Abstract
The utility model belongs to belt-type conveying equipment fittings equipment technical field, discloses a kind of sliding powerful self-centering idler.Form the technical scheme of this self-centering idler: its structure comprises three sections of rollers and forms trough idler, roller rack, left and right block roller and conveyer frame, load-transfer device frame is provided with the four-bar linkage of double rocking lever composition, and the front end of this four-bar linkage is connected with roller rack axle respectively, left and right block roller is then arranged at its rear end.Not only rectifying effect is good for this sliding powerful self-centering idler, but also the damage to load-transfer device when can alleviate correction, extend the service life of conveying machinery.
Description
Technical field
The utility model belongs to belt-type conveying equipment fittings equipment technical field, particularly relates to a kind of sliding powerful self-centering idler.
Background technology
Common aligning carrier roller as shown in Figure 1 primarily of three sections of rollers 1,2 and 3 form trough idler, roller rack 4, be arranged at these support both sides left and right block roller (edger roll) 5,6 and formed by rotating shaft 7 and conveyer frame 8, when conveyer normally runs, the longitudinal centerline of load-transfer device overlaps with the line of centers of conveyer frame, with the axes normal of aligning carrier roller, when belt deflection, due to its effect of inertia, the lateral edges of belt deflection contacts with the sideslip side blocking roller (edger roll) of aligning carrier roller mechanism, under the effect of friction force, impel it to drive aligning carrier roller 7 to rotate generation angular transposition around the shaft, even if the axis of idler machining is 90 ° of+α (namely adding a α angle again) by original and load-transfer device longitudinal centerline vertical rotation, the component making it return is produced in the linear running of load-transfer device and the rotary course of carrying roller, the load-transfer device of such sideslip progressively gets back to frame central position, reach conveyer normally to run, complete process of once rectifying a deviation.The aligning carrier roller of this structure is due in its both sides and it is with straight line being provided with fixed type block roller, and this block roller is merely able to the bias correcting being realized load-transfer device by friction, there is the problem of the little and weak effect of correction power, and because only frictionally realizes, greatly can accelerate the process of the frictional failure of load-transfer device, shorten its service life.
Utility model content
The purpose of this utility model be just to provide a kind of good to load-transfer device rectifying effect, damage little sliding powerful self-centering idler.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of sliding powerful self-centering idler, its structure comprises three sections of rollers and forms trough idler, roller rack, left and right block roller and conveyer frame, it is characterized in that: the four-bar linkage being provided with double rocking lever composition in described load-transfer device frame, the front end of this four-bar linkage is connected with described roller rack axle respectively, described left and right block roller is then arranged at its rear end.
The additional technical feature forming above-mentioned sliding powerful self-centering idler comprises:
---described block roller is made up of two or more the block roller group be arranged on same fixed mount, and described fixed mount axle is fixed on the rearward end of described double rocker mechanism;
---the leading portion portion forming the double rocking lever of described four-bar linkage is shorter than its back segment portion.
Sliding powerful self-centering idler provided by the utility model compared with prior art, have the following advantages: one, this aligning carrier roller adopts the four-bar linkage of double rocking lever composition, aligning carrier roller group entirety is enable to do level curve slipping motion, namely while aligning carrier roller group produces angular variable, also produce longitudinal direction and cross travel, have the advantages that correction slippage amplitude is large, centering capacity is strong; Its two, because the left and right block roller of sliding aligning carrier roller group is made up of multiple block roller group be arranged on same fixed mount, there is adjustable function, the control position of block roller and load-transfer device therefore can be made to reach optimum regime; Its three, owing to adopting two block roller one axle center that the area of contact of two block roller and load-transfer device can be made to strengthen, and greatly strengthen friction force, the centering capacity of aligning carrier roller obtains larger performance.

Detailed description of the invention
Be described in further details below in conjunction with the structure of accompanying drawing to the sliding powerful self-centering idler that the utility model provides.
The structural representation of the sliding powerful self-centering idler provided for the utility model as shown in Figure 2,3.The structure forming this sliding powerful self-centering idler comprises three sections of rollers 1, the trough idler of 2 and 3 formation load-transfer devices, roller rack 4 and conveyer frame 8, load-transfer device frame is provided with by a left side, right double rocking lever 10, the four-bar linkage of 11 compositions, this left side, front end and roller rack 4 axle of right double rocking lever connect and compose slippage activity hinge 12, 13, fixing hinge 14 is connected and composed with conveyer frame 8 axle in the middle part of it, 15, left, right block roller 5 and 6 are arranged at a left side, the rear end of right double rocking lever, and with fixing hinge 14, 15 by a left side, right double rocking lever 10, the 11 connecting rod L1 being divided into leading portion portion to form respectively, the swing arm M1 that L2 and back segment portion are formed, M2, and according to lever principle, its leading portion portion connecting rod L1, L2 is shorter than its back segment portion swing arm M1, the length of M2.
Its principle is, when conveyer load-transfer device left sideslip time (offset left) at this moment the left part edge of load-transfer device and the block roller 5 in left side come in contact and produce larger friction force, and make connecting rod L
1connecting rod L is simultaneously rotated to lower right side
2rotate to upper right side, the idler machining two ends then driven by left and right double rocking lever are to different directions slippage, except the correction power producing common aligning carrier roller, also make overall flute profile idler machining driving conveying belt and throughout its mass move right like this, the correction power of this correction power common aligning carrier roller in Dayu far away simultaneously.
In the structure forming above-mentioned sliding powerful self-centering idler, as shown in Figure 4, block roller 5 and 6 is arranged at by two (or more) the block roller group formation that block roller 17 and 18 on same fixed mount 16 forms respectively, and fixed mount is fixed on the rearward end of double rocking lever 10,11 by rotating shaft 19 axle, it can make the control position of block roller and conveying belt reach optimum regime; And this pair of block roller one axle center can make two block roller and the increasing of load-transfer device area of contact enhance friction force, makes the centering capacity of sliding aligning carrier roller obtain larger performance.
