Description

[Detailed description of the device]

[0001]

[Field of Industrial Application] The present invention is used for exchanging roadbeds in which a backhoe is mounted on a truck that moves on a rail, and a conveyor device is arranged below the backhoe to exchange the sediment of the roadbed in a narrow place such as a tunnel. The earth and sand carrying-out device.

[0002]

2. Description of the Related Art Conventionally, machines for exchanging roadbeds have a backhoe with wheels attached to the front and rear to run on a track.

[0003]

In the backhoe on the rail, the bucket is usually pulled toward the machine to excavate the earth and sand and rotate 90 to 180 ° and load it on the dump truck.
In a narrow place such as a tunnel, it took time for the boom, arm, bucket, etc. to load the excavated earth and sand due to the vehicle limit.

[0004]

SUMMARY OF THE INVENTION In view of such circumstances, the present invention addresses the above-mentioned problems by rapidly transporting excavated earth and sand to the rear portion via a conveyor, and loading and unloading the dump truck on standby. Is provided for the purpose.

[0005]

In the present invention, the backhoe 5 is mounted on the carriage 1 moving on the rail 4 via the guide plates 6 and 6, and the backhoe 5 is moved by the carriage 1 to the exchange position of the tunnel bed. 4 is controlled by the braking means 18 from the trolley 1, the conveyor device 16 is tilted to drive the belt, while the backhoe 5 on the trolley 1 is operated to excavate with the bucket 13, and the excavated earth and sand are The boom 9 and the support arm 11 are operated by a hydraulic ram, and the earth and sand in the bucket 13 are thrown into the hopper 17 provided on the front side of the conveyor device 16, and the earth and sand in the hopper 17 are moved to the rear part by the conveyor device 16. It is transported and loaded onto a dump truck that is on standby on the rear rail 4 and is unloaded. Also, new earth and sand will be supplied to the excavated roadbed.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an embodiment of the earth and sand carrying-out device in the roadbed exchange according to the present invention. The present invention will be described below with reference to this drawing.

1 is a trolley, and wheels 2 and 3 are provided in front of and behind the trolley 1.
Is provided to enable traveling on the laid rail 4.

At the rear end of the truck 1, one end of guide plates 6 and 6 for mounting the backhoe 5 described later is pivotally attached, and provided so as to be foldable so that the backhoe 5 can be loaded on the truck 1 by the guide plate 6. The other ends of 6 and 6 are put on the orbit.

The backhoe 5 is provided with a machine body 8 on a swivel base 7 located on the base lying on the endless track C, and one end of a boom 9 is pivotally attached to the front end of the machine body 8 and the boom 9 is lifted by a hydraulic ram 10. It is designed to be lowered.

The boom 9 has a support arm 11 on the front end side.
Further, the extension of the support arm 11 from the pivotal connection portion connects the other end of the hydraulic ram 12 whose one end is connected to the boom 9 side so that the support arm 11 can be swung back and forth. is there.

A bucket 13 is attached to the free end of the support arm 11. The bucket 13 connects the other end of a hydraulic ram 14 having one end connected to the support arm 11 and a space between the support arm 11 and the hydraulic ram 14. Is lever 15
Are connected to each other. Therefore, the hydraulic ram 14 causes the bucket 13 to swing around the tip of the support arm 11.

A conveyor device 16 having a drive unit at one end between the carriages 1 below the swivel base 7 of the backhoe 5.
Is located in the front-rear direction, and a hopper 17 for charging the earth and sand excavated by the bucket 13 is provided integrally with the conveyor device 16 at the upper part on the front side of the conveyor device 16. I try to lean around.

Reference numeral 18 in the figure denotes a braking means.

[0014]

As described above, according to the present invention, the backhoe is mounted on the truck that moves on the rail, and the conveyor device is located under the backhoe, and the earth and sand excavated by the backhoe is immediately moved backward by the conveyor device. It is carried and loaded on a dump truck, and particularly in the work in a narrow place such as a tunnel, conventionally, when excavating earth and sand and turning 90 to 180 ° and loading on a dump truck, boom, support arm, bucket It took a lot of time to load the earth and sand due to the vehicle limits, construction limits, etc.
As described above, since the soil is immediately carried to the rear, there is no hindrance, and the work is rationalized and the efficiency is improved.
