A kind of multi-functional lighting lifting device

Abstract

The invention discloses a novel multifunctional lamp lifting device. The device comprises a box, a take-up rotation disc and a rolling power mechanism are arranged in the box, and the rolling power mechanism comprises a rotation shaft and a bearing assembly; the bearing assembly comprises a main bearing and a sub bearing, the main bearing and the sub bearing sleeve the rotation shaft, and a rotation assembly is connected to the main bearing and comprises a reading dial and a synchronizing wheel; the reading dial, the synchronizing wheel and the main bearing are connected with one another. Thesub bearing is provided with the take-up rotation disc, and the take-up rotation disc is connected with the main bearing or the rotation assembly; the rolling power mechanism further comprises a driving device for driving the rotation assembly to rotate; the device further comprises a brake mechanism, and the brake mechanism comprises a counting optical coupler for monitoring the reading dial anda brake device for limiting rotation of the reading dial. The novel multifunctional lamp lifting device achieves a real sense of dual-bearing coaxial rotation effect and is ingenious and reasonable instructural design, the phenomenon can be effectively avoided that the take-up rotation disc deviates or is out of balance during rotation, and the use safety performance of the lamp lifting device isalso greatly improved.

Description

technical field [0001] The invention relates to a lifting device, in particular to a multifunctional lamp lifting device. Background technique [0002] In order to obtain a specific lighting effect, some lamps used in the prior art have a lifting function, and the lifting device can realize the lifting movement of the lamp during use, thereby producing a specific stage lighting effect. [0003] At present, the internal structure design of the lamp lifting device on the market is very unreasonable. For example, in the prior art, the detection device, the solenoid valve and the reading plate in the lamp lifting device are separately installed, that is, the reading plate is set on the motor shaft, which only plays a role. Reading function, once the belt on the motor is broken, the detection device still cannot detect it, because the reading plate is set on the motor shaft, and the solenoid valve will not pop out at this time, so there will be a danger of the lamp falling; [0...

Problems solved by technology

[0003] At present, the internal structure design of the lamp lifting device on the market is very unreasonable. For example, in the prior art, the detection device, the solenoid valve and the reading plate in the lamp lifting device are separately installed, that is, the reading plate is set on the motor shaft, which only plays a role. Reading function, once the belt on the motor is broken, the detection device still cannot detect it, because the reading plate is set on the motor shaft, and the solenoid valve will not pop out at this time, so there will be a danger of the lamp falling;

[0004] In addition, in the lighting lifting device of the prior art, the take-up turntable is basically two rotating disks that are separated and fixed on different positions by screws through two rotating shafts to form a take-up turntable; as described in claim 6 of patent number CN201520301038.2, The rotating structure includes an upper rotating shaft and a lower rotating shaft, the upper rotating shaft and the lower rotating shaft are hollow structures; the upper rotating shaft and the lower rotating shaft are respectively provided with an upper bearing and a lower bearing, and the upper bearing and the lower bearing are respectively provided with an upper bearing sleeve and the lower bearing sleeve, the upper turntable and the lower turntable are fixed on the upper bearing sleeve and the lower bearing sleeve respectively, that is, the upper turntable and the lower turntable are fixedly connected separately, and are not set on the same rotating shaft at the same time, so that the take-up turntable is easy to produce The phenomenon of eccentricity and unbalance affects the overall working effect. In view of the above problems, it is urgent to improve the lifting device
