    Field of the invention
    The invention relates to a piling device for inserting piles in a subsoil according to the preamble of claim 1 and a method for inserting piles in a subsoil according to claim 12.
    State of the art
    To reinforce the soil piles must be rammed into the ground in construction. This activity is called pile or pilot foundation. As devices on the one hand freireitende ramming or vibration devices are used, such as a high-speed hammer, which may be attached to a hydraulic excavator as a carrier device. Freireitende devices have the disadvantage that the percussion hammer is not out and therefore can only drive the piles with a limited accuracy.
    In order to overcome this disadvantage so-called brokers or carriages are known in construction. A rammer is guided by the broker. Although these devices increase the accuracy, but are very expensive due to the complex guide device.
    Object of the invention
    From the disadvantages of the described prior art, the present invention initiates the task of further developing a generic piling apparatus for inserting piles, which is simple and therefore inexpensive to produce and still has a high degree of accuracy in driving the piles.
    description
    The pile driver for inserting piles in a ground comprises a working device with a housing. The implement may be, for example, a high-speed hammer. The housing is linearly guided on a linear guide in order to drive piles straight into the ground.
    The solution of the problem is achieved with a piling device characterized in that the housing is in direct contact with the linear guide and in the direction of its longitudinal extent free van further connections or drives between housing and linear guide slides on the linear guide. The piling device can therefore be carried out freely by a broker. The invention makes use of the mobility of a digger arm. As a further compounds or drives in particular pneumatic or hydraulic actuators are to be understood, which can move the housing relative to the linear guide. However, such mostly mechanical connections or drives are not necessary because the housing slides due to gravity along the linear guide down. The fact that the excavator arm can push the linear guide relative to the housing again and again down when the upper end of the housing abuts the linear guide, can be dispensed with meter-long inflexible guide devices such as brokers or carriages.
    It has proven to be advantageous if the linear guide encloses the circumference of the housing at least partially. The linear guide may, for example, have the shape of a sleeve. The cuff essentially has the cross-sectional shape of the housing. The cuff is sized so that the housing can slide in it and does not wobble or jam.
    The invention is preferably characterized by the fact that the linear guide is a bearing housing. As a result, it is possible to arrange bearings on the linear guide, which allow an exact and at the same time friction-minimized guidance.
    As appropriate, it has been proven when the bearing housing is provided with sliding bodies, which rest on the housing of the implement. As a result, the implement is performed accurately and smoothly in the linear guide.
    Conveniently, the distance of the slider is adjustable relative to the housing of the implement. As a result, the slider can be precisely adjusted, which allows the housing runs smoothly in the linear guide, without wobbling or jamming. Also, the bearings can be readjusted if they wear out.
    With preference, the distance of the Gleitköper to the housing with built-in housing in the linear guide is adjustable. As a result, the implement must not be removed from the linear guide for the adjustment of the slider and the setting is always easily accessible.
    It proves to be advantageous if the slider are made of a plastic, which has good sliding properties against the housing surface. For example, Teflon is conceivable as a plastic because it has good sliding properties over many materials and durable.
    The invention is also preferably characterized in that the connecting element is part of a quick coupling for fixing to an excavator and is firmly connected to the linear guide. The piling device can therefore be quickly connected to the free end of a digger arm and released from it. The excavator arm then takes over the task of re-adjusting the linear guide repeatedly until the entire pile length is inserted into the ground.
    In a particularly preferred embodiment, the device comprises a position detection, with the aid of which the linear guide can be positioned in an exact preselected position. As a result, the linear guide can be guided by means of the excavator arm in an exact working position, before starting with the insertion of the piles. Also, the linear guide can be readjusted during insertion repeatedly.
    The invention is also preferably characterized in that the linear guide has a height of less than one meter. At a minimum height, which corresponds to at least the length of a pile can therefore be dispensed with. Makers and carriages, which have lengths of five meters or more, in order to position the implement over a not yet driven pile, are therefore not necessary. Brokers are expensive and bulky due to their length and it is a great advantage to be able to do without these guiding devices.
    Another aspect of the invention relates to a linear guide alone. The linear guide can namely be used to hold a commercial, already existing in the equipment park implement, which is normally mounted directly on an excavator.
