Abstract

The invention provides a detection system and method for a crane transmission mechanism, and a crane, and belongs to the technical field of detection. The transmission mechanism comprises a motor, a speed reducer and a winding drum, and the motor is used for driving the speed reducer to drive the winding drum to rotate. The system comprises a first detection unit which connected with the motor and used for detecting rotation information of the motor and sending the rotation information of the motor to a control unit; a second detection unit which is connected with the winding drum and used for detecting rotation information of the winding drum and sending the rotation information of the winding drum to the control unit; and a control unit which is used for determining a first comparison result of the rotation information of the motor and the rotation information of the winding drum based on the transmission ratio between the motor and the winding drum and determining whether the transmission mechanism breaks down or not according to the first comparison result. By means of the scheme, the state of the transmission mechanism is analyzed in a mutual correction mode, the advantages of being good in reliability and high in accuracy are achieved, effective input can be provided for safety limiting, and the safety of the transmission mechanism can be improved.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a detection system and detection method for a crane transmission mechanism and a crane. Background technique [0002] The transmission mechanism of the tower crane includes transmission components such as motors, couplings, reducers, drums, and wire ropes. If any of these transmission components fails, the transmission mechanism of the tower crane will not be able to provide effective transmission, causing the tower crane to move. risk. [0003] In response to the above problems, the industry generally uses the reel end as a position information monitoring device to limit the deceleration and stop of the hook movement. However, this type of technology depends on the integrity and effectiveness of the transmission link. If the transmission link is interrupted, the position monitoring device will not be able to obtain effective information input, and cannot normally restrict the...
