Abstract
The utility model discloses a steel stand-off device facilitating large-sized ribbed bar rolling and preventing piling-up of steel. The steel stand-off device comprises a horn guide pipe (1) supporting blocks (2), a steel stand-off guide pipe (3) and bases (5). The horn guide pipe (1) and the steel stand-off guide pipe (3) are fixedly connected and form a steel stand-off channel. The supporting blocks (2) are arranged on the steel stand-off guide pipe (3) through via holes. The bases (5) are arranged at the bottoms of both the supporting blocks (2) and are in immovable fitting with a guide and guard base (6) on a rolling mill rack. As the matched structure of horn guide pipe and the steel stand-off guide pipe is adopted, the rolling accident caused by impact of rolled pieces is eliminated; meanwhile, because the bases and the guide and guard base are matched through dovetail grooves, installation and replacement are easy and convenient. In this way, working performance is effectively enhanced, and unnecessary personal safety accidents are avoided. Besides, the steel stand-off device is simple in structure, safe and quick in use, reliable in work and convenient to install.

Background technology
The rolling of the above large sized ribbed reinforcing steel bar of Φ 36mm will be one of emphasis research and development product of steel industry with exploitation.In building trade, in order to improve the security of building, major project, large specification, high-strength hot rolled ribbed steel bar are generally adopted.Particularly in railway, dam and great infrastructure, large specification, high strength cast iron are more and more adopted.Existing rolling large-size Ribbed Bar because of rolling pass few, need sky to cross frame many, conventionally adopted steel conduit (groove) to replace the empty frame of crossing, but the method generally adopting is at present the method for designing that making support carries out supporting tube (groove), this design is in the operation of rolling, unstable, easily cause rolled piece to rush conduit (groove), there is heap steel and cause equipment and personal safety accident.
For this reason, research and develop and a kind ofly can directly be assemblied in the device on milling train, simple in structure, safe and efficient, reliable operation, easy for installation, be with a wide range of applications.
Utility model content
It is a kind of simple in structure, safe and efficient that the purpose of this utility model is to provide, reliable operation, easy for installation prevent from piling steel while contributing to rolling large-size Ribbed Bar cross steel device.
The purpose of this utility model is achieved in that and comprises loudspeaker conduit, back-up block, mistake steel conduit and base; Described loudspeaker conduit and the excessively affixed steel passage that formed of steel conduit; Described back-up block was arranged on steel conduit by its via hole, and described base is arranged at each back-up block bottom, with the guide base plate immovable fitting in rolling-mill housing.
The utility model adopts loudspeaker conduit and crosses steel conduit fit structure, and in use safety and stability, can not pile steel and cause equipment and personal safety accident, safe and efficient; Compared with prior art, in the operation of rolling, because frame has clamping hydraulic cylinder and locked hydraulic cylinder, cross steel device and be fixed in frame, therefore rolling is stable; Steel device was directly installed hanging in the process of changing, and was hung and change conveniently; Effectively reduce or stop rolling accident, improving efficiency.The utility model is simple in structure, safe and efficient, and reliable operation is easy for installation.
Brief description of the drawings
Fig. 1 is that the utility model duty master looks schematic diagram;
Fig. 2 is Fig. 1 cut away left side view;
In figure: 1-loudspeaker conduit, 2-back-up block, 3-crosses steel conduit, 4-rolled piece, 5-base, 6-guide base plate.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, but never in any form the utility model is limited, and any conversion or the improvement done based on the utility model training centre, all fall into protection domain of the present utility model.
As shown in Figure 1 and 2, the utility model comprises loudspeaker conduit 1, back-up block 2, crosses steel conduit 3 and base 5; Described loudspeaker conduit 1 and the excessively affixed steel passage that formed of steel conduit 3; Described back-up block 2 was arranged on steel conduit 3 by its via hole, and described base 5 is arranged at each back-up block 2 bottoms, with guide base plate 6 immovable fitting in rolling-mill housing.
