Description

The present invention relates to an attachment for demolition equipment used in demolition of structures.

Conventionally, demolition work of structures such as apartments and high-rise buildings is performed using demolition equipment such as heavy machinery. The demolition work differs depending on the type of structure and the work place, and in such cases, different demolition work is often performed by exchanging the attachment attached to the arm of the demolition device. However, the dismantling work is interrupted because it takes a certain amount of time to replace the attachments. Also, the number of dismantling devices may be limited in the work area for the dismantling work, and in such a case, the dismantling work itself may not be possible.

In addition, since structures are composed of various materials, it is difficult to sort the pulverized materials after dismantling the structures, and they are often collected and disposed of as mixed waste. If the main structure is made of reinforced concrete, after demolition, the concrete and reinforcing bars must be separated and disposed of as industrial waste. For example, a dismantling device has been proposed for separately dismantling the concrete and reinforcing bars of a tower-like building (for example, Patent Document 1), but it requires a dismantling device having a plurality of arms, and it can be used depending on the work place. is sometimes difficult. Therefore, depending on the site space and construction period, reinforced concrete may be sent to a processing facility for separate processing, but the underwriting unit price will be high. On the other hand, the heat insulating material (for example, urethane foam) included in the outer wall is generally handled manually.

As described above, in the present embodiment, including the modified examples, the attachment is provided with a plurality of structure demolition units, and there is no need to replace the attachment. Therefore, the work time required for replacing the attachment can be reduced. In particular, by providing attachments with structure demolition units having different functions, a single demolition apparatus can perform different demolition operations without exchanging attachments. Therefore, it is possible to provide various dismantling methods in the demolition of structures.

<Second embodiment>
One embodiment of the invention is an attachment for a demolition device that includes a first structure demolition unit and a second structure demolition unit. In contrast to the configuration in which one rotation control device is provided in the first embodiment, the configuration in which two rotation control devices are provided in the present embodiment.

The dismantling device 2 and the attachment 42 will be described with reference to FIG. . In addition, in this embodiment, description of the same configuration as in the first embodiment is omitted.

The second rotating shaft 530 may be part of the arm 30 or part of the attachment 42 .

The attachment 42 includes a first structure demolition unit 400 and a second structure demolition unit 410 . The first structure demolition unit 400 and the second structure demolition unit 410 are connected to the first rotation control device 500A. The first rotation control device 500A also has a mechanism for rotating the first rotation shaft 510 of the first structure dismantling unit 400 . That is, the first structure dismantling unit 400 of the attachment 42 rotates about the first rotation shaft 510 as a central axis. In the first embodiment, the rotation control device 500 rotates the first rotation shaft 510 of the first structure dismantling unit 400 and the rotation control device 500 itself is a mechanism for rotating the fixed shaft 31 . On the other hand, in this embodiment, the first rotation control device 500A rotates the first rotation shaft 510 of the first structure demolition unit 400, and the second rotation control device 500B rotates the second rotation shaft of the arm 30. 530 is a mechanism for rotating. That is, each rotation control device rotates only one rotation shaft.

In this embodiment, one rotation control device is a mechanism for rotating only one rotation shaft, so the mechanism of the rotation control device can be simplified. Therefore, the number of components of the rotation control device can be reduced, and the size can be reduced. Also, the cost of the attachment can be suppressed.

<Third Embodiment>
One embodiment of the invention is an attachment for a demolition device that includes a first structure demolition unit and a second structure demolition unit. In the first embodiment and the second embodiment, the first structure dismantling unit or the second structure dismantling unit has a rotation shaft, and the first structure dismantling unit or the second structure dismantling unit is rotated by the rotation control device provided in the attachment. While the second structure dismantling unit rotates, in the present embodiment, the first structure dismantling unit and the second structure dismantling unit do not have a rotating shaft.

The dismantling device 3 and the attachment 43 will be described with reference to FIGS. 6 and 7. FIG. In addition, in this embodiment, the description of the configuration similar to that of the first embodiment or the second embodiment is omitted.

