Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of installation structure of vehicle-ground communication combined antenna. BACKGROUND

[0002] As an advanced track transportation tool, high-speed maglev train attracts more and more attention with its high speed, safety, comfort and environmental protection advantages. The stable and efficient train-ground communication system is essential for the safe and reliable operation of the train. The train-ground communication system is an important part of the train control system, responsible for data transmission between the train and the ground control center, used for train positioning, speed control, signal transmission and interaction of various safety information. In high-speed maglev trains, due to the extremely high speed of the train, higher requirements are put forward for the real-time and reliability of the communication system. Currently, high-speed maglev trains usually use wireless communication technology based on millimeter waves to meet the demand for high-speed data transmission.

[0003] The millimeter wave communication system usually consists of ground base stations and vehicle-mounted antennas. The ground base stations are arranged along the track, and each base station contains one or more antennas for communication with the train. These antennas need to be installed on the base station pole beside the track and accurately pointed and adjusted to ensure stable communication connection with the high-speed running train. Since the antenna is installed at a high position, high-altitude operation is usually required for installation and maintenance, which poses a safety risk to the workers.

[0004] Currently, the installation structure of the trackside antenna is mainly direct fixation type. This installation method directly fixes the antenna on the base station pole, which is simple in structure and convenient to install. However, this method also has obvious disadvantages. If the antenna needs to be maintained or replaced, high-altitude operation needs to be performed again, which is time-consuming and laborious, and poses a safety risk.

[0005] It is difficult to adjust the angle and direction of the antenna at high altitude, and professional tools and skilled operators are required.

[0006] The installation and maintenance of the antenna usually require the cooperation of multiple workers, high-altitude operation, and complicated operation steps, which are prone to misoperation. Some existing installation structures lack reliable anti-falling measures, and once the antenna or other components accidentally fall off, it will pose a serious threat to ground personnel and equipment. The high-altitude operation environment is complex and variable, and factors such as wind, rain, snow and high temperature will increase the difficulty and risk of operation.

[0007] In order to ensure the stability and reliability of the high-speed maglev train communication system and the personal safety of high-altitude workers, it is urgent to develop a more safe and reliable installation structure for vehicle-ground communication antennas. INVENTION CONTENTS

[0028] Transceiver (BST), it is located between guide rail 5 and clamping plate 4, and can slide along guide rail 5 between the inside and outside of frame;This design makes transceiver can be conveniently slid in and out, simplifies installation and maintenance process.

[0029] Wherein, handle 11 drives clamping plate 4 to move, to clamp transceiver between guide rail 5 and clamping plate 4;This clamping mechanism can firmly fix transceiver, prevent it from accidentally falling in aerial work or train operation process.More specifically, rotating handle 11 will drive clamping plate 4 to rotate around its pivot point, so as to clamp or release transceiver.

[0030] Further, a locking pin 12 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, preventing the transceiver from falling even if the handle 11 is accidentally loosened.

The design of multiple clamping plates 4 can provide more uniform clamping force and better adapt to different types of transceivers. The pivot connection makes the movement of the clamping plate 4 more flexible, making it easier to clamp and release the transceiver.

[0032] Further, the frame body 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 both 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 body to the base station pole.

At least a part of the safety rope 2 is wrapped around the main bracket 10. This design can limit the swing amplitude when the transceiver falls, reducing the potential harm to personnel and equipment.

[0034] Specifically, the frame is the base of the entire mounting structure, which has mounting structures such as bolt holes or buckles for connecting the base station pole. In this embodiment, the top surface and the bottom surface of the frame have an included angle of 15 degrees, and the area of the top surface is larger than that of the bottom surface. The bottom surface is in the horizontal plane after installation. This inclined design can make it easier for rainwater to flow away and prevent water accumulation, further improving 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 bolt connection. The fairing 9 is arranged on both sides of the front and rear of the outer frame 8, and cooperates with the outer frame 8 to form a closed space for accommodating the main support 10, the guide rail 5, the clamping plate 4, the handle 11 and the transceiver (BST).

The size of the transceiver matches the spacing between the guide rail 5 and the clamping plate 4 to ensure that it can be smoothly slid in and out.

[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, which can 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, through a fixed ring or a buckle to the upper end of the back plate 7. The other end is connected to the hook 21. At least a part of the safety rope 2 is wrapped around the main support 10, forming a loop structure. This design can limit the swing amplitude of the transceiver when falling, reducing the potential harm to personnel and equipment.

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

[0043] During installation of the transceiver, first, the transceiver is slid along the guide rail 5 into the frame until it reaches the predetermined position. Then, the handle 11 is pulled down to drive the clamping plate 4 to rotate around the pivot connection 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, the lock pin 12 is inserted to lock the clamping plate 4, further ensuring the secure fixation of the transceiver. During installation, the hook 21 of the safety rope is fixedly connected with the transceiver, which can prevent the transceiver from falling accidentally.

[0044] During disassembly of the transceiver, first, the lock pin 12 is pulled out, and then the handle 11 is lifted up to make the clamping plate 4 away from the transceiver. Finally, the transceiver is slid along the guide rail 5 out of the frame.

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