Embodiment 3

[0034] The structure of this embodiment is shown in Figure 3(a). The difference between this embodiment and Embodiment 2 is that a 4-2 arrangement is adopted, that is, four fixed-length links are connected in parallel between the support base 1 and the lifting platform 4. Rods 61, 62, 63, 64 are connected in parallel with two fixed-length connecting rods 65, 66 between the lifting platform 4 and the horizontally moving slider 3. The fixed-length connecting rods 61, 62, 63, 64 are respectively connected to the lifting platform 4 through spherical hinges 71, 72, 73, 74, and the fixed-length connecting rods 61, 62, 63, 64 are respectively connected through spherical hinges 51, 52, 53, 54 Linked to the support base 1; fixed-length connecting rods 65, 66 are connected to the lifting platform 4 through spherical hinges 75, 76 respectively, and fixed-length connecting rods 65, 66 are connected to the horizontally moving slider 3 through spherical hinges 55, 56 respectively. Because t...

Abstract

The invention provides a lifting mechanism of stereoscopic spatial layout. The lifting mechanism comprises a supporting base, a linear guide rail, a horizontal movement sliding block, a lifting platform, spherical hinges, fixed-length connecting rods and a horizontally-arranged hydraulic drive device, wherein six and more stereoscopically-arranged fixed-length connecting rods are connected betweenthe lifting platform and the supporting base as well as between the lifting platform and the horizontal movement sliding block in parallel, the driven spherical hinges are arranged at the two ends ofthe fixed-length connecting rods, the horizontal movement sliding block is directly connected with the linear guide rail, and a telescopic rod of the hydraulic drive device is connected with the horizontal movement sliding block so as to control rising and falling of the lifting mechanism. The lifting mechanism is a parallel mechanism, and compared with a traditional lifting mechanism of a planestructure, the lifting mechanism has a good stress state, has good spatial rigidity and particularly lateral rigidity, and is higher in bearing capacity and better in safety.

Description

technical field [0001] The invention belongs to the technical field of lifts, and in particular relates to a lifting mechanism with a three-dimensional space layout. Background technique [0002] Lifting work platform is a multi-functional lifting machinery equipment, which can be divided into fixed type and mobile type, guide rail type, crank arm type, scissor type, chain type, loading and unloading platform, etc. Wherein, the most commonly used is the scissor lift, as authorized announcement number is Chinese patents such as CN2064776705U, CN206359216U, is widely used in aerial work. Among them, the scissors structure makes the lifting platform have higher stability, wide operating platform and higher carrying capacity, which makes the range of high-altitude operation larger and suitable for multiple people to work at the same time, and improves work efficiency. [0003] Although the scissor structure lifting table has many advantages, there are still some problems in thi...
