Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a device used for maintenance work of a ballast track, and in particular, a track truck is equipped with a crushing device, a leveling device, and a compacting device. The present invention relates to a roadbed crushed stone arranging and compacting device capable of performing crushed stone scraping and compaction with a single track truck.

[Conventional technology]

Many railroad tracks are made of crushed stone and gradually collapse due to vibration of vehicles. Therefore, crushed stone must be replenished to the roadbed and compacted. Usually, the work area is small for these jobs, so a rope was tied to a scoop and a group of two people picked up the crushed stones by hand and then compacted using a vibrator or the like.

[Issues to be solved by the device]

However, the work of scraping, organizing, and compacting crushed stones by hand is extremely heavy work, and the work efficiency is poor, and it is desired to perform efficiently by mechanical force even in the present situation where manpower is insufficient.

In order to solve the above problems, the present invention is provided with a crushed stone scooping device, a scraping leveling device and a compacting device for one track truck to perform the work of scraping, scattering and compacting crushed stones. An object of the present invention is to provide a roadbed crushed stone arranging and compacting device that can be efficiently carried out by a single track truck.

[Means for solving the problem]

For this purpose, the roadbed crushed stone arranging and compacting device of the present invention has a scraping claw that is driven to rotate. It is characterized in that it is provided with a squeezing means, a squeezing means for crushing the crushed stones on the shoulders and slopes of the roadbed, and a control means for controlling these devices.

[Action]

According to the present invention, one orbital bogie is provided with a crushed stone scooping device, an agitation leveling device and a compaction device so that one orbital bogie can perform from crushed stone scooping to compaction. Adjust the height and angle of the scraping device, etc. to match the shape of the roadbed by adjusting the hydraulic unit, and drive the crushed stone lifting device on the slope of the roadbed while advancing the track carriage forward. As the trolley moves, the scraped crushed stones are scraped and leveled by a leveling device almost level with the sleepers, and finally a metal plate is brought into contact with the crushed stones on the shoulders and slopes of the trackbed. Vibration is applied to the compactor to compact it. Then, after the work is completed, the respective devices are rotated to be stored within the vehicle limit.
