DETAILED DESCRIPTION

[0026] See also Figures 1 to 6As shown, the embodiment of the present application provides an anti-falling device for a scaffold, including an anti-falling component 4, which is installed on a wall-mounted support 2 of the scaffold, one end of the wall-mounted support 2 is arranged on the wall, and the other end of the wall-mounted support 2 is connected to the guide rail 1 of the scaffold, the anti-falling component 4 includes an anti-falling pendulum block 41, one side of the anti-falling pendulum block 41 is provided with a slot, a long axis 46 is arranged in the slot, and a movable trigger block torsion spring 45 is sleeved on the long axis 46, the trigger block torsion spring 45 is used for when the trigger block 44 and the anti-falling crosspiece of the guide rail 1 do not collide, the trigger block 44 and the guide rail 1 are perpendicular to each other, a movably connected load-bearing shaft 42 is arranged through the center of the anti-falling pendulum block 41, the load-bearing shaft 42 is arranged on the wall-mounted support 2, a movable trigger block 44 is sleeved on the load-bearing shaft 42, the trigger block 44 is located in the slot, the trigger block 44 is detachably connected to the anti-falling crosspiece of the guide rail 1, and the two extending ends of the trigger block torsion spring 45 are respectively abutted The trigger block 44 and the slotted inner wall, both sides of the anti-falling pendulum block 41 are provided with pendulum block tension springs 43, and the pendulum block tension springs 43 are used to reset the anti-falling pendulum block 41. The end of the pendulum block tension spring 43 away from the anti-falling pendulum block 41 is connected to the wall support 2. A top support device 3 can also be arranged above the anti-falling component 4, and the top support device 3 includes a top support seat, which is movably arranged on the wall support 2 through a pin shaft, and a screw-connected adjusting screw rod is arranged on the top support seat. Both ends of the adjusting screw rod are provided with threads, and the screw directions of the threads are opposite. A screw-connected top support head is arranged at the end of the adjusting screw rod away from the top support seat. When the wall support 2 is fixed, the length between the top support seat and the top support head is increased by rotating the adjusting screw rod. When the top support head can be clamped between the anti-falling cross bars of the guide rail 1, the adjusting screw rod is continued to be rotated so that the top support head and the anti-falling cross bars of the guide rail 1 are firmly clamped, so that the top support device 3 further supports the guide rail 1 and improves the stability of the support.

[0027] In the above scheme, by setting the anti-fall component 4, when the scaffolding is stationary, the trigger block 44 is engaged with the anti-fall cross piece of the guide rail 1, and the guide rail 1 is tightened to support the scaffolding. When the scaffolding suddenly falls, the guide rail 1 slides down with the scaffolding as a whole. At this time, the anti-fall cross piece of the guide rail 1 will touch the trigger block 44, causing the trigger block 44 to rotate clockwise. The clockwise rotation of the trigger block 44 drives the anti-fall pendulum block 41 to rotate clockwise, thereby causing the anti-fall pendulum block 41 to be engaged with the anti-fall cross piece of the guide rail 1, which can effectively freeze the scaffolding, has a fast reaction speed, and has an anti-falling effect on the scaffolding, thereby improving the safety of the scaffolding in the construction process, providing a solid safety guarantee for the construction site, reducing the occurrence of accidents, and protecting the lives of workers.

[0028] In some possible implementations, see Figures 3 to 6As shown, the anti-falling pendulum block 41 has a first clamping end 411 and a second clamping end 412, the first clamping end 411 is detachably connected to the anti-falling cross piece of the guide rail 1, the second clamping end 412 is detachably connected to the wall-mounted support 2, a protrusion 413 is provided on the side of the first clamping end 411 close to the wall-mounted support 2, the protrusion 413 is detachably connected to the anti-falling cross piece of the guide rail 1, the trigger block 44 has a short baffle 442 and an extended tongue 441, the extended tongue 441 is detachably connected to the anti-falling cross piece of the guide rail 1, and the short baffle 442 is detachably connected to the second clamping end 412.

