Description

Technical Field

[0001] This invention relates to the field of construction engineering technology, and in particular to a control method and control device for preventing cranes from tipping over. Background Technology

[0002] The crane trolley, also known as a crane carriage, is the core moving component of bridge, gantry, and tower cranes responsible for lifting operations. It travels laterally along the main beam or boom rails, cooperating with the crane's trolley travel and hoisting mechanism to achieve precise three-dimensional spatial positioning of heavy objects. It mainly consists of a frame structure, a hoisting mechanism, and a trolley travel mechanism. It fundamentally determines the crane's operational flexibility, lifting efficiency, and positioning accuracy, and is key to achieving point-to-point material handling.

[0003] With the rapid development of the national economy, people have increasingly higher requirements for cranes, and cranes are developing in many directions such as large tonnage and ultra-high height. As the tonnage and height of cranes continue to increase, the number of crane overturning accidents caused by improper operation is also increasing. Crane overturning often happens due to a slight tilt, which can cause unpredictable and serious damage. Therefore, in order to reduce the occurrence of such accidents, it is necessary to constantly test the tilt angle of the crane during operation and to learn how to prevent the same accident from happening again.

[0004] However, the traditional way to prevent cranes from tipping over is to add a safety stabilizing rope to the crane and use the crane's four outriggers to stabilize the crane. Although this method is low-cost and intuitive to operate, it is unsafe, highly dependent on manual operation, has strong instability, and cannot accurately obtain the crane's tilt angle.

[0005] To address this, a control method and device for preventing crane tilting is proposed to overcome the shortcomings of traditional methods for detecting crane tilt, which suffer from poor accuracy and reliance on manual readings. Summary of the Invention

A lifting cylinder 2 is fixedly mounted on the outer wall of the circular hole in the middle of the connector 1. A lifting column 3 is movably mounted on the inner wall of the lifting cylinder 2, and a hydraulic cylinder 4 is fixedly mounted on the upper end of the lifting cylinder 2. The lower end of the lifting column 3 adopts a spherical design, and a fixing member 5 is movably mounted on the outer wall of the lifting column 3.

To ensure that the support device and the outer support device have a certain angular offset, and to prevent the outer support device from shifting due to the crane's movement, thus maintaining stability, anti-slip spikes are evenly distributed at the lower end of the spike block 23. These anti-slip spikes are made of polyethylene material, which has a certain degree of elasticity and can effectively absorb and disperse vibrations. At the same time, its surface can be designed with anti-slip textures or structures to increase friction and prevent slippage.
