Description

Technical Field

[0001] This utility model relates to the field of road construction technology, and in particular to an automatic paving device for colored anti-slip pavement. Background Technology

[0002] Colored anti-skid pavement is a high-friction, thin-layer pavement system formed by laying a polymer adhesive and spreading colored wear-resistant aggregate on the road surface, serving both safety warning and aesthetic purposes. MMA (methyl methacrylate) resin is typically used as the binder, and ceramic particles or quartz sand are used as aggregates. The aggregate particles increase the pavement texture depth, improve drainage in rainy weather, and increase tire contact point friction, thereby significantly improving the road surface friction coefficient.

[0003] However, in existing technologies, the construction method for colored anti-skid pavements typically involves cleaning the roadbed, laying MMA resin on the pavement, manually sprinkling aggregate particles onto the uncured MMA resin, and finally cleaning up and recycling the excess aggregate particles after the MMA resin has cured. This manual sprinkling method has several problems. First, manual operation is inefficient and cumbersome, making it difficult to ensure the uniformity of aggregate distribution. Second, manual sprinkling easily leads to the waste of aggregate particles, increasing construction costs. More importantly, because the aggregate is simply sprinkled onto the resin surface, some aggregate particles do not adhere firmly to the MMA resin, especially in the early stages of use, where they are prone to detachment. This not only affects the aesthetics of the pavement but, more importantly, reduces the coefficient of friction, potentially causing the pavement to become slippery and failing to fully realize the safety function of the colored anti-skid pavement.

[0004] To address the aforementioned issues, existing technologies urgently need improvement. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an automatic paving device for colored anti-slip pavement.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an automatic colored anti-slip pavement paving device, including a frame, and further comprising:

[0007] An air compressor, mounted on the frame, is used to output high-pressure air;

[0008] A connecting pipe, one end of which is connected to the air compressor;

[0009] The shunt pipe is connected to the other end of the connecting pipe and is used to shunt high-pressure air.

[0010] Multiple delivery pipes, each of which is connected at one end to the branch pipe;

[0011] Multiple spray guns, each of which is connected to the other end of a delivery pipe, and a nozzle is fixedly mounted on the end of the spray gun;

[0012] Multiple material tanks are fixedly installed on the frame. The material tanks are used to hold aggregate particles. Each material tank is equipped with a connecting cover, which is used to connect the material tank to the corresponding spray gun, so that the aggregate particles in the material tank are sucked in when high-pressure air passes through the spray gun.

[0013] When using the automatic colored anti-skid pavement paving equipment of this application, first move the equipment to the starting position of the road section already coated with MMA resin. Load aggregate particles into the hopper and securely connect the hopper to the corresponding spray gun using the connecting cap. Start the air compressor mounted on the frame. The air compressor starts working and outputs high-pressure gas. The high-pressure gas enters the distribution pipe along the connecting pipe and is distributed to various delivery pipes. The high-pressure gas flows through the delivery pipes to the spray guns connected to its ends. When the high-pressure gas flows at high speed through the inside of the spray gun, according to Bernoulli's principle, a local low pressure is generated in the area connected to the hopper. Under the action of this low pressure, the aggregate particles in the hopper are drawn into the high-speed gas flow, forming a mixture of gas and aggregate particles. This mixture is then sprayed through the nozzle of the spray gun onto the road surface below, i.e., the uncured MMA resin layer. Workers can push the equipment from both sides of the frame or connect external traction equipment, such as a cable reel, via hooks attached to the frame to move the equipment forward along the road track. During equipment movement, aggregate particles are continuously and uniformly sprayed onto MMA resin and embedded into the resin due to the kinetic energy of the spray. The frame provides overall support and a moving platform for the equipment, ensuring stable movement along the predetermined path. The air compressor is the power source for the entire system, providing the necessary air pressure. Connecting pipes, branch pipes, and delivery pipes form an efficient gas delivery and distribution network, ensuring that high-pressure gas is accurately delivered to each spray gun. The spray gun is a key component for achieving aggregate intake and mixing with gas; its design directly affects the aggregate delivery efficiency and spraying effect. The hopper provides storage space for the aggregate, and the connecting cover ensures that the aggregate is smoothly drawn into the spray gun. The nozzle controls the spray shape and range of the aggregate mixture, contributing to uniform aggregate coverage on the road surface. Through this automated paving process, aggregate particles are effectively embedded in the MMA resin, forming a strong bond, and the aggregate is randomly distributed, providing a high coefficient of friction for the colored anti-skid pavement and ensuring its anti-skid effect.

