Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] Such as Figure 1 to Figure 6 As shown in , a lifting device comprising

[0029] Base 1, lifting platform 2, lifting gear 3, chain rail and tooth chain 4 that can slide along the chain rail;

[0030] The tooth chain includes a plurality of sequentially hinged chain link monomers 41; any adjacent two chain link monomers are hinged through a hinge structure, and the hinge structure includes a hinge plate 42 and four hinge shafts 43 that are rotatably connected to the hinge plate. Among the two adjacent chain link monomers: one chain link monomer rotates with one hinge shaft, and the other chain link monomer rotates with the remaining three hinge shafts;

[0031] The chain link monomer is provided with a slider that can slide and fit with the chain rail, and the base is provided with a chain box 5, the chain box includes an upright box 51...

Abstract

The invention discloses a lifting device. The lifting device comprises a base, a lifting table, a lifting gear, a caterpillar track and a tooth chain capable of sliding along the caterpillar track; chain link units are provided with a sliding block which can cooperate with the caterpillar track in a sliding mode, and a chain box is arranged on the base; the chain box comprises a vertical box and ahorizontal box, wherein a top box opening used for allowing the tooth chain to pass through is formed in the top of the vertical box, and a gear shaft is arranged on the vertical box; a motor used for driving the gear shaft to rotate is arranged in the vertical box, and the chain link units are provided with a rack which can be meshed with the lifting gear; and one end of the tooth chain is connected with the lifting table, and the vertical box is provided with a nozzle which is used for jetting air to the chain link units above the top box opening. The lifting device has the beneficial effects that a lifting structure on a stage can be effectively lifted, continuity is good in the lifting process, supporting capacity is good, a descending process is stable, the overall height is relatively low after the descending is carried out, and the space occupied in the height direction is small. The lifting device has continuous cleaning capability and can prevent sundries from being clamped into a moving part, so that safety and a service life are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of stage machinery, and in particular relates to a lifting device. Background technique [0002] In the stage field, structures that need to be lifted are often encountered, such as two-level stage, multi-level stage, movable stage ladder, lifting stage set and so on. At present, the lifting structure on the stage is mainly driven by the sprocket mechanism, oil cylinder lifting mechanism, electric slider mechanism, etc. Although these mechanisms can realize the lifting function, they often need to occupy a lot of space in the height direction. Cause transportation, storage inconvenience. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a lifting structure that can effectively lift the stage, which has good continuity and good supporting capacity during the lifting process, and is stable and stable during the falling proces...
