The invention relates to a single-shaft weight block balanced type fast lifting rack which has the structure that a power shaft is arranged at one side of the top of a main machine frame, and a driven shaft is arranged at the other side of the top of the main machine frame; a motor is connected with the power shaft and drives the power shaft; both ends of the power shaft are respectively provided with a first transmission chain wheel and a second transmission chain wheel which have double-row chain wheel structures; both ends of the driven shaft are respectively provided with a third transmission chain wheel and a fourth transmission chain wheel which have single-row chain wheel structures; the four transmission chain wheels are provided with four meshed chains in all, one end of each chain is connected with a balanced weight block so that the balanced weight block is hung at one side of the main machine frame, and the other ends of the four chains respectively hang four angels of a lifting flat plate; and when the power shaft rotates, as the lifting flat plate raises, the balanced weight block falls. The invention has simple and novel structure, easy control under the balanced action of the balanced weight block, reduced driving force and braking force and lower energy consumption.
Description
technical field [0001] The invention relates to an accessory part of a stacker, in particular to a single-axis heavy-block balanced type quick-lifting and landing frame. Background technique [0002] A stacker is an automated device that stacks bagged or boxed items on a lifting platform according to a prescribed pattern. The fast lifting frame is the key part of the stacker, which is mainly used to carry the material stack in the stacker, and pull the material stack up and down quickly according to the needs of the working procedure to realize the stacking operation. The traditional landing frame mainly has two working structures, one is the lifting method of the cantilevered flat oil cylinder, and the other is the driving method of the cantilevered flat rotary chain. The weights are balanced, but their structure is complex, maintenance is difficult, and the energy consumption in practical application is relatively high. Contents of the invention [0003] The object of ...