FIG. 6A shows the dismantling device 3. FIG. The arm of the dismantling device 3 is divided into an arm 30A and an arm 30B, and the arm 30A and the arm 30B are connected via a second rotating shaft 540. As shown in FIG. The arm 30B rotates around the second rotation shaft 540 as a central axis. Although not shown, a control device for rotating the second rotating shaft 540 may be provided inside the arm 30A, or may be provided inside the upper rotating portion 10 of the dismantling device 3. . FIG. 6B shows a state in which the arm 30B is rotated by 90° with the second rotation shaft 540 as the central axis. An attachment 43 is provided at one end of the arm 30B.

The first structure demolition unit 400B and the second structure demolition unit 410 are connected to the rotation control device 500C. Further, the rotation control device 500C rotates around the fixed shaft 31 as a central axis. That is, the attachment 43 rotates about the fixed shaft 31 as a central axis. However, unlike the first structure demolition unit 400 of the first embodiment, the first structure demolition unit 400B does not have the second pivot shaft 520. As shown in FIG. Therefore, the rotation control device 500C only needs to have a mechanism capable of rotating around the fixed shaft 31 as a central axis. Therefore, it is possible to further simplify the mechanism of the rotation control device 500C. FIG. 7(B) shows a state in which the attachment 43 is rotated by 180° with the fixed shaft 31 as the central axis. The first structure demolition unit 400B has a width that can be accommodated in the space 32 of the arm 30B. Therefore, the first structure dismantling unit 400B can be accommodated in the space 32 only by rotating the attachment 43 without rotating the first structure dismantling unit 400B.

This embodiment is particularly effective when the structure dismantling unit can be accommodated in the arm without rotating. Since the mechanism of the rotation control device for the attachment can be simplified, the number of parts of the rotation control device can be reduced and the size can be reduced. Also, the cost of the attachment can be suppressed. Furthermore, since the arm of the demolition device 3 is also provided with a pivot shaft, the direction of the arm component of the structure demolition unit can be adjusted.

<Fourth Embodiment>

The attachment 44 shown in FIGS. 8A and 8B is in a state where the second crushing arm 437 is lifted close to the arm 30 . In this state, the attachment 44 can function as the first structure demolition unit 430A. In the first structure dismantling unit 430A, the first fork arm 434 and the first crushing arm 436 rotate about the first arm rotating shaft 432 as the central axis. Also, the second crushing arm 437 is fixed, and the second fork arm 435 rotates about the second arm rotation shaft 433 as a central axis. By opening and closing the first fork arm 434 and the first crushing arm 436 and the second fork arm 435, the crushed material can be grasped. That is, the first structure demolition unit 430A can function as a fork unit.

Next, the second structure dismantling unit 430B will be described with reference to FIG. 9A is a front view of the attachment 44, and FIG. 9B is a left side view of the attachment 44. FIG.

The attachment 44 shown in FIGS. 9A and 9B is in a state in which the second crushing arm 437 is lowered and the first fork arm 434 and the second fork arm 435 are raised close to the arm 30. FIG.

For example, as shown in FIG. 11(A), the tip of the cutter 442 may be provided with unevenness, and as shown in FIG. The tip may be provided obliquely. Furthermore, as shown in FIG. 11(C), the tip of the cutter 442 may be curved instead of straight. With the cutter 442 shown in FIGS. 11A to 11C, the area in contact with the structure to be demolished increases, so the area that can be worked on at one time increases, improving work efficiency.

Ultrasonic cutters are excellent in cutting plastics such as urethane foam, polyurethane, and polystyrene used in interior materials, as well as glass and paper, by vibration, heat generation, or frictional heat. Therefore, it is possible to dismantle the interior materials, which has conventionally been performed manually, by using the dismantling device 1 having the first structure dismantling unit 440 . Concrete, reinforcing bars, steel frames, etc. may be pulverized using an ultrasonic cutter.

According to this embodiment, not only the reinforced concrete contained in the outer wall but also the interior material such as urethane foam can be dismantled using a single dismantling device. Therefore, the working efficiency of the dismantling work is improved. In addition, by functioning as an ultrasonic cutter, only the interior material can be dismantled, making it easy to separate the pulverized material.
