[0026] The lifting mechanism includes a lead screw 5 rotatably connected to the support column 1, a servo motor 7 fixed to one end of the support column 1 and driven towards the lead screw 5, a lead screw sleeve 6 threadedly connected to the outer wall of the lead screw 5, and a support plate 8 fixed to one end of the lead screw sleeve 6.

[0027] The stabilizing mechanism includes a mounting base 10 fixed to the bottom of the track beam 3, an insert block 11 slidably connected to one end of the mounting base 10, and a servo electric cylinder 12 fixed to one end of the mounting base 10.

[0028] The track beam 3 is supported by two pillars 1. With the cooperation of the sliding sleeve 2, the track beam 3 can slide stably up and down on the outer wall of the I-shaped pillar 1. The lifting mechanism of the pillar 1 controls the sliding sleeve 2 to move up and down, which controls the track beam 3 to move up and down. The servo motor 7 controls the screw 5 to rotate, which drives the screw sleeve block 6 and the support plate 8 to move for lifting control. The stabilizing mechanism is mainly composed of the mounting base 10 and the insert block 11 to assist the screw sleeve block 6 in supporting the track beam 3 and providing more stable support.

[0029] More preferably, one end of the sliding sleeve 2 is fixed with two symmetrical connecting rods 9, and one end of the two connecting rods 9 is respectively locked and fixed to both ends of the support plate 8 by bolts;

[0030] The sliding sleeve 2 is connected to the two connecting rods 9 and the two support plates 8 of the lead screw sleeve block 6, that is, the sliding sleeve 2 is driven by the lead screw sleeve block 6.

[0031] More preferably, the outer wall of the support column 1 is provided with a plurality of adjustment holes 13 in sequence, the telescopic end of the servo electric cylinder 12 passes through the mounting base 10 and is fixedly connected to one end of the plug block 11, and one end of the plug block 11 is inserted into one adjustment hole 13 of the support column 1.

[0032] The support column 1 has multiple adjustment holes 13 for use with the plug 11 during lifting and adjustment, for the plug 11 to be inserted, positioned and supported.

[0033] More preferably, the outer wall of the support column 1 is provided with an auxiliary opening 4, and the lead screw 5 is vertically rotatably connected to the auxiliary opening 4 of the support column 1;

[0034] The support column 1 is vertically mounted with a lead screw 5 through the auxiliary port 4 to assist in the vertical lifting operation.

The two pillars 1 can control the track beam 3 to move up and down for height adjustment through a lifting mechanism. During the adjustment process, the servo motor 7 can control the forward or reverse rotation of the lead screw 5. When the lead screw 5 rotates, the lead screw sleeve 6 can only move up and down due to the restriction of the support plate 8 and the auxiliary port 4. After the lead screw sleeve 6 is connected to the connecting rod 9 of the sliding sleeve 2 through the support plate 8, its movement drives the track beam 3 to move up and down. Through the multiple adjustment holes 13 of the pillar 1, multiple positions can be adjusted to meet the lifting height requirements of more and more large and small goods. When adjusting the height, the servo electric cylinder 12 of the stabilizing mechanism controls the insertion block 11 of the mounting base 10 to move horizontally. When adjusting, the insertion block 11 is moved away from the corresponding adjustment insertion block 11. After the position is determined, the insertion block 11 is controlled to be inserted into the corresponding adjustment insertion hole 13 of the pillar 1. The insertion block 11 and the mounting base 10 jointly assist the lead screw sleeve 6 in supporting and lifting the track beam 3, so as to stably carry out the lifting operation.
