Description

Technical Field

[0001] This invention relates to the field of railway communication technology, specifically to a railway wireless communication signal enhancement device. Background Technology

[0002] Railway communication refers to the technologies and equipment used in railway transportation production and construction to transmit and process various information using various communication methods. Digital railway trackside safety communication equipment mainly includes a series of devices that use modern information technology to achieve high-speed and reliable data exchange between trains and the ground. These devices are crucial for ensuring train operation safety, improving transportation efficiency, and realizing intelligent management. The following are some of the main 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 that can improve the installation efficiency of signal transmission equipment and enable rapid installation. By setting a sleeve rod and an adjusting rod, and simultaneously slidingly connecting the signal transmission equipment to one end of the sleeve rod, the height of the signal transmission equipment can be adjusted by adjusting the height of the sleeve rod, thus improving the efficiency of height adjustment during the installation process and consequently improving the installation efficiency. Furthermore, by setting a first friction tooth and a second friction tooth on the outer wall of the adjusting rod and the inner wall of the sleeve rod respectively, and by staggering the first and second friction teeth, the signal transmission equipment can be temporarily held at a suitable height after adjustment, facilitating the installation of the limiting nut and connecting screw, thereby improving installation efficiency. However, this patent still has the following problems in practical use:

[0004] While this digital railway trackside safety communication device enables rapid installation of signal transmission equipment, railway transportation requires channel signal enhancement equipment to improve wireless communication signals, especially in tunnels where signals are weak. However, signal enhancement is affected by the installation location, direction, and angle. In tunnels, arbitrary angles cannot be changed, affecting the signal enhancement effect. Furthermore, passing trains create airflow, generating suction that can pull the signal enhancement equipment towards the train, potentially causing damage.

[0005] Therefore, a railway wireless communication signal enhancement device is proposed to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a railway wireless communication signal enhancement device to solve the problems mentioned in the background art. In railway transportation, there is a need for channel signal enhancement equipment to improve the railway's wireless communication signal, especially in tunnels. Since the signal is weak inside the tunnel, signal enhancement equipment is needed to improve the wireless communication signal. However, the signal is affected by the installation position, direction, and angle. In a tunnel, the angle cannot be changed arbitrarily, which affects the signal enhancement effect of the signal enhancement equipment. At the same time, when a train passes by, an airflow field is generated, which generates a certain suction force, causing the signal enhancement equipment to be sucked towards the train, thus damaging the signal enhancement equipment.

[0019] Preferably, the output end of the rotating motor is fixedly connected to a rotating worm gear, the bottom of the rotating worm gear is meshed with a rotating worm wheel, the rotating worm wheel is rotatably connected to the mounting plate, a protective cover is fixedly installed on the outer side of the rotating worm wheel, the signal enhancer is fixedly installed inside the protective cover, and a plurality of signal enhancement holes are opened on the surface of the protective cover.

[0020] Preferably, a protective sliding rod is fixedly installed on all four sides of the inside of the protective cover, a protective spring is fixedly installed in the middle of the protective sliding rod, and a protective sliding sleeve is fixedly installed at both ends of the protective spring. The protective sliding sleeve is slidably connected to the protective sliding rod, a protective rotating rod is rotatably connected to the outside of the protective sliding sleeve, a protective arc-shaped plate is rotatably connected to the end of the protective rotating rod, and a closing block is fixedly installed at the end of the protective arc-shaped plate.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: This railway wireless communication signal enhancement device, by setting arched slide rails and vertical slide rails, allows the signal enhancer to be installed in the tunnel. After installation, the position of the signal enhancer can be adjusted according to environmental changes. Since the signal of the signal enhancer is affected by environmental factors, it is necessary to adjust the signal enhancer to the best position according to environmental changes, thereby improving the strength of the wireless communication signal. When a train passes by, an airflow field is generated, which produces a certain suction force, causing the signal enhancer to be sucked towards the train. By setting a protective arc plate and a sealing block, when suction force is generated, the protective arc plate and sealing block can be contracted through the protective rotating rod and protective spring, thereby wrapping and protecting the protective cover and the signal enhancer. The specific details are as follows:

