Description

Technical Field

[0001] The present invention relates to the technical field of anchor bolts, and particularly to a detachable anchor bolt. Background Art

[0002] The anchor bolts of machine tool equipment play a role in fixing the equipment and adjusting the precision positioning. During the overall disassembly and hoisting repair of the gearbox of a three-meter vertical lathe for machining, the gearbox is connected to the bed guide rail and weighs about 5 tons. It is fixed by six anchor bolts. When these anchor bolts were installed initially, the precision was adjusted and then grouted for fixation. During disassembly, since a part of the transmission gears inside the gearbox extends out of the gearbox (meshes with the machine tool gears), to remove the gearbox as a whole, the anchor bolts must be taken out, and then the bolts connecting the bed are loosened and the whole is translated outward by 200 mm to be hoisted out. Since the anchor bolts directly penetrate into the gearbox body and cannot be translated, during disassembly, the anchor bolts can only be cut off and then hoisted out for repair. This design results in the anchor bolts not being reusable, and during secondary installation, grouting fixation is still required, which involves a large amount of work and wastes time. Therefore, a detachable anchor bolt needs to be designed. Summary of the Invention

[0003] The purpose of the present invention is to provide a detachable anchor bolt to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the present invention provides the following technical solution: A detachable anchor bolt includes a bolt fixing part and a bolt disassembly part. The bolt fixing part includes a long handle section, a threaded section, and a hook section. The top end of the long handle section is welded to the threaded section, and the hook section is integrally formed with the long handle section. The bottom end of the bolt disassembly part is in threaded connection with the internal thread of the threaded section. A anti-loosening component is provided at the connection between the bolt disassembly part and the threaded section. An anchoring component is sleeved on the external thread of the threaded section. A pressing component is provided between the anti-loosening component and the anchoring component.

[0005] Further, the anti-loosening component includes a stop ring one, a threaded connection sleeve one, and a stabilizing tube. The stop ring one is fixedly installed on the bolt disassembly part and is welded to the bolt disassembly part. The threaded connection sleeve one is threadedly sleeved on the top end of the threaded section, and the inner wall of the top of the threaded connection sleeve one presses on the stop ring one. The top end of the threaded connection sleeve one is fixedly installed with the stabilizing tube. The stabilizing tube is slidably sleeved on the bolt disassembly part and passes through the installation hole on the gearbox.

[0006] Further, a connection nut is threadedly sleeved on the outer wall of the bolt disassembly part. An elastic gasket is slidably sleeved on the outer wall of the bolt disassembly part. The elastic gasket presses on the top of the stabilizing tube, and the connection nut presses on the top of the elastic gasket.

[0007] Furthermore, an integrally formed extension body is provided at the top of the stabilizing tube, and the diameter of the extension body is larger than that of the stabilizing tube.

[0008] Furthermore, the anchoring assembly includes a bowl-shaped anchoring piece and a threaded connecting pipe. The bowl-shaped anchoring piece is fixedly installed on the outer wall of the threaded connecting pipe, and the bowl-shaped anchoring piece is in a bowl shape.

[0009] Furthermore, a through groove is formed in the bowl-shaped anchoring piece, and the through groove divides the bowl-shaped anchoring piece into six equally wide anchoring pieces.

[0010] Furthermore, auxiliary anchoring pieces are fixedly installed on the outer wall of the bowl-shaped anchoring piece. There are six auxiliary anchoring pieces, which correspond to the six equally wide anchoring pieces one by one. The direction of the auxiliary anchoring pieces is opposite to that of the bowl-shaped anchoring piece up and down.

[0011] Furthermore, the pressing assembly includes a limiting ring, a second threaded connecting sleeve, and a sliding ring. The limiting ring is fixedly installed on the threaded section. The second threaded connecting sleeve is threadedly sleeved on the threaded section and is slidably sleeved on the limiting ring. The sliding ring is slidably sleeved on the threaded section. A top pressing piece is fixedly installed at the bottom of the sliding ring, and the bottom end of the top pressing piece presses on the inner side wall of the bowl-shaped anchoring piece.

[0012] Furthermore, there are six top pressing pieces at the bottom of the sliding ring, which correspond to the six equally wide anchoring pieces on the bowl-shaped anchoring piece one by one.

