Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of crane arm rotary lighting device, can change fast rotational illuminating lamp according to boom position, thus makes light prolonged exposure to suspension hook, is convenient to work; Can regulate the spacing between two illuminating lamps in addition, comformability is good.
To achieve these goals, the technical solution adopted in the utility model is: this crane arm rotary lighting device, comprises illuminating lamp I, illuminating lamp II, actuating device and expansion link,
Described actuating device comprises housing, DC machine, worm gear, worm screw, axis expansion link and endless screw support, and DC machine, worm gear, worm screw, axis expansion link and endless screw support are placed in housing; Worm screw is contained on endless screw support, one end of worm screw is connected with DC machine, worm gear is fixed on axis expansion link, worm gear and worm mesh, one end of axis expansion link is connected with illuminating lamp I by rebound I, the other end of axis expansion link is connected with the expansion link one end be arranged on outside housing by coupling piece, and the other end of expansion link is connected with illuminating lamp II by rebound II.
Preferably, also comprise potential device and control circuit board, described potential device and control circuit board are arranged in housing, and the test side of potential device is by the gears meshing on gear and axis expansion link; Control circuit board is connected with potential device and DC machine respectively.
Further, also comprise two adapter plates, two described adapter plates are separately fixed at the other end of housing sidepiece and expansion link.
Compared with prior art, the utility model adopts worm and gear and DC machine to combine, and changing fast rotational illuminating lamp, thus make light prolonged exposure to suspension hook, being convenient to operated by personnel, without the need to driving manually according to boom position; Adopt expansion link and axis Telescopic rod structure in addition, thus can regulate the spacing between two illuminating lamps, comformability is good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to cutaway view.
In figure: 1, illuminating lamp I, 2, rebound I, 3, adapter plate, 4, worm gear, 5, coupling piece, 6, axis expansion link, 7, potential device, 8, housing, 9, expansion link, 10, rebound II, 11, illuminating lamp II, 12, control circuit board, 13, DC machine, 14, endless screw support, 15, worm screw.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2, the utility model comprises illuminating lamp I 1, illuminating lamp II 11, actuating device and expansion link 9,
Described actuating device comprises housing 8, DC machine 13, worm gear 4, worm screw 15, axis expansion link 6 and endless screw support 14, and DC machine 13, worm gear 4, worm screw 15, axis expansion link 6 and endless screw support 14 are placed in housing 8; Worm screw 15 is contained on endless screw support 14, one end of worm screw 15 is connected with DC machine 13, worm gear 4 is fixed on axis expansion link 6, worm gear 4 engages with worm screw 15, one end of axis expansion link 6 is connected with illuminating lamp I 1 by rebound I 2, the other end of axis expansion link 6 is connected with expansion link 9 one end be arranged on outside housing 8 by coupling piece 5, and the other end of expansion link 9 is connected with illuminating lamp II 11 by rebound II 10.
Above-mentioned DC machine 13 can adopt eletric button to control, also potential device 7 and control circuit board 12 can be adopted, described potential device 7 and control circuit board 12 are arranged in housing 8, and the test side of potential device 7 is by the gears meshing on gear and axis expansion link 6; Control circuit board 12 is connected with potential device 7 and DC machine 13 respectively; A kind of mode after preferred employing, this mode can realize automatically adjusting illuminating lamp according to crane arm change in location and rotate, thus makes light prolonged exposure to suspension hook.
Improve as one of the present utility model, also comprise two adapter plates 3, two described adapter plates 3 are separately fixed at the other end of housing 8 sidepiece and expansion link 9; Increase adapter plate 3, be more convenient for this device to be fixed on crane arm.
Working process: when hoisting crane starts to lift by crane, according to the signal of the crane arm change in location transmitted, control circuit board 12 controls DC machine 13 to start to rotate, DC machine 13 drives worm screw 15 to drive worm gear 4 to rotate, worm gear 4 drives axis expansion link 6 to rotate, one end of axis expansion link 6 drives illuminating lamp I 1 to rotate, and the other end drives expansion link 9 to rotate by coupling piece 5, thus drives illuminating lamp II 11 to rotate; Control circuit board 12 detects the angle of two illuminating lamps rotations in real time by potential device 7 simultaneously, and when after the angle that it reaches required, control circuit board 12 controls DC machine 13 and stops the rotation.In addition as the distance between two illuminating lamps need be regulated can be regulated by the flexible of expansion link 9.
