Description

[Detailed description of the invention] <Industrial application field> The disclosed technology is for the structure of a device that transfers the cargo of units such as prefabricated houses from a large transport vehicle to a small transport vehicle when transporting the cargo by truck to a construction site. belongs to the technical field of

Therefore, this invention is used for mixed transportation from the loading platform of a carrier vehicle such as an 11-ton truck that can load multiple large heavy unit loads, and transfers one large heavy unit load to the loading platform of a small carrier vehicle such as a 4-ton truck. This is a device for transferring heavy unit loads that is equipped with rollers used when transporting pistons to the construction site. The carrier has a support body interposed on the loading platform, a jack for lifting the loading platform and the loading platform during transshipment, and a hanging body integrated with the support body. A large-heavy unit cargo transfer device comprising a connecting body, and a moving roller is provided on one or both of the supporting body and the connecting body to facilitate movement with respect to the loading platform. This is the idea.

<Prior art> As is well known, there has been an extremely strong demand for houses for civilian use and private residences in recent years, and in contrast to custom-built houses, so-called prefabricated houses and other house houses built in units are constructed in factories. It is a method of manufacturing, transporting to the construction site, installing and assembling it on site, and its cost, accuracy,
It is becoming widely used due to its many advantages such as shortened construction time.

Therefore, as mentioned above, houses and buildings using the unit construction method are manufactured in a factory and then transported to the site using the so-called land transportation method, and the units are loaded as large units with considerable weight. Therefore, truck transportation is generally used.

Therefore, construction sites for so-called civilian buildings and private residences, both in urban and rural areas, are located far from so-called arterial roads and industrial roads due to locational conditions. In many cases, roads are not well maintained, and therefore, the road conditions between the factory and the installation site are often not as good as they get closer to the installation site.

By the way, the cargo of such large and heavy units manufactured at the factory is quite heavy due to the specifications and restrictions of the unit, so the transportation cost cannot be ignored, and therefore,
Due to various conditions such as transportation efficiency issues, cost issues, and the fact that larger units are easier to construct on-site and shorter construction times, two or three units may be moved using a small carrier such as a 4-ton truck. It is much more effective to transport a large amount at once using a large transport vehicle such as an 11-ton truck than to transport multiple times.

However, due to the road conditions mentioned above, we transport the materials to the construction site using large-capacity vehicles such as 11-ton trucks whenever possible, and transport the materials from the bottleneck to the construction site by transferring them onto small-sized vehicles such as 4-ton trucks. The method of doing this has come to be adopted.

<Problem that the invention aims to solve> Therefore, for example, two large heavy unit loads are loaded from the factory onto a large transport vehicle such as an 11-ton truck and transported on the main road, and on a narrow road, a small transport vehicle such as a 4-ton truck is used. A mixed transportation method was adopted in which the vehicle was transferred to a car and transported to the construction site, and the 12th
As shown in the figure, when two large heavy unit cargoes 2 are loaded onto a large transport vehicle 1 of 11 tons at the time of factory shipment, for example, two large unit cargoes 2 are placed on each of the four corners as shown in Fig. 13. A support trolley 3 of various types is interposed and movable via rollers 4, 4, etc. provided at predetermined locations.
The support cart 3 is fixed to the cargo platform 6 by positioning the pin hole 5 of the carrier 6 and the pin hole 7 of the carrier 6 shown in FIG.
A fixing pin 8 is installed by screwing into the structure, and each large heavy unit load 2 is placed on the support truck 3 for mixed transportation on the main road. The transport vehicle 9 is caused to travel along with the large transport vehicle 1, and when the large transport vehicle 1 comes to a bottleneck where the large transport vehicle 1 cannot run, the small transport vehicle 9 is placed facing the rear of the large transport vehicle 1 as shown in FIG. are connected via a path board 10 and a jack 11,
The support truck 3 and the fixing pin 7 for the loading platform 6 are removed, and the large weight unit load 2 is transferred from the loading platform 6 of the large transportation vehicle 1 to the loading platform 13 of the small transportation vehicle 9 using the winch 12 of the small transportation vehicle, and then,
The small transport vehicle 9 carrying the large heavy unit load 2 was transported through a bottleneck to the construction site.

However, with the conventional transshipment method, first of all, large heavy machinery such as jacks and winches must be used, which has the disadvantage of requiring large-scale equipment, resulting in poor work efficiency and no improvement in efficiency. However, there is a disadvantage that the cost is higher, and
In order to transport each large heavy unit cargo 2 mounted on a support cart 3, the rollers 4, 4, . . .
The disadvantage was that it was easily damaged and required maintenance, inspection, and replacement.

In addition, the height is always increased by the amount of the support cart 3 interposed between the large heavy unit load 2 and the platform 6 of the large carrier 1, and the height is limited by the height of the large heavy unit load 2. Another problem was that the degree of freedom in designing the heavy unit load 2 was hindered.