[0013] Furthermore, a second stop ring is fixedly installed on the outer wall of the long handle section, and the outer diameter of the second stop ring is the same as that of the threaded connecting pipe.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: Since the bolt disassembly component is connected to the bolt fixing part by a threaded connection method, when installing the gearbox, the gearbox can be placed in place, and then the bolt disassembly component can be installed on the bolt fixing part, and then the gearbox can be fixed. When overhauling the gearbox, the bolt disassembly component can be removed first. At this time, there is no blocking structure inside the gearbox, so the gearbox can be horizontally moved and removed from the machine tool. By pressing the first stop ring with the first threaded connecting sleeve, and then pressing the bolt disassembly component, it is possible to prevent the bolt disassembly component from disengaging from the threaded section. At the same time, the stabilizing tube matching the installation hole of the gearbox is used to stabilize the gearbox and avoid the problem of left and right offset of the gearbox. When disassembling the bolt disassembly component, the first threaded connecting sleeve can be rotated first, so that the first threaded connecting sleeve rotates and moves upward at the same time until the first threaded connecting sleeve completely disengages from the threaded section. At this time, the bolt disassembly component can be rotated to take out the bolt disassembly component from the threaded section. Six equally - wide anchoring pieces increase the contact boundary with the concrete. When the concrete solidifies after pouring, more mechanical biting points are formed between the anchoring pieces and the concrete. Compared with the complete bowl - shaped anchoring piece, the divided anchoring pieces can be embedded deeper into the concrete, greatly enhancing the frictional force and biting force between the anchor bolts and the concrete. When external forces such as vibration, horizontal tension, or vertical pressure are generated during equipment operation, these dispersed and deep - seated anchoring pieces can more effectively transfer the acting forces to the concrete foundation, thus stabilizing the anchor bolts and preventing them from loosening or displacing. The pressing component can effectively prevent the bowl - shaped anchoring piece from displacing or deforming due to external forces such as vibration and horizontal force, thereby ensuring the tight combination between the anchor bolts and the concrete foundation, improving the stability and reliability of the entire equipment. During the use of the equipment, if maintenance or adjustment of the anchor bolts is required, the pressing component also provides great convenience. By loosening or tightening the threaded connection sleeve two, construction workers can easily adjust the pressing force on the bowl - shaped anchoring piece to adapt to changes in the foundation conditions or the operating state of the equipment. If it is found that a certain component is damaged, it can also be conveniently disassembled and replaced to ensure that the anchor bolt system is always in good working condition.

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0018] Embodiment 1 Please refer to Figures 1-10 , the present invention provides a technical solution: a detachable anchor bolt, including a bolt fixing part 1 and a bolt disassembly component 2. The bolt fixing part 1 includes a long handle section 101, a thread section 102, and a hook section 103. The top end of the long handle section 101 is welded to the thread section 102, and the hook section 103 is integrally formed with the long handle section 101. The bottom end of the bolt disassembly component 2 is internally thread - connected to the thread section 102. An anti - detachment component 3 is provided at the connection between the bolt disassembly component 2 and the thread section 102. An anchoring component 4 is externally threaded on the thread section 102. A pressing component 5 is provided between the anti - detachment component 3 and the anchoring component 4. Since the bolt disassembly component 2 is connected to the bolt fixing part 1 by a threaded connection, when installing the gearbox, the gearbox can be placed in place first, and then the bolt disassembly component 2 can be installed on the bolt fixing part 1, and then the gearbox can be fixed. When overhauling the gearbox, the bolt disassembly component 2 can be removed first. At this time, there is no blocking structure inside the gearbox, so the gearbox can be horizontally moved and removed from the machine tool. The anti - detachment component 3 is provided to prevent the bolt disassembly component 2 from falling off the bolt fixing part 1. The anchoring component 4 is provided to strengthen the connection stability between the bolt fixing part 1 and the foundation (concrete foundation). The pressing component 5 is provided to compact the anchoring component 4 to avoid the problem of the anchoring component 4 rebounding; The anti - detachment component 3 includes a first stop ring 301, a first threaded connection sleeve 302, and a stabilizing tube 303. The first stop ring 301 is fixedly installed on the bolt disassembly component 2, and the first stop ring 301 is welded to the bolt disassembly component 2. The first threaded connection sleeve 302 is threadedly sleeved on the top of the threaded section 102, and the inner wall of the top of the first threaded connection sleeve 302 presses on the first stop ring 301. The top of the first threaded connection sleeve 302 is fixedly installed with a stabilizing tube 303. The stabilizing tube 303 is slidably sleeved on the bolt disassembly component 2. The stabilizing tube 303 passes through the installation hole on the gearbox. The first stop ring 301 is provided to limit the length of the bolt disassembly component 2 screwed into the threaded section 102 and provide a force - receiving point for the first threaded connection sleeve 302 to press on the bolt disassembly component 2. By pressing the first stop ring 301 with the first threaded connection sleeve 302, and then pressing the bolt disassembly component 2, it is avoided that the bolt disassembly component 2 disengages from the threaded section 102. At the same time, the gearbox is stabilized by using the stabilizing tube 303 that matches the installation hole of the gearbox, avoiding the problem of the gearbox shifting left and right. When disassembling the bolt disassembly component 2, the first threaded connection sleeve 302 can be rotated first, so that the first threaded connection sleeve 302 rotates and moves upward at the same time until the first threaded connection sleeve 302 completely disengages from the threaded section 102. At this time, the bolt disassembly component 2 can be rotated to take out the bolt disassembly component 2 from the threaded section 102; A connection nut 6 is threadedly sleeved on the outer wall of the bolt disassembly component 2, and an elastic gasket 7 is slidably sleeved on the outer wall of the bolt disassembly component 2. The elastic gasket 7 presses on the top of the stabilizing tube 303, and the connection nut 6 presses on the top of the elastic gasket 7. The connection nut 6 and the elastic gasket 7 are provided to fix the gearbox and the stabilizing tube 303 together, that is, the gearbox is fixed by the fact that the diameters of the connection nut 6 and the elastic gasket 7 are larger than the installation hole of the gearbox; An integrally formed extension body is provided at the top of the stabilizing tube 303, and the diameter of the extension body is larger than the diameter of the stabilizing tube 303, so that the elastic gasket 7 has a better contact surface, avoiding the problem of excessive bending deformation of the elastic gasket 7. At the same time, because the diameter of the extension body is larger than the diameter of the stabilizing tube 303, when installing the gearbox, it is the extension body that presses on the gearbox. Therefore, the extension body can also play a certain positioning role.

