Abstract
The invention provides a lamp lift. The lamp lift is characterized by comprising a cylindrical shell with a hook, a power winding part, a lamp connecting part, lifting pulleys, a locating wheel, a power socket and steel wire lifting ropes, the power winding part comprises a motor and a motor control circuit, and the number of the steel wire lifting ropes is two. The lamp lift has the beneficial effects that safety is increased, the circuit is effectively protected, and high practicality is achieved.
Description
Technical field
The present invention relates to field of light fittings, particularly a kind of lamp lifting machine.
Background technology
Along with improving constantly of living standard, market there is various light fixture in the develop rapidly of science and technology.There is liftable light fixture in the occasions such as some large-scale stages, this light fixture is in the market all hang down to separately, and elevating function is furnished with special elevating control cab and carries out control operation, and relatively more painstaking when installing, and needs adjustment level.Use limitation underaction.
Summary of the invention
In order to overcome the defect of prior art, the invention provides following technical scheme:
A kind of lamp lifting machine, comprises the cylinder blanket with hook, power retracting part, light fixture coupling part, lifting pulley, locating wheel, supply socket and steel wire halliard, described power retracting part comprises motor and circuit for controlling motor, and described steel wire halliard is two.
Further, described motor adopts turbo-dynamo speed change integrated electric motor.
Further, described circuit for controlling motor comprises gauge tap, driving power, relay, and relay is connected with described motor, is provided with upper limit position switch, lower position switch and fault cut-offing protecting switch between described relay and motor.
Further, the external installation remote-receiver of described shell.
The beneficial effect that the present invention brings is: increase security, available protecting circuit, practicality is high.
Accompanying drawing explanation
Fig. 1 is part schematic diagram of the present invention;
Fig. 2 is stereoscopic schematic diagram of the present invention;
Fig. 3 is that motor circuit of the present invention controls schematic diagram.
Number in the figure:
1, shell; 2, steel wire halliard; 3, remote-receiver; 4, link up with; 5, light fixture coupling part; 6, supply socket, 10, relay; 11, power retracting part; 12, lifting pulley; 13, locating wheel.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
See Fig. 1 to Fig. 3, a kind of lamp lifting machine, comprise the cylinder blanket 1 with hook 4, can effectively prevent because beam wind causes electrical power contacts bad, even safety problem; Power retracting part 11; Light fixture coupling part 5; Lifting pulley 12; Locating wheel 13; Supply socket 6 and steel wire halliard 2.Described power retracting part 11 comprises motor and circuit for controlling motor, and described steel wire halliard 2 is two, not only can ensure that light fixture normally uses pulling force safety, and light fixture is raised to after top dead center and can accurately locates, and can not rotate or have the deviation of directivity.Motor adopts turbo-dynamo speed change integrated electric motor not only working stability, can easily realize take-up pulley self-locking, light fixture can be controlled at arbitrary height.
See Fig. 3, circuit for controlling motor comprises gauge tap, driving power, relay 10, and relay 10 is connected with described motor, is provided with upper limit position switch K1 between described relay and motor, effectively can prevent the excessive damage of light fixture rising impulsive force; Lower position switch K2, can after steel wire halliard 2 discharges automatic cut-off motor power supply, can prevent take-up pulley from reversing; Fault cut-offing protecting switch K3.
The external installation remote-receiver 3 of shell 1, changes flexibly easy to use.
The above; be only the specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by the present invention; the change can expected without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
