Description

Technical Field

[0001] This application relates to the technical field of isolating contact installation, and in particular to an isolating contact installation device. Background Technology

[0002] Isolating contacts are typically circuit breakers mounted on utility poles, creating a visible and obvious disconnect point in high-voltage or low-voltage circuits to ensure the safe operation and maintenance of the power system. Isolating contacts must be able to withstand certain voltage and current and provide sufficient insulation in their open state to ensure safety. The assembly of isolating contacts in related technologies usually involves the clamping force created by the tension generated by the deformation of multiple pairs of contact fingers and springs. Because each pair of contact fingers is equipped with a spring, the installation process typically requires one person to overcome the spring tension while another person assists in placing the contact finger into the contact finger seat.

[0003] However, this installation method results in significant overall elasticity, making manual installation difficult and prone to instability in the installation accuracy of the isolating contact during the process, which is insufficient to meet the needs of large-scale production. Manual installation also suffers from poor clamping accuracy and cannot achieve rapid installation, limiting production flexibility and hindering the further development of isolating contact installation.

[0033] The following combination Figures 1 to 5 This application will be described in further detail.

[0034] This application provides an isolation contact mounting device.

[0035] refer to Figure 1 and Figure 2This installation equipment comprises a workbench 1, a first supporting plate 3, a second supporting plate 4, a first cylinder 5, a second cylinder 6, a first placement plate 7, a second placement plate 8, and a support plate a9. The isolating contact consists of an isolating crank arm 11, an isolating connecting plate 12, an isolating slider 13, an isolating insulating pull rod 14, and an isolating pin shaft 15. The first supporting plate 3 and the second supporting plate 4 are correspondingly positioned above the workbench 1. The first supporting plate 3 is fixedly connected to the workbench 1, and the second supporting plate 4 is slidably connected to the workbench 1. The first cylinder 5 and the second cylinder 6 are positioned on opposite sides of the workbench 1. The protruding end of the first cylinder 5 passes through the first supporting plate 3 and is fixedly connected to the second supporting plate 4. The protruding end of the second cylinder 6 passes through the second supporting plate 4 and is movably engaged with the isolating pin shaft 15, achieving the effect of automatically and accurately completing the installation of the isolating contact. This is because the first cylinder 5 can move the second supporting plate 4, and the second cylinder 6 can install the isolating pin shaft 15 into place. The coordinated operation of these components enables the installation of the isolating contact. (Reference) Figure 1 and Figure 2 The worktable 1 includes a slide groove 101, a slide rail 102, a support plate 2, and a reinforcing plate 201. Two slide grooves 101 are machined at intervals on the upper surface of the worktable 1, providing track space for the sliding of the second support plate 4. The slide groove 101 can be a dovetail groove, which offers good stability and prevents the second support plate 4 from derailing during sliding; alternatively, it can be a rectangular groove, which is easier to manufacture. The slide rail 102 is set within the slide groove 101 and is generally made of a high-hardness, smooth-surface metal material, such as stainless steel. It works in conjunction with the slide groove 101 to ensure smoother sliding of the second support plate 4. The support plate 2 is located on one side of the worktable 1 and serves to support some components or assist in installation operations. The reinforcing plate 201 is used to fix the support plate 2 and the worktable 1. It is usually a triangular plate; the triangle provides stability and enhances the firmness of the connection between the support plate 2 and the worktable 1. The combination of the receiving plate 2 and the reinforcing plate 201 makes the structure of the workbench 1 more stable, which helps to improve the overall stability and reliability of the equipment. (Reference) Figure 1 and Figure 2The first supporting plate 3 includes a stepped groove a301, a stepped groove b302, a connecting hole 340, a pin hole a303, and a limiting pin. Stepped grooves a301 and b302 are spaced apart on the same vertical surface of the first supporting plate 3. The bottom surface of stepped groove a301 is flat, and both sides of the flat surface are stepped, a design that facilitates the placement and positioning of components such as the isolation slider 13. It can be a right-angled stepped shape, facilitating processing and precise placement of parts; or it can be a rounded stepped shape, reducing collision damage during component placement. Stepped groove b302 connects with stepped groove a301, and the two work together to better accommodate and fix different isolation connecting plates 12 and other components. The connecting hole 340 is located below the first supporting plate 3 and above one corner of the second supporting plate 4, for the protruding ends of the first cylinder 5 and the second cylinder 6 to pass through. The hole diameter is determined according to the size of the cylinder protruding ends to ensure that the cylinders can pass through smoothly and connect tightly. Two pin holes a303 are spaced apart on both sides above the first supporting plate 3, each containing a limiting pin. These limiting pins are typically cylindrical metal rods, and their function is to limit the position of the second supporting plate 4, preventing excessive movement. These components work together to ensure that the first supporting plate 3 can effectively place and position components, and also cooperate with other components to ensure the normal operation of the