Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for taking a rotational reaction force of a tubing device that pushes a casing tube into a ground while rotating it.

[0002]

2. Description of the Related Art As a construction of a cast-in-place pile, a tubing device pushes a casing tube having an excavating blade at the lower end of the casing into the ground while rotating or rocking the casing tube, and the earth and sand in the casing tube is moved by a mobile crane equipped with a hammer mag. There is known an all-casing construction method in which a casing is discharged by discharging a stake, a pile is built inside, and a casing tube is collected.

Conventionally, various devices have been put into practical use as a device for taking the reaction force of the rotational drive of the tubing device, but in the work of the tubing device, a working machine for discharging the earth and sand in the casing tube is shown in FIG. The mobile crane equipped with the hammer mug 33 as shown in () is generally used, and it can be said that it is convenient and easy to work with it to perform reaction force recovery.

[0004] As a typical example, the actual Kaihei 1-1056
No. 45, wherein one end of the beam is swingably attached to the base frame of the casing tube, and the other end of the beam is brought into contact with the end surface or the track surface of the crawler of the working machine. 3-5
As disclosed in No. 2262, one end of a beam is detachably attached to a base frame of a tubing device, and the other end is connected to a track frame of a working machine by a pin.

[0005]

However, since it is necessary for the working machine to perform the work for discharging the earth and sand in the casing tube, it may be difficult to install the rotary reaction force removing device. For example, in the operation of a commonly used hammer mug, the hammer mag is dropped in order to bite it into the earth and sand, and the boom is raised when it falls, so the angle of the crane boom cannot be increased. Therefore, the Hammaglab fuselage is operating far away from the tubing equipment.

[0006] Further, since the amount of discharged soil per one time of the hammer mug is small, in the soft ground, the earth and sand in the casing tube are also discharged by an earth drill as shown in Fig. 8 (b). In this case, since the angle of the boom 32 cannot be reduced due to the positional relationship of the rotary drive mechanism 35 that rotates the kelly bar 34 with the bucket 36 attached, the body of the earth drill is placed near the tubing device for work.

Some rotary reaction force removing devices have a double beam structure so that the beam can be expanded and contracted even if the distance between the tubing device and the working machine is different. The difference is more than 2m,
The double-structured beam is large and heavy, which makes it difficult to handle.Besides, it is necessary for the beams to overlap to some extent even when extended to the maximum extent, so even when the beam is reduced to the maximum, it is considerably The length of the ground drill is too close to the tubing device. Therefore, generally, a rotary reaction force removing device corresponding to each of the hammer grill and the earth drill is separately prepared.

However, in actual work, there are many cases where the hard ground layer and the soft ground layer are intricately mixed, and according to the ground, the hammer drill and earth drill are used properly for soil removal work, and every time the working machine is changed, Since I have to replace the rotary reaction force removing device, if I spend a lot of time on this,
There is no point in changing the work equipment.

Therefore, an object of the present invention is to provide a rotary reaction force removing device for a tubing device which is easy to handle and can be used even when the distance between the working machine and the tubing device changes greatly.

[0010]

The rotary reaction force removing device of the tubing device of the present invention uses a working machine for discharging the earth and sand in the casing tube as a reaction force support. The tubing device can be applied to either a rotary type or a swing type.

[0011] The working machine includes not only a crawler traveling crane equipped with working tools such as a hammer mug and down the hole hammer, but also an earth drill and an earth drill equipped with a hammer mag. According to a first aspect of the present invention, in a rotary reaction force removing device for a tubing device that pushes into the ground while rotating or rocking a casing tube, a bracket that supports a beam on one end surface of a base frame of the tubing device so as to be slidable in the longitudinal direction. Is provided, and one end side of the beam is supported by the bracket, and the other end of the beam is detachably connected to a track frame of a working machine for discharging the earth and sand in the casing tube.

The bracket is only required to be capable of slidably supporting the beam, and preferably has a tubular shape or a U-shaped cross section so that the beam can be inserted therethrough. The bracket need not be attached to the entire length of one surface of the tubing device. Further, it is desirable that the upper surface of the bracket be flat so that a weight for taking a reaction force against the pushing of the tubing device can be placed.

The shape of the beam is not particularly limited,
Since the one end side supported by the tubing device slides, it is desirable to make it into a rectangular tubular shape with the same cross section. The beam and the working machine may be connected to each other as long as they are detachable, and may be connected by a pin or may be fitted by concavity and convexity. In the case of pin connection, if the pins are arranged in the vertical direction, the angle of the working machine with respect to the beam can be arbitrarily set, which is effective in a narrow construction site.

According to the present invention, when the working machine and the tubing apparatus are short in distance, the beam is supported in a state of penetrating the bracket and protruding rearward. It should be noted that it is desirable to connect the beam to the bracket with a pin because rotation reaction force becomes large in the hard ground. According to a second aspect of the present invention, in a rotation reaction force removing device for a tubing device that pushes into the ground while rotating or rocking a casing tube, one end side of the beam is connected to one end face of a base frame of the tubing device, and It is characterized in that a slidable slide bracket is provided on the end side so that the beam can be fitted onto the slidable bracket, and the slide bracket is detachably connected to a track frame of a working machine for discharging the earth and sand in the casing tube.

The difference from the invention of claim 1 is that one end side of the beam is only detachably connected to the tubing device and cannot be slid, and the other end side of the beam is connected to the tubing device through a slide bracket to set an arbitrary length of the beam. The point is that it can be connected to the work machine at the position of the height. Therefore, claim 1
In the case of the invention of claim 2, when the distance between the tubing device and the working machine becomes small, the beam penetrates the bracket attached to the tubing device and projects rearward (on the side opposite to the working machine side). In the case of, it will invade the lower part of the truck frame of the working machine.

The attachment of the beam to the tubing device may be arbitrary. For example, the beam may be connected by a pin along one end surface of the tubing device, or a bracket may be provided on one end surface of the tubing device so that the beam is connected at right angles to the one end surface of the tubing device. .

According to a third aspect of the present invention, in a rotational reaction force removing device for a tubing device that pushes into the ground while rotating or rocking a casing tube, a beam is slidable in the longitudinal direction on one end surface of a base frame of the tubing device. A bracket for supporting is provided, one end side of the beam is supported by the bracket, and a slide bracket which is slidable by externally fitting the beam is provided at the other end side of the beam, and the slide bracket discharges the earth and sand in the casing tube. It is characterized by being detachably connected to the truck frame of the work machine.

The difference from the inventions of claims 1 and 2 is that the inventions of claims 1 and 2 slidably support one end or the other end of the beam.
The invention of claim 3 is such that both the one end side and the other end side of the beam can be slid. According to the present invention, the rotational reaction force removing device can be attached even when only one of the tubing devices can be projected, for example, when the tubing device is placed near a wall and the beam cannot be projected rearward. The slide mechanism on the one end side and the other end side may be the same as the means of claims 1 and 2.
