[0027] Reference Figure 1-Figure 3 , which is an embodiment of the utility model, provides an expandable transport device for large-scale cargo logistics, which includes:

[0028] The main body 100 includes a frame 101, and two sides of the top of the frame 101 are fixedly connected with slide rails 102, and two sets of slide rails 102 are arranged parallel to each other;

[0029] The slide assembly 200 has two sets of mirror images above the frame 101. The slide assembly 200 includes a slider 201, a support rod 202 and a placement table 203. The slider 201 has two sets. The two sets of sliders 201 are slidably connected to the two sets of slide rails 102 respectively. The support rod 202 is vertically fixedly connected to the top of the two sets of sliders 201. The placement table 203 is fixedly connected to the top of the four sets of support rods 202.

[0030] The expansion mechanism 300 includes a mounting plate 301, which is fixedly connected to the top of the frame 101 and arranged between the two sets of slide assemblies 200. A hydraulic cylinder 302 is fixedly connected to the top of the mounting plate 301, and an expansion platform 303 is fixedly connected to the top of the hydraulic cylinder 302. Two sets of connecting parts are matched between the expansion platform 303 and the two sets of primary wooden boards 204. The four sets of connecting parts are distributed in a rectangular shape. The connecting parts include a primary connecting slat 305, a secondary connecting slat 306 and a push-pull slat 307. The primary connecting slat 305 and the secondary connecting slat 306 are respectively fixedly connected to the bottom of the expansion platform 303 and the placement platform 203, and the two ends of the push-pull slat 307 are respectively hinged to the primary connecting slat 305 and the secondary connecting slat 306;

[0031] The expansion platform 303 has an isosceles trapezoidal cross section, and the two sets of placement platforms 203 can be assembled with the expansion platform 303 to form a slat-shaped platform.

[0032] In addition, three sets of casters 103 are fixedly connected to both sides of the bottom of the frame 101. The six sets of casters 103 are distributed in a rectangular shape. The casters 103 are used to facilitate the movement of the device.

[0033] In addition, the slide assembly 200 also includes a primary wooden board 204, which is embedded and fixed on the top of the placement platform 203. The expansion mechanism 300 also includes a secondary wooden board 304, which is embedded and fixed on the top of the expansion platform 303. The primary wooden board 204 and the secondary wooden board 304 are both used to increase friction and improve the stability of goods during transportation.

[0034] It should be noted that the hydraulic cylinder 302 is located at the bottom center of the expansion platform 303, and the hydraulic cylinder 302 is located in the middle of the frame 101 to ensure the structural stability of the device. The surfaces of the frame 101, the slider 201, the support rod 202, the placement platform 203 and the expansion platform 303 are all coated with anti-corrosion paint, which is used to improve the anti-corrosion performance of the device.

[0035] Working principle: The hydraulic cylinder 302 drives the expansion platform 303 to move up and down, and the expansion platform 303 drives each group of primary connecting strips 305 to move synchronously. The primary connecting strips 305 push and pull the two groups of placement platforms 203 through four groups of push-pull strips 307 and four groups of secondary connecting strips 306. When the expansion platform 303 moves upward, the two groups of placement platforms 203 move away from the expansion platform 303. When the top of the expansion platform 303 is flush with the two groups of placement platforms 203, Figure 1 As shown, the device is expanded. When the expansion platform 303 moves downward, the two sets of placement platforms 203 move toward the middle. When the two sets of placement platforms 203 are combined, as shown in FIG. Figure 3 As shown, the device cancels the expansion.
