Abstract
The utility model relates to a belt conveyor's tuningout device, by lower carriage (6), the mechanism (4) of giving a poor attention to can be followed the mechanism pivoted upper bracket (5) of giving a poor attention to, fix straight roller (3) on upper bracket (5), taper roller (1) on upper bracket (5), in below riding wheel axle (8) of upper bracket (5), riding wheel (10), slide (9) are constituteed, mainly used is automatic to rectifying to the conveyer belt when the conveyer belt off tracking, guarantees the smooth operation of conveyer belt, protection parts and conveyer belt. The utility model discloses rational in infrastructure, the effect of rectifying is obvious reliable, is a more practical tuningout bearing roller structure.
Description
The utility model is tuningout (correction) device of belt conveyor.
The general fed distance of band conveyor is longer, be in operation and often produce eccentric or snakelike operation, cause physical damage when serious, transport the material spill and leakage, the adhesive tape scratch is torn and is caused damage, traditional band conveyor adopts the both sides on rotating upper bracket that two straight rollers are installed the belt of band conveyor is rectified a deviation, because the linear velocity of each point is identical with the running velocity of belt conveyor on the straight roller in both sides, when off-centre takes place in belt, can not produce a correction power that significantly promotes the belt return, in use, rectifying effect is not obvious, easy damaged belt or parts.
Goal of the invention of the present utility model will provide a kind of exactly and can produce an obvious correction power when belt is eccentric make belt be returned to entopic idler structure in the conveyer operational process.
Summary of the invention of the present utility model is such, by lower bracket (6), be fixed on the widely different rotation mechanism (4) on the lower bracket (6), can be along the upper bracket (5) of widely different rotation mechanism dead axle rotation, be fixed on upper bracket (5) and go up the widely different rotatable two-way automatic aligning upper supporting roller that the straight roller (3) at middle part is formed, the top, inclined-plane of going up the both sides upper bracket of straight roller (3) at upper bracket (5) respectively is equipped with an awl roller (1) that is used for the belt of band conveyor is carried out tuningout, below, inclined-plane at upper bracket (5) respectively is equipped with a supporting-roller shaft (8) that is used to support upper bracket, can and guarantee that supporting-roller shaft effectively supports the support roller (10) of upper bracket can guarantee upper bracket (5) at tuningout the time along the widely different commentaries on classics of widely different rotation mechanism (4) dead axle having below each supporting-roller shaft, in the below of support roller (10) for the slide plate (9) that can limit the widely different commentaries on classics amplitude of upper bracket by lower bracket (6), be fixed on the widely different rotation mechanism (4) on the lower bracket (6), the widely different rotatable two-way automatic aligning snub pulley that can form along the upper bracket (5) that widely different rotation mechanism dead axle rotates respectively is equipped with an awl roller (1) that is used for the belt of belt conveyor is carried out tuningout in the top, inclined-plane of upper bracket (5) both sides.The gradient (11) of described upper bracket (5) and the angle between water surface direction are 7---30 °.The maximum widely different gyration OA ' of described restriction slide plate (9) restriction upper bracket and the angle between the OA are 20 °.A support roller (10) is installed under each supporting-roller shaft (8).The slide plate (9) that described slide plate (9) makes progress for the two ends bending.
Invention effect of the present utility model is such, owing to the awl roller is installed in the both sides of upper bracket, awl roller surface is unequal along the linear velocity of axis direction each point, the awl roller is as the Passive part of support tape operation, certain a bit (or a certain tangent plane) linear velocity on awl roller surface must equate with the adhesive tape running velocity, establishes the Ks of this o'clock on two awl rollers
1, K
2Point, then K
1, K
2The adhesive tape at some place equals zero with the slide relative amount of roller surface, increases gradually along the slide relative amounts of the little extreme direction of two awl rollers, and the distribution of its friction force is shown in Fig. 5 shade, and when adhesive tape is in B point normal position, the friction force equal and opposite in direction of roller, F are bored in both sides
1=F
2This two power equates with the formed level of torque of widely different commentaries on classics center O, direction is opposite, then two awl rollers are in the dynamic equilibrium state on the OA line, when adhesive tape was offset to B ' position, the state of equilibrium of both sides awl roller friction force was destroyed, as Fig. 6, this moment, right side awl roller friction force was bored the roller friction force greater than the left side, and F ' promptly makes a concerted effort
2＞F '
1, the formed widely different torque of two power differences is impelled corresponding angle of the widely different commentaries on classics of upper bracket, and both sides awl roller is on the OA ' line, and meanwhile the resultant direction of both sides awl roller friction force changes, F '
2And F '
1Be decomposed into mutually perpendicular two component, then adhesive tape turns back to the normal position that B is ordered under the effect of component GN and EM.Reach the purpose of automatic aligning.
