Abstract

PURPOSE:To permit stone masonry work to be performed with only one machine by a method in which swivel and devicking arm is attached to a traveling base machine, and a block holder and a bucket are rotatably attached to the tip of the arm in such a way as to enable a base plate to be locked on an adequate position. CONSTITUTION:A bracket 8 is pivotally attached to the tip of a slide arm 6, a base plate 11 is rotatably attached through a swivel bearing 10, and the plate 11 to be rotationally operated by an oil-pressure motor 12 is locked on an adequate turning position by a swivel lock 13. The base plate 11 is provided with a pair of holding claws 14 connected by a link part 15 by which blocks B are grasped by a oil-pressure cylinder 16. A bucket 17 is also detachably attached to the base plate 11. The blocks B are grasped by the claws 14 on the construction site and set in a row, and concrete is placed from the bucket 17 to the back side of the blocks B to construct the back-filling concrete.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a masonry work device for building a retaining wall such as a retaining wall by stacking stones, particularly concrete blocks for masonry.

[Prior art and its problems] In conventional masonry work, blocks were transported to the site and installed at a predetermined position by hand.

In particular, there are blocks that weigh up to 60 kg each.
It must be said that the labor of the workers was harsh.

Additionally, masonry work often involved work at heights, which was extremely dangerous.

In order to solve these problems, we recently started using the base machine 7.
- A masonry work device has been developed in which a block gripping device is attached to the tip of the masonry.

However, in general, masonry work must be carried out while backfilling concrete, so when backfilling concrete, the conventional device described above requires that the block gripping device be removed from the tip of the arm and the concrete be backfilled. It is necessary to replace the concrete backfilling bucket with a concrete backfilling bucket or use another special equipment having a concrete backfilling bucket, which causes problems such as complicated and time-consuming work and lack of efficiency.

[Objective of the Invention 1 The present invention was made in order to solve the above-mentioned conventional problems, and its purpose is to realize both the work of placing blocks and concrete backfilling with one machine, It is an object of the present invention to provide a stone masonry working device capable of speeding up work and improving efficiency.

[Structure 1 of the Invention The masonry work device of the present invention is characterized in that a base machine that travels is provided with an arm that rotates and moves upward and downward, and a block gripping device and a bucket are rotatably equipped at the tip of the arm. , the block gripping device and the bucket can be locked at appropriate rotational positions.

[Embodiment 1] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a base machine, and an upper rotating body 1b rotates with respect to a lower traveling body 1a.

The upper rotating body 1b of the base machine 1 has a pivot shaft 2a.
The boom 2 is pivotally attached by. Therefore, the boom 2 is elevated (raised and raised) about the pivot shaft 2a by Schilling-3.
It is designed to be able to rotate (up and down).

Further, an arm 4 is pivotally attached to the tip of the boom 2 by a pivot shaft 4a. Therefore, the arm 4 can be moved up and down about the pivot shaft 4a by the sill-5.

Reference numeral 6 denotes a slide arm, which is attached to be slidable along the arm 4, and can be slid telescopically in the longitudinal direction of the arm 4 by means of a cylinder 7.

As described above, the slide arm 6 has the function of substantially extending and contracting the length of the arm 4, so the slide arm 6 is also included in the arms constituting the present invention as necessary.

A bracket 8 is pivotally attached to the tip of the slide arm 6 by a pivot shaft 8a. The bracket 8 is rotated by a hydraulic cylinder 9.

As is clear from Figure 2, a substrate 11 is rotatably attached to the bracket 8 via a swing bearing 10. The substrate 11 is rotationally driven by a picture pressure motor 12, and is locked at an appropriate rotational position by a rotation lock 13.

As is clear from FIG. 3, the substrate 11 has a bottle 14.
a, 1 (a) pivots a pair of gripping claws 14, 14, and both gripping claws 14, 14 are mutually connected by a link member 15. Therefore, the hydraulic sill -16
When one of the gripping claws 14 (on the right side in FIG. 3) is operated, the other gripping claw 14 (on the left side in FIG. 3) moves in the opposite direction, that is, both gripping claws 14 approach each other via the link member 15. It operates in the direction (to grip the block B) or in the release direction (to release the block B).

In FIG. 2, reference numeral 17 denotes a bucket, which is detachably attached to the substrate 11 by means of a bucket attachment/detachment pin 18 or the like with its back facing the gripping claws 14.

As shown in FIG. 1, a pallet 19 is provided on the frame of the lower traveling body 1a of the base machine 1.

Next, masonry work using the above device will be described.

First, the blocks B are arranged on a pallet 19 and transported to a masonry site.

When arriving at the site, the gripping claws 14 grip the block B as shown in FIG. 4. To grip the block B, as shown in FIG. Block B is approached from above in the open state, and when the gripping claws 14 are positioned on both sides of block B, the rod of the hydraulic sill 16 is extended to operate the gripping claws 14 from the imaginary line state to the solid line state. hand,
Hold block B firmly.

Note that, if necessary, the pallet 19 may be slid forward to make it easier to grip.

When the gripping claw 14 grips the block B, the slide arm 6
Slide upward to pull up block B from pallet 19 and move block B to the required installation position.

When moving this block B, the base machine 1 is moved by the lower traveling body 1a, the upper rotating body 1b is rotated, and the boom 2, arm 4, slide arm 6, etc. are operated as appropriate.

Also, in order to orient block B in the required direction,
The substrate 11 may be rotated by the hydraulic motor 12.

After repeating the above fabrication and placing the blocks B in a row, fill the bucket 17 with backfill concrete, and pour the backfill concrete from the bucket 17 onto the back side of the blocks B as shown in FIG.

Figure 6 shows the masonry work from the top of the 4I wall, and the 7th
The figure shows masonry work from the bottom of wall 41.

[Effect of the invention 1 (1) Since the block gripping device and the bucket can be rotated, it is possible to immediately switch between the block placement work and the backfill concrete casting work as needed, which greatly improves work efficiency. improved.

(2) Multi-functionality of block placement and backfill concrete pouring work was realized with one machine.

(3) Freed up harsh and unsafe working tools.

(4) Economical efficiency has been improved because it is possible to speed up the process, including labor saving on working tools.
