Embodiment

[0071] refer to Figure 5 , a construction site has 1 tower crane, a steel bar stockyard P1 and a steel structure stockyard P2. It needs to go back and forth between the two stock yards and the working surface. The tower crane is controlled by the method of the present invention, the tower crane intelligent monitoring system 1 is installed on the tower crane, and the two remote controllers of the tower crane are respectively located in the material yard and the construction work surface.

[0072] Assuming that the tower crane needs to transport the steel bars from the steel bar stockyard P1 to the construction work surface C, at this time, the loading remote control 2 is located at the steel bar stockyard P1, and the unloading remote control 3 is located at the construction work surface C, and the following operations are started,

[0073] Step 1. After the system initialization is completed, the tower crane is in the automatic tracking mode, and the two remote controllers of...

Abstract

The invention discloses a remote control and automatic tracking combined intelligent safety control method for a tower crane. The remote control and automatic tracking combined intelligent safety control method comprises the following steps: step 1, initialization is started; step 2, the tower crane automatically tracks a feeding remote controller; step 3, the feeding remote controller is activated, and lifting hook positioning and feeding operation are completed; step 4, if the feeding remote controller fails, the tower crane automatically tracks a discharging remote controller; step 5, the discharging remote controller is activated, and lifting hook positioning and discharging operation are completed; and step 6, if the discharging remote controller fails, the tower crane automatically tracks the feeding remote controller again. The steps 2-6 are repeated, and the next hoisting operation of the tower crane is completed circularly. According to the method, on the premise of guaranteeing hoisting safety, the safety risk of overhead working of a tower crane driver is avoided, the method is suitable for the working condition characteristic of random hoisting on a construction site, the requirement for accurate positioning is met, and the labor cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of tower crane intelligent control, and relates to a tower crane intelligent safety control method combining remote control and automatic tracking. Background technique [0002] Tower cranes (tower cranes for short) are the main hoisting tools for building houses and bridges. Due to high-altitude operations, according to relevant standards, tower crane drivers must obey ground instructions. During this process, tower crane drivers need to be highly concentrated, labor-intensive, and prone to fatigue, which is a major hidden danger of tower crane accidents. In order to solve the labor risk problem of tower crane drivers working at heights, people have been working hard to study unmanned tower cranes. As early as the 1990s, there was a tower crane remote control method. The driver does not need to go up the tower, and uses the remote control wireless signal to control the tower crane. The advantage of this me...
