Description

Technical Field

[0001] The utility model relates to the technical field of construction safety protection, in particular to a safety rope locking and protection device for high-rise building construction. Background Art

[0002] At present, a safety rope is an auxiliary rope used to connect a safety belt, which is used to ensure the safety of high-altitude construction workers. All high-altitude construction workers need to additionally bind a safety rope, and the safety status of this safety rope occupies a relatively large proportion in high-altitude construction.

[0003] In the prior art, a safety rope locking and protection device usually has a clockwork spring, a wire reel and a fixed shaft, which can automatically retract the safety rope during high-rise building construction by personnel, thus effectively avoiding the influence of redundant safety ropes on the construction work of workers; moreover, through the setting of a ratchet wheel, a ratchet pawl and a slider, etc., the switch can be opened or closed according to the use requirements of construction workers, so that the relaxation or locking of the pulling rope can be flexibly adjusted, and thus it is convenient for construction workers to use according to their own situations.

[0004] However, the inventor of the present application found that when a construction worker accidentally falls, the above device will stop retracting and releasing emergently, but the impact force of the sudden stop will cause no small harm to the body of the construction worker, so its functionality still needs to be improved. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a safety rope locking and protection device for high-rise building construction, which can gradually reduce the speed of the emergency descent of construction workers, thus playing a good protective role and preventing the body from being severely impacted.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A safety rope locking and protection device for high-rise building construction, comprising: a mounting frame, a rope wheel is rotatably connected inside the mounting frame, and a mounting cylinder is fixedly connected to the center of one side of the outer wall of the mounting frame, the mounting cylinder is communicated with the mounting frame, a connecting shaft is fixedly connected to the center of the side of the rope wheel close to the mounting cylinder, and strip-shaped limiting grooves are formed on both sides of the outer wall of the connecting shaft, a moving shaft is slidably connected to the outer wall of the connecting shaft and the strip-shaped limiting grooves together, a buffer spring is fixedly connected to the end of the inner wall of the mounting cylinder far from the connecting shaft, and one end of the moving shaft is in contact with one end of the buffer spring;

[0008] One end of the outer wall of the moving shaft away from the buffer spring is fixedly connected with a circular ring. One side of the connecting shaft is rotatably connected with a threaded rod, and one side of the threaded rod is threadedly connected with a top plate. One side of the top plate is slidably connected with the inner wall of the mounting cylinder, and one end of the top plate away from the mounting cylinder is in contact with the bottom surface of the circular ring;

[0009] One side of the center of the rope pulley close to the connecting shaft is fixedly connected with a first gear. One side of the outer wall of the rope pulley close to the first gear is rotatably connected with a second gear, and the second gear meshes with the first gear.

[0010] During actual application, two hollow plates are fixedly connected to one end of the outer wall of the moving shaft away from the connecting shaft. Trigger plates are slidably connected inside the two hollow plates. Four touch sensors are fixedly connected to the inner wall of the mounting cylinder close to the two hollow plates, and an alarm lamp, a power supply box and a speaker are fixedly connected to one side of the outer wall of the mounting frame.

[0011] Among them, the power access ends of the alarm lamp, the speaker and the touch sensor are electrically connected to the power output end of the power supply box.

[0012] Specifically, the signal receiving ends of the alarm lamp and the speaker are electrically connected to the signal transmitting ends of the touch sensor.

[0013] Further, the mounting frame is a circular mounting frame, and a fixing ring is rotatably connected to the top of the outer wall of the mounting frame.

[0014] Furthermore, a safety rope is wound around the outer wall of the rope pulley, and one end of the safety rope extends out from the bottom of the mounting frame.

[0015] Compared with the prior art, the safety rope locking and protecting device for high-rise building construction of the present utility model has the following advantages:

