The specific embodiment
Embodiment one
The idler assembly structural front view that Fig. 2 provides for the utility model embodiment one, the idler assembly structure birds-eye view that Fig. 3 provides for the utility model embodiment one.The utility model embodiment one provides a kind of idler assembly 1, comprises the carrier roller frame of bending, and this carrier roller frame has the tilting section 12 of middle part flat segments 11 and both sides, and the two ends of tilting section 12 are used for being fixedly linked with the longeron 21 of belt feeder; Above-mentioned idler assembly 1 also includes the middle carrying roller 13 that lies on the flat segments 11 and two side carrying rollers 14 that favour these centre carrying roller 13 settings; Wherein, Two side carrying rollers 14 are the splayed setting, and two side carrying rollers 14 medial extremity and midway location of flat segments 11 separately articulate through horizontal shaft, and two side carrying rollers 14 can be articulated in same point; Also can be articulated in 2 points respectively; Present embodiment be with 2 be example, at the midway location of flat segments 11 two adjacent pivoting points are set, so that an end of side carrying roller 14 is fixed; The other end of two side carrying rollers 14 is used for connecting with respect to two longeron 21 parallel motions of belt feeder respectively.
When belt feeder moves, if belt deviation through moving side carrying roller 14, changes the side carrying roller 14 and the connection location of longeron 21, thereby belt is rectified a deviation.Its principle is following: describe for convenient; Hereinafter claims that two side carrying rollers 14 are carrying roller one and carrying roller two; During the belt operation, pass through power F1 who points to carrying roller two of friction generates between carrying roller one and the belt, and power F2 who points to carrying roller one of the friction generates between carrying roller two and the belt; The size of F1 and F2 is directly proportional with contact surface size between carrying roller and the belt, that is: the area of contact between carrying roller and the belt is big more, and the friction thrust that is produced is big more, and the area of contact between carrying roller and the belt is more little, and the friction thrust of generation is more little.If belt is to a side sideslip of carrying roller one; Through moving the connection location that carrying roller one changes carrying roller one and belt longeron 21; Also promptly changed the angle of carrying roller one, thereby increased the area of contact between carrying roller one and the belt, can increase the friction force between carrying roller one and the belt with belt direction of travel; Belt to the thruster away from carrying roller one, just can be realized the purpose of belt deviation rectifying.
To defective of the prior art; Because the working strength of adjustment belt is bigger; The utility model embodiment one changes the area of contact between side carrying roller 14 and the belt through moving an end of side carrying roller 14, after belt operation placed in the middle; Side carrying roller 14 is fixed on the correct position on the curb girder, thereby has reduced working strength of workers.
Being connected between the longeron 21 of side carrying roller 14 and belt feeder can have multiple mode; A kind of embodiment is; External side end at side carrying roller 14 is connected with hook; Through hook side carrying roller 14 is connected on the longeron 21, the length of hook can be chosen wantonly, can realize changing and the belt area of contact as long as satisfy the moving range of side carrying roller 14.
Another kind of embodiment is, side carrying roller 14 is set on the expansion link, and the external side end of side carrying roller 14 is set on the expansion link, adjusts the installation site of side carrying roller 14 on longeron 21 through stretching of expansion link.
The idler assembly that the utility model embodiment one provides is through being provided with the side carrying roller; One end and the carrier roller frame of side carrying roller are articulated; The position that the adjustment other end and belt feeder longeron link to each other changes the area that contacts between side carrying roller and belt, realizes the purpose of belt deviation rectifying, compared with prior art; Reduce labour intensity, improved correction efficient.
Embodiment two
The belt feeder structural front view that Fig. 4 provides for the utility model embodiment two, the belt feeder structure birds-eye view that Fig. 5 provides for the utility model embodiment two.The utility model embodiment two provides a kind of belt feeder 2; Comprise belt (not shown) and the longeron 21 that laterally arranges, also comprise the idler assembly that the utility model any embodiment provides, wherein; When belt is in running order; Carrying roller 13 and side carrying roller 14 operate in the top of idler assembly in the middle of being adjacent to, and captive joint with longeron 21 respectively in the two ends of carrier roller frame tilting section 12, and side carrying roller 14 connects with respect to two longeron 21 parallel motions.
Particularly, side carrying roller 14 connects with the hook that can adopt described in the embodiment one being connected of longeron 21 or expansion link connects, and realizes the removable of side carrying roller 14.
During belt feeder 2 operations; Owing to reasons such as belt is aging cause belt deviation easily; Correction to belt realizes through the connection location that changes between side carrying roller 14 and the longeron 21; Through changing the connection location between side carrying roller 14 and the longeron 21, just changed the area of contact between side carrying roller 14 and the belt, thereby realized the purpose of belt deviation rectifying.
The adjustment of offside carrying roller 14 for ease is provided with the external side end of side carrying roller 14, and promptly the end near longeron 21 is higher than longeron 21, thereby when making the belt operation, side carrying roller 14 can not blocked by belt fully, is convenient to adjustment.If belt is to be connected through the mode of linking up with 21 of longerons; When belt during to a side sideslip, move to belt direction of travel through hook sideslip one side, or the hook of mobile opposite side; The opposite sense of hook to the belt operation moved, move between two parties up to belt.
In practical application, it is acute angle that the axis of side carrying roller 14 and the angle of belt direction of travel are set, and in side carrying roller variable range, this acute angle is more little, and friction force is big more.Preferably, above-mentioned angle is 30 degree, and when practical application, rectifying effect is best.
The above-mentioned idler assembly of many groups can be set on belt feeder 2, when the setting range of a side carrying roller 14 reaches capacity, the side carrying roller 14 on removable other group idler assemblies, fit adjustment correction.
The belt feeder that the utility model embodiment two provides is through being provided with the side carrying roller on idler assembly; The side carrying roller movably is connected with longeron; Connection location through changing side carrying roller and longeron changes the friction force between side carrying roller and the belt, thereby reaches the purpose of correction.Compare with directly adjusting belt in the prior art, reduced labour intensity, improved work efficiency.
What should explain at last is: above embodiment is only in order to the technical scheme of explanation the utility model, but not to its restriction; Although the utility model has been carried out detailed explanation with reference to previous embodiment; Those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these are revised or replacement, do not make the scope of each embodiment technical scheme of essence disengaging the utility model of relevant art scheme.
