[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] First embodiment:

[0027] See Figs. 1-3 As shown, this utility model provides a FOD (Focus on Debris) sweeping mat traction and towing device, including a mounting base 1 and multiple inclined supports 2. Each inclined support 2 has a connecting frame 4 at its bottom end. The main function of the connecting frame 4 is to fix the sweeping mat, ensuring that the sweeping mat remains firmly connected to the device during towing and preventing it from falling off or shifting position. At the same time, auxiliary wheels 3 are also installed at the bottom of the inclined supports 2. The auxiliary wheels 3 can effectively reduce the frictional resistance between the device and the ground during movement, making the overall towing operation smoother and less strenuous.

[0028] To accommodate the use of sweeping mats of different sizes, an adjustable spacing component 5 is specially installed between two adjacent diagonal supports 2. This component can be operated to flexibly adjust the distance between adjacent diagonal supports 2, thereby ensuring that the sweeping mat can be fully unfolded according to the operational requirements, guaranteeing the sweeping coverage and effect. In addition, the horizontal rotating shaft 102 is connected to one of the diagonal supports 2. This connection method allows the rotation of the horizontal rotating shaft 102 to directly drive the corresponding diagonal support 2 to change its angle. Combined with the rotation adjustment of the vertical rotating shaft 101, the dragging direction of the entire device can be flexibly adjusted to meet the needs of different operating paths.

[0029] The second embodiment differs from the first embodiment in that:

[0030] In this FOD sweeping blanket traction device, the number of diagonal braces 2 is set to an odd number. This number design provides favorable conditions for the force balance and structural stability of the device. Since the odd number of diagonal braces 2 can form a distribution pattern with the middle as the center of symmetry, the force of each diagonal brace 2 can be more even when bearing the weight of the sweeping blanket and transmitting traction force, avoiding wear or damage to local parts due to force concentration, and further improving the overall durability of the device.

[0031] Specifically, the horizontal pivot 102 is fixedly connected to the diagonal brace 2 located in the middle. The diagonal brace 2, as the central support point of the entire diagonal brace frame, is fixedly connected to the horizontal pivot 102, which allows the rotational force of the horizontal pivot 102 to be transmitted more directly and evenly to the entire diagonal brace 2 system.

[0032] When the horizontal shaft 102 rotates, the central diagonal brace 2 will first change its angle, and then drive other diagonal braces 2 to adjust in coordination through the connection between adjacent diagonal braces 2. This ensures that all diagonal braces 2 can maintain a synchronous and stable motion state during the direction adjustment process, effectively avoiding the dragging effect of the sweeping blanket due to uneven force or inconsistent movement of each diagonal brace 2, and further enhancing the accuracy and reliability of the device operation.

[0033] In this FOD sweeping blanket traction device, the inclined support 2 is set at an angle, and the auxiliary wheel 3 includes a wheel body 301. A horizontal plate is rotatably connected to the outer side of the wheel axle of the wheel body 301. A mounting block is connected to the top of the horizontal plate through a support spring 302. The support spring 302 is set vertically, while the mounting block is fixedly connected to the inclined support 2. This structure gives the auxiliary wheel 3 good buffering and shock absorption performance. When the device moves on uneven ground, the bumps of the ground will be transmitted to the horizontal plate through the wheel body 301. At this time, the support spring 302 will absorb the vibration energy through its own elastic deformation, reducing the impact of vibration on the inclined support 2 and the entire device structure. This not only makes the device move more smoothly, but also reduces the risk of loosening or damage to components due to vibration, extending the service life of the device. At the same time, the rotatable connection between the wheel body 301 and the wheel axle ensures the flexible rotation of the auxiliary wheel 3. Combined with the inclined setting of the inclined support 2, this makes the device smoother and more flexible during turning and movement.

[0034] In the structure of the auxiliary wheel 3, the number of support springs 302 is set to multiple, and these support springs 302 are evenly distributed on the cross plate; this even distribution of multiple springs further optimizes the buffering and shock absorption effect of the auxiliary wheel 3.

[0035] Multiple support springs 302 can jointly bear the vibration and impact force from the ground. Compared with a single spring, the force can be distributed more evenly to various parts of the horizontal plate, avoiding premature fatigue damage of the springs due to excessive local force, and effectively improving the overall service life of the support springs 302.