[0019] Working principle: When in use, first bury the bolt fixing part 1 into the foundation, and then fix the hook section 103 and part of the long handle section 101 on the bolt fixing part 1 by pouring concrete. Before burying the bolt fixing part 1, precise positioning is carried out first. When installing the gearbox, hoist the gearbox in place. At this time, the mounting holes on the gearbox are aligned with the threaded section 102. Pass the bolt disassembly part 2 through the mounting hole, and then rotate the bolt disassembly part 2 to screw the bottom end of the bolt disassembly part 2 into the threaded section 102 until the stop ring 301 presses on the top end of the threaded section 102. Pass the threaded connecting sleeve 302 through the mounting hole, and then align the threaded connecting sleeve 302 with the threaded section 102, and rotate the threaded connecting sleeve 302 so that the threaded connecting sleeve 302 is sleeved on the threaded section 102 until the threaded connecting sleeve 302 presses on the stop ring 301. At this time, the stabilizing tube 303 is in a state of being inserted into the mounting hole. Then place the elastic gasket 7 on the top end of the stabilizing tube 303, and screw in the connecting nut 6 to tightly fix the elastic gasket 7, thereby fixing the stabilizing tube 303.

[0020] Embodiment 2 Please refer to Figures 1-10 As shown in [reference figure], the present invention provides a technical solution: a detachable anchor bolt, including a bolt fixing part 1 and a bolt disassembly part 2. The bolt fixing part 1 includes a long handle section 101, a threaded section 102, and a hook section 103. The top end of the long handle section 101 is welded to the threaded section 102, and the hook section 103 is integrally formed with the long handle section 101. The bottom end of the bolt disassembly part 2 is internally threaded with the threaded section 102. An anti-loosening component 3 is provided at the connection between the bolt disassembly part 2 and the threaded section 102. An anchoring component 4 is sleeved on the external thread of the threaded section 102. A pressing component 5 is provided between the anti-loosening component 3 and the anchoring component 4. Since the bolt disassembly part 2 is connected to the bolt fixing part 1 by a threaded connection, when installing the gearbox, the gearbox can be placed in place first, and then the bolt disassembly part 2 can be installed on the bolt fixing part 1, and then the gearbox can be fixed. When overhauling the gearbox, the bolt disassembly part 2 can be removed first. At this time, there is no blocking structure inside the gearbox, so the gearbox can be horizontally moved and removed from the machine tool. The anti-loosening component 3 is provided to prevent the bolt disassembly part 2 from falling off the bolt fixing part 1. The anchoring component 4 is provided to strengthen the connection stability between the bolt fixing part 1 and the foundation (concrete foundation). The pressing component 5 is provided to compact the anchoring component 4 to avoid the problem of the anchoring component 4 rebounding; The anti-loosening component 3 includes a first stop ring 301, a first threaded connection sleeve 302, and a stabilizing tube 303. The first stop ring 301 is fixedly installed on the bolt disassembly component 2 and is welded to the bolt disassembly component 2. The first threaded connection sleeve 302 is threadedly sleeved on the top end of the threaded section 102, and the inner wall of the top of the first threaded connection sleeve 302 presses on the first stop ring 301. A stabilizing tube 303 is fixedly installed at the top end of the first threaded connection sleeve 302. The stabilizing tube 303 is slidably sleeved on the bolt disassembly component 2 and passes through the mounting hole on the gearbox. A connection nut 6 is threadedly sleeved on the outer wall of the bolt disassembly component 2. An elastic gasket 7 is slidably sleeved on the outer wall of the bolt disassembly component 2. The elastic gasket 7 presses on the top of the stabilizing tube 303, and the connection nut 6 presses on the top of the elastic gasket 7. An integrally formed extension body is provided at the top of the stabilizing tube 303, and the diameter of the extension body is larger than the diameter of the stabilizing tube 303. The anchoring component 4 includes a bowl-shaped anchoring piece 401 and a threaded connection pipe 402. The bowl-shaped anchoring piece 401 is fixedly installed on the outer wall of the threaded connection pipe 402. The bowl-shaped anchoring piece 401 is bowl-shaped. The threaded connection pipe 402 is provided for connecting the bowl-shaped anchoring piece 401 to the threaded section 102 and can also adjust the position of the bowl-shaped anchoring piece 401 up and down. One of the main functions of the bowl-shaped anchoring piece 401 is to significantly increase the contact area between the bolt fixing part 1 and the concrete. When concrete pouring operation is carried out, the bowl-shaped surface of the bowl-shaped anchoring piece 401 is in full contact with and tightly combined with the concrete. Compared with the traditional anchor bolt anchoring method for foundation bolts, this design greatly improves the frictional force and mechanical biting force between the anchor bolt and the concrete, and can more effectively transfer various acting forces generated during the operation of the equipment, such as the vertical gravity, horizontal tensile force, and shear force, etc., evenly to the concrete foundation, thus playing a more stable fixing role for the bolt fixing part 1 and ensuring the stability and safety of the entire equipment