[0021] like Figures 1 to 5 As shown, an integrated fixing device for vertical and horizontal protection of an elevator shaft comprises a vertical guardrail 1, a movable guard frame, a telescopic main guard frame 3, a folding guard frame and a steel wire rope 5; the vertical guardrail 1 is fixed at the elevator shaft opening; the movable guard frame comprises a movable main guard frame 2.1, a movable left guard frame 2.2 and a movable right guard frame 2.3, the end of the movable main guard frame 2.1 is rotatably connected to the bottom end of the vertical guardrail 1, and the movable left guard frame 2.2 and the movable right guard frame 2.3 are respectively rotatably connected to the left and right sides of the movable main guard frame 2.1 through hinges; the telescopic main guard frame 3 is slidably connected to the movable main guard frame 2.1 The inner cavity at the front of the protective frame 2.1 and the relative position between the two can be fixed by the locking bolt 6; the folding protective frame includes a folding main protective frame 4.1, a folding left protective frame 4.2 and a folding right protective frame 4.3, the end of the folding main protective frame 4.1 is connected to the upper front end of the movable main protective frame 2.1 through a hinge and avoids the telescopic main protective frame 3. The folding left protective frame 4.2 and the folding right protective frame 4.3 are respectively connected to the left and right sides of the folding main protective frame 4.1 through a hinge; the lifting ring 7 at the front end of the telescopic main protective frame 3 is connected to the upper end of the vertical protective railing 1 through a wire rope 5.

[0022] In this embodiment, the movable protection frame, the telescopic main protection frame 3 and the folding protection frame are all provided with steel mesh 8. The bottom of the vertical protection railing 1 is provided with a footboard 12 painted with red and yellow reflective paint. The fixed shafts 10 on both sides of the upper end of the vertical protection railing 1 are fixed to the side walls at the elevator shaft opening through U-shaped clips, and the fixed bottom plates 11 on both sides of the lower end of the vertical protection railing 1 are anchored to the bottom plate of the elevator shaft opening through anchor bolts.

[0023] A fixed top foot device 9 is connected between the vertical guardrail 1 and the movable main guard frame 2.1. The fixed top foot device 9 is L-shaped, one end of the fixed top foot device 9 is fixedly connected to the vertical guardrail 1, and the other end is rotatably connected to the movable main guard frame 2.1.

[0024] Specific steps:

[0025] 1. Determine whether it is necessary to open the telescopic main protection frame 3 according to the size of the elevator shaft. If the length of the elevator shaft is greater than 1.8 meters, the telescopic main protection frame 3 needs to be opened. Fix the movable main protection frame 2.1 and the telescopic main protection frame 3 by locking bolts 6 to meet the size requirements.

[0026] 2. Fix the vertical guardrail 1 to the elevator shaft opening, fix the upper fixed shaft 10 by a U-shaped clip, and fix the lower fixed base plate 11 by expansion bolts. The fixed top foot device 9 can prevent the horizontal protection from slipping.

[0027] 3. After the vertical guardrail 1 is fixed, fix the wire rope 5 on the lifting ring 7 and slowly lower it into the elevator shaft at an angle greater than 15° to prevent the horizontal guardrail from slipping.

[0028] 4. After the telescopic main protective frame 3 is placed, first open the folding main protective frame 4.1, then open the folding left and right protective frames in sequence, and finally open the movable left and right protective frames in sequence.

[0029] 5. The steel mesh 8 and the protection frame are integrated. If they need to be dismantled, first fold up the movable left and right protection frames, then fold up the folding left and right protection frames, and finally fold up the folding main protection frame 4.1.

[0030] 6. Pull up the telescopic main protection frame 3 to a position parallel to the vertical protection railing 1 through the wire rope 5, and then retract the telescopic main protection frame 3 into the movable main protection frame 2.1 by loosening the locking bolts 6, and fix the vertical protection railing 1 and the movable main protection frame 2.1 through the lifting ring 7 and the wire rope 5 to prevent them from spreading.

[0031] 7. Remove the expansion bolts that fix the bottom plate 11, and finally remove the U-shaped clip that fixes the upper end of the shaft 10, and remove the vertical and horizontal integrated protection fixing device.

[0032] This device can protect elevator shafts of different sizes by adjusting the telescopic main protection frame. It can be folded and unfolded through hinges, occupying a small space. It can be disassembled and assembled through the bolts of the fixed top foot device. When it needs to be installed and removed, it can be operated by retracting and releasing the lifting ring and wire rope, which is convenient to use and improves work efficiency. It can effectively protect people, gravel, square wood, templates, and debris in the upper elevator shaft from falling. A 20CM footboard is welded at the bottom of the vertical guardrail, and the outer side is painted with red and yellow reflective paint to protect the floor garbage from falling into the elevator shaft and serve as a safety warning. This device is sprayed with anti-corrosion and anti-rust paint. The fixed top foot device can prevent horizontal protection from slipping. The movable main protection frame and the folding main protection frame are fixedly connected by hinges, so that they can be opened and closed easily. The movable protection frame can increase horizontal support, greatly improving safety and reliability.

[0033] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model shall be based on the protection scope of the claims.
