Analysis report on the working principle of the torque limiter of the truck crane
I. Background and purpose of the reportWith the rapid development of industrialization and urbanization, truck cranes, as an important mobile lifting equipment, play a vital role in construction, logistics and transportation, port loading and unloading and other fields. However, there is a risk of overloading during the operation of truck cranes, which may lead to serious consequences such as equipment damage and operation safety accidents. Therefore, the configuration of torque limiters has become the key to ensure the safe operation of truck cranes. This report aims to analyze the working principle of the torque limiter of truck cranes in detail and provide technical reference and safety guidance for the industry.
II. The importance of torque limiters
The torque limiter is a safety protection device installed on the truck crane, which is used to monitor the lifting torque of the crane in real time, and issue an alarm or automatically stop the operation when the preset safety limit is reached to prevent accidents caused by overloading. The use of this equipment has greatly improved the safety of operations and reduced the incidence of mechanical failures and safety accidents caused by improper operation.
III. Working principle of torque limiter
The working principle of torque limiter is based on the theory of torque balance in mechanics. By detecting the lifting weight and boom length of the crane, the actual operating torque is calculated and compared with the preset safety torque. Its core components include sensors, signal processing units, display monitoring interfaces and control actuators.
Sensor part: usually using tension and pressure sensors, angle sensors, etc., responsible for real-time collection of data such as crane hook load and boom angle.
Signal processing unit: convert the physical quantity collected by the sensor into electrical signals, and perform amplification, filtering and other processing to obtain accurate measurement values.
Display monitoring interface: convert the processed signal into digital or graphic information, so that the operator can intuitively understand the current operation status.
Control actuator: when the detected torque approaches or exceeds the set value, the control actuator will issue an audible and visual alarm, and even automatically adjust the crane action or cut off the power source to avoid accidents.
IV. Technical characteristics and development trends
The torque limiter of modern truck crane has the characteristics of high precision and high reliability, and can adapt to complex and changing operating environments. At the same time, the development of intelligence and networking enables the torque limiter to be connected to the remote monitoring system to achieve remote transmission and centralized management of data. In the future, with the application of Internet of Things technology and artificial intelligence, the torque limiter will be more intelligent, capable of self-diagnosis and predictive maintenance, and further improve the safety and efficiency of operations.
V. Conclusion
The working principle of the torque limiter of the truck crane reflects the advanced nature of modern engineering machinery safety technology. Through real-time monitoring and intelligent control of the crane's operating status, the torque limiter effectively prevents the risks brought by overloading operations and ensures the safety of the operation process. In the future, with the continuous advancement of technology, the torque limiter will play a greater role in improving the safety of truck crane operations and promoting the healthy development of the industry.
