Among them, there are at least two telescopic members 200. One end of each telescopic member 200 is connected to the hoisting body 100, and a connecting member 300 is connected to the other end of each telescopic member 200. The connecting member 300 is used to connect with the single - pole circuit breaker.

[0025] For the circuit breaker replacement tooling 10 in the above - mentioned embodiment, during use, the hoisting body 100 is installed on a crane. After all the connecting members 300 are connected to the arc - extinguishing chamber of the single - pole circuit breaker, then adjust the telescopic length of each telescopic member 200 to ensure that when the crane hoists the single - pole circuit breaker through the circuit breaker replacement tooling 10, the arc - extinguishing chamber of the single - pole circuit breaker is in a horizontal state as a whole. Furthermore, ensure that the forces on each telescopic member 200 and each connecting member 300 are balanced, avoid the telescopic member 200 or the connecting member 300 from breaking due to uneven force, and effectively improve the safety performance of the circuit breaker replacement tooling 10. In addition, in this application, by adjusting the telescopic length of the telescopic member 200, ensure that the arc - extinguishing chamber of the single - pole circuit breaker remains horizontal as a whole after being hoisted, avoid the situation of the arc - extinguishing chamber tipping over, reduce the swing amplitude of the single - pole circuit breaker during movement, and further reduce the probability of the arc - extinguishing chamber of the single - pole circuit breaker being knocked and the damage rate of the single - pole circuit breaker, improving the reliability of the circuit breaker replacement tooling 10; by ensuring that the arc - extinguishing chamber of the single - pole circuit breaker remains horizontal as a whole after being hoisted, enable the arc - extinguishing chamber of the single - pole circuit breaker to be accurately docked with the circuit breaker pole column, avoid the displacement of the lifting rod guide ring in the circuit breaker pole column during docking, and prevent the air leakage phenomenon caused by the displacement of the two sealing rubber rings above and below the guide ring. At the same time, in this application, through the connection of a plurality of connecting members 300 with the arc - extinguishing chamber of the single - pole circuit breaker, the requirements for the bundling skills and experience of the operating workers by the circuit breaker replacement tooling 10 are reduced, and the connection strength between the circuit breaker replacement tooling 10 and the arc - extinguishing chamber of the single - pole circuit breaker is increased, improving the reliability and safety of the circuit breaker replacement tooling 10.

[0026] Specifically, lifting rings corresponding to the connecting members 300 one - to - one are arranged on the arc - extinguishing chamber of the single - pole circuit breaker. During use, the hoisting body 100 is installed on a crane, and all the connecting members 300 are connected to the plurality of lifting rings on the arc - extinguishing chamber of the single - pole circuit breaker one - to - one.

[0027] Among them, the hoisting body 100 can be a hoisting bracket, a hoisting ring, a hoisting plate or other hoisting structures. The telescopic member 200 can be a telescopic rod, a telescopic cylinder or other telescopic structures. The connecting member 300 can be a connecting buckle, a connecting hook, a connecting rope or other connecting structures. The numbers of the telescopic member 200 and the connecting member 300 can both be flexibly adjusted according to actual usage needs. For example, the numbers of the telescopic member 200 and the connecting member 300 can both be two, three, four, etc. The other ends of the respective telescopic members 200 are all connected with the connecting members 300, and can be connected by means of buckling, hooking, screwing, sleeving flexible connection, rotational connection or other connection methods.

[0028] As Figure 1 shown, further, the circuit breaker replacement tooling 10 further includes a plurality of suspension straps 400. The number of the suspension straps 400 is the same as that of the telescopic members 200. One end of each suspension strap 400 is connected to the hoisting body 100, and the other end of each suspension strap 400 is correspondingly connected to the end of each telescopic member 200 far from the connecting member 300. Thus, when the circuit breaker replacement tooling 10 is in use, the hoisting body 100 is installed on the crane, and after all the connecting members 300 are connected to the arc extinguishing chamber of the single-pole circuit breaker, the telescopic lengths of the telescopic members 200 on each suspension strap 400 are adjusted. When each suspension strap 400 makes the arc extinguishing chamber of the single-pole circuit breaker in a horizontal state after being lifted, the force balance of each suspension strap 400 is ensured, avoiding the breakage of the suspension strap 400 due to uneven force, and effectively improving the safety performance of the circuit breaker replacement tooling 10. In addition, each telescopic member 200 is connected to the hoisting body 100 through each suspension strap 400, so that the positions of each telescopic member 200 and each connecting member 300 relative to the hoisting body 100 are adjustable. While facilitating the transportation and storage of the circuit breaker replacement tooling 10, the circuit breaker replacement tooling 10 can also be connected to single-pole circuit breakers of different specifications for hoisting, improving the practicability of the circuit breaker replacement tooling 10.

[0029] Optionally, the telescopic member 200 includes a locking screw buckle. One end of the locking screw buckle is connected to the end of the suspension strap 400 far from the hoisting body 100, and the other end of the locking screw buckle is connected to the connecting member 300. Thus, by controlling the rotation direction of the locking screw buckle, the length of the locking screw buckle is adjustable, improving the convenience of the circuit breaker replacement tooling 10.

