A Maintenance and Protection System for Marine Traction Drive Elevator

Abstract

The invention relates to an overhaul protection system for a marine traction drive lift. A fixed seat (1) is fixed to the ground of a marine lift pit; the bottom of a stand column (5) is connected with the fixed seat (1) through a hinge, and the stand column (5) can rotate around the hinge; one end of a steel wire rope (7) is fixed to the upper end of the stand column (5), and the other end of the steel wire rope (7) is guided by a guiding wheel (8) and then wound in a rope winder (9); a first stretching spring (3) and a second stretching spring (4) are used for stretching the stand column (5) so as to maintain the stand column (5) in a vertical state. According to the overhaul protection system, on the premise that the requirements of a cube are met, and under the condition that the height of a top layer of a marine lift shaft and the depth of the pit cannot meet the requirement of a safety distance, the effect that the marine lift has enough safety space is guaranteed while fewer total resources are occupied through the joint action of a mechanical device and an electrical device, and therefore the marine lift meets the requirements of a specification; the lift can be used during overhaul operation, and thus safety of overhaul staff is effectively protected in narrow space of a ship.

Description

technical field [0001] The invention relates to the field of ships, in particular to a maintenance and protection system for a marine traction drive elevator. Background technique [0002] Nowadays, land-use elevators are becoming more and more commercialized, with a high degree of standardized design. Generally, a standard elevator specification is selected at the early stage of building design, and then a matching hoistway space is reserved in the building according to this specification. Marine elevators are special equipment. Unlike land elevators, marine elevators are usually equipped with hull reinforcements on the top, wall and bottom of the well, and the space around the well is very small. [0003] For marine passenger elevators, inspection boxes are installed above the car and in the pit, and elevator-related devices such as speed limiters and speed governor tensioning devices are also installed on the top of the well and in the bottom pit; As far as freight elev...

AI Technical Summary

Problems solved by technology

[0019] The purpose of the present invention is to provide a maintenance and protection system for marine traction drive elevators in order to solve the design problems of making the marine elevator meet the standard safety space requirements when the space of the ship's well is narrow and the height of the top floor and the depth of the pit are insufficient. , which can ensure enough safety space for the marine elevator while occupying less overall resources of the ship, so that the marine elevator can meet the requirements of the code, and then effectively protect the safety of the maintenance personnel in the small space on the ship
