[0002] In power facility maintenance, brick cable trench appears problems such as structure aging, silt accumulation in trench bottom due to service life increase, and needs to be reconstructed and upgraded. Traditional reconstruction needs power-off construction (cannot guarantee the safety of cable), which affects power supply.

[0003] Currently, in order not to affect power supply, a support device with a spacing of 1.5 meters is generally used to set a suspension point to support the cable with a spacing of 1.5 meters, so that the cable maintains a certain distance from the trench bottom and side wall, and the safety of the cable during construction is ensured. However, the traditional support device has obvious defects: in terms of height adjustment, the structure design is often fixed, and it is difficult to adapt to the actual conditions of different cable trenches. For example, the depth of some cable trenches differs due to different terrain and construction standards, and the depth may change due to settlement after long-term use. The traditional support device cannot flexibly adjust the support height, which affects the construction safety and quality and greatly limits its practicality. In terms of insulation performance, the traditional support device is made of ordinary materials, and the insulation effect is greatly reduced in complex environments such as long-term humidity and corrosive gases. Once the insulation performance fails, it is easy to cause safety accidents such as electric leakage, which threatens the safety of construction personnel and the stable operation of the power system. In terms of cable support method, the traditional device relies on manual cable binding, which is tedious and time-consuming.

[0004] Therefore, in order to solve the above technical problems, the present application provides an insulated suspension support device for cable trench reconstruction. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION

[0024] As Figures 1-5 shown, the utility model provides an insulating suspension support device for cable trench reconstruction, including the support 1 of symmetrical setting in the top of cable trench two side walls, the height of support 1 can be adjusted, and the head of support 1 is connected with insulating pipe 3 (polytetrafluoroethylene material is made) through dismounting assembly 2, and insulating pipe 3 is installed with tie -down assembly 4 that is adjusted tight and insulating through plug -in structure

[0025] During cable trench renovation construction, the supports 1, symmetrically installed on the top of both sides of the cable trench, are height-adjustable. This allows for flexible adjustment to accommodate depth differences caused by terrain, construction standards, and long-term settlement, providing a suitable suspension height for the cables. This avoids the drawbacks of fixed-height traditional support devices, ensuring construction safety and quality. The head of the supports 1 connects to the insulating tube 3 via the disassembly assembly 2, facilitating quick installation and removal of the insulating tube 3 as needed. The insulating tube 3 itself has excellent insulation properties, and the cable tie assembly 4 is also insulated. Even in complex environments with moisture and corrosive gases, this effectively prevents leakage accidents, ensuring the safety of construction personnel and the power system. When supporting the cables, the cable tie assembly 4 installed on the insulating tube 3 allows for easy adjustment and positioning of the tightness through its plug-in structure. Compared to traditional manual binding methods, this is simpler, more efficient, and saves construction time and labor costs.

[0026] The following is the specific structure of bracket 1: Bracket 1 includes a base 101, with a screw A102 fixedly connected to the center of the top of the base 101. A movable block 103 is sleeved on the outer wall of the screw A102. Guide rails 104 are fixedly connected to both sides of the top of the base 101 on the screw A102. The movable block 103 is slidably connected to the guide rails 104 on both sides via sliders 105. Nuts A106 are threadedly connected to the upper and lower sides of the movable block 103 on the outer wall of the screw A102. The head of the slider 105 is connected to the disassembly / assembly assembly 2 via a vertical rod 107.

[0027] Pull the movable block 103 up and down. The movable block 103 moves up and down along the screw A102. At the same time, the movable block 103 drives the slider 105 up and down. The slider 105 slides up and down along the guide rail 104 to maintain the linear up and down movement of the movable block 103. The slider 105 linearly drives the vertical rod 107 to move up and down linearly. The vertical rod 107 drives the disassembly and assembly component 2 to move up and down, so as to achieve the purpose of adjusting the insulating suspension support device. After the adjustment is completed, rotate the nuts A106 located on the upper and lower sides of the movable block 103.
