Embodiment Construction

[0019] The implementation mode takes the working principle and assembly of the present invention as an example. like figure 1 , figure 2 As shown, the traction belt is composed of multi-strand steel wire ropes 101 coated with rubber and plastic materials 102 . The steel wire rope is woven by twisted high-strength thin steel wires, and multiple steel wire ropes are arranged equidistantly in the traction belt; the outer rubber and plastic material has the characteristics of high wear resistance and high friction coefficient, and its outer two sides are symmetrical. An arc with a radius greater than 50% of the spacing between the wire ropes. like image 3 As shown, one end of the traction belt is fixed, through two (or one) guide wheels 3, through the traction sheave 211 of the traction machine 2, through another guide wheel, and finally the other end of the traction belt is fixed. The guide wheel on one side of the traction machine hangs the counterweight 5, and the guide w...

Abstract

The invention relates to a traction belt structure for a lifting elevator, in particular to a traction belt for the lifting elevator and a transmission method. The traction belt structure is designed to perfect the widely-known flat traction belt structure. The design key points are as follows: two lateral surfaces of a rubber plastic material wrapped by a hoisting cable are provided with symmetrical circular arcs, the number of the circular arcs is equal to the number of strands of the hoisting cable, and the hoisting cable is connected with the rubber plastic material into a whole. The transmission method is as follows: the circular arcs of the rubber plastic material wrapped by the hoisting cable of the traction belt, the circular arc of a traction sheave and the circular arc of a guide wheel operate closely, and the tension of the traction belt in the length direction is converted into the centripetal force of the hoisting cable. The traction belt structure has a reasonably designed structure, good transmission safety, good stability, and feasible transmission method, lowers the manufacture cost of the traction machine, reduces the occupied space inside the building, and is particularly suitable for the elevator without an equipment room.

Description

technical field [0001] The invention relates to a traction belt structure of an elevator, in particular to a traction belt and a transmission method of an elevator. Background technique [0002] At present, most of the traction machines in the elevator industry use wire ropes for traction. According to my country's main elevator standard GB7588-2003 "Safety Code for Elevator Manufacturing and Installation", the diameter of the steel wire rope must be ≥ 8mm, and the diameter ratio of the traction sheave to the steel wire rope must be ≥ 40. In the case of the same load, a large traction wheel will require a large traction torque, and a large traction torque will require a large motor, which will increase the manufacturing cost of the traction machine and the occupation of building space. In order to change this situation, in recent years, a traction belt with a core inlaid with multiple steel wire ropes and a rubber and plastic material with wear resistance and high friction ...
