Description

[Detailed Description of the Invention] The present invention relates to a brake device in a long steel rolling facility.

In long steel rolling equipment, the rolled long steel (rolled material) is cut into desired lengths by a split shear after exiting the final finishing mill, and then conveyed to the cooling bed at the same rolling speed. The stopping of rolled material on the cooling bed run-in conveyance path is mainly caused by braking due to natural friction between the rolled material and the conveying surface, and the braking sliding distance varies depending on the type of rolled material, so a long conveyance path is required. However, a large area of land must be allocated for this conveyance equipment, and this poses a problem in that it cannot cope with the increase in rolling speed.

For this reason, in recent years, the above problem has been solved by applying forced braking to rolled steel strips on the conveyance route, but the brake devices conventionally used for this forced braking only have a braking function. Since it is simply a brake device, it must be inserted between the guide passages that make up the conveyance path, and the disadvantage is that space for the brake device must be secured in the conveyance path. It was hot.

The present invention was made in order to eliminate the above-mentioned drawbacks of the conventional technology. Consisting of a brake guide member and an inclined guide,
When the guide member swings up and down, the entire guide member moves up and down with respect to the guide surface of the inclined guide, so that it forms part of the guide path that constitutes the conveyance path and exerts a braking action. The purpose of the present invention is to provide a braking device for rolling equipment for long steel products, which can efficiently apply braking to rolled steel products without increasing the length of the transport path, and which can shorten the length of the transport path compared to conventional methods. .

Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments.

In FIG. 1, reference numeral 1 denotes a horizontally extending guide member having a substantially V-shaped cross section as shown in FIG. Form. The guide member 1 is fixedly supported at a plurality of suitable positions on the horizontal limb end portion of the receiving lever body 2 whose side surface is substantially square-shaped. The receiving lever body 2 is swingably suspended from a support frame 3 at its vertical limb end by a pin 4, and is rotatably supported by a pin 6 at one end of a two-pronged connecting rod 5 at the bent part. By being connected and pressed toward the cooling bed rake device 7 by the connecting rod 5, the guide member 1 is supported such that its corner c is located above the guide surface 8a of the inclined guide 8. Reference numeral 9 denotes a fan-shaped lever plate, which is vertically pivoted at its main part to a support column 10 so as to be swingable by a pin 11, and whose lower corner part is connected to the other end of the connecting rod 5 by a pin 12; Further, the upper corner portion is connected to the piston rod of the drive cylinder 13 and pulled toward the drive cylinder 13 side. The drive cylinder 13 is in a substantially horizontal state and its base is swingably supported by a column 14. The inclined guide 8 is arranged between adjacent guide members 1.
For example, it is supported by supports (not shown) so as to be inclined downward toward the cooling bed rake device 7.

Reference numeral 15 denotes a horizontally extending brake guide member, which has an inverted V-shaped cross section and includes a brake shoe portion 16 and a guide portion 17 as shown in FIG. In between, a tubular passage 18 is formed in which the side end surface of the shoe portion 16 is in substantially abutment with the guide surface of the guide member 1, and the one side end surface of the guide member 1 is in a state in substantially abutment with the guide portion 17, It is fixedly supported by the rocking body 19 at a plurality of suitable locations (two locations in this example). The rocking body 19 has an upper part supported by a support frame 20 so as to be rockable, and a lower part formed by a connecting rod 21 having two prongs at both ends and extending rearward in a substantially horizontal direction.
The connecting rod 2 is connected to one end of the connecting rod 2 by a pin 22.
1 supports the brake guide member 15 so that the tubular passage 18 is formed by being pressed toward the cooling bed rake device 7 side. Reference numeral 23 denotes a lever body, which has a pair of connecting pieces 2 erected on each of the upper and front surfaces of the horizontal arm 24 extending in a direction perpendicular to the longitudinal direction of the connecting rod 21, that is, in the longitudinal direction of the guide member 1.
5, 26, and a connecting piece 27 erected at the longitudinal center of the lower surface. The lever body 23 is located behind the swinging body 19 and has a pair of connecting pieces 25 on the top surface.
is connected to the support frame 29 by a coaxial shaft 28, so that it is swingably suspended from the support frame 29, and one end of the corresponding connection rod 21 can be rotated by a pair of connection pieces 26 on the front side. The connecting piece 26 on the lower surface is connected to the piston rod of the drive cylinder 30. 19-29 above
A drive cylinder 30 that drives a swinging mechanism consisting of
The base is pivotably supported on a support 14 so as to be substantially horizontal. The lever body 23 and the swinging body 1
9 and the connecting rod 21,
The front end surface of the shoe portion 16 of the brake guide member 15 moves downward to the bottom of the groove along the guide surface of the guide member 1, as shown by the chain line in FIG. 3, when the drive cylinder 30 moves backward. The drive cylinder 30 is a tip detection device (not shown) for rolled steel bars provided on the conveyance path.
The driving cylinder 13 is activated in response to a detection signal, and is timed so that the driving cylinder 13 is activated after a certain period of time defined by a timer.

