Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of storing single or sequentially arranged objects in a warehouse or storage, and in particular to a high-speed stacking machine. BACKGROUND

[0002] The lifting mechanism of the stacking machine is used to realize the vertical lifting of the material, and mainly adopts three ways of chain lifting, steel wire rope drum lifting and steel wire rope traction wheel lifting to lift the material.

[0003] The steel wire rope drum lifting is generally composed of a drum, a speed reducer motor, a steel wire rope and a pulley set, and its working principle is that the speed reducer motor drives the drum to rotate and wind the steel wire rope, and then the steel wire rope and the pulley set lift the heavy object, but the lifting speed is slow;

[0004] The traction type lifting mechanism is mainly composed of a traction force device, a traction wheel, a steel wire rope, a guide wheel and a reverse pulley, one end of the traction steel wire rope is connected to the loading platform, and the other end is connected to the counterweight device, the gravity of the loading platform, the counterweight device and the load makes the steel wire rope tightly pressed in the traction wheel groove to generate sufficient friction force to drive the heavy object to move up and down along the guide rail; The advantage of the traction type lifting mechanism is that the transmission mechanism is small in size, but the stacking machine and the elevator are different in that they need to move horizontally, so the counterweight device will inevitably sway and produce noise, and the counterweight device needs to be set inside the stand column and move up and down along the inner wall of the stand column, which is more troublesome to maintain and install;

[0005] The chain lifting mechanism is mainly composed of a lifting motor (including a speed reducer), a transmission sprocket, a transmission chain, a double sprocket, a lifting chain and a reversing sprocket, when the lifting motor drives the double sprocket to rotate through the transmission chain, the lifting chain moves, thereby driving the loading platform (including forks (403), goods) to lift. Compared with the steel wire rope, the garage using the chain lifting method has much better stability during lifting, but the chain will make a loud noise during lifting.

[0032] A lower cross beam 10 is horizontally arranged in the left-right direction, and a walking mechanism 20 is installed on the lower cross beam 10;

[0033] Two vertical columns 30 are vertically installed on the walking mechanism 20,

[0034] A loading platform 40 is arranged between the two vertical columns 30, and the upper end of the loading platform 40 is provided with upper pulleys 50 on the left and right sides, respectively, and the lower end is provided with lower pulleys 60 on the left and right sides, respectively.

[0035] A transmission belt 70 is arranged on each of the vertical columns 30, one end of the transmission belt 70 is fixedly connected with the upper end of the vertical column 30, and the other end sequentially passes through the same side upper pulley 50, the upper end of the vertical column 30, the driving wheel assembly 80, the lower end of the vertical column 30, and the lower pulley 60, and is fixedly connected with the lower end of the vertical column 30.

[0036] In this embodiment, the first end of the transmission belt 70 is defined as the first end, which is connected and fixed to the upper end of the column 30. The second end of the transmission belt 70 is defined as the second end, which is connected and fixed to the lower end of the column 30. Referring to the drawings, the upper end and the lower end of each column 30 are respectively provided with two fixed wheels 301. The second end of the transmission belt 70 is downward and passes through the upper pulley 50, then upward and passes through the two fixed wheels at the upper end of the column 30, then downward and passes through the driving wheel assembly 80, then the second end of the transmission belt 70 passes through the two fixed wheels at the lower end of the column 30, then upward and passes through the lower pulley 60, and finally is connected and fixed to the lower end of the column 30.

[0037] When the transmission belt 70 passes through the driving wheel assembly 80, the transmission belt 70 is divided into two sections by the driving wheel assembly 80.
