[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0024] Example

[0025] like Figure 1 、 2 As shown in Figure 3, it includes a transport vehicle 1, an adjusting mechanism 2 is provided at one end of the transport vehicle 1, a lifting mechanism 3 is provided between the transport vehicle 1 and the adjusting mechanism 2, a distance changing mechanism 4 is provided at one end of the adjusting mechanism 2, the adjusting mechanism 2 includes a first connecting joint 201 installed at one end of the transport vehicle 1, a second connecting joint 202 is provided at one end of the first connecting joint 201, support arms 203 are provided on both sides of the first connecting joint 201, and the first connecting joint 201 is rotatably connected to the support arm 203, an adjusting arm 204 is provided on the outside of the first connecting joint 201, and the top of the adjusting arm 204 is provided on the inner side of the support arm 203 and is rotatably connected to the support arm 203.

[0026] It should be noted that, in this embodiment, when the fork arm angle needs to be adjusted, the first driving cylinder 205 starts to work, and the extension and retraction action of the first driving cylinder 205 drives the first connecting joint 201 to move, and the first connecting joint 201 drives the second connecting joint 202 to move. Since the first connecting joint 201 is rotatably connected to the support arm 203, and the top of the adjustment arm 204 is arranged on the inner side of the support arm 203 and is rotatably connected to the support arm 203, the adjustment arm 204 is driven by the first connecting joint 201 to rotate around the connection point with the support arm 203, thereby adjusting the angle of the adjustment arm 204 and thus changing the angle of the fork arm.

[0027] Among them, Figure 4As shown, the lifting mechanism 3 includes a lifting frame 301 installed at one end of the transport vehicle 1, and side grooves 302 are provided on both sides of the lifting frame 301. The inner wall of the side grooves 302 is provided with a second driving cylinder 303. When adjusting the height of the load-bearing arm 404, the second driving cylinders 303 on both sides of the lifting frame 301 are started, and the slide plate 207 slides up and down along the lifting frame 301 under the push of the second driving cylinder 303. Since a support arm 203 is provided on the top of the mounting frame 206, and the support arm 203 is connected to the adjustment arm 204, the movement of the slide plate 207 drives the movement of the entire adjustment mechanism 2 and the distance changing mechanism 4, thereby realizing the adjustment of the angle and height of the load-bearing arm 404.

[0028] like Figure 5 As shown, the pitch changing mechanism 4 includes a connecting plate 401 installed at the end of the adjusting arm 204, the end wall of the connecting plate 401 is provided with a two-way telescopic cylinder 402, side plates 403 are provided on both sides of the connecting plate 401, and a load-bearing arm 404 is provided on the outer side of the connecting plate 401, and the connecting plate 401 is slidably connected to the load-bearing arm 404.

[0029] It should be noted that, in this embodiment, when the spacing between the load-bearing arms 404 needs to be adjusted, the two-way telescopic cylinder 402 is started. The two-way telescopic cylinder 402 is installed on the end wall of the connecting plate 401, and its two sides are fixedly connected to the load-bearing arms 404. When the two-way telescopic cylinder 402 is extended or retracted, it pushes the load-bearing arms 404 to slide on the outside of the connecting plate 401, thereby changing the spacing between the load-bearing arms 404 to adapt to the handling requirements of goods of different sizes, and the side plates 403 are used to limit the load-bearing arms 404.

[0030] Working principle of this utility model:

[0031] Refer to the instruction manual Figure 1-5 First, adjust the fork arm height and activate the second drive cylinders 303 on both sides of the lifting frame 301. Driven by the second drive cylinders 303, the slide 207 slides up and down along the lifting frame 301, and the slide 207 drives the mounting frame 206 and the support arm 203 to move;

[0032] Then the first driving cylinder 205 starts to work. The extension and retraction of the first driving cylinder 205 drives the first connecting joint 201 to move, and the first connecting joint 201 drives the second connecting joint 202 to move. Since the first connecting joint 201 is rotatably connected to the support arm 203, and the top of the adjustment arm 204 is arranged on the inner side of the support arm 203 and is rotatably connected to the support arm 203, the adjustment arm 204 is driven by the first connecting joint 201 to rotate around the connection point with the support arm 203, thereby adjusting the angle of the adjustment arm 204 and thus changing the angle of the fork arm.

[0033] Finally, the bidirectional telescopic cylinder 402 installed in the connecting plate 401 drives the movement of the load-bearing arm 404, so that the load-bearing arm 404 slides on the outside of the connecting plate 401, thereby changing the distance between the load-bearing arms 404 to adapt to the handling needs of goods of different sizes, and the side plate 403 is used to limit the load-bearing arm 404.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
