Description

Technical Field

[0001] This utility model relates to the field of railway construction safety technology, and more specifically, to a vehicle approach warning device for construction safety. Background Technology

[0002] During railway construction, the safety of construction workers is always a primary concern. The high speed of trains poses a significant threat to personnel and equipment in the construction area. Traditional methods of judging the approach of trains by manual observation are limited by ordinary human senses, have short warning times, and are prone to accidents due to human negligence.

[0003] While existing train proximity warning systems can provide early warning to some extent, they still have shortcomings in terms of warning distance, response speed, and environmental adaptability. Furthermore, they are usually installed in a fixed manner, making it difficult to quickly adapt to dynamic changes in the construction site.

[0004] Therefore, this application proposes a vehicle approach warning device for construction safety. Utility Model Content

[0005] (a) Purpose of the utility model

[0006] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a train approach warning device for construction safety, in order to solve the problems of untimely train approach warnings, high labor costs, and the inconvenience of existing warning devices in terms of mobility and adaptability to dynamic changes in construction sites.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A vehicle approach warning device for construction safety includes a main warning device and a sub-warning device, wherein the sub-warning device is separately disposed on the main warning device;

[0010] The main early warning device includes a lidar, a hand-cranked lifting rod, a chassis, and wheels. The chassis is equipped with a hand-cranked lifting rod, and an angle adjustment mechanism is fixed to the top of the hand-cranked lifting rod. The lidar is installed on the angle adjustment mechanism. A column is provided on the right side of the hand-cranked lifting rod, and a main control box is installed on the ring surface of the column. Two sets of wheels are provided on each of the front and rear sides of the bottom of the chassis. A push-pull handle is installed at the right end of the chassis.

[0011] The sub-early warning device includes an alarm light, an alarm horn, a sub-control box, a fixed support column, and a counterweight base. The fixed support column has a counterweight base at its bottom, and the sub-control box is installed on the ring surface of the fixed support column. Several sets of alarm horns are installed on the ring surface of the fixed support column above the sub-control box. An alarm light is installed on the top of the fixed support column. The alarm horn and the alarm light are electrically connected to the sub-control box via wires.

[0012] Furthermore, the angle adjustment mechanism includes a rotating base, a housing, a base frame, a servo motor, and a drive shaft. The base frame is fixed to the top of the hand-cranked lifting rod, and a housing is provided on it. The servo motor is installed inside the housing. A rotating base is provided on the upper side of the housing, and the bottom of the rotating base is connected to the output end of the servo motor through the drive shaft.

[0013] Furthermore, the top of the column is equipped with two sets of solar panels, and a power supply box is installed on the chassis between the hand-cranked lifting rod and the column, and the solar panels are electrically connected to the power supply box.

[0014] Furthermore, the chassis is equipped with two sets of adjustable outriggers on each of its front and rear sides.

[0015] Furthermore, the base in the front area of ​​the column is provided with a mounting bracket for placing the sub-early warning device, and the specifications of the mounting bracket are adapted to the counterweight base of the sub-early warning device.

[0016] Furthermore, both the main control box and the sub-control box are equipped with a microprocessor control module, a wireless transmission module, and a power supply module.

[0017] (III) Working Principle

[0018] The main early warning device is moved to a location 4-8 kilometers ahead of the construction area using the wheels and push-pull handles. The adjustable outriggers are adjusted to keep the equipment level and stable. The lidar is then adjusted to a suitable detection height using a hand-cranked lifting rod. The angle adjustment mechanism is used to drive the rotating base to rotate and adjust the horizontal detection angle of the lidar to ensure coverage of the direction of oncoming vehicles. The solar panel works in conjunction with the power supply box to power the equipment and extend its battery life.

[0019] The sub-early warning device is detached from the main early warning device via a mounting bracket, placed in the construction area, and kept stable by a counterweight base. Its power supply is provided by its own power supply module.

[0020] The main early warning device's lidar emits a laser beam and receives reflected signals in real time to detect approaching vehicles. When the lidar detects an approaching train, it transmits the detection signal to the main control box, which then sends the warning information to the sub-control box of the sub-early warning device via a wireless transmission module. Upon receiving the signal, the sub-control box controls the alarm lights on top to flash and simultaneously controls the alarm horns on the fixed support pillars to emit a high-decibel sound, thus issuing a warning to personnel in the construction area through a combination of sound and light.

[0034] Example:

[0035] like Figures 1 to 6 As shown, a vehicle approach warning device for construction safety includes a main warning device 1 and a sub-warning device 2, with the sub-warning device 2 separately mounted on the main warning device 1.

[0036] The main warning device 1 includes a lidar 11, a hand-cranked lifting rod 13, a chassis 14, and wheels 15. The hand-cranked lifting rod 13 is mounted on the chassis 14. An angle adjustment mechanism 12 is fixed on the top of the hand-cranked lifting rod 13. The lidar 11 is mounted on the angle adjustment mechanism 12. A column 111 is located on the right side of the hand-cranked lifting rod 13. A main control box 110 is mounted on the ring surface of the column 111. Two sets of wheels 15 are located on the front and rear sides of the bottom of the chassis 14. A push-pull handle 19 is installed at the right end of the chassis 14.

