Description

The present invention relates to a conveyor. More specifically, in a transporter that is mounted on a lift and can be lifted and moved along a guide, it can be mounted and used regardless of the dimensions of the transporter mounting portion of the target lift. About.

  For example, in the construction of a concrete bridge, a number of height adjustment posts are used to support the concrete bridge under construction (see FIG. 5). As shown in the figure, the height adjustment column is installed on a large number of cross beams passed between pillow beams mounted on temporary columns.

  And after construction of a concrete bridge, after removing a height adjustment support | pillar, a horizontal beam, a pillow beam, and a temporary support | pillar are also removed in order. The horizontal beam and the pillow beam are long H-shaped steel and heavy. A crane can be used to install the cross beams and pillow beams, but the completed bridge is in the way of removal, and the crane cannot be used as it is. For this reason, the horizontal beam is moved out of the bridge along the pillow beam in order from the end, lifted by a crane and removed.

As a means for moving the horizontal beam along the pillow beam, for example, there is a “simple transport device” described in Patent Document 1.
This simple transport device includes a telescopic portion that is mounted in a recessed portion of a lift such as H-shaped steel, and that expands and contracts the upper and lower abutting members, and a pedestal that is arranged to be inclined downward with respect to the recessed portion. A pivoting portion is provided on the end side or on either end side, and is composed of rolling elements that are pivotally supported so as to be able to roll in a cantilevered manner with respect to the pedestal. It can be easily performed by an operator.

JP-A-9-136793

The conventional simple conveying device is mounted in the concave portions on both sides of the lifted load such as H-shaped steel, and at this time, the upper and lower flanges are mounted so as to be stretched by the upper contact member and the pedestal.
However, in the case of H-shaped steel, since it is a standard product, there are various dimensions. In order to cope with them, the transport device having the above structure prepares a number of types of transport devices in advance and adapts them to the situation at the site. It was necessary to select and use a transfer device.

  In this case, when the lifted bag becomes large, in order to cope with it, there is a problem that the transfer device becomes inevitably large and heavy and difficult to handle. In addition, it takes time to select a transport device corresponding to the size of the lifted baggage at the site, and further, it is very expensive to prepare many types of transport devices.

(Function)
FIG. 5 explains the use state of the transporter according to the present invention, (a) is an explanatory diagram showing a construction state of the bridge, (b) is an explanatory diagram showing a state where the H-shaped steel cross beam is removed after the bridge construction. ,
6 is an enlarged view of a portion P in FIG.
FIG. 7 shows the procedure for lifting up the H-shaped steel by the transporter, where (a) is when mounted, (b) is when lifting is started, and (c) is when lifting is completed.

Here, a case where a horizontal beam is removed in the construction of a concrete bridge will be described as an example.
As shown in FIG. 5 (a), a number of height adjustment posts for supporting the concrete bridge under construction are placed on the number of cross beams 5 passed between the pillow beams 4 placed on the temporary support posts. is set up.

After construction of the concrete bridge, after removing the height adjustment struts, the transverse beams 5, the pillow beams 4 and the temporary struts are further removed in order. The horizontal beam 5 and the pillow beam 4 are long H-shaped steels and are heavy objects.
In order to remove the cross beam 5 and the pillow beam 4, the cross beam 5 is moved from the end along the pillow beam 4 to the outside of the bridge, lifted by a crane, and removed.

A method for moving the cross beam 5 along the pillow beam 4 is as follows.
(1) The conveyor main body 1 is mounted at a total of four locations on both sides in the width direction of the lower flange 51 on both ends in the length direction of the cross beam 5. Both sides in the width direction of the lower flange 51 constitute a supported upper portion. First, the upper side portion 113a of the lower jaw portion 113 of the carrier body 1 is placed on the lower surface side of the lower flange 51 of the transverse beam 5 which is a lift and is H-shaped steel, and further the carrier body 1 is pushed in so that the fulcrum portion 114 is moved to the lower flange. 51 abuts against the lower corner of the edge. The conveying roller 14 is placed on the upper surface of the upper flange 41 of the pillow beam 4 whose inside of the stopper flange 140 is H-shaped steel, and the support substrates 11 and 11a are slightly separated from both edges of the upper flange 41 in the width direction. Is located. In addition, before the said operation | work, the carrier main body 1 puts the stopper 19 of both sides on the upper flange 41 upper surface of the pillow beam 4 which is H-shaped steel as needed, and temporarily places it in the state which is easy to move to the next operation | work. You may keep it.

(2) The jack 2 is placed on the upper surface of the lower flange 51 of the horizontal beam 5, and the side surface of the stopper gauge 24 is brought into contact with the edge of the lower flange 51. Thereby, the initial position in the depth direction of the jack 2 is determined (see FIG. 7A).
(3) The handle 22 of the jack 2 is operated, the push rod 25 is extended, and the abutting portion 26 at the tip is fitted into the engaging groove 122 of the abutting member 121 of the transport machine body 1 so as to abut (see FIG. 7 (b)). As a result, the axial direction of the push rod 25 is slightly inclined toward the handle 22 side.

(4) When the push rod 25 of the jack 2 is further extended, the conveyor main body 1 rotates in the direction in which the conveyor roller 14 is lowered around the fulcrum 114 that is in contact with the end edge of the lower flange 51 of the cross beam 5. To do. In addition, in FIG. 7, the rotation direction of the transfer machine body 1 located on the left side of the cross beam 5 is counterclockwise, and the transfer machine body 1 located on the right side is clockwise. Further, the jack 2 is inclined in the above-mentioned direction (left-inclined on the left side in FIG. 7), and the position of the vertical line passing through the center of the contact part 26 and the center of the tilted fulcrum part 23 is that of the contact part 26. It shifts closer to the vertical line passing through the center of the transport roller 14. In addition, it becomes easy to rotate the conveyance main body 1 with the jack 2 by providing the above shifts.

(5) As a result, the conveying roller 14 strongly presses the upper surface of the upper flange 51 of the pillow beam 4 as the guide portion, and the reaction beam causes the horizontal beam 5 to reach a required height by the fulcrum portion 114 of each lower jaw portion 113 (FIG. 7 ( Lifted up in b) of c). Since the upper side portion 113a is inclined, the lower surface of the lower flange 51 hardly interferes with the upper side portion 113a of the lower jaw portion 113 even when the transport machine body 1 rotates. Misalignment can be prevented. Thereby, the stable lift-up of the cross beam 5 is possible. Further, at the time of lift-up, the vertical line passing through the center of the abutting portion 26 and the center of the inclined fulcrum portion 23 becomes the width a (see FIG. 7C) and becomes slightly wider. The support of the member 12 and the both pushing force receiving portions 112 is stabilized, and the lift-up state can be stably maintained.

(6) Then, a force parallel to the direction of the pillow beam 4 is applied to the horizontal beam 5 with the horizontal beam 5 lifted up, and the transfer roller 14 of each transfer machine A is moved along the pillow beam 4 as a running wheel. .
In this way, when the transporter A mounts the transporter A on the horizontal beam 5 to be unloaded, the transporter A attaches only the lower flange 51 to the horizontal beam 5 regardless of the dimensions of the transporter mounting portion of the horizontal beam 5. Can be moved.

  Note that the terms and expressions used in this specification are merely explanatory and are not limiting at all, and terms and expressions equivalent to the features described in this specification and parts thereof. There is no intention to exclude. It goes without saying that various modifications are possible within the scope of the technical idea of the present invention.
