Description

Technical Field

[0002] In substation hoisting operations, insulation posture adjustment mainly refers to ensuring that the hoisted electrical equipment, especially those with insulating components such as transformers, disconnectors, etc., maintain the correct posture during the hoisting process to ensure that the insulation performance of the equipment is not damaged.

[0003] However, the prior art has the following disadvantages when used: when performing substation hoisting operations, it is necessary to use straps to tie up the equipment, and then connect the straps to the hoisting equipment, and use the hoisting equipment to lift it. However, the straps may wear or break due to long-term use or overload, which poses a potential safety hazard. In addition, during the hoisting operation, the staff will use insulating rods to control the posture of the equipment to avoid tilting or rotation, but the existing insulating rods are relatively long, which is not convenient for placement, carrying and transportation. In addition, due to the long length of the insulating rods, the insulating rods will produce an arc when lifted, and when the insulating rods are carried and moved, the insulating rods will shake, and the insulating rods will break. Therefore, there is an urgent need for an insulation posture adjustment device for substation hoisting operations to solve the above problems. Summary of the invention

After the other ends of the limit hooks 707 are tilted, the insertion block 704 at one end of the tapered insulating rod 2 702 is inserted into the interior of the tapered insulating rod 1 701, and then the pressed end of the limit hook 707 is released. Under the elastic force of the elastic member 709, the pressed end of the limit hook 707 rises. The other end of the limiting hook 707 enters the limiting hole 2 703 of the conical insulating rod 1 701, and the end of the limiting hook 707 entering the limiting hole 2 703 enters the limiting hole 3 705 again, which is beneficial to enhance the stability between the conical insulating rod 1 701 and the conical insulating rod 2 702 after they are connected, and at the same time, it is convenient to disassemble and assemble the conical insulating rod 1 701 and the conical insulating rod 2 702, which is convenient for placement, carrying and transportation. In addition, due to the structural shape of the conical insulating rod 2 702 and the conical insulating rod 1 701, the staff can hold the end of the insulating hook 707 to the conical insulating rod 1 701. One end gradually becomes thinner, which is beneficial to reducing the overall weight compared to a straight rod of the same diameter, and the stress distribution is more uniform, which can improve the stability and durability of the structure.

[0058] Working principle: put the lifting ring 1 on the hook of the external lifting equipment, use the external lifting equipment to move the lifting ring 1, the fixed block 2, the T-shaped frame 201, the reinforcement rod 8, the connecting block 9, the T-shaped bar 10 and the two U-shaped frames 3 to the outside of the equipment to be lifted, and then the staff rotates the two control wheels 303 to drive the two limit rods 302 to rotate in the fixed block 301, and the limit rod 302 drives the limit hole 1 311 and the worm 2 304 to rotate when the limit rod 302 rotates. When the worm 2 304 rotates, it drives the worm wheel 2 305 and the internal threaded tube 306 to rotate. When the internal threaded tube 306 rotates in the moving block 308, it drives the one-way threaded rod 307 to move vertically. When the one-way threaded rod 307 moves, it drives the L-shaped frame 4 and the protective pad 5 to move in the Z axis. The two-way threaded rod 309 is driven to rotate when the staff rotates the control frame 2 310, and the two-way threaded rod 309 is driven to rotate. When the two-way threaded rod 309 rotates, the moving block 308 moves in the Y axis in the U-shaped frame 3. When the moving block 308 moves, the internal threaded tube 306, the worm gear 2 305 and the worm 2 304 are driven to move, so as to enhance the stability of the cooperation between the worm gear 2 305 and the worm 2 304. When the worm 2 304 moves, the inner wall of the limiting hole 1 311 slides on the outer surface of the limiting rod 302. When the moving block 308 moves, it drives the unidirectional threaded rod 307 and the L-shaped frame 4 to move, which is conducive to meeting the needs of different widths. When the lifting equipment is installed, the staff member rotates the control frame 207 to drive the worm 203 and the connecting rod 204 to rotate. When the worm 203 rotates in the fixed block 202, it drives the worm wheel 205 to rotate. When the worm wheel 205 rotates, it drives the bidirectional threaded rod 206 to rotate in the T-shaped frame 201. When the bidirectional threaded rod 206 rotates, it drives the U-shaped frame 3 and the T-shaped bar 10 to move. When the T-shaped bar 10 moves, its outer surface slides on the inner wall of the T-shaped groove 901, so as to enhance the stability of the U-shaped frame 3 when it moves on one side of the connecting block 9. When the U-shaped frame 3 moves, it drives the bidirectional threaded rod 2 309, the moving block 308, the unidirectional threaded rod 307, the L-shaped frame 4 and the protective pad 5 to move in the X-axis, so as to move the protective pad 5 to the position where the lifting is required. The U-shaped frame 3 is placed under the equipment, and then the outer surface of the U-shaped frame 3 is brought into contact with the outer surface of the equipment to be hoisted, and then the control wheel 303 is rotated to rotate, and the L-shaped frame 4 and the protection pad 5 are moved upward on the Z axis, so that the protection pad 5 is tightly attached to and deformed with the outer surface of the equipment to be hoisted, thereby enhancing the friction with the equipment to be hoisted, and enhancing the stability of clamping and fixing the equipment to be hoisted. Replacing soft materials such as straps with metal or other hard materials is conducive to reducing safety hazards. When in use, the fixed shaft 708 is rotatably installed on the inner wall of the fixed block four 706 to enhance the stability of the fixed shaft 708 and the limit hook 707. The staff presses the two limit hooks 707 at one end of the conical insulating rod two 702, and the limit hook 707 uses the fixed shaft 708 as the center point.The other ends of the two limit hooks 707 are tilted from the limit hole 3 705. After the other ends of the limit hooks 707 are tilted, the insertion block 704 at one end of the second conical insulating rod 702 is inserted into the interior of the first conical insulating rod 701, and then the pressed end of the limit hook 707 is released. Under the elastic force of the elastic member 709, the pressed end of the limit hook 707 rises, and the other end of the limit hook 707 enters the limit hole 2 703 of the first conical insulating rod 701, and the end of the limit hook 707 that enters the limit hole 2 703 enters the limit hole 3 705 again, which is beneficial to enhance the stability between the first conical insulating rod 701 and the second conical insulating rod 702 after they are connected, and at the same time facilitates the disassembly and assembly of the first conical insulating rod 701 and the second conical insulating rod 702. 02, convenient for placement, carrying and transportation, and due to the structural shape of the conical insulating rod 2 702 and the conical insulating rod 1 701, the end from the handheld end of the staff to the end of the insulating hook 7 gradually becomes thinner, which is conducive to reducing the overall weight compared to straight rods of equal diameter, and the stress distribution is more uniform, which can improve the stability and durability of the structure. The end of the conical insulating rod 2 702 away from the conical insulating rod 1 701 can still be connected to the conical insulating rod 2 702, thereby extending the length.
