Description

Technical Field

[0001] The utility model belongs to the technical field of ship lifts, and in particular relates to a hydraulically driven connecting rod bracing type ship lift ship compartment docking and locking device. Background Art

[0002] When the ship carriage of the fully balanced vertical ship lift is docked with the upstream and downstream waters, it is generally necessary to lock the ship carriage on the tower column through a docking locking device to prevent the ship carriage from vertically displacing during the docking period. In engineering, a docking locking device that relies on static friction for locking is often used. This docking locking device is generally divided into four groups and symmetrically arranged on both sides of the ship carriage. Each group of locking devices has a locking frame. The locking frame is provided with transverse and longitudinal guide wheels, which are connected to the ship carriage through a supporting cylinder and pressed into a vertical groove on the tower column by a hydraulic spring. When not locked, the entire device can move up and down in the tower column groove with the ship carriage. When docking and locking are performed, the locking cylinders on both sides of the locking frame are pushed out, and the friction plates with high friction coefficients on the end faces of the cylinders are tightly supported on the friction surfaces of the track embedded parts. The static friction generated can realize the vertical locking of the ship carriage.

[0003] When docking and locking are performed, the locking cylinders on both sides of the locking frame are pushed out, and the friction plates with high friction coefficients on the cylinder end faces are braced against the friction surfaces of the rail embedded parts. The static friction force generated can achieve vertical locking of the ship-bearing compartment. However, on the one hand, too many locking cylinders will lead to an increased equipment failure rate. At the same time, due to the limited space in the tower column groove, the cylinder bodies of the locking cylinders are all set in the guide grooves on the locking frame and are difficult to remove directly. When the locking cylinders are inspected or replaced, the entire docking locking device needs to be disassembled and lifted out of the tower column groove, which makes inspection and maintenance more difficult.

[0005] The purpose of the utility model is achieved through the following technical solutions:

[0006] A hydraulically driven connecting rod tightening type ship lift cabin docking locking device comprises a locking frame and a plurality of guide assemblies arranged in the locking frame, each of the guide assemblies comprising guide grooves located on the left and right sides of the locking frame, the plurality of guide assemblies are arranged in the vertical direction, the guide grooves on the left and right sides are provided with locking pins, there is an installation gap between the locking pins in the same group of guide assemblies, a locking cylinder is arranged between two adjacent groups of guide assemblies, the locking cylinder extends in the vertical direction, and its two ends are respectively located in the installation gaps between the two adjacent groups of guide assemblies, the end of the locking cylinder is hinged to the locking pins on both sides of the installation gap, and the two ends of the locking cylinder can be extended or retracted in the vertical direction to allow the end face of the locking pin to contact or separate with the track embedded parts in the tower column groove.

Through this embodiment, the vertical plates of the locking frame avoid the locking cylinder and provide a through hole for the installation of the guide groove, which facilitates the removal or installation of the locking cylinder from the side when disassembling and assembling the locking cylinder.

[0008] In one embodiment, the guide grooves in each group of the guide assemblies are symmetrically arranged along the vertical center line of the locking frame.

Through this embodiment, the provided limiting portion can control the retraction position of the locking pin when the ship compartment is contact-locked, thereby solving the problem of the locking pins on both sides of the locking cylinder retracting asynchronously even if they are asynchronous due to the difference in retraction resistance, and ensuring that when the locking cylinder retracts, the locking pins on both sides can be retracted and disengaged from the friction surface one after another.

[0010] In one embodiment, the limiting portion is an annular structure, which is fixed at the end of the guide groove, and its inner diameter is smaller than the diameter of the locking pin.

Each connecting rod is hinged to a corresponding locking pin. Through this embodiment, the connecting rod and the axis of the locking cylinder form a Y-shaped structure, so that when a locking cylinder is extended or retracted in the vertical direction, it can simultaneously drive the four guide pins in two adjacent groups of guide assemblies to extend or retract, thereby greatly reducing the number of required locking cylinders and alleviating the workload of maintenance and overhaul.

[0015] In one embodiment, a gas spring mounting beam is further provided on the vertical plate, an inclined gas spring is hingedly connected to the middle portion of the gas spring mounting beam, a supporting oil cylinder is also hingedly connected to the bottom of the locking frame, and both the gas spring and the supporting oil cylinder are used to be hinged to the ship carrying compartment. Through this embodiment, the gas spring mounting beam is provided on the vertical plate, which not only facilitates the removal of the gas spring mounting beam, but also facilitates the disassembly and assembly of the locking pin in the locking frame.

[0016] The beneficial effects of the utility model are:

[0017] (1) The locking cylinder and the locking pin are separately arranged. The locking pin is arranged in the guide groove. The locking cylinder extends in the vertical direction. The two ends of the locking cylinder are respectively arranged in the installation gaps of the two adjacent guide assemblies. Each end of the locking cylinder is hinged with the two locking pins in the same guide assembly. When the locking cylinder is pushed out, the two locking pins in the two adjacent guide assemblies are simultaneously pushed to move toward the friction surfaces on both sides thereof. The mechanism relies on static friction force to achieve the locking relative position with the friction surface. This not only facilitates the disassembly and assembly of the locking cylinder, but also greatly reduces the number of locking cylinders required, thereby reducing the workload of maintenance and overhaul.

[0018] (2) The limit portion provided can prevent the locking pins from being retracted asynchronously due to the difference in retraction resistance, and ensure that when the locking cylinder retracts, the locking pins on both sides can be retracted and disengaged from the friction surface in turn, that is, the locking pins on both sides of each locking cylinder with the smaller retraction resistance will be retracted first until it is restricted by the limit ring, and then the other locking pin will be retracted. When all the locking pins are retracted, the vertical lock of the ship compartment is released. BRIEF DESCRIPTION OF THE DRAWINGS
