Problems solved by technology
At present, most elevator counterweights are made of cast iron, which has problems such as bulkiness, difficulty in installation, and high cost; while 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 are 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 discloses a high-strength counterweight filler for an elevator. The counterweight filler is characterized by being prepared from components in parts by weight as follows: 40-80 parts ofcement, 20-40 parts of steel slag, 10-22 parts of iron ore, 7-10 parts of an adhesive, 4-10 parts of a defoamer, 2-5 parts of an anti-crack agent, 4-7 parts of a concrete anti-crack densifier, 2-6 parts of a hardening agent, 2-6 parts of a concrete expansive agent, 2-8 parts of anorthite, 4-7 parts of hyalophane, 2-8 parts of nano-silica, 1-4 parts of lignin and 5-10 parts of water. According to the formula of the counterweight filler, resources are saved, lift strength between the counterweight fillers is increased, service life is prolonged, and too large noise in a motion process of a counterweight device is reduced.
Description
technical field [0001] The invention belongs to the technical field of elevator parts, and in particular relates to a counterweight block with high elevator service strength. 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 has problems such as bulkiness, difficulty in installation, and high cost; while 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 are 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 overcome the above-mentioned defects in the pr...
