Description

Technical Field

[0001] This invention relates to the field of circuit breaker tank closing equipment, and in particular to a circuit breaker tank closing and docking device. Background Technology

[0002] In the field of gas-insulated metal-enclosed switchgear technology, circuit breakers, as core control components, directly determine the overall operational stability and withstand voltage performance of the equipment through their assembly quality. Fast-acting circuit breakers typically consist of two parts: the circuit breaker housing and the closing resistor combination housing. Their final assembly in the factory is a critical step in the circuit breaker manufacturing process—it requires precise alignment and secure connection of the flanges connecting the two housings to ensure the insulation reliability of the equipment during operation and avoid problems such as withstand voltage test failures caused by assembly deviations. Therefore, clear requirements are placed on the precision and stability of the assembly equipment.

[0003] Currently, the industry primarily uses traditional crane lifting and assembly methods for the in-factory connection of circuit breaker tanks and closing resistor combination tanks: the crane lifts the two tanks to the approximate connection position, and then operators manually adjust the tank posture and relative position with the aid of auxiliary tools, gradually reducing the distance between the two flanges until the connection is completed. This method was used in the early assembly of simple circuit breakers, but as the requirements for connection accuracy (such as flange verticality, height difference, and left-right alignment error) of circuit breakers have continued to increase, the limitations of this operating mode have gradually become apparent.

[0004] However, traditional crane assembly methods have significant drawbacks and are no longer sufficient to meet the demands for efficient and high-precision assembly: First, poor stability – during crane hovering, the crane is easily affected by external disturbances (such as airflow in the workshop and deformation of the lifting rope), causing the tank to sway and making it impossible for the tank to maintain a stable posture. This not only increases the difficulty of docking but may also generate metal debris due to tank collisions. If this debris remains inside the tank, it will directly affect the subsequent withstand voltage pass rate of the circuit breaker. Second, low docking accuracy – manual adjustment makes it difficult to accurately control the relative position of the two tanks, especially in the left-right alignment and front-back alignment of the flanges. Quantitative adjustment is not possible, often resulting in flange misalignment, uneven gaps, and other problems, leading to docking failures or repeated adjustments. Third, low efficiency – repeated crane starts and stops and manual fine-tuning are required, making the entire docking process time-consuming and reliant on operator experience, making it difficult to ensure assembly consistency. The core of these problems lies in the lack of a stable support and precise drive structure specifically designed for docking two tanks, which is precisely the key pain point that urgently needs to be addressed by new assembly equipment. Summary of the Invention

[0005] To address the issue of poor stability in existing circuit breaker tank connection methods, this invention provides a circuit breaker tank connection device.

[0006] To solve the above problems, the technical solution adopted by the present invention is as follows: A circuit breaker tank docking device includes two sets of spaced-apart rails arranged in parallel. Each set of rails includes two guide rails. A base frame for mounting and fixing the circuit breaker tank is slidably mounted on both sets of rails. A base frame for mounting and fixing the closing resistor combination tank is also slidably mounted on both sets of rails. The length direction of the base frame and the base frame is perpendicular to the length direction of the guide rails. The base frame is connected to a translation drive mechanism. Two sliding seats are slidably mounted on each set of rails. One sliding seat is used to connect the base frame and the other sliding seat is used to connect the base frame. A guide assembly for pre-connecting the circuit breaker tank and the closing resistor combination tank is installed on the circuit breaker tank. This circuit breaker tank docking device uses two sets of parallel rails with double sliding seats and corresponding base frames to stably support and fix the circuit breaker tank and the closing resistor combination tank, respectively, replacing the traditional crane hoisting method and avoiding the generation of metal debris from tank shaking and collision. The design of the base frame being perpendicular to the guide rails, the power output of the translation drive mechanism, and the pre-positioning function of the guide components enable precise alignment of the two tanks, effectively solving the problems of difficult and insufficient precision in traditional docking, and greatly improving the efficiency and reliability of tank docking.

[0007] Preferably, support columns 1 are installed at the corners of the top surface of base frame 1; support columns 2 are installed at the corners of the top surface of base frame 2; and lifting mechanisms are installed on the top surfaces of support columns 1 and 2. The support columns 1 and 2 at the corners of the base frame provide stable corner support for the two tanks, preventing them from shifting or tipping over. The lifting mechanisms on the top surfaces allow for precise four-point height and verticality adjustment of the two tanks, solving the problem of insufficient precision in traditional manual adjustment. This lays a solid foundation for the subsequent precise docking of the two tanks, improving the quality and stability of the docking.

