Description

Technical Field

[0001] The utility model relates to the technical field of weighing, in particular to an anti-sway device applied to an electronic buffer platform scale. Background Art

[0002] PG (PGV) series electronic buffer platform scales use a double scale structure and spiral compression springs to absorb the impact energy during loading, and are equipped with high-precision single shear beam or GD rocker column sensors and intelligent weighing displays to ensure stable and accurate measurements under various weighing conditions. Therefore, PG (PGV) series electronic buffer platform scales are widely used in situations where lifting equipment is used to carry and weigh goods.

[0003] In the actual steel coil weighing work, due to the heavy weight of the steel coil and the high hoisting height, the steel coil has a great impact on the platform scale, causing the platform scale to sway left and right, seriously affecting the accuracy of weighing. Therefore, an anti-sway device applied to the electronic buffer platform scale is urgently needed to solve the problem of platform scale swaying when weighing steel coils and improve the accuracy of weighing. Utility Model Content

[0006] Preferably, each position limiting guide mechanism includes an upper ear plate fixed to the upper scale body and a lower ear plate fixed to the lower scale body, a guide rod is vertically fixed on the upper ear plate, and the guide rod extends downward and passes through the lower ear plate.

[0007] Preferably, a first guide hole for the guide rod to pass through is provided on the lower ear plate, and a second guide hole for the guide rod to pass through is provided on the fixed frame, and the first guide hole and the second guide hole correspond one to another in upper and lower directions.

[0008] When the steel coil is weighed, the impact of the steel coil causes the scale body to move up and down. At this time, the guide rods of each limit guide mechanism can move up and down along the first guide hole and the second guide hole, playing a guiding and limiting role in the up and down movement of the scale body, further preventing the scale body from shaking left and right.

[0009] Preferably, the upper end of the guide rod is fixed to the upper ear plate via a fixing piece.

[0010] Preferably, a threaded section is provided at the upper end of the guide rod, and the fixing member includes an upper fixing nut and a lower fixing nut threadedly connected to the upper end of the guide rod, and the upper fixing nut and the lower fixing nut are respectively located above and below the upper ear plate. The guide rod is fixed to the upper ear plate by the cooperation of the upper fixing nut and the lower fixing nut, and the upper fixing nut and the lower fixing nut are released to facilitate replacement of the guide rod.

[0011] The beneficial effects of the utility model are:

[0012] 1. The utility model has a simple structure. The four limit columns respectively limit the four corners of the scale body, which can effectively limit the left and right shaking of the scale body; the four limit guide mechanisms play a guiding and limiting role in the up and down movement of the scale body, further preventing the scale body from shaking left and right. The cooperation of the limit column and the limit guide mechanism reduces the shaking amplitude of the scale body during the measurement process, thereby improving the stability and accuracy of the weighing.

[0019] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0020] like Figure 4 As shown, the PG (PGV) series electronic buffer platform scale includes a base 1, an upper scale body 2 and a lower scale body 3 located above the base 1, a spiral compression spring 4 is arranged between the upper scale body 2 and the lower scale body 3, and a sensor 5 for weighing is installed between the lower scale body 3 and the base 1. The specific structure and weighing principle of the PG (PGV) series electronic buffer platform scale are all existing technologies and will not be repeated here.

[0021] like Figure 1 , 2 As shown, the utility model includes a fixed frame 6 fixed on the platform scale base 1, and four limit columns 7 with L-shaped cross-sections are vertically fixed on the fixed frame 6. The four limit columns 7 are respectively and one by one located at the outside of the four corners of the scale body. The upper scale body 2 and the lower scale body 3 are limited by the four limit columns 7, thereby effectively limiting the left and right shaking of the scale body.

[0022] A limit guide mechanism is installed on each side of the scale body. Each limit guide mechanism includes an upper ear plate 8 fixed to the upper scale body 2 and a lower ear plate 9 fixed to the lower scale body 3. A guide rod 10 is vertically fixed on the upper ear plate 8. The guide rod 10 extends downward and passes through the lower ear plate 9. A first guide hole for the guide rod 10 to pass through is provided on the lower ear plate 9. Figure 3 As shown, a second guide hole 11 for the guide rod 10 to pass through is provided on the fixing frame 6, and the first guide hole and the second guide hole 11 correspond one to another in upper and lower directions.

[0023] When the steel coil 14 is weighed, the scale body moves up and down due to the impact of the steel coil 14. At this time, the guide rods 10 of each limit guide mechanism can move up and down along the first guide hole and the second guide hole 11, which plays a role in guiding and limiting the up and down movement of the scale body, and further prevents the scale body from shaking left and right. The upper end of the guide rod 10 is fixed to the upper ear plate 8 through a fixing member, and a threaded section is arranged on the upper end of the guide rod 10. The fixing member includes an upper fixing nut 12 and a lower fixing nut 13 threadedly connected to the upper end of the guide rod 10. The upper fixing nut 12 and the lower fixing nut 13 are respectively located above and below the upper ear plate 8. The guide rod 10 is fixed to the upper ear plate 8 by the cooperation of the upper fixing nut 12 and the lower fixing nut 13. The upper fixing nut 12 and the lower fixing nut 13 are released, and the guide rod 10 can be easily replaced.

[0024] The utility model has a simple structure. The four limit columns 7 are used to limit the four corners of the scale body respectively, which can effectively limit the left and right shaking of the scale body; the four limit guide mechanisms play a guiding and limiting role in the up and down movement of the scale body, further preventing the scale body from shaking left and right. The cooperation between the limit column 7 and the limit guide mechanism reduces the shaking amplitude of the scale body during the measurement process, thereby improving the stability and accuracy of the weighing.
