DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for detaching and transporting a lid provided at an opening of a gutter and for transporting the gutter.

[0002]

2. Description of the Related Art The following devices have been disclosed as devices for attaching and detaching a cover plate for a gutter. First, JP-A-8-1352
No. 6 discloses a lid gripper that includes a pair of holding members that abut against two opposite side surfaces of the lid to hold the lid, and driving means for displacing the distance between the holding members.

[0003] Also, JP-A-8-53875 discloses that
A jack arranged on a truck, a horizontal suspension rod fixed to the upper end of the jack, and a pair of suspension tools connected to both ends of the horizontal suspension rod, the hooks of the suspension tools being concrete. A gutter lid attachment / detachment device is disclosed in which the lid is attached to and detached from the gutter by operating the jack so as to be engaged with both ends of the lid.

Further, Japanese Patent Application Laid-Open No. 8-225123 discloses that a pair of locking pieces are inserted into recesses provided on the left and right sides of a gutter cover to lock the gutter cover. A gutter lid opening / closing device that can be used to lift a gutter and move it by wheels is disclosed.

[0005]

However, the first prior art (Japanese Patent Laid-Open Publication No. Hei 8-13526) displaces the distance between a pair of holding members that hold the lid by contacting two opposite side surfaces of the lid. Since a driving means is required, the structure is complicated and the manufacturing is not easy. Further, since the lid is sandwiched and held by the plate-shaped holding member, there is a risk that the lid is easily detached and dropped due to the weight of the lid plate. However, it was difficult to hold and move a heavy concrete cover plate in a stable state.

The second prior art (Japanese Patent Laid-Open No. 8-5 / 1996)
In Japanese Patent No. 3875), when a jack handle is moved up and down to raise a horizontal hanging rod, and a pair of hanging tools is used to lift a gutter lid locked at both ends thereof, the both ends of the gutter lid are formed. Since the mechanism for moving the pair of suspenders is provided according to the interval between the parts, the structure is complicated and the manufacturing is not easy. Further, as in the first prior art, both ends of the gutter cover are locked by hooks, so that there is a danger that the gutter cover will be easily detached and dropped due to the weight of the gutter cover. Further, when lifting the side groove cover, the jack must be operated by human power, so that the jack cannot be lifted easily in a short time, which is not efficient.

Further, the third prior art (Japanese Patent Laid-Open No.
Also in Japanese Patent No. 25123), since the rod-shaped locking pieces are inserted into the concave portions provided on the left and right sides of the gutter lid to grip the gutter lid, if the locking pieces are misaligned, the lifting of the gutter lid may be difficult. He was out of balance and dangerous, and was very unstable during transport. Further, similarly to the first and second prior arts, a mechanism for displacing the interval between the pair of locking pieces is provided, so that there is a problem that the structure is complicated and manufacturing is not easy. .

[0008]
