[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0032] Please see Figure 1 - Figure 7 As shown, the present invention is a scrap steel trailer, including a tractor 1 and a connecting frame 7. The connecting frame 7 is installed on a movable cargo box, which facilitates the insertion of the gooseneck 3 into the connecting frame 7. The tractor 1 drives the cargo box to move and load and unload goods. A lifting platform 2 is installed on the tractor 1. The top of the lifting platform 2 is rotatably installed with the gooseneck 3. The gooseneck 3 is inserted into the connecting frame 7, so that the gooseneck 3 drives the connecting column 8 and the connecting ring 9 to engage and connect. This is convenient for matching multiple cargo boxes with one vehicle, which helps to improve the utilization rate of the trailer. The connecting frame 7 is fixedly installed with the connecting ring 9 on one side near the gooseneck 3. The connecting columns 8 are fixedly installed on both sides of the gooseneck 3 near the connecting ring 9. The connecting ring 9 is sleeved on the connecting column 8. The gooseneck 3 is provided with a compression component 4.
[0033] The extrusion assembly 4 includes a mounting groove 41 on the bottom surface of the lifting platform 2 near the connecting frame 7. Rectangular through holes 42 are provided on both sides of the mounting groove 41. A bidirectional lead screw 43 is rotatably mounted inside the mounting groove 41. Moving blocks 44 are threaded through the bidirectional lead screw 43 near both ends. The bidirectional lead screw 43 extrudes a rotating plate 45 via the moving blocks 44, causing the rotating plate 45 to lift a top block 47, which slides within the rectangular through holes 42. This causes the top block 47 to drive a friction strip 49 to tightly adhere to the inner wall of the connecting frame 7. The friction strip 49 increases the friction between the top block 47 and the inner wall of the connecting frame 7. Rotating plates 45 are rotatably mounted on the side of each moving block 44 near the rectangular through holes 42, and a top block 47 is rotatably mounted between the two rotating plates 45. A motor 410 is fixedly mounted on the side of the gooseneck 3 near the tractor 1. The output end of the motor 410 slides... The rotating plate 45 has an oblique through-hole 46, and a stabilizing rod 48 is slidably installed in the rectangular through-hole 42. The rotating plate 45 has an oblique through-hole 46, and a stabilizing rod 48 is slidably installed in the oblique through-hole 46. The two ends of the stabilizing rod 48 are fixedly installed in the mounting groove 41. The stabilizing rod 48 plays the role of stabilizing and limiting the rotating plate 45. A friction strip 49 is fixedly installed on the side of the top block 47 away from the oblique through-hole 43. There are multiple friction strips 49, which can increase the friction between the side of the gooseneck 3 and the connecting frame 7, facilitate flexible adjustment, improve the flexible adjustment capability of the gooseneck 3 installation, improve the firmness of the connection of the gooseneck 3, improve the safety and stability of the device, and minimize the possibility of the gooseneck 3 and the connecting frame 7 separating during transportation. This also improves the flexibility and applicability of the tractor 1.
[0034] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, a clamping assembly 5 is provided on the gooseneck 3. The clamping assembly 5 includes sliding grooves 51 on both sides of the gooseneck 3. An electric telescopic rod 52 is fixedly installed on the inner wall of the sliding groove 51. A slider 53 is fixedly installed on the end of the electric telescopic rod 52 near the connecting post 8. The electric telescopic rod 52 drives the slider 53 to slide in the sliding groove 51, so that the slider 53 drives the arc plate 54 to compress and stabilize the connecting ring 9, thus minimizing the possibility of the connecting ring 9 and the connecting post 8 separating. An arc plate 54 is fixedly installed on the side of the slider 53 away from the sliding groove 51. A rubber pad 55 is fixedly installed on the side of the arc plate 54 near the connecting post 8. The rubber pad 55 increases the friction between the arc plate 54 and the connecting ring 9. A balance bar is slidably installed through the slider 53. 56. The two ends of the balance bar 56 are fixedly installed on the inner wall of the slide groove 51. The balance bar 56 plays the role of balancing and stabilizing the slider 53. The side of the arc plate 54 away from the rubber pad 55 is fixedly installed with a sliding plate 58. The support plate 57 is fixedly installed at an angle between the sliding plate 58 and the arc plate 54. The support plate 57 plays the role of supporting and stabilizing the arc plate 54. One side of the sliding plate 58 slides and fits against the side of the gooseneck 3. The sliding plate 58 serves as the bottom plate of the support plate 57, which helps to increase the support stability of the support plate 57. Under the drive of the electric telescopic rod 52, the slider 53 makes the support plate 57 further clamp and stabilize the connection between the connecting ring 9 and the connecting column 8, which helps to improve the clamping capacity of the device and improve the safety and stability of the device.
