Description

Technical Field

[0001] This invention relates to the field of cable laying, and more specifically, to a radial leaky cable laying device with a protective device. Background Technology

[0002] With the rapid development of my country's national economy, major provincial capitals across the country are vigorously developing and constructing urban rail transit. This rapid development has placed higher demands on wireless communication systems for various applications. Urban rail transit wireless communication systems are divided into dedicated wireless communication systems and public wireless communication systems. Dedicated wireless communication systems include wireless dispatching communication systems, train control information car-to-ground wireless transmission systems, mobile television systems, public security wireless communication systems, fire-fighting wireless emergency communication systems, and passenger guidance information systems. Public wireless communication systems include 2G, 3G, Wi-Fi, and 4G wireless signals from China Mobile, China Unicom, and China Telecom. The propagation characteristics of radio waves in tunnels differ from their free-space propagation characteristics on the ground in urban rail transit wireless communication systems. Currently, all wireless communication systems in urban rail transit use leaky coaxial cables for wireless signal coverage. At least four leaky coaxial cables need to be laid in each of the up and down tunnel sections. When laying down cables, a special cable laying device is often required to assist in the cable laying process. However, the device has poor guidance during operation and the cable is prone to bending. Therefore, when fixing and clamping the cable, it is necessary to adjust the position of the cable, which is quite cumbersome. To address this issue, a cable laying device with better guidance is proposed. Summary of the Invention

[0022] Furthermore, in the above scheme, multiple fixed wheels 2 are provided and correspondingly arranged at the four corners of the lower end of the base plate body 1, which facilitates continuous cable laying. Two of each of the first support block 3, concave adapter groove 4, rotating support rod 20, second support block 17, telescopic motor 18, and control connecting rod 19 are provided and correspondingly arranged on both sides of the transverse central axis in the top view direction of the base plate body 1, which facilitates the support and fixation of the cable rollers 6.

[0025] Working principle of this invention:

[0026] When this invention is in operation, the device is moved to the upper end of the track, and then the telescopic motor 18 is controlled to extend upward. With the telescopic motor 18 and the control connecting rod 19 correspondingly connected to the rotating support rod 20, the rotating support rod 20 will rotate, thereby adjusting the position of the concave adapter groove 4 at the upper end of the rotating support rod 20. After adjusting the position of the concave adapter groove 4 to a suitable angle, the cable roller 6 is placed on one side of the base plate body 1, and then the concave adapter groove 4 is inserted into the middle of the cable roller 6. The cable roller 6 is then rolled to move it to the inside of the rotating support rod 20, placing the concave adapter groove 4 inside. Then, the telescopic motor 18 is started to control its inward retraction. The telescopic motor 18 drives the rotating support rod 20 to rotate. The concave adapter groove 4 gradually lifts the cable roller 6 off the ground until the rotating support rod 20 is perpendicular to the base plate body 1. Then, one end of the cable is passed through the inside of the limiting support rod 11, then through the top of the first inclined support rod 8, and then through the bottom of the second inclined support rod 14. Then, the base plate body 1 can be pulled forward by external equipment. The cable will pass through the inside of the limiting support rod 11, the top of the first inclined support rod 8, and the bottom of the second inclined support rod 14 in sequence and be laid on the ground. When the cable is moved and laid on both sides of the cable roller 6, the circular sliding piece 7 will rotate to a suitable angle to facilitate the guidance of the cable.
