Description

  The present invention mainly relates to a civil engineering machine such as a hydraulic excavator used for processing steep slopes.

  Conventionally, for example, when a slope is formed by processing a steep slope, a civil engineering machine such as a hydraulic excavator, a bulldozer, or a backhoe that is driven by a remote control operation is used in order to avoid danger of workers. ing.

This civil engineering machine is usually composed of a traveling body such as a caterpillar that is self-propelled on an inclined ground, and an operation table that is rotatably provided immediately above the traveling body, and in order to prevent sliding off from the inclined ground. A winch device is fixed to each of the left and right rear portions (or front portions) of the operation console. Then, each winch device and the anchor driven to the right and left sides of the inclined surface P are connected by wires, for example, when moving to the left, the left wire is wound by the left winch device. At the same time, the civil engineering machine is caused to self-propelled in the left direction while releasing the right wire with the right winch device (see, for example, Patent Document 1).
Japanese Patent Publication No. 7-33682

However, these conventional civil engineering machines have the following problems.
(A) Since the winch device is fixed to the rear portion of the operation table, the position of the wire connected to the winch device cannot be moved. Therefore, when the operation table is rotated, the operation table is easily entangled. Therefore, the rotation of the operation table is hindered, and the civil engineering machine cannot be moved smoothly.
(B) Since two winch devices and two wires are used, it is necessary to perform separate operations synchronously with separate devices such as releasing one wire while winding the other wire. Is troublesome. Moreover, unless the operation is performed in synchronization, the civil engineering machine cannot be moved smoothly.
(C) Since two winch devices are required, the civil engineering machine becomes larger and heavier than necessary, and the manufacturing cost increases.

  The present invention was devised in view of these problems, and it is possible to provide a civil engineering machine for sloping terrain that can easily and smoothly move in the left-right direction, can be reduced in size and weight, and is inexpensive to manufacture. Let it be an issue.

  This will be described with reference to FIGS. The civil engineering machine 1 for sloping ground according to claim 1 is a civil engineering machine that is operated by a remote control operation mainly for processing steep sloping ground, and a traveling body 20 that self-propels on the sloping ground and directly above it. A disk body 30 is provided in a horizontal direction with respect to the operation table 10 between the operation table 10 and the operation table 10 so as to be freely rotatable. The disk body 30 moves along the peripheral end portion of the disk body 30. A freely rotating body 40 is provided, and a drum body 50 that is rotatable in the horizontal direction with respect to the rotating body 40 is provided on the rotating body 40.

  The wire body 51 is wound around the drum body 50 so that the wire 51 cannot slide, and one end of the wire 51 is fixed to the first anchor F driven into the high place of the inclined land. The other end is fixed to the second anchor S driven in the left-right direction of the first anchor F.

  The civil engineering machine 1 for sloping ground according to claim 2 is a civil engineering machine that is operated by a remote control operation mainly for processing steep sloping ground, and a traveling body 20 that self-propels on the sloping ground and directly above it. A disk body 30 is provided in a horizontal direction with respect to the operation table 10 between the operation table 10 and the operation table 10 so as to be freely rotatable. The disk body 30 moves along the peripheral end portion of the disk body 30. A freely rotating body 40 is provided, and a drum body 50 that is rotatable in the horizontal direction with respect to the rotating body 40 is provided on the rotating body 40.

  Further, the peripheral body 40 is assembled with a base end portion 41 provided at a peripheral end portion of the disc body 30 and a base end portion 41 so as to be rotatable in the vertical direction, and a storage portion for storing the drum body 50. 43.

  The wire body 51 is wound around the drum body 50 so that the wire 51 cannot slide, and one end of the wire 51 is fixed to the first anchor F driven into the high place of the inclined land. The other end is fixed to the second anchor S driven in the left-right direction of the first anchor F.

