Description

[Detailed Description of the Invention] [Industrial field of application] The purpose of this invention is to apply vibration to placed concrete or backfilled soil to fill concrete in every corner and compact it. The present invention relates to a compaction device.

[Prior Art] As a compaction device for secondary concrete products, a vibration mechanism utilizing the rotation of an eccentric weight is provided in a hollow rod-shaped compaction member, and a drive device of this vibration mechanism is provided at the upper end of the compaction member. There is something.

In such a conventional apparatus, a compaction member is inserted into concrete poured into a mold or the like, and the compaction member is vibrated to compact the concrete.

Further, there is also one in which a rod-shaped compaction member is fixed to the lower end of a vibrator, and this compaction member is inserted into concrete to vibrate vertically.

[Problems to be solved by the device]

Among the conventional compacting devices as described above, those having the rotary vibration mechanism in the hollow compacting member cannot be made very thin.

In order to obtain a large vibration force, the eccentric weight must be rotated at a high speed, resulting in a complicated structure, and the compaction member cannot be made too thin and its shape is limited.

There is also a problem that the thicker the compacting member is, the insufficient compaction of concrete or the like at the insertion site becomes.

Further, the conventional one provided with a vertically vibrating rod-shaped compaction member at the bottom of the vibrator is for manual operation, and has an advantage that it can be moved to any place and compacted. There is a problem that it cannot be made large because it is carried by a worker.

An object of the present invention is to solve the problems of the conventional compacting device as described above, and to provide a compacting device that uses a rod-shaped compacting member and is large in size and movable.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention installs a bracket, which can be freely swung by a driving means, at the tip of a boom such as a power shovel, and the bracket has a downward U-shape that swivels freely by a swivel device. A structure was adopted in which a swivel frame was provided, a vibrator was attached inside this swivel frame via left and right anti-vibration rubbers, and a rod-shaped compaction member was fixed to the lower part of this vibrator.

[Action]

Since the present invention has the above-mentioned configuration, it is attached to the tip of a boom such as a power shovel, the compaction member is inserted into the target concrete or the like, and the compaction member is vibrated by the vibrator to perform compaction.

At this time, the rod-shaped compaction member is freely manipulated by raising and lowering the boom, swinging the brat, swinging the swivel frame by the swivel device, and compacting at any desired location.

〔Example〕

In the embodiment shown in the drawings, reference numeral 1 is a boom such as a power shovel (not shown), and a hydraulic cylinder portion 3 is fixed to a bracket 2 which is swingably attached to the tip of the boom.

An elevating frame 4 that is moved up and down by the hydraulic cylinder is provided below the hydraulic cylinder unit 3, and a swivel frame 6 driven by a swivel device 5 such as a hydraulic motor is provided below the elevating frame 4.

The swivel frame 6 has a downward U-shape as shown in FIG. 2, and a vibrator 8 is mounted in the frame 6 via left and right antivibration rubbers 7.

In the vibrator 8, a pair of left and right rotating shafts (not shown) arranged in parallel inside the case are interlocked by gears so as to rotate in opposite directions, and an eccentric weight is fixed to both the shafts. One of the rotating shafts is rotated by a hydraulic motor to vertically vibrate, but the one that uses the reciprocating motion of the piston to vertically vibrate and any other structure than these. Vibration machine can be used.

A bracket 9 is fixed to the lower portion of the vibrator 8 and a rod-shaped compaction member 10 is fixed to the bracket 9.

In the illustrated example, three compacting members 10 are arranged in two rows to form a total of six compacting members 10, but each member 10 can be detachably attached by means such as screwing to the bracket 9 to increase or decrease the number of attachments. .

In the embodiment, a plurality of protrusions 11 are provided on the outer side of the member 10, but there may be no protrusions.

In addition to the above, various members 10 having different lengths, different thicknesses, or various shapes such as a linear shape, a curved shape, and a flat plate shape according to the shape of the compacted portion are prepared, and the member 10 is replaced as necessary. To use.

Further, the bracket 2 at the tip of the boom 1 has a link mechanism 12
The tilt angle can be freely changed by driving the hydraulic cylinder 13 or the hydraulic cylinder 13.

In the above embodiment, the compaction member 10 is arbitrarily set by changing the inclination angle of the cylinder portion 3 by operating the boom 1 and the link mechanism 12, raising and lowering the elevating frame 4 by the cylinder portion 3 and turning the revolving frame 6 by the revolving device 5. The member 10 is vibrated in a desired position and orientation by the vibrator 8 to compact concrete or the like.

[Effect of device]

Since the compaction device of the present invention is attached to the tip of a boom such as a power shovel, a large compaction device that cannot be manually operated can be configured.

In addition, the compaction member can be freely moved to any desired position by moving the boom up and down or the bracket, and when the compaction member has a plurality of compaction members or has a curved or flat compaction member. By rotating the swivel frame, the compaction member can be oriented in any direction, and the compaction member can be sufficiently compacted by inserting it into a portion that cannot be reached by the conventional compaction device. Since the swivel frame has a downward U-shape and has a structure in which a vibrator is attached via a vibration-proof rubber inside, there is an effect that even a large vibrator does not interfere with the operation.
