Conventionally, the guide device of a cooling bed run-in table for long steel for low speed rolling (15 m/s or less) is an upwardly open type of angle steel, and the products (long steel) inside the guide device are of the upwardly open type.
The structure is such that a kick-out device allows the product to fall from inside the guide onto the cooling floor.

があつた。 Further, in a guide device for a cooling bed run-in table of a high-speed long steel rolling facility, generally a semicircular fixed guide and a semicircular movable guide facing the fixed guide form a cylindrical guide by a closing mechanism, Although it meets this requirement as a guide for a run-in table for high-speed rolling of thin long steel at 15 m/s or more, the drive structure of the movable guide is generally complicated, especially the pins and bearings of the numerous link mechanisms. , rattling is likely to occur due to wear due to high-speed and highly critical rocking motion, and as a result of the cumulative rattling, the movable guide structure often has malfunctions in opening and closing, and the closure is incomplete. As a result, a gap occurs, and problems such as the narrow steel strip biting into the gap cause the steel bar to become clogged in the guide, which not only halts the subsequent rolling operation but also requires significant time loss in replacing the guide. There were drawbacks that resulted in huge losses.

A required number of frames 2 are arranged and fixed on the upper surface of the cooling bed 1 at equal intervals along the entire length of the cooling bed 1, and each frame 2
has a steep slope chute 3 at the lowest level, and a steep slope chute 3' of the next stage is in equal contact with the steep slope chute 3, and after providing a space above the steep slope chute 3, a fixed trough 4 in the shape of an upper cover of the gentle slope is provided. , 4 are fixedly installed across one set of the frames 2 at intervals.
A groove-shaped trough 5 which faces and closely opposes the fixed trough 4 is integrally constructed with an arm 6, and is divided into a plurality of parts at intervals of the above-mentioned pair of frames and arranged in series. The arm 6 is screwed onto a mounting beam 7, and an arm swing lever 8 and an arm drive lever 9 are fixedly attached to the mounting beam 7. It constitutes a structurally assembled movable trough a, which is swingably supported by a shaft 10 of a bracket 11 and by the arm drive lever 9.
is the interlocking lever 1 via the turnbuckle 12.
It is pin-coupled to 3. The interlocking movement lever 13
is fixed to an interlocking shaft 14, which is connected over the entire length of the cooling bed and supported by the frame 2 through bearings 15, 15. The driving position of the interlocking shaft 14 is provided approximately at the center of the cooling bed 1, and the drive shaft lever 16 fixed to the interlocking shaft 14 is pin-jointed to the free end 17 of the cylinder 18. This structure is fixed to a cooling bed.

するものである。 The movable troughs a, a arranged over the entire length of the cooling bed 1 simultaneously form a closed cylindrical run-in trough b by the upward movement of the cylinder, and after the product is ready for entry, the run-in trough b is closed.
In response to a signal indicating that the product 20 has entered and stopped, the air cylinder 18 moves downward, and the movable trough a moves the product 20 in the groove-shaped trough 5 to the steep slope chute 3 while the movable trough a is descending. The product 20 falls from the steep slope chute 3 into the first groove 22 of the straightening table 21 of the cooling bed 1. With the above operation, the movable trough a moves to the steep slope chute 3.
The opening operation is completed by positioning the cylinder 18 at a lower position, but the cylinder 18 is raised within the time for the next product to enter, and the open movable trough c returns to the closed movable trough a, and the next step is carried out. However, the above operation is performed by the same mechanism from the next stage to the top stage.

The present invention provides the following effects.
The weight balance of the movable trough a is arranged so that both edges of the upwardly facing groove-shaped trough 5 press against the lower surface of the fixed trough 4, with the movable trough a having a one-piece structure being pivotally supported by the shaft 10 in a freely hanging manner. Due to the selection of the pivot point of the shaft 10 that is extremely critical and high-speed, repeated opening and closing operations can cause gaps (backlash) due to wear of many movable joints, including the pivot point of the shaft 10, and cumulative Even if the movable trough a is opened and closed, it does not immediately interfere with the opening and closing operation of the movable trough a.

中止する如きトラブルが発生しない。 Both ends of the groove-shaped trough 5 of the movable trough a are
Since the closed cylindrical trough b is always formed in close contact with the lower surface of the upper lid-shaped fixed trough 4 and can be maintained, there is no possibility that thin products will get caught in the trough gap and cause a clogging phenomenon, or that it will slip out. Therefore, troubles such as stopping the subsequent rolling process will not occur.