[0036] Meanwhile, each of the multiple diagonal braces 2 is equipped with an auxiliary wheel 3 at its bottom. Each auxiliary wheel 3 contains multiple springs, and the evenly distributed layout allows the cross plate to maintain a more stable stress state when subjected to vibration, preventing tilting or swaying caused by uneven spring distribution. This makes the elastic deformation of the support springs 302 more coordinated and consistent, enabling more efficient absorption and buffering of vibration energy from different directions, further reducing the transmission of vibration to the diagonal braces 2 and the entire device structure, and ensuring that the device remains stable when moving in complex ground environments. In addition, the synergistic effect of multiple support springs 302 also enhances the adaptability of the auxiliary wheels 3 to different ground undulations. Whether the ground has a small bump or a depression, the evenly distributed springs can respond in time, providing stable support for the wheel body 301 and ensuring the continuity and reliability of the sweeping blanket traction process.

[0037] The third embodiment differs from the first embodiment in that:

[0038] The connecting frame 4 has an opening on the side away from the diagonal brace 2. The top surface of the connecting frame 4 is threaded with a clamping bolt for clamping the cleaning mat. When installing the cleaning mat, the operator can directly insert the edge of the cleaning mat into the connecting frame 4 through the opening. After the cleaning mat is inserted into the connecting frame 4, by tightening the clamping bolt, the bottom end of the bolt can be pressed tightly against the surface of the cleaning mat. The friction between the bolt and the cleaning mat is used to firmly fix the cleaning mat in the connecting frame 4.

[0039] This threaded connection is adjustable, allowing operators to flexibly adjust the bolt tightening force according to the thickness of the sweeping mat. This ensures that the sweeping mat will not loosen or fall off during dragging, and also prevents damage to the sweeping mat due to excessive pressure. In addition, the threaded connection is highly stable, and even in long-term, high-frequency operations, the tightening bolts can maintain a reliable tightening effect, ensuring the continuity and stability of the sweeping operation.

[0040] The fourth embodiment differs from the first embodiment in that:

[0041] The pitch adjustment assembly 5 includes an adjustment rod 502. The opposite end faces of the two diagonal braces 2 are rotatably connected to two rotating arms 501, and the movable ends of the corresponding rotating arms 501 on the two diagonal braces 2 are rotatably connected to the outside of the same moving seat 503, providing a stable transmission basis for pitch adjustment.

[0042] The adjusting rod 502 is a key component for adjusting the distance. It has external thread sections with opposite directions of rotation at both ends. The two external threads are threaded to the two moving seats 503 respectively. When it is necessary to adjust the distance between adjacent diagonal supports 2, the operator only needs to rotate the adjusting rod 502. Since the threads at both ends rotate in opposite directions, the two moving seats 503 will move in a straight line towards or away from each other along the adjusting rod 502 under the action of thread transmission. When the moving seats 503 move towards each other, they will push the two diagonal supports 2 closer to each other through the rotating arm 501, reducing the distance. When the moving seats 503 move away from each other, the rotating arm 501 will pull the two diagonal supports 2 away from each other, increasing the distance.

[0043] In addition, threaded connections have strong self-locking properties, and can stably maintain the current spacing after adjustment, avoiding unexpected changes in spacing due to vibration or other factors during operation.

[0044] In the structural design of the spacing adjustment component 5, the tilt direction of the adjusting rod 502 is consistent with the tilt direction of the inclined brace 2. Since the inclined brace 2 itself is tilted to adapt to the force requirements of the sweeping operation, the adjusting rod 502 maintains the same tilt direction as it. This allows the adjusting rod 502 to be more closely aligned with the force direction of the inclined brace 2 when transmitting the adjustment force, reducing the force decomposition loss and allowing the force generated during the adjustment process to act more directly on the spacing change of the inclined brace 2, thereby improving the adjustment efficiency.

[0045] This can prevent additional shearing force or torque from being generated at the connection between the rotating arm 501 and the diagonal brace 2 due to angular deviation, reduce the risk of wear at the component connection, and extend the service life of the adjustable pitch assembly 5.

[0046] In the structure of the adjusting assembly 5, both ends of the adjusting rod 502 are provided with limit blocks, and these limit blocks are located outside the moving seat 503, providing a reliable safety guarantee for the adjusting operation. The main function of the limit blocks is to limit the range of movement of the moving seat 503 on the adjusting rod 502, to prevent the moving seat 503 from disengaging from the threaded section of the adjusting rod 502 due to excessive movement, and to ensure the structural integrity of the adjusting assembly 5.

[0047] When the operator rotates the adjusting rod 502 to make the two moving seats 503 move towards or away from each other, the limit block will contact the moving seat 503 when it reaches the maximum movement limit position, preventing the moving seat 503 from continuing to move. The limit block can prevent it from falling off from both ends of the adjusting rod 502.

[0048] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
