Description

Quick deviation correcting device of belt

Technical Field

The utility model relates to a quick deviation correcting device of belt belongs to belt transport machinery corollary equipment.

Background

The belt deviation correcting device is widely applied to belt conveyors and stacker-reclaimers in mines, metallurgy, power plants, coal yards, gathering stations, port docks and the like. The principle of belt deviation correction is that after a belt deviates, a deviation correcting device deflects to a specific direction, so that the belt and the deviation correcting device slide, and the deviation correction of the belt is realized through friction force. However, the existing belt deviation rectifying devices generally have the defects of unreasonable structure, slow response and the like, and how to improve the sensitivity of the deviation rectifying device and quickly and effectively realize deflection response is a technical problem to be solved urgently.

Disclosure of Invention

An object of the utility model is to improve prior art's weak point, provide a novel structure's quick deviation correcting device of belt.

The technical scheme of the utility model is that: the utility model provides a quick deviation correcting device of belt, including upper bracket and lower carriage, the lower carriage includes the lower carriage main part, be equipped with the pivot mount in the lower carriage main part, the central point of pivot mount puts and is equipped with the pivot, the upper bracket includes the upper bracket main part, be provided with parallel bearing roller in the upper bracket main part, slant swing joint has the guide roll support respectively at the both ends of upper bracket main part, be equipped with the direction bearing roller on the guide roll support, the upper bracket main part of upper bracket and the pivot swing joint of lower carriage, characteristics are, be equipped with N parallel bearing roller installation position that is used for installing parallel bearing roller in the upper bracket main part, N > 2, N parallel bearing roller installation position is the symmetric distribution for the central line, the guide roll support at upper bracket main part both ends is the symmetry respectively and is equipped with M, M is greater than or equal to 2, M guide roll.

The belt deviation correcting principle is realized through friction force, namely when a deviated belt passes through a carrier roller of the deviation correcting device, the friction force generated between the deviated belt and the carrier roller causes the deviation correcting device to twist so as to realize deviation correction of the belt. However, the guide carrier roller of the lateral vertical surface of the existing deviation correcting device is either a big-end type friction guide wheel, is light in weight, or is a single-roller type conical carrier roller structure, and in any structure, although the structure has a certain deflection response, the guide carrier roller is only in short contact with a belt during operation, so that the phenomenon that the guide carrier roller does not timely sense the deviation of the belt and does not generate torsion when the belt passes through the guide carrier roller often occurs, and the deviation correcting effect cannot be achieved at all. Compared with the prior art, the utility model discloses a structural feature lies in the overall arrangement of redesign bottom parallel bearing roller and side direction bearing roller, the adjustment has increased the installation bit architecture of bottom parallel bearing roller and side direction bearing roller, not only can effectively increase the area of contact with the belt, increase beneficial frictional force, when the belt passes through a plurality of side direction bearing rollers, can also make the side direction bearing roller feel the direction of deflection of belt more surely, increase perception ability, make deviation correcting device more sensitive, fast, realize the deflection response effectively, improve the tuningout effect.

The present invention will be explained in detail with reference to the drawings and examples.

Detailed Description

Referring to fig. 1 to 6, the belt rapid deviation rectification device of the present invention comprises an upper bracket 1 and a lower bracket 2, the lower bracket 2 has a structure substantially the same as that of the existing device, and comprises a lower bracket main body 9, both ends of the lower bracket main body 9 are connected with an intermediate bracket fixing plate 8, a rotating pivot fixing frame 10 is arranged on the lower bracket main body 9, and a rotating pivot 11 is arranged at the center of the rotating pivot fixing frame 10; the upper bracket 1 comprises an upper bracket main body 5, as shown in fig. 2 and 4, three parallel carrier roller mounting positions 12 which are symmetrically distributed relative to a central line are arranged on the upper bracket main body 5, parallel carrier rollers 4 are respectively mounted on the three parallel carrier roller mounting positions 12, guide roller brackets 6 are respectively movably connected to two ends of the upper bracket main body 5 through bolts, the guide roller brackets 6 are obliquely arranged, two guide roller brackets 6 are respectively mounted at two ends of the upper bracket main body, the two guide roller brackets 6 are symmetrically distributed relative to the central line, a guide carrier roller 3 is mounted on each guide roller bracket 6, an angle adjusting screw 7 can be further arranged on each guide roller bracket 6, and the guide carrier rollers 3 are inclined by a proper angle through adjusting the angle adjusting screw 7 so as to adjust a deviation correcting angle and increase a guide force and a deviation correcting force; the whole upper bracket 1 is movably connected with a rotating pivot 11 of the lower bracket 2 through the upper bracket main body 5.

When the automatic deviation correcting device works, the bottom of the automatic deviation correcting device adopts three parallel carrier rollers to carry the belt, the contact area between the belt and the belt is increased, the bearing capacity and the stability are improved, the friction force between the belt and the bearing capacity is correspondingly increased, and the deviation correcting effect is assisted to be improved. Because the lateral guide carrier rollers are mainly used for bearing the deviation correction of the belt, the lateral guide carrier rollers adopt a double-roller structure, the lateral guide carrier rollers not only have the function of increasing the contact area and the friction force with the belt, but also can enable the lateral guide carrier rollers to accurately sense the deflection direction of the belt for a plurality of times when the belt sequentially passes through a plurality of lateral guide carrier rollers, increase the sensing capability, timely adjust the left rotation or the right rotation of the device, enable the deviation correction device to more sensitively, quickly and effectively realize deflection response and improve the deviation adjustment effect.

The utility model discloses a plurality of can be reserved to the installation position of parallel bearing roller in bottom and side direction bearing roller when the design, but quantity overall arrangement will be in time adjusted according to belt actual load and functioning speed during practical application to it is more better, adjust to the response sensitivity of deflecting can fast.
