[0022] Please see Figure 1 , Figure 2 and Figure 3This utility model discloses a positioning and guiding mechanism for positioning and guiding a container, enabling the container to smoothly connect with the lifting frame 500 of a tilting spreader. The tilting spreader includes a tilting frame 400 and a lifting frame 500. The tilting frame 400 includes a first inner frame 410 and a second inner frame 420, which are respectively installed at both ends of the lifting frame 500 along its length. The lifting frame 500 is slidably connected to the inner side of the tilting frame 400. The positioning and guiding mechanism includes two first guide components 100, which are respectively installed inside the first inner frame 410 and the second inner frame 420. Each first guide component 100 includes a guide drive component 110 and a first guide seat 120 connected to each other. The guide drive component 110 is a guide drive cylinder and is installed on the tilting frame 400. The guide drive component 110 is used to drive the first guide seat 120 to rise and fall, thereby causing the first guide seat 120 to extend from or retract into the tilting frame 400 from its lower end. The first guide seat 120 is provided with a first guide slope 121, and the distance between the two first guide slopes 121 gradually increases in the downward direction.

[0023] In normal operation, the guide drive assembly 110 drives the first guide seat 120 to retract into the tilting frame 400, improving space utilization and creating a compact structure. When the hanger 500 docks with the container, the two guide drive assemblies 110 drive the two first guide seats 120 to extend from the lower end of the tilting frame 400. The upper edge of the container is guided by the two first guide ramps 121 to the space between the first inner frame 410 and the second inner frame 420, avoiding interference between the container and the tilting frame 400 and ensuring that the container can dock smoothly with the hanger 500.

[0024] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The first guide assembly 100 also includes a guide cylinder 130 and a guide member 140. The guide cylinder 130 is mounted on the tilting frame 400, and the guide member 140 slides vertically through the guide cylinder 130. A first guide seat 120 is connected to the lower end of the guide member 140. The guide member 140 slides through the guide cylinder 130, and the first guide seat 120 is connected to the guide member 140. The guide member 140 guides the first guide seat 120, ensuring that the guide drive assembly 110 drives the first guide seat 120 to move stably up and down vertically.

[0025] In some embodiments, see Figure 1 , Figure 2 and Figure 3The first guide seat 120 includes a first connecting part 122 and two first guide parts 123. The two first guide parts 123 are respectively connected to the two ends of the first connecting part 122. The two first guide parts 123 are spaced apart along the width direction of the hanger 500, and each of the two first guide parts 123 is provided with a first guide ramp 121. The two first guide parts 123 are spaced apart along the width direction of the hanger 500, and the two first guide parts 123 guide the container simultaneously, increasing the force-bearing area of ​​the container, which can make the container bear force evenly and prevent the container from swaying left and right due to concentrated force.

[0026] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The positioning and guiding mechanism also includes a second guiding assembly 200, which includes a second guide seat 210 and a third guide seat 220. The second guide seat 210 and the third guide seat 220 are respectively installed on the hanger 500 at both ends along the width direction of the hanger 500. A second guide ramp 211 is provided on the side of the second guide seat 210 near the third guide seat 220, and a third guide ramp 221 is provided on the side of the third guide seat 220 near the second guide seat 210. The distance between the second guide ramp 211 and the third guide ramp 221 gradually increases in the downward direction. When the hanger 500 docks with the container, the upper edge of the container is guided by the second guide ramp 211 and the third guide ramp 221 to align with the hanger 500, ensuring that the container can dock smoothly with the hanger 500.

[0027] In some embodiments, see Figure 1 , Figure 2 and Figure 3 Two second guide components 200 are provided, spaced apart along the length of the jack 500. Two second guide seats 210 and two third guide seats 220 are respectively located at the four corners of the jack 500. When the container docks with the jack 500, the container is guided by the second guide seat 210 or the third guide seat 220 at each of its four corners, ensuring that the container is evenly pushed by the second guide components 200, thus guaranteeing a smooth docking between the container and the jack 500.

