Abstract
The utility model relates to a projection lamp, in particular to an electric lifting projection lamp, and belongs to the technical field of power equipment. The electric lifting projection lamp comprises an outer shell. Two parallel balancing bars are fixed inside the outer shell, a projection lamp body is connected between the two balancing bars together in a sliding mode, and rotating shafts are arranged at the tail ends of the two balancing bars. A control panel is arranged at the bottom inside the outer shell, and the control panel is provided with an air switch, a direction switch and a lamp switch. The direction switch is electrically connected with a slowdown motor, the output end of the slowdown motor is connected with a gear, and the gear is provided with a gear shaft. The gear shaft is connected with a lifting rope, the lifting rope is connected with the projection lamp body and then winds across the rotating shafts, and finally the lifting rope is connected with balancing blocks. A circuit outer shell is arranged outside a lamp wire, and the lamp wire is covered with the circuit outer shell. According to the electric lifting projection lamp, the circuit outer shell is arranged outside the lamp wire, the lamp wire can be prevented from being wound in the lifting process of the lamp through the circuit outer shell, and thus safety potential risks are eliminated; the projection lamp can be replaced conveniently, and working efficiency is improved.
Description
Technical field
The utility model relates to a kind of Projecting Lamp, and Projecting Lamp that specifically can electric up-down, belongs to electrical equipment technical field.
Background technology
Along with the development of power construction, the newly-built 110kV transformer station overwhelming majority is complete indoor at present, and main transformer indoor illumination fixedly mounts on the wall.When transforming plant main transformer light fixture is damaged, because transforming plant main transformer maintenance has safe distance cannot carry out easily light fixture replacing; Meanwhile, transforming plant main transformer need to work long hours, and can not have a power failure at any time and carry out light fixture replacing.
In prior art, generally wait until after main transformer has a power failure and keep in repair, its time interval is long, cannot meet need of work.Meanwhile, traditional jacking system has two defects below: 1 motor, above product, is unfavorable for maintenance; The lifting of 2 light fixtures drives the lifting of electrical wire of lamp, and electrical wire of lamp will expose, and is also easily wound around, and causes potential safety hazard.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of electric up-down Projecting Lamp is provided, and can conveniently carry out the replacing of Projecting Lamp, has improved operating efficiency; Avoid electrical wire of lamp to be wound around when lifting, improved security.
The technical scheme providing according to the utility model, electric up-down Projecting Lamp comprises shell, it is characterized in that: in shell, fix two balancing poles parallel to each other, the floodlight that is jointly slidably connected between two balancing poles, the end of two balancing poles is provided with rotating shaft; Shell inner bottom part is provided with control panel, and control panel is provided with air switch, direction switch and lamp switch, and lamp switch is by light fixture connection floodlight; Direction switch is electrically connected to reducing motor, and the output of reducing motor connects gear, and gear is provided with gear shaft, connects lifting rope on gear shaft, walks around rotating shaft and finally connect balance weight after lifting rope connection floodlight.
Further, rotating shaft place is provided with travel switch, by travel switch, controls reducing motor stop motion.
Further, described light fixture circuit peripheral hardware has circuit shell, in circuit shell is coated on light fixture circuit.
Compared with the prior art the utility model has the following advantages:
The utility model is simple in structure, compact, rationally, electrical wire of lamp peripheral hardware has circuit shell, by circuit shell, prevents that light fixture circuit is wound around when the light fixture lifting, has eliminated potential safety hazard; Can conveniently carry out the replacing of Projecting Lamp, improve operating efficiency.

Description of reference numerals: 1-air switch, 2-direction switch, 3-lamp switch, 4-reducing motor, 5-gear, 6-gear shaft, 7-lifting rope, 8-floodlight, 9-travel switch, 10-balancing pole, 11-balance weight, 12-shell, 13-rotating shaft.
the specific embodiment
The utility model is further described in connection with the embodiment in accompanying drawing below:
As shown in Figure 1, the utility model mainly comprises shell 12, and the end that shell 12 is interior fixes 8, two balancing poles 10 of floodlight that are jointly slidably connected between 10, two balancing poles 10 of two balancing poles parallel to each other is provided with rotating shaft 13.
Shell 12 inner bottom parts are provided with control panel, and control panel is provided with air switch 1, direction switch 2 and lamp switch 3, and lamp switch 3 is by light fixture connection floodlight 8.Direction switch 2 is electrically connected to reducing motor 4, and the output of reducing motor 4 connects gear 5, and gear 5 is provided with gear shaft 6, connects lifting rope 7 on gear shaft 6, and lifting rope 7 is walked around the last balance weight 11 that connects of rotating shaft 13 after connecting floodlight 8.Direction switch 2 is controlled the work of reducing motor 4, and lamp switch 3 is controlled the work of floodlight 8, and air switch 1 prevents operating circuit short circuit.
Described rotating shaft 13 places are provided with travel switch 9, by travel switch 9, control reducing motor 4 stop motions.
Described light fixture circuit peripheral hardware has circuit shell, in circuit shell is coated on light fixture circuit, by circuit shell, prevents that light fixture circuit from the situations such as winding occurring when the light fixture lifting.
Operation principle of the present utility model is: when floodlight is damaged, by direction switch, start reducing motor, reducing motor driven gear rotates, thereby gear driven gear shaft rotates coiling lifting rope.Lifting rope pulls light fitting base to drive floodlight to decline and arrives ground, and meanwhile, balance weight 11 is pulled to eminence.After changing the floodlight damaging, reverse starting reducing motor driven gear rotates, thereby gear driven gear shaft rotates, decontrols lifting rope, and balance weight 11, because gravity factor declines, pulls floodlight to rise by lifting rope and puts in place.
