Description

A device for fixing a flexible pipeline for loading and unloading hydrocarbons is intended for pumping hydrocarbons in an aqueous medium, in particular, for technological operations with an ascending flexible pipeline.

It is known that for fixing pipelines, various types of clamps are often used, for example, “Clamp with protrusions” according to patent No. 2560859, which is made in the form of a ring of steel tape with protrusions to ensure connection when the clamp is snug against the product when clamped, however, in the design of the clamp the possibility of its mounting or suspension to other devices or devices is not provided.

In the clamping device, the closest technical solution and adopted as a prototype, according to patent No. 26628 "Reusable clamping device (options)", containing a steel tape covering an elastic hose with a gasket, and made with bent to meet and superimposed ends, through the hole in which the cover plate with the hole is installed, the screw of the tightening fixing mechanism. The device provides adjustment of the clamping force when it is used for rigid fixation of the hose in various mechanisms. However, it is not applicable for work in the marine environment, where fixation of the ascending flexible pipeline is required during loading and unloading of hydrocarbons, as well as in standby operation.

The technical result of the proposed device is to provide reliable fixed retention of the ascending flexible pipe in the form of a hose in an aqueous medium in standby mode without loading and during the process of loading and unloading hydrocarbons.

To achieve the stated result, the device is made in the form of a clamp mounted on a hose through a gasket and consisting of two halves made of steel tape with bent ends that are tightened with bolts-ties. The end of one half of the clamp is made in the form of an eye, and a hole for the rod is made in the opposite ends of both halves. Cheeks are spring-loaded at the ends of the rod, the other ends of which, having an opening, are pulled together by a bolt connection.

A useful model of a device for fixing a flexible pipeline is presented on:

FIG. 1 is a sectional view of a device;

FIG. 2 - section of the device along AA.

The device includes a pipeline 1, gasket 2, half 3 clamps, tie bolts 4, eye 5, ears 6, rod 7, cheeks 8, springs 9, bolt connection 10 and the hole for attaching the cable 11.

Fixation of the flexible pipeline (hose) is as follows: on the flexible pipe 1 through the gasket 2, halves 3 of the clamp are installed, the bent ends of which are fastened with bolts - ties 4. One end of one half of the clamp is made in the form of an eye 5 to ensure operations to capture the hose in non-standard situations, and at the ends of the halves 3 in the form of ears 6, a hole is made for installing the rod 7 with cheeks 8 fixed on its ends, which are spring 9 springs relative to the latter. At the ends of the cheeks 8, tightened by a bolt connection 10, below the connection, a hole 11 for the cable is made, with the help of which the device is technologically fixed in an underwater object, for example, in a buoy installed in an aqueous medium.

The proposed utility model of a device for fixing a flexible pipeline for loading and unloading hydrocarbons ensures that, in standby mode, a technological operation (outside the process of loading and unloading operations) holds the free end of the flexible pipeline on an underwater object, which is carried out by fixing the movable element of the device in the form of cheeks in the hole (clue) object.

The simplicity and reliability of the design of the device provide the possibility of its constant operation in the marine environment, regardless of the state of the water surface, that is, ice cover or unrest.
