Description

Technical Field

[0001] This utility model relates to the field of low-bed semi-trailer technology, and in particular to a low-bed semi-trailer with an anti-slip structure. Background Technology

[0002] As a core component of heavy-duty special transport vehicles, the low-flatbed semi-trailer is designed to meet the needs of transporting large cargo. It adopts an ultra-low flatbed structure to reduce loading height, and the frame is welded from high-strength alloy steel to ensure load-bearing strength. The flatbed surface is specially treated to form a flat cargo contact surface. The gooseneck design optimizes the overall vehicle's center of gravity distribution, and the suspension system adopts a multi-axle balanced structure to adapt to complex road conditions. This type of vehicle is widely used for long-distance transportation of non-detachable cargo such as construction machinery and large equipment. Its open platform design facilitates the loading and securing of various cargoes, but it also brings technical challenges to the anti-slip and securing of cargo.

[0003] Traditional low-flatbed semi-trailers commonly face the risk of cargo slippage during transportation. While the smoothness of the flatbed surface facilitates loading and unloading, it also reduces the coefficient of friction. The inertial force during vehicle start-up and braking can easily cause unsecured cargo to shift, and the centrifugal force during turns exacerbates the tendency for cargo to slide laterally. Rain and snow can cause a water film to form on the metal flatbed surface, further reducing friction. Transportation vibrations can cause the accumulation of small displacements between the cargo and the platform, eventually leading to positional shifts. Existing securing devices such as ropes and straps are cumbersome to operate and have issues with concentrated pressure. Some fragile cargo cannot withstand the localized pressure of traditional securing methods. These factors make anti-slip safety during cargo transportation a pain point in the industry.

[0004] Conventional solutions involve machining anti-slip textures on the flat surface to increase friction resistance. Mechanically stamped textures can increase surface roughness, but this static anti-slip measure has significant limitations. The texture height is limited to avoid affecting the smoothness of loading and unloading goods. After long-term use, the texture wears down, causing the anti-slip performance to continuously decline. In low-temperature winter environments, ice forms on the flat surface, causing the texture to be covered by ice and become ineffective. The temperature difference between day and night causes repeated freeze-thaw cycles, accelerating the damage to the texture structure. A single texture design cannot meet the anti-slip needs of goods made of different materials, and the lack of an active adjustment mechanism makes it difficult to cope with dynamically changing transportation conditions. These problems have prompted the industry to seek more intelligent and reliable anti-slip technology solutions. Summary of the Invention

[0005] The purpose of this utility model is to provide a low-bed semi-trailer with an anti-slip structure, which solves the problem of poor anti-slip effect of traditional low-bed semi-trailers.

[0006] To achieve the above objectives, this utility model provides a low-bed semi-trailer with an anti-slip structure, comprising a semi-trailer body, a flatbed fixedly mounted on the upper end of the semi-trailer body, an anti-slip mechanism fixedly mounted on the upper end of the flatbed, the flatbed comprising a steel plate, heating wires interlaced inside the steel plate, a heat-conducting sleeve surrounding the heating wires, a heating device fixedly mounted on the left end of the flatbed, the heating device being connected to the heating wires, a heat insulation layer fixedly mounted on the lower end of the steel plate, and a temperature sensor fixedly mounted inside the steel plate. The semi-trailer body serves as the load-bearing foundation frame for the entire device, providing an installation platform for all functional components. The flatbed, fixed to the upper part of the body, forms the cargo-bearing surface. The steel plate constitutes the core load-bearing layer of the flatbed and transmits the load. The heating wires form a heating network inside the steel plate to achieve uniform heat conduction. The heat-conducting sleeve wraps around the heating wires to improve heat utilization. The heating device provides a controllable power input to the heating wires. The heat insulation layer prevents heat from the steel plate from being transferred downwards. The temperature sensor monitors the temperature of the steel plate in real time and provides feedback to the control system.

[0007] The anti-slip mechanism includes a first slot, the upper end of the plate has a first slot, and the inside of the plate has a movable groove. The first slot provides a lifting channel for the movable block, and the movable groove accommodates the moving components of the anti-slip mechanism. The movable block generates vertical displacement under the pressure of the cargo.

[0008] The first slot has a movable block inside, and a limit end is fixedly provided at the lower end of the movable block. The movable block generates vertical displacement under the pressure of the cargo, and the limit end restricts the movement of the movable block to prevent it from falling out.

[0009] The movable block has a rubber protrusion fixedly installed at its upper end. The upper end of the rubber protrusion has several second slots. The rubber protrusion directly contacts the goods and generates elastic deformation. The second slots provide a bolt installation channel and release the rubber deformation space.

[0010] The lower end of the rubber protrusion is fixedly provided with a locking block, and the lower end is provided with a locking groove. The locking block engages with the locking groove. A bolt is fixedly provided inside the second groove. The locking block and the locking groove form a quick-release connection structure. The bolt fixing assembly adjusts the damping preload at the same time.

[0011] The movable block is equipped with a damper inside. The bolt passes through the rubber protrusion and the damper and is fixed to the lower surface of the movable groove. The damper absorbs the vibration energy of the cargo to achieve buffering. The steel plate bears the main structural strength of the whole system.

[0012] The upper surface of the steel plate is fixedly provided with anti-slip patterns, and the surface of the anti-slip patterns is sprayed with an anti-slip coating. The anti-slip patterns and the coating form a passive anti-slip layer, and the movable block assembly and the damper form an active anti-slip unit.

