An operation fulcrum of a mechanism for nipping the side ditch cover is composed of bearings 2c and 2d by four sets of pipes. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to an apparatus used when installing or removing a gutter lid.

  When installing or removing the side gutter lid, the conventional side gutter lid installation machine cannot move the side gutter lid in the horizontal direction during the hanging and lifting operation, so it is difficult to install or remove the middle side gutter lid with the left and right side gutter lids and a small gap. .

  Since there are few bearings in the conventional mechanism for sandwiching the side groove lid and the contact surface of the bearing is small, the load per unit area of the bearing is large, and the operation of the mechanism is unstable.

In addition, the following patent document 1 and patent document 2 can be mentioned as a well-known technique relevant to this invention.
JP 2001-80872 A JP 2002-255323 A

  In the conventional side gutter lid installation machine described above, even if it is attempted to install or remove a side gutter lid with few gaps on the left and right sides, it is difficult to perform installation etc. because it interferes with the left and right side gutter lids. Requires positioning.

  In addition, since the bearing area that receives the load of the side groove cover is small and the load per unit area of the bearing is large, the mechanism that sandwiches the side groove cover is difficult to move, and it is difficult to lift without reliably sandwiching the side groove cover.

  An object of the present invention is to solve the problems of such a conventional mechanism, and it is possible to smoothly install or remove the side groove cover, and to sandwich and lift the side groove cover with certainty.

  And in order to achieve the said objective, this invention set it as the structure which can be moved to a horizontal direction to some extent or more in the state which suspended the gutter lid installation machine.

  The solution to the second problem is a simple structure in which the shaft and the bearing are a combination of a round bar and a pipe and are provided at four locations.

  The operation of the first problem solving means is as follows. That is, since the gutter lid installation machine is structured to be freely movable in a horizontal direction to some extent while being suspended, it can be installed smoothly even if the position of the carriage or the like is not an accurate position.

  In addition, the second problem-solving means has an effect that the structure is simplified by using the shaft and bearing of the combination of a round bar and a tube, and the load per unit area of the bearing is reduced by providing four sets, so that reliable operation is achieved. It can be lifted with the side groove lid sandwiched between.

  As described above, the side groove cover installing machine of the present invention can smoothly install the side groove cover even in a place where the left and right gaps are small.

  Further, by providing four sets of bearings as pipes, a simple structure is obtained. By reducing the load per unit area of the bearing, the operation of the mechanism for sandwiching the side groove lid can be performed reliably.

BEST MODE FOR CARRYING OUT THE INVENTION

  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

  In FIG. 1, reference numeral 1b denotes a connecting frame which is joined to a bearing by a tube 2c2d and receives the load of the left and right shafts 3a3b.

  The L plate 4a on the left side of FIG. 1 is joined to the shaft 3a as shown in FIG. 2, and the shaft 3a is inserted into the bearing 2c. The right L plate 4b, the shaft 3b, and the bearing 2d have the same configuration as the left side.

The L plate 4a on the left side of FIG. 1 is joined to the brace 5a, and a U-shaped ring 6a is joined to the tip of 5a.
The right L plate 4b, the arm bracket 5b, and the U-shaped ring 6b have the same configuration as the left side.

  FIG. 2 is a plan view of the gutter lid setting machine projected from above.

  In the middle of FIG. 1, the hanging tool 7 is a flexible structure such as a wire rope, and the inside of the left and right U-shaped rings 6a6b is passed through and connected to the insulator cart shown in FIG.

  The operation of the above configuration will be described below. In FIG. 1, when the suspending tool 7 is pulled up, the U-shaped ring 6a6b is moved upward, and the arm metal 5a5b joined to the U-shaped ring 6a6b is rotated around the shaft 3a3b, and the side groove is formed by the L plate 4a4b joined to the tip. Insert the lid. If the suspending tool 7 is further pulled up in this state, the side groove cover can be lifted, and the side groove cover can be installed or removed.

  Further, as shown in FIG. 2, the shaft 3a3b is combined with the bearings 2a2b2c2d, and the load is distributed to four to reduce the load per unit area of the shaft, so that the shaft can be smoothly rotated and the side groove lid can be sandwiched and reliably lifted.