[0014] Furthermore, the frame includes a frame structure welded from metal tubing.

[0015] Furthermore, the frame is equipped with wheels at all four corners of its bottom.

[0016] Furthermore, the diversion pipe is arranged horizontally, and multiple delivery pipes are spaced apart along the length of the diversion pipe.

[0017] Furthermore, the spray gun includes a gun body and a connecting pipe for connecting the delivery pipe. One end of the gun body is connected to the connecting pipe, and the other end is connected to the nozzle. The material tank is connected to the gun body through the connecting cover.

[0018] Furthermore, the frame is equipped with hooks.

[0019] Furthermore, the container is made of transparent material.

[0020] Furthermore, the nozzle is flat.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] By configuring a frame, air compressor, connecting pipes, distribution pipes, delivery pipes, spray gun, aggregate tank, connecting cover, and nozzle, high-pressure air generated by the air compressor enters the spray gun through the connecting pipes, distribution pipes, and delivery pipes. At the spray gun, due to the structural design (e.g., the Venturi effect), the high-speed flowing high-pressure air generates low pressure, thereby drawing aggregate particles from the aggregate tank into the airflow, forming a mixture of aggregate particles and high-pressure air. This mixture is ultimately sprayed onto the uncured MMA resin pavement through the nozzle. This automated paving method significantly improves the efficiency of paving operations and reduces the hassle of manual operation compared to existing technologies that manually spread aggregate.

[0023] Meanwhile, by controlling the equipment's moving speed and spray volume, the aggregate spreading density can be more precisely controlled, effectively reducing aggregate waste. More importantly, the high-pressure air spraying method allows aggregate particles to embed into the uncured MMA resin with a certain speed and impact force, rather than simply falling onto the surface. This greatly improves the adhesion between the aggregate particles and the MMA resin, effectively solving the problem of aggregate easily falling off and causing road slippage in existing technologies, ensuring the long-term anti-slip effect and service life of colored anti-slip pavement.

[0028] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0029] This application relates to the technical field of automatic paving equipment for colored anti-skid pavement. Colored anti-skid pavement is widely used in road construction and maintenance due to its excellent anti-skid performance and aesthetic appeal. Traditional construction methods for colored anti-skid pavement typically rely on manual operation, such as workers manually spreading aggregate particles onto the road surface after the adhesive is applied. This method is not only labor-intensive and inefficient, but also makes it difficult to accurately control the density and uniformity of aggregate spreading, easily leading to aggregate waste. More importantly, manually spread aggregate often simply adheres to the adhesive surface, resulting in insufficient bonding and easy detachment during use, affecting the anti-skid effect and service life of the pavement. To overcome these shortcomings of the prior art, this application proposes an automatic paving equipment for colored anti-skid pavement. This equipment achieves automatic aggregate paving through mechanized and pneumatic conveying, aiming to improve construction efficiency, reduce aggregate waste, and enhance the bonding strength between aggregate and adhesive.

[0030] like Figures 1 to 3 The illustrated automatic color anti-slip pavement paving equipment includes a frame 1, and further includes:

[0031] Air compressor 4 is mounted on frame 1 and is used to output high-pressure air;

[0032] Connecting pipe 5, one end of which is connected to air compressor 4;

[0033] Diverter pipe 6 is connected to the other end of connecting pipe 5 and is used to divert high-pressure air.