[0030] Specifically, the sling buckle includes a frame, a first bolt, and a second bolt. First threaded holes and second threaded holes are respectively provided at both ends of the frame. The first bolt is installed in the first threaded hole. One end of the first bolt is connected to the end of the sling 400 away from the lifting body 100. The other end of the first bolt extends into the frame, and a plurality of first limiting protrusions are sequentially arranged along the circumferential direction at the end of the first bolt away from the sling 400. The second bolt is installed in the second threaded hole. One end of the second bolt is connected to the connecting member 300. The other end of the second bolt extends into the frame, and a plurality of second limiting protrusions are sequentially arranged along the circumferential direction at the end of the second bolt away from the connecting member 300.

[0031] During use, the length of the sling buckle can be adjusted by screwing the first bolt and / or the second bolt. By providing a plurality of first limiting protrusions, the first bolt is prevented from disengaging from the frame. By providing a plurality of second limiting protrusions, the second bolt is prevented from disengaging from the frame.

[0032] Optionally, a first eyelet is provided at the end of the sling 400 away from the telescopic member 200. The lifting body 100 is provided as a hanging ring, and the hanging ring is inserted through the first eyelet. In this way, the sling 400 can be stably and reliably installed on the hanging ring, ensuring that the sling 400 will not fall off the hanging ring, and improving the reliability of the circuit breaker replacement tooling 10. In addition, the sling 400 can move relative to the hanging ring, avoiding entanglement or torsion of the sling 400 during the lifting of the single-pole circuit breaker, and improving the safety of the circuit breaker replacement tooling 10. Specifically in this embodiment, four slings 400 are provided, and the four slings 400 are arranged at intervals along the circumferential direction of the hanging ring.

[0033] In other embodiments, a second eyelet is provided at the end of the sling 400 away from the lifting body 100, and the end of the sling buckle away from the hook is inserted through the second eyelet. In this way, it is ensured that the sling will not separate from the sling buckle, and the reliability of the circuit breaker replacement tooling 10 is improved.

[0034] As Figure 1 shown, in one embodiment, the connecting member 300 is provided as a hook 310. The circuit breaker replacement tooling 10 further includes a weight detection element, and the weight detection element is provided on the hook 310 and is used to detect the weight of the single-pole circuit breaker. In this way, during the process of the circuit breaker replacement tooling 10 lifting the single-pole circuit breaker, the operator can monitor the weight of the single-pole circuit breaker hung on the hook 310 in real time through the gravity detection element, so as to predict in advance the risk of the sling 400 breaking, and improve the safety of the circuit breaker replacement tooling 10.

[0035] Among them, the weight detection element can be a weight sensor, a pressure sensor or other detection elements. Specifically in this embodiment, at least one weight sensor is provided on each hook 310.

[0036] Optionally, the circuit breaker replacement tooling 10 further includes a warning component, and the warning component is communicatively connected to the weight detection element. In this way, when the weight of the single-pole circuit breaker hung on the hook 310 is greater than the preset weight value, the weight detection element is triggered and feeds back a trigger signal to the warning component, enabling the warning component to give a warning to remind the operator, thereby improving the safety of the circuit breaker replacement tooling 10. Specifically in this embodiment, the circuit breaker replacement tooling 10 further includes a controller. The weight detection element is communicatively connected to the controller, and the controller is communicatively connected to the warning component.

[0037] Among them, the warning component can be an alarm, a warning light or other warning structures. The value range of the preset weight value can be flexibly adjusted according to actual usage needs. Specifically, the value range of the preset weight value is less than or equal to the maximum load-bearing weight of the hook 310. The controller can be a single-chip microcomputer, a programmable logic controller or other control structures. The communication connection between the weight detection element and the controller, and the communication connection between the controller and the warning component can all be achieved through data lines, wires, Bluetooth, wireless communication network technologies or other communication methods.

[0038] As Figure 1 shown, in one embodiment, the connecting member 300 is set as a hook 310 provided with a break portion 311. The circuit breaker replacement tooling 10 further includes a control member 500. The control member 500 is installed on the hook 310 and is used to close or open the break portion 311. In this way, when the hook 310 needs to be connected to the arc extinguishing chamber of the single-pole circuit breaker, the control member 500 is driven to open the break portion 311, so as to easily hang the hook 310 on the arc extinguishing chamber of the single-pole circuit breaker, without the need for high bundling skills and experience, and the operation is simple and convenient. After the hook 310 hangs the arc extinguishing chamber of the single-pole circuit breaker, the control member 500 resets to close the break portion 311, preventing the hook 310 from falling off the arc extinguishing chamber of the single-pole circuit breaker, thereby improving the reliability and safety of the circuit breaker replacement tooling 10.

[0039] Among them, the control member 500 can be an electromagnetic switch, a spring piece or other control structures. Specifically in this embodiment, the control member 500 is set as an electromagnetic switch, and the electromagnetic switch is communicatively connected to the controller. In this way, the convenience of the circuit breaker replacement tooling 10 is improved.

