In modern industrial production, the tube bundle extractor, as a key equipment, is widely used in the industries such as chemical, petrochemical and electric power. It is mainly used for the tube bundle extraction operation of shell-and-tube heat exchangers, which can effectively improve the efficiency of maintenance and installation work. Among the various components of the tube bundle extractor, the follow-up trolley is a seemingly insignificant but crucial part.

1. Basic overview of the follow-up trolley

• The follow-up trolley is an important part of the tube bundle extractor, usually set on the frame guide rail and closely cooperates with the main traveling crane.
• It is driven by a chain and can move forward and backward along the guide rail, providing auxiliary support and power transmission for the main traveling crane.

1. Structural characteristics

• The structural design of the follow-up trolley is compact and reasonable, usually composed of frame, wheels, driving device and other parts.
• The wheels are made of high-quality materials, with high strength and wear resistance, capable of withstanding large loads and frictional forces.
• A connecting plate is provided on the frame for connection with the hanging plate device of the main traveling crane to ensure the stability and synergy between the two.
• The driving device is responsible for providing power to enable the follow-up trolley to move smoothly along the guide rail.

1. Function and function

• Bearing and support: The follow-up trolley, as a supplement to the main traveling crane, can share part of the load and reduce the burden on the main traveling crane.
• Stability and guidance: Through the synergistic effect of the follow-up trolley, it can ensure the stability of the tube bundle during the extraction process and reduce shaking and deviation.
• Improve work efficiency: The quick movement and accurate positioning of the follow-up trolley help to shorten the time of tube bundle extraction and improve work efficiency.

1. Use and maintenance

• When using the follow-up trolley, it is necessary to regularly check the wear condition of each component and replace the damaged parts in time.
• At the same time, keep the follow-up trolley clean and lubricated to extend its service life.

To sum up, the follow-up trolley plays an indispensable role in the tube bundle extractor. It not only improves the efficiency and safety of the tube bundle extraction work, but also reduces the operation difficulty and labor intensity. Therefore, for the operators of the tube bundle extractor, it is very important to understand and master the use and maintenance methods of the follow-up trolley.
