Disclosure of inventions

Object of the invention is the creation of a working construction machine, in which the cable winch can be rotated particularly economical and flexible way.

In accordance with the invention the solution of this problem is achieved in the work of the construction machine according to paragraph 1 of the claims. Preferred embodiments of the invention set forth in dependent clauses.

Working construction machine according to the invention is characterized in that the first pivot pin is arranged to detach to release the first axis of rotation and at least one second pivot pin can be installed on the cable winch for the formation of a second axis of rotation spaced from the first axis of rotation, and the cable winch is made with a possibility of rotation around the second axis of rotation by means of cylinder rotation.

The first basic idea of the invention is to create a rope winch, which can be rotated about two different axes of rotation. Two axes of rotation are separated from each other, i.e. are not along the same line. Preferably the pivot axis are transverse to each other and may also intersect at a point.

Organization of at least two different axes of rotation which allows you to rotate the cable winch in different directions. Cable winch, which, thus, can be rotated, at least around two axes, may, for example, by rotation around the first axis of rotation to be rotated between the front and rear position, and by rotation around the second axis of rotation to be rotated between the two positions of the side slope.

The second basic idea of the invention is to provide for the establishment of two defined axes of rotation. For this purpose, the cable winch mounted on the host vehicle by using at least two razmykaetsya bearing hinges. For education razmykaetsya bearing hinges each axis of rotation includes at least one pivot pin, is made adjustable between a locking position (circuit) and open position or the release position. In the position of the circuit using the adjustable finger creates a pivot point, which can be released (opened) by detaching or removing the hinge finger.

When both articulated fingers are in the position circuit, preferably the cable winch fastened them tightly and cannot be rotated. When removing one of the pivot pins is activated corresponding to the other axis of rotation, so that the cable winch can be rotated around this axis of rotation. So, can the percentage winch can be turned on or around the first axis of rotation, or around the second axis of rotation, depending on which pivot pin is located in the state of the circuit or disconnected.

According to the invention, the working of the construction machine includes a cylinder rotation to rotate the cable winch selectively around the first rotation axis or the second axis of rotation. Depending on which pivot pin is inserted or removed, when the drive cylinder of rotation of the cable winch is rotated around the first rotation axis or around the second axis of rotation. Thus, depending on the position of the pivot pins of the cable winch can be rotated around the first or second axis of rotation. If the first pivot pin is installed, and the second pivot pin is disconnected, when the actuation of the cylinder of rotation of the cable winch is rotated around the first axis of rotation. If the second pivot pin is installed, and the first pivot pin is disconnected, when the actuation of the cylinder of rotation of the cable winch is rotated around the second rotation axis.

Accordingly, following the basic idea of the invention is to provide a single cylinder rotation made with the possibility of rotation of the cable winch around various defined (specified) axes of rotation. For this purpose, the cylinder rotation, preferably mouth is attached with a ball joint on the host vehicle and/or on the cable winch.

In the preferred embodiment of the invention the cable winch by rotation around the first axis of rotation can be rotated between a working position and a transport position. Thus the axis of rotation of the cable winch in the transport position, preferably is lower than in the working position, so that by turning the cable winch in the transport position can be reduced altitude envelope of the working of the construction machine. In the working position of the cable winch can be, in particular, in the upper and/or the front bearing area of the vehicle, and in the transport position in the bottom and/or rear region.

Preferably the first axis of rotation is parallel to the axis of rotation of the cable winch. Due to this, the cable winch can be optimally rotated between the working and transport positions. Preferably the axis of rotation of the cable winch runs transversely to the longitudinal direction of the carrier vehicle.

In the following preferred embodiment of the invention the second axis of rotation passes transversely to the axis of rotation of the cable winch, so that the rotation axis can be tilted by turning the cable winch around the second axis of rotation. This allows you to tilt the cable winch to the side to change the angle of the entrance of the rope on the winch. Preferably, the rope is sent by the sending unit, located on the mast. Due to the lateral inclination of the cable winch can be improved styling with the winding of the rope and thereby reduced the load on the rope.

The flexibility of use of the work of the construction machine can be increased due to the fact that the mast can be tilted in a transverse lateral direction relative to the carrier vehicle. In this case, the cable winch can be rotated around the second axis of rotation in accordance with the inclination of the mast and also tilted to one side, to suitably adjust the entrance of the wire rope on the winch.

