Description

Technical Field

[0001] This utility model relates to the field of spray coating equipment, specifically an intelligent scraping and spraying equipment for applying primer to running tracks. Background Technology

[0002] A running track is a dedicated venue for running competitions and training in track and field. It usually consists of one or more circular or straight tracks and can be indoors or outdoors. Before construction, the track needs to be sprayed with primer using a painting machine and then coated with a trowel.

[0003] Existing spray painting equipment basically consists of a handcart, a paint storage tank, a spray nozzle, and a scraper. The paint storage tank is mounted on top of the handcart, and the spray nozzle is located at the bottom of the handcart and is connected to the paint storage tank. To improve the intelligence of existing spray painting equipment, some manufacturers have added a telescopic cylinder to the handcart. This cylinder adjusts the height of the scraper, allowing it to be used on uneven surfaces and for coatings of varying thicknesses. This telescopic cylinder enhances the intelligence and practicality of the spray painting equipment. After the spray nozzle applies the paint from the storage tank to the ground, the scraper at the bottom of the handcart spreads the paint evenly across the surface. The paint is distributed on the runway surface to complete the initial coating. However, after the initial coating is completed, some paint will slide along the edge of the scraper, resulting in uneven paint thickness on both sides of the scraper edge. Currently, workers push the handcart again to move the scraper over the uneven coating area and scrape it to make it uniform. However, this requires additional workers to push the handcart multiple times to scrape the uneven coating on both sides of the scraper edge, which reduces the construction efficiency of the runway surface paint coating and increases the labor intensity of the workers to some extent. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an intelligent scraping and spraying equipment for running track primer. This solves the problem of requiring additional staff to push a handcart and make multiple movements to scrape the uneven coating thickness on both sides of the scraper edge, which reduces the construction efficiency of running track paint coating and increases the labor intensity of staff to some extent.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an intelligent scraping and spraying equipment for primer coating of running tracks, including a handcart, wherein a spraying mechanism and a driving mechanism are fixedly mounted on the top of the handcart, the output end of the driving mechanism extends out of the interior of the handcart, the driving mechanism is slidably connected to the handcart, and a scraper mechanism is fixedly mounted on the output end of the driving mechanism.

[0006] The scraper mechanism includes a power component. The top of the power component is fixedly connected to the bottom of the output end of the drive mechanism. A movable block is fixedly provided at the output end of the power component. A circular frame is fitted on the outer surface of the movable block. The movable block is rotatably connected to the circular frame. The outer surface of the output end of the drive component is rotatably connected to the inner surface of the circular frame. The top of the circular frame is fixedly connected to the bottom of the output end of the drive mechanism. Movable grooves are respectively opened on both sides of the outer surface of the circular frame. Connecting blocks are fixedly provided on both sides of the movable block. The two connecting blocks extend into the two movable grooves on the side away from the movable block. The two connecting blocks are slidably connected to the two movable grooves. A scraper for scraping paint is fixedly provided on the side of the two connecting blocks away from the movable block.

[0007] As a preferred technical solution of this utility model, the power component includes a motor, the top of the motor is fixedly connected to the bottom of the output end of the drive component, the output end of the motor extends into the interior of the circular frame and into the interior of the movable block, the outer surface of the motor output end is rotatably connected to the inner surface of the circular frame, and the outer surface of the motor output end is fixedly connected to the inner surface of the movable block.

[0008] As a preferred technical solution of this utility model, the driving mechanism includes a telescopic cylinder, the bottom of which is fixedly connected to the top of the handcart, the output end of which extends out of the handcart, and the outer surface of the output end of which is slidably connected to the inner surface of the handcart.

[0009] As a preferred technical solution of this utility model, a connecting plate is fixedly provided at the bottom of the output end of the telescopic cylinder, and the bottom of the connecting plate is fixedly connected to the top of the motor.

[0012] Compared with the prior art, this utility model provides an intelligent scraping and spraying equipment for applying primer to running tracks, which has the following beneficial effects:

[0013] After the spraying mechanism completes the bottom spraying and the scraper performs a preliminary scraping of the ground, the worker drives the power unit to rotate the movable block. This causes the circular block to drive the two scrapers through two connecting blocks, making the two scrapers move in opposite directions. Then, the worker can push the trolley along the ground after the preliminary scraping, allowing the trolley to move the scrapers to trim the painted edges on the ground, ensuring a smooth and neat edge of the runway primer coating. This structure allows for the simultaneous trimming of uneven paint coating on both sides of the scraper edge in a single operation, eliminating the need to push the trolley multiple times. This improves the construction efficiency of the runway ground paint coating and reduces the labor intensity of the workers to some extent. Attached Figure Description

[0019] 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.

