[0021] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model is further described below in conjunction with embodiments.

[0023] Example: Refer to Figures 1 to 3 A low-bed semi-trailer with a protective function comprises a low-bed semi-trailer body 1. The low-bed semi-trailer body 1 is an existing well-known technology, and the specific structure and working principle thereof will not be described in detail herein.

[0024] The low-bed semi-trailer body 1 also includes a plurality of fixed columns 2 arranged at the upper end of the low-bed semi-trailer body 1, and the fixed columns 2 are arranged at the four corners of the low-bed semi-trailer body 1, and a plurality of fixed protective rods 3 are fixedly arranged between the fixed column 2 located at the right rear corner and the two adjacent fixed columns 2. By arranging four fixed columns 2 at the four corners of the low-bed semi-trailer body 1 and protective rods between adjacent fixed columns 2, a fence is formed around the low-bed semi-trailer body 1 to protect and shield the cargo on the low-bed semi-trailer body 1.

[0025] An L-shaped groove 5 is provided on the fixed column 2 located at the left front corner, and the L-shaped groove 5 is slidably connected to a mobile protection component. Specifically, the mobile protection component includes an L-shaped block 7 slidably connected to the L-shaped groove 5, and both ends of the L-shaped block 7 are fixedly connected to multiple mobile protection rods 9, and the other ends of the multiple mobile protection rods 9 are commonly fixedly connected to a guide block 8, wherein two diagonally arranged fixed columns 2 are provided with guide grooves 4, and the guide grooves 4 are slidably connected to the guide blocks 8. By setting the guide grooves 4 and the guide blocks 8 to slide in cooperation, the mobile protection rods 9 can be limited to ensure the stability of the mobile protection rods 9, and the sliding of the mobile protection rods 9 can also be guided to ensure the smoothness of the sliding of the mobile protection rods 9.

[0026] A driving assembly is also provided on the fixed column 2 located at the left front corner. Specifically, the driving assembly includes a mounting plate 10 fixedly provided on the fixed column 2 at the left front corner, and a rotating motor 11 is fixedly installed on the mounting plate 10. The rotating motor 11 is a three-phase asynchronous motor, and its model is YE3-90L-4. The rotating motor 11 is a forward and reverse motor, which can drive the threaded rod 12 to rotate forward and reverse.

[0027] The output end of the rotating motor 11 is coaxially fixedly connected with a threaded rod 12. The upper end of the movable groove 6 is closed. The upper end surface of the threaded rod 12 is higher than the upper end surface of the movable groove 6 to prevent the L-shaped block 7 from escaping from the L-shaped groove when moving upward.

[0028] The shaft of the threaded rod 12 is threadedly connected with a threaded sleeve 13, which is rectangular in shape and is fitted and slidably connected to the fixed column 2 to ensure that the rotation of the threaded rod 12 can drive the threaded sleeve 13 to slide vertically on the shaft of the threaded rod 12.

[0029] A connecting block 14 is fixedly connected between the threaded sleeve block 13 and the L-shaped block 7. A movable groove 6 connected to the L-shaped groove 5 is provided on the fixed column 2 located at the left front corner, and the width of the movable groove 6 is smaller than the width of the L-shaped groove 5. The connecting block 14 is arranged to pass through the movable groove 6 to prevent the L-shaped block 7 from detaching from the L-shaped groove 5.

[0030] The working principle of the utility model is as follows:

[0031] When loading and unloading goods, the rotating motor 11 drives the threaded rod 12 to rotate, driving the threaded sleeve block 13 to slide upward, and driving the L-shaped block 7 and multiple mobile protection rods 9 to move upward through the connecting block 14 until the connecting block 14 abuts against the inner top wall of the movable groove 6, and the distance between the mobile protection assembly and the low-bed semi-trailer body 1 reaches the maximum. At this time, loading and unloading are carried out from the gap between the front end and the left end of the low-bed semi-trailer body 1; when transporting goods, the rotating motor 11 drives the threaded rod 12 to rotate in the opposite direction, moving the mobile protection assembly downward, and cooperating with the fixed protection rod 3 to protect the goods on all sides.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein by equivalents. These modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