[0029] It should be noted that when the first clamping end 411 is clamped between the anti-falling crosspieces of the guide rail 1, the protrusion 413 abuts against the anti-falling crosspiece of the guide rail 1, so that the clamping effect between the first clamping end 411 and the anti-falling crosspiece of the guide rail 1 is better. During the rising process of the scaffolding, the trigger block 44 is always in contact with the anti-falling crosspiece of the guide rail 1, and the anti-falling pendulum block 41 and the trigger block 44 are not subjected to force. When the scaffolding suddenly falls, the anti-falling crosspiece of the guide rail 1 touches the extended tongue 441 of the trigger block 44, causing the trigger block 44 to rotate clockwise. The clockwise rotation of the trigger block 44 drives the anti-falling pendulum block 41 to rotate clockwise through the short baffle 442, so that the anti-falling The first clamping end 411 of the pendulum block 41 is clamped between the anti-falling crosspieces of the guide rail 1. At the same time, the second clamping end 412 of the anti-falling pendulum block 41 is clamped at the bottom of the wall support 2, thereby supporting the scaffolding and preventing it from falling. When the scaffolding is stuck by the first clamping end 411 after suddenly falling, if it needs to be reset, it is necessary to start the scaffolding to make it rise. When the scaffolding rises, the first clamping end 411 is pushed upward by the anti-falling crosspiece of the guide rail 1, and at the same time, it rotates counterclockwise under the tension of the pendulum block tension spring 43, and at the same time drives the trigger block 44 to rotate counterclockwise until the anti-falling pendulum block 41 is in a parallel state with the guide rail 1.

[0030] When the scaffold is stationary, the anti-falling pendulum block 41 is parallel to the guide rail 1, and the trigger block 44 is always perpendicular to and crosses the anti-falling crossbar of the guide rail 1. When the scaffold is descending, the trigger block 44 plays a major role. When descending, the anti-falling crossbar of the guide rail 1 will touch the trigger block 44, so that the anti-falling pendulum block 41 will rotate. When the scaffold is descending at a uniform speed, the anti-falling crossbar of the guide rail 1 touches the extension tongue 441, so that the anti-falling pendulum block 41 will rotate through the short baffle 442. The falling pendulum block 41 rotates clockwise at a certain small angle, so that the first clamping end 411 of the anti-falling pendulum block 41 will not be stuck between the anti-falling crosspieces of the guide rail 1, and it will always swing slightly along the load-bearing axis 42. Once the scaffolding suddenly falls, the trigger block 44 is subject to an increased force from the anti-falling crosspiece of the guide rail 1, so that the short baffle 442 will suddenly push the anti-falling pendulum block 41 to rotate clockwise, thereby causing the first clamping end 411 of the anti-falling pendulum block 41 to quickly get stuck between the anti-falling crosspieces of the guide rail 1, thereby playing an anti-falling role.

[0031] By setting the anti-fall component 4, when the scaffold is stationary, the trigger block 44 is engaged with the anti-fall cross piece of the guide rail 1, and the guide rail 1 is tightened to support the scaffold. When the scaffold suddenly falls, the guide rail 1 slides down with the scaffold as a whole. At this time, the anti-fall cross piece of the guide rail 1 will touch the trigger block 44, causing the trigger block 44 to rotate clockwise. The clockwise rotation of the trigger block 44 drives the anti-fall pendulum block 41 to rotate clockwise, thereby causing the anti-fall pendulum block 41 to be engaged with the anti-fall cross piece of the guide rail 1, which can effectively block the scaffold, has a fast reaction speed, and has a fall-proof effect on the scaffold, thereby improving the safety of the scaffold in the construction process, providing a solid safety guarantee for the construction site, reducing the occurrence of accidents, and protecting the lives of workers.

[0032] This specific embodiment is merely an explanation of the utility model, and it is not a limitation of the utility model. After reading this specification, those skilled in the art can make non-creative modifications to the embodiment as needed, but as long as it is within the protection scope of the utility model, it is protected by the patent law.
