Embodiment Construction

[0017] The present invention is further described in conjunction with the following examples.

[0018] The specific embodiment of the multi-stage screw rod 3 for lifting and the lifting cylinder 11 combination lifting device of the present invention, such as figure 1 and figure 2 As shown, it includes a pressure-bearing platform 8, three movable platforms and a lower supporting frame 10 that are sheathed on the guide rails from top to bottom. The guide rail is assembled from a plurality of stacked and fixed standard sections, and each standard section is provided with a draw-in slot for the working end of the telescopic corbel 9 to be inserted into. Both the pressure-bearing platform 8 and the lower support frame 10 are provided with telescopic corbels 9, and as a preferred solution, the lower support frame 10 is provided with two telescopic corbels 9, and the two telescopic corbels 9 are symmetrically installed on the bottom of the lower support frame 10 respectively. The ...

Abstract

The invention relates to the technical field of building constructing machines, in particular to a multistage screw rod and lifting oil cylinder combined lifting device used for lifting. The multistage screw rod and lifting oil cylinder combined lifting device comprises a pressure bearing platform, at least two movable platforms and a lower supporting frame, wherein the pressure bearing platform, the movable platforms and the lower supporting frame are sequentially arranged on a guide rail in a sleeving manner from top to bottom. Telescopic brackets are arranged on the pressure bearing platform and the lower supporting frame, and multiple clamping grooves used for insertion of the work ends of the telescopic brackets are formed in the guide rail at intervals in the vertical direction. The movable platform comprises lifting oil cylinders, a movable supporting beam and screw rod supporting beams which are parallel to the movable supporting beam and are located on the two sides above the movable supporting beam. The lifting oil cylinders are fixedly installed on the movable supporting beam. Synchronous lifting nuts are inlaid in the side portions of the screw rod supporting beams, and the screw rod supporting beams are provided with fast return nuts coaxial with the synchronous lifting nuts. Compared with the prior art, the phenomena that cracking of the lifting oil cylinders happens, and screw rods or the pressure bearing platform suddenly fall can be prevented, and therefore the safety performance of the lifting device is ensured, and the problem that safety is poor in the past is solved.

Description

technical field [0001] The invention relates to the technical field of building machines, in particular to a combined lifting device for lifting a multi-stage screw rod and a lifting oil cylinder. Background technique [0002] The new technology of industrial intelligent construction "air building machine" is an equipment platform and supporting construction technology independently developed by my country. The aerial building machine and construction technology realize the industrial intelligent construction of high-rise residential cast-in-place reinforced concrete by means of mechanical operation and intelligent control. One of its obvious features is that the entire process is concentrated and completed layer by layer in the air. [0003] At present, the aerial building machine includes four standard section groups arranged in a rectangular array, a lifting mechanism and a pressure-bearing platform. Specifically, multiple standard sections are superimposed and fixed in ...
