Stacking device and battery replacement apparatus

Abstract

The invention relates to a stacking device and a battery replacement apparatus. The stacking device comprises a frame, a stacking walking mechanism, a hoisting mechanism and a fork mechanism, wherein the stacking walking mechanism comprises a walking motor and walking wheels; the hoisting mechanism comprises a hoisting motor, a hoisting drive sprocket wheel, a hoisting tensioning sprocket wheel, a hoisting chain and a tray assembly; the hoisting motor is mounted on the frame; the hoisting drive sprocket wheel is connected with the hoisting motor; the hoisting tensioning sprocket wheel is arranged on the frame; the hoisting chain is arranged on the hoisting drive sprocket wheel and the hoisting tensioning sprocket wheel in drive and sleeving manners; the tray assembly is fixed with the hoisting chain; the fork mechanism comprises a fork motor, a fork gear, a fork gear rack and a fork plate; the fork gear rack is meshed with the fork gear; the fork plate is fixed with the fork gear rack. By arranging the stacking walking mechanism, the hoisting mechanism and the fork mechanism, which cooperate with one another, the stacking device can be used for realizing picking and placing operations carried out on an object, and is compacter in structure. In addition, compared with a conventional drive structure, the hoisting mechanism is smoother in going up and down and more reliable in safety performance.

Description

technical field [0001] The invention relates to the field of automatic machinery, in particular to a stacking device and power exchange equipment. Background technique [0002] At present, stacking devices are used in common equipment in industries such as new energy power exchange, warehouse access and transfer, for example, in power exchange equipment. The lifting principle of these stacking devices generally adopts the cooperation of steel wire ropes and rollers, and the objects are lifted and lowered by winding. [0003] However, the lifting device with this structure can only provide the pulling force for the upward movement of the pallet. When the pallet moves downward, it can only be lowered by its own weight. If the pallet is jammed, the wire rope will often become loose. , so that the safety performance of the whole machine is greatly reduced. [0004] Moreover, it is difficult for the steel wire rope to achieve a better response speed during the process of rising...

Problems solved by technology

[0003] However, the lifting device with this structure can only provide the pulling force for the upward movement of the pallet. When the pallet moves downward, it can only be lowered by its own weight. If the pallet is jammed, the wire rope will often become loose. , so that the safety performance of the whole machine is greatly reduced

[0004] Moreover, it is difficult for the steel wire rope to achieve a better response speed during the process of rising or falling, that is, the lifting is not stable enough. In order to overcome this problem, it is often necessary to hang a large roller on the stacker to increase the weight, and multiple Pulley blocks are used to increase stability, however, this will make the entire lifting device appear more prominent and bulky in structure, and not compact enough
