As the wheel rotates by a driving motor (not shown), the carriage 13 reciprocates along the rail 11.

Therefore, when the slab S cut to a predetermined length is transferred to a roller table (not shown) of the horizontal table 10, a port cell (not shown) senses the slab S and the end of the slab When passing through the port cell, the roller table rotates in reverse to stop the feeding of the slab.

After that, in a state where the carriage 13 is raised and floated on the slab S on the horizontal table 10, as shown in FIG. 6, the cylinder 14 expands to form a triangular plate (under the bottom of the track 12) ( When P) is located at the upper end of the roller bearing L, the track 12 rises to a predetermined height, and the slab S on the horizontal table rises to a predetermined height as the carriage 13 rises in conjunction with this. Then, as the carriage 13 moves on the rail 11 by the wire W, the slab S transferred onto the horizontal table 10 is horizontally moved to the standby slab position for the subsequent process.

In addition, when the rod of the cylinder 14 is contracted, the triangular plate P of the track 12 slides down in the roller bearing L, and as the track 12 descends, the carriage 13 lowers and the slab is shown. It is conveyed to a subsequent process by the roller table which is not.

That is, when the carriage 13 of the horizontal table 10 detects the slab S on the roller table and the rod of the cylinder 14 expands, the track 12 rises and the carriage 13 moves on the horizontal table 10. It will rise higher than the upper surface of.

On the other hand, when the slab is transported due to the manual operation of the operator, if the slab to be transported collides with the raised carriage 13, the equipment accident that the carriage 13 is easily overturned from the rail 11 of the track 12 Occurs. In addition, when the slab is horizontally moved by the carriage 13 in a floating state, it collides with the preceding slab to be conveyed, and the carriage 13 is overturned and derailed from the rail 11 of the track 12 to cause an accident.

As a result, when the slabs produced are stagnated on the horizontal table and the slabs produced on the emergency bed are placed in the emergency bed due to the risk of casting stoppage and emergency, the slabs may lose information and the slabs may be bent. There is a risk of safety accidents such as burns, loss or fall of workers.

The present invention has been made in order to solve the above-mentioned conventional problems, and when the carriage is raised and collided with the slab being transported or the slab is floated horizontally to collide with the preceding slab and roll over from the rail of the track. It is an object of the present invention to provide a rollable horizontal table carriage for overturning with a shock absorber to prevent the engine from derailing.

The outer lower portion of the hopper 30 is made of a wide triangle base. A hopper link 32 having a hexagonal groove 32a through which the hexagonal shaft 34 penetrates is provided at the lower center of the triangle, and a square protrusion is formed at the lower portion of the triangle adjacent to one side of the hopper link 32. A stopper 33 is provided.

In addition, the main body portion has a generally rectangular body 40, the body 40 is formed with a niche (40a) is inserted into the hopper link 32, one side of the niche (40a) In the stepped portion 40b having a relatively low height is formed. Each of the opposite side surfaces of the body 40 is provided with an elliptical groove 40c formed to be inclined upwardly.

In addition, a triangular balance bar 43 is integrally attached to each end edge of the body 40 toward the outer side in the longitudinal direction. A rectangular support plate 45 is vertically attached to the lower end of the body 40. At least two through holes 45a are drilled at a predetermined position of the rectangular support plate 45.

The drive unit of the horizontal table carriage according to the present invention has a rotating roller 50 rotatably mounted in the through groove (45a) formed in the support plate 45 of the lower body 40. The rotary roller 50 has a parallel diameter portion and a shave 52 having a wide end portion, a roller bearing 54 inserted into the center groove of the shave 52, and a roller bearing 54. It consists of a slab 56 inserted into the inner groove. The rotary roller 50 is located on both sides of the support plate 45 in a state in which the support shaft 58 penetrating the through hole 45a of the support plate 45 is inserted.

