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. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art all belong to the protection scope of the present invention.
The embodiment of the utility model provides a:
as shown in fig. 1, the lifting auxiliary roller replacing device comprises a support plate 1, a lifting mechanism, a lifting frame 2 and a support frame 3; the supporting plate 1 is positioned above the lifting frame 2 and connected with the lifting frame 2 together for supporting a belt; the support frame 3 is positioned below the lifting frame 2 and is used for supporting the ground; the lifting mechanism comprises an anchor rod and a nut for controlling lifting; one end of the anchor rod is connected with the support frame 3, and the other end of the anchor rod penetrates through the lifting frame 2; the nut is sleeved on the screw rod and is positioned between the support frame 3 and the lifting frame 2; the left and right intervals of the lifting mechanism are provided with two groups, and the nut is rotated in the same rotating direction, so that the lifting frame 2 can move up and down, a belt on the carrier roller is supported, and the carrier roller is convenient to replace.
The lifting frame 2 is of a rod-shaped structure with a rectangular cross section, and the middle part of the lifting frame is a cavity, so that the strength is ensured, and meanwhile, materials are saved. The lifting frame 2 is arranged at the left and right sides in the length direction. The crane 2 is located the whole below of backup pad 1, and length direction is unanimous with backup pad 1, under elevating system's effect, can reciprocate along with backup pad 1, because backup pad 1 is domes, is difficult for cooperating with elevating system, so specially establish this crane 2, solved backup pad 1 promptly difficult with elevating system complex problem, also guaranteed the stability of whole device simultaneously.