[0022] 1. By setting up a tunnel adjustment mechanism, not only can a bidirectional motor drive the drive shaft and the active sprocket to rotate, but also the meshing connection between the active sprocket, the transmission chain, and the driven sprocket can be used to drive the transmission connecting shaft and the connecting roller to rotate. Furthermore, the meshing connection between the meshing toothed ring and the meshing rack allows for the movement of the connecting bracket and the movable bracket. The transmission connecting shaft drives the vibrating protrusion to rotate, which in turn strikes the first connecting rod, causing the vibrating sleeve and the vibrating connecting column to move. Under the elastic force of the first spring telescopic rod and the second pressing spring, the pressing block can move, thereby achieving the pressing effect. The block enables stable support for the connecting bracket and the movable bracket on the arched slide rail and the vertical slide rail, improving the stability of the tunnel adjustment mechanism. By changing the position of the signal enhancer on the arched slide rail and the vertical slide rail, the signal strength of the signal enhancer can be adjusted. The signal enhancer can be installed in the tunnel by setting the arched slide rail and the vertical slide rail. After the signal enhancer is installed, its position 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 best position according to changes in the environment, thereby improving the strength of the wireless communication signal.

[0023] 2. By setting up an installation mechanism, not only can the pressing of the clamping plate cause the support block to squeeze the second spring telescopic rod and the support spring, but also, under the action of the clamping rotating rod, the clamping sliding sleeve can move the clamping connecting rod to the periphery of the clamping plate, causing the clamping connecting rod to drive the clamping arm to unfold outward. When the clamping hook separates from the clamping slot, the connecting block can be removed from the inside of the clamping hook, thus achieving quick disassembly of the signal enhancer. When it is necessary to install the signal enhancer, 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 cause the clamping arm to drive the clamping hook to rotate inward. When the clamping hook engages with the clamping slot, the connecting block can be fixed, thus enabling quick disassembly of the signal enhancer. The starting motor drives the rotating worm gear to rotate. Utilizing the meshing connection between the rotating worm gear and the rotating worm wheel, the rotating worm wheel drives the protective cover to rotate, thereby changing the direction of the signal booster and adjusting its signal strength. When a train passes by, an airflow field is generated, creating a certain suction force that pulls the signal booster towards the train. By setting up a protective arc-shaped plate and a sealing block, when suction is generated, the protective rotating rod and protective spring can cause the protective arc-shaped plate and sealing block to retract, thus wrapping and protecting the protective cover and the signal booster. At the same time, under the action of suction, the clamping plate moves outward, making the clamping arm and clamping hook clamp more stable, further improving the stability of the signal booster.

A meshing rack 103 is fixedly installed on one side of the inner surface of both the arched slide rail 101 and the vertical slide rail 102. A connecting bracket 104 is provided on one side of the middle of the vertical slide rail 102. Movable brackets 105 are fixedly installed on both sides of the connecting bracket 104. A sprocket limit cover 106 is fixedly installed on the outer side of each of the two movable brackets 105. A bidirectional electric... The bidirectional motor 107 has a drive shaft 108 fixedly mounted on both output ends. A drive sprocket 109 is fixedly mounted on the end of the drive shaft 108. A transmission chain 110 is meshed with the outer side of the drive sprocket 109. A driven sprocket 111 is meshed with the inner side of the transmission chain 110 away from the drive sprocket 109. A transmission connecting shaft 112 is fixedly connected to the side of the driven sprocket 111. The bidirectional motor 107 drives the drive shaft 108 and the drive sprocket 109 to rotate. The meshing connection between the drive sprocket 109, the transmission chain 110, and the driven sprocket 111 causes the driven sprocket 111 to drive the transmission connecting shaft 112 and the connecting roller 114 to rotate. The meshing connection between the meshing toothed ring 115 and the meshing rack 103 enables the movement of the connecting bracket 104 and the movable bracket 105.

