Self-balancing glass lifting arm

Abstract

The invention discloses a self-balancing glass lifting arm. The self-balancing glass lifting arm comprises a lifting rod main beam, wherein transmission gears are arranged at the two ends of the interior of the lifting rod main beam; and the transmission end of a servo motor is in transmission connection with the adjacent transmission gear, a movable chain is arranged on the surfaces of the transmission gears, and a lifting hook is arranged at the lower end of a weighing sensor. The self-balancing glass lifting arm is used for sensing the weight of a suspended object at the front end through the weighing sensor when an auxiliary glass lifting arm of a window cleaning machine at the rated weight by means of mechanical and electrical integration design, a main control CPU drives the servo motor to rapidly move through calculation to drive a balancing weight (including a driving storage battery) to reach a proper position, low-speed fine adjustment is continuously carried out through numerical value feedback of a horizontal sensor, full-closed-loop control is realized, and if the weighing sensor at the weighing end finds that the weight of the suspended object is larger than an allowable load rated value of the mechanism, the mechanism can give an alarm and automatically switch to a waiting mode, so that the automatic balance problem of the lifting arm is solved.

Description

technical field [0001] The invention relates to the technical field of window cleaners, in particular to a self-balancing glass boom. Background technique [0002] With the development of society, there are more and more super high-rise buildings in major cities, and the subsequent work of curtain wall maintenance and replacement is also increasing. For some buildings with complex external walls (with concave shapes) When replacing the curtain wall, the original glass crane can no longer meet the maintenance work. Therefore, some auxiliary glass crane arms will be used to send curtain wall materials such as maintenance glass into the concave surface for maintenance and construction. [0003] However, the existing auxiliary boom has the defect of being unable to maintain the balance of the boom. After the hanging object is installed, the front end of the boom loses the balance weight, causing the boom to be in a tilted state, which greatly reduces the safety of construction. ...
