Referring to fig. 1, fig. 1 is a schematic view of a forklift truck according to an embodiment of the present invention.

The forklift includes a forklift frame 11, a first fork and an auxiliary stabilizing assembly. The first fork is connected to the fork frame 11. The first fork includes two

first sub-forks

12A and 12B whose spacing is adjustable. The bottom surfaces of the two

first sub-forks

12A and 12B are provided with roller assemblies to facilitate movement of the forklift. The

first sub-forks

12A and 12B can be pitch-adjusted by the pitch adjustment unit 15, for example. The distance adjusting unit 15 has a through groove, the

first sub-forks

12A and 12B have a protrusion which fits with the groove, and the distance adjustment of the

first sub-forks

12A and 12B can be achieved by the sliding movement of the protrusion in the through groove. Further, a stopper may be further provided in the groove to limit the

first sub-forks

12A and 12B at the adjusted position.

Each of the

first sub-forks

12A and 12B includes extensions 121 extending oppositely. By adjusting the spacing between the two

first sub-forks

12A and 12B, the turnaround container 20 is located between the two

first sub-forks

12A and 12B, and the two extensions 121 support the bottom of the turnaround container 20. In some embodiments, the thickness of the extension 121 may taper from the end of the fork connected to the fork frame 11 to the end remote from the fork frame 11, thereby to facilitate a lower slope for insertion of the extension 121 into the bottom of the epicyclic receptacle 20, the epicyclic receptacle 20 being movable on the extension 121 from the end remote from the fork frame 11 towards the fork frame 11. In some embodiments, the thickness of the extension 121 may taper from the end of the fork connected to the fork frame 11 to the end away from the fork frame 11, thereby reducing the resistance of the extension 121 to insertion into the bottom of the epicyclic container 20 while ensuring the support force provided by the extension 121 to the epicyclic container 20.

A secondary stabilising assembly is connected to the forklift frame 11 to provide a secondary support force to the epicyclic container 20. In particular, the auxiliary stabilizing assembly may comprise a first auxiliary stabilizing unit providing an auxiliary supporting force against the direction of gravity to the top of the epicyclic container 20 at the end of the epicyclic container 20 facing away from the first forks. For example, a first auxiliary stabilizing unit may comprise a hook 14, the hook 14 being configured to lift a handle 21 of the epicyclic vessel 20 to provide a pulling force to the epicyclic vessel 20 away from the direction of gravity. The handle 21 of the transfer container 20 may be a hole in the sidewall of the transfer container 20 for a person to grasp and transport. The handle 21 of the circulation container 20 may be a grip ring provided on a side wall of the circulation container 20, and may be held by a person for transportation. Thus, the hooks 14 and handles 21 may cooperate to provide additional support against the direction of gravity to the top of the epicyclic receptacle 20. Further, the position and height of the hook 14 may be adjusted to accommodate handles 21 arranged in different positions, and the hook 14 may be aligned with the handle 21 and, when tensioned, may provide a pulling force on the epicyclic receptacle 20 away from the direction of gravity.

In this embodiment, the forklift may further include a second fork 13. The second fork 13 is connected to the fork frame 11 opposite the first fork. The second fork 13 comprises two second sub-forks with adjustable spacing. The second sub-forks can be distance-adjusted, for example, by means of the distance adjustment unit 16. The distance adjusting unit 16 has a through groove, the second sub-fork has a convex part matched with the groove, and the distance adjustment of the second sub-fork can be realized through the sliding of the convex part in the through groove. Further, a limiting piece can be arranged in the groove to limit the second sub pallet fork at the adjusted position.

Further, the second fork 13 is liftably connected to the fork frame 11. In the present embodiment, the

pitch adjusting units

15 and 16 are connected by the elevating unit 17 so that the second forks 13 are elevatably connected to the fork frame 11. In this embodiment, the lifting unit 17 may include an inner sleeve and an outer sleeve, and the lifting adjustment is performed by the relative movement of the inner sleeve and the outer sleeve. Furthermore, the outer sleeve of the lifting unit 17 is further provided with a limiting member to lock the relative positions of the inner sleeve and the outer sleeve. Other lifting units such as lifting chains are also within the scope of the present application. The second forks 13 and the first forks can be adapted to different sizes of transfer containers by means of spacing and lifting fit. Further, the turnover container 20 is limited between the second fork 13 and the first fork, so that the turnover container 20 is prevented from moving in the transportation process, and the stability of the turnover container 20 in the transportation process is improved.

In some embodiments, the lifting and spacing adjustment of the first and second forks may be accomplished by a hydraulic system provided on the forklift. The hydraulic system may include, for example, hydraulic pump motors, hydraulic cylinders, and combination solenoid valves. The operator can command the hydraulic pump motor controller and the solenoid combination valve controller by operating a control device such as a handle or other remote control device, such as fork lift, fork lower, fork spacing adjustment, etc. And a controller of the hydraulic pump motor controls the hydraulic pump motor to output the rotating speed of corresponding action according to different action command inputs so as to control the lifting hydraulic cylinder to control the lifting of the lifting chain. Or the lateral shifting hydraulic cylinder is controlled to realize the distance adjustment of the sub-pallet fork. And the controller of the combined electromagnetic valve controls the opening sizes of the electromagnetic valves at different positions according to different action commands. The lifting chain of the first fork is controlled to lift, and the first fork lifting chain drives the first fork connected to the lifting chain to lift. Similarly, the staff can also send out a second fork spacing adjustment instruction through the operating handle, and the hydraulic pump motor outputs the rotating speed of corresponding action to move the high-pressure oil to the side-shifting hydraulic cylinder of the second fork through a plurality of set solenoid valves, and push the side-shifting hydraulic cylinder of the second fork to move, so as to realize the spacing adjustment of the second fork.

In this embodiment, the hook 14 may be coupled to the bottom of the second fork 13 to be coupled to the fork frame 11 through the second fork 13. Further, the hooks 14 may also be attached at opposite side walls of said second fork 13, so that the two second sub-forks of the second fork 13 may be located on both sides of the turnaround container 20. In some variations, the side of the second fork 13 facing the first fork is provided with a receiving space for receiving the hook 14, so as to facilitate the receiving of the hook 14.

In this embodiment, the supplemental stabilizing assembly may comprise a second supplemental stabilizing unit, which may comprise a bracket 18, the bracket 18 being connected to the forklift frame 11, the bracket 18 comprising a plurality of abutments 181, the abutments 181 being configured to abut the epicyclic vessel 20 to provide support to the epicyclic vessel 20. Further, the contact portion 181 of the bracket 18 is connected to the forklift frame 11 so as to be movable up and down. Specifically, the abutting portion 181 may be lifted and lowered in a structure similar to the lifting unit 17, thereby to accommodate the epicyclic containers of different heights. Further, the cradle rod of the abutting portion 181 can be rotated, and the abutting portion 181 can be connected to the cradle rod through a ball to be universally rotatable, whereby the abutting portion 181 can be further adapted to the different sizes of the epicyclic containers.