equipment. (Reference) Figure 3 and Figure 4 The second abutment plate 4 includes a slider 402, a mounting groove 403, a connecting hole 340, a pin hole b401, and a limiting pin. The slider 402 is located at both ends below the second abutment plate 4 and is installed in conjunction with the slide rail 102, allowing the second abutment plate 4 to slide smoothly on the worktable 1. The slider 402 is typically made of wear-resistant plastic or alloy material to reduce friction with the slide rail 102. The mounting groove 403 is located on one side of the second abutment plate 4, corresponding to the stepped groove a301, and is used to place components such as the isolation connecting plate 12. Its shape and size are designed according to the size and shape of the isolation connecting plate 12 to ensure accurate placement. The connecting hole 340 and the pin hole b401 function similarly to those on the first abutment plate 3. The connecting hole 340 allows the cylinder extension end to pass through, and the pin hole b401 contains a limiting pin for positioning. The second supporting plate 4, through these components, works in conjunction with the first supporting plate 3, the worktable 1, and the cylinder to complete the installation of the isolating contact. (Reference) Figure 1 Figures and Figure 2The first cylinder 5 and the second cylinder 6 are respectively located on both sides of the worktable 1. The extended end of the first cylinder 5 passes through the connecting hole 340 on the first abutment plate 3 and is fixedly connected to the second abutment plate 4. The extended end of the first cylinder 5 is fixedly connected to the second abutment plate 4 by a screw. The screw is locked to different depths, so that the length of the entire rod is different. When the first cylinder 5 is activated, it can drive the second abutment plate 4 to move horizontally above the worktable 1. The first cylinder 5 can be a single-acting cylinder, which has a simple structure and low cost; or it can be a double-acting cylinder, which can achieve bidirectional movement and has stronger power. The extended end of the second cylinder 6 passes through the connecting hole 340 on the second abutment plate 4 and is engaged with the long isolation pin shaft 15 by a snap-fit ​​block 601. The snap-fit ​​block 601 is cylindrical in the middle and rectangular blocks on both sides of the cylinder. This design can better secure the long isolation pin shaft 15 and ensure the accuracy of installation. The second cylinder 6 plays a key role in the installation of the long isolation pin shaft 15, and its movement accuracy directly affects the installation quality of the isolation contact. refer to Figure 5 Two first placement plates 7 are spaced apart, each with a prismatic groove 701 on its top for placing the two sides of the isolation crank arm 11. The shape of the prismatic groove 701 matches the end shape of the isolation crank arm 11, ensuring proper positioning. The first placement plates 7 are generally made of a metal material with moderate hardness and a smooth surface to ensure stable placement of the isolation crank arm 11. The second placement plate 8 is fixedly connected to the workbench 1 and has an arc-shaped groove 801 on its top for placing one side of the isolation insulating rod 14. The curvature of the arc-shaped groove 801 must be adapted to the outer diameter of the isolation insulating rod 14 to ensure a close fit. The first placement plates 7 and the second placement plates 8 are correspondingly arranged and located on both sides of the slide groove 101. A support plate a9 is provided between them, fixedly connected to the workbench 1, with an opening groove on its top for placing the other side of the isolation insulating rod 14. The support plate a9 enhances the overall structural strength of the equipment and provides stable support for the isolation insulating rod 14. Support plate b10 is used to support the isolation crank arm 11 and improve the stability of the isolation crank arm 11 during installation. Support plate b10 is fixedly connected to the workbench 1 and is spaced apart on one side of support plate a9. (Reference) Figure 1 and Figure 2Two isolation connecting plates 12 are spaced apart, one placed in the stepped groove b302 and the other in the mounting groove 403. The isolation slider 13 is placed in the stepped groove a301, the two sides of the isolation crank arm 11 are respectively placed in the prismatic groove 701, and the isolation insulating rod 14 is placed on one side in the arc groove 801 and the other side in the opening groove of the support plate a9. The isolation crank arm 11 is connected to one of the isolation connecting plates 12 via a short isolation pin shaft 15, and the isolation insulating rod 14 is connected to the isolation slider 13 via a long isolation pin shaft 15. When the first cylinder 5 retracts, the second abutment plate 4 moves horizontally on the worktable 1, which will fit the other isolation connecting plate 12, which is located in the mounting groove 403, onto the long and short isolation pin shafts 15, thereby completing the installation of the isolation contact. The implementation principle of this embodiment is that this isolation contact installation device overcomes many defects of traditional isolation contact installation methods through the reasonable arrangement and coordinated work of various components. Workbench 1 provides a stable operating platform. First and second supporting plates 3 and 4 position and fix the components. First and second cylinders 5 and 6 provide power, enabling automated installation. First placement plate 7, second placement plate 8, and support plate a9 effectively place and support each component, ensuring accuracy during installation. Once the isolating contacts are engaged, they detach from the installation equipment. The entire device has a compact structure, adaptable to the installation needs of different specifications of isolating contacts, greatly improving installation efficiency and accuracy, reducing manual intervention, lowering labor intensity, and increasing enterprise production efficiency. It represents a significant improvement over existing technology.
