[0022] Please see Figure 1 , Figure 2 and Figure 3 An embodiment of the present invention provides a connecting frame assembly, comprising an outer connecting frame 100, a tilting frame 200, a lifting frame 300, and a guide assembly 400. The tilting frame 200 is rotatably connected to the outer connecting frame 100, and the lifting frame 300 is slidably connected to the tilting frame 200 in a vertical direction. The lifting frame 300 includes two longitudinal beams 310 and two transverse beams 320, with each end of the two longitudinal beams 310 connected to one of the two transverse beams 320. The longitudinal beams 310 are provided with locking buckles 311 for lifting containers. The guide assembly 400 includes a slide rail 410 and rollers 420. The slide rail 410 is mounted on the tilting frame 200, and the rollers 420 are rotatably connected to the transverse beams 320. The rollers 420 abut against the slide rail 410 and are slidably connected to the slide rail 410 in a vertical direction.

[0023] The hanger 300 is connected to form a square frame structure by two longitudinal beams 310 and two transverse beams 320. The overall structure of the hanger 300 is relatively stable, making it easy to control the locking buckles 311 on the two longitudinal beams 310 to rise or fall synchronously, and the difficulty of coordinated lifting control is small. The hanger 300 is slidably connected to the tilting frame 200 in the vertical direction, and the rollers 420 connected to the hanger 300 are slidably connected to the slide rails 410 in the vertical direction, making the lifting and lowering of the hanger 300 on the tilting frame 200 more stable.

[0024] In some embodiments, see Figure 2 , Figure 3 and Figure 4 A blocking frame 210 is provided above the tilting frame 200 to restrict the upward movement of the crossbeam 320. A baffle 411 is provided at the lower end of the slide rail 410 to restrict the downward movement of the roller 420. When the hanger 300 moves to the uppermost position, the crossbeam 320 abuts against the blocking frame 210; when the hanger 300 moves to the lowermost position, the roller 420 abuts against the baffle 411. The blocking frame 210 and the baffle 411 limit the range of movement of the hanger 300 and ensure the smooth operation of the hanger 300.

[0025] In some embodiments, see Figure 2 , Figure 3 and Figure 4 The slide rail 410 is provided with a first buffer pad and a second buffer pad 412. The first buffer pad is located near the stop frame 210, and the second buffer pad 412 is located near the baffle 411. The first buffer pad has a first inclined surface, and the second buffer pad 412 has a second inclined surface 4121. The lower end of the first inclined surface is located near the slide rail 410, and the upper end of the second inclined surface 4121 is located near the slide rail 410. There is a gap between the roller 420 and the slide rail 410. When the crossbeam 320 abuts against the blocking frame 210, the first inclined surface guides the roller 420 to move from the slide rail 410 to the first buffer pad. The roller 420 abuts against the first buffer pad, and the first buffer pad fills the gap between the roller 420 and the slide rail 410, making the hanger 300 stable. When the roller 420 abuts against the baffle 411, the second inclined surface 4121 guides the roller 420 to move from the slide rail 410 to the second buffer pad 412. The roller 420 abuts against the second buffer pad 412, and the second buffer pad 412 fills the gap between the roller 420 and the slide rail 412, making the hanger 300 stable.

[0026] Four slide rails 410 are provided, corresponding to four rollers 420, and the four slide rails 410 are located at the four corners of the hanger 300. At one end of the length of the hanger 300, two slide rails 410 are located between two rollers 420, and the first buffer pad and the second buffer pad are located on the side of the slide rail 410 opposite to the other slide rail 410. When the crossbeam 320 abuts against the blocking frame 210, the first inclined guide roller 420 moves from the slide rail 410 to the first buffer pad. Both first buffer pads fill the gap between the roller 420 and the slide rail 410, so that the hanger 300 is in a taut state and the structure is more stable.

