DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transport vehicle for transporting a long roof material when roofing, and more particularly, to a transport vehicle for a metal plate long roof material having a folded structure.

[0002]

2. Description of the Related Art Conventionally, steel-frame factories, warehouses, gymnasiums,
The roof of the building such as leisure facilities is made of folded metal plate
(Zinc iron plate, steel plate, corrosion-resistant aluminum alloy plate, etc.) long roof material is used. Such a long roof material having a folded structure has various structures, and both ends thereof are overlapped and roofed. The roof material having the folded structure is formed into a predetermined shape from a long metal plate wound in a roller shape by a forming machine installed on a tower set provided on the ground or adjacent to a building. Then, the formed folded roof material must be transported to a predetermined location where it is blown up from the molding location. In particular, the spraying of several meters at the beginning of the roofing requires a lot of manpower, and the work efficiency is not only poor due to the manpower, but also dangerous.

That is, in general, folded roof materials are almost always formed on a ridge, and are transported to a blow-up place where a tight frame is welded in advance. FIG. 10 is a perspective view for explaining a site for forming a folded roof material installed on a ridge. A folded roof material forming site is provided adjacent to a girder 3 formed by welding a tight frame 1. The molding site has a floor 5 formed of a long plate material on a set of turrets (not shown). The floor 5 has a folded roof material forming machine 7 and a roof material carrier 9 placed at an appropriate interval in front of the machine.
Consists of The folded roof material forming machine 7 forms a predetermined shape while extruding a set long metal plate, and can extrude a metal sheet from a length of several tens of meters to several hundreds of meters.

[0004] The roofing material carrier 9 has a pair of left and right support legs 10 which can be opened and closed.
3 and a rotatable roller 15 is attached to the upper end of the column 11. The folded roof material 17 extruded from the molding machine 7 is conveyed while being supported by the rollers 15 and cut by a predetermined length. The cut roof material 17 is transported to a predetermined place where the roof material 17 is lowered from the roller 15 and blows up. The folded roofing material 17 dropped from the rollers 15 is transported by a transporter, but the first few meters of the roof had to be transported by hand because the location was too small to use the transporter.

[0005]

Problems to be solved by hand have the following problems. In other words, transporting a long folded roof requires a large number of people, and it has been difficult to secure the required number of people. In addition, since the formed folded roof must be lowered from the rollers 15 for transport, the work efficiency is not only poor, but also the roof material may be deformed by being dropped and may be injured.

[0006] A work cart as shown in FIG. 11 is used for attaching the tight frame 1 to the beam 3. The work cart 19 has bearings 21 at four corners of an upper plate 20, and rollers 25 having flanges 23 at both ends are rotatably mounted between the bearings 21. The work cart 19 travels on the girders 3 such as H steel while restricting the lateral displacement by the flange 23. In order to attach the tight frame 1 to the girder 3 using the work cart 19, it is possible to use one unit at a time. However, if one unit is used, there is a risk of falling due to poor stability. Usually, two or more units are used in parallel. That is, as shown in FIG. 12, the work board 27 is placed on two or more work carts 19 to prevent the work board 27 from falling down, and the tight frame 1 to be used is placed on the work board 27. Then, the operator sits on the work plate 27 on the work cart 19 while putting his foot on the girder 3. The operator retreats while welding the tight frame 1. In this manner, the tight frame 1 is sequentially welded onto the beam 3.

[0007] The welding work of the tight frame 1 by the above-mentioned workers requires a plurality of workers to work together as a group, and the working efficiency is poor. In addition, working backwards requires confirmation of the rear, and when it hits another girder, it must be lifted and moved. But it was. Further, the bogie can be used only for tight frame welding, and cannot be used for carrying folded roof materials.

[0008]

The height adjusting plate 39 has a substantially triangular shape and is mounted at right angles to the tight frame locking plate 38, with a space provided between the upper plate 35 and the connecting plate 43. . The height adjusting plate 39 adjusts the height of the upper plate 35 when the worker sits down, and also supports the both ends of the upper plate 35 to prevent deformation of the upper plate.
At one end of the upper plate 35 in the longitudinal direction, a substantially L-shaped stopper 47 for preventing the mounted tight frame from dropping is provided in a bolt hole 48 formed in the upper plate 35 with a bolt 49.
, And are removably attached by tightening with a nut 50. In the illustrated embodiment, three height adjusting plates 39 are used on one side. However, the height adjusting plates 39 can be appropriately increased or decreased according to the thickness and size of the upper plate.

Next, the roof material transporting section 33 is constituted by rotatably supporting a roller 53 on a bearing 52 erected substantially at the center of a frame 51 attached to the upper plate 35. The roller 53 is axially supported in the same direction as the tight frame insertion groove frame 37. The upper end of the bearing 52, when the folded roof material is placed on the roller 53, so that the folded roof material does not contact the bearing 52,
The roller 53 is formed lower than the upper end. Further, the frame 51 is larger than the width of the upper plate 35, and a bolt hole 54 is provided at a position overlapping the bolt hole 41.
, Which are detachably attached by bolts 55 and nuts 57. The roof material transporting unit 33 includes:
Attached when transporting folded roof materials, and removed when used as a work vehicle for welding tight frames.

FIG. 4 shows a second embodiment of the bogie in which the roofing material transport section is omitted. This embodiment differs from the first embodiment in that the tight frame insertion groove frame 37 is directly fixed to the upper plate 35, and the height adjustment plate 39 is omitted. That is, the truck 6
0, the connecting plate 63 of the tight frame inserting groove frame 65 formed by connecting the tight frame locking plate 61 having a height higher than that of the first embodiment with the connecting plate 63 is directly fixed to the lower surface of the upper plate 67. Become. The upper plate 67 has a bolt hole 41 formed therein. In addition, rollers 45 that can run on the girder are supported at the four lower corners of the tight frame locking plate 61,
A stopper 69 is integrally fixed to the upper plate.

