Description

Technical Field

[0001] The utility model relates to the technical field of winch-type vertical ship lifts, and specifically relates to a locking structure for a ship lift platform in a shipyard for ship docking and launching. Background Technique

[0002] A winch-type vertical ship lift consists of parts such as the port basin of the ship lift, the ship-holding platform, the suspension point device, and the control system. When a ship enters the port basin, the ship lands on the piers preset on the ship-holding platform. Under the action of the suspension point device, the ship-holding platform lifts the ship to the ground elevation of the land parking station, locks the ship-holding platform, and then the ship transfer system transports the ship to the land parking station. The ship launching process is opposite to the ship lifting process.

[0003] The ship lift is configured with multiple suspension points, which are generally symmetrically arranged on both sides of the port basin. The suspension point consists of parts such as a fixed pulley set, a locking device, and a winch. The ship-holding platform is the carrier of the ship. Hanger structures extend out on both sides of the ship-holding platform, and movable pulley sets are installed on the hanger structures. The winch is the power device for the lifting and lowering of the ship-holding platform and the ship. By winding in or releasing the rope of the winch, the platform is lifted and lowered together with the ship. The steel wire rope passes through the fixed pulley set and the movable pulley set to connect the winch and the ship-holding platform, and realizes the function of increasing force and reducing speed. When the ship-holding platform reaches the same height as the ground of the land parking station, through the locking device, the ship-holding platform is rigidly connected to the suspension point steel, facilitating the ship transfer operation and the pier layout operation.

[0004] The locking device of the existing ship lift platform uses a power push rod to push a bolt, and the bolt rigidly connects the hanger structure of the ship-holding platform to the fixed support for locking on the port basin. To improve the capacity, generally multiple groups of movable pulleys are used, corresponding to multiple groups of hanger bolt plates, and are connected by a single bolt. The size is long, and it is required that the hanger bolt plate and the fixed support are accurately aligned to insert the bolt smoothly. However, the ship lift belongs to large-scale heavy-duty equipment, and the line load of the ship is uneven, and different ships have different loads. Therefore, the loads on each suspension point are different. When in different states of load and no-load, the deformation of the platform is different, and when the load is different, the deformation of the platform is different. The bolt holes of the hanger bolt plate are affected by the deformation of the platform, and the alignment position will be deflected and displaced. Constrained by various factors such as size, the clearance between the hole and the shaft is limited and cannot be infinitely enlarged. In actual engineering, due to the deviation of the hole from the axis, it is difficult to insert and pull out the bolt. Content of the Utility Model

[0005] The purpose of the utility model is to provide a locking structure for a ship lift platform in a shipyard for ship docking and launching, so as to solve the problems raised in the above background technique.

[0006] To achieve the above object, the present utility model provides the following technical solution: A locking structure for a shipyard ship lift platform for ship docking and launching, including a hanger structure and a locking support provided on the pool wall of the harbor basin. The hanger structure is integrally connected to the ship-carrying platform of the ship lift. Pulling plates are provided on both sides of the hanger structure. The pulling plates are arranged on both sides of a movable pulley, and the movable pulley is connected to the fixed pulley set of the ship lift by a traction cable. A spindle is provided at the axis center of the movable pulley, and a bushing is inlaid on the spindle. The bushing is a sliding bearing and is sleeved on the outside of the spindle. A pear-shaped hole is provided at the upper part of the pulling plate, and pin shafts are provided on both sides of the locking support. The two ends of the pin shafts are correspondingly installed in the pear-shaped holes.

[0007] Preferably, the diameter of the upper circular hole of the pear-shaped hole is smaller than the diameter of the lower circular hole, and both are larger than the diameter of the pin shaft.

[0008] Preferably, a counterweight is provided at the bottom end of the pulling plate. The counterweight is fixedly connected to the pulling plates on both sides of the hanger structure by bolts, and the pulling plates on both sides and the counterweight are symmetrically arranged.

[0009] Preferably, the locking support is provided with a connecting plate. The connecting plate is a rectangular plate, and a jack coaxial with the pin shaft is provided on the connecting plate. The pin shaft is inserted into the connecting plate through the jack. The pulling plate is inserted and supported inside the connecting plate, and the pin shaft passes through the pear-shaped hole of the pulling plate.

[0010] Preferably, multiple groups of movable pulleys are arranged side by side.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: Compared with the prior art that uses long insertion pins at each hanging point to fix the ship-carrying platform of the ship lift, the present utility model uses a pair of short pin shafts, which greatly reduces the difficulty of inserting pins and reduces the equipment failure rate. The designed pulling plate counterweight structure enables the ship-carrying platform to maintain the vertical posture of the hanger structure under various different ship conditions, and has the advantages of simple structure and easy maintenance. By utilizing its own structural characteristics, the reliability of pin insertion is significantly improved, so that the ship-carrying platform and the hanger structure are locked on the side wall of the harbor basin, facilitating ship moving operations and pier laying operations, and further improving the safety performance.

[0021] Please refer to Figures 1-5, the present utility model provides a technical solution: a locking structure for a shipyard ship lift platform for ship docking and launching, including a hanger structure 1 and a locking support 3 provided on the port basin wall. The hanger structure 1 is integrally connected to the ship lift ship carrying platform 2; on both sides of the hanger structure 1, there are pull plates 5. The pull plates 5 are arranged on both sides of the movable pulley 6, and the movable pulley 6 is connected to the fixed pulley group of the ship lift through a traction cable; at the axis of the movable pulley 6, there is a spindle 7, and a bushing 8 is inlaid on the spindle 7. The bushing 8 is a sliding bearing and is fitted outside the spindle 7; at the upper part of the pull plate 5, there is a pear-shaped hole 9, and on both sides of the locking support 3, there are pin shafts 4. The two ends of the pin shaft 4 are respectively installed in the pear-shaped hole 9.

[0022] Further, the diameter of the upper circular hole of the pear-shaped hole 9 is smaller than the diameter of the lower circular hole, and both are larger than the diameter of the pin shaft 4.

[0023] Further, at the bottom end of the pull plate 5, there is a counterweight 10. The counterweight 10 is fixedly connected to the pull plates 5 on both sides of the hanger structure 1 through bolts, and the pull plates 5 on both sides and the counterweight 10 are symmetrically arranged.

[0024] Further, the locking support 3 is provided with a connecting plate 11. The connecting plate 11 is a rectangular plate, and there is a jack coaxial with the pin shaft 4 on the connecting plate 11. The pin shaft 4 is inserted into the connecting plate 11 through the jack; the pull plate 5 is inserted and held inside the connecting plate 11, and the pin shaft 4 passes through the pear-shaped hole 9 of the pull plate 5.

[0025] Further, multiple groups of the movable pulleys 6 are arranged side by side.

[0026] Working principle: The hanger structure 1 is integrally connected to the ship lift ship carrying platform 2, and a pair of pin shafts 4 in the hanger structure 1 and the locking support 3 provided on the port basin wall realize the locking of the ship lift.
