[0027] Example 1

[0028] Reference Figure 1 , which is the first embodiment of the present invention, provides an indoor voltage transformer fuse auxiliary installation and disassembly insulation tool, which includes a clamping unit 100 and a support unit 200. The operator controls the movement of the entire tool through the operating component 102. The operating component 102 is connected to the propulsion component 103. When the operating component 102 rotates, it drives the propulsion component 103 to move. The movement of the propulsion component 103 directly acts on the claw clamp component 101, so that the claw clamp component 101 can be opened and closed, thereby clamping or releasing the high-voltage fuse. The auxiliary bracket component 201 is connected to the clamping unit 100 through the adjustment component 202. The adjustment component 202 allows the auxiliary bracket component 201 to adjust the angle and position relative to the clamping unit 100 to adapt to different working environments and operation requirements. The auxiliary bracket component 201 provides stable support for the entire tool, reduces shaking during operation, and improves the accuracy and safety of the operation.

[0029] Specifically, the gripping unit 100 includes a claw clamping assembly 101, an operating assembly 102 disposed on the top of the claw clamping assembly 101, and a propulsion assembly 103 disposed at one end of the claw clamping assembly 101;

[0030] The supporting unit 200 includes an auxiliary support assembly 201 connected to the clamping unit 100 , and an adjusting assembly 202 connected to the auxiliary support assembly 201 .

[0031] In summary, the modularization of functions and optimization of structure are achieved through the clamping unit and the support unit. The coordinated design of the claw clamp assembly, the operating assembly and the propulsion assembly in the clamping unit enables the tool to accurately control the clamping force and position, effectively preventing damage to the fuse. The coordination of the auxiliary bracket assembly and the adjustment assembly in the support unit provides stable support and flexible adjustment functions, allowing the tool to adapt to various complex working environments.

[0032] Example 2

[0033] Reference Figures 1 to 4, which is the second embodiment of the present invention, provides an indoor voltage transformer fuse auxiliary installation and disassembly insulation tool, which includes a clamping unit 100 and a support unit 200. The operator controls the movement of the entire tool through the operating component 102. The operating component 102 is connected to the propulsion component 103. When the operating component 102 rotates, it drives the propulsion component 103 to move. The movement of the propulsion component 103 directly acts on the claw clamp component 101, so that the claw clamp component 101 can be opened and closed, thereby clamping or releasing the high-voltage fuse. The auxiliary bracket component 201 is connected to the clamping unit 100 through the adjustment component 202. The adjustment component 202 allows the auxiliary bracket component 201 to adjust the angle and position relative to the clamping unit 100 to adapt to different working environments and operation requirements. The auxiliary bracket component 201 provides stable support for the entire tool, reduces shaking during operation, and improves the accuracy and safety of the operation.

[0034] Specifically, the gripping unit 100 includes a claw clamping assembly 101, an operating assembly 102 disposed on the top of the claw clamping assembly 101, and a propulsion assembly 103 disposed at one end of the claw clamping assembly 101;

[0035] The supporting unit 200 includes an auxiliary support assembly 201 connected to the clamping unit 100 , and an adjusting assembly 202 connected to the auxiliary support assembly 201 .

[0036] Furthermore, the operating assembly 102 includes an operating rod 102a, an insulating handle 102b disposed at the lower end of the operating rod 102a, and a universal joint 102c disposed at the upper end of the operating rod 102a.

[0037] Furthermore, the propulsion assembly 103 includes a screw rod 103a and a propulsion block 103b disposed at the upper end of the screw rod 103a. The lower end of the screw rod 103a is sleeved and fixed to the universal joint 102c, and the upper end of the screw rod 103a is connected to the propulsion block 103b through a thread.

[0038] Furthermore, the claw clamp assembly 101 includes a claw clamp 101a designed as an X structure, the claw clamp 101a is connected to the push block 103b, and the movement of the push block 103b can change the gripping range of the claw clamp 101a.

[0039] Furthermore, soft pads 101b are provided inside the two groups of clamping openings at the upper end of the claw clamp 101a.

[0040] Furthermore, the auxiliary bracket assembly 201 includes an auxiliary bracket 201a, a support rod 201b connected to one end of the auxiliary bracket 201a, a collar 201c sleeved on the other end of the support rod 201b, and a pressing piece 201d fixedly connected to the collar 201c;

[0041] The adjustment component 202 includes a connecting column 202a tightly fitted with the pressing plate 201d, a protrusion arranged in the middle of the outer periphery of the connecting column 202a, and a bearing 202b sleeved on the protrusion.

