Specific embodiment
Below by specific embodiment, the technical solution of the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of Shaft drawer workbench pulls out axis jack including support frame and coaxial arrangement
4, annular fixed disk 5 and articulated shaft connector 6, the axis jack 4 that pulls out are mounted on support frame as described above, the annular fixed disk
5 are connect by multiple connection pawls 7 with the outer shell for pulling out axis jack 4, the articulated shaft connector 6 be mounted on described in pull out axis thousand
8 end of piston rod on jin top 4, the annular fixed disk 5 are arranged on the travel path of the articulated shaft connector 6；Articulated shaft
Connector 6 is for connecting articulated shaft 9 to be dismantled, and annular fixed disk 5 is for being against with hydraulic support frames, when pulling out axis jack
When 4 pulling articulated shaft 9, the annular fixed disk 5 applies an outside thrust to hydraulic support, guarantees the stabilization of drawing process
Property.
Support frame as described above specifically includes bracket 3, two lifting jacks 2 at the 3 bottom both ends of bracket is arranged in and connect
The pedestal 1 in each 2 bottom end of lifting jack is connect, is provided with installation groove 31 on the bracket 3, it is described to pull out axis jack
4 are mounted in the installation groove 31；By adjusting the height of two lifting jacks 2, the adjustable height for pulling out axis jack 4
Degree and tilt angle, are aligned the central axis for pulling out axis jack 4 and the central axis of articulated shaft 9, guarantee the smooth of pulling force.
