[0047] The transfer device in this embodiment can move the front and rear positions of the transfer pallet 2 on the fork 1 along the length direction of the fork 1 according to the length and weight of the transfer object 100 placed on the transfer pallet 2, and then use the locking mechanism 3 to fix the transfer pallet 2 and the fork 1, so as to flexibly adjust the force position of the fork 1 to adapt to the transfer objects 100 of different lengths and weights.

[0048] The locking mechanism 3 includes a threaded connector 31, and the threaded connector 31 is used to connect the transfer pallet 2 and the fork 1, so that the locking mechanism 3 reaches a locking state for fixing the transfer pallet 2 and the fork 1.

[0049] The fork 1 is provided with a plurality of first threaded holes 11, which are arranged at intervals along the length direction of the fork 1; the transfer pallet 2 is correspondingly provided with at least one mounting hole 21, which can be selectively aligned with the plurality of first threaded holes 11. One end of the threaded connector 31 passes through the mounting hole 21 on the transfer pallet 2 and is threadedly connected with the first threaded hole 11 on the fork 1.

[0050] Move the front and rear position of the transfer pallet 2 on the fork 1 along the length direction of the fork 1, and align the mounting hole 21 on the transfer pallet 2 with a first threaded hole 11 on the fork 1; then pass one end of the threaded connector 31 through the mounting hole 21 on the transfer pallet 2 and screw it into the first threaded hole 11 to adjust the position of the transfer pallet 2 on the fork 1 and fix the two. Installation and adjustment are convenient and quick, and fixation is reliable.

[0051] Preferably, the threaded connector 31 is a first screw, and a first handle 32 is provided at the end of the first screw. In this embodiment, the first handle 32 is rotated to drive the first screw to rotate, so that the other end of the first screw passes through the mounting hole 21 on the transfer pallet 2 and is threadedly connected with the first threaded hole 11 on the fork 1.

[0052] like Figures 1 to 3 As shown, the transfer pallet 2 is provided with a sliding sleeve 22 for being sleeved on the fork 1 and slidingly matched with the fork 1 , and the transfer pallet 2 is slidably installed on the fork 1 through the sliding sleeve 22 .

[0053] Optionally, at least two forks 1 are provided, and at least two forks 1 are arranged in parallel; at least two sliding sleeves 22 are provided, and the sliding sleeves 22 and the forks 1 are arranged in one-to-one correspondence.

[0054] Preferably, two sliding sleeves 22 are provided, and the two sliding sleeves 22 are respectively arranged on both sides of the bottom of the transfer pallet 2 , and the two sliding sleeves 22 are correspondingly sleeved on the two forks 1 one by one, so that the transfer pallet 2 can be slidably installed on the forks 1 .

[0055] Preferably, the length of the sliding sleeve 22 is smaller than the length of the fork 1 , and both ends of the fork 1 extend to the openings at both ends of the sliding sleeve 22 , so that the sliding sleeve 22 can move along the length direction of the fork 1 .

[0056] The object to be transferred 100 in this embodiment is cylindrical; the transfer device also includes a limiting mechanism 4 arranged on the transfer tray 2, and the limiting mechanism 4 is used to stop on the outer wall of the object to be transferred 100 to limit the circumferential position of the object to be transferred 100.

[0057] like Figures 1 to 4 As shown, the limiting mechanism 4 in this embodiment includes a positioning member 41 and a driving assembly 42 .

[0058] The driving assembly 42 is installed on the transfer tray 2 and connected to the positioning member 41. The driving assembly 42 is used to drive the positioning member 41 to move in a direction close to or away from the object to be transferred 100. The positioning member 41 is used to stop on the outer wall of the object to be transferred 100.

[0068] like Figure 1 , Figure 2 and Figure 5 As shown, the transfer device also includes a fastening assembly 5 installed on the fork 1, and the fastening assembly 5 is used to adjust the distance between the two forks 1, so that the fork 1 moves slightly in the sleeve on the transfer pallet 2 along the width direction of the fork 1 until the fork 1 stops and fits tightly against the inner wall of the sliding sleeve 22.

[0069] The fastening assembly 5 includes a third lead screw 51 mounted on the fork 1, and a third handle 52 disposed at one end of the third lead screw 51, and the other end of the third lead screw 51 passes through the second threaded hole 12 on the fork 1 and is connected to the vehicle body. The third handle 52 is rotated to drive the third lead screw 51 to screw into the vehicle body, and the fork 1 is driven by the third lead screw 51 to move slightly in the sleeve along the width direction of the fork 1 until the fork 1 is tightly fitted on the inner wall of the sliding sleeve 22, and the transport bracket can be firmly installed on the fork 1.
