DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a side view of a crusher detachable magnet device showing an embodiment of the present invention. Reference numeral 1 indicates a crusher fixed claw, and 2 indicates a crusher movable claw. 3 is a support shaft of the movable claw 2, 4
Is a fixed side support shaft of the hydraulic cylinder 5, and 6 is a piston side support shaft. Reference numeral 7 shows two holes for attaching to the tip of the arm of the self-propelled machine / construction machine.

The magnet device 10 is fixed to the base 11. The base 11 has a rotating portion 12 on the top thereof.
It is attached so that it can rotate horizontally. Rotating part 12
A partition 13 for inserting the fixed claw 1 is formed on the upper part of the
Moreover, in order to prevent the magnet device 10, the base 11 and the like from coming off due to the pressurization of the movable claw 2, the lateral rod body 14 is laterally fixed to the side surface of the partition portion 13 to form a lateral rod portion. Therefore, as shown in FIG. 1, when the movable claw 2 starts to bite into the fixed claw 1 side, the movable claw 2 naturally bites into the horizontal rod body 14 to generate a strong frictional force, and the magnet device 10 of 1 ton or more is generated.
Also, it will not fall even if the rebar for adsorption is hung. As the material of the horizontal bar body 14, a material that is elastically deformable, such as hard rubber or wood, can be used.

When the movable claw 2 bites into the fixed claw 1 side, a DC power source is energized to the magnet device. That is, as shown in FIG. 2, the positive side electrode 22 is supported by the reinforced oblique plate 21 of the rotating portion 12 by a plurality of springs 23, for example, four. The electrode 22 is insulated by an insulator plate 24. The lead wire 25 is led out from the electrode 22,
The lead wire 25 is electrically connected to the plus side of the electromagnet device 10. On the other hand, on the movable claw 2 side, an electrode plate 26 that is in contact with the electrode 22 is fixed. The electrode plate 26 is also insulated by an insulating bush 27. The lead wire 28 on the movable claw 2 side is connected to the cab power supply device of the construction machine through a connector. The minus side of the power source is connected to the power source device from the magnet device 10 via the fixed claw 1 and the arm of the construction machine. 2 shows a state in which the movable claw 2 is closed, but in a state in which the movable claw 2 is opened, as shown in FIG. 3, the boss 22a of the electrode 22 is projected by a spring. When the movable claw 2 is closed,
As shown in FIG.
a is pressed against the spring 23, and the boss 22a of the electrode 22
And the electrode plate 26 are in a crimped state. Since the electrode plate 26 is set to have an area larger than the boss diameter of the electrode 22,
Even if the support shaft of the movable claw 2 is loosened and their initial positions are displaced from each other, electrical connection is possible. The hole of the movable claw 2 is also formed larger than the boss.

As shown in FIG. 4, the insertion partitioning portion 13 is provided with a reinforcing portion 31 having a triangular cross section so that the fixed claw 1 is not deformed during insertion. The reinforcing portion 31 follows the shape of the fixed claw 1 and is provided at a position where it does not abut. Reference numeral 32 denotes an escape hole when the tip of the movable claw 2 formed in the partition 13 enters. In this case, the presence of the reinforcing portion 31 causes 3
Since it also serves as a guide for inserting the fixed claw 1 of the main claw,
It is possible to insert more smoothly.

As shown in FIG. 2, the rotating portion 12 is horizontally rotatable with respect to the base 11 about a vertical axis. That is, the collar-shaped body 12 a is formed at the lower end of the rotating portion 12, and the collar-shaped body 12 a is engaged with the collar-shaped body 11 a of the base 11. Therefore, when the fixed claw 1 is inserted into the insertion partition portion 13, the fixed claw 1 may come into contact with the inner wall portion of the partition portion 13, but only the insertion partition portion 13 is moved without moving the heavy magnet device 10. The horizontal angle of the partition 13 with respect to the magnet device 10 is corrected by rotation, and eventually,
As shown in FIG. 2, the fixed claw 1 is inserted in a predetermined position.

In the above, the base 11 and the rotating portion 1
2. The relationship between the insertion partition 13 and the magnet device 10
When is lifted from the ground, both horizontal angles are offset from the default position. Therefore, if the position is not returned to the initial setting position, the amount of deviation and deviation described above is accumulated, and the lead wire 25 may be broken.

