It is.

FIG. 1 is a plan view of an embodiment of the present invention, and FIG. 2 is a side view thereof.

The power source and operation source for the furnace body tilting device (not shown) of the pig iron mixing car 1 are provided by a power receiving coupler 3 included in the power receiving device 2.
This is done by connecting the power supply coupler 5 of the power supply device 4 provided on the ground at the tapping stop position of the pig iron mixer car 1.

The pig iron mixer car 1 is mounted on rails 6 via wheels 7.

Referring to FIG. 3, the front side of the power receiving device 2 is shown.

A pair of upper and lower bracket bearings 11.12 fixed to the bogie deck of the pig iron mixer 1 support the rectangular outer frame 15 so as to be rotatable about a vertical axis by means of pins 13.14.

A rectangular inner frame 16 surrounded by an outer frame 15 has pins 17
．． 18, it is pivotally supported on the outer frame 15 so as to be rotatable about a horizontal axis parallel to the track direction of the pig mixer wheel 1.

A power receiving coupler 3 is mounted within the inner frame 16 with its power receiving contact surface 3a facing vertically toward the outside of the pig iron mixer car 1.

Therefore, the pins 13, 14; 17, 18, the outer frame 15, and the inner frame 16 work as a universal joint for supporting the power receiving coupler 3 on the pig iron mixer car 1.

FIG. 4 is a sectional view of centering guide large cylinders 19, 20, and 21 arranged horizontally and parallel to each other on the inner frame 16.

Corresponding to these large guide cylinders 19, 20, 21, centering guide rods 31, 32.3 are provided on the movable frame 30 of the power supply device 4.
3 is installed protrudingly.

Inside the moving frame 30, the power supply coupler 5 has its power supply contact surface 5a.
It is mounted so that it is vertical and facing the direction of the pig iron mixer car 1.

Guide holes 19, 20, 21 and guide rods 31, 32° 33
This is to achieve accurate centering of both couplers 3 and 5.

The guide rod 31 etc. has a circular cross section, for example, and its tip is formed into a conical shape to facilitate centering.

The large guide cylinder 19 has, for example, a conical lead-in portion 19a at its tip, and is formed to have a circular cross section to fit the corresponding guide rod.

Referring again to FIGS. 1 and 2, power supply device 4 is attached to a pedestal 34 fixed on the ground.

The support column 35 extends in the vertical direction and is fixed to the frame 34, and supports the vertical member 36 by means of a pin 37 so as to be rotatable about a vertical axis.

The vertical members 36 together with the horizontal members 38 and the diagonals 39 form a triangular frame.

The rotating air cylinder 40 rotates this frame, which is pivotally supported by the pin 37, in the direction of the arrow 50 and in the opposite direction, so that the support frame 41 can wait at the position shown by the two-dot chain line 41a. can.

The support frame 41 supports the movable frame 30 movably along the longitudinal direction of the support frame 41 by means of a moving air cylinder 42 .

An end of the support frame 41 is supported by the vertical member 36 by a bearing device 43, which will be described later.

A vertically tilting air cylinder 44 is interposed between the support frame 41 and the horizontal member 38, so that the support frame 41 can tilt vertically about the horizontal pin 45 of the bearing device 43.

FIG. 5 shows a side view of the bearing device 43 shown in FIG. 2, and FIG. 6 shows a cross section taken along the line VI-Vll in FIG.

In this bearing device 43, a shaft 4 is attached to the end of the support frame 41.
6 is fixed, and this shaft 46 extends horizontally along the longitudinal direction of the support frame 41 and is loosely inserted into a through hole of a block body 47 that serves as a bearing.

The support frame 41 can therefore be pivoted about its longitudinal axis.

This block body 47 has a pair of horizontal pins 45 as shown in the figure.
is pivotally supported on the vertical member 36 by.

In this way, the support frame 41 and therefore the power supply coupler 5,
It is supported by the support column 35 via a universal joint including pins 37 and 45.

At the tip of the support frame 41, rollers 51, 52, 53 having rotating shafts parallel to the longitudinal direction thereof are supported.

The rollers 51 , 52 , 53 can come into contact with the vertical outer surface of the inner frame 16 by passing through guides 54 protruding from the vertical outer surface of the inner frame 16 .

A pair of stoppers 60 are provided on the outer side of the inner frame 16 to limit downward displacement of the support frame 41.

In the connection operation between the power receiving coupler 3 and the power feeding coupler 5, the moving air cylinder 42 moves the moving frame 30 backward to the right as shown in FIGS. The support frame 41 is kept on standby as indicated by 41a.

Further, the support frame 41 is pushed upward to a predetermined position by an air cylinder 44 for vertical tilting.

In such a preparation state, when the pig iron mixer 1 stops at the taping position, (1) first, the support frame 41 at the position indicated by the two-dot chain line 41a is moved by the arrow 50 using the swinging air cylinder 40;
The rollers 51, 52, 53 are rotated in the direction of the guide 5.
4 and the outer side surface of the inner frame 16.

(2) Next, operate the vertical tilting cylinder 44 to
The support frame 41 is pushed upward using 5 as a fulcrum.
is lowered in the direction of arrow 48 until it abuts stopper 60 and held at that position.

At this time, the three rollers 51 to 53 roll downward while being pressed against the outer surface of the inner frame 16 by the air pressure of the cylinder 40.

Therefore, the support frame 41 has an axis 46 extending in its longitudinal direction.
Rotates along the outer surface of the inner frame 16 around .
This eliminates mutual angular deviation or twist about the normal line of the contact surfaces of both couplers 3, 5.

The outer surface of the inner frame 16 and the rollers 51, 53 or 52,
53 prevents rotation of the receiving coupler 3 about the vertical axis including the pin 13.14.

The contact between the lower end of the tip of the support frame 41 and the stopper 60 prevents the power receiving coupler 3 from rotating around the horizontal axis including the pins 17 and 18.

The outer surface of the inner frame 16 and the roller 51.52 or 51.5
3, the support frame 41 around the axis of the shaft 46
rotation or twisting is prevented.

(3) After that, the moving air cylinder 42 moves the frame 3
0 to the left, and centering is performed by fitting the guide rods 31, 32, 33 into the large guide cylinders 19, 20° 21,
The contact surfaces of both couplers 3 and 5 are elastically pressed by the air pressure of the moving air cylinder 42.

In this way, communication between the couplers 3 and 5 is established.

Even if the pig iron mixer 1 is displaced or fluctuated in the horizontal track direction and the vertical direction during and after the couplers 3 and 5 are connected, the pins 13, 14; 17, 1B in the power receiving device 2
pin 37 in the universal joint and power supply device 4;
5, the couplers 3 and 5 are constantly pressed together by the air pressure of the moving air cylinder 42, and the piston rod of the moving cylinder 42 is movable, that is, telescopic, so that the coupling state cannot be released. There is no risk of being forced to do so.

For example, if the pig iron mixer 1 is displaced in the track direction within a horizontal plane,
The displacement is absorbed by the action of pins 13, 14 and pin 37.

Moreover, if the pig iron mixer 1 moves in the vertical direction, the pins 17, 1
8 and pin 45, the fluctuation is absorbed.

Note that the use of the air cylinders 40, 42, and 44 is advantageous in that they also have the function of absorbing shocks using their air pressure.

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, it is possible to reliably communicate and maintain the connected state.

In particular, according to the present invention, the power supply coupler 5 and the power reception coupler 3
and are brought into contact with each other's torsion corrected, so
Accurate connection status is achieved.
