The present invention also proposes a method for transporting a cargo logistics warehousing transport device, which specifically comprises the following steps:

S1. Place the goods - place the goods on the boxes and stack them neatly;

S2, lifting goods - start the electric push rod, the output shaft of the electric push rod drives the push block to move, and then drives the first slider to move, the first support rod and the second support rod perform a scissor motion, so that the pallet and the placement box are lifted in the vertical direction. At this time, the second slider will move to the right along the second slide groove, and then drive the support block to move, and then drive the fixed plate and the push plate to move to the right, the push plate gradually squeezes the goods, pushes the goods to prevent the goods from rolling, and as the height gradually increases, the distance between the fixed plate and the goods gradually decreases, the first spring will be squeezed, so that the distance between the fixed plate and the push plate is reduced, and further, the third slider will move in the third slide groove accordingly. When it moves to a predetermined height, the lifting action stops, the second spring pushes the card block and the card slot to engage, and then the position of the third slider is locked. Further, when the third slider is moving, rolling friction occurs between the straight cylinder and the third slider, and when the lifting action stops, static friction occurs between the straight cylinder and the third slider;

S3, unloading - after lifting to the picking height, close the electric push rod and take out the goods from the box.

S4. Reset loading - pull out the limit rod and rotate it 180°, reverse the direction of the inclined limit part and then release it. When descending, the fourth slider can move along the limit part, and the limit rod is pushed back into the installation opening. After reloading, when the height needs to be raised, turn the limit rod 180° again according to the above steps. When raising the height, normal adjustment can be made. After the height adjustment is completed, the limit part on the limit rod can form a matching support with the alignment groove, thereby improving the support stability.

Compared with the prior art, the present invention has the following beneficial effects:

1. In the present invention, a push plate is set and the electric push rod is started. The output shaft of the electric push rod drives the push block to move, and then drives the first sliding block to move. The first support rod and the second support rod perform a scissor motion, so that the support plate and the placement box are lifted in the vertical direction. At this time, the second sliding block will move to the right along the second sliding groove, and then drive the supporting block to move, and then drive the fixed plate and the push plate to move to the right. The push plate gradually squeezes the goods and pushes the goods, thereby making the goods more stable, thereby preventing the goods from rolling. As the height gradually increases, the distance between the fixed plate and the goods gradually decreases, and the first spring will be squeezed, so that the distance between the fixed plate and the push plate is reduced, thereby fixing the goods and improving the height of the device. The cooperation of the limit groove and the limit block can prevent the inner rod from moving excessively.

2. In the present invention, by setting a support rod, the third slider will move accordingly in the third slide groove. When it moves to a predetermined height, the lifting action stops, and the second spring pushes the card block and the card groove to engage, thereby locking the position of the third slider, so that the support rod can stably support the support plate, thereby improving the stability of the device during lifting. The cooperation between the movable groove and the movable block can prevent the card block from moving excessively and limit it.

3. In the present invention, by setting a straight cylinder, when the third slider is moving, rolling friction occurs between the straight cylinder and the third slider, thereby reducing the movement resistance of the third slider, making the lifting process more flexible, and when the lifting action stops, static friction occurs between the straight cylinder and the third slider, thereby improving the fixing effect of the third slider, thereby further improving the stability of the support plate.

4. In the present invention, by setting a limit rod, the limit rod is pulled out and rotated 180 degrees, the direction of the inclined limit portion is reversed and then released, and the fourth slider can move along the limit portion when descending, and the limit rod is pushed back into the installation opening. After reloading, when the height needs to be raised, the limit rod is rotated 180 degrees again according to the above steps, and normal adjustment can be performed when the height is raised. After the height adjustment is completed, the limit portion on the limit rod can form a matching support with the alignment groove, thereby improving the support stability.
