DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The invention relates to a device for fastening together two devices, wherein
the first device comprises a first frame which carries a body, which has a conical, pointed first end section, and at least one engagement element, which has a first contact section which is arranged to abut against the end section, the engagement element being movable in relation to the end section, considered in the direction of the end section's longitudinal axis, and by means of such a relative movement of the body and the engagement element and under the influence of the end section it can also be moved radially in relation to the end section between a first position, wherein the distance between the longitudinal axis and the engagement element is minimal, and a second position, wherein this distance is at a maximum,
the second device comprises a second frame with an opening with a narrowed section which forms a shoulder section, through which the engagement element can be inserted when it is located in its first position, and which is arranged to engage with a second contact section of the engagement element when the latter has been passed through the opening and is located in its second position.
BACKGROUND OF THE INVENTION
In connection with oil and gas production a device of the above-mentioned type is known in the prior art for devices which have to be connected on the seabed. In this device the body is movable axially in the first frame and the engagement element is mounted radially movably in the frame. For movement of the body a linear hydraulic actuator is employed which is connected to the frame and to a pressure fluid source. The installation of the hydraulic actuator and the coupling thereof to the pressure source are cumbersome, time-consuming and complicated.
In the known device moreover during the connecting process the devices can be forcibly moved some distance towards each other. This distance corresponds to only possible axial extension of inclined planes of the second engagement section. In order that the axial force which is thereby created and the distance should be substantial, however, the engagement element's radial extension must be large. The device is therefore also space-consuming.
Furthermore the engagement element is secured in its second position merely by means of the friction between the end section and the first contact section.
SUMMARY OF THE INVENTION
The object of the invention is to provide a device of the above-mentioned type which is not encumbered by the above-mentioned disadvantages.
The characteristics of the device according to the invention are presented by the following characteristic features.
BRIEF DESCRIPTION OF THE DRAWINGS
The invention will now be described in more detail with reference to the drawing which schematically illustrates a device according to the invention.
FIG. 1 shows a longitudinal section through a first device with components of the device according to the invention, sections of the device being cut away.
FIG. 2 shows a longitudinal section through a second device with sections according to the invention, sections of the device being cut away.
FIG. 3 shows a longitudinal section through the devices which are illustrated in FIGS. 1 and 2, where the devices are placed together and partially connected to each other, and sections of the devices are cut away.
FIG. 4 shows a longitudinal section which resembles that which is illustrated in FIG. 3, but where the devices are fully connected.
FIG. 5 shows a section along line V--V through the devices which are illustrated in FIG. 4, on an enlarged scale, where three engagement devices are held in a radially outer position.
FIG. 6 is a side view of one of the engagement devices which are illustrated in FIG. 5.
FIG. 7 shows a section which resembles the section according to FIG. 1, but where a different embodiment of a central screw is illustrated.
