Description

Technical Field

[0001] The invention relates to the technical field of flatbed truck load-bearing technology, in particular to a grid-shaped anti-skid cargo platform structure for a flatbed truck. Background Art

[0002] Bulldozers, excavators, drills, and other large, heavy crawler equipment used in mining require roll-on / roll-off transport on special flatbed trucks to minimize track wear and improve efficiency. However, the heavy weight and sharp track teeth of mining crawler equipment create strong squeezing, shearing, and friction on the cargo platform. Existing anti-skid structures have the following drawbacks: For equipment that uses patterned steel plate anti-skid technology, the height of the raised patterned steel plate surface is limited, which cannot provide sufficient friction coefficient, and the anti-skid effect is insufficient, which can easily cause the equipment to slip.

[0003] When using wooden plank laying technology, the friction coefficient between wood and steel is high, but the track teeth are prone to causing damage such as knocking and crushing the wooden planks, requiring frequent replacement, poor durability and high maintenance costs.

[0004] The anti-slip strip technology of welded metal is heavy, which increases the load on the cargo platform and does not meet the lightweight requirements. It is only effective in longitudinal anti-slip, and the lateral anti-slip ability is insufficient. The welding process may easily cause the cargo platform to shrink and deform, affecting the structural stability.

[0005] The above existing technologies are unable to simultaneously meet the requirements of high strength, long life and multi-directional anti-slip, resulting in safety hazards in equipment transportation and high maintenance costs for cargo platforms.

[0006] Therefore, there is an urgent need to design a flatbed truck grid-shaped anti-skid cargo platform structure to enhance the stability of the cargo platform carrying crawler equipment and extend the service life of the cargo platform. Summary of the Invention

[0007] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a flatbed truck grid-shaped anti-skid cargo platform structure to enhance the stability of the cargo platform carrying crawler equipment and extend the service life of the cargo platform.

[0008] In order to achieve the above-mentioned purpose, a flatbed truck grid-shaped anti-slip cargo platform structure is designed, and the anti-slip cargo platform structure is a modular structure.

The grid-shaped supporting member is arranged in the frame to form a number of supporting inner grids, and the anti-slip member is arranged in each supporting inner grid; the anti-slip member is a deformable material, and the upper surface of the anti-slip member is higher than the upper surface of the grid-shaped supporting member, so that the anti-slip member wraps the track teeth of the crawler equipment carried by the cargo platform; the grid-shaped supporting member is a rigid material to form a rigid support limit for the track teeth, thereby limiting the degree to which the track teeth cut into the anti-slip member.

[0009] Preferably, the present invention further includes: the anti-slip cargo platform structure further includes a plurality of lower supporting bars, which are arranged at the bottom of the frame, and the lower supporting bars support the grid-shaped supporting components and anti-slip components in the frame.

[0010] Preferably, the present invention further comprises: a nut or a threaded hole is provided on the lower support bar, and a bolt passes through the anti-slip component and is threadedly engaged with the nut or the threaded hole, so that the anti-slip component is fixed in the supporting inner grid.

[0011] Preferably, the present invention further comprises: the anti-slip member is wood, rubber material or polymer material with deformation ability, Preferably, the present invention further comprises: the supporting member is made of metal material.

[0012] Preferably, the present invention further comprises: the upper surface of the grid-shaped supporting member is provided with a serrated, crenel-shaped or granular structure for engaging with the track teeth of the crawler equipment carried on the cargo platform.

[0014] Preferably, the present invention further comprises: the supporting inner grid of the grid-shaped supporting member comprises a square, circular, triangular, polygonal or other geometric shapes.

[0015] Compared with the prior art, the present invention has the following advantages: Anti-slip and durable, through the combination of rigid supporting components and elastic anti-slip components, the track teeth are rigidly limited after cutting in to avoid breakage; the elastic material wraps the track teeth to greatly increase friction and prevent slipping and overturning.

[0016] A lightweight process has been achieved, and the modular grille design reduces the use of steel and reduces weight; bolt fixation replaces welding to avoid deformation and simplify assembly.

[0017] The cargo platform has a uniform load and a long service life, the grid layout disperses the track pressure, and the contoured module matches the cavity structure to reduce local wear and extend the service life.

[0018] Effectively resisting lateral sliding, the serrations or crenellation surfaces of the supporting components engage with the track teeth to prevent lateral sliding or creeping and ensure driving stability.

DETAILED DESCRIPTION

[0021] In order to make the purpose, principle and structure of the present invention more clear, it is further described below with reference to the accompanying drawings and specific embodiments.

[0022] The invention provides a grid-shaped anti-skid cargo platform structure for a flatbed truck.

