Abstract
The invention discloses a stand pipe limiting device comprising two limiting support frames, wherein the inner side of each limiting support frame is provided with a plurality of limiting idler wheels; the outer side of each limiting support frame is provided with a hydraulic control device which is a hydraulic cylinder; the two limiting support frames are correspondingly installed on a slideway; every limiting support frame is in a semi-ring shape of which one side is provided with a wedge block; one side of the wedge block is provided with a slideway wheel; and the slideway wheel is installed in a sliding chute on the slideway. The stand pipe limiting device has simple and practical structure can be used for limiting the moving space of a stand pipe on the basis of preventing the rigid collision of the stand pipe; and the safe reliability of the installation of underwater facilities is greatly enhanced.
Description
Technical field
The present invention relates to stopping means, relate in particular to and a kind ofly be used for that marine riser reclaims or the standpipe stopping means during lifting.Belong to offshore oil engineering field.
Background technology
Along with the expansion day by day of marine mining scope, the deep-sea oil exploitation has become the important front edge position of petroleum industry.The exploitation of deep water hydrocarbon field is made up of a series of labyrinths, the installation of line equipment is more loaded down with trivial details, especially the installation of PLET (pipeline terminal) and PLEM (pipeline terminal manifold) generally needs by support vessel pipeline to be recovered on the support vessel from the seabed earlier to be fixed, then, pipeline is linked to each other with above-mentioned line equipment, and last integral body is transferred to the seabed.In this process; owing to reasons such as stormy waves stream cause ship motion; and the operation that PLET (pipeline terminal) or PLEM (pipeline terminal manifold) link to each other with standpipe or pipeline; the time that needs is long; for guaranteeing the relatively stable and quality of connection of standpipe position; reduce unexpected the generation, need carry out spacing and protection pipeline.
Traditional S type pipe laying barge, owing to do not possess the spacing function of standpipe, it is very difficult that the said equipment is installed, exist very big potential safety hazard, the situation that standpipe waved or collided hull significantly might occur,, need many auxiliary ship less important works so weather window and constructing operation control are required all very strictness, even need to mobilize some large-scale boats and ships resources, safety and economy are all poor.
Summary of the invention
Main purpose of the present invention is to overcome the above-mentioned shortcoming that prior art exists, and a kind of standpipe stopping means is provided, and it is simple and practical, can limit the activity space of standpipe on the basis that prevents the standpipe rigid collision; Strengthened the security reliability that underwater facility is installed greatly.
The objective of the invention is to realize by following technical scheme:
A kind of standpipe stopping means, it is characterized in that: comprise two spacing support frames, spacing support frame installed inside has several limited rollers, and the outside of spacing support frame is equipped with a hydraulic control device, and two mutual correspondences of spacing support frame are installed on the slideway.
Described spacing support frame is a semicircular, and a Semicircular side is a wedge, and this wedge one side is equipped with the slideway wheel, and slideway is taken turns in the chute that is installed on the slideway.
Described hydraulic control device is a hydraulic cylinder.
Beneficial effect of the present invention: the present invention is simple and practical, can limit the activity space of standpipe on the basis that prevents the standpipe rigid collision; Strengthened the security reliability that underwater facility is installed greatly.

Fig. 1 is the whole perspective view of the present invention.
Fig. 2 is a structure partial perspective view of the present invention.
Major label description in figure:
1. spacing support frame, 2. limited roller, 3. slideway wheel, 4. slideway, 5. hydraulic cylinder, 6. hydraulic pressure locating hole.
The specific embodiment
Shown in Figure 2 as Fig. 1, the present invention includes: two spacing support frames 1, for standpipe defines activity space, and play the effect that prevents standpipe and foul, play a protective role. Spacing support frame 1 is the steel work semicircular, and a Semicircular side is a wedge, and this wedge one side adopts welding connecting mode to be installed to slideway wheel 3; Spacing support frame 1 inboard bolt connecting mode is equipped with 8 limited rollers 2, and it is between spacing support frame 1 and standpipe, and roller 2 is provided with yielding rubber, is used to cushion the bump of standpipe and spacing framework; The outside bolt connecting mode of spacing support frame 1 is equipped with a hydraulic control device, and hydraulic control device is a hydraulic cylinder 5, and the hydraulic cylinder rod of hydraulic cylinder 5 connects as one by bolt and nut pair and spacing support frame 1.The bracing frame of hydraulic cylinder 5 is provided with hydraulic pressure locating hole 6.By the motion of the spacing support frame 1 of hydraulic cylinder 5 controls, and then the motion of control wedge and limited roller 2 and slideway wheel 3, and realized Long-distance Control.Two spacing support frame 1 mutual correspondences are installed on the slideway 4, and in the slideway of spacing support frame 1 wheel 3 chutes that are installed on the slideway 4.
During use, standpipe is returned as the lifting power recovery by winch releasing winch hawser line, and its upper end is fixed on the operating platform, apart from a distance, standpipe upper end the present invention is installed, standpipe is carried out spacing, make its motion only limit to certain space, prevent the collision of itself and ship, then standpipe is carried out operations necessary, operation is finished with rear profile tube and is prepared to transfer, and at this moment, the present invention is opened, discharge standpipe, and the A﹠amp by winch; The R line is transferred standpipe.
Roller, slideway wheel and hydraulic cylinder are the commercially available prod.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment did.
Claims (3)
