Description

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

Generally, when tapping a pig iron mixer car used to transport hot metal from a blast furnace to a steel factory, the pig iron mixer car is pulled by a locomotive, stops at a predetermined position, and then is placed on a truck. It is well known that this can be achieved by operating a tilting device.

In order to supply power to the tilting motor of the tilting device, a dedicated power supply device is installed on the ground near the predetermined stopping position of the pig iron mixer,
A method has been adopted in which the power supply device and the truck-side power receiving device are connected manually.

However, since the working environment at the tap area of the pig iron mixer truck is extremely poor, there is a strong demand for mechanization of the connection operation of the power source and operation source.

Nevertheless, the height of the top surface of the rail of the bogie-side power receiving device changes from time to time due to the hot metal capacity of the pig iron mixer car and the state of wear and tear on the refractories in the furnace, as well as the fact that the running rail may sink or the connection may be fabricated and installed. Due to the presence of errors, the connection position inevitably varies from one pig iron mixer to another, and as a result, it has been considered extremely difficult to put into practical use a device that allows for remote tilting.

The present invention was made in view of these circumstances, and even if there is any variation in the connection position (errors in the vertical, lateral, and horizontal directions) in the connection part on the pig iron car side, the connection surface is always pressed with a predetermined force. , so that they are in close contact with each other, and the iron mixer car automatically grasps the power supply cart from an appropriate distance before the predetermined stopping position of the pig iron mixer car and carries it under one weight to the stopping position of the pig iron mixer car. This system uses a device that allows all operations to be performed remotely.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

In Fig. 1, C is a pig iron mixer, which is equipped with a tilting device T in order to stop at a predetermined position and tilt the furnace body F to tap the iron into the ladle. The power source and operation source for the tilting device are provided by connecting the power receiving device A on the mixer car side and the power feeding truck B on the ground side.

Incidentally, the power feeding truck is mounted via a plurality of wheels on a transition rail R that is especially arranged parallel to the rail of the pig iron mixer car.

FIG. 2 and subsequent drawings are drawings showing the apparatus of the present invention more specifically, and the following description will be made using these drawings.

The power coupler 1 in the power feeding truck B on the ground side is mounted on the upper deck 2 of the power feeding truck via a bracket 1-3.

In addition, if it is necessary to take into consideration the mitigation of impact force when connecting the power couplers 1 and 1', as shown in the figure, the shock absorbing mechanism 4 and the sliding bearing 5 provided on the side of the power coupler 1 and The structure is such that it can be stably held by interposing it between two guide bars 6 fixed to the upper deck 2-A.

Additionally, a centering guide bar 7 with a circular or square cross section is installed on the upper deck 2 to center the power coupler 1 on the power feeder truck B side and the power coupler 1' on the pig iron mixer side. One or two guide bars are fixedly installed, and the tip of the centering guide bar 7 is formed into a conical or pyramidal shape to facilitate centering, and the tip is positioned an appropriate dimension forward of the contact surface of the power coupler 1. By installing the power couplers 1 and 1' in an overhanging manner, it is possible to connect the power couplers 1 and 1' after performing a reliable centering operation.

The upper deck 2 is slidably mounted on two guide bars 9 that are horizontally and parallelly supported by brackets on the floor surface of the power supply cart B by means of a bearing 8 provided on the side surface (bottom surface) of the upper deck. At the same time, it was installed on the floor of power supply truck B.

It has a structure that allows it to move forward and backward by a drive device 10 (an electric cylinder in the embodiment).

In addition, the power supply truck B is mounted on a specially arranged transition rail R in parallel with the rails of the pig iron mixer car via four wheels 11, and is also shown when the power supply connections i51 and 1' are connected. The reaction force in the water direction is supported by a plurality of side rollers 12 provided on the side opposite to the coupler of the power feeding cart by abutting against a guide rail 13 erected along the transition rail R.

Reference numeral 14 denotes a connecting pin that connects the power feeding cart and the pig iron mixer car and allows the feeding cart to move in conjunction with the transfer of the pig iron mixing car. It has a structure that allows it to move forward and backward using an electric cylinder.

On the other hand, the power coupler 1' in the power receiving device A on the pig iron mixer car side is attached to a mounting plate 20 specially equipped on the side of the bogie of the pig iron mixer car.

The mounting plate has a centering guide hole 21 in addition to the power coupler 1'.
In addition to one or two connecting fittings 22, a bracket 25 is attached to a mounting base 24 that has bearings 23 that protrude left and right and is fixed to the side of the bogie of the pig iron mixer truck, as shown in the figure.
Since it is slidably interposed on the guide bar 32 provided through the guide bar 32 and supported between the bearing 23 and the bracket 25 via an elastic support 26 using, for example, a spring, the power supply trolley Even if the center height dimension of the power coupler 1' on the pig iron mixer side varies with respect to the center height dimension of the power coupler 1 on the B side, it is easily absorbed by the mutual expansion and contraction of the elastic supports 26. You will get it.

Further, the connecting fitting 22 is rotatably locked around a pin 27 protruding from the mounting plate 20 at a position suitable for engagement with the connecting pin 14 provided on the power feeding cart B. .

