Problems solved by technology

Existing counterweights generally use cast iron structures. Due to the continuous rise of iron ore prices in the market, the manufacturing cost of counterweights is also rising. Therefore, how to develop an improved countermeasure with low manufacturing cost and high strength requirements has become an important issue. Issues that the industry needs to solve urgently

Abstract

The invention discloses an improved elevator counterweight. The improved elevator counterweight comprises a frame (1). A plurality of layers of steel wire frames (2) are arranged in the frame (1). Theframe is further filled with stone-mixed soil blocks (3). The stone-mixed soil blocks comprise, by weight, 100 parts to 200 parts of cement, 20 parts to 50 parts of perlite, 30 parts to 40 parts of silica fume, 100 parts to 150 parts of gravelly soil, 10 parts to 30 parts of expanding agents, 30 parts to 60 parts of magnesium carbonate, 20 parts to 40 parts of bentonite, and 50 parts to 100 partsof metal slag. According to the improved elevator counterweight, the production cost is greatly reduced, the mechanical property is improved, and potential safety hazard is eliminated.

Description

technical field [0001] The invention relates to an elevator counterweight structure, in particular to an elevator counterweight filled with concrete blocks and belongs to the field of elevator manufacturing. Background technique [0002] The weight balance system of the elevator is generally composed of the car, traction rope, counterweight and compensation chain. Its function is to ensure that the traction transmission of the elevator is always stable during operation. The counterweight is the part that plays the main balancing role in the weight balance system. The counterweight and the car are respectively hung on one side of the traction rope. The weight of the counterweight is determined according to the rated load of the elevator, which is generally the weight of the car plus 50% of the rated load. Under this weight, the load difference on both sides of the traction rope changes within a small range, so as to achieve the purpose of smooth operation of the elevator. ...