[0042] Preferably, one end of the support rod 201b is connected to the ring 201c through a second butterfly screw 203b. When the auxiliary bracket needs to be adjusted in angle, the second butterfly screw 203b can be turned to adjust the tightness of the connection. After determining the angle, the second butterfly screw 203b is tightened to fix the support rod 201b to avoid shaking during the operation of the auxiliary clamping part. The other end of the support rod 201b is connected to the auxiliary bracket 201a through the first butterfly screw 203a, which has the same function as the second butterfly screw 203b. The auxiliary bracket 201a can be fixed and the direction of the auxiliary bracket 201a can be adjusted through the first butterfly screw 203a.

[0043] Furthermore, a circle of protrusions is provided in the middle of the outer periphery of the connecting column 202a, a bearing 202b is provided above the protrusions, and a pressing plate 201d is provided below the protrusions. The connecting column 202a is tightly sleeved on the universal joint 102c and connected to the outer periphery of one end of the screw rod 103a.

[0044] Preferably, there is a circle of protrusions in the middle of the outer periphery of the connecting column 202a, and the bearing 202b is sleeved on the top of the protrusion. The outer diameter of the connecting column 202a matches the inner diameter of the bearing 202b. When the connecting column 202a rotates, the inner ring of the bearing 202b rotates accordingly, but the outer ring does not rotate together. The pressing plate 201d is sleeved under the protrusion. The outer diameter of the connecting column 202a matches the inner diameter of the pressing plate 201d exactly, and they can fit together, but when the connecting column 202a rotates, the pressing plate 201d does not rotate together. The connecting column 202a is tightly sleeved on the outer periphery of one end of the universal joint 102c connected to the screw rod 103a, and is tightly connected to the universal joint 102c. When the universal joint 102c rotates, it will rotate together.

[0045] Furthermore, the bearing 202b is sleeved and fixed with the collar 201c, the collar 201c is connected and fixed with the pressing plate 201d by screws, and the outer diameter of the connecting column 202a is consistent with the inner diameter of the pressing plate 201d.

[0046] Preferably, the bearing 202b is sleeved and fixed together with the ring 201c, the outer diameter shape and size of the ring 201c is consistent with the pressing plate 201d, and the ring 201c is connected and fixed together with the pressing plate 201d by a screw. Under the joint action of the protrusion of the connecting column 202a and the pressing plate 201d, it is ensured that the auxiliary bracket part will not slide up and down during operation and the bracket part will not rotate when the operating lever is rotated, thereby avoiding accidents and providing safety and stability.

[0047] Furthermore, one end of the support rod 201b is connected to the auxiliary bracket 201a through a first butterfly screw 203a, and the other end is connected to the collar 201c through a second butterfly screw 203b.

[0048] There are three first butterfly screws 203a installed on the tool, one of which is installed at the connection between the auxiliary bracket 201a and the support rod 201b, and two are installed at the connection of the claw clamp 101a itself. The three first butterfly screws 203a have the same function: to connect and fix, to improve the stability of the tool; to adjust the direction of clamping, so that the tool can adapt to the fuses that need to be replaced and removed in different directions.

[0049] Furthermore, the universal joint 102c is fixedly connected by a third butterfly screw 203c, and the third butterfly screw 203c is used to fix the two pieces of the universal joint 102c.

