The rotary beam (5) and the lower transverse beam (7) are formed by hinging bolts through the rotary seat (6), ejection motion stopping mechanisms (10) capable of enabling the carrier rollers (2) to be braked are welded to the two ends of the rotary beam (5), and each ejection motion stopping mechanism (10) comprises a shifting fork (11) hinged to the vertical roller (1), a rotary shaft (12), a swing shaft (13), an outer supporting column (14), a pull pin (15) and a spring (16) arranged at the small end of the pull pin (15) in a sleeved mode. According to the automatic aligning carrier roller set, when a rubber belt deviates, the automatic aligning carrier roller set has enough driving torque to easily push and rotate a carrier roller set frame, the movement of the automatic aligning carrier roller set is sensitive, the automatic deviation correction function is fully achieved, the effect of preventing the operation of a conveying belt from deviating is obvious, and the ejection type braking mechanisms guarantee the product service life.
Description
Technical field
The present invention relates to belt conveyer constituent elements technical field, particularly a kind of self-centering idler group.
Background technology
Belt conveyer, in production run, often can cause convey materials to leak because load-transfer device departs from centre, has a strong impact on mass transport, and therefore in course of conveying, people can use aligning carrier roller group, to prevent belt deflection.The adhesive tape of travelling apron moves and has a characteristic on its carrying roller: adhesive tape is along vertical carrying roller axis direction operation forever, as long as therefore can control carrying roller vertical roller carrier shaft line under adhesive tape plane, rotates an angle, can control adhesive tape service direction.On travelling apron, the self-centering idler of various models utilizes adhesive tape on carrying roller, to move this characteristic exactly at present, the additional power of using sideslip adhesive tape to produce by mechanism, make an angle of carrying roller group frame rotation, reach the object of adhesive tape being carried out to tuningout, correction.But this point point additional power that only directly relies on rubber belt from deviating to produce pushes away motionless carrying roller group frame around its vertical axis revolving, because carrying roller group frame wants to do vertical revolution under adhesive tape, except overcoming in-house mechanical friction resistance, also need to overcome adhesive tape and upper material thereof to the caused friction drag of the positive pressure of carrying roller, the caused resistance of adhesive tape sag, equipment corrosion, dust, the resistance that the reasons such as blanking cause, for groove profile carrier roller, must overcome groove angle and change the resistance causing, the summation of these resistances is far longer than the additional propelling thrust that sideslip adhesive tape produces, therefore these aligning carrier rollers in actual use, when rubber belt from deviating, move dull or do not move at all, will cause material unrestrained, wearing and tearing belt conveyor, reduce the service life of belt conveyor and bring potential safety hazard.
Summary of the invention

The specific embodiment
Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail.
As shown in Figure 1, a kind of self-centering idler group, comprise two middle idler rollers (4), a side carrying roller (2), rotating beam (5), rotary seat (6), cross sill (7) and launch stop motion mechnism (10), carrying roller group is connected with the draw-in groove being welded on rotating beam (5) support, rotating beam (5) consists of with bolted splice rotary seat (6) with cross sill (7), and positioning plate (3), support wheel (8) is installed and supports wheel carrier (9).Described positioning plate (3) is for controlling the rotating beam anglec of rotation, and support wheel (8) and support wheel carrier (9) combination are used for keeping rotating beam spin balancing.The described stop motion mechnism (10) that launches is welded on rotating beam (5) two ends, and edger roll (1) is arranged on and launches stop motion mechnism (10) top.
As shown in Figure 2 and Figure 3, described in, launching stop motion mechnism is assembled by fork (11), rotating shaft (12), balance staff (13), outer pillar (14), pull pin (15), spring (16).Shift fork (11) is articulated and connected by screw and edger roll (1), side carrying roller (2) is connected with outer pillar (14) by the draw-in groove on outer pillar (14), shift fork (11) overlaps pillar (14) outside and above by rotating shaft (12), connects, balance staff (13) is through shift fork (11), outer pillar (14) and finger (15), and spring (16) is enclosed within the little head end of finger (15) and side carrying roller (2) is given prominence to block (17) over against position.
When edger roll (1) is subject to rubber belt from deviating thrust, promote shift fork (11) and take rotating shaft (12) as axle center to side carrying roller (2) direction rotation, shift fork (11) drives balance staff (13) to move to side carrying roller (2) direction, balance staff (13) gives finger (15) to side carrying roller direction thrust, when reaching certain thrust, spring (16) is compressed, finger (15) starts to move to side carrying roller (2) direction, when finger (15) moves to the outstanding block (17) of side carrying roller (2) and locates, the side carrying roller (2) of rotation is blocked by finger (15), side carrying roller (2) braking of stopping the rotation, thereby changed adhesive tape to the friction force balance between left and right sides carrying roller (2) on carrying roller group frame, to the side carrying roller (2) being braked, there is cliding friction subsidiary load in adhesive tape, this cliding friction subsidiary load traction carrying roller group frame rotates around its vertical rotary seat (6), multiple roll aligning carrier roller starts tuningout work, rotating beam (5) is revolution certain angle under rotary seat (6) claims, positioning plate (3) is controlled rotating beam (5) anglec of rotation, the combination of support wheel (8) and support wheel carrier (9) keeps rotating beam spin balancing, when the thrust decay of rubber belt from deviating opposite roller (1) is when disappearing, spring (16) stretches promotion finger (15) and moves to reversing sense, finger (15) drives balance staff (13) to move to reversing sense, balance staff (13) drives shift fork (11) to move to reversing sense, shift fork (11) be take rotating shaft (12) as axle center to opposite spin, and side carrying roller (2) stops braking and starts rotation, and rotating beam (5) is revolution certain angle under rotary seat (6) claims, edger roll resets, and completes automatic aligning process.When edger roll (1) is subject to rubber belt from deviating thrust again, according to the said process automatic aligning process that circulated.
The present invention has breakthrough in theory, it is by the displacement of sideslip adhesive tape, stir vertical carrying roller, start and launch stop motion mechnism brake side carrying roller, thereby changed adhesive tape to the friction force balance between left and right sides carrying roller on carrying roller group frame, active friction force between side carrying roller and adhesive tape is increased greatly, to the side carrying roller being braked, there is cliding friction subsidiary load in adhesive tape, the function that this cliding friction subsidiary load has traction carrying roller group frame to rotate around its vertical axle bed, can be used as the active moment that promotes carrying roller group frame, make carrying roller group frame rotate an angle, thereby reach the object of automatic deviation correction, and be no longer subject to the restriction of rubber belt from deviating amount.
