[0006] The column is a hollow structure matched with the counterweight block, and the counterweight block is arranged in the cavity of the column.

[0007] A notch is provided on the upper portion of the column.

[0008] The fixed pulley is fixed on the top of the column, and the notch on the upper part of the column is close to the fixed pulley.

[0009] The rack and guide wheel on the driving side of each cantilever platform are respectively fixed on the cantilever platform.

[0010] The guide column is provided with a guide groove which matches the guide wheel.

[0011] The beneficial effects of the present invention are: it can eliminate the overturning force generated when the cantilever platform receives the load, avoid accidents such as the cantilever platform falling off, thereby increasing the frequency and output of rolled pieces off the line, reducing equipment accidents and spare parts consumption, and reducing the workload of the drive device, saving power consumption, and effectively solving the above-mentioned problems existing in the background technology.

DETAILED DESCRIPTION

[0018] The present invention will be further described below with reference to the accompanying drawings and examples.

[0019] Refer to the attached Figure 1-5 A cantilever stacker with a load adjustment function includes several cantilever platforms 8 for supporting rolled pieces, one side of the cantilever platform 8 is the cantilever side, and the other side is the driving side. The cantilever side of each cantilever platform 8 is equipped with a column 14, and a fixed pulley 11 is fixed on each column 14. The cantilever side of each cantilever platform 8 uses a steel wire rope 12 to pass around the fixed pulley 11 and is connected to the counterweight block 13; the driving side of each cantilever platform 8 is provided with a rack 5 and a guide wheel 7, the rack 5 is engaged with the gear 4, the gear 4 is fixed on the drive shaft 3, and the guide wheel 7 is connected to the guide column 1 for up and down rolling.

[0020] In this embodiment, refer to the attached Figure 5 The cantilever type palletizer includes six cantilever platforms 8, six columns 14 and a driving shaft 3, and the driving shaft 3 is provided with six gears 4.

[0021] The column 14 is installed on the ground foundation, and each cantilever platform 8 is equipped with one. It is hollow in form, and the counterweight 13 is placed in the middle to prevent the counterweight 13 from shaking. A notch 27 is provided on the upper part of the column 14 for adjusting the number of counterweights, as shown in the attached figure. Figure 1 、 2 shown.

[0022] A fixed pulley 11 can be mounted on the top of the column 14. The fixed pulley 11 is mounted on a bearing 16 and a shaft 17. A steel wire rope 12 is placed on the fixed pulley to bear the weight of the counterweight 13 and apply a pulling force to the cantilever end of the cantilever platform. The bearing 16 is mounted on the shaft 17 to support the fixed pulley. The shaft 17 is fixed to the base 21 via a baffle 19 and bolts 20 to support the bearing 16. The spacer sleeve 18 is used to axially locate the bearing 16. The baffle 19 is used to axially fix the shaft 17 and prevent its circumferential rotation. The base 21 is mounted on the column 14.

[0023] The guide column 1 is mounted on the ground foundation, and the guide wheel 7 is fixedly connected to the drive side of the cantilever platform 8 by bolts 9. The guide wheel 7 is placed in the guide groove 28 of the guide column 1. At the same time, a rack 5 is also installed on the drive side of the cantilever platform 8, which forms a gear pair transmission with the gear 4 on the drive shaft 3.

[0024] Refer to the attached Figure 1 The forward and reverse rotation of the drive shaft 3 drives the rack 5 up and down. The upper surface of the cantilever platform 8 is used to place the workpiece. The weight of the workpiece can be balanced by adjusting the number of counterweights 13 to ensure that the weight on both sides of the cantilever platform 8 is similar. The notch 28 on the upper part of the column 14 is an exposed space, and the number of counterweights 13 can be adjusted to adjust the load balance.
