Description

Technical Field

[0001] This utility model relates to the technical field of insulator production equipment, specifically to a shim-inserting tool and its shim-inserting structure for hollow post insulators. Background Technology

[0002] With the application and development of ultra-high voltage power transmission and transformation projects in my country and the continuous improvement of voltage levels, power equipment is moving towards larger size and heavier tonnage. Insulator products are indispensable in the power system, especially post insulators, which are subject to increasingly higher electrical and mechanical performance requirements. This has prompted the development of larger-specification post insulators, among which hollow post insulators are being used more and more frequently in the power system.

[0003] Compared with conventional post insulators, hollow post insulators have a through-hole design, which gives them a significant advantage in terms of weight. Furthermore, the hollow part can be used to install related equipment and carry out wiring.

[0004] In the conventional production method of hollow post insulators, the sheath and skirt are integrally injection molded, which requires a large investment in injection molding machines and molds, resulting in high costs. Therefore, it is necessary to be more cautious in the early research and development stage. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the above-mentioned background technology and provide a tooling and structure for inserting umbrellas into hollow post insulators that can achieve the umbrella insertion operation without the need for a sheath and skirt integral injection molding, thereby effectively reducing the production cost of hollow post insulators.

[0006] To achieve this objective, the hollow post insulator shed fitting designed in this utility model includes a fitting sleeve with one end coaxially fitted onto the sheath of the hollow post insulator and axially movable relative to the sheath. One or more sheds can be coaxially fitted onto the fitting sleeve, and the one or more sheds can axially move on the surface of the fitting sleeve or move from the fitting sleeve to the sheath. One end of the fitting sleeve is provided with a guide structure that cooperates with the sheath, allowing one end of the fitting sleeve to be smoothly fitted onto the sheath.

[0007] Furthermore, the guide structure includes notches spaced apart on the circumferential surface of one end of the tooling sleeve.

[0008] Furthermore, the notch includes a first notch segment extending from one end face of the tooling sleeve along an axial direction parallel to the tooling sleeve to the other end of the tooling sleeve; through the first notch segment, one end of the tooling sleeve can be radially opened under the action of external force, increasing the radial dimension of one end of the tooling sleeve and allowing one end of the tooling sleeve to be smoothly fitted onto the protective sleeve.

[0009] Furthermore, the first gap segment is an elongated gap segment.

[0010] Furthermore, the notch also includes a second notch segment connected to one end of the first notch segment located inside the tooling sleeve, used to reset the first notch segment after it is opened, and to prevent irreversible deformation of the first notch segment after it is opened.

[0011] Furthermore, the second notch segment is an arc-shaped notch that connects with the first notch segment.

[0012] Furthermore, an operating part is fixedly connected to the other end of the tooling sleeve, which allows for convenient manual placement of the tooling sleeve onto the protective sleeve or removal of the tooling sleeve from the protective sleeve.

[0013] Furthermore, the operating part includes an operating ring coaxially fixedly connected to the other end face of the tooling sleeve.

[0014] Furthermore, a shed-insulating structure for a hollow post insulator using the aforementioned shed-insulating fixture includes a hollow post insulator and a sheath coaxially sleeved on the hollow post insulator, characterized in that: one or more shed skirts are coaxially sleeved on the fixture sleeve, and one end of the fixture sleeve is coaxially sleeved on the sheath through the guide structure.

[0015] Furthermore, the surface of the sheath is coated with an adhesive at the locations where the umbrella skirt needs to be secured.

[0016] The beneficial effects of this utility model are as follows: This utility model uses a tooling sleeve as the main body of the umbrella-installing tooling. The guide structure set at one end of the tooling sleeve allows it to be radially expanded under external force, increasing the radial dimension, thus enabling it to be smoothly fitted onto the sheath of the hollow post insulator. Furthermore, the second notch section allows the first notch section to return to its original position after being expanded, avoiding irreversible deformation and ensuring that the tooling sleeve can be reused multiple times. This facilitates quick and easy installation with the sheath during umbrella-installing operations. An operating part is fixedly connected to the other end of the tooling sleeve, facilitating manual operation. Whether fitting the tooling sleeve onto the sheath or subsequently removing it, it is much easier and more convenient, improving the overall ease of use of the umbrella-installing tooling. One or more sheds can be coaxially fitted onto the tooling sleeve, and the sheds can move axially on the surface of the tooling sleeve or move from the tooling sleeve to the sheath. This greatly facilitates the shed installation operation of hollow post insulators, making the adjustment of the shed installation position more flexible and accurate, facilitating precise shed installation, and improving the efficiency and quality of the shed installation operation. For the shed installation structure of hollow post insulators using this shed installation tooling, the sheath surface is coated with adhesive at the positions where the sheds need to be fixed, which can effectively stabilize the sheds on the sheath. The adhesive only serves a fixing function and does not need to lubricate the sheds during installation, reducing the amount of adhesive used. At the same time, it ensures the firmness of the sheds after installation, so that the sheds will not easily loosen or shift during subsequent use of the hollow post insulator, ensuring that it can perform its insulation and other related functions normally.

