The current measurement method is to use a forklift to transport the goods to the scale for weighing and measurement, and then use a forklift to transport the goods to the storage shelves or designated areas or to load them into the logistics vehicle.
[0003] Application number 2020104920893 discloses the scale structure of a weighing and metering forklift scale specially used for motor forklifts. Four side fixed strain beams are symmetrically installed on both sides of the rear mounting plate and the front mounting plate which are parallel to each other. The load-bearing fixed block installed on the front mounting plate is embedded in the side fixed strain beam. Fixing screws are installed through the upper part of the rear mounting plate and the front mounting plate, and joint bearings are installed on the fixing screws. A tension sensor is suspended on the joint bearing. The bottom of the tension sensor is connected to the load-bearing screw, and the load-bearing screw is installed on the load-bearing fixed block. The upper fixed block of the fork frame and the lower fixed block of the fork frame are installed on the rear mounting plate, forming the scale structure as a whole.
[0004] Although the above patent solves the problem of weighing and metering to a certain extent, the patent relies solely on a tension sensor to weigh the placed goods, which may cause weighing errors due to the deviation of the weighed goods from the center of placement.

[0028] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.
[0029] Embodiment 1:
[0030] like Figure 1 As shown, a weighing and metering scale structure for a motor forklift includes: a pair of forklift connectors 10, a forklift mounting block 20 for mounting the forklift connector 10, a weighing and adjusting device 30 installed in the forklift mounting block 20, a fork mounting block 40 installed on the weighing and adjusting device 30, and a strain device 50 installed on both sides of the fork mounting block 40 and the forklift mounting block 20.
[0031] The scale structure is installed on a motor forklift through a pair of forklift connectors 10, and the fork is installed on the fork mounting block 40; when the goods are placed on the fork, the pressure generated by the weight of the goods will be transmitted to the fork mounting block 40 through the fork, converted into the pulling force of the fork mounting block 40, and then transmitted to the weighing and adjusting device 30 through the fork mounting block 40, and the obtained weight will be fed back to the display terminal through the weighing and adjusting device 30.
[0032] During the above-mentioned measurement process, the weighing adjustment device 30 has an adjustment function, which can keep the weighing adjustment device 30 perpendicular to the pulling force generated by gravity at all times, thereby preventing errors from occurring during the measurement process and improving the measurement accuracy.
[0033] Strain devices 50 are installed on both sides of the fork mounting block 40 and the forklift mounting block 20. The strain devices 50 cover the sides of the fork mounting block 40 and the forklift mounting block 20, which can effectively prevent the fork mounting block 40 from deviating to the left or right due to the gravity inertia when the goods are placed on the forks, thereby further improving the measurement accuracy.
[0034] Under the strain device 50 , when the goods are removed from the fork, the fork mounting block 40 and the weighing adjustment device 30 are reset under the rebound force of the strain device 50 .
[0035] like Figure 2 As shown, the forklift mounting block 20 includes a rear mounting plate 21, two rear connecting members 22 mounted on the rear mounting plate 21, an upper connecting block 23 disposed between the two rear connecting members 22, and a lower connecting block 24 disposed under the upper connecting block 23.
[0036] The forklift mounting block 20 is mounted on a motor forklift through the rear mounting plate 21 .
[0037] The upper connecting block 23 and the lower connecting block 24 are both arranged between the two rear connecting members 22; the forklift mounting block 20 is connected to the weighing and adjusting device 30 through the upper connecting block 23 and the lower connecting block 24; the upper connecting block 23 is fixedly connected to the weighing and adjusting device 30, and the lower connecting block 24 is movably connected to the weighing and adjusting device 30.
[0038] The rear connecting piece 22 is used to connect the strain device 50 .
[0039] like Figure 3 As shown, the weighing and adjusting device 30 includes an upper corrector 31, an upper bearing screw 32 installed on the upper corrector 31, a gravity sensor 33 installed on the upper bearing screw 32, a lower bearing screw 34 installed on the gravity sensor 33, a lower corrector 35 installed on the lower bearing screw 34, and a force-bearing shaft 36 installed on the lower corrector 35.
[0040] The weighing and adjusting device 30 is fixed to the upper connecting block 23 via an upper corrector 31 , is movably connected to the lower connecting block 24 via a lower corrector 35 , and is fixedly connected to the fork mounting block 40 via a force bearing shaft 36 .
[0041] The weight of the cargo passes the gravity to the fork mounting block 40 through the fork, and the gravity is converted into the pulling force of the fork mounting block 40, and the pulling force is transmitted to the force-bearing shaft 36 connected to the fork mounting block 40 through the fork mounting block 40, and the force-bearing shaft 36 is transmitted to the gravity sensor 33 through the lower corrector 35 and the lower bearing screw 34, and the weight information is generated by the gravity sensor 33, and the weight information is fed back to the display terminal.
[0042] When the cargo is placed on the forks, it will deviate left and right due to the inertia of the cargo. The gravity sensor 33, under the joint action of the upper corrector 31 and the lower corrector 35, ensures that the pulling force is always perpendicular to the gravity sensor 33, thereby avoiding measurement errors caused by the pulling force not being perpendicular to the gravity sensor 33 due to the deviation.
