Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a skid structure of a walking beam type cooling bed for cooling hot rolled steel products.

Generally, hot-rolled flat steel, shaped steel, round bars, and square billets are cooled in a walking beam type cooling bed depending on the characteristics of the cross-sectional shape of the material to be cooled.

The shape of the upper surface of the skid in this walking beam type differs depending on whether the object to be conveyed (material to be cooled) is flat steel or section steel or when conveying a round bar or square billet.

In other words, in the case of flat steel and shaped steel, the mounting surface is flat, whereas in the case of round bars and square billets, the surface on which they are placed is arcuate and angular, making it difficult to place them stably. In order to provide an appropriate gap between the materials to be cooled and to prevent slipping and meandering, the skid surface must be formed into a V-shaped groove.

Furthermore, even for round rods, if the range of rod diameter sizes is wide, if V-shaped grooves of equal pitch are used, there is a problem that the cooling capacity of the cooling bed will be reduced for small diameter round rods. (Because the loaded weight is reduced) In order to satisfy these requirements, there are two types of cooling beds: one with a flat top surface and the other with a V-shaped groove on the top surface and the pitch of the V-groove is variable. It is necessary to have more than one cooling bed.

Therefore, as a result of studies in view of the above-mentioned conventional circumstances, the present invention has been developed to provide a fixed skid and an elevating skid having a V-shaped groove for placing round bars and square billets.
It is also equipped with a flat lifting skid with a flat top surface for placing flat steel and shaped steel, and a walking beam type cooling bed with variable pitch of V-shaped grooves to improve the loading efficiency of small diameter round bars. The skid structure is obtained, and its purpose is 1.
The objective is to be able to meet the above requirements with a surface cooling bed.

The present invention will be described in detail below with reference to drawings showing specific examples of implementation.As shown in FIGS. The movable bed 1 has a skid structure 3 on the upper surface of the movable bed 1.
... are placed on the lifting beam 4, which is placed in contact with the support rollers 5, via the balls 6, and the cylinder rod 7 is moved in the direction of the arrow a in FIG.
Or, by moving in the opposite direction of arrow a, the lifting beam 4 is moved up and down, and the moving floor 1 is moved up and down together with the fixed beam 2, and furthermore, the moving bed 1 is pivoted on the support 8. The upper end of the lever 9 is connected by engagement with the pin 10 and the elongated hole 11, and by operating the cylinder rod 12, which connects the lower end of the lever 9, in the direction of the arrow b in FIG. It is designed to be horizontally moved in the c direction. On the other hand, the fixed bed 30 is immovably fixed, and a skid structure 3' for receiving and placing the material to be cooled from the movable bed 1 when the movable bed 1 is lowered is provided above the skid structure 3' of the movable bed 1. It has a similar configuration. (Hereinafter, the constituent members of the skid structure 3' of the fixed bed 30 will be denoted by the same symbols as the constituent members of the skid structure 3 of the movable bed 1, with the suffix '.')
