Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.The present embodiment is implemented premised on technical solution of the present invention, give detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
A kind of converter valve radiator 3 changes frock online, as shown in Figure 1, comprising:
Change assembly, for changing fault radiator 2;
Also comprise:
Dismounting supporting component 1, is inserted into fault radiator 2 both sides and supports the radiator 3 of fault radiator 2 both sides, to change assembly carrying out replacement operation;
Pressure-applying unit 5, is connected with dismounting supporting component 1, and for the power provided support for dismounting supporting component 1, pressure-applying unit 5 is specially force (forcing) pump.
As shown in Figures 2 and 3, dismounting supporting component 1 comprise support, two be respectively used to the elastic support of support two side radiator 3 and the radiator supporting seat 15 for supporting fault radiator 2, two elastic supports are located at support both sides respectively and are all connected with pressure-applying unit 5, and radiator supporting seat 15 is located at frame bottom.
