The specific embodiment
As shown in Fig. 1～5, cable stretching device of the present invention comprises cable 6, is installed on electric lifting rod 8 and electric block 2 on implement, wherein,
Described electric lifting rod 8 is installed on implement by a fixed support 7, and its top is connected with cursor 11 by steering bearing 9, is provided with 2 pulleys 10 on described cursor 11, lays respectively at the two ends of cursor 11;
Be installed with cutting ferrule 15 on the outer wall of described cable 6, the height of described cutting ferrule 15 and cable 6 equal in length, its center line is parallel with cable 6, and the interior mouth-shaped of described cutting ferrule 15 matches with steel cable 1 profile, as shown in Figure 2;
Be fixed with an engaging device 14 under electric lifting rod 8 installation sites on fixed support 7, described engaging device 14 has second vertical groove 17 that the steel cable 1 of the power supply first vertical groove 16 that passes through of cable 6 and the electronic cucurbit 2 of confession passes through, first vertical groove 16 wherein is comprised of cable groove 16-1 and cutting ferrule groove 16-2, and described 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 arranges, 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 top view, upward view and vertical cut-away view of engaging device 14;
The installation site of described electric block 2 is positioned at the below of elevating lever, it is arranged on implement by a spring support 3, this spring support 3 comprises a steel axle 3-1 and two hinges that are hinged with this steel axle 3-1, described electric block 2 is installed on the upper end away from steel axle 3-1 of upper hinge 3-2 of top, and the lower hinge 3-3 of below is fixed on implement; Be provided with a touch switch 3-5 than outside electric block 2 distance steel axle 3-1 farther position on lower hinge 3-3, the upper cover of this touch switch 3-5 has a spring 3-4, 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 is entered by second vertical groove 17 entrances on engaging device 14 lower surfaces and engages device 14, passed by vertical groove 17 outlets in second on its upper surface through engaging device 14, enter electric lifting rod 8 and be fixed on an actionless iron prop 12 in relative ground through after pulley 10;
One end of cable 6 is connected with external power source 13, the other end enters in the first vertical groove 16 that engages on device 14 after steel cable 1 trend process steel cable fixed point, pulley 10 and electric lifting rod 8 successively, wherein cable 6 enters cable 6 groove 16-1, cutting ferrule 15 enters in cutting ferrule groove 16-2, cable 6 is connected in electrical power control cabinet 5 after stretching out from engaging device 14, the power line 4 of described electric lifting rod 8 and electric block 2 is connected to electrical power control cabinet 5, and the parts that need to power in the output of described electrical power control cabinet 5 and implement are connected; In cable 6 and the equitant part of steel cable 1, 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 lifting rod 81 should be straightened with cable 6, and the upper hinge 3-2 at electric block 2 places and the touch switch 3-5 on lower hinge 3-3 are discontiguous.Because steel cable 1 is in the cutting ferrule 15 of swelling on cable 6 outer walls, when shrinking steel cable 1, electric block 2 just can drive in the lump the contraction of cable 6 like this.
In order to make cable 6 more flexible by pulley 10 time, the cable 6 described in present embodiment is the flat cable of profile 6, and namely flat cable 6.
Described implement can be the miscellaneous equipments such as excavator or loader.During concrete the installation, described electric lifting rod 8 and electric block 2 can be arranged on the chassis of excavator or loader, and electrical power control cabinet 5 can be arranged on operating room.
After equipment installed, the electric power that implement can be carried with cable 6 was that power carries out operation.in operation process, when the steel cable 1 between fixed point and electric lifting rod 8 and cable 6 ropes when long, electric block 2 is owing to not being in the state that steel cable 1 is stretching, thereby because the reason of himself gravity will inevitably be toward pressing down, 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 lower hinge 3-3 namely is touched, electric block 2 is opened automatically, 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, be equivalent to steel cable 1 and cable 6 links together, therefore, when steel cable 1 is straightened, cable 6 also be straightened (being that long cable 6 is retracted).By after all stretching, electric block 2 can be along with the pulling force up lifting automatically of steel cable 1 when steel cable 1 and cable 6, in the process of lifting on hinge 3-2 leave gradually spring 3-4 on lower hinge 3-3, thereby disconnect being connected of electric block 2 and power supply.
When electric block 2 was directly installed on implement, device of the present invention still can be realized technical problem to be solved by this invention, just need to manually boot the power supply of electric block 2.
