For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0024] like Figure 1-Figure 3As shown, a shaft fixing device during the construction of a structural layer in a preferred embodiment of the utility model includes a support assembly, a connecting assembly and a fixing member 106. The support assembly is arranged below the connecting assembly and is detachably connected to the connecting assembly. The fixing member 106 is connected to one end of the support assembly away from the connecting assembly by screws.

[0025] In this preferred embodiment, the support assembly includes a plurality of support members and control members;

[0026] The control component includes an upper control panel 104 and a lower control panel 105 . An extension block 109 is provided on one side of the upper control panel 104 close to the lower control panel 105 . A support block 110 is provided on one side of the lower control panel 105 close to the upper control panel 104 . The support arm 107 is connected to the control component via the support block 110 .

[0027] It can be understood that the shaft fixing device during the structural layer construction process of the present invention includes three main parts: a support assembly, a connection assembly and a fixing member 106. This design allows the support assembly to be located below the connection assembly and connected in a detachable manner, so that the fixing member 106 can be fixed to one end of the support assembly by screws, thereby achieving the fixation of the shaft. The complexity of the support assembly lies in that it includes multiple support members and control members, which include an upper control panel 104 and a lower control panel 105. The upper control panel 104 and the lower control panel 105 are connected by an extension block 109 and a support block 110, so that the support member can be connected to the control member, thereby providing an adjustable fixing method to accommodate shafts of different diameters.

[0028] In this preferred embodiment, the support member includes a support arm 107 and an extension arm 111;

[0029] One end of the support arm 107 is connected to the support block 110 by a thread, one end of the extension arm 111 is connected to the extension block 109 by a thread, and the end of the extension arm 111 away from the extension block 109 is connected to the end of the support arm 107 away from the support block 110 by a thread, and the fixing member 106 is connected to the extension arm 111 by a thread.

[0030] In this preferred embodiment, the support arm 107 is in a U-shaped structure, and the opening faces the extension arm 111 . The extension arm 111 is disposed inside the U-shaped opening and connected to the support arm 107 via threads.

[0031] In this preferred embodiment, a limiting member 108 is disposed on one side of the fixing member 106 close to the supporting arm 107 , and the fixing member 106 is connected to the supporting arm 107 via the limiting member 108 .

[0032] It is understandable that the design of the support arm 107 includes two parts: the support arm 107 and the extension arm 111. The two parts are connected by threads, so that the entire support assembly can be extended and retracted as needed to adapt to different diameters of the wellbore. The connection between the fixing member 106 and the extension arm 111 further enhances the stability of the fixation. The U-shaped structure of the support arm 107 provides a stable support for the extension arm 111, and the design of the opening toward the extension arm 111 enables the extension arm 111 to be located inside the U-shaped opening and connected by threads. This structure improves the stability and reliability of the entire fixing device. A limiting member 108 is provided on one side of the fixing member 106 close to the support arm 107, which helps to ensure that the position of the fixing member 106 on the support arm 107 is fixed to prevent displacement during use, thereby improving the safety of the fixation.

[0033] In this preferred embodiment, the upper control disk 104 and the lower control disk 105 are both circular and have the same diameter, and through holes of the same size are disposed in the center of the upper control disk 104 and the lower control disk 105 .

[0034] In this preferred embodiment, the connecting assembly includes a screw 102 and a connecting rod 101, a rotating disk is arranged below the connecting rod 101, a limiting hole with the same size as the through hole is arranged at the center of the rotating disk, the screw 102 passes through the connecting piece through the limiting hole, and a limiting nut is arranged above the rotating disk, the limiting nut matches the screw 102, a wrench head 103 matching the nut is arranged above the rotating disk, the wrench head 103 is welded to the rotating disk below, and the connecting rod 101 is welded to the rotating disk below.

[0035] In this preferred embodiment, a side of the connecting rod 101 close to the screw rod 102 is configured to be semicircular, and a diameter of the connecting rod 101 is greater than a diameter of the screw rod 102 .

[0036] It is understood that the circular design of the upper control disk 104 and the lower control disk 105, as well as the through hole set in their center, provide a stable connection point for the connection assembly, while also facilitating assembly and adjustment. The design of the connection assembly includes a screw 102, a connecting rod 101, a rotating disk, a limit nut and a wrench head 103. The combination of these components enables the user to easily adjust the fixture through the rotating disk and the wrench head 103 to adapt to different diameters and fixing requirements of the wellbore. The semicircular design and larger diameter of the connecting rod 101, as well as its connection with the screw 102, provide a sturdy and easy-to-operate connection method, further enhancing the stability and durability of the entire fixture.

