Abstract
The utility model provides a rotating lamp holder device of a locomotive head lamp. The rotating lamp holder is driven to rotate by a motor which drives a worm rod 4; a worm gear 3 is driven to rotate by the worm rod 4; a gear wheel 5 is driven to rotate by the worm gear 3; a sector gear wheel 6 is driven to rotate by the gear wheel 5; so a lamp stand 2 is driven to rotate. The rotating lamp holder device of a locomotive head lamp of the utility model is used to adjust the lighting angle in a certain range according to different cases in front of the locomotive path.
Description
Technical field:
The utility model belongs to field of mechanical technique, and it relates to a kind of rotatable mechanical device.
Background technology
At present, the lamp socket of known engine hatch lamp device is a unmodified, and it is made up of lamp bracket, lamp socket.When but locomotive moves on the bend route, and the angle of head lamp illumination can not be rotated the problem of vehicle light illumination inconvenience in the time of certainly will causing the locomotive night running in the existing engine hatch lamp device.
Summary of the invention
The purpose of this utility model provides a kind of rotatable engine hatch lamp lamp base device, adopts this device can make the light angle of locomotive head lamp adjustable in the certain angle scope.
A kind of rotatable engine hatch lamp lamp base device (as shown in Figure 1, 2, 3) that the utility model provides comprises support 1, lamp bracket 2, it is characterized in that it also comprises worm gear 3, worm screw 4, gear 5, fan type gear 6, lamp bracket rotating shaft 7, casing 8; Worm screw 4 is installed in the chamber of worm gear 3, worm gear 3 is installed on the support 1, gear 5 is installed in the axle lower end of worm gear 3, gear 5 and 6 engagements of fan type gear, fan type gear 6 is installed in lamp bracket rotating shaft 7 bottoms, lamp bracket 2 is fixed in the lamp bracket rotating shaft 7, and the cavity of cavity of dress worm screw 4 and dress worm gear 3 is formed the cavity of casing 8 jointly, and casing 8 is fixed on the support 1.
The working process of a kind of rotatable engine hatch lamp lamp base device of the present utility model is: motor-driven worm screw 4 is rotated, and worm screw 4 drives worm gear 3 and rotates, and worm gear 3 driven gears 5 rotate, and gear 5 drives fan type gear 6 and rotates, and rotates thereby drive lamp bracket 2.So, utilize device of the present utility model, just can control lamp bracket 2 by motor and rotate.Motor positive and inverse drives the rotating of worm screw 4, the rotating of worm screw 4 drives the cw and the anticlockwise motion of worm gear 3, coaxial and be fixed as one because of gear 5 and worm gear 4, the rotation of worm gear 3 and then driven gear 5 cws and anticlockwise motion, the rotation of gear 5 drives the rotation of fan type gear 6, the rotation of fan type gear 6 drives lamp bracket rotating shaft 7 and rotates, and then realizes that lamp bracket 2 rotates.Thereby realize the adjustment of light angle according to actual needs with the rotating of locomotive operation route conditions control motor.
Need to prove:
1) lamp socket plays the supporting role of illumination equipment, and the mounting hole of its mounting hole and former head lamp is identical, and the bearing that supports lamp bracket is installed on the support with the device that supports worm gear 3, worm screw 4.
2) gear 5 plays the mechanical drive effect with fan type gear 6, and fan type gear 6 is installed in the lower end of lamp bracket rotating shaft 7, and gear 5 is installed in the lower end of worm gear 3, and gear 5 is positioned on the plane with fan type gear 6.
The beneficial effects of the utility model are
The rotatable engine hatch lamp lamp base device that adopts the utility model to provide makes the light angle of engine hatch lamp adjustable in the certain angle scope.It has overcome existing locomotive head lamp can not carry out the adjustable shortcoming of light angle according to the different situation of locomotive the place ahead route.