[0034] Multiple delivery pipes 7, each delivery pipe 7 having one end connected to a branch pipe 6;

[0035] Multiple spray guns 10, each spray gun 10 is connected to the other end of a delivery pipe 7, and a nozzle 8 is fixedly installed at the end of the spray gun 10;

[0036] Multiple material tanks 2 are fixedly installed on the frame 1. The material tanks 2 are used to contain aggregate particles. Each material tank 2 is equipped with a connecting cover 3. The connecting cover 3 is used to connect the material tank 2 to the corresponding spray gun 10, so that the aggregate particles in the material tank 2 are sucked in when high-pressure air passes through the spray gun 10.

[0037] Compared with the existing technology of manually spreading aggregates, the automatic paving equipment for colored anti-skid pavement of this application has significant advantages. Existing technologies rely on manual operation, which is inefficient and difficult to guarantee uniformity, easily leading to aggregate waste. This application, however, uses mechanized and pneumatic conveying to achieve automatic and continuous aggregate paving, greatly improving construction efficiency and paving quality. Manually spread aggregates do not bond firmly with the adhesive and are prone to detachment. This application uses high-pressure gas generated by an air compressor 4 to spray aggregate particles at high speed from nozzles 8, allowing the aggregate particles to embed with a certain kinetic energy into the uncured MMA resin, thus forming a stronger mechanical bond, effectively solving the problem of aggregate detachment, and improving the anti-skid performance and durability of the pavement.

[0038] When using the automatic colored anti-skid pavement paving equipment of this application, the equipment is first moved to the starting position of the road section already coated with MMA resin. Aggregate particles are loaded into the hopper 2, and the hopper 2 is securely connected to the corresponding spray gun 10 via the connecting cover 3. The air compressor 4 mounted on the frame 1 is started. The air compressor 4 begins operation and outputs high-pressure gas. The high-pressure gas enters the distribution pipe 6 along the connecting pipe 5 and is distributed to various delivery pipes 7 within the distribution pipe 6. The high-pressure gas flows through the delivery pipes 7 to the spray gun 10 connected to its end. When the high-pressure gas flows at high speed through the interior of the spray gun 10, according to Bernoulli's principle, a local low pressure is generated in the area connected to the hopper 2. Under the action of this low pressure, the aggregate particles in the hopper 2 are drawn into the high-speed gas flow, forming a mixture of gas and aggregate particles. This mixture is then sprayed through the nozzle 8 of the spray gun 10 onto the road surface below, i.e., the uncured MMA resin layer. Workers can push the equipment from both sides of the frame 1, or connect external traction equipment such as cable reeling equipment via hooks 9 attached to the frame 1, allowing the equipment to move forward along the road track. During the movement, aggregate particles are continuously and uniformly sprayed onto the MMA resin and embedded into the resin due to the kinetic energy of the spray. The frame 1 provides overall support and a moving platform for the equipment, ensuring stable movement along the predetermined path. The air compressor 4 is the power source for the entire system, providing the necessary air pressure. Connecting pipes 5, branch pipes 6, and delivery pipes 7 form an efficient gas delivery and distribution network, ensuring that high-pressure gas is accurately delivered to each spray gun 10. The spray gun 10 is a key component for achieving aggregate intake and mixing with gas; its design directly affects the aggregate delivery efficiency and spraying effect. The tank 2 provides storage space for the aggregate, and the connecting cover 3 ensures that the aggregate is smoothly drawn into the spray gun 10. The nozzle 8 controls the spray shape and range of the aggregate mixture, contributing to uniform aggregate coverage on the road surface. Through this automated paving process, aggregate particles can be effectively embedded in MMA resin to form a strong bond, and the aggregate is randomly distributed, providing a high coefficient of friction for colored anti-slip pavement and ensuring the anti-slip effect of the pavement.

