Detailed description of the invention
The invention will be further described for the embodiment being arranged on excavator swing arm below in conjunction with accompanying drawing and the present invention.
As depicted in figs. 1 and 2, the present embodiment includes headlight 1, DC source 2, double-point double-throw switch 3, turns to electric magnet 4, guide pad 5, push rod 6, connecting rod 7, rocking bar 8, arc chute seat 9, arc chute pin 10 and rocking bar core 20, DC source 2 is connected with turning to electric magnet 4 by double-point double-throw switch 3, electromagnet armature 43 is turned to be connected with push rod 6 left end, push rod 6 midfoot support, in guide pad 5, is slidably matched with guide pad 5. Push rod 6 right-hand member is hinged with connecting rod 7 left end, hinged in the middle part of connecting rod 7 right-hand member and rocking bar 8, and rocking bar 8 left end is hinged with rocking bar core 20, and rocking bar 8 right-hand member is hinged by arc chute pin 10 and arc chute seat 9. Arc chute seat 9 and rocking bar core 20 are the steel plate bending part of intermediate projections, and guide pad 5, rocking bar core 20 two ends and arc chute seat 9 two ends are weldingly fixed on engineering machinery swing arm 30 side. Double-point double-throw switch 3 is arranged on the control panel place of driver's cabin, facilitates operator. Drawing two wires respectively from DC source 2 both positive and negative polarity to illustrate connection shown in Fig. 1 and receive two, the centre binding post of double-point double-throw switch 3, all the other 4 binding posts turn to the first end 41 (a end) of electric magnet 4 and the second end 42 (b end) by being coupled with after the one group of parallel connection of two diametrical connection terminals.
As shown in Figure 4, push rod detent mechanism 40 is arranged on and turns between electromagnet armature 43 and guide pad 5, including multiple rows of location teeth groove 61 that positioning electromagnet 401, location bar 402 and push rod 6 side are arranged, positioning electromagnet 401 is vertically set on the downside of multiple rows of location teeth groove 61, bar 402 lower end is vertical is connected with location for positioning electromagnet armature 411, in the middle part of the bar 402 of location, boss is supported on positioning electromagnet shell 405 by stage clip 403, and bar 402 upper end, location is embedded in the teeth groove 61 of location. DC source 2 both positive and negative polarity is connected with positioning electromagnet 401 two ends respectively by and off switch 404, and on and off switch 404 (S) is also mounted at control panel place in the driver's cabin being easy to operation.
Rocking bar 8 right-hand member is provided with kidney-shaped elongated slot 81, and arc chute seat 9 is provided with arc chute 91, it is simple to arc chute pin 10 drives rocking bar 8 to swing, and fixes bar and be fixed on rocking bar 8 through the rocking bar fixing hole 82 near rocking bar core 20 one end bottom headlight 1. It is 0��40 �� that rocking bar 8 carries headlight 1 around the pendulum angle �� at the hinged center of rocking bar 8 left end, and the present embodiment is 37 ��, and headlight 1 can regulate within the scope of 0��37 ��, it is simple to excavator night work.
As shown in Figure 4, the longitudinal profile of arc chute pin 10 is " I-shaped ", including top cover 101 and shank 102, described shank 102 mediad vertically extends cervical region 103, described cervical region 103 is vertically upward through arc chute 91 and kidney-shaped elongated slot 81, and cervical region 103 top and top cover 104 are riveted. It is easy to the swing of rocking bar 8, it is prevented that arc chute pin 10 comes off.
When needs adjust headlight 1 direction, first Guan Bi on and off switch 404 (S), positioning electromagnet 401 obtains electric generation magnetic field, and positioning electromagnet armature 411 drives location bar 402 to overcome stage clip elastic force downward, bar 32 upper end, location departs from location teeth groove 61, and push rod 6 unlocks and can move left and right.Then double-point double-throw switch 3 is made to connect to the left, the first end 41 (a end) turning to electric magnet 4 connects DC source 2 positive pole, second end 42 (b end) connects DC source 2 negative pole, DC source 2, double-point double-throw switch 3 and turn to electromagnet armature 41 to constitute forward loop, electric magnet 4 is turned to produce forward magnetic field, promote push rod 6 to move to right, promote rocking bar 8 to rotate clockwise under the guiding at arc chute 91 by push rod 6, connecting rod 7, it is achieved that headlight 1 turns to clockwise.
The operating process that headlight 1 turns to counterclockwise is essentially identical with said process, institute the difference is that: double-point double-throw switch 3 connects to the right, the first end 41 (a end) turning to electric magnet 4 connects DC source 2 negative pole, second end 42 (b end) connects DC source 2 positive pole, DC source 2, double-point double-throw switch 3 and turn to electromagnet armature 41 to constitute negative sense loop, electric magnet 4 is turned to produce opposing magnetic field, push rod 6 is pulled to move to left, rocking bar 8 is promoted to rotate counterclockwise under the guiding of arc chute 91 by push rod 6, connecting rod 7, it is achieved that headlight 1 turns to counterclockwise.
Complete after headlight 1 turns to, by double-point double-throw switch 3 in centre position, on and off switch 404 (S) disconnects, and now location bar 402 upwards moves under the effect of stage clip reset force, embedding location, bar 32 upper end, location teeth groove 61 locks push rod 6 so that it is can not move left and right.
The present embodiment can make headlight 1 swing within the scope of 0��37 ��, has widened the illumination visual field of nighttime driving person, meets excavator night work demand.
In addition to the implementation, the present invention can also have other embodiments, all employings to be equal to replacement or the technical scheme of equivalent transformation formation, all falls within the protection domain of application claims.
