Description

Ship lifters for light-duty vessels are known, made in the form of a track going from one pool to another through a dam along which the ship-lifting trolley does not move. The carriage is moved with the help of two winches, and the carriage consists of two parts, which are movably located one from the other case.

Such ship elevators, in order to automatically ensure the horizontal position of the lifted |: one, regardless of the track gradient, have relatively complicated constructions.

In the proposed ship elevator, the automatic retention of the horizontal position of the lifted vessel, independent of the slope of the track, is achieved by simpler and more reliable means. The essence of the invention is that the upper carrier part of the lifting trolley is provided with downwardly curved arcuate rails supported on rollers mounted with balances on the bottom legs.

FIG. 1 shows a diagram of a ship elevator in profile; in fig. 2- front view.

The ship lifting trolley consists of the upper part of the platform / on which the vessel 2 is mounted and the lower part 5 with wheels 4. The platform / is equipped with two longitudinal arcuate rails 5 connected to it. The platform is installed by these rails on the upward-facing rollers 6 of the balances 7 which are fixed on the racks of the lower part of 3 carts.

The frame of the lower part of the trolley with the help of balancers 8 with wheels 4 is installed on the rails 9 of the track and the ship thus transports: from one pool to another.

The ship lifting trolley is moved by two automatically operating winches by means of ropes 10.

When the cart moves from the ship to the dam crest, the ship automatically rolls on the rollers 6 under its own weight and the weight of the platform, which is mounted on the rollers, in a horizontal position.

When the cart is on the crest of the dam, the platform with the vessel will take a middle position relative to the lower part of the taiga. When moving the trolley with the vessel to the inclined part of the dam of another pool, the platform with the vessel will also maintain a horizontal position during movement.

The design of the proposed ship elevator automatically provides for a relatively simple means of horizontal positioning of the vessel regardless of the slope of the track.

Subject invention

A ship lift for ships of small carrying capacity, made in the form of a rail track running from one bay to another through a dam, along which the ship lifting cart, consisting of two moving parts of one relative but different parts, different in that, with the aim of automatically ensuring the horizontal position of the lifted, regardless of the slope of the track, the upper carrier part of the ship-lifting carriage is equipped with downwardly curved arcuate rails resting on rollers mounted by balancing on the bottom cart posts.
