Description
Technical Field
The utility model relates to the technical field of underwater cutting, in particular to a passive heave compensation device for underwater cutting.
Background
The cutting of underwater structures is carried out by using a diamond wire saw, wherein a wire saw machine is generally arranged on a ship, a cut object is positioned on the sea bottom, and the wire saw machine moves along with waves due to the influence of the waves, so that the diamond wire saw is broken and other faults are caused. For this reason, a simple passive heave compensation system is introduced to keep the diamond wire saw tension substantially constant, thereby ensuring that normal cutting operations can still be performed under large waves.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a passive heave compensation system, wherein the gravity constant tension value of the compensation system is adjustable, a compensation channel is stable, and the compensation stroke is larger than the heave displacement of a floating platform where a rope sawing machine is positioned.
In order to solve the technical problems, the utility model adopts the following technical scheme: the utility model provides a passive heave compensation device of underwater cutting, includes engineering ship and rope saw, the rope saw sets up on the deck of engineering ship, still includes and decides the leading wheel and move the leading wheel, it is first and decides the leading wheel second to decide the leading wheel to be equipped with two respectively, decides leading wheel first and decides the leading wheel second and correspond the setting side by side on the deck, moves the leading wheel setting in guide rail frame, guide rail frame sets up in engineering ship side, and the diamond rope is drawn forth by the rope saw and is passed in proper order and decides leading wheel first, moves the leading wheel and decides the leading wheel second back and guide the cut thing.
Preferably, a guide rail is arranged in the guide rail frame, a guide wheel frame is arranged outside the movable guide wheel, and the guide wheel frame slides on the guide rail in the guide wheel frame.
Preferably, the bottom of the guide wheel frame is connected with the balancing weight through a steel wire rope.
By adopting the technical scheme of the utility model, the following beneficial effects can be obtained:
According to the underwater cutting passive heave compensation device, the compensation system is used for controlling constant tension through the movable pulley suspended weight, the weight of the suspended weight is adjustable, the space is controllable, the heave compensation range covers the up-and-down fluctuation travel of a sunken ship, and the device can be matched with a rope saw to realize stable cutting operation in a large-wave marine environment.
Drawings
The following is a brief description of what is expressed in the drawings of this specification and the references in the drawings:
FIG. 1 is a schematic diagram of the structure of the compensation device;
FIG. 2 is a schematic view of the structure of the present compensating device mounted on a floating vessel;
The labels in the above figures are: 1. engineering ship; 2. rope sawing machine; 3. a first fixed guide wheel; 4. a second fixed guide wheel; 5. a movable guide wheel; 6. a guide rail frame; 7. a guide rail; 8. balancing weight; 9. a diamond rope.
Detailed Description
The following describes the shape, structure, mutual position and connection relation between the parts, action and working principle of the parts, etc. of the specific embodiments of the present utility model, such as the related parts, will be further described in detail by describing examples.
As shown in fig. 1 and 2, the underwater cutting passive heave compensation device comprises an engineering ship 1 and a rope saw 2, wherein the rope saw 2 is arranged on a deck of the engineering ship 1, and further comprises a fixed guide wheel and a movable guide wheel 5, the fixed guide wheel is provided with two fixed guide wheels, namely a first fixed guide wheel 3 and a second fixed guide wheel 4, the first fixed guide wheel 3 and the second fixed guide wheel 4 are correspondingly arranged on the deck of the engineering ship 1 in parallel, the movable guide wheel 5 is arranged in a guide rail frame 6, the guide rail frame 6 is arranged on the side surface of the engineering ship 1, and a diamond rope 9 is led out by the rope saw 2 and sequentially passes through the first fixed guide wheel 3, the movable guide wheel 5 and the second fixed guide wheel 4 to guide a cut object.
The guide rail frame 6 is internally provided with a guide rail 7, the outside of the movable guide wheel 5 is provided with a guide wheel frame, the guide wheel frame slides on the guide rail 7 in the guide wheel frame 6, and the bottom of the guide wheel frame is connected with the balancing weight 8 through a steel wire rope.
As shown in fig. 1 and 2, the heave compensation structure is fixed at the side or the stern of the ship, the diamond rope in the wire saw 2 passes through the movable guide wheel 5, the balancing weight 8 is hung under the guide wheel frame of the movable guide wheel 5, and the structure is arranged at the passive side of the wire saw. The size of the balancing weight 8 is adjusted according to the cutting effect until the cutting parameters are in a reasonable and stable range, so that the tension of the diamond rope saw is kept basically constant, and normal cutting operation can be still performed under large waves. If the sea wave is large, the ship heave is large, the guide rail 7 needs to be lengthened, and the heave compensation range is enlarged. When the ship works, the stern is controlled by the anchoring, and the longitudinal and transverse movements of the ship are reduced.
While the utility model has been described above with reference to the accompanying drawings, it will be apparent that the utility model is not limited to the above embodiments, but is capable of being modified or applied directly to other applications without modification, as long as various insubstantial modifications of the method concept and technical solution of the utility model are adopted, all within the scope of the utility model.
