Description

Technical Field

[0001] The invention relates to a mounting structure of a vehicle-to-ground communication combined antenna. Background Art

[0002] As an advanced rail transportation tool, high-speed maglev trains have attracted more and more attention for their advantages such as high speed, safety, comfort and environmental protection. The safe and reliable operation of trains is inseparable from a stable and efficient vehicle-to-ground communication system. The vehicle-to-ground communication system is an important part of the train control system, responsible for data transmission between the train and the ground control center, and used for train positioning, speed control, signal transmission and interaction of various safety information. In high-speed maglev trains, due to the extremely high running speed of the train, higher requirements are placed on the real-time and reliability of the communication system. At present, high-speed maglev trains usually use millimeter-wave based wireless communication technology to meet the needs of high-speed data transmission.

[0003] Millimeter wave communication systems usually consist of ground base stations and vehicle-mounted antennas. The ground base stations are arranged along the tracks, and each base station contains one or more antennas for communicating with the trains. These antennas need to be installed on base station poles beside the tracks and accurately pointed and adjusted to ensure a stable communication connection with high-speed trains. Due to the high installation position of the antennas, high-altitude operations are usually required for installation and maintenance, which poses a safety risk to the operators.

[0004] At present, the installation structure of trackside antennas is mainly direct fixing, which fixes the antenna directly on the base station pole, with simple structure and convenient installation. However, the disadvantages of this method are also obvious. If the antenna needs to be maintained or replaced, it is necessary to re-do the high-altitude operation, which is time-consuming and labor-intensive, and there are safety risks.

[0005] It is difficult to adjust the angle and direction of the antenna at high altitudes, which requires professional tools and skilled operators.

[0006] The installation and maintenance of antennas usually require the cooperation of multiple staff members to perform aerial work. The operation steps are cumbersome and prone to misoperation. Some existing installation structures lack reliable anti-fall measures. Once the antenna or other components fall off accidentally, it will pose a serious threat to ground personnel and equipment. The aerial work environment is complex and changeable. Factors such as wind, rain, snow, and high temperature will increase the difficulty and risk of the operation.

[0007] In order to ensure the stability and reliability of the high-speed maglev train communication system and the personal safety of workers working at heights, a safer and more reliable vehicle-to-ground communication antenna installation structure is urgently needed. Summary of the invention

[0008] The present invention aims at these problems existing in the prior art and proposes a novel installation structure of a vehicle-to-ground communication combined antenna, aiming to improve the safety of aerial operations and facilitate the installation, maintenance and replacement of the antenna.

[0009] The present invention solves the above technical problems through the following technical solutions:

[0010] A mounting structure for a vehicle-to-ground communication combination antenna comprises: a frame having a mounting structure for connecting to a base station pole; by connecting the frame to the base station pole, the entire antenna structure can be firmly mounted beside the track, providing stable support for other components. A main bracket is fixed to the frame; as the main load-bearing component of the antenna, the main bracket is fixed to the frame to ensure the stability of the structure. A guide rail is fixed to the frame; the guide rail is used to guide the installation and sliding of the transceiver, which is convenient for the installation and maintenance of the transceiver. A clamping plate is connected to the main bracket; the clamping plate cooperates with the main bracket to form a clamping mechanism for fixing the transceiver. A handle is connected to the clamping plate and is used to drive the clamping plate to move; the handle is used to operate the clamping mechanism to facilitate the installation and removal of the transceiver. The transceiver is located between the guide rail and the clamping plate and can slide along the guide rail between the outside and the inside of the frame; this design allows the transceiver to slide in and out easily, simplifying the installation and maintenance process. The handle drives the clamping plate to move so as to clamp the transceiver between the guide rail and the clamping plate; this clamping mechanism can firmly fix the transceiver to prevent it from accidentally falling off during high-altitude operations or train operation.

[0011] Preferably, a locking pin is further included, which is inserted between the clamping plate and the transceiver to lock the clamping plate and the transceiver. The addition of the locking pin further enhances the safety of the clamping mechanism, and prevents the transceiver from falling off even if the handle is accidentally loosened.

