On-way locking device of ship reception chamber of ship lifter

Abstract

The invention discloses an on-way locking device of a ship reception chamber of a ship lifter. The on-way locking device comprises fixed brackets, a movable bracket, guide-support bodies, horizontal oil cylinders, shaft housings, vertical oil cylinders and shear plates, which are arranged outside an outer web of a main longitudinal girder of the ship reception chamber, wherein the at least two fixed brackets are symmetrically distributed on the upper and lower ends of the movable bracket; the movable bracket comprises an upper cross beam, a lower cross beam, a longitudinal beam and a base plate, the upper cross beam and the lower cross beam are connected through the longitudinal beam, and the base plate is located on the side faces of the cross beams and the longitudinal beam and is used for connecting the cross beams with the longitudinal beam; both two ends of the at least two guide-support bodies are connected with the cross beams through bolts; the at least four shear plates are symmetrically distributed in the fixed brackets. The on-way locking device has the beneficial effects that the on-way locking device is prevented from contacting tracks to be damaged during the lifting process of the ship reception chamber, the locking at random elevation under a butt joint or emergency situation is achieved, the cost is lowered, and a self-protective function is achieved.

Description

technical field [0001] The invention relates to an along-way locking device for a ship-bearing compartment of a ship lift, and belongs to the technical field of auxiliary facilities for ships crossing dams. Background technique [0002] The ship lift is a device commonly used for lifting and lowering the ship when the ship passes the embankment with a water level drop. After the ship-holding box of the ship lift is docked with the lock head, due to the movement of the ship in and out of the ship-holding box, the water body in the ship-holding box will increase or decrease, thus causing the ship-holding box to generate a vertical load; at the same time, the ship-holding box is lifted to At any height, if the equipment fails and needs to be evacuated or repaired, vertical load or shaking will inevitably occur. In order to avoid the occurrence of the above situation and from a safety point of view, it is necessary to set up a locking device along the way. [0003] The locking...

AI Technical Summary

Problems solved by technology

[0003] The locking device currently used mainly has the following problems: Since the ship-bearing box itself has longitudinal and transverse guides, the guide wheels on the locking device limit its own deviation, which will lead to damage to the locking device; the top rod and bottom rod of the frame Connected by connecting rods, the rigidity is obviously very small; the inner wall of the guide requires high processing precision and is easy to wear, and the replacement cost is high; it can only meet the docking locking of the navigable water level change range, and cannot meet the locking of any elevation in emergencies; The track installation accuracy of the device is not high, the current technology meets the requirements, and the oblique hydraulic-pneumatic spring cylinder is cumbersome
