Problems solved by technology
The disadvantage is that the experience trial operation technology is not a real adjustable technology, but more inclined to the traditional experience design, which cannot control the gap mutation caused by various emergencies, and it is difficult to fundamentally guarantee the safe operation of the ship lift

The invention relates to a method and device for adjusting a thread pair gap of a safety mechanism of a gear and rack climbing type ship lift. A closed-loop control system with detecting and adjustingfunctions is designed and used for detecting and adjusting the thread pair gap of the safety mechanism, and comprises a thread pair gap monitoring device, a control system and an adjusting system, wherein the monitoring device is used for monitoring the thread pair gap, the control system starts the adjusting system according to the gap data fed back by the monitoring device, and according to theadjusting system, a worm and gear differential adjusting device and an additional rotating device are additionally arranged to adjust the original output on the basis that the original bevel gear matched input and output are not changed. When the gap value exceeds an allowable range, the additional rotating device receives a signal transmitted by a millimeter-scale laser distance measuring sensor, regulates and controls the worm and gear differential device and controls the output rotating speed, so that the gap of the matching position of a screw and a nut column in the safety mechanism is regulated, and the gap is changed back to the allowable range.
Description
technical field [0001] The present invention relates to the field of ship lift operation safety equipment, in particular to a method and device for adjusting the gap between screw threads of a rack and pinion climbing type ship lift safety mechanism. Background technique [0002] The thread pair clearance between the safety mechanism screw rod and the nut column is a very important parameter of the rack and pinion climbing ship lift. The ideal gap value should be moderate. If it is too large, it will cause unnecessary increase in the equipment scale of the safety mechanism and driving mechanism. If it is too small, it will affect the normal operation of the ship lift. However, in engineering, due to the influence of factors such as the manufacturing error of the transmission system, the displacement of the tower column and the ship's box, and the manufacturing and installation error of the equipment, the clearance of the thread pair will change randomly during the lifting pr...
