Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a three-fold horizontal protection for elevator shafts. Background Technology

[0002] An elevator shaft is a vertical passage used to install elevators, guiding and supporting the elevator car and related mechanical equipment. During construction, horizontal protection is often used to prevent dust, debris, and external objects from entering the shaft and to protect the normal operation of the equipment. Horizontal protection also prevents potential falls during construction, ensures the safety of construction workers, maintains the stability of the structure, and ensures the overall safety of the construction site.

[0003] However, traditional elevator shaft protection measures mostly use fixed single protective panels, whose shape and size are relatively fixed, making it difficult to flexibly adapt to elevator shafts of different specifications. If ordinary multi-piece splicing protective devices are used, although the applicability is improved to a certain extent, problems such as loosening and displacement of the splicing parts are prone to occur, affecting the stability and safety of the overall structure. At the same time, there may also be splicing gaps, resulting in inadequate protection and certain safety hazards.

[0004] Therefore, this utility model provides a three-fold horizontal protection for elevator shafts to solve the above problems. Utility Model Content

[0009] As a preferred technical solution of this application, both the first protective plate and the second protective plate are made of steel mesh. The four corners of the first upper steel plate and the first lower steel plate, as well as the second upper steel plate and the second lower steel plate, are connected by threaded bolts.

The first upper steel plate 1 and the second upper steel plate 6 are connected by the hinges 2 to realize the folding function, so that the unfolded state and coverage can be flexibly adjusted according to actual needs, making it more adaptable and the installation process simple and quick. At the same time, this three-plate folding structure can form a relatively complete and continuous protective surface after unfolding, effectively eliminating the safety hazards caused by traditional splicing gaps.

[0024] The mainboard assembly includes a first protective rod 3, the upper surface of which overlaps the lower surface of the first upper steel plate 1.

The first upper steel plate 1 and the first lower steel plate 5 clamp and fix the first protective plate 4. The first protective rod 3 limits the first protective plate 4 to prevent slippage, thereby allowing the first protective plate 4 to be installed and fixed. The operation is convenient and facilitates daily maintenance and replacement of the first protective plate 4. At the same time, the first upper steel plate 1 and the first lower steel plate 5 help to enhance the overall strength and impact resistance of the first protective plate 4.

[0025] The wing plate assembly includes a second upper steel plate 6. One side of the upper surface of the second upper steel plate 6 is fixedly connected to one side of the lower surface of the hinge 2. A second protective rod 7 overlaps the lower surface of the second upper steel plate 6. A second protective plate 8 is sleeved on the outer surface of the second protective rod 7.

The second upper steel plate 6 and the second lower steel plate 9 can clamp and fix the second protective plate 8. The second protective rod 7 prevents the second protective plate 8 from slipping, thus allowing the second protective plate 8 to be installed and fixed. The operation is convenient, and it is easy to disassemble, maintain and replace the second protective plate 8. At the same time, the second upper steel plate 6 and the second lower steel plate 9 help to enhance the overall strength and impact resistance of the second protective plate 8.

[0026] The first protective plate 4 and the second protective plate 8 are both made of steel mesh. The four corners of the first upper steel plate 1 and the first lower steel plate 5, as well as the second upper steel plate 6 and the second lower steel plate 9, are all connected by connecting bolts 10.

By positioning the limiting beam 14 horizontally at the elevator shaft opening, the installation can be completed quickly, making the installation process simpler and faster.

[0028] The front surface of the connecting block 13 is threaded with a first fixing bolt 15. One end of the outer surface of the first fixing bolt 15 is threaded to the front surface of the limiting beam 14. The first fixing bolt 15 facilitates the fixing of the connecting block 13 and the limiting beam 14, thereby fixing the position of the connecting block 13 on the outer surface of the limiting beam 14.

[0029] The upper surface of the connecting block 13 is threaded with a second fixing bolt 16. The bottom end of the outer surface of the second fixing bolt 16 is threaded to one end of the upper surface of the cantilever beam 12. The second fixing bolt 16 facilitates the connection and fixation of the connecting block 13 and the cantilever beam 12, so as to facilitate the connection and fixation of the cantilever beam 12 and the limiting beam 14.

[0030] Working steps: First, the connecting block 13 and the cantilever beam 12 are connected and fixed by the second fixing bolt 16. Then, the connecting block 13 and the limiting beam 14 are fixed by the first fixing bolt 15. Next, one end of the cantilever beam 12 is embedded in the elevator shaft wall. Then, the limiting beam 14 is horizontally placed at the elevator shaft opening for locking. Next, the second upper steel plates 6 on both sides of the first upper steel plate 1 are unfolded to both sides by the hinge 2. The first protective plate 4 and the second protective plate 8 can provide horizontal protection for the elevator shaft. Finally, the connecting bolt 10 can be pulled out by unscrewing the fastening nut 11.