Therefore, according to the present invention, by inserting the rotary shaft 28 into the groove 26 of the rotary hood in the state that the rotary hood 20 is inserted into the semi-circular groove (30a) of the hopper 30, the rotary hood ( 20 is pivotally mounted to the hopper 30. At this time, the leaf spring 29 is installed on the rotary shaft 28 so that the pivoting operation of the rotatable hood 20 can be smoothly performed.

The hopper 30 to which the rotatable hood 20 is mounted is mounted on the body 40 of the main body. At this time, the hopper link 32 of the hopper 30 is inserted into the niche 40a of the body 40 and the stopper 33 of the hopper 30 is seated on the stepped portion 40b of the body 40. . Hexagon shaft 34 is inserted into the elliptical groove (40c) formed on the opposite side of the body 40 to penetrate the hopper link 32 of the hopper 30, the fixing pins 37 at both ends of the hexagon shaft 34 This is installed to prevent the hopper 30 from being separated from the body 40.

The rotating roller 50 is rotatably mounted in the through groove 45a of the support plate 45 mounted below the body 40. The wire W is bound to the wire coupling member 46 provided on the opposite outer surface of the body 40.

Referring to the operation and effects of the present invention configured as described above are as follows.

3 to 5, when the cut slab S is driven along the roller table to stop on the horizontal table, the port cell detects this and the rod of the cylinder 14 expands to seat the carriage. As the track 12 rises, the carriage is raised to the horizontal table surface.

At this time, when the operator manually operates without confirming the operation state of the track 12, the slab drives and collides with the protrusion 22 of the rotatable hood 20 of the carriage. The ball bearing 24 at the lower end of the rotatable hood slides along the guide groove 30c below the semicircular groove 30a of the hopper 30. That is, in the rotatable hood 20, the protrusion 22 thereof is embedded in the guide groove 30b of the semicircular groove 30a of the hopper 30. At this time, the leaf spring 29 installed on the rotary shaft 28 is wound to receive a resistance. As a result, the impact applied by the slab S cancels out.

On the other hand, when the impact applied through the slab (S) is not canceled by the operation as described above of the rotatable hood 20, in the state in which the rotatable hood 20 is rotated, the hopper of the hopper 30 The hexagonal shaft 34 inserted in the link 32 cancels the impact by sliding along the elliptical groove 40c of the body 40.

Afterwards, when the slab S is driven in the reverse direction, the hopper 30 returns to the niche 40a of the body 40, that is, the hexagonal shaft 34 is positioned below the elliptical groove 40c and the hopper link ( 32 is seated on the niche 40a and the stopper 33 of the hopper 30 is seated on the stepped portion 40b of the body 40 so that the hopper 30 is fixed to the body 40.

Then, the rotary hood 20 inserted into the semicircular groove 30a of the hopper 30 is returned to the initial state by the elasticity of the leaf spring 29 mounted on the rotary shaft 28. That is, the ball bearing 24 returns to the initial position of the guide groove 30c and the elliptical protrusion contacts one side of the hopper 30 so that the rotatable hood 20 maintains the vertical state.

After this, when the rod 12 of the cylinder 14 is contracted and the track 12 is lowered, the carriage is inserted into the space of the horizontal table. When the slab S is driven again and the track 12 is raised, the carriage rises and the slab S is lifted from the horizontal table and transported to the roller table.

If the slab does not recognize the leading slab while driving horizontally, the balance bar of the groove base contacts the track and cancels the load of the slab acting on the carriage so that the carriage does not roll over and derail from the rail of the track.

Therefore, according to the present invention, the casting work due to the slab stagnation of the horizontal table is prevented because the driving of the slab does not confirm that the carriage of the horizontal table is raised, and thus the collision with the raised carriage prevents the equipment from being rolled over and derailed on the track. Stopping and stopping emergency slab transportation It is easy to manage slab information and has a practical effect to prevent safety accidents during carriage recovery.

The foregoing is merely illustrative of the preferred embodiments of the present invention and those skilled in the art to which the present invention pertains may make modifications and changes to the present invention without departing from the spirit and gist of the invention as set forth in the appended claims. It should be recognized.
