Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a sewer gutter cover removal/removal machine that allows even women and elderly people to perform sewer gutter cleaning work easily.

[Prior art]

In the past, drain cleaning work was generally done manually.

In some cases, a sewer cover removal machine with the structure shown below is also used.

To explain in detail below with reference to FIG. 1, the horizontal member 1
A T-shaped handle 3 is provided at the upper end of the vertical member 2, and a T-shaped transverse member 4 is fixed to the lower end of the vertical member 2. A pair of casters 5, 5 are disposed at both ends of the transverse member 4, and a first pawl 7 of a predetermined width is fixed to the lower part of the transverse member 4 to be inserted between the groove lids.

A handle 6 was rotatably attached to one end of the horizontal member 1 with the vertical member 2 sandwiched in the center, and a second claw 8 was fixed at the tip of the handle 6 at a position corresponding to the first claw 7. When the first claw 7 is inserted between the gap formed between the groove cover and the adjacent groove cover, and the handle 3 is tilted down like a lever, the first claw 7 and the second claw 8 sandwich the groove cover, Move the handle 3 out of the gutter while holding it down.

When setting the gutter cover to its original position, when the handle 3 is raised vertically and the handle 6 is also pulled up, the gutter cover is removed and set to its original position.

[Problems to be solved] When manually handling the gutter cover, it is very difficult for women and elderly people to handle it, and even for men who are not elderly, it is difficult to carry it because of their working posture. Moreover, it was a very time-consuming and dangerous work.

When using the sewer gutter cover removal machine described above, the gutter cover dimensions and the cross-sectional shape of the side gutter are as shown in Figures 2, 3, 4, and 5 A, B, C, and D. However, the current situation is that there are a variety of different types, and even within the same area, various types coexist. To explain more specifically, the length of the gutter cover is 600 mm, 500 mm, and various other types, and the cross-sectional shape of the gutter section is taken as an example: a flat type where both sides of the gutter cover are flat, and a type where the road side is for drainage of rainwater. There are various types of roads, such as high ditches, fences on both sides of the ditch cover, stone walls, car stops, etc., with few flat areas.

Considering the above-mentioned usage environment, the first claw 7 and second claw 8 are fixed at a fixed interval in the sewer gutter cover removal machine, so it can only be used with gutter covers of a certain size. However, in order to accommodate various gutter cover sizes, there was a problem in that a plurality of units with intervals matching the gutter cover dimensions had to be prepared.

Furthermore, when the first claw 7 is inserted into the gap formed by the groove cover and the adjacent groove cover, and the handle 3 is tilted down like a lever, the groove cover is held between the second claw 8 of the first claw 7, Handle 3
Since the second pawl 8 moves in an arc and is positioned to the side of the gutter cover, a certain space is required between the gutter cover and the adjacent gutter cover. However, since the gutter cover and the adjacent gutter cover are normally arranged in close contact with each other, there was a problem in that this sewer gutter cover removal/removal machine could not perform intermediate removal work.

Moreover, when the first claw 7 is inserted into the gap formed between the groove cover and the adjacent groove cover, the groove cover is pushed up with force, which causes the problem of destroying the side and bottom surfaces of the groove cover. It was hot.

Also, when setting the gutter cover to its original position, use the handle 3.
Since the groove cover is removed by raising the handle 6 vertically and also pulling up the handle 6, the handle 6
There was also the risk that one's hand might get caught when pulling up the machine.
