People's Network? Tianjin Window October 3rd: After the National Day ceremony, the reporter called Sun Yuehai, the person in charge of the engineering technical support of Tianjin float engineering and the professor of Mechanical Engineering of Tianjin University. Sun Yuehai and his leading engineering and technical support team at Tianjin University have overcome one technical difficulty after another in the manufacturing stage of floats.
This time, Tianjin University organized more than 10 experts from mechanical engineering colleges, automation colleges, architectural design institutes, materials colleges and other units to participate in solving technical problems such as float load, hoisting, electrical control, mechanical transmission, vibration stability, etc. The float is perfect.
The biggest highlight of the "Binhai New Look" float is the LED display on the rotating table. The high-definition, large-area LED display greatly enhances the expressive performance of the float, but this large screen also brings the float to the float. The biggest technical challenge. Because the floats are transported and transferred, the requirements must be reduced to 4.15 meters in order to pass safely, so the LED screen cannot be made into a whole. When two LEDs are spliced, a gap will occur, which will affect the playback effect of the LED screen. Sun Yuehai organized experts, several consecutive day and night demonstration solutions, and finally controlled the gap between the two screens to within 0.3 mm, and even one piece of paper could not be inserted.
In addition, there are two trains on the floats running around the Beijing-Tianjin intercity train, which is not easy to implement. Because if two intercity trains are running at different speeds, they will collide. In order to solve this problem, Tianda mechanical experts designed the mutual sensing device of the front and rear of the vehicle to achieve a consistent speed.
With Push-in connection technology, you can connect conductors easily – both directly and without tools, insert forces reduced by 50%. it is suitable for various applications. Insert rigid conductors or conductors with ferrules from 0.25mm² into the conductor shaft.The contact spring opens automatically and provides the required pressure force against the current bar.
When installing smaller conductors from 0.14mm², use a standard screwdriver to push the orange button and actuate the contact spring.
Push-in Connection have test and passed various certificates. For example, Vibration resistance in accordance with railway standard DINEN50155,shock and corrosion resistance in accordance with current shipbuilding registers.