Therefore, as shown in FIG. 5, a means for restoring the rotation bias is provided between the base 11 and the rotating portion 12. In this example, if the fixed claw 1 repeats with accumulated bias, a pulling force may act on the lead wire 25, which may cause disconnection. Therefore, in order to avoid this, the horizontal rotation unit 12 is rotated to the initial position after rotation. It has an automatic return mechanism. Around the reference position between the base 11 and the rotating portion 12, concentric circular arc slots are formed in the collar body 11a of the base 11, and a plurality of protruding pin bodies 41 are formed in the collar body 12a of the rotating portion 12. The left and right springs 42 are provided between the arcuate groove hole and the pin body so as to restore the rotation part 12 after being biasedly rotated to the left and right with respect to the pin body 41.

Therefore, when the fixed claw 1 is inserted into the insertion partition 13 with the tip thereof displaced, the fixed claw 1 is biasedly contacted with the inner wall of the insertion partition 13, so that the magnet device 10 is provided.
Is fixed, only the upper insertion partition 13 rotates horizontally against the coil-shaped spring 42, and the bias is corrected, but once the magnet device 10 is lifted, the rotation unit 12 moves. On the other hand, the magnet device 10 and the base 11 are returned to the initial position by the elastic return action of the spring 42. Therefore, the biased rotation amount of the insertion partitioning portion 13 is not accumulated, and the risk of cutting the lead wire 25 is eliminated.

In place of the coil-shaped spring 42, a leaf spring
Does not prevent the installation of air cylinders and hydraulic cylinders.

Next, the use of the present invention will be described.
Initially, only the crusher is attached to the tip of the arm of the construction machine and engaged in crushing work at the work site. After the crushing is completed, the fixed claw 1 is inserted into the insertion partition 13 of the magnet device 10 placed on the side of the site, but the operator operates the boom arm at the driver's seat of the construction machine. However, the angle between the fixed claw 1 and the insertion partition 13 often does not match.
In this case, the construction machine itself is moved and corrected, but a slight correction is usually difficult. In this case, since the magnet device 10 and the insertion partition 13 are configured to be horizontally rotatable as described above, when the tip of the fixed claw 1 is inserted into the insertion partition 13 with the tip displaced,
Since the fixed claw 1 is biasedly in contact with the inner wall of the insertion partition portion 13, the magnet device 10 remains fixed and the upper insertion partition 1 is fixed.
Only 3 will rotate horizontally and the bias will be corrected. Then, by gradually inserting the fixing claw 1, correction can be gradually performed, and finally, the fixing claw 1 is completely inserted into the insertion partition portion 13. After that, when the hydraulic actuator 5 of the movable claw 2 is extended and brought into contact with the fixed claw 1 side, the movable claw 2 first bites into the horizontal rod body 14 and then the electrode 2
2, 25 are in contact with each other, and the electrode 22 side is compressed against the spring 23 to be in a completely crimped state. Since the connector on the arm side is electrically connected to the power source, the operator can operate the magnet device 10 by energizing the electromagnet device 10 in the driver's seat.
Can be energized. Therefore, by raising the arm, it can be used in the same manner as a conventional crusher with a magnet device, and its weight is lighter during crushing work than with a crusher with a magnet device, and the crushing work itself can be carried out lightly.

When the operation of adsorbing and transferring the magnetic material such as rebar after crushing concrete is completed by energizing the electromagnet apparatus 10 and the crushing operation is continued again, after moving the magnet apparatus 10 to a safe place, Turn off the power and magnet device 1
0 is placed on the ground, and the hydraulic actuator 5 of the movable claw 2
When is shortened, the contact between the electrodes 22 and 25 is released, and the physically fixed state between the fixed claw 1 and the magnet device 10 is released, so that the magnet device 10 is easily detached from the fixed claw 1. Therefore, the crushing work by the original crusher can be continued.

[0028]

As described above, according to the present invention, firstly, the electromagnet device is separated from the crusher and, if necessary, mounted on the crusher to carry out the adsorption and transfer work of magnetic substances such as reinforcing bars. You can do it.

Secondly, according to the present invention, the operator can easily attach and detach the electromagnet device and the crusher in the driver's seat. At that time, it is possible to automatically turn the power on and off.

According to the present invention, thirdly, the tip of the claw of the crusher can be easily inserted into the insertion partition of the magnet device.

According to the present invention, fourthly, the electrode portion of the plus side lead wire can be prevented from being destroyed when the magnet device is attached or detached, that is, when the movable claw is moved.

Fifth, the present invention can prevent the breakage of the lead wire due to the accumulation of the horizontal rotational deviation when the claws of the crusher are attached.
