Description of the embodiments

The invention will now be further described by way of specific examples with reference to the accompanying drawings, which are given by way of illustration only and not by way of limitation.

Example 1

1-5, see the accompanying drawings, including fixed plate 1 and floating plate 2, the width of fixed plate 1 and floating plate 2 is unanimous, and is provided with the elastic connection spare 3 that makes them link up at vertical side, and elastic connection spare 3 includes cross piece 31 and sets up the connecting block 32 in cross piece 31 symmetry both sides, connects fixed plate 1 and floating plate 2 respectively for when floating plate 2 receives down force, cross piece 31 that elastic connection spare 3 can produce certain deformation, makes floating plate 2 come down a certain distance.

Wherein, all be provided with the heavy groove 5 that subtracts in fixed plate 1 and floating plate 2's central panel department to alleviateed the weight of whole scale body, reduced fork truck's load burden, and the setting of the heavy groove 5 that subtracts has made things convenient for again that tools such as workman's spanner pass the scale body, directly carries out the maintenance of symmetry body. The upper side of the floating plate 2 is provided with a clamping groove 21, and a plurality of clamping grooves are uniformly distributed at intervals. Therefore, the fork teeth 4 can adjust the width assembled on the floating plate 2, objects with different widths can be conveniently inserted, and the adjustment is convenient and flexible. The back of fixed plate 1 relative floating plate 2 is provided with detains the claw, is provided with fixed claw 61 at the upper side of fixed plate 1, wherein locks through the screw earlier in the assembly, later direct welding, and the lower side board of fixed plate 1 is provided with movable claw 62, can dismantle with fixed plate 1 through the screw and be connected, when the installation is called the body, detains on fork truck's elevating platform through fixed claw 61 earlier, then also locks the lower side of fixed plate 1 with the elevating platform through movable claw 62, realizes comprehensive fixed.

Referring to fig. 3-5, a force measuring structure is provided between the floating plate 2 and the fixed plate 1, one each, symmetrically about the center of the fixed plate 1. The force measuring structure comprises an S-shaped sensor 8, a first upper fixing block 71 is arranged at the upper end of the force measuring structure, the first upper fixing block 71 is horizontally arranged and fixed on a fixing plate 1, one end close to the center of the fixing plate 1 is connected with a second upper fixing block 72 through a second connecting piece 92, the second upper fixing block 72 is fixedly welded on a floating plate 2, one end, far away from the center of the fixing plate 1, of the first upper fixing block 71 is connected with the upper end of the sensor 8 through a first connecting piece 91, and the first connecting piece 91 and the second connecting piece 92 can be in the form of bolts and are perpendicular to the first upper fixing block 71; the below of sensor 8 is provided with first fixed block 73 down, and first fixed block 73 level sets up and fixes on floating plate 2, and the one end that is close to fixed plate 1 center is connected with second fixed block 74 down through fourth connecting piece 94, and second fixed block 74 then fixed welding is on fixed plate 1 down, and the one end that fixed plate 1 center was kept away from to first fixed block 73 is connected with the lower extreme of sensor 8 through third connecting piece 93, and wherein third connecting piece 93 and fourth connecting piece 94 all can be the bolt form, and sets up perpendicularly with first fixed block 73 down.

With the above arrangement, after the fork 4 is inserted into the object, the floating plate 2 is subjected to a downward force, which is transmitted to the first lower fixing block 73 and the second upper fixing block 72 welded to the floating plate 2, so that the first lower fixing block 73 directly generates a downward pulling force on the lower end of the sensor 8 through the third connecting member 93; at the same time, the second upper fixing block 72 will generate a downward pulling force to the end of the first upper fixing block 71 near the center of the fixing plate 1, and since the fixing plate 1 is provided with buckling claws near the four corners thereof, the fixing plate 1 is fixed on the lifting platform, when the floating plate 2 applies force to the end of the first upper fixing block 71 near the center of the fixing plate 1 through the second upper fixing block 72, the fixing plate 1 will generate a deformation trend that the middle of the fixing plate is sunk and the two sides of the fixing plate are fixed, the trend will cause the end of the first upper fixing block 71 far from the center of the fixing plate 1 to generate an upward force, the force will directly act on the upper end of the sensor 8 through the first connecting piece 91, the upper end of the sensor 8 is finally caused to receive an upward pulling force, and the lower end of the sensor 8 is caused to receive a downward pulling force, so that the sensor 8 generates deformation displacement, and further, through the existing force measuring device, the object weight of the forklift truck is converted into the weight of the object to be plugged in the forklift, and the object is weighted.

In the above-mentioned force measuring process, in order to reduce the excessive tensile force applied to the lower end of the sensor 8 or avoid excessive deformation, the second lower fixing block 74 is disposed at the end of the first lower fixing block 73 near the center of the fixing plate 1, and the connection tensile force of the fourth connecting piece 94 can reduce the floating displacement of the floating plate 2 as much as possible, thereby achieving the purpose of reducing the variable at the lower end of the sensor 8, and finally the parameter relationship between the deformation amount and the force of the sensor 8 can be realized by the software setting in the prior art, and the problem that the force cannot be measured due to the deformation capacity of the lower end of the sensor 8 is not reduced.

Example two

A warehouse forklift scale, not shown in the drawings, but referring to fig. 3-5, is different from the first embodiment in that: the first upper fixing block 71 and the second lower fixing block 74 are fixedly welded to the floating plate 2, and the first lower fixing block 73 and the second upper fixing block 72 are fixedly welded to the fixed plate 1.

Thus, after the fork 4 is inserted into the object, the floating plate 2 will be subjected to a downward force, which will be transmitted through the floating plate 2 to the first upper and second lower fixed blocks 71 and 74 welded thereto in one piece, so that the first upper fixed block 71 directly generates a downward pressure on the upper end of the sensor 8 through the first connection 91; at the same time, the second lower fixing block 74 will generate a downward pressure to the end of the first lower fixing block 73 near the center of the fixing plate 1, and since the fixing plate 1 is provided with the buckling claws near the four corners thereof, the fixing plate 1 is fixed on the lifting platform, when the floating plate 2 applies a force to the end of the first lower fixing block 73 near the center of the fixing plate 1 through the second lower fixing block 74, the fixing plate 1 will generate a deformation trend that the middle is sunk and the two sides are fixed, the trend will cause the end of the first lower fixing block 73 far from the center of the fixing plate 1 to generate an upward force, the force will directly act on the lower end of the sensor 8 through the third connecting piece 93, the lower end of the sensor 8 is subjected to an upward pressure, finally the upper end of the sensor 8 is subjected to an upward pressure, the force will directly cause the sensor 8 to generate a deformation displacement, and the object weight of the object to be inserted into the forklift is converted into the object weight through the existing force measuring device, and the object weight is measured at the same time. Therefore, the difference between the second embodiment and the first embodiment is that the stress mode of the sensor 8 is changed, the two sides of the sensor 8 of the first embodiment are pulled, and the two sides of the sensor 8 of the second embodiment are pressed, and in particular, the mode can be selected according to the actual working condition.
