Small-amplitude synchronous lifting platform

Abstract

The invention discloses a small-amplitude synchronous lifting platform which aims to achieve steady rising and descending of goods and can be applied to research and development of a rapid goods loading and unloading device. The small-amplitude synchronous lifting platform comprises an underframe 1, a carrier plate 19, a lifting driving motor 4, a motor shaft coupler 5, a bidirectional output speed reducer 6, a first speed reducer shaft coupler 3-1, a first transmission shaft 2-1, a first transmission mechanism 101-1, a second speed reducer shaft coupler 3-2, a second transmission shaft 2-2 and a second transmission mechanism 101-2, and further comprises eight longitudinal positioning retractable frames 10 and four driven roller groups 9, wherein the lifting driving motor 4 supplies power to the first transmission mechanism 101-1 and the second transmission mechanism 101-2 so as to enable the first transmission mechanism 101-1 and the second transmission mechanism 101-2 to drag the goods to rise and fall. The small-amplitude synchronous lifting platform overcomes the defects that the existing hydraulic lifting platform is fierce in vibration, large in deformation under a loaded condition and sensitive to a suddenly-changing load; the small-amplitude synchronous lifting platform not only has the characteristics of high stability and synchronization, but also has the characteristics of low cost and high efficiency, and can be applied to research and development of rapid loading and unloading equipment.

Description

technical field [0001] The invention relates to material handling equipment, in particular to a small-amplitude synchronous lifting platform used for lifting and lowering containers, brackets and pallets. Background technique [0002] At present, the loading and unloading equipment of existing goods, brackets and pallets generally adopts gantry cranes and forklifts. When using a gantry crane for cargo loading and unloading, precise positioning is required, and in order to prevent danger due to shaking during cargo hoisting, the hoisting speed is very slow. The purchase, use and maintenance costs of the equipment used are very high; when the forklift is used for loading and unloading goods, the carrying capacity of the forklift is small, and multiple forklifts are required to cooperate with each other to carry it at the same time. Dangers are prone to occur during the operation, and labor costs and equipment use and maintenance costs Also very high. If reorganization and lo...

Problems solved by technology

The purchase, use and maintenance costs of the equipment used are very high; when the forklift is used for loading and unloading goods, the carrying capacity of the forklift is small, and multiple forklifts are required to cooperate with each other to carry it at the same time. Dangers are prone to occur during the operation, and labor costs and equipment use and maintenance costs also very high

If the loading and unloading is carried out, a large number of gantry cranes and forklifts need to be purchased. The purchase cost is high and the floor area is large. Neither of these two methods can meet the requirements for the reorganization and fast simultaneous loading and unloading of freight vehicles in the future.
