Description

Technical Field

[0001] This utility model relates to the field of flatbed semi-trailer technology, and in particular to a low flatbed semi-trailer with a fall prevention mechanism. Background Technology

[0002] Flatbed semi-trailers are a common mode of transport, mainly used for transporting large and heavy goods. The bottom of a flatbed semi-trailer is a flat loading platform without side walls or a roof, making loading and unloading more convenient. Suitable for transporting items of various shapes and sizes, flatbed semi-trailers are typically made of high-strength materials and can carry heavy loads. They are widely used in industries such as construction, machinery, and engineering. Relying on a tractor unit for towing, flatbed semi-trailers offer high flexibility and adaptability, enabling them to operate under various road conditions.

[0003] However, existing methods for securing cargo to flatbed semi-trailers typically involve using ropes to secure the cargo. This method is not safe enough during transport, as the elasticity of the ropes can compromise the stability and safety. Furthermore, securing the cargo is cumbersome, time-consuming, and labor-intensive. Therefore, these issues need to be addressed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a low-flatbed semi-trailer with a fall prevention mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A low-bed semi-trailer with a fall protection mechanism includes a semi-trailer body. Fixed boxes are fixedly connected to both sides of the top of the semi-trailer body. Multiple support columns are rotatably connected inside each of the two fixed boxes. A rotating mechanism for rotating the multiple support columns is provided on both sides of the interior of the semi-trailer body. A connection port is provided at one end of the top of the semi-trailer body. A stop block is rotatably connected inside the connection port. Fixed shafts are fixedly connected to both symmetrical sides of the surface of the stop block. Two fixed shafts are rotatably fitted onto opposite sides inside the connection port. Through the sliding arrangement of two sliding rods and the support of multiple connecting rods, the multiple support columns can be rotated, thereby protecting both sides of the semi-trailer body and simultaneously rotating the stop block, thus improving the convenience of the device.

[0007] Preferably, the rotating mechanism includes a sliding rod. Two connecting slots are provided on the top of the semi-trailer body. Two fixing boxes are respectively fixedly connected to the top of the two connecting slots. The sliding rod is horizontally slidably connected inside one of the connecting slots. A bottom compartment is provided on one side of the bottom of the semi-trailer body. Multiple fixing rings are fixedly connected to one end of the bottom compartment. A hydraulic telescopic rod is installed inside the bottom compartment. The hydraulic telescopic rod is horizontally positioned and installed inside the multiple fixing rings. A slider is horizontally slidably connected inside the bottom compartment. The slider is located at the bottom of the connecting slot and is fixedly connected to one end of the sliding rod. The output end of the hydraulic telescopic rod is fixedly connected to the surface of the slider. Connecting rods are hinged inside multiple support columns. The bottom ends of multiple connecting rods are hinged to the top of the sliding rod. A crossbar is provided on the top of each pair of adjacent support columns. The two ends of the crossbars are respectively hinged to the top of each pair of support columns to restrict the sliding of the two sliders and the sliding rod. Supported by multiple connecting rods, multiple support columns will rotate, thereby improving the protective effect of the device.

[0008] Furthermore, a horizontal groove is formed at one end of the interior of the semi-trailer body. The two ends of the groove are respectively connected to the interior of two connecting grooves. The groove is connected to the interior of the connecting port. A limit rod is horizontally slidably connected inside the groove. The limit rod is horizontally set and its two ends are respectively fixedly connected to the two opposite sides of the sliding rod. An inclined groove is formed through the interior of the stop block. The limit rod is slidably connected inside the inclined groove. This allows the stop block to rotate under the connection of the limit rod while the two sliding rods are sliding.

[0009] The beneficial effects of this utility model are as follows:

[0010] 1. When in use, two hydraulic telescopic rods can be driven to extend and retract simultaneously, which will cause two sliders to slide. At the same time, the two sliding rods will also slide. Under the connection of multiple connecting rods, multiple support columns will be driven to rotate. When needed, multiple support columns can be rotated to a vertical position to protect both sides of the semi-trailer body.

