Problems solved by technology

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 problem affects the traction capacity of the elevator, and the strength is not high enough

Abstract

The invention provides a high-strength counterweight block for an elevator. The high-strength counterweight block for the elevator comprises a shell and a filling body. A cavity is formed in the shell. The filling body is arranged in the cavity and prepared from, by weight, 56-63 parts of concrete, 21-33 parts of iron tailing, 16-24 parts of barite, 2-15 parts of wicker and 5-9 parts of iron pyrite. The counterweight block is a composite counterweight block, the filling body is mounted in the cavity of the shell, the shell is a cast iron shell, and the filling body is prepared by compounding the concrete, the iron tailing, the barite, the iron pyrite and the wicker, so that materials are saved, and cost is low; and the wicker is additionally arranged in the filling body, so that the pulling strength of the counterweight block is improved, the strength is high, and the service life is prolonged.

Description

technical field [0001] The invention relates to a counterweight, in particular to a high-strength 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 problem affects the traction capacity of the elevator, and the strength is not high enough. Contents of the invention [0003] In order to solve the above problems, the present invention provides a counterweight with low cost, easy installation and high strength. [0004] In order to achieve the above object, the present invention is achieved t...
