Special flat dragging tape for plastic-wrapping carbon fiber elevator

Abstract

The invention relates to a special flat dragging tape for a plastic-wrapping carbon fiber elevator and belongs to the technical field of an elevator. The special flat dragging tape is prepared according to the following steps: firstly, weaving multi-strand carbon fiber thin ropes into a carbon fiber flat tape with meshes; performing injection molding on the synthetic plastics and carbon fiber flat tape; wrapping the carbon fiber flat tape in the synthetic plastics; and forming an integrated body by the synthetic plastics in the meshes of the carbon fiber flat tape and the synthetic plastics wrapped on the upper, lower and peripheral surfaces of the carbon fiber flat tape. The special flat dragging tape provided by the invention has the advantages that the tensile strength is 7-10 times of that of a steel tape with the same cross section; the weight is light; the density is only 1 / 4 of that of a common steel wire; the cross section of the dragging tape is reduced by 65%; the anti-breaking tensile force is increased by 70%; the durability is excellent; compared with the steel tape of the common elevator, the service life of the special flat dragging tape is increased by 4 times; the plastic-wrapping dragging tape is in tight contact with a wheel; a contact surface pressure ratio is low; no dragging abrasion exists; the bending capacity of rope is increased; a diameter of a dragging wheel is reduced; the driving power of a host machine is lowered; the cost is saved; and the special flat dragging tape is an ideal dragging transmission tape for elevator.

Description

Technical field [0001] The invention relates to a flat traction belt dedicated for elevators, and belongs to the technical field of elevators. Background technique [0002] At present, the elevator traction belts are made of steel wire and plastic woven. Because the tensile strength of the steel wire has certain requirements, the weight and cost are increased. At the same time, the rigidity of the steel wire is limited by the degree of bending. The diameter of the wheel cannot be smaller than a certain range. Summary of the invention [0003] The purpose of the present invention is to provide a special flat traction belt for plastic-wrapped carbon fiber elevators. The plastic-wrapped traction belt has closer contact with the wheels, the contact surface ratio is lower, and the surface contact between the belt and the wheel replaces the point contact. Reduce noise, and at the same time, more contact surfaces bring a quieter and smoother elevator operation, which makes the service l...

Problems solved by technology

[0002] At present, the traction drive belts of elevators are all made of steel wire and plastic braiding. Since the tensile strength of the steel wire has certain requirements, it will increase the weight and cost. At the same time, the rigidity of the steel wire is limited by the degree of bending. The diameter of the wheel cannot be less than a certain range
