[0033] Embodiment 1

[0034] This embodiment proposes an elevator opening protection method, mainly using an elevator opening protection device for construction. As Figure 1 shown, the elevator opening protection device includes a lower protection frame 1, and an upper protection frame 2 is slidably connected inside the lower protection frame 1. There are two lower protection frames 1 and two upper protection frames 2, and the two lower protection frames 1 and the two upper protection frames 2 form a shape like the Chinese character "ri" (日). Expansion joints 3 are provided at the joints between the two lower protection frames 1, at the joints between the lower protection frame 1 and the upper protection frame 2, and at the joints between the two upper protection frames 2.

[0035] The expansion joints 3 are used to achieve the expansion and contraction of the lower protection frame 1 and the upper protection frame 2, so as to adapt to the size of the elevator opening. There is no need to cut off steel pipes to meet the construction requirements, or use a whole piece of standardized protective railing, which reduces costs.

[0036] A protective net winding bin 6 is fixedly installed on the back of the protective lower frame 1, and a protective net is wound inside the protective net winding bin 6. Supporting feet 4 are fixedly installed on the bottom of the protective lower frame 1 and the top of the protective upper frame 2. The protective lower frame 1 and the protective upper frame 2 are supported at the elevator opening by the supporting feet 4 at the bottom and the supporting feet 4 at the top of the protective upper frame 2 to fix the positions of the protective lower frame 1 and the protective upper frame 2. The protective lower frame 1 and the protective upper frame 2 are extended and retracted to make the sun-shaped shape formed by the protective lower frame 1 and the protective upper frame 2 fit the elevator opening.

[0037] In this embodiment, the telescopic device 3 is used to achieve the telescopic movement of the protective lower frame 1 and the protective upper frame 2, so as to adapt to the size of the elevator opening. There is no need to cut the steel pipe to meet the construction requirements, or to use a whole piece of standardized protective railing to reduce costs. The supporting feet 4 are used to support and position the protective lower frame 1 and the protective upper frame 2 at the elevator opening, thereby improving the installation stability of the protective lower frame 1 and the protective upper frame 2.

[0038] Example 2

[0039] Based on Example 1, this example proposes an elevator opening protection method, such as Figure 2-Figure 5 As shown, the telescope 3 includes a support member, a swivel column 36, a ring 39, an extrusion plate 311 and a threaded slider 310. A support member is arranged between the two protective upper frames 2. The support member includes a support block 31, a center block 32, a pressure ring 37 and a linkage rod 38. The center block 32 is fixedly installed in the middle of the support block 31. The inner part of the center block 32 is slidably connected to the pressure ring 37. The pressure ring 37 is hinged to the ring 39 through the linkage rod 38. The ring 39 slides on the rotating shaft at the end of the swivel column 36. The protective upper frame 2 is slidably connected to the support block 31.

[0040] The internal sliding connection of the rotary column 36 is the threaded slider 310, and the internal sliding connection of the rotary column 36 is the extrusion plate 311, the extrusion plate 311 is in contact with the threaded slider 310, and the end of the extrusion plate 311 is rotatably connected to the mounting ring 39, the rotary column 36 extends to the interior of the protective upper frame 2, and the threaded slider 310 is threadedly connected to the protective upper frame 2.

[0041] A magnet is fixedly installed at the center of the rotating post 36 and near the threaded slider 310. When the threaded slider 310 is not subjected to external force, the threaded slider 310 is attracted by the magnet at the center of the rotating post 36 and adsorbed on the rotating post 36. At this time, the threaded slider 310 is received in the rotating post 36, and the protective upper frame 2 can slide on the rotating post 36 quickly.

[0042] The threaded slider 310 slides radially along the rotary column 36, and the extrusion plate 311 slides axially along the rotary column 36. The ends of the threaded slider 310 and the extrusion plate 311 are both provided with inclined surfaces. By pushing the pressure ring 37, the linkage rod 38 pushes the circular ring 39. The circular ring 39 pushes the extrusion plate 311 to push the threaded slider 310 outward using the inclined surface, so that the threaded slider 310 engages with the protective upper frame 2, thereby quickly retracting the protective upper frame 2 to roughly adapt to the elevator opening. At this time, there is a gap between the protective lower frame 1 and the protective upper frame 2 and the elevator opening, and the stability is poor.

