Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for remotely connecting a power source and an operating source for a pig iron mixer car from the ground side to the pig iron mixer car side.

As is well known, pig iron mixers are equipped with a furnace body tilting device including an electric motor in order to perform operations such as tapping.

Electric power for energizing the electric motor is provided by connecting a ground-side power supply coupler (power coupler) connected to a ground power source or the like to a ground-side power receiving coupler at the stop position of the pig-mixer car.

However, since the environment at the tap site is extremely poor, it has been strongly desired that the interconnection of the power supply and power receiving couplers be accomplished not manually but by automatic remote control.

Although approaches for this purpose have already been proposed and put into practical use, none of them can be said to be sufficiently superior.

For example, a typical prior art is shown in Japanese Patent Application Laid-Open No. 4726306.

The pig iron mixing car is equipped with a large guide box that opens like a trumpet.
The structure is such that a guide rod is fitted from the side.

The moving frame is moved close to and away from the pig iron mixer car by a cylinder, and the above-mentioned guide rod is supported on this moving frame via a universal joint, and a power supply coupler having a contact surface facing the pig iron mixer car is attached to the moving frame. is provided.

With the guide rod fitted into the guide box, the contact surface of the power supply coupler is pressed by the pressure of the cylinder against the contact surface of the power receiving coupler provided on the mixed rail car and facing laterally, and in this way, Electrical continuity is achieved.

In such prior art, the moving frame, cylinder, guide rod, power supply coupler, etc. must be configured to move as the pig iron mixer moves, resulting in an extremely large structure.

Moreover, since a cylinder is used to bring the contact surfaces of the power feeding coupler and power receiving coupler into contact with each other, the mutual contact pressure of those contact surfaces differs depending on the pressure of the cylinder, and the state of electrical conduction changes, or Furthermore, when the pressure in the cylinder is weak, there is a risk that the contact surfaces will separate.

The purpose of the present invention is to facilitate connection operation by remote control,
Another object of the present invention is to provide an improved connecting device for a power source, etc. for a pig iron mixer vehicle, which can be downsized and can reliably maintain the connected state even after connection.

FIG. 1 is a side view of one embodiment of the present invention, FIG. 2 is a simplified front view seen from the section line ■-■ in FIG. 1, and FIG. Surface line ■aI[Ia, I[1b-
Planes a-ab-b respectively seen from IIIb are shown.

This coupling device basically involves a power feeding coupler 3 being lowered from the ground side by a rope 4 onto a power receiving coupler 2 mounted on a pig iron mixer car 1 at a stopping position for tapping the pig iron mixer 1, etc. As a result, the contact surfaces of both couplers 2 and 3 come into contact with each other, and after this contact, the connected state is maintained by loosening the rope 4 and releasing the suspended state of the power supply coupler 3.

The pig iron mixer car 1 can run on rails 5 with wheels 6, and the power receiving coupler 2 is mounted on the bogie deck 7 as described below.

By connecting the couplers 2 and 3, electric power and operating electric signals for driving the furnace body tilting device of the pig iron mixer car 1 are applied from the ground side.

On the ground side, a swing arm 14 is provided on the support column 10 by an air cylinder 11, and is pivotable in a horizontal plane in the direction of an arrow 13 and in the opposite direction about a shaft 12 having a vertical axis at its base end.

A carriage 15 is provided below from the free end of the swing arm 14.
is suspended by a rope 4 via a rope wheel 16 and raised and lowered by an electric cylinder 17.

The carriage 15 is formed into a rectangular frame, and the power supply coupler 3 whose power supply contact surface is directed downward and horizontally is fixed to the lower part of the carriage 15 .

Upper and lower drum-shaped rollers 18, 1 are provided on both sides of the carriage 15.
9 is pivoted.

A pair of rails 20 that guide the sand rollers 18 and 19 are fixed to the distal end of the swing arm 14 and extend in the vertical direction.

