Abstract
The utility model relates to an overhead beacon which solves the problem of the contact reliability of a power supply. A windproof lifting beacon comprises a beacon body, a staircase, a lift driving mechanism, a counterweight, a lifting lamp frame, a pulley box, a distribution box, a supporting seat, a lamp and a power contact mechanism, wherein, the power contact mechanism is composed of a static contact mechanism and a moving contact mechanism. The utility model is characterized in that the static contact mechanism is fixed to the top of the beacon body; the moving contact mechanism is fixed on the lifting lamp frame; the static contact of the static contact mechanism is provided with a lower concave part; the moving contact of the moving contact mechanism is provided with an upper convex part matched with the lower concave part; the utility model is used for lighting for transportation.
Description
The utility model relates to the lift beacon, refers in particular to a kind of windproof lift projection lighthouse.
Mostly the beacon of existing various fixedly light fixtures is that light fixture uphangs, and is difficult to ascend a height, and especially in ice and snow and wind and rain sky, maintenance activity is difficult and dangerous more, has influenced the on-call maintenance and the operate as normal of lighting apparatus.Though the high bar of lift has solved the difficulty of light fixture maintenance, but body of the tower is welded by large diameter steel pipe, the long part of body is heavy, see comparatively difficulty of an installation, and the wind resistance of most of lifting lamp bracket is poor, cause lighting cisco unity malfunction under powerful wind-force, usually come in contact switch sparking and accident such as burn, thereby be difficult to apply.
It is a kind of simple in structure, safe and reliable that the purpose of this utility model is to provide, the lift projection lighthouse that wind resistance is good.
The purpose of this utility model is achieved in that wind proof lift projection lighthouse, comprises body of the tower, staircase, lift drive mechanism, counterweight, lifting lamp bracket, pulley casing, distribution box, bearing, light fixture and power contact head mechanism; Power contact head mechanism is made up of static contact mechanism and dynamic contact mechanism; It is characterized in that: static contact mechanism is fixed on the top of body of the tower, and dynamic contact mechanism is fixed on the lifting lamp bracket; The static contact of static contact mechanism is provided with lower concave part, and the moving contact of dynamic contact mechanism is provided with the upper convex portion that matches with lower concave part.
Above-mentioned design, the contact-making surface that upper convex portion and lower concave part match also can be the hemisphere face or the conical surface or other shapes for circle dimension shape face.The break-make of beacon power supply, promptly the upper convex portion of the lower concave part by static contact and moving contact closed or separate realized, obviously circle dimension shape face contact, closure is reasonable, effectively wind resistance is safe and reliable.
Describe concrete structure of the present utility model and effect below in conjunction with Figure of description in detail with embodiment.
Fig. 1 is the utility model total structure schematic diagram.
Fig. 2 is the utility model power contact head structural scheme of mechanism.
As shown in Figure 1, 2: the utility model mainly is made of bearing 9, body of the tower 1, staircase 2, distribution box 8, pulley casing 6, lifting lamp bracket 5, light fixture 10, lift drive mechanism 3, counterweight 4, staircase 2 and power contact head mechanism 7.Power contact head mechanism 7 is made up of static contact mechanism 20 and dynamic contact mechanism 21, and static contact mechanism 20 comprises seat board 11, static contact 14, insulation sleeve 18, rain cover 19; Dynamic contact mechanism 21 comprise seat board 12 ,-bedplate 13, moving contact 15, expansion link 16, compression spring 17.Static contact 14 is provided with lower concave part 22, and moving contact 15 is provided with upper convex portion 23, and both leave gap 24 after coincideing.The setting in gap 24 makes the contact contact more good.Static contact 14 is installed on the seat board 11 by bolt, nut 3 and insulation sleeve 18; Moving contact 15 is installed on the seat board 12 by bolt and nut and insulation sleeve, and seat board 12 is installed by expansion link 16 and is bound up on the bedplate 13, is with compression spring 17 on the expansion link 16.Seat board 12 and slide over expansion link 16 and with the compression spring 17 contact.Static contact mechanism 20 is connected with body of the tower 1 by seat board 11, and dynamic contact mechanism 21 is connected with lifting lamp bracket 5 by bedplate 13.By pulley casing 6 and lifting wire rope lift drive mechanism 3 and lifting lamp bracket 5, light fixture 10 are combined as a whole.When light fixture 10 needs to descend, rotate counterclockwise driving wheel 3, light fixture 10 is along with lifting lamp bracket 5 slowly descends under the effect of counterweight 4 and steel wire rope; In the time will rising light fixture 10, up time is tiltedly rotated lifting driving wheel 3, and lifting lamp bracket 5 is being with light fixture 10 upwards to rise.Lift drive mechanism 3 can be manual, also can be electronic, hydraulic pressure or pneumatic type.The break-make of beacon power supply is that the closure by static contact mechanism 20 and dynamic contact mechanism 21 realizes with separating.When lifting lamp bracket 5 rises to certain altitude, static contact mechanism 20 and dynamic contact mechanism 21 auto-closings, and more pressure is tighter under the effect of compression spring 17, even instantaneous break-make phenomenon can not take place under powerful wind-force effect yet.In addition, wind proof lifting beacon has been eliminated the long-term sparking of power contact head mechanism and phenomenon such as has frequently been burnt, thus also degree of safety of the reliability that has improved service life of power contact head and beacon.
The utility model is compared with existing beacon, and eliminated power contact head and frequently struck sparks and the phenomenon such as burn, Greatly improved the stability of under powerful wind-force, working, simple in structure, easy to operate, quick for installation, Safe and reliable, failure rate is low, the consumption steel are economized, and maintain easyly, are a kind of economical and practical Traffic lighting equipment.
