[0002] Scaffolding is a working platform set up to ensure the smooth progress of each construction process, and the integrated attached lifting scaffolding is a scaffolding installed on the wall by attachment, and the scaffolding has its own climbing escalator. The existing scaffolding built on the outside of the building is very high. When workers work on the scaffolding, there is a risk of falling at any time, so anti-fall devices are needed to protect the lives of workers.

[0003] Based on the above, the inventors have found that the existing anti-fall device of an integrated attached lifting scaffold has the following main deficiencies. For example: the existing anti-fall device is fixed to the end face of the scaffold with a lock. When the worker climbs up or down, the lock needs to be unfastened from the end face of the scaffold, so that the lock needs to be moved when the worker's position changes, which is inconvenient for the worker to use. Moreover, the worker connects the safety rope to the lock. When the worker falls, the safety rope directly lifts the worker, which may cause physical injury to the worker. Summary of the Invention

Implementation Method

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] Example 1: Please refer to Figure 1-Figure 5 , the specific embodiments of the present invention are as follows:

[0025] Its structure includes a protective rod 1, a wall support support 2, a slide 3, an anti-fall baffle 4, and a main body 5. The rear end face of the protective rod 1 is provided with a wall support support 2, and there are two wall support supports 2, and the wall support support 2 is fixedly connected to the rear end face of the protective rod 1. The slide 3 is located at the front end face of the protective rod 1. There are more than ten anti-fall baffles 4, and the anti-fall baffles 4 are arranged on the end face of the slide 3. The main body 5 is engaged with the end face of the slide 3, and the main body 5 is movably engaged with the end face of the anti-fall baffle 4. The end face of the slide 3 is smooth.

[0026] The main body 5 includes a frame 51, a card frame 52, a positioning device 53, and a locking device 54. The end face of the frame 51 is provided with a card frame 52, and the card frame 52 is engaged with the end face of the protective rod 1. The positioning device 53 is installed on the inner end face of the frame 51, and the positioning device 53 is engaged with the end face of the anti-fall baffle 4. The locking device 54 is installed on the end face of the frame 51. The frame 51 is made of metal and has strong hardness, which is conducive to being stuck on the end face of the anti-fall baffle 4 through the positioning device 53, and then connected to the locking device 54 through a safety rope to protect the staff.

[0027] The positioning device 53 includes an inner groove 531, a positioning block 532, a limiting rod 533, a rewind spring 534, and a disengagement button 535. The inner groove 531 is set on the inner end surface of the frame 51, the positioning block 532 is installed in the middle position of the inner groove 531, and the positioning block 532 is engaged with the anti-fall baffle 4. The limiting rod 533 is set above the positioning block 532, the rewind spring 534 is installed on the bottom end surface of the inner groove 531, and the rewind spring 534 is movably matched with the end surface of the positioning block 532, the disengagement button 535 is installed on the top of the frame 51, and the disengagement button 535 is engaged with the positioning block 532. When the positioning block 532 is in the reset state, the angle formed with the end surface of the anti-fall baffle 4 is 30 degrees, which is beneficial for the positioning block 532 to be squeezed and deformed to move to the upper layer of the anti-fall baffle 4 when the staff climbs up.

[0028] The positioning block 532 includes a locking shaft a1, a positioning body a2, a locking tooth a3, a locking block a4, and a spring fixing groove a5. The locking shaft a1 is provided with two, and the locking shaft a1 is respectively engaged with the left and right ends of the inner groove 531. The end faces of the two sides of the positioning body a2 are connected to the locking shaft a1. The locking tooth a3 is provided with more than five, and the locking tooth a3 is arranged on the rear end face of the positioning body a2 and engages with the end face of the disengagement button 535. The locking block a4 is provided on the top end face of the positioning body a2, and the locking block a4 is engaged with the limit rod 533. The spring fixing groove a5 is located at the bottom end face of the positioning body a2, and the spring fixing groove a5 is connected to the rewinding spring 534. The end face of the positioning body a2 gradually expands from the end to the front end, which is conducive to driving the positioning body a2 to rotate and disengage from the anti-fall baffle 4 through the disengagement button 535, allowing the staff to easily drive the frame 51 to move downward when climbing under the tile digging.

