Description

Technical Field

[0001] The invention relates to the technical field of cable installation and construction, in particular to a multi-adjustable elastic electrical cable installation device and a cable construction and adjustment method thereof. Background Art

[0002] Antenna cables are a general term for optical cables, electrical cables, large-scale antennas and other wire items. There are many cables used in electrical automation systems and large-scale MIMO. During wiring construction, it is usually necessary to install different antennas at the same time, so an antenna installation device is needed.

[0003] At present, traditional single-function cable laying devices are commonly used in cable construction such as electrical automation and signal setting to lay different cables. However, the existing laying device has a simple structure and mainly relies on fixed rings and laying platforms to fix the cables. Since the fixed rings are of uniform size, they cannot adapt to cables of various sizes, which makes it difficult to fix some cables in the rings and makes them easy to slide, affecting the tensioning effect. In addition, it is not flexible to adjust the cable laying angle, and it is difficult for the cables to maintain a stable position between the fixed ring and the laying platform, which makes it easy for the cables to move between the fixed ring and the laying platform. In this case, the tensioning effect of the tensioning wheel is difficult to guarantee, and it is easy to cause the cables to be misaligned after laying. These problems affect the efficiency and accuracy of cable laying, increase the difficulty of construction, and reduce the quality of construction.

[0004] The existing Chinese patent with patent announcement number "CN218708192U" has announced an "electrical cable laying device", which can tension the cables during laying through a tensioning wheel, thereby improving the stability of the cables after laying, and solving the problem that the currently used cable laying equipment cannot tension the cables, and the cables are prone to fall and sway due to insufficient tension after laying. However, it still solves the problems of laying cables of different diameters, fine-tuning a single line up and down, and laying with an overall adjustable angle.

[0005] Therefore, based on the existing practical needs and based on further innovation of the above-mentioned erection structure, a multi-adjustable elastic antenna cable erection device and a cable construction and erection adjustment method are provided, which can clamp and fix antennas of different diameters, can be erected for multiple longitudinal adjustments, and can conveniently adjust the antenna erection angle. Summary of the invention

[0006] The present invention provides a multi-adjustable elastic electrical cable installation device and a cable installation adjustment method thereof to solve the problems raised in the above background technology.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A multi-adjustable elastic electrical cable laying device comprises a rotating base, a lifting bracket is movably installed above the rotating base, a support plate is installed above the lifting bracket, two rows of symmetrically arranged slide rails are provided on the support plate, and each of the slide rails is provided with a plurality of spring clamping structures, the spring clamping structure comprises a lower fixed wheel group slidably installed on the slide rail, an upper movable wheel group is provided on the top of the lower fixed wheel group, the upper movable wheel group is elastic upper and lower movable pressure wheels, and a movable self-adjusting pressure wheel clamping structure for different cables is formed between the upper movable wheel group and the lower fixed wheel group.

The two slide bars are lifted at the same time by the lifting handle to drive the movable wheel to move upward, which is convenient for the installation of electrical cables. The slider 2 moves vertically up and down with the slide bar in the through slot.

[0012] Preferably, a spring is wound around the outer circumference of each slide bar, and a support plate is connected to the opposite side of the two slide blocks, and a movable wheel is connected between the two opposite support plates. The slide bar is used to guide the vertical movement of the slide block 2, and at the same time acts as a limit spring to prevent the spring from twisting during the compression process.

[0013] Preferably, the maximum expansion length of the spring is greater than the height in the through slot. This ensures that the spring can press the slider 2 down to the bottom of the through slot and also provides pressure between the movable wheel and the fixed wheel to ensure the clamping and fixing stability of the electrical cable.

[0017] Preferably, the transverse plate is located between two rows of the spring clamping structures, forming an electrical cable fixing clamping structure in which both sides are clamped and the middle tensioning wheel moves up and down to tension.

[0018] A cable construction adjustment method based on the above-mentioned multi-adjustable elastic electrical cable installation device comprises the following steps:

[0019] 1) The sliding bar is driven upward by the lifting handle, and the sliding bar squeezes the spring to drive the second slider to move upward, thereby driving the movable wheel upward through the support plate, so that one end of the electrical cable passes through the fixed wheel, the tensioning wheel and the fixed wheel on the other side in sequence, and then the lifting handle is released, so that the movable wheel is reset under the drive of the spring, so that the movable wheel can fix the electrical cable with the cooperation of the fixed wheel. When installing electrical cables of different diameters, the movable wheel is adaptively fine-tuned up and down in the vertical direction through the elasticity of the spring. Both the fixed wheel and the movable wheel adopt an hourglass-shaped wheel body with large ends and a small middle. When the electrical cable is clamped, the electrical cable can be automatically gathered to the middle of the movable wheel and the fixed wheel to achieve left and right fine-tuning of the cable in the horizontal direction;

[0020] 2) By moving the position of the slider 1 on the slide rail, the horizontal and lateral position of the spring clamping structure and the clamped electrical cable is adjusted;

[0021] 3) The motor drives the rotating plate to rotate, the rotating plate drives the frame plate to rotate, and the frame plate drives the supporting plate to rotate, so that the installation angle of the electrical cable can be adjusted at multiple angles;

[0022] 4) The electric push rod 26 can drive the lifting plate 28 to move up and down, and the lifting plate 28 drives the cross plate 32 to move up and down through the support rod 30, thereby driving multiple sets of tensioning wheels 35 to move up and down within a large range of adjustment, and can realize tensioning of electrical cables.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] The multi-adjustable elastic electrical cable laying device of the present invention adopts the design of the upper movable wheel group and the lower fixed wheel group of the spring clamping structure and the hourglass-shaped wheel body structure, and utilizes the elastic force of the spring to adaptively adjust the spacing between the movable wheel and the fixed wheel, so as to adapt to cables of different diameters, and realize single fine adjustment of the upper and lower parts when the cables are laid, so as to realize single fine adjustment of the cables in the same row, and the built-in motor of the rotating base drives the rotating plate to realize 360° rotation adjustment, so as to facilitate the rapid adjustment of the cable laying direction and adapt to the angle requirements of complex construction scenes, and the lifting bracket drives the lifting plate and multiple sets of tensioning wheels to rise and fall synchronously through the electric push rod, so as to quickly adjust the cable tension, avoid cable relaxation or sagging, and realize large adjustment of the upper and lower laying; by moving the position of the slider one on the slide rail, the spring clamping structure and the clamped electrical cable are adjusted horizontally and transversely, and in addition, the hourglass-shaped wheel body structure can automatically gather the cables to the middle, improve the clamping stability, and avoid cable sliding or dislocation, and the lifting handle is linked with the double slide rod, so that the movable wheel can be lifted by one hand, which is convenient for the rapid insertion or removal of the cable, and the construction efficiency is significantly improved.

[0025] The cable construction and installation adjustment method based on the device quickly releases the movable wheel space by pulling the handle, and combines the synchronous adjustment of multiple sets of tensioning wheels to achieve one-time insertion, clamping and tensioning of the cable, reduce repeated adjustment steps, shorten construction time, and control the electric push rod and motor linkage to support real-time dynamic adjustment of height and angle, ensuring that the cable is always in the best tension state and preset path, reducing the frequency of manual intervention. Through the standardized operation steps of threading → clamping → tensioning → direction adjustment, human operation errors are reduced, ensuring that the cable installation position is accurate, neatly arranged and adjustable, and improving the overall construction quality.
