Description

TECHNICAL FIELD

[0001] The utility model relates to stage equipment technical field especially a kind of multi-line way coaxial same center take-up device. BACKGROUND

[0002] In order to obtain specific visual effect, some entertainment, show place or exhibition stand adopts the lamp, display screen, prop that can be lifted. In order to make these props have the function of lifting, the prior art basically needs to use small prop hoist for lifting props, such as Chinese patent publication No. CN209974180U, a double cable stage prop hoist, including winding module and drive module, the drive module includes two head shaft motor and drive board for driving two head shaft motor, the winding module includes first winding disc and second winding disc, the first winding disc and second winding disc are in the same plane, the first output shaft of two head shaft motor drives first winding disc through first transmission mechanism, the second output shaft of two head shaft motor drives second winding disc through second transmission mechanism. This kind of hoist only has a group of winding discs, so it can only lift one stage prop. SUMMARY

[0003] The technical problem to be solved by the utility model is to provide a multi-line way coaxial same center take-up device, which can simultaneously lift multiple stage props and can arrange them in layers.

[0004] To solve the above technical problems, the technical scheme of the utility model is as follows: a multi-line way coaxial same center take-up device, comprising a transmission shaft and a plurality of take-up disc sets with different diameters and arranged on the transmission shaft, each take-up disc set comprising two take-up discs arranged opposite to each other, the take-up discs winding cables, and the two cables corresponding to each take-up disc set being connected to a prop. The utility model principle is that one transmission shaft simultaneously drives multiple take-up disc sets to lift multiple stage props, and different diameter take-up disc sets are arranged to drive multiple stage props to lift in layers.

[0005] As an improvement, the take-up disc comprises a cylinder core and baffles arranged at both ends of the cylinder core, a cable slot for accommodating cables being formed between the two baffles, and the transmission shaft passes through the cylinder core.

[0006] As an improvement, the take-up discs on the same side and adjacent to each other share a baffle.

[0007] As an improvement, the diameters of the take-up discs on the same side gradually increase from inside to outside, or gradually decrease from inside to outside.

[0008] As an improvement, the prop is in the shape of a long strip, and the two cables of each take-up disc set are connected to the two ends of the prop.

[0009] As an improvement, the two cables of each take-up disc set are wires capable of conducting signals or currents.

[0010] As an improvement, the prop is an LED light fixture.

[0011] The beneficial effects of this utility model compared with the prior art are:

[0012] Multiple stage props can be raised and lowered simultaneously by driving multiple take-up reels with a single drive shaft; multiple stage props can be raised and lowered in layers by setting take-up reels of different diameters. Attached Figure Description

[0014] Figure 2 This is a schematic diagram of receiver state II. Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] like Figure 1 , 2 As shown, a multi-track coaxial concentric take-up device includes a drive shaft 1 and several take-up reels with different diameters mounted on the drive shaft 1. In this embodiment, there are a total of four take-up reel groups, which can correspond to four stage props. The take-up reel assembly includes two take-up reels 2 arranged opposite each other on the left and right sides of the drive shaft 1, so that the drive shaft 1 can be balanced when rotating. Each take-up reel 2 includes a core and baffles at both ends of the core. The drive shaft 1 passes through the core, and a groove for accommodating the cable 3 is formed between the two baffles. The cable 3 is wound in the groove of the take-up reel 2. The deeper the groove, the longer the cable 3 can be wound. The take-up reels 2 on the same side and adjacent to each other share a baffle, that is, the take-up reels on the same side are connected as one piece, which is simple in structure and easy to install. The diameter of the take-up reels 2 on the same side gradually increases or gradually decreases from the inside to the outside. In this embodiment, the core diameters of the four take-up reels 2 are 80mm, 180mm, 240mm and 320mm respectively. The two cables 3 corresponding to the take-up reel assembly are connected to the prop. The lifting and lowering of the prop is achieved by the take-up and lowering of the cable 3 by the take-up reels 2. The larger the diameter of the take-up reel 2, the faster the lifting and lowering speed of the prop. The prop is long and narrow. The two cables 3 of the take-up reel are connected to the two ends of the prop respectively. The two cables of the take-up reel are wires that can conduct signals or current. In this embodiment, the prop is an LED light fixture 4.

[0017] The principle of this utility model is as follows: multiple take-up reels are driven simultaneously by a single drive shaft 1 to lift and lower multiple stage props; multiple stage props are lifted and lowered in layers by setting take-up reels of different diameters.
