Technical Field
[0001] This utility model relates to the technical field of gooseneck low flatbed semi-trailers, and in particular to a gooseneck low flatbed semi-trailer. Background Technology
[0002] The gooseneck low-bed semi-trailer is a semi-trailer specifically designed for transporting heavy goods. It is mainly used for transporting large machinery and heavy cargo. Its low-bed structure design can effectively reduce the height of the loading platform, making it easier to load oversized and overheight goods. The gooseneck design makes the loading surface and center of gravity lower, improving the stability and safety of transportation.
[0003] When workers need to transport goods, they connect the low-bed semi-trailer to the tractor and place the goods on it. However, existing low-bed semi-trailers generate significant centrifugal force during turns, causing the goods on them to slide laterally, which in turn leads to instability when transporting goods. Summary of the Invention
[0004] The purpose of this utility model is to solve the problem of instability that occurs when low-bed semi-trailers transport goods in the prior art, and to propose a gooseneck low-bed semi-trailer.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a gooseneck low-flatbed semi-trailer, comprising a transport platform, wheels mounted on the lower surface of the transport platform, and limiting devices provided on both sides of the transport platform. Each limiting device includes a limiting plate placed on the upper surface of the transport platform. Support sleeves are fixedly connected to both sides of the transport platform. A rotating block is fixedly connected to one side of the limiting plate. A rotating shaft is fixedly connected to the surface of the rotating block and rotatably connected to the interior of the support sleeve. A guide sleeve is fixedly connected to one side of the support sleeve. A storage sleeve is fixedly connected to the outer surface of the rotating block. An insert is slidably connected to the interior of the guide sleeve and inserted into the interior of one of the storage sleeves. An anti-slip component is provided inside the insert. The anti-slip component includes a limiting pin, which is slidably connected to the interior of the insert and inserted into the interior of the guide sleeve. A tension spring is fixedly connected between the limiting pin and the insert. The tension spring is located on one side of the transport platform. The limiting pin can cooperate with the tension spring and the insert to prevent the insert from sliding away from the storage sleeve.
[0006] Preferably, the surface of the limiting plate is provided with a shielding device, the shielding device includes a placement box, the placement box is fixedly connected to the surface of one of the limiting plates, and a storage rod is rotatably connected inside the placement box. The placement box can cooperate with one of the limiting plates to achieve the purpose of supporting the placement box.
[0007] Preferably, a covering cloth is fixedly connected to the surface of the storage rod, and one end of the covering cloth is placed on the surface of another limiting plate. The covering cloth can cooperate with the storage rod to achieve the purpose of storing the covering cloth.
[0008] Preferably, one end of the shielding cloth is rotatably connected to a plurality of second positioning rods, one of which is internally threaded to another limiting plate, and the other second positioning rods are internally threaded to the transport table. The second positioning rods can cooperate with another limiting plate and the shielding cloth to achieve the purpose of restricting the shielding cloth.
[0009] Preferably, a positioning hole is provided on one side of the placement box, and a first positioning rod is inserted and connected inside the positioning hole. The positioning hole can cooperate with the placement box to achieve the purpose of storing the first positioning rod.
[0010] Preferably, one end of the storage rod is fixedly connected to a rotating disk, and the first positioning rod is threadedly connected to the inside of the rotating disk. The rotating disk can cooperate with the storage rod and the first positioning rod to restrict the rotation of the rotating disk.
[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0012] In this invention, by setting a limiting device, when the worker needs to limit the goods, the worker rotates the limiting plate, which drives the rotating block, which in turn drives the rotating shaft to rotate 90 degrees on the support sleeve. When the limiting plate abuts against the surface of the transport platform, the worker pushes the insert, and the guide sleeve guides the insert, which is then inserted into one of the storage sleeves. The worker then releases the limiting pin, pulls the spring to pull the limiting pin, and the limiting pin is inserted into the guide sleeve. By setting the limiting device, the goods can be effectively limited, preventing the goods on the low-bed semi-trailer from sliding laterally, thereby reducing the instability of the low-bed semi-trailer when transporting goods.
[0013] In this invention, by setting up a shielding device, when the worker needs to protect the goods, the worker rotates the rotating disk, which drives the storage rod, releasing the shielding cloth. The worker adjusts the shielding cloth to cover the goods. When the shielding cloth extends to the designated position, the worker rotates the first positioning rod, which extends and inserts into the positioning hole. The worker then rotates the second positioning rod, and multiple second positioning rods are respectively connected to the internal threads of another limiting plate and the transport platform. By setting up the shielding device, it is possible to effectively protect the goods for the worker, avoiding the goods from being exposed to rain or direct sunlight for a long time during transportation, thereby improving the lifespan of the goods.

