Problems solved by technology
Because this counterweight method only considers the stress on the guide shoe at a certain position of the elevator, it cannot guarantee that the force on the guide shoe in the whole elevator can meet the design requirements of the guide shoe itself. In addition, the force on the guide shoe changes with the elevator height. In a wide range of repeated changes, this will seriously affect the service life of the guide shoe

The invention discloses a weight balancing device of an elevator compensating bar structure. The weight balancing device and the compensating bar structure are respectively arranged at both sides of a car frame center at the bottom of an elevator car; the weight balancing device comprises a bracket arranged at the bottom of an elevator car; the bracket is provided with a balance weight and a balance weight position adjusting mechanism, and the balance weight position adjusting mechanism drives the balance weight to move horizontally in order to adjust the horizontal distance from the balance weight to the car frame center. The invention is provided with the balance weight which can be used for adjusting the horizontal position to balance the weight of the compensating bar structure in real time so as to adjust the impact of the weight of the compensation bar structure on guide shoes, thereby prolonging the service life of the guide shoes and improving comfortableness on taking an elevator.
Description
technical field [0001] The invention relates to a weight balance device, in particular to a weight balance device with an elevator compensation bar structure, and belongs to the technical field of traction elevators. Background technique [0002] High-speed elevators are generally used in high-rise buildings, and their lifting heights are generally high. Due to the high speed, it is necessary to configure a compensation device such as a suspension compensation strip structure to compensate for changes in the weight of the traction wire rope and accompanying cables, thereby reducing The impact of changes in the weight of the traction wire rope and accompanying cable on the entire elevator traction system. Most of the compensation strip structures are compensation ropes, compensation chains or compensation cables, and the compensation rope is the most common compensation strip structure for high-speed elevators. The rope will be heavier. Due to the layout of the elevator sha...
