Turning control after stopping turn of the upper turning machine body 1b under this condition, may place the lower running machine body 1a in turning operation by means of a turning allowing mechanism.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a track working machine used, for example, for repairing railroad tracks and their surroundings.

[0002]

2. Description of the Related Art Conventionally, as an orbital working machine of this kind, an attachment such as a shovel excavation mechanism is provided on a working machine body,
It is known that this working machine is provided with a crawler track for traveling on the ground and a wheel for detachable rail running.

For example, during excavator excavation or sleeper replacement work, the crawler belt is placed on the ground on the side of two rails on both sides with the wheels removed from the work machine, and in this state, for example, excavation work or railroad track bed replacement. When performing work, etc., or traveling on a rail to move to another place, attach the wheel to the work machine, put this wheel on the rail, lift the crawler track off the ground, and drive the wheel in this state It is configured to run on rails.

[0004]

However, in the case of the above-mentioned conventional structure, it is difficult to attach and detach the wheels to and from the working machine body,
The workability is reduced by that much, and because the track work is usually done between trains passing, if the evacuation time to the side of the track takes a lot of time, the safety of emergency will be reduced accordingly. Have

The circular mounting member 3 is provided on the lower surface of the table by the turning permission mechanism 30.
1 is arranged so as to be capable of turning.

The turning permission mechanism 30 is provided in the mounting member 3 described above.
1, a rotation shaft 32 is provided upright, the rotation shaft 32 is inserted through the center of the mounting member 24, a fastening member 33 is fitted on the rotation shaft 32, and the mounting member 24 and the mounting member are mounted. A plurality of bearing members 34 are annularly interposed between the mounting member 31 and the mounting member 31, and the mounting member 31 can be rotated with respect to the mounting member 24.

Since this embodiment has the above structure, the rocking member 19 is rocked upward about the upper pivot shaft 20 by extending the rod 21a of the vertically moving cylinder 21 as shown in FIG. And the working machine body 1 is lowered by this to place the crawler belt 16 on the ground S on the side of the two rails W on both sides, and in this state, the crane mechanism 12 can perform the crane work, and the place When traveling on the rail W for movement or the like, the swing member 19 is swung downward about the upper pivot shaft 20 by reducing the rod 21a of the vertical movement cylinder 21 as shown in FIGS. 17 is lowered to be placed on the rail W, whereby the working machine body 1 is lifted to separate the crawler belt 16 from the ground, and in this state, the wheels 17 can be driven to run on the rail. Figure 5 in the case of escape trajectory laterally from, as shown in FIG. 7, the rod portion 27 of the connecting and disconnecting the cylinder 27
a is extended to lower the mounting member 24, and the rod 21a of the vertical movement cylinder 21 is extended to swing the swinging member 19 upward about the upper pivot shaft 20 to move the wheel 17 to the raised position. Then, the working machine body 1 is lowered to bring the mounting member 31 into contact with the rail W, and the rod portion 27a of the contacting / separating cylinder 27 is further extended to raise the working machine body 1 and, for example, an operator in this floating state. When the upper swing body 1b is rotated by the swing operation mechanism including a gear mechanism (not shown) in the driver's seat while the upper swing body 1b is held by the crane hook 13, the upper swing body 1b is not rotated.
Instead of turning, the lower traveling vehicle body 1a pivots about the rotating shaft 1c, the rotation permitting mechanism 30 allows the lower traveling vehicle body 1a to rotate with the mounting member 31 fixed in position, and the bearing body 34 serves as the lower traveling vehicle body. Make the turning of 1a smooth,
Therefore, for example, approximately 9 from the solid line state to the imaginary line state in FIG.
The lower revolving machine body 1a is revolved at 0 degrees, and the rod 27a of the contacting / separating cylinder 27 is contracted to lower the work machine body 1 in the state after this revolving, and the crawler belt 16 has two rails W on both sides.
It is possible to escape by placing it on the top and driving the crawler belt 16, and it is possible to reduce the escape evacuation time to the side of the track in an emergency and improve the safety of work.

In this case, at the time of the minimum contraction operation of the vertical movement cylinder 21, the center of the axle 17a of the wheel 17 is separated from the upper pivot shaft 20 by a distance L, for example, and the fuselage side pivot shaft 22 is provided.
Since it is arranged on the side, it is possible to prevent the upward swinging motion of the swinging member 19 due to the weight of the working machine body 1 or the like. Therefore, for example, even if there is an unavoidable oil leak, this is caused. It is possible to prevent the work machine body 1 from falling, improve the safety during running on the rail, and perform the downward swinging motion of the swinging member 19 because the vertically moving cylinder 21 is in the minimum contracting motion state. It is designed to prevent it.

The present invention is not limited to the above embodiment, and the turning permission mechanism 30 is designed by appropriately changing it, for example.

[0016]

As described above, according to the present invention, the lower traveling machine body is provided with the mounting member which can be moved up and down by the contacting / separating cylinder, and the mounting member which can be mounted on the rail is mounted on the mounting member by the turning permission mechanism. Since it is arranged so that it can rotate, when the rail escapes, the mounting member is lowered by the contact / separation cylinder, the mounting member is placed on the rail to float the work machine, and in this state the upper swing If the turning operation is performed with the machine body stopped, the lower traveling machine body will rotate due to the rotation allowance mechanism.Therefore, the lower machine body will be rotated in the escape direction, the wheels will be raised, and the track will be driven. The escape time can be shortened and the safety of work can be improved.

As described above, the intended purpose can be sufficiently achieved.
