The auxiliary support rods 2 are retractable, and the bottom of the inner wall of the main frame 1 is rotatably provided with pulley rods 4. The auxiliary support rods 2 on both sides of the bottom of the main frame 1 provide support for the bottom of the guardrail to prevent the guardrail from tipping over after being stressed, thereby increasing the stability of the guardrail. The middle position of the bottom of the inner wall of the main frame 1 is fixedly connected to the bottom of the vertical support plate 3, and the T-shaped slide groove of the inner wall of the vertical support plate 3 is slidably connected to one end of the T-shaped slider 7, and the other end of the T-shaped slider 7 One end is fixedly connected to one side of the baffle plate 5, the top of the front side of the baffle plate 5 is fixedly connected to one end of the first fixed frame 8, and the other end of the first fixed frame 8 is rotatably connected to the bottom of the bottom power frame 6 through a rotating rod.

The number of T-shaped sliders 7 is four, and two T-shaped sliders 7 are symmetrically arranged on one side of the baffle plate 5 as a group. The T-shaped sliders 7 on both sides of the baffle plate 5 slide on the inner wall of the vertical support plate 3 to ensure that the baffle plate 5 can move vertically under force to avoid tilting during movement.

[0027] See also Figure 1 The top of the bottom power frame 6 is rotatably connected to the middle of the top power rod 18 through a rotating rod, one end of the top power rod 18 is fixedly sleeved with the outer circumferential surface of the left end of the rotating shaft 11, the left end of the rotating shaft 11 is rotatably connected to one end of the second fixed frame 17, the other end of the second fixed frame 17 is fixedly connected to the middle position of the top of the main frame 1, the end of the top power rod 18 away from the second fixed frame 17 is fixedly provided with an arc rod 9 through a connecting rod, the end of the arc rod 9 away from the top power rod 18 is fixedly provided with an anti-slip rod 13, the end of the anti-slip rod 13 is slidably plugged into the top of the top vertical plate 15 The bottom of the top vertical plate 15 is fixedly set on the top of the main frame 1. By setting the arc rod 9 at one end of the top power rod 18, the top power rod 18 drives the arc rod 9 and the anti-slip rod 13 to slide on the top of the top vertical plate 15 when it moves, thereby increasing the stability of the top power rod 18 during movement and preventing the top power rod 18 from causing deviation during movement. The arc rod 9 is concentrically arranged with the rotating shaft 11, and the thickness of the top power rod 18 at the bottom of the arc rod 9 is less than the thickness of the top inner wall of the bottom power frame 6, thereby avoiding movement conflict between the arc rod 9 and the top power plate 18 and the bottom power frame 6.

[0028] See also Figure 2An inner slide groove is provided in the middle of the baffle 5, and a top inner plate 19 is slidably provided on the inner wall of the inner slide groove. The top of the top inner plate 19 is fixedly provided on the top of the main frame 1. The thickness of the main frame 1 is smaller than the thickness of the inner slide groove in the middle of the baffle 5, which facilitates the top inner plate 19 to slide on the inner wall of the baffle 5 and facilitates the baffle 5 to move upward after being subjected to force.

[0029] See also Figure 4 The right end of the rotating shaft 11 is plugged into the middle of the worm wheel 10, and the worm wheel 10 is connected to the threaded transmission on one side of the outer circumference of the worm 12 through the teeth on one side of the outer circumference, and one end of the worm 12 is fixedly connected to the output shaft on one side of the motor 16 through a connecting rod.

The motor 16 provides power support for the worm wheel 10 and worm 12, while avoiding movement conflict between the worm wheel 10 and the main frame 1 during movement.

[0030] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer or the like.

[0031] The implementation principle of a guardrail for construction projects in an embodiment of the present application is as follows: the guardrail is placed around the construction site of the construction project, the lengths between the four auxiliary support rods 2 are adjusted according to the environment around the construction, and the four auxiliary support rods 2 are used to provide auxiliary support for the guardrail, thereby increasing the stability of the guardrail. When it is necessary to transport materials to the inside of the guardrail, the motor 16 is started as a power to drive the worm gear 10 and the worm 12 to rotate, so that the rotating shaft 11 drives the top power rod 18 to swing in an arc, and the top power rod 18 pulls up the baffle 5 through the bottom power frame 6, prompting the bottom of the guardrail to open a hole, so as to facilitate the transportation of materials from the upper surface of the pulley rod 4 at the bottom. Under the action of the pulley rod 4, the material can slide toward the temple more easily.