[0027] In some embodiments, see Figure 2 , Figure 3 and Figure 4 A mounting base 330 is connected to the crossbeam 320. The guide assembly 400 also includes a mounting plate 430. A roller 420 is rotatably connected to one end of the mounting plate 430. The mounting plate 430 is bolted to the mounting base 330. The mounting plate 430 is bolted to the mounting base 330, making it easy to install and remove.

[0028] In some embodiments, see Figure 2 , Figure 3 and Figure 4 The mounting plate 430 has an elongated slot 431. Bolts pass through the elongated slot 431 and are screwed onto the mounting base 330. The length of the elongated slot 431 is perpendicular to the guide of the slide rail 410. The elongated slot 431 on the mounting plate 430 makes the distance between the mounting plate 430 and the slide rail 410 adjustable, and also makes the distance between the roller 420 and the slide rail 410 adjustable.

[0029] In some embodiments, see Figure 2 , Figure 3 and Figure 4 A limiting plate 331 is provided at the end of the mounting base 330 away from the slide rail 410. The mounting plate 430 is located between the slide rail 410 and the limiting plate 331. The limiting plate 331 is provided with a threaded hole 3311 for bolts to pass through, and the threaded hole 3311 is provided corresponding to the mounting plate 430. The bolt passes through the threaded hole 3311 and abuts against the mounting plate 430. By rotating the bolt, the length of the bolt extending out of the limiting plate 331 is adjusted, thereby adjusting the distance between the mounting plate 430 and the slide rail 410.

[0030] In some embodiments, see Figure 2 , Figure 3 and Figure 4The system also includes a trailer assembly 500, which comprises a trailer beam 510, a pull rod 520, and a trailer drive cylinder 530. The two ends of the pull rod 520 are hinged to the tilting frame 200 and the trailer beam 510, respectively. The two ends of the trailer drive cylinder 530 are also hinged to the tilting frame 200 and the trailer beam 510, respectively. The hinge point between the pull rod 520 and the tilting frame 200 is located above the hinge point between the trailer drive cylinder 530 and the tilting frame 200. The trailer drive cylinder 530 moves the trailer beam 510 away from the tilting frame 200, facilitating the lifting frame 300 to rise and fall along the tilting frame 200. When the lifting frame 300 lifts the container, the trailer drive cylinder 530 pulls the trailer beam 510 closer to the tilting frame 200, causing the trailer beam 510 to abut against the container. When the tilting frame 200 tilts the container for unloading, the trailer beam 510 provides stable support for the container.

[0031] In some embodiments, see Figure 2 , Figure 3 and Figure 4 The trailer beam 510 is equipped with support pads 511, and the support points are used to support the container. The support pads 511 can prevent the trailer beam 510 from scratching the container.

[0032] In some embodiments, see Figure 2 , Figure 3 and Figure 4 A vibrator 512 is connected to the trailer beam 510. When the tilting frame 200 tilts the container for unloading, the vibrator 512 on the trailer beam 510 can provide vibration to ensure faster container unloading.

[0033] See Figure 1 , Figure 2 and Figure 3 A tilting lifting device according to an embodiment of this application includes a connecting frame assembly, a tilting drive assembly, and a lifting drive assembly. The tilting drive assembly connects a tilting frame 200 and an outer connecting frame 100, and is used to drive the tilting frame 200 to rotate. The lifting drive assembly is mounted on the tilting frame 200 and connected to a lifting frame 300, and is used to drive the lifting frame 300 to lift.

[0034] The hanger 300 is connected to form a square frame structure by two longitudinal beams 310 and two transverse beams 320. The overall structure of the hanger 300 is relatively stable, making it easy to control the locking buckles 311 on the two longitudinal beams 310 to rise or fall synchronously, and the difficulty of coordinated lifting control is small. The hanger 300 is slidably connected to the tilting frame 200 in the vertical direction, and the rollers 420 connected to the hanger 300 are slidably connected to the slide rails 410 in the vertical direction, making the lifting and lowering of the hanger 300 on the tilting frame 200 more stable.
