Technical Field

[0001] This utility model relates to the field of circuit breaker hoisting technology, specifically to a simple hoisting tool for circuit breakers. Background Technology

[0002] A 35kV circuit breaker is a high-voltage circuit breaker used in power systems. It is specifically designed for use in power equipment and distribution networks with a rated voltage of 35 kV to protect power lines and related equipment from overloads, short circuits and other electrical faults.

[0003] In the existing technology, when circuit breakers are disassembled and installed, due to their large weight and the certain height of their installation position, hoisting is often required. However, cranes are expensive. If hoisting is not used, relying on manual labor will greatly increase the time required for disassembling and installing circuit breakers, resulting in low work efficiency.

[0004] Therefore, it is necessary to invent a simple hoisting tool for circuit breakers. Utility Model Content

[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] Please refer to the appendix. Figures 1-4 The simple hoisting tool for circuit breakers provided by this utility model includes a base 1, a lower support column 2 vertically fixed on one side of the top of the base 1, an upper support column 3 installed on the top of the lower support column 2 through a rotating component, a boom 4 horizontally fixed on the top of the upper support column 3, a fixing component adjustablely installed on the base 1, a reinforcing component fixed between the base 1 and the lower support column 2 and between the upper support column 3 and the boom 4, and a hoisting component detachably installed at the bottom of the boom 4.

[0025] The fixing assembly includes a clamping plate 5, which is located directly below the base 1. Each of the four corners of the base 1 has a first through hole 6 vertically, and each of the four corners of the clamping plate 5 has a second through hole 7 vertically. A threaded rod 8 vertically passes through both the first and second through holes 6. Locking nuts 9 are threadedly connected to both the upper and lower ends of the threaded rod 8. The bottom of the locking nut 9 at the upper end of the threaded rod 8 abuts against the top of the base 1, and the top of the locking nut 9 at the lower end of the threaded rod 8 abuts against the bottom of the clamping plate 5. Nylon anti-loosening nuts 10 are also threadedly connected to both the upper and lower ends of the threaded rod 8. The end of the anti-loosening nut 10 abuts against the end of the locking nut 9. Specifically, the operator can place the clamp 5 under the frame (not shown in the figure), then place the base 1 on top of the frame, and pass the threaded rod 8 through the base 1 and clamp 5. Then, by rotating the locking nut 9, the clamp 5 and the base 1 are fixed, thereby realizing the function of fixing the lifting tool on the frame. It can be fixed on frames of different thicknesses. Under the action of the nylon anti-loosening nut 10, the locking nut 9 is effectively prevented from loosening, thus ensuring the stability of the lifting tool.

[0026] The rotating assembly includes an annular base plate 11, the bottom of which is fixed to the top of the lower support column 2. A turntable bearing 12 is fixed to the top of the annular base plate 11. An upper cover plate 13 is fixed to the bottom of the upper support column 3. The bottom of the upper cover plate 13 is fixed to the top of the turntable bearing 12. An inner sleeve 14 is vertically fixed to the center of the bottom of the upper cover plate 13. A slot 15 is opened at the center of the top of the lower support column 2. An outer ring 16 is fixed to the inner wall of the slot 15. The inner sleeve 14 is inserted into the slot 15. The surface of the inner sleeve 14 is in contact with the inner surface of the outer ring 16. Specifically, under the action of the turntable bearing 12, the lower support column 2 and the upper support column 3 have a rotation function, so that the lifting tool has a rotation lifting function. Under the insertion and limiting action of the inner sleeve 14, the slot 15, and the outer ring 16, the stability of the upper support column 3 during rotation can be effectively improved.

[0027] A rotating handle 17 is fixed to the surface of the upper support column 3. Several reinforcing plates 18 are fixed in a circular array at the bottom of the annular base plate 11. The surfaces of the reinforcing plates 18 are all fixed to the surface of the lower support column 2. Operators can manually rotate the upper support column 3 through the rotating handle 17. Under the reinforcement of the reinforcing plates 18, the firmness between the annular base plate 11 and the lower support column 2 is effectively improved.

[0028] The reinforcing components include a first reinforcing rod 19 and a second reinforcing rod 20. The bottom end of the first reinforcing rod 19 is fixed to the top of the base 1, and the top end of the first reinforcing rod 19 is inclinedly fixed to the surface of the lower support column 2. The bottom end of the second reinforcing rod 20 is fixed to the surface of the upper support column 3, and the top end of the second reinforcing rod 20 is inclinedly fixed to the bottom of the boom 4. Specifically, the reinforcement effect of the first reinforcing rod 19 can effectively improve the stability of the lower support column 2, and the reinforcement effect of the second reinforcing rod 20 can effectively improve the stability of the boom 4.

[0029] The lifting assembly includes several lifting rings 21, the tops of which are evenly fixed to the bottom of the boom 4. The assembly also includes a hand chain hoist 22. It should be noted that the hand chain hoist 22 is preferably an HS-C type hand chain hoist with a lifting height of 3m, a rated load of 1t, a minimum hook spacing of 306mm, and a net weight of 9kg. These are widely available on the market. A first hook 23 is fixed to the top of the hand chain hoist 22, and this hook 23 is suspended from any of the lifting rings 21. The bottom end of the lifting chain of the hand chain hoist 22 is fixed with a device for lifting broken parts. Specifically, the second hook 24 of the circuit breaker allows the operator to install the manual hoist 22 on the boom 4 via the first hook 23, and then lift the circuit breaker using the second lifting ring 24. The operator can then manually pull the lifting chain to lift the circuit breaker, thus effectively lifting the circuit breaker and facilitating its easy installation and removal. This significantly shortens the operation time and improves efficiency. Furthermore, the lifting tool has a simple overall structure, is easy to install and remove, greatly reducing the tool's setup and recovery time. It can also be reused, effectively reducing costs.

[0030] The usage process of this utility model is as follows: The operator first places the clamp plate 5 under the structure, then places the base 1 on top of the structure, and passes the threaded rod 8 through the base 1 and clamp plate 5. Then, the clamp plate 5 and base 1 are fixed by rotating the locking nut 9 and the nylon anti-loosening nut 10. The hoisting tool is fixedly installed on the structure. Then, the manual hoist 22 is installed on the boom 4 by the first hook 23. Then, the circuit breaker is hoisted by the second lifting ring 24, and the lifting chain is manually pulled to realize the hoisting operation of the circuit breaker. The upper support column 3 can be manually rotated by the handle 17, so that the hoisting tool has a rotation hoisting function.

[0031] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art can modify this utility model or modify it into an equivalent technical solution using the technical solution described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solution of this utility model are within the scope of protection claimed by this utility model.
