The work machine main body 1 includes a traveling body 4, a revolving body 6 installed on the traveling body 4 via a revolving device 5, a hydraulic power unit 7 and a cab 8 mounted on the revolving body 6. Reference numeral 9 denotes an exterior generator with an engine mounted on a building 10 that covers the hydraulic power unit 7 and the like via a mounting device 11, and supplies power to the lifting magnet 3. The generator 9 may supply power to other devices that require power.
  The working arm 2 includes a first arm 13 attached to the swing body 6 by a hydraulic cylinder 12 so as to be raised and lowered, and a second arm 15 attached to the tip of the first arm 13 so as to be rotatable by a hydraulic cylinder 14. It consists of.
  The lifting magnet 3 has an electromagnet and is suspended from the second arm 15 via a pin 16. The lifting magnet 3 may be attached so as to be able to swing by a hydraulic cylinder attached to the second arm 15. The lifting magnet 3 attracts an iron object by energizing the coil through a switch from the generator 9 and releases the object by stopping the energization to load, unload, and collect the work. Is to do.
  FIG. 2 is a plan view showing an embodiment of a base frame 20 constituting the generator mounting device 11 according to the present invention, and FIG. 3 is an enlarged cross-sectional view taken along line EE of FIG. In these drawings, 20 is a base frame fixed on the building 10 on the revolving structure 6 of the work machine main body 1, and 9 is the engine-equipped exterior generator. A frame-like attachment portion 22 is provided on the lower surface of the generator 9. Reference numeral 24 denotes an anti-vibration rubber provided between the base frame 20 and the mounting portion 22. Reference numeral 25 denotes a bracket for preventing the generator 9 from dropping when the vibration isolating rubber 24 is damaged. These attachment and combination structures will be described below.
  The base frame 20 is formed by welding a rectangular generator mounting plate 28 on a frame body formed into a rectangular shape by vertical and horizontal frame members 26 and 27 made of beams. The base frame 20 is fastened by screwing a nut 32 to a bolt insertion hole 29 provided in at least one of the vertical and horizontal frame members 26 and 27 and a bolt 31 inserted into the bolt insertion hole 30 provided in the building 10. By doing so, it is fixed on the building 10.
  The anti-vibration rubber 24 is provided in plural (four in the present embodiment) on the generator mounting plate 28. As shown in the perspective view of FIG. 4A, these anti-vibration rubbers 24 are formed by fixing a lower plate 34 and an upper plate 35 made of metal plates to the upper and lower surfaces of a columnar rubber 33. The lower plate 34 has a flange portion 34a projecting on both sides of the rubber 33 and a bolt insertion hole 34b provided in the flange portion 34a for attachment to the base frame 20.
  As shown in FIG. 4 (B), the bolt 36 is inserted into the bolt insertion hole 34b and the bolt insertion hole 28b provided in the generator mounting plate 28, and the bolt 36 is screwed into the nut 37 to thereby prevent vibration. The rubber 24 is fixed on the generator mounting plate 28 of the base frame 20. Further, the anti-vibration rubber 24 is provided with an upward bolt 39 embedded in the rubber 33 and integrated with the upper plate 35 for attachment to the attachment portion 22.
  5A and 5B are a plan view and a side view showing the structure of the bracket 25, respectively, and are views taken in the direction of the arrow F in FIGS. The bracket 25 of this embodiment is manufactured by punching and bending a flat metal plate. The bracket 25 has a horizontal plate portion 25a and a vertical plate portion 25b, and the horizontal plate portion 25a has a bolt insertion hole 25c through which the bolt 39 is inserted.
  As shown in the plan views of FIGS. 3 and 6, the generator mounting plate 28 has a groove 28 a into which the bracket 25 is inserted. Here, as shown in FIG. 6, the length a of the groove 28a is longer than the width b of the vertical plate portion 25b so as not to limit vibration due to the operation of the generator 9 or vibration during traveling of the work machine. The width c is set larger than the thickness d of the vertical plate portion 25b, and the vertical plate portion 25b is loosely fitted in the groove 26a. On the other hand, the lower end portion of the vertical plate portion 25b has a retaining protrusion 25d projecting on both sides in order to prevent the bracket 25 from slipping out of the groove 28a. The width e between the tips of the protrusions 25d on both sides is set larger than the length a of the groove 28a.
  In the bracket 25, the horizontal plate portion 25a is inserted from below the groove 28a, and the bolt insertion hole 25c is fitted to the bolt 39 as shown in FIG. And the bolt insertion hole 22a provided in the attachment part 22 of the said generator 9 is fitted on the bolt 39 on it, the nut 40 is screwed and fastened to the bolt 39, and the generator 9 is passed through the vibration isolating rubber 24. It is fixed on the base frame 20.
  In the state where the generator 9 is mounted on the building 10 in this way, the vibration accompanying the operation of the generator 9 is absorbed by the vibration isolating rubber when the generator 9 is previously provided with the vibration isolating rubber. In addition, it is absorbed by the anti-vibration rubber 24. For this reason, the vibration of the generator 9 is prevented from being transmitted to the building 10. In addition, vibration generated when the work machine travels on an uneven surface is absorbed by the vibration isolating rubber 24, and vibration transmission to the generator 9 is absorbed, and the generator 9 is provided with the vibration isolating rubber 24 in advance. In such a case, the anti-vibration rubber 24 is also absorbed. Here, since the vibration-proof rubber 24 provided according to the present invention can select a suitable size and type to absorb large vibrations generated by running of the work machine, vibrations applied to the generator 9 are greatly suppressed. Therefore, the generator 9 is prevented from being damaged by the vibration generated by the traveling of the working machine.
  Further, when the rubber 33 of the anti-vibration rubber 24 is cut off due to vibration during traveling or the rubber 33 and the lower plate 34 or the upper plate 35 are separated, the horizontal plate portion 25a of the bracket 25 is attached to the mounting portion by the bolt 39. 22, the vertical plate portion 25 b is prevented from coming off from the groove 28 a by the projection 25 d while being fitted in the groove 28 a, so that the generator 9 is prevented from coming off from the base frame 20 by the bracket 25. The generator 9 is prevented from falling from the building 10.
  Further, in the present embodiment, the horizontal plate portion 25a, which is one end side of the bracket 25, is fixed to the mounting portion 22, and the vertical plate portion 25b, which is the other end side, is prevented from being restricted in vibration of the vibration isolating rubber 24. Since the vertical plate portion 25b is loosely fitted in the groove 28a, the function of the anti-vibration rubber 24 is not impaired, and the transmission of vibration between the building 10 and the generator 9 is well prevented.
  Further, in the present embodiment, the fall-preventing bracket 25 is formed by bending a plate material, and the bolt insertion hole 25c of the horizontal plate portion 25a of the bracket 25 is used for fixing the vibration isolating rubber 24 to the mounting portion 22 Since the vertical plate portion 25b is loosely fitted in the groove 28a of the generator mounting plate 28 of the base frame 20 and is prevented from coming off by the projection 25d, it is attached without using a bolt dedicated to the bracket. Therefore, the structure can be simplified, the mounting can be facilitated, and the number of parts can be reduced.
  In the above-described embodiment, the base frame 20 is mounted on the building 10. The base frame 20 is a generator-mounted frame or counterweight specially provided on the revolving structure 6 constituting the work machine body 1. It can also be mounted on top.
