[0018] S1: When the device is moved, the handle 1 is turned, and the rotation of the handle 1 drives the rotating shaft 1 to rotate, and the rotation of the rotating shaft 1 drives the small gear to rotate, and the rotation of the small gear drives the large gear to rotate, and the rotation of the large gear drives the threaded rod to rotate, and the threaded rod drives the lifting plate to descend. When the lifting plate descends, it will slide on the surface of the guide rod, thereby improving the stability of the lifting plate during the descent process. The descent of the lifting plate drives the mounting plate and the pulley body to descend until the pulley body contacts the ground. Since the force of manually turning the handle 1 is limited, at this time, in order to lift the base, it is necessary to use tools to assist the base to support it, so as to facilitate the pulley body to continue to descend until the base is separated from the ground, and the device can be moved by the pulley body. At the same time, the handle 1 can also be replaced with a drive motor to drive the rotating shaft 1 to rotate. This adjustment method has a relatively high cost, but there is no need to assist the base. Support;

[0019] S2: When adjusting the height of the warning device, turn the second handle, the second handle drives the second rotating shaft to rotate, the second rotating shaft drives the first bevel gear to rotate, the first bevel gear drives the second bevel gear to rotate, the second bevel gear drives the screw to rotate, the screw drives the lifting column to move up and down, and when the lifting column moves up and down, the limiting convex strip slides inside the strip groove, thereby avoiding the problem of synchronous rotation of the lifting column caused by the screw rotation;

[0020] S3: In order to facilitate the infrared sensor to detect people in different directions, the motor inside the installation shell is opened, and the motor drives the drive shaft to rotate through the output end, and the rotation of the drive shaft drives the fan gear to rotate, and the rotation of the fan gear drives the transmission gear to rotate, and the rotation of the transmission gear drives the rotation rod to rotate, and the rotation of the rotation rod can drive the infrared sensor to rotate, so as to monitor other directions. The infrared sensor monitors the dynamics in the warning area near the warning device. Once a person enters, the infrared sensor transmits a signal to the controller. After receiving the signal, the controller converts the infrared signal into an electrical signal and transmits it to the relay. The relay controls the speaker in the integrated warning device to sound an alarm, thereby further alerting the person;

[0021] S4: When installing the heat dissipation fan body, slide the adjustment block inside the adjustment slot, the adjustment block drives the fixing rod to compress the spring and embed it into the inside of the card block, and then insert the card block on the side of the heat dissipation fan body into the inside of the card slot. At this time, the spring rebounds, thereby driving the fixing rod to insert into the fixing hole on the side of the card slot to achieve the installation of the heat dissipation fan body. At this time, the heat dissipation and cooling of the warning device can be carried out through the heat dissipation fan body.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention is provided with a pulley lifting mechanism. The design of the pulley enables the warning device to be easily moved on the construction site, especially in scenarios where frequent position changes are required, which greatly improves work efficiency. When the device reaches the specified position, the pulley can be retracted to make the base of the device contact the ground, thereby increasing the stability of the device and avoiding shaking or tipping due to the small contact area of ​​the pulley.

Once a person enters, the infrared sensor 517 transmits a signal to the controller 57. After receiving the signal, the controller 57 converts the infrared signal into an electrical signal and transmits it to the relay 58. The relay 58 controls the speaker in the integrated warning device 3 to sound an audible alarm, thereby further alerting the person.

At this time, the spring 532 rebounds, thereby driving the fixing rod 535 to be inserted into the fixing hole on the side of the card slot 52 to realize the installation of the heat dissipation fan body 54. At this time, the heat dissipation and cooling of the warning device can be carried out through the heat dissipation fan body 54.

[0056] By adopting the above technical solution, in order to facilitate the infrared sensor 517 to detect people in different directions, the motor 512 inside the mounting shell 511 is opened, and the motor 512 drives the driving shaft 513 to rotate through the output end. The rotation of the driving shaft 513 drives the fan gear 514 to rotate. The rotation of the fan gear 514 drives the transmission gear 515 to rotate.

The relay 58 controls the speaker in the integrated warning device 3 to sound an alarm, thereby further warning the personnel. When installing the heat dissipation fan body 54, the adjustment block 534 inside the sliding adjustment slot 533 is driven by the adjustment block 534 to drive the fixing rod 535 to compress the spring 532 and embed it into the inside of the card block 531, and then the card block 531 on the side of the heat dissipation fan body 54 is inserted into the inside of the card slot 52. At this time, the spring 532 rebounds, thereby driving the fixing rod 535 to be inserted into the fixing hole on the side of the card slot 52 to realize the installation of the heat dissipation fan body 54. At this time, the warning device can be cooled and dissipated through the heat dissipation fan body 54.

[0060] The present invention further provides a method for using a warning device for transportation engineering, comprising the following steps:

When the lifting plate 67 descends, it will slide on the surface of the guide rod 68, thereby improving the stability of the lifting plate 67 during the descent process. The descent of the lifting plate 67 drives the mounting plate 611 and the pulley body 612 to descend until the pulley body 612 contacts the ground. Since the force of manually turning the handle 64 is limited, in order to lift the base 1, it is necessary to use tools to assist the base 1 to support it, so as to facilitate the pulley body 612 to continue to descend until the base 1 is separated from the ground, and the device can be moved by the pulley body 612. At the same time, the handle 64 can also be replaced with a driving motor to drive the rotating shaft 65 to rotate. This adjustment method has a relatively high cost, but there is no need to assist the base 1.

When the lifting column 24 moves up and down, the limiting convex strip 22 will slide inside the strip groove 23, thereby avoiding the problem that the screw 25 drives the lifting column 24 to rotate synchronously;

[0063] S3: In order to facilitate the infrared sensor 517 to detect people in different directions, the motor 512 inside the mounting shell 511 is opened, and the motor 512 drives the driving shaft 513 to rotate through the output end, and the driving shaft 513 rotates to drive the fan gear 514, and the fan gear 514 rotates to drive the transmission gear 515 to rotate, and the transmission gear 515 rotates to drive the rotating rod 516 to rotate, and the rotating rod 516 rotates to drive the infrared sensor 517 to rotate, so as to monitor other directions.

[0068] The working principle and use process of the present invention: when the present invention is in use, when the device is moved, the handle 64 is turned, and the rotation of the handle 64 drives the rotating shaft 65 to rotate, and the rotation of the rotating shaft 65 drives the small gear 66 to rotate, and the small gear 66 drives the large gear 62 to rotate, and the rotation of the large gear 62 drives the threaded rod 69 to rotate, and the rotation of the threaded rod 69 drives the lifting plate 67 to descend. When the lifting plate 67 descends, it will slide on the surface of the guide rod 68, so as to improve the stability of the lifting plate 67 during the descent process. The descent of the lifting plate 67 drives the mounting plate 611 and the pulley body 612 to descend until the pulley body 612 contacts the ground.

The infrared sensor 517 monitors the dynamics in the warning area near the warning device. Once a person is detected to enter, the infrared sensor 517 will signal The signal is transmitted to the controller 57. After receiving the signal, the controller 57 converts the infrared signal into an electrical signal and transmits it to the relay 58.

At this time, the spring 532 rebounds, thereby driving the fixing rod 535 to insert into the fixing hole on the side of the card slot 52, so as to realize the installation of the heat dissipation fan body 54. At this time, the warning device can be cooled and cooled by the heat dissipation fan body 54.
