10 cl, 5 dwg

The subject application is a device for manipulating and penetration into the soil Foundation devices, and/or pipes and/or excavation of the Boers under restrictive part of paragraph 1 of the claims.

Device for driving or screwing the base of the fixtures and pipes, or for drilling known. They are presented as separate, for example, self-propelled device with all the necessary guides (holding and orienting devices and actuators. As such they are targeted and very comfortable, but they are relatively expensive, as it is designed only for a certain type of penetration (for example, for driving or drilling, or screwing). They are profitable only in cases, when ever a large volume of the same work in depth.

For users with random demand in such works these devices are actually used only in the form of attachments for hanging on the well-known multi-purpose construction machines, for example, on an excavator boom. Only then will they be cost-effective for the user. Similar to the attached equipment described in US 6.942.430 B1 as a device for screwing pipes.

When using the known device is difficult maintaining healthy lifestyles specified is of screwing, whether vertical direction or direction under any other angle, in fact, throughout the entire process stages.

This is due, firstly, to the fact that the arrow on which is suspended a device for screwing that goes with the process of screwing. When the swivel tool for screwing the bolt moves along the curve around the axis of rotation arrows on the excavator. This means that the tool for screwing in, and with it furtively pipe or pile, or earth auger at the upper end, in the absence of correction, followed by the hinge connection and is deflected in the longitudinal direction of arrows from the given direction.

A similar error occurs in the lateral direction when the longitudinal axis svertyvaemost pipes are not in the same plane as the boom of an excavator, for example, due to the fact that the excavator, and together with him and his arrow (in the vertical direction of screwing), is located obliquely or, even if the excavator and stands erect, the direction of screwing differs from the vertical. Overlay such, as well as the above, sources of errors can lead to erroneous deviations svertyvaemost pipe in any direction.

It should be added, and other error sources, such as soil resistance under the action shall eat which furtively pipe deviates from the predetermined direction, and finally the error allowed by the driver of a construction machine, which can occur, particularly during attempts to repair errors described above orientation.

However, as described erroneous orientation, according to the prior art, are compensated primarily through the management of a construction machine or an arrow, and the driver of the construction machine, depending on the situation, sends it forward or backward or expands or shortens or lengthens the boom, or rotate it.

This procedure hides naturally serious sources of error, as the nature and the amount of correction set by the operator on the eyes and the precision of his movements management and technology (precision control). The fact that this accuracy, especially in rough terrain and taking into account prescribed for such work equipment, often leaves much to be desired, is obvious.

A partial solution to these problems is proposed in US 3,746,104. Here the arrow drilling device is made with hydraulically adjustable in length. In the result, there is no need to adjust the orientation by movement of the construction machine forward or backward, which is usually necessary, for example, to prevent displacement of the seat pivotally connect the deposits from the longitudinal axis of the drilling device when lowering the boom. The necessary correction is made by means of hydraulic changes the length of the boom instead of the hard provide precise motion control of the construction machine. However thanks to that can be solved only with the task associated with the error correction of the deviation in the longitudinal direction of the arrows, and even then not completely, as in the case when the bolt is located under other than a straight angle to the direction of screwing borax, any change in the length of the boom is associated simultaneously with the change of the height position. This leads, depending on the direction of motion, removing unwanted or indentations borax. Other errors of orientation must be compensated with this decision through appropriate maneuvers excavator, if necessary turning movements of the body of the excavator with all the associated disadvantages, or compensation is not possible and one has to accept this. First of all, this solution is costly because it requires arrows, quite different from the usual arrows.

Another partial solution is provided in AT 387424, which describes the combination of the cardan suspension of a drilling device with a hydraulic device for adjusting its length, than excluded boom and, consequently, the tie is installed with this problem.

It is true that the subject invention eliminates the problems caused by movements of the boom. To prevent other errors of orientation, which necessitates an additional adjustment device, this information source solution does not contain. And in this case also saved an additional adjustment by movement of the construction machine or the installation of the boom motions or have to put up with the wrong orientation.

Moreover, this device is also quite expensive and almost not used primarily for long Foundation fixtures/pipes/earth augers, as it requires the mounting height of the boom, which is almost impossible in the common types of construction machinery.

