Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to an ultra-mini work tunnel that performs work such as digging or digging holes in places where conventional power vehicles cannot enter, such as narrow alleys. .

(Prior art) Traditionally, one person had to rely on one person to perform tough work in alleys where power could not be accessed, but outdoor physical work is not preferred by young workers these days, The downward trend in age is getting older. Therefore, there are many occupational diseases such as back pain.
The work efficiency was not improved and the productivity was poor.

Therefore, by downsizing the power i1j, it has been possible to work in narrow spaces such as alleys.

(Problem to be solved by the invention) However, since conventional power vehicles have working equipment, an engine, a driver's seat, etc. all mounted on one vehicle, a small body 111 of at least 1 m in length is present. This made it impossible to work in narrow spaces such as between houses.

The present invention has been made in view of the above points, and the working equipment section mounted on the small wheel is operated by power supplied from a separate power source, and is made smaller and narrower than the entire vehicle. This provides an ultra-mini work tank that can be easily accessed even in difficult places.

(Means for Solving the Problems) The present invention provides that the vehicle can be used as a simple hand-push irt (it is possible to use power as an auxiliary), and only a fliii cutting part is mounted on the push-pull. The structure is such that power is supplied from another power source such as a dump truck or a crane 1i.

(Example) An example of an excavator according to the present invention will be described based on the drawings. Fig. 1 is a side view of the whole, and l is a handcart having caterpillars 2, and the rear side is used for direction change. It has wheels that can appear and retract at will, and may be used to drive when changing direction or driving on a flat road. Reference numeral 3 denotes a turning platform installed on the loading platform 4 of the handcart 1, which can be turned manually or by hydraulic power.

The base end of a first boom 6 is pivotally supported 7 at the end of a bracket 5 erected on the swivel base 3, and the base end of a second boom 8 is pivotally supported 9 at the tip of the first boom 6. The refracting boom 10 is constructed as follows.

I+ is a packet pivotally supported at the tip of the second boom 8, and a hydraulic cylinder 12 installed between the second boom 8 and the packet 11.
It swings up and down.

13 and +4 are hydraulic cylinders installed between the first boom 6 and the second boom 8 and between the first boom 6 and the bracket 5, respectively, and are used to swing the first boom 6 and the second boom 8, respectively. .

15 is the handrail of wheelbarrow 1! With the operation lever provided at 6,
It is installed in a position where the operator can operate it during excavation work.

Reference numeral 17 denotes a counterweight, which is detached when the total weight is heavy and is difficult to transport by hand, and is attached to the handcart 1 only at the start of work. Therefore, it may be formed into a bag and water may be injected into the bag only during work.

Reference numeral 18 denotes a working vehicle such as a dump truck or a crane truck, which has a branch circuit in its original hydraulic circuit, and supplies hydraulic pressure to the aforementioned hydraulic cylinders 12, 13, and 14 from this branch circuit.

19 is a hose reel, 20 is a hydraulic hose, and the tip of the hydraulic hose 20 is connected 22 to the operating part 21 at the bottom of the operating lever I5 during work.Next, the excavation work according to the present invention will be explained. Only the handcart 1 is moved manually to the work site, and then the tip of the hydraulic hose 20 is pulled out from the hose reel 19 and connected 22 to the operating part 21 below the operating lever 15.

Then, if necessary, the counter eight 17 is installed.

Next, the operator operates the operating lever 15 to control each cylinder 12. +3. Extend and contract 14 and perform excavation work using packet 11.

If there is room on either side of the earth and sand after excavation, the packet 11 is turned and disposed of on the left and right sides.

If there is no room, the necessary area is first dug with a packet, and then the handcart is moved backwards and the earth and sand are removed manually. It should be noted that the present invention is not limited to excavating vehicles, but may also be applied to large digging vehicles as shown in FIG.

(Effects) As described above, this invention separates the power source and the work equipment part, and only the work equipment part enters the work site, so it can easily enter into narrow spaces where conventional power equipment cannot enter. It becomes possible to perform excavation work and hole digging work using power instead of manual labor.
