Detailed Description
To facilitate understanding of those skilled in the art, the structure of the present invention will now be described in further detail by way of examples in conjunction with the accompanying drawings: it should be understood that the steps mentioned in the embodiment, except for the sequence specifically mentioned, can be performed simultaneously or partially simultaneously according to the actual requirement.
Referring to fig. 4-10, a method for modifying a roller mechanism for a tubular belt conveyor, the original roller mechanism comprises six rollers which are arranged in a hexagonal distribution, the rollers are respectively formed by connecting two ends of a roller with mounting shafts in a rotating manner, and the original roller is shown in fig. 1. Based on the applicant's discovery that the direction of deformation of the tube belt is different for different weight of the load transportation, the following optimization method is proposed.
The carrier roller transformation method comprises the following specific steps:
s1, installing a first roller to be sleeved in the middle of the outer surface of a roller at the bottommost roller to increase the supporting diameter of the bottom roller, and defining the supporting diameter increment of the bottom roller as L 1 The average conveying amount of the conveying belt of the tubular belt conveyor is Q, the conveying amount increment is delta Q, the filling rate of the tubular belt conveyor is k, the circumferential rate is pi, the conveying speed of the tubular belt conveyor is v, the density of the carried object is rho, and the diameter of the current tubular belt is d 1 Calculating the support diameter increment of the bottom carrier roller according to the formula 1 to obtain L 1 ：
S2, mounting a second roller to be sleeved in the middle of the outer surface of the roller on the two sides of the bottom to increase the supporting diameter of the roller on the two sides of the bottom, and defining the increased supporting diameter of the roller on the two sides of the bottom as L 2 The diameter of the current band is d 2 Calculating and obtaining the support diameter increment L of the carrier rollers at the two sides of the bottom according to a formula 2 2 ：
Specifically, the specific positions of the bottom idler and the bottom two-side idlers in this embodiment are shown in fig. 5. In the prior art, the diameters of the bottom idler and the idlers on two sides of the bottom are the same, so that the problems are solved. Equations 1 and 2 in this example are derived as follows:
first, defining Q as the mass of material per meter length (unit kg/m) and v as the running speed of the conveyor belt (unit m/s), the conveying capacity Q of the tubular belt conveyor is known:
q =3.6qv (unit: t/h) (equation 3);
then, the cross-sectional area of the material accumulated in the tube band is defined as F (unit: m) 2 ) The bulk density is ρ (unit: t/m 3 ) Then, in case of filling the inside of the pipe band, due to the finally calculated L 1 In millimeters, where the conversion factor between millimeters and meters is added, the mass q of the material per meter length:
q =1000F ρ (formula 4);
when the pipe is known to be filled in the band, the cross-sectional area F 0 ＝πd 2 However, since the filling rate of the tube strip is generally k =50% to 75%, the above inputs are substituted into equation 4, so that the mass q of the material per meter length is:
q＝250πkd 2 ρ (formula 5);
because the bottom end carrier roller is positioned at the bottommost end of the regular hexagon, the stress of the carrier roller at the bottommost end is half of the mass q of the material per meter length according to the stress analysis of the regular hexagon, and therefore the stress q of the first roller sleeve is determined according to the stress condition q of the first roller sleeve 1 Half the mass q of the material per meter length, we get:
q 1 ＝q/2＝125πkd 2 ρ (formula 6);
substituting equation 6 into equation 3, the diameter d of the tubular band can be calculated 1 Comprises the following steps:
when the conveying amount of the pipe belt machine is increased, defining the conveying amount increase amount delta Q, substituting the total conveying amount = Q + delta Q into a formula 7 to obtain the diameter of the current pipe belt as
Finally, the support diameter of the bottom idler increases by an amount L 1 (in mm) satisfies the following relationship:
installing a second roller to be sleeved in the middle of the outer surface of the roller of the carrier rollers at the two sides of the bottom to increase the supporting diameters of the carrier rollers at the two sides of the bottom, and defining the increase of the supporting diameters of the carrier rollers at the two sides of the bottom as L 2 The diameter of the current band is d 2 ，L 2 The estimation process of (c) is as follows.
Firstly, according to the formulas 3, 4 and 5, the mass q of the material per meter length is as follows:
q＝250πkd 2 ρ (formula 5);
because the supporting rollers at the two sides of the bottom end are positioned at the two sides of the bottommost end of the regular hexagon, the stress of the supporting roller at the bottommost end is half of the mass q of the material per meter length according to the stress analysis of the regular hexagon, and therefore the stress q of the first roller sleeve is half of the stress q of the first roller sleeve 2 Half the mass q of the material per meter length, we get:
q 2 ＝q/2＝125πkd 2 ρ (formula 8);
when the conveying amount of the pipe belt machine is increased, defining the conveying amount increase amount delta Q, substituting the total conveying amount = Q + delta Q into a formula 8 to obtain the diameter of the current pipe belt as
Finally, the supporting diameter of the supporting rollers at the two sides of the bottom is increased by L 2 (in mm) satisfies the following relationship:
in summary, when the idler is mounted in the form of a regular hexagon, the first roller sleeve and the second roller sleeve have the same diameter adjustment.
The invention can effectively and directly carry out reducing transformation on the bottommost carrier roller and the carrier rollers at two sides of the bottom under the condition of not disassembling the carrier roller mechanism, thereby effectively adapting to the problem of pipe belt deformation generated in the actual operation of equipment, and improving the supporting effect and the supporting stability of the carrier roller mechanism on the pipe belt on the premise of convenient transformation and low cost, thereby effectively preventing the carrier roller mechanism from being deformed and damaged due to uneven stress.
And can be according to the influence pipe area various factors of warping, like the influence to the pipe area deformation rate such as the average delivery capacity of the equipment of equipment, the delivery capacity increases, the packing rate of pipe tape machine, the conveying speed of pipe tape machine, the density of the year thing, and the diameter of current pipe area, effectively carry out accurate control to bottommost bearing roller, and the reducing volume of bottom both sides bearing roller, thereby further promote the supporting effect and the support stability of bearing roller mechanism after the reducing to the pipe area, with effectively further prevent that bearing roller mechanism from leading to producing because of the atress is uneven and warping, damaging.