[0016] In the safety rope locking and protection device for high-rise building construction provided by the present utility model, since a rope wheel is rotatably connected inside the installation frame, and a mounting cylinder is fixedly connected to the center of one side of the outer wall of the installation frame, the mounting cylinder is communicated with the installation frame, a connecting shaft is fixedly connected to the center of the side of the rope wheel close to the mounting cylinder, and strip-shaped limiting grooves are formed on both sides of the outer wall of the connecting shaft. A moving shaft is slidably connected to the outer wall of the connecting shaft and the strip-shaped limiting grooves together. One end of the inner wall of the mounting cylinder away from the connecting shaft is fixedly connected with a buffer spring, and one end of the moving shaft is in contact with one end of the buffer spring; at the same time, a ring is fixedly connected to the end of the outer wall of the moving shaft away from the buffer spring. One side of the connecting shaft is rotatably connected with a threaded rod, and a top plate is threadedly connected to one side of the threaded rod. One side of the top plate is slidably connected to the inner wall of the mounting cylinder, and the end of the top plate away from the mounting cylinder is attached to the bottom surface of the ring. Therefore, when the threaded rod rotates to drive the top plate to move upward, the upward movement of the top plate can drive the ring and the moving shaft to move, so that one end of the moving shaft jacks up the buffer spring, thereby playing a good role in buffering the impact force; in addition, since a first gear is fixedly connected to the center of the side of the rope wheel close to the connecting shaft, a second gear is rotatably connected to a position on one side of the outer wall of the rope wheel close to the first gear, and the second gear meshes with the first gear. Therefore, when the rope wheel rotates to drive the first gear to rotate, the first gear rotates to drive the second gear to rotate, so that the second gear can drive the threaded rod to rotate, so that the moving shaft moves upward; therefore, when a construction worker falls, during the descending process, the rope wheel rotates rapidly, the rope wheel drives the first gear and the connecting shaft to rotate, the first gear and the connecting shaft rotate to drive the second gear and the threaded rod to rotate. When the threaded rod rotates, the top plate jacks up the ring and the moving shaft to move to one end, so that the moving shaft jacks up the buffer spring, gradually reducing the rotation speed of the rope wheel, that is, the descending speed of the construction worker, thereby playing a role in protecting the staff and preventing their bodies from being severely impacted.

Detailed implementation mode

[0022] For the convenience of understanding, the safety rope locking and protecting device for high-rise building construction provided by the embodiment of the present utility model will be described in detail below in conjunction with the attached drawings of the specification.

[0023] The embodiment of the present utility model provides a safety rope locking and protecting device for high-rise building construction, as Figures 1 - 3 shown, including: an installation frame 1, a rope pulley 8 is rotatably connected inside the installation frame 1, and a center of one side of the outer wall of the installation frame 1 is fixedly connected with an installation cylinder 3. The installation cylinder 3 is communicated with the installation frame 1. A center of one side of the rope pulley 8 close to the installation cylinder 3 is fixedly connected with a connecting shaft 15, and strip-shaped limit grooves 17 are formed on both sides of the outer wall of the connecting shaft 15. A moving shaft 12 is slidably connected with the outer wall of the connecting shaft 15 and the strip-shaped limit grooves 17. One end of the inner wall of the installation cylinder 3 far from the connecting shaft 15 is fixedly connected with a buffer spring 9, and one end of the moving shaft 15 is in contact with one end of the buffer spring 9;

[0024] One end of the outer wall of the moving shaft 12 far from the buffer spring 9 is fixedly connected with a ring 18. One side of the connecting shaft 15 is rotatably connected with a threaded rod 19, and one side of the threaded rod 19 is threadedly connected with a top plate 13. One side of the top plate 13 is slidably connected with the inner wall of the installation cylinder 3, and one end of the top plate 13 far from the installation cylinder 3 is attached to the bottom surface of the ring 18;

[0025] A center of one side of the rope pulley 8 close to the connecting shaft 15 is fixedly connected with a first gear 16. One side of the outer wall of the rope pulley 8 close to the first gear 16 is rotatably connected with a second gear 14, and the second gear 14 meshes with the first gear 16.

[0026] Compared with the prior art, the safety rope locking and protecting device for high-rise building construction described in the embodiment of the present utility model has the following advantages:

[0027] In the safety rope locking and protection device for high-rise building construction provided by the embodiment of the utility model, since a rope wheel 8 is rotatably connected inside the installation frame 1, and a mounting cylinder 3 is fixedly connected to the center of one side of the outer wall of the installation frame 1, the mounting cylinder 3 communicates with the installation frame 1. A connecting shaft 15 is fixedly connected to the center of the side of the rope wheel 8 close to the mounting cylinder 3. Strip-shaped limiting grooves 17 are formed on both sides of the outer wall of the connecting shaft 15. A moving shaft 12 is slidably connected to the outer wall of the connecting shaft 15 and the strip-shaped limiting grooves 17. A buffer spring 9 is fixedly connected to the end of the inner wall of the mounting cylinder 3 far from the connecting shaft 15. One end of the moving shaft 12 is in contact with one end of the buffer spring 9. At the same time, a ring 18 is fixedly connected to the end of the outer wall of the moving shaft 12 far from the buffer spring 9. A threaded rod 19 is rotatably connected to one side of the connecting shaft 15. A top plate 13 is threadedly connected to one side of the threaded rod 19. One side of the top plate 13 is slidably connected to the inner wall of the mounting cylinder 3. The end of the top plate 13 far from the mounting cylinder 3 is in fit with the bottom surface of the ring 18. Therefore, when the threaded rod 19 rotates to drive the top plate 13 to move upward, the upward movement of the top plate 13 can drive the ring 18 and the moving shaft 12 to move, so that one end of the moving shaft 12 jacks up the buffer spring 9, thereby playing a good role in buffering the impact force. In addition, since a first gear 16 is fixedly connected to the center of the side of the rope wheel 8 close to the connecting shaft 15, a second gear 14 is rotatably connected to a position on the outer wall of the rope wheel 8 close to the first gear 16, and the second gear 14 meshes with the first gear 16. Therefore, when the rope wheel 8 rotates to drive the first gear 16 to rotate, the rotation of the first gear 16 drives the second gear 14 to rotate, so that the second gear 14 can drive the threaded rod 19 to rotate to move the moving shaft 12 upward. Therefore, when a construction worker falls, during the descending process, the rope wheel 8 rotates rapidly. The rope wheel 8 drives the first gear 16 and the connecting shaft 15 to rotate. The rotation of the first gear 16 and the connecting shaft 15 drives the second gear 14 and the threaded rod 19 to rotate. When the threaded rod 19 rotates, the top plate 13 jacks up the ring 18 and the moving shaft 12 to move to one end, so that the moving shaft 12 jacks up the buffer spring 9, gradually reducing the rotation speed of the rope wheel 8, that is, the descending speed of the construction worker, thereby playing a role in protecting the staff and preventing their bodies from being severely impacted.

