The specific embodiment
Shown in Fig. 1～5, cable stretching device of the present invention comprises cable 6, is installed on electric up-down bar 8 and electric block 2 on the implement, wherein,
Said electric up-down bar 8 is installed on the implement through a fixed support 7, and its top is connected with cursor 11 through steering bearing 9, and said cursor 11 is provided with 2 pulleys 10, lays respectively at the two ends of cursor 11;
Be installed with cutting ferrule 15 on the outer wall of said cable 6, the equal in length of the height of said cutting ferrule 15 and cable 6, its center line is parallel with cable 6, and the internal orifice shape of said cutting ferrule 15 matches with steel cable 1 profile, and is as shown in Figure 2;
Under electronic elevating lever 8 installation sites on the fixed support 7, be fixed with an engaging device 14; Said engaging device 14 has the first vertical groove 16 that a power supply cable 6 passes through and power supply and moves second vertical groove 17 that the steel cable 1 of cucurbit 2 passes through; First vertical groove 16 wherein is made up of cable groove 16-1 and cutting ferrule groove 16-2, and said cable groove 16-1 and cutting ferrule groove 16-2 are interconnected; On the upper surface of engaging device 14, the cutting ferrule groove 16-2 of described second vertical groove 17 and composition first vertical groove 16 overlaps and is provided with, and on the lower surface of engaging device 14, described second vertical groove 17 and first vertical groove 16 are separated setting; Fig. 3, Fig. 4 and Fig. 5 are respectively vertical view, upward view and vertical cut-away view of engaging device 14;
The installation site of said electric block 2 is positioned at the below of elevating lever; It is installed on the implement through a spring support 3; This spring support 3 comprises a steel axle 3-1 and two page or leaf sheets that are hinged with this steel axle 3-1; The page or leaf sheet 3-2 that goes up that described electric block 2 is installed on the top goes up the end away from steel axle 3-1, and the nextpage sheet 3-3 of below is fixed on the implement; On nextpage sheet 3-3 than electric block 2 apart from being provided with a touch switch 3-5 outside the farther position of steel axle 3-1; Be with a spring 3-4 on this touch switch 3-5; The drift of this spring 3-4 is less than the diameter of steel axle 3-1, and the maximum working load of this spring 3-4 is slightly smaller than the weight of electric block 2 simultaneously.The steel cable 1 of electric block 2 gets into engaging device 14 by second vertical groove 17 inlets on engaging device 14 lower surfaces; Pass by vertical groove 17 outlets in second on its upper surface through engaging device 14, get into electric up-down bar 8 and be fixed on the actionless iron prop 12 in a relative ground through behind the pulley 10;
One end of cable 6 is connected with external power source 13; The other end gets in first vertical groove 16 on the engaging device 14 through steel cable fixed point, pulley 10 and electric up-down bar 8 backs along steel cable 1 trend successively; Wherein cable 6 gets into cable 6 groove 16-1; Cutting ferrule 15 gets among the cutting ferrule groove 16-2; Cable 6 is connected in electrical power control cabinet 5 after from engaging device 14, stretching out, and the power line 4 of said electric up-down bar 8 and electric block 2 is connected to electrical power control cabinet 5, and the output of said electrical power control cabinet 5 is connected with the parts of needs power supply in the implement; In cable 6 and steel cable 1 equitant part, in the cutting ferrule 15 of described steel cable 1 swelling on cable 6 outer walls.
When above-mentioned each parts install; Whole stretching device is in an original state; At this moment the steel cable between steel cable fixed point and electric up-down bar 81 should be straightened with cable 6, and the touch switch 3-5 that goes up on page or leaf sheet 3-2 and the nextpage sheet 3-3 at electric block 2 places is discontiguous.Because steel cable 1 is in the cutting ferrule 15 of swelling on cable 6 outer walls,, electric block 2 just can drive the contraction of cable 6 like this when shrinking steel cable 1 in the lump.
In order to make cable 6 more flexible through pulley 10 time, the cable 6 described in this embodiment is the flat cable of profile 6, and promptly flat cable 6.
Described implement can be miscellaneous equipments such as excavator or loader.During concrete the installation, described electric up-down bar 8 can be installed on the chassis of excavator or loader with electric block 2, and electrical power control cabinet 5 can be installed in operating room.
After equipment installed, the electric power that implement can use cable 6 to carry carried out operation as power.In the operation process, when steel cable between fixed point and electric up-down bar 81 and cable 6 ropes were long, electric block 2 was not owing to be in the state that steel cable 1 is stretching; Thereby will inevitably pressed downward owing to the reason of himself gravity, can contact with spring 3-4 in the process that presses down, when the reduction length of spring 3-4 during less than the height of touch switch 3-5; Touch switch 3-5 on the nextpage sheet 3-3 promptly is touched; Electric block 2 is opened automatically, and the steel cable 1 of electric block 2 is straightened, because steel cable 1 is in the cutting ferrule 15 of swelling on cable 6 outer walls; Being equivalent to steel cable 1 links together with cable 6; Therefore, when steel cable 1 is straightened, cable 6 also be straightened (being that long cable 6 is retracted).When steel cable 1 and cable 6 by after all stretching, electric block 2 can be along with the pulling force up lifting automatically of steel cable 1, in the process of lifting on a page or leaf sheet 3-2 leave the spring 3-4 on the nextpage sheet 3-3 gradually, thereby break off being connected of electric block 2 and power supply.
When electric block 2 was directly installed on the implement, device according to the invention still can be realized technical problem to be solved by this invention, just need manually boot the power supply of electric block 2.
