[0026] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Example: Please refer to Figures 1-4 This utility model provides a technical solution: a hydraulic nut locking device for confined spaces, comprising:

[0028] A reaction bucket 1, wherein a clamping groove 2 is provided on the reaction bucket 1;

[0029] Pressure rod 3 is rotatably mounted on the reaction barrel 1, and a clamping space is provided between the first end of the pressure rod 3 and the clamping groove 2;

[0030] The driving component 4 is disposed on the reaction barrel 1. When the output end of the driving component 4 drives the second end of the pressure rod 3 to move in the first direction, the first end of the pressure rod 3 moves in the second direction. The first direction and the second direction are opposite.

[0031] Specifically, the bottom of the reaction barrel 1 has a clamping groove 2, which ensures precise alignment between the equipment and the nut. A pressure rod 3 is rotatably mounted on the reaction barrel 1. The clamping space formed between the first end of the pressure rod 3 and the clamping groove 2 allows the first end of the pressure rod 3 to act on the edge of the nut during edge-locking operations, causing localized plastic deformation and achieving locking. A drive assembly 4 is mounted on the reaction barrel 1 to drive the pressure rod 3. When the output end of the drive assembly 4 moves the second end of the pressure rod 3 in the first direction, according to the lever principle, the first end of the pressure rod 3 will simultaneously move in the opposite second direction, thereby applying a compressive force to the edge of the nut.

[0032] In use, the operator first aligns the clamping groove 2 of the reaction barrel 1 with the nut, using the clamping groove 2 to position the nut. Then, the drive assembly 4 is activated, which drives the second end of the pressure rod 3 to move. At this time, the pressure rod 3 rotates on the reaction barrel 1, and the first end of the pressure rod 3 moves into the clamping groove 2, squeezing the edge of the nut. The edge of the nut undergoes localized plastic deformation, achieving a secure lock. In this device, the reaction barrel 1 and the pressure rod 3, which apply pressure to the nut, occupy a small space, enabling the locking operation of the nut in a confined space.

[0033] Among them, the reaction bucket 1 is a cylindrical structure with a clamping groove 2 at its bottom. The pressure rod 3 is installed on one side of the reaction bucket 1. Its structure is simple and occupies little space. When the driving component 4 drives its second end to move, its first end will move toward or away from the clamping groove 2.

[0034] like Figure 1 , Figure 2 As shown, it also includes a fixing plate 5, which is disposed on the reaction barrel 1, and the pressure rod 3 is rotatably disposed on the fixing plate 5.

[0035] Specifically, the fixing plate 5 is installed on the side wall of the reaction bucket 1, and the fixing plate 5 provides space for the installation and fixing of the pressure rod 3.

[0036] like Figure 1 , Figure 2 As shown, a rotating shaft 6 is provided between the pressure rod 3 and the fixed plate 5.

[0037] Specifically, the rotating shaft 6 is installed between the pressure rod 3 and the fixed plate 5. The rotating shaft 6 is installed near the middle of the pressure rod 3. Therefore, when its second end is subjected to force, it will rotate around the rotating shaft 6, thereby causing its first end to move towards or away from the clamping groove 2. When it moves away from the clamping groove 2, the operator can put the clamping groove 2 on the outside of the nut. When it moves towards the clamping groove 2, the pressure rod 3 will squeeze the edge of the nut located in the clamping groove 2, causing local plastic deformation of the nut edge, thus achieving a firm lock.

[0038] like Figure 1 , Figure 4 As shown, the driving component 4 includes:

[0039] The driving component 41 is fixedly connected to the reaction barrel 1, and the output end of the driving component 41 faces the second end of the pressure rod 3.

[0040] Specifically, the drive component 41 is fixedly installed on the reaction barrel 1 to provide power for locking the nut. Its output end can stably apply force to the second end of the pressure rod 3 to drive it to rotate, so that its first end moves to squeeze the edge of the nut.

[0041] like Figure 1 , Figure 4 As shown, the reaction bucket 1 has a drive hole, and the drive component 41 is detachably connected to the drive hole.

