Description

Mortise and tenon type bivalve withholding sleeve structure

Technical Field

The utility model relates to a sleeve structure is withheld to mortise and tenon type bivalve.

Background

In the marine oil and gas exploration industry, PU pipe (pneumatic pressure hose) is often used to wrap hydrophones (e.g., piezoelectric hydrophones, fiber optic hydrophones) and the like in an array to receive ocean bottom seismic signals, and to determine the likely location of ocean bottom oil and gas deposits by analyzing data collected during such seismic surveys to assist in identifying hydrocarbon-bearing geological formations. The arrays are connected in series through metal hard pipe connectors, the PU pipe needs to be connected to the hard pipe connectors at the moment, and in some examples, the PU pipe is tightly connected to the hard pipe connectors among the arrays in a pressing mode through cylindrical buckling and pressing sleeves. The common buckling sleeve connecting process is that the buckling sleeve is sleeved into the joint of the PU pipe and the hard pipe from the shaft end and then is extruded inwards to deform and buckle the surface of the hose at the joint, and the process determines that the inner diameter of the buckling sleeve is only slightly larger than the outer diameter of the hose.

When the Wuhan Puhui ocean photoelectric technology Limited company surveys ocean oil and gas, under abominable sea condition, in order to guarantee the joint strength of whole battle array under abominable sea condition, the PU outside of the pipe still needs the armor steel wire, and the reuse withholds the sleeve and pushes down the armor steel wire and prevents that the steel wire from scattering under abominable sea condition. Because the diameter of the armored steel wire connectors at the two ends of the whole array is larger, the diameter of the whole array is distributed to be thick-thin-thick after being armored, and the buckling sleeve can not be sleeved into the buckling position from the end part of the whole array. At the moment, the buckling and pressing sleeve needs to consider that a split structure is adopted, and the split structure penetrates through the armor steel wires in the radial direction and then is connected into a whole and then is extruded and deformed inwards to press the armor steel wires and the PU pipe, so that the split structure cannot be scattered when being mutually extruded and buckled and pressed in the inward extrusion process. In the previous example, the crimping sleeve proved to be impracticable by means of a two-lobe weld, which, during the inward pressing, broke at the weld and failed to compress the armouring wires.

Disclosure of Invention

The utility model discloses an overcome the problem that above-mentioned technique exists, provide a sleeve structure is withheld to mortise type bivalve. The utility model discloses a withhold sleeve structure has effectively solved current conventionality and has withheld the sleeve and can't radially embolia, withhold the problem on hose, hard tube surface. Because the utility model discloses a withhold the sleeve and be bivalve drum, can follow radial both sides respectively and wrap the pipe fitting, the tenon fourth of the twelve earthly branches structure through withholding the sleeve edge unites two into one and overlaps on the pipe fitting, inwards extrudees to warp again and withholds and connect the pipe fitting.

The utility model adopts the following technical scheme:

the utility model provides a sleeve structure is withheld to mortise and tenon joint formula bivalve comprises two withholding rings, its characterized in that, two withholding rings pass through the concave-convex structure mortise and tenon joint at edge and become a whole ring.

The concave-convex structures at the edges of the two buckling rings are designed into dovetail joints.

The two buckling and pressing rings are thin-wall rings made of rigid materials, and can bear large tensile force without damaging separation after buckling and pressing.

The inner surface of the buckling ring is provided with an anti-skidding groove.

The diameter of the whole ring formed by connecting the two buckling rings is larger than the outer diameter of the hose and smaller than the diameter of the hard pipe connector. The event the utility model discloses a withhold telescopic from radial both sides packing hose, through around radial dislocation removal tenon fourth of the twelve earthly branches connect integratively, withhold the sleeve and can only upwards part and fold up in footpath.

The utility model discloses according to the PU hose length of parcel hydrophone, can adopt a plurality of withholding sleeve cooperations to use, easy dismounting.

The utility model discloses a mortise type bivalve components of a whole that can function independently structure compares and can only embolia from the axle head in other known withholding sleeves, and the components of a whole that can function independently structure can be followed radially and passed hose and hard tube junction, and mortise-tenon joint is together covering its surface, has solved behind the battle armored steel wire whole battle array diameter distribution thick-thin-thick interlude armored steel wire layer can't embolia the withholding sleeve to withhold the problem of withholding. The double-petal mortise-tenon joint sleeve has high strength and is not easy to separate after buckling. And the integral part is processed together, the processing is simple, and the buckling process and the equipment are the same as those of the conventional buckling sleeve.

Detailed Description

The utility model discloses generally speaking withhold the connection field to hose and hard tube. The term "crimp sleeve" refers to an annular member that is compressed against the connection between the hose and the rigid conduit, has an inner diameter that is slightly larger than the outer diameter of the connection between the hose and the rigid conduit, and is compressed against the connection between the hose and the rigid conduit after being deformed by being squeezed inwardly to shrink the diameter, which is known in the industry as crimping.

The present invention will be described in detail with reference to the accompanying drawings.

The mortise and tenon type bivalve withholding sleeve of the utility model has the end surface and the longitudinal section as shown in figure 1 and figure 2 respectively.

The buckling sleeve is a double-section cylinder type and comprises a left buckling ring 1 and a right buckling ring 2, wherein the left buckling ring 1 and the right buckling ring 2 are connected into a whole ring through a concave-convex structure at the edge in a mortise-tenon manner, the left buckling ring 1 and the right buckling ring 2 are machined into a thin-wall circular ring by a rigid material lathe, the utility model discloses a 316L stainless steel is used for manufacturing the buckling ring, and an anti-skidding groove is lathed on the surface of the circular ring, and then two circumferential concave-convex parts with concave-convex edges are cut along longitudinal centering, and the concave-convex shape at the edges is designed into a dovetail tenon, so that the left buckling ring 1 and the right buckling ring 2 can only be separated and folded through radial front-back dislocation movement, and the buckling sleeve radially passes through an armor steel wire layer 3 in the mode, and is integrally sleeved outside the armor.

The telescopic application of withholding is detained to mortise and tenon joint formula bivalve is shown in fig. 3, left side withhold ring 1 and the radial back of assembling of 2 marginal dovetail joint of right withhold ring, withhold on armor steel wire layer 3 surfaces, armor steel wire layer 3 is convoluteed in PU hose 4 outside by many steel wires, PU hose 4 wraps up hydrophone 5, its both sides are connected with hard tube connector 6, PU hose 4 internal seal has filling oil 7, armor steel wire layer both ends are also connected respectively on the hard tube connector 6 of both sides, for compressing tightly connecting armor steel wire 3, the external diameter of both sides hard tube connector 6 is far greater than 3 external diameters of armor steel wire layer, withhold the sleeve and can't embolia from 6 tip of both sides hard tube connector.