[0022] The following section will explain the specific settings and functions of the limiting device 3 and the blocking device 4.
[0023] In this embodiment: the limiting device 3 includes a limiting plate 31, which is placed on the upper surface of the transport platform 1. Support sleeves 33 are fixedly connected to both sides of the transport platform 1. A rotating block 35 is fixedly connected to one side of the limiting plate 31. A rotating shaft 32 is fixedly connected to the surface of the rotating block 35. The rotating shaft 32 is rotatably connected to the inside of the support sleeve 33. A guide sleeve 36 is fixedly connected to one side of the support sleeve 33. A storage sleeve 34 is fixedly connected to the outer surface of the rotating block 35. An insert 37 is slidably connected inside the guide sleeve 36. The insert 37 is inserted into the inside of one of the storage sleeves 34. An anti-slip component is provided inside the insert 37.
[0024] Specifically, the anti-slip component includes a limiting pin 39, which is internally slidably connected to the insert 37 and internally inserted into the guide sleeve 36. A pull spring 38 is fixedly connected between the limiting pin 39 and the insert 37. The pull spring 38 is located on one side of the transport platform 1. The limiting pin 39 can cooperate with the pull spring 38 and the insert 37 to restrict the insert 37 from sliding out of the storage sleeve 34.
[0025] Specifically, the surface of the limiting plate 31 is provided with a blocking device 4, which includes a placement box 42. The placement box 42 is fixedly connected to the surface of one of the limiting plates 31, and a storage rod 43 is rotatably connected inside the placement box 42.
[0026] In this embodiment, the placement box 42 can cooperate with one of the limiting plates 31 to support the placement box 42.
[0027] Specifically, a cover cloth 41 is fixedly connected to the surface of the storage rod 43. One end of the cover cloth 41 is placed on the surface of another limiting plate 31. The cover cloth 41 can cooperate with the storage rod 43 to achieve the purpose of storing the cover cloth 41.
[0028] In this embodiment: one end of the shielding cloth 41 is rotatably connected to a plurality of second positioning rods 47, one of which is internally threaded to another limiting plate 31, and the other second positioning rods 47 are internally threaded to the transport table 1. The second positioning rods 47 can cooperate with another limiting plate 31 and the shielding cloth 41 to achieve the purpose of restricting the shielding cloth 41.
[0029] Specifically, a positioning hole 44 is provided on one side of the placement box 42, and a first positioning rod 45 is inserted and connected inside the positioning hole 44.
[0030] In this embodiment, the positioning hole 44 can cooperate with the placement box 42 to achieve the purpose of storing the first positioning rod 45.
[0031] Specifically, one end of the storage rod 43 is fixedly connected to the rotating disk 46, and the first positioning rod 45 is internally threadedly connected to the rotating disk 46.
[0032] In this embodiment, the rotating disk 46 can cooperate with the storage rod 43 and the first positioning rod 45 to restrict the rotation of the rotating disk 46.
[0033] Working principle: By setting the limiting device 3, when the worker needs to limit the goods, the worker rotates the limiting plate 31. The limiting plate 31 drives the rotating block 35, and the rotating block 35 drives the rotating shaft 32 to rotate 90 degrees on the support sleeve 33. When the limiting plate 31 abuts against the surface of the transport platform 1, the worker pushes the insert 37. The guide sleeve 36 guides the insert 37, and the insert 37 is inserted into one of the storage sleeves 34. The worker releases the limiting pin 39, pulls the spring 38 to pull the limiting pin 39, and the limiting pin 39 is inserted into the guide sleeve 36. By setting the limiting device 3, the goods can be effectively limited, avoiding the lateral sliding of goods on the low flatbed semi-trailer, thereby reducing the risk of accidents when transporting goods. To address the instability issue, a shielding device 4 is installed. When workers need to protect the goods, they rotate a rotating disk 46, which drives a storage rod 43. The storage rod 43 releases a shielding cloth 41. The worker adjusts the shielding cloth 41 to cover the goods. When the shielding cloth 41 extends to the designated position, the worker rotates a first positioning rod 45, which extends and inserts into a positioning hole 44. The worker then rotates a second positioning rod 47. Multiple second positioning rods 47 are respectively connected to the internal threads of another limiting plate 31 and the transport table 1. By installing the shielding device 4, workers can effectively protect the goods and avoid them being exposed to rain or direct sunlight for extended periods during transportation, thereby extending the lifespan of the goods.
