[0016] The beneficial effects of the present invention are:

[0017] 1. The safety protection component is used to carry the roof construction workers and can drive the construction workers to move safely to any position on the roof to prevent the construction workers from slipping when walking on the inclined roof. During the construction workers' roof repair process, the waste materials removed from the roof can be safely transported to the designated position at the bottom of the factory.

[0019] 3.

The removed pull-out plate can also be used to place the construction workers' repair tools and materials, which can move synchronously with the bearing plate to facilitate the repair of different roof positions, thereby improving the construction workers' operating efficiency in repairing any position of the roof.

[0020] 4.

The traction ropes in the first guide wheel and the second guide wheel can also be taken out, and the two sets of traction ropes are respectively connected to the first hanging rope ring and the second hanging rope ring, so that the ends of the two sets of traction ropes extend to the vicinity of the first climbing ladder and the second climbing ladder, so that the other two construction workers can perform horizontal construction operations on the top roof of the factory building at different positions while pulling the traction rope on one side, thereby reducing the self-traction of the construction workers and improving the efficiency of the construction workers moving on the roof.

[0021] 5. The guide rail is fixedly connected to the first hanging rope ring, which is used for the synchronous linkage between the guide rail and the bearing plate. The waste remaining in the roof repair process is put into the guide cavity by using one side of the isolation plate on the guide cavity, and slides into the first lower hopper, so that the waste remaining on the roof can fall safely to the designated position, avoiding the safety hazard caused by the waste falling from a high altitude.

The top of the factory building 1 is symmetrically provided with two groups of inclined roofs with the central axis as the center, and the connection between the roof and the safety protection component 2 is rolling fit.

[0032] Specifically, the safety protection component 2 is used to carry the roof construction workers and can drive the construction workers to move safely to any position on the roof to prevent the construction workers from slipping when walking on the inclined roof. During the process of roof repair by the construction workers, the waste materials removed from the roof can be safely transported to the designated position at the bottom of the factory building. After the safety protection component 2 is flipped over, it is convenient to switch it to the other side of the roof for use.

[0035] Specifically, the inner tube 22 is slidably connected to the outer tube 21, and the inner tube 22 is used to adjust the telescopic distance during the sliding process to meet the needs of factories with different lengths, and the first climbing ladder 23 is mounted on one end of the outer tube 21, and the second climbing ladder 24 is mounted on one end of the inner tube 22. The first climbing ladder 23 is used for construction workers to climb into the personnel carrying mechanism 28, and the second climbing ladder 24 is used to facilitate the personnel on the personnel carrying mechanism 28 to leave the roof of the factory building 1 after the construction is completed;

[0036] The personnel carrying mechanism 28 is connected to a traction rope on one side, which passes through two groups of first guide wheels 25 and two groups of second guide wheels 27 in sequence. The construction personnel on the personnel carrying mechanism 28 can gradually approach the second climbing ladder 24 while pulling the other end of the traction rope. The construction personnel on the personnel carrying mechanism 28 can perform horizontal construction operations at different positions on the top roof of the factory building 1 during the process of moving from the first climbing ladder 23 to the second climbing ladder 24.

[0037] The personnel carrying mechanism 28 includes a carrying plate 281; illustratively, as Figure 3 shown.

[0038] A first hanging rope ring 282 is provided on one side wall of the bearing plate 281, and a second hanging rope ring 283 is provided on the other side wall of the bearing plate 281. The first hanging rope ring 282 is connected to the end of the traction rope. The top and bottom of the bearing plate 281 are provided with a sitting arc groove 284. A pull-out plate 285 is slidably connected to one side wall of the bearing plate 281. Two groups of screw rods 286 are transversely threadedly connected to the bearing plate 281, and the two groups of screw rods 286 are symmetrically arranged with the central axis of the pull-out plate 285 as the center. The two groups of screw rods 286 are symmetrically arranged with the central axis of the pull-out plate 285 as the center. One end of the rod 286 is transmission-connected to the output end of the motor 287, and the two groups of motors 287 are fixedly connected to the first linkage ring 288 on the side away from the output end, and the first linkage ring 288 is rotatably connected to the outer wall of the sleeve 26, and the two groups of screw rods 286 are rotatably connected to the first moving wheel 289 on the side close to the motor 287, and the two groups of screw rods 286 are rotatably connected to the second moving wheel 2810 on the side away from the motor 287, and the two groups of screw rods 286 are rotatably connected to the linkage rod 2811 on one end close to the second moving wheel 2810.

