Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a housing unit reloading device, and more particularly to a housing unit reloading device that allows a housing unit loaded on the loading platform of a large truck to be easily transferred onto the loading platform of a medium or small truck. It relates to a transshipment device.

The unit housing construction method involves manufacturing box-shaped housing units in a factory, loading and fixing the housing units onto the loading platform of a truck, and transporting them from the factory to the construction site.
This method is known as a method of constructing a house by assembling the required number of housing units on-site. Conventionally, when transporting a housing unit, one housing unit was loaded and fixed on the platform of one truck, and several trucks were lined up to transport it from the factory to the construction site. As costs have increased, there has been a desire to transport as many housing units as possible using large freight vehicles. In this case, there is no problem when large trucks drive from the factory on expressways and expressways with sufficient road width, but under normal circumstances, it is rare that they can pass through to the construction site, and many In this case, the road becomes narrower and becomes impassable for large trucks before reaching the construction site. Conventionally, a crane truck was used to transfer the housing unit on a large truck onto the loading platform of a small or medium-sized truck. In order to carry out the transshipment work, it is necessary to secure a large space that can accommodate a crane truck, and this also increases the cost and time of transporting housing units from the factory to the construction site, which reduces transport efficiency. There were problems in improving it.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a housing unit reloading device that allows housing units loaded on the loading platform of a large truck to be transferred onto the loading platform of a small to medium sized truck without using a crane truck or the like. There is a particular thing.

SUMMARY OF THE INVENTION The present invention, which achieves the above object, provides an apparatus for transferring one of a plurality of housing units loaded on the platform of a large lorry onto the platform of a small to medium sized lorry. A jacking device provided at the rear lower part of the loading platform to lift the loading platform, and a horizontal holding claw protruding from the rear end of the loading platform of either the large truck or the medium-sized truck and the rear end of the other. A pair of holding claw holders are provided at a position where the horizontal holding claws can be received, and a pair of holding claw holders are provided at a distance in the lateral direction, and the rear ends of the loading platforms of both trucks are connected to each other and the horizontal surface of the loading platform is connected. It is equipped with a horizontal holding device that restricts internal movement, and a winch device that is installed on the side of small and medium-sized freight vehicles to tow the housing unit.

An embodiment of the housing unit reloading apparatus according to the present invention will be described below with reference to the drawings.

First, the structure of the housing unit to be transported will be explained. As shown in Fig. 1, the housing unit consists of four vertical columns 1A, 1 placed at the four corners.
B, 1C and 1D, and these columns are made of hollow box-shaped steel. Further, a floor frame 2 is connected to the lower end of the vertical column, and a ceiling frame 3 is welded to the upper end thereof. The frame member is constructed by framing channel steel or angle steel in a rectangular shape, and includes several reinforcing frames 4,
4, . . . 4 are appropriately spanned in the horizontal direction, and window frames and panel materials are constructed as necessary in areas corresponding to the surfaces of the rectangular parallelepiped. A unit house is completed by appropriately combining such housing units at a construction site.

After the above-mentioned housing unit is manufactured in a factory, it is transported from the factory to the construction site using a truck as described later. At this time, in order to facilitate the transportation work, a roller-type roller is installed at the bottom of the housing unit. Carriage 5 is installed.

As shown in FIG. 2, this carriage 5 has a rectangular base plate 6, and below this base plate 6, four axles 7, 7, 7, 7 extending in the transverse direction are arranged equally. Wheels 8, 8 are rotatably mounted on both ends of each axle 7, which are arranged at intervals. Further, a center pole 9 extending upward is fixed to the center portion of the base plate 6, and this center pole 9 is formed in a tapered shape, and can be installed from below into the hollow hole of the vertical column 1 of the housing unit. It's becoming like that. Furthermore, the base plate 6 before and after the center pole 9 is
Pin insertion holes 10, 10 are formed therethrough.

Next, a large truck L for transporting the above-mentioned housing units from a factory will be explained with reference to FIG.

This is a cap-over type truck,
The loading platform 11 does not have side gates or rear gates, and a torii gate 12 is provided at the front end. Guide rails 13, 13 are laid and fixed along the longitudinal direction on both sides of the loading platform 11. In addition, hydraulic jacks 14, 14 as a jacking device are installed at the bottom of both sides near the rear end of the loading platform 11, and this hydraulic jack 14 has a cylinder main body 1 on the loading platform side.
4a is fixed, and a grounding shoe 14c is attached to the tip of the piston rod 14b. This hydraulic jack 14 may be fixed or foldable.

