Description

Technical Field

[0001] This utility model relates to the field of tank circuit breaker housing production, and more specifically, to a clamping device that can be adapted to the processing of different tank circuit breaker housing sizes. Background Technology

[0002] Circuit breakers belong to the category of protective electrical appliances. In the event of overload, over-limit, or short circuit in a circuit system, they promptly identify the fault point and disconnect the circuit, ensuring the safety of other parts of the power grid. Therefore, circuit breakers are one of the key pieces of equipment in the power grid, playing a crucial role in protecting the grid's safety. Years of research have confirmed that mechanical factors are a significant cause of circuit breaker damage; auxiliary circuits and control circuits are also contributing factors. Tank-type circuit breakers are widely used in AC areas of ultra-high voltage substations or converter stations due to their low center of gravity, good seismic performance, simple installation, and low cost.

[0003] During the production and processing of tank-type circuit breaker housings, they need to be clamped and fixed. Existing clamping and fixing devices for tank-type circuit breaker housings can only clamp and fix housings that match them, which is limited. When processing another batch of tank-type circuit breaker housings of different sizes, it is also necessary to change the clamping device that matches them, which is very inconvenient. Therefore, we have made an improvement and proposed a clamping device that can be adapted to the processing of tank-type circuit breaker housings of different sizes. Utility Model Content

[0004] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0005] A clamping device that can be adapted to process different tank-type circuit breaker housing sizes can improve the above-mentioned problems.

[0006] The present invention is as follows:

[0007] The device includes a base, a U-shaped seat fixedly mounted on the top of the base, a first motor fixedly mounted on the side wall of the U-shaped seat, a bidirectional threaded rod rotatably connected to the output end of the first motor, a movable column threaded at both ends of the bidirectional threaded rod, a sliding column slidably connected inside the movable column, a gripper fixedly mounted on the top of the sliding column, a first L-shaped frame and a second L-shaped frame fixedly mounted on the top of the base, sliders slidably connected to both the first and second L-shaped frames, a guide rod fixedly mounted on the side wall of the slider, a connecting plate fixedly mounted on the front of the sliding column, an L-shaped plate fixedly mounted on the front of the connecting plate, the L-shaped plate slidably connected to the guide rod, and a driving mechanism provided on the first L-shaped frame.

[0008] As a preferred technical solution of this utility model, the driving mechanism includes a second motor and a first threaded rod. The second motor is fixedly installed on the top of the first L-shaped frame, the first threaded rod is rotatably connected to the first L-shaped frame, the output end of the second motor is fixedly connected to the first threaded rod, and the first threaded rod is threadedly connected to a slider that slides on the first L-shaped frame.

[0009] As a preferred technical solution of this utility model, a second threaded rod is rotatably connected to the second L-shaped frame, and the second threaded rod is threadedly connected to the slider that slides on the second L-shaped frame.

[0010] As a preferred technical solution of this utility model, a first synchronous pulley is fixedly installed at the bottom of the first threaded rod, and a second synchronous pulley is fixedly installed at the bottom of the second threaded rod. The first synchronous pulley and the second synchronous pulley are connected by a synchronous belt.

[0011] As a preferred technical solution of this utility model, the bottoms of both the first synchronous wheel and the second synchronous wheel are rotatably connected to the base.

[0012] As a preferred technical solution of this utility model, a placement platform is fixedly installed on the base.

[0013] As a preferred technical solution of this utility model, a switch group is provided on the side wall of the first L-shaped frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In the solution of this utility model:

[0016] 1. A second motor drives the first threaded rod to rotate (simultaneously, the first threaded rod also drives the first synchronous pulley to rotate, the first synchronous pulley drives the second synchronous pulley to rotate via a synchronous belt, and the second synchronous pulley drives the second threaded rod to rotate). The rotation of both the first and second threaded rods simultaneously moves the slider, which in turn moves the guide rod, which in turn moves the L-shaped plate, which in turn moves the connecting plate, which in turn moves the sliding column, which in turn moves the gripper, causing the gripper to move to a suitable height (the larger the size of the tank-type circuit breaker housing, the higher the gripper needs to be, and vice versa). This allows for the clamping and fixing of tank-type circuit breaker housings of different sizes, solving the limitation of existing technologies that can only clamp and fix housings of one size.

