[0002] The anti-fall device is a safety device used to protect construction workers from falling from heights when performing aerial work. The anti-fall device can effectively prevent construction workers from falling from heights, thereby greatly improving the safety of construction work. During aerial work, falling accidents often lead to serious injuries or even death, so the anti-fall device is crucial in protecting the lives of workers. After installing the anti-fall device, construction workers can perform aerial work more confidently without having to worry about the danger of falling all the time, thereby improving work efficiency.

[0003] In the prior art, for example, in the patent with announcement number CN211081099U, a safety fall prevention device for construction is disclosed. When construction workers or other heavy objects fall on the protective net, the connecting rod presses the spring downward to play a buffering role, thereby reducing personal injury. However, in actual use, when construction workers or heavy objects fall and land on the protective net, although the compression of the spring can provide a certain buffering effect, after the protective net reaches its maximum stretching limit, due to the effect of inertia, an upward rebound force is generated, which will cause the fallen person or heavy object to be thrown up again, thereby increasing the risk of a secondary fall. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a construction safety fall prevention device, which solves the problem that in actual use, when construction workers or heavy objects fall and land on a protective net, although the compression of the spring can provide a certain buffering effect, after the protective net reaches its maximum stretching limit, due to the effect of inertia, an upward rebound force is generated, which can cause the fallen person or heavy object to be thrown up again, thereby increasing the risk of a secondary fall.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-4 , a construction safety anti-falling device, comprising two brackets 1, the inner sides of the two brackets 1 are fixedly connected with a fixing component 2, and a protective net 3 is fixedly connected between the two fixing components 2;

[0026] The fixing assembly 2 includes two fixing plates 201 and an arc-shaped plate 204. The fixing plates 201 are fixedly connected to the bracket 1. The bottoms of the two fixing plates 201 are rotatably connected to a rotating block 202. The outer sides of the rotating blocks 202 are fixedly connected to a mounting rod 203. One side of the protective net 3 is fixedly connected to the two mounting rods 203.

[0027] The arc plate 204 is fixedly connected to the bracket 1, and the mounting rod 203 is slidably connected to the arc plate 204. A limiter is provided on the arc plate 204, and the limiter is used to limit the position of the mounting rod 203. If a construction worker or a heavy object accidentally falls and contacts the protective net 3, the mesh surface of the protective net 3 will be subjected to impact force, which will be transmitted to the mounting rod 203 connected thereto, so that the mounting rod 203 rotates with the rotating block 202 as the rotation point. After the limiter is subjected to the impact, it will automatically break, releasing the constraint on the mounting rod 203, and the mounting rod 203 will slide along the trajectory of the arc plate 204, driving the two ends of the protective net 3 to close toward the center. As the protective net 3 closes, the fallen construction worker or heavy object will be firmly held in the protective net 3, thereby avoiding the sudden rebound caused by the protective net 3 reaching the maximum stretching limit, thereby greatly reducing the risk of secondary falling.

[0028] A guide groove 207 is provided on the inner side of the arc plate 204, and a guide block 206 is fixedly connected to the mounting rod 203, and the guide block 206 is slidably connected inside the guide groove 207. The guide groove 207 provides a sliding path for the guide block 206 on the mounting rod 203, ensuring that the mounting rod 203 can slide smoothly along a predetermined trajectory when impacted, so that the two ends of the protection net 3 are closed toward the center, and the falling construction personnel or heavy objects are caught in the protection net 3.

[0029] The top of the arc plate 204 is provided with a socket, and the limiting member is inserted into the socket. The design of the socket facilitates the limiting member to be inserted therein, so as to fix and limit the mounting rod 203, thereby keeping the protective net 3 in a horizontally unfolded state.

[0030] The limiting member is a limiting rod 205, which is movably inserted in the inside of the socket, and the bottom of the limiting rod 205 overlaps the inner bottom wall of the guide groove 207. When subjected to sufficient impact force, such as the fall of construction workers or heavy objects, the force of the protective net 3 will be transmitted to the installation rod 203, thereby causing the limiting rod 205 to be stressed. Since the limiting rod 205 is movably inserted in the socket, the limiting rod 205 will break when a certain force is reached, thereby releasing the constraint of the installation rod 203 and allowing it to slide along the guide groove 207.

[0031] The bracket 1 includes a first crossbar 101 and a second crossbar 102, which are symmetrically arranged in the vertical direction, and are fixedly connected to the building. A vertical bar 103 is equidistantly fixedly connected between the first crossbar 101 and the second crossbar 102, and the vertical bar 103 is vertically arranged. The first crossbar 101 and the second crossbar 102 are symmetrically arranged in the vertical direction, and are fixedly connected to the building, providing a stable foundation for the entire bracket 1.

[0032] A reinforcement rod 104 is fixedly connected equidistantly between the first crossbar 101 and the second crossbar 102, and the reinforcement rod 104 is obliquely arranged between the two vertical rods 103. Two fixing plates 201 are symmetrically fixedly connected to the second crossbar 102, and the back of the arc plate 204 is fixedly connected to the second crossbar 102, the vertical rod 103 and the reinforcement rod 104. The reinforcement rod 104 is obliquely arranged between the two vertical rods 103, forming a triangular stable structure, which enhances the overall rigidity of the bracket 1 and can effectively prevent the bracket 1 from accidentally breaking when the protective net 3 is impacted.

[0033] Working principle: In the initial state, the limiter limits the position of the installation rod 203, so that the protection net 3 remains horizontally unfolded, providing comprehensive safety protection for the construction site;

[0034] Once a construction worker or a heavy object accidentally falls and touches the protective net 3, the surface of the protective net 3 will be subjected to an impact force, which will be transmitted to the mounting rod 203 connected thereto, causing the mounting rod 203 to rotate with the rotating block 202 as the rotation point;

[0035] At this time, the limit piece used to fix the position of the installation rod 203 will automatically break after being impacted, releasing the constraint on the installation rod 203, and the guide block 206 on the installation rod 203 will slide along the guide groove 207 of the arc plate 204, driving the two ends of the protection net 3 to close toward the center. As the protection net 3 closes, the fallen construction workers or heavy objects will be firmly caught in the protection net 3, thereby avoiding the sudden rebound caused by the protection net 3 reaching the maximum stretching limit, thereby greatly reducing the risk of secondary falling.
