Detailed Description

The objects, technical solutions and advantages of the present utility model will become more apparent by the following detailed description of the present utility model with reference to the accompanying drawings. It should be understood that the description is only illustrative and is not intended to limit the scope of the utility model. In addition, in the following description, descriptions of well-known structures and techniques are omitted so as not to unnecessarily obscure the present utility model.

The specific embodiment is as follows: referring to fig. 1, a return lifting structure of a track link plate conveyor comprises a return bracket 1, wherein cross beams 11 are arranged on two sides of the return bracket 1, four vertical beams 12 are arranged between the two cross beams 11, two ends of each cross beam 11 are provided with upright posts 13, when in use, the top ends of the upright posts 13 are connected with a box body plate of the track link plate conveyor, the return lifting structure further comprises two coaxial riding wheels 2, the riding wheels 2 are larger, so that the riding wheels can bear larger force and the track link plates have enough stress areas, two sides of the riding wheels 2 are provided with central shafts, the central shafts are rotationally connected with bearing blocks 3, a plurality of mounting holes 31 are arranged on the bearing blocks 3, a plurality of long holes 121 are arranged on the vertical beams 12, the extending directions of the long holes 121 are perpendicular to the axes of the riding wheels 2, and fixing bolts 32 penetrate through the mounting holes 31 and the long holes 121 and are connected with nuts so as to fix the bearing blocks 3 on the vertical beams 12. Because only one group of riding wheels 2 is stressed more, the riding wheels can always keep close contact with the crawler belt link plates, the riding wheels and the crawler belt link plates cannot collide with each other, and the generated noise is small. When the deflection adjustment is required (when the conveyor with the track link plates is manufactured or the conveyor runs for a long time, the axis of the riding wheel 2 may not be perpendicular to the running direction of the track link plates so that the track link plates are deflected, and therefore the axis of the riding wheel 2 is required to be perpendicular to the running direction of the track link plates), the fixing bolts 32 are loosened, then the axis of the riding wheel 2 is perpendicular to the running direction of the track link plates, then the fixing bolts 32 and the nuts are screwed, the efficiency is relatively high, and a certain riding wheel 2 can be independently adjusted.

Further, the vertical beam 12 is provided with rotating seats 122 at positions on two sides of the bearing seat 3, the rotating seats 122 are fixed, the two rotating seats 122 are respectively located on two sides of the axis of the riding wheel 2, the rotating seats 122 are rotationally connected with pushing pieces 4, the pushing pieces 4 are provided with threaded holes penetrating through two sides of the pushing pieces, the threaded holes are in threaded connection with jacking bolts 5, one ends of the jacking bolts 5 away from the heads of the jacking bolts are in contact with the side surfaces of the bearing seat 3 so as to adjust the positions of the bearing seat 3 in the extending direction of the long holes 121. Since the track link plate is pressed against the supporting roller 2, the supporting roller 2 is easily subjected to radial force (particularly, the supporting roller 2 is positioned at an inclined section), so that the supporting roller 2 is easily and greatly displaced and the orientation of the supporting roller 2 is not easily adjusted when the fixing bolt 32 is loosened, when the rotating seat 122, the pushing member 4 and the pushing bolt 5 exist, the fixing bolt 32 is firstly loosened, then the pushing bolt 5 at one side is loosened (to a certain extent) and the pushing bolt 5 at the other side is tightened so as to adjust the axis of the supporting roller 2 to be perpendicular to the running direction of the track link plate, and then the fixing bolt 32 and the nut are tightened, so that the offset adjustment is easier.

Specifically, the rotary seat 122 is provided with a cylindrical groove, the axis of the cylindrical groove is perpendicular to the upper surface of the vertical beam 12, and the lower end of the pushing member 4 is provided with a cylinder rotationally connected with the cylindrical groove.

It is to be understood that the above-described embodiments of the present utility model are merely illustrative of or explanation of the principles of the present utility model and are in no way limiting of the utility model. Accordingly, any modification, equivalent replacement, improvement, etc. made without departing from the spirit and scope of the present utility model should be included in the scope of the present utility model. Furthermore, the appended claims are intended to cover all such changes and modifications that fall within the scope and boundary of the appended claims, or equivalents of such scope and boundary.
