Ultra-low lifting platform provided with connecting rod mechanism

Abstract

The invention discloses an ultra-low lifting platform provided with a connecting rod mechanism. The working condition demand that a lifting platform with an ultra-low starting point and a large load is required by engineering is met. According to key points in a technical scheme of the ultra-low lifting platform, a bottom plate opposite to a platform body is arranged at the bottom of the platformbody, two transmission parts are arranged on the bottom plate and are symmetrical about a reducer motor, each transmission part comprises a push block, a guide rail seat and a guide rail, the bottom of each push block is fixedly connected with the corresponding guide rail seat, the guide rails are fixedly connected with the center of the bottom plate, the reducer motor is fixedly connected with the bottom plate and located between the guide rails, each guide rail seat is connected with the corresponding guide rail in a sliding mode, the reducer motor and the two push blocks are controlled through a servo lead screw, connecting rod components are further included, each connecting rod component comprises a connecting rod, a mandrel and an ejector rod, the end, away from the reducer motor, ofeach push block is hinged to the center of the corresponding connecting rod, the two ends of each connecting rod are hinged to the corresponding ejector rod respectively, fixed mandrel seats are fixedly connected to the two ends of each mandrel respectively, the fixed mandrel seats are fixedly connected with the bottom plate, symmetrical supporting seats are arranged at the two ends of each ejector rod and are fixedly connected with flat plates, and the two ends of each ejector rod are hinged to the two ends of the corresponding connecting rod.

Description

technical field [0001] The invention relates to the technical field of lifting platforms, more specifically, it relates to an ultra-low lifting platform of a link mechanism. Background technique [0002] At present, it is difficult for the scissors mechanism to achieve ultra-low height and heavy load conditions in the lifting conditions with limited height in production and manufacturing. With the promotion of intelligent manufacturing, it is necessary for the factory to achieve the goal of miniaturization and intelligence. Occupying a small space, the demand for platforms that can be lifted from an ultra-low position will become more and more widely used. [0003] At present, the Chinese utility model patent with the publication number CN209367730U has announced a heavy-duty single-scissor lift platform, including a base, a support platform, and two groups of lifting mechanisms arranged between the base and the support platform; the lifting mechanism includes A connecting ...

Problems solved by technology

[0004] Although the above-mentioned device can avoid the tilting and jamming of the support platform caused by the asynchrony of the two lifting mechanisms, the scissor lift platform like this cannot be applied to the working conditions of lower heights, and it occupies a large area, which is not conducive to realizing the miniaturization and intelligence of the current factory. the idea of