[0038] Please see Figures 5-7Several vibrating protrusions 113 are fixedly installed on the outer side of the transmission connecting shaft 112. A connecting roller 114 is fixedly installed at the end of the transmission connecting shaft 112. A meshing gear ring 115 is fixedly installed on the outer side of the connecting roller 114. The meshing gear ring 115 meshes with the meshing rack 103. A first compression spring 116 is fixedly installed on the side of each of the two moving supports 105 that is close to each other. A roller support 117 is fixedly installed at the end of the first compression spring 116. A compression roller 118 is rotatably connected inside the roller support 117. A vibration groove 119 is opened inside the moving support 105. The interior is symmetrically equipped with two vibration slide rods 120. Vibration sleeves 121 are slidably connected to the outer sides of each vibration slide rod 120. Vibration springs 122 are fixedly installed on one side of each vibration sleeve 121. Vibration connecting columns 123 are fixedly installed to the outer sides of the vibration sleeves 121. A first spring telescopic rod 124 is fixedly installed at the end of the vibration connecting column 123. A second compression spring 125 is slidably connected to the outer side of the first spring telescopic rod 124. A compression block 126 is fixedly installed at the end of the second compression spring 125. The compression block 126 is in close contact with the arched slide rail 101 and the vertical slide rail 102. A first connecting rod 127 is fixedly connected between the vibrating sleeves 121. The transmission connecting shaft 112 drives the vibrating protrusion 113 to rotate. The vibrating protrusion 113 strikes the first connecting rod 127, causing the vibrating sleeves 121 and the vibrating connecting column 123 to move. Under the elastic force of the first spring telescopic rod 124 and the second compression spring 125, the pressing block 126 can move. The pressing block 126 provides stable support for the connecting bracket 104 and the moving bracket 105 on the arched slide rail 101 and the vertical slide rail 102, improving the stability of the tunnel adjustment mechanism 1. This is achieved by changing the signal amplifier. The position of 221 on the arched slide rail 101 and the vertical slide rail 102 allows for adjustment of the signal strength of the signal enhancer 221. By setting the arched slide rail 101 and the vertical slide rail 102, the signal enhancer 221 can be installed in the tunnel. After installation, the position of the signal enhancer 221 can be adjusted according to changes in the environment to achieve the best signal strength. Since the signal of the signal enhancer 221 is affected by environmental factors, it is necessary to adjust the signal enhancer 221 to the best signal strength according to changes in the environment, thereby improving the strength of the wireless communication signal.

[0039] Please see Figure 1 , Figures 8-10The installation mechanism 2 includes a fixed plate 201. A second spring telescopic rod 202 is fixedly installed at the center of the fixed plate 201. A support spring 203 is slidably connected to the outer side of the second spring telescopic rod 202. A support block 204 is fixedly installed at the end of the support spring 203. A clamping rotating rod 205 is rotatably connected around the fixed plate 201. A clamping sliding sleeve 206 is rotatably connected to the end of the clamping rotating rod 205. A clamping sliding rod 207 is slidably connected inside the clamping sliding sleeve 206. A clamping spring 208 is fixedly installed on one side of the clamping sliding rod 207. A clamping plate 209 is fixedly installed on the outer side of the clamping sliding rod 207. A clamping connecting rod 210 is rotatably connected to the outer side of 206. A clamping arm 211 is rotatably connected to the end of the clamping connecting rod 210. A clamping hook 212 is fixedly installed at the end of the clamping arm 211. The clamping arm 211 is rotatably connected to the clamping disk 209. A support block 204 is fixedly connected to the clamping disk 209. A connecting block 213 is attached to the outer side of the support block 204. A clamping groove 214 is formed around the connecting block 213. The clamping hook 212 is engaged with the connecting block 213 through the clamping groove 214. An installation disk 215 is fixedly installed on the outer side of the connecting block 213. A rotating bracket 216 is symmetrically installed on one side of the installation disk 215. A rotating motor 217 is fixedly installed on the outside of the mounting plate 216. A rotating worm gear 218 is fixedly connected to the output end of the rotating motor 217. A rotating worm wheel 219 is meshed with the bottom of the rotating worm gear 218. The rotating worm wheel 219 is rotatably connected to the mounting plate 215. A protective cover 220 is fixedly installed on the outside of the rotating worm wheel 219. A signal amplifier 221 is fixedly installed inside the protective cover 220. By pressing the clamping plate 209, the support block 204 is driven to compress the second spring telescopic rod 202 and the support spring 203. Under the action of the clamping rotating rod 205, the clamping sliding sleeve 206 drives the clamping connecting rod 210 to move around the clamping plate 209. The clamping connecting rod 210 drives the clamping arm 211 to unfold outward. When the clamping hook 212 separates from the clamping groove 214, the connecting block 213 can be removed from the inside of the clamping hook 212, thereby realizing the quick disassembly of the signal enhancer 221. When it is necessary to install the signal enhancer 221, the connecting block 213 can be aligned with the support block 204. Using the elastic force of the support spring 203 and the clamping spring 208, the clamping arm 211 drives the clamping hook 212 to rotate inward. When the clamping hook 212 engages with the clamping groove 214, the connecting block 213 can be fixed, thereby enabling the quick disassembly of the signal enhancer 221.

