Description

[Detailed description of the invention] The invention relates to a steel billet conveying device, and more specifically,
This invention relates to a steel billet conveying device in which a roller table section is provided with a heat shielding device for a rope of a rope transfer used when moving cold slab slabs on a skid onto a roller table for conveying hot and cold slabs.

Conventionally, hot slabs and cold slabs are sometimes conveyed alternately on one roller table.

In that case, for example, continuously cast high-temperature steel billet slabs are fed from another roller table installed perpendicularly to this roller table at the end of the roller table, or transported by a crane or the like. After that, it is transported on a roller table.

On the other hand, the cold piece slab is pushed by a skid car pulled by a rope on a fixed skid installed perpendicularly to the roller table in the middle of the roller table, and is transferred onto the roller table. transported by

However, in such equipment, the rope that pulls the skid car for transferring cold slabs is placed across the roller table, so when the hot slabs are transferred over the roller table, the rope is exposed to heat. One of the slabs may be burnt or its strength may be significantly reduced, causing problems in conveyance work and also being dangerous.

To this end, it is conceivable to provide a heat-insulating fixed cover above the rope in the roller table section where the rope traverses, where it will not interfere with the transfer of the slab.

However, on the other hand, in order to reliably transfer the cold slab slab to the center of the roller table by the skid car, it is necessary to insert the tip of the skid car on the roller table side into the roller table by about 3 minutes across the width of the roller table. The heat insulating cover cannot be installed in the area where the skid car enters.

Therefore, at the portion of the roller table into which the skid car enters, the rope for the skid car is exposed and burned by the hot slab when the hot slab is transferred.

The present invention was developed to eliminate the above-mentioned drawbacks of the conventional technology.It prevents the rope for moving the skid car from being exposed to the high heat of the hot slab at the roller table, and prevents damage to the rope etc. due to heat. It is an object of the present invention to provide a billet conveying device configured to prevent the above.

In the present invention, in order to achieve the above object, the steel plate of the fixed cover is placed above the rope for moving the skid car, which is located on the table part of the billet conveying device that pushes the steel billet with the skid car and transports it from the fixed skid to the table. A movable cover that can be pushed by a skid car is installed between the single loading side and the lower side of the fixed cover, and a return force adding device is installed to constantly apply force in the direction of the steel billet loading side of the movable cover. structure was adopted.

Hereinafter, the present invention will be explained in detail based on embodiments shown in the drawings.

Figures 1 and 2 are for explaining one embodiment of the present invention. In the figures, the reference numeral 1 indicates a fixed skid for moving steel pieces, and a plurality of fixed skids 1 are provided in parallel. A plurality of guide rails 2 are provided in parallel with these. The plurality of guide rails 2 are arranged in upper and lower directions as shown in Fig. 2.
The skid car 4 has two guide plates 2a, and a skid car 4 is mounted between these guide plates 2a via wheels 3, 3 so as to be freely movable. Each of the skid cars 4 has a protruding piece 4a, which pushes and moves a steel slab S, which is a cold slab placed on the fixed skid 1. A roller table 5 is provided at the end of the fixed skid 1 in a direction perpendicular to the pass line at the same level as the fixed skid 1 which is one step higher than the guide rail 2. The roller table 5 consists of a large number of rotatable rollers 5a, and fixed covers 6 are arranged above the guide rails 2 between these rollers 5a. The skid car 4 is inserted between the rollers 5a to some extent so that it can fully push the steel slab S, which is a cold slab, to the center of the roller table 5.For this purpose, the fixed cover 6 is placed between the rollers 5a to a certain extent. Only about two-thirds of them are provided.

A movable cover 7 is arranged below the fixed cover 6 and is fixed to a cart 8. A truck 8 is mounted on the guide rail 2 so as to be freely movable via wheels 9, and a pulley 11 is rotatably supported on the lower end of the truck 8 via a bracket 10. A wire 12 whose one end is fixed to a bracket 8a near the front end of the cart 8 is wound around the pulley 11, and the other end of this wire 12 is wound around a sheave 14 via a roller 13, and the wire 12 The other end is fixed to a bracket 2b on the lower surface of the tip of the guide rail 2. Sheave 14
is provided so as to be movable up and down along a guide groove 15a in a bracket 15 vertically attached to the guide rail 2, and a counterweight 16 is attached to the sheave 14 in a suspended manner.

Therefore, the wire 12 is always pulled by the counterweight 16, and a moving force is applied to the truck 8 and the movable cover 7 in the direction of exiting from under the fixed cover 6 to the rear.

Reference numeral 17 denotes a drum that runs an endless rope 18 that connects the front and rear ends of the skid car 4, and is rotated by a motor (not shown) to move the skid car 4 back and forth.

Next, the operation of this embodiment configured as above will be explained.

When the skid car 4 does not push the steel slab S, which is a cold slab, the movable cover 7 is located at the backward limit and protrudes from the fixed cover 6 to the maximum extent because the counterweight 16 is lowered. be. At this time, when the heated slab is transferred on the roller table 5, the movable cover 7 is transferred to the fixed cover 6.
At the same time, the rope 18 for the skid car 5 has a heat-insulating effect.

When transferring the cold piece slab S on the fixed skid 1 onto the roller table 5, in this state, the rope 18
When the skid car 4 is moved clockwise in FIG. 2, the skid car 4 moves forward while pushing the rear end of the steel piece S with the protruding piece 4a. Then, the tip of the protruding piece 4a pushes the rear end of the movable cover 7, so the movable cover 7 moves forward and pushes the count weight 1 toward the lower side of the fixed cover 6.
It is pushed against the weight of 6. At this time, the sheave 14 with the count weight 16 suspended thereon rises to the upper position shown by the two-dot chain line in FIG. When almost the entire movable cover 7 is placed under the fixed cover 6, since the fixed skid 1 and the roller 5a are at the same level, only the steel piece S is transferred onto the roller 5a.

FIG. 3 illustrates another embodiment of the present invention, in which the same or corresponding parts as in FIGS. 1 and 2 are given the same reference numerals.

This embodiment differs from the above-described embodiments in that a spring 19 is used instead of a counterweight as a return force applying device for the movable cover 7.

That is, the bracket 2 provided on the lower surface of the truck 8
A spring 19 is stretched between the movable cover 7 and a bracket 21 protruding from the lower surface of the guide rail 2, which applies a return force to the movable cover 7 in the direction away from the fixed cover 6. There is. Since the spring 19 is covered by the cover 22, there will be no chance of other members coming into contact with each other when the spring 19 expands or contracts.

As is clear from the above explanation, according to the present invention, a movable cover that can be pushed by a skid car is slidably provided between the position where the steel billet is carried in and the position where it is accommodated under the fixed cover. Since the structure is equipped with a return force adding device that constantly applies force in the direction of the billet loading side of this movable cover, when the hot billet moves on the roller table, the heat of the billet is absorbed. is shielded by fixed and moving covers, and the rope is not damaged by heat. Therefore, the transportation work is not hindered and is safe.

Additionally, when transferring cold slab slabs onto the table using a skid car, the moving cover is pushed by the skid car and goes under the fixed cover, making it possible to reliably transport the cold slab slabs to the center of the table. .