[0040] Furthermore, the outer wall of the hook 310 is provided with an anti-slip portion. In this way, the anti-slip portion can increase the friction of the hook 310, improving the anti-slip performance of the hook 310 and enhancing the reliability of the circuit breaker replacement tooling 10.

[0041] Among them, the anti-slip portion can be an anti-slip pattern, an anti-slip protrusion or other anti-slip structures.

[0042] Optionally, the outer wall of the hook 310 is provided with a first reinforcing rib. In this way, the first reinforcing rib can increase the strength of the hook 310, so that the load-bearing capacity of the hook 310 is increased, and the reliability of the circuit breaker replacement tooling 10 is improved.

[0043] Optionally, the outer wall of the hanging ring is provided with a second reinforcing rib. In this way, the second reinforcing rib can increase the strength of the hanging ring, so that the load-bearing capacity of the hanging ring is increased, and the reliability of the circuit breaker replacement tooling 10 is improved.

[0044] In one embodiment, the circuit breaker replacement tooling 10 further includes a position detection element, which is installed on the hoisting body 100 and is used to detect the position of the single-pole circuit breaker. In this way, the position of the single-pole circuit breaker is detected by the position detection element, so as to facilitate the operator to judge whether the arc extinguishing chamber of the single-pole circuit breaker is in a horizontal state, and the convenience of the circuit breaker replacement tooling 10 is improved. In addition, the position detection element can also detect the position between the single-pole circuit breaker and the environmental components around the single-pole circuit breaker, facilitating the operator to know the distance between the single-pole circuit breaker and the environmental components in real time, so that the probability of collision between the single-pole circuit breaker and the environmental components is reduced, and the damage rate of the single-pole circuit breaker during hoisting is also reduced, improving the reliability of the circuit breaker replacement tooling 10.

[0045] Among them, the position detection element can be a camera, a vision sensor, an infrared sensor or other position detection structures. The number of position detection elements can be flexibly adjusted according to actual use needs. For example, the number of position detection elements can be one, two, three, four, etc. Specifically in this embodiment, the position detection element is set as a camera, there are four cameras, and the four cameras are arranged at intervals along the circumferential direction of the hanging ring and are all communicatively connected to the controller.

[0046] Optionally, anti-corrosion layers are provided on the hoisting body 100, the telescopic member 200 and the connecting member 300. In this way, the anti-corrosion layers can play a protective role on the hoisting body 100, the telescopic member 200 and the connecting member 300, ensure the stability of the load-bearing capacity of the hoisting body 100, the telescopic member 200 and the connecting member 300, and avoid the occurrence of the situation that the hoisting body 100, the telescopic member 200 or the connecting member 300 breaks due to the decrease of the load-bearing capacity, improving the reliability and service life of the circuit breaker replacement tooling 10.

[0047] Among them, the anti-corrosion layer can be a protective rubber layer, a protective paint layer or other anti-corrosion structures.

[0048] Specifically in this embodiment, the circuit breaker replacement tooling 10 is used for replacing the arc extinguishing chamber of the Siemens circuit breaker. Thus, when the circuit breaker replacement tooling 10 is in use, the hanging ring is hung on the hook of the crane, and after all the hooks are connected to the arc extinguishing chamber of the Siemens circuit breaker, the telescopic length of the turnbuckle on each sling 400 is adjusted to ensure that when the crane hoists the arc extinguishing chamber of the Siemens circuit breaker through the circuit breaker replacement tooling 10, the arc extinguishing chamber of the Siemens circuit breaker is in a horizontal state as a whole, thereby ensuring that each sling 400 is evenly stressed and avoiding the sling 400 from breaking due to uneven stress, effectively improving the safety performance of the circuit breaker replacement tooling 10. Secondly, in this embodiment, by adjusting the telescopic length of the turnbuckle, it is ensured that the arc extinguishing chamber of the Siemens circuit breaker remains in a horizontal state as a whole after being hoisted, reducing the swinging amplitude when the arc extinguishing chamber of the Siemens circuit breaker moves, and thereby reducing the probability of the arc extinguishing chamber of the Siemens circuit breaker being knocked, improving the reliability of the circuit breaker replacement tooling 10. Then, in this embodiment, the circuit breaker replacement tooling 10 is connected to the arc extinguishing chamber of the Siemens circuit breaker through multiple hooks, reducing the requirements for the bundling skills and experience of the operator, and increasing the connection strength between the circuit breaker replacement tooling 10 and the arc extinguishing chamber of the Siemens circuit breaker, improving the reliability and safety of the circuit breaker replacement tooling 10. Next, each turnbuckle is connected to the hanging ring through each sling 400, making the positions of each turnbuckle and each hook adjustable relative to the hanging ring. While facilitating the transportation and storage of the circuit breaker replacement tooling 10, the circuit breaker replacement tooling 10 can also be connected to arc extinguishing chambers of different specifications of Siemens circuit breakers for hoisting, improving the practicability of the circuit breaker replacement tooling 10.
