Description

[Detailed description of the invention] The present invention is a shock absorber for a deep vibration compaction machine, specifically, a deep vibration compaction device that transmits vertical vibrations caused by an exciter to the deep vibration compaction machine. Drive the machine to the required depth,
On the other hand, the present invention relates to a shock absorbing device for absorbing horizontal vibrations of a deep vibration compaction machine.

Conventional shock absorbers of this type are configured to mainly absorb and absorb horizontal vibrations, and are not configured to receive vertical vibrations of an exciter.

Therefore, there is a problem in receiving the above-mentioned vertical vibration.

The present invention aims to provide a deep vibration compaction lateral shock absorber that solves the above problems.

In the present invention, a first flange member is attached to the lower surface of a vibration exciter, a second flange member is attached to the upper surface of a deep vibration compaction machine, and the first flange member and the second flange member are connected by a connecting tool. , a buffer member is interposed between at least one of the upper surface of the first flange member and the lower surface of the second flange member and the connector, and between the first flange member and the second flange member. The present invention is characterized in that the buffer member receives vertical vibrations of the first flange member and transmits them to the second flange member, while absorbing and absorbing horizontal vibrations of the second flange member.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the deep vibration compaction lateral shock absorber according to the present invention will be described below with reference to the accompanying drawings.

In this embodiment, the deep vibration compaction horizontal shock absorber of the present invention has a first flange member 29 attached to the lower surface of the exciter 28.
, the 27th lunge member 30 attached to the top surface of the deep vibration compaction machine 4, the 17th lunge member 29, and the 27th lunge member 3.
0, and the first flange member 29 and the second flange member 30 are connected to each other through the first buffer member 31 and the second buffer member 32. A connecting tool consisting of a connected port 33, washer 34, and nut 35 is provided.

The deep vibration compaction machine 4 has an eccentric shaft supported in an elongated casing, and also has a built-in drive motor.The drive motor and the eccentric shaft are linked, and by driving the drive motor, the eccentric shaft is rotated. It is configured to obtain horizontal vibration.

The first flange member 29 and the second flange member 30
The mounting flange portions 3 are provided at both upper and lower ends of the cylindrical body portion 36.
7 and the buffer flange portion 38 are fixed by welding, and the buffer flange portion 38 and the mounting flange portion 37 are fixed by welding.
Reinforcing brackets 39 are fixed by welding at equal intervals between the two.

Through holes 40 having a diameter slightly larger than the diameter of the bolts 33 are provided between the brackets 390 of the buffer flange portion 38, and through holes 41 are formed at equal pitches in the mounting flange portion 37.
Provide two.

The mounting flange portion 37 of the first flange member 29 thus formed is attached to the lower surface of the vibrator 28, and the mounting flange portion 37 of the second flange member 30 is attached to the upper surface of the deep vibration compaction machine 4.

The buffer member is made of urethane rubber or the like, has a through hole in the center with a diameter slightly larger than the diameter of the bolt 33, and has a relatively thin first buffer member 31 and a hole in the center with a diameter slightly larger than the diameter of the bolt 33. The second buffer member 32 has a through hole, is relatively thick, and has collars 42 fitted on both upper and lower ends.

The second buffer member 32 is interposed between the seven buffer flange portions 38 of the first flange member 29 and the buffer flange portion 38 of the second flange member 30, and the first flange member 29 and the second flange The first buffer member 31 is set on the outer surface of the buffer flange portion 38 of the member 30, and the first
A washer 34 is set on the outer surface of the buffer member 31, and a bolt 33 is inserted into the through hole of the washer 34, the first buffer member 31, the second buffer member 32, and the buffer flange portion 38,
By tightening the nut 35 on the port 33, the first flange member 29 and the second flange member 30 are connected via the buffer member 31, 32 with a connecting tool.

As a result, the first buffer member 31 is located between the upper surface of the first flange member 29 and the nut 35 screwed into the bolt 33.
It is interposed between the lower surface of the 27th flange member 30 and the head of the bolt 330.

The second buffer member 32 has a first flange member 29 and a second buffer member 32.
It is interposed between the flange member 30 and the flange member 30 .

Since the deep vibration compaction bale shock absorbing device of the present invention in this embodiment has the above configuration, the first flange member 2
The vertical vibration of the exciter 28 from 9 is received by the first buffer member 31 and the second buffer member 32, and the second flange member 30
transmitted to.

That is, the second buffer member 32 mainly receives the vertical vibration of the exciter 28.

On the other hand, when the second buffer member 32 is bent due to the vertical vibration of the exciter 28, the first buffer member 31 is located between the upper surface of the first flange member 29 and the nut 35 and the second flange member 300. A gap is created between the lower surface and the head of the bolt 330 to prevent damage to the flange members 29, 30, the bolt 33, and the nut 35 due to collision with each other.

On the other hand, the horizontal vibration of the deep vibration compaction machine 4 of the second flange member 30 is buffered and absorbed by the buffer members 31 and 32, and
It is not transmitted to the flange member 29.

In this embodiment, since the collars 42 are externally fitted on both upper and lower ends of the second buffer member 32, there is no fear that the second buffer member 32 will jump out laterally when it is bent.

Note that if the first buffer member 31 and the second buffer member 32 are directly bonded to the buffer flange portion 38 with an adhesive, the washer 34 becomes unnecessary.

In addition, in this embodiment, the first buffer member 31 is placed between the upper surface of the first flange member 29 and the nut 35, and the second
Although the lower surface of the flange member 30 and the nut 35 are interposed alternately, the upper surface of the first flange member 29 and the nut 35 are interposed alternately.
5 or between the second flange member 300 and the nut 35.

As is clear from the above embodiments, the deep vibration compaction bale shock absorbing device of the present invention has a first flange member attached to the bottom surface of the exciter, etc., and a second flange member attached to the top surface of the deep vibration compaction machine. the first flange member and the second flange member are connected by a connecting tool, and the first flange member and the second flange member are connected between the upper surface of the first flange member, the lower surface of the second flange member, and the connecting tool. Since a buffer member is interposed between each of the two flange members, the vertical vibration of the first flange member is received by the buffer member and transmitted to the second flange member, and on the other hand, the horizontal vibration of the second flange member is buffered and absorbed. be able to.

It also has the effect of being able to sufficiently withstand vertical vibrations of the exciter.

Note that, as a matter of course, the deep vibration compaction bale shock absorbing device of the present invention is not limited to the above-mentioned embodiments.
