JPS59322Y2 - Vibration hoe for track maintenance - Google Patents

Description

[Detailed description of the invention] This invention relates to a vibrating hoe for track maintenance.In particular, by attaching a vibration motor to the tip of the hoe, the cutting edge of the hoe can be easily moved into the ballast of the track bed by vibration and the weight of the motor. It was made so that you could get into it.

As part of the track maintenance work, old ballast (gravel) that was spread on the trackbed is scraped out and replaced with new ballast.

By the way, in the past, when scraping out ballast from this road bed, a normal shovel was forced into the ballast by hand, and the ballast was scooped up with this, but with this method, the shovel was inserted into the ballast. This method requires a great deal of labor and has low work efficiency.

In other words, due to its nature, the ballast used for roadbeds is difficult to shovel into, and since it is tamped down with a tamping device etc. when it is spread on the roadbed, the reality is that it is almost impossible for shovels to get into it. Met.

The present invention was developed in view of the above points, and by attaching a ballast scraping part shaped like a hoe to the tip of the handle and fixing a vibration motor to this ballast scraping part, To provide a new vibrating hoe for track maintenance, which vibrates a ballast scraping part and allows its cutting edge to easily and deeply penetrate into the ballast.

Hereinafter, the present invention will be specifically explained based on illustrated embodiments.

In Figures 1 and 2, the code 1 is the handle of the hoe, and 2 is the handle 1.
This is a ballast scraping part provided at the tip of the ballast.

This scraping part 2 is formed from an iron part having a hoe-like shape as a whole, and in this embodiment,
Attachment part 21 of handle 1. A fixed part 22 of the vibration motor 3 and a blade 23 that bites into the ballast are integrally provided.

The handle attachment part 21 is connected to the handle 1 via a vibration isolating member 4 which has a rod shape and is made of rubber or other material.

Further, the fixed part 22 of the vibration motor 3 has a substantially flat plate shape,
A vibration motor 3 is fixed to the upper surface by means such as bolt tightening.

Note that 31 is a power cord for the vibration motor 3.

Furthermore, the blade 23 is provided with a plurality of narrow cutting edges in the shape of a comb blade, but the shape of the blade 23 is not limited to that shown in the drawings, and may have a shape that can easily penetrate into the ballast. It can be selected and used as appropriate.

Since the hoe of the present invention has a preemption as shown in the above-mentioned embodiment, when the blade 23 is thrust into the surface of the ballast B as shown in FIG. 23 is the vibration force and the dead weight of the motor applied to the cutting edge (
Further, due to the force of the worker transmitted through the handle 1), the ballast (B) enters smoothly and deeply.

In this case, since the vibration isolating member 4 is provided between the handle 1 and the ballast scraping part 2, the vibration of the vibration motor is not transmitted to the handle 1, and the work can be carried out smoothly.

After inserting the blade 23 into the ballast B in this way, as shown in FIG. 3 II, the handle 1 is pulled and the blade 23 scrapes up the ballast B.

As described above, according to the present invention, the action of the vibration motor makes it possible to easily thrust the blade of the hoe into the ballast, so the amount of ballast that can be scooped up in one operation is lower than that of the conventional shovel. This can significantly increase the efficiency of ballast scraping work.

In particular, since the work of thrusting a blade into the ballast 1-, which was conventionally a hard labor, is performed mechanically using a vibration motor, the effect in terms of reducing the labor of the worker is significant.

Further, since vibrations are not transmitted to the handle 1 by the vibration isolating member, there is no risk of harm to the health of the work tool even during long hours of work.