during long-term operation. In addition, the bowl-shaped shape of the bowl-shaped anchoring piece 401 also endows it with a unique shielding and intercepting function. During the concrete pouring process, it is inevitable that the concrete will flow and splash. The bowl-shaped anchoring piece 401 can effectively shield the threaded section 102 below like a small protective shield. Its bowl-shaped structure can intercept some of the splashed concrete and prevent the concrete from directly covering and submerging the threaded section 102. Once the threaded section 102 is submerged by the concrete, it will not only affect the subsequent disassembly operation of the foundation bolt, but also may cause thread damage, reducing the service life and connection reliability of the foundation bolt. Therefore, this shielding and intercepting function of the bowl-shaped anchoring piece 401 is of great significance for ensuring the normal use and maintenance of the foundation bolt, further enhancing the practicability and reliability of the entire detachable foundation bolt design. The bowl-shaped anchor piece 401 is provided with a through groove, and the through groove divides the bowl-shaped anchor piece 401 into six equally wide anchor pieces. From the perspective of enhancing the anchoring force, the six equally wide anchor pieces increase the contact boundary with the concrete. When the concrete is poured and solidified, more mechanical bite points are formed between the anchor pieces and the concrete. Compared with the complete bowl-shaped anchor piece 401, the divided anchor pieces can be more deeply embedded into the interior of the concrete, greatly enhancing the frictional force and bite force between the anchor bolts and the concrete. When external forces such as vibration, horizontal tension or vertical pressure are generated during the operation of the equipment, these dispersed and deep anchor pieces can more effectively transfer the acting force to the concrete foundation, thus stabilizing the anchor bolts and preventing them from loosening or displacing. Moreover, during the process of concrete hardening and shrinkage, the through groove allows the concrete to have a certain deformation space, reducing the risk of debonding between the anchor piece and the concrete caused by shrinkage stress, and further enhancing the bonding stability between the two. In terms of the convenience of installation and adjustment, the divided anchor pieces are relatively more flexible. When the anchor bolts need to be finely adjusted in angle or position during the installation process, these independent anchor pieces can each undergo slight deformation to a certain extent to adapt to the adjustment requirements, rather than being difficult to adjust due to excessive rigidity like the integral bowl-shaped anchor piece. This enables the construction personnel to more easily install the anchor bolts in the precise position, improving the installation efficiency and quality; Six auxiliary anchoring pieces 9 are fixedly installed on the outer wall of the bowl-shaped anchoring piece 401. The six auxiliary anchoring pieces 9 correspond one by one to six anchoring pieces of equal width, and the direction of the auxiliary anchoring piece 9 is opposite to that of the bowl-shaped anchoring piece 401 up and down. When the equipment is running, the anchor bolts will bear the acting forces from different directions, such as the gravity in the vertical direction, the tensile force and shear force in the horizontal direction, etc. The six auxiliary anchoring pieces 9 correspond one by one to six anchoring pieces of equal width, and the direction is opposite to that of the bowl-shaped anchoring piece 401 up and down, forming a mutually restrictive anchoring structure. In the vertical direction, the auxiliary anchoring piece 9 can share part of the downward pressure generated by the gravity of the equipment, cooperate with the bowl-shaped anchoring piece 401 below, and disperse the gravity more evenly into a larger range of concrete foundation. When facing the acting force in the horizontal direction, the auxiliary anchoring piece 9 and the anchoring piece of equal width cooperate with each other to generate greater anti-pulling and anti-shearing capabilities. When there is a horizontal tensile force acting on the anchor bolt, the frictional force between the auxiliary anchoring piece 9 and the concrete and the mechanical biting force formed by its embedding in the concrete will jointly resist the horizontal tensile force with the corresponding acting forces of the equal-width anchoring piece below, preventing the anchor bolt from being pulled out or having a horizontal displacement. This setting method of the anchoring pieces with opposite directions up and down is like constructing a stable "anchoring matrix" in the concrete foundation, greatly improving the stability of the anchor bolt under complex stress conditions. During the solidification process of the concrete, the auxiliary anchoring piece 9 will form a closer bond with the surrounding concrete. Its unique direction makes the concrete generate an additional extrusion effect on the auxiliary anchoring piece 9 when it hardens and shrinks, further enhancing the bonding force between the two. This enhanced bonding force not only helps to improve the anchoring performance of the anchor bolt, but also can, to a certain extent, prevent moisture and harmful substances from infiltrating into the anchoring part, protect the anchor bolt from corrosion, and extend its service life; The pressing assembly 5 includes a limit ring 501, a second threaded connecting sleeve 502, and a sliding ring 503. The limit ring 501 is fixedly