DETAILED DESCRIPTION

[0021] The utility model will be specifically introduced below in combination with the drawings and specific examples.

[0022] Tower crane, full name tower crane, is a heavy lifting equipment widely used in construction sites, ports, wharves and other places, used to lift construction materials such as steel bars, bunks, concrete and steel pipes. Tower crane plays a crucial role in construction and is an indispensable tool in modern construction. The main function of tower crane is to vertically transport and horizontally transfer building materials and components. In the construction site, tower crane can efficiently transport building materials, equipment and tools from the ground to the designated floor or location. For example, concrete, steel bars, wood, glass and various mechanical equipment and tools commonly used in construction can be lifted by tower crane. The use of tower crane improves construction efficiency, reduces labor costs and ensures construction safety. The working principle of tower crane is based on the physics principle of lever and pulley system. Its structure mainly consists of metal structure, working mechanism and electrical system. The metal structure includes tower body, tower top, boom, balance arm and other parts, which provides necessary support and stability for the tower crane. The working mechanism is responsible for the movement of the tower crane, including lifting, amplitude changing, rotating and walking. The electrical system is responsible for controlling the operation of the whole tower crane.

[0023] There are many types of tower cranes. According to the rotation method, they can be divided into upper rotation type and lower rotation type. The tower body of the upper rotation type tower crane does not rotate, and the dynamic arm, balance arm and other parts are supported by the rotation mechanism to make full rotation around the center line of the tower body. The rotation support of the lower rotation type tower crane is installed between the base and the rotating platform. Except for the walking mechanism, other working mechanisms are arranged on the rotating platform and rotate together. The use and operation of tower crane need to strictly follow the safety regulations. The operators of tower crane must be professionally trained and obtain the corresponding operation certificate before they can operate. During operation, the operation must be strictly in accordance with the operation procedures to ensure the safe operation of the tower crane. At the same time, the maintenance and maintenance of tower crane are also very important. Regular inspection and maintenance of tower crane should be carried out to timely find and eliminate hidden troubles. In short, tower crane, as an important lifting equipment, plays an irreplaceable role in construction. Its efficiency, safety and stability characteristics provide strong support for modern construction.

[0024] Tower crane turning refers to the horizontal rotation of the upper structure of the tower crane, including the lifting arm, balance arm, cab, and other components, around the center of the tower body. This function enables the tower crane to perform material lifting and installation tasks within a larger range. The realization of tower crane turning mainly relies on its rotating mechanism, which consists of a rotating platform and a driving device. The rotating platform is the rotatable part of the tower crane's upper structure, while the driving device is the power system responsible for driving the rotating platform, typically including an electric motor, a reducer, and a transmission device. The rotation principle is as follows: when the electric motor receives an operation command, it reduces the speed and increases the torque through the reducer, and then transmits power to the rotating platform through the transmission device, driving the entire upper part of the tower crane to rotate. The transmission device generally uses gear transmission or hydraulic transmission. Gear transmission achieves rotation through gear meshing, with the advantages of simple structure and easy maintenance. Hydraulic transmission drives rotation through the pressure of hydraulic oil, with the advantages of smooth transmission and low noise. The rotating mechanism: the rotating motion of the tower crane is achieved through the upper and lower rotating supports, which are installed on the inner and outer rings of the rotating support, respectively, and driven by the small gears of the rotating mechanism. The small gears mesh with the large gear ring of the rotating support, driving the upper rotating support to move relative to the lower rotating support. The large gear ring usually needs to be driven by two to four small gears, which are evenly placed around the large gear ring to ensure the stability and synchronization of rotation. During the tower crane turning process, various safety measures are usually set to ensure safety: limiters: to prevent excessive rotation of the tower crane and avoid structural damage or collisions caused by excessive rotation. Emergency stop button: to quickly stop the rotation of the tower crane in emergency situations to prevent accidents. Balance system: to ensure the stability of the tower crane during rotation and prevent overturning due to center of gravity deviation. Brake system: the rotating brake of the tower crane usually uses brake disc braking, which is achieved through electromagnetic attraction. After the jib stops, the large arm is locked to resist wind load. After power failure, the variable frequency speed regulation tower crane relies on electromagnetic deceleration and braking, with the braking torque varying with speed. The faster the speed, the greater the braking torque. Tower crane turning can efficiently complete various lifting tasks in construction under the premise of safety.

It is suitable for scenarios where multiple tower cranes are working in cross operation.
