[0026] Example 1

[0027] Reference Figure 2, which is the first embodiment of the present invention, provides an auxiliary tool for preventing composite insulators from being stepped on. This device includes hooks, which are provided in two groups. The hooks are used to hang on the bottom line or cross-arm tower materials; and a connecting piece is used to connect the hooks and provide stable support.

[0028] Furthermore, the connecting piece includes an outer sleeve 201, a middle sleeve 202 and an inner sleeve 203. The outer sleeve 201, the middle sleeve 202 and the inner sleeve 203 are sequentially installed and can be telescopically adjusted in length. The connecting piece includes an inner sleeve 203 cross brace, a middle sleeve 202 cross brace and an outer sleeve 201 cross brace, which are respectively arranged between the two outer sleeves 201, the two middle sleeves 202 and the two inner sleeves 203 to play a supporting and stabilizing role. A joint 104 is installed at one end of the outer sleeve 201, and a hole is opened on the joint 104.

[0029] The outer sleeve 201 , the middle sleeve 202 and the inner sleeve 203 are all made of high-strength materials, and the material of the hanging operation rope 103 is a high-strength fiber material.

[0030] The device is designed to provide a safe and stable working platform for power line maintenance personnel, preventing damage and potential safety hazards caused by stepping directly on composite insulators. Specifically, the device includes two sets of hooks designed to be suspended from conductors or crossarm tower materials, ensuring that the device can be securely fixed near the work site. Each hook is designed to rotate 360 ​​degrees and lock closed, which not only adapts to different mounting angles but also prevents accidental slippage and other hazards during operation.

[0031] The connector connects the two sets of hooks and provides the necessary support stability. The connector consists of three parts: an outer sleeve 201, a middle sleeve 202 and an inner sleeve 203. These three parts are put together in sequence to form a structure that can be telescopically adjusted in length. This design allows staff to flexibly adjust the length of the device according to the actual working environment, so as to better adapt to various working scenarios. In addition, in order to enhance the overall stability and strength of the device, inner sleeve 203 cross braces, middle sleeve 202 cross braces and outer sleeve 201 cross braces are set between the two outer sleeves 201, the two middle sleeves 202 and the two inner sleeves 203. These cross braces can not only increase the connection strength between the tubes, but also effectively prevent deformation or damage caused by external forces during use.

[0032] One end of the outer sleeve 201 is fitted with a connector 104 with a hole for connecting a suspension rope 103, providing additional safety for the operator. When properly installed, these ropes provide stable support for the operator while standing or hanging, significantly reducing the risks of working at height.

[0033] In summary, this device, through its carefully designed hooks, connectors, and components, provides a practical and safe working platform for power line maintenance personnel. Its adjustable length and robust support structure ensure high flexibility and stability even in complex high-altitude working environments, effectively improving operational efficiency and safety.

[0034] Example 2

[0035] Reference Figures 1-2 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the hook includes a suspension rod 106, the suspension rod 106 is arranged at one end of the inner sleeve 203, and the ventilation triangular connecting plate 105 of the suspension rod 106 is connected to the inner sleeve 203.

[0036] Furthermore, the hook also includes a ground hook 108, which is set at one end of the boom 106, one end of the sealing door 107 is installed at one end of the ground hook 108, and the other end of the sealing door 107 is engaged with the other end of the ground hook 108.

[0037] Furthermore, the hook also includes a hanging operation rope 103, which passes through the hole on the joint 104 and is fixed to the joint 104. One end of the hanging operation rope 103 is fixedly connected to a safety buckle 102, which is used to ensure the safety of the clamping.

[0038] The hook further comprises a fixed anti-dropout protection hook 101 , which is fixedly connected to the safety buckle 102 , and the fixed anti-dropout protection hook 101 has two states: open and closed.

[0039] When in use, the hook portion of the device ensures safety and stability for workers working at height. Specifically, the hook comprises a boom 106, which is positioned at one end of the inner sleeve 203 and connected to the inner sleeve 203 via a triangular connecting plate 105. This design not only strengthens the connection between the boom 106 and the inner sleeve 203 but also provides additional stability, ensuring that it will not loosen or deform easily when bearing heavy weight.

[0040] One end of the boom 106 is equipped with a ground wire hook 108, a key safety component. Designed to rotate 360 ​​degrees and lock shut, it can be flexibly adapted to various mounting points, such as conductors or crossarm tower materials. A sealing door 107 is mounted on one end of the ground wire hook 108, which snaps into place with the other end of the ground wire hook 108. During use, the conductor rests on the U-shaped bottom end of the ground wire hook 108. This snap-on design ensures that the ground wire hook 108 will not accidentally open during use, thereby enhancing safety.

[0041] The hook also includes a hanging rope 103, which passes through a hole in the connector 104 and is fixedly connected to it. One end of the hanging rope 103 is fixedly connected to a safety buckle 102. The main function of the safety buckle 102 is to ensure the safety of the operator during the operation. The safety buckle 102 is usually designed with a locking mechanism to ensure that it will not be accidentally released during the operation, thus providing reliable protection for the operator.

[0042] Finally, the hook section is equipped with a fixed anti-slip protection hook 101, which is fixedly connected to the safety buckle 102. The fixed anti-slip protection hook 101 has two states: open and closed. When closed, it firmly secures to the tower material or conductor, preventing the operator from accidentally slipping and causing danger during operation. The open state allows the operator to quickly install and remove the device, improving work efficiency.

[0043] In summary, the hook portion of the device, through the ingenious combination of components such as the boom 106, ground wire hook 108, sealing door 107, hanging operation rope 103, safety buckle 102, and fixed anti-drop protection hook 101, provides a safe and reliable working platform for power line maintenance personnel. These components not only ensure the stability and safety of the device, but also greatly improve work efficiency and reduce the risks of high-altitude operations.

[0045] Reference Figures 1-2 , which is the third embodiment of the present invention.

[0046] The operating procedures of this device are: take the device out of the packaging and check whether all parts are intact.

[0047] According to the specific conditions of the work site, the lengths of the inner sleeve 203, the middle sleeve 202 and the outer sleeve 201 are adjusted to ensure that the device can adapt to the requirements of different heights and distances.

[0048] Rotate the ground wire hook 108 to an appropriate angle to ensure that it can be smoothly mounted on the conductor or cross arm tower material. Hang the ground wire hook 108 on the conductor and lock it with the sealing door 107 to ensure that the hook does not accidentally slip off.

[0049] Install the fixed anti-slip protection hook 101 at one end of the hanging operation rope 103 and ensure it is in the closed state to prevent accidental slipping during operation. Check all connection points and fixing points to ensure that the entire device is stable and reliable.

[0050] Workers sit on the connector to reach the conductor position to perform work, preventing people from stepping on the synthetic insulator and causing damage to the insulator.

[0051] After the operation is completed, first open the fixed anti-drop protection hook 101 and remove the hanging operation rope 103. Unlock the ground hook 108 and remove the ground hook 108 from the wire. Retract the device, check whether all parts are damaged, and keep it properly for next use.