FIG. 5 shows a third embodiment of a bogie in which the roof material transporting section is omitted. This embodiment is different in that the tight frame locking plate is directly fixed to the upper plate, and the roller is supported by the support frame. That is, the two parallel tight frame locking plates 70 are directly fixed to the lower surface of the upper plate 71, and the support frame 73 and the tight frame locking plate 70 fixed to the lower surfaces of the four corners of the upper plate 71 make the roller 45 Are rotatably supported. The support frame 73 supports the roller 45 and reinforces the upper plate 71. In the upper plate 71, the folded piece 40 is omitted, a bolt hole 41 is formed, and a stopper 75 is integrally fixed to an end.

Next, a method of using the folded roof material carrier will be described. First, the folded roof material carrier 30 in which the roof material transporting unit 33 is attached to the cart 31 is disposed in front of the folded roof material forming machine. The roofing material carrier according to the present invention can omit a roofing material forming site in which a floor is provided on the turret assembly described with reference to FIG. That is, without providing a roofing material forming place, the folded roofing material carrier 30 is arranged on each girder in place of the roofing material carrier 9 and extruded directly from the folded roofing material forming machine 7 onto the rollers 53. The roofing material extruded into a predetermined shape is conveyed one after another by the rollers 53 and cut into a predetermined length. The roof material placed on the rollers 53 may be transported to a place where the trolley 31 is blown up by running on the spar. When the roofing material is lowered, both sides of the roofing material are inclined, so that the roofing material can be lowered diagonally along the side surface by shifting the bottom surface.

Since the extruded folded roof material is directly placed on the transport vehicle, there is no need to transfer the folded roof material, and the carriage 31 can be transported safely because the tight frame is inserted. Since the carriage 31 is locked by the tight frame, the carriage 31 can independently and safely travel without connecting a plurality of carriages with a work board or the like.

Further, by removing the roofing material transporting section 33, the roofing material transporting section 33 can be used as a work cart when welding a tight frame. As shown in FIG. 7, first, the first tight frame is welded to the girder, and this tight frame is inserted into the tight frame insertion groove frame 37, and the carriage 31 is mounted on the girder. Thereafter, the tight frame to be used is placed on the stopper 47 side, and the operator sits on the front end and welds the next tight frame, and advances the bogie 31 to the welded tight frame side. In this manner, the tight frame may be welded one after another and the carriage 31 may be moved forward.

Since the bogie 31 moves forward, it is easy to confirm safety and can be operated with ease. Also, since it is locked on both sides of the welded tight frame, it can be used independently without fear of falling.

Next, referring to FIGS. 8 and 9, a description will be given of an example of use in the case of using a folded roof material having a small width. As in the above-described embodiment, when the folded roof material extruded from the folded roof material forming machine is directly conveyed by the rollers 53, the folded roof material having a narrow groove may fall down to a length of several tens of meters, There are things that need to be supported manually. Therefore, in this embodiment, a half roof material support mechanism for preventing the roof material from falling down is detachably attached to the frame 51.

That is, in the folding roof material supporting mechanism, a substantially V-shaped supporting frame 80 is mounted via a hinge 79 to a mounting frame 77 which is detachably fitted to the frame 51 and is mounted thereon. The supporting roller 81 is rotatably supported so as to face the inside of the support roller 81. The support roller 81 is pivotally supported at substantially the same angle as the side surface of the half-roof material so as to contact the side surface (outer surface) of the half-roof material conveyed by the roller 53, and the interval is set by the support roller 81 facing the same. When supported, the half-roof material is transported while being placed on the rollers 53. Further, the support frame 80 is rotated by a hinge 79, and is placed on the upper surface of the mounting frame 77 when standing up,
It is mounted so that it turns horizontally or downward when it is turned down.

Therefore, when the folded roof material support mechanism is mounted on the frame 51 so as to be in the same direction as the roller 53, the folded roof material is transported by the roller 53 and the support roller 81 without falling (see FIG. 9). When the half roof material is to be lowered from the rollers 53, the support frame 80 may be turned horizontally and downward. By folding the support frame 80, the support of the folded roof material by the support roller 81 is released and the folded roof material can be moved horizontally, so that the folded roof material can be easily pulled down at a predetermined position (see FIG. 8).

The folded roof material carrier according to the present invention is not limited to the above-described embodiment, but may be any other type as long as it has a structure in which a tight frame is inserted and both upper and lower portions of the welded tight frame are locked. The frame locking plate may have a structure in which a plurality of through holes are provided, or may be a lattice frame. Further, the connecting plate connecting the upper ends can be omitted without forming the tight frame locking plate in a U shape by the connecting plate. In addition, the structure for attaching and detaching the carriage and the roofing material transporting section can be changed to a known structure such as a fitting method or a stopper method in addition to the bolt method as in the embodiment. Further, the roller on which the roof material is placed and rotatable is not limited to the case where the roller is detachably attached to the upper plate via a frame as in the embodiment, and the roller is directly mounted on the upper plate without the frame. A structure that can be detachably attached to a standing bearing may be used.

[0024]

According to the folded roof material carrier of the present invention, since the folded roof material carrier is composed of a bogie and a roof material transporter, the roof material extruded from the roof material forming machine can be directly placed and transported as it is. Then, the work of transferring to the cart is unnecessary, and the number of work steps can be reduced and the work efficiency can be improved. In addition, a special extruder is not required as in the related art, and costs can be reduced. In addition, by removing the roof material transporting section, the truck becomes a carriage for tight frame welding work, and safe welding work can be performed.
