Description

Technical Field

[0001] The utility model relates to the technical field of building construction equipment, in particular to an attached lifting device with an anti-fall protection function. Background Art

[0002] The integral lifting scaffolding is a special scaffolding structure. By using an electric hoist as the lifting power equipment, the entire scaffolding can climb up or down along the outer wall or column of the building. This scaffolding has the advantages of good overall structure, quick and convenient lifting, high degree of mechanization and significant economic benefits. When using the integral lifting scaffolding, if no fall protection equipment is used, there is a certain safety risk. Once an accident occurs and the frame falls, it will cause a serious accident.

[0003] The existing anti-falling device is provided with a clutch device between the anti-falling positioning wheel body and the anti-falling positioning wheel axle seat. When the scaffold is slowly lifted or lowered, if the frame body suddenly falls, the anti-falling positioning wheel will produce a reverse rotation speed. At this time, the automatic trigger will trigger the operation of the clutch device, so that the clutch device works. The function of the clutch device is to prevent the anti-falling positioning wheel from continuing to rotate in the opposite direction. It will jam the spaced cross bars set on the guide rail, thereby preventing the scaffold from continuing to fall.

[0004] However, the above-mentioned clutch device has a complex structure and requires precise manufacturing and assembly of various components to ensure its reliability and normal operation, which requires a higher level of technology and stricter quality control, increasing the difficulty of manufacturing and maintenance. At the same time, the clutch device requires workers to perform manual operation to trigger its working mechanism, which requires workers to receive relevant training to ensure the correct operation method; in view of this, we propose an attached lifting device with anti-fall protection function. Utility Model Content

[0005] The purpose of the utility model is to provide an attached lifting device with an anti-fall protection function to solve the problems raised in the above background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: an attached lifting device with anti-fall protection function, comprising an attached lifting scaffold, a traction rope is fixedly connected to the top end surface of the attached lifting scaffold, and an anti-fall protection component is arranged at one end of the traction rope away from the attached lifting scaffold, and the anti-fall protection component comprises:

[0007] A bracket, wherein the inner wall of the bracket is fixedly connected to a shell, the side wall of the shell is fixedly connected to a motor, and the output shaft of the motor is fixedly connected to a winding roller;

[0008] A limiting rod, the inner wall of the shell is fixedly connected to the limiting rod, and the side wall of the limiting rod is fixedly connected to a magnet;

[0009] A movable plate, wherein the outer wall of the winding roller is fixedly connected with a mounting seat, the side wall of the mounting seat is hinged with a movable plate, and a clamping groove is provided on the end surface of the movable plate;

[0010] A rotating rod is sleeved on the inner wall of the winding roller, the rotating rod is fixedly connected to the handle, a connecting rope is fixedly connected to the side wall of the rotating rod, and one end of the connecting rope away from the rotating rod is fixedly connected to the movable plate.

[0011] Preferably, a magnetic member is fixedly connected to the outer wall of the mounting seat.

[0012] Preferably, the width of the card slot is matched with the width of the limiting rod, and the card slot is plugged into the limiting rod.

[0013] Preferably, the magnetic member is magnetically connected to the movable plate, and the movable plate is magnetically connected to the magnet.

[0014] Preferably, one end of the traction rope away from the attached lifting scaffold is wound around the outer wall of the winding roller, and the motor is started to drive the winding roller to rotate, thereby winding the traction rope.

[0015] Preferably, the bracket is installed on the stairs and the scaffolding, and the bracket is located above the attached lifting scaffolding. When the attached lifting scaffolding falls, the bracket is pulled up to prevent it from falling.

[0016] Compared with the prior art, the utility model provides an attached lifting device with anti-fall protection function, which has the following beneficial effects:

[0017] 1. The attached lifting device with anti-fall protection function is provided with a winding roller, a movable plate, a slot, a limit rod and a magnet. When the attached lifting scaffolding suddenly falls, the centrifugal force brought by the rapid rotation of the winding roller throws the movable plate out, and the limit rod is stuck in the slot on the movable plate, thereby preventing the rotation of the winding roller, so that the attached lifting scaffolding stops, and the attached lifting scaffolding is braked. The braking function is achieved by mechanical principles, and does not rely on electronic or hydraulic systems. Therefore, it has higher reliability and reduces the complexity and manufacturing cost of the braking device. After the limit rod is stuck in the movable plate, the movable plate is magnetically connected to the magnet, thereby preventing the movable plate from resetting after braking. Because the construction personnel have not come down from the attached lifting scaffolding after braking, the provided magnet ensures that even if the brake is released, the scaffolding will not immediately resume movement, providing additional safety protection for the construction personnel.

