Between top plate 912 and the other end of bottom plate 911.Tension 94 selects adjustable reverse drawing spring, the adjustable reverse drawing bullet
Spring includes the connecting rod 941 for being fixed on 912 bottom of top plate, the reverse drawing spring 942 being set in connecting rod 941, is set in instead
Draw the upper bush 943 and lower sleeve 944 outside spring 942, wherein the top phase screw thread of the lower part of upper bush 943 and lower sleeve 944
Connection, the lower part of lower sleeve 944 are fixed on bottom plate 911, the upper end of reverse drawing spring 942 and the platform for being set to 943 inner wall of upper bush
Rank 9431 offsets, the lower end of reverse drawing spring 942 and the flange of 941 lower part of connecting rod offset and under so that connecting rod 941 is had always
The trend of shifting.When need to increase pinch roller 92 exchange the pressing force of heat pipe H when, it is only necessary to by upper bush 943 be rotated down it is certain away from
From the step 9431 on 943 inner wall of upper bush also moves down therewith, keeps the reverse drawing spring 942 to offset with step 9431 further
Compression, and then increase the power that connecting rod 941 moves down so that the pressure that pinch roller 92 acts on heat exchanger tube H increases；It is pressed when needing to reduce
When the pressing force of 92 exchange heat pipe H of wheel, it is only necessary to upper bush 943 be rotated up a certain distance so that reverse drawing spring 942 is slightly
It unclamps, reduces the active force to connecting rod 941, and then reduction pinch roller 92 and locating wheel 93 act on the pressure on heat exchanger tube H.
When around pipe, as shown in figure 3, by operating platform 31 and wait for that coiling core 7 is moved to by pipe vehicle, it will be on pipe vehicle
Pivoted arm 51 is adjusted to required height and angle, and adjusts telescopic arm 52, makes pressing positioner 9 and core on telescopic arm 52
The distance between 7 meet around pipe requirement, and the heat exchanger tube H on each pipe winding disk 10 is then passed through pressing positioner 9, concrete operations
Step is：Tension 94 is first unclamped, telescopic support 95 is made to support top plate 912 and the pinch roller being connected with top plate 92,
Heat exchanger tube H is placed into the positioning groove 932 of locating wheel 93 further according to coiling screw pitch, then receives again telescopic support 95
Pinch roller 92 is placed into 93 top of locating wheel and compresses heat exchanger tube, according to required pressing force, adjusts tension 94 by contracting
It can carry out the coiling of heat exchanger tube.
With the progress around pipe, under the control of control system 6, electric bicycle 2 is according to the speed around pipe in upper lower railway
200, it walks along the axial direction of core 7 on 100, with becoming larger for 7 diameter of core, passes through control system 6 and control third electricity
Machine 321 and the operating of the second motor 551 so that the height of the pressing positioner 9 on telescopic arm 52 increases and still kept with core 7
It is certain around pipe distance, to ensure around tube efficiency and quality.And during around pipe, operating personnel can be controlled by control system 6
Driving motor 431 processed operates, and the first feed screw nut pair 432 being connected with driving motor 431 drives chain-wales 41 to after-contraction, side
Convenient to operate personnel do not interfere with the progress around pipe also while walking between operating platform 8 and hoistable platform 31.
