Description

Technical Field

[0001] The utility model relates to a mobile weighing device. Background Art

[0002] In the prior art, when the weighing tray moves up and down, the force of ropes, chains, drag chains, etc. acting on the tray changes, which affects the accuracy of weighing. Utility Model Content

[0003] The utility model aims to provide a mobile weighing device with higher weighing accuracy.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A mobile weighing device, characterized in that it includes a weighing gantry, a scale and a hanging weight, the hanging weight is connected to the top plate of the weighing gantry, the top of the hanging weight is connected to a rope or chain, the scale is located in the frame cavity of the weighing gantry, the upper end of the scale is connected to the top plate of the weighing gantry, the lower end of the scale is hung on the upper end of the pallet support ear, and buffer protrusions are convexly provided on the two inner side walls of the weighing gantry above the pallet support ear. During the rising and falling process, a gap is left between the pallet support ear and the buffer protrusion, and a rope, chain or drag chain is mounted below the weighing gantry.

[0006] The weighing gantry is in a square frame shape, a C shape or an S shape.

[0007] The upper end of the scale is connected to the top plate of the weighing gantry through bolts A, and the top plate of the pallet support ear is suspended to the lower end of the scale through bolts B.

[0008] The gap is 5 mm.

[0009] The two ends of the hanging weight are connected to the top plate of the weighing gantry through bolts C, and the ends of the rope or chain are connected to the hanging weight.

[0010] A spherical washer and a conical washer are provided between the bolt A and the top plate of the weighing gantry.

[0011] The beneficial effects of the utility model are as follows: the pallet support ears are connected below the scale in the weighing gantry, and the pallet has heavy objects to be weighed. The hanging weight above the weighing gantry moves up and down with the weight of the pallet. Heavy objects such as ropes, chains or drag chains are hung below the weighing gantry, and no matter how the load below changes, the pallet weighing result will not be affected. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] In order to more clearly illustrate the embodiment of the utility model, the embodiment will be described below in conjunction with the accompanying drawings.

[0013] Figure 1 It is a structural schematic diagram of the utility model in use state.

[0014] Figure 2 yes Figure 1 A simplified diagram of the planar structure diagram. DETAILED DESCRIPTION

[0015] The following examples are merely used to illustrate possible implementations of the present invention, but are not intended to limit the scope of protection of the present invention, so it is necessary to make it clear in advance.

[0016] like Figure 1 and Figure 2 As shown, a mobile weighing device of the utility model includes a weighing gantry 1, a scale 2 and a hanging weight 3. The weighing gantry is in the shape of a square frame. The hanging weight 3 is connected to the top plate of the weighing gantry 1. The top of the hanging weight 3 is connected to a rope or chain 4. The scale 2 is located in the frame cavity of the weighing gantry 1. The upper end of the scale 2 is connected to the top plate of the weighing gantry 1. The lower end of the scale 2 is connected to the upper end of the pallet support ear 10. Buffering protrusions 11 are convexly provided on the two inner side walls of the weighing gantry above the pallet support ear. During the rising and falling process, a gap is left between the pallet support ear 10 and the buffering protrusion 11. The gap is preferably 5 mm. A rope, chain or drag chain 5 is mounted below the weighing gantry 1.

[0017] The weighing gantry can also be C or S-shaped. The upper end of the scale 2 is connected to the top plate of the weighing gantry by bolt A20, and a spherical washer and a conical washer are provided between the bolt A and the top plate of the weighing gantry. The top plate of the pallet lug 10 is suspended below the scale 2 by bolt B30. The two ends of the hanging weight 3 are connected to the top plate of the weighing gantry 1 by two bolts C40, and the end of the rope or chain 4 is connected to the hanging weight.

[0018] In the weighing gantry of the utility model, the pallet support ears are connected to the bottom of the scale, and the pallet has the heavy objects to be weighed. The adjustable hanging weight above the weighing gantry carries the weight of the pallet and moves up and down. A rope chain or a drag chain or other heavy objects are hung under the weighing gantry, and no matter how the load below changes, it will not affect the pallet weighing result.
