QTPTower crane is a kind of machinery and equipment widely used in high-rise building construction, which has the characteristics of large carrying capacity, wide range of operation and high efficiency. This paper will analyze the working principle and structure of QTP tower crane in detail.

1. working principle

QTPThe working principle of the tower crane is mainly to drive the reducer and the hydraulic system through the electric motor to make the boom rotate and the lifting hook move up and down to complete the lifting and handling of the goods. Specifically, the working principle of QTP tower crane includes the following links:

Boom rotation: the motor drives the slewing mechanism through the reducer, so that the boom can rotate 360 degrees to realize the lifting and handling of goods in different directions.

The lifting hook moves up and down: the motor drives the hoisting mechanism through the reducer, so that the lifting hook can move up and down to complete the lifting and lowering of the goods.

Leg telescopic: QTP tower crane outrigger is through the hydraulic system control telescopic, telescopic outrigger can ensure the stability and safety of the crane.

2. structure analysis

The structure of QTP tower crane is mainly composed of boom, hoist, slewing mechanism, hydraulic system, electrical control system, outrigger and other components. Specifically, the structure of the QTP tower crane includes the following aspects:

Boom: The boom of QTP tower crane is spliced by multiple steel pipes, which has strong carrying capacity and working range. The boom is usually divided into two types, one is a horizontal arm and the other is a folding arm. Different types of boom are selected according to actual needs.

Hoist: Hoist is one of the core components of QTP tower crane. It is driven by a motor to control the up and down movement of the crane hook to complete the lifting and handling of goods.

Slewing mechanism: The slewing mechanism is another core component of the QTP tower crane. It is driven by a motor to control the rotation of the boom and realize the lifting and handling of goods in different directions.

Hydraulic system: The hydraulic system is one of the important parts of the QTP tower crane. It controls the telescopic legs of the crane and the up and down movement of the lifting hook through hydraulic pumps, oil tanks, oil pipes and other components. The role of the hydraulic system is to convert hydraulic oil into mechanical energy to provide the power and control required by the crane. When using the hydraulic system, you need to pay attention to maintenance and maintenance, regularly replace the hydraulic oil and filter, check the pipeline for oil leakage, and ensure the normal operation of the hydraulic system.

Electrical control system: The electrical control system is the control center of the QTP tower crane. It accurately controls the crane through controllers, buttons and other components. The electrical control system not only controls the operation of the boom, winch, slewing mechanism and other mechanical components, but also monitors the working state of the crane to ensure its safe and reliable operation.

To sum up,QTPThe working principle and structure of the tower crane are very complex, including the synergy of multiple components such as the boom, winch, slewing mechanism, hydraulic system, electrical control system, and outriggers. When using QTP tower cranes, it is necessary to strictly abide by the use specifications and safety standards, pay attention to maintenance and maintenance, ensure the stability and safety of the crane, improve work efficiency and quality, and provide a strong guarantee for the construction of high-rise buildings.
