Pipe joint assembly and transportation equipment

The invention relates to the technical field of transportation equipment, in particular to a pipe joint assembly and a set of transportation equipment. The pipe joint assembly comprises a pipe joint with a through hole, an inner press piece, an outer press piece and a fastener, wherein the inner press piece, the outer press piece and the fastener are arranged on the pipe joint in a sleeved mode. A trapezoidal face is arranged on the outer side face of the pipe joint, and one end of the pipe joint penetrates through an opening of a pipeline wall. The inner press piece is located between the trapezoidal face and the inner wall of the pipeline wall. The outer press piece is located on the outer side of the pipeline wall. The fastener is connected with the pipe joint through threads, and the inner press piece and the outer press piece are made to clamp the pipeline wall. According to the pipe joint assembly, by screwing down the fastener, the inner press piece and the outer press piece located on the two sides of the pipeline wall respectively can be made to clamp the pipeline wall, a set of special equipment can be further connected with the pipe joint of the pipe joint assembly, and therefore, the process of installing the special equipment on a pipeline can be simplified through the pipe joint assembly, the application range of the pipe joint assembly can be wider, and the installing reliability is improved.
