Abstract

The invention discloses an online monitoring system and method of the tower crane jacking state. The online monitoring system comprises a first vibration monitoring device installed on a balance arm, a second vibration monitoring device installed on a tower crane body, a third vibration monitoring device installed on a tower crane boom, and a jamming monitoring device installed on a jacking oil cylinder, wherein the first vibration monitoring device, the second vibration monitoring device, the third vibration monitoring device and the jamming monitoring device are respectively connected with a control alarming device. According to the online monitoring system and method of the tower crane jacking state, by adopting a multi-parameter jacking state online monitoring method namely whether the vibration load of the tower crane exceeds the safe value is monitored via monitoring the vibration acceleration of the balance arm, the tower crane body and the tower crane boom of the tower crane, and whether the tower crane generates jamming via monitoring the load of the jacking oil cylinder, the jacking abnormality is found out at the early stage, the motions of the jacking oil cylinder are controlled, and the safety of the jacking operation of the tower crane is improved.

Description

technical field [0001] The invention relates to an online monitoring system and a monitoring method for the jacking state of a tower crane, and the field of real-time monitoring of the jacking operation process of a tower crane. Background technique [0002] Tower cranes (hereinafter referred to as tower cranes) are one of the main construction machinery for modern industrial and civil buildings. It is mainly composed of underframe, tower body, balance arm, lifting arm, tower top and tie rods. Its working mechanism mainly includes: lifting mechanism, slewing mechanism, trolley traction mechanism, jacking mechanism, etc. Because the tower crane can be close to the building, its amplitude utilization rate can reach 80% of the full amplitude. Therefore, the use of tower cranes in high-rise building construction has always been in a leading position. As the construction of large-scale projects increases, higher and higher requirements are put forward for the height of the towe...
