Description

  The present invention relates to a strut embedding device that embeds a strut such as a guard fence mainly by rotary press-fitting or striking. Moreover, this apparatus can also be used as a column pulling device for pulling out the column. Furthermore, this apparatus is applicable also as an embedding apparatus of the small diameter pile used for foundations, such as a building structure.

  Conventionally, a hitting method using a hammer or the like is generally used as a method for installing the protective fence column (for example, Patent Documents 1, 2, and 3). That is, as shown in FIG. 6, the pile head protection cylinder portion 50 is placed on the head of the column A, and the column A is driven into the ground by hitting with a hammer or the like.

As a method other than the above-described hitting, a “rotating column embedding method and a movable column rotating embedding device” in which a column is embedded by rotary press-fitting has been proposed (for example, Patent Documents 4 and 5).
Japanese Utility Model Publication No. 3-128728 Japanese Utility Model Publication No. 6-1439 Japanese Utility Model Publication No. 7-4538 JP 2003-155745 A Japanese Patent Application Laid-Open No. 2004-233883

In the case of the conventional method for embedding a protective fence post as described above, there are the following problems.
(1) In the embedding method using the hammering method using a hammer or the like, noise is generated because the head of the metal strut A is hit with the pile head protection cylinder portion 50 or the like (see FIG. 6). In particular, it is necessary to consider burial in urban areas.
(2) Although the noise can be reduced in the construction that is buried by rotary press-fitting, the rotary press-fit can be difficult if the ground where the support is installed is hard.
(3) In general, the impact method is faster than the rotary press-fitting method. For daytime construction, it is reasonable to use the striking method, and for nighttime construction with strict noise regulations, it is reasonable to use the rotary press-in method. Necessary, and construction costs such as equipment lease fees and loss fees will increase.
(4) New pillars may be buried after the existing pillars are pulled out for maintenance of the protective fence. Normally, the struts are pulled out by heavy machinery and embedded in a batting method, but two construction devices are required, and the construction costs such as lease fees and loss fees for the devices increase. Also, when pulling out, it may be difficult to pull out by simply pulling.

  The present invention has been made to solve the above-mentioned problems, and can suppress noise during embedding when continuously embedding small-diameter struts such as protective fence struts. The purpose is to provide a column embedding device that can rationally pull out and embed a column in maintenance work or the like.

  Claim 1 of the present invention is a rotary embedding device for embedding a strut (a strut such as a guard fence, a small-diameter pile of a foundation, etc., the same applies hereinafter), and is embedded in a movable vehicle so as to be able to turn horizontally. A strut embedment device comprising a machine base, a guide device that can be raised and lowered on the embedment machine base, and a rotary drive device and a striking force generator that can be moved up and down by the guide device. . The rotary drive device is a device that applies a rotational force around an axis to a support column, and a rotary head that is detachably attached to the head of the support column is provided at the tip of the rotary drive shaft. The striking force generating device applies striking force in the axial direction to the strut, and a striking head having a pile head protection cylinder portion that is detachably attached to the head of the strut is provided at the tip of the operating shaft. Yes. These rotary drive device and impact force generating device are housed in parallel in the casing.

  This claim 1 has both functions of a method of embedding a support post such as a protective fence while being rotationally press-fitted, and a method of embedding by striking, and a mobile type for installing the lower part of the support column by burying it at a predetermined depth. This is a strut embedding device, which is mounted on a traveling vehicle such as a light truck so that it can be continuously embedded along the road alignment in the same manner as a driving machine that is a current construction device. Moreover, the mounted apparatus is made to be able to turn horizontally in a predetermined direction in which the column is embedded. The guide device includes, for example, a guide that is raised and lowered by a hydraulic cylinder for raising and lowering. The rotation drive device and the impact force generation device are driven by a hydraulic motor or the like, and are attached to a guide device so that they can be pushed.

  Claim 2 of the present invention is a rotary embedding device for embedding a strut, and an embedding machine base that is mounted on a movable vehicle so as to be able to turn horizontally, and a guide that can be raised and lowered on the embedding machine base. And a slide cylinder for sliding the guide, a movable member movable along the guide, and a rotary drive device and a striking force generator provided on the movable member. is there.

  The second aspect of the present invention is a case where the guide is slid only, and the rotational drive device and the striking force generator are moved along the guide, and the guide is slid by the slide cylinder so as to rotate. Is pushed downward.

  According to a third aspect of the present invention, there is provided the post embedding device according to the first or second aspect, wherein the guide device has a swinging structure with respect to the vertical direction.

  According to the third aspect of the present invention, since the standing guide device can be tilted with respect to the vertical direction, that is, swingable, the column can be installed vertically even when the road has a longitudinal gradient or a transverse gradient. it can. For example, the tilt angle in the undulation direction is adjusted using a undulation cylinder or the like of the guide device, and the tilt angle in the direction perpendicular to the undulation is adjusted by an angle adjustment cylinder or the like attached to the guide device to swing the head.

  According to a fourth aspect of the present invention, in the post embedding device according to any one of the first to third aspects, the head of the post is detachably attached to the tip of the rotary drive shaft of the rotary drive device. The rotating head is provided with at least one notch groove for locking the locking projection of the head of the column in the chucking tube portion mounted so as to cover the head of the column. It is the pillar embedding device characterized by being.