[0029] The disengagement button 535 includes a mounting frame s1, a pressing block s2, a return spring s3, a lower top plate s4, and a tooth s5. The mounting frame s1 is arranged at the upper end of the inner groove 531, the pressing block s2 is engaged with the inside of the mounting frame s1, the return spring s3 is vertically mounted on the inner bottom end of the mounting frame s1, the lower top plate s4 is fixedly connected to the bottom end face of the pressing block s2, there are more than three teeth s5, and the teeth s5 are arranged on the end face of the lower top plate s4 and mesh with the latch teeth a3, the end face of the pressing block s2 is movably matched with the return spring s3, and the lower top plate s4 passes through the bottom end face of the mounting frame s1, which is convenient for the staff to drive the entire frame 51 to move downward.

[0030] When the worker wants to climb down, he can press the disengagement button 535 to engage with the positioning block 532, drive the positioning block 532 to disengage from the anti-fall baffle 4, thereby being able to move the frame 51 downward, and then release the disengagement button 535 and the rewinding spring 534 to restore the frame 51. The position can quickly drive the positioning block 532 to be stuck in the end face of the anti-fall baffle 4 again for positioning, and then the shape of the positioning body a2 can be smoothly stuck in the end face of the anti-fall baffle 4 to fix the entire frame 51 to prevent the staff from falling. The disengagement button 535 is then engaged with the latch tooth a3, and the disengagement button 535 can drive the positioning body a2 to rotate and disengage from the anti-fall baffle 4, allowing the staff to easily drive the frame 51 to move downward when climbing under the tiles. Finally, pressing the lower pressure block s2 drives the lower top plate s4 to move downward, so that the gear s5 can drive the gear to engage with the end face of the latch tooth a3, thereby driving the end face of the positioning body a2 to rotate, so that the positioning body a2 can be disengaged from the anti-fall baffle 4, allowing the staff to easily drive the entire frame 51 to move downward, and the frame 51 can also provide real-time protection for the safety of the staff.

[0031] Example 2: Please refer to Figure 6-Figure 7 , the specific embodiments of the present invention are as follows:

[0032] The locking device 54 includes a lifting block d1, a balancing block d2, a fixed plate d3, a binding groove d4, and a buffer device d5. The lifting block d1 is engaged with the inside of the frame 51, the balancing block d2 is arranged at the bottom end of the lifting block d1, the fixed plate d3 is welded to the end face of the lifting block d1, the binding groove d4 is located on the end face of the fixed plate d3, the buffer device d5 is installed at the bottom end of the interior of the frame 51, and the top end face of the buffer device d5 is connected to the bottom end face of the fixed plate d3. The end face of the lifting block d1 is U-shaped, and the end face of the binding groove d4 is circular, which is conducive to the buffer device d5 supporting the lifting block d1 to descend stably inside the frame 51, reducing the possibility of workers being injured by the safety rope.

[0033] The buffer device d5 includes a buffer tube d51, a lifting tube d52, a buffer spring d53, and a partition d54. The buffer tube d51 is fixedly connected to the internal bottom end of the frame 51, the lifting tube d52 is engaged with the internal top end of the buffer tube d51, and the top of the lifting tube d52 is connected to the fixed plate d3. There are two buffer springs d53, and one of them is set at the bottom end of the buffer tube d51, and the other is connected to the bottom of the lifting tube d52. The partition d54 is connected to the middle position of the two buffer springs d53. The buffer spring d53 and the lifting tube d52 are movably coordinated, which is conducive to slowing down the force of the staff being pulled by the safety rope when falling, thereby avoiding injury to the staff.

[0034] Based on the above embodiment, the specific working principle is as follows: the worker's safety rope is tied to the end face of the binding groove d4, so that when the worker drags the safety rope, the safety rope can also slide on the end face of the binding groove d4, and then the lifting block d1 is used to increase the engagement area with the inside of the frame 51, so that when the worker falls sideways, the buffer device d5 can support the lifting block d1 to descend stably inside the frame 51, reducing the possibility of the worker being injured by the safety rope. When the worker falls, the lifting tube d52 is driven downward by the fixed plate d3 to cushion the buffer. The spring d53 is squeezed and the downward pressure is transmitted to the end faces of the two buffer springs d53, so that the buffer spring d53 is squeezed and deformed laterally, thereby slowing down the force of the staff being pulled by the safety rope when falling, and avoiding injuries to the staff. When the staff falls, the lifting tube d52 is driven downward by the fixed plate d3 to squeeze the buffer spring d53, and the downward pressure is transmitted to the end faces of the two buffer springs d53, so that the buffer spring d53 is squeezed and deformed laterally, thereby slowing down the force of the staff being pulled by the safety rope when falling, and avoiding injuries to the staff.

[0035] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] The embodiments should therefore be considered in all respects as illustrative and non-restrictive, the scope of the invention being defined by the appended claims rather than the foregoing description, and all changes that come within the meaning and range of equivalents of the claims are intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
