Abstract
The utility model relates to a structural improvement of an electric lifting illuminating electric appliance, which belongs to the technical field of illuminating electric appliances. The product comprises a power supply contact structure and a hoisting device which are arranged on a bottom base, the improvement is that a rotating axle of the hoisting device of the bottom base is vertically arranged and at least the lower end is provided with a thread. The position of the bottom base corresponding to the lower end of the rotating axle is provided with a through hole, the illuminating electric appliance is fixed with a vertical safety rod and the upper end of the safety rod is provided with a thread matched with the lower end of the rotating axle. Thus, when the illuminating electric appliance rises to the position close to upper limit, the rotation of the rotating axle of the hoisting device enables the thread of the lower end to be screwed with the thread of the upper end of the safety rod. Thus, in the positioning work process of the illuminating electric appliance, even an accident occurs and a hoisting suspension rope is disconnected, the illuminating electric appliance still can not automatically fall off by the screwing lock function of the thread of the safety rod in order to guarantee safety.
Description
Technical field
The utility model relates to a kind of liftable electric lighting, relates in particular to a kind of architecture advances of electrodynamic type liftable electric lighting, belongs to the electric lighting technical field.
Background technology
No matter common electric lighting is suspension type or ceiling type at present, and the position is fixing all the time, and the operation of need climbing to a higher point when therefore maintenance, cleaning is very dangerous, also has the danger of electric shock simultaneously when carrying out above-mentioned operation.When carrying out the maintenance operation of street lamp, also can block traffic.
In order to address the above problem, people have invented the electric lighting with lowering or hoisting gear, wherein have dependence manual, also have motor-driven.Its basic structure is: the base that the electric lighting position is installed is provided with the power supply contact structures, and is mounted with winding plant, and the end that dangles of elevator hoist cable is connected with electric lighting.Like this, when the winding plant rolling-in, electric lighting hangs the installation site of eminence, contacts with electric contact structure, can normal illumination; When the winding plant pine oil, electric lighting falls, and breaks away from electric contact structure, can keep in repair easily, clear up.For example, the disclosed lift lighting device of Chinese patent that application number is 00243757.0, the applying date is 2000.07.21 promptly has above function.
Yet, understand according to applicant, existing this series products has does not have insurance institution, though what have has an insurance institution, but complex structure, use difficulty, so this series products can't reach safety effect in the middle of practical application, for this reason when the elevator hoist cable because of wearing and tearing or when meeting other fortuitous events disconnections, electric lighting will drop suddenly, produces hardly imaginable consequence.
The utility model content
The purpose of this utility model is: at the potential safety hazard that above prior art exists, proposes in the course of the work a kind of, even run into accident, the disconnection of elevator hoist cable, the electrodynamic type liftable electric lighting that also can not drop voluntarily.
In order to reach above purpose, electrodynamic type liftable electric lighting of the present utility model comprises power supply contact structures and the winding plant that is placed on the base, the end that dangles of described winding plant hoist cable is connected with electric lighting, described electric lighting is provided with the electrical contact corresponding with the power supply contact structures, its improvements are: the rotating shaft of described base winding plant is vertically installed, at least the lower end is shaped on screw thread, the position of the corresponding described rotating shaft of described base lower end has through hole, be fixed with vertical bumper bar on the described electric lighting, the upper end at least of described bumper bar is shaped on the screw thread that matches with described rotating shaft lower end.
Like this, when electric lighting under the drive of winding plant hoist cable, when being raised near the limes superiors position, the rotation of winding plant rotating shaft will make the screw thread of the screw thread of its lower end and bumper bar upper end screw.Therefore, in the electric lighting course of work in place, even run into accident, the elevator hoist cable disconnects, and owing to the locking action that screws of bumper bar screw thread, electric lighting can not drop voluntarily, thereby guarantees safety.Keep in repair when needs fall electric lighting, when clearing up, the rotating shaft of winding plant counter-rotating breaks away from the bumper bar screw thread automatically and screws state, thereby electric lighting is broken away from by the lock state, can be unfettered, decline freely.
This shows that the utility model has been eliminated the potential safety hazard that prior art exists with the architecture advances of advantages of simple, has guaranteed its security and reliability.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of an embodiment of the utility model.
The specific embodiment
Embodiment one
The electrodynamic type liftable electric lighting of present embodiment as shown in Figure 1, base 1 lower surface is equipped with the contact chip that is connected with power supply, the elevator rotating shaft 3 on support 2 of the output worm screw 9 that the winding plant of upper surface is driven by decelerator 8 by motor 7, positioned vertical, with the rotating shaft 3 coaxial worm gears that are connected 4, worm gear 4 meshes with worm screw 9.Elevator rotating shaft 3 is one to be shaped on the hollow shaft of internal thread, and the position of base 1 corresponding rotating shaft 3 lower ends has through hole.The hoist cable that twines in the rotating shaft 3 is drawn downwards through assembly pulley 6, dangles to hold the adapter 13 with on the electric lighting to be connected a pair of pulley 14 that adapter 13 is provided with the electrical contact corresponding with power contacting plate 16 and passes through hoist cable.Be fixed with vertical bumper bar 11 on the adapter 13 of electric lighting, this bumper bar is shaped on the external screw thread that matches with rotating shaft 3.
Therefore, when elevator motor 7 drives rotating shaft 3 rotations, make lighting 15 by adapter 13, when under the drive of hoist cable 12, being raised near the limes superiors position, the screwed hole of rotating shaft 3 screws with the screw thread of bumper bar 11 upper ends gradually, and contact chip is contacted with electrical contact 16.After this, even run into accident, elevator hoist cable 12 disconnects, because the bumper bar screw thread is in and screws lock-out state, so light fixture can not drop, can guarantee safety.Keep in repair when needs fall lighting, when clearing up, the rotating shaft of winding plant 3 counter-rotatings break away from bumper bar 11 screw threads automatically and screw state, thereby lighting is broken away from by the lock state, can be unfettered, decline freely.
In addition, also be shaped on two positioning and guiding bars 10 of band guide cone upwards on adapter 13, the position of base plate 1 corresponding two positioning and guiding bars is shaped on two locating holes 5, therefore can be when rising lighting 15 by adapter 13, play guiding function, guarantee that electrical contact 16 and bumper bar 11 are accurately in place.
The electrodynamic type liftable electric lighting that experiment showed, present embodiment is not only safe but also reliable.
In addition to the implementation, the utility model can also have other embodiments.For example, the rotating shaft lower end can be external screw thread, and the upper end of bumper bar is an internal thread, or the like.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