[0037] In summary, the present application provides a solution with a simple structure, convenient installation and good fixing effect. The device includes a support assembly, a connecting assembly and a fixing member 106, so that the device can be firmly fixed on the wellbore and can adapt to wellbores of different diameters. The support assembly includes a plurality of support arms 107 and a control member, so that the device can better disperse the weight of the wellbore, thereby improving the fixing effect. The connecting assembly includes a screw 102 and a connecting rod 101, so that the device can be easily connected and disassembled from the wellbore. In addition, the device also has a limiter 108 to ensure the stability and reliability of the fixing member 106. Therefore, the wellbore fixing device during the construction of the structural layer can meet the fixing requirements of wellbores of different diameters and has a wide range of application prospects. At the same time, it avoids the construction materials around the well wall from being insufficiently compacted due to the loose fixation of the wellbore during the compaction process, thereby causing construction problems such as sinking and cracks, and improves the rolling and compaction quality of the structural layer around the wellbore, and the compaction meets the specification requirements.

[0038] Furthermore, in other preferred embodiments, a rubber sheet 112 is also provided on the outside of the fixing part 106, and the materials can be selected from 5mm thick steel plate, 30mm diameter steel pipe, 5mm thick rubber sheet, and 25mm diameter screw 102. The nut on the screw 102 can be loosened or tightened by the connecting rod 101, and pressure can be generated on the support arm 107, so that the fixing part 106 is firmly attached to the well wall. At the same time, the support arm 107 can be adjusted to act on wells of different diameters. The fixing part 106 can be rotated up and down and moved horizontally to adapt to wells of different diameters. In addition, the rubber sheet is bonded to the bottom surface of the fixing part 106 to increase the friction between the fixing part 106 and the well wall to prevent damage to the well wall. A rotating disk is welded at the bottom of the connecting rod 101, which can be connected to the bottom opening lifting device. A groove is opened at the joint with the screw 102 to facilitate the disassembly of the steel pipe.

[0039] In this way, by loosening the nut on the screw 102 of the connecting rod 101, the user can apply pressure to the support arm 107 so that the fixing part 106 fits tightly against the well wall. This design can not only firmly fix the wellbore, but also adapt to wellbores of different diameters, providing excellent flexibility and adaptability. The rubber sheet bonded to the bottom surface of the fixing part 106 increases the friction between the fixing part 106 and the well wall, which helps to prevent the fixing part 106 from damaging the well wall when moving in the wellbore, thereby protecting the integrity of the well wall. The rotating disk welded at the bottom of the connecting rod 101 is designed to dock with the opening lifting device at the bottom for easy installation and disassembly. In addition, the slotted design at the junction with the screw 102 makes it easier to disassemble the steel pipe, thereby reducing the difficulty of maintenance and replacement.

[0040] The working process of the utility model is as follows: it is only necessary to place the upper wellbore 2 in advance, lift the device by one person, put it into the wellbore to the joint of the upper wellbore 2 and the lower wellbore 1, let the fixing part 106 be located at the center of the joint, and the lifting person rotates the connecting rod 101, tightens the top nut of the screw 102 to increase the pressure of the fixing part 106 on the wellbore wall, and fixes the wellbore. Then move the handle at the end of the steel pipe to the rear to complete the fixation of the upper and lower wellbores. At the same time, cover the wellhead with a customized circular steel plate to prevent backfill from entering the well during the tamping process. At the same time, it avoids the construction materials around the wellbore from being insufficiently compacted during the compaction process due to the loose fixation of the wellbore, thereby causing construction problems such as subsidence and cracks, and improves the rolling and compaction quality of the structural layer around the wellbore, and the compaction degree meets the specification requirements.

[0041] In summary, the embodiment of the utility model provides a shaft fixing device during the construction of a structural layer. Through the adjustable design of the support assembly, the device can adapt to shafts of different diameters, providing great flexibility. This allows the same fixing device to be used for shafts of various sizes, reducing the number and cost of different fixing devices required. The design of the connecting assembly, especially the combination of the rotating disk, the limit nut and the wrench head, enables the user to easily adjust the fixing device, quickly adapt to the diameter change of the shaft, simplify the installation and adjustment process, and improve work efficiency. The U-shaped structure of the support arm and the design of the extension arm enhance the stability of the fixing device, and the use of the limiter further ensures the fixed position of the fixing member on the support arm, reducing the risk of displacement during use, thereby improving the safety and reliability of the fixation. The semicircular design and larger diameter of the connecting rod, as well as the firm connection with the screw, enhance the durability of the fixing device. At the same time, this design is also convenient for maintenance and replacement, reducing maintenance costs. Moreover, due to its reliable, flexible and easy-to-adjust characteristics, the shaft fixing device during the construction of the structural layer of the present invention is suitable for various industrial and construction applications, especially in environments where the fixing device needs to be frequently replaced or adjusted, which can significantly improve work efficiency and safety.

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