Further, at the rear end of the loading platform 11, two loading platform horizontal holding claws 15, 15 are provided to protrude rearward. This holding claw 15 may be of a fixed type, a removable type, or a movable type that can move forward and backward.

Usually, two housing units A and B are loaded onto the loading platform 11 of the large freight vehicle L configured in this way. 11 is lowered onto the carriage 5, 5, 5, 5, which is placed on the carriage 11. If this continues, there is a risk that housing units A and B may move back and forth, so please set the position in advance and align the receiving hole drilled on the loading platform 11 with the pin insertion hole 10 of the carriage 5. A carriage fixing pin 17 (see FIG. 2) can be inserted from above to prevent movement in the front-rear direction.

Incidentally, when the two housing units A and B are loaded on the loading platform 11 in this manner, the floor surface of the loading platform 11 moves downward due to their own weight. This large truck is used to transport housing units A and B to the location closest to the construction site, and one of them is transferred to a small to medium truck S along the way.

Next, the structure of the freight vehicle S to be transshipped will be explained with reference to FIG. This freight vehicle is a small to medium-sized cab over truck, and guide rails 2 are provided along the entire length on both sides of the loading platform 21.
2, 22 are laid and fixed, each guide rail 22,
Direction correction guides 23, 23 are mounted near the rear end of the loading platform 22. These direction correction guides 23, 23 gradually widen the width of the loading platform 21 toward the rear to facilitate the introduction of the housing unit A during reloading.

Further, holding claw receivers 24, 24 are mounted below the rear end of the loading platform 21, and each of the holding claw receivers 24 has a socket into which the holding claw 15 can be inserted.

Furthermore, a winch 25 is installed below the torii at the front end of the loading platform 21.

First, a large truck L stops at a place near a construction site where it has become impassable, and as shown in FIG.
Insert. The thickness of the ring 32 is determined in consideration of the height at which the loading platform 11 is lifted. Next, the hydraulic jacks 14, 14 are prepared for operation. Next, the small lorry S approaches the rear end of the loading platform 11 of the large lorry L from behind and is temporarily stopped.

Next, the hydraulic jack 14,1 of the large freight vehicle L
4 is driven to lift the loading platform 11, and the heights of the floor surfaces of the loading platforms 11 and 21 of both freight vehicles L and S are made to be the same. When the heights are even, the small truck S is further tilted back, and the horizontal holding claws 15, 1
5 and the receiving metal fittings 24, 24 (see FIG. 6).

Next, housing units A and B on the L side of the large freight vehicle
The fixing pin 17 inserted into the carriage 5 of
17, . . . 17 are extracted and prepared for transshipment.

Hook the unit tensioning fitting 29 below housing unit A to be transshipped first, and use the winch 25 to
The towing rope 27 on the winding drum 26 is wound back, and the hook 28 at the end of the towing rope is hooked onto the unit tension fitting 29.

Next, the driving machine is driven in the winding direction, and the housing unit A is moved from the loading platform 11 of the large vehicle L to the loading platform 21 of the small truck S with the carriage 5 attached thereto (see FIG. 7). When the housing unit A reaches a predetermined position on the loading platform 21 of the small truck S, the winding of the winch 25 is stopped, and the fixing pin 17 is inserted into the carriage 5 to firmly fix it.

When the relocation of the housing unit A is completed in this way, the small freight vehicle S is moved forward toward the construction site. Next, using another small freight vehicle S, the remaining housing unit B is reloaded using the same procedure. Once all transshipment is complete,
The work is completed by driving the hydraulic jacks 14, 14 in the direction in which the pistons retract, moving the vehicle L forward, and removing the wheels 32.

As described above, according to the present invention, the loading platform of a large lorry is lifted using a hydraulic jack to match the floor level of the loading platform of a small lorry, and one of the housing units is lifted using a winch. It becomes possible to transship housing units from large lorries to small lorries. In this way, since it is only necessary to butt the rear ends of the two freight vehicles against each other, there is no need for a crane truck or the like at all during transshipment, and the transportation work can be carried out quickly and at low cost. Furthermore, since the loading platforms of both trucks are connected via the horizontal holding pawls during transshipment, the work can be carried out safely without any sideways displacement of the vehicles during transshipment.
