Detailed Description

The following is further detailed by way of specific embodiments:

as shown in fig. 1 and 2, a balancing device of a marine crane is disposed on a hull 1, a first hoisting mechanism is disposed on the hull 1, the first hoisting mechanism includes a first mounting arm 4 and a first winch 7, and further includes a second hoisting mechanism disposed in a mirror image manner on the first hoisting mechanism, the second hoisting mechanism includes a second mounting arm 6 and a second winch 8, a hook 12 is disposed on a pull rope of each of the first winch 7 and the second winch 8, an auxiliary counterweight mechanism is disposed on the hook 12 of the second winch 8, the auxiliary counterweight mechanism includes a mounting ring 10, a plurality of lifting ropes 13 are disposed on the circumference of the mounting ring 10, one end of each of the plurality of lifting ropes 13 is fixed on the mounting ring 10, the other end of each of the plurality of lifting ropes is fixed on the hook 12 of the second winch 8, a water container 11 fixedly connected with the mounting ring 10 is disposed on the lower edge of the mounting ring 10, and it should be noted that a drain valve or a drain hole is disposed on the water container, which is considered by those skilled in the art, and will not be described herein.

For better understanding, the working principle of the utility model is as follows:

when a first hoisting mechanism arranged on a ship body 1 works, a water container 11 arranged on a second hoisting mechanism is placed into water, so that the container is submerged by water, when the first hoisting mechanism hoists a weight 5 and the ship body 1 inclines, the water container 11 is driven to move towards the water surface, most of gravity of the water container 11 acts on the second hoisting mechanism at the moment, because the first hoisting mechanism and the second crane are arranged in a mirror image mode, the water container 11 is equivalent to a counterweight, namely when the first hoisting mechanism hoists the weight 5, the moment for enabling the ship body 1 to incline is reduced, namely the inclination angle and the overturning probability of the ship body 1 are reduced.

The water container 11 is a water storage bag, the opening end of the water storage bag is fixedly connected to the outer side edge of the mounting ring 10, the fixing mode at the position can be fixed by sewing, the fixing mode can also be fixed by sleeving the fixing ring, the sewing fixing refers to the fact that the mounting ring 10 is sewn to the inner side of the edge of the water storage bag, the water storage bag is preferably made of waterproof canvas, the water storage bag has the advantages that when the water storage bag is not used, the water storage bag is conveniently folded on the ship body 1, meanwhile, the quality of the water storage bag is relatively light, the water storage bag is more convenient to place on the ship body 1, and the water storage bag can be used on the device if the design of a water storage tank and the like is adopted.

Be equipped with rotating base 2 on the hull 1, be equipped with erection column 3 on the rotating base 2, the one end of first installation arm 4 and second installation arm 6 is fixed in on the erection column 3, it should explain that, rotating base 2 is prior art, is similar to the mechanism etc. that rotates the rotatory department of chair, and the benefit that sets up rotating base 2 lies in, is convenient for place the length direction of first hoist mechanism and second hoist mechanism rotation to hull 1, is convenient for turn to the heavy object 5 of hanging and getting simultaneously and places on hull 1.

The first mounting arm 4 and the second mounting arm 6 are obliquely and upwards arranged, the end parts of the first mounting arm and the second mounting arm are higher than the hull 1 due to the oblique arrangement, the interference between the weight 5 and the hull 1 during steering is avoided, and meanwhile, the second mounting arm 6 is preferably designed to be telescopic and can be used as a counterweight of the weight 5 with larger mass in a length adjusting mode.

Be equipped with crossbeam 9 between first installation arm 4 and the second installation arm 6, crossbeam 9's both ends are fixed in respectively on first installation arm 4 and the second installation arm 6, crossbeam 9's setting is connected first installation arm 4 and second installation arm 6 as an organic wholely, make the mode more direct of its transmission atress, avoid 3 end fixing department atress of erection column great emergence fatigue damage's problem, the crossbeam here can be for the steel pipe that both ends dare to connect, the steel column etc. also can be for both ends fixed connection and the wire rope that tightens simultaneously.

The number that sets up lifting rope 13 on the collar 10 is 4, and 4 lifting rope's 13 one end circumference equipartitions and collar 10 on, the fixed mode of circumference is convenient for mention collar 10 level, makes flourishing water receptacle 11 carry out the retaining.

The hooks 12 arranged on the first winch 7 and the second winch 8 are provided with lock tongues, so that the problem that the heavy object 5 and the water container 11 fall off can be avoided.

One end of the first mounting arm 4 and the second mounting arm 6, which is far away from the ship body 1, is provided with a fixed pulley, and the pull ropes of the first winch 7 and the second winch 8 are wound on the fixed pulley. The first mounting arm 4 and the second mounting arm 6 are provided in the width direction of the hull 1, and the provision of the fixed pulley reduces the moving friction of the stay cord, and the provision in the width direction can shorten the design length of the love mounting arm and the second mounting arm 6.