[0017] In summary, the umbrella-inserting fixture and structure designed in this utility model have demonstrated beneficial effects in terms of installation operation, umbrella skirt installation and adjustment, and fixing effect, which helps to achieve efficient and high-quality umbrella-inserting operation and subsequent stable use of hollow post insulators.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] like Figure 1 As shown in Figure 4, in some embodiments, the hollow post insulator shed fitting tool designed by this utility model includes a tool sleeve 1 that can be coaxially fitted onto the sheath 5 of the hollow post insulator 4 at one end and can move axially relative to the sheath 5. One or more shed skirts 6 can be coaxially fitted onto the tool sleeve 1. One or more shed skirts 6 can move axially on the surface of the tool sleeve 1 or move from the tool sleeve 1 to the sheath 5. One end of the tool sleeve 1 is provided with a guide structure that cooperates with the sheath 5 and allows one end of the tool sleeve 1 to be smoothly fitted onto the sheath 5.

[0025] Example 1:

[0026] Another type of hollow post insulator for the present invention has an overall structure that is basically the same as some of the above embodiments, except that the guide structure has been further optimized: the guide structure includes notches 2 that are spaced apart on the circumferential surface of one end of the tool sleeve 1.

[0027] Example 2

[0028] Another type of hollow post insulator for the present invention has a similar overall structure to some of the embodiments described above, except that the structure of the notch 2 has been further optimized: the notch 2 includes a first notch segment 2.1 extending from one end face of the tool sleeve 1 along the axial direction parallel to the tool sleeve 1 to the other end of the tool sleeve 1, and a second notch segment 2.2 connected to the end of the first notch segment 2.1 located inside the tool sleeve 1, used to reset the first notch segment 2.1 after it is opened, and to prevent irreversible deformation after the first notch segment 2.1 is opened; through the first notch segment 2.1, one end of the tool sleeve 1 can be radially opened under the action of external force, increasing the radial dimension of one end of the tool sleeve 1, and allowing one end of the tool sleeve 1 to be smoothly fitted onto the sheath 5.

[0029] Example 3

[0030] Based on Embodiment 2, this utility model provides a specific embodiment of the first notch segment 2.1: the first notch segment 2.1 is an elongated notch segment.

[0031] Example 4

[0032] Based on Embodiment 2, this utility model provides a specific embodiment of the second notch 2.2: the second notch segment 2.2 is an arc-shaped notch that communicates with the first notch segment 2.1.

[0033] Example 5

[0034] Another type of hollow post insulator for the present invention has a similar overall structure to some of the above embodiments, or Embodiment 1, Embodiment 2, Embodiment 3, or Embodiment 4, except that the other end of the tool sleeve 1 is fixedly connected to an operating part, which allows for easy manual placement of the tool sleeve 1 onto the sheath 5 or removal of the tool sleeve 1 from the sheath 5.

[0035] Example 6

[0036] Based on the above embodiment five, this utility model provides a specific embodiment of the operating part: the operating part includes an operating ring 3 that is coaxially fixedly connected to the other end face of the tooling sleeve 1.

[0037] Example 7

[0038] like Figure 3 As shown in Figure 4, a hollow post insulator shed-insulating structure using a shed-insulating fixture for hollow post insulators, employing some of the above embodiments, or Embodiment 1, Embodiment 2, Embodiment 3, Embodiment 4, Embodiment 5, or Embodiment 6, includes a hollow post insulator 4 and a sheath 5 coaxially sleeved on the hollow post insulator 4. One or more shed skirts 6 are coaxially sleeved on the fixture sleeve 1, and one end of the fixture sleeve 1 is coaxially sleeved on the sheath 5 through a guide structure. The surface of the sheath 5 is coated with adhesive at the positions where the shed skirts 6 need to be fixed.

