Elevator traction belt and manufacture method thereof

Abstract

The invention discloses an elevator traction belt and a manufacture method thereof. The elevator traction belt is designed for solving the technical problems of poor traction force, relative sliding effect and abrasion effect and short service life of the existing similar product. The traction belt is composed of a plurality of single bodies and has the key point that each single body of a rubber and plastic covering layer is respectively provided with one strand of load bearing core wire; and one side surface of the single body is in a triangle bulge shape, and the other side surface symmetrical with the above side surface is in a trapezoidal boss shape. The manufacture method comprises the following step: causing one end of each of multiple strands of the load bearing core wires to pass through a fixed traction belt injection covering mold and a core wire positioning plate; respectively connecting two ends of the load bearing core wires with a finished product traction belt winding drum and a load bearing core wire winding drum; and leading the load bearing core wires to pass through the traction belt injection covering mold and cover the rubber and plastic covering layer, thus obtaining the finished product traction belt. The elevator traction belt has the advantages of reasonable design, simple structure, low abrasion rate, long service life, stable transmission effect, good traction force action effect and feasible manufacture method, is suitable to be served as the elevator traction belt to use and manufacture and is suitable for improving the structure of the similar products.

Description

technical field [0001] The invention relates to an elevator traction belt, in particular to an elevator traction belt and a manufacturing method thereof. Background technique [0002] Elevator is a kind of vertical elevator powered by electric motor. It is mainly used for multi-storey buildings to take people or carry goods. According to its structure, it can be divided into car-type elevator and step-type automatic elevator. The car-type elevator is mainly composed of a traction machine, guide rails, counterweight devices, safety devices, signal control systems, car and hall doors, driven wheels, reversing wheels, etc. The traction machine is the power equipment of the elevator. A traction wheel is provided, and a traction rope (a traction belt in the present invention) is hung on the traction wheel (drive wheel). At both ends of the traction rope (belt), a counterweight is hung at one end, and a car is hung at the other end. When the driving wheel is driven by the motor,...
