Description

Technical Field

[0001] This utility model relates to the field of vacuum interrupter opening technology, and in particular to an auxiliary opening device for a vacuum interrupter. Background Technology

[0002] The separation assembly is a key process in the production of vacuum interrupters, mainly used to fix the relative positions of core components and ensure the separation of the moving and stationary contact plates. The core operation process is as follows: first, the relative positions of the moving conductive rod and the fixed ring are fixed using a limiting mold; after the bellows is in a compressed state and the positions of the moving conductive rod and the fixed ring are fixed, a gasket is inserted into the annular groove designed for the moving conductive rod. The mechanical limiting action of the gasket (resisting the fixed ring) maintains the compressed state of the bellows and the separation gap of the contact plates.

[0003] Before proceeding to the next process, the gasket must be removed. In the existing technology, this removal process relies too heavily on manual operation. Specifically, the operator uses a hook-type tool, screws one end onto the moving conductive rod with threads, and hooks the other end to a fixed location such as a wall. Then, the operator manually pulls the moving conductive rod axially to remove the gasket.

[0004] However, this operating method has obvious drawbacks: the manual pulling process requires overcoming the elastic force of the corrugated pipe, which consumes a lot of physical strength for the operator. Not only is the labor intensity extremely high, but the operating efficiency is also extremely low, making it difficult to meet the needs of large-scale production. Utility Model Content

[0005] The purpose of this invention is to provide an auxiliary opening device for a vacuum interrupter, which uses cylinder power to replace manual labor to open the moving conductive rod, thereby achieving highly efficient gasket removal.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is: an auxiliary opening device for a vacuum interrupter, including a horizontally arranged semi-circular support cylinder for supporting the vacuum interrupter, one end of the semi-circular support cylinder being vertically connected to the surface of a baffle plate, the baffle plate having a vertically arranged U-shaped notch extending upward to its edge and only allowing the moving conductive rod and the gasket to pass through, the baffle plate having an opening cylinder with its output end facing the end of the moving conductive rod on the side away from the semi-circular support cylinder, and a transmission component detachably connected to the end of the moving conductive rod on the output end of the opening cylinder.

[0007] As a further improvement of this utility model, the baffle is provided with two positioning guide blocks on the side of the plate away from the semi-circular support cylinder, which respectively contact the outer walls of the two sides of the gasket.

[0008] As a further improvement of this utility model, a guide groove located below the gasket is provided on the baffle plate surface between the two positioning guide blocks.

[0009] As a further improvement of this utility model, the transmission assembly includes a pull rod coaxially arranged with the moving conductive rod. One end of the pull rod is detachably connected to the end of the moving conductive rod through a conductive rod connecting part, and the other end is detachably connected to the output end of the opening cylinder through a connecting rod.

[0010] As a further improvement of this utility model, the pull rod is provided with a locking block at one end near the connecting rod, and the connecting rod body is provided with a T-shaped bayonet for the locking block to be engaged.

[0011] As a further improvement of this utility model, the connecting rod is detachably connected to the output end of the pull-out cylinder via a cylinder connecting part provided at its end.

[0012] As a further improvement of this utility model, it also includes: an L-shaped support plate for mounting the semi-circular support cylinder, and a cylinder bracket for mounting the opening cylinder.

[0013] As a further improvement of this utility model, the bottom plate of the L-shaped support plate is provided with an adjustment bolt mounting port extending along the axial direction of the vacuum interrupter.

[0014] As a further improvement of this utility model, the upper edge of the vertical plate of the L-shaped support plate extends downward to provide a support cylinder installation notch, and the vertical plate of the L-shaped support plate is fixedly connected to the baffle by bolts.

[0015] Beneficial effects Compared with the prior art, the advantages of the auxiliary opening device for a vacuum interrupter of this utility model are as follows: 1. After the vacuum interrupter is placed on the semi-circular support cylinder, the end face of the vacuum interrupter is held against by a baffle, and the moving conductive rod and the gasket are passed through the U-shaped notch. The moving conductive rod is connected to the output end of the opening cylinder through the transmission component to form a power transmission path. As a result, the operator only needs to control the switch of the opening cylinder to control the power of the opening cylinder to open the moving conductive rod. The gasket can be removed without the need for manual external force, which fundamentally solves the pain point of the existing process.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; of course, they can also refer to a mechanical connection or an electrical connection; furthermore, they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] Embodiments of the present invention will now be described with reference to the accompanying drawings.

[0023] Example: The specific embodiments of this utility model are as follows: Figure 1-2 As shown, an auxiliary opening device for a vacuum interrupter includes a horizontally arranged semi-circular support cylinder 2 for supporting the vacuum interrupter. Because the semi-circular support cylinder 2 supports the vacuum interrupter, its opening faces upwards. In this embodiment, the semi-circular support cylinder 2 is shaped to semi-enclose a cylindrical cavity, and the opening size of the cylindrical cavity is adapted to the vacuum interrupter. This semi-enclosed structure allows for easy placement and removal of the vacuum interrupter, while also positioning it to prevent movement during the opening process.

