[0051] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0052] like Figures 1 to 5 As shown, an embodiment of the utility model provides a tilting fork 305 frame for a forward moving vehicle, comprising: a mounting frame 1; two forks 305 are provided, and the two forks 305 are provided on the mounting frame 1 to support goods; a limiting portion is provided on the mounting frame 1 and cooperates with the forks 305 to prevent the goods from tipping over; a first adjusting portion is provided on the mounting frame 1 and is rotatably connected to the forks 305 to adjust the positions of the two forks 305; a second adjusting portion is provided on the mounting frame 1 and is slidably connected to the forks 305 to adjust the tilt angle of the forks 305.

[0053] In the embodiment of the utility model, the mounting frame 1 is connected to the forklift, and a limit portion is provided on the mounting frame 1 to limit the left and right directions of the cargo on the fork 305 to prevent the cargo from tipping over when the forklift moves; a first adjustment portion is provided to adjust the distance between the two forks 305 to accommodate cargo of different sizes; and a second adjustment portion is provided to adjust the angle of the fork 305 to accommodate the unstable center of gravity of uneven cargo during transportation.

[0054] like Figures 1 to 5 As shown, the limiting part includes: a first bidirectional threaded rod 201, both ends of which are rotatably connected to the inner wall of the mounting frame 1; a first motor 202, which is arranged on the mounting frame 1, and the output end is fixedly connected to one end of the first bidirectional threaded rod 201; a first limiting component, which is provided with two groups, and the two groups of the first limiting components are symmetrically arranged on the first bidirectional threaded rod 201.

[0055] In the embodiment of the utility model, the first motor 202 is started to drive the first bidirectional threaded rod 201 to rotate, thereby driving the two first limit assemblies to move toward each other along the first bidirectional threaded rod 201 .

[0056] Among them, the bidirectional threaded rod, that is, the thread directions on both sides are different, and the threaded sleeves with different thread directions will move in opposite directions along the bidirectional threaded rod.

[0057] like Figures 1 to 5 As shown, the first limiting assembly includes: a first threaded sleeve 203, which is sleeved on the first bidirectional threaded rod 201; a connecting plate 204, which is arranged on the first threaded sleeve 203; a movable groove 205, which is opened on the connecting plate 204; a second threaded rod 207, both ends of which are rotatably connected to the inner wall of the movable groove 205; a second motor 206, which is arranged on the connecting plate 204 and the output end is connected to the second threaded rod 207; a second threaded sleeve 209, which is sleeved on the second threaded rod 207; and a first limiting plate 208, which is arranged on the second threaded sleeve 209.

[0058] In the embodiment of the utility model, when the cargo is forked onto the cargo fork 305, the first motor 202 is started to drive the first bidirectional threaded rod 201 to rotate, thereby driving the two first threaded sleeves 203 to move toward each other along the first bidirectional threaded rod 201, thereby driving the two connecting plates 204 to approach each other, and the movement of the connecting plate 204 drives the second threaded rod 207 and the second threaded sleeve 209 to move, thereby driving the two first limit plates 208 to approach the cargo, thereby achieving preliminary adjustment of the distance between the two first limit plates 208.

[0059] When the cargo is irregular in shape, the first limiting plate 208 at one end abuts against the cargo, while the first limiting plate 208 at the other end has not yet touched the cargo, the second motor 206 of the first limiting plate 208 that has not touched the cargo is started to drive the second threaded rod 207 to rotate, and the second threaded rod 207 drives the second threaded sleeve 209 to move inward along the second threaded rod 207, thereby driving the first limiting plate 208 to move toward the direction close to the cargo until it abuts against the cargo. At this time, the limiting of the asymmetric cargo is completed to prevent the cargo from tipping over to the left or right during transportation.

[0060] Among them, the top of the first threaded sleeve 203 is in contact with the installation frame 1 to prevent the first bidirectional threaded rod 201 from rotating and driving the first threaded sleeve 203 to rotate together; when processing narrower goods, when the two sets of connecting plates 204 move to the position where the two connecting plates 204 are in contact with each other, the two first limiting plates 208 cannot contact the goods. At this time, by starting the two second motors 206, the second threaded rod 207 is driven to rotate, and the second threaded rod 207 drives the second threaded sleeve 209 to move inward along the second threaded rod 207, thereby driving the first limiting plate 208 to move in the direction close to the goods until both sides are in contact with the goods, thereby achieving the limitation of the narrower goods and increasing the width range of the goods that can be transported by the device.

[0061] like Figures 1 to 5 As shown, the first adjusting part includes: a third bidirectional threaded rod 301, both ends of which are rotatably connected to the inner wall of the mounting frame 1; a third motor 303, which is arranged on the mounting frame 1, and the output end is fixedly connected to one end of the third bidirectional threaded rod 301; a third threaded sleeve 302, which is sleeved on the third bidirectional threaded rod 301; a first fixed block 304, which is arranged on the third threaded sleeve 302 and is rotatably connected to the fork 305.

