The waterproof control panel 5 is provided with a start / stop button so that it can be operated simply and controls the rotation of the take-up reel 2 finally.

The AC electric motor 6 is a power source having a capacity of 3HP and is installed at the lower end of the reducer 8 to reduce the overall size, and an outdoor type is applied.

The chain / sprocket 7 transmits the power between the electric motor 6 and the speed reducer 8 and at the same time decelerates the rotational speed of the electric motor 6 by one degree.

The 4-speed reduction gear 8 of the foot mounting type is compact as a concentric gear reducer whose input shaft and output shaft are in a straight line in which the number of revolutions of the motor 6 is finally decelerated, To take charge.

The coupling 9 is a clutch applied to transmit the power between the speed reducer 8 and the take-up reel 2.

The shaft 10 is adapted to receive the power from the coupling 9 and transmit it to the take-up reel 2 to support the weight of the take-up reel 2. A reel crank arm 11 is provided on the left side of the shaft 10, and a feeder thread is machined on the right side.

The reel crank arm 11 finally transmits power to the take-up reel 2 (power is transmitted by pinning the take-up reel and reel crank arm), and the reel crank arm 11 stops on the shaft 10 Up reel (2) with different pin hole positions for the reel flange by applying a slot hole to the crank arm so that the reel flange can be easily fixed to the take-up reel (2) A conical sleeve is attached to the boss portion so that the reel having boss inner diameters of various sizes can be mounted without difficulty.

The reel clamp 12 is assembled with the male thread of the shaft 10 and is movable in the axial direction and fixes the take-up reel 2 so as not to move in the axial direction.

That is, since the reel clamp 12 can be transported in the axial direction and the conical sleeve is applied to the reel contact portion, when the width of the reel is different or the boss diameter of the reel differs according to each work, So that the reel can be easily fixed.

The take-up reel (2) is made of wood and is supplied together with wire rope producers to supply wire rope. It uses an empty reel and has different diameters and widths for crane specifications and wire rope producers. The function is to hoist the old wire rope of the crane to be replaced, so that the take-up reel (2) is ready to be replaced with no wire rope.

The feeder reel (3) feeds the new wire rope to the crane. When the wire rope is replaced, the feeder reel (3) is connected to the end of the rope and supplies the new wire rope to the crane by the torque of the take-

The method of installing the feeder reel (3) is the same as that of the take-up reel (2), and the feeder reel (3) with the wire rope ready to be replaced is newly wound.

The band brake 13 is provided at the shaft end of the feeder reel 3. When the handle is turned clockwise, the tension of the band is increased to increase the braking force. When the band brake 13 is turned counterclockwise, Can be controlled.

The band brake 13 is detachable so that the feeder reel 3 and the shaft 10 can be separated from each other. When the pin of the band brake 13 is pulled out, it is separated from the left and right. .

The bearing stand 14 is separable from the upper and lower parts. When the upper part of the bearing stand 14 is separated, the take-up reel 2 or the reel 3 is very easy to remove or mount and supports the weight of the reel through the shaft 10 .

The function and effect of the present invention will be described below.

In order to more easily understand the operation procedure and the method of use of the present invention, a description will be made of an example of a hoisting-jacket replacement procedure of a container crane as follows.

The present invention is positioned on the ground below the wire rope drum 18 of the machine room 16 and the head block, which is a hoisting machine, is placed on the ground surface and the rope loosened, Disconnect the wire clamp near the jactuator (15) on the water side.

After the wire clamp is disassembled, the rope clamps A and A 'are separated from the drum 18 by fixing the rope at a wire rope outlet 17 of the machine room 16 using a chain lever.

A messenger rope is connected to the end of the rope separated from the drum 18 in a defined manner and then connected through a hole and a small sheave guide installed at the bottom of the machine room 16, Send each down.

The connecting rope descending from A is connected to the take-up reel (2) and fixed, and the connecting rope descending from A 'is connected to the end of the new rope mounted on the feeder reel (3) Remove the chain lever fixing the power and connect the power.

When the start button provided on the control panel 5 is pressed, the electric motor 6 is started and finally the power is transmitted to the take-up reel 2 to rotate at a speed suitable for wire rope replacement. (Power transmission sequence: motor 6 → chain / sprocket 7 → decelerator 8 → coupling 9 → shaft 10 → reel crank arm 11 → take-up reel 12) When the uplift 2 is rotated, the old rope is wound on the take-up reel 2 through the connecting rope and the new rope mounted on the feeder reel 3 is routed through the connecting rope to the end of the rope Up reel 2 is connected to the one-point A 'point, so that the same speed roll new rope as that of the take-up reel 2 is supplied by the rotational force of the take-

As a result, the new rope is connected to the end of the rope so as to form a route of a predetermined wire rope (A 'point → girder end sheave 19 → Troiley sheave 20 → head block A head block sheave 21 → a trolley sheave 20 '→ a boom end sheave 22 → a trolley sheave 20 → a head block sheave 21' → a trolley sheave 20 '→ The wire rope is automatically changed along the girder end sheave (19 '), the opposite drum (point A), and the connection point between the connecting rope and the new rope reaches point A.

When the new fife reaches the point A, the stop button on the control panel 5 is depressed to stop the rotation of the take-up reel 2 and use the chain lever at the rope exit 17 of the machine room 16 to move the new rope After fixing, final adjust the length of the rope (in front of connection point A and connection point A ') and replace the wire rope by fastening each end of the new rope to the drum.

Thus, the present invention is independent of the crane and can move easily, so that it can be used as a target of several cranes. Therefore, it is very economical and it is possible to replace the rope on the ground, There are many effects such as.
