Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a gutter cover lifting device that sequentially and continuously lifts and lowers the cover of an extending gutter.

In general, in ditches that serve as sewage channels and irrigation channels, sediment such as sludge accumulates on the bottom of the ditch due to long-term use, and this must be removed periodically.

By the way, when removing the sediments mentioned above, if the top surface of the ditch is covered with a lid, it is necessary to open the lid to remove the sediments, and even if the ditch is large or small, the ditch cover must be closed. If the top surface is a part of the road and is thick, the lid becomes quite heavy.

Previously, a crane truck was used to open the heavy lid, or several workers worked together to open the lid.

For this reason, there have been disadvantages in that secondary operations other than the removal of settled matter, such as selecting a place to place the open lid and fatigue of the operator, are troublesome, and safety is compromised.

The present invention was developed in view of the above-mentioned circumstances, and its purpose is to lift the plurality of lids that obstruct the removal work of settled objects upward one by one according to the progress of the removal work, and then By lowering it, the above-mentioned secondary work can be performed simply and safely, thereby making it possible to efficiently remove the sediment in the ditch.

In order to achieve the above object, the present invention is characterized by the following configuration.

That is, a frame extending in the extending direction of the ditch and curved upward in an arc shape is mounted on a traveling body that runs along the upper edge of the ditch, and the frame is placed along the extending direction of the ditch. An endless conveyor is wound around the frame, and the frame is driven forward along the ditch by a running body, and the conveyor is rotated in the direction opposite to the forward movement of the frame, and the conveyor covers the ditch located in the front part of the frame. is sequentially lifted up along the upper surface of the frame, then lowered and sent back, and then placed again on the upper edge of the ditch at the rear of the frame.

Hereinafter, an embodiment in which the configuration of the present invention is embodied will be described based on the drawings.

FIG. 1 is an explanatory side sectional view of an embodiment according to the present invention;
FIG. 2 shows an explanatory longitudinal sectional view taken along the line ■-■.

In the figure, 1 is a ditch that serves as a sewer, irrigation canal, etc.
It is made of concrete and has a rectangular cross section with an open top.

The upper edges 2 of the ditch 1 are formed in a step-like manner, and the upper surface of the ditch 1 is closed off by extending concrete M3 over these upper edges 2.

At the location where settled matter such as sludge and fallen objects in ditch 1 is removed,
An elevating device 4 for elevating and lowering the lid 3 existing at the location is arranged.

This lifting device 4 includes a traveling body 5, a frame 6, a conveyor 7
as its main part.

The traveling body 5 is composed of an endless track band that runs on the upper surface of the rain upper edge 2 of the ditch 1, and is driven forward by a hydraulic motor (not shown), which will be described later.

Further, it is mounted on the frame 6 and the traveling body 5 and driven, and is configured as follows.

That is, a pair of left and right lower frames 8, which are slightly narrower than the width l□ of the ditch 1 and extend linearly in the extension (back and forth) direction of the ditch 1, are locked to the shafts of the wheels 9 of the traveling body 5. do.

Then, the lower frame 8 is attached to the front and rear ends of the lower frame 8.
The front and rear ends of the upper frame 10, which has the same width and is curved upward in an arc shape, are fixed.

This upper frame 10 is made up of a pair of left and right upper rails 11 and a pair of left and right lower rails 12 that are integrally connected to each other by a connecting rod 13, and a number of transfer rollers 14 are projected upward between the upper rails 11. A plurality of guide trollers 15 are installed between the lower rails 12 at predetermined intervals in the front-rear direction.

In the figure, reference numeral 10a designates guide plates that extend and are fixed to both sides of the upper frame 10.

On the other hand, at the front end of the lower frame 8, a raising pawl 16 for raising the lid 3, which has a rearward slope from a lower position to an upper position of the lid 3, is installed and fixed.

Furthermore, an axle 17 is installed at the front and rear ends of the lower frame 8, respectively, and a pair of sprockets 18 are provided on the left and right sides of the axle 17.

Further, an idler wheel 19 is provided at the rear of the lower frame 8 to carry the rear load of the frame 6.

The endless conveyor 7 described above is wound around and supported on the frame 6 configured as described above.

The conveyor 7 has its front and back ends wound around sprockets 18 attached to the front and rear ends of the lower frame 10, its middle upper half placed on a transfer roller 14 attached to the upper rail 11, and its middle lower half The section is suspended and supported by a guide troller 15 attached to a lower rail 12.

Further, the conveyor 7 is provided with engaging claws 20 that engage with the front edge of the lid 3 at a predetermined interval in the longitudinal (back and forth) direction of the conveyor 7, that is, at an interval corresponding to the length t) 2 of M3 in the front and back direction. protrude upward and fix it.

In addition, the above-mentioned lifting device 4 includes a drive device 21 to be described later.
Attach.

That is, the drive device 21 suspends and supports a bottomed box-shaped case 22 on the lower frame 8, and divides the case 22 into two in the front and back direction by a partition plate 23. A hydraulic pump 26 is housed therein, and a rear chamber 27 is filled with driving oil 28.

Here, the drive device 21 uses a hydraulic pump 26 driven by an engine 25 to circulate oil 28 in the rear chamber 27 to the traveling body through each circulation oil path 29 and a valve (not shown) that opens and closes the oil path 29. The hydraulic motors (
By providing a hydraulic motor (not shown) and starting each hydraulic motor with the circulating oil, each wheel 9
- Set each sprocket 18 to be driven in a predetermined rotation direction.

That is, the hydraulic motor is set to rotate the traveling body 5 in the direction of arrow A (forward direction) and the lifting device 4 in the direction of arrow A.

Note that the drawings show an example of the mounting position of the drive device 21, and are not limited to this position.

Next, the operation of the above embodiment will be explained.

First, in order to secure the space required to install the lifting device 4 in the ditch 1, a predetermined number of lids 3 are removed from the ditch 1, and the lifting device 4 is installed at the removed locations using a crane or the like.

Next, after starting the engine 25 and driving the hydraulic pump 26, the circulation oil path 2 leading to the conveyor 7 and the traveling body 5 is opened.
Open valve 9.

As a result, the conveyor 7 rotates in the direction of arrow A, the traveling body 5 rotates in the direction of arrow A, and the elevating device 4 moves forward (arrow 2).

When the elevating device 4 moves forward, the raising claw 16 located at the front end of the elevating device 4 sequentially raises the lid 3 located in front of the elevating device 4.
Next, the lid 3 is lifted up by the conveyor 7 along the upper frame 10 via its engaging claw 20, and then sent down and returned to the upper edge of the ditch 1 at the rear of the upper frame 10, that is, at the rear of the lifting device 4. It will be placed in Section 2.

In this case, since the ditch 1 opens wide at the location where the lid 3 is lifted, the suction hose 31 can be inserted from the side of the lifting device 4 toward the inner bottom of the ditch 1, or an operator can enter from the side. In this way, the sediment 30 in the ditch 1 can be removed toward the side of the lifting device 4.

As explained above, according to the present invention, the lid that closes the top surface of the ditch is raised and lowered sequentially in accordance with the progress of the work to remove settled matter in the ditch.
There is no need to prepare a storage location for the opened lid or to perform complicated transportation work for this purpose.

Therefore, it is possible to safely and efficiently remove the settled matter in the ditch.