[0008] Preferably, the lifting mechanism is a screw jack; both support columns one and two have clearance grooves to accommodate the screw of the screw jack; the top of the screw of the screw jack is fitted with a support for connecting the circuit breaker tank and the closing resistor combination tank. The screw jack has high transmission precision and stable adjustment, and can accurately control the height and verticality of the two tanks during docking. The clearance grooves on the support columns can avoid interference with the screw movement, ensuring smooth lifting. The support at the top of the screw can firmly connect and fix the tank, preventing displacement during adjustment or docking, thus comprehensively ensuring the precision and reliability of the tank docking.

[0009] Preferably, the support includes a base plate; a vertical plate is fixed to the center of the top surface of the base plate; the upper part of the vertical plate has through holes for bolts to pass through to connect the circuit breaker tank and the closing resistor combination tank; reinforcing ribs are installed between the vertical plate and the base plate. The base plate provides a stable installation foundation for the support, the vertical plate achieves a firm connection between the tank and the tank through the through holes and bolts, and the reinforcing ribs effectively enhance the structural strength of the support and prevent deformation under stress. The three work together to ensure that the tank does not shift or loosen during height adjustment and docking, providing a solid support guarantee for the precise docking of the two tanks.

[0010] Preferably, the sliding base includes a mounting plate; each corner of the bottom surface of the mounting plate is equipped with a slider with locking function; the slider is slidably mounted on the guide rail; a linear slide rail is provided on the top surface of the mounting plate; the linear slide rail extends perpendicularly to the direction of the guide rail; and a translation drive mechanism is connected to one end of the base frame. The mounting plate provides a stable bearing foundation for each component. The slider with locking function slides smoothly along the guide rail and can be fixed in position. The linear slide rail with its top surface perpendicular to the guide rail, combined with the translation drive mechanism, enables precise adjustment of the base frame in multiple directions (front-back, left-right) while preventing displacement after adjustment. This ensures precise alignment of the two tanks and improves the accuracy and efficiency of tank docking.

[0011] Preferably, the linear guide rail includes two opposing guide rails; a slider with a locking function is slidably mounted on the guide rails; the slider connects the base frame and the base frame. The two opposing guide rails provide stable guidance for the slider, preventing sliding deviation. The slider with the locking function can smoothly adjust the position of the base frame and the base frame, and after adjustment, it can firmly lock to prevent displacement. At the same time, it accurately transmits sliding motion, helping the two tanks to achieve precise alignment in a specific direction, further ensuring the accuracy and stability of tank docking.

[0012] Preferably, the translation drive mechanism one and translation drive mechanism two have the same structure; translation drive mechanism one includes a vertical plate; side plates are vertically fixed on both sides of the vertical plate; a cylinder is mounted on the vertical plate; the piston rod end of the cylinder passes through the vertical plate and is fitted with a connector for connecting base frame two and base frame one. The identical structure of translation drive mechanism one and translation drive mechanism two simplifies manufacturing and maintenance processes and reduces costs; the vertical plate, together with the side plates, provides a stable mounting base for the cylinder, preventing operational shaking; the cylinder can output stable and controllable pushing and pulling power; and with the connector, it can reliably connect and precisely drive the base frame movement, ensuring accurate adjustment of the two tank positions and improving the precision and efficiency of tank docking.

[0013] Preferably, the connector includes a connecting plate; an extension plate is vertically connected to one end of the connecting plate; and a fixing plate is vertically connected to the end of the extension plate away from the connecting plate. The connecting plate firmly supports the cylinder piston rod, providing a solid foundation for power transmission. The extension plate can flexibly adapt to the installation distance between the piston rod and the base frame, avoiding space limitations. The fixing plate increases the contact area with the base frame to achieve a firm connection. The three components work together to ensure that the cylinder's pushing and pulling power is accurately and stably transmitted to the base frame, preventing loosening and detachment during driving, ensuring smooth and stable tank position adjustment, and facilitating precise and efficient tank docking.

