[0054] Now, refer to the appendix Figure 1 To the attached Figure 8 Exemplary embodiments according to the present invention will be described in more detail below.

[0055] This application provides a container transfer device 100, with reference to... Figure 1 , Figure 4 and Figure 5The container transfer device 100 includes a support beam 110, a wheel set 150, a pull-out beam 130, and a twist-lock mechanism 140. The support beam 110 has opposite first ends 101 and second ends 102, and has a cavity extending from the first end 101 to the second end 102. The wheel set 150 is located at the bottom of the support beam 110. Two pull-out beams 130 extend from the first end 101 and the second end 102 into the cavity, respectively, and are telescopically movable relative to the support beam 110. The twist-lock mechanism 140 is located on the upper side of the end of the pull-out beam 130 away from the support beam 110, and is used to engage with the bottom corner fittings 11 of the container 10.

[0056] The container transfer device 100 according to this utility model can freely adjust its width to adapt to the transfer of containers of different models and sizes.

[0057] For the specific structure of support beam 110, please refer to Figure 2 , Figure 6 and Figure 7 The support beam 110 includes a main frame 111 and a wheel seat frame 115. A retractable beam 130 is telescopically mounted on the main frame 111, and two wheel seat frames 115 are respectively mounted at both ends of the main frame 111. The wheel set 150 includes a wheel body and a wheel axle that passes through the wheel body. The wheel axle passes through the wheel seat frame 115 in a direction from the first end 101 to the second end 102.

[0058] The first end 101 and the second end 102 of the support beam 110 have upward-facing notches 112, so that when the pull-out beam 130 is retracted into the support beam 110, the torsion locking mechanism 140 is located in the notches 112. More specifically, the cavity extending from the first end 101 to the second end 102 is located in the main frame 111, and the two ends of the main frame 111 have the aforementioned upward-facing notches 112.

[0059] As one implementation, a pad 113 is also provided on the upper side of the main frame 111, adjacent to the opening. This pad 113 serves to provide a certain load-bearing cushioning effect for the container 10. For example, the pad 113 can be a polyurethane pad. As another implementation, a panel 114 is provided on the inner wall of the end of the main frame 111, thereby allowing the pull-out beam 130 to slide against the panel 114 during movement, preventing direct friction and collision between the pull-out beam 130 and the main frame 111, thus avoiding damage. The panel 114 can be made of a material with a certain lubrication capability, such as a plastic panel or a polyurethane panel.

[0060] In a preferred embodiment, when the pull-out beam 130 is retracted into the support beam 110, the end of the pull-out beam 130 is flush with the end of the support beam 110. In other words, the pull-out beam 130 can be completely retracted into the main frame 111 of the support beam 110 without protruding from the main frame 111.

[0061] refer to Figure 3 and Figure 4 The pull-out beam 130 includes a beam body 131, with a cavity at one end of the beam body 131 opening towards the pull-out direction. A twist-lock mechanism 140 is at least partially disposed within the cavity at the end of the beam body 131. More specifically, the twist-lock mechanism 140 includes a lock body 141, an operating member 142, and a fixing assembly 143. The lock body 141 is at least partially located within the cavity and extends vertically through the pull-out beam 130. The operating member 142 is connected to the lock body 141 and extends outward from the opening of the cavity. The fixing assembly 143 is disposed between the lock body 141 and the operating member 142, connecting them to secure the lock body 141 and the operating member 142. Exemplarily, the fixing assembly 143 may include a pin and a cotter pin.

[0062] As an example, the pull-out beam 130 also includes a base 132 and a mounting seat 133. The base 132 is disposed on the upper side of the end of the beam 131, and the mounting seat 133 extends through the base 132 and the beam 131. The mounting seat 133 has a vertically penetrating channel through which the lock body 141 extends out of the beam 131. The base 132 may be made of polyurethane board.

[0063] refer to Figure 1 , Figure 2 and Figure 6 The wheel seat frame 115 includes an upright plate 116, at least one first reinforcing plate 118, and at least one pair of second reinforcing plates 119. The two upright plates 116 are spaced apart, and each upright plate 116 has a bearing groove 117, in which the main frame 111 is disposed. The first reinforcing plates 118 connect the two upright plates 116. Preferably, each wheel seat frame 115 has two first reinforcing plates 118, which are spaced vertically apart. The second reinforcing plates 119 are vertically disposed on the upright plates 116, and the two second reinforcing plates 119 on the two upright plates 116 protrude from the upright plates 116 in a direction away from each other. As shown in the figure, each upright plate 116 can have two pairs of second reinforcing plates 119; in other words, a wheel seat frame 115 can have two pairs of second reinforcing plates 119.

[0064] As an alternative implementation, each upright plate 116 has two wheel grooves 120 at its bottom, and each wheel seat 115 is provided with two sets of wheels 150, with the axles of the two sets of wheels 150 disposed in the wheel grooves 120.
