Problems solved by technology

[0005] The invention provides a counterweight system for elevators with a variable counterweight ratio. The technical problem to be solved is that the adjustment of the counterweight is relatively complicated, the adjustable range is low, and the counterweight is biased when it is lifted, and the time is long. Allows for easy tilting of the counterweight system rack

Abstract

The invention provides a variable counterweight ratio counterweight system used for an elevator. The variable counterweight ratio counterweight system used for the elevator comprises a fixing base, acounterweight fixing frame, a lifting platform fixing frame and a driving roller, wherein the counterweight fixing frame and the lifting platform fixing frame are fixed to the top of the fixing base;the back face of the counterweight fixing frame is fixedly connected with the front face of the lifting platform fixing frame; and the driving roller is rotationally connected to the top of the counterweight fixing frame through a supporting base. According to the variable counterweight ratio counterweight system used for the elevator, the overall counterweight is adjusted by adjusting the quantity of auxiliary balancing weights, the quantity of the auxiliary balancing weights can be fast adjusted through cooperation of steel ropes, elastic ropes and hanging hooks, the auxiliary balancing weights are stressed uniformly on the whole with cooperation of second connecting plates, jacking blocks and jacking grooves and can rise more steadily, the structure is simple, operation is convenient, and the system can meet the demand for lifting counterweighting of cargoes of various weights.

Description

technical field [0001] The invention relates to the technical field of lifting systems, in particular to a counterweight system for elevators with a variable counterweight ratio. Background technique [0002] Elevators, also known as elevators, vertical elevators, hoisting machinery or devices for platforms or semi-enclosed platforms that carry people or goods up and down vertical passages, are composed of platforms and equipment, motors, cables and other auxiliary equipment for manipulating them. It constitutes a whole, and is mainly used to transport goods up and down between various working floors; between three-dimensional garages and underground garages, high-rise buildings above the second floor, places where pits cannot be excavated, and occasions where the height of the top floor cannot meet the requirements, such as narrow spaces that are difficult to solve, the product The hydraulic system is equipped with anti-falling, interactive interlocking of the upper and low...