The rollers 18 and 19 and the rail 20 prevent the carriage 15 from shaking when the swing arm 14 swings.

The lower end of the rail 20 has a lead-in portion 21 formed to expand outward.

The use of drum rollers 18, 19 automatically orients and prevents twisting as carriage 15 rises between rails 20.

The lead-in portion 21 of the rail 20 comes out of contact with the drum-shaped roller 18 when the drum-shaped roller 18 is in the lowered position 18a when the couplers 2 and 3 are connected, and regardless of the horizontal displacement of the carriage 15. To surely guide a carriage between rails 20 when rising.

The lower end of the swing arm 14 comes into contact with a locking piece 30 fixed to the pig iron mixer wheel 1 when swinging in the direction of arrow 13, and the swing is stopped at that position.

The power supply coupler 3 is located directly above the power reception coupler 2 when the lower end of the swing arm 14 and the locking piece 30 are in contact with each other.

Guide members 22.2 are provided on the lower side of the carriage 15 on three sides.
3 is fixed.

Each of these guide members 22, 23 has substantially the same structure, and is composed of a plurality of rollers (four in the figure) that are pivoted side by side between a pair of support plates with their axes horizontal.

The two guide members 22 are arranged to face each other, and the remaining guide member 23 is arranged so that its roller axis is orthogonal to the guide member 22.

A weight 24 may be attached to the carriage 15, and the contact pressing force of the power supply coupler 3 onto the power reception coupler 2 may be increased by the weight of the weight.

The cable 25 connected to the power supply coupler 3 is suspended via a guide reel 26 pivotally supported at the lower part of the swing arm 14, thereby preventing damage to the cable 25 from bending and stabilizing the direction of downward feeding of the carriage 15. Become.

The guide members 22 and 23 project vertically below the carriage 15.

A pair of rails 20 are fixed to extend vertically on both sides of the carriage 15, and the drum-shaped rollers 18 and 19 having the aforementioned horizontal axes are attached to the free end of the swing arm 14 so as to be able to come into contact with the rails 20. It's okay.

A pair of bracket bearings 40 are installed on the bogie deck 7 of the pig iron mixer car 1.
．． A box 42 is pivotally supported by the box 41, and its horizontal rotation axis is parallel to the orbital direction of the pig iron mixer wheel 1.

The power receiving coupler 2 is attached to the box 42 with its power receiving contact surface facing upward and horizontally.

Also fixed to the box 42 are guide plates 43 and 44 as other guide members corresponding to the aforementioned guide members 22 and 23, respectively.

In FIG. 3, the guide member 22.23 is replaced by the guide plate 43.44.
It is shown that it is fitted.

The arrangement positions of the guide members 22, 23 and the guide plates 43, 44 in three directions are such that even if the carriage 15 suspended by the rope 4 is twisted around the vertical line,
It serves to correct the twist and accurately position the power supply coupler 3.

The guide plates 43, 44 have the same structure.

As shown in the second diagram, the guide plate 43 is a portion 43 that guides the roller row of the guide member 22 in the vertical direction by sandwiching it from both sides.
The guide member 22 is made up of a guide plate 43 and a lead-in portion 43b which is formed to extend upwardly.

The other guide plates 44 are arranged side by side in pairs, thereby more reliably correcting the twist around the hanging rope 4 of the carriage 15.

A fixing lever 45 is attached to the bracket bearing 4 in the box 42.
They are connected via one pivot pin.

This fixing lever 45 is attached to a support piece 4 provided on the pig iron mixer.
9 from the state shown in the figure with a bolt (not shown) etc.
It can be rotated 0 degrees and fixed.

Therefore, the power receiving contact surface of the power receiving coupler 2 can be changed from a horizontal surface (that is, facing upward) to a vertical surface (that is, facing sideways).

Therefore, it becomes easy to manually connect a separate power feeding bracket (not shown) to the power receiving coupler 2 which is placed sideways.

