Oblique block-type elevating platform

Abstract

The invention discloses an oblique block-type elevating platform. A threaded shaft performing fixed-axis rotation is provided with left and right sections of external threads with opposite rotary directions. Left and right sliding blocks matching the threaded shafts are respectively provided with internal threads with left and right rotating directions. A small hand wheel at the right end is fixedly connected with the threaded shafts. By rotating the hand wheel, the left and right sliding blocks perform motion in the opposite directions. With positions of the sliding blocks changing, a platform surface can ascend and descend. A bottom plate of the platform is provided with chutes having adjustable gaps in which the sliding blocks can slide. Left and right support plates are used for locating the threaded shafts. Holes of the support plates are beset with copper sleeves. Two oblique blocks are linked by a linkage plate and placed on the two sliding blocks. Upper pressing plates and upper blocking plates of the sliding blocks can play a falling-prevention and guiding effect. The platform surface is fixedly connected with the oblique blocks. After the height is adjusted, screws are tightened so that the platform is locked. Four bolt through holes are arranged in the bottom plate of the platform. The oblique block-type elevating platform has following beneficial effects: the oblique block-type elevating platform is compact in structure; compared with an ordinary oblique-gear elevating mechanism and a shear-type elevating mechanism, the platform is high in support rigidity and low in cost.

Description

technical field [0001] The invention relates to a lifting platform, in particular to an inclined block type lifting platform. Background technique [0002] In the field of mechanical engineering, lifting platforms are widely used. At present, the common lifting platforms on the market mainly include: scissor lifting platform, helical gear lifting platform, screw lifting platform, etc. The manufacturing and processing costs of these mechanisms are relatively high, and the supporting rigidity is slightly insufficient, and it is often necessary to add additional guide rails to meet the requirements of supporting rigidity. Among them, the structure of the scissor lifting mechanism is more complicated, and the supporting area is small, which makes it difficult for the mechanism itself to bear large loads or alternating loads; The problem of insufficient support rigidity. Contents of the invention [0003] The technical problem mainly solved by the present invention is to pro...