Therefore, the objective of the invention is to create a device for manipulating and penetration Foundation devices, and/or pipes and/or drilling, is used as mounted guns hanging on the boom of a construction machine, which is a simple method eliminates or corrects errors of orientation when driving, and/or screwing and/or drilling.

According to the invention this problem is solved by the device according to paragraph 1 of the claims.

This device differs from the known devices the fact that the place of his swivel is made with an option of displacement relative to the drive head knock, and/or svertyvayuschego, and/or a drilling device, at least in the first direction perpendicular to the longitudinal axis of the Foundation device/pipe/excavation drill. Due to this boom, or more specifically, the hinge connection arrows located between the shaft and the drive head, buys the freedom of displacement, at least in the first direction from the axis of the Foundation device/pipe/auger, not creating lateral load and thereby not Perekareva them. Therefore, compensation is not achieved in the boom and not due to a change in its length, and device penetration, more precisely at any site between the hinge connection of the boom and the drive head.

Compared with solutions of prior art here with varying benefits. To compensate for the errors do not require conversion of construction machinery or her arrows, and you no longer want to use is completely insufficient funds management of the construction machine. Compensation is provided already present additional part of the unit of penetration, its suspension, with relatively minor refurbishment. This conversion is relatively simple, for example, compared with the length adjustment known hydraulic drilling device. But first offset if the such should operate and be managed, can occur through (hydraulic) actuators and their control devices provided for already in the modern construction machines and intended for auxiliary tools. For example, the management of the offset may be performed by the operator of the easiest manual way.

In another embodiment, the hinge connection may be made with the possibility of misalignment of drive heads, and in a second direction, which is perpendicular to the first. In this case, can be compensated not only errors of orientation in the first direction, but also errors in the second direction, resulting in possible to simultaneously compensate for all overlay errors in both directions.

Since the main source of error in orientation is moving seats swivel in the longitudinal direction of the arrows, the first direction for the free mobility is preferably a longitudinal direction of the arrows.

Particularly structurally simple and compact mobility is achieved in the case when the suspension, known devices for screwing, made in the form of a universal joint and, otherwise than in the prior art, at least the first hinge axis extended to ensure mobility in the first direction such that the first and the second elements of the universal joint are movable relative to each other along the axis of the hinge.

In this case, the first hinge axis is preferably oriented in the first direction, in a doubtful case in the longitudinal direction of the arrows.

However, a more perfect additional adjustment is provided in the case, when the second axis of the universal joint is lengthened so that the second and third elements of the universal joint are arranged on it with the possibility of displacement relative to each other. In this case, the imposition of both types of mobility can be compensated for any deviation seat swivel from the axis of the Foundation device/pipe/auger, in any direction.

If we are talking only about the mobility seat swivel, which is necessary to ensure that the arrow did not sideways during their movements, the Foundation device/pipe/auger, it is sufficient free mobility of universal joints on axes. The presence of the actuator in this case is not necessary.

Of course, the desired smooth operation of the hinge in severe operating conditions cannot always be ensured, resulting in already for this reason it is optimal to provide the appropriate drive to move. In addition, this actuator can be used for other purposes. For example, it will allow for active correction of the health is ovci, the installation of the device penetration in other than the vertical direction or the installation, which will allow you to connect laying the Foundation device/pipe/auger into position.

In this case, the actuation may be provided by already contained in modern construction machines, in most cases, the hydraulic drives for additional mechanisms and, consequently, no structural changes building machine or its arrows.

The actuator or actuators can be operated manually using the associated control devices.

Regulation or automatic control may be effected in the most simple case, a switch to the inclined position.

To show the operator the current angular position of the device penetration in relation to the Foundation device/pipe/borax, on the device structures may be provided inclinometer.

The device structures may have at least one limitation on the range of rotation, which allows you to bring the device into the corresponding inclined position to attach lying on the ground the Foundation device/pipe/auger essentially in a horizontal position or in a position deviating from the vertical at depth./p>

Without significant conversion device can be an alternative or cumulatively executed for driving and/or screwing the Foundation of fixtures or pipes, and/or for drilling in soil and/or rocks. In the case of execution for drilling in the ground, the device is designed to move earth mass.
