Embodiment Construction

[0010] like figure 1 As shown, the downstream incoming ship is driven into the ship-bearing compartment 1 in the dam, and the left and right outer rotor motors 7, 7' are started, and the front drum 10 of the left outer rotor motor 7 rotates counterclockwise, while the front drum 10 of the right outer rotor motor 7' rotates counterclockwise. The drum rotates clockwise, and the ship-carrying box 1 and the ship are raised to the required height through the left and right ship-carrying car belts 2, 2', and the left and right counterweights 4, 4' are lowered by the counterweight at the same time; The belts on the heavy side are used in multiple sets. When one of them breaks, the other one continues to work normally, waiting for maintenance, so as to avoid the sudden drop of the counterweight or the loss of balance of the carrier box, which will cause safety accidents.

Abstract

The invention discloses a ship lifting device, and belongs to the technical field of mechanical lifting. A ship reception chamber is placed on water surface between a left dam body and a right dam body, wherein the two sides of the ship reception chamber are connected with ship reception chamber belts respectively; the upper ends of the ship reception chamber belts are connected with front revolving drums of left and right outer rotor motors through first guide wheels on the left and right dam bodies; left and right counterweights are hung on the outer sides of the left and right dam bodies respectively; counterweight belts connected with the left and right counterweights are connected with rear revolving drums of the left and right outer rotor motors through second guide wheels on the left and right dam bodies; the left and right outer rotor motors and lifting mechanisms thereof adopt the same structures, and are symmetrically arranged on the left and right dam bodies; front and rear center shafts of the single outer rotor motors are fixedly mounted on the dam bodies through brackets; the circumferential surfaces of the front and rear revolving drums are connected with the ship reception chamber belts of which the lower ends are connected with the ship reception chamber and the counterweight belts of which the lower ends are connected with the counterweights through screws respectively; front and rear brakes are mounted at the middle positions of the front and rear revolving drums. The outer rotor motors are utilized, so that the ship lifting device is simple in structure, convenient to control and high in transmission efficiency, and saves energy.

Description

technical field [0001] The invention belongs to the technical field of mechanical lifting, and in particular relates to a ship lifting device. Background technique [0002] At present, in the field of shipping at home and abroad, there are many devices used to lift ships to a certain height, such as electric hoist hoist, rack and pinion transmission hoist, hydraulic drive hoist, etc. Among them, electric hoist is more used for the hoisting of small ships. , but its disadvantage is that the transmission mechanism is complicated, the transmission efficiency is low, and the safety is poor. Contents of the invention [0003] The object of the present invention is to provide a novel ship-elevating device, which can overcome the shortcomings of the prior art. [0004] The present invention is achieved like this, and its structural feature is as figure 1 As shown, on the water surface between the left and right dam bodies 3, 3', there is a ship-holding box 1, the left and r...
