Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, and in particular to a live insulating protective sleeve installation device. Background Technology

[0002] Insulating protective sleeves are sleeves made of insulating material used to protect wires, cables, or pipes, primarily for electrical insulation and mechanical protection. The insulating protective sleeves feature a lock-lock design (e.g., Figure 1 As shown in the figure, after installation, the edges and openings of the protective sleeve must be completely fastened to achieve the purpose of insulation. It is generally used in the modification of local electrical insulation, such as at the break or fracture.

[0003] 10kV lines operate outdoors year-round, and due to natural wear and tear, weathering, or other reasons, line faults can occur, seriously affecting the operational safety of the lines. During the insulation upgrade of 10kV lines, specialized insulation tools and equipment must be used, and the work must be carried out by professionally trained personnel under strict safety measures.

[0004] Most insulating protective bushings are designed to be installed when the power line is de-energized, which significantly impacts the reliability of the power distribution network. Therefore, in actual installation, it is generally a live-line operation, requiring the use of specialized equipment such as insulated work vehicles, and workers must wear insulated clothing before installation can proceed.

[0005] In addition, due to limitations such as the terrain during the installation process, the insulation work vehicle cannot reach the site, making it impossible to carry out local live insulation modifications; moreover, since it is a 10KV line, workers cannot climb onto the cable to carry out insulation modifications.

[0006] Therefore, research on live-line installation tools for relevant insulating protective sleeves, especially indirect installation tools, is of great practical significance for improving the reliability of power distribution networks and operational safety. Utility Model Content

[0007] The technical problem to be solved by this utility model is: in order to solve the problems existing in the prior art mentioned above, to provide a live insulating protective sleeve installation device that is simple in structure, easy to use, improves installation efficiency and safety factor, and ensures the stable operation of the power grid.

[0008] The technical solution adopted by this utility model to solve its technical problem is: a live insulating protective sleeve installation device, including an installation head and a linker, wherein the installation head is installed on the linker;

[0009] The mounting head includes a mounting frame and elastic elements. The mounting frame has an open receiving cavity, and a plurality of elastic elements are mounted on the bottom surface of the receiving cavity. An insulating protective sleeve is placed on the elastic elements.

[0010] Both sides of the mounting frame opening have inwardly bent sections at their edges, forming slots. The two flanges of the insulating protective sleeve opening are respectively secured in the slots.

[0011] Link stick fasteners are installed at one side opening of the mounting frame, and the link sticks are mounted on the mounting frame through the link stick fasteners.

[0012] Furthermore, the elastic element is a spring or elastic band.

[0013] Furthermore, the spring is a conical spring, with the small end of the spring mounted on the base plate of the mounting frame.

[0014] Furthermore, the bottom plate of the mounting frame is stamped with several stamped parts to lock the elastic element. Each stamped part is composed of several stamped tongues arranged in a circular array. The stamped tongues form a placement area for the elastic element, and the stamped tongues bend inward to lock the elastic element.

[0015] Furthermore, several locking holes for installing elastic elements are provided on the two side plates of the mounting frame.

[0016] Furthermore, the included angle α between the bent portion and the side plate of the mounting frame is 20° to 30°.

[0017] Furthermore, the height of the mounting frame is greater than the sum of the height of the compressed elastic element and the height of the insulating protective sleeve.

[0018] Furthermore, several weight-reducing holes are provided at the openings on both sides of the mounting frame.

[0019] Furthermore, the linker fastener includes a mounting block and a linker fixing block. The mounting block is mounted on the side plate of any mounting frame. The mounting block has a protrusion that protrudes above the side plate of the mounting frame. The linker fixing block is mounted on the protrusion. The linker fixing block has a first mounting notch. The protrusion has a second mounting notch that is flush with the inner wall of the first mounting notch.

[0020] The link bar includes a shaft and a connector. The connector is mounted on the shaft, and the connector has several connector teeth on its connecting surface.

[0021] The connecting surface of the link bar fixing block has several fixing teeth that mate with the teeth of the connecting head.

[0022] A method of using a live insulating protective sleeve installation device, comprising the live insulating protective sleeve installation device as described in any of the above claims, including the following steps:

[0023] Step 1: First, the operator selects the length of the installation head according to the required length of the insulating protective sleeve in the work area. Then, the operator places the insulating protective sleeve on the elastic element, which supports the insulating protective sleeve. Finally, the operator inserts the two flanges at the opening of the insulating protective sleeve into the slots to complete the installation of the insulating protective sleeve. At this time, the opening of the insulating protective sleeve is in the open state.

[0024] Step 2: Select a link bar of appropriate length and install it on the link bar fixing piece. At this time, the opening of the mounting head should face downwards to complete the installation of the mounting device.

[0025] Step 3: The operator lifts the installation device after Step 2 and moves it to the work area. The installation head is placed over the cable in the work area from top to bottom. Then, the operator pulls down the link bar to compress the elastic element. The two flanges of the insulating protective sleeve slide out of the slot and the insulating protective sleeve closes automatically, thus covering the cable in the work area.