[0012] Preferably, there are multiple clamping plates, at least one of which is pivotally connected to the main bracket; the handle drives the at least one pivotally connected clamping plate to rotate around its pivot point, so that the clamping plate presses the transceiver, thereby fixing the transceiver on the guide rail. The design of multiple clamping plates can provide a more uniform clamping force and better adapt to different types of transceivers. The pivotal connection makes the movement of the clamping plate more flexible and easier to clamp and release the transceiver.

[0013] Preferably, the frame includes an outer frame, a fairing and a back plate, the outer frame and the back plate are fixedly connected, the fairing is arranged on the front and rear sides of the outer frame, and together with the outer frame forms a closed space for accommodating the main bracket, the guide rail, the clamping plate, the handle and the transceiver, and the back plate is used to fix the frame to the base station pole. This structural design can effectively protect the internal components of the antenna from the influence of the external environment, such as rain, dust, birds, etc.

[0014] Preferably, the top and bottom surfaces of the outer frame have an angle, the area of ​​the top surface is larger than the area of ​​the bottom surface, and the bottom surface is in a horizontal plane after installation. This inclined design allows rainwater to flow away more easily, prevents water accumulation, and further improves the reliability of the antenna.

[0015] Preferably, a safety rope is further included, one end of which is connected to the frame and the other end is connected to a hook, and the hook is fixedly connected to the transceiver during installation. The safety rope provides an additional protection measure, which can prevent the transceiver from falling even if the clamping mechanism fails, thereby ensuring the safety of the personnel working at height.

[0016] Preferably, at least a portion of the safety rope surrounds the main support. This design can limit the swing amplitude of the transceiver when it falls, reducing potential harm to personnel and equipment.

[0017] Preferably, the closed space formed by the fairing accommodates the main bracket, the guide rail, the clamping plate, the handle and the transceiver. This closed design can better protect the internal components of the antenna and extend its service life.

[0018] In summary, the present invention effectively solves the problems of insufficient safety of high-altitude operations, inconvenient installation and maintenance, and poor environmental adaptability in the prior art by providing a safe and reliable transceiver fixing method, a convenient installation and maintenance structure, and comprehensive protective measures, thereby significantly improving the reliability and safety of the high-speed maglev train ground communication system.

[0021] The present invention will be described more clearly and completely below by way of embodiments in conjunction with the accompanying drawings.

[0022] Figure 1It is a structural schematic diagram of the installation structure of the vehicle-to-ground communication combined antenna according to one embodiment of the present invention. Figure 2 FIG. 1 is a schematic diagram of a three-dimensional structure of an installation structure of a vehicle-to-ground communication combined antenna according to an embodiment of the present invention. Figure 1 and Figure 2 As shown, the present invention provides an installation structure of a vehicle-to-ground communication combination antenna, which mainly includes: a frame, a main bracket 10, a guide rail 5, a clamping plate 4, a handle 11, a transceiver (BST) (not shown in the figure), a locking pin 12, a safety rope 2 and a hook 21.

[0023] The frame has a mounting structure for connecting to the base station pole; by connecting the frame to the base station pole, the entire antenna structure can be firmly installed next to the track, providing stable support for other components. In this embodiment, the frame is connected to the base station pole through four bolt holes ( Figure 2 Screw holes are shown) to connect to the base station pole.

[0024] The main bracket 10 is fixed to the frame. The main bracket 10 is the main load-bearing component of the antenna and is fixed to the frame to ensure the stability of the structure. The main bracket 10 is fixed inside the frame by bolts.

[0025] The guide rail 5 is fixed to the frame body; the guide rail 5 is used to guide the installation and sliding of the transceiver, and is convenient for the installation and maintenance of the transceiver. The guide rail 5 is fixed inside the frame body by bolts and is arranged parallel to the main bracket 10.

[0026] The clamping plate 4 is connected to the main bracket 10; the clamping plate 4 cooperates with the main bracket 10 to form a clamping mechanism for fixing the transceiver.