[0011] 2. By sliding the two sliding rods to rotate multiple support columns, the limit rod will slide inside the inclined groove under the connection of the limit rod, which will simultaneously drive the stop block to rotate. The stop block will also protect one end of the semi-trailer body during use. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figures 1-5 A low-bed semi-trailer with a fall protection mechanism includes a semi-trailer body 1. Fixed boxes 2 are fixedly connected to both sides of the top of the semi-trailer body 1. Multiple support columns 3 are rotatably connected inside each of the two fixed boxes 2. Rotation mechanisms for rotating the multiple support columns 3 are provided on both sides of the interior of the semi-trailer body 1. A connection port 14 is provided at one end of the top of the semi-trailer body 1. A stop block 4 is rotatably connected inside the connection port 14. Fixed shafts 41 are fixedly connected to both symmetrical sides of the surface of the stop block 4. The two fixed shafts 41 are rotatably sleeved on opposite sides inside the connection port 14. Through the sliding arrangement of two sliding rods 5 and the support of multiple connecting rods 31, the multiple support columns 3 can be rotated, thereby protecting both sides of the semi-trailer body 1. Simultaneously, the stop blocks 4 are also rotated, thus improving the convenience of the device.

[0020] In this utility model, the rotating mechanism includes a slide rod 5. Two connecting slots 11 are provided on the top of the semi-trailer body 1. Two fixing boxes 2 are respectively fixedly connected to the top of the two connecting slots 11. The slide rod 5 is horizontally slidably connected inside one of the connecting slots 11. A bottom compartment 12 is provided on one side of the bottom of the semi-trailer body 1. Multiple fixing rings 13 are fixedly connected to one end of the bottom compartment 12. A hydraulic telescopic rod 52 is installed inside the bottom compartment 12. The hydraulic telescopic rod 52 is horizontally arranged and installed inside the multiple fixing rings 13. A slider 51 is horizontally slidably connected inside the bottom compartment 12. The slider 51 is located at the bottom of the connecting groove 11 and is fixedly connected to one end of the bottom of the slide rod 5. The output end of the hydraulic telescopic rod 52 is fixedly connected to the surface of the slider 51. Each of the multiple support columns 3 has a connecting rod 31 hinged inside. The bottom ends of the multiple connecting rods 31 are hinged to the top of the slide rod 5. Each of the two adjacent support columns 3 has a crossbar 32 at its top. The two ends of the multiple crossbars 32 are respectively hinged to the top of each pair of support columns 3 to restrict the sliding of the two sliders 51 and the slide rod 5. Under the support of the multiple connecting rods 31, the multiple support columns 3 will rotate, thereby improving the protective effect of the device.

[0021] In this utility model, a sliding groove 15 is horizontally opened at one end of the semi-trailer body 1. The two ends of the sliding groove 15 are respectively connected to the interior of two connecting grooves 11. The sliding groove 15 is connected to the interior of the connecting port 14.

The limiting rod 53 is slidably connected inside the inclined groove 42. When the two sliding rods 5 slide, the stop block 4 will rotate under the connection of the limiting rod 53.

[0022] Working Principle: In actual use, the sliding of two sliding rods 5 allows for the rotation of multiple support columns 3 via the support of multiple connecting rods 31, thus protecting both sides of the semi-trailer body 1. Simultaneously, it also drives the stop block 4 to rotate, improving the device's convenience. When in use, the two hydraulic telescopic rods 52 can be extended or retracted simultaneously, causing the two sliders 51 to slide. The two sliding rods 5 also slide, and with the connection of multiple connecting rods 31, the multiple support columns 3 rotate. When needed, the multiple support columns 3 can be rotated to a vertical position to protect both sides of the semi-trailer body 1. When not in use, the two support columns 3 can be rotated into the two fixed boxes 2, improving the device's effectiveness. Simultaneously, by sliding the two sliding rods 5 to rotate the multiple support columns 3, the limit rod 53 slides inside the inclined groove 42, simultaneously driving the stop block 4 to rotate. The stop block 4 also provides protection to one end of the semi-trailer body 1 during use.
