Digital railway trackside safety communication equipment mainly includes a series of equipment that uses modern information technology to achieve high-speed and reliable data exchange between trains and the ground. These devices are crucial to ensuring train operation safety, improving transportation efficiency, and realizing intelligent management. The following are some major categories of digital railway trackside safety communication equipment: wireless communication equipment, train control system interface equipment: intelligent sensors and monitoring systems, and data communication network equipment.

[0003] Publication No. CN222116810U discloses a digital railway trackside safety communication device, which can improve the installation efficiency of signal transmission equipment and realize rapid installation of signal transmission equipment. By providing a sleeve rod and an adjustment rod, the signal transmission equipment is slidably connected to one end of the sleeve rod at the same time, so that the height of the signal transmission equipment can be adjusted by adjusting the height of the sleeve rod, thereby improving the efficiency of height adjustment during installation of the signal transmission equipment and thus improving the installation efficiency of the signal transmission equipment. By providing a first friction tooth and a second friction tooth on the outer wall of the adjustment rod and the inner wall of the sleeve rod respectively, the first friction tooth and the second friction tooth are staggered so that the signal transmission equipment can be temporarily maintained at a suitable height after being adjusted to a suitable height, facilitating the installation of a limit nut and a connecting screw, thereby improving installation efficiency. However, this patent still has the following problems in actual use: Although the digital railway trackside safety communication device can realize the rapid installation of signal transmission equipment, in railway transportation, channel signal enhancement equipment is needed to improve the railway's wireless communication signal, especially in tunnels. Since the signal inside the tunnel is weak, it is necessary to use signal enhancement equipment to improve the wireless communication signal. However, the signal is affected by the installation position, direction and angle. The angle cannot be changed at any angle in the tunnel, which affects the signal enhancement effect of the signal enhancement equipment. At the same time, when the train passes, an airflow field will be generated, thereby generating a certain suction force, which will cause the signal enhancement equipment to be sucked toward the train, thereby causing damage to the signal enhancement equipment.

After the signal enhancer is installed, the position of the signal enhancer can be adjusted according to changes in the environment. Since the signal of the signal enhancer is affected by environmental factors, it is necessary to adjust the signal enhancer to the position with the best signal according to changes in the environment, thereby improving the strength of the wireless communication signal. When a train passes, an airflow field is generated, thereby generating a certain suction force, which will cause the signal enhancer to be sucked toward the train. By providing a protective arc plate and a closing block, the protective arc plate and the closing block can be retracted through the protective rotating rod and the protective spring when the suction force is generated, thereby wrapping and protecting the protective cover and the signal enhancer. The specific contents are as follows: 1. By setting up a tunnel adjustment mechanism, not only can the bidirectional motor be used to drive the driving shaft and the active sprocket to rotate, but also the meshing connection characteristics between the active sprocket, the transmission chain and the driven sprocket can be used to make the driven sprocket drive the transmission connecting shaft and the connecting roller to rotate, and the meshing connection characteristics between the meshing gear ring and the meshing rack can be used to realize the movement of the connecting bracket and the movable bracket, and the transmission connecting shaft can be used to drive the vibration protrusion to rotate, and the vibration protrusion can knock the first connecting rod and drive the vibration sliding sleeve and the vibration connecting column to move. Under the elastic force of the first spring telescopic rod and the second compression spring, the movement of the compression block can be realized, and the compression block can be pressed. The blocks can achieve stable support of the connecting bracket and the mobile bracket on the arched slide rail and the vertical slide rail, thereby improving the stability of the tunnel adjustment mechanism. By changing the position of the signal booster on the arched slide rail and the vertical slide rail, the signal strength of the signal booster can be adjusted. By setting the arched slide rail and the vertical slide rail, the signal booster can be installed in the tunnel. After the signal booster is installed, the position of the signal booster can be adjusted according to changes in the environment. Since the signal of the signal booster is affected by environmental factors, it is necessary to adjust the signal booster to the position with the best signal according to changes in the environment, thereby improving the strength of the wireless communication signal. 2. By setting up the installation mechanism, not only can the support block be driven to squeeze the second spring telescopic rod and the support spring by pressing the clamping disk, but under the action of the clamping rotating rod, the clamping sliding sleeve drives the clamping connecting rod to move around the clamping disk, so that the clamping connecting rod drives the clamping arm to expand outward. When the clamping hook is separated from the clamping groove, the connecting block can be taken out from the inside of the clamping hook, thereby realizing the rapid disassembly of the signal enhancer. When the signal enhancer needs to be installed, the connecting block can be aligned with the support block, and the elastic force of the support spring and the clamping spring can be used to drive the clamping arm to rotate inward. When the clamping hook is engaged with the clamping groove, the connecting block can be fixed, thereby realizing the rapid disassembly of the signal enhancer. By starting the rotating motor to drive the rotating worm to rotate, the rotating worm and the rotating worm wheel are engaged to drive the rotating worm wheel to rotate the protective cover, thereby changing the direction of the signal enhancer, thereby adjusting the signal strength of the signal enhancer. When a train passes by, an airflow field is generated, thereby generating a certain suction force, which will cause the signal enhancer to be sucked toward the train. By setting a protective arc plate and a closing block, the protective arc plate and the closing block can be contracted through the protective rotating rod and the protective spring when suction is generated, thereby wrapping and protecting the protective cover and the signal enhancer. At the same time, under the action of suction, the clamping plate moves outward, making the clamping arm and the clamping hook more stable, further improving the stability of the signal enhancer.
