[0002] In horizontal directional drilling rigs, the angle adjustment mechanism of the main beam is an important mechanical device. It is used to adjust the angle of the drilling rig main beam to adapt to different drilling angles and path requirements. By adjusting the angle of the main beam, the drilling rig can drill from the surface into the ground and change the drilling direction as needed. This is crucial for avoiding underground obstacles or meeting specific engineering requirements. For example, the patent with announcement number CN222668112U (a variable angle adjustment mechanism for the main beam of a horizontal directional drilling rig): includes a main boom, an inner rotating barrel is movably connected inside the main boom, a drill bit is threaded to the bottom end of the inner rotating barrel, a circular groove is opened inside the drill bit, and several sets of racks are fixedly connected to the inner wall of the circular groove, one side of a gear is engaged with the inner wall of the rack, a gear two is engaged with the other side of the gear one, and the output end of a motor is fixedly connected inside the gear two; Although the aforementioned existing technology starts the motor and adjusts the angle of the drill bit at the drill bit, causing the drill bit angle to shift, it lacks an angle monitoring structure. Consequently, when adjusting the angle of the horizontal directional drilling rig beam, it is not easy to accurately know the angle data, affecting the accuracy of the beam angle adjustment. Therefore, the market urgently needs to develop a variable angle adjustment mechanism for the horizontal directional drilling rig beam to help people solve the existing problems.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Please see Figure 1-4An embodiment of this utility model provides an angle adjustment mechanism for the main beam of a horizontal directional drilling rig, comprising a platform 3, a drilling rig beam arm 2 fixedly installed on the top of the platform 3, support side plates 4 symmetrically arranged on one side of the front and rear ends of the platform 3, and rotating shafts 15 symmetrically fixedly installed on the front and rear ends of the platform 3, the rotating shafts 15 being located between the platform 3 and the support side plates 4, one end of the rotating shafts 15 penetrating through the support side plates 4 and rotatably connected to the support side plates 4, a gear 16 fixedly installed on the outer side of the rotating shafts 15, a gear 2 17 meshing below the gear 16, both gear 16 and gear 2 17 being helical gears, a convex plate 18 arranged below the gear 2 17, the convex plate 18 being fixedly connected to the support side plates 4, an encoder 19 fixedly installed below the convex plate 18, the measuring end of the encoder 19 being fixedly connected to the gear 2 17 via a shaft.

[0018] The encoder 19 is used to detect the gear rotation angle in real time, and the actual tilt angle of the beam is fed back through the gear meshing relationship. This allows the operator to intuitively grasp the adjustment data, improve the accuracy of angle adjustment, and the symmetrically arranged support side plate 4 and rotating shaft 15 structure ensures stable and reliable angle measurement, increasing practicality.

[0019] Furthermore, a mounting base plate 1 is fixedly installed below the supporting side plate 4, and an upper mounting seat 5 is fixedly installed in the middle of one side below the platform 3. A hydraulic cylinder 6 is provided below the upper mounting seat 5. The upper mounting seat 5 is rotatably connected to the piston rod end of the hydraulic cylinder 6. A lower mounting seat 7 is rotatably installed below the hydraulic cylinder 6. The lower mounting seat 7 is fixedly connected to the mounting base plate 1. Both the upper mounting seat 5 and the lower mounting seat 7 are U-shaped plates.

[0020] The hydraulic cylinder 6 can effectively drive the platform 3 to rotate and adjust the angle, increasing its practicality.

[0021] Furthermore, a support mechanism 8 is provided above the mounting base plate 1. The support mechanism 8 includes a mounting frame 801, an electric cylinder 802, a top plate 803, and a second top plate 804. The mounting frame 801 is fixedly connected to the mounting base plate 1. The electric cylinder 802 is fixedly installed inside the mounting frame 801. The top plate 803 is located above the mounting frame 801. The push rod end of the electric cylinder 802 slides to the top of the mounting frame 801 and is fixedly connected to the top plate 803. The second top plate 804 is fixedly installed above the top plate 803.

[0022] The support mechanism 8 provides additional support. The height of the top plate 803 can be controlled by the telescopic movement of the electric cylinder 802. This design allows the horizontal directional drilling rig to adjust the support height according to actual needs during operation, thereby supporting the platform 3 and improving the safety and reliability of the equipment.

[0023] Furthermore, guide posts 11 are symmetrically arranged at the front and rear ends of the electric cylinder 802, and the upper end of the guide post 11 slides to the top of the mounting plate 801 and is fixedly connected to the top plate 803.

[0024] The guide column 11 can guide the lifting and moving of the top plate 803, increasing the linear stability of the lifting and moving of the top plate 803.

[0025] Furthermore, stabilizing side plates 9 are symmetrically arranged at the front and rear ends of the platform 3. The lower end of the stabilizing side plate 9 is fixedly connected to the mounting base plate 1. An arc-shaped hole 901 is provided inside the stabilizing side plate 9. An electric cylinder 12 is fixedly installed below the platform 3. A transmission column 13 is installed on one side of the electric cylinder 12. The push rod end of the electric cylinder 12 is fixedly connected to the transmission column 13. One end of the transmission column 13 passes through the arc-shaped hole 901 through the stabilizing side plate 9 and a circular plate 10 is fixedly installed thereon.

[0026] After the platform 3 is angled, the push rod end of the drive electric cylinder 12 retracts and is driven by the transmission column 13, which can drive the circular plate 10 to move toward the stable side plate 9 and make close contact with the stable side plate 9, thereby increasing the positional stability of the platform 3.

[0027] Furthermore, a guide block 14 is slidably sleeved on the outer side of the transmission column 13, and the upper end of the guide block 14 is fixedly connected to the platform 3.

[0028] The guide block 14 can guide the translation of the transmission column 13, thereby increasing the linear stability of the translation of the transmission column 13.

[0029] Working principle: When it is necessary to adjust the angle of the drilling rig beam, the piston rod of the hydraulic cylinder 6 extends and retracts, pushing the platform 3 to rotate around the shaft 15 through the upper mounting seat 5, thereby changing the angle of the beam. During this process, the helical gear 16 fixed on the shaft 15 drives the meshing helical gear 17 to rotate. The encoder 19 detects the rotation angle of gear 17 in real time. After the angle is adjusted to the correct position, the electric cylinder 802 of the support mechanism 8 can adjust the height of the top plate 803, so that the top plate 804 contacts the platform 3, providing auxiliary support for the platform 3. At the same time, the electric cylinder 12 drives the circular plate 10 to move through the transmission column 13 until it is tightly fitted with the stabilizing side plate 9, increasing the stability of the platform position, thus facilitating the accurate angle adjustment of the horizontal directional drilling rig beam.
