Description

Technical Field

[0001] The utility model relates to the technical field of shipbuilding equipment, and more specifically, to a knife gate chain stopper device. Background Art

[0002] The function of the knife gate chain stopper is to be arranged between the anchor winch and the anchor chain pipe, used to fix the anchor chain and prevent the anchor chain from slipping out. When at anchor, the chain stopper transmits the tension generated by the anchor and the anchor chain to the hull to reduce the load on the anchor winch and protect the anchor winch. During navigation, it bears the gravity and inertia force of the anchor. Since the height of the anchor winch is usually relatively high and the height of the anchor chain coming out of the anchor winch is also relatively high, the knife gate chain stopper needs to cooperate with a base of a certain height to be fully utilized.

[0003] However, after the existing knife gate chain stopper is used for a period of time, the anchor chain extends and becomes longer under the action of the gravity of the anchor and the repeated pulling of the anchor winch. There is a gap in the limit of the braking part of the knife gate on the anchor chain link, which easily causes the anchor and the anchor chain to swing continuously under the action of surges, and is extremely likely to cause abnormal noise and collision accidents, affecting the chain stopping effect of the chain stopper.

[0039] The chain switching member includes a chain locking member, a locking transmission member and a locking power member. The chain locking member and the locking power member are both arranged on the chain supporting seat 1, and the locking transmission member is arranged on the chain locking member and the locking power member. The chain locking member includes a locking guide block 10 and a locking shaft 11. The locking guide block 10 is in the shape of a rectangular block. One side edge of the locking guide block 10 is vertically fixed on the front side surface of the chain supporting seat 1, and the longitudinal line of the locking guide block 10 is perpendicular to the chain locking plate 4. There are two locking guide blocks 10, and the two locking guide blocks 10 are arranged in parallel at intervals to provide sliding guidance for the locking shaft 11. The locking shaft 11 is integrally in the shape of a rectangular column, one end of the locking shaft 11 is wedge-shaped, and the locking shaft 11 is slidably fitted between the two locking guide blocks 10. When the locking shaft 11 is vertically pushed upward by the locking power member, one end of the locking shaft 11 will be inserted into the locking hole on the chain locking plate 4. The locking hole is in the shape of a wedge-shaped hole.

[0040] The locking transmission member includes a locking pulling member and a locking anti-loosening pushing member. The locking pulling member is arranged on the locking shaft 11, and the locking anti-loosening pushing member is arranged on the locking pulling member. The locking pulling member includes a guiding shaft 12 and a pulling slider 13. One end of the guiding shaft 12 is slidably fitted in the guiding hole on the other end face of the locking shaft 11.

One end of the pulling slider 13 passes through the pulling through hole 14 on the side wall of the locking shaft 11 and is fixedly connected to the side wall of one end of the locking shaft 11. Further, the pulling through hole 14 is in the shape of a long hole and is not through with the other end face of the locking shaft 11. When one end of the guiding shaft 12 slides in the guiding hole, it will drive the pulling slider 13 to slide in the pulling through hole 14. When one end of the guiding shaft 12 slides outwards to the limit, it will drive the locking shaft 11 to move downwards through the pulling slider 13, and then pull out one end of the locking shaft 11 from the locking hole to release the horizontal locking of the chain locking plate 4.

[0041] The locking anti-loosening pushing member includes a pushing backing plate 15 and a spring 16. The pushing backing plate 15 is horizontally and fixedly arranged on the other end of the guiding shaft 12. After the spring 16 is sleeved on the guiding shaft 12, one end of the spring 16 is connected to the pushing backing plate 15, and the other end of the spring 16 is connected to the other end face of the locking shaft 11.

[0043] Before the anchor chain needs to be locked after weighing anchor is completed, the push rod 17 shortens until the locking shaft 11 is pulled out of the locking hole through the pulling slider 13, so that the chain locking plate 4 is in a horizontal free state, that is, the chain mounting seat 2 and the chain sliding plate 3 are also in a horizontal free state, and then the anchor chain is locked through the knife gate chain stopper; when the anchor chain is under the action of the gravity of the anchor and the repeated pulling of the anchor winch, it will drive the anchor chain to move back and forth. The anchor chain pulled back and forth drives the chain mounting plate and the chain sliding plate 3 to slide back and forth. The chain sliding plate 3 sliding back and forth transmits the force to the chain support seat 1 through the shock absorption buffer pad 7, avoiding the extension and deformation of the anchor chain.

[0044] Furthermore, two sets of chain locking switches are provided, and the two sets of chain locking switches correspond to the two chain locking plates 4 one by one.

By changing the position where the anchor chain is stuck in the guillotine chain stopper and avoiding the worn area of the anchor chain, it is ensured that the guillotine chain stopper and the anchor chain are tightly engaged again.

[0046] The chain locking seat 19 is in a block shape. The bottom surface of the chain locking seat 19 is welded to the top surface of the chain locking flat plate 18. The top surface of the chain locking seat 19 is in an inclined shape, and a chain guiding groove is provided on the top surface of the chain locking seat 19 to allow the anchor chain to slide down from the top surface of the chain locking seat 19 during the anchoring process. The chain locking side plates 20 are fixedly arranged on the side edges of the chain locking seat 19, and the two chain locking side plates 20 are correspondingly arranged on the two side surfaces of the chain locking seat 19 one by one. The gate plate can be slidably fitted into the locking grooves on the chain locking side plates 20 to lock the anchor chain on the chain locking seat 19.