[0027] The handle 11 is connected to the clamping plate 4 and is used to drive the clamping plate 4 to move; the handle 11 is used to operate the clamping mechanism to facilitate installation and removal of the transceiver.

[0028] The transceiver (BST) is located between the guide rail 5 and the clamping plate 4 and can slide along the guide rail 5 between the outside and the inside of the frame; this design allows the transceiver to slide in and out conveniently, simplifying the installation and maintenance process.

[0029] The handle 11 drives the clamping plate 4 to move so as to clamp the transceiver between the guide rail 5 and the clamping plate 4. This clamping mechanism can firmly fix the transceiver to prevent it from accidentally falling off during aerial work or train operation. More specifically, turning the handle 11 will drive the clamping plate 4 to rotate around its pivot point, thereby clamping or releasing the transceiver.

[0030] Furthermore, a locking pin 12 is included, which is inserted between the clamping plate 4 and the transceiver to lock the clamping plate 4 and the transceiver. The addition of the locking pin 12 further enhances the safety of the clamping mechanism, and prevents the transceiver from falling off even if the handle 11 is accidentally loosened.

[0031] Furthermore, there are multiple clamping plates 4, two in this embodiment, which are symmetrically arranged on both sides of the guide rail 5; at least one of the clamping plates 4, two in this embodiment, is pivotally connected to the main bracket 10; the handle 11 drives the clamping plate 4 to rotate around the pivot connection point, so that the clamping plate 4 presses the transceiver, thereby fixing the transceiver on the guide rail 5. The design of multiple clamping plates 4 can provide a more uniform clamping force and better adapt to different types of transceivers. The pivot connection method makes the movement of the clamping plate 4 more flexible and easier to clamp and release the transceiver.

[0032] Further, the frame includes an outer frame 8, a fairing 9 and a back plate 7, the outer frame 8 and the back plate 7 are fixedly connected, the fairing 9 is arranged on the front and rear sides of the outer frame 8, and together with the outer frame 8 forms a closed space for accommodating the main bracket 10, the guide rail 5, the clamping plate 4, the handle 11 and the transceiver, and the back plate 7 is used to fix the frame to the base station pole. This structural design can effectively protect the internal components of the antenna from the influence of the external environment, such as rain, dust, birds, etc. The top and bottom surfaces of the outer frame have an angle of 15 degrees, the area of ​​the top surface is larger than the area of ​​the bottom surface, and the bottom surface is in a horizontal plane after installation. This inclined design can make rainwater flow away more easily, prevent water accumulation, and further improve the reliability of the antenna. The closed space formed by the fairing accommodates the main bracket, the guide rail, the clamping plate, the handle and the transceiver, further improving the protection of the internal components.

[0033] Furthermore, it also includes a safety rope 2, one end of which is connected to the frame, and the other end is connected to a hook 21, and the hook 21 is fixedly connected to the transceiver during installation. The safety rope 2 provides an additional protection measure, which can prevent the transceiver from falling even if the clamping mechanism fails, thereby ensuring the safety of the personnel working at height. At least a portion of the safety rope 2 surrounds the main bracket 10. This design can limit the swing amplitude of the transceiver when it falls, reducing the potential harm to personnel and equipment.

[0034] Specifically, the frame is the basis of the entire mounting structure, and it has a mounting structure for connecting to the base station pole, such as a bolt hole or a buckle. In the present embodiment, the top and bottom surfaces of the frame have an angle of 15 degrees, the area of ​​the top surface is larger than the area of ​​the bottom surface, and the bottom surface is in a horizontal plane after installation. This inclined design allows rainwater to flow away more easily, prevents water accumulation, and further improves the reliability of the antenna. The frame includes an outer frame 8 and a fairing 9. The outer frame 8 and the back plate 7 are fixedly connected, for example, by welding or bolting. The fairing 9 is arranged on the front and rear sides of the outer frame 8, and together with the outer frame 8, forms a closed space for accommodating the main bracket 10, the guide rail 5, the clamping plate 4, the handle 11 and the transceiver (BST). The back plate 7 is used to fix the frame to the base station pole, and is provided with four bolt holes for connecting with the fasteners on the base station pole.