installed on the threaded section 102. The second threaded connecting sleeve 502 is threadedly sleeved on the threaded section 102, and the second threaded connecting sleeve 502 is slidably sleeved on the limit ring 501. The sliding ring 503 is slidably sleeved on the threaded section 102. A pressing piece 504 is fixedly installed at the bottom of the sliding ring 503. The bottom end of the pressing piece 504 presses against the inner side wall of the bowl-shaped anchoring piece 401. The limit ring 501 is firmly installed on the threaded section 102. As a position marking point, it provides a reference for the installation and adjustment of subsequent components. During the installation process, the second threaded connecting sleeve 502 and the sliding ring 503 are assembled with reference to the limit ring 501, ensuring the accurate relative positions of the components on the threaded section 102, and avoiding problems such as uneven pressing or failure caused by the deviation of the component installation positions. The second threaded connecting sleeve 502 is threadedly sleeved on the threaded section 102 and can slide on the limit ring 501. By rotating the second threaded connecting sleeve 502, construction workers can adjust its position on the threaded section 102 according to actual needs. During the adjustment process, the second threaded connecting sleeve 502 gradually approaches the sliding ring 503, applying an axial pressure to the sliding ring 503. This pre-tightening adjustment function enables the pressing assembly 5 to adapt to different foundation conditions and installation requirements, ensuring that an appropriate pressing force can be applied to the bowl-shaped anchoring piece 401 in various situations and improving the stability of the anchor bolt. Through the pressing of the bowl-shaped anchoring piece 401 by the pressing assembly 5, the anchoring stability of the anchor bolt is further enhanced. During the concrete pouring process, the bowl-shaped anchoring piece 401 can better resist the flowing impact force of the concrete and maintain its position in the foundation unchanged. During equipment operation, the pressing assembly 5 can effectively prevent the bowl-shaped anchoring piece 401 from displacing or deforming due to external forces such as vibration and horizontal force, thereby ensuring the close combination between the anchor bolt and the concrete foundation and improving the stability and reliability of the entire equipment. During the use of the equipment, if maintenance or adjustment of the anchor bolt is required, the pressing assembly 5 also provides great convenience. By loosening or tightening the second threaded connecting sleeve 502, construction workers can easily adjust the pressing force on the bowl-shaped anchoring piece 401 to adapt to changes in foundation conditions or changes in the equipment operation state. If it is found that a certain component is damaged, it can also be easily disassembled and replaced to ensure that the anchor bolt system is always in good working condition; There are six pressing pieces 504 at the bottom of the sliding ring 503, which correspond one by one to the six equal-width anchoring pieces on the bowl-shaped anchoring piece 401. This uniform corresponding method ensures that the pressing force received by the bowl-shaped anchoring piece 401 is uniform in the circumferential direction. If the pressing force distribution is uneven, it will cause excessive local stress on the bowl-shaped anchoring piece 401, which may lead to deformation or even damage, affecting the anchoring effect of the anchor bolt. However, the uniform pressing force distribution can keep the bowl-shaped anchoring piece 401 in a stable shape and position in the concrete, giving full play to its role in enhancing the anchoring force. The pressing piece 504 corresponds one by one to the equal-width anchoring piece. After the concrete solidifies, multiple independent and cooperating mechanical biting areas are formed between the two and the concrete. When various external forces are generated during the operation of the equipment, these mechanical biting areas can work together to more effectively transfer the external forces into the concrete foundation, thus significantly enhancing the anchoring effect of the anchor bolt in the concrete foundation; A second stop ring 8 is fixedly installed on the outer wall of the long handle section 101. The outer diameter of the second stop ring 8 is the same as the outer diameter of the threaded connection pipe 402. During the installation process, the same outer diameter of the second stop ring 8 and the threaded connection pipe 402 can provide an accurate positioning reference for the installation of the anchoring assembly 4. Installers can quickly and accurately install the bowl-shaped anchoring piece 401 and the threaded connection pipe 402 to the appropriate positions by observing the positional relationship between the second stop ring 8 and the threaded connection pipe 402, ensuring the installation accuracy of the entire anchoring system, reducing installation errors, and improving installation efficiency. When the threaded connection pipe 402 is threadedly connected to the threaded section 102 on the long handle section 101, the second stop ring 8 can play a limiting role to prevent the threaded connection pipe 402 from being screwed into the threaded section 102 excessively. Excessive screwing in may cause the position of the bowl-shaped anchoring piece 401 to be too close to the bottom of the long handle section 101, affecting its contact effect and anchoring performance with the concrete, while the second stop ring 8 can effectively avoid this situation.