[0040] Please see Figures 10-11The protective cover 220 has several signal enhancement holes 222 on its surface. Protective sliding rods 223 are fixedly installed around the inside of the protective cover 220. A protective spring 224 is fixedly installed in the middle of the protective sliding rod 223. Protective sliding sleeves 225 are fixedly installed at both ends of the protective spring 224. The protective sliding sleeves 225 are slidably connected to the protective sliding rod 223. A protective rotating rod 226 is rotatably connected to the outside of the protective sliding sleeve 225. A protective arc-shaped plate 227 is rotatably connected to the end of the protective rotating rod 226. A sealing block 228 is fixedly installed at the end of the protective arc-shaped plate 227. The rotating worm 218 is driven to rotate by starting the rotating motor 217. Utilizing the meshing connection between the rotating worm 218 and the rotating worm wheel 219, the rotation... The worm gear 219 drives the protective cover 220 to rotate, thereby changing the direction of the signal enhancer 221 and adjusting its signal strength. When a train passes by, an airflow field is generated, which produces a certain suction force, causing the signal enhancer 221 to be drawn towards the train. By setting up the protective arc plate 227 and the sealing block 228, when the suction force is generated, the protective rotating rod 226 and the protective spring 224 can realize the contraction of the protective arc plate 227 and the sealing block 228, thereby wrapping and protecting the protective cover 220 and the signal enhancer 221. At the same time, under the action of suction force, the clamping plate 209 moves outward, making the clamping arm 211 and the clamping hook 212 clamp more stably, further improving the stability of the signal enhancer 221.

[0041] Working principle: Before using this railway wireless communication signal enhancement device, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 11 As shown, firstly, by pressing the clamping disc 209, the support block 204 is driven to squeeze the second spring telescopic rod 202 and the support spring 203. Under the action of the clamping rotating rod 205, the clamping sliding sleeve 206 drives the clamping connecting rod 210 to move around the clamping disc 209, causing the clamping connecting rod 210 to drive the clamping arm 211 to unfold outward. When the clamping hook 212 separates from the clamping groove 214, the connecting block 213 can be taken out from the inside of the clamping hook 212, thereby realizing the quick disassembly of the signal enhancer 221. When it is necessary to install the signal enhancer 221, the connecting block 213 can be aligned with the support block 204. Using the elastic force of the support spring 203 and the clamping spring 208, the clamping arm 211 drives the clamping hook 212 to rotate inward. When the clamping hook 212 is engaged with the clamping groove 214, the connecting block 213 can be fixed, thereby enabling the quick disassembly of the signal enhancer 221.

[0042] Secondly, by starting the rotating motor 217, the rotating worm 218 is driven to rotate. Utilizing the meshing connection between the rotating worm 218 and the rotating worm wheel 219, the rotating worm wheel 219 drives the protective cover 220 to rotate, thereby changing the direction of the signal enhancer 221 and adjusting its signal strength. When a train passes by, an airflow field is generated, resulting in a certain suction force that causes the signal enhancer 221 to be drawn towards the train. By setting up the protective arc plate 227 and the sealing block 228, when suction is generated, the protective rotating rod 226 and the protective spring 224 can achieve the contraction of the protective arc plate 227 and the sealing block 228, thereby wrapping and protecting the protective cover 220 and the signal enhancer 221. At the same time, under the action of suction, the clamping plate 209 moves outward, making the clamping arm 211 and the clamping hook 212 clamp more stably, further improving the stability of the signal enhancer 221.

[0043] Finally, the bidirectional motor 107 drives the drive shaft 108 and the drive sprocket 109 to rotate. Utilizing the meshing connection between the drive sprocket 109, the transmission chain 110, and the driven sprocket 111, the driven sprocket 111 drives the transmission connecting shaft 112 and the connecting roller 114 to rotate. Utilizing the meshing connection between the meshing toothed ring 115 and the meshing rack 103, the connecting bracket 104 and the movable bracket 105 can move. The transmission connecting shaft 112 drives the vibrating protrusion 113 to rotate. The vibrating protrusion 113 strikes the first connecting rod 127, causing the vibrating sleeve 121 and the vibrating connecting column 123 to move. Under the elastic force of the first spring telescopic rod 124 and the second clamping spring 125, the clamping block 126 can move. The clamping block 126 enables... The connecting bracket 104 and the movable bracket 105 provide stable support on the arched slide rail 101 and the vertical slide rail 102, improving the stability of the tunnel adjustment mechanism 1. By changing the position of the signal enhancer 221 on the arched slide rail 101 and the vertical slide rail 102, the signal strength of the signal enhancer 221 can be adjusted. The signal enhancer 221 can be installed in the tunnel by setting the arched slide rail 101 and the vertical slide rail 102. After the signal enhancer 221 is installed, its position can be adjusted according to changes in the environment to achieve the best signal strength. Since the signal of the signal enhancer 221 is affected by environmental factors, it is necessary to adjust the signal enhancer 221 to the best signal strength according to changes in the environment, thereby improving the strength of the wireless communication signal.