[0039] In this utility model, the method of using the umbrella-threading fixture to perform the umbrella-threading operation on the hollow post insulator is as follows: the umbrella skirts 6 to be fitted are sequentially placed on the fixture sleeve 1, and then the umbrella skirts 6 and the fixture sleeve 1 are threaded together onto the hollow post insulator 4 covered by the sheath 5. After applying adhesive to the position on the sheath 5 where the umbrella skirts 6 need to be fixed, the umbrella skirts 6 are peeled off from the fixture sleeve 1. Finally, the umbrella skirts 6 are rotated to adjust the spacing between the upper and lower umbrella skirts 6.

[0040] A typical hollow post insulator 4 is about five meters high. Slipping a single skirt 6 down from the end of the insulator is a long and time-consuming process. Applying a large amount of adhesive to ensure smooth insertion is also wasteful. The skirt-slipping fixture designed in this invention saves a significant amount of time and distance. It eliminates the need to slip a single skirt 6 down from the end of the hollow post insulator 4; adhesive is simply applied to the fixed position of the skirt 6 on the sheath 5, effectively reducing adhesive usage. The fixture has a simple structure, is easy to operate, and effectively reduces the labor intensity of the operator. The umbrella skirt 6 is supported by the tooling sleeve 1. The flange face (operating ring 3) at one end of the tooling sleeve 1 is used for orientation and convenient manual operation. The other end has a number of notches 2 parallel to the axis of the tooling sleeve 1 for operation guidance. When the tooling sleeve 1 is moved axially to make the tooling sleeve 1 cooperate with the protective sleeve 5, the notches 2 will open radially due to external force. One end of the tooling sleeve 1 is fitted onto the protective sleeve 5 and is positioned with the protective sleeve 5. At this time, the umbrella skirt 6 can be rotated and moved to move the umbrella skirt from the tooling sleeve 1 to the protective sleeve 5, which greatly increases the installation convenience of the umbrella skirt 6.

[0041] This utility model uses a tooling sleeve 1 as the main body of the umbrella-installing tool. A guide structure at one end of the tooling sleeve 1 allows it to expand radially under external force, increasing its radial dimension and enabling it to be smoothly fitted onto the sheath 5 of the hollow post insulator 4. Furthermore, the second notch section 2.2 allows the first notch section 2.1 to return to its original position after expansion, preventing irreversible deformation and ensuring the tooling sleeve 1 can be reused multiple times. This facilitates quick and easy installation with the sheath 5 during umbrella installation. An operating part is fixedly connected to the other end of the tooling sleeve 1, facilitating manual operation. Whether fitting the tooling sleeve 1 onto the sheath 5 or subsequently removing it, the process is much easier, improving the overall convenience of using the umbrella-installing tool. One or more sheds 6 can be coaxially fitted onto the tooling sleeve 1, and the sheds 6 can move axially on the surface of the tooling sleeve 1 or move from the tooling sleeve 1 to the sheath 5. This greatly facilitates the shed installation operation of hollow post insulators, making the installation position adjustment of the sheds 6 more flexible and accurate, facilitating precise shed installation, and improving the efficiency and quality of the shed installation operation. For the shed installation structure of the hollow post insulator 4 using this shed installation tooling, the surface of the sheath 5 is coated with adhesive at the positions where the sheds 6 need to be fixed, which can effectively stabilize the sheds 6 on the sheath 5. The adhesive only serves a fixing function and does not need to lubricate the sheds 6 during installation, reducing the amount of adhesive used. At the same time, it ensures the firmness of the sheds 6 after installation, so that the sheds 6 will not easily loosen or shift during subsequent use of the hollow post insulator 4, ensuring that it can perform its insulation and other related functions normally.

[0042] In summary, the umbrella-inserting fixture and structure designed in this utility model have demonstrated beneficial effects in terms of installation operation, umbrella skirt installation and adjustment, and fixing effect, which helps to achieve efficient and high-quality umbrella-inserting operation and subsequent stable use of hollow post insulators.
