Detailed description of the invention
It should be noted that, in the situation that not conflicting, the feature in embodiment and embodiment in the present invention can combine mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the present invention in detail.
Container handling crane as shown in Figure 2, comprise the multiple cart walking mechanisms 1 that are arranged on horizontal surface, the quantity of cart walking mechanism 1 is specially four, every limit arranges two cart walking mechanisms 1, the top of one of them cart walking mechanism 1 is provided with generator set 2, generator set 2 is specially diesel powerplant, be used to cart walking mechanism 1 that power is provided, the bottom of cart walking mechanism 1 is provided with roller, mechanism 1 is played generator set 2 times by large garage, can roll being layed on ground track, each cart walking mechanism 1 is provided with the supporting leg 3 of vertically setting up, article four, supporting leg 3 tops are provided with many girders.Particularly, girder comprises girder 6 and lower girder 5, and the two ends of upper girder 6 are fixedly installed on supporting leg 3 tops, and lower girder 5 is connected with upper girder 6 by steel rope 13, and the two ends of lower girder 5 can move up and down on two supporting legs 3 therein.
In technique scheme, upper girder 6 is provided with fixed pulley group 11, lower girder 5 is provided with running block 12, particularly, fixed pulley group 11 comprises multiple fixed pulleys on girder 6 that are fixedly installed on, running block 12 comprises the multiple movable pulleys that are fixedly installed on lower girder 5 that are oppositely arranged with fixed pulley, fixed pulley is consistent with the quantity of movable pulley, certainly, its quantity also can be different, between the fixed pulley being oppositely arranged and movable pulley, be connected by steel rope 13, between fixed pulley group 11 and running block 12, be connected winding mode as shown in Figure 3.
On girder, be also provided with the gig 7 for lifting power is provided, particularly, gig 7 is fixedly installed on girder 6, and gig 7 is provided with the reel 14 for serving, while rotating gig 7, steel rope 13 can be set around on reel 14, or emit from reel 14, steel rope 13 is connected with fixed pulley group 11 and running block 12 by reel 14, particularly, steel rope 13 can first be set around on the fixed pulley of fixed pulley group 11, then is set around on the movable pulley of running block 12.It should be noted that, the canoe of steel rope 13 is multiple in addition, is not described in detail in this.
Two ends for convenience of lower girder 5 move around on supporting leg 3, also establish guide rail 4 on supporting leg 3, and the two ends of lower girder 5 are arranged on guide rail 4, guide rail 4 is specifically as follows guide groove, a guide groove is set on every supporting leg 3, and one end of lower girder 5 is arranged in guide groove, and can in guide groove, move.It should be noted that, the structure of guide rail 4 can also be other structure, as roller structure etc., specifically can, with reference to prior art or its improvement technology, be not described in detail in this.
In technique scheme, as shown in Figure 3, on lower girder 5, be also provided with the lifting appliance for lifting container 10, lifting appliance comprises suspender 9 and the first vehicle frame 8, suspender 9 bottoms are provided with the multiple connecting portions for coordinating with freight container 10, suspender 9 and the first vehicle frame 8 be arranged in parallel, and the first vehicle frame 8 is the trolley frame that those skilled in the art are commonly called as, and suspender 9 and the first vehicle frame 8 are connected by many hauling ropes 15 arranged in a crossed manner.
Further, the quantity of connecting portion is four, can be distributed on four angles of suspender 9, and when lifting container 10, four connecting portions can insert on four angles of freight container 10, and the freight container 10 of slinging.In addition,, for convenience of being connected between suspender 9 and the first vehicle frame 8, on the first vehicle frame 8 and suspender 9, be equipped with multiple point of connection.The two ends of hauling rope 15 are connected with the point of connection on the first vehicle frame 8 and suspender 9 respectively.
In technique scheme, for convenience of connecting, one end of the first vehicle frame 8 and suspender 9 is respectively equipped with two point of connection, the other end of the first vehicle frame 8 and suspender 9 is respectively equipped with two other point of connection, one end of the first vehicle frame 8 and suspender 9 is connected by two hauling ropes 15 arranged in a crossed manner, and its other end connects by the hauling rope 15 of other two intersections.The length of four hauling ropes 15 can be consistent, and the first vehicle frame 8 after connection and suspender 9 are in parastate.
Further, the shape of point of connection can be varied, do not do concrete restriction at this.In addition,, for hauling rope 15, in one embodiment, hauling rope 15 can be steel rope 13; In other embodiments, hauling rope 15 can also be chain, can also be the rope of other material or shape.
For convenience of lifting container 10, lifting appliance can be on lower girder 5 sway, particularly, lower girder 5 is provided with wing plate, the first vehicle frame 8 is arranged on wing plate, is also provided with the motor for driving the first vehicle frame 8 sway on lower girder 5, and motor can be three-in-one motor.Certainly, the first vehicle frame 8 can also be towed vehicle frame, under the effect of power, along lower girder 5 sway.
In the time that needs lift by crane freight container 10, under the effect of gig 7, steel rope 13 is slowly emitted from reel 14, and suspender 9 and the first vehicle frame 8 slowly move downwards along track under the effect of gravity, until the connecting portion of suspender 9 contacts with freight container 10, and till the freight container 10 of slinging.
The container handling crane of said structure, setting operation chamber no longer on girder, changes by operating personal and has carried out on the ground wired or wireless operation, realizes the lifting to freight container 10.
The container handling crane of said structure, tool has the following advantages:
First, alleviate the dead load of container handling crane, reduced energy consumption.The container handling crane of said structure, gig 7 is positioned on girder 6, and lifting appliance can move up and down jointly with a girder wherein, because the first vehicle frame 8 is without lifting mechanism, therefore its weight can effectively alleviate, thereby has greatly alleviated the dead load of container handling crane, has reduced energy consumption.
Secondly, lifting appliance swings little, has solved the problem to case difficulty.The container handling crane of said structure, between the first vehicle frame 8 and suspender 9, adopt hauling rope arranged in a crossed manner 15 to be connected, therefore, suspender 9 is relatively little with respect to rocking of the first vehicle frame 8, on the other hand, lower girder 5 can move in the lump with lifting appliance the top of freight container 10, then aims at, therefore, preferably resolve freight container 10 and aim at difficult problem.
Again, good operability, operating environment improves.The container handling crane of said structure, no longer setting operation chamber on girder, is operated by ground and change, specifically by terrestrial operation personnel by wired or wireless mode control lifting appliance, need not carry out aloft work.Therefore, good operability, has effectively improved the operating environment of operating personal.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
