What are the working principles and characteristics of electric rail turntable?
Electric track turntable is a specialized turning device installed in foundation pits, mainly used to carry transfer vehicles or walking equipment on the track, achieve 90 ° turning (line changing) requirements, especially suitable for circular and cross track scenarios of equipment production lines. The following is an explanation from three aspects: core components, working principles, and performance characteristics:
1, Core components: Key structure of BZP series electric turntable
The BZP series electric track turntable is mainly composed of three core components to ensure stable steering function:
Basic framework: The supporting body that carries the overall structure, is installed in conjunction with the foundation pit, and provides a stable installation foundation for the turntable.
Rotating platform: core working component, pre installed track on the platform surface (matching the specifications of the transfer vehicle track); Internally equipped with patented technology rotary bearings, it can drive the platform to achieve 360 ° clockwise and counterclockwise rotation, balancing flexibility and load-bearing capacity.
Control box: responsible for controlling the operation of the turntable, supporting manual/automatic control modes, integrating variable frequency speed regulation and safety limit function.
2, Working principle: Implementation process of 90 ° steering
The steering logic of the electric track turntable is clear and suitable for the cross track operation requirements of the transfer vehicle. The specific process is as follows:
Transfer vehicle entering the platform: The track transfer vehicle travels along the initial track to the rotating platform of the electric turntable, ensuring precise alignment between the wheels and the platform track.
Turntable start: Select manual or automatic mode through the control box to start the turntable rotation; The turntable relies on the slewing support to drive the platform to rotate until the platform track aligns with the target vertical track.
Complete steering: After the turntable stops, the transfer vehicle exits along the aligned vertical track, achieving a 90 ° steering (line change) to meet the production line requirements of circular or intersecting tracks.
3, Structure and performance characteristics: stable, precise, and safe
Structural design adaptability: The turntable is installed as a whole in a circular foundation pit, with the platform surface flush with the ground to avoid obstructing on-site traffic and reduce the impact of external environment on internal components.
High strength load-bearing performance: The overall structure has sufficient load-bearing strength, stiffness, and resistance to track overload and impact. During rotation, there is no shaking or deviation between the axles, ensuring smooth operation of the transfer vehicle.
Precision and safety guarantee: Automatic deceleration control of the turntable is achieved through variable frequency speed regulation technology, avoiding start stop impact; Key positions are equipped with electronic safety limit devices to ensure precise positioning of the turntable, seamlessly connecting the platform track with the ground track and eliminating the risk of derailment.
Operation flexibility: 360 ° clockwise and counterclockwise rotation is supported, and the response speed is fast. Manual/automatic mode can be switched as required to adapt to the steering requirements of different production rhythms.