[0037] In the above technical solution, the walking wheels 15 combined with the push-pull handle 19 enable convenient movement of the equipment to adapt to the dynamic changes in the construction site; the hand-cranked lifting rod 13 allows manual adjustment of the detection height of the lidar 11 to adapt to different construction environments such as uneven ground and obstructed by obstacles; the angle adjustment mechanism 12 enables precise horizontal adjustment of the lidar 11 to cover a wider detection area; the lidar 11 emits a laser beam and receives reflected signals to detect oncoming vehicle information in real time, and in conjunction with the angle adjustment mechanism 12, dynamically adjusts the detection range to adapt to changes in the layout of the construction site.

[0038] The sub-early warning device 2 includes an alarm light 21, an alarm horn 22, a sub-control box 23, a fixed support 24 and a counterweight base 25. The bottom of the fixed support 24 is provided with a counterweight base 25. The sub-control box 23 is installed on the ring surface of the fixed support 24. Several sets of alarm horns 22 are installed on the ring surface of the fixed support 24 above the sub-control box 23. The top of the fixed support 24 is provided with an alarm light 21.

[0039] The sub-early warning device 2 is placed in the construction area to receive the early warning information sent by the main early warning device 1, and to control the alarm light 21 to flash and the alarm horn 22 to emit a high-decibel sound to issue an early warning signal. The sound and light linkage enhances the early warning effect and achieves timely early warning.

[0040] It should be noted that the lidar 11 uses the Horn-RT model radar, which has a detection range of 300 meters and a detection angle range of 90-13 degrees.

[0041] In addition, the main early warning device 1 needs to be placed 4-8 kilometers in front of the construction area in actual use, and can provide early warning more than 2 minutes in advance.

[0042] In this embodiment, the angle adjustment mechanism 12 includes a rotating base 121, a housing 122, a base frame 123, a servo motor 124, and a drive shaft 125. The base frame 123 is fixed to the top of the hand-cranked lifting rod 13, and the housing 122 is mounted on it. The servo motor 124 is installed inside the housing 122. The rotating base 121 is located on the upper side of the housing 122, and the bottom of the rotating base 121 is connected to the output end of the servo motor 124 through the drive shaft 125. This design enables precise horizontal adjustment of the lidar 11 through the angle adjustment mechanism 12, covering a wider detection area. The servo motor 124 drives the rotating base 121 to rotate through the drive shaft 125, thereby adjusting the detection angle of the lidar 11.

[0043] In this embodiment, two sets of solar panels 112 are provided on the top of the column 111. A power supply box 16 is provided on the chassis 14 between the hand-cranked lifting rod 13 and the column 111. The power supply box 16 is used to supply power to the device. The solar panels 112 are electrically connected to the power supply box 16. The solar panels 112 provide auxiliary power to the device, extend the battery life, and reduce the frequency of manual charging.

[0044] It should be noted that the charging principle of solar panel 112 is existing technology and will not be elaborated here.

[0045] In this embodiment, the chassis 14 is provided with two sets of adjustable support legs 17 on each of the front and rear sides, which can be adjusted to be level when the equipment is placed, thereby enhancing stability and avoiding the risk of tipping over due to uneven ground.

[0046] In this embodiment, a mounting base 18 for placing the sub-early warning device 2 is provided on the chassis 14 in the front area of ​​the column 111. The specifications of the mounting base 18 are adapted to the counterweight base 25 of the sub-early warning device 2, which facilitates the quick fixing and disassembly of the sub-early warning device 2.

[0047] In this embodiment, both the main control box 110 and the sub-control box 23 are equipped with a microprocessor control module, a wireless transmission module and a power supply module. The microprocessor control module is used to receive and process the detection data of the lidar 11, and the wireless transmission module is used for signal transmission and triggering alarms.

[0048] The working principle of a vehicle approach warning device used for construction safety:

[0049] The main warning device 1 is moved to a location 4-8 kilometers ahead of the construction area via the wheels 15 and push-pull handles 19. The adjustable outriggers 17 are adjusted to keep the equipment horizontal and stable. The lidar 11 is then adjusted to a suitable detection height via the hand-cranked lifting rod 13. The angle adjustment mechanism 12 and the servo motor 124 drive the rotating base 121 to rotate and adjust the horizontal detection angle of the lidar 11 to ensure coverage of the direction of oncoming vehicles. The solar panel 112 works in conjunction with the power supply box 16 to power the equipment and extend its operating range.

[0050] The sub-early warning device 2 is detached from the main early warning device 1 via the card holder 18, placed in the construction area, and kept stable by the counterweight base 25. Its power supply is provided by its own power supply module.

[0051] The lidar 11 of the main early warning device 1 emits a laser beam and receives reflected signals in real time to detect oncoming trains. When lidar 11 detects an approaching train, it transmits the detection signal to the main control box, which then sends the warning information to the sub-control box 23 of the sub-early warning device 2 via a wireless transmission module. Upon receiving the signal, the sub-control box 23 controls the alarm light 21 on top to flash, and simultaneously controls the alarm horn 22 on the fixed support 24 to emit a high-decibel sound, thus issuing a warning to personnel in the construction area through a combination of sound and light.

[0052] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