[0028] During actual application, such as Figures 1 - 3As shown in the figure, at one end of the outer wall of the above-mentioned moving shaft 12 far from the connecting shaft 15, two hollow plates 11 are fixedly connected. Inside each of the two hollow plates 11, a trigger plate 10 is slidably connected. At positions on the inner wall of the installation cylinder 3 close to the two hollow plates 11, four touch sensors 20 can be fixedly connected. And on one side of the outer wall of the installation frame 1, an alarm lamp 6, a power supply box 5 and a horn 4 can be fixedly connected, so that the protection device has a rescue mechanism; when the connecting shaft 15 rotates, while the moving shaft 12 moves towards one end of the installation cylinder 3, it also rotates. The trigger plate 10 is slidably connected to the hollow plate 11. Due to centrifugal force, the trigger plate 10 is thrown out when the moving shaft 12 rotates, and at the same time, it can touch the touch sensor 20 on the inner wall of the installation cylinder 3. Thus, the alarm lamp 6 and the horn 4 start to work, and then sound and light signals are created, which is convenient for other workers to rescue the trapped personnel, making the protection device have better versatility.

[0029] Among them, as Figures 1 - 3 shown, the power access terminals of the above-mentioned alarm lamp 6, horn 5 and touch sensor 20 can be electrically connected to the power output terminal of the power supply box 5, so as to use the power supply box 5 to provide power for each component, without the need for an external power supply, which is more convenient.

[0030] Specifically, as Figures 1 - 3 shown, the signal receiving terminals of the above-mentioned alarm lamp 6 and horn 4 can be electrically connected to the signal transmitting terminal of the touch sensor 20. Thus, when falling, the moving shaft 12 rotates to throw out the trigger plate 10. When the trigger plate 10 triggers the touch sensor 20, the touch sensor 20 provides a signal to the alarm lamp 6 and the horn 4 and starts them, and then sound and light signals are created, which is convenient for other workers to rescue the trapped personnel.

[0031] Furthermore, as Figures 1 - 3 shown, the above-mentioned installation frame 1 can preferably be a circular installation frame, and at the top of the outer wall of the installation frame 1, a fixing ring 2 can be rotatably connected. Thus, the protection device is fixed near the construction site by using the fixing ring 2, and one end of the safety rope 7 extends out for adjustment during normal work, which is more user-friendly.

[0032] Even further, as Figures 1 - 3 shown, the outer wall of the above-mentioned rope pulley 8 can be surrounded by a safety rope 7, and one end of the safety rope 7 can extend out from the bottom of the installation frame 1. Thus, one end of the safety rope 7 extending out of the safety frame 1 can be fixed to the body of the construction worker, and at the same time, the middle part of the safety rope 7 is wound around the outer wall of the rope pulley 8 in a surrounding manner.

[0033] Next, with the help of the attached drawings, the usage steps of the safety rope locking and protection device for high-rise building construction provided by the embodiment of the present invention will be described in detail:

[0034] Step S1: During the descending process, the rope wheel 8 rotates rapidly. The rope wheel 8 drives the first gear 16 and the connecting shaft 15 to rotate. The rotation of the first gear 16 and the connecting shaft 15 drives the second gear 14 and the threaded rod 19 to rotate;

[0035] Step S2: When the threaded rod 19 rotates, the top plate 13 jacks up the ring 18 and the moving shaft 12 moves towards one end, causing the moving shaft 12 to jack up the buffer spring 9 and gradually reducing the rotation speed of the rope wheel 8;

[0036] Step S3: When the moving shaft 12 rotates, the trigger plate 10 is thrown out due to centrifugal force and can simultaneously contact the touch sensor 20 on the inner wall of the mounting cylinder 3, causing the alarm lamp 6 and the horn 4 to start working.

[0037] As described above, it is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
