Description

Technical Field

[0001] This utility model relates to the field of gas-insulated switchgear circuit breaker manufacturing, specifically to a circuit breaker installation fixture. Background Technology

[0002] Gas-insulated circuit breakers play a crucial role in the control and protection of power systems. Their assembly quality and installation efficiency directly affect the overall performance and operational reliability of the unit. Currently, during circuit breaker installation, due to the complex structure and large size of the circuit breaker, high precision and stability are required. Traditional manual operation, typically using hoisting methods, is not only inefficient and labor-intensive but also poses certain safety hazards. Especially in the assembly of the circuit breaker mechanism and terminals, connection to the gas box, and transportation, significant manpower is often required, making the operation difficult and highly dependent on the skill level of the installers, hindering the achievement of standardized and efficient assembly processes.

[0003] Due to the different circuit breaker models and their varying assembly orientations with the gas-insulated switchgear, existing assembly platforms and tools are insufficient to meet the installation requirements of multi-angle and multi-directional adjustments of the circuit breakers, making it difficult to achieve standardization, efficiency, and safety in the assembly process. Furthermore, the assembly of the circuit breaker mechanism with the poles and the installation of the circuit breaker on the gas box often require two auxiliary devices, making the operation cumbersome and complex.

[0004] Therefore, there is an urgent need to design an installation auxiliary device that is structurally sound, easy to operate, and safe and reliable. Through an adjustable synchronous lifting structure and an adjustable flipping structure, the circuit breaker can be accurately positioned and fixed during the assembly process, thereby improving the safety, flexibility and efficiency of the assembly process and providing a systematic and standardized solution for the installation of circuit breakers. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the purpose of this utility model is to provide a circuit breaker installation fixture.

[0006] To achieve the purpose of this utility model, the technical solution adopted is as follows: A circuit breaker installation fixture, comprising: A bracket, on which at least one pair of lead screws are provided; The lower end of the lead screw is supported and fixed to the bracket by a limiting block; A fixed gearbox is provided above the lead screw, and the two fixed gearboxes above a pair of lead screws are connected by a transmission rod. The lead screw is equipped with a lifting gearbox, which drives the lifting transmission of the lead screw. A mounting platform is provided between the lifting gearboxes via a support rod. A circuit breaker is installed on the mounting platform, and the mounting platform is fixed to the bottom of the circuit breaker. The lifting transmission of the lifting gearbox is controlled by shaking the lifting handle at the top of the lead screw.

[0007] The tilting of the lifting gearbox is controlled by a tilting handle in conjunction with a tilting connector.

[0008] In a preferred embodiment of this utility model, the mounting platform has two mounting holes on each side for connecting to the support rod, and three rows of mounting holes in the middle for fixing the circuit breaker. The mounting platform is connected to the bottom of the circuit breaker mechanism's housing. By fixing the mounting platform to the bottom of the circuit breaker, subsequent assembly of the auxiliary circuit breaker with the gas box does not require secondary disassembly; it can be directly rotated to a suitable angle for installation.

[0009] In a preferred embodiment of this utility model, the lifting gearbox is threadedly engaged with the lead screw, and can be raised and lowered as the lead screw rotates; The lifting gearbox has a worm gear inside that is connected to the flip handle. The flip connector is connected to the helical gear inside it. When the flip handle is turned, the mounting platform can be flipped. The flip angle can be precisely controlled and is not affected by the center of gravity of the circuit breaker, making it safe and efficient.

[0010] In a preferred embodiment of this utility model, the limiting block is installed on the bracket to fix the position of the lead screw and ensure that it can rotate normally while preventing the lifting gearbox from falling off the lead screw.

[0011] In a preferred embodiment of this utility model, the base plate of the bracket is provided with casters.

[0012] The beneficial effects of this utility model are as follows: This utility model provides an efficient, safe, and flexible auxiliary solution for the installation process of gas-insulated switchgear circuit breakers, and has significant technical advantages and application value.