[0014] Preferably, the guide assembly includes two paired semicircular ring plates connected by bolts; a panel is fixedly mounted on one side wall of each semicircular ring plate; several cylinders are fixedly mounted on the panel along the axial direction of the semicircular ring plates; and clearance holes are fixedly provided on the panel. The two paired semicircular ring plates are connected by bolts, which facilitates disassembly and assembly and is compatible with tank flanges. The cylinders on the panel can guide the two tank flanges to be precisely pre-positioned, and the clearance holes reserve space for subsequent installation of the connecting bolts. The whole assembly achieves pre-connection guidance, improving the accuracy and ease of operation of tank docking.

[0015] Preferably, a variable-diameter arc plate is fixedly provided on the side of the semi-circular ring plate away from the panel, and the smaller diameter end of the variable-diameter arc plate is fixed to the semi-circular ring plate. The design of the variable-diameter arc plate facilitates guidance during tank docking, and the method of fixing the smaller diameter end ensures a stable connection, effectively expanding the applicability of the guide component, while also allowing for a higher fit during pre-connection, further improving the accuracy of pre-positioning of the flanges of the two tanks.

[0016] As can be seen from the above technical solutions, the advantages of this invention are as follows: The circuit breaker tank docking device uses two sets of parallel rails with double sliding seats and corresponding base frames to stably support and fix the circuit breaker tank and the closing resistor combination tank, respectively, replacing the traditional crane hoisting method and avoiding the generation of metal debris from tank shaking and collision; the design of the base frame being perpendicular to the guide rail in the length direction, the power output of the translation drive mechanism, and the pre-positioning function of the guide component enable precise alignment of the two tanks, effectively solving the problems of difficult docking and insufficient precision in traditional docking, and greatly improving the efficiency and reliability of tank docking.

Detailed Implementation

[0026] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0027] like Figure 1-5 As shown, a circuit breaker tank docking device includes two sets of spaced-apart tracks arranged in parallel. Each set of tracks includes two guide rails 13. A base frame 8 for mounting and fixing the circuit breaker tank 1 is slidably mounted on the two sets of tracks. The device is characterized by having a base frame 5 for mounting and fixing the closing resistor combination tank 2 slidably mounted on the two sets of tracks. The length directions of the base frame 8 and the base frame 5 are perpendicular to the length direction of the guide rails 13. The base frame 8 is connected to a translation drive mechanism 4. Two sliding seats 7 are slidably mounted on each set of tracks; one sliding seat 7 is used to connect the base frame 5, and the other sliding seat 7 is used to connect the base frame 8. A guide assembly 14 for pre-connecting the circuit breaker tank 1 and the closing resistor combination tank 2 is installed on the circuit breaker tank 1.

[0028] The circuit breaker tank docking device uses two sets of parallel rails with double sliding seats 7 and corresponding base frames to stably support and fix the circuit breaker tank 1 and the closing resistor combination tank 2, respectively, replacing the traditional crane hoisting method and avoiding the generation of metal debris from tank shaking and collision. The design of the base frame being perpendicular to the guide rails, the power output of the translation drive mechanism 4, and the pre-positioning function of the guide component 14 enable precise alignment of the two tanks, effectively solving the problems of difficult and insufficient precision in traditional docking, and greatly improving the efficiency and reliability of tank docking.

[0029] In the above configuration, the sliding base 7 includes a mounting plate 701; each corner of the bottom surface of the mounting plate 701 is equipped with a locking slider 702; the slider 702 is slidably mounted on the guide rail 13; a linear slide rail is provided on the top surface of the mounting plate 701; the extension direction of the linear slide rail is perpendicular to the direction of the guide rail 13; one end of the base frame 5 is connected to a translation drive mechanism 12. The linear slide rail includes two opposing guide rails 703; a locking slider 704 is slidably mounted on the guide rails 703; the slider 704 is used to connect the base frame 8 and the base frame 5.