[0023] As attached Figures 1 to 14 As shown, this embodiment includes a plurality of modular anti-slip cargo platform structures 2, which are arranged on the cargo platform 1 of a flatbed truck. The anti-slip cargo platform structure 2 includes a frame 5 and a grid-shaped support member 3 arranged inside the frame 5. The grid-shaped support member 3 forms a plurality of inner compartments 6. The anti-slip member 4 is arranged in the inner compartments 6.

[0024] Preferably, the cargo platform 1 may be a frame structure, and the anti-slip cargo platform structure 2 is arranged inside the frame structure.

[0025] Preferably, the inner compartment 6 includes a first accommodating cavity 9 , a second accommodating cavity 10 , and a third accommodating cavity 11 .

[0026] Preferably, the frame 5 includes a plurality of longitudinal plates 15 arranged along the longitudinal direction and a plurality of transverse plates 16 arranged along the transverse direction. The longitudinal plates 15 and the transverse plates 16 together form the frame 5 structure, and the middle portion of the frame 5 is a hollow structure.

[0027] Preferably, the grid-shaped support member 3 is composed of a plurality of first grid bars 7 and a plurality of second grid bars 8 arranged at intervals. The first grid bars 7 and the second grid bars 8 are arranged obliquely and crosswise in the horizontal plane, forming an orthogonal or oblique grid-shaped mesh structure. Adjacent first grid bars 7 and second grid bars 8 together form a first accommodating cavity 9, the upper surface of which is a quadrilateral structure. The first grid bars 7, the second grid bars 8, and the longitudinal plate 15 together form a second accommodating cavity 10, the upper surface of which is a triangular structure. The first grid bars 7, the second grid bars 8, and the transverse plate 16 together form a third accommodating cavity 11, the upper surface of which is a triangular structure.

[0028] Preferably, adjacent first grille bars 7 are parallel to each other, and adjacent second grille bars 8 are parallel to each other. In this case, the upper surface of the first accommodating cavity 9 is a parallelogram structure, while the upper surfaces of the second and third accommodating cavities 10 and 11 are isosceles triangle structures. The intersection angle between the first grille bars 7 and the second grille bars 8 is set according to actual needs.

[0029] The anti-slip structure 4 includes a central module 12, side modules 13, and end modules 14. The central module 12 is disposed within the first accommodating cavity 9, while the side modules 13 and end modules 14 are disposed within the second accommodating cavity 10 and the third accommodating cavity 11, respectively. The central module 12, side modules 13, and end modules 14 are contoured to the first accommodating cavity 9, the second accommodating cavity 10, and the third accommodating cavity 11, respectively, ensuring a close fit between the modules and the cavities.

[0030] The bottom of the frame 5 is provided with a plurality of lower support bars 6-1, which are fixed to the bottom of the frame 5 by welding or riveting. The upper surface of the lower support bar 6-1 is provided with a nut 18 or a threaded hole. The bolt 17 passes through the middle module 12, the side module 13 and the end module 14 of the anti-slip member 4 and is threadedly engaged with the nut 18 or the threaded hole. The nut of the bolt 17 exerts a downward force on the anti-slip member 4, and the nut 18 or the lower support bar 6-1 exerts an upward force on the anti-slip member 4, together clamping the anti-slip member 4. The anti-slip member 4 is clamped both above and below and will not move. The lower side of the nut 18 is fixed to the lower support bar 6-1 or the threaded hole is fixedly set on the lower support bar 6-1. The reaction force generated by the rigid material properties of the fixed connection material ensures that the nut 18 or the threaded hole is fixed on the lower support bar 6-1, thereby fixing each module in the corresponding accommodating cavity.

[0031] Preferably, the middle module 12 , the side modules 13 and the end modules 14 of the anti-slip member 4 are all provided with through holes 19 , and the through holes 19 are used for the bolts 17 to pass through.

[0032] The anti-slip member 4 is made of a deformable material with a certain degree of elastic deformation. The upper surface of the anti-slip member 4 is higher than the upper surface of the lattice-shaped support member 3, forming a certain height difference D. When the tracked equipment on the cargo platform 1 runs on the anti-slip member 4, the grouser 20 exerts deformation pressure on the anti-slip member 4. Because the grouser 20 has a smaller force application area than the track, the pressure on the grouser 20 is higher, and the effect on the anti-slip member 4 is more significant. The anti-slip member 4 is deformed by the pressure from the track and the grouser 20, and this deformation causes the anti-slip member 4 to wrap around the grouser 20. The lattice-shaped support member 3 is made of a rigid material.

[0033] Preferably, the anti-slip member 4 is made of wood, rubber or elastic polymer material. The grid-shaped supporting member 3 is made of metal.