[0013] This device achieves dynamic and static dual protection through a composite anti-slip structure. The anti-slip texture and anti-slip coating on the flat surface form the basic anti-slip layer. The arrayed rubber bumps deform under the pressure of the cargo and activate the damper buffer mechanism. Multiple anti-slip units can independently adjust the preload to adapt to cargo of different weights. The heating system and temperature sensor work together to automatically melt ice and snow. The heat-conducting sleeve ensures heating uniformity while the heat insulation layer prevents energy loss. The snap-fit ​​structure allows for quick replacement of rubber parts. The anti-slip mechanism adopts a layered assembly structure. The rubber bumps can be disassembled and assembled without tools through the cooperation of the snap-fit ​​blocks and slots. The bolts serve the dual functions of connection and damping adjustment. The cooperation between the movable block and the limit end prevents the components from falling off. The combination of the heating wire and the heat-conducting sleeve facilitates local maintenance and replacement. The anti-slip coating can be repeatedly sprayed for maintenance. The layout of each functional unit without interference greatly reduces maintenance costs. Users can selectively replace parts according to wear conditions rather than disassembling and repairing the entire unit. Attached Figure Description

The semi-trailer body 1 serves as an overall support frame bearing the weight of all components, the flatbed 2 is fixed to the upper part of the body to form a cargo carrying platform, and the steel plate 4 constitutes the core load-bearing structure of the flatbed 2. The heating element 8 forms a heating circuit inside the steel plate 4 to achieve uniform heating. The heat-conducting sleeve 7 wraps around the heating element 8 to improve heat conduction efficiency. The heating device 9 provides a controllable power supply to the heating element 8 and adjusts the output power. The heat insulation layer 10 prevents heat from the steel plate 4 from being transferred downwards, reducing energy consumption. The temperature sensor 11 monitors the temperature of the steel plate 4 in real time and provides feedback to the control system. The anti-slip texture 5 forms a physical anti-slip structure on the surface of the steel plate 4. The anti-slip coating 6 enhances the surface friction coefficient of the anti-slip texture 5. The heating element 8 achieves precise regional heating. The heat-conducting sleeve 7 optimizes the uniformity of heat distribution. The heating device 9 realizes the conversion control of electrical energy and thermal energy. The heat insulation layer 10 establishes thermal management zones. The temperature sensor 11 constitutes a temperature control feedback node.

[0024] Please see Figures 1-6 The anti-slip mechanism 3 includes a first groove 301. The upper end of the plate 2 has the first groove 301. The inside of the plate 2 has a movable groove 310. The inside of the first groove 301 is movably arranged a movable block 302. The lower end of the movable block 302 is fixedly provided with a limit end 303. The upper end of the movable block 302 is fixedly provided with a rubber protrusion 304. The upper end of the rubber protrusion 304 has several second grooves 305. The first groove 301 provides a vertical movement channel for the movable block 302. The movable groove 310 accommodates the moving components of the anti-slip mechanism 3. The movable block 302 moves up and down along the first groove 301 under the pressure of the cargo. The limit end 303 limits the maximum stroke of the movable block 302 to prevent it from falling off. The rubber protrusion 304 directly contacts the cargo to generate elastic deformation to buffer vibration. The second grooves 305 provide installation space for the bolt 308 and release the rubber deformation allowance.

[0025] Please see Figures 3-5A locking block 306 is fixedly installed at the lower end of the rubber protrusion 304, and a locking groove 307 is opened at the lower end of the rubber protrusion 304. The locking block 306 and the locking groove 307 are engaged. A bolt 308 is fixedly installed inside the second groove 305. A damper 309 is fixedly installed inside the movable block 302. The bolt 308 passes through the rubber protrusion 304 and the damper 309 and is fixed to the lower surface of the movable groove 310. Anti-slip texture 5 is fixedly installed on the upper surface of the steel plate 4. The surface of the anti-slip texture 5 is sprayed with an anti-slip coating 6. The locking block 306 and the locking groove 307 form a quick disassembly and assembly structure for easy replacement. The bolt 308 fixes the assembly and adjusts the preload of the damper 309. The damper 309 absorbs the vibration energy of the goods to achieve dynamic buffering.

[0026] Working principle: The semi-trailer body 1 is a supporting structure. The flat plate 2 on its upper part forms the basic bearing surface through the steel plate 4. The electric heating wires 8 inserted inside the steel plate 4, together with the outer heat-conducting sleeve 7, achieve uniform heat conduction. When water freezes at a low temperature, the heating device 9 is activated and heats the steel plate 4 through the electric heating wires 8. The heat insulation layer 10 prevents heat from dissipating downwards. The anti-slip texture 5 and the anti-slip coating 6 on the surface of the steel plate 4 form a primary anti-slip layer. In the anti-slip mechanism 3, the movable blocks 302 in the first slot 301 arranged in an array are constrained in their displacement range by the limiting end 303. When the rubber protrusion 304 is pressed, it drives the movable block 302 to press down the damper 309 to generate a buffer. The cooperation between the locking block 306 and the locking groove 307 realizes the locking of the rubber protrusion 302. 4. Quick assembly and disassembly: Bolt 308 passes through the second slot 305 to adjust the preload of damper 309 to adapt to different cargo weights. When multiple anti-slip mechanisms 3 work together, vibration energy is absorbed step by step by damper 309. The surface texture of rubber bump 304 and anti-slip texture 5 of steel plate 4 form a composite anti-slip system. In winter, heating device 9 melts the ice layer on the surface of steel plate 4 through heating wire 8. Heat-conducting sleeve 7 ensures heating uniformity. Temperature sensor 11 regulates heating temperature in real time. Anti-slip coating 6 maintains adhesion performance under heating. Movable groove 310 provides movement space for movable block 302. Bolt 308 simultaneously undertakes the dual functions of connection and preload adjustment. Rubber bump 304 can be replaced individually after wear without affecting the overall structure.