[0030] The mounting plate 701 of the sliding seat 7 provides a stable bearing base for each component. The slider 702 with locking function at the bottom corners slides along the guide rail 13, which can ensure smooth sliding and lock and fix the tank after the position is adjusted to prevent the tank from shifting. The top linear slide rail is set perpendicular to the guide rail 13, which can realize the sliding of the base frame 5 and the base frame 8 in the direction perpendicular to the guide rail 13. In conjunction with the translation drive mechanism 12 connected to the base frame 5, it can provide precise power to the base frame 5 to adjust the position, thereby realizing flexible and precise alignment of the two tanks in the front-back and left-right directions, creating conditions for subsequent precise flange docking and improving the accuracy and efficiency of tank docking. Two opposing guide rails 703 provide stable guidance for slider 704, preventing it from shifting during sliding. Slider 704 with locking function can slide smoothly along guide rails 703 to adjust the position of base frame 8 and base frame 5, and can also lock and fix it after adjustment to prevent base frame 5 and base frame 8 from shifting. At the same time, slider 704 is directly connected to base frame 8 and base frame 5, which can accurately transmit sliding action and help the circuit breaker tank 1 and closing resistor combination tank 2 achieve precise alignment in a specific direction, further ensuring the accuracy and stability of tank docking.

[0031] like Figure 3 and Figure 5As shown, the translation drive mechanism 14 and the translation drive mechanism 212 have the same structure. The translation drive mechanism 14 includes a vertical plate 401. Side plates 402 are vertically fixed on both sides of the vertical plate 401. A cylinder 403 is installed on the vertical plate 401. The piston rod end of the cylinder 403 passes through the vertical plate 401 and is connected to a connector 404 for connecting the base frame 28 and the base frame 15. The connector 404 includes a connecting plate 4041. An extension plate 4042 is vertically connected to one end of the connecting plate 4041. A fixing plate 4043 is vertically connected to the end of the extension plate 4042 away from the connecting plate 4041.

[0032] The translation drive mechanism 4 and 2 adopt the same structure, which can simplify the manufacturing process and reduce maintenance costs, eliminating the need for separate design or spare parts for the two drive mechanisms. The vertical plate 401, together with the side plates 402 that are vertically fixed on both sides, can provide a stable installation base for the cylinder 403, preventing the cylinder 403 from shaking during operation and ensuring stable power output. As a power source, the cylinder 403 can achieve smooth and controllable push-pull action. Combined with the connecting piece 404 at the end of the piston rod, it can reliably connect and accurately drive the base frame 5 or the base frame 8 to move, ensuring that the position adjustment of the circuit breaker tank 1 and the closing resistor combination tank 2 is accurate and in place during the docking process, further improving the accuracy and efficiency of tank docking. The connecting plate 4041 of the connector 404 can firmly support the piston rod of the cylinder 403, providing a reliable starting point for power transmission; the extension plate 4042 can flexibly adapt to the installation distance between the piston rod and the base frame 5 and the base frame 8, avoiding spatial limitations affecting the connection; the vertically set fixing plate 4043 can increase the contact area with the base frame, achieving a firm connection between the two and preventing the connector 404 from detaching or loosening from the base frame during the driving process. The three work together to ensure that the pushing and pulling power of the cylinder 403 is accurately and stably transmitted to the base frame, ensuring smooth movement of the circuit breaker tank 1 and the closing resistor combination tank 2 during position adjustment, and providing a reliable guarantee for the precise docking of the two tanks.

[0033] Support columns 3 are installed at the corners of the top surface of base frame 5; support columns 9 are installed at the corners of the top surface of base frame 8; lifting mechanisms are installed on the top surfaces of support columns 3 and 9. The lifting mechanism is a screw jack 10; both support columns 3 and 9 have clearance grooves to accommodate the screw of the screw jack 10. A support 11 for connecting the circuit breaker tank 1 and the closing resistor combination tank 2 is installed at the top of the screw of the screw jack 10.

[0034] The support columns 1-3 and 2-9 at the corners of base frame 1-5 and base frame 2-8 respectively provide stable corner support for the closing resistor combination tank 2 and the circuit breaker tank 1, preventing the tanks from shifting or tipping over during placement. The lifting mechanism at the top of the support columns allows for precise four-point height adjustment of the two tanks, facilitating control of the height difference and verticality of the tank flanges. This solves the problem of insufficient precision in traditional manual adjustment, further laying the foundation for precise docking of the two tanks and improving the quality and stability of the docking. A screw jack 10 is used as the lifting mechanism, offering high transmission precision and stable adjustment. It can accurately control the height and docking verticality of the circuit breaker tank 1 and the closing resistor combination tank 2, meeting the high-precision docking requirements of a flange height difference of ±0.5mm and a verticality of 89.5°-90°. The clearance grooves on support columns 1-3 and 2-9, designed to accommodate the screw, prevent interference with the screw's movement, ensuring smooth screw lifting and lowering, further guaranteeing the reliability of height adjustment and laying a solid foundation for precise docking of the two tanks. The support 11 at the top of the screw of the screw jack 10 can firmly connect the circuit breaker tank 1 and the closing resistor combination tank 2, preventing the tank from shifting or shaking during height adjustment or subsequent docking, and ensuring that the tank always maintains a stable posture. At the same time, the support 11 can achieve precise alignment between the tank and the screw jack 10, so that the height adjustment effect is accurately transmitted to the tank, ensuring the adjustment accuracy of the height difference and verticality of the flanges of the two tanks, providing a stable foundation for the subsequent precise alignment of the flanges and docking of the tanks, and further improving the reliability of the docking.

