Description

Technical Field

[0001] The utility model relates to the technical field of drilling frames, in particular to a drilling frame which can be moved as a whole. Background Art

[0002] In the process of geothermal energy development, multiple production wells need to be drilled from the ground to the underground. At present, drilling wells are generally drilled by drilling rigs in the process of geothermal energy development. Traditional drilling rigs include drilling frames, drive modules, drilling fluid circulation modules, etc. The drilling frames are large in size, and their various components need to be transported to designated locations by transport vehicles and assembled on site. After completing one drilling, they need to be disassembled and transported to another location where drilling is required and reassembled to complete the second drilling. During the drilling process, the drilling frame of the drilling rig needs to be disassembled and assembled many times, which greatly reduces the drilling efficiency of the production wells.

[0003] According to the Chinese utility model disclosure CN218407306U, a drilling rig that can be moved as a whole is disclosed, including a drilling mounting bracket assembly, a circular frame is provided below the drilling mounting bracket assembly, and the four corners of the top of the circular frame are fixedly connected to hydraulic cylinders. The top ends of the output shafts of the four hydraulic cylinders are fixedly connected to the bottom of the drilling mounting bracket assembly. The four hydraulic cylinders can drive the entire drilling mounting bracket assembly to move upward, and two bases are provided below the circular frame. The utility model facilitates personnel to move the entire device by providing multiple running wheels, eliminating the need for dismantling operations. The elastic drive mechanism and the extrusion rod can be provided to synchronously store multiple running wheels, increase the support friction area, improve placement stability, and effectively reduce the risk of displacement during use. The sliding drive mechanism can automatically drive the drilling mounting bracket assembly and the drilling equipment thereon to move forward and backward without the need for external pulling, thereby reducing labor intensity.

[0004] This utility model has a poor shock absorption effect when the drilling rig is moved, which easily causes the equipment on the top of the drilling rig to be greatly bumped when the drilling rig is moved, thereby being damaged and reducing the service life. In order to solve this problem, the utility model proposes a drilling rig that can be moved as a whole. Utility Model Content

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] Example 1

[0042] See Figure 1-3 A drilling rig that can be moved as a whole includes a frame assembly 1, including: a moving frame 11, on which a drilling rig 12 is arranged, a moving assembly 2 is arranged at the bottom of the moving frame 11, and the moving assembly 2 includes: a rotating rod 21, which is symmetrically and rotationally connected to the inner wall of the moving frame 11, a connecting block 22, which is symmetrically and fixedly connected to the outside of the rotating rod 21, a spring shock absorber 23, which is arranged at the bottom of the connecting block 22, a through groove for the spring shock absorber 23 to move is provided inside the moving frame 11, a universal wheel 24, which is arranged at the bottom of the spring shock absorber 23, and a driving mechanism 25, which is arranged on the moving frame 11. The driving mechanism 25 includes: a motor 251, whose output end passes through and is rotatably connected to the right side wall of the moving frame 11; a rotating shaft 252, which is fixedly connected to the output end of the motor 251; a bevel gear 1 253, which is symmetrically arranged on the outside of the rotating shaft 252; a bevel gear 254, which is symmetrically arranged on the outside of the rotating rod 21, and the bevel gear 254 is meshed with the bevel gear 1 253. A support mechanism 26 is provided on the moving frame 11 and the rotating rod 21. The support mechanism 26 includes: a gear 261, which is symmetrically sleeved on the outside of both ends of the rotating rod 21; a support rod 262, which is symmetrically and slidably connected to the inner wall of the moving frame 11, and the inner wall of the moving frame 11 is provided with a sliding groove for the support rod 262 to slide; and a rack 263, which is provided on the side of the support rod 262 close to the gear 261 and meshes with the gear 261. The length of the sliding groove provided on the inner wall of the movable frame 11 for the gear 261 to slide is the same as the length of the gear 261 .

[0043] When in use, the universal wheel 24 is used to realize the movement of the moving frame 11 and the drilling rig 12. The spring shock absorber 123 on the top of the universal wheel 24 is used to reduce vibration when the drilling rig 12 moves to prevent the equipment on the drilling rig 12 from being damaged by bumps. The driving mechanism 25 is used to drive the rotating rod 21 to rotate to realize the retraction of the universal wheel 24: the motor 251 is started, and the motor 251 drives the rotating shaft 252 to rotate. The two bevel gears 1 253 on the rotating shaft 252 rotate, and the bevel gear 2 254 meshing with the bevel gear 1 253 drives the rotating rod 21 to rotate in the opposite direction at the same time under the rotation of the bevel gear 1 253. The rotating rod 21 drives the connecting block 22 and the universal wheel 24 to rotate in the opposite direction, and the universal wheel 24 is retracted into the moving frame 11. At the same time, when the rotating rod 21 rotates, the linkage support mechanism 26 supports the moving frame 11: the rotating rod 21 drives the gear 261 to rotate, and the rack 263 engaged with the gear 261 drives the support rod 262 to descend. The speed at which the support rod 262 descends is the same as the speed at which the universal wheel 24 is retracted. When the universal wheel 24 is retracted, the support rod 262 supports the moving frame 11. At the same time, the reversing motor 251 realizes the extension of the universal wheel 24 and the retraction of the support rod 262, which facilitates the further movement of the drilling rig 12. The support rod 262 has the same length as the slide groove opened in the moving frame 11, so that the support rod 262 can be completely retracted into the moving frame 11 to avoid affecting the movement of the universal wheel 24.

[0044] Example 2

[0045] On the basis of the first embodiment, an auxiliary function is added.

[0046] See Figure 1-3 The bottom end of the gear 261 is externally slidably connected to a support frame 264. A second spring damper 265 is disposed between the bottom end of the rack 263 and the top surface of the support frame 264. Corresponding through-holes are formed in the rack 263 and the support frame 264, and a bolt 266 is threadedly connected within the through-hole. The second spring damper 265 allows the support rod 262 to move and buffer within the support frame 264 during descent, thereby increasing the stability of the drilling rig 12. When the support rod 262 completes its supporting action, the bolt 266 is rotated into the support frame 264 and the support rod 262 to secure the support rod 262. An anti-skid pad 3 is disposed at the bottom end of the support frame 264. The anti-skid pad 3 increases the contact area between the support rod 262 and the ground, improving stability and preventing movement of the drilling rig 12 during drilling activities. A baffle 4 is provided on the left inner wall of the movable frame 11, and the right side of the baffle 4 abuts against the left end of the connecting block 22. The baffle 4 limits the range of movement of the connecting block 22 and the universal wheel 24 to prevent the universal wheel 24 from rotating too much, affecting the normal retraction and extension of the universal wheel 24, thereby affecting its normal use.
