Combined self-assembling/disassembling balance-weight device

Abstract

The invention is a combined type self dismounting balance weight device, belonging to car lift weight balance device. The balance weight device is connected to the underpart of the revolving stage, the balance weight is assembled with assembling aperture, there has a balance weight assembling cylinder above the balance weight, and one end of the turning center of the revolving stage is connected to a localizing detector and central detector. The balance weight device detects the position of the cylinder through the central detector and the localization detector, ensures the orientation when the lift assembles and regulates the balance weight, guarantees the reliability of the balance weight assembly, the assembly operation curve character can be set through programmable controller, caters the demands to jiggling performance when assembling the balance weight. The invention upgrades the working speed, reduces the intensity.

Description

technical field [0001] The invention relates to a counterweight device of a truck crane, in particular to a combined self-detachable counterweight device. Background technique [0002] At present, the balance weight device used in truck cranes is generally a fixed balance weight. The balance weight is the crane counterweight, which is installed at the tail of one end of the turntable. When the truck crane is lifting with a medium-long arm and a large range, the stability of the crane itself will deteriorate, which will affect the lifting performance, and the performance of the main structural parts such as the boom cannot be fully utilized, and the lifting performance will decay quickly with the change of the arm length and amplitude. ; Medium and large tonnage cranes have a fixed balance weight for the load, which reduces the driving state of the vehicle, such as increasing the weight of the vehicle itself and increasing the height of the cente...