Next, the connection operation between the power supply coupler 3 and the power reception coupler 2 will be described.

In advance, the swing arm 14 is placed on standby parallel to the track direction of the pig iron mixer as shown in FIG. 3, and the carriage 15 is raised and ready as shown in FIGS. 1 and 2.

Then, the pig iron mixing car 1 is stopped at the tap position.

When connecting both couplers 2゜3, first connect air cylinder 1.
1 to move the pivoting arm 14 in the direction of arrow 13 with the locking piece 3
0 until it locks, resulting in the state shown in the first diagram.

The air cylinder 11 is brought into constant contact with the locking piece 30 by its air spring pressure regardless of the horizontal displacement of the pig iron mixer wheel 1, thereby maintaining the mutually connected position of both couplers 2 and 3.

The air cylinder 11 also serves to absorb the impact caused by contact with the locking piece 30 when the swing arm 14 swings.

Next, the electric cylinder 17 is driven to lower the carriage 15.

After the carriage 15 is lowered along the guide rail 20 and removed from the guide rail 20, the guide members 22 and 23 are drawn into and fitted into the guide plates 43 and 44, respectively, and the carriage is further lowered. .

Therefore, the power feeding contact surface of the power feeding coupler 3 is connected to the power receiving coupler 2.
The device is placed on the power receiving contact surface of the device, and an electrical connection is made.

At this time, the rope 4 is further hung down to the extent that it becomes slack, and the suspension of the carriage 15 is released.

Therefore, the weight of the power supply coupler 3, carriage 15, weight 24, etc. is added to the contact surface of the power reception coupler 2, and the connection between the couplers 2 and 3 is always maintained regardless of the displacement of the pig iron mixer 1 in the horizontal plane or in the vertical direction. ensured that it is maintained.

Since the swing arm 14 can be placed on standby parallel to the pig iron mixer rail 5, this is advantageous from the standpoint of factory layout.

Note that the cable 25 connected to the power supply coupler 3 may be guided along the rope 4.

It can be used instead of the electric cylinder 17 in a winch or the like.

In addition to the rope 4, other flexible cords, such as chains, can be used.

When connecting the power supply coupler 3 and the power reception coupler 2, instead of bringing the two contact surfaces into contact only by their own weight as described above, they may be brought into contact by further applying a pressing force using a spring, a cylinder, or the like.

By selecting the swing arm 14 to be long, displacement of the feed coupler 3 in the horizontal plane in the direction perpendicular to the track direction, which is caused by a slight displacement error in the track direction of the pig iron mixer 1, can be made extremely small.

Instead of the combination of the guide members 22, 23 and the guide plates 43, 44, a combination of a centering guide rod and a large guide cylinder may be used.

As described above, according to the present invention, not only is the connection of the power source and operation source at the stop position of the pig iron mixer car achieved by automatic remote control, but also the horizontal fluctuation of the stop position of the pig iron mixer car and the capacity of hot metal in the furnace can be changed. Even if there is vertical displacement due to fluctuation, the connection can be reliably connected and the connected state can be maintained.

In particular, according to the invention, the lifting means 1 is provided at the free end of the swivel arm.
When the carriage 15 is raised by 7,
The drum-shaped rollers 1B, 19 are guided along the rails 20, thus reliably preventing the carriage 15 from shaking and allowing a safe angular displacement of the swivel arm.

The pivoting arm 14 is pivoted by the air cylinder 11, so that the free end of the pivoting arm 14 is connected to the locking piece 30.
When it comes into contact with the air cylinder, the impact force is buffered by the air cylinder.

When the carriage 15 is lowered, the first guide member 22.
23 and the second guide members 43 and 44 are fitted into each other, whereby the contact surfaces of the power feeding coupler 3 and the power receiving coupler 2 are mutually positioned, and in this state, those contact surfaces are in contact with each other. Since the cables are unsuspended at this time, the contact state of the contact surfaces is reliably maintained even if the pig iron mixer moves.
