Description
Technical field
The utility model relates to a kind of belt load transfer device, specifically, relates to the self-centering idler that uses on a kind of band conveyor.
Background technology
Band conveyor is that industries such as mine transportation, electric power, chemical industry, metallurgy, harbour are used a kind of load transfer device comparatively widely, since discharging point not just, swabbing pig cleans the reasons such as gradient extension of clean and conveyer, and belt " deviation phenomenon " is the chronic disease of this conveyer of puzzlement always.Chinese patent CN2293543Y discloses the parallel aligning carrier roller of a kind of load-transfer device link-type, be mainly used in and prevent " deviation phenomenon ", its advantage is that linkage can be hidden in the base, but still there is following deficiency in it, because on the line of centers that is centered close to base of bearing seat, cause the arm of force of lever too short, thereby influenced its tuningout ability, the sensitivity of tuningout reduces.
Summary of the invention
The purpose of this utility model provides strong, the highly sensitive self-centering idler of a kind of tuningout ability.
The technical scheme that realizes above-mentioned purpose is: a kind of self-centering idler, comprise frame, left side roller rack, left side carrying roller, right roller rack, right carrying roller, middle idler roller, edger roll and lever, a left side, right roller rack below all has the bearing seat on the frame of being fixed on, all be supported with transmission shaft in the Y-axis bearing by bearing, and captive joint with left roller rack in the upper end of left side transmission shaft, captive joint with right roller rack in the upper end of the right transmission shaft, a left side, the lower end of right both sides transmission shaft is fixedly connected with left connecting rod and right connecting rod respectively, a left side, the other end of right connecting rod is hinged with the two ends of lever respectively, has eccentric throw h between the center o of bearing seat and the line of centers aa ' of frame.
After adopting technique scheme, owing to have eccentric throw h between the center o of bearing seat and the line of centers aa ' of frame, the line of centers aa ' that the length of left and right like this connecting rod just is located immediately at frame than the center o of bearing seat has increased the length of a width between centers h when going up, just increased the arm of force of lever, thereby improved the ability of carrying roller tuningout, also improved the clever lightness of carrying roller tuningout simultaneously.The utility model is simple in structure, and productive costs is low, by the automatic aligning of carrying roller, can alleviate the labour intensity of service personnel greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the K of Fig. 1 is to view;
Fig. 3 analyses and observe enlarged diagram for the A-A of Fig. 1.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As Fig. 1,2, shown in 3, a kind of self-centering idler, comprise frame 7, left side roller rack 6, left side carrying roller 5, right roller rack 1, right carrying roller 2, middle idler roller 4, edger roll 3 and lever 8, a left side, right roller rack 6,1 below all has the bearing seat 11 on frame of being fixed on 7, all be supported with transmission shaft 16 in the Y-axis bearing 11 by bearing 15, and captive joint with left roller rack 6 in the upper end of left side transmission shaft 16, captive joint with right roller rack 1 in the upper end of the right transmission shaft 16, a left side, the lower end of right both sides transmission shaft 16 is fixedly connected with left connecting rod 12 and right connecting rod 10 by nut 17 respectively, a left side, right connecting rod 12,10 the other end is hinged with the two ends of lever 8 by pin 9 respectively, has eccentric throw h between the center o of bearing seat 11 and the line of centers aa ' of frame 7.Deflection can design according to the width of frame 7 apart from h, and when frame 7 was wide, eccentric throw h amplified, otherwise when frame 7 was narrow, eccentric throw h dwindled.
As shown in Figure 3, the bottom of left and right roller rack 6,1 has and connects iron plate 13, the transmission shaft 13 of the right and left respectively with is connected iron plate 13 and welds.Adopt this structure, be convenient to being connected of transmission shaft 16 and left and right roller rack 6,1.
As shown in Figure 3, the upper end of bearing seat 11 is set with cover of dust 14.Adopt this structure can prevent that dust etc. from entering in the bearing seat 11, prevent that transmission shaft 16 is stuck by dust, guarantee the sensitivity of carrying roller automatic deflection adjusting.
Principle of work of the present utility model is as follows: when belt to the right when " sideslip ", the edger roll 3 on the right roller rack 1 is touched on the right leather belt limit, the middle idler roller 4 that edger roll 3 drives on right carrying roller 2 and the right roller rack 1 is done equal angular rotation in the same way, and drive and right roller rack 1 are done equal angularly to rotate in the same way, right roller rack 1 drives the transmission shaft 16 of captiveing joint with it again and does equal angular rotation in the same way, this transmission shaft 16 drives the right connecting rod 10 of captiveing joint with it and does equidirectional rotation, under the effect of lever 8, left side connecting rod 12 is and then right connecting rod 10 dos rotation in the same way also, the transmission shaft 16 that left side connecting rod 12 drives the left side rotates, and drive left roller rack 6 by this transmission shaft 16 and do equidirectional rotation, left carrying roller 5 is followed the tracks of the left leather belt limit simultaneously.After regulating end, edger roll 3 is left on the right leather belt limit, and the left leather belt limit promotes left carrying roller 5, drives the unit return in the time of during belt returns, and right carrying roller 2 is followed the tracks of the right leather belt limit simultaneously, and is ready for regulating next time.When belt left " sideslip " motion similar to the above process but that direction is opposite will take place.
