[0027] beam 10;

[0028] The first screw rod 90 and the second screw rod 100 have opposite thread sections and are respectively installed on both sides of the beam 10;

[0029] The first transverse plate 20 is vertically mounted on the bottom of the first end of the beam 10 and is connected to the first screw rod 90;

[0030] The second transverse plate 30 is vertically mounted on the bottom of the second end of the beam 10 and is connected to the second screw rod 100;

[0031] The first clamping assembly 40 is mounted on the bottom of the first horizontal plate 20;

[0032] The second clamping assembly 50 is mounted on the bottom of the second horizontal plate 30;

[0033] The driving assembly includes a first driving unit 60, a second driving unit 70 and a third driving unit 80; the first driving unit 60 is connected to the first screw rod 90 and the second screw rod 100, and is used to drive the first screw rod 90 and the second screw rod 100 to rotate; the second driving unit 70 is connected to the first clamping assembly 40, and is used to drive the first clamping assembly 40 to move along the first horizontal plate 20; the second driving unit 70 is connected to the second clamping assembly 50, and is used to drive the second clamping assembly 50 to move along the second horizontal plate 30.

[0034] Specifically, when the material needs to be moved from the bottom of the first end of the beam 10 to the bottom of the second end, the first clamping assembly 40 clamps and fixes the material. After the material is clamped and fixed, the second driving unit 70 works to drive the first clamping assembly 40 to move along the first transverse plate 20 to the end of the first transverse plate 20 away from the beam 10. After the first clamping assembly 40 moves into place, the first driving unit 60 drives the first screw rod 90 and the second screw rod 100 to rotate. Since the threaded sections of the first screw rod 90 and the second screw rod 100 are set in opposite directions, the first transverse plate 20 and the first clamping assembly 40 are fixed. 0 moves to the second end of the beam 10 and the unloading position, the second cross plate 30 and the second clamping assembly 50 move to the first end of the beam 10, that is, the initial position of the material, and then the second driving unit 70 drives the first clamping assembly 40 to reset. After resetting, the first clamping assembly 40 releases the material for unloading. At this time, the second clamping assembly 50 clamps and fixes the material at the initial position and continues to start the next cycle process; relatively speaking, when the material needs to be moved from below the second end of the beam 10 to below the first end, the above working steps can be obtained in the same way, which will not be repeated here.

[0035] Furthermore, in the above working process, the second drive unit 70 and the third drive unit 80 are set so that the first clamping assembly 40 and the second clamping assembly 50 can be moved from the clamping position (that is, the end of the first cross plate 20 / the second cross plate 30 close to the beam 10) to the avoidance position (and the end of the first cross plate 20 / the second cross plate 30 away from the beam 10), thereby avoiding the mutual interference between the first clamping assembly 40 and the second clamping assembly 50 when they move toward each other under the drive of the first drive unit 60; in addition, in this embodiment, the first cross plate 20 and the second cross plate 30 are located at one end of the bottom of the beam 10, and neither exceeds the center line position of the beam 10, thereby effectively avoiding the mutual interference between the first cross plate 20 and the second cross plate 30 when they move toward each other.
