Coupling for a cement head |
摘要 |
Disclosed is an improved coupling for cement heads. One exemplary cement head includes a first module comprising a first end, a first outer surface, and a plurality of first protrusions extending radially outward from the first outer surface, each of the plurality of first protrusions comprising a first profile in which (i) a first engagement surface faces axially away from the first end and (ii) a first support surface forms a first oblique angle relative to an axis; and a bridge configured to engage the plurality of first protrusions. |

1. A cement head, comprising:
a first module comprising a first end, a first outer surface, and a plurality of first protrusions extending radially outward from the first outer surface, each of the plurality of first protrusions comprising a first profile in which (i) a first engagement surface faces axially away from the first end and (ii) a first support surface forms a first oblique angle relative to an axis; a first supplemental protrusion having a rectangular profile and extending radially outward from the first outer surface at a location between the first end and the plurality of first protrusions; a second module comprising a second end axially adjacent the first end of the first module, a second outer surface, and a plurality of second protrusions extending radially outward from the second outer surface; and a second supplemental protrusion having a rectangular profile and extending radially outward from the second outer surface at a location between the second end and the plurality of second protrusions; and a bridge configured to engage the plurality of first protrusions, the first supplemental protrusion, the plurality of second protrusions, and the second supplemental protrusion, wherein the plurality of first protrusions comprises a first protrusion and a second protrusion disposed between the first protrusion and the plurality of second protrusions and having a maximum axial width greater than a maximum axial width of the first protrusion, and wherein the second plurality of protrusions comprises a third protrusion and a fourth protrusion disposed between the third protrusion and the first plurality of protrusions and having a maximum axial width greater than a maximum axial width of the third protrusion. |
