Counterweight frame with gravity center adjustable

Abstract

The invention discloses a counterweight frame with a gravity center adjustable. The counterweight frame comprises a guide shoe, a guide shoe rotating connection seat, a first counterweight frame, a second counterweight frame, counterweight frame connecting pieces and a compensation rope head supporting piece, wherein the guide shoe is fixedly connected with the guide shoe rotating connection seatthrough a support, the inner wall of the guide shoe rotating connection seat is fixedly connected with the counterweight frame connecting pieces, and the counterweight frame connecting pieces are arranged at the two ends of the first counterweight frame and the second counterweight frame. According to the counterweight frame with the gravity center adjustable, long holes which are regularly distributed are formed in the side walls of the two counterweight frames, counterweight block fastening devices are connected with the long holes through locking screws, the weight of counterweight blocks which are connected with the counterweight block fastening devices can be controlled by installing the counterweight block fastening devices at the long holes at different positions, so that the overall weight distribution can be conveniently adjusted; and meanwhile, the compensation rope head supporting piece is connected with the first counterweight frame and the second counterweight frame through bolts, the position of the compensation rope head supporting piece can be adjusted, so that the overall weight balance is further controlled, and the operation of the elevator is stable.

Description

technical field [0001] The invention relates to the technical field, in particular to a counterweight frame with an adjustable center of gravity. Background technique [0002] The speed of the elevator generally increases with the increase of the total height of the building. When the building is very high, the weight change of the wire rope of the elevator traction system cannot be ignored, which will affect the balance of the system and thus affect the comfort of the elevator. Generally, compensation Chains or compensation wire ropes are used to balance the quality of the system, and generally compensation chains or compensation wire ropes are installed at the center of gravity of the counterweight system (usually at the bottom center of the counterweight system), which will affect the buffer at the bottom of the counterweight frame or have The installation of devices such as counterweight safety gear, but the weight balance adjustment process of the existing elevator coun...
