Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a fall prevention mechanism based on building construction scaffolding. Background Technology

[0002] When carrying out construction work at a construction site, it is generally necessary to use construction scaffolds to assist in the construction process and improve the safety of construction workers.

[0003] A search revealed Chinese patent CN221073391U, which discloses a fall-prevention construction support frame, including a support platform. The upper left and right sides of the support platform are equipped with baffles. Multiple grooves are formed on the sides of the two baffles that are close to each other. Sliding blocks are slidably disposed within the grooves. A horizontal plate is disposed between two corresponding sliding blocks. Multiple protective mechanisms are disposed between the upper part of the horizontal plate and the bottom of the support platform. Vertical plates are provided on the upper left and right sides of the horizontal plate, and adjustment mechanisms are provided on the vertical plates. Guide rods are provided on the sides of the two horizontal plates that are close to each other, and multiple fall-prevention mechanisms are disposed on the guide rods. Each protective mechanism consists of multiple connecting blocks, and adjacent connecting blocks are hinged together.

[0004] Based on the above search results and existing technologies, the following findings were made:

[0005] Existing fall arrest construction scaffolding is not convenient to adjust its shape as needed during construction, and it is not conducive to meeting different protection requirements. It does not make full use of the equipment, thus reducing the efficiency of fall arrest construction scaffolding. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model proposes a fall protection mechanism based on a construction scaffold. The mechanism is securely mounted on the construction scaffold using a clamping device. When temporary shelter is needed, rotating a knob causes the worm gear to drive the worm wheel and winding shaft, releasing the traction rope and allowing the tilting frame to unfold outwards, enabling the fall protection net to be used as a shield. To adjust the height of the fall protection net, rotating a handwheel causes the lead screw to rotate, which in turn moves the positioning plate on the lead screw and slide bar, thus adjusting the net's height. Simultaneously, when lowering the fall protection net, the coil spring in the winding device drives the rotating shaft to wind up the protective net, thus meeting a wider range of protection needs.

[0007] The technical solution to achieve the purpose of this utility model is: a fall prevention mechanism based on a building construction support, including a connecting frame; the connecting frame includes a pair of left and right symmetrical uprights, and a flipping frame is provided on one side of each of the two uprights. The flipping frame includes a pair of left and right symmetrical slots, and the two uprights are respectively connected to the slots by hinges, and also includes;

[0008] A winder, which is located on a connecting frame;

[0009] A height adjustment assembly, which is located on a connecting frame;

[0010] A fall protection net, which is located on a connecting frame;

[0011] The height adjustment assembly includes a threaded hole in one of the slots, a lead screw threaded into each threaded hole, a positioning plate threaded onto the lead screw, a protective net fixedly connected to the bottom of the positioning plate, a protective box fixedly connected to one side of the slot, a rotating shaft rotatably connected to the inner walls of both sides of the protective box, coil springs fixedly connected to the left and right ends of the rotating shaft, and the end of the protective net away from the positioning plate passing through the protective box and wound around the rotating shaft.

[0012] In some embodiments, a handwheel is fixedly connected to the top of the lead screw.

[0013] In some embodiments, a slide rod is fixedly connected to both inner walls of another slot, and a positioning plate is slidably sleeved on the slide rod.

[0014] In some embodiments, a pair of symmetrical clamps are installed on one side of each of the two uprights.

[0015] In some embodiments, the bottom ends of the two uprights are fixedly connected to housings, each housing has a rotating hole, and each rotating hole is keyed to a worm gear. The inner walls on both sides of the two housings are rotatably connected to a winding shaft, and each winding shaft is keyed to a worm wheel. The worm gear and the worm wheel mesh with each other. Each side of the two slots is fixedly connected to a connector, and each connector is fixedly connected to a traction rope. The two traction ropes pass through the uprights and housings and are wound around the winding shafts.

[0016] In some embodiments, a knob is fixedly connected to the top of each of the two worm gears.

[0017] Compared with existing technologies, the significant advantages of this invention are:

[0018] This utility model utilizes the clamps of the connecting frame to securely install the mechanism on the construction support. When temporary shelter is needed, rotating the knob causes the worm gear to drive the worm wheel and the winding shaft to rotate, releasing the traction rope and allowing the tilting frame to flip outwards and unfold, so that the fall protection net can be used as a shelter net. When the position and height of the fall protection net need to be adjusted, rotating the handwheel causes the lead screw to rotate, thereby driving the positioning plate to move on the lead screw and the slide bar, realizing the adjustment of the fall protection net height. At the same time, when lowering the fall protection net, the coil spring in the winding device drives the rotating shaft to rotate and wind up the protective net, which can meet more different protection needs.

[0019] This invention addresses the problem that existing fall arrest construction scaffolds are inconvenient to adjust their shape as needed during construction, fail to meet different protection requirements, and do not fully utilize the equipment, thus reducing the efficiency of fall arrest construction scaffolds.

The flipping frame 3 includes a pair of symmetrical slots 301, and the two uprights 101 are respectively connected to the slots 301 by hinges. It also includes a winding device 2 located on the connecting frame 1; a height adjustment component 4 located on the connecting frame 1; and a fall protection net 5 located on the connecting frame 1. The height adjustment component 4 includes a screw threaded into one of the slots 301. Both the perforated and threaded holes are screwed with lead screws 401, and a positioning plate 501 is screwed onto the lead screws 401. A protective net 502 is fixedly connected to the bottom of the positioning plate 501. A protective box 201 is fixedly connected to one side of the slot box 301. A rotating shaft 202 is rotatably connected to the inner walls of both sides of the protective box 201. A coil spring 203 is fixedly connected to the left and right ends of the rotating shaft 202. The end of the protective net 502 away from the positioning plate 501 passes through the protective box 201 and is wound and connected to the rotating shaft 202. The lead screw 401 facilitates the raising and lowering of the protective net 502 on the positioning plate 501.

[0036] like Figure 8 As shown, in one embodiment, a handwheel 402 is fixedly connected to the top end of the lead screw 401; the handwheel 402 facilitates the rotation of the lead screw 401.

[0037] like Figure 9 As shown, in one embodiment, the inner walls of both sides of another slot box 301 are fixedly connected to a slide rod 403, and the positioning plate 501 is slidably sleeved on the slide rod 403; the slide rod 403 facilitates the improvement of stability when the positioning plate 501 is moved.

[0038] like Figure 5 As shown, in one embodiment, a pair of symmetrical clamps 102 are installed on one side of each of the two uprights 101; by setting the uprights 101 and clamps 102, the entire fall arrest mechanism can be quickly and firmly installed on the building construction support, which improves the convenience and stability of installation.

[0039] like Figure 5 and Figure 8 As shown, in one embodiment, the bottom ends of the two uprights 101 are fixedly connected to housings 103. Rotation holes are provided on both housings 103, and worm gears 107 are keyed into each of the two rotation holes. Rewinding shafts 104 are rotatably connected to the inner walls on both sides of the two housings 103, and worm wheels 105 are keyed onto each of the two winding shafts 104.