[0013] By employing an adjustable synchronous lifting structure and an adjustable tilting structure, this device effectively solves the problems of high manual labor intensity, low assembly accuracy, high safety risks, and low efficiency in traditional installation methods. It achieves standardized, efficient, and safe operation in key stages such as circuit breaker and pole assembly, circuit breaker and gas box connection, and circuit breaker transportation. Compared to existing technologies, the beneficial effects of this device are mainly reflected in the following aspects: First, it significantly improves installation efficiency. Through its structured design, the device can quickly locate and fix the circuit breaker, reducing manual intervention and shortening the assembly cycle. Second, it enhances operational safety. The device has excellent support and protection functions, avoiding potential injury to equipment and personnel during installation. Third, it enhances operational flexibility and adaptability. Through the adjustment of the synchronous lifting and tilting functions, the device can be adapted to different models and structures of circuit breaker products, meeting installation needs in multiple scenarios and possessing good versatility and expandability.

[0019] like Figure 1As shown in Figure 2, a circuit breaker installation fixture includes a bracket 3, on which at least one pair of lead screws 4 are mounted. The lower end of the lead screw 4 is supported and fixed to the bracket 3 by a limiting block 1.

[0020] The limiting block 1 is installed on the bracket 3 to fix the position of the lead screw 4 and ensure that it can rotate normally while preventing the lifting gearbox 10 from falling off the lead screw 4.

[0021] A fixed gearbox 7 is installed above the lead screw 4, and the two fixed gearboxes 7 above a pair of lead screws 4 are connected by a transmission rod 8.

[0022] The lead screw 4 is equipped with a lifting gear box 7, which drives the lifting gear box 7 to lift and lower.

[0023] A mounting platform 5 is provided between the lifting gearboxes 7 via a support rod 9. A circuit breaker 14 is installed on the mounting platform 5, and the mounting platform 5 is fixed to the bottom of the circuit breaker 14.

[0024] Specifically, mounting platform 5 has two mounting holes on each side for connecting to support rod 9, and three rows of mounting holes in the middle for fixing circuit breaker 14. Mounting platform 5 is connected to the bottom of the chassis of circuit breaker 14. After fixing mounting platform 5 to the bottom of circuit breaker 14, when assembling auxiliary circuit breaker 14 with gas box 13, there is no need for secondary disassembly; it can be directly flipped to a suitable angle for installation.

[0025] The lifting transmission of the lifting gearbox 10 is controlled by shaking the lifting handle 6 at the top of the lead screw 4, and the flipping of the lifting gearbox 10 is controlled by the flipping handle 11 in conjunction with the flipping connector 12.

[0026] The lifting gearbox 10 is threadedly engaged with the lead screw 4, allowing it to rise and fall with the rotation of the lead screw 4. Inside the lifting gearbox 10 is a worm gear connected to the flip handle 11, and a flip connector 12 connected to its internal helical gear. By cranking the flip handle 11, the mounting platform 5 can be flipped, allowing precise control of the flip angle. This is unaffected by the circuit breaker's center of gravity, ensuring safety and efficiency. The base plate of the bracket 3 is equipped with casters.

[0027] When assembling the circuit breaker, first crank the flip handle 11 and the lifting handle 6 to adjust the mounting platform 5 to a suitable angle and height, install the circuit breaker mechanism 14 on the mounting platform 5, and then assemble the pole and mechanism.

[0028] If the gas box 13 is placed vertically when the circuit breaker 14 is installed, then... Figure 2 In the indicated state, crank the lifting handle 6 to adjust the circuit breaker 14 to a suitable height, and then push the bracket 3 to the appropriate position. After securing the circuit breaker mounting plate to the square steel at the gas box mounting hole, remove the screws connecting the bottom of the circuit breaker 14 to the mounting platform 5, remove the device, and the installation is complete.

[0029] If circuit breaker 14 is installed, gas box 13 is in a state of... Figure 3 As shown, after the circuit breaker 14 is assembled, you can crank the flip handle 11 to adjust the circuit breaker 14 to a suitable angle, and then turn the lifting handle 6 to lower the circuit breaker 14.

[0030] After securing the circuit breaker mounting plate to the square steel at the gas box mounting hole, remove the screws connecting the bottom of the circuit breaker 14 to the mounting platform 5, remove the device, and the installation is complete. The above shows and describes the basic principles, main features, and advantages of this utility model.
