Description

Technical Field

[0001] This utility model relates to the field of drilling mast technology, and in particular to a drilling mast structure. Background Technology

[0002] The drilling mast is an important component of a drilling rig. It is typically a vertical rod-like structure on the rig used to support and guide drilling tools such as drill rods and drill bits, and to provide vertical guidance for drilling operations. The mast provides support and guidance for the drilling, lifting, and lowering of the drill rods and drill bits, ensuring that the drill rods can be drilled vertically and guaranteeing the verticality and accuracy of the borehole. At the same time, it also bears the weight of the drill string. During the tripping process, the lifting force of the drilling rig is transmitted to the drill rods and drill bits through pulleys, wire ropes, and other devices, realizing the raising and lowering movement of the drill string.

[0003] In daily work, it has been found that existing drilling rig masts mainly rely on hydraulic cylinders for support and adjustment to control the drill head for drilling operations. However, during operation, it is difficult to effectively resist various forces generated during drilling, including drill bit vibration and reaction forces caused by formation resistance, resulting in mast swaying. Mast swaying not only reduces drilling accuracy and causes deviations in the drilled hole, but also affects the quality of the project. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of unstable mast swaying in the existing technology, which reduces the accuracy of drilling and affects the quality of the project, and to propose a drilling rig mast structure.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a drilling mast structure, including a mast body, a guide portion on one side of the mast body, a slide rail on the surface of the mast body, and a stabilizing device on the surface of the mast body. The stabilizing device includes a rotating sleeve rotatably connected to both sides of the mast body. A fixing frame is fixedly connected to the surface of the rotating sleeve, and a hydraulic cylinder is fixedly connected to the surface of the fixing frame. A hollow frame is fixedly connected to the output end of the hydraulic cylinder, and a motor is fixedly connected to the inner wall of the hollow frame. A drill rod is provided on one side of the motor, and a support member is fixedly connected to the surface of the drill rod. An installation portion is provided between the drill rod and the output end of the motor, and an angle adjustment portion is provided between the mast body and the rotating sleeve. Through these components, during use, after the mast body is adjusted, the angle adjustment portion drives the rotating sleeve and the drill rod to rotate, ensuring the drill rod is perpendicular to the ground. Subsequently, the hydraulic cylinder drives the hollow frame and the drill rod to move, and the motor drives the drill rod to rotate, allowing the drill rod to drill into the ground and cooperate with the support member, thereby reinforcing and supporting the mast body and improving stability.

[0006] Preferably, the angle adjustment part includes a gear fixed on the surface of the rotating sleeve, and two hydraulic cylinders are fixedly connected to the inner wall of the mast body. The output end of the hydraulic cylinder is fixedly connected to a control gear, which meshes with the gear. By opening the hydraulic cylinder, the hydraulic cylinder can drive the control gear to move, and the control gear, in conjunction with the gear, can drive the rotating sleeve to rotate, thereby adjusting the position.

[0007] Preferably, the control tooth includes a plate and two racks, the two racks being fixed on the surface of the plate and arranged perpendicularly to the plate.

[0008] Preferably, the support member is circular in shape. By using the above-mentioned components, the circular support member can be in contact with the ground, which can improve the overall stability and contact area.

[0009] Preferably, the mounting part includes a mounting sleeve fixed to the motor output end, a mounting block fixedly connected to one end of the drill rod, the mounting block being inserted into the inner wall of the mounting sleeve, a threaded rod being inserted into the inner wall of the mounting sleeve, and the threaded rod being inserted into the inner wall of the mounting block. Through the above components, after the mounting block is inserted into the mounting sleeve, the threaded rod can be inserted into the inner walls of the mounting sleeve and the mounting block to complete the connection, which facilitates the replacement of the drill rod.

[0010] Preferably, a threaded sleeve is fixedly connected to the surface of the mounting sleeve, and the threaded rod is threadedly connected to the inner wall of the threaded sleeve. Through the above-mentioned components, the threaded rod and the threaded sleeve cooperate to improve the stability of the threaded rod.

[0011] Preferably, the mounting block is square in shape.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] In this invention, a stabilizing device is installed, and the angle of the drill rod is adjusted by the angle adjustment part to make it perpendicular to the ground. Then, the hydraulic cylinder drives the hollow frame and the drill rod to move, and the motor drives the drill rod to rotate, so that the drill rod drills into the ground. With the support component, it fits into the ground and reinforces and supports the mast body from below, which greatly enhances the stability of the mast body. This changes the traditional method of relying solely on the mast's own structure for support and can effectively reduce the swaying of the mast during operation and the forces acting in all directions.