[0039] As one embodiment of this utility model, the frame 1 includes a frame structure welded from metal tubing.

[0040] In implementation, the frame 1 adopts a frame structure welded from metal tubing. Compared to other possible frame forms, such as structures made of bent sheet metal or bolted connections, it has the advantages of simple structure, convenient manufacturing, and relatively low cost. More importantly, this welded frame structure has high strength and stability, reliably supporting the weight of the equipment components and withstanding various dynamic loads and impacts during equipment movement. This ensures stable operation of the equipment even under complex road conditions, thereby improving the overall reliability and service life of the equipment.

[0041] As one embodiment of this utility model, the frame 1 is provided with wheels at all four corners of its bottom.

[0042] In practice, the frame 1 is equipped with wheels at all four corners of its bottom. Compared to designs without wheels or with wheels located elsewhere, this layout provides superior mobility. Positioning the wheels at the four corners of the frame's bottom ensures that the equipment's weight is evenly distributed across four support points, guaranteeing stability during movement and preventing tilting or swaying. This allows workers to more easily and stably move the frame 1 along the predetermined path, improving equipment maneuverability and ease of paving operations.

[0043] In one embodiment of this utility model, the diversion pipe 6 is arranged horizontally, and multiple delivery pipes 7 are arranged at intervals along the length of the diversion pipe 6.

[0044] In implementation, the diversion pipe 6 is arranged laterally with multiple conveying pipes 7 spaced apart along its length. This structural layout is crucial for achieving uniform aggregate paving. In this way, high-pressure gas from the air compressor 4 can be effectively distributed to multiple spray guns 10, ensuring that each spray gun 10 receives sufficient air pressure for aggregate intake and spraying. Simultaneously, the spaced conveying pipes 7 along the diversion pipe 6 allow the multiple spray guns 10 to form a spraying area in the lateral direction. As the equipment moves forward, a road surface of a certain width can be paved. Therefore, this technical solution ensures that aggregate particles are evenly and continuously spread on the road surface, avoiding areas of missed or repeated spraying, thus improving paving quality and efficiency.

[0045] As one embodiment of this utility model, the spray gun 10 includes a gun body and a connecting pipe. The connecting pipe is used to connect to the conveying pipe 7. One end of the gun body is connected to the connecting pipe, and the other end is connected to the nozzle 8. The material tank 2 is connected to the gun body through the connecting cover 3.

[0046] In practice, the spray gun 10 is the core component for achieving aggregate intake and spraying. The spray gun 10 consists of a gun body and a connecting pipe. The connecting pipe is designed to connect to the delivery pipe 7, thereby receiving high-pressure gas from the delivery pipe 7. One end of the gun body is connected to the connecting pipe, forming a channel for gas to enter the spray gun 10. The other end of the gun body is connected to the nozzle 8, through which the mixture of aggregate and gas is finally sprayed out. The material tank 2, used to hold aggregate particles, is connected to the gun body via a connecting cover 3. The connecting cover 3 ensures a sealed connection between the material tank 2 and the gun body and provides a channel for aggregate to enter the gun body from the material tank 2.

[0047] As one embodiment of this utility model, the frame 1 is provided with a hook 9.

[0048] Specifically, refer to Figure 2 As shown, one or more hooks 9 are provided at appropriate locations on the frame 1, such as the front end or side of the frame 1. Each hook 9 is a structural component for connecting an external traction device. As one possible implementation, the hook 9 can be a metal ring, a U-shaped hook, or other structure capable of reliably connecting cables or chains. The hook 9 is securely fixed to the structural component of the frame 1, for example, by welding or bolting, to ensure that it will not break or fall off under traction.

