Embodiment
To make the purpose, technical scheme and advantage of the application clearer, below in conjunction with the application specific embodiment and
Technical scheme is clearly and completely described in corresponding attached drawing.Obviously, described embodiment is only the application one
Section Example, instead of all the embodiments.Based on the embodiment in the application, those of ordinary skill in the art are not doing
Go out all other embodiments obtained under the premise of creative work, shall fall in the protection scope of this application.
Below in conjunction with attached drawing, the technical solution that each embodiment of the application provides is described in detail.
With reference to figure 1, portal frame is included according to the adjustable electric tube expander of exemplary centre-to-centre spacing of one embodiment of the application
1st, mouth expander 2, hydraulic station and electric appliance box 3, slide trucks 4, Spring balancer 5 and tube expansion head 6.
Referring to Fig. 2, center distance adjusting apparatus 61 is included according to the exemplary tube expansion head of one embodiment of the application,
Two groups of suspension linkage members 62 and two groups of tube expansion components 63.
With reference to figure 3, it is (living that swollen first 631, expanding rod is included according to the exemplary tube expansion component 63 of one embodiment of the application