In addition, the small transport vehicle 9 requires special modification of the transport vehicle in order to be equipped with a winch, etc., and the winch etc. interferes with the heavy unit load 2, which limits the space on the loading platform. However, there was a problem in that the size of the heavy unit load 2 was limited due to the design.

For example, as shown in Utility Model Application Publication No. 55-20330, hooks with holes for stabilization and lifting are provided by attaching hardware for support and jacking up to the four corners of large luggage. Although there are techniques, there are problems similar to those described above when transferring heavy unit cargo from a large transport vehicle to a small transport vehicle.

The purpose of this invention is to solve the problem of transshipment in the mixed transport of large transport vehicles and small transport vehicles for heavy unit loads based on the above-mentioned conventional technology, and to While taking full advantage of the potential advantages of mixed transport, transshipment can be carried out smoothly, there is no loss of freedom in the design of large-heavy unit loads, there is no need to modify transport vehicles, and maintenance, inspection and maintenance are easy. Excellent heavy-duty unit load transfer that is easy to use, free from breakdowns and damage, can be used repeatedly, has sufficient economic merit, and is easy to work with, benefiting the field of loading rack technology application in the transportation industry. The aim is to provide the equipment.

<Means/effects for solving the problems> In accordance with the above-mentioned purpose, the structure of this invention, which is based on the scope of the above-mentioned utility model registration claim, is to solve the above-mentioned problems by using units for prefabricated houses and large mechanical devices. When transporting large loads such as large units overland from the factory to the installation site, multiple units are placed on the loading platform of a large transport vehicle via a support at the corner of the loading platform at the time of shipment from the factory. On the other hand, one large heavy unit load is similarly placed on the loading platform of the small transport vehicle, and mixed transport is carried out along the main road to a bottleneck near the construction site, and when the bottleneck is reached, only the small transport vehicle First, the heavy unit load on the rack is carried to the construction site, and then the returning small carrier connects the loading platform with the loading platform of the large carrier via a road board, etc., and then loads it onto the carrier of the large carrier. A connecting body is connected and fixed to each support of the large heavy unit load that is being hung, and the supporting body is unfixed to the loading platform of the large transport vehicle, and the connecting body is The large weight unit load is lifted together with each support by jacking, and the connected small transport vehicle is lifted from the loading platform of the large transport vehicle via rollers provided on one or both of the connecting body and the supports. The heavy unit loads are transferred to the loading platform, and all of these operations are performed efficiently and smoothly by hand.The heavy unit loads transferred to the loading platform of the small carrier are operated in the opposite manner to the above operations. The connecting body is removed from each support, the supports are fixed to the loading platform of a small carrier, and the small carrier is smoothly transported through the bottleneck to the construction site, and then returned again to carry out these operations. Repeatedly, a large amount of heavy unit cargo can be transported and brought in by piston transport from a large carrier to a small carrier, and the large heavy unit cargo in the middle of transportation is simply placed on the loading platform via a support. The space on each loading platform is fully utilized to
In addition, the design of the size of heavy unit cargo, and
Technical measures have been taken to ensure that this does not become a constraint during manufacturing.

Incidentally, two large heavy unit cargoes 2, 2 are loaded onto each of the plurality of large transport vehicles 1, and one large heavy unit cargo 2 is loaded onto one small transport vehicle 9 to carry out multiple mixed transportation. That is, mixed transportation may be performed using several transport vehicles 1 and one small transport vehicle 9.

When the vehicle travels on the main road and reaches a bottleneck near the construction site, first, only the small transport vehicle 9 transports the single heavy unit load 2 to the construction site, unloads it, and returns. As shown in FIG.
A path plate 10 is provided between the carriers 1 and 3 to communicate with each other, and stands 11' and 11' support the rear ends of both carriers 6 and 13.

Therefore, the connecting body 15, the support body 16, and the sub-connecting body 17 are integrated. , each side roller 50 comes into contact with the side surface of the loading platform 6, thereby preventing rattling in the lateral direction.

Therefore, the large heavy unit load 2 was transferred to a small transport vehicle 9.
By manually pushing to the side, each roller 34
The heavy unit load 2 is transferred from the loading platform 6 of the large carrier vehicle 1 to the loading platform 13 of the small carrier vehicle 9 via the road board 10, as shown by the arrow in FIG.

In this process, the loading platform 6 of the large carrier 1
If the width of the loading platform 13 of the small transport vehicle 9 is different, the bolts 47 of the plate 45 of the sub-coupling body 17,
47 with respect to the elongated holes 46, 46, the sub-connecting body 1 can be attached to the holder 18 of the connecting body 15.
7 can be displaced laterally to adjust the contact of the side rollers 50 with the loading platform 13 of the small carrier 9.