[0028] In some embodiments, see Figure 1 , Figure 3 and Figure 4The positioning and guiding mechanism also includes a third guiding assembly 300, which is mounted on the hanger 500. The third guiding assembly 300 includes a guide block 310 and an elastic element 320 connected to each other. The guide block 310 is hinged to the hanger 500 at its center. The lower end of the guide block 310 has a fourth guiding ramp 3111, which gradually moves downwards away from the center of the hanger 500. The elastic element 320 is used to move the lower end of the guide block 310 towards the center of the hanger 500. When the hanger 500 docks with the container, the elastic element 320 moves the lower end of the guide block 310 towards the center of the hanger 500, the fourth guiding ramp 3111 at the lower end of the guide block 310 guides the container towards the center of the hanger 500, and the elastic element 320 pushes the guide block 310 against the container, improving the stability of the hanger 500 when docking with the container.

[0029] In some embodiments, see Figure 1 , Figure 3 and Figure 4 The guide block 310 includes a second guide portion 311 and a second connecting portion 312 connected together. The second connecting portion 312 is hinged to the hanger 500 and connected to the elastic member 320. The second guide portion 311 is V-shaped, and a second guide ramp 211 is located at the lower end of the second guide portion 311. The second guide portion 311 is V-shaped with a protruding center to facilitate contact with the container. The second guide ramp 211 is located on the second guide portion 311 to facilitate guiding the container.

[0030] In some embodiments, see Figure 1 , Figure 3 and Figure 4 The thickness of the second guide portion 311 is greater than the thickness of the second connecting portion 312. The greater thickness of the second guide portion 311 increases the contact area between it and the container, ensuring a more uniform thrust. The smaller thickness of the second connecting portion 312 makes the hinged connection between it and the jack 500 more stable.

[0031] See in some embodiments Figure 1 , Figure 3 and Figure 4The third guide assembly 300 includes a limiting rod 330 and a baffle 340. The baffle 340 is mounted on the hanger 500 and has a through hole 341. The elastic element 320 includes a spring, which is sleeved on the limiting rod 330. One end of the limiting rod 330 is hinged to the guide block 310. An annular protrusion 331 is provided on the limiting rod 330 near the guide block 310. The other end of the limiting rod 330 slides through the through hole 341. The two ends of the spring abut against the annular protrusion 331 and the baffle 340, respectively. This confines the spring to the limiting rod 330, preventing it from easily falling off. When the container is docked with the jack 500, the container presses against the second guide part 311, causing the second connecting part 312 to rotate around the hinge point between the second connecting part 312 and the jack 500. The second connecting part 312 causes the limit rod 330 to move, and the annular protrusion 331 and the baffle 340 compress the spring, which stores energy. When the container is separated from the jack 500, the spring releases its elastic potential energy, pushing the annular protrusion 331 away from the baffle 340, and pushing the second connecting part 312 to rotate around the hinge point between the second connecting part 312 and the jack 500, causing the second guide part 311 to move closer to the center of the jack 500.

[0032] See Figure 1 , Figure 2 and Figure 3 According to an embodiment of this application, a tilting spreader includes a positioning and guiding mechanism, which is installed on a jack 500. The positioning and guiding mechanism is used to position and guide the container so that the container can be smoothly connected to the jack 500 of the tilting spreader.

[0033] In normal operation, the guide drive assembly 110 drives the first guide seat 120 to retract into the tilting frame 400, improving space utilization and creating a compact structure. When the hanger 500 docks with the container, the two guide drive assemblies 110 drive the two first guide seats 120 to extend from the lower end of the tilting frame 400. The upper edge of the container is guided by the two first guide ramps 121 to the space between the first inner frame 410 and the second inner frame 420, avoiding interference between the container and the tilting frame 400 and ensuring that the container can dock smoothly with the hanger 500.