[0029] Example:

[0030] like Figure 1-5 As shown, this embodiment proposes a clamping device adaptable to the processing of different tank-type circuit breaker housing sizes. It includes a base 1, a U-shaped seat 2 fixedly mounted on the top of the base 1, a first motor 17 fixedly mounted on the side wall of the U-shaped seat 2, a bidirectional threaded rod 3 rotatably connected to the output end of the first motor 17, the first motor 17 driving the bidirectional threaded rod 3 to rotate, and movable columns 4 threadedly connected to the threads at both ends of the bidirectional threaded rod 3. The rotation of the bidirectional threaded rod 3 drives the movable columns 4 to move inward simultaneously. A sliding column 5 is slidably connected inside the movable column 4, the movement of the movable column 4 driving the sliding column 5, and a gripper 6 fixedly mounted on the top of the sliding column 5. The sliding column 5 drives the gripper 6, causing the gripper 6 to clamp the tank-type circuit breaker housing, allowing subsequent processing operations to be performed. The unit is fixedly equipped with a first L-shaped frame 7 and a second L-shaped frame 8. Both the first L-shaped frame 7 and the second L-shaped frame 8 are slidably connected to sliders 9. A guide rod 10 is fixedly installed on the side wall of slider 9. Slider 9 drives guide rod 10. A connecting plate 11 is fixedly installed on the front of sliding column 5. An L-shaped plate 12 is fixedly installed on the front of connecting plate 11. L-shaped plate 12 is slidably connected to guide rod 10. Guide rod 10 drives L-shaped plate 12. L-shaped plate 12 drives connecting plate 11. Connecting plate 11 drives sliding column 5. Sliding column 5 drives gripper 6, so that gripper 6 moves to a suitable height. This enables clamping and fixing of tank-type circuit breaker housings of different sizes, solving the limitation of existing technology which can only clamp and fix housings of one size.

[0031] The drive mechanism includes a second motor 18 and a first threaded rod 20. The second motor 18 is fixedly mounted on the top of the first L-shaped frame 7, and the first threaded rod 20 is rotatably connected to the first L-shaped frame 7. The output end of the second motor 18 is fixedly connected to the first threaded rod 20, and the first threaded rod 20 is threadedly connected to a slider 9 that slides on the first L-shaped frame 7.

[0032] A second threaded rod 13 is rotatably connected to the second L-shaped frame 8. The second threaded rod 13 is threadedly connected to the slider 9 that slides on the second L-shaped frame 8. When the second threaded rod 13 rotates, it drives the slider 9 to move.

[0033] A first synchronous pulley 14 is fixedly installed at the bottom of the first threaded rod 20. The first threaded rod 20 drives the first synchronous pulley 14 to rotate. A second synchronous pulley 15 is fixedly installed at the bottom of the second threaded rod 13. The first synchronous pulley 14 and the second synchronous pulley 15 are connected by a synchronous belt 16. The first synchronous pulley 14 drives the second synchronous pulley 15 to rotate through the synchronous belt 16.

[0034] The bottoms of the first synchronous pulley 14 and the second synchronous pulley 15 are rotatably connected to the base 1.

[0035] A placement platform 21 is fixedly installed on the base 1. The tank-type circuit breaker housing is placed on the placement platform 21 and clamped for subsequent processing.

[0036] A switch group 19 is provided on the side wall of the first L-shaped frame 7, and the switch group 19 is electrically connected to the motor.

[0037] Specifically, the clamping device, which can be adapted to process different tank-type circuit breaker housing sizes, is used as follows: First, adjust the height of the gripper 6 according to the size of the tank-type circuit breaker housing. Then, start the second motor 18. The second motor 18 drives the first threaded rod 20 to rotate (at the same time, the first threaded rod 20 also drives the first synchronous pulley 14 to rotate, the first synchronous pulley 14 drives the second synchronous pulley 15 to rotate through the synchronous belt 16, and the second synchronous pulley 15 drives the second threaded rod 13 to rotate). While the first threaded rod 20 and the second threaded rod 13 are rotating, they both drive the slider 9 to move. The slider 9 drives the guide rod 10, the guide rod 10 drives the L-shaped plate 12, the L-shaped plate 12 drives the connecting plate 11, and the connecting plate 11 drives the slider 9 to move. The column 5 and sliding column 5 drive the gripper 6 to move the gripper 6 to a suitable height (the larger the size of the tank-type circuit breaker housing, the higher the gripper 6 should be, and vice versa), which enables the clamping and fixing of tank-type circuit breaker housings of different sizes, solving the limitation of existing technologies that can only clamp and fix housings of one size. Then, the tank-type circuit breaker housing is placed on the placement platform 21, and then the first motor 17 is started. The first motor 17 drives the bidirectional threaded rod 3 to rotate, and the rotation of the bidirectional threaded rod 3 drives the moving column 4 to move inward at the same time. The movement of the moving column 4 drives the sliding column 5, and the sliding column 5 drives the gripper 6, so that the gripper 6 clamps the tank-type circuit breaker housing, and then subsequent processing operations can be carried out.

[0038] All technical features in this embodiment can be freely combined according to actual needs.

[0039] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
