Description

Technical Field

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

[0002] In the field of logistics and transportation, low-bed semi-trailers have become an indispensable tool for transporting large and heavy goods due to their unique structural advantages. Low-bed semi-trailers have a lower loading platform, which can reduce the loading height of goods, thereby improving the stability and safety during transportation. They are especially suitable for transporting oversized and overweight goods such as engineering machinery and equipment, large steel structures, and transformers, and play a key role in many industries such as infrastructure construction, industrial production, and energy development. However, in actual transportation, traditional low-flatbed semi-trailers are clearly inadequate in preventing materials from slipping. Some vehicles rely solely on simple straps or ropes to secure the cargo, but this method often fails to provide sufficient restraint when faced with complex road conditions and strong inertial forces, making them prone to loosening or breaking. Some vehicles also install fixed-height baffles along the edges of the vehicle body in an attempt to prevent cargo from slipping. However, these baffles have limited height and strength, and cannot effectively protect oversized or overweight cargo. Furthermore, fixed baffles lack flexibility in use and cannot be adapted to the shape and size of different cargoes. Utility Model Content

[0003] (a) Technical problems to be solved To address the problems existing in the prior art, this utility model provides a low-flatbed semi-trailer with anti-fall function.

[0004] (II) Technical Solution To achieve the above objectives, this utility model is implemented through the following technical solution: a low-flatbed semi-trailer with anti-fall function, including a vehicle body, a baffle plate symmetrically and fixedly connected to the top of the vehicle body, a blocking rod slidably connected inside the baffle plate, a lifting assembly for raising and lowering the blocking rod inside the baffle plate, and a limiting assembly for preventing materials from falling off the top of the vehicle body. The limiting component includes symmetrical blocking grooves on the top of the vehicle body. A connecting plate is symmetrically fixedly connected inside the blocking groove. A rotating rod is fixedly connected inside the connecting plate. A blocking seat is rotatably connected to the outer wall of the rotating rod through a bearing. An extrusion block is fixedly connected to the outer wall of the blocking seat. A hiding component for hiding the blocking seat is provided inside the blocking groove.

[0005] As a preferred embodiment of the low-flatbed semi-trailer with anti-fall function described in this utility model, the hidden component includes an electric push rod fixedly connected to the inside of the blocking groove. A slider is fixedly connected to the output end of the electric push rod. A support rod is rotatably connected inside the slider through a bearing. Connecting bars are rotatably connected to both ends of the support rod through bearings. A connecting rod is fixedly connected inside the blocking seat. The end of the connecting bar away from the slider is rotatably connected to the outer wall of the connecting rod through a bearing.

[0006] As a preferred embodiment of the low-flatbed semi-trailer with anti-fall function described in this utility model, the lifting assembly includes lifting slots equidistantly opened on the top of the baffle, the outer wall of the blocking rod is slidably connected to the inner side of the lifting slot, and the outer wall of the baffle is provided with sliding slots equidistantly opened, the sliding slots penetrating into the interior of the lifting slot.

[0007] As a preferred embodiment of the low-flatbed semi-trailer with anti-fall function described in this utility model, a connecting column is fixedly connected to the side of the blocking bar near the sliding groove, two electric telescopic rods are symmetrically fixedly connected to the top of the vehicle body, a fixed plate is fixedly connected to the output end of the electric telescopic rod, and the end of the connecting column away from the blocking bar is fixedly connected to the outer wall of the fixed plate.

[0009] In a preferred embodiment of the low-flatbed semi-trailer with anti-fall function described in this utility model, the upper end of the blocking bar is inclined.

[0010] (III) Beneficial Effects This utility model provides a low-bed semi-trailer with anti-fall function. It has the following beneficial effects: 1. By setting a limiting component, the blocking seat can be flexibly hidden and unfolded. When the blocking seat is not needed, the electric push rod retracts, driving the slider to move, and then the blocking seat is stored in the blocking groove through the support rod and connecting strip, keeping the top of the vehicle flat and facilitating the loading and unloading of goods. When it is necessary to fix the goods, the electric push rod extends, pushes the slider to move, and rotates the blocking seat out of the blocking groove, quickly forming an effective anti-slip structure. The operation is simple and quick. In addition, the blocking seat can be rotated to adjust the angle and position, and can closely fit goods of various shapes, whether they are regular rectangular goods or irregular irregular shaped goods, they can be effectively fixed. 2. By setting up a lifting component, the barrier bar can be raised to a suitable position to effectively block the goods and prevent them from jumping or slipping during transportation due to vehicle bumps or sudden braking. When transporting shorter goods, the barrier bar can be lowered to avoid the barrier bar being too high and affecting the loading and securing of the goods, while also reducing unnecessary space occupation. This precise height adjustment capability allows the barrier bar to better adapt to the transportation needs of goods of different heights, greatly enhancing the effectiveness of the anti-fall function.

Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Example 1 Reference Figure 1 , Figure 2 , Figure 4 and Figure 5This is the first embodiment of the present invention. This embodiment provides a low-bed semi-trailer with anti-fall function, including a vehicle body 1. A baffle 2 is symmetrically fixedly connected to the top of the vehicle body 1. A blocking rod 3 is slidably connected inside the baffle 2. A lifting component 6 for raising and lowering the blocking rod 3 is provided inside the baffle 2. A limiting component 4 for preventing materials from falling is provided on the top of the vehicle body 1. The limiting component 4 includes a blocking groove 401 symmetrically opened on the top of the vehicle body 1. A connecting plate 402 is symmetrically fixedly connected inside the blocking groove 401. A rotating rod 403 is fixedly connected inside the connecting plate 402. A blocking seat 404 is rotatably connected to the outer wall of the rotating rod 403 through a bearing. A pressing block 405 is fixedly connected to the outer wall of the blocking seat 404. A hiding component 5 for hiding the blocking seat 404 is provided inside the blocking groove 401.

