[0020] like Figure 1 , Figure 2 , Figure 3 As shown, a special trailer for road transport tandem includes a trailer body 1, a saddle 2 is fixedly connected to the rear side of the trailer body 1 by bolts, the front side and the rear side of the saddle 2 are respectively fitted with first limit assemblies, and the two first limit assemblies can have a limiting effect on the front side and the rear side of the saddle 2, and the left side of the saddle 2 is fitted with a second limit assembly, and the second limit assembly can have a limiting effect on the left side of the saddle 2, and the first limit assembly and the second limit assembly are respectively fixedly mounted on the trailer body 1;

[0021] The right side of the saddle 2 is movably connected with an adjustment limit assembly, which can be adjusted and limited after the saddle 2 is connected to the pin shaft, and the adjustment limit assembly can limit the right side of the saddle 2, and the adjustment limit assembly is fixedly installed on the trailer body 1.

[0022] During use, the two first limiting components can be used to limit the front and rear sides of the saddle 2, and the second limiting component can be used to limit the left side of the saddle 2. At the same time, the limiting components can be flexibly adjusted to perform limiting functions, thereby achieving limiting functions on the four sides of the saddle 2.

[0023] The first limiting assembly includes a fixing plate 3, a first limiting plate 5 and a first connecting plate 4. The first connecting plates 4 are fixed to both sides of the bottom of the fixing plate 3. The first connecting plates 4 are fixed with threaded holes, and locking bolts are screwed into the threaded holes. The first limiting plate 5 is fixed to the side of the top of the fixing plate 3. The first limiting plate 5 is arranged opposite to the side of the saddle 2, and a rubber plate is fixed to the side of the first limiting plate 5.

[0024] During use, the fixing plate 3 is installed and positioned by using the locking bolts threaded in the threaded holes on the first connecting plate 4, thereby ensuring that the first limiting plate 5 is in contact with the side of the saddle 2 for limiting effect. At the same time, because a rubber plate is fixed to the side of the first limiting plate 5, damage to the side of the saddle 2 can be prevented during the limiting effect.

[0025] The second limiting assembly includes a second limiting plate 6 and a second connecting plate 7. The second limiting plate 6 is arranged opposite to the side of the saddle 2. A rubber plate is fixed to the side of the second limiting plate 6. The bottom of the second limiting plate 6 is fixedly connected to the second connecting plate 7. A key-shaped through hole is fixed on the second connecting plate 7, and a locking bolt is screwed into the key-shaped through hole.

[0026] During use, the second limit plate 6 is installed and positioned by using the locking bolt threaded in the key-shaped through hole on the second connecting plate 7, ensuring that the second limit plate 6 contacts the side of the saddle 2 for limiting the position, and a key-shaped through hole is fixed on the second connecting plate 7, which makes it easy to adjust the installation position of the second connecting plate 7 and ensure that the second limit plate 6 contacts the side of the saddle 2.

[0027] The adjustment limit assembly includes a trapezoidal block 8 and a third limit plate 11. The trapezoidal block 8 is arranged at the lower end of the slideway of the saddle 2. An electric push rod 9 is fixedly connected to the bottom of the trapezoidal block 8. The electric push rod 9 is fixedly connected to the trailer body 1 through a connecting plate. The electric push rod 9 can push the trapezoidal block 8 into the slideway of the saddle 2.

[0028] During use, because the connecting pin needs to be inserted into the saddle 2 through the slide of the saddle 2, so as to realize the mutual connection of the trailers, when the connecting pin is inserted into the saddle 2 through the slide of the saddle 2, the electric push rod 9 is started, so that the trapezoidal block 8 can be put into the slide of the saddle 2, so that the connecting pin can be auxiliary limited to a certain extent.

[0029] The two sides of the bottom of the side end of the trapezoidal block 8 are fixedly connected to the third limit plate 11 through the connecting frame 10 respectively. The third limit plate 11 is slidably arranged in the slide groove, and the slide groove is fixed on the trailer body 1. The third limit plate 11 is arranged on the side of the saddle 2. The distance between the connecting frame 10 and the top surface of the trapezoidal block 8 is greater than the distance between the trapezoidal block 8 and the slideway of the saddle 2. A rubber plate is fixed to the side of the third limit plate 11;

[0030] During use, when the trapezoidal block 8 is driven by the electric push rod 9, the third limiting plate 11 will also slide out of the slide groove, and the third limiting plate 11 will contact the side surface of the saddle 2 to produce a limiting effect.