[0038] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0039] Example 1:

[0040] like Figures 2-8 The illustrated device for installing an electrically insulating protective sleeve includes an installation head 1 and a linker 2, wherein the installation head 1 is installed on the linker 2.

[0041] The mounting head 1 includes a mounting frame 11 and elastic elements 12. The mounting frame 11 has an open receiving cavity. Several elastic elements 12 are mounted on the bottom surface of the receiving cavity. An insulating protective sleeve is placed on the elastic elements 12. The elastic elements 12 are springs.

[0042] In addition, the length of the mounting frame 11 is selected according to the length of the work area. The two side plates at the opening of the mounting frame 11 are provided with inwardly bent parts 13 to form a slot. The two side flanges at the opening of the insulating protective sleeve are respectively locked in the slot.

[0043] Linker fastener is installed at one side opening of mounting frame 11, and linker 2 is installed on mounting frame 11 through linker fastener.

[0044] The mounting frame 11 includes two side plates and a bottom plate. The two side plates, the bottom plate, and the bending part 13 are formed by bending a single piece of steel plate.

[0045] Among them, such as Figure 5As shown, the spring is a conical spring. The application of conical springs helps to distribute the stress of the spring more evenly, reduce local stress concentration, adapt to different loads, provide more consistent performance, help reduce friction and wear of the spring during movement, the large end can provide a larger contact area, increase the stability and reliability of the spring in the application, enable it to provide the required elastic force in a limited space, provide better vibration absorption performance, and adjust the energy storage and release of the spring as needed. The small end of the spring is mounted on the base plate of the mounting frame 11.

[0046] like Figure 4 As shown, the base plate of the mounting frame 11 has several stamped parts stamped on it to lock the elastic element 12. Each stamped part is composed of several stamped tongues 14 arranged in a circular array. The stamped tongues 14 form a placement area for the elastic element 12, and the stamped tongues 14 bend inward to lock the elastic element 12. The stamped tongues 14 reduce the overall weight of the mounting frame 11 by partially removing material, and lock the elastic element 12 without adding any parts, further reducing the overall weight of the mounting frame 11.

[0047] like Figure 5 As shown, the included angle α between the bent part 13 and the side plate of the mounting frame 11 is 20° to 30°. The width of the bent part 13 is slightly smaller than the width of the flange of the insulating protective sleeve. When the elastic element 12 is subjected to downward tension, it is easy for the two flanges of the insulating protective sleeve to quickly disengage from the slot. At the same time, when in the installation state, the insulating protective sleeve will not slip out of the slot under its own elastic force.

[0048] The height of the mounting frame 11 is greater than the sum of the height of the compressed elastic element 12 and the height of the insulating protective sleeve.

[0049] like Figure 3 As shown, several weight-reducing holes 15 are provided at the openings on both sides of the mounting frame 11. While ensuring the strength of the mounting frame 11, the weight of the mounting frame 11 is reduced, thereby reducing the workload of the operators.

[0050] like Figure 6 As shown, the linker fastener includes a mounting block 24 and a linker fixing block 25. The mounting block 24 is mounted on the side plate of any mounting frame 11. The mounting block 24 has a protrusion 26 that protrudes from the side plate of the mounting frame 11. The linker fixing block 25 is mounted on the protrusion 26. The linker fixing block 25 has a first mounting notch 28. The protrusion 26 has a second mounting notch 29 that is flush with the inner wall of the first mounting notch 28.

[0051] like Figure 7As shown, the link bar 2 includes a rod body 21 and a connector 22. The connector 22 is installed on the rod body 21. The connector 22 has a plurality of connector teeth 23 on its connecting surface. The rod body 21 can be a telescopic rod as needed.

[0052] The connecting surface of the link bar fixing block 25 is provided with several fixing block teeth 27 that cooperate with the connecting head teeth 23.

[0053] Work process:

[0054] Step 1: First, the operator selects the length of the installation head 1 according to the required length of the insulating protective sleeve in the work area. Then, the operator places the insulating protective sleeve on the elastic element 12, which supports the insulating protective sleeve. Finally, the operator inserts the two flanges at the opening of the insulating protective sleeve into the slots to complete the installation of the insulating protective sleeve. At this time, the opening of the insulating protective sleeve is in the open state.

[0055] Step 2: Select a link bar 2 of appropriate length and install the link bar 2 on the link bar fixing piece. At this time, the opening of the mounting head 1 should face downwards to complete the installation of the mounting device.

[0056] Step 3: The operator lifts the installation device after Step 2 and moves it to the work area. The installation head 1 is placed over the cable in the work area from top to bottom. Then, the operator pulls down the link 2 to compress the elastic element 12. The two flanges of the insulating protective sleeve slide out of the slot and the insulating protective sleeve closes automatically, thus covering the cable in the work area, completing the modification of partial live cable insulation. Finally, the operator lifts away the installation device.

[0057] Example 2:

[0058] The difference from Embodiment 1 is that the elastic element 12 is an elastic band. Several locking holes 16 for mounting the elastic element 12 are provided on both sides of the mounting frame 11.

[0059] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