[0035] like Figure 4 As shown, the support 11 includes a base plate 1101; a vertical plate 1102 is fixed to the middle of the top surface of the base plate 1101; a through hole 1103 is provided on the upper part of the vertical plate 1102 for passing through bolts connecting the circuit breaker tank 1 and the closing resistor combination tank 2; and a reinforcing rib 1104 is installed between the vertical plate 1102 and the base plate 1101. The base plate 1101 of the support 11 provides stable support for the overall structure, ensuring that it is firmly installed at the top of the screw jack 10. The vertically fixed vertical plate 1102 in the middle and the through hole 1103 at the top can be firmly connected to the circuit breaker tank 1 and the closing resistor combination tank 2 by bolts, preventing the tank from shifting during adjustment or docking. The reinforcing rib 1104 between the vertical plate 1102 and the base plate 1101 can significantly enhance the overall structural strength of the support 11, prevent deformation under stress, and further ensure the stability and reliability of the support 11 in supporting the tank. This lays a solid foundation for the subsequent precise adjustment of the height and verticality of the two tanks and the docking of the tanks, reducing docking deviations caused by problems with the support 11.

[0036] like Figure 6-7As shown, the guide assembly 14 includes two paired semicircular ring plates 1401, which are connected by bolts 1402. A panel 1403 is fixedly mounted on one side wall of each semicircular ring plate 1401. Several cylinders 1404 are fixedly mounted on the panel 1403 along the axial direction of the semicircular ring plate 1401. A clearance hole 1405 is fixedly opened on the panel 1403. A variable diameter arc plate 1406 is fixedly mounted on the side of the semicircular ring plate 1401 away from the panel 1403, and the smaller diameter end of the variable diameter arc plate 1406 is fixed to the semicircular ring plate 1401. Two paired semi-circular ring plates 1401 are connected by bolts 1402, facilitating disassembly and assembly and adapting to tank flanges. The cylinder 1404 on the panel 1403 guides the two tank flanges to precise pre-positioning, and the clearance hole 1405 reserves space for the subsequent installation of the docking bolts 1402. The overall design achieves pre-connection guidance, improving the accuracy and ease of operation during tank docking. The design of the variable diameter arc plate 1406 facilitates guidance during tank docking, and the fixed method at the small diameter end ensures a stable connection, effectively expanding the applicability of the guide component 14, while also improving the fit during pre-connection and further enhancing the accuracy of pre-positioning of the two tank flanges. In use, first insert the cylinder 1404 into the bolt hole of the flange of the circuit breaker tank 1, and then connect the two semi-circular ring plates 1401 with bolts 1402; after the circuit breaker tank 1 and the closing resistor combination tank 2 are connected, insert the cylinder 1404 into the bolt hole of the flange of the closing resistor combination tank 2, and then connect the circuit breaker tank 1 and the closing resistor combination tank 2 through the clearance hole 1405. After that, remove the guide assembly 14 and continue to install the remaining connecting bolts.

[0037] The operating method of this circuit breaker tank connection device is as follows: Assembly and preparation of the device: Assemble the circuit breaker tank docking device according to the assembly requirements, and connect the device power supply and gas pipe; at the same time, check the locking status of slider 1 702 and slider 2 704 with locking function, and initially keep them unlocked.

[0038] Tank hoisting and fixing: Use a crane to hoist the circuit breaker tank 1 and the closing resistor combination tank 2 respectively. Place the circuit breaker tank 1 on the top surface of the second base frame 8 and fix it with bolts through the vertical plate 1102 of the top support 11 of the corner support column 29 of the second base frame 8; place the closing resistor combination tank 2 on the top surface of the first base frame 5 and fix it with bolts through the vertical plate 1102 of the top support 11 of the corner support column 3 of the first base frame 5.