[0034] Preferably, the upper surface of the grating-shaped support member 3 is provided with a serrated, crenellated, or granular structure that meshes with the track teeth 20 to prevent lateral sliding. This also enhances the friction between the track teeth 20 and the grating-shaped support member 3, preventing the track teeth 20 from slipping and eliminating the phenomenon of the track teeth 20 slipping and damaging the anti-slip member 4 made of deformable material.

[0035] A guide portion 21 with a slope 23 is provided at the rear of the cargo platform 1. Anti-slip strips 24 are welded on the slope 23 and engage with the track teeth 20. The modular anti-slip cargo platform structure 2 and the guide portion 21 are connected by a hollow frame structure 22.

[0036] Specific working principle: The crawler equipment crawls up to the cargo platform 1 along the inclined surface 23 of the guide part 21, wherein the front part of the crawler equipment will be raised when it climbs over the inclined surface 23, and when it completely climbs over the inclined surface 23, its front part will fall down on the cargo platform 1 due to the shift of the center of gravity. By setting a hollow frame structure 22 between the anti-slip cargo platform structure 2 and the guide part 21 on the cargo platform 1, the equipment crawler teeth 20 are prevented from directly hitting the anti-slip component 3, but first hit the hollow frame structure 22 of the rigid material, and then the equipment gradually moves to the anti-slip cargo platform structure 2.

[0037] The crawler equipment running on the anti-skid cargo platform structure 2 generates pressure on the anti-skid cargo platform structure 2 under the action of gravity, and the track teeth 20, as the high-pressure part, will be pressed into the anti-skid member 4. After the track teeth 20 are pressed into the anti-skid member 4, the cutting depth is limited by the rigid support of the grid-shaped support member 3. When the elastic deformation of the anti-skid member 4 caused by the pressure of the track teeth 20 is greater than the height difference between the anti-skid member 4 and the upper surface of the grid-shaped support member 3, the track teeth 20 are in direct contact with the grid-shaped support member 3, and the grid-shaped support member 3 directly forms a rigid support for the track teeth 20. At this time, due to the rigid limit blockage, the track teeth 20 stop cutting into the anti-skid member 4, preventing the anti-skid member 4 from breaking through the material limit due to excessive shear force and excessive deformation.

[0038] At the same time, the elastic deformation of the anti-slip member 4 causes it to conformally wrap around the track teeth 20, providing a high coefficient of friction to prevent slippage and generating multi-directional static friction in the horizontal direction. The quadrilateral structure of the first accommodating cavity 9 and the triangular layout of the second and third accommodating cavities 10 and 11, combined with the contoured module design, ensure uniform load distribution and reduce local stress concentration. This structure ensures sufficient contact and friction between the module and the track teeth 20 while stabilizing the pressure-bearing structure. The structural coordination between the module and the cavity also prevents the module from being displaced from the cavity due to the action of forces.

[0039] This embodiment solves the problems of poor anti-slip effect, easy damage and process defects in the prior art through modular design, rigid support and elastic anti-slip material.

[0040] It is worth mentioning that: The scope of protection of the present invention is intended to cover: any technical solution for material selection that can meet the rigidity strength of the grid-shaped supporting member 3, as well as any technical solution for any crossing angle between the grid bars of the grid-shaped supporting member 3, any technical solution for the inner grid 6 in the grid-shaped supporting member 3 or the module in the anti-slip member 4 to be of any geometric shape, and any technical solution for the grid bars to adopt any cross-sectional structure and any material, all of which should fall within the scope of protection of the present invention.

[0041] Similarly, the scope of protection of the present invention is intended to cover: any material and shape expansion of the anti-slip component 4 that can be achieved by a person skilled in the art, any technical solution for manufacturing the anti-slip component 4 using materials with elasticity, toughness and high friction coefficient (such as rubber, polymers, composite materials, etc.), and technical solutions for the anti-slip component 4 to be designed with a contoured geometric structure (such as a quadrilateral, triangle or other polygonal shape) to adapt to different supporting inner grids 6.

[0043] Any technical solution that can achieve lightweight and modular implementation of the cargo platform by a person skilled in the art, any technical solution that directly integrates the anti-slip cargo platform structure 2 into the floor or frame of a flatbed truck, and any technical solution that adopts modular segmentation and sub-section arrangement of the anti-slip cargo platform structure 2.

[0045] All the above technical solutions, as long as they are based on the core design concept of the present invention, should fall within the scope of protection.

[0046] The above description is only a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent replacement or change made by any technician familiar with the technical field within the technical scope disclosed by the present invention based on the technical solution and novel concept of the present invention should be covered by the scope of protection of the present invention.