[0062] In the embodiment of the utility model, the third motor 303 is started to drive the third bidirectional threaded rod 301 to rotate, thereby driving the two third threaded sleeves 302 to move relative to each other, and the third threaded sleeves 302 drive the first fixed block 304 to move left and right, thereby driving the fork 305 to move left and right, thereby adjusting the distance between the two forks 305 to accommodate goods of different sizes.

[0063] Among them, a second limit plate 306 is set to fit the third threaded sleeve 302 to prevent the third threaded sleeve 302 from rotating when the third bidirectional threaded rod 301 rotates. A protective shell 101 is set to cover the first motor 202 and the third motor 303 to prevent the motors from being damaged by external force collision.

[0064] like Figures 1 to 5 As shown, the second adjustment part includes: a first fixing plate 401, which is arranged on the installation frame 1; a first cylinder 402, which is arranged on the first fixing plate 401; an extrusion plate 405, which is connected to the fork 305 via a connecting component; a second fixing block 407, which is rotatably connected to the output end of the first cylinder 402 and is arranged on the extrusion plate 405; and a stabilizing component, which is arranged on the first fixing plate 401.

[0065] In the embodiment of the utility model, the first cylinder 402 is started to drive the second fixed block 407 to move forward, thereby driving the extrusion plate 405 to move forward, and the extrusion plate 405 pushes the fork 305 to move forward, so that one end of the fork 305 rotates along the first fixed block 304, so that the angle of the fork 305 changes. When placing goods on the fork 305, the center of gravity of the goods is brought close to the installation frame 1 by adjusting the angle of the fork 305, so as to avoid the situation in which the goods tip forward when the forklift encounters an emergency and needs to brake suddenly during transportation.

[0066] like Figures 1 to 5 As shown, the stabilizing assembly includes: a first telescopic rod 403 , one end of which is connected to the first fixing plate 401 ; a third fixing block 408 , which is rotatably connected to the other end of the first telescopic rod 403 and is disposed on the extrusion plate 405 .

[0067] In the embodiment of the utility model, when the first cylinder 402 pushes the extrusion plate 405 to move forward through the first fixed block 304, the third fixed block 408 moves forward with the extrusion plate 405, thereby driving the first telescopic rod 403 to extend, so that the first telescopic rod 403 limits the movement of the extrusion plate 405.

[0068] When the fork 305 rotates, the extrusion plate 405 rotates with the fork 305 at a certain angle, thereby driving the first fixed block 304 and the first cylinder 402 to rotate, and the third fixed block 408 and the first telescopic rod 403 to rotate.

[0069] like Figures 1 to 5 As shown, the connecting assembly includes: a sliding groove 404 , which is opened on the extrusion plate 405 ; and a sliding block 406 , which is disposed on the fork 305 and slides in the sliding groove 404 .

[0070] In the embodiment of the utility model, by setting the sliding groove 404 and the sliding block 406 to be convex, the sliding block 406 can slide in the sliding groove 404 and cannot be separated from the sliding groove 404. The sliding block 406 is connected to the fork 305, so that when the fork 305 moves left and right, it will be restricted by the sliding groove 404, thereby ensuring the stability of the fork 305 when moving.

[0071] Working principle: First, start the third motor 303 to drive the third bidirectional threaded rod 301 to rotate, thereby driving the two third threaded sleeves 302 to move relative to each other, and the third threaded sleeves 302 drive the first fixed block 304 to move left and right, thereby driving the fork 305 to move left and right, thereby adjusting the distance between the two forks 305 to accommodate goods of different sizes.

[0072] Then fork the cargo onto the cargo fork 305, start the first motor 202, drive the first bidirectional threaded rod 201 to rotate, thereby drive the two first threaded sleeves 203 to move toward each other along the first bidirectional threaded rod 201, thereby drive the two connecting plates 204 to approach each other, and the movement of the connecting plate 204 drives the second threaded rod 207 and the second threaded sleeve 209 to move, thereby drive the two first limit plates 208 to approach the cargo, thereby realizing the preliminary adjustment of the distance between the two first limit plates 208.

[0073] When the cargo is irregular in shape, the first limiting plate 208 at one end abuts against the cargo, while the first limiting plate 208 at the other end has not yet touched the cargo, the second motor 206 of the first limiting plate 208 that has not touched the cargo is started to drive the second threaded rod 207 to rotate, and the second threaded rod 207 drives the second threaded sleeve 209 to move inward along the second threaded rod 207, thereby driving the first limiting plate 208 to move toward the direction close to the cargo until it abuts against the cargo. At this time, the limiting of the asymmetric cargo is completed to prevent the cargo from tipping over to the left or right during transportation.

[0074] Finally, the first cylinder 402 is started to drive the second fixed block 407 to move forward, thereby driving the extrusion plate 405 to move forward, and the extrusion plate 405 pushes the fork 305 to move forward, so that one end of the fork 305 rotates along the first fixed block 304, so that the angle of the fork 305 changes. When placing goods on the fork 305, by adjusting the angle of the fork 305, the center of gravity of the goods is close to the installation frame 1, so as to avoid the situation that the goods fall forward when the forklift encounters an emergency and needs to brake suddenly during transportation. In this way, the restriction of the entire goods is completed, and the stability of the goods transportation is ensured.

[0075] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
