Compact type lifting device

Abstract

The invention discloses a compact type lifting device. The compact type lifting device comprises a box body, a rolling executing mechanism and a rolling assisting mechanism, wherein the rolling executing mechanism is arranged inside the box body; the rolling assisting mechanism is matched with the rolling executing mechanism and is used for assisting the rolling of a wire; the box body is providedwith a wire inlet and a wire outlet; the rolling executing mechanism comprises a rolling roller and a rotation driving mechanism which is used for driving the rolling roller to rotate to implement rolling and unrolling; the rolling assisting mechanism is arranged at one side of the rolling roller and comprises a mobile frame and a movement driving mechanism, wherein the mobile frame is used for limiting the position, in the axis direction of the rolling roller, of a wire which is being rolled; the movement driving mechanism is used for driving the mobile frame to move in the axis direction ofthe rolling roller; the mobile frame is provided with a positioning part used for positioning the wire; and the wire is rolled on the rolling roller after bypassing the positioning part. The compacttype lifting device has the advantages of being capable of rolling a long wire and small in size.

Description

technical field [0001] The invention relates to a kinetic energy lamp, in particular to a kinetic energy lamp lifting device. Background technique [0002] In order to obtain specific lighting effects, some kinetic energy lamps used in the prior art have a lifting function, and the kinetic energy lamps can perform lifting movements during use. Specifically, one end of the kinetic energy lamp is connected to a wire, and the wire not only plays a role in suspending the kinetic energy lamp, but also plays a role in energizing the kinetic energy lamp; during work, when the kinetic energy lamp needs to perform lifting tasks, by controlling the kinetic energy lamp lifting device Elevate the task after coming. [0003] The existing kinetic energy lamp lifting device is mainly composed of an outer box, a winding mechanism, a winding power mechanism, etc., and the winding mechanism and the winding power mechanism are arranged in the outer box. [0004] For example, the utility mode...

AI Technical Summary

Problems solved by technology

[0005] Refer to the description of the above-mentioned patent documents and in the accompanying drawings of the description image 3 It can be seen that when the winding shaft is wound, the wires are arranged outward layer by layer along the radial direction from the winding shaft. , can only be arranged in one layer along the axial direction of the rewinding shaft), the following problems will be caused during use: 1. When the wire to be rewound is long, the rewinding space needs to be increased, that is, the box needs to be increased. However, in actual application, since the kinetic energy lamps are hung side by side on the horizontal fixed frame, when the volume of the box increases, the distance between the kinetic energy lamps will increase, and the distance between the kinetic energy lamps cannot be arranged according to the set distance, so that the kinetic energy The number of lamps is reduced, which affects the specific lighting effect; 2. When the volume of the box does not increase and meets the layout spacing of the kinetic energy lamp, the length of its winding is limited, which cannot meet the lifting stroke requirements of the kinetic energy lamp
