Embodiment 1
[0038] The invention provides a belt conveyor counterweight box, such as figure 1 As shown, the counterweight box 100 includes: an outer box body 10, an inner box body 20 and a pressure detection device 30; the inner box body 20 is used to accommodate the counterweight block 110, the inner box body 20 is arranged in the outer box body 10, and Can move vertically relative to the outer box body 10 ; the pressure detection device 30 is installed on the outer box body 10 and connected with the inner box body 20 for carrying the inner box body 20 .
[0039] When using the counterweight box 100, the outer box body 10 is suspended and connected to the roller 200 in the belt conveyor; the counterweight block 110 is placed in the inner box body 20, and the gravity of the counterweight block 110 drives the inner box body 20 in the outer box body 10, the gravity of the inner box body 20 and the counterweight 110 acts on the pressure detection device 30, and the pressure detection device ...
Embodiment 2
[0052] The invention provides a belt conveyor counterweight system, such as Figure 4 and Figure 5 As shown, the counterweight system includes: a counterweight 110 and the above-mentioned belt conveyor counterweight box 100, the counterweight box 100 is connected with the roller 200 in the belt conveyor, and can pull the roller 200 to translate.
[0053] When the counterweight box 100 includes the first pressure detection device 31 and the second pressure detection device 32, the first pressure detection device 31 and the second pressure detection device 32 are distributed along the axial direction of the drum 200, and the two ends of the outer box body 10 are respectively connected to each other. Correspondingly connected to the two ends of the rotating shaft 210 of the drum. When the distribution of the counterweights 110 in the counterweight box 100 is biased towards one end, it will cause unbalanced force on both ends of the drum 200 . The first pressure detection devic...
Embodiment 3
[0057] The present invention provides a counterweight method for a belt conveyor, using the above-mentioned belt conveyor counterweight box 100, such as Figure 6 As shown, the counterweight method includes:
[0058] Step S10, loading the counterweight 110 into the inner box 20;
[0059] Step S20, comparing the sum of the values detected by each pressure detection device 30 with the design value of the counterweight, and when the sum is greater than or equal to the design value of the counterweight, stop loading;
[0060] Step S30 , comparing the difference between the values detected by each pressure detection device 30 with the deviation critical value, so that each difference is less than or equal to the deviation critical value.
[0061] This counterweight method can avoid excessive loading and ensure the accuracy of the total loaded weight; moreover, it can effectively control the distribution of the counterweight to make the counterweight distribution more uniform, ...
