AI Technical Summary

Technical Problem

The wheel design of the existing safety rope traction device for exterior wall cleaning is not convenient to disassemble. It causes damage to the rope friction during long-term use, reduces friction, affects the winding effect, poses safety hazards, and reduces the practicality of the device.

Method used

A safety rope traction device including a frame, a drive assembly, a cord wheel and a traction mechanism is designed. The traction mechanism realizes convenient disassembly and replacement of the rotor through the installation assembly and the disassembly assembly, ensuring that the rope maintains sufficient friction during traction.

Benefits of technology

Through convenient disassembly and replacement of the rotor, the friction of the rope during traction is maintained, the safety and practicality of the device are improved, and safety hazards caused by reduced friction are avoided.

Abstract

The utility model relates to the technical field of rope traction devices, and discloses a safety rope traction device for outer wall cleaning, which comprises a rack, a driving component is mounted on one side of the rack, a rope pressing wheel is rotatably mounted on the upper side of one end of the rack, and a traction mechanism for pulling a safety rope is mounted at one end, close to the rope pressing wheel, of the rack. The traction mechanism comprises a traction assembly used for winding a rope and two mounting assemblies used for dismounting and replacing the traction assembly, and according to the safety rope traction device for cleaning the outer wall, through the arrangement of the mounting assemblies and the dismounting assemblies, dismounting of the rotating wheel can be completed; then the rotating wheel provided with a new curved annular groove and a new spiral groove is installed, so that the rotating wheel can be replaced when the inner walls of the curved annular groove and the spiral groove are abraded and the friction force between the rope and the rotating wheel is reduced, and therefore, the friction force of the rope during traction can be better maintained; and the safety of the traction rope of the device is greatly improved.
