Problems solved by technology

At present, most elevator counterweights are made of cast iron, which is bulky, difficult to install, and high in cost. Some elevator counterweights are made of concrete blocks, and the sides are wrapped with iron sheets, but the upper and lower surfaces are wrapped with iron sheets, which is easy to weather and change due to moisture. The weight of the counterweight affects the traction capacity of the elevator, the strength is not high enough, and the combination of multiple counterweights will generate noise during movement

Abstract

The invention provides a combined counterweight block used for an elevator. The combined counterweight block comprises a counterweight frame and a plurality of composite counterweight block bodies arranged in the counterweight frame. Each counterweight block body is composed of, by weight, 34-46 parts of iron tailings, 23-36 parts of steel slag, 22-31 parts of barite, 32-50 parts of cement, 2-10 parts of rattan, 3-9 parts of wicker, 0-2 parts of PVC and 2-3 parts of plastic. According to the combined counterweight device, casting is completed by adopting the iron tailings, the steel slag, the barite and the cement, and the rattan, the wicker, the PVC and the plastic are added, so that the pulling strength among the counterweight block bodies is improved, and the service life is prolonged; and in addition, the problem that the noise of the counterweight device is too large in the movement process is solved.

Description

technical field [0001] The invention relates to a counterweight, in particular to a combined counterweight for an elevator. Background technique [0002] The counterweight is an integral part of the elevator drive system, and its function is to balance the weight of the car. At present, most elevator counterweights are made of cast iron, which is bulky, difficult to install, and high in cost. However, some elevator counterweights are made of concrete blocks, and the sides are wrapped with iron sheets, but the upper and lower surfaces are wrapped with iron sheets, which is easy to weather and change due to moisture. The weight of the counterweight affects the traction capacity of the elevator, the strength is not high enough, and the combination of multiple counterweights will generate noise during movement. Contents of the invention [0003] In order to solve the above problems, the present invention provides a combination counterweight with low cost and high strength. ...