    Yet another aspect of the invention relates to a method for installing piles in a ground. The method is characterized in that at the beginning of the Pfahleinsetzens connected to an excavator arm of an excavator linear guide is positioned at the bottom of a run on the linear guide housing a working device on the position of the excavator. Then, during the poppet setting, the housing of the implement slides along the linear guide until the upper end of the housing abuts the linear guide. The linear guide is moved in a third step by moving the excavator arm back to the lower end of the housing. The reciprocation of the linear guide along the housing is continued until the desired pile length is inserted into the ground. The length of the excavator arm is therefore used to position the implement over a pile to be driven. The length of the housing of the implement is used as part of a linear guide
    Further advantages and features will become apparent from the following description of an embodiment of the invention with reference to the schematic representations. It shows in not to scale representation:<Tb> FIG. 1: <SEP> a side view of a piling device and<Tb> FIG. 2: <SEP> an axonometric view of the pile driver of FIG. 2.
    In Figs. 1 and 2 an embodiment of an inventive piling device is shown, which is generally designated by the reference numeral 11. The piling device is used for ramming piles in a ground for reinforcing the soil. The piling device 11 comprises a working device which, in the embodiment shown, is a rapid impact hammer 13. The quick hammer 13 is commercially available and can be coupled by means of a part of a quick coupling which is flanged to the flange to an excavator.
    The rapid hammer 13 comprises a housing 17 and a protruding from the lower end of his tool 18. In the embodiment shown, the tool 18 is a fast-hitting hammer with an attached bell jig 19. The bell jaw 19 is aufurammenden to the free end of a Pile put on. If the quick hammer 13 is coupled directly to the excavator, there is no linear guide, which is preferably oriented vertically to the ground, available. The orientation of the rammed piles is therefore relatively inaccurate.
    The inventive piling device 11 comprises a linear guide 21 which is fixedly connected to a part of a quick coupling 23. For example, the parts can be screwed together. The part 23 can be mechanically connected to the second part of a quick coupling, which is fastened to the free end of an excavator arm. The ram hung in front of the rope 11 can be quickly connected to the excavator arm with the quick coupling.
    The linear guide 21 is in its simplest embodiment, a top and bottom open shell 25 of a cuboid. After bearings are arranged on the inside of the cuboid casing, the linear guide can also be referred to as a bearing housing 21. The housing of the quick hammer hammers slides on the inside of the cuboid shell 25. There is no need to use a special quick hammer 13, but it can be any fast hammer used, which would actually be intended to be coupled directly to a digger arm. In order to keep the sliding friction as low as possible, plastic bearings are arranged between the inside of the cuboid casing 25 and the housing 17. Preferably, the plastic bearings can be adjusted from the outside by means of screws 27. As a result, the guide is accurate and the sliding friction still low. It is understood that the plastic of the bearing is a plastic, which has the lowest possible sliding friction with respect to the housing surface. This can be for example Teflon. The housing 17 is in direct contact with the linear guide 21 and slides in the direction of its longitudinal extension free of further particular mechanical connections or drives between housing 17 and linear guide 21 on the linear guide 21. The device is therefore very reliable, since no additional connections or drives between the housing 17 and the linear guide are present, which could go broke or could jam.
    A height of the linear guide of less than one meter is sufficient for an accurate guidance, since the linear guide can be adjusted again and again by adjusting the excavator. The exact operation is described below.
    The inventive piling device 11 requires no leader, no carriage or any other guide mast, which, caused by their length of 10 meters and more, are expensive and bulky. In particular, the arrival and removal of these guide devices of the prior art is very expensive.
    The pile driving a pile is carried out in the following steps: First, a stake is placed at the point to be excavated ground. The prefixing of the pile can be done by drilling a hole in the subsoil in advance. At the beginning of the linear guide 21, for example, by means of a position detection in. An exact desired position. It is conceivable that coordinates are given, which correspond to a selected orientation of the pile to be eingurammenden and the linear guide automatically adjusts accordingly. At the beginning of the piling operation, the linear guide 21 is to be arranged at the lower end of the housing 17 and brought into an exact orientation by means of the position detection. By adjusting the excavator arm, any three-dimensional adjustment of the linear guide can be achieved. If the linear guide is in its exact position, the percussion hammer 13 is actuated until the pile has been driven into the foundation ground until the upper end of the housing 17 abuts against the linear guide. Now, the linear guide 21 is to move back by pressing the excavator arm down until it has reached the lower end of the housing 17. Now the rapid hammer 13 can be operated again until the housing 17 along the linear guide 21 has moved completely down. In this way of moving the linear guide back and forth; Not only can a pile be driven in but also any number of ductile piles connected by sockets.
