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 a track working machine of this type, there is known a work machine having an excavator excavating mechanism provided with a track for track traveling and detachable wheels for running on a track. ing.

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, the crane work cannot be performed despite the heavy load work in the track work, which is often inconvenient for the shovel, and the wheel to the work machine body is often inconvenient. It is difficult to put on and take off the rails, and the workability is reduced accordingly. Furthermore, because the track work is usually done between train passages, it takes a lot of evacuation and escape time to the side of the track, so the safety in an emergency Has the disadvantage of being low.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to solve such an inconvenience, and the gist thereof is to provide a working machine body with a track for running on the ground and wheels for running on a rail. A crane mechanism is arranged on the working machine body, and a rocking member is pivotally mounted at a front and rear position in the traveling direction of the working machine body so as to be vertically rockable, and the wheels are arranged on the rocking member. An orbiting work machine characterized in that a vertical movement cylinder is pivotally mounted between the rocking member and the rocking member.

[0006]

When the rocking member is lifted by the vertical movement cylinder, the wheels are raised, the work machine is lowered, and the track is grounded. When traveling on a rail, the vertical movement cylinder is used for rocking. When the member is lowered, the wheel descends, the wheel is placed on the rail, the working machine surface floats, and the crawler belt floats away from the ground.In this state, the wheel is driven and the track travels. Crane work will be performed by the crane mechanism while it is grounded.

A main boom 4 which can be lifted and lowered around a support shaft 3a by a hydraulic cylinder 3 is provided on the upper part of the telescopic boom 5, and a telescopic boom 5 is provided in the main boom 4 by a built-in hydraulic cylinder (not shown) so as to be telescopically movable. A crane mechanism 6 is provided at the tip of the.

In this case, in the crane mechanism 6, the hydraulic winch 7 is arranged on the column 2, the guide sheaves 8 and 9 are provided at the tip end of the telescopic boom 5, and the hook sheave 11 is arranged on the lifting frame 10. , Hydraulic winch 7 to sheave 8.9
・ Steel rope 12 is hung on 11 and its tip is telescopic boom 5
And attach the crane hook 13 to the lifting frame 10,
The crane hook 13 is vertically moved by the hoisting and lowering operation of the hydraulic winch 7.

Reference numeral 14 denotes a support member, which is a lower traveling vehicle body 1.
The track body 1 is disposed on both left and right sides of a
5, a hydraulic motor (not shown) is arranged on the track body 15, and the hydraulic motor and a hydraulic pump provided on the lower traveling machine body 1a are connected by a hydraulic hose. 16. In this case, the rubber crawler is wound around.

Reference numeral 17 is a wheel, and in this case, mounting plates 18 are provided at the front and rear positions of the lower traveling body 1a in the traveling direction,
An oscillating member 19 is pivotally attached to an attachment plate 18 by an upper pivot shaft 20 so that the oscillating member 19 can be oscillated vertically, and the oscillating member 1 and the bottom portion of the lower traveling vehicle body 1a are pivotally attached.
A vertical movement cylinder 21 which is a hydraulic cylinder is pivotally mounted between the vertical movement cylinder 9 and the lower cylinder 9, and in this case, the base portion of the vertical movement cylinder 21 is pivotally attached to the lower traveling machine body 1a by a machine body side pivot shaft 22 so as to project. The rod 21a of the rocking member 1
9 by means of a lower pivot shaft 23, and the center of the axle 17a of the wheel 17 at the time of the minimum contraction movement of the vertical movement cylinder 21 is separated from the upper pivot shaft 20 by a distance L, for example, and is on the fuselage side. It is arranged on the side of No. 22 and is configured by attaching a wheel 17 for running on a rail which is driven by a hydraulic motor (not shown) to a swing member 19.

Reference numeral 24 denotes a lock mechanism, which is a swing member 19
And the lower traveling machine body 1a on the side of the working machine body 1. In this case, a through hole 25 is formed in the mounting plate 18 and a through hole 26 is also formed in the swinging member 19, and the position of this through hole 25 is formed. The boss cylinder portion 27 is attached to the mounting plate 18 in accordance with
A lock pin 29 that can be inserted and removed is formed in both through holes 25 and 26, and a lock pin 30 that can be inserted into the lock groove 28 is provided in the lock pin 29.

Reference numeral 31 is a pulling portion, and in this case, a pair of pulling plates 32 are attached to the swinging member 19 so as to face each other vertically.
The tow plate 32 is configured to be able to connect a tow vehicle such as a truck car (not shown).

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 moved down 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 travel on the rail. The lane mechanism 12 enables crane work to improve workability, and can vertically move the wheels by vertically swinging the swinging member 19, thereby shortening the escape and escape time to the side of the track in an emergency. The work safety can be improved.

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.

During the towing operation, the rocking member 19 is fixed in position by the lock mechanism 24 between the rocking member 19 and the working machine body 1 side as shown in FIGS. Therefore, it is possible to prevent the vertical movement cylinder 21 from extending and the swinging member 19 rising due to the traction force, and prevent the work machine body 1 from falling and the bottom surface or the like of the work machine body 1 coming into contact. It is possible to improve safety.

Although the vertical movement cylinder 21 has a structure using a hydraulic cylinder, other cylinder mechanisms may be adopted and may be appropriately modified and designed.