  According to the fourth aspect of the present invention, when the rotary drive device is used, a chucking cylinder portion that covers the head portion of the support column over a predetermined length is provided at the lower portion of the rotation head, so that the support column can be stably provided during the press-fitting. It can be held. Further, the column head and the rotary head are detachably integrated with the notch groove and the locking projection so that the rotational force and the axial force can be transmitted. In addition, you may provide the buffer material (resin etc.) which protects a support | pillar between a chucking cylinder part and a support | pillar head. In addition, since the locking projection on the head of the column is composed of a rod-shaped member inserted into the through hole for attaching the member provided on the column head, there is no need to separately process the column and it is economical. is there.

  According to a fifth aspect of the present invention, in the pillar embedding device according to any one of the first to fourth aspects, a weight for preventing the vehicle from being lifted is placed on the vehicle (loading platform, strut embedding device, etc.). It is the pillar embedding device characterized by being.

  According to the fifth aspect of the present invention, when the strut is rotationally press-fitted by the rotary drive device or when the striking force generating device is used to embed the strut, the vehicle is lifted by the reaction force of the vertically downward pushing force or striking force against the strut. It is conceivable that sufficient pushing force and striking force cannot be applied and the construction ability is reduced. In this case, by placing a weight on the vehicle, lifting of the vehicle is suppressed and the construction speed is improved. In addition, the weight may be placed on the column embedding device itself or may be hung other than being placed on the loading platform of the vehicle.

  According to a sixth aspect of the present invention, in the post embedding device according to any one of the first to fifth aspects, the rotary head of the rotary drive device is arranged not only in the rotational direction of the post but also in the pull-out direction of the post. This is a strut embedding device characterized in that the structure is also locked.

  The sixth aspect of the present invention is a case where construction is performed using a rotary drive device, and the structure in which the rotary head is locked also in the column pull-out direction, that is, the shape of the notch groove of the chucking tube portion is only in the column rotation direction. First, by adopting a shape (for example, a saddle shape) that also locks in the pull-out direction of the column, the column can be pulled out by pulling up the guide device of the column embedding device while holding the column. That is, the column embedding device can also be used as a column pulling device. In addition, the pulling performance is significantly improved by pulling out while rotating, compared to the conventional method that does not rotate.

  In the present invention configured as described above, an embedded machine is mounted on a small and lightweight traveling vehicle such as a light truck, and the embedded machine that can be swung horizontally is rotated in the direction of a predetermined embedded position as necessary. The striking force generator is configured to push the rotational drive device downward with the guide device while rotating the rotary drive device, embed the lower portion of the column by the rotary press-fitting method, or apply the striking force from the striking force generator to the striking head. Is pushed downward by the guide device, and the lower part of the column is buried by the striking method. This operation is repeated while moving the vehicle, and in the case of a protective fence, the columns are continuously embedded along the road alignment. By adopting a swing structure for the guide device, it is possible to install the support column vertically even when the road alignment has a longitudinal gradient or a crossing gradient. The rotary press-in method is used in the case where the ground is not hard or night construction with strict noise regulations, and the batting method is used in the case where the ground is hard or during daytime construction. In order to prevent the vehicle from lifting when the column is buried, work is carried out with a weight placed on the vehicle.

  In the rotary press-fitting method, if the notch groove for locking the locking projection on the column head is provided in the chucking cylinder part below the rotating head, the rotating head can be easily attached to and detached from the column head, and the rotational force Axial force can be transmitted reliably. Furthermore, when the column is updated for maintenance or the like, the column can be pulled up while being rotated by using the column embedding device if the notch groove is also locked in the column pulling direction.

  (1) Since a compact and lightweight traveling vehicle is equipped with an embedded machine that has both rotary press-in and blow-in functions, the rotary press-in method reduces noise during construction compared to the blow-in type. In addition, when the ground on which the support is installed is hard, it can be easily switched to the striking method, and quick embedding can be performed by the striking method.

  (2) Since the rotary press-fitting method and the striking method can be used together, rational construction is possible, such as using the striking method for daytime construction and the rotary press-fitting method for nighttime construction with strict noise regulations. Thus, the construction cost can be reduced.

  (3) By using a structure in which the rotary head of the rotary drive device can also support the column pull-out, the column embedding device can be used as the column pull-out device. When updating the support for maintenance or the like, the existing support can be easily pulled out while rotating. Moreover, after pulling out, a new support | pillar can be embed | buried by rotation press-fitting or hammering, without replacing a construction apparatus. Thereby, construction time can be significantly shortened and construction costs can be reduced.

  (4) By adopting a swinging structure for the guide device, it is possible to install the support column vertically even when the road alignment has a longitudinal or transverse gradient. On the contrary, it is also possible to embed the column by inclining the column.

  (5) By placing a weight on the loading platform of the vehicle and this device, it is possible to suppress the lifting of the vehicle at the time of embedding the column, and to apply sufficient pushing force and striking force to the column, thereby improving the construction speed.
