[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figure 1-4 The present embodiment provides a technical solution: an automatic adjustment structure for the fork tip length of an unmanned forklift, comprising a fork handle 1, a sliding arm 3 is installed on the inner side of the horizontal part of the lower part of the fork handle 1, a limiting protrusion 9 is integrally formed on the outer side of the sliding arm 3, a limiting groove 10 is integrally formed at the position corresponding to the limiting protrusion 9 inside the horizontal part of the lower part of the fork handle 1, a supporting roller 11 is installed on the bottom side of the limiting groove 10, a No. 2 electric push rod 8 is installed at one end of the sliding arm 3, a limiting hook 4 is installed at the end of the sliding arm 3 away from the No. 2 electric push rod 8, a side surface of the limiting hook 4 is integrally formed with an anti-slip protrusion 5, the lower end of the limiting hook 4 is movably connected to the No. 1 electric push rod 6, and a center shaft 7 is passed through the center of the limiting hook 4.
[0022] like Figure 1-4 As shown, the No. 1 electric push rod 6 drives the limit hook 4 to rotate around the central axis 7. When it is needed, the limit hook 4 is stored in the slot at the end of the sliding arm 3. When in use, the No. 1 electric push rod 6 pushes the lower end of the limit hook 4 to rotate, so that the limit hook 4 rotates to a vertical state, so that the anti-slip protrusion 5 on the limit hook 4 can be pressed against the side of the cargo support frame, so that the cargo is clamped and fixed. When transporting larger cargo, the No. 2 electric push rod 8 can push the sliding arm 3 to move laterally along the inner side of the limit slot 10, so that the overall length of the fork handle 1 is adjusted, so that the length of the fork tip meets the usage requirements.
[0023] A mounting groove 12 is integrally formed in the fork handle 1 at a position corresponding to the end of the second electric push rod 8 , and a bolt hole 13 is provided in the mounting groove 12 .
[0024] like Figure 1 , 2 As shown in FIG. 4 , the mounting groove 12 can be used to mount and fix one end of the No. 2 electric push rod 8 , thereby providing stable support for the end of the No. 2 electric push rod 8 .
[0025] A supporting sleeve 2 is symmetrically arranged on the upper part of the fork handle 1, and the limit hook 4 is connected with the sliding arm 3 through the central shaft 7 and the No. 1 electric push rod 6.
[0026] like Figure 1-4As shown, the structure of the support sleeve 2 and the upper end of the fork handle 1 allows the fork handle 1 to be stably connected to the transverse axis on the unmanned forklift, and the No. 1 electric push rod 6 can push the limit hook 4 to rotate around the central axis 7, so that the limit hook 4 can limit and clamp the cargo support frame.
[0027] Both ends of the support roller 11 are connected to the fork handle 1 through bearings, and the sliding arm 3 is connected to the fork handle 1 through a No. 2 electric push rod 8.
[0028] like Figure 1-4 As shown, the support rollers 11 can provide rolling support for the limiting protrusions 9 on both sides of the sliding arm 3, ensuring that the sliding arm 3 moves more smoothly and stably during horizontal telescopic movement.
[0029] The upper end of the No. 1 electric push rod 6 is movably connected to the fork handle 1 , and the No. 2 electric push rod 8 is fixedly connected to the inner side surface of the installation groove 12 .
[0030] The other end of the No. 1 electric push rod 6 is fixedly connected to the side of the sliding arm 3, and the central shaft 7 is connected to the limit hook 4 through a bearing.
[0031] The supporting sleeve 2 is fixedly connected to the fork handle 1 .
[0032] The working principle of the automatic adjustment structure for the fork tip length of the unmanned forklift provided by the utility model is as follows: Figure 1-Figure 4 As shown, the upper end of the fork handle 1 and the supporting sleeve 2 can connect the fork handle 1 to the support shaft on the forklift. When the length of the fork tip needs to be extended, the No. 2 electric push rod 8 pushes the sliding arm 3 to move laterally along the limiting groove 10 and the supporting roller 11, so that the sliding arm 3 extends from one end of the fork handle 1, thereby extending the length of the fork tip to meet the usage requirements. When the fork handle 1 forks the cargo support frame, the No. 1 electric push rod 6 drives the limiting hook 4 to rotate around the central axis 7, so that the limiting hook 4 rotates from the groove at the end of the sliding arm 3 to a vertical state, thereby limiting and clamping the cargo support frame to reduce the risk of the cargo slipping off the fork handle 1.
[0033] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