The large heavy unit cargo 2 transferred to the small transport vehicle 9 in this manner is separated from the connecting body 15 and the sub-connecting body 17 by the above-mentioned operation and the reverse operation, and is lowered onto the loading platform 13 and moved to the stopper 37. is seated in the fixing hole 36, and the heavy unit load 2 is loaded onto the platform 13 of the small transport vehicle 9 in a sufficiently low state, and the bracket 42 of the support body 16 and the platform 13 are fixed with bolts, and the unit travels through the bottleneck. and went to the construction site,
After unloading the large heavy unit loads 2, the operator returns to the large conveyance vehicle 1 and repeats the above-mentioned operations, thereby making it possible to transport each large heavy unit load 2 with a piston.

Therefore, by performing such work, even if two large heavy unit loads 2, 2 are loaded onto each of a plurality of large transport vehicles 1 for mass transportation, only one small transport vehicle 9 is required. It is possible to efficiently transport large heavy unit loads 2 to the construction site.

Further, the embodiment shown in FIGS. 8 and 9 is a fork 2 in which the roller 34 of the connecting body 15 of the above-mentioned embodiment is omitted.
9' is placed inside the holder 18, while a recess 5 is formed on the outer surface of the flange 39 of the support body 16.
1 and screwed in the bolt 52, and by the relative protrusion of the fork 29' by the bolt 24 of the connecting body 15', the holder 15' is raised together with the support 16', as shown in FIG. With the heavy unit load 2 sufficiently elevated from the loading platform 6 of the large transport vehicle 1, the concave portion 5 of the flange 39 of the support 16'
1, the foot of a caster 54 having a roller 53 is attached and fixed with a bolt 52, and then,
By operating the bolt 24 in the reverse direction again, the large heavy unit load 2 is lowered together with the support 16', and the rollers 53 of the caster 54 are moved to the loading platform 6.
The carrier can be transferred from the loading platform 6 of the large carrier 1 to the loading platform 13 of the small carrier 9 by sitting on the carrier.

In this embodiment, the sub-coupling body 17 can be used in the same manner as in the previous embodiment.

Since the transshipment device 14 is used repeatedly, the roller 2 of the coupling body 15 may be accidentally damaged.
7 is damaged, the above-mentioned embodiments have the advantage of providing flexibility in use.

It goes without saying that the embodiment of this invention is not limited to the above-described embodiment, and various embodiments may be adopted, such as providing rollers for the loading platform on the side of the sub-coupling body.

In addition, it is applicable not only to heavy unit loads for prefabricated houses, but also to heavy unit loads such as machine tools in manufacturing factories.
It can also be applied when transporting heavy unit loads such as containers.

<Effects of the invention> As described above, according to this invention, when large quantities of heavy unit loads such as prefabricated housing units are efficiently transported by land to the construction site in large quantities, multiple heavy unit loads can be transported by large transport vehicle. While taking full advantage of the benefits of mixed transportation between large and small carriers, the transfer from the large carrier to the platform between the small carriers can be done manually without the use of large heavy machinery such as winches. It has the excellent effect of being easy to work with and can be done efficiently, and each unitizing jig of the transfer device is small,
It does not take any effort to store it, and since the space between the heavy unit load and the loading platform requires only a support, the space for the loading platform and the space of large and small carriers can be fully utilized. Therefore, there is a greater degree of freedom in the design size of heavy unit loads, and an excellent effect is produced that adds to the manufacturing efficiency.

In addition, during transportation, since no rollers are interposed between the heavy unit load and the loading platform, there is no damage to the rollers due to vibration, which improves the durability of the equipment and makes maintenance easier. This has the effect that there is almost no need for replacement, and therefore the device can be made smaller and the cost can be reduced due to its durability.

In addition, since there is no need to install a winch or the like on the large or small carrier as mentioned above, there is no need to modify the carrier, which also reduces costs and does not hinder the versatility of the carrier. It also has the effect that it does not occur.

Further, as mentioned above, since a winch or the like is not required on the loading platform of the transport vehicle, there is also the advantage of flexibility in that the transport vehicle can be used for other purposes as well.

In addition, as mentioned above, the transfer device can be made into a small unit, freed up, and disassembled, making it easy to store. When transporting, only one device needs to be stored, so it is easy to store and does not take up much space, and it also has the advantage of being able to be used repeatedly when transporting pistons.

Therefore, in this invention, support rollers for the top surface of the loading platform are attached to the supports provided at the corners of the heavy unit cargo, and side rollers for the sides of the supports are attached to the connecting body. , when transporting large heavy unit loads from a large transport vehicle to a small transport vehicle via a loading platform, it is not only possible to transport them extremely smoothly, but also prevents rattling during lateral transport, resulting in smooth vibration and rocking. The effect of being able to be transported is achieved.

In addition, since the connecting body is provided with a jack on the support body to adjust the height of the support roller with respect to the loading platform, the height of the support roller can be adjusted in the vertical direction when transporting a heavy unit load from a large carrier to a small carrier via the loading platform. Since it is possible to transport at an appropriate level by eliminating unexpected swings and vibrations, there is also the safety effect that there is no risk of heavy unit loads falling over during transport.

As mentioned above, it has a semi-permanent effect of being highly durable despite such frequent repeated use.
