Description

Technical Field

[0001] This utility model relates to the field of construction safety technology, and in particular to a fall prevention device for construction. Background Technology

[0002] In existing construction equipment, A-frame ladders are frequently used as tools for working at heights. However, traditional A-frame ladders have several problems in their design and use. First, the support structure of traditional A-frame ladders is relatively simple, lacking effective anti-tipping and anti-fall devices. When construction workers are working on the A-frame ladder, it is easy for it to collapse under lateral forces or unbalanced loads, causing workers to fall. Second, traditional A-frame ladders have poor stability, especially in complex and changing construction site environments, making it difficult to guarantee the safety of construction workers.

[0003] Therefore, a construction fall protection device is proposed, which effectively improves the stability of construction workers and prevents the danger of workers falling due to device collapse by forming a biaxially stable triangular structure. Utility Model Content

[0004] In order to overcome the problem that traditional construction equipment is prone to collapse when subjected to lateral forces or unbalanced loads during daily use, which could lead to workers falling and causing serious safety accidents.

[0006] Preferably, the angle of the threaded rod is adjusted by rotating the first connecting plate around the first pivot. The threaded rod is then rotated by turning the handle, and its position is adjusted by moving it up and down through the threaded connection between the threaded rod and the fixed block. The device is supported by the support block contacting the ground, thus providing support to the vertical side of the A-frame ladder structure and forming a stable triangular structure. Combined with the triangular support structure of the A-frame ladder itself, this forms two axial triangular support structures, improving the stability of the construction workers and preventing the device from collapsing from its vertical side and causing workers to fall.

[0008] Preferably, the support assembly includes a second connecting block and a second rotating shaft; the second connecting block is disposed below the top plate, and the second rotating shaft is disposed inside the second connecting block.

[0009] Preferably, the support assembly also includes a second connecting plate and a fixing rod; the second connecting plate is provided on the outer side of the second rotating shaft, the second connecting plate and the second rotating shaft are rotatably connected, and a fixing rod is provided on one side of the second connecting plate. Multiple sets of fixing rods are provided. In use, the second connecting plate is rotated to make the second connecting plate rotate around the second rotating shaft, and the fixing rods allow construction personnel to climb and handle the situation.

In use, the rotation angle of the second connecting plate is limited by the rotatable connection between the third connecting frame and the fourth connecting frame.

[0012] Preferably, the anti-slip component includes a first anti-slip pad and a second anti-slip pad; the first anti-slip pad is provided on the outside of the fixing rod, and the second anti-slip pad is provided on the top plate. In use, the first anti-slip pad increases the friction between the fixing rod and the construction personnel when climbing, and the second anti-slip pad increases the friction on the surface of the top plate to prevent personnel from slipping.

[0013] The beneficial effects of this utility model are:

[0022] Please see Figure 2-4 In this embodiment, the first connecting assembly includes a first connecting rod 201, a first connecting frame 202, and a second connecting frame 203. A first connecting rod 201 is provided on one side of the first connecting plate 102, and a first connecting frame 202 is provided on the outer side of the first connecting rod 201. The first connecting frame 202 and the first connecting rod 201 are rotatably connected. A second connecting frame 203 is provided on one side of the first connecting frame 202, and the second connecting frame 203 and the first connecting frame 202 are rotatably connected. In use, the rotation angle of the first connecting plate 102 is limited by the rotatable connection between the second connecting frame 203 and the first connecting frame 202. The support assembly includes... A second connecting block 301 and a second rotating shaft 302 are provided below the top plate 1. A second connecting block 301 is provided on the inner side of the second connecting block 301. The support assembly also includes a second connecting plate 303 and a fixing rod 304. A second connecting plate 303 is provided on the outer side of the second rotating shaft 302. The second connecting plate 303 and the second rotating shaft 302 are rotatably connected. A fixing rod 304 is provided on one side of the second connecting plate 303. Multiple sets of fixing rods 304 are provided. In use, the second connecting plate 303 is rotated around the second rotating shaft 302 by rotating the second connecting plate 303. The fixing rods 304 allow construction personnel to climb.

[0023] The second connecting assembly includes a second connecting rod 401 and a third connecting frame 402; the second connecting rod 401 is provided on one side of the second connecting plate 303, and the third connecting frame 402 is provided on the outer side of the second connecting rod 401.

Combined with the triangular support structure of the ladder structure itself, a triangular support structure is formed in two axes, which can improve the stability of construction workers during construction and prevent the device from collapsing from its vertical side, thus preventing the danger of construction workers falling.