[0039] Specifically, the sitting arc groove 284 is used for construction workers to sit on different surfaces of the bearing plate 281, and the pull-out plate 285 is moved to the feet of the construction workers, which is used to exert muscle pressure on the feet of the construction workers after sitting, so that the construction workers can perform long-term repair operations on the roof of the factory building 1 in a relaxed state, and the removed pull-out plate 285 can also be used to place the construction workers' repair tools and repair materials, which can move synchronously with the bearing plate 281, so as to facilitate the repair of different roof positions;

[0040] The output end of the motor 287 drives the screw rod 286 to rotate, so that the bearing plate 281 performs longitudinal construction operations on the top roof of the factory building 1 at different positions. The traction ropes in the first guide wheel 25 and the second guide wheel 27 can also be taken out, and the two groups of traction ropes are respectively connected to the first hanging rope ring 282 and the second hanging rope ring 283, so that the ends of the two groups of traction ropes extend to the vicinity of the first climbing ladder 23 and the second climbing ladder 24, so that the other two construction workers can use the bearing plate 281 to perform horizontal construction operations on the top roof of the factory building 1 at different positions while pulling the traction rope on one side, thereby reducing the self-traction of the construction workers;

[0041] When the first linkage ring 288 is rotatably connected to the outer wall of the sleeve 26, the two surfaces of the bearing plate 281 can be freely switched to different positions on the roof of the factory building 1 for coordinated use, so that the first moving wheel 289 and the second moving wheel 2810 can be adaptively rolled and fitted to different directions of the roof of the factory building 1.

[0042] The waste conveying mechanism 29 includes a guide track 291; illustratively, Figure 4 shown.

[0043] The upper and lower sides of the material guide track 291 are both open structures, and a material guide cavity 292 is opened on the material guide track 291. The inner wall of the material guide cavity 292 is fixedly connected with an isolation plate 293, and the central axis of the isolation plate 293 coincides with the central axis of the material guide track 291. One end of the material guide track 291 is fixedly connected with a second linkage ring 294, and the second linkage ring 294 is rotatably connected to the outer wall of the sliding sleeve 26. A first lower hopper 295 and a second lower hopper 296 are provided on the other side of the end of the material guide track 291. The first lower hopper 295 and the second lower hopper 296 are both communicated with the material guide cavity 292, and one side wall of the material guide track 291 is fixedly connected to the first hanging rope ring 282.

[0044] Specifically, the material guide track 291 is fixedly connected to the first hanging rope ring 282, and is used for the synchronous linkage of the material guide track 291 and the supporting plate 281. The waste remaining in the roof repair process is put into the material guide cavity 292 by utilizing one side of the isolation plate 293 on the material guide cavity 292, and slides into the first lower hopper 295, so that the waste remaining on the roof can fall safely to a designated position, avoiding the safety hazard caused by the waste falling from a high altitude. After the second linkage ring 294 rotates, the second lower hopper 296 moves to the other side of the roof, which can also make the waste remaining on the roof fall safely to a designated position.

[0045] The working principle of a safety protection device for roof construction proposed by the embodiment of the present invention is as follows:

[0046] The inner tube 22 is slidably connected to the outer tube 21, and the inner tube 22 is used to adjust the telescopic distance during the sliding process to meet the needs of factories with different lengths. The first climbing ladder 23 is mounted on one end of the outer tube 21, and the second climbing ladder 24 is mounted on one end of the inner tube 22. The first climbing ladder 23 is used for construction workers to climb into the personnel carrying mechanism 28, and the second climbing ladder 24 is used to facilitate the personnel on the personnel carrying mechanism 28 to leave the roof of the factory building 1 after the construction is completed;

[0047] The sitting arc groove 284 is used for construction workers to sit on different surfaces of the bearing plate 281, and the pull-out plate 285 is moved to the feet of the construction workers to exert muscle pressure on the feet of the construction workers after they sit, so that the construction workers can perform long-term repair operations on the roof of the factory building 1 in a relaxed state. The removed pull-out plate 285 can also be used to place the construction workers' repair tools and repair materials, which can move synchronously with the bearing plate 281 to facilitate the repair of different roof positions;

[0048] In the process of driving the screw rod 286 to rotate through the output end of the motor 287, the bearing plate 281 performs longitudinal construction operations on the top roof of the factory building 1 at different positions. The traction ropes in the first guide wheel 25 and the second guide wheel 27 can also be taken out, and the two groups of traction ropes are respectively connected to the first hanging rope ring 282 and the second hanging rope ring 283, so that the ends of the two groups of traction ropes extend to the vicinity of the first climbing ladder 23 and the second climbing ladder 24, so that the other two construction workers can use the bearing plate 281 to perform horizontal construction operations on the top roof of the factory building 1 at different positions while pulling the traction rope on one side, thereby reducing the self-traction of the construction workers;

[0049] The guide rail 291 is fixedly connected to the first hanging rope ring 282, and is used for the synchronous linkage of the guide rail 291 and the supporting plate 281. The waste remaining in the roof repair process is put into the guide cavity 292 by utilizing one side of the isolation plate 293 on the guide cavity 292, and slides into the first lower hopper 295, so that the waste remaining on the roof can fall safely to the designated position, avoiding the safety hazard caused by the waste falling from a high altitude. After the second linkage ring 294 rotates, the second lower hopper 296 moves to the other side of the roof, which can also make the waste remaining on the roof fall safely to the designated position.
