Abstract

The utility model provides a detachable square tube box pressing device, which adopts an inner and outer double-module mechanical sealing structure and comprises an inner force bearing module, an outer force bearing module, an outer force bearing module, an inner force bearing module, an outer force bearing module, an inner force bearing module and an outer force bearing module, and is characterized in that the inner force bearing module is an adjustable I-shaped steel cross arm provided with a telescopic mechanism used for adapting to square tube boxes with different widths; the dynamic sealing module comprises a sealing plate, a pull rod group and a quick-release flange assembly; the sealing plate and the flange cover are provided with pressure test interfaces which are used for connecting a pressure source and pressure detection equipment. The hydraulic telescopic arm has the advantages that the hydraulic telescopic arm structure of the adjustable I-shaped steel cross arm can quickly adapt to square tube boxes of different width specifications, and the traditional blind plate welding procedure is thoroughly eliminated; through the pull rod group and the quick-release flange assembly of the dynamic sealing module, the test device can be quickly mounted and dismounted.