[0020] Please see Figures 1-4In this embodiment: an intelligent scraping and spraying device for primer coating of running tracks includes a handcart 1. A spraying mechanism and a drive mechanism are fixedly mounted on the top of the handcart 1. The output end of the drive mechanism extends into the interior of the handcart 1 and is slidably connected to the handcart 1. A scraper mechanism is fixedly mounted on the output end of the drive mechanism. The scraper mechanism includes a power component, the top of which is fixedly connected to the bottom of the output end of the drive mechanism. A movable block 3 is fixedly mounted on the output end of the power component. A circular frame 2 is fitted onto the outer surface of the movable block 3, and the movable block 3 is rotatably connected to the circular frame 2. The outer surface of the output end of the drive component is rotatably connected to the inner surface of the circular frame 2. The top of the circular frame 2 is fixedly connected to the bottom of the output end of the drive mechanism. Movable grooves 4 are respectively opened on both sides of the outer surface of the frame 2. Connecting blocks 5 are respectively fixed on both sides of the movable block 3. The two connecting blocks 5 extend into the two movable grooves 4 on the side away from the movable block 3. The two connecting blocks 5 are slidably connected to the two movable grooves 4. The two connecting blocks 5 are respectively fixed on the side away from the movable block 3, and scrapers 6 for scraping paint are respectively fixed. The power component includes a motor 7. The top of the motor 7 is fixedly connected to the bottom of the output end of the drive component. The output end of the motor 7 extends into the interior of the circular frame 2 and into the interior of the movable block 3. The outer surface of the output end of the motor 7 is rotatably connected to the inner surface of the circular frame 2. The outer surface of the output end of the motor 7 is fixedly connected to the inner surface of the movable block 3.

[0021] The circular frame 2 is connected to the connecting plate 9 via the support block 10 to prevent the circular frame 2 from moving along with the drive of the motor 7, thus ensuring the normal operation of the scraper 6 rotation.

[0022] The drive mechanism includes a telescopic cylinder 8, the bottom of which is fixedly connected to the top of the handcart 1. The output end of the telescopic cylinder 8 extends out of the interior of the handcart 1, and the outer surface of the output end of the telescopic cylinder 8 is slidably connected to the inner surface of the handcart 1. A connecting plate 9 is fixedly provided at the bottom of the output end of the telescopic cylinder 8, and the bottom of the connecting plate 9 is fixedly connected to the top of the motor 7. Two support blocks 10 are fixedly provided at the top of the circular frame 2, and the two support blocks 10 are located on both sides of the motor 7. The tops of the two support blocks 10 are fixedly connected to the bottom of the connecting plate 9. The spraying mechanism includes a paint storage tank 11, the bottom of which is fixedly connected to the top of the handcart 1. A nozzle 12 communicating with the paint storage tank 11 is fixedly provided at the bottom of the handcart 1. The nozzle 12 can accurately complete the paint output through intelligent control.

[0023] When primer needs to be applied to areas with protruding stones, the operator drives the telescopic cylinder 8 to move. The telescopic cylinder 8 drives the motor 7 via the connecting plate 9, which in turn drives the scraper 6 via the circular block and connecting block 5. This allows for height adjustment of the scraper 6 to adapt to different ground heights and paint coatings, improving the intelligence of the painting equipment. When the trolley is initially moved on the ground, both scrapers 6 are in a horizontal position. After the first scraper 6 applies the initial coat of paint sprayed from the nozzle 12, the second scraper 6 will trim the paint on the section traversed by the first scraper 6, eliminating defects such as air bubbles and making the coating smoother and more uniform.

[0024] The working principle and usage process of this utility model are as follows: When primer spraying is required on the ground, the worker pushes the handcart 1 to move on the ground. When the handcart 1 moves, the paint in the paint storage tank 11 is sprayed onto the ground through the nozzle 12. Then, as the handcart 1 continues to move forward, it drives the scraper 6 to move, so that the scraper 6 scrapes the paint on the ground evenly, completing the initial scraping of the primer. Then, the worker starts the motor 7, so that the motor 7 drives the movable block 3 inside the circular frame 2 to move. The movable block 3 drives the connecting block 5 inside the two movable slots 4 to move. At the same time, the two connecting blocks 5 drive the two scrapers 6 to move, so that the two scrapers 6 move in opposite directions. Then, the worker can push the handcart 1 along the ground after the initial scraping to move it again, so that the handcart 1 drives the scraper 6 to trim the edges of the paint on the track ground, ensuring that the edges of the track primer coating are smooth and neat.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
