[0024] The fully-loaded van semi-trailer includes: a carriage body 1 and a top plate 13. The carriage body 1 includes a first section 2, a second section 3, and a third section 4. A traveling assembly 5 is also provided at the lower part of the carriage body 1. The traveling assembly 5 is respectively arranged at the lower parts of the first section 2 and the third section 4. The traveling assembly 5 includes traveling wheels 51 and wheel covers 52. A first closing door 6 is arranged on the second section 3, and a second closing door 7 is arranged on the third section 4. An expansion space 8 is arranged at the lower part of the second section 3. A lifting assembly 9 is arranged at the bottom of the expansion space 8. A lifting plate 10 is arranged on the lifting assembly 9. A limiting member 12 is arranged at the upper part of the carriage body 1. Sliding grooves 14 are opened on both sides of the top plate 13. The top plate 13 is slidably connected to the limiting member 12 through the sliding grooves 14. Two groups of driving devices 15 are arranged outside the second section 3, and an auxiliary pushing device 16 is arranged inside the first section 2. The driving device 15 is connected to the top plate 13, and the auxiliary pushing device 16 is connected to the top plate 13.

[0025] Goods are loaded in the first section 2, the second section 3, and the third section 4 of the carriage body 1. When transporting some goods that do not require the top plate 13 to block sunlight and rain, the top plate 13 can be retracted to both sides through the driving device 15 and the auxiliary pushing device 16, so as to stack goods as much as possible and increase the single-load capacity of the goods. In other cases, the top plate 13 remains stationary to provide protection for the goods; the expansion space 8, the lifting assembly 9, and the lifting plate 10 further increase the internal storage space.

[0026] The lifting assembly 9 includes a first rotating seat 91, a second rotating seat 92, and a hydraulic cylinder 93. The first rotating seat 91 is fixedly connected to the bottom of the expansion space 8, the second rotating seat 92 is fixedly connected to the lower surface of the lifting plate 10, and the hydraulic cylinder 93 is respectively rotatably connected to the first rotating seat 91 and the second rotating seat 92.

[0027] When transporting a large number of small-sized goods, the lifting plate 10 is controlled to move downward through the lifting assembly 9 to increase the size of the expansion space 8, so that more goods can be placed; when transporting some large-sized goods that can span the first section 2, the second section 3, and the third section 4, the lifting plate 10 is controlled to move upward through the lifting assembly 9 to provide support for them from the lower side.

[0028] A buffer part 11 is arranged in the expansion space 8. The buffer part 11 is arranged below the lifting plate 10. The buffer part 11 includes a first buffer plate 111, a second buffer plate 112, and a spring 113.

[0029] The spring 113 is located between the first buffer plate 111 and the second buffer plate 112, and when the goods are placed on the lifting plate 10, it reduces the impact on the lifting assembly 9.

[0030] The limiting member 12 includes a mounting seat 121, the mounting seat 121 is fixedly connected to the upper part of the carriage body 1, a slider 122 is arranged on the mounting seat 121, a stop block 123 is arranged on the slider 122, and the stop block 123 is located inside the chute 14.

[0031] The slider 122 is used to enable the top plate 13 to slide and retract to both sides of the carriage body 1, and the stop block 123 plays a limiting role.

[0032] The driving device 15 includes a third rotating seat 151, a first telescopic push rod 152 and a fixed seat 153. The third rotating seat 151 is fixedly connected to the outside of the second segment 3, the fixed seat 153 is fixedly connected to the top plate 13, and the first telescopic push rod 152 is rotatably connected to the third rotating seat 151 and the fixed seat 153 respectively.

[0033] When the first telescopic push rod 152 is started, with the assistance of the auxiliary pushing device 16, the top plate 13 is pulled from one end of the fixed seat 153, and through the cooperation of the slider 122 and the chute 14, it is retracted and gradually approaches the outer wall of the carriage body 1.

[0034] The auxiliary pushing device 16 includes a fourth rotating seat 161, a second telescopic push rod 162 and a fifth rotating seat 163. The fourth rotating seat 161 is fixedly connected to the inside of the first segment 2, the fifth rotating seat 163 is fixedly connected to the top plate 13, and the second telescopic push rod 162 is rotatably connected to the fourth rotating seat 161 and the fifth rotating seat 163 respectively.

[0035] The auxiliary pushing device 16 plays an auxiliary role in the process that the driving device 15 pulls the top plate 13, retracts it to the outside of the carriage body 1 and closes it against the outer wall of the carriage. When the second telescopic push rod 162 is started, it pushes the top plate 13 to rotate around the slider 122. During this process, the top plate 13 also slides through the chute 14, so as to retract it and gradually approach the outer wall of the carriage body 1.

[0036] The working principle of the full - load box - type transport semi - trailer provided by the present utility model is as follows:

[0037] The goods are loaded in the first section 2, the second section 3 and the third section 4 of the carriage body 1. When transporting some goods that do not require the top plate 13 to block sunlight and rain, the top plate 13 can be retracted to both sides through the driving device 15 and the auxiliary pushing device 16, so as to stack the goods as much as possible and increase the single carrying capacity of the goods. In other cases, the top plate 13 remains stationary to provide protection for the goods; the expansion space 8, the lifting assembly 9 and the lifting plate 10 further increase the internal storage space.

[0038] Compared with the related art, the full-load box-type transport semi-trailer provided by the present utility model has the following beneficial effects:

[0039] The expansion space 8, the lifting assembly 9 and the lifting plate 10 increase the flexibility of use of the internal storage space; when transporting some goods that do not require the top plate 13 to block sunlight and rain, the top plate 13 can be retracted to both sides of the carriage body 1 through the driving device 15 and the auxiliary pushing device 16, so as to stack the goods as much as possible and increase the single carrying capacity of the goods. In other cases, the top plate 13 remains stationary to provide protection for the goods.
