Description

Variable-angle bracket for laying socket type submarine glass fiber reinforced plastic pipeline

Technical Field

The invention relates to a submarine glass fiber reinforced plastic pipeline laying device, in particular to a variable-angle bracket capable of preventing a glass fiber reinforced plastic pipeline from being suspended.

Background

The current socket joint formula submarine glass steel pipe way adopts the stinger to lay the in-process, causes the stinger angle of intaking to change because of reasons such as the depth of water change to make to form certain angle between stinger and the launching cradle, lead to the stinger terminal to the launching cradle front end between regional treat that the pipeline of laying is easily unsettled, thereby cause pipeline or socket joint to damage.

In view of the above, there is a need for a device for lifting a pipeline between a stinger and a launcher, and capable of changing its height and angle along with the change of the angle of the launcher to attach the pipeline to be laid, thereby preventing the pipeline from being damaged due to suspension in the laying process.

Disclosure of Invention

The invention provides a variable-angle bracket for laying a socket type submarine glass fiber reinforced plastic pipeline, which mainly plays a role in lifting a suspended section of pipeline between a launching frame and a pipe bracket when laying the socket type submarine glass fiber reinforced plastic pipeline, and prevents the pipeline from being damaged due to suspension at the position.

In order to achieve the purpose, the technical scheme adopted by the invention for solving the technical problems is as follows: the utility model provides a variable angle bracket for socket joint formula submarine glass steel pipeline lays, by slide rail, front beam, rear beam, anterior fixed hydraulic jack and rear portion movable hydraulic jack are constituteed, two on front beam and the rear beam are arranged in to the slide rail, the front beam is connected with anterior fixed hydraulic jack through the pivot, the rear beam is connected with rear portion movable hydraulic jack through the pivot, the direct fixed connection of anterior fixed hydraulic jack is on the construction deck, rear portion movable hydraulic jack is through pivot and rear portion base fixed connection on the construction deck.

Further, the slide rail is used for bearing the glass fiber reinforced plastic pipeline to be laid, and the height and the angle of the slide rail are controlled by utilizing the front fixed hydraulic jack and the rear movable hydraulic jack, so that the glass fiber reinforced plastic pipeline is attached and the bearing capacity is practically provided.

Further, when the device is used, the submarine fiber reinforced plastic pipeline to be laid slides to the position above the variable-angle bracket, and the angle and the height of the slide rail are adjusted by jacking or contracting the front fixed hydraulic jack and the rear movable hydraulic jack, so that the slide rail supports the fiber reinforced plastic pipeline at the position.

Further, when the water depth is increased, the angle of the variable-angle bracket is changed along with the water depth, and when the glass fiber reinforced plastic pipeline is raised, the sliding rails are lifted by adjusting the heights of the front fixed hydraulic jack and the rear movable hydraulic jack so as to support the glass fiber reinforced plastic pipeline, so that the glass fiber reinforced plastic pipeline is prevented from being suspended.

Further, when the water depth is reduced, the height of the slide rail of the variable-angle bracket is reduced, and the angle of the slide rail of the bracket is adjusted to adapt to the gentle launching angle of the glass fiber reinforced plastic pipeline.

The invention has the beneficial effects that:

the invention can adjust the height and angle of the self slide rail along with the change of the height and angle of the pipeline when the socket type submarine glass fiber reinforced plastic pipeline is laid, and provides the pipeline with support, thereby preventing the suspension condition after the submarine pipeline between the launching rack and the stinger is raised due to the change of the angle of the stinger and preventing the pipeline self or the socket joint from being damaged.

Detailed Description

The invention is further illustrated with reference to the following figures and examples.

As shown in fig. 1 to 3, the variable angle bracket 14 for laying a socket type submarine glass fiber reinforced plastic pipeline of the present invention is composed of a slide rail 1, a front beam 2, a rear beam 3, a front fixed hydraulic jack 4, a rear movable hydraulic jack 5, and a rear hydraulic jack base 6. The sliding rail 1 is divided into a left sliding rail 7 and a right sliding rail 8, the two sliding rails 1 are arranged on the front cross beam 2 and the rear cross beam 3, the front cross beam 2, the rear cross beam 3 and the jack part are respectively provided with a connecting end 9, one connecting end is a concave connecting groove, the other connecting end is a convex connecting groove, bolt holes are formed in the concave connecting groove and the convex connecting groove, and the concave connecting groove and the convex connecting groove are matched and correspond to the bolt holes in position; the bottom of the rear movable hydraulic jack 5 is also provided with a connecting end and is connected with a jack base 6, the jack base 6 is directly welded with a ship deck 10, and the front fixed hydraulic jack 4 is directly fixed on the ship deck 10.

As shown in fig. 4(a), (b), and (c), the variable angle bracket 14 of the present invention adjusts the height and angle of the slide rail 1 by raising or lowering the front fixed hydraulic jack 4 and the rear movable hydraulic jack 5, thereby adapting to the position of the glass fiber reinforced plastic pipe 11.

When the invention is used, as shown in fig. 5, the jacking of the front and rear groups of hydraulic jacks is adjusted according to the height and angle of the glass fiber reinforced plastic pipeline 11 suspended above the variable-angle bracket 14, so that the slide rails 1 arranged on the cross beam are parallel to the suspended glass fiber reinforced plastic pipeline 11 until the glass fiber reinforced plastic pipeline 11 is finally attached and provides bearing.

When the water depth changes in the construction process, as shown in fig. 6 and 7, the angle between the stinger 12 and the launcher 13 changes, and the glass fiber reinforced plastic pipeline 11 is suspended again, the lifting heights of the two sets of jacks are adjusted according to the pipeline position, so that the suspended glass fiber reinforced plastic pipeline 11 is supported by the slide rail 1 again.