[0049] The frame 1 is equipped with hooks 9, providing an additional means of movement for this automatic colored anti-slip pavement paving equipment. Besides manual pushing via the wheels at the bottom, the hooks 9 connect to external traction equipment, such as cable winding equipment, enabling automated traction movement. This technical solution improves the equipment's automation level and is particularly suitable for long-distance paving operations or those requiring stable, uniform speed movement, expanding the equipment's application range and convenience.

[0050] In one embodiment of this utility model, the material tank 2 is made of transparent material.

[0051] The material tank 2 is a container used to hold aggregate particles. The tank body of the material tank 2 is made of a transparent material. This transparent material can be, for example, transparent plastic (such as polycarbonate, acrylic, etc.) or glass. By using a transparent material to manufacture the material tank 2, its internal condition can be directly observed with the naked eye.

[0052] The material hopper 2 is made of transparent material, providing a clear indication of aggregate levels compared to opaque hoppers. Workers can easily observe the remaining aggregate particles without opening the hopper lid or using other methods to check. This allows for timely assessment of whether aggregate needs to be replenished, preventing sudden work interruptions due to aggregate depletion or uneven paving caused by failure to replenish in time. This technical solution improves the ease of use and continuous operation capability of the equipment, helping to ensure smooth paving operations and stable paving quality.

[0053] As one embodiment of this utility model, the nozzle 8 is flat.

[0054] The nozzle 8 is flat, which, compared to round or other shaped nozzles, disperses the aggregate particles sprayed from the spray gun 10 into a fan-shaped or band-shaped spray pattern. Therefore, as the equipment moves along the road, the flat nozzle 8 achieves a wider coverage of aggregate particles in the lateral direction of the road surface and helps to evenly distribute the aggregate particles within the paved area, avoiding the problem of excessive aggregate accumulation in the spray center and insufficient aggregate at the edges that can occur with round nozzles. This technical solution improves the uniformity and coverage efficiency of aggregate paving by optimizing the nozzle shape, thereby enhancing the overall paving quality of colored anti-skid pavement.

[0055] Working principle of this utility model:

[0056] When using this type of paving device, after applying MMA resin to the road, the paving device is moved to the first end of the anti-slip road (i.e., the end where MMA resin is first applied), and then the aggregate particles are put into the material tank 2. The connecting cover 3 is then tightened onto the material pipe. Subsequently, the air compressor 4 on the frame 1 is controlled to run. The high-pressure air output by the air compressor 4 enters the diversion pipe 6 along the connecting pipe 5, and is then transported to each conveying pipe 7 by the diversion pipe 6. It then moves to the corresponding spray gun 10 through the conveying pipe 7. When the high-pressure air flows to the spray gun 10, it can generate low pressure to adsorb the aggregate particles in the material tank 2. Finally, the aggregate particles and high-pressure air are sprayed outward from the nozzle 8. At this time, the workers push the frame 1 along the road track from both sides of the frame 1.

[0057] During the movement of the frame 1, the aggregate particles are sprayed into the uncured MMA resin from the nozzle 8 by high-pressure air, allowing the aggregate particles to embed into the MMA resin and achieve relatively effective adhesion. The aggregate particles are randomly distributed, and large aggregate particles roll on the MMA resin, ensuring that the large aggregate particles are completely covered by the MMA resin, thus ensuring the adhesion effect. Finally, after the MMA resin is cured, it can achieve effective bonding between the aggregate and the MMA resin. At the same time, the randomly distributed aggregate can provide a high coefficient of friction for the colored anti-slip pavement, ensuring the anti-slip effect of the pavement.

[0058] In addition, when used on straight road sections, a cable winding device can be installed at the end of the road, and one end of the cable can be fixedly connected to the hook 9. Then, aggregate particles are put into the storage shell, and the air compressor 4 is started. Then, the cable winding device is controlled to wind up the cable, thereby pulling the frame 1 to move along the road direction, improving the automation level of this type of paving equipment.

[0059] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope. All such changes and modifications fall within the scope of protection claimed by this utility model, which is defined by the appended claims and their equivalents.
