Description

Technical Field

[0001] The invention belongs to the technical field of mechanical installation, and in particular relates to a three-stage Roots vacuum unit installation device. Background Art

[0002] The three-stage Roots vacuum unit is a high-vacuum vacuum equipment, mainly composed of multiple Roots pumps connected in series to improve the ultimate vacuum degree and pumping rate of the vacuum system;

[0003] Before leaving the factory, the three-stage Roots vacuum unit needs to install multiple Roots pumps on the mounting frame. At present, there are two most common ways to install the Roots pumps. One is to carry and install the Roots pumps manually, and the other is to install the Roots pumps by a lifter and manual labor. Since the Roots pumps are heavy, manual transportation is more troublesome and there are greater safety hazards. If the Roots pumps are installed by a lifter and manual labor, although the burden on the workers can be reduced, the lifter can only lift the Roots pumps. When installing the Roots pumps on the mounting frame, manual help is still required to drop the Roots pumps onto the mounting frame. The instability of the lifter's lifting will cause the Roots pumps to fall heavily onto the mounting frame during installation, causing danger. Since the installation of the Roots pumps is not only completed by lifting, but also requires pushing the Roots pumps, the lifter cannot complete the action of pushing the Roots pumps.

[0004] The existing three-stage Roots vacuum unit installation equipment usually relies on manual observation to determine whether the positioning is accurate. The manual observation positioning method requires manual repeated alignment, resulting in inaccurate positioning. Some are also positioned through infrared instruments, but infrared instrument positioning still requires naked eye observation and judgment for alignment. Manual participation will increase the probability of deviation and cause inaccurate positioning.

[0005] In view of the above problems, the present invention designs a three-stage Roots vacuum unit installation device. Summary of the invention

[0049] The workflow of the present invention is:

After that, the supporting mechanism 2, the material discharge clamping mechanism 3, the anti-deflection mechanism 4 and the Roots pump 7 can be moved backward through the cooperation of the front and rear electric guide rails 108 and the front and rear electric sliders 109, until the positioning rotating plate 512 blocks the Roots pump 7. At this time, the assembly hole on the Roots pump 7 The two strips 305 are first moved closer to each other, and the frame plate 306 and the Roots pump 7 clamped inside the frame plate 306 will move vertically upward. Then, the multi-stage electric telescopic rod 204 is started to drive the slide plate 203 to move forward, so that the Roots pump 7 is in a vacant state. Then, the two strips 305 are controlled to move away from each other. At this time, the frame plate 306 and the Roots pump 7 clamped inside the frame plate 306 will move vertically downward slowly until the Roots pump 7 is mounted on the mounting frame 6.