  The civil engineering machine 1 for sloping lands according to claim 1 is provided with a movable body 40 that is movable along the peripheral end portion at a peripheral end portion of a disc body 30 provided in a portion between the operation table 10 and the traveling body 20. The drum body 50 is provided with a rotatable drum body 50. The wire body 51 is wound around the drum body 50 by a number of windings incapable of sliding. Since the other end of the wire 51 is fixed to the second anchor S that is driven in the left-right direction of the first anchor F, the civil engineering machine 1 moves the inclined ground in the left-right direction. Can be moved easily and smoothly. Further, the size and weight can be reduced, and the manufacturing cost can be reduced.

  That is, when the operation table 10 is rotated while the wire 51 is pulled, the moving body 40 is moved along the peripheral end portion of the disk body 30 by the pulling force, and is always positioned at the top of the civil engineering machine 1. . Therefore, the wire 51 is not entangled with the operation table 10, and the operation table 10 is smoothly rotated and the civil engineering machine 1 is moved smoothly.

  Further, when the drum body 50 is rotated with one end of the wire 51 fixed to the first anchor F and the other end fixed to the second anchor S, for example, one end side of the wire 51 is wound up, The other end side is released, whereby the civil engineering machine 1 moves to one end side. Since this movement is performed by rotating one drum body 50, it is not necessary to operate the two winch devices synchronously as in the prior art. Therefore, the operation is easy, and when the operations are not performed synchronously, it is possible to prevent a situation in which the civil engineering machine 1 is not smoothly operated. Therefore, the civil engineering machine 1 can always be moved smoothly.

  In addition, since the wire 51 is wound around the drum body 50 so as not to be slidable, when the drum body 50 is rotated, the wire 51 is wound and released without slipping on the drum body 50. The civil engineering machine 1 can move smoothly in the left-right direction (horizontal direction).

  Moreover, since this civil engineering machine 1 for sloping land uses the one drum body 50, compared with what provided two winch apparatuses like the prior art, the said civil engineering machine 1 can be reduced in size. In addition, the manufacturing cost can be kept low.

  The civil engineering machine 1 for sloping lands according to claim 2 can be moved easily and smoothly on sloping lands in the left-right direction as well as the invention according to claim 1, and can be reduced in size and weight. Costs can be kept low.

  Further, the rotating body 40 is assembled with a base end portion 41 provided at a peripheral end portion of the disk body 30 and a storage portion 43 that accommodates the base end portion 41 so as to be rotatable in the vertical direction and stores the drum body 50. Since it comprises, the said civil engineering machine 1 can be moved further smoothly.

  That is, when the inclination angle of the civil engineering machine 1 on the inclined land is different from the inclination angle of the wire 51 connected to the civil engineering machine 1, the accommodating portion 43 corresponds to the inclination angle of the wire 51 by the tensile force of the wire 51. Rotate. Therefore, since no extra lifting force or pressing force acts on the civil engineering machine 1 from the wire 51, the civil engineering machine 1 can move more smoothly in the left-right direction.

  An embodiment of a civil engineering machine 1 for sloping lands according to the present invention is shown in FIGS. This is a civil engineering machine (hydraulic excavator) 1 that is operated by remote control operation to process a steep slope, and is provided on a traveling body (caterpillar) 20 that self-travels on the slope and is rotatably provided immediately above. The operation console 10 is provided. A disc body 30 is provided between the traveling body 20 and the operation console 10. The disk body 30 is provided in the horizontal direction with respect to the operation console 10 and is fixed to the operation console 10. In addition, a circumferentially movable body 40 that is movable along the circumferential end portion is provided at the circumferential end portion of the disk body 30. Furthermore, a drum body 50 that is rotatable in the horizontal direction with respect to the circumferential body 40 is provided on the circumferential body 40. The drum body 50 is remotely driven by a hydraulic motor 52 integrally attached thereto.

