Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mounting structure for a wall destruction machine that dismantles a concrete wall such as a building structure.

[0002]

[Prior Art]

 Conventionally, a wall destruction machine for destroying a concrete wall body has a connection plate on a wall destruction arm side and a connection plate on a construction machine side supporting and supporting the same, which are tightly connected by a rotating shaft. In addition, some of the same wall destroyers are mounted vertically movable on the tip of the arm on the construction machine side.

[0003]

[Problems to be solved by the device]

 However, in the conventional example described above, when the pair of wall breaking arms is operated, the wall breaking machine is rotatable in the vertical direction with respect to the arm on the construction machine side. It did not swing in the direction. Therefore, when the wall destruction arm dismantles the concrete wall while holding it, there is a problem that the arm on the construction machine side is pushed and bent due to its reaction and is damaged.

[0004]

[Means for Solving the Problems]

 According to the present invention, a pair of wall breaking arms are pivotally supported by a base frame, and a wall breaking machine that can be opened and closed by a hydraulic cylinder is connected to the tip of an arm on the construction machine side through a connecting portion. In the installation structure of the wall destruction machine, the connection plate to which the same base frame is fixedly connected to the construction machine side connection plate that connects and supports the wall destruction machine by the rotating shaft, and both connection plates are connected. It is intended to provide a mounting structure of a wall destruction machine characterized in that a thick annular rubber body is interposed between the opposing surfaces of.

[0005]

[Action]

 The hydraulic cylinder is extended to operate the pair of wall breaking arms. Then, the concrete wall body is strongly clamped and destroyed, but in this case, the wall destruction arm is displaced laterally or inclined with respect to the construction machine side arm and acts like a swing. However, since a thick annular rubber body is interposed at the connection between the wall destruction arm and the construction machine side, the same thickness annular body cushions the swing operation on the wall destruction arm side. The shock is surely absorbed.

Therefore, even if the pair of wall destruction arms that hold the concrete wall work in a state of being displaced in the left-right direction with respect to the construction machine side arm, the construction machine side arm part may be damaged. There is no such thing.

【Example】

 Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.

A shown in FIG. 1 is a wall destruction machine according to the present invention, which is connected to a front end of an arm 1 of a construction machine B via a connecting portion 2. 3 is a hydraulic cylinder for rotating the breaking machine, 4 is a link mechanism, and 5, 6, 7 and 8 are connecting pins. H is a wall.

As shown in FIG. 2, the wall destruction machine A pivotally supports the base portions 11a and 12a of the pair of wall destruction arms 11 and 12 between the pair of base frames 10 and 10, and also supports both base portions. A hydraulic cylinder 13 for arm operation is laid horizontally just after 11a and 12a, and a cylinder connecting arm 11b is formed at the left and right side ends of the hydraulic cylinder 13 by extending rearward from the bases 11a and 12a of the arms 11 and 12. , 12b tips are interlockingly connected.

Moreover, as shown in FIGS. 4 and 5, the base 11a of the left wall breaking arm 11 has a bifurcated tuning projection 11c toward the base 12a of the right wall breaking arm 12. , 11c are projected and the connecting pin 14 is provided between the tips of the tuning projections 11c, 11c, while the tuning projection 12c is also provided on the base 12a of the wall breaking arm 12 on the right side for tuning. Inserting the connecting pin 14 into the connecting elongated hole 15 provided at the tip of the tuning protruding piece 12c by projecting it between the protruding pieces 11c, and using the connecting pin 14, both tuning protruding pieces 11c, 11c , 12c are connected.

Then, by connecting the tuning projections 11c, 11c, 12c with the connecting pin 14 through the connecting elongated hole 15, the pair of wall breaking arms 11, 12 are symmetrically positioned without being biased. The wall body H is squeezed by holding it in place to destroy it.

Numeral 16 is a tuning protrusion protection plate, which is attached to the front ends of a pair of upper and lower base frames 10 and 10 which cover the tuning protrusions 11c, 11c and 12c from above and below. The protection plate 16 covers the tuning projections 11c, 11c, 12c from the front side as well to prevent wall fragments scattered from the front from colliding.

Reference numeral 17 is a pivot pin that pivotally supports the bases 11a and 12a of the wall breaking arms 11 and 12, and 18 is a connection that connects the cylinder connecting arms 11b and 12b to the arm operating cylinder 13. Pins and 19 are hydraulic pipe connecting parts attached to the arm operating cylinder 13.

Further, a connecting plate 10a is fixed to the rear ends of the base frames 10 and 10, and a rotating shaft 20 is provided at a central portion of the connecting plate 10a so as to project rearward. The connecting portion 2 is rotatably attached to the connecting plate 2a provided on the construction machine B side, and the thickness formed by hard elastic rubber such as synthetic rubber is provided between the facing surfaces 10b, 2b of both connecting plates 10a, 2a. A wide annular rubber body 21 is interposed. Sliding plates 22 and 23 are integrally attached to both side surfaces of the same-width annular rubber body 21, and the same-width annular rubber body 21 is slightly compressed when mounted. It is being worn. Reference numeral 24 is a male screw portion formed on the rotary shaft 20, 25 is a fixing nut screwed to the rotary shaft 20, 26 is a fixing bolt for stopping the loosening of the fixing nut 25, and 27 is a grease injection passage.

The embodiment of the present invention is configured as described above, and the hydraulic cylinder 13 is extended to break the concrete wall H while firmly holding the concrete wall H at the tips of the pair of wall breaking arms 11 and 12. However, in this case, even if the wall destruction arms 11, 12 are displaced from the arm 1 on the construction machine side in the left-right direction or are tilted and act like swinging, the wall destruction arm 11 Since the thick annular rubber body 21 is interposed in the connecting portion 2 between the arms 11 and 12 and the construction machine side, the neck of the wall breaking arms 11 and 12 side is buffered by the same annular rubber body 21. It reliably absorbs the shock caused by the swing operation.

Therefore, according to the above-described embodiment, the pair of wall breaking arms 11 and 12 for holding the concrete wall H are operated in a state of being laterally displaced with respect to the arm 1 on the construction machine side. However, the arm of the construction machine is not damaged.
