The top of bar perforating, expanding rod 100 is clamped after expanding rod perforating with the upper surface of expanding rod storing board 71.When needing to hang expanding rod
When, operator directly can hold the expanding rod being hung on the expanding rod storing board 71 of expanding rod storage crossbeam 7 on ground, and by expanding rod
It is hung over after removing on upper layer expanding rod fixed part 1 or lower layer's expanding rod fixed part 2, facilitates and hang expanding rod operation.
As shown in Figure 1, Figure 2 and shown in Fig. 5, in order to guarantee that expanding rod is steadily hung on expanding rod storage crossbeam 7, tube expansion is avoided
Expanding rod is fallen in the machine course of work, and hanging expanding rod structure includes: pressure plate 8, and the side of pressure plate 8 and expanding rod storage crossbeam 7 are hinged；
Driving cylinder 9 is compressed, main part and the expanding rod storage crossbeam 7 for compressing driving cylinder 9 are hinged, compress the cylinder of driving cylinder 9
Bar and pressure plate 8 are hinged, are rotated with stretching prolonged driving pressure plate 8 in compression driving cylinder 9, to pass through the plate face pair of pressure plate 8
The top of expanding rod 100 is compressed.This articulated fixed structure there are it is simple for structure, occupy little space the advantages of, can have
Effect reduces the occupancy in the space to expanding rod storage 7 top of crossbeam, and 8 high stability of pressure plate rotatably compressed, has
Compression effect.
On this basis, as shown in Figures 1 and 5, hanging expanding rod structure includes lifting driver part 10, lifting driver part 10
It is drivingly connected with expanding rod storage crossbeam 7, is gone up and down with driving expanding rod to store crossbeam 7 by lifting driver part 10；Wherein, expanding rod is deposited
Crossbeam 7 is put with first position and the second position, when expanding rod storage crossbeam 7 is in first position, expanding rod storing board 71 with it is upper
Layer expanding rod fixed part 1 is spaced setting, when expanding rod storage crossbeam 7 is in the second position, the lower surface of expanding rod storing board 71 with it is upper
The upper surface contact of layer expanding rod fixed part 1.In this way, after expanding rod is removed from expanding rod storage crossbeam 7, due to expanding rod storing board 71
Lower surface contacted with the upper surface of upper layer expanding rod fixed part 1, expanding rod can successfully pass through upper layer expanding rod fixed part 1 on first
Aperture is not susceptible to the problem of expanding rod deviates, and facilitates and hangs expanding rod operation.
In order to realize the lower surface of expanding rod storing board 71 and effectively contacting for the upper surface of upper layer expanding rod fixed part 1, and keep away
Exempt from excessive and damage equipment pressure between the upper surface of upper layer expanding rod fixed part 1 when expanding rod storing board 71 declines, lifting driving
Component 10 is cylinder, is gone up and down with storing crossbeam 7 by the flexible drive expanding rod of cylinder.Preferably, lifting driver part 10 is two
A, two lifting driver parts 10 are connect with the both ends of expanding rod storage crossbeam 7 respectively.
The present invention also provides a kind of electric tube expander, electric tube expander includes fuselage body and extension expanding rod structure, wherein hangs expanding rod knot
Structure is above-mentioned extension expanding rod structure.
It can be seen from the above description that the above embodiments of the present invention realized the following chievements:
Extension expanding rod structure of the invention, which has, hangs expanding rod state and working condition, and hanging expanding rod structure includes: that upper layer expanding rod is solid
Determine portion 1, upper layer expanding rod fixed part 1 has the first aperture 11 for passing through for expanding rod 100；Lower layer's expanding rod fixed part 2, lower layer is swollen
