The present invention is a device that can safely and easily replace the charge plate on the flat plate by using a crane safely and easily in the air, and automatically adjusts the charge plate position, especially due to the deformation and shrinkage of the charge plate due to the high temperature in the furnace The present invention relates to a charge plate automatic replacement device that can be usefully used to replace a lower charge plate such as an electrical steel sheet annealing plant that needs to be disposed of and replaced.

Generally, when replacing the charge plate 12 to be replaced, the crane is moved to the position of the charge plate 12 to be replaced by using a conventional magnet crane, and the crane is accurately positioned at the center of the charge plate 12 to be replaced on the upper portion of the coil car. The crane is pulled down and replaced by a manual lever.

This charge plate is usually about 1300kg steel plate weight, and the lower part of the coil car is made of weak soft brick, so it can be damaged even by the weak impact of the crane, so the impact should be lowered slowly.

The magnet body, which is slowly lowered, is fixed and fine-adjusted by two sets of workers and then completely lowered to the upper part of the charge plate to be finally replaced, and the charge plate to be replaced by supplying magnet crane power is attached to the magnet body. Then, the crane is lifted by 2 meters and moved to a high place about 30 meters for disposal.

In other words, after attaching the charge plate to be replaced to the crane and moving it to the coil car position, attaching the charge plate to be replaced on the magnet body, it is operated at high altitude and finely adjusted by two-man operation at the top of the coil car. You need to modify the plate position. The problem in replacing the conventional charge plate is that the weight plate must be attached to the lower part of the magnet crane to replace one charge plate and move a considerable distance four or more times at a high altitude. There is a risk of a large safety accident when the crane crashes into another facility.

In addition, because of the manual work of two people in one set of manual work force is a lot of manpower, it is difficult to catch the center due to the fluctuation of the crane, there is a problem that you need to perform the center calibration work many times.

The present invention has been made in order to solve the above-mentioned conventional problems, it was possible to repeat the previous work by hanging a heavy object and moving a considerable distance four or more times with only one movement, the working method of working in one pair It is an object of the present invention to provide a charge plate replacement device that can be safely operated by a single worker alone, a time-consuming work can be performed in a short time, and does not need to be calibrated several times.

Hereinafter, described in detail with reference to the accompanying drawings, the present invention for achieving the above object is as follows.

Figure 1 is a front view of the charge plate replacement device of the present invention, Figure 2 is a plan view from above of the device.

Magnet plate (11) The cylinder tube located in the center of the center, the steel pin bi-directional cylinder (14), the steel pin cylinder rod (15) is provided, and only the plate fixing pin is visible from the outside, and the hydraulic pressure is used to strongly and vertically fixed did.

3 is a detailed perspective view of the plate fixing pin of the hydraulic cylinder, there is a steel pin 16 made of steel on the inside to prevent slipping of the charge plate 10, 12 when rotated 360 degrees. The magnet plate 11 generates an electromagnetic force to strongly hold the charge plates 10 and 12.

4 is a front perspective view of a coil car currently in use. The coil car is composed of a coil car wheel 20, a steel bar 19, and a lead 18 at the bottom thereof, and a charge plate 12 used at the top thereof. .

Figure 5 is a perspective view of the use state of the present invention, with reference to this will be described in more detail the configuration, operation of the present invention.

When the crane is slowly lowered, the center adjustment is automatically performed by the center guide 13, and finally, the center is gradually lowered completely.

In addition, the lower limit (A) attached to the lower portion is also stopped when touched with the soft wire by the center guide 13 also blocks the fine rotation and shaking of the magnet plate 11 and receives a signal from the limit (A) plate steel The pin limit B and the electromagnet on-open limit C are simultaneously crossed to the charge plate 12 to be cross replaced.

The electromagnet on-off limit (C) is generated when the electromagnetic force on and the electromagnetic force is turned off when off the magnet plate 11 serves to hold the charge plate (10) (12) strongly by the force of the electromagnetic force.

Plate steel pin cross limit (B) is the cylinder in position at the cylinder out position (S) to the side of the charge plate (12) to be replaced when the steel pin bidirectional cylinder (14) located in the center portion of the magnet plate (11) moves inward It pulls strongly to (P) to hold the two charge plates (10) and (12), and when the limit (B) (C) is completely crossed, the crane gradually rises at a stable speed and the crane stop limit (D) Will be touched.                     

Then, a signal is given to the motor 1 and the power of the motor is transmitted to the magnet plate 11 body through the coupling 3 and the bevel gear 4 to rotate slowly.

The rotational speed is controlled by the pulse generator 2, which rotates slowly by about 360 degrees in one minute and the rotation is completely stopped by the crane rotation stop limit.

When the rotation stop limit (F) gives the crane lowering signal, the crane lowers the lower part of the coil car and transmits the signal to the plate steel pin limit installed in the charge plate (10) guide to be replaced to simultaneously transmit the magnet plate (11) center center part signal. To open the steel pin and electromagnet operation.

When the electromagnet on limit is open the signal, the electromagnet power is opened and the electromagnetic force is maintained, and after about 10 seconds it is completely extinguished.

The crane is raised to finally work the automatic replacement of the charge plate 10, 12 quickly and safely.

Therefore, the present invention has the effect of allowing the charge plate replacement and position correction of the weight body to be carried out much more easily and safely by the above-described configuration and operation.