[0039] Preliminary gap adjustment and height verticality calibration: Start the translation drive mechanism 4, control the cylinder 403 to push the base frame 8 to slide along the guide rail 13, so that the gap between the two tank flanges is adjusted to about 100mm; control the motors of each screw lift 10 to drive the support 11 and the tank to lift and lower, adjust the height and verticality of the two tank flanges, and ensure that the height difference is controlled within ±0.5mm and the verticality is between 89.5° and 90°. After the adjustment is completed, lock the slider 702.

[0040] Left and right alignment adjustment: Start the translation drive mechanism 12, control the cylinder 403 to push the base frame 5 to slide along the guide rail 703 on the top surface of the sliding seat 7, adjust the left and right positions of the closing resistor combination tank 2, so that the flanges of the two tanks are aligned in the left and right direction, and the error is controlled within ±0.5mm. After the adjustment is completed, lock the slider 704.

[0041] Pre-connection and precise flange positioning: The cylinder 1404 of the pre-connection component 14 is inserted into the bolt hole of the flange of the circuit breaker tank 1 in advance, and then the two semi-circular ring plates 1401 are spliced ​​and fixed with bolts 1402; the translation drive mechanism 1 4 is started again to push the base frame 2 8 to make the two tank flanges gradually approach each other until the cylinder 1404 is precisely inserted into the bolt hole of the flange of the closing resistor combination tank 2, thus completing the precise pre-positioning of the two tank flanges.

[0042] Bolt installation and removal of pre-connected components: Start the translation drive mechanism 14, pull the base frame 28 to widen the distance between the two tank flanges to about 300mm, insert some of the butt bolts through the clearance holes 1405 on the panel 1403 and fix them initially; then remove the fixing bolts 1402 of the pre-connected component 14, remove the two semi-circular ring plates 1401, and continue to install the remaining butt bolts, ensuring that all bolts are inserted into the flange holes.

[0043] Final docking: Reactivate the translation drive mechanism 4 to push the base frame 8 to reduce the flange spacing to about 100mm, and check the installation of all bolts; finally, use the mating clamp to further connect and tighten the flanges of the two tanks until there is no gap between the flanges, and the tank docking is completed.

[0044] II. Advantages of the device This circuit breaker tank connection device has significant advantages over the traditional crane assembly method, and can comprehensively solve the pain points of circuit breaker tank connection: High stability: Through two sets of parallel rails, a sliding seat 7 with locking function and a special base frame, stable support is provided for the circuit breaker tank 1 and the closing resistor combination tank 2, which replaces the traditional crane hoisting, avoids tank collision caused by hoisting sway, effectively reduces the generation of metal debris, and ensures the subsequent withstand voltage pass rate of the circuit breaker. High docking accuracy: The screw jack 10 can precisely adjust the height difference between the two tanks to ±0.5mm and the verticality to 89.5°-90°. Combined with the translation drive mechanism 1 4 and translation drive mechanism 2 12 driven by cylinder 403 and the linear slide rail perpendicular to guide rail 1 13, the tanks can be precisely aligned in multiple directions, front-back and left-right, with a left-right error of ±0.5mm. In addition, the cylindrical guide design of the pre-connection component 14 can avoid docking misalignment, further improving the accuracy of flange pre-positioning and overall docking, and completely solving the problem of insufficient accuracy of traditional manual adjustment. Efficient and convenient operation: Mechanized drive replaces manual assistance, eliminating the need to repeatedly start and stop the crane. Furthermore, the translation drive mechanism 14 and translation drive mechanism 212 have a unified structure, and the pre-connected components can be flexibly disassembled and assembled without hindering bolt installation. This simplifies the production, maintenance, and tank docking process, significantly improves docking efficiency, reduces reliance on operator experience, and ensures assembly consistency. Reliable structure with wide adaptability: The reinforcing rib 1104 design of the support 11 and the locking function of the slider further enhance the stability of the device and prevent the tank from shifting during adjustment or docking; the variable diameter arc plate of the pre-connected component can be adapted to flanges of different diameters, expanding the applicability of the device and ultimately comprehensively improving the accuracy, reliability and production efficiency of the circuit breaker tank docking, adapting to the batch assembly needs in the factory.
