DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0020] As Figures 1-4 shown, a prefabricated heat-insulating pipe production device includes a base 1 and a turning motor 2. A turning motor 2 is fixedly installed on the surface of one end of the base 1. A turning shaft 3 is fixedly installed at the output end of the turning motor 2. Support plates 4 are fixedly sleeved on the surface of the turning shaft 3 near both ends. A handwheel 5 is arranged behind the support plates 4. An adjusting frame 6 is arranged above the support plates 4. Arc-shaped clamping plates 7 are movably installed on the rear surface of the adjusting frame 6 near the upper and lower parts. A plug 8 is arranged behind the support plates 4.
[0021] Threaded holes 404 are formed in the surface of the support plate 4 near the upper part. An extension plate 401 is fixedly installed on the upper surface of the support plate 4. A moving groove 402 is formed inside the extension plate 401. A threaded knob 403 is movably installed on the front surface of the extension plate 401. The rear end of the threaded knob 403 extends into the moving groove 402. Rotating the threaded knob 403 can cause the adjusting frame 6 to move; a threaded rod 501 is fixedly installed on the rear surface of the handwheel 5. The threaded rod 501 penetrates through the threaded hole 404. A stop cap 502 is threadedly installed at the rear end of the threaded rod 501. A limit ring 503 is fixedly sleeved on the surface of the threaded rod 501 near the rear end. By rotating the stop cap 502, the plug 8 can be conveniently removed from the threaded rod 501 and replaced, so as to adapt to the inner pipes of heat-insulating pipes with different inner diameters; a lifting groove 602 is longitudinally formed in the rear surface of the adjusting frame 6. A rotating rod 601 is movably installed on the upper surface of the adjusting frame 6. The lower end of the rotating rod 601 extends into the lifting groove 602. A threaded sleeve block 603 is fixedly installed on the lower surface of the adjusting frame 6. Threads are provided on the surface of the rotating rod 601 located inside the lifting groove 602 near the upper and lower ends, and the rotation directions of the threads are opposite. When the rotating rod 601 rotates, the two arc-shaped clamping plates 7 can be controlled to approach and separate from each other; a threaded sliding sleeve 701 is fixedly installed on the front surface of the arc-shaped clamping plate 7. The threaded sliding sleeve 701 is sleeved on the surface of the rotating rod 601 inside the lifting groove 602; the threaded sleeve block 603 is sleeved on the surface of the threaded knob 403 inside the moving groove 402. The plug 8 is sleeved on the surface of the threaded rod 501 between the limit ring 503 and the stop cap 502.
[0022] It should be noted that the present utility model is a production device for prefabricated thermal insulation pipes. When in use, an inner pipe is placed inside an outer pipe, and then the outer pipe is placed on the base 1. The flipping motor 2 controls the rotation of the flipping shaft 3, causing the support plate 4 to flip to both ends of the inner pipe. Then, the handwheel 5 is rotated according to the distance between the inner pipe and the support plate 4. As the handwheel 5 rotates continuously, the rear end of the handwheel 5 will continuously approach the inner pipe until the plug 8 sleeved on the rear end of the handwheel 5 is inserted into the inner pipe. Then, the threaded knob 403 of the support plate 4 is rotated, causing the adjusting frame 6 to continuously approach the outer pipe. By rotating the rotating rod 601, the two arc-shaped clamping plates 7 approach each other until the outer pipe is clamped. At this time, the flipping motor 2 controls the flipping shaft 3 to rotate in the reverse direction, causing the support plate 4 to drive the inner pipe and the outer pipe to flip, thus completing the concentric positioning of the outer pipe and the inner pipe, and enabling the foam to be evenly filled between the inner pipe and the outer pipe.