[0035] Please see Figure 1 and Figure 3As shown, a positioning component 6 is provided on the connecting frame 7. The positioning component 6 includes a fixing plate 61 fixedly installed on the top of the connecting frame 7. The fixing plate 61 increases the connection area between the connecting frame 7 and the cargo box. A positioning groove 62 is opened on the top surface of the fixing plate 61. A bidirectional screw 65 is rotatably installed in the positioning groove 62. A clamping plate 63 is threaded through the bidirectional screw 65 near both ends. The bidirectional screw 65 drives the clamping plate 63 to clamp and stabilize the connecting parts of the cargo box. A knob 68 is fixedly installed on one side of the fixing plate 61. The knob 68 drives the bidirectional screw 65 to rotate in the positioning groove 62. The rotation shaft of the knob 68 slides through the positioning groove 62 and is fixedly installed on the bidirectional screw 65. A friction pad 64 is fixedly installed on the opposite side of the clamping plate 63. The friction pad 64 increases the connection between the clamping plate 63 and the cargo box. To reduce friction between the connecting parts, a sliding roller 67 is rotatably mounted on the side of the fixed plate 61 away from the connecting frame 7. The sliding roller 67 reduces friction between the connecting parts of the cargo box and the fixed plate 61, facilitating the positioning and adjustment of the cargo box. A guide rod 66 is slidably mounted through the clamping plate 63, with both ends of the guide rod 66 fixedly mounted on the inner wall of the positioning groove 62. The guide rod 66 guides and stabilizes the clamping plate 63. Multiple bolt holes 69 are provided on the fixed plate 61, and bolts are installed in the bolt holes 69 to facilitate the fixing of the cargo box to the fixed plate 61. This facilitates the installation and disassembly of the connecting frame 7 and the cargo box, as well as subsequent replacement and maintenance. It also facilitates the positioning and clamping of the cargo box, improving the positioning and clamping capabilities of the device, increasing the efficiency of device installation and disassembly, and improving the efficiency of device maintenance.
[0036] The working principle of this invention is as follows: When using the device, first install the connecting frame 7 at the bottom of the cargo box, then turn the knob 68 to make the rotating shaft of the knob 68 drive the bidirectional screw 65 to rotate in the positioning groove 62, causing the bidirectional screw 65 to drive the clamping plate 63 to move relative to each other in the positioning groove 62, causing the clamping plate 63 to slide on the guide rod 66, causing the clamping plate 63 to drive the friction pad 64 to squeeze the cargo box and move it on the fixing plate 61 under the action of the sliding roller 67, then the clamping plate 63 clamps and stabilizes the cargo box, and then the bolts are inserted into the bolt holes 69 to fix the cargo box. The connecting frame 7 is not frequently disassembled from the cargo box. Then the tractor 1 is started to drive the gooseneck 3 into the connecting frame 7, so that the connecting column 8 moves below the connecting ring 9. Then the lifting platform 2 is started to lift the gooseneck 3, so that the gooseneck 3 drives the connecting column 8 and the connecting ring 9 to adhere to each other. Simultaneously, the gooseneck 3 lifts the connecting frame 7 and the cargo box, and then the electric telescopic rod 52 is activated, causing the slider 53 to slide in the slide groove 51. The slider 53 slides on the balance bar 56, causing the slider 53 to drive the arc plate 54 and the rubber pad 55 to squeeze and clamp the connecting ring 9 on the connecting column 8. At the same time, the motor 410 is activated, causing the output end of the motor 410 to drive the bidirectional lead screw 43 to rotate in the mounting groove 41. The bidirectional lead screw 43 drives the moving block 44 to move relative to each other, and the moving block 44 squeezes the rotating plate 45 relative to each other. The rotating plate 45 fixes the top block 47 with a rectangular through hole 42, causing the top block 47 to drive the friction strip 49 to fit tightly against the inner wall of the connecting frame 7. At the same time, the waist-shaped through hole 46 on the rotating plate 45 slides on the stabilizing bar 48. Then the tractor 1 is activated, causing the tractor 1 to move the cargo box through the gooseneck 3 to load and unload goods.
[0037] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
