Embodiment Construction
[0029] The full-floating weighing forklift of the present invention includes a car body, a drive unit, a fork frame, a fork hanger, a limit unit, a support assembly for keeping the fork rack and the fork hanger parallel to each other, and a support assembly for measuring the fork frame and the fork rack. Two symmetrically distributed weighing units for the vertical tension between the fork hangers.
[0030] The fork frame is fixedly connected with the driving unit; the fork hanger includes the fork, the upper hanging beam, the lower hanging beam, and the left and right vertical beams for fixing the upper hanging beam and the lower hanging beam; the fork is fixed on the lower hanging beam. In order to ensure the strength, a plurality of reinforcing vertical beams can also be arranged between the left and right vertical beams.
[0031] The supporting assembly includes two left-right symmetrically distributed leaf springs and two left-right symmetrically distributed lower support...

The invention relates to a full floating weighing fork truck, which comprises a body, a driving unit, a yoke, a fork hanger, a supporting assembly for keeping the yoke and the fork hanger mutually parallel, and at least two weighing units for measuring the vertical tension between the yoke and the fork hanger; and the upper ends of the yoke and the fork hanger are connected by using left and right plate springs, and the lower ends of the yoke and the fork hanger are connected with a pressure lever by using left and right dual ball joints or two dual blades, so that a sensor is only sensitive to the component of a force in the vertical direction. The full floating weighing fork truck solves the technical problems of large weighing error, poor weighing consistency and incapability of ensuring the weighing precision and the service life in the conventional weighing fork truck, and has the advantages of high weighing precision, high weighing quantity, long service life and good weighing consistency.
Description
technical field [0001] The invention relates to a forklift, in particular to a forklift capable of realizing accurate weighing. Background technique [0002] When the existing forklift is moving the goods, sometimes it is necessary to know the weight of the goods being moved to record the weight of the goods or to facilitate settlement, such as when the logistics unloads part of the goods from the truck or when the factory mixes multiple materials. [0003] However, the existing forklifts either do not have a weighing function, or the weighing accuracy is not high, because the force point of the fork and the driving mechanism are not completely vertically stressed, but are also affected by horizontal component forces. However, the horizontal component force is not completely consistent in different environments or even in different handling processes, and there is no way to eliminate or compensate it, resulting in large weighing errors and poor weighing consistency. [0004...
