Abstract

The invention provides a wide-body elevator balance compensation chain and a production process thereof. The wide-body elevator balance compensation chain comprises an anchor chain and a wrapping layer wrapping the outside of the anchor chain; the anchor chain comprises elements including Fe, C, Si, Mn, Cr, Mo, Ni and Al; the wrapping layer comprises raw materials including a styrenic block copolymer, a thermoplastic elastomer, inflaming retarding silicon master batches, an inrumescent flame retardant, a flame retardant synergist and a processing agent; and the wrapping layer and the anchor chain are poured together to form a solid overall piece. According to the wide-body elevator balance compensation chain, as for an elevator with the width larger than that of a normal elevator compartment, the noise during running is reduced, and the specific gravity with unit length is increased. The wrapping layer has the beneficial effects that softness is achieved, environmental stress cracking resistance is achieved, the hardness is high, the specific gravity is large, the resistance to effect of heat is good, the bending radius is larger than 800 mm, inflaming retarding is achieved, low smoke density is achieved, and aging resistance is achieved; the material hardness reaches 80-90 shore hardness, the anchor chain is high in strength and toughness, the bearing load of the balance compensation chain is large, and the safety performance of the elevators is effectively improved.

Description

technical field [0001] The invention relates to the technical field of elevator equipment, in particular to a wide-body elevator balance compensation chain with a large specificity per unit length and high strength and a production process thereof. Background technique [0002] At present, most elevators used in the market are traction elevators, which include a car, traction wire rope, counterweight and accompanying cables. During the operation of the elevator, the length of the wire ropes on the car side and the counterweight side is constantly changing, which causes the weight of the wire ropes on both sides of the traction sheave to change. Therefore, when the lifting height of the elevator exceeds a certain height, it is necessary to set a Parts with a certain weight to balance the weight change caused by the height change, this is the elevator balance compensation chain. In short, the elevator balance compensation chain is defined as a component used to connect the el...
