Description

Technical Field

[0001] This utility model relates to the field of road mat technology, and in particular to a heavy-duty overlapping road mat. Background Technology

[0002] In many fields such as construction engineering, oilfield mining, and temporary road paving, the frequent use of heavy machinery and vehicles has led to increasingly higher requirements for road load-bearing capacity and durability. Traditional road materials are prone to damage when faced with heavy loads, which not only affects the progress of the project but also increases maintenance costs and safety hazards. Therefore, developing a roadbed that can adapt to complex working conditions and has high load-bearing capacity has become a problem that the industry needs to solve.

[0003] Currently, most existing road mats are made of ordinary steel plates or wood panels. Steel plate road mats rely on their own metal strength to bear the load, while wood panel road mats provide a certain amount of support through the fiber structure of wood. The design of these traditional road mats is mainly based on the simple principle of splicing the panels. They form a temporary road surface through mechanical connection or direct laying. The technical principle is to use the physical strength of the panels themselves to disperse and transmit the pressure of vehicles and equipment in order to meet basic traffic needs.

[0004] However, existing technologies have obvious drawbacks. Due to long-term exposure to heavy vehicles and machinery, the surface of traditional road mats is severely worn, resulting in a significant reduction in their service life. Frequent replacement of road mats not only increases project costs but also seriously affects construction efficiency. Furthermore, the worn surface of the road mats becomes uneven, posing a significant safety hazard and failing to meet the long-term requirements for road stability and safety in engineering construction. Therefore, a heavy-duty overlapping road mat is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a heavy-duty overlapping road mat, which aims to improve the problems of severe surface wear, short service life, increased project costs, reduced construction efficiency, and safety hazards caused by heavy vehicles and mechanical equipment rolling over traditional road mats.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A heavy-duty overlapping road mat includes a bottom plate and a road mat body that are symmetrically arranged on both sides, and the bottom plate and the road mat body are provided with reinforcing components inside.

[0008] The reinforcing component includes anti-slip protrusions, which are fixedly connected to the surface of the road mat body. The surface of the road mat body is provided with an anti-corrosion layer, and the surface of the anti-corrosion layer is provided with a wear-resistant layer. Multiple reinforcing ribs are fixedly connected inside the bottom plate, and multiple connecting grooves are opened inside the bottom plate. Multiple locking shafts are slidably connected inside the road mat body, and the multiple locking shafts and the multiple connecting grooves are all fitted together. Splicing components are provided on one side of the bottom plate, which is symmetrical on both sides.

[0009] As a further description of the above technical solution:

[0010] The splicing assembly includes a first connecting block and a second connecting block. The first connecting block is fixedly connected to one of the side walls of the bottom plate, and the second connecting block is fixedly connected to the other side wall of the bottom plate.

[0011] As a further description of the above technical solution:

[0012] The first connecting block has a locking post 1 slidably connected inside, and the second connecting block has a locking post 2 slidably connected inside.

[0013] As a further description of the above technical solution:

[0014] The connecting block 2 is fixedly connected to the fitting block 1, and the fitting block 1 has a locking groove 1 inside.

[0015] As a further description of the above technical solution:

[0016] The connecting block 1 is fixedly connected to the fitting block 2, and the fitting block 2 has a locking groove 2 inside.

[0017] As a further description of the above technical solution:

[0018] The second locking pin engages with the second locking groove, and the first locking pin engages with the first locking groove.

[0019] As a further description of the above technical solution:

[0020] Both the first connecting block and the second connecting block have limiting grooves inside, and both the first fitting block and the second fitting block engage with the limiting grooves.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the anti-slip properties of the road mat body can be increased by the anti-slip protrusions, the overall strength of the bottom plate can be increased by the reinforcing ribs, and the wear-resistant and anti-corrosion properties of the road mat body can be further increased by the anti-corrosion layer and the wear-resistant layer, thereby achieving the effect of enhancing the overall strength of the bottom plate and the road mat body. This solves the problem of traditional road mats being easily damaged due to wear and corrosion, improves the efficiency of equipment passage and material transportation in engineering construction, and reduces the risk of construction delays caused by frequent replacement of road mats.

[0023] 2. In this utility model, by attaching two bottom plates together, the first and second fitting blocks are inserted into the limiting groove, and the second connecting block is engaged with the first connecting block. Then, by inserting the second locking post and the first locking post into the first locking groove and the second locking groove, the effect of quickly splicing multiple bottom plates is achieved, which solves the problems of time-consuming and complicated operation of traditional board splicing and improves the construction efficiency of temporary road paving and site transfer.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3 The present invention provides an embodiment of a heavy-duty overlapping road mat, comprising a bottom plate 1 and a road mat body 2 symmetrically arranged on the left and right sides. Both the bottom plate 1 and the road mat body 2 are provided with reinforcing components. The reinforcing components are used to enhance the overall strength and function of the bottom plate 1 and the road mat body 2.

