[0047] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0048] In the embodiments of the present invention, unless otherwise specified, directional words such as "up, down, top, bottom" are usually used with reference to the directions shown in the drawings or are used to describe the relative positional relationships of components in the vertical, perpendicular or gravity direction.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various implementations can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0050] Figure 1 is a schematic diagram of a fork frame device according to an embodiment of the utility model, Figure 2 It is a side view of a fork frame device according to an embodiment of the utility model. In the figure, the fork frame device includes a fork frame assembly 1, a crossbeam 2 and a fork 3. Among them, the fork frame assembly 1 is used to connect with a forklift. The crossbeam 2 is arranged at the bottom of the fork frame assembly 1 and is fixedly connected to the fork frame assembly 1. The fork 3 is connected to the fork frame assembly 1 and the crossbeam 2, and the relative distance between the forks 3 arranged on both sides of the crossbeam 2 is greater than the relative distance between the left and right legs of the forklift, and when the bottom of the fork 3 is in contact with the ground, the height of the crossbeam 2 is higher than the legs. In the prior art, the width of the fork frame assembly 1 and the crossbeam 2 is narrow and smaller than the distance between the left and right legs of the forklift, and the forklift can only carry a small number of aluminum ingots. The crossbeam 2 moves up and down in a vertical plane, and even if it drops to the same level as the legs, it will not contact and collide with the legs. In order to carry multiple aluminum ingots at the same time and greatly improve work efficiency, the utility model widens the length of the fork frame assembly 1 and the crossbeam 2. The relative distance between the forks 3 on both sides of the crossbeam 2 is greater than the relative distance between the left and right legs of the forklift. The length of the crossbeam 2 is greater than the distance between the legs. When the crossbeam 2 is lowered, it is easy to collide with the legs. In order to avoid this situation, the utility model further raises the fork frame assembly 1 and the crossbeam 2. The height of the crossbeam 2 is higher than the legs. When the bottom of the fork 3 is in contact with the ground, the fork frame assembly 1 and the crossbeam 2 are always raised a certain distance in advance.

[0051] In this embodiment, the specific structure of the fork 3 can be various structures known to those skilled in the art, provided that the fork can pick up the cargo. In one example of the present invention, the fork 3 can include a vertical arm 4 and a horizontal arm 5. Figure 3As shown, the vertical arm 4 is connected to the crossbeam 2 and the fork frame assembly 1, and the horizontal arm 5 is connected to the vertical arm 4. Since the precise control range of the fork 3 up and down movement is limited, the end face of the standard fork 3 may not meet the precise control of the aluminum ingot handling. Considering the special structural dimensions of the aluminum ingot, the bottom of the aluminum ingot presents a step surface shape with a small step height, and the first groove 6 is provided on the opposite side of the horizontal arm 5 of the same set of forks 3. The first groove 6 is effectively fitted with the bottom of the aluminum ingot, positioning the aluminum ingot placed on the fork 3, and improving the control accuracy of the fork 3 picking up the goods.

[0052] In this embodiment, the specific structure of the fork assembly 1 can be various ones known to those skilled in the art. In one example of the present utility model, Figure 4 , Figure 5 and Figure 6 As shown, the fork frame assembly 1 may include a front frame 7 and a rear frame 8. The front frame 7 is connected to the forklift, and the rear frame 8 is arranged on an end of the front frame 7 away from the cross beam 2.

[0053] During the process of transporting aluminum ingots, the fork 3 is prone to shaking and displacement, causing the aluminum ingot to fall off. Therefore, in this embodiment, the fork frame device may further include a limit plate 9. Specifically, Figure 7 As shown in the figure, the limit plate 9 is arranged on the cross beam 2 and located on both sides of the fork 3, and is used to fix the fork 3, and the same limit plate 9 is shared between two adjacent vertical arms 4 of different groups. As for the number of the limit plates 9, under the premise of fixing the fork 3, it can be a plurality known to those skilled in the art. In one example of the present utility model, the number of the limit plates 9 can be 7.

[0054] In this embodiment, the fixing method of the limit plate 9 and the cross beam 2 can be various known to those skilled in the art. In one example of the present utility model, the limit plate 9 and the cross beam 2 can be connected by screws. The limit plate 9 is provided with a first screw hole, and the cross beam 2 is provided with a corresponding second screw hole. The first screw hole and the second screw hole are connected by screws. The limit plate 9 is fixed to the cross beam 2 by screws, and the operation is simple and convenient.

[0055] In this embodiment, the specific structure of the fork frame device can be various known to those skilled in the art. In one example of the present utility model, in order to prevent the aluminum ingot from sliding backward due to the backward tilt of the fork 3, as shown in FIG. Figure 8As shown, the fork frame assembly 1 includes a load sensor bracket 10 and a load sensor 11. The load sensor bracket 10 is arranged at the bottom of the crossbeam 2 and is located on the inner side of the vehicle leg. The bottom of the load sensor bracket 10 is set at the same height as the bottom of the fork 3. The load sensor 11 is arranged on the side of the load sensor bracket 10 away from the forklift and is located at the bottom of the load sensor bracket 10. When the aluminum ingot slides backward due to the backward tilt of the fork 3, the load sensor 11 is installed on the load sensor bracket 10, and the electrical signal received by the load sensor 11 is transmitted to the AGV forklift, so as to quickly control the tilt angle of the fork 3 to avoid the risk of the aluminum ingot sliding backward.

[0056] In this embodiment, the specific structure of the fork frame device can be any known one in the art. Considering the need to monitor the front end of the fork 3 in real time to avoid collision and ensure safe handling, in a preferred example of the present invention, Fig. 9 , Fig.10 and Fig.11 As shown, the fork frame assembly 1 also includes a fork tip sensor bracket 12 and a fork tip sensor 13. The fork tip sensor bracket 12 is arranged on the side of the horizontal arm 5 away from the first groove 6, and is located at the end of the horizontal arm 5 away from the vertical arm 4, and the fork tip sensor 13 is arranged on the fork tip sensor bracket 12. When an obstacle appears in front of the fork 3 during the transportation of aluminum ingots, the fork tip sensor 13 will transmit an electrical signal to the AGV forklift to monitor the front end of the fork 3 according to whether there is an obstacle in front of the fork 3. In addition, in order to protect the fork tip from being damaged by collision with foreign objects, the fork frame assembly 1 also includes a fork tip sensor guard plate 14. The fork tip sensor guard plate 14 is arranged above the fork tip sensor bracket 12, which increases the service life of the fork tip sensor 13.

[0057] On the other hand, the utility model provides a forklift, which includes a forklift body and any one of the fork frame devices described above.

[0058] Through the above technical scheme, the utility model provides a widened fork frame device and a fork, which includes a fork frame assembly, a crossbeam and a fork. The fork frame assembly is used to connect with a forklift. The crossbeam is arranged at the bottom of the fork frame assembly and is fixedly connected to the fork frame assembly. The fork is connected to the fork frame assembly and the crossbeam, and the relative distance between the forks arranged on both sides of the crossbeam is greater than the relative distance between the left and right legs of the forklift, and when the bottom of the fork is in contact with the ground, the height of the crossbeam is higher than the legs. Compared with the prior art, the utility model greatly improves the work efficiency by widening the length of the fork frame assembly and the crossbeam to carry multiple aluminum ingots at the same time, improves the control accuracy of the fork picking up goods by arranging a first groove on the fork, prevents the aluminum ingots from sliding backwards due to the backward tilt of the fork by using a load sensor, and realizes the monitoring of the cargo status and the surrounding environment of the fork by using a fork tip sensor.