To rotate the cable winch preferably the cylinder rotation is the first point of the hinge mounting on the host vehicle and the second point of the hinge mounting on the cable winch. Preferably the cylinder rotation includes a housing cylinder, which is the first point of the articulation, and movably mounted in the cylinder body, the piston with the piston rod, which is the second point of hinged attachment.

In order to allow selective rotation of the cable winch using the same cylinder rotation around the first or second axis of rotation, preferably the first point of the articulation in the work floor the position of the cable winch is located under the cable winch.

Particularly in relation to side tilt cable winch around the second axis of rotation preferably, the second hinge point of attachment is located in the lateral direction of the cable winch offset relative to the middle axis of rotation of the cable winch. Preferably, the second hinge point of attachment is located at the distance from the first axis of rotation and the second axis of rotation, so that rotation of the cable winch around both axes of rotation are possible without the need for articulated mounting of cylinder rotation to the cable winch at various points.

Particularly in relation to the rotation of the cable winch around the first axis of rotation preferably, the second hinge point of attachment is located in the lateral direction of the cable winch between the two pivot joints, which form the first axis of rotation of the cable winch. Due to the articulated mounting of cylinder rotation between the support hinges or between two longitudinal walls is achieved an advantageous application of force during the rotation around the first rotation axis.

In principle, it is possible to manually enter or remove pivot pins. However, to automate the creation or formation of the first and/or second axis of rotation, it is preferable that was provided, at least one actuating cylinder, which may be the mouth is attached and/or detached first pivot pin and/or the second pivot pin. For this purpose, the actuating cylinder is preferably connected with the respective articulated fingers, to install and/or remove them and thereby to close and/or rasmijoti corresponding bearing hinge.

To establish certain axes of rotation preferably each axis of rotation is formed by at least two pivot points. The first datum for each axis of rotation contains the first or second pivot pin. Second support point is formed by another hinge.

Best bearing rope winch is due to the fact that there is General support hinge to rotate around a first axis of rotation and to rotate around a second axis of rotation. The first rotation axis preferably passes through a common supporting hinge and the first pivot pin and the second axis of rotation passes through the common pivot and the second pivot pin. Due to this, each active axis of rotation can be arranged by installing or detaching the only one hinge finger for each axis of rotation.

To rotate around the axes of rotation located transversely to each other, preferably a common supporting hinge is made in the form of a support hinge with the possibility of movement along three axes. It can be, for example, a ball joint.

Particularly preferably the total bearing hinge where the hinge pin with a ball head or a hemisphere. Due to the articulated fingers with a ball head or a hemisphere creates a structurally simple hinge with the freedom of the spatial turn.

In the following preferred embodiment, the common reference hinge and/or at least one of the detachable anchor hinges may allow in addition to the rotary movement of the progressive movement, to provide selective rotation of the cable winch around the first or second axis of rotation.

First razlichimy bearing hinge 52 includes pivot pin 62, which can be inserted to establish a swivel. To do this, support the vehicle 12 has a support plate with a support ring 76 and the frame 22 has a support bar 78. The first pivot pin 62 may be inserted in the bearing lugs 76, 78. Accordingly the second razlichimy bearing hinge 54 includes a second pivot pin 64, which can be entered in the appropriate anchor lugs 76, 78 on the host vehicle 12 and the frame 22 of the winch. Preferably the first support hinge 52 is rotatable hinge with a single axis of rotation. The second support hinge 54 may be tilting hinge with one axis of rotation or swivel joint with two axes of rotation, and may include, for example, pivot pin with hemisphere.

General support hinge 56 includes a third pivot pin 66, which is preferably made with a ball part, and may be called articulated finger with two axes of rotation. This pivot pin 66 spatial rotation provides the ability to rotate the cable winch 20 around both axes 28, 30. General support hinge 56 and/or the second break is th anchor hinge 54 can also prevent translational motion.

Anchor hinge 56 forms a front of the supporting region 70 of the cable winch 20. Bearing hinges 52, 54 form a back support region 72. All bearing hinges 52, 54 and 56 form the fulcrum of the cable winch 20.

In addition, on one anchor point of the cable winch 20 can be provided with a locking device 58, for example, with a locking finger for locking the cable winch 20 in the working position. Bearing hinges 52, 54, 56 and the locking device 58 is preferably located in the corners of the rectangle.
