Abstract
The utility model provides a built-in integral pressure meter support drum. A large-diameter inner through hole is formed in the middle of a drum body in the axial direction, a plurality of pressure meter containing holes with the axes parallel to the axis of the inner through hole are formed in the drum wall beside the inner through hole with the inner through hole as the circle center, and the inner through hole is in tangency or intersection with the pressure meter containing holes. The split structure of an original bracket containing pressure meters is changed into an integral structure (the pressure meter containing holes formed in the drum wall in the middle section of the drum body) combined with the drum body, limit of the size of the inner through hole of the drum body by the bracket is reduced, and combination of the pressure meters and the drum body is close and firm. The hole diameter of the inner through hole is further expanded, and the inner through hole is convenient to machine. By means of the elastic damping structure, protection of the pressure meters is improved, damage to the pressure meters in the drill pipe placing process, the perforation process and the like can be avoided, and effects of overflowing and over pressure can be achieves by means of the structure of an overflow groove.
