Abstract

A marine electric crane comprises a base, and further comprises a hoisting wire rope and a variable-amplitude wire rope, wherein a tower body is mounted at the upper part of the base through a slewing bearing; a swing mechanism is mounted in the tower body and is connected with a motor; a combined winch is mounted on one side of the tower boy; a suspension arm is mounted on the other side of the tower body; a pulley is arranged at the head of the suspension arm, at the top of the tower body, and on a tackle pulley; one end of the hoisting wire rope is connected with a combined winch; the other end of the hoisting wire rope is connected onto the tackle pulley through the pulley; one end of the variable-amplitude wire rope is connected with the combined winch; the other end of the variable-amplitude wire rope is connected onto the tackle pulley through the pulley; a lifting hook for hoisting cargos is also mounted on the tackle pulley. Compared with the conventional hydraulic crane, as all actuating activities are driven through electric power, the marine electric crane further has the advantages that phenomena such as oil leak are avoided to reduce environment pollution; the reaction is fast; the operation is simple; the safety and stability are good.

Description

Marine electric hoisting crane
Technical field
The present invention relates to weight-lifting equipment technical field, especially a kind of marine electric hoisting crane.
Background technology
The fluid power system that goliath on current most of bulge carrier still adopts, hydraulic efficiency pressure system exists some defects, and manufacture craft requires high, and fluid will regularly replace, and easily causes oil leaking pollution environment etc.
Summary of the invention
The applicant, for the shortcoming in above-mentioned existing production technology, provides a kind of marine electric hoisting crane rational in infrastructure, thereby adopts driven by power, saves the energy, and security and stability is high.
The technical solution adopted in the present invention is as follows:
A marine electric hoisting crane, comprises base, and described base top is provided with tower body by pivoting support, in described tower body, swing type mechanism is installed, and described swing type mechanism is connected with motor; One side of described tower body is provided with combined winch, the opposite side of described tower body is provided with arm, the top that the head of described arm is positioned at tower body is provided with pulley, be positioned at polyspast, also comprise hoist rope, one end of described hoist rope is connected with combined winch, and the other end of described hoist rope is connected in polyspast through pulley; Also comprise variable-amplitude steel wire rope, one end of described variable-amplitude steel wire rope is connected with combined winch, and the other end of described variable-amplitude steel wire rope is connected in polyspast through pulley; Be positioned at the suspension hook that lifting cargo is also installed in polyspast.
Further improvement as technique scheme:
Described base is connected with the deck on boats and ships;
Described base is welded in the deck on boats and ships.
Beneficial effect of the present invention is as follows:
Compact conformation of the present invention, reasonable, easy to operate, the present invention passes through driven by power by all performing an action, compare with hydraulic lift in the past, avoided leakage of oil etc. situation, reduced environmental pollution, electric crane has movement response sensitive, controls simply the high feature of security and stability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein: 1, base; 2, tower body; 3, arm; 4, combined winch; 5, variable-amplitude steel wire rope; 6, hoist rope; 7, polyspast; 8, suspension hook.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, the marine electric hoisting crane of the present embodiment, comprises base 1, and base 1 top is provided with tower body 2 by pivoting support, in tower body 2, swing type mechanism is installed, and swing type mechanism is connected with motor; One side of tower body 2 is provided with combined winch 4, the opposite side of tower body 2 is provided with arm 3, the top that the head of arm 3 is positioned at tower body 2 is provided with pulley, be positioned at polyspast 7, also comprise hoist rope 6, one end of hoist rope 6 is connected with combined winch 4, and the other end of hoist rope 6 is connected in polyspast 7 through pulley; Also comprise variable-amplitude steel wire rope 5, one end of variable-amplitude steel wire rope 5 is connected with combined winch 4, and the other end of variable-amplitude steel wire rope 5 is connected in polyspast 7 through pulley; Be positioned at the suspension hook 8 that lifting cargo is also installed in polyspast 7.
Base 1 is connected with the deck on boats and ships.
Base 1 is welded in the deck on boats and ships.
Combined winch 4 of the present invention has comprised hoister winch and span winch, and space mounting position has been saved in knockdown installation.
In actual use procedure, by the knee-action that is used for controlling arm 3 of variable-amplitude steel wire rope 5.By electric machine control, be active in one's movements, safe.
More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention, referring to claim, within protection scope of the present invention, can be done any type of modification.