  And the wire 51 is wound around this drum body 50 by the number of windings which cannot be slid, and the one end of the said wire 51 is being fixed to the 1st anchor F driven into the high place of the sloping ground. Further, the other end of the wire 51 is fixed to the second anchor S driven in the right direction of the first anchor F, also at the height of the inclined ground. The number of unslidable turns varies depending on the weight of the civil engineering machine 1 and the type of the wire 51, but is usually several times to about 5 to 6 times.

  For example, in order to form a slope on an inclined land using this civil engineering machine 1, it is performed as follows. First, the first anchor F and the second anchor S are driven into the high place of the slope, and one end of the wire 51 wound around the drum body 50 of the civil engineering machine 1 is fixed to the first anchor F, and the other end is fixed to the second anchor. Fix to S.

  In this state, the drum body 50 is rotated in a predetermined direction in order to move in the left-right (horizontal) direction while processing the slope. By this rotation, for example, one end side of the wire 51 is wound up, and at the same time the other end side is released, so that the civil engineering machine 1 can run without sliding down to the left. Further, in order to move in the right direction, the drum body 50 is rotated in the reverse direction.

  In addition, when processing the sloping ground or moving in the left-right direction, the operation console 10 is rotated as necessary. At this time, the rotating body 40 is rotated around the disk body 30 by the tensile force of the wire 51. Since it moves along the end and is always located at the top of the civil engineering machine 1, it does not get tangled with the operation console 10. Therefore, the operation table 10 can be rotated and the civil engineering machine 1 can be moved smoothly.

  Moreover, since the civil engineering machine 1 is moved by rotating one drum body 50, it is easy to operate and can be moved smoothly.

  In addition, since the wire 51 is wound around the drum body 50 so that the wire 51 cannot slide, the problem that the wire 51 does not slide and does not move when the drum body 50 is rotated does not occur. 1 can move smoothly in the left-right direction.

  Moreover, since this civil engineering machine 1 for sloping lands uses one drum body 50, the civil engineering machine 1 can be miniaturized, and the manufacturing cost can be kept low.

  In addition, in order to complete the processing in the left-right direction and move to a low place, one end side or the other end side (or both) of the wire 51 is released by the winch mechanism W or the like and positioned on the inclined surface P. The length of the wire 51 is extended. Conversely, in order to move to a high place, the wire 51 is shortened by winding with a winch mechanism W or the like. By repeating these steps, the entire top, bottom, left and right of the inclined surface P can be processed by the civil engineering machine 1.

  In addition, as shown in FIG. 3 and FIG. 4, the earth-moving civil engineering machine 1 according to the present invention is configured so that the rotating body 40 is connected to the base end portion 41 provided at the peripheral end portion of the disc body 30 and the base end portion 41. The shaft bar 44 can be assembled to be rotatable in the vertical direction, and can be constituted by a storage portion 43 for storing the drum body 50. Note that a guide rod 45 that guides the wire 51 is rotatably provided in the peripheral portion 40.

  Accordingly, when the inclination angle of the civil engineering machine 1 on the inclined land is different from the inclination angle of the wire 51 connected to the civil engineering machine 1, the storage unit 43 corresponds to the inclination angle of the wire 51 by the tensile force of the wire 51. Therefore, an excessive lifting force or pushing force from the wire 51 does not act on the civil engineering machine 1. Therefore, the civil engineering machine 1 can be moved more smoothly in the left-right direction.

  In the above-described embodiment, the protrusions 31 protruding upward and downward are formed on the peripheral end of the disk body 30, and the protrusions 31 are provided on the peripheral body 40 so as to be rotatable on both the left and right surfaces and the front and rear surfaces. The support roller 42 is rolled to smoothly move the peripheral moving body 40.

  Moreover, although the civil engineering machine 1 in the said embodiment is used as the hydraulic excavator, this invention is not limited to this, For example, other civil engineering machines 1, such as a bulldozer and a backhoe, are included. Moreover, the traveling body 20 is not limited to a caterpillar and includes other traveling mechanisms such as wheels.
