Description

Multipurpose Car Transport Trailer

technical field

The utility model relates to a transport trailer, in particular to a multipurpose vehicle transport trailer structure capable of adjusting the position of the upper and lower decks.

Background technique

The car transport trailer has a lower deck and upper decks to support the cars on each deck. The upper deck of most trailers can be raised slightly from a lower or loading position to a higher or transporting position. When the trailer upper deck is in the lower or loading position, the car is usually driven to the upper deck via an inclined ramp and attached deck section. The lower or loading position helps reduce the inclination of the loading ramp. When the upper load plate is full of cars, it will rise to a higher or transport position where there is sufficient clearance to load cars onto the lower plate.

A common disadvantage of this trailer design is the return trip, without the cargo, which must be transported separately since they can neither be fully folded nor loaded on top of another carrier. Also, today this trailer design does not transport cargo, which is usually transported by truck.

Detailed ways

As shown in Figures 1-11, the trailer 10 has an upper board 12 and a lower board 14 respectively, which are separately suitable for carrying cars or light trucks or both are used simultaneously. The trailer 10 is specially designed for road transportation when there is motor traction When the car is towing it (not shown in the picture).

The load plate 14 has a forwardly raised front end 14a, a rigid central region 14b connected to side supports 34, wheel members 14c and rigid ends 14d.

The front end 14a of the trailer 10 may be mounted on a fifth wheel (not shown) of the tractor with the post 18 nested on the front end 14a. Front end 14a is pivoted with a swash plate 20 which is driven by hydraulic pressure to rotate. The position of FIGS.

The upper carrier plate 12 has a rigid central region 12a connected to side brackets 12a', a rear carrier plate portion 12c connected by a hinged middle member 12b. The central section 12a has a forwardly extending sloping plate 26 which is telescoping from the central section 12a. The sloping plate 26 is coupled to the column 18. When the sloping plate 26 is fully extended, the column 18 is in a vertical position.

In Fig. 4, the upper carrier plate 12 is shown in its lowermost or nested position, with the central region 12a and the hinged middle member 12b arranged substantially coplanar with respect to the horizontal. The central section 12a is mounted adjacently to the intermediate main part 14b on the loading plate 14 . The hinged part 12b covers and nests into the wheel part 14c. This provides a flat deck for hauling goods during the first leg of the transport vehicle's journey, and vice versa, on the return journey. When the double-layer carrier trailer mode is converted to the flat carrier trailer mode, the upper carrier board is nested into the lower carrier board to provide a flat carrier carrier trailer as shown in Figure 8.

As shown in Figures 1, 5 and 6, through a considerable number of hydraulic cylinders, the corresponding length of each pillar can be selectively telescopically adjusted, and each pillar can be fastened in a telescopic position so as to maintain extension when the hydraulic cylinder loses water pressure state.

In operation, it is preferred that the opposite ends of the central region 12a of the upper carrier plate 12 continue to rise. First, the front end of the central region 12a rises, and then the end of the central region 12a rises. Again, the connectable rear panel part 12c and the hinged middle part 12b are raised. This sequence prevents bundling and twisting of components and allows inspection and determination of correct installation of components. When the state of the middle part 12b rises and is installed between the wheel parts 14c of the loading plate 14, it is supported by a fastening telescopic support 28 with a fixed length that is desired.

In order to achieve orderly operation, a pair of horizontally opposite, longitudinally arranged hydraulic cylinders 30 are fixedly positioned on each side of the outside of the trailer 10 and midway between the parallel side brackets 34 of the loading plate 14 . As shown in FIGS. 2 and 3 , the guide member 36 is mounted on the side bracket 34 . When the front hydraulic cylinder 30a of the pair of hydraulic cylinders 30 is extended, the front telescoping strut 40a rotates to a generally vertical state. Likewise, when the rear hydraulic cylinder 30b is extended, the rear telescoping strut 40b rotates to a vertical state. The lower ends of the struts 40 a and 40 b are hinged on a bracket 42 which is slidably mounted on the guide 36 .

The upper ends of the pillars 40a and 40b are installed on the corners of the central area 12a of the upper carrier plate 12. When rotated to the vertical position, the pillars 40a and 40b are fastened to the lower plate 14, and if the water pressure of the hydraulic cylinder 30 leaks, it can prevent In the event of unintentional rotation of the struts, once rotated to the vertical-up position, as shown in FIG.

As shown in Figure 2, 3, 6a, by hydraulic cylinder 44, front and rear telescopic struts 40a and 40

b may extend further vertically. As shown in Figure 6, this increases the clearance between the upper and lower plates.

Parts 41a and 41b are fastened to their respective posts 40a and 40b by inserting nails 43 through holes 43a.

When the slant plate 26 is fully extended, the slant plate 26 is mounted on the vertical column 18 . The inclined plate 26 is normally telescopically nested in the front end of the central area 12 a of the upper plate 12 .

The hinged rear panel part 12c is rotated according to the operation of the hydraulic cylinder 48 . The hydraulic cylinder 48 is mounted on the rear post 50 .

The rear post 50 is telescopic. The telescoping member 50a can be snapped onto the support sleeve 50b to secure the carrier plate 12c in its position, for example, a nail will be inserted into the hole and passed through the sleeve 50b and the separation hole 52 to prevent accidental collapse. As shown in FIG. 5 , the attachment of the load deck 16 to the rear deck member 12c provides continuous vehicle access from the road surface to the upper deck 12 .

Loading of the lower deck 14 requires that the upper deck 12 and the attachable rear deck section 12 be raised sufficiently to unload vehicles that must be driven onto the lower deck 14 . This is accomplished by actuation of hydraulic cylinders 44 and 48 which are compressed with struts 40a, 40b and 50, respectively.

As shown in FIG. 7 , when the loading of the loading board 14 is completed, the loading board 12 may be lowered to a suitable transportation height to lower the center of gravity of the trailer and keep the goods stable when running at high speed.

When the upper deck 12 portion is in the lowest position, that is to say, coupled or nested on the floor member, as can be seen in Figures 4 and 8, as described above, the trailer is transformed into a flat deck trailer (The flat deck mode referred to here) can transport heavy equipment or building materials. This substantially increases the functionality of the previous single-function trailer. Furthermore, since the sides of the trailer 10 and the upper deck 12 are in their lowest positions, Makes it possible to place one or more trailers on the return journey.

In the flat-bed trailer mode, the central area 12a of the trailer can bear heavy loads because the side supports of the upper plate 12 rest on the side supports of the lower plate 14, so that the load is distributed along the length of the central area of the lower plate 14, through The combined outlets of the upper and lower boards increase the carrying capacity of the central area.

The side supports of the upper carrier plate 12 have sufficient height, so when the upper carrier plate 12 is lowered, the apex of the central region 12a of the upper carrier plate 12 is coplanar with the wheel covering portion 12b of the upper carrier plate 12, and the weight of the wheel covering portion 12b bears Download plate wheels distribute the load. The heavy loading capacity of the flatbed trailer is achieved by extending the combined length of the central region 12a and the wheel covering portion 12b.

As can be seen in FIG. 9, the upper deck 12 and lower deck 14 of the trailer 10, or goods and equipment that can be loaded on pallets or in containers, are loaded to a convenient height suitable for road travel at the lower deck 14, and the upper deck 12 or can be appropriately reduced.
