Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering auxiliary equipment, in particular to an elevator opening safety protection device. Background Art

[0002] At present, with the development of economy, more and more high-rise buildings are being built, and the demand for elevators is also growing. The protection of elevator entrances is the focus of safety management in construction projects. During the installation of elevators, the construction site is generally an unfinished construction site. Therefore, there are no safety devices on each floor. Sometimes only some simple iron pipes or gauze are used for protection, which is not only unreliable but also easy to be taken away by others, causing safety hazards.

[0003] In many housing construction projects, elevator openings are high-incidence points for fall accidents, and the protection of elevator vertical openings is the focus of safety management. At present, scaffolding pipes + dense mesh or thin plates + implanted expansion bolts are more commonly used. The protection effect is low, the fixing procedures are cumbersome or the turnover rate is not high, resulting in low standardization of civilized construction and increased costs. The traditional way to protect elevator openings is to set finished doors made of steel bars or square tubes at the openings. When installing the finished doors, it is necessary to use tools to drill holes in the shear walls on both sides of the opening, and then fix the finished doors to the shear walls with bolts and other objects. This will not only damage the wall and cause material waste, but also at different construction stages, the protective device needs to be removed or installed. At this time, the bolts and other objects need to be removed, which is not only complicated, but also has certain losses. Utility Model Content

[0021] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0022] like Figures 1 to 5 As shown, an elevator entrance safety protection device includes a skeleton 2 and a steel rod 10, both ends of the skeleton 2 are connected with outer fixed angle steels 4, one side of the skeleton 2 is paved with a protection panel 1, and the other side is provided with a double-headed "L" screw 6, one end of the double-headed "L" screw 6 is screwed with a nut A5, and the other end is screwed with a nut B11, the nut A5 is fixed on the skeleton 2, the nut B11 is connected to one end of a rotating steel plate 7, the other end of the rotating steel plate 7 is connected to a nut C12, the nut C12 is connected to one end of a single-headed "L" screw 8, the other end of the single-headed "L" screw 8 is connected to an inner fixed steel plate 9, a through hole 13 is provided at the center of the rotating steel plate 7, the through hole 13 corresponds to the steel rod 10, and the outer fixed angle steel 4 is arranged opposite to the inner fixed steel plate 9.

[0023] The protective panel 1 is provided with a square hole 3, which is convenient for an arm to extend into to adjust the rotating steel plate 7.

[0024] The threaded end of the single-thread "L" screw 8 is screwed into the nut C12.

[0025] The nut B11 and the nut C12 are both arranged on the same side of the rotating steel plate 7 .

[0026] The single-thread "L" screw 8 is connected to the inner fixed steel plate 9 by welding, the frame 2 is connected to the protective panel 1, the outer fixed angle steel 4 and the nut A5 by welding, and the rotating steel plate 7 is connected to the nut B11 and the nut C12 by welding.

[0027] One end of the double-thread "L" screw 6 is screwed into the nut A5, and the nut A5 is welded to the frame 2. The other end of the double-thread "L" screw 6 is screwed into the nut B11 (rotate the rotating steel plate 7 to screw the nut B11 into the double-thread "L" screw 6), thereby connecting one end of the rotating steel plate 7 to the double-thread "L" screw 6, and the threaded end of the single-thread "L" screw 8 is screwed into the nut B12 (rotate the single-thread "L" screw 8 to screw it into the nut B12), thereby connecting the other end of the rotating steel plate 7 to the single-thread "L" screw 8, place the frame 2 in the elevator hole, and make the outer fixed angle steel 4 contact with one side of the wall 14, and the inner fixed steel plate contact with the other side of the wall 14. Surface contact, the steel rod 10 is inserted into the through hole 13, and the rotating steel plate 17 is rotated clockwise by the steel rod 10. Under the corresponding rotation of the screw and the nut, the distance between the nut B11 and the nut C12 is reduced, thereby reducing the distance between the outer fixed angle steel 4 and the inner fixed steel plate 9, until the outer fixed angle steel 4 and the inner fixed steel plate 9 clamp the wall 14. Dismantling type, the rotating steel plate 17 is rotated counterclockwise by the steel rod 10 to increase the distance between the nut B11 and the nut C12, thereby loosening the outer fixed angle steel 4 and the inner fixed steel plate 9 to clamp the wall 14, and then take out the entire device, and disassemble the rotating steel plate 7, the single-head wire "L" screw 8 and the double-head wire "L" screw 6 for easy packaging and transportation.
