic oil tank 2 is installed on the left side of the surface of the vehicle-mounted chassis assembly 1, a mining computer 3 is installed on the top of the hydraulic oil tank 2, a main operating table 4 is installed on the surface of the vehicle-mounted chassis assembly 1 and located on one side of the hydraulic oil tank 2, and an electric control box 5 is installed on the top of the main operating table 4;

[0060] A hydraulic pump station 6, which is installed on the surface of the vehicle chassis assembly 1 and is located on one side of the main operating table 4;

[0061] A clamp assembly 9, wherein the clamp assembly 9 is arranged on one side of the bottom of the vehicle-mounted chassis assembly 1, a shackle assembly 10 is installed at the bottom of the vehicle-mounted chassis assembly 1 and at one side of the clamp assembly 9, a power head displacement measuring part 13 and a feeding mechanism 14 are respectively installed at the center position inside the vehicle-mounted chassis assembly 1, a power head assembly 15 is installed inside the vehicle-mounted chassis assembly 1 and at one end of the power head displacement measuring part 13, and an automatic upper rod assembly 16 is arranged on one side of the bottom of the vehicle-mounted chassis assembly 1.

[0062] The vehicle chassis assembly 1 includes a frame weld 11 , ends of which are respectively mounted with an anchor cylinder assembly 7 and a double anchor cylinder assembly 8 , and a surface of the frame weld 11 is provided with a plurality of guide rods 12 .

[0063] The hydraulic oil tank 2 includes an oil tank body 21, and a first oil tank cover plate 22 and a second oil tank cover plate 26 are respectively installed on the surface of the oil tank body 21. A liquid level and liquid temperature gauge 23 is arranged on one side of the surface of the oil tank body 21. A return oil filter 24 and an air filter 25 are respectively installed on both sides of the top of the oil tank body 21. An oil suction pipe assembly 27 is installed at the bottom of one side of the oil tank body 21.

[0064] The main operating table 4 includes an operating frame 41 , a plurality of pressure gauges 42 are disposed on the surface of the operating frame 41 , and a seven-way multi-valve 43 and an oil block assembly 44 are disposed inside the operating frame 41 .

[0065] The hydraulic pump station 6 includes an electric motor 61 , one end of which is fixedly connected to a main pump 63 via a coupling 62 , and one end of the main pump 63 is connected to an auxiliary pump 64 .

[0066] The clamp assembly 9 includes a front clamp base 91, a front clamp steel cylinder assembly 92 is installed on the surface of the front clamp base 91, a front clamp movable plug 93 is arranged on the front clamp steel cylinder assembly 92, a stabilizer 96 is arranged on the surface of the front clamp base 91 and on one side of the front clamp steel cylinder assembly 92, and a cava seat 94 and a cava 95 are respectively arranged on the surface of the stabilizer 96.

[0067] The function of the vehicle chassis assembly 1 is to install the motor components, power head and fuel tank of the drilling vehicle. It can reach a free walking speed of 20m / min and a climbing ability of ±20°. The function of the adjusting cylinder is to adjust the inclination angle of the drilling rig.

[0068] The hydraulic oil tank 2 converts the electric energy of the motor into hydraulic energy (pressure oil) during the operation of the drilling rig, and plays a storage role.

[0069] The mining computer 3 summarizes and displays various data of the drilling rig. When the drilling rig is working, the working status of the drilling rig can be grasped in real time, which can assist in better controlling the drilling rig.

[0070] The main operating console 4 is the switch assembly of various source components on the drilling rig to control the opening and closing of each cylinder. It plays an auxiliary role on the fully automatic drilling rig and can temporarily replace the remote control to control the operation of the drilling rig when the remote control fails.

[0071] Please refer to Figure 8 and Fig.10 It is known that the hydraulic pump station 6 is the power source of the drilling rig, which converts electrical energy into hydraulic energy. The motor drives the oil pump to rotate through the coupling. The oil pump draws oil from the oil tank and outputs pressurized oil. The high-pressure oil output by the main pump supplies the power head to rotate and feeds the oil cylinder to advance and retreat quickly; the high-pressure oil output by the auxiliary pump supplies the chuck, clamp and brake to open and close, and normally propels the oil cylinder forward and backward, and supports the oil cylinder, etc.

[0072] The anchor cylinder assembly 7 and the double anchor cylinder assembly 8 are installed on the chassis assembly 1. The anchor cylinders are located at the four corners of the vehicle body. The vehicle body is stable, convenient and reliable after supporting, and has strong adaptability. Two of the anchor cylinders are provided with anchors, and the anchoring force can reach 250kN.

[0073] The structure and working principle of the clamp assembly 9 are similar to those of the breaker. After the high-pressure oil enters the clamp cylinder, it pushes the clamp piston to move axially. The slip installed on the inner inclined surface of the clamp piston applies radial pressure to the axially limited slip through the axial displacement of the piston, thereby realizing the clamping function. The front clamp is installed at the front end of the frame. Its function is to disassemble and assemble the drill pipe and prevent the drill pipe from slipping out of the borehole. It cooperates with the drill pipe connecting shaft to tighten or loosen the connecting threads between the drill pipes. The auxiliary pump provides high-pressure oil to the front clamp to provide a power source for clamping and loosening the front clamp.

[0074] The power head assembly 15 includes two hydraulic motors 152, one end of the two hydraulic motors 152 is provided with a reduction box 153, one side of the reduction box 153 is connected to a water jacket 151, one side of the reduction box 153 is connected to a main shaft 154, and one side of the main shaft 154 is connected to a drill pipe connecting shaft 155.

[0075] Please refer to Fig.11 and Fig.12It is known that the power head assembly 15 is a mechanism that converts hydraulic energy into mechanical energy. The high-pressure oil drives the hydraulic motor to rotate, and is transmitted to the reduction box through the brake and planetary reduction. After deceleration, it drives the main shaft and drill bit to rotate, and outputs speed and torque. The reduction box is a two-stage gear reduction. By adjusting the "rotation motor torque" knob on the main operating console, the displacement of the hydraulic motor can be changed to achieve stepless speed regulation. The auxiliary pump enters the oil distribution sleeve through high-pressure oil, and drives the drill pipe connecting shaft to rotate through the main shaft to achieve connection and removal of the drill pipe. When entering the rotary condition, the oil pressure is large and the temperature rises rapidly. At this time, the flushing and cooling function is automatically turned on.

[0076] The automatic rod-lifting assembly 16 includes a large arm 167, one end of which is respectively connected to a slewing base 161 and a lifting cylinder 162, the other end of the large arm 167 is connected to a swing cylinder seat 163, one end of the swing cylinder seat 163 is connected to a grabbing assembly 164, one side of the grabbing assembly 164 is connected to a guide bracket 165, and one side of the guide bracket 165 is installed with a swing cylinder 166.

[0077] Please refer to Fig.13 It is known that the automatic rod-lifting mechanism is mainly composed of a rotating base 161, a large arm 167, a swing cylinder seat 163 and a grabbing assembly 164 (including a manipulator grabbing device and a lifting device). The large arm 167 is controlled to swing up and down by the lifting cylinder 162 to adjust the vertical angle. The position of the grabbing assembly 164 is controlled by rotating the swing cylinder seat 163 to facilitate grabbing the drill rod from the drill rod bin and installing it on the drilling rig; or the drill rod is removed from the drilling rig and placed in the drill rod bin. The grabbing assembly 164 grabs the drill rod through the clamping cylinder, and adjusts the height of the drill rod through the lifting device to facilitate the loading and unloading of the drill rod.
