Embodiment Construction

[0023] The preferred embodiments of the present invention will be described in detail below with reference to the drawings.

[0024] The structure of the lifting device for driving the working platform up and down according to the preferred embodiment of the present invention is shown as follows: figure 1 shown, see also image 3 , the lifting device includes a fixed frame 5 for connecting the working platform 6, and also includes a guide frame 2 and a sprocket assembly 1. The work platform 6 can be a stage, or a platform for other operations.

[0025] Among them, such as figure 2 As shown, the sprocket assembly 1 includes a sprocket 11 and a chain 14 wound on the sprocket 11 , one end of the chain 14 is fixedly connected to the fixing frame 5 , and the other end is fixedly connected to the guide frame 2 . The sprocket 11 is arranged on the guide frame 2 so as to slide and rotate relatively.

[0026] In this embodiment, the lifting device further includes a driving device...

Abstract

The invention relates to a lifting device and a stage structure using the same. The lifting device comprises a fixing support for being connected with an operating platform, a guide frame, a chain wheel assembly and a drive unit, wherein, the chain wheel assembly comprises a chain wheel and a chain wound on the chain wheel, one end of the chain is fixedly connected with the fixing support, the other end of the chain is fixedly connected on the guide frame, and the chain wheel is arranged on the guide frame in relative slip and relative rotation manners; and the drive unit drives the chain wheel to rise and fall along the guide frame so that the chain drives the fixing support to rise and fall so as to realize lifting operation of the operating platform. The lifting device has the advantages that motion stroke of an oil cylinder is increased by means of the chain wheel and the chain, thus reducing installation size of the lifting device; and the operating platform can stably rise and fall under guidance of guide shoes and guide rails.

Description

technical field [0001] The invention relates to the field of lifting machinery and equipment, in particular to a guide rail type hydraulic lifting device and a stage structure using the lifting device. Background technique [0002] In the current stage structure, especially in the large and medium-sized stage structure, in order to achieve the ideal stage effect, lifting equipment is already an indispensable part of the structure. [0003] The lifting mechanical equipment in the prior art generally uses oil cylinders to lift directly, or uses oil cylinder scissors to lift, or directly uses wire ropes or motor chains to achieve lifting, but the above several lifting methods are either too large in installation size, or the lifting is not stable. , It is not suitable for the current stage structure with faster and faster development and higher and higher installation requirements, and it cannot guarantee the safety of actors. Contents of the invention [0004] The technical...
