Description

Technical Field

[0001] The utility model relates to the technical field of ramming integrated ship construction, in particular to a control system for the retraction and extension of a stone throwing chute device of a ramming integrated ship. Background Technique

[0002] At present, the existing stone throwing chute device of a ramming ship is provided with a stone throwing trolley. The upper part of the trolley is an aggregate hopper, and a chute for guiding the material to fall is connected below the hopper. The connection mode between the two is fixed by a rotatable hinge and three eye plate pins. The chute is generally composed of 1-3 telescopic sleeves. The sleeve connected to the hopper pin is the inner sleeve, and the outer telescopic sleeve is lifted by two winches arranged on the stone throwing platform. After the telescopic sleeve is retracted, a fixing pin on the pipe body is inserted into the pin holes of the inner and outer sleeves for locking.

[0003] The existing method for retracting and extending the chute is that there is a rotatable shelf on the ship's side at the position for retracting and extending the chute on the main deck of the ship, and a winch for lifting and lowering the chute is separately arranged on the main deck of the ship. The winch steel wire rope passes through the pulley on the retraction and extension support and is connected to the bottom lifting lug of the outer pipe of the chute. The chute is lifted by the action of the winch and placed on the shelf on the ship's side to make the chute placed in a horizontal state; when lowering, the end of the chute is lifted by the traction of the winch steel wire rope, and after the shelf is rotated back to the ship's side, the chute is released and lowered by the winch steel wire rope to make the chute in a vertical natural state.

[0004] The above existing method has the following deficiencies: when the chute is lowered to a vertical state, the end of the retraction and extension winch traction cable is connected to the bottom lifting lug of the pipe, and this connection position is more than 10 meters underwater, which is not convenient to disconnect, and the unlocking requires the cooperation of divers; if the stone throwing chute device operates with the retraction and extension steel wire rope, the moving distance of the stone throwing chute device on the track is limited, and the operation of synchronizing the movement of the stone throwing device and the winch steel wire rope for lifting and lowering the chute is complex, with poor efficiency, and the lifting and lowering steel wire rope is dragged underwater, reducing the safety. Content of the Utility Model

[0005] The purpose of the utility model is to provide a control system for the retraction and extension of a stone throwing chute device of a ramming integrated ship to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A control system for the retraction and extension of a stone-dropping chute pipe device on a ramming and leveling integrated ship, characterized in that: it includes a chute pipe winch one and a chute pipe winch two symmetrically fixed on the bottom surface of the trolley of the stone-dropping chute pipe device. The chute pipe winch one and the chute pipe winch two are respectively connected to a universal fairlead one and a universal fairlead two through steel wires. The steel wires of the two fairleads are respectively fixed on the lifting lugs at the bottom of the telescopic sleeve of the chute pipe. A steel wire clamp is fixedly connected to the steel wire of the chute pipe winch two; both sides of the telescopic sleeve are connected with sleeve pins, and the top is connected with an eye plate. Three fixed pin shafts are connected to the outside of the eye plate; it also includes a lifting frame connected to the deck on the side where the chute pipe is retracted. A suspension rod is connected to the lifting frame. The upper end of the suspension rod is connected to a small winch. A single-sheave pulley is fixedly connected to the lifting frame. An anti-typhoon shelf is arranged between the lifting frame and the telescopic sleeve.

[0008] The anti-typhoon shelf is a set of two, and a groove for placing the telescopic sleeve is opened on it. A pipe clamp for fixing the telescopic sleeve is connected to the groove. The anti-typhoon shelf is connected to the ship's side through a rotating shaft. A limit block for positioning it is arranged on one side of the anti-typhoon shelf.

[0009] The utility model is a control system for the retraction and extension of a stone-dropping chute pipe device on a ramming and leveling integrated ship. A lifting frame is arranged on the side of the main deck of the ship. A fixed pulley and an inclined suspension rod are arranged on the lifting frame. A small winch is installed on the suspension rod. The steel wire of the right chute pipe winch on the chute pipe trolley is led to the directional pulley on the lifting frame, and the retraction and extension of the telescopic sleeve on the anti-typhoon shelf can be realized. It effectively solves the problem of untying the steel wire underwater, saves the equipment cost of a traction winch, and is convenient and applicable. Brief Description of the Drawings