[0014] In this invention, by setting an installation part, the installation block is inserted into the installation sleeve, and the drill rod is fixed by the cooperation of the threaded rod and the threaded sleeve. When replacement is needed, the installation block can be easily removed by rotating the threaded rod, which facilitates quick replacement of the drill rod and support components.

[0022] Please see Figures 1-5 This utility model provides a technical solution: a drilling rig mast structure, including a mast body 1, a guide part 2 provided on one side of the mast body 1, a slide rail 3 provided on the surface of the mast body 1, and a stabilizing device 4 provided on the surface of the mast body 1.

[0023] Specifically, the stabilizing device 4 includes a rotating sleeve 42 rotatably connected to both sides of the mast body 1. A fixing frame 43 is fixedly connected to the surface of the rotating sleeve 42. A hydraulic cylinder 41 is fixedly connected to the surface of the fixing frame 43. A hollow frame 47 is fixedly connected to the output end of the hydraulic cylinder 41. A motor 48 is fixedly connected to the inner wall of the hollow frame 47. A drill rod 45 is provided on one side of the motor 48. A support member 46 is fixedly connected to the surface of the drill rod 45. An installation part 49 is provided between the drill rod 45 and the output end of the motor 48. An angle adjustment part 44 is provided between the mast body 1 and the rotating sleeve 42.

[0024] In this implementation plan: When in use, after the mast body 1 is adjusted, the angle adjustment part 44 drives the rotating sleeve 42 and the drill rod 45 to rotate, ensuring that the drill rod 45 is perpendicular to the ground. Then, the hydraulic cylinder 41 drives the hollow frame 47 and the drill rod 45 to move, and the motor 48 drives the drill rod 45 to rotate, allowing the drill rod 45 to drill into the ground and cooperate with the support member 46, thereby reinforcing and supporting the mast body 1 and improving its stability.

[0025] Specifically, the angle adjustment unit 44 includes a gear 443 fixed on the surface of the rotating sleeve 42, and two hydraulic cylinders 441 are fixedly connected to the inner wall of the mast body 1. The output end of the hydraulic cylinders 441 is fixedly connected to a control gear 442, which meshes with the gear 443.

[0026] In this implementation scheme: when hydraulic cylinder 441 is opened, hydraulic cylinder 441 can drive control gear 442 to move, and control gear 442, in conjunction with gear 443, can drive rotating sleeve 42 to rotate and adjust position.

[0027] Specifically, the control tooth 442 includes a plate 4421 and two racks 4422. The two racks 4422 are fixed on the surface of the plate 4421 and are arranged perpendicular to the plate 4421.

[0028] Specifically, the support member 46 is circular in shape. After the circular support member 46 is in contact with the ground, it can improve the overall stability and contact surface.

[0029] Specifically, the mounting part 49 includes a mounting sleeve 491 fixed to the output end of the motor 48, a mounting block 492 fixedly connected to one end of the drill rod 45, the mounting block 492 being inserted into the inner wall of the mounting sleeve 491, and a threaded rod 494 being inserted into the inner wall of the mounting sleeve 491, the threaded rod 494 being inserted into the inner wall of the mounting block 492.

[0030] In this implementation scheme: after the mounting block 492 is inserted into the mounting sleeve 491, the threaded rod 494 can be inserted into the inner wall of the mounting sleeve 491 and the mounting block 492 to complete the connection, which facilitates the replacement of the drill rod 45.

[0031] Specifically, a threaded sleeve 493 is fixedly connected to the surface of the mounting sleeve 491, and a threaded rod 494 is threadedly connected to the inner wall of the threaded sleeve 493.

[0032] In this implementation scheme, the threaded rod 494 and the threaded sleeve 493 are fitted together to improve the stability of the threaded rod 494.

[0033] Preferably, the mounting block 492 is arranged in a square shape.

[0034] Working principle: During operation, after the drilling rig adjusts the mast body 1, hydraulic cylinder 2 441 is opened. Hydraulic cylinder 2 441 moves the control gear 442, which, in conjunction with gear 443, rotates the rotating sleeve 42. After adjusting the drill rod 45 to be perpendicular to the ground, hydraulic cylinder 1 41 and motor 48 are opened. Hydraulic cylinder 1 41 moves the hollow frame 47 and drill rod 45, while motor 48 rotates the drill rod 45, allowing it to drill into the ground and fit in contact with the support component 46, thereby reinforcing and supporting the mast body 1 and improving stability. When it is necessary to replace the drill rod 45 and the support component 46, simply rotate the threaded rod 494 to remove it from the threaded sleeve 493, and then pull the threaded rod 494 out of the inner wall of the mounting block 492. The mounting block 492 can then be removed from the mounting sleeve 491 for replacement.
