Description

Technical Field

[0001] The utility model relates to the technical field of elevator shaft protection, in particular to a protection structure for elevator shafts in building construction. Background Technique

[0002] The elevator shaft is an essential facility in high-rise buildings. The size of the main shaft is determined according to the elevator type selection. Elevator tracks and counterweight tracks are installed on the shaft wall. The reserved door opening is also called the main shaft opening of the elevator shaft, which is used to install elevator doors. There is an elevator machine room at the top of the shaft. There are great safety threats during the construction of the elevator shaft. If it is not protected, the risk of falling is likely to occur. Therefore, it is necessary to carry out special protection at the wellhead through a special protection device to reduce potential safety hazards.

[0003] Most of the existing protection structures fix a protection board at the wellhead of the elevator shaft through bolts. The size of the protection board is basically fixed, resulting in that the protection board cannot be suitable for elevator wellheads of different sizes and specifications. Moreover, most of the existing protections for elevator wellheads and the interior of elevator shafts are installed separately, which is rather troublesome to install.

[0004] Therefore, the utility model provides a protection structure for elevator shafts in building construction. Content of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a protection structure for elevator shafts in building construction to solve the problems raised in the above background technique. The utility model can form a double-layer protection through the first protection net and the second protection net to ensure the protection effect, and can simultaneously protect the elevator shaft and the elevator wellhead; the length of the device can also be extended, so that the device is suitable for elevator shafts of different sizes.

[0006] To achieve the above purpose, the utility model is realized through the following technical solutions: A protection structure for elevator shafts in building construction includes two slide rails fixed on one side of the elevator wellhead. A frame is installed between the upper and lower slide rails. A first protection net and a second protection net are installed in the frame. A plurality of first hooks are installed in the frame, and the first hooks correspond to the first protection net. The frame is rotatably connected to the second protection net. A locking structure is installed on one side of the frame, and the locking structure corresponds to the second protection net. Extension structures are installed on both sides of the frame.

[0007] Furthermore, sliders are fixed on both the upper and lower sides of the frame, and the sliders correspond to the slide rails.

[0008] Furthermore, the extension structure includes a plurality of second hooks, which are respectively fixed on the peripheral side of the frame. Screws are in threaded fit at both ends of the slider, and an auxiliary hanging net is installed between the second hook and the screw.

[0009] Furthermore, a positioning rod is rotatably fitted on the screw rod, and the outer periphery of the positioning rod has an L-shaped structure.

[0010] Furthermore, a through groove is formed in the frame, and the first hooks are fixed at the four corners inside the through groove, and both the first protective net and the second protective net are located inside the through groove.

[0011] Furthermore, a rotating shaft is rotatably fitted inside the through groove, and the rotating shaft is fixedly connected to the second protective net.

[0012] Furthermore, the locking structure includes a threaded head and a nut. One end of the rotating shaft is fixedly connected to the threaded head, and the nut corresponds to the threaded head.

[0013] Furthermore, the threaded head is rotatably connected to the frame, and a turning handle is fixed at one end of the threaded head.

[0014] The beneficial effects of the present utility model: A building construction elevator shaft protection structure of the present utility model includes a frame; a first protective net; a second protective net; and an extension structure.

[0015] By installing the first protective net and the second protective net inside the frame, a double-layer protection can be formed through the first protective net and the second protective net to ensure the protection effect, and the second protective net can be rotated so that the second protective net rotates into the elevator shaft, thereby realizing the protection of both the elevator shaft and the elevator shaft opening at the same time. By installing the extension structure on both sides of the frame, the length of the device can be extended, so that the device is suitable for elevator shafts of different sizes.

[0023] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0024] Please refer to Figures 1 to 6 , the present utility model provides a technical solution: a protection structure for a building construction elevator shaft, including two slide rails 1 fixed on one side of the elevator shaft opening, a frame 2 is installed between the upper and lower two slide rails 1, a first protective net 7 and a second protective net 8 are installed in the frame 2, a plurality of first hooks 4 are installed in the frame 2, the first hooks 4 correspond to the first protective net 7, the frame 2 is rotatably connected to the second protective net 8, a locking structure is installed on one side of the frame 2, the locking structure corresponds to the second protective net 8, and extension structures are installed on both sides of the frame 2.

[0025] In this embodiment, sliders 14 are fixed on both the upper and lower sides of the frame 2, the sliders 14 correspond to the slide rails 1. Specifically, the frame 2 can slide in the slide rails 1 through the sliders 14, so as to open or close the elevator shaft opening.

[0026] The extension structure includes a plurality of second hooks 5, the plurality of second hooks 5 are respectively fixed on the periphery of the frame 2, screw rods 6 are in threaded fit with both ends of the slider 14, and auxiliary hanging nets are installed between the second hooks 5 and the screw rods 6.

[0027] Specifically, when it is necessary to extend the length of the device, the screw rod 6 can be rotated so that the screw rod 6 rotates out of the slider 14, and then the auxiliary hanging net is hung on the screw rod 6 and the second hook 5, so as to add auxiliary hanging nets on both sides of the frame 2, and the length of the device can be extended.

[0028] A positioning rod 13 is rotatably fitted on the screw rod 6, and the periphery of the positioning rod 13 is of an L-shaped structure.

[0029] Specifically, when it is necessary to fix the position of the frame 2, the screw rod 6 can be rotated so that the positioning rod 13 moves until the positioning rod 13 contacts the inner wall of the elevator shaft opening, so that the frame 2 can be limited in the elevator shaft opening.

[0030] A through slot 3 is provided in the frame 2. The first hooks 4 are fixed at the four corners inside the through slot 3. Both the first protective net 7 and the second protective net 8 are located inside the through slot 3. A rotating shaft 9 is rotatably fitted inside the through slot 3.
