Embodiment 1

[0020] Embodiment 1: As shown in Figure 1, the lifting cylinders 5, 6, 7, 8 are respectively arranged on the tops of the masts 9, 10, 11, 12, and are respectively connected with the girder 1 of the gantry crane through steel strands, thereby forming four a lifting point. Correspondingly, a long-distance sensor 21-24 is installed under each lifting point, and each long-distance sensor 21-24 measures the height of the lifting point in real time, and transmits the measured height to the main control cabinet through the laser signal communication line 25 26. An oil pressure sensor is installed on each oil cylinder, and the oil pressure sensor measures the status signal of each oil cylinder in real time, and transmits the status signal to the main control cabinet 26 through the oil pressure communication line 18, so that the main control cabinet can accurately monitor the load data according to the collected load data in real time. Adjust the load distribution of the individual po...

Abstract

The present invention belongs to the field of ship making technology, and is especially multiple-tower combining process for installing a gantry crane. The installation process includes the following steps: set several portal tower pairs beside the gantry crane and setting elevating oil cylinders in the tops of the portal tower pairs to form elevating points; setting long distance sensor and oil pressure sensor to each point, connecting the oil pressure sensors to the main control cabinet and the elevating oil cylinders to the pump station with proportional valve connected to the main control cabinet; setting some elevating point as the master control one and the others as the servo ones and setting oil cylinder position sensor and proportional valve in the master control point; and controlling the synchronous operations of all the elevating points with the main control cabinet until completing the installation process. The present invention has high safety and reliability.

Description

technical field [0001] The invention belongs to the technical field of ships, and in particular relates to a multi-tower combined installation method of a gantry crane. Background technique [0002] Gantry cranes are mainly used in the shipbuilding industry. As the lifting weight of gantry cranes increases, the weight of their own structures also increases accordingly. Meet the needs of actual installation and construction. Contents of the invention [0003] The object of the present invention is to provide a multi-tower combined installation method of a gantry crane. [0004] The multi-tower combined installation method of the gantry crane proposed by the present invention, the specific installation steps are as follows: [0005] (1) Stand 3 to 4 pairs of gantry towers on both sides of the gantry crane, and place a lifting cylinder on the top of each pair of gantry towers. The lifting cylinder is a core-piercing cylinder, and the steel strand passes through the middle o...
