Abstract
The utility model discloses a guide roller. The guide roller is used for preventing a conveyer belt from deflecting and comprises roller bodies. The roller bodies are matched in a set mode. The roller bodies of each set comprise a first roller and a second roller, spiral strips are arranged on the surface of each first roller and the surface of each second roller, and the rotating directions of the spiral strips on the surface of each first roller and on the surface of each second roller are opposite. After optimization, the roller diameter r of each first roller and the roller diameter r of each second roller are the same, and the distance d between the axis of each first roller and the axis of each second roller satisfies the equation of 30mm<=d-2r<=80mm. Limiting steps are arranged on the sides of each first roller and the sides of each second roller. The guide roller has the advantage of being capable of effectively preventing the conveyer belt from deflecting.
Description
Technical field
The utility model relates to the vehicle for construction technical field, especially relates to a kind of guiding roller.
Background technology
The guiding roller is used for the carried and transported band.But, conveyer belt in the running, sideslip very easily if can not in time correct, then not only bad for the conveying of material, and can make the avris of this conveyer belt be subjected to the friction of miscellaneous part, has finally reduced its service life.
The utility model content
The purpose of this utility model provides a kind of guiding roller, and it has the advantages that effectively to prevent the conveyer belt sideslip.
The technical scheme that the utility model adopts is: the guiding roller, be used for preventing the conveyer belt sideslip, this guiding roller comprises roll body, described roll body cooperates in groups, comprise first rod and second roller in every group of roll body, be equipped with spiral bar on the surface of this first, second roller, and the lip-deep spiral bar hand of rotation of this first, second roller is opposite.
R is identical in the roller of described first, second roller footpath, and between the axial line of this first, second roller apart from d is: 30mm≤d-2r≤80mm.
Between the axial line of described first, second roller apart from d be: d-2r=50mm.
The avris of described first, second roller is equipped with limited step.
The utility model is compared the advantage that has with prior art: can effectively prevent the conveyer belt sideslip.Guiding roller of the present utility model distributes in groups, every group has 2 rollers, and roller is provided with spiral bar, this spiral bar initiatively makes this conveyer belt produce sideslip, but 2 spiral bar directions are opposite, correct thereby the sideslip that produces on the previous roller is carried out brute force, and then the sideslip that other factors are caused can ignore, guarantee the normal operation of this conveyer belt then.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is the birds-eye view of embodiment of the present utility model.
Among the figure: 10, roll body, 11, first rod, 12, second roller, 13, spiral bar, 14, limited step; 100, conveyer belt.
The specific embodiment
Embodiment, see shown in Figure 1: the guiding roller, be used for preventing conveyer belt 100 sideslips, this guiding roller comprises roll body 10, this roll body 10 cooperates in groups, comprise first rod 11 and second roller 12 in every group of roll body 10, be equipped with spiral bar 13 on the surface of this first rod 11 and second roller 12, and lip-deep spiral bar 13 hand of rotation of this first rod 11 and second roller 12 are opposite.Like this, by initiatively producing sideslip and correction, the sideslip of the conveyer belt 100 that other reasons causes can be ignored.
Optimize, the roller footpath r of this first rod 11 and second roller 12 is identical, and between the axial line of this first rod 11 and second roller 12 apart from d is: 30mm≤d-2r≤80mm.More excellent, between the axial line of this first rod 11 and second roller 12 apart from d be: d-2r=50mm.Like this, make first rod 11 and second roller 12 keep nearer distance as far as possible, thereby make its intervention to conveyer belt 100 more obvious.
Further, the avris of this first rod 11 and second roller 12 is equipped with limited step 14.Obviously, in the middle of the limited step 14 of these both sides is stuck in conveyer belt 100, further avoided the sideslip of this conveyer belt 100.
The above only is preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification sheets and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
