2. Description of the Related Art For example, as shown in FIG. 11, a protective fence such as a guard rail is provided at the boundary between a roadway and a sidewalk to prevent falling and entry of a vehicle. In general, the guard rails are installed by inserting the lower half of the guard rail pipe 60 into the ground at intervals of 3 to 5 m, and then passing the guard rail plate 61 between the adjacent guard rail pipes 60, 60, the both ends of which are the guard rail. It is constructed by fixing the pipes 60, 60.

As a device for installing the guardrail pipe 60, a device shown in FIG. 10, for example, has been conventionally used. This guardrail pipe placing device is provided with a crane 53 for suspending a leader (guide cell) 52 on a truck body 51, an air breaker 55 is mounted on the leader 52, and the pneumatic breaker is mounted on the cargo bed surface thereof. A compressor 54 for driving 55 is provided. Further, an attachment that is fitted to the upper end of the guardrail pipe 60 is provided at the tip of the pneumatic breaker 55, and the pneumatic breaker is vibrated while the attachment is pressed against the head of the guardrail pipe 60. Pressing into the ground is performed by. A breaker installation table 56 is provided on the loading platform of the truck main body 51. As shown in FIG. 9, the leader 52 is stored in a folded state during movement, and the pneumatic breaker 55 is removed from the leader 52. It is placed on the breaker installation table 56.

The operation of placing a guardrail pipe by this guardrail pipe placing device will be outlined with reference to FIG. 10.

Normally, a vertical gradient is always formed on the road in the vehicle traveling direction, and about 2% for drainage or the like in the transverse direction of the road as shown in FIG. There is a degree of cross slope. On the other hand, the guardrail pipe is basically installed in the vertical direction (gravitational direction) regardless of the vertical slope or the transverse slope, but especially when the vertical slope is large, for the convenience of mounting the guardrail plate, the vertical surface In some cases, it is required to be installed perpendicular to the road surface, that is, in a state of being inclined with respect to the vertical direction by a vertical gradient.

However, in the case of the guardrail pipe burying device described above, the leader 52 connected to the tip of the crane 53 can be suspended only in the vertical direction (gravitational direction). After the lower end is brought into contact with the ground once, the inclination of the leader 52 must be adjusted by moving the crane 53 in the horizontal direction. Further, since this inclination adjustment is performed by the crane operation, highly accurate adjustment is possible. Not only is it difficult, but it is also a very complicated task. Further, even when the guardrail post is installed in the vertical direction, positioning is a three-dimensional operation due to the crane operation, so that there is a problem that positioning takes time.

On the other hand, in a punching machine using a crawler or the like as a base machine, the supporting structure of the guide cell is generally capable of undulating motion in a plane in one direction by a tilting cylinder arranged in a stay shape, but further in a vertical direction. There is no one that can adjust the tilt direction easily and quickly.

Therefore, the first object of the present invention is to provide a guide cell support structure, and a novel guide cell support structure for facilitating the adjustment of the inclination direction and the relationship with this support structure facilitate three-dimensional movement in any direction. Another object of the present invention is to provide a guide cell support structure capable of quickly adjusting the inclination of the guide cell, and a pipe placing and drilling device adopting the guide cell support structure.

[0009]

A guide cell support structure according to the present invention for solving the above-mentioned problems is provided with a swinging shaft for swinging about a member longitudinal axis in a substantially horizontal arrangement. A guide cell equipped with a breaker or a drifter is provided with the rotary shaft for use as a support member. In order to adjust the inclination in any direction three-dimensionally, in the guide cell support structure, the support structure of the guide cell with respect to the swing rotation shaft is further changed to the swing rotation shaft. One end of the guide cell is rotatably supported in the up-and-down direction, one end is rotatably connected to the swing rotation shaft side, and the other end is rotatably connected to the guide cell side. It is supported by the undulating cylinders in a fixed stay arrangement. As the rotation control means for the swing rotation shaft, various structures are conceivable.
For example, the rotation position can be controlled by a cylinder having one end connected to the turning base side and the other end connected to the swinging rotation shaft side.

Therefore, according to the guide cell support structure of the present invention, since the guide cell is supported by using the swing pivot shaft as a support member, it is possible to simply perform the pivot position control of the swing pivot shaft. The inclination of the guide cell can be adjusted. In addition, since the undulating operation of the cylinder for undulation can be performed by expanding and contracting the cylinder for undulation, the guide cells can be positioned three-dimensionally in any inclination direction easily and quickly.

On the other hand, the pipe placing and drilling device adopting the guide cell support structure is provided with a swivel base rotatable on a vertical axis on a traversable base machine, and the swivel base. A swing rotating shaft that is rotatable about a member longitudinal axis in a substantially horizontal arrangement is provided above, and a guide cell for mounting a breaker or a drifter is provided using the swing rotating shaft as a support member, and the swing The support structure of the guide cell with respect to the rotation axis for swing is pivotally supported on the one end side of the swing rotation axis so that the guide cell is rotatable in the up-and-down direction, and one end is rotated to the swing rotation axis side. The present invention is characterized in that it is supported by a stay-like undulating cylinder movably connected and the other end rotatably connected to the guide cell side.

Therefore, for example, when it is used for installing a guardrail post, the swivel base is set at about 90 °.
The guide cell is pivoted to the side of the machine body, and the undulating cylinder is extended to make the guide cell substantially upright. After that, for each post installation location, the in-plane tilt adjustment along the road extension direction by the swing adjustment of the swing rotation axis and the in-plane tilt adjustment along the road width direction by the expansion and contraction adjustment of the undulating cylinder are performed. After adjusting the guide cell to a desired inclination angle, the post is placed.

In this case, the swivel base is divided into a lower fixed base and an upper slide base, and the upper slide base is movable with respect to the fixed base. Even if there is some positional deviation in the state where the guide cell is positioned on the side of the post installation scheduled position, the guide cell can be easily positioned at the post installation scheduled position by moving the slide base.

Further, when the base machine is a wheel type or a crawler type, lateral support is not required due to the outriggers. When using a truck as a base machine as in the past, it is necessary to set outriggers at each post installation location, but in the case of wheel type or crawler type, outriggers are not required, so work efficiency can be improved. At the same time, it becomes possible to easily enter and work even on a rough road.

If the guide cell is provided with an inclinometer and the inclination of the guide cell is adjusted while looking at the inclinometer, the work efficiency can be further improved.
