Description

Technical Field

[0001] This utility model belongs to the field of tooling equipment technology, specifically relating to a tooling for installing a trip spring. Background Technology

[0002] In circuit breakers, the tripping spring is a crucial component, typically housed within the operating mechanism box. In the assembly of load switches and load switch-fuse combination units, due to limited space, installation tools are often used to install the tripping spring. The tripping spring has a connecting part for attaching the installation tool, and this connecting part has mounting holes adapted to relevant components.

[0003] In existing technology, during the installation of the ZW32 trip spring, a simple tool is used to clamp the connecting part of the trip spring. Pulling the tool extends the trip spring and installs it onto the relevant components. During the pulling of the trip spring, the simple tool may detach, leading to installation failure. Furthermore, detachment of the simple tool can easily cause injury to the operator, posing a safety hazard. In addition, directly pulling the tool is labor-intensive, time-consuming, and impractical. Utility Model Content

[0004] This utility model provides a tooling for installing a trip spring, which aims to solve the problem of high labor intensity and safety hazards in the existing technology, where operators directly pull the simple tooling clamped on the trip spring to install it.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a tooling for installing a trip spring, comprising: The movable installation structure is set vertically and is plugged into the trip spring; A winding drum is located below the movable installation structure.

[0019] Please refer to the following: Figures 1 to 3 The tooling for installing a trip spring provided by this utility model will now be described. The tooling for installing the trip spring includes a movable mounting structure 10, a winding drum 20, and a drive-locking structure 30. The movable mounting structure 10 is arranged vertically and is plugged into the trip spring 60. The winding drum 20 is located below the movable mounting structure 10 and is rotatably mounted on the mounting base 50. A cable 40 is wound in the winding drum 20, and the free end of the cable 40 is connected to the bottom end of the movable mounting structure 10. The drive-locking structure 30 is mounted on the mounting base 50 and connected to the rotating shaft of the winding drum 20. It is used to drive the winding drum 20 to rotate, thereby pulling the cable 40 to drive the movable mounting structure 10 downwards and locking the movable mounting structure 10 in the vertical direction.

[0020] In this embodiment, the movable mounting structure 10 is plugged into and connected to the trip spring 60. A winding drum 20 is provided below the movable mounting structure 10, and a cable 40 is wound in the winding drum 20. The free end of the cable 40 is connected to the bottom end of the movable mounting structure 10. The winding drum 20 is rotatably mounted on the mounting base 50. The drive self-locking structure 30 is also mounted on the mounting base 50 and is connected to the rotating shaft of the winding drum 20. It is used to drive the winding drum 20 to rotate and pull the cable 40 to drive the movable mounting structure 10 downward. This eliminates the need for the operator to raise their hand to pull the tool to extend the trip spring 60, reducing labor intensity. Furthermore, the drive self-locking structure 30 can lock the movable mounting structure 10 in the vertical direction, facilitating the installation of the trip spring 60.

[0021] The fixture for installing the trip spring provided in this embodiment of the utility model, compared with the prior art, prevents the movable installation structure 10 from falling off the trip spring 60 during movement by connecting the movable installation structure 10 to the trip spring 60, thus enhancing safety. A winding drum 20 is provided below the movable installation structure 10, with a cable 40 wound inside. The free end of the cable 40 is connected to the bottom end of the movable installation structure 10, thereby moving the movable installation structure 10 vertically by winding and unwinding the cable 40. The winding drum 20 is mounted on a mounting base 50, which also has a self-locking drive structure 30 connected to the shaft of the winding drum 20, causing the winding drum 20 to rotate. By pulling the cable 40, the movable installation structure 10 moves downward, eliminating the need for operators to raise their hands to pull the fixture to extend the trip spring 60, reducing labor intensity and saving time and effort. Furthermore, the self-locking drive structure 30 can lock the vertical position of the movable installation structure 10, which facilitates the installation of the trip spring 60 and improves work efficiency.

[0022] It should be noted that during installation, the opening spring 60 needs to be extended first, so that it reaches the height of the relevant component in the vertical direction, before being installed onto the component. When the drive self-locking structure 30 drives the winding drum 20 to rotate, it pulls the cable 40 to drive the movable mounting structure 10 downward, thereby extending the opening spring 60. Then, the opening spring 60 is installed. During installation, the drive self-locking structure 30 locks the movable mounting structure 10 in the vertical position, so the operator does not need to pull the movable mounting structure 10 forcefully; they only need to install the opening spring 60 in place, reducing the operator's labor intensity.

[0023] In some embodiments, please refer to Figure 1 and Figure 2The movable mounting structure 10 includes a plug 11, an abutment plate 12, and a movable plate 13. The plug 11 is arranged horizontally and is plugged into the connecting part 61 of the opening spring 60. The abutment plate 12 is connected to the plug 11 and abuts against the connecting part 61. The abutment plate 12 has a through hole corresponding to the mounting hole of the opening spring 60. The upper end of the movable plate 13 is integrally connected to the abutment plate 12, and the lower end of the movable plate 13 is connected to the free end of the cable 40. In this embodiment, the plug 11 is provided on the abutment plate 12, the abutment plate 12 abuts against the connecting part 61, the upper end of the movable plate 13 is integrally connected to the abutment plate 12, and the lower end of the movable plate 13 is connected to the free end of the cable 40. Thus, the movable plate 13 is pulled vertically by the cable 40, and the plug 11 is plugged into the connecting part 61 of the opening spring 60, thereby stretching the opening spring 60. The plug 11 is set in the horizontal direction, and the opening spring 60 extends in the vertical direction, thereby ensuring the connection stability between the plug 11 and the opening spring 60 during the extension process of the opening spring 60.

[0024] It should be noted that the connecting part 61 is provided with a socket that is adapted to the insert post 11. The connecting part 61 cooperates with related components, and the connecting part 61 is provided with mounting holes that are adapted to related components. The abutment plate 12 is provided with through holes that correspond to the mounting holes, thereby ensuring smooth installation and ensuring installation efficiency.

[0025] In some embodiments, please refer to Figure 1 and Figure 3 The self-locking drive structure 30 includes an operating lever 31, a rotating gear 32, and a locking element 33. The operating lever 31 is connected to the rotating shaft and is used to drive the rotating shaft to rotate. The rotating gear 32 is mounted on the rotating shaft. The locking element 33 is rotatably mounted on the mounting base 50 and engages with the rotating gear 32 to limit the rotation of the rotating gear 32. In this embodiment, the operating lever 31 is connected to the rotating shaft to drive the rotating shaft to rotate.
