Plate blank positioning device for transverse-moving trolley

Abstract

The invention discloses a plate blank positioning device for a transverse-moving trolley. The plant blank positioning device comprises conveying rollers, a linked shaft lever, supporting bases, a guide wheel mechanism, a return block, induction iron plates and proximity switches, wherein the proximity switches are connected with an operation system PLC (programmable logic controller) through cables; two supporting bases are arranged between the two conveying rollers at the output ends of a conveying roller way, and are respectively fixed with the two ends of a frame; the linked shaft lever passes through shaft holes in the two supporting bases, the two ends of the linked shaft lever are fixed with the induction iron plates, and the guide wheel mechanism is fixed between the two induction iron plates; the return block is fixed below the guide wheel mechanism; and the proximity switches which correspond to the induction iron plates are arranged on outer side surfaces of bottom plates of the supporting bases. The plate blank positioning device is simple in structure, easy to manufacture and mount, accurate in positioning, free from influence of a high-temperature environment, safe and reliable and long in service life, and maintenance update cost is reduced.

Description

technical field [0001] The invention relates to a continuous casting slab positioning device, in particular to a slab positioning device for a traverse trolley. Background technique [0002] The existing steelmaking to steel rolling system adopts a short process, that is, the continuous casting machine blank conveying roller table of the steelmaking system is docked with the heating furnace conveying roller table of the steel rolling system to achieve high efficiency. When the slab continuous casting machine has two streams or multiple streams in one machine, it is necessary to set up a traverse trolley. The function of the traversing trolley is to carry each stream of slabs after cutting, and move them traversingly to the conveying roller table leading to the rolling system for docking, so as to realize the barrier-free conveying of slabs. The slab coming out of the continuous casting machine is moved to the traverse trolley, which needs to be positioned safely and accurat...

AI Technical Summary

Problems solved by technology

The slab coming out of the continuous casting machine is moved to the traverse trolley, which needs to be positioned safely and accurately, otherwise safety accidents will occur and production will be affected

At present, the positioning process of moving the slab to the traversing trolley is through the beam-type laser detector. When the slab is running on the traversing trolley, the jitter is very large, and it is easy to send false action signals, which is not stable. In addition, the rollers are all It is to transport hot blanks, and the temperature is very high. In such an environment, the electronic components of the laser detector are frequently damaged, which virtually increases the production cost of the enterprise.
