Alarming type constant force spring hanger

Abstract

The invention discloses an alarming type constant force spring hanger comprising a barrel internally provided with a pull rod. One end of the pull rod is located in the barrel. The other end of the pull rod extends out of the barrel. A pull plate is arranged at the end, located in the barrel, of the pull rod. A plurality of belleville springs are arranged on one side, toward the bottom end of thebarrel, of the pull plate. Adjacent belleville springs are arranged reversely. The outer walls of the belleville springs with openings toward the bottom end of the barrel are each provided with a plurality of uprights. Pressure sensors are arranged at the top ends of the uprights and are internally provided with Bluetooth emitters. A buzzer is arranged on the outer wall of the barrel and is internally provided with a Bluetooth receiver. The pressure sensors transmit the received pressure values to the buzzer through the Bluetooth emitters. The buzzer sets a start pressure value. When the buzzer receives the pressure values which come from the pressure sensors and are larger than the start pressure value, the buzzer starts and makes a noise. When overloading occurs to the alarming type constant force spring hanger, alarming is conducted in time, and overloading operation is avoided.

Description

technical field [0001] The invention relates to an alarm type constant force spring hanger, belonging to the technical field of constant force spring hangers. Background technique [0002] The traditional constant force spring hanger uses the internal elastic element to play a supporting role. The upper end is hooked on the lifting structure, and the lower end is hooked to the heavy object to be lifted. When the hooked heavy object exceeds the carrying capacity of the elastic element, it is easy to cause The elastic element overload fails, making the constant force spring hanger invalid. Contents of the invention [0003] In order to solve the above-mentioned problems, the present invention discloses an alarm type constant force spring hanger, and its specific technical scheme is as follows: [0004] The alarm type constant force spring hanger includes a cylinder body, one end of the cylinder body is integrally formed with the cylinder body, and a hanging ear is arranged ...