[0024] One end of the semi-circular support cylinder 2 is perpendicularly connected to the surface of a vertically arranged baffle 3, and the baffle 3 has a vertically extending U-shaped notch 31 extending upward to its edge. The U-shaped notch 31 allows only the moving conductive rod 7 and the gasket 8 to pass through. On the side of the baffle 3 away from the semi-circular support cylinder 2, there is a pull-open cylinder 6 with its output end facing the end of the moving conductive rod 7, and the output end of the pull-open cylinder 6 is equipped with a transmission assembly that is detachably connected to the end of the moving conductive rod 7.

[0025] When using this device to remove the gasket, first place the vacuum interrupter on the semi-circular support cylinder 2; then, press the baffle 3 against the end face of the vacuum interrupter and allow the moving conductive rod 7 and the gasket 8 to pass through the U-shaped notch; then, connect the end of the moving conductive rod 7 to the output end of the opening cylinder 6 through the transmission assembly to form a power transmission path; finally, the operator only needs to control the switch of the opening cylinder to control the power of the opening cylinder 6 to open the moving conductive rod 7. At this time, the gasket 8 installed in the annular groove of the moving conductive rod 7 is no longer mechanically limited by the combined force of the moving conductive rod 7, the fixing ring 9 and the bellows, and will fall freely, thereby realizing the removal of the gasket 8.

[0026] Compared to the existing method of manually pulling the conductive rod 7 to remove the gasket, this device uses pneumatic cylinder power instead of manual pulling force. Operators no longer need to manually apply external force to overcome the elastic force of the bellows; they can simply control the opening cylinder 6 to remove the gasket 8, significantly reducing the physical exertion and labor intensity. Simultaneously, the stable power output of the opening cylinder 6 avoids the individual differences and slow pace inherent in manual operation, consistently improving single-process efficiency and better meeting the needs of large-scale production. Therefore, this device specifically addresses the pain points of existing technologies, fundamentally changing the current method of operation that heavily relies on manual pulling, and completely solving the problems of high labor intensity and low efficiency.

[0027] In this device, to guide the pad 8 downwards, the baffle 3 has two positioning guide blocks 32 on the side facing away from the semi-circular support cylinder 2, which respectively contact the outer walls of the two side edges of the pad 8. At the same time, the baffle 3 between the two positioning guide blocks 32 has a guide groove 33 located below the pad 8.

[0028] Regarding the specific structure of the transmission assembly, it includes a pull rod 4 coaxially arranged with the moving conductive rod 7. One end of the pull rod 4 is detachably threaded to the end of the moving conductive rod 7 via a conductive rod connecting part 41, and the other end is detachably connected to the output end of the opening cylinder 6 via a connecting rod 5. In this embodiment, the pull rod 4 has a locking block 42 at the end near the connecting rod 5, and the connecting rod 5 has a T-shaped bayonet 51 for the locking block 42 to engage. Simultaneously, the connecting rod 5 is detachably threaded to the output end of the opening cylinder 6 via a cylinder connecting part 52 at its end. This design allows the moving conductive rod 7 and the output end of the opening cylinder 6 to form a power transmission path, and makes the assembly and disassembly between the two very convenient. In addition, depending on the distance between the moving conductive rod 7 and the opening cylinder 6, different lengths of pull rod 4 and connecting rod 5 can be replaced; or the thread fit depth between the conductive rod connecting part 41 and the end of the moving conductive rod 7, and between the cylinder connecting part 52 and the output end of the opening cylinder 6 can be finely adjusted, so that the device has good adjustability.

[0029] It is important to note that: In order to install and fix the semi-circular support cylinder 2 and the pull-open cylinder 6, the auxiliary pull-opening device in this embodiment further includes: an L-shaped support plate 1 for installing the semi-circular support cylinder 2, and a cylinder bracket 61 for installing the pull-open cylinder 6.

[0030] The L-shaped support plate 1 has an adjusting bolt mounting port 11 extending axially along the vacuum interrupter chamber on its base plate. The distance between the fixed semi-circular support cylinder 2 and the opening cylinder 6 can be adjusted axially along the vacuum interrupter chamber by adjusting the bolts in the mounting port 11. Regarding the installation of the semi-circular support cylinder 2, the upper edge of the vertical plate of the L-shaped support plate 1 extends downwards to provide a support cylinder mounting notch 12, and the vertical plate of the L-shaped support plate 1 is fixedly connected to the baffle 3 by bolts.

[0031] The present invention has been described above in conjunction with the preferred embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations made in accordance with the essence of the present invention.
