Can 360 degree rotation it is hinged on the operational platform, middle part by support slidably support on the operational platform, the other end fixes
Frame is held out against, the hinge joint of telescopic rod is located on furnace shell central axis, holds out against the hydraulic top that frame is equipped with multiple linkages, holds out against on frame
Hydraulic top and hanger on cooling wall correspond.
Further, support is at least two groups A-frame, and the top of A-frame is connect with telescopic rod, two supporting legs of A-frame
Bottom end be equipped with pulley.
Further, the inner bearing casing and outer bearing casing by bearing fit are equipped at the hinge joint of telescopic rod, it is interior
Bearing sleeve upper end is connect with telescopic rod, lower end is equipped with and sells for the line position of Anti-extrusion, and outer bearing casing is fixed with operating platform.
A kind of last furnace shell cooling wall installation method based on above-mentioned last furnace shell cooling wall installation system is first flat by operation
Platform be fixed in furnace shell and guarantee with furnace shell central axis, then assemble adjustable holding device, when assembling, first cut with scissors telescopic rod
It connects on the operational platform, then the erection support on telescopic rod, then installation holds out against frame and hydraulic top on telescopic rod, after assembling, first
It is lifted near muti-piece cooling wall to hole to be installed simultaneously by hanger, then adjusts the rotation angle and collapsing length of telescopic rod
So that hydraulic top corresponds and hold out against cooling wall, all cooling walls are headed into corresponding hole finally by hydraulic top.
The beneficial effects of the present invention are:
The system is headed into cooling wall in hole by hydraulic top, by adjusting the rotation angle and collapsing length of telescopic rod
So as to adjust the setting angle of cooling wall and hole, therefore installation accuracy is high；The system can install multiple cooling walls simultaneously and lead to
It crosses hydraulic top and applies pressure, installation effectiveness is high, reduces construction cost.

Specific embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples.
As shown in Figure 1 to Figure 3, a kind of last furnace shell cooling wall installation system, including adjustable holding device, be located at furnace shell 1
It is interior and can lift with the operating platform 8 of 1 central axis of furnace shell and simultaneously the hanger 2 of muti-piece cooling wall 3, adjustable holding device packet
Include telescopic rod 6,6 one end of telescopic rod being hinged on operating platform 8 of 360 degree rotation, middle part is slidably supported by support 9
On operating platform 8, the other end be fixed with and hold out against frame 5, the hinge joint 7 of telescopic rod 6 is located on 1 central axis of furnace shell, holds out against on frame 5
Hydraulic top 4 equipped with multiple linkages, the cooling wall 3 held out against on hydraulic top 4 and hanger 2 on frame 5 correspond.When work: first
Operating platform 8 is fixed in furnace shell 1 and guarantee with 1 central axis of furnace shell, then assemble adjustable holding device, when assembling,
First telescopic rod 6 is hinged on operating platform 8, then the erection support 9 on telescopic rod 6, then installation holds out against frame 5 on telescopic rod 6
And hydraulic top 4, after assembling, first passes through hanger 2 while lifting near muti-piece cooling wall 3 to hole to be installed, then adjust flexible
The rotation angle and collapsing length of bar 6 correspond hydraulic top 4 and hold out against cooling wall 3, will own finally by hydraulic top 4
Cooling wall 3 heads into corresponding hole.The system is headed into cooling wall 3 in hole by hydraulic top 4, by adjusting telescopic rod 6
Rotation angle and collapsing length so as to adjust the setting angle of cooling wall 3 and hole, therefore installation accuracy is high；The system can be same
When multiple cooling walls 3 are installed and pressure is applied by hydraulic top 4, installation effectiveness is high, reduces construction cost.
As shown in Figure 1 to Figure 3, in the present embodiment, support 9 is at least two groups A-frame, the top of A-frame and flexible
