[0034] Example 1

[0035] A temporary stair protection mechanism for use during construction comprises a lifting unit 1, a temporary stair protection unit 2 and a fixing unit 4.

[0039] The lifting unit 1 can drive the first support 21 and the second support 22 to move upward along the fixing unit 4 in the stair gap.

[0040] In this embodiment, the first pillar 21 and the second pillar 22 have the same structure; the protective device includes a plurality of support rods 23, wherein both ends of the support rods 23 are hinged to the first pillar 21 and the second pillar 22 respectively.

[0041] In this embodiment, the support rod 23 can be a connecting rod with a fixed distance, or a telescopic rod with adjustable length to adapt to different stair widths, and is preferably a telescopic rod.

[0042] When multiple temporary stair protection assemblies are stacked and connected, the first pillar 21 and the second pillar 22 in one temporary stair protection assembly are fixedly connected to the first pillar 21 and the second pillar 22 in another adjacent temporary stair protection assembly through a joint snap-fit ​​device 3; the ends of the first pillar 21 and the second pillar 22 are both provided with shoulders; the joint snap-fit ​​device 3 includes a sleeve 31, which is sleeved on the outside of the shoulders of the two adjacent first pillars 21 or second pillars 22.

[0043] Among them, the joint clip device 3 also includes a limit inner buckle 32, which includes two limit baffles 323, which are fixedly connected to the inner wall of the sleeve 31, and a limit opening is provided on the limit baffle 323. Two inner buckle rods 322 are slidably connected in the limit opening. The inner buckle rods 322 pass through the two limit openings and extend to both ends of the openings. The surface of the extended end adjacent to the inner wall of the sleeve 31 is fixedly connected with an inner buckle protrusion 321. A two-way screw 324 is provided between the two limit baffles 323, and the two-way screw 324 is threadedly connected to the inner buckle rod 322. The bidirectional screw 324 is rotatably connected to the sleeve 31; the bidirectional screw 324 has a smooth surface near both ends, and a first limiting ring 325 and a first limiting ring 326 are respectively provided at both ends. The first limiting ring 326 is fixedly connected to the inner wall of the sleeve 31, and the bidirectional screw 324 is rotatably set in the first limiting ring 326. The first limiting ring 325 passes through the sleeve 31 and is fixedly connected to the sleeve 31; when the temporary stair protection components are stacked and connected, the inner buckle protrusion 321 fits against the inner wall of the first pillar 21 / second pillar 22.

[0044] In this embodiment, the jacking unit 1 includes two jacking components, the jacking components include a frame 12 and a jacking device 11 arranged on the frame 12, and the frame 12 is installed on the ground of the stair shaft; the driving end of the jacking device 11 is provided with a driving block adapted to the shoulder of the first pillar 21 or the second pillar 22.

[0045] A clamping device is provided on the side panel of the frame 12, and the clamping device includes a clamping block 14. The clamping block 14 includes a first clamping block and a second clamping block. The first clamping block and the second clamping block are correspondingly clamped on the outside of the first pillar 21 / the second pillar 22. The first clamping block and the second clamping block have grooves adapted to the first pillar 21 / the second pillar 22, which are used to provide resistance to prevent the first pillar 21 / the second pillar 22 from sliding down; the first clamping block and the second clamping block are both driven by the hydraulic cylinder 13, and the driving end of the hydraulic cylinder 13 is set at an angle to the first pillar 21 / the second pillar 22.

[0046] In this embodiment, the fixing unit 4 includes a telescopic clip and a fixed fastener. The telescopic clip is respectively arranged at both ends of the first pillar 21 / the second pillar 22 near the shaft shoulder, and the fixed fastener is installed on the stair transition platform; the telescopic clip cooperates with the fixed fastener so that the first pillar 21 / the second pillar 22 can only move upward in one direction relative to the fixed fastener.

[0047] The telescopic clamp includes a limiting tube 44, which is vertically arranged in the first pillar 21 / second pillar 22. One end of the limiting tube 44 is fixedly connected to the inner wall of the first pillar 21 / second pillar 22, and the other end passes through the first pillar 21 / second pillar 22 and is flush with the outer surface of the first pillar 21 / second pillar 22. A wedge-shaped block 43 and a spring 45 are arranged in the limiting tube 44. The flat end of the wedge-shaped block 43 is fixedly connected to the inner wall of the first pillar 21 / second pillar 22 through the spring 45. The tip of the wedge-shaped block 43 extends along the limiting tube 44 until the slope of the tip of the wedge-shaped block 43 is exposed outside the first pillar 21 / second pillar 22.

[0048] Among them, the fixing fastener includes a C-shaped tube sleeve 41 and two lugs 42 respectively arranged at both ends of the C-shaped tube sleeve 41 and facing away from the notch of the C-shaped tube sleeve 41. The C-shaped tube sleeve 41 is used to be sleeved on the outside of the first pillar 21 / second pillar 22. The lug 42 is fixedly connected to the stair transition platform, and a wedge-shaped block 43 is clamped on the upper end of the lug 42 to prevent the first pillar 21 / second pillar 22 from sliding down.

[0049] Among them, first, the jacking unit 1 gradually lifts the temporary stair protection unit 2 as a whole from bottom to top. During the jacking, the upper surface of the tip of the wedge-shaped block 43 of the telescopic clamp on the first pillar 21 and the second pillar 22 is a slope that gradually widens from top to bottom. Therefore, when the telescopic clamp passes through the fixed fastener, the slope of the wedge-shaped block 43 is squeezed to cause the block to retract into the limiting tube 44. The temporary stair protection unit 2 continues to rise. After the telescopic clamp passes through the fixed fastener, the wedge-shaped block 43 rebounds outward, and the lower surface of the tip of the wedge block 43 is a plane. The fixed fastener will provide a blocking effect on the telescopic clamp to prevent the temporary stair protection unit 2 from sliding down. Since the fixed fastener is fixed on the stair transition platform, the fixed fasteners on each layer will provide support for the temporary stair protection unit 2, thereby enhancing stability and safety.
