Description

Technical Field

[0001] This utility model belongs to the field of engineering machinery control technology improvement, and is particularly applicable to the remote high-precision operation and safety monitoring of tower cranes (tower cranes), specifically involving a tower crane remote control system. Background Technology

[0002] Tower cranes, as commonly used lifting equipment in construction, play a vital role in the building engineering field. However, traditional tower crane operation mainly relies on operators working from the crane's cab on-site, which has many drawbacks.

[0003] First, the on-site operating environment is harsh. The tower crane cab is usually located at a high altitude, and operators face the risks of working at height. In severe weather conditions, such as strong winds, rain, and snow, the operating environment is even more difficult, which can easily have an adverse effect on the physical and mental health of the operators.

[0004] Secondly, the traditional operating method has a limited field of vision. Operators in the cab can only observe the working environment from a limited perspective. For some complex construction scenarios, it is difficult to fully and clearly grasp the surrounding situation, which to some extent increases the difficulty and risk of operation and can easily lead to safety accidents.

[0005] In addition, traditional tower cranes have low control precision and intelligence levels, relying mainly on the experience of operators and manual operation. It is difficult to achieve high-precision control of tower crane positioning, speed adjustment and other operations, which affects construction efficiency and quality.

[0006] Traditional tower crane operation relies on the operator's visual control from the cab, which suffers from large blind spots, high risks associated with working at heights, and low operational precision. While some remote control solutions exist, they generally suffer from high video latency, insufficient positioning accuracy, and limited control functions, failing to meet the demands of complex construction scenarios.

[0007] With the continuous development of technology, remote control technology has been widely applied in various fields. In the field of tower crane control, remote control can effectively solve the problems existing in traditional on-site operation. Through remote control, operators can operate the tower crane from the ground or other safe and comfortable environments, avoiding the risks of working at heights; at the same time, with the help of technologies such as high-definition cameras and high-precision positioning, operators can be provided with a more comprehensive and clearer view and more precise control, improving the safety and efficiency of tower crane operation. Utility Model Content

[0008] The purpose of this utility model is to provide a remote control system for tower cranes, which aims to solve the problems of traditional tower crane operation relying on the driver's visual operation in the cab, resulting in large blind spots, high risks of high-altitude operations, and low operational accuracy.

[0018] The wind speed sensor is installed at the top of the tower crane or the end of the boom to measure the wind speed in the working environment. When the wind speed exceeds the set threshold, the system issues an early warning and restricts the tower crane's movement.

[0019] The wireless weight sensor is installed on the hook assembly of the tower crane to measure the lifting weight of the hook in real time. When the lifting weight exceeds the rated lifting capacity, the system will issue an alarm signal and prohibit the lifting action.

[0020] The slewing encoder is installed on the slewing mechanism of the tower crane and is used to measure the slewing angle of the tower crane, so that the operator can accurately grasp the slewing position of the tower crane.

[0021] The tilt sensor is installed on the tower crane's body or boom to measure the tower crane's tilt angle. When the tilt angle exceeds the set range, the system issues an early warning and takes corresponding protective measures.
