Problems solved by technology

[0002] When the ship lift cabin equipment is maintained or overhauled, it is necessary to stop the ship lift cabin at a certain height, and it needs to be stopped for a long time during centralized maintenance. state, the ship compartment cannot be displaced vertically during this period. At this time, the ship compartment lacks a safe and reliable parking protection device. The safety risk of displacement in the direction is greater, so it is necessary to add an inspection locking device in the vertical direction of the ship lift cabin to ensure that the ship lift cabin can be safely and reliably stopped for long-term maintenance, and at the same time the locking device is in a non-working state , it cannot affect the normal lifting operation of the ship lift cabin

Embodiment Construction

[0044] Such as figure 1 As shown in the figure, a locking device for ship lift cabin maintenance includes an upper guide frame system 1, an upper locking block 2, a lower locking block 3, a transmission shaft 4, a lower guide frame system 5, a rotation adaptation mechanism 6, and a rotation center rod 7. Hinged support shaft 8, nut column 9, ship box structure 10, ship box transmission system 11. Specifically, the transmission shaft 4 is located at the upper end of the hinged support shaft 8 , and the transmission shaft 4 can rotate relative to the hinged support shaft 8 . The lower guide frame system 5 is installed and matched with the lower part of the transmission shaft 4, and the lower guide frame system 5 is driven to rotate by the cabin transmission system 11 and then drives the transmission shaft 4 to rotate. The rotation center rod 7 is fixedly connected to the upper end of the transmission shaft 4, and the rotation center rod 7 also rotates during the rotation of the...

Abstract

A locking device for maintenance of a ship chamber of a ship lift mainly comprises an upper guide frame system, and the upper guide frame system is installed on an upper locking block and makes contact with the side face of a nut column. The upper locking block is assembled on the upper side wall of the rotating center rod and forms a closed oil cavity with the rotating center rod; the lower locking block is assembled on the lower side wall of the rotating center rod and forms a closed oil cavity with the rotating center rod; a transmission shaft is fixed to the lower end of the rotating center rod, and a lower guide frame system is installed on the outer side wall of the transmission shaft, makes contact with the side face of the nut column and is driven by a ship chamber transmission system to rotate. The bottom end of the transmission shaft is rotationally connected with the hinge supporting shaft. The other end of the hinge supporting shaft is connected with a ship chamber structure; the rotary adaptation mechanism is installed at the top end of the rotary center rod and connected with the hydraulic system. The locking device for overhauling the ship chamber of the ship lift and the method of the locking device have the advantages of being good in safety and reliability, exquisite in structure, easy to operate, convenient to install and the like.

Description

technical field [0001] The invention relates to a ship lift, in particular to a locking device and a method thereof for maintenance of a ship compartment of a ship lift. Background technique [0002] When the ship lift cabin equipment is maintained or overhauled, it is necessary to stop the ship lift cabin at a certain height, and it needs to be in a stopped state for a long time when it is centralized for maintenance, and the vertical direction of the cabin cannot occur during this period. At this time, the ship compartment lacks a safe and reliable parking protection device, especially when the water depth of the ship lift compartment changes and other abnormal conditions, the safety risk of the ship compartment displacement in the vertical direction is relatively large, so it is necessary to A maintenance locking device is added to the vertical direction of the ship lift cabin to ensure that the ship lift cabin can be safely and reliably stopped for long-term maintenance....
