Wherein, the bracket 100 is used for being fixedly arranged on a pipeline m connected with a mould n through a flange m1, and the bracket 100 comprises a support rod 110 and at least two plug-in rods 120. At least two insertion rods 120 are vertically connected with the support rod 110, and the insertion rods 120 have first insertion ends 121, and the first insertion ends 121 are used for penetrating through the connecting holes on the flange m1 so that the support rod 110 stands on the pipeline m along the radial direction of the pipeline m.

The lifting assembly 200 comprises a connecting arm 210, an elastic connecting member 220, a sliding plate 230 and a lifting device 240 for connecting the mold n. The connecting arm 210 is connected to the supporting rod 110, the connecting arm 210 is configured to be capable of being supported above the flange m1 by the supporting rod 110 standing on the pipe m, the lifting device 240 is connected to the connecting arm 210 and located on the same side of the supporting rod 110 as the first inserting end 121, the sliding plate 230 is slidably connected to the connecting arm 210 and located between the lifting device 240 and the supporting rod 110, one end of the elastic connecting member 220 is connected to the lifting device 240, and the other end of the elastic connecting member 220 is connected to the sliding plate 230.

In the embodiment of the present disclosure, when the mold n needs to be detached from the pipeline m connected thereto through the flange m1, the two fixing bolts on the flange m1 are firstly detached, the two inserting rods 120 perpendicularly connected to the supporting rod 110 are inserted through the two mounting holes on the flange m1, the first inserting ends 121 of the two inserting rods 120 are inserted into the two mounting holes to support and fix the supporting rod 110, the supporting rod 110 is erected on the outer surface of the pipeline m in the radial direction of the pipeline m, and the connecting arm 210 in the lifting assembly 200 is supported above the flange m 1.

After that, by removing all the fixing bolts on the flange m1 for connecting with the mold n, the elastic force generated by the stretched elastic connecting member 220 is transmitted to the mold n through the plate surface of the sliding plate 230, and the mold n is separated from the flange m1 by the pushing of the sliding plate 230 after losing the bolt fixing with the flange m 1. Finally, a worker only needs to connect the die n separated from the flange m1 with the lifting device 240 to realize the descending and the lifting of the die n, and the die n is disassembled and assembled.
