fig. 2 is a schematic structural diagram of an embodiment of a forklift cantilever structure provided by the present invention.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 2, the present embodiment provides a forklift cantilever structure, including: fork 1, yoke 2 is vertical arranges, fork 1 vertical fixation in the lower extreme of yoke 2, fork truck cantilever structure still include stand 3, cantilever 4.

The utility model discloses a multi-functional fork arm, including fork arm 2, stand 3, connecting axle 2a, cantilever 4, and the one end of cantilever 4 with the upper end fixed connection of stand 3, in this embodiment, cantilever 4 with be fixed with a strengthening rib 5 that the slope was arranged between the stand 3, stand 3 is the vertical pipe of arranging, the coaxial cover of lower extreme of stand 3 is located connecting axle 2a, and the lower terminal surface butt of stand 3 in the up end of connecting axle 2a, stand 3 can be relative connecting axle 2a rotates, cantilever 4 level is arranged.

This fork truck cantilever structure can directly upgrade the improvement on current fork truck, need not to change fork truck again, specifically can be at a connecting axle of the upper end welded fastening of yoke 2, thereby can connect stand 3, when the lower goods in handling position, directly use fork 1 from the goods bottom fork can, when the higher goods in position is piled up in the transport, can use cantilever 4 to insert and locate the goods bottom to use cantilever 4 transport to pile up the higher goods in position.

In the prior art, two fork arms 2 arranged in parallel and two forks 1 arranged in parallel are usually arranged on one forklift, so in this embodiment, two upright posts 3 and two cantilevers 4 are arranged, that is, one cantilever 4 is fixed on one upright post 3.

This embodiment still provides a preferred embodiment, fork truck cantilever structure still include tapered roller bearing, tapered roller bearing's inner circle with the coaxial fixed connection of connecting axle 2a, tapered roller bearing's outer lane with the coaxial fixed connection of stand 3, thereby it is convenient stand 3 is relative connecting axle 2a rotates, when only using fork 1 transport goods, can with cantilever 4 rotates to keeping away from one side of fork 1 avoids cantilever 4 to be located directly over fork 1, avoids causing the upper end of the packing box on the fork 1 to block.

And a chain block (not shown in the figure) is arranged at one end of the cantilever 4 far away from the upright column, and the goods can be hoisted by using the chain block.

In this embodiment, the connecting shaft 2a is provided with four first jacks arranged along a circumferential circumference of the connecting shaft 2a, each of the four first jacks is provided with one first jack a at a front side, a rear side, a left side and a right side of the connecting shaft 2a, the circumferential surface of the upright post 3 is provided with four second jacks b, each of the second jacks b penetrates through an inner circumferential surface and an outer circumferential surface of the upright post 3, the four second jacks b are arranged along the circumferential circumference of the upright post 3 in an array manner, the upright post 3 is rotated to enable the four second jacks b to be coaxial with the four first jacks a one by one, the forklift cantilever structure further comprises a plug pin, the plug pin can be simultaneously inserted into the coaxially arranged first jacks a and the second jacks b, the first jacks a are arranged in a downward-inclined manner, so that the upright post 3 and the connecting shaft 2a can be fixed by using the plug pin, the upright post 3 is prevented from rotating relative to the connecting shaft 2a in the process of carrying goods.
