Synthesized counterweight filler

Abstract

The invention discloses a synthesized counterweight filler. The synthesized counterweight filler comprises, by weight, 1.5%-10% of metal fibers, 60%-80% of ore and metal slags and 10%-38.50% of cement, wherein the water cement ratio is 0.3-0.5. The synthesized counterweight filler is formed by mixing and pouring the metal fibers, the cement, the ore and metal slags and the like according to a certain weight proportion, and then the using strength and weight requirements of an elevator for the synthesized counterweight filler can be met; the metal fibers can replace an outer-layer iron shell and inner reinforcing steel bars of a traditional counterweight filler, on one hand, the steel using amount can be saved, the painting process of the outer-layer iron shell can be reduced, and the pollution to the working environment can be reduced, and on the other hand, the welding operation of the iron shell and the steel bars is not needed, and therefore the labor and manufacture cost for manufacturing the counterweight filler can be significantly lowered; in addition, the counterweight fillers in various shapes can be quickly manufactured through overall pouring molding of the materials and different pouring moulds, and therefore the working efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of elevator accessories, in particular to a synthetic counterweight. Background technique [0002] The elevator composite counterweight currently used in the market is mainly composed of shells, reinforced steel bars, concrete and other materials mixed and poured. Wherein the shell is made by welding iron plates, and the cavity of the iron plate of the shell is welded and fixed with a plurality of reinforcing steel bars for fixing, and then filled with concrete (including cement, ore, etc.) and poured into it. The outer shell and internal reinforcing steel bars of the above-mentioned synthetic counterweights are all for improving the compressive and impact resistance strength of the counterweights. The manufacturing process needs to consume more steel materials, and requires a lot of manual welding operations, and the labor cost and material cost are high. High, welding operation is not conducive to environ...