Furthermore, a stopper 2 is placed at a predetermined distance from the connecting fitting.
By fixing 8 to the mounting plate 20, the connecting pin 14
The structure is such that the connecting fitting 22 and the stopper 28 are engaged with each other.

29 is a device for automatically opening the lid of the power coupler 1' attached to the mounting plate 20 prior to the coupling operation;
In this embodiment, it is composed of a combination of a rope and a sheave.

The shape of the centering guide hole 21 is determined according to the shape of the tip of the centering guide bar 7 provided on the power feeding cart B, and is either circular in cross section with a conical lead-in portion or pyramidal. A rectangular cross section with a shaped lead-in portion is used.

Reference numeral 30 is a cable reel that has the functions of feeding power to the power feeding cart B and pulling the power feeding cart B, and one end of the cable is connected to the power feeding cart B, and when there is no need to feed power to the tilting device of the pig iron mixer car. To do this, pull the power supply trolley B with a predetermined force,
At a standby position set at an appropriate distance from the predetermined tilting position of the pig iron mixing car, the wheels 11 of the power feeding cart are moved to the stopper 3.
It is for waiting by making it contact with 1, and it is also possible to have the function of supplying the power source for the drive device on the power feeding trolley B as needed.

Note that the method for making the power feeding cart B stand by at the standby position is as described in l above.
- It is not limited to the Lucreel 30, and there is no problem even if a dedicated drive device is separately installed to perform only the standby position/backward movement.

Next, the operation of the device of the present invention will be explained.

First, as described above, the power feeding truck B is kept in a standby position, and the electric cylinder 15 of the power feeding truck is operated in response to a command of the approach of the pig iron mixer truck to push out the connecting pin 14 in a predetermined manner.

In this state, when the pig iron mixer gets closer and the pig iron mixer side power receiving device A passes in front of the power feeding truck B, the pushed out connecting pin 14 will align the connecting fitting 22 on the mounting plate 20. The connecting pin 14 is rotated upward, and while it is in contact with the stopper 28, the connecting metal fitting is again rotated downward due to the moment due to the deviation of the dynamic center and returns to its original state. engaged between.

Therefore, from now on, as the pig iron mixer car moves, the power feeding truck also moves in the same way, and when the pig iron mixing car stops, the power feeding truck also stops.

Furthermore, in parallel with the operation of connecting the pig iron mixer and the power supply truck using the connecting pin 14, a rope for opening the lid of the power coupler 1' on the pig iron mixing car side is connected to the connecting pin as shown by the solid line in Fig. 5. By changing the state from the state to the state shown by the dotted line, the lid of the power coupler 1' connected to the rope is always kept at least 9
The opening degree is maintained at 0° or more.

Next, when the pig iron mixer is stopped at a predetermined position, the upper deck 2 is advanced by operating the electric cylinder 10 of the power feeding truck B. As mentioned above, the centering U guide bar 7 Since it protrudes from the contact surface of the power coupler 1, the centering guide bar is first drawn into the centering guide hole 21 on the mounting plate 20, and when it is inserted to a predetermined length, the centering is completed. It is done.

This means that the contact surfaces of the power couplers 1゜1' are in contact with each other (
- satisfies the conditions to obtain, as a result of which the electric cylinder 10 can be operated continuously without any hindrance; As mentioned above, the reaction force of
Since the side rollers 12 are supported by coming into contact with the guide rails 13, it is possible to completely suppress the lateral vibration of the power supply cart B, and the connection of the power supply connection gA1.1' is performed by pressing the electric cylinder 10 throughout the power supply period. Since this is done according to the current capacity, extremely reliable power supply work is possible.

Next, a case will be described in which the pig iron mixer side power receiving device A and the power feeding cart B are separated from each other upon completion of the power feeding work.

First, by operating the electric cylinder 10 and retracting the deck 2 partially in the negative direction, the power coupler 1 + 1' is disconnected, and then the centering guide bar 7 moves into the centering kite hole 21.
The separation of the power supply connections 51, 1' is completed after a short distance.

After that, operate the electric cylinder 15 and connect the connecting pin 1.
4, the connection between the power supply truck B and the pig iron mixer side power receiving device A is cut off, and at the same time, the lid of the power coupler 1' is always kept at 90°C.
The rope that had been kept at an opening of more than 30 degrees loses its tension, and the lid automatically falls and closes.

Moreover, the power supply cart B is returned to the standby position by the predetermined tension of the torque reel 30, and is ready for the next power supply operation.

As described in detail above, according to the present invention, bad luck and
This eliminates the need for manual connection of the power source and operating source at the tap area of the pig iron mixer car, which not only makes it possible to operate safely remotely, but also allows The car and the power supply truck are automatically connected, and the weight of the pigeon mixer car and the power supply truck become one until the specified stop position, so the power supply is always connected even if there is any change in the stopping position of the pig iron mixer car. The power supply cart can be positioned within a range that allows for reliable centering for connection of the furnace, and even if there is a change in the capacity of hot metal in the furnace or a change in the state of wear and tear of the refractories in the furnace. There is a great advantage of being able to reliably connect with a certain amount of force.
