The invention relates to the technical field of elevator equipment, in particular to a lifting capacity limiting device of a construction elevator, which comprises a base, a mounting seat is fixed on the surface of the front side of the base, side frames are symmetrically fixed on two sides of the upper surface of the base, and a controller and an alarm are respectively fixed on the surface of the side frame on one side. A mounting table is fixed to the middle of the upper surface of the base. When the value of pressure borne by the pressure sensor reaches a preset value, the pressure sensor sends a signal to the controller, then the controller controls the alarm to give an alarm, meanwhile, the controller controls the motor to work and drives the rotating shaft and the cam to rotate, and the protruding end of the cam makes contact with and extrudes the surface of the end cap. At the moment, the end cap overcomes the elastic force of the spring D and pushes the guide rod to slide towards the inner side of the limiting seat, and then the end part of the guide rod is clamped into the limiting clamping groove, so that the hoisting basket cannot be randomly lifted, an operator is effectively prevented from illegally operating the hoisting basket to carry out overload lifting, and safety accidents are avoided to a certain extent.
本发明涉及升降机设备技术领域,具体为一种施工升降机的起重量限制装置,包括底座,所述底座前侧表面固定有安装座,所述底座上表面两侧对称固定有侧架,一侧所述侧架表面分别固定有控制器和报警器,所述底座上表面中间处固定有安装台。本发明中压力传感器所受压力值达到预定值时,压力传感器将向控制器发送信号,随后控制器将控制报警器发出警报,同时控制器将控制电机工作并带动转轴及凸轮转动,且凸轮凸起端将接触并挤压端帽表面,此时端帽将克服弹簧D弹力并推动导动杆向限位座内侧滑动,进而导动杆端部将卡入限位卡槽内部,使得起重篮不能随意升降,进而有效避免了操作员违规操作起重篮进行过载升降,一定程度上避免了安全事故的发生。
