Problems solved by technology

[0004] Problems existing in the existing balance compensation chain: the elevator balance compensation chain is covered with electric welding anchor chain and composite material, but generally the bending diameter is not controlled, resulting in a systematic problem of the compensation chain suspension, that is, the compensation chain cannot form a natural shape due to the too small bending diameter. Vertical motion curve, the compensation chain will deflect to the guide wheel during motion to form motion resistance and reduce the service life of the product

Abstract

The invention discloses a balance compensation chain suitable for wide-car elevators and a preparation process thereof, belonging to the technical field of elevator balance compensation chains, and a balance compensation chain suitable for wide-car elevators and a preparation process thereof, including compensation chains , Suspension device and preparation process, the outer wall of the compensation chain chain is provided with an outer cladding layer, the material of the outer cladding layer is environmentally friendly polyvinyl chloride, and the outer cladding layer is coated on the compensation chain chain through multi-channel extrusion molding of a single-screw extruder. Suspension device comprises connecting rope and connecting head. It can improve the service life of the compensation chain, and is equipped with a supporting suspension device to perform secondary protection on the compensation chain, and through the automatic coiling device, the chain and the outer cladding of the compensation chain are automatically coiled, with good coiling effect and high efficiency. The wear is small, so that the compensation chain maintains a large radius of cooling and shaping, thereby increasing the bending diameter of the compensation chain, so that the compensation chain can form a natural vertical motion curve.

Description

technical field [0001] The invention relates to the field of elevator balance compensation chains, in particular to a balance compensation chain suitable for wide-car elevators and a preparation process thereof. Background technique [0002] With the development of the elevator industry, some elevator manufacturers have developed wide-body car elevators with rectangular boxes to meet the requirements of intelligent transportation in modern buildings. The advanced elevator balance compensation chain system ensures stable and reliable operation, and at the same time solves the dynamic balance problem during the elevator lifting process. [0003] The balance compensation chain is often used in car elevators, and is mainly used to compensate the weight of the wire rope to make the elevator run smoothly. When the elevator is on the top floor, the steel wire rope is on the counterweight side, and the weight of the steel wire rope is on the counterweight side; when the elevator is...