[0050] It should be noted that the lower end of the operating rod 102a is sleeved with an insulating handle 102b, which is convenient for operators to hold and operate, and improves safety. The upper end is sleeved and fixed with the universal joint 102c, and when the operator turns the handle, the universal joint 102c can be driven to rotate together. The angle adjustment of the entire tool is controlled by the universal joint 102c. After the universal joint 102c is adjusted to determine the angle, the two pieces of the universal joint 102c are fixedly connected by the third butterfly screw 203c to avoid shaking during the operation of the operator and cause accidents. One end of the universal joint 102c is sleeved and fixed with the operating rod 102a, and the other end is sleeved and fixed with the lower end of the screw rod 103a. When the operator turns the handle, the universal joint 102c is driven to rotate through the operating rod 102a, and the screw rod 103a will also rotate accordingly. The upper end of the screw rod 103a is connected to the propulsion block 103b through a thread. When the screw rod 103a rotates forward, the propulsion block 103b is pushed forward. The claw clamp 101a is designed as an X structure. When the propulsion block 103b moves forward, the distance between the two gripping clamps at the lower end of the X structure increases, and the two gripping clamps at the upper end are The spacing between the openings is reduced, and the grasping range of the entire claw clamp 101a is reduced, thereby achieving the purpose of tightly grasping the fuse. Similarly, when the screw rod 103a rotates in the opposite direction, it drives the push block 103b to retreat. When the push block 103b retreats, the spacing between the two grasping clamps at the lower end of the X structure is reduced under the action of the torsion spring, and the spacing between the two clamping openings at the upper end is increased. The grasping range of the entire claw clamp 101a is increased, which is convenient for operators to take out the fuse to be replaced. The inner sides of the two clamping openings at the upper end of the claw clamp 101a are affixed with soft pads 101b to avoid damage to the porcelain layer around the fuse during operation.

[0051] When using, adjust the angle and position of the tool. First, rotate and loosen the third butterfly screw 203c, adjust the angle of the universal joint 102c, so that the tool can adapt to the working environment, and then adjust the meshing angle of the universal joint 102c. After the adjustment is completed, re-tighten the third butterfly screw 203c to fix the universal joint 102c. Then, rotate and loosen the second butterfly screw 203b to adjust the angle position of the support rod 201b. Since one end of the support rod 201b is movably and adjustably connected to one end of the support rod 201b through the second butterfly screw 203b, the angle position of the support rod 201b can be adjusted by loosening the second butterfly screw 203b. Finally, rotate and loosen the first butterfly screw 203a. Since the first butterfly screw 203a is movably and adjustably connected to the auxiliary bracket 201a, the first butterfly screw 203a is loosened by rotating and adjusting it, and the position of the auxiliary bracket 201a is adjusted. After the adjustment is completed, tighten all butterfly screws.

[0052] The operator holds the insulating handle 102b and brings the tool close to the fuse to be replaced. By rotating the operating rod 102a, the upper end of the operating rod 102a is connected to the universal joint 102c. When the operating rod 102a rotates, the universal joint 102c rotates accordingly, driving the universal joint 102c and the screw rod 103a to rotate. The screw rod 103a is connected to the push block 103b by a thread, so the rotation of the screw rod 103a causes the push block 103b to move along the axial direction of the screw rod. The rotation of the screw rod 103a drives the push block 103b to move axially. When the screw rod 103a rotates forward, the push block 103b moves forward, so that the distance between the two clamps at the upper end of the X-structure claw clamp 101a decreases, and the distance between the two clamps at the lower end increases, ready to clamp the fuse. When the screw rod 103a rotates in the opposite direction, the push block 103b moves back, the distance between the two lower jaws decreases, and the distance between the two upper jaws increases, so that the claw clamp 101a is loosened and ready to release the fuse. The push block 103b moves forward to the appropriate position, and the upper two jaws of the X-structure claw clamp 101a clamp the fuse. The soft pad 101b inside the claw clamp 101a protects the fuse from being damaged. After the replacement is completed, the reverse operation causes the push block 103b to move back, the claw clamp 101a is loosened, and the new fuse is released.

[0053] During operation, if the working angle needs to be adjusted, the gripping unit 100 can be rotated relative to the supporting unit 200 by the cooperation of the bearing 202b and the connecting column 202a to adapt to different working positions. Repeat the above steps until the removal and installation of the fuse are completed. During the whole process, the auxiliary bracket assembly 201 provides stable support to ensure the accuracy and safety of the operation.

[0054] In summary, the present invention allows the replacement of high-voltage fuses without power outages through the combination of a clamping unit and a supporting unit, which significantly shortens the operation time and improves safety. The design of the insulating handle and the universal joint not only ensures operational safety, but also enhances the flexibility of the tool. The precisely controlled claw clamping mechanism, combined with the X-structure design and soft pad protection, can adapt to fuses of different sizes and reduce the risk of equipment damage. The multi-angle adjustment function of the auxiliary bracket and the adjustment assembly enables the tool to adapt to various narrow spaces. The innovative design of the connection structure improves the stability and flexibility of the tool, while the quick-disassembly butterfly screw connection method enhances the adaptability and ease of operation of the tool.
