Definitions

  • the present invention relates to a wheeled crane capable of performing operation for versatile uses, and particularly to a crawler crane.
  • the crawler crane one kind of wheeled cranes, is excellent in stability and has a good traveling performance in uneven grounds and weak grounds, and operating uses thereof are various.
  • an operating attachment for example, such as a 3-point type, a folding leader, a standard crane and the like.
  • FIG. 9 shows an example of the 3-point type in which a leader attachment 52 for controlling a driving direction so that a pile may be driven accurately at a given angle is incorporated into a crawler crane 51 having a winch for hoisting a pile or a pile driver.
  • the lower part of a leader 54 provided with a front outrigger 53 is connected to a base machine 55 which is a crane body, and the upper part of the leader 54 is supported by two stays 56 connected to left and right at the rear of the base machine.
  • the base machine 55 is provided with a rear outrigger 57 for supporting the stays 56.
  • a hydraulic source for operating a leader is provided, and the leader 54 can be adjusted in angle of inclination in all directions. In a two-face type leader which can be also rotated, switching between excavation and driving can be done simply.
  • FIG. 10 shows an example in which a folding leader is incorporated.
  • the lower part of a leader 58 is connected at two upper and lower parts in a base machine 55 and a front portion of the base machine.
  • FIG. 11 shows an example in which a standard crane is incorporated.
  • the lower part of a boom 59 is mounted on the base machine to be rocked freely back and forth.
  • the wheeled crane according to the present invention comprises a revolving frame, a front end of the revolving frame, and an engaging portion provided at the upper part of the revolving frame in the vicinity of the front end, the engaging portion enabling an operating attachment replaceable engagement.
  • the operating attachment can be engaged replaceable, various operating attachments can be incorporated in the crane body. As a result, this can correspond to versatile-use purposes.
  • the engaging portion of the revolving frame is utilized along with the engaging portion of the front end of the revolving frame (in this case, an adapter is preferably used), a large span between the support portions of the operating attachment is taken. Therefore, there is no possibility that the vertical dimension of the revolving frame increases as in the conventional exclusive-use machine, and the revolving frame can be miniaturized, and the cost can be reduced thereby.
  • the wheeled crane according to the present invention further comprises a revolving frame, and an engaging portion provided in the rear end of the revolving frame, the engaging portion enabling an operating outrigger detachably engagement.
  • the operating outrigger can be detachably engaged, the operating outrigger can be easily incorporated in the crane body only when necessary. As a result, this can correspond to versatile-use purposes.
  • FIGS. 1 and 2 are respectively a top view and a side view showing the detailed construction of a revolving frame of a crawler crane which is one kind of wheeled cranes according to the present embodiment (hereinafter merely referred to as "a crawler crane”); and FIGS. 3 and 4 are respectively a top view and a side view showing the whole constitution of the crawler crane.
  • the present crawler crane is similar to that of prior art in that an operating attachment 3 can be mounted forwardly of a revolving frame 2.
  • the present crawler crane 1 is different from the prior art in that as shown in FIGS.
  • the front end of the revolving frame 2, and the rear portion of the front end and the upper portion of the revolving frame 2 are provided with pin holes (corresponding to engaging portions) 4, 5, 6, 7, respectively, engageable freely replacing the operating attachment 3.
  • the present crawler crane is also different from the prior art in that pin holes (corresponding to the engaging portions) 9, 10 engageable detachably mounting an operating outrigger 8 are provided at the rear end of the revolving frame 2.
  • pin holes (corresponding to the engaging portions) 9, 10 engageable detachably mounting an operating outrigger 8 are provided at the rear end of the revolving frame 2.
  • FIG. 5 shows an example in which a 3-point type operating attachment is incorporated.
  • a rigid revolving frame 2 is mounted to be revolved freely on a traveling body 12 provided with traveling crawlers 11 on both sides.
  • the lower part of a 3-point type leader 13 which is one example of an operating attachment 3 is connected to the front end of the revolving frame 2.
  • a main winding drum 14, an auxiliary winding drum 15, and a boom rising and falling drum 16 are arranged in a row on the frame at the rear thereof so as to wind each operating rope.
  • the revolving frame 2 is in the construction of a box with left and right side longitudinal plates 2a as bases, as shown in FIGS. 1 and 2, to thereby provide a sufficient rigidity.
  • the left and right side longitudinal plates 2a are formed in the front ends with upper an lower pin holes 4, 5, and stays 17 extended from the leader 13 are connected by means of the pin holes 5.
  • the rear portion of the left and right side longitudinal plates 2a and the upper portion of the left and right side longitudinal plates 2a are formed with pin holes 6, 7 side by side, and stays 18 branched from the stays 17 are mounted in the pin holes 6, 7 through an adapter 19.
  • the adapter 19 is for example, in the form of a triangular plate, lower end of which is engaged in the pin holes 6, 7, and upper end of which is engaged with the stays 18.
  • the distance between the engaging portions with the revolving frame 2 of the stays 17, 18 can be taken as long as possible, and even if the span between the pin holes 4, 5 in the front end of the revolving frame 2 is not long, the sufficient supporting force can be obtained. Conversely speaking, the span between the pin holes 4, 5 in the front end of the revolving frame 2 can be suppressed to miniaturize the revolving frame 2. Note that the adapter 19 is used only when the pin holes 6, 7 are used.
  • FIGS. 6A to 6C While the falling preventing counterweight 20 is originally mounted in a 3-layer construction on the rear portion of the boom rising and falling drum 16, that is, the rear end of the revolving frame 2, an outrigger mounting member 21 as shown in FIGS. 6A to 6C is provided.
  • FIG. 6A is a top view
  • FIG. 6B is a rear view
  • FIG. 6C is a sectional view taken along line I-I.
  • Two stays 14 extended from the upper portion of the leader 13 are connected to the upper surface of the outrigger mounting member 21, and the leader 13 is supported vertically by the stays 14.
  • Operating outriggers 8 are expansively mounted on left and right projecting portions of the outrigger mounting member 21 in order to support the stays 14.
  • two pin holes 9, 10 are provided at upper and lower portions at the rear end of the left and right side longitudinal plates 2a so as to connect the operating outriggers 8 thereto.
  • a bracket portion 21a of the outrigger mounting member 21 is fitted into the rear end of the left and right side longitudinal plates 21, and the pin holes 9, 10 are engaged with the bracket portion 21a.
  • the operating outriggers 8 are mounted on the ends on both sides of the outrigger mounting member 21, and the stays 14 are mounted upwardly on both sides of the outrigger mounting member 21.
  • a counterweight 20 is mounted upwardly of the outrigger mounting member 21. In this case, however, the outrigger mounting member 21 is filled with hunting such as iron scraps in order to supply the shortage of weight of the counterweight caused by the outrigger mounting member 21.
  • an engine not shown is arranged on the frame projected to left forwardly of the revolving frame 2 in FIGS. 3 and 4, and a power plant comprised of a hydraulic pump or the like likewise not shown is driven by the engine to supply pressure oil to the drums, the revolving device and the like, and to supply the traveling driving force also.
  • a cabin 22 is provided on the frame projected to right forwardly of the revolving frame 2, where an operator performs various operations.
  • the present crawler crane 1 is able to easily correspond to the 3-point type operating attachment.
  • the 3-point type operating attachment is replaced by, for example, the folding type one.
  • the lower part of the leader 22 is supported by the front outrigger 22a, as shown in FIGS. 1, 2 and 7.