[0018] 2. The attached lifting device with anti-fall protection function is provided with a magnetic part, which magnetically attracts the movable plate to the outer wall of the mounting seat. When the lifting scaffolding suddenly falls, the centrifugal force caused by the instantaneous rotation will be greater than the magnetic attraction force of the magnetic part on the movable plate. By using the magnetic part to magnetically connect the movable plate to fix it during normal operation, the stability of the scaffolding can be ensured, providing more stable safety protection.

[0024] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: an attached lifting device with an anti-fall protection function, comprising an attached lifting scaffold 1, a traction rope 2 is fixedly connected to the top end surface of the attached lifting scaffold 1, and an anti-fall protection component is arranged at one end of the traction rope 2 away from the attached lifting scaffold 1, and the anti-fall protection component comprises a bracket 3, a shell 4, a motor 5, a winding roller 6, a mounting seat 7, a movable plate 8, a slot 9, a limit rod 10, a magnet 11, a rotating rod 12, a connecting rope 13, a handle 14, and a magnetic part 15.

[0025] In one embodiment of the utility model, the bracket 3 is installed on the stairs and the scaffolding, and the bracket 3 is located above the attached lifting scaffolding 1. When the attached lifting scaffolding 1 falls, it is pulled to prevent it from falling. The inner wall of the bracket 3 is fixedly connected with the shell 4, and the side wall of the shell 4 is fixedly connected with the motor 5. The output shaft of the motor 5 is fixedly connected with the winding roller 6. The end of the traction rope 2 away from the attached lifting scaffolding 1 is wound around the outer wall of the winding roller 6. The motor 5 is started to drive the winding roller 6 to rotate, and then the traction rope 2 is wound. The inner wall of the shell 4 is fixedly connected with the limit rod 10, and the side wall of the limit rod 10 is fixedly connected There is a magnet 11, the outer wall of the winding roller 6 is fixedly connected to the mounting seat 7, the side wall of the mounting seat 7 is hinged with a movable plate 8, the movable plate 8 is magnetically connected to the magnet 11, and a slot 9 is provided on the end face of the movable plate 8. The width of the slot 9 is adapted to the width of the limiting rod 10, the slot 9 is plugged into the limiting rod 10, the outer wall of the mounting seat 7 is fixedly connected to a magnetic member 15, the magnetic member 15 is magnetically connected to the movable plate 8, the inner wall of the winding roller 6 is sleeved with a rotating rod 12, the rotating rod 12 is fixedly connected to the handle 14, the side wall of the rotating rod 12 is fixedly connected to a connecting rope 13, and the end of the connecting rope 13 away from the rotating rod 12 is fixedly connected to the movable plate 8.

[0026] When the attached lifting scaffold 1 is used, the motor 5 controls the traction rope 2 to move up and down synchronously with the attached lifting scaffold 1. When the attached lifting scaffold 1 suddenly falls, the fall drives the traction rope 2 to fall rapidly, further drives the winding roller 6 to rotate rapidly, and the centrifugal force caused by the rapid rotation of the winding roller 6 throws the movable plate 8 out, and the limit rod 10 is stuck in the slot 9 on the movable plate 8, thereby preventing the rotation of the winding roller 6, so that the attached lifting scaffold 1 stops, and the attached lifting scaffold 1 is braked. The braking function is realized by mechanical principles and does not rely on electronic or hydraulic systems. Therefore, it has higher reliability and reduces the complexity and manufacturing cost of the braking device. After the limit rod 10 is stuck in the movable plate 8, the movable plate 8 is magnetically connected to the magnet 11, thereby preventing the movable plate 8 from resetting after braking. Since the construction personnel have not come down from the attached lifting scaffold after braking, the magnet 11 is set to ensure that even if the brake is released, the scaffold will not immediately resume movement, providing additional safety protection for the construction personnel.

[0027] In addition, a magnetic component 15 is fixedly connected to the outer wall of the mounting base 7. When the motor 5 drives the winding roller 6 and the movable plate 8 to rotate normally, the magnetic component 15 magnetically attracts the movable plate 8 to the outer wall of the mounting base 7. When the lifting scaffold 1 suddenly falls, the centrifugal force caused by the instantaneous rotation will be greater than the magnetic attraction force of the magnetic component 15 on the movable plate 8. By using the magnetic component 15 to magnetically connect the movable plate 8 to fix it during normal operation, the stability of the scaffold can be ensured and more stable safety protection can be provided.

[0028] When the motor 5 drives the winding roller 6 and the movable plate 8 to rotate normally, the magnetic part 15 magnetically attracts the movable plate 8 to the outer wall of the mounting seat 7, thereby ensuring the normal operation of the attached lifting scaffold 1 and preventing the emergency brake from being triggered by mistake.