[0034] The reinforcing components include anti-slip protrusions 4, which are fixedly connected to the surface of the road mat body 2. The function of the anti-slip protrusions 4 is to increase the friction of the road mat body 2, thereby preventing vehicles and pedestrians from slipping. An anti-corrosion layer 7 is provided on the surface of the road mat body 2. The function of the anti-corrosion layer 7 is to isolate the road mat body 2 from external corrosive substances, preventing its internal structure from being corroded and damaged, thus ensuring reliable operation throughout its service life and providing stable support for heavy equipment and vehicles. A wear-resistant layer 8 is provided on the surface of the anti-corrosion layer 7. It can greatly improve the surface hardness and wear resistance of the road mat plate body 2, reduce the labor cost, time cost and interference to normal construction or operation caused by replacing and repairing the road mat plate. The bottom plate 1 has multiple reinforcing ribs 5 fixedly connected inside, and multiple connecting grooves 3 are opened inside the bottom plate 1. Multiple locking shafts 6 are slidably connected inside the road mat plate body 2. The multiple locking shafts 6 and multiple connecting grooves 3 are all fitted together. Splicing components are provided on one side of the left and right symmetrical bottom plates 1. The splicing components are used to facilitate users to quickly splice multiple bottom plates 1.

[0035] Specifically, when road mats face problems such as increased wear due to frequent rolling by heavy equipment, corrosion risks from complex environments, slippery hazards caused by severe weather, and low efficiency of traditional splicing methods, which seriously affect their service life, safety, and construction efficiency, the operator first attaches the bottom plate 1 to the road mat body 2. Then, the locking shaft 6 is inserted into the connecting groove 3 on the road mat body 2, and by rotating the locking shaft 6, it is tightly engaged with the connecting groove 3, thereby achieving a quick overlap between the bottom plate 1 and the road mat body 2. The locking shaft 6 not only simplifies the assembly process but also ensures a stable connection and improves operational efficiency. The surface of the road mat body 2 is equipped with anti-slip protrusions 4, which provide protection for vehicles and pedestrians. While providing better friction, it also enhances the anti-slip performance of the road mat, thereby effectively reducing the risk of slipping and improving safety. In addition, the surface of the road mat body 2 is coated with an anti-corrosion layer 7, which forms a strong protective film to isolate the road mat body 2 from external corrosive substances, preventing its internal structure from being corroded and damaged due to long-term exposure to harsh environments, thus extending its service life. In order to cope with the wear and tear caused by long-term use, a wear-resistant layer 8 is also added to the surface of the road mat body 2. This wear-resistant protection reduces surface damage during long-term use, effectively delays wear, ensures that it can withstand more use cycles, and thus improves overall durability.

[0036] Reference Figures 4-6 The splicing assembly includes connecting block 1 (9) and connecting block 2 (10). Connecting block 1 (9) is fixedly connected to one side wall of one of the bottom plates 1, and connecting block 2 (10) is fixedly connected to one side wall of the other bottom plate 1. Connecting blocks 1 (9) and 2 (10) provide support and connection for the splicing assembly, ensuring quick assembly by operators. Connecting block 1 (9) has a sliding locking post 11, and connecting block 2 (10) has a sliding locking post 2 (12). Locking posts 11 and 12 provide locking for the splicing assembly, ensuring its stability after assembly. Connecting block 2 (10)... The internal fixed connection includes a first fitting block 13, which has a locking groove 14 inside. The internal fixed connection includes a second fitting block 15, which has a locking groove 16 inside. The second locking post 12 fits into the second locking groove 16. Through the cooperation of the second locking post 12 and the second locking groove 16, the locking and unlocking functions of the splicing components can be quickly realized, providing convenience for operators. The first locking post 11 fits into the first locking groove 14. The internal limit grooves 17 are opened in both the first connecting block 9 and the second connecting block 10. The first fitting block 13 and the second fitting block 15 are engaged with the limit grooves 17.

[0037] Specifically, in time-sensitive scenarios such as emergency rescue, temporary engineering construction, and rapid relocation of construction sites, as well as situations where it is frequently necessary to build or dismantle temporary roads and work platforms, operators first attach multiple bottom panels 1 together, and then use compression to fully engage connecting block 1 9 and connecting block 2 10, completing the initial splicing. Afterwards, operators insert locking pin 1 11 and locking pin 2 12 into locking slot 1 14 and locking slot 2 16 respectively. In this way, the stable splicing and positioning of multiple bottom panels 1 can be quickly achieved, making the splicing process of bottom panels 1 both simple and efficient, ensuring the stability of the overall structure, and avoiding loosening problems during the splicing process.

[0038] Working Principle: When using this heavy-duty overlapping road mat, the operator first attaches the bottom plate 1 and the road mat body 2 together. Then, the locking shaft 6 is inserted into the connecting groove 3 through the road mat body 2. By rotating the locking shaft 6, it engages with the connecting groove 3, achieving a quick overlap between the bottom plate 1 and the road mat body 2. The anti-slip protrusions 4 on the surface of the road mat body 2 increase its anti-slip performance, ensuring reliable friction for vehicles and pedestrians. The anti-corrosion layer 7 forms a strong protective film on the surface of the road mat body 2, isolating it from external corrosive substances and preventing corrosion. To prevent its internal structure from being corroded and damaged, the wear-resistant layer 8 can reduce surface damage caused by long-term wear, allowing the road mat body 2 to withstand more use cycles, thereby extending its overall service life. When temporarily splicing multiple panels, the operator will press the multiple bottom panels 1 together and then squeeze the multiple bottom panels 1 so that the connecting block 1 9 and the connecting block 2 10 are fully engaged, thereby achieving the initial splicing. Then, the operator will insert the locking pin 1 11 and the locking pin 2 12 into the locking groove 1 14 and the locking groove 2 16 to achieve quick locking and ensure that the multiple bottom panels 1 can be quickly spliced ​​and limited.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
