Description

Technical Field

[0001] The invention relates to the technical field of drilling, and in particular to a reinforcing fixing device for a drilling machine. Background Art

[0002] As a key equipment in the fields of mineral resource exploration, geological survey, construction engineering, etc., the operating stability of drilling rigs directly determines the drilling accuracy, construction efficiency and equipment service life. In complex geological environments or high-load operating conditions, drilling rigs often have the risk of displacement or overturning due to vibration, impact force and formation reaction force, especially in soft, inclined or broken formations, where the performance shortcomings of traditional fixing devices are more significant.

[0003] In the prior art, the main methods of fixing drilling rigs include anchor bolts, counterweights, and hydraulic supports. Although the counterweights can suppress vibration displacement by increasing the deadweight, it greatly increases the cost of equipment transportation and deployment, and is difficult to adapt to undulating terrain or narrow working spaces. The hydraulic support device adjusts the horizontality of the drilling rig through a multi-leg structure, but its rigid support mode exerts too high local pressure on the ground, which can easily cause ground collapse, and lacks an effective energy dissipation mechanism under dynamic impact, causing vibration energy to be transmitted back to the main body of the drilling rig, accelerating component fatigue. Summary of the invention

When the drilling machine is working, the drilling mechanism is completely connected and supported by the big arm on the vehicle body.

[0034] Working principle: When the present invention is in use, when the drilling equipment is working, the boom 1 will be lifted to align the drill bit with the target position. Before drilling, the fixing device needs to be deployed. First, due to the change in the lifting angle of the boom 1, the stepper motor II8 is started to drive the worm I7 to rotate, thereby driving the rotating frame 9 to rotate, so that the rotating frame 9 rotates a certain angle, so that the support rod 18 is adjusted to a vertical angle, and then the stepper motor I5 is started to drive the screw rod 4 to rotate, thereby driving the slider 6 to slide on the slide rail 3, so that the position of the support point of the support rod 18 is moved, so as to select the best support position. Then the stepper motor III 13 is started, driving the worm II 12 to rotate, thereby driving the worm wheel II 11 to rotate, thereby driving the fine-tuning frame 10 to rotate, and then driving the support rod 18 to rotate, so that the lower end of the support rod 18 moves outward to form an outward eight support trend, and finally the stepper motor IV 14 is started, driving the worm III 15 to rotate, thereby driving the gear 17 to rotate, and the gear 17 drives the support rod 18 to slide downward, so that the support leg 21 contacts the ground, and the compression spring 19 can play a buffering role on the bottom frame 20, and the spring rod 22 also plays a buffering role on the support leg 21, thereby protecting the support device; Since the support rods 18 are tilted to the outside at a certain angle on both sides, the telescopic rod 24 is extended and retracted in the telescopic rod sleeve 26. After the adjustment, the activity of the telescopic rod 24 needs to be locked, and the hydraulic cylinder 27 is started to drive the piston rod to slide, thereby squeezing the friction block 29 to slide downward. The bottom of the friction block 29 contacts the telescopic rod 24, so that the telescopic rod 24 is locked by friction, ensuring the stability between the two support rods 18. In this way, an overall support system is formed, which makes the drilling more stable and not easy to shake.
