[0001] This utility model belongs to the technical field of circuit breakers, specifically relating to a positioner for assembling the moving side components of a circuit breaker. Background Technology

[0002] Currently, when assembling the moving side of a circuit breaker, three insulating support cylinders need to be assembled onto the support base to form the moving side assembly. Then, the entire moving side assembly needs to be rotated 180 degrees so that the insulating support cylinders face down before they can be inserted into the crank arm box of the moving side. During this process, because the moving side assembly is relatively large in size and weight, three operators need to work with a crane to complete the rotation of the moving side assembly. This is time-consuming, labor-intensive, and poses safety risks. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a positioner for assembling the moving side components of a circuit breaker. By manually operating the positioner, the moving side components can be rotated 180 degrees, thereby enabling single-person rotation operation, saving manpower and resources, reducing operational complexity, and making it more practical.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A positioner for assembling moving-side components of a circuit breaker includes a movable base, a gantry-shaped bracket at one end of the movable base, a movable block inside the gantry-shaped bracket, the bottom surface of the movable block being connected to the gantry-shaped bracket via a lifting mechanism, a rotating mechanism at the center of the movable block, and two forked arms spaced parallel to each other on one side of the movable block, both extending toward the other end of the movable base for supporting the moving-side components. The lifting mechanism is used to drive the moving block, along with the fork arm and the rotating mechanism, to move up and down along the portal frame. The rotating mechanism is used to drive the fork arm to rotate along its axial direction.

[0005] Furthermore, the rotating mechanism includes a worm gear reducer, the input shaft of which is connected to a handwheel, and its output shaft passes through a moving block and is connected to the center of a support plate. A fork arm is connected to each end of the support plate. A positioning hole is provided on each side of the support plate near the output shaft, and a fixing hole is also provided at the position of the moving block. The pin passes through the positioning hole and cooperates with the corresponding fixing hole to realize the rotation limit of the support plate. Turn the handwheel, and the worm gear reducer will drive the support plate and the two fork arms to rotate.

[0006] Furthermore, the input shaft is connected to one end of a connecting rod via a coupling, and the other end of the connecting rod is connected to a handwheel, which is exposed on the side of the portal frame.

[0007] Furthermore, the lifting mechanism includes a jack connected to the bottom surface of the movable block. The movable block has a cuboid structure, and two bearings are spaced apart on its side that mates with the side wall of the portal frame. The inner sides of both side arms of the portal frame are provided with slides, the cross-section of which is U-shaped, and each bearing is fitted inside the corresponding slide.

[0008] Furthermore, each of the fork arms is provided with multiple threaded fixing holes, and the moving side assembly is fixed to the fork arm by the cooperation of bolts with the threaded fixing holes.

[0009] Furthermore, the movable base includes a base plate, with a caster wheel at each of the four corners of the base plate, and the portal bracket is provided at one end of the base plate by multiple reinforcing ribs.

Detailed Implementation

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following embodiments, in conjunction with the accompanying drawings, specifically describe the assembly work of the vacuum bulb for a circuit breaker according to this utility model. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0014] like Figure 1-3 As shown, this utility model provides a positioner for assembling the moving side assembly of a circuit breaker, including a movable base 1. A portal frame 2 is provided at one end of the movable base 1. A movable block 3 is provided inside the portal frame 2. The bottom surface of the movable block 3 is connected to the portal frame 2 through a lifting mechanism. A rotating mechanism is provided at the center of the movable block 3. Two fork arms 4 are arranged parallel to each other on one side of the movable block 3, both extending towards the other end of the movable base 1 to support the moving side assembly 5. The lifting mechanism is used to drive the movable block 3, together with the fork arms 4 and the rotating mechanism, to move up and down along the portal frame 2. The rotating mechanism is used to drive the fork arms 4 to rotate along their axial direction. In this way, by using the lifting mechanism to adjust the fork arms to an appropriate height so that they can cooperate with the support arm seat on the moving side assembly, and fix the moving side assembly to the fork arms, the rotating mechanism is used to drive the moving side assembly to rotate 180 degrees to prepare for subsequent insertion into the crank arm box. This allows for single-person rotation operation, saving manpower and resources, and significantly reducing safety hazards during the rotation process, making it more practical.

[0015] Specifically as follows: The mobile base 1 can adopt a four-wheel drive structure, such as including a base plate, with a universal wheel set at each of the four corners of the base plate so that the driving side components can be moved later. The portal bracket 2 can be set at one end of the base plate with multiple reinforcing ribs to increase the fastness.

[0016] The lifting mechanism includes a jack 6 connected to the bottom of the movable block 3. The movable block 3 has a cuboid structure, and two bearings 7 or rollers are spaced apart on its side that mates with the side wall of the portal frame 2. These rollers can be mounted on the movable block 3 via a pivot. The inner sides of the two side arms of the portal frame 2 are each provided with a slide rail 201, which has a U-shaped cross-section. Each bearing 7 is fitted inside the corresponding slide rail 201. Thus, the jack 6 can be a foot-operated pressing mechanism, driven by hydraulic oil. By foot-operated, the extension height of the piston rod of the jack 6 is adjusted, thereby moving the movable block 3 along with the fork arm 4 along the portal frame 2 to a suitable height so that the fork arm 4 can engage with the support seat of the moving side assembly 5 for bolt tightening.

[0017] The rotating mechanism includes a worm gear reducer 8, which is located at the center of the back of the movable block 3. Its input shaft is connected to one end of a connecting rod via a coupling, and the other end of the connecting rod is connected to a handwheel 9. Its output shaft passes through the movable block 3 and is connected to the center of the support plate 10. A fork arm is connected to each end of the support plate 10. At the same time, a positioning hole 11 is provided on each side of the support plate 10 near the output shaft, and a fixing hole is also provided at the corresponding position of the movable block 3. A pin passes through the positioning hole and engages with the corresponding fixing hole to limit the rotation of the support plate 10. In this way, rotating the handwheel 9 will drive the support plate 10 and the two fork arms 4 to rotate through the worm gear reducer 8, which will drive the moving side assembly connected to the fork arms to achieve the flipping operation.

[0018] For ease of operation, the handwheel 9 needs to be exposed on the side of the gantry bracket 2. At the same time, multiple threaded fixing holes are opened on each fork arm 4. The moving side component 5 and the fork arm 4 are fixed by the cooperation of bolts and threaded fixing holes.

[0019] When using the positioner of this utility model to perform a flipping operation, the specific steps are as follows: First, use the foot pedal to adjust the extension height of the piston rod of the jack, thereby moving the moving block along the fork arm along the portal frame to adjust the fork arm to the appropriate height; Then move the positioner so that the fork arm is inserted into the support position of the moving side assembly, and then use bolts to fix the moving side assembly to the fork arm, such as... Figure 4 As shown; Then, turning the handwheel causes the worm gear reducer to rotate the fork arm and moving side assembly 180 degrees. Figure 5 As shown, the pin is then inserted into the positioning hole and its corresponding fixing hole to achieve the rotation limit of the fork arm; Finally, the positioner is moved to transport the flipped moving side component to the crank arm box station to complete the assembly of the two.