[0020] Specifically, the hidden component 5 includes an electric push rod 501 fixedly connected to the inside of the blocking groove 401. A slider 502 is fixedly connected to the output end of the electric push rod 501. A support rod 503 is rotatably connected inside the slider 502 via a bearing. Connecting bars 504 are rotatably connected to both ends of the support rod 503 via bearings. A connecting rod 505 is fixedly connected inside the blocking seat 404. The end of the connecting bar 504 away from the slider 502 is rotatably connected to the outer wall of the connecting rod 505 via a bearing.

[0021] Furthermore, when preparing to load goods, the operator first activates the electric push rod 501 to retract. Its output end drives the slider 502 to move closer to the electric push rod 501. During the movement of the slider 502, the linkage mechanism composed of the support rod 503 and the connecting bar 504 deforms, pulling the blocking seat 404 to rotate around the rotating rod 403, and retracting the blocking seat 404 into the blocking groove 401, keeping the top of the vehicle body 1 flat. Then, the goods to be transported are loaded onto the vehicle body 1 according to the predetermined position and method. After the goods are loaded, the electric push rod 501 is activated again. 01 extends, and its output end pushes the slider 502 to move away from the electric push rod 501. The movement of the slider 502 drives the support rod 503 and the connecting bar 504 to move, thereby pushing the blocking seat 404 to rotate around the rotating rod 403, so that the blocking seat 404 rotates out of the blocking groove 401. When the blocking seat 404 rotates to the appropriate position, the pressing block 405 on its outer wall is in close contact with the surface of the goods. Through the friction between the pressing block 405 and the goods, the goods are firmly fixed to the vehicle body 1, preventing the goods from sliding or falling due to bumps, turns or other situations during vehicle operation.

[0022] Example 2 Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The lifting component 6 includes lifting grooves 601 that are equidistantly opened on the top of the baffle 2. The outer wall of the blocking rod 3 is slidably connected to the inner side of the lifting groove 601. The outer wall of the baffle 2 is provided with sliding grooves 602 that are equidistantly opened and penetrate into the interior of the lifting groove 601.

[0023] Specifically, a connecting column 603 is fixedly connected to the side of the blocking rod 3 near the sliding groove 602. Two electric telescopic rods 604 are symmetrically fixedly connected to the top of the vehicle body 1. A fixing plate 605 is fixedly connected to the output end of the electric telescopic rod 604. The end of the connecting column 603 away from the blocking rod 3 is fixedly connected to the outer wall of the fixing plate 605. A guide rail is fixedly connected inside the blocking groove 401. The outer wall of the guide rail is slidably connected to the bottom of the slider 502. The upper end of the blocking rod 3 is inclined.

[0024] Furthermore, when preparing to load goods, the operator activates the electric telescopic rod 604 to retract the telescopic rod according to the expected height of the goods. The output end pulls the fixed plate 605 downward. The fixed plate 605, through the connecting column 603, drives the blocking rod 3 to descend within the lifting groove 601, placing the blocking rod 3 in a lower position to make enough space for loading the goods. After the goods are loaded, the electric telescopic rod 604 is activated again to extend the telescopic rod. The output end pushes the fixed plate 605 upward. The fixed plate 605, through the connecting column 603, drives the blocking rod 3 to rise within the lifting groove 601. When the blocking rod 3 rises to a suitable height, its upper end contacts the bottom or side of the goods, and the friction generated by the inclined surface helps to secure the goods.

[0025] Working principle: When preparing to load goods, the operator first activates the electric push rod 501 to retract. Its output end drives the slider 502 to move closer to the electric push rod 501. During the movement of the slider 502, the linkage mechanism composed of the support rod 503 and the connecting bar 504 deforms, pulling the blocking seat 404 to rotate around the rotating rod 403, and retracting the blocking seat 404 into the blocking groove 401, keeping the top of the vehicle body 1 flat. Then, the goods to be transported are loaded onto the vehicle body 1 according to the predetermined position and method. After the goods are loaded, the electric push rod 501 is activated again. 01 extends, and its output end pushes the slider 502 to move away from the electric push rod 501. The movement of the slider 502 drives the support rod 503 and the connecting bar 504 to move, thereby pushing the blocking seat 404 to rotate around the rotating rod 403, so that the blocking seat 404 rotates out of the blocking groove 401. When the blocking seat 404 rotates to the appropriate position, the pressing block 405 on its outer wall is in close contact with the surface of the goods. Through the friction between the pressing block 405 and the goods, the goods are firmly fixed to the vehicle body 1, preventing the goods from sliding or falling due to bumps, turns, etc. during the vehicle's operation. When preparing to load goods, the operator activates the electric telescopic rod 604 to retract the rod according to the expected height of the goods. The output end pulls the fixed plate 605 downward. The fixed plate 605, through the connecting column 603, causes the blocking rod 3 to descend within the lifting groove 601, placing the blocking rod 3 in a lower position to make enough space for loading the goods. After the goods are loaded, the electric telescopic rod 604 is activated again to extend the rod. The output end pushes the fixed plate 605 upward. The fixed plate 605, through the connecting column 603, causes the blocking rod 3 to rise within the lifting groove 601. When the blocking rod 3 rises to a suitable height, its upper end contacts the bottom or side of the goods, and the friction generated by the inclined surface helps to secure the goods.
