Description

Technical Field

[0001] The utility model relates to the field of construction engineering, in particular to a safety guardrail. Background Art

[0002] Construction engineering refers to the engineering entity formed by the construction of various housing buildings and their ancillary facilities and the installation of supporting lines, pipelines and equipment.

[0003] After retrieving the patent document with the publication number of CN220979066U, this patent document discloses "a safety guardrail for construction engineering management. This device pastes a reflective film on the inclined surface, and when the vehicle turns on the lights at night, it can immediately receive the reflective feedback, realize the danger and do not approach. And in the construction site, many pedestrians and non-motor vehicles often move along the safety guardrail. The upper rounded corner of the protruding plate is set to prevent such pedestrians from being bruised and prevent the sharp corner from catching clothes."

[0004] The safety guardrail for construction engineering is generally installed on the outer circle of the construction site, and there is generally a large amount of dust near the construction site. In order to avoid the influence of this dust on the surrounding pedestrians, the periphery of the construction site is generally sprinkled regularly, so as to reduce the influence of dust on pedestrians. After a long time, it is easy to cause a lot of dust to adhere to the reflective film on the lower shell of the above device, thus affecting the reflective effect of the reflective film.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0027] The present utility model will be further described below with reference to the drawings:

[0028] As Figures 1-6As shown in the figure, a safety guardrail includes two bottom plates 1. A protection mechanism is installed at the upper end of the bottom plate 1, and a warning mechanism is also included.

[0029] A plurality of spikes 11 are provided on both of the two bottom plates 1; the device can be fixed by driving the spikes 11 into the ground.

[0030] The protection mechanism includes a porous double-layer plate frame 2. The porous double-layer plate frame 2 is arranged at the upper end of the bottom plate 1. L-shaped fixing frames 21 are arranged at the front and rear ends of the porous double-layer plate frame 2 corresponding to the positions of the two bottom plates 1. Reflective stickers 22 are fixed on the outer walls of the front and rear ends of the porous double-layer plate frame 2. A porous single-layer plate 23 is slidably connected inside the porous double-layer plate frame 2. A plurality of ventilation holes are provided on both the porous double-layer plate frame 2 and the porous single-layer plate 23, and the positions of the ventilation holes on the porous double-layer plate frame 2 and the porous single-layer plate 23 correspond to each other. A pull handle 24 is fixed at the upper end of the porous single-layer plate 23. On one side of the front end of the porous double-layer plate frame 2, there is a three-rod limit frame 25. The three-rod limit frame 25 is composed of three threaded-head insertion rods and the plate structure at the front end of the threaded-head insertion rods. Through holes are provided at one end of the porous single-layer plate 23 and both ends of the porous double-layer plate frame 2 corresponding to the three threaded-head insertion rods of the three-rod limit frame 25, and the size of the through holes is the same as that of the ventilation holes. Nuts 26 are threadedly connected to the three threaded-head insertion rods of the three-rod limit frame 25; after unscrewing the three nuts 26 on the three-rod limit frame 25 and pulling out the three-rod limit frame 25, due to the sliding connection between the porous single-layer plate 23 and the porous double-layer plate frame 2, pulling the pull handle 24 can move the porous single-layer plate 23. Then, insert the three-rod limit frame 25 into the through hole corresponding to the other end of the porous double-layer plate frame 2, so that the porous single-layer plate 23 is limited again. In this way, the ventilation holes of the porous single-layer plate 23 are blocked by the porous double-layer plate frame 2, and the ventilation holes of the porous double-layer plate frame 2 are blocked by the porous single-layer plate 23. Through such adjustment, the applicability of the device is better.

[0031] The warning mechanism includes an upper extension frame 3, which is fixed to the upper end of the porous double-layer plate frame 2. A double-layer mounting frame 31 is fixed to the upper end of the upper extension frame 3. A motor 32 is installed at the bottom layer of the double-layer mounting frame 31. A warning light 33 is installed at the top end of the upper layer of the motor 32. The light of the warning light 33 is red, and the lower end of the lampshade of the warning light 33 is semicircular. Two brush sweeping frames 34 are fixed to the output end of the motor 32. The brush sweeping frames 34 are provided with a curvature corresponding to the lampshade of the warning light 33, and the inner wall of the brush sweeping frames 34 fits with the lampshade of the warning light 33. A light-shielding plate 35 is fixed to the outer wall of the brush sweeping frames 34. The size of the light-shielding plate 35 is larger than that of the brush sweeping frames 34, and the light-shielding plate 35 and the brush sweeping frames 34 are provided with the same curvature. At night, after turning on the warning light 33, the warning light 33 can emit red light to warn passing vehicles. When the warning light 33 is turned on, the motor 32 is started at the same time. The motor 32 will drive the two brush sweeping frames 34 and the light-shielding plate 35 at its output end to rotate around the warning light 33, so that the brush sweeping frames 34 can sweep off the dust adhered to the lampshade of the warning light 33, so as to avoid the influence of more adhered dust on the warning effect brought by the red light. And through the setting of the two light-shielding plates 35, when the light-shielding plates 35 rotate with the brush sweeping frames 34, they will have a flashing effect on the red light emitted by the warning light 33, making the warning effect better in this way.

[0032] Working principle: When installing the device, first adjust the device according to the ventilation conditions required on the construction site. After unscrewing the three nuts 26 on the three-rod limiting frame 25 and pulling out the three-rod limiting frame 25, through the sliding connection between the porous single-layer plate 23 and the porous double-layer plate frame 2, pulling the handle 24 can move the porous single-layer plate 23. Then insert the three-rod limiting frame 25 into the through holes at the other end of the porous double-layer plate frame 2 to limit the porous single-layer plate 23. In this way, the ventilation holes of the porous single-layer plate 23 are blocked by the porous double-layer plate frame 2, and the ventilation holes of the porous double-layer plate frame 2 are blocked by the porous single-layer plate 23. Through such adjustment, the applicability of the device is better. When the device is used at night, after turning on the warning light 33, the warning light 33 can emit red light to warn passing vehicles. When the warning light 33 is turned on, the motor 32 is started at the same time. The motor 32 will drive the two brush sweeping frames 34 and the light-shielding plate 35 at its output end to rotate around the warning light 33, so that the brush sweeping frames 34 can sweep off the dust adhered to the lampshade of the warning light 33, so as to avoid the influence of more adhered dust on the warning effect brought by the red light. And through the setting of the two light-shielding plates 35, when the light-shielding plates 35 rotate with the brush sweeping frames 34, they will have a flashing effect on the red light emitted by the warning light 33, making the warning effect better in this way.
