[0029] Example 1
[0030] Take the continuous casting turntable which weighs 224 tons and the bearing is directly replaced with 4325mm bearing as an example, as follows:
[0031] Such as Figure 1~3 As shown, a saddle arm lifting device for replacing the slewing bearing of a continuous casting turntable includes a saddle arm support device 1, a hydraulic lifting device 2, and a bearing laterally moving bracket 3.
[0032] The saddle arm support device 1 includes a steel structure load-bearing support 4 under the saddle arm 6 of the turntable and an internal rigid reinforcement member 5 of the turntable. The steel structure load-bearing support 4 is superimposed directly under the saddle arm 6 in a 400H steel well shape, In addition, there is a gap between the steel structure load-bearing support 4 and the saddle arm 6 to place the hydraulic jack 11. The internal rigid reinforcement 5 of the turntable is made of 4 seamless steel pipes of D273*12, welded to the top beam of the saddle ...
