[0002] During the construction process, in order to protect workers from dangers such as falling from heights, it is necessary to install anti-fall nets on the outside of the building. The currently widely used construction safety protection devices mainly include support rods and protective nets. The support rods support the protective nets, which can effectively prevent workers from falling further if they fall onto the protective nets. However, due to the thin structure of the protective nets, there is a certain risk of them breaking. At the same time, if workers fall onto the support rods, they will still suffer certain injuries. The structure of the support rods is as follows: Figure 1 shown.

DETAILED DESCRIPTION

[0026] like Figure 2-4 As shown, a construction safety anti-falling device includes a fixed plate 1 connected to the outer wall of the building, a first anti-falling portion is rotatably connected to the outer side of the fixed plate 1, and a second anti-falling portion is rotatably connected to the upper side of the first anti-falling portion. A connecting frame 2 is provided on the upper front side of the fixed plate 1, and a plurality of parallel anti-falling ropes 3 are connected between the second anti-falling portion and the connecting frame 2;

[0027] The first anti-fall part includes an L-shaped first anti-fall frame 4, the horizontal part of which is connected to a first anti-fall net 5; the second anti-fall part includes an L-shaped second anti-fall frame 6, and the second anti-fall net 7 is connected to the second anti-fall frame 6.

[0028] The fixing plate 1 can be straight or other shapes that fit the building's exterior wall. The width of the first anti-fall section is the same as that of a traditional anti-fall net. The angle between the bottom surface of the second anti-fall section and the vertical section of the first anti-fall section is greater than 90 degrees, and the second anti-fall section can only rotate upward, not downward.

[0029] like Figure 7 As shown, the interior of the connecting frame 2 is provided with several connecting cavities 8 with top openings, the inner top of the connecting cavity 8 is provided with a contact switch 9, the interior of the connecting cavity 8 is slidably connected to a limit block 10, the end of the anti-fall rope 3 passes through the top opening of the connecting cavity 8 and is fixedly connected to the limit block 10, the top of the limit block 10 is provided with a connecting contact block 11, the outer sleeve of the anti-fall rope 3 on the upper side of the limit block 10 is provided with a support spring 12, and the connecting contact block 11 is arranged opposite to the contact switch 9.

[0030] When the anti-fall rope 3 is compressed, the anti-fall rope 3 drives the limit block 10 to move upward along the connecting cavity 8. When the connecting contact block 11 contacts the contact switch 9, a connection loop is formed.

[0031] like Figure 4 and Figure 6 As shown, the horizontal section of the first anti-fall frame 4 is rotatably connected to the lower outer side of the fixed plate 1, and two arc-shaped guide frames 13 are fixed to the front side of the fixed plate 1. The guide frames 13 are provided with arc-shaped guide grooves inside, and the frame body of the horizontal section of the first anti-fall frame 4 is arranged through the guide grooves;

[0032] An electromagnet 14 is provided on the top of the guide frame 13, and a permanent magnet 15 is connected to the frame body of the horizontal section of the first anti-fall frame 4. The permanent magnet 15 and the electromagnet 14 are arranged opposite to each other up and down. A buffer spring 16 is connected between the permanent magnet 15 and the front side of the fixed plate 1, and the buffer spring 16 is arranged along the arc-shaped guide groove.

[0033] When the connecting contact block 11 contacts the contact switch 9, the circuit connected to the electromagnet 14 is connected, and the electromagnet 14 gives the permanent magnet 15 a downward repulsive force, causing the first anti-fall frame 4 to move downward along the guide groove, and the buffer spring 16 buffers the movement of the first anti-fall frame 4.

[0034] Alternatively, when the contact switch 9 contacts the connecting contact block 11 , the internal circuit of the electromagnet 14 may be reversed, causing the magnetic pole of the electromagnet 14 to change from attracting the permanent magnet 15 to repelling the permanent magnet 15 .

[0035] like Figure 6 As shown, several L-shaped reinforcement brackets 17 are provided on the lower side of the first anti-fall frame 4. The bending part of the reinforcement bracket 17 is set in an arc shape. One end of the reinforcement bracket 17 is connected to the lower side of the horizontal section of the first anti-fall frame 4, and the other end of the reinforcement bracket 17 is connected to the outer side of the vertical section of the first anti-fall frame 4.

[0036] The length of the reinforcement bracket 17 is greater than the width of the first anti-fall bracket. The provision of the reinforcement bracket 17 can prevent a rigid fracture between the horizontal section and the vertical section of the first anti-fall bracket 4 .

[0037] like Figure 4 As shown, the second anti-fall frame 6 includes an anti-fall section and a protective section connected to the outer end of the anti-fall section. One side of the anti-fall section is rotatably connected to the top of the vertical section of the first anti-fall frame 4. The other side of the anti-fall section is tilted upward. The width of the anti-fall section is not less than the width of the horizontal section of the first anti-fall frame 4.

[0038] The second anti-falling net 7 is connected to the inside of the anti-falling section, and the anti-falling rope 3 is connected to one end of the anti-falling section away from the first anti-falling frame 4.

[0039] When the anti-fall rope 3 is impacted, the second anti-fall frame 6 rotates toward the upper side of the first anti-fall frame 4, so that a protective space is formed between the second anti-fall frame 6 and the first anti-fall frame 4. The second anti-fall frame 6 can block falling objects from above and prevent the falling worker from suffering secondary injuries from falling objects.

[0040] like Figure 7 As shown, the inner side elevation of the connection cavity 8 is provided with a plurality of welding points 18 , which are located on the upper side of the limiting block 10 , and the distance between the welding points 18 and the contact switch 9 is greater than the height of the connection contact block 11 .

[0041] The welding point 18 can limit the limit block 10 to prevent the limit block 10 from moving upward, thereby preventing the contact block 11 from accidentally touching the contact switch 9 .

[0042] The fixing plate 1 is provided with a plurality of fixing holes 19 for accommodating fixing screws.

[0043] Directions:

[0044] When the device is used, the anti-fall device is fixed to the outside of the building through the fixing plate 1, and the first anti-fall part and the second anti-fall part are used to protect the construction workers.

[0045] When a worker falls, he falls onto the anti-fall rope 3, which provides preliminary cushioning for the worker's fall.

[0046] When the anti-fall rope 3 is impacted, the large linkage limit block 10 of the anti-fall rope 3 moves upward along the connecting cavity 8, the connecting contact block 11 contacts the contact switch 9, the circuit of the electromagnet 14 is connected, and the electromagnet 14 exerts a downward repulsive force on the permanent magnet 15, causing the first anti-fall bracket to rotate downward, so that the first anti-fall bracket has an initial velocity, further cushioning the worker's fall and reducing injuries to the worker;

[0047] When the worker continues to press down on the anti-fall rope 3, the anti-fall rope 3 pulls the second anti-fall frame 6 to rotate upward, so that the second anti-fall frame 6 covers the upper side of the first anti-fall frame 4 to prevent high-rise falling objects from causing secondary injuries to the workers.

[0048] The above-mentioned specific embodiments are only specific cases of the present invention. The patent protection scope of the present invention includes but is not limited to the product form and style of the above-mentioned specific embodiments. Any construction safety anti-falling device that complies with the claims of the present invention and any appropriate changes or modifications made thereto by ordinary technicians in the corresponding technical field shall fall within the patent protection scope of the present invention.