The brake guide member 15 and its supporting drive mechanism are preferably arranged as a unit as shown in the figure so that the braking force can be easily changed.

For example, as shown in FIG.
In other words, the brake guide member 15 is supported and arranged with respect to the conveyance path 32 so that the tubular passage 18 is formed. The operation of the drive cylinder 30 is therefore synchronized with a drive (not shown) for driving the conveying path 32 down.
In actual rolling equipment, the run-in conveyance path is configured in a vertical multi-stage arrangement, so the brake device also has a multi-stage configuration in which it communicates with each stage conveyance path 32, respectively. In addition, in FIG. 4, 33 is a finishing rolling mill, 34 is a dividing shear, 35 is a line selector, and 36 is a guide pipe.

In the above configuration, the rolled material A distributed by the line selector 35 is conveyed to the cooling bed line-in conveyance path 32 via the brake device according to the present invention. At this point, the drive cylinder 30 is not activated, so that the tubular passage 18 formed by the guide member 1 and the brake guide member 15 allows the rolling stock A to pass freely.

When a rolled material tip detection device (not shown) provided at an appropriate location on the conveyance path 32 operates, the piston rod of the drive cylinder 30 that receives the detection signal retreats in the direction of the arrow shown in the figure, and the show surface a of the brake guide member 15
descends and presses the rolled material A against the guide surface b of the guide member 1. Since the shoe part 16 rotates downward so that its front end fits into the corner part c while substantially facing the guide surface b of the guide member 1, the rolled material A is vibrated vertically and horizontally due to high-speed running. Even if it is, it is restricted to the corner c and braked. Therefore, braking force is reliably applied to the entire length of the rolled material A within the space of the tubular passage 18 without losing its straightness. In this braking, since the shoe surface a is long, sufficient braking ability is exhibited even if the pressurized braking force per unit length is small. After a certain period of time after the above-mentioned pressing operation is started, the run-in conveyance path 32 rotates downward in order to discharge the rolled material, and in synchronization with this, the piston rod of the drive cylinder 13 moves in the direction of the arrow shown in FIG. The guide member 1 rotates downward as shown by the chain line in A. As a result, rolled material A, which had stopped after braking sliding,
are transferred to discharge guides and inclined guides 8 (not shown) provided at a plurality of suitable locations on the run-in conveyance path 32, and then dropped and carried into the rake device 7. At this time, since the inclined guide 8 is provided, one end of the rolled material A does not jump when falling, and the rolled material A is reliably carried into the groove of the rake device 7.

As described above, in the present invention, a braking system having a substantially inverted V-shaped cross section with a brake shoe surface is applied to a guide member having a V-shaped cross-section that can swing up and down, and which is a part of the guide path for rolled steel products. Since the guide members are arranged facing each other, there is no need to add them to the guide path as in the past, and they can be replaced with part of the guide path, so the length of the conveyance path is shortened compared to the past. It is possible to significantly reduce the cost required for transportation equipment. Furthermore, since the shoe surface swings up and down in the V-shaped space of the guide member, the guide member and the braking guide member can always apply an even and almost constant frictional braking force to the rolling rolled steel products. Braking efficiency can be obtained.
Furthermore, even if the diameter of the rolled steel strip is changed, reliable braking can be performed using the same device. Furthermore, since a tubular passage space is formed by the guide member and the braking guide member, if the guide passage is in the form of a gutter, it functions as a guide path for the rolled steel strips when braking is not applied, and the running speed of the rolled steel bars Regardless of the situation, there is an advantage that there are no problems such as problems such as splashing out of the conveyor line.
