[0005] A quick-installation and dismantling elevator shaft horizontal protection device includes a central frame, with side frames on both sides of the central frame. Both the central frame and the side frames have rectangular frames, and the frames are connected with horizontal and vertical square tubes to form a grid-like internal structure. One side of the central frame has a connecting part for supporting the floor slab at the end of the elevator shaft. A wall-clamping square tube is installed on the upper side of the connecting part for clamping onto the walls on both sides of the elevator shaft doorway.

[0006] A first tripod is fixed on the other side of the central frame, and a second tripod is fixed on the corresponding side of the side frame. Both the first and second tripods are set perpendicular to the corresponding frame. The top of the first and second tripods are provided with insertion holes for inserting round steel and extending to the drawing die hole.

[0007] The side frames and the adjacent frames of the central frame are hinged together.

[0008] Furthermore, the connecting part includes multiple supporting square tubes extending along the length direction of the central frame, with one end of the supporting square tube welded to the end side of the central frame and the other end welded to the same transverse square tube.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] like Figure 1-2As shown: A quick-installation and dismantling elevator shaft horizontal protection device includes a central frame 1, with side frames 2 on both sides of the central frame 1. Both the central frame 1 and the side frames 2 have rectangular frames 21, and the frames 21 are connected with horizontal and vertical square tubes to form a grid-like internal structure. The central frame and the side frames are both welded from square tubes with a cross-sectional size of 30mm x 30mm. The size of the central frame is adjustable and made according to the size of the elevator shaft door opening. Generally, the door opening is 1000mm wide, and the rectangular frame is 800mm wide, which can be easily inserted into the door opening. The length is 2530mm.

[0025] The side frame dimensions are 700mm x 2200mm.

[0026] The central frame 1 has a connecting part on one side for support to the floor slab at the end of the elevator shaft. A wall-clamping square tube 3 is installed on the upper side of the connecting part to clamp onto the walls on both sides of the elevator shaft door opening; this clamps the central frame and prevents it from tilting. The wall-clamping square tube is a single stainless steel square tube with a cross-sectional dimension of 100mm x 100mm and a length of 1600mm, used to clamp onto the walls on both sides of the elevator shaft door opening.

[0027] A first tripod 4 is fixed on the other side of the central frame 1, and a second tripod 5 is fixed on the corresponding side of the side frame 2. The first tripod 4 and the second tripod 5 are both set perpendicular to the corresponding frame 21. The top of the first tripod 4 and the second tripod 5 are provided with insertion holes for inserting round steel 41 and extending to the drawing hole.

[0028] The round steel has a diameter of 24mm and a length of 300mm, and the central frame is supported on the concrete wall of the elevator shaft.

[0029] The side frame 2 and the adjacent frame 21 of the central frame 1 are hinged together by hinges 6. The hinges are heavy-duty hinges, and multiple hinges are evenly distributed on one side of the central frame.

[0030] Due to the limited space in the elevator shaft doorway, it's impossible to move the fully deployed protective device into the shaft. Therefore, the central and side frames are hinged together. The side frames can be flipped to be perpendicular to the side of the central frame, reducing the overall width and allowing for easy passage through the doorway. Supported by the connecting parts to the floor slab, the other side of the central frame is positioned and supported by round steel inserted through the first triangular bracket's positioning hole. Then, the side frames on both sides are opened, flipped to a horizontal position with the central and side frames, and positioned and fixed through the second triangular bracket's insertion hole. This completes the unfolding process within the elevator shaft, forming a complete protective support.

[0031] like Figure 3As shown: The connecting part includes multiple supporting square tubes 11 extending along the length of the central frame 1. One end of each supporting square tube 11 is welded to the end side of the central frame 1, and the other end is welded to the same horizontal square tube 12. The supporting square tubes are 300mm long, with the bottom used for support on the floor slab and the upper side secured by wall-clamping square tubes. Multiple longitudinal square tubes 13 are vertically fixed to the upper end of the horizontal square tubes 12 for positioning the wall-clamping square tubes 3, thus improving the installation stability of the wall-clamping square tubes.

[0032] like Figure 2 As shown: Multiple bottom square tubes 14 are welded to the bottom of the central frame 1. The bottom square tubes 14 extend along the width direction of the central frame 1 and their ends extend beyond the sides of the central frame 1, serving to support the side frames 2 in the open state. There are three bottom square tubes, which coincide with the longitudinal position of the square tubes inside the central frame.

[0033] like Figure 3 As shown: The second tripod 5 is movably fitted with the corresponding side frame 2. A sleeve 51 is fixed between the connection between the second tripod 5 and the corresponding frame 21, which is used to fit the frame of the side frame 2 and slide along the width direction for width adjustment. This is used to adjust the position of the tripod insertion hole to align with the grinding hole, preventing the round steel from being unable to be inserted into the grinding hole due to inaccurate hole positioning.

[0034] Before construction, ensure safety measures are in place, wear safety gear, and conduct a safety briefing. Insert the round steel bars into the tripod of the central frame. Use weights and hinges to install the side frames onto the central frame. After installation, the protective frame should be folded. Align the round steel bars of the central frame with the bottom formwork holes of the elevator shaft concrete wall and insert them into the formwork holes, with the other end resting on the floor slab. Use square tubing to secure the central frame to the walls on both sides of the elevator shaft doorway. Finally, open the side frames to a horizontal position and insert the round steel bars into the bottom formwork holes of the concrete wall. Place steel mesh (not shown in the diagram) to form a horizontal protective structure for quick installation and removal of the elevator shaft using the formwork holes.

[0035] During dismantling, first remove the steel mesh panels. Pull out the round steel bars that are inserted into the walls on both sides of the frame, and fold the side frames into a closed state. Remove the square tubes that are holding the walls in place, and finally pull out the central frame to complete the quick dismantling.

[0036] These embodiments are selected and specifically described in this specification in order to better explain the principles and practical applications of this utility model, so that those skilled in the art can better understand and utilize this utility model.