[0042] Specifically, the top of the reaction barrel 1 has a drive hole along its radial direction, which is used to install the drive component 41 and also facilitates the output end of the drive component 41 to contact the side of the pressure rod 3, thereby increasing the force-bearing area of ​​the pressure rod 3 and providing a stable power output for locking the nut.

[0043] The drive component 41 is detachably connected to the drive hole, which can be a threaded connection or a connection via a lead screw and a snap fastener.

[0044] Among them, the driving component 41 can be a hydraulic cylinder or an electric push rod.

[0045] like Figure 1 , Figure 4 As shown, the drive component 41 is provided with a flange 7, which is threadedly connected to the drive hole.

[0046] Specifically, a flange 7 is mounted on the drive component 41. The drive component 41 and the flange 7 can be connected by welding or screws. The flange 7 has external threads on its outer side and internal threads in its drive hole. The drive component 41 can be rotated and screwed into the drive hole through the flange 7. At the same time, the threaded connection between the drive component 41 and the drive hole also facilitates the disassembly of the drive component 41, making it convenient for inspection and replacement.

[0047] like Figure 1 , Figure 4 As shown, the driving component 41 is a hydraulic cylinder.

[0048] like Figure 1 , Figure 4 As shown, the driving component 4 further includes:

[0049] Hydraulic station 42, wherein a manual valve 43 is provided on hydraulic station 42;

[0050] Hydraulic pipe 44 is disposed between the hydraulic station 42 and the drive component 41.

[0051] Specifically, the drive assembly 4 also includes a hydraulic station 42, a manual valve 43, and a hydraulic pipe 44. The hydraulic station 42, as the power source for the entire drive assembly 4, has a stable and reliable hydraulic oil output capability. The manual valve 43, located on the hydraulic station 42, is a standard two-position three-way manual hydraulic valve and is a key component controlling the working state of the hydraulic system. When the manual valve 43 is in position A, the hydraulic station 42 is in an unloaded state. At this time, the hydraulic oil circulates within the system without generating pressure output, and the equipment is in a standby state, facilitating the operator's preparation work such as equipment positioning and adjustment. When the manual valve 43 is in position A, the hydraulic station 42 enters a pressurized state. Under the action of the oil pump, the hydraulic oil is output to the hydraulic pipe 44 at a set pressure, providing power for subsequent nut tightening operations. The operation of the manual valve 43 is simple and intuitive. The operator only needs to manually operate the valve stem to quickly switch the working state of the hydraulic station 42, realizing the start and stop control of the equipment.

[0052] like Figure 1 , Figure 4 As shown, it also includes a spherical pin 8, which is disposed at the second end of the pressure rod 3 on the side facing the drive member 41.

[0053] Specifically, the spherical pin 8 is located at the second end of the pressure rod 3 facing the drive member 41. Its unique spherical structure design enables multi-directional force transmission and buffering between the drive member 41 and the pressure rod 3. When the drive member 41 pushes the spherical pin 8 under the action of hydraulic oil, the curved surface of the spherical pin 8 can evenly distribute the driving force to the pressure rod 3, avoiding the pressure rod 3 from tilting or local stress concentration due to uneven force distribution, ensuring that the pressure rod 3 can rotate smoothly and accurately press the edge of the nut.

[0054] Meanwhile, the spherical structure of the spherical pin 8 has a certain elastic deformation capacity, which can effectively absorb the vibration and impact generated by the movement of the drive component 41 during equipment operation. When the hydraulic system pressure fluctuates instantaneously, the spherical pin 8 can buffer the impact force through its own elastic deformation, reduce the transmission of vibration to the pressure rod 3 and the entire equipment, reduce equipment operating noise, and extend the service life of components such as the pressure rod 3 and the rotating shaft 6.

[0055] like Figure 1 , Figure 4 As shown, the spherical pin 8 is threadedly connected to the pressure rod 3.

[0056] Specifically, the spherical pin 8 is threadedly connected to the pressure rod 3, which facilitates the disassembly of the spherical pin 8 and makes it easy to replace it during subsequent maintenance.

[0057] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