[0035] The main bracket 10 is fixed in the frame, for example, by bolting or welding. It is mainly made of metal materials, such as aluminum alloy or stainless steel, to provide sufficient strength and stability. The main bracket 10 is a supporting structure for the transceiver and the clamping plate, and it maintains a relatively fixed position relationship with the guide rail 5.

[0036] The guide rail 5 is also fixed in the frame and arranged parallel to the main bracket 10. The guide rail 5 is made of stainless steel, and the surface is polished to reduce friction and facilitate the sliding of the transceiver.

[0037] In this embodiment, two clamping plates 4 are provided, which are symmetrically distributed on both sides of the guide rail 5. One end of each clamping plate 4 is pivotally connected to the main bracket 10, for example, by a hinge or a pin. The other end of the clamping plate 4 has an inclined surface, and the angle of the inclined surface is 30 degrees. When the handle 11 drives the clamping plate 4 to rotate around the pivot point, the inclined surface presses the transceiver, thereby fixing it on the guide rail 5.

[0038] The handle 11 is connected to the clamping plate 4, for example, by a pin. The handle 11 is a rotatable rod-shaped structure, one end of which is fixed to the clamping plate 4, and the other end is an operating end. Rotating the handle 11 can drive the clamping plate 4 to rotate around the pivot point, thereby clamping and releasing the transceiver.

[0039] The transceiver (BST) is located between the guide rail 5 and the clamping plate 4 and can slide between the outside and the inside of the frame along the guide rail 5. The outer dimensions of the transceiver match the spacing between the guide rail 5 and the clamping plate 4 to ensure that it can slide in and out smoothly.

[0040] The locking pin 12 is used to lock the clamping plate 4 and the transceiver (BST). When the transceiver is clamped by the clamping plate 4, the locking pin 12 is inserted into the hole between the clamping plate 4 and the transceiver to prevent the clamping plate 4 from loosening, thereby ensuring the safe fixation of the transceiver.

[0041] One end of the safety rope 2 is connected to a fixed end 22 on the frame, for example, connected to the upper end of the back plate 7 through a fixing ring or a buckle. The other end is connected to a hook 21. At least a portion of the safety rope 2 surrounds the main bracket 10 to form a ring structure. This design can limit the swing amplitude of the transceiver when it falls, reducing potential damage to personnel and equipment.

[0042] The hook 21 is connected to the safety rope. During installation, the hook 21 is fixedly connected to the transceiver, for example, hung on a ring or hook on the transceiver. The safety rope and hook provide additional protection measures, which can prevent the transceiver from falling even if the clamping mechanism fails, thereby ensuring the safety of workers working at height.

[0043] When installing the transceiver, first slide the transceiver into the frame along the guide rail 5 until it reaches the predetermined position. Then, pull the handle 11 downward to drive the clamping plate 4 to rotate around the pivot point so that the inclined surface of the clamping plate 4 presses the transceiver. At this time, the transceiver is firmly clamped between the guide rail 5 and the clamping plate 4. Finally, insert the locking pin 12 to lock the clamping plate 4 to further ensure the safe fixation of the transceiver. During the installation process, the hook 21 of the safety rope is fixedly connected to the transceiver to prevent the transceiver from accidentally falling.

[0044] When disassembling the transceiver, first pull out the locking pin 12, then lift the handle 11 upwards to keep the clamping plate 4 away from the transceiver. Finally, slide the transceiver out of the frame along the guide rail 5.

[0045] The installation structure of the vehicle-to-ground communication combined antenna provided by the present invention realizes the rapid, safe and reliable installation and disassembly of the transceiver through the cooperation of the above-mentioned components, effectively solves the problems of insufficient safety of high-altitude operations, inconvenient installation and maintenance, and poor environmental adaptability in the prior art, and significantly improves the reliability and safety of the vehicle-to-ground communication system of high-speed maglev trains.
