Abstract

The utility model relates to an idler wheel structure, which comprises an idler wheel (1) and an idler wheel shaft (2), wherein a surface of the idler wheel is U-shaped; the idler wheel (1) is connected with an idler wheel seat (3) through the idler wheel shaft (2); the idler wheel seat (3) is fixed on a base (4) through a connecting bolt (5); a square hole is arranged in the bottom part of the idler wheel seat (3); a slope is arranged on an upper surface of the base (4); and a square hole is arranged in the bottom part of the slope. The idler wheel structure is simple, the processing difficulty and the processing cost are reduced, and the installation and the maintenance are convenient.

Description

Roller structure

Technical field

The utility model relates to mechanical field, relates to the roller structure that a kind of cylindrical shell sandblast is sprayed paint specifically.

Background technique

In the working process of wind-power electricity generation wind tower cylindrical shell; The processing of different operations such as need carry out surface sand-blasting to cylindrical shell, spray paint; Because roller contacts the damage that can cause workpiece surface with cylindrical shell in sandblast, the process of spraying paint; So in the actual fabrication process, contact with workpiece for fear of roller, generally need two sections supplemental cartridge of special making to save and be connected the workpiece two ends, as the supporting surface use of pair of rollers workpiece.But because the workpiece diameter excursion is bigger, often need be according to the auxiliary shell ring of the frequent conversion of the variation of workpiece, so the fabricating cost of auxiliary shell ring is very high.

In order to address the above problem, also can be reduced to form of flanges, thereby can to make a big specification auxiliary flange, thereby satisfy the connection user demand of all specification cylindrical shells assisting shell ring to shorten.But owing to have a certain amount of axial float in the Workpiece Rotating process; Adopt behind the auxiliary flange because contact width is little; Be easy to occur, even the danger of surface of contact landing can occur supporting, finally can influence the spraying effect of cylindrical shell because play causes the surface of contact changing of the relative positions.In addition because in the sandblast process, the sand material can be deposited in the structure slit of back-up roller wheel carrier, causes equipment failure and damage.

The model utility content

The problem that the utility model will solve provides and a kind ofly can under sandblast, special operation condition such as spray paint, satisfy usage requirement, reduces difficulty of processing and cost, and makes things convenient for the roller structure of installation and maintenance.

The purpose of the utility model realizes through following technological scheme:

Roller structure; Comprise roller 1 and roller shaft 2, said roller surface is the U type, and said roller 1 is connected with roller base 3 through said roller shaft 2; Said roller base 3 is fixed on the base 4 through connecting bolt 5; Square opening is arranged at said roller base 3 bottoms, and said base 4 upper surfaces have the slope, and bottom, said slope has square hole.

Said base 4 upper surface longitudinal sectional drawings are in the shape of the letter V.

The beneficial effect that the utility model can be realized is:

1), simple and compact for structure, stable and reliable operation;

2), with low cost;

3), working service is convenient.

Description of drawings

To combine accompanying drawing to come the utility model done below further describes.

Fig. 1 is the roller overall structure schematic representation of the utility model;

Fig. 2 is the U type wheel construction schematic representation of the utility model;

Fig. 3 is the roller base structural representation of the utility model;

Fig. 4 is the understructure schematic representation of the utility model;

Wherein, 1U type roller, 2 roller shafts, 3 roller base, 4 bases, 5 connecting bolts, 6U type groove, 7 square holes, 8V font.

Embodiment

For the beneficial effect of more properly describing the utility model and being brought, will combine accompanying drawing that the utility model is done below and further describe, but the protection domain of the utility model is not limited to the content that embodiment is explained.

In conjunction with Fig. 1; A kind of novel roller structure of the utility model; Comprise compositions such as U type roller 1, roller shaft 2, roller base 3, connecting bolt 5, base 4, U type roller 1 is connected with roller base 3 through said roller shaft 2, and roller base 3 has played the supporting effect to U type roller 1; U type roller 1 can be rotated around roller shaft 2, satisfy driving or following the functional requirement that workpiece rotates.Roller base 3 is fixed on the base 4 through connecting bolt 5.

Can find out in conjunction with Fig. 2; U type roller 1 surface is the U type, and U type roller surface shape is similar to letter U and has formed a kind of U type groove, in use; Auxiliary flange is placed in the U type groove 6; The supporting effect to auxiliary flange and workpiece weight is played in U type groove 6 bottoms, and the dual-side of U type groove 6 has played left and right sides position-limiting action to pivot flange, has avoided the axial float phenomenon of workpiece in rotary course.Utilize the characteristics of three location of U type, reduce cost satisfying under the prerequisite of usage requirement.

In conjunction with Fig. 3, roller base 3 bottoms are provided with bigger square hole 7, thereby can guarantee the phenomenon that seepage is got off from the slit sand material can not occur piling up.

In conjunction with Fig. 4, base 4 upper surface longitudinal sectional drawings are in the shape of the letter V 8, and the bottom, slope has square hole 7, make that the sand material in the roller base can flow out from the square hole 7 of bottom smoothly, easy-to-operat worker cleaning.Utilize the sand material to have mobile characteristics, structure drift sand passage is guided to device external naturally with the sand material that leaks in the device structure.
