Elevator synthetic counterpoise and its manufacturing method

Abstract

One kind of synthetic counter-weight block and its manufacture method, which prepares one outer covering by the metal or the plastic, the outer covering internal installation has metal material, the metal material and its waste residue, as well as the inorganic material mix and is solid with the cementing agent for one body core body (packing) composes, its characteristic is: The steel plate system outer covering 4 - 10%, outside the shell the spreading guards against the rust paint is 0.1%; Other for packing, steel slag 50 - 70%, steel bar 1 - 3%, cement 8 - 15%, powdered iron 5 - 19%, water composition3 - 5% ; The steel bar is curved to two rectangular shapes, horizontal puts packing on two stratification planes, plays the role of reinforcement. This counter-weight block may completely substitute the original craft which is backward. The waste steel and iron can be used as the steel-making for packing, whose material originates broadly, the cost falls above 1 / 3, the manufacture simple easy line, good structure compact intensity and has the characteristic of environmental protection.

Description

technical field [0001] The invention relates to a counterweight, more specifically to an elevator synthetic counterweight and a manufacturing method thereof. It belongs to the technical field of elevator accessories. Background technique [0002] Most of the existing elevator counterweights are cast by small factories using pure metal materials such as iron, steel, and lead. The casting technology is backward, the process is complicated, and it is easy to break during on-site installation. Elevator costs keep rising. In the past two years, people have sought to replace pure metal counterweights with new composite materials. After retrieving Chinese patents, there are the following four documents involving different counterweights, and the patent application numbers are: 200410019011.0; 200410026571.9; 200410020828.X; 200410050240.9. Some of them use: natural heavy metals; steel scrap / iron pellets; rolled steel powder; and are equipped with cement, sand, water, and adhesiv...

AI Technical Summary

Problems solved by technology

The use of steel scrap / iron pellets and rolling powder also has problems such as high cost and limited source of materials

In addition, the counterweight without a shell is very easy to break; some cores are also easily broken due to poor density, so they are not suitable for elevator counterweights.

In conclusion, these inventions cannot be used as a substitute for the weight of the elevator