[0043] like Figure 4 As shown, the upper corrector 31 includes an upper outer ring 311, an upper inner ring 312 arranged in the upper outer ring 311, an upper movable ball 313 arranged in the upper inner ring 312, and an upper connecting rod 314 arranged in the upper movable ball 313; the lower corrector 35 includes a lower outer ring 351, a lower inner ring 352 arranged in the lower outer ring 351, a lower movable ball 353 arranged in the lower inner ring 352, a lower connecting rod 354 arranged in the lower movable ball 353, and an adjusting lever 355 installed on the lower connecting rod 354; the lower connecting rod 355 is provided with a force-bearing hole 356.
[0044] The upper corrector 31 is fixedly connected to the upper connecting block 23 via the upper connecting rod 314 .
[0045] The lower corrector 35 is rotatably connected to the lower connecting block 24 via the adjusting lever 355. The adjusting lever 355 can rotate on the lower connecting block 24 to adjust the gravity sensor 33, find the best force point of the gravity sensor 33, and improve the measurement accuracy of the scale structure.
[0046] The force bearing shaft 36 is connected to the lower connecting rod 354 by being inserted into the force bearing hole 356 .
[0047] The upper movable ball 313 can rotate in the upper inner ring 312 .
[0048] The lower movable ball 353 can rotate in the lower inner ring 352 .
[0049] When the tension of the cargo is offset due to inertia, the weighing and adjusting device 30 moves on the upper movable ball 313 through the upper inner ring 312, and the lower inner ring 352 moves on the lower movable ball 353, so as to adjust the gravity sensor 33 arranged between the upper corrector 31 and the lower corrector 35 in the force direction, so that the tension generated by the cargo always remains perpendicular to the gravity sensor 33, thereby avoiding measurement errors.
[0050] When the fork mounting block 40 is subjected to tension, the tension is transmitted to the lower corrector 35 through the force-bearing shaft 36, and then transmitted to the lower load-bearing screw 34. If the tension and the lower load-bearing screw 34 are no longer in a straight line at this time, under the action of the tension, the lower corrector 35 will move on the lower movable ball 353 through the lower inner ring 352, and at the same time, the upper corrector 31 will move on the upper movable ball 313 through the upper inner ring 312. The lower corrector 35 and the upper corrector 31 are adjusted together to make the tension and the lower load-bearing screw 34 in a straight line, ensuring that the tension is always perpendicular to the gravity sensor 33; when the tension is transmitted to the gravity sensor 33, the gravity sensor 33 generates weight information and feeds it back to the display terminal.
[0051] like Figure 5 As shown, the fork mounting block 40 includes a front mounting plate 41 , two front connecting members 42 mounted on the front mounting plate 41 , and fixing holes 43 formed on the front connecting members 42 .
[0052] The fork mounting block 40 is connected to the fork through a front mounting plate 41 .
[0053] The fork mounting block 40 is connected to the strain device 50 via a front connecting piece 42 .
[0054] The force bearing shaft 36 is connected to the front connecting member 42 by being inserted into the fixing hole 43 .
[0055] like Figure 6 As shown, the strain device 50 includes a left strain beam 51 , a right strain beam 52 arranged on the right side of the left strain beam 51 , and a plurality of strain knots 53 arranged between the right strain beam 52 and the left strain beam 51 .
[0056] The strain device 50 is connected to the rear connecting member 22 through the left strain beam 51, and to the front connecting member 42 through the right strain beam 52; the left strain beam 51 and the rear connecting member 22 have the same shape and size, and the right strain beam 52 and the front connecting member 42 have the same shape and size. Such a design can prevent the strain device 50 from being deformed due to excessive inertia force when the goods are placed.
[0057] The strain knot 53 connects the left strain beam 51 and the right strain beam 52; the strain knot 53 moves downward and deforms under gravity, and can recover the deformation under no gravity. Therefore, after the goods are removed, the weighing adjustment device 30 and the fork mounting block 40 return to their original positions under the rebound force of the strain knot 53, and the next weighing of the goods can be carried out.
[0058] The number of the strain knots 53 can be determined according to actual needs. In this embodiment, there are four strain knots 53. By increasing the number of strain knots 53, it is possible to prevent the strain knots 53 from breaking during use and thus preventing the metering function from being unable to be realized, thereby increasing the service life of the scale structure.
[0059] like Figure 7 As shown, the strain junction 53 includes a strain bar 531 and strain holes 532 opened on both sides of the strain bar 531 .
[0060] The strain knot 53 is connected to the left strain beam 51 and the right strain beam 52 through the strain bar 531, and the deformation and rebound ability of the strain bar 531 is used to achieve the reset of the weighing adjustment device 30 and the fork mounting block 40, and to perform the next weighing.
[0061] Strain holes 532 are disposed on both sides of the strain bar 531 , and the strain holes 532 can provide deformation space for the strain bar 531 .
[0062] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the attached claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention. Any figure mark in the claims should not be regarded as limiting the claims involved.
