Description

[Detailed description of the device]

[0001]

[Industrial applications]

 TECHNICAL FIELD The present invention relates to a masonry work apparatus for constructing earth retaining walls such as retaining walls by stacking stone materials, particularly concrete blocks for masonry.

[0002]

[Prior art]

 In the conventional masonry work, all blocks were manually transported to the site and installed in place. In particular, one block weighs as much as 60 kg, and the labor of the workers had to be said to be severe. In addition, masonry work is often done at high places, which is extremely dangerous.

In order to solve these problems, a masonry working apparatus has recently been developed in which a block gripping device is attached to the arm tip of a base machine.

However, in general, the masonry work may be performed by placing the base machine above the retaining wall or below the retaining wall, and it is a condition that one machine can be used for both.

However, the conventional device described above has a problem in that not only the above conditions cannot be satisfied, but also it is not possible to cope only with the elevation movement of the boom, arm, etc. equipped on the base machine.

[0006]

[Problems to be solved by the device]

 The present invention was made in order to solve the above-mentioned conventional problems, and the purpose thereof is to carry out masonry work from both the upper side and the lower side of the retaining wall by one base machine. The purpose is to provide a masonry work device that can improve work efficiency, speed, and economic efficiency.

[0007]

[Means for Solving the Problems]

 The masonry working apparatus of the present invention is provided with an arm for pivoting and raising / lowering motions on a base machine that travels and moves, a slide arm is slidably attached to the arm, and a bracket is swingably attached to the tip end of the slide arm. , A board is rotatably attached to the bracket via a turning bear ring, a block gripping device is installed on a turning center line of the board, and a bucket is mounted back to back on the board of the block gripping device. .

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 is a base machine in which an upper revolving structure 1b is revolving with respect to a lower traveling structure 1a.

A boom 2 is pivotally attached to the upper swing body 1b of the base machine 1 by a pivot shaft 2a. Therefore, the boom 2 can be moved up and down (rotated in the vertical direction) about the pivot shaft 2a by the cylinder 3.

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 by the cylinder 5 about the pivot shaft 4a.

Reference numeral 6 denotes a slide arm, which is slidably mounted along the arm 4 and is configured to be slidable in a longitudinal direction of the arm 4 by a cylinder 7. As described above, the slide arm 6 has a function of substantially expanding and contracting the length of the arm 4.

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

As is apparent from FIG. 2, a substrate 11 is rotatably attached to the bracket 8 via a slewing bearing 10. The substrate 11 is rotationally driven by a hydraulic motor 12 and is appropriately locked at a turning position by a turning lock 13.

As is apparent from FIG. 3, a pair of grip claws 14, 14 are pivotally attached to the substrate 11 by pins 14 a, 14 a. The grip claws 14 are installed on the center line of rotation of the substrate 11. Both gripping claws 14, 14 are connected to each other by a link member 15.

Therefore, when the one (right side in FIG. 3) gripping claw 14 is operated by the hydraulic cylinder 16, the other (same left side) gripping claw 14 is moved in the opposite direction via the link member 15. Both gripping claws 14 operate in a direction in which they approach each other (a direction in which the block B is gripped) or in a direction in which they depart (a direction in which the block B is separated).

In FIG. 2, reference numeral 17 denotes a bucket, which is detachably attached to the substrate 11 by a bucket attachment / detachment pin 18 or the like with its back facing the gripping claw 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, the masonry work by the above apparatus will be described. First, the blocks B are arranged on the pallet 19 and transported to the masonry site. Upon arrival at the site, the block B is gripped by the grip claws 14 as shown in FIG. When gripping the block B, as shown in FIG. 3, the rod of the hydraulic cylinder 16 is retracted so that the gripping pawls 14 and 14 are opened and approached from above the block B. When positioned on both sides, the rod of the hydraulic cylinder 16 is extended, and the grip claw 14 is operated from the phantom line state to the solid line state to firmly hold the block B. The pallet 19 may be slid forward so that it can be easily grasped, if necessary.

When the grip claws 14 grip the block B, the slide arm 6 is slid upward to lift the block B from the pallet 19 and move the block B to a required installation position. When moving the block B, the base machine 1 is moved by the lower traveling body 1a, the upper revolving body 1b is revolved, and the boom 2, the arm 4 and the like are appropriately operated, as necessary.

Further, the slide arm 6 is appropriately slid to position the block B at a predetermined stationary position. Further, the substrate 11 may be rotated by the hydraulic motor 12 in order to orient the block B in a necessary direction.

When the blocks B are set aside in a row by repeating the above operation, the backfill concrete is put into the bucket 17, and as shown in FIG. 5, the backfill concrete is poured from the bucket 17 to the back side of the block B. Also in this backfill concrete work, the slide arm 6 is appropriately slid to position the bucket 17 at the optimum position.

FIG. 6 shows a masonry work state from the upper part of the retaining wall, and FIG. 7 shows a masonry work from the lower part of the retaining wall.

[Effect of device]

 1) An arm that swings and raises and lowers is provided on a moving base machine, a slide arm is slidably mounted on the arm, a bracket is swingably mounted on the tip of the slide arm, and a swing bearing is mounted on the bracket. The board can be attached via the rotator and the block gripping device is installed on the center line of rotation of the board, so the position and orientation of the gripped block can be easily set without excessive movement of the base machine or arm. It can be delivered accurately and accurately. 2) Backfilling Since the bucket for concrete pouring was attached to the base plate of the block gripping device in a back-to-back position, the baseboard can be swung as appropriate to open the bucket when the base machine is below the retaining wall. Towards the outside, if the base machine is above the retaining wall, the bucket can be turned to the inside (front side) to efficiently backfill the concrete.