[0021] Working principle: When in use, before pouring the mixed soil, screw the threaded connecting pipe 402 onto the threaded section 102 until the bottom end of the threaded connecting pipe 402 presses against the second stop ring 8. Then slide the sliding ring 503 sleeved on the threaded section 102. At this time, align the pressing piece 504 at the bottom of the sliding ring 503 with the six equal-width anchoring pieces one by one, and then screw in the second threaded connecting sleeve 502 to press the sliding ring 503 downward until the specified requirements are met. At this time, pour the mixed soil below the bowl-shaped anchoring piece 401. When pouring, block the through groove on the bowl-shaped anchoring piece 401, and remove the blocking object in the through groove after the concrete solidifies. When installing the gearbox, hoist the gearbox in place. At this time, the mounting holes on the gearbox are aligned with the threaded section 102. Pass the bolt disassembly component 2 through the mounting holes, and then rotate the bolt disassembly component 2 to screw the bottom end of the bolt disassembly component 2 into the threaded section 102 until the first stop ring 301 presses against the top end of the threaded section 102. Pass the first threaded connecting sleeve 302 through the mounting holes, and then align the first threaded connecting sleeve 302 with the threaded section 102 and rotate the first threaded connecting sleeve 302 so that the first threaded connecting sleeve 302 is sleeved on the threaded section 102 until the first threaded connecting sleeve 302 presses against the first stop ring 301. At this time, the stabilizing pipe 303 is in a state of being inserted into the mounting hole. Then place the elastic gasket 7 on the top end of the stabilizing pipe 303 and screw in the connecting nut 6 to press and fix the elastic gasket 7, thereby fixing the stabilizing pipe 303.
