Design features:
- Compact and reasonable structure:
- The frame is composed of side beams and bottom beams welded together. Hangers are set on both sides of the side beams, and hydraulic pipelines and electrical control lines are installed in the inner cavity of the guide rail. This design makes the equipment structure compact and easy to install and move.
- The bottom beam adopts a hollow structure, one of the bottom beams is used as the hydraulic pipeline led out from the hydraulic oil cavity to connect with the hydraulic cylinder; the other bottom beam inner cavity is equipped with an electrical controller. This layout optimizes the utilization of the internal space and is convenient for maintenance and inspection at the same time.
- Efficient transmission system:
- The transmission system consists of a traction motor, a worm gear reducer, a driving sprocket, and a driving chain. The output shaft of the worm gear reducer drives the sprocket to rotate, and the traction force drives the main traveling vehicle to move back and forth along the guide rail of the frame through the chain to realize the extraction and installation of the tube bundle. This transmission method is stable and reliable, and the transmission efficiency is high.
- Multifunctional operation mode:
- The bundle extractor can adopt two control modes: manual control and remote control. This design facilitates the use of users and improves the flexibility and adaptability of the equipment.
- Precise positioning adjustment:
- A hanging plate device is provided at one end of the main traveling vehicle facing the clamping foot. The hanging plate device is provided with a hanging plate, a lifting hanging plate, and an inclined plate vertically connecting the hanging plate and the lifting hanging plate. These components form a clamping part for clamping the tube sheet of the tube bundle, facilitating the precise positioning and adjustment of the tube bundle.
- Safe and reliable:
- The equipment is equipped with an overload protection function. When the equipment bears a load exceeding its designed load, it will automatically stop running to prevent equipment damage and potential safety accidents.
- Key components such as the top pushing device are made of high-strength materials and have undergone strict testing and verification to ensure that they can maintain good performance and reliability during long-term use.
Innovation points: - New rotary and overturning top pushing device:
- A new rotary and overturning top pushing device completely different from the existing expansion and contraction top pushing structure such as screw or lead screw is adopted. Through the worm gear, 180-degree rotation and overturning can be realized, which can greatly improve the preparation time of the top pushing device in the process of extracting the tube bundle.
- Lifting hanging plate clamping mechanism:
- By clamping the edge of the tube sheet of the tube bundle through the lifting hanging plate, the vertical position of the tube bundle can be quickly adjusted. This design not only improves the working efficiency of position adjustment in the process of extracting and installing the tube bundle, but also enables one bundle extractor to be suitable for more tube bundles of different diameters, greatly expanding its application range.
- Innovative design of the connecting device:
- An adjusting mechanism for the connecting plate that can adjust the load of the tube bundle is set in the connecting device. This design can adjust the angle and height of the connecting plate according to the tube bundle of different diameters, thereby improving the applicability of the bundle extractor.
- Combination of multiple control modes:
- Combining manual control, line control, and wireless remote control in one device, which is a relatively advanced design concept at that time. This design increases the safety and flexibility of the extraction and installation work of the tube bundle.
In summary, the bundle extractor equipment focuses on aspects such as compact structure, efficient transmission, flexible operation, and safety and reliability in design; in innovation, it is reflected in the new rotary and overturning top pushing device, the lifting hanging plate clamping mechanism, the innovative design of the connecting device, and the combination of multiple control modes, etc. These design features and innovation points jointly enhance the performance and usage experience of the bundle extractor.
