The invention relates to a stretching device which is used for providing tensioning force for a sealing clamp, the sealing clamp comprises a first clamp and a second clamp arranged oppositely, the sealing clamp further comprises a plurality of fasteners, and each fastener penetrates through a first connecting hole and is connected with a corresponding second connecting hole so as to fasten the first clamp and the second clamp. The stretching device comprises a stretching driving assembly and a stretching piece, the stretching driving assembly can be supported on the first clamp, one end of the stretching piece is detachably connected with the stretching driving assembly, the other end of the stretching piece can penetrate through the first connecting hole to be connected with the second connecting hole, and the stretching driving assembly is used for driving the stretching piece to move. A tensile force is generated to move the second jig toward the first jig. According to the stretching device, the sealing clamp can be stretched remotely easily, so that the sealing filler in the second clamp deforms and is tightly attached to the sealing weld joint, and the weld joint of the to-be-sealed part is sealed.

    本发明涉及一种拉伸装置,用于向密封夹具提供拉紧力,密封夹具包括第一夹具和相对设置的第二夹具,密封夹具还包括多个紧固件,每一个紧固件穿设一个第一连接孔并与相对应的一个第二连接孔相连,以紧固第一夹具与第二夹具,拉伸装置包括拉伸驱动组件和拉伸件,拉伸驱动组件能够支撑于第一夹具,拉伸件一端可拆卸地与拉伸驱动组件相连,另一端能够穿设第一连接孔与第二连接孔相连,拉伸驱动组件用于驱动拉伸件运动,以产生使第二夹具朝向第一夹具移动的拉伸力。本申请提供的拉伸装置,易于对密封夹具进行远程拉伸,使第二夹具内部的密封填料发生形变并与密封焊缝贴合紧实,从而实现对待密封件的焊缝的密封。
