Suspension apparatus of ship main engine

Abstract

The invention relates to a suspension apparatus of a ship main engine. The suspension apparatus comprises wire ropes, and further comprises a suspension frame. A left end on the top of the suspension frame is connected with a first traction part through a first wire rope (111). A right end on the top of the suspension frame is connected with a second traction part through a second wire rope (211). A left end on the bottom of the suspension frame extends to a first suspension point (A) of a main engine (5) through a third wire rope (112). A right end on the bottom of the suspension frame extends to a fourth suspension point (D) of the main engine (5) through a fourth wire rope (212). A middle portion of the suspension frame is provided with space, wherein a middle wire rope passes through the middle portion of the suspension frame from top to bottom, and extends to a corresponding second suspension point (B) and a corresponding third suspension point (C) in the space. An upper end of the middle wire rope is connected with a third traction part. Compared to the prior art, the apparatus provided by the present invention has the following advantages that: the structure of the apparatus is simple; the pulley block is not required; the apparatus is easy to be used; the production cost of the apparatus is low; the suspension beam structure of the apparatus is solid and stable so as to provide longer service life.

Description

Technical field [0001] The invention relates to the technical field of a lifting device, in particular to a suspension device of a ship main engine. Background technique [0002] An existing Chinese utility model patent with the patent number 201020000967.7 titled "Multi-functional upper trolley crane beam for shipbuilding gantry cranes" discloses a multi-functional upper trolley crane beam for shipbuilding gantry cranes, including a beam, which is characterized by: on the beam Several pin shaft seats are fixedly arranged, two of the pin shaft seats are respectively hinged with a movable pulley mechanism, the mechanism includes a connecting arm, the upper end of the connecting arm is hinged on the pin shaft seat, the lower end is fixed with a hook beam, The upper end of the rod passes through the middle hole of the hook beam and is screwed together with the hook nut in the connecting arm. A thrust bearing is sleeved between the boom and the hook beam, and a movable pulley is arra...

AI Technical Summary

Problems solved by technology

However, when the hanging beam is hoisted, the overall force of the hanging beam is large, and the structure is complicated, and the cooperation of multiple pairs of pulley blocks is required, which is not only troublesome to manufacture, but also high in cost, so its structure still needs to be improved.
