The existing fork carrier is a portal, a shaft and a fork. The fork frame is the main bearing structure of flexible arm fork truck load handling device, and the fork is installed epaxially, and the axle is installed on the portal. The telescopic arm forklift loads and unloads goods through the installation fork, and in the whole loading and unloading process, the portal frame and the fork are always kept relatively static.
Therefore, when the telescopic boom forklift is used for unloading, an operator needs to visually observe whether the goods (or the pallet) fall to the ground or not, and even under more complicated working conditions, auxiliary personnel are needed to convey the information that the goods fall to the ground. When the fork is moved out of the goods (or the pallet), an operator needs to operate the vehicle, and the fork is located between the goods (or the pallet) and the ground, so that friction between the fork and the goods (or the pallet) and the ground needs to be avoided. But if not the experienced old worker is handled, or assistance is provided by an assistant, friction is inevitable. Especially when the arm operation is stretched, the operator is far away from the fork, and the position of fork can not accurately be observed to the people's eye, and whole adjustment is difficult to control, and the operation is wasted time and energy, influences the job schedule. In addition, when the existing fork frame is independently placed on the ground, only the bottom surfaces of the forks contact the ground, and the fork frame is likely to tip backwards due to the fact that the gravity center of the fork frame is close to the rear, so that the fork frame is easily damaged to a certain extent.

In the description of the present invention, "a plurality" means two or more unless otherwise specified.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.
Example 1:
as shown in fig. 1, the embodiment of the utility model provides a flexible arm fork truck is with floating fork frame includes portal 1 and fork 3, and portal 1 includes backplate 11, and backplate 11 provides stable support for fork 3. Both sides of the rear baffle plate 11 are provided with side plates 12, the middle of the rear baffle plate is also provided with a first supporting plate 13, the side plates 12 are symmetrically provided with hole grooves 4, the shape of the hole grooves 4 is in an oblong shape, and reinforcing plates 41 used for reinforcing the hole grooves 4 are further arranged in the circumferential direction.
The first supporting plate 13 is provided with a through hole corresponding to the hole groove 4, a cross shaft 2 penetrates through the through hole and the hole groove 4, the cross shaft 2 can float up and down in the hole groove 4, and the floating range is determined by the size of the hole groove 4. When placing portal 1 independent split on subaerial, can realize that 3 bottoms of fork and portal 1 all contact with ground, through a plurality of faces and ground contact, can more stable place subaerial, do not have the potential safety hazard that fork frame took place to overturn.
Referring to fig. 3, the plurality of forks 3 for carrying goods are rotatably connected to the horizontal shaft 2, the end portions of the forks 3 are provided with the lantern rings 31, and the lantern rings 31 are sleeved on the horizontal shaft 2, so that the lantern rings 31 are in clearance fit with the horizontal shaft 2, the forks 3 are rotatably connected to the horizontal shaft 2, lubricant on the horizontal shaft 2 is uniformly distributed on the lantern rings 31, but not limited thereto, and other modes capable of realizing the rotatable connection are also possible.
When fork 3 bears the goods, fork 3 can contact with the backplate of portal 1, and fork 3 can not rotate around cross axle 2 this moment, backplate 11's setting for whole floating fork frame is more firm, more have stability. When the portal 1 in the prior art bears the goods, the weight of the goods completely acts on the fork 3, the stress of the portal 1 is relatively large, but the fork 3 of the embodiment can float in the vertical direction on the portal 1 along with different stresses, the stress of the portal 1 is changed at the moment, and the numerical value is smaller than the weight of all the goods, so that the service life of the portal 1 is prolonged.
Example 2:
on the basis of embodiment 1, this embodiment further includes a second supporting plate 14, and one or more second supporting plates 14 may be provided, and the number selected in this embodiment is 2, and when the transverse shaft 2 floats to the lowest point in the hole slot 4, the second supporting plate 14 may support the transverse shaft 2.
Referring to fig. 2, the two ends of the cross shaft 2, which are located outside the side plates, are provided with shaft sleeves 5, and the shaft sleeves 5 are fixed by matching bolts 7 and nuts 6, so that the axial movement of the cross shaft 2 can be limited to a certain extent.
The utility model discloses a theory of operation does:
referring to fig. 4, when the telescopic forklift 8 loads the goods, the forks 3 are firstly stopped on the ground, and the position of the forks 3 on the mast 1 is a certain position after floating, then after the goods are loaded, the mast 1 is operated by the operator to be lifted, the forks 3 float downwards under the gravity of the operator and the goods, and contact with the back baffle plate 11 when floating to the lowest point of the hole slot 4 and are supported by the back baffle plate 11, and the mast 1 is a stable structure at this time, so that the goods loading and transporting work can be stably completed.
When unloading, the fork 3 falls to the ground first, and after the fork 3 received the perpendicular ascending holding power in ground, the cross axle 2 floated upwards, and portal 1 just no longer received the weight of goods this moment, only received the power that self weight and complete machine gave, and fork 3 then only received ground holding power, no longer received the power that the complete machine gave, consequently avoided the condition of the abominable atress of fork 3 and portal 1.
In the unloading process, an operator can determine whether the fork 3 falls to the ground or not through the stress change transmitted to the whole truck by the gantry 1 without depending on the observation of human eyes or the reminding of auxiliary personnel. At the moment when the goods fall to the ground, the weight of the goods received by the door frame 1 is directly reduced to 0, and an operator can timely and easily sense stress change so as to make a corresponding subsequent instruction.
After completing the unloading task, the operator needs to remove the forks 3 from the bottom of the load. The operator determines whether the forks 3 have left the ground based on the change in force transmitted by the forks 3. In the starting position, the forks 3 are in contact with the ground, and the forks 3 are in a floating position on the mast 1. At the moment, the whole gantry 1 is only stressed by the gravity of the gantry 1, and when an operator lifts the gantry 1, the transverse shaft 2 floats downwards under the influence of the gravity until the transverse shaft is contacted with the lower end of the long circular hole groove 4. At this time, the stress of the gantry 1 is increased, and the fork 3 is about to leave the ground. The operator can execute an instruction to move out of the forks 3 on the basis of this force feedback. Such operation is simple feasible, and efficiency is higher, reduces the upper surface of fork 3 and the bottom friction of goods and the quality problem that brings.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
