Description

Technical Field

[0001] This utility model relates to the field of drilling rig technology, specifically a multi-joint adjustable drilling rig. Background Technology

[0002] Drilling rigs, as core equipment in geotechnical construction, mining, and geological exploration, are widely used in various drilling operations. Currently, most traditional drilling rigs on the market employ a single-joint drive mechanism for their boom adjustment, using only simple hydraulic cylinders to achieve single-direction boom swing adjustment, resulting in very limited adjustment dimensions. During operation, the boom can typically only perform simple up-and-down pitching movements, making it difficult to simultaneously achieve horizontal turning, multi-position fine-tuning, and other actions, resulting in low overall freedom of movement. When facing complex conditions, such as limited space, multi-directional continuous drilling, or inclined hole drilling, traditional drilling rigs cannot flexibly adjust the spatial position and working angle of the boom and drill bit. Often, the entire rig body needs to be moved for alignment, significantly increasing work procedures, reducing drilling efficiency, and frequently relocating the rig, which can damage the work site and accelerate equipment wear. Furthermore, the single adjustment structure results in poor precision in drill bit angle fine-tuning, making it difficult to meet the requirements of high-precision drilling. The equipment's adaptability to various working conditions is weak, and it is gradually becoming unable to meet the diverse and complex needs of modern drilling operations.

[0003] In view of this, the applicant conducted in-depth research on the above-mentioned issues, which led to this case. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a multi-joint adjustable drilling rig, which can effectively solve the aforementioned technical problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A multi-joint adjustable drilling rig includes a base, a boom, a transition seat, an adjusting seat, a drilling rig base, a first adjusting mechanism, and a second adjusting mechanism. The base includes a side housing with a first rotating shaft rotatably connected to it. The rear end of the boom is hinged to the first rotating shaft. The lower end of the transition seat is hinged to the front end of the boom, and the upper end of the transition seat is hinged to the front end of the adjusting seat. The drilling rig base is connected to the adjusting seat. The first adjusting mechanism includes a first cylinder and a second cylinder. The rear end of the first cylinder is hinged to the first rotating shaft, and the piston rod of the first cylinder is hinged to the lower end of the boom. The side housing has a second rotating shaft rotatably connected to it, and a rotating component is sleeved on the second rotating shaft. The rear end of the second cylinder is hinged to the rotating component. The piston rod of the second cylinder is hinged to the side of the boom. The second adjustment mechanism includes a third cylinder and a fourth cylinder. The rear end of the third cylinder is hinged to the boom, the piston rod of the third cylinder is hinged to the adapter seat, the rear end of the fourth cylinder is hinged to the adjustment seat, and the front end of the fourth cylinder is hinged to the adapter seat. A first mounting seat and a second mounting seat are provided on the first rotating shaft. The rear end of the boom is hinged to the first mounting seat, and the rear end of the first cylinder is hinged to the second mounting seat. A third rotating shaft is provided at the upper end of the adapter seat, and the adjustment seat is hinged to the third rotating shaft. A fifth cylinder is hinged on both sides of the adjustment seat. The front end of the drilling rig base is hinged to the upper end of the adjustment seat, and the piston rod of the fifth cylinder is hinged to the side of the drilling rig base.

[0006] Furthermore, it also includes a support mechanism. The base also includes bottom beams symmetrically arranged at the lower end of the side box. The support mechanism includes a support arm, a sixth cylinder, and a support seat. The side wall of the bottom beam is provided with a third mounting seat. The support arm is hinged to the third mounting seat. The rear end of the sixth cylinder is hinged to the side box. The piston rod of the sixth cylinder is hinged to the rear end of the support arm. The support seat is hinged to the front end of the support arm.

[0007] Furthermore, the lower surface of the support base is provided with several anti-slip toothed strips.

[0008] This utility model provides a multi-joint adjustable drilling rig. It has the following beneficial effects: 1. This utility model adopts a multi-stage hinged joint structure consisting of a boom, adapter seat, and adjustment seat, and is equipped with multiple sets of independent hydraulic cylinders for zoned drive. The first adjustment mechanism can control the boom's vertical pitch and horizontal sway; the second adjustment mechanism can drive the adapter seat and adjustment seat to complete secondary posture adjustments, and in conjunction with the fifth cylinder, it can also independently adjust the angle of the drill base and drill bit. The whole system achieves free adjustment in multiple dimensions, including vertical, horizontal, yaw, and tilt, breaking the limitation of traditional drills that can only swing in one direction, allowing the drill bit to complete angle alignment within a larger space.

[0009] 2. This utility model, relying on its multi-joint, multi-angle adjustment capabilities, allows for hole alignment without frequent movement of the entire drilling rig in complex working conditions such as narrow spaces, obstacles, multi-point drilling, and inclined hole construction. This simplifies the work process, reduces manual labor intensity, effectively shortens alignment time, and significantly improves overall drilling efficiency. Furthermore, each level of hydraulic cylinder independently controls the movement of a single joint, enabling small-amplitude, precise attitude adjustments. Compared to the coarse adjustments of traditional drilling rigs, this results in higher drill bit positioning accuracy, meeting the standards for high-precision drilling operations such as geological exploration and precision pile foundations.

[0010] 3. This utility model is equipped with an independent support mechanism. During operation, the sixth cylinder drives the support arm to lower the support seat to contact the ground. The anti-slip toothed rack at the bottom of the support seat increases the friction with the ground, providing stable support for the entire machine. This effectively counteracts the vibration and reaction force generated during drilling, preventing equipment slippage and tilting. This ensures drilling quality, reduces impact wear on the machine body and hinged parts, and extends the service life of the equipment. Attached Figure Description
