Description

Technical Field

[0001] The invention relates to the field of cable construction devices, and in particular to a secondary cable construction anti-stuck fixing device. Background Art

[0002] Secondary cables are used for control, signal transmission and feedback. In power systems and various electrical equipment, secondary cables are mainly responsible for transmitting various measurement, control, protection, communication and other signals between different devices or circuits. They are widely used in substations, power plants, industrial enterprises, rail transit and other places.

[0003] At present, the laying methods of secondary cables mainly include cable tray laying, cable trench laying, pipe laying and direct burial laying. Before laying, some cables need to be placed on a pay-off rack. During laying, the secondary cables are pulled from the predetermined starting position to the predetermined end position.

[0004] However, there are some problems in the laying of existing secondary cables as follows: 1. Some secondary cables usually need to pass through multiple corners during laying. When pulling the secondary cables, they are prone to getting stuck at the corners when passing through multiple corners, which not only affects the smoothness and stability of the cables during the corner dragging process, but also affects the laying efficiency.

[0005] 2. When laying some cables, guide wheels are used for guidance at corners. Such guide wheels are usually fixed at predetermined positions in specific laying sites using expansion bolts. Although they can play a certain steering and guiding role, they have special requirements such as being limited to cable trenches and being inconvenient to move.

[0006] 3. When laying cables of different thicknesses or with different turning angles, traditional technologies usually use guide wheel devices with adjustable spacing or angles to clamp and guide the cables. When in use, the spacing and angles between the guide wheels are adjusted by rotating the adjusting screws. Although it can play the role of laying, clamping and guiding cables of some different thicknesses or with different turning angles, there are still many components and the structure is relatively complex. In particular, after long-term and repeated rotation of components such as screws, wear, damage or jamming will occur. When these situations occur, maintenance personnel are required to eliminate the fault points and replace them, which not only wastes manpower and time, but also affects normal wiring construction and reduces wiring efficiency.

[0007] 4. When some existing cables are being laid, cable racks are used to support the cables. Traditional cable racks of this type, especially some larger cable racks, are usually set up separately. Although they can play a certain supporting role, in actual use, cables far away from the cable racks usually drag on the ground. When the cables are being laid, they will repeatedly rub against the ground, which can easily cause wear on the cable surface and even damage the cables. This will not only cause waste, but also affect the efficiency of cable laying. Summary of the invention

[0008] The purpose of the present invention is to provide a secondary cable construction anti-stuck fixing device to address the above-mentioned deficiencies, so as to solve the problems that the existing secondary cables are prone to getting stuck at corners when passing through multiple corners during laying, which easily affects the smooth dragging of the cables during the corner turning process, the instability of equipment support, and the reduction of laying construction efficiency.

[0061] Before use, ensure that all parts are complete, including the support and adjustment mechanism 1, the line towing mechanism 2 and the corner mechanism 3, and assemble the corresponding parts correctly to ensure that all connecting parts are tightened to ensure safety; during use, pass the cable through the line towing mechanism 2 and the line towing guide wheel 202 and the corner guide wheel 302 on the corner mechanism 3, and adjust the height and plane position through the support and adjustment mechanism 1 as needed. When performing the corner operation through the corner mechanism 3, the adjustment process should be pulled smoothly to avoid sudden force that may cause damage to the components.

[0062] During use, the lubrication condition of the deep groove ball bearing should be checked regularly, and lubricating oil should be added when necessary. Cleaning and maintenance should be done with a dry cloth to prevent moisture from entering the interior of the mechanism and keep the mechanism clean. Use it indoors as much as possible to avoid exposure to bad weather and overload to prevent damage to the mechanism. During operation of the device, all personnel should avoid contact with moving parts. Check whether the corner guide wheel 302 and the towing guide wheel 202 are blocked by foreign objects, and clean them in time to ensure smooth passage of the cables. Check all connection parts regularly to ensure that all screws and pins are tightened.

[0063] The present invention has obtained good feedback after trial use, and the support adjustment mechanism can realize precise adjustment of the cable height and the unfolding size, thereby ensuring the stability and safety of the cable in different application environments; the cable can be smoothly turned by setting a turning mechanism, and the turning angle can realize different turning angles through the customized production of corresponding components, thereby realizing the smooth passage of the cable at the turning angle of the predetermined angle; the cable towing mechanism ensures the stability of the cable when adjusting the height and pulling, effectively reduces the friction, and further ensures that the cable passes smoothly; the cable passes between the two towing guide wheels, which can realize the clamping and support of the cable.
