Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Example 1

Referring to fig. 1-3, a frame of a turning belt conveyor comprises upright columns 1, which are consistent with the prior art, wherein the upright columns 1 on two sides are connected by cross bars 2, a plurality of groups of upright columns can be connected by trusses to form the frame of the conveyor, and trusses arranged in an inverted trapezoid are connected with each other to form a turning section as an improved part, in the scheme, a main support rod 3 is arranged above the cross bar 2, the main support rod 3 is used for installing a roller frame, one end of the main support rod 3 is hinged with the cross bar 2 through a first shaft 100, and the other end of the main support rod 3 is hinged with an auxiliary support rod 4 through a second shaft 200; the upper portion of horizontal pole 2 rotates and is provided with threaded rod 5 rather than parallel, and threaded rod 5 is equipped with slide 6, and slide 6 and threaded rod 5 screw-thread fit, and when the threaded rod rotated, slide 6 slided along threaded rod 5. The sliding seat 6 is hinged with the auxiliary supporting rod 4 through a third shaft 300, when the sliding seat moves, the supporting angle of the auxiliary supporting rod changes, and the height of the main supporting rod changes along one end connected with the auxiliary supporting rod, so that the adjustment of the lifting angle is realized; the first shaft 100, the second shaft 200 and the third shaft 300 are parallel to each other and vertical to the upright; the two sides of the sliding seat are provided with rollers 7, the upper part of the cross rod 2 is provided with a slideway plate 8, the rollers 7 are arranged on the slideway plate 8 in a sliding way, and the sliding seat 6 is not contacted with the slideway plate 8. Because the slide does not contact with the slide way plate, only friction between the slide and the threaded rod is generated when the slide moves, and because of the support of the roller wheels, the belt bearing is completely born by the roller wheels, the threaded rod cannot be extruded, so that the friction resistance between the slide and the threaded rod can be reduced, and the threaded rod can be prevented from deforming.

As an improved scheme, one end of the slide way plate 8 in the scheme is hinged with the cross rod 2 through a fourth shaft 400, the fourth shaft 400 is parallel to the upright column, and the fourth shaft 400 and the first shaft 100 are positioned on the same side; the other end of the slide way plate 8 is provided with gear teeth 9, the gear teeth 9 take the fourth shaft 400 as the center of a circle, the cross rod 2 is provided with an adjusting gear 10 meshed with the gear teeth 9, and the adjusting gear 10 is provided with a locking nut; the first shaft is connected to the slide way plate. Therefore, the adjusting gear is rotated to drive the slide way plate to rotate around the fourth shaft, so that the deflection angle of the carrier roller is adjusted, and the locking nut is screwed after the carrier roller is adjusted in place.

As another improvement, the slideway plate 8 in the scheme is provided with a V-shaped sliding groove 11, and the roller is positioned in the sliding groove. The V-shaped sliding groove 11 can play a role in guiding, so that the lateral extrusion force is prevented from being generated, and the deformation of the threaded rod due to the lateral extrusion force is further avoided.

In addition, in the scheme, a locking rod 12 is arranged on the sliding seat 6, a bolt connecting end 13 is arranged at the lower end of the locking rod 12, a locking groove 14 is formed in the cross rod, and the bolt connecting end is embedded in the locking groove. And after the sliding seat is adjusted to a proper position, the nut of the threaded connection end is screwed and fixed. In accordance with the above improvement, in the embodiment, the locking groove is provided on the slide plate on the cross bar.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