[0043] The center block 32 is internally connected to a knob 33 for rotation, and the knob 33 is fixedly connected to a first bevel gear 34 via a rotating shaft. The end of the rotary column 36 is fixedly connected to a second bevel gear 35 via a rotating shaft, and the first bevel gear 34 is meshed with the second bevel gear 35. Since the threaded slider 310 is threadedly connected to the protective upper frame 2, the first bevel gear 34 is rotated by rotating the knob 33, and the rotation of the first bevel gear 34 causes the second bevel gear 35 to drive the rotary column 36 to rotate, so that the protective upper frame 2 moves with the rotation of the threaded slider 310, and the rotation of the threaded slider 310 drives the protective upper frame 2 to make fine adjustments, so that the protective lower frame 1 and the protective upper frame 2 are fully adapted to the elevator opening, thereby improving the installation stability.

[0044] When the positions of the lower protective frame 1 and the upper protective frame 2 are fixed directly by means of the plug rod and the plug hole, only fixed gear adjustment can be performed, while stepless adjustment can be performed by rotating the threaded slider 310. When a wide range of adjustment is required, the threaded slider 310 is sucked into the rotary column 36, and the upper protective frame 2 can be directly pulled for rough adjustment. When fine adjustment is required, the threaded slider 310 is squeezed out to be threadedly connected with the upper protective frame 2, so that stepless adjustment can be performed to fully adapt to the elevator opening.

[0045] In this embodiment, when the protective lower frame 1 and the protective upper frame 2 need to be adjusted, the threaded slider 310 is sucked into the interior of the rotary column 36 through the internal magnet of the rotary column 36, and the protective upper frame 2 can be quickly slid for rough adjustment. Subsequently, the threaded slider 310 is threadedly connected to the protective upper frame 2 by sliding the extrusion plate 311, and the knob 33 is rotated to rotate the threaded slider 310, so as to finely adjust the protective upper frame 2, so that the protective lower frame 1 and the protective upper frame 2 are fully adapted to the elevator opening, thereby improving the installation stability.

[0046] Example 3

[0047] Based on the above-mentioned embodiment 1 or embodiment 2, this embodiment proposes an elevator tunnel protection method, such as Figure 6-Figure 7As shown, a partition assembly 5 is provided inside the protective lower frame 1, and the partition assembly 5 includes a slide bar 51, a slider 52 and a folding frame 53. Slide bars 52 are fixedly installed at both ends of the slide bar 51, and the slider 52 slides inside the slide bar 51. A plurality of slide bars 51 are provided, and the plurality of slide bars 51 are equidistantly distributed in a straight line along the protective lower frame 1, and the sliders 52 at the ends of two adjacent slide bars 51 are connected to each other through the folding frame 53.

[0048] By directly pulling the slide bar 51 at the edge, multiple slide bars 51 can be unfolded. Since the sliders 52 at the ends of two adjacent slide bars 51 are connected to each other through the folding frame 53, the distance between the two adjacent slide bars 51 is fixed, and there is no need to adjust the position of the slide bar 51 one by one. In addition, there will be no problem that the distance between the two slide bars 51 is too large, resulting in the inability to intercept people.

[0049] A magnet 54 is fixedly mounted on the side of the slider 52 at the end of the slider 51 at the edge, and the surface of the support block 31 is wrapped with an iron coating, and the magnet 54 contacts the iron coating. The magnet 54 is adsorbed on the support block 31 to fix the position of the slider 51.

[0050] In this embodiment, a folding frame 53 is hinged between two adjacent sliders 52. When the slide bar 51 at the edge is pulled, multiple slide bars 51 slide, and the distance between two adjacent slide bars 51 is the same, avoiding the situation where the distance between the two slide bars 51 is too large, resulting in the inability to intercept people and posing a safety hazard.

[0051] The above specific embodiments are only several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
