Further, a base for supporting the branch pipe is arranged below the branch pipe, and the branch pipe is connected with the base through a connecting rod. Avoid the trunk line directly to place subaerial, the trunk line can be followed vibrations when carrying fracturing oil, arranges the trunk line on the base, can avoid the trunk line vibrations to cause and collide wearing and tearing with ground.
Furthermore, an adjusting mechanism is arranged on the connecting rod and used for adjusting the height of the branch pipe in the vertical direction. The ground near the well mouth has fluctuation, and cannot be completely leveled, the height of the branch pipe can be adjusted through the adjusting mechanism, so that the level of the main pipeline is ensured, and on one hand, the circulation resistance of the fracturing oil in the main pipeline can be reduced; on the other hand, the stress between the branch pipes is also reduced, and the service life of the branch pipes is prolonged.
