Description

The invention relates to shipbuilding, in particular, to devices for monitoring displacements of a drilling vessel.

A device for monitoring displacements of a drilling vessel is known, comprising a carriage with an inclinometric sensor mounted on it by means of a hinge suspension, mounted with the possibility of vertical movement along guides in the shaft and connected kinematically with the mechanism of its vertical movement, counterweight mounted with the possibility of vertical motion in the platform along additional guides, a counterweight position sensor, as well as a common cable attached at one end to the bore, interacting with the inclin The gauge sensor is stored in guide blocks mounted on the carriage and counterweight, and placed on the other end of the winch 1. A disadvantage of the known device is that the measured parameters of the displacements of the drill vessel are small.

The aim of the invention is to increase the reliability of the measured parameters of the hull vessel hull offsets.

The goal is achieved by the fact that a device for monitoring displacements of a drilling vessel, containing a carriage mounted on it by means of a hinged suspension with an inclinometric sensor, mounted with the possibility of vertical displacement along the guides in the shaft and connected kinematically with the mechanism of its vertical displacement, the counterweight mounted with the possibility of vertical movement in the alignment along additional guides, a counterweight position sensor, as well as a common cable attached at one end to the core u, interacting with an inclinometer sensor, stored in guide blocks mounted on a carriage and counterweight, and wound at the other end on a winch, is equipped with transit drums, an additional guide block and a flexible link that is passed through the aforementioned additional guide block and transit the drums and their ends are attached to the counterweight, forming a closed branch, with one of the retracting drums kinematically connected with the counterweight position sensor.

FIG. 1 shows schematically a device for monitoring the displacement of drilling vessels in the working position, general view; in fig. 2 is a view A of FIG. one.

The device for monitoring the displacements of the hull 1 of the drilling vessel comprises a carriage 2 with an inclinometric sensor 4 mounted on it by means of a hinged suspension 3, mounted with the possibility of vertical movement along the guides 5 in the shaft 6 made in the housing 1

The device also includes a counterweight 8, Restored with the possibility of a vertical oro chain and an additional 9 of the vessel, but with a guide rail 10,

The device is equipped with transit drums 18, an additional guide block 19 and a flexible link 20- (channel), transit drums 18 are mounted in the lower part of the additional clamp 9, in which the counterweight 8 is placed, the additional guide block 19 is mounted in the upper part of the additional plates 5, and the flexible link 20 is passed through the additional guide block 19 and the transit drums 18 and is attached with its ends to the counterweight, forming a closed branch. One of the transit drum 18 is kinematically connected to the sensor 11.

canopy counterweight.

The device works as follows.

After placing the bark 13 on the underwater ground, the KapCTKi lifting and lowering mechanism 7 is turned on: i the carriage 2 is lowered into the lower part of the drilling vessel 6 of the drilling vessel, where it is fixed motionless.

In the process of lowering the core 13, the counterweight 8, the mass of which is less than the mass of the core 3, occupies the extreme upper position, after u have one hundred ak; The crust 13 on the underwater ground is etched part of the common rope 12, sufficient to lower the counterweight 8 to approximately the middle position, against which the counterweight 8 moves up and down, compensating for the vertical motion of the vessel and maintaining constant tension in the common cable 12.

At the same time, a flexible (rope) 20, reserve shaft on the additional unit 19, transit drums 18 and fixed ends with them on the counterweight 8, is flexible, causes the rotation of the additional unit 19 and transit drums 18, one of which is kinematically connected to the sensor I, issuing signals to the remote control. The lack of slippage of the flexible connection (rope) 20 on the transit drums 18 ensures that the angle of rotation of the sensor 11 corresponds to a certain position of the counterweight 8.

The proposed technical solution provides a significant improvement in conditions.

operation, namely; reducing operator fatigue due to the fact that information on the position of the counterweight is fed to the remote control continuously, in the form of, for example, a smooth deflection of the instrument or a light beam

on the screen, which is more convenient for perception than the flashing of indicator lamps characteristic of discrete output of information, and an increase in reliable information about the position of the counterweight by eliminating "dead zones."
