Description

Technical Field

[0001] This utility model relates to the field of road maintenance technology, and in particular to a road maintenance spraying device. Background Technology

[0002] After the cement concrete pavement is laid, it should be cured promptly. In the initial curing stage, to prevent the cement concrete from being exposed to sun and rain, a curing agent should be sprayed. When using a curing agent spray, the spray thickness must be sufficient to ensure the formation of a curing film.

[0003] For example, patent application number CN202320432491.1 discloses a road maintenance spraying device, including a frame device for connecting and fixing a water truck, and a swinging device installed on one side of the frame device for meshing and swinging. Two spraying devices for spraying road maintenance are symmetrically installed on both sides of the swinging device. The swinging device includes a driven gear, a fixing frame is installed on one side of the driven gear, and two clearance grooves are symmetrically arranged on both sides of the fixing frame. The spraying device includes a water supply pipe, and several nozzles are evenly installed at the bottom of the water supply pipe, with the nozzles at a 45-degree downward angle to the horizontal. This multi-head spraying configuration with left and right swinging facilitates swinging to one side of the water truck for spraying, ensuring comprehensive spraying.

[0004] Some sprinkler systems improve watering efficiency by extending the water pipe. However, the increased length of the water pipe causes the overall center of gravity of the sprinkler system to shift outward. Especially when it is rotated to the side of the sprinkler truck, the force on one side of the frame increases significantly, which can easily lead to loosening of the connection between the system and the sprinkler truck, or even cause the entire system to tilt, affecting operational safety. Utility Model Content

[0005] To address the aforementioned problems, this utility model proposes a road maintenance spraying device to overcome the shortcomings of existing systems.

[0006] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a road maintenance spraying device, including a transmission box, an upper support plate above the transmission box, a lower support plate below the transmission box, and the upper and lower support plates are fixedly connected to support blocks provided at the upper and lower ends of the transmission box.

[0007] A first rotating arm is provided between the transmission box and the upper support plate. The first rotating arm is rotatably connected to the upper support plate and the transmission box. A second rotating arm is provided between the transmission box and the lower support plate. The second rotating arm is rotatably connected to the lower support plate and the transmission box. A spray pipe is provided at one end of the first rotating arm and the second rotating arm.

[0008] The transmission box is equipped with a drive unit, which is connected to the first rotating arm and the second rotating arm to drive the first rotating arm and the second rotating arm to rotate relative to the transmission box, thereby switching the first rotating arm and the second rotating arm to the open state or the retracted state.

[0009] A further improvement is that the driving component includes a motor, a worm gear, and two worm wheels. The motor is fixedly mounted on the outside of the transmission box, the worm wheels are rotatably mounted on the inside of the transmission box, the worm gear is placed between the two worm wheels and meshes with the two worm wheels, the output end of the motor is fixedly connected to the worm gear, and the two worm wheels are respectively fixedly connected to the first rotating arm and the second rotating arm through a connecting shaft.

[0010] A further improvement is that the spray pipe includes a spray rod, which is detachably connected to the first rotating arm and the second rotating arm. Multiple spray heads are provided on the outside of the spray rod, and a guide pipe is provided at one end of the spray rod near the transmission box. The guide pipe is connected to the spray heads.

[0011] A further improvement is that: a connecting seat is provided at one end of the spray rod near the transmission box, the connecting seat is fixedly connected to the spray rod, and multiple fixing bolts are mounted on the connecting seat. The fixing bolts pass through the connecting seat and are threadedly connected to the bolt holes opened on the outer sides of the first and second rotating arms.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a road maintenance spraying device, including a transmission box 1, an upper support plate 2 above the transmission box 1, a lower support plate 3 below the transmission box 1, and the upper support plate 2 and the lower support plate 3 are fixedly connected to the support blocks 4 located at the upper and lower ends of the transmission box 1.

[0024] A first rotating arm 5 is provided between the transmission box 1 and the upper support plate 2. The first rotating arm 5 is rotatably connected to the upper support plate 2 and the transmission box 1. A second rotating arm 6 is provided between the transmission box 1 and the lower support plate 3. The second rotating arm 6 is rotatably connected to the lower support plate 3 and the transmission box 1. A spray pipe is provided at one end of the first rotating arm 5 and the second rotating arm 6.

[0025] The transmission box 1 is equipped with a driving component inside. The driving component is connected to the first rotating arm 5 and the second rotating arm 6 for driving the first rotating arm 5 and the second rotating arm 6 to rotate relative to the transmission box 1, thereby switching the first rotating arm 5 and the second rotating arm 6 to the open state or the retracted state.

[0026] The support block 4 should be positioned outside the unfolding and retracting paths of the first rotating arm 5 and the second rotating arm 6, so as to provide support and connection while avoiding contact with the first rotating arm 5 and the second rotating arm 6.

[0027] The spraying device is installed at the rear of the mobile trolley. The spray pipes on the first rotating arm 5 and the second rotating arm 6 are connected to a water pump. During maintenance, the drive unit controls the rotation of the first rotating arm 5 and the second rotating arm 6, so that the first rotating arm 5 and the second rotating arm 6 are in the open state, and the two spray pipes are extended to spray a large area of ​​the road surface. When passing through narrow areas, the drive unit controls the first rotating arm 5 and the second rotating arm 6 to rotate in opposite directions, so that the first rotating arm 5 and the second rotating arm 6 are retracted, and the two spray pipes retract synchronously, ensuring that the spraying device can pass smoothly.

[0028] Because the first rotating arm 5 and the second rotating arm 6 are staggered, the design length of the first rotating arm 5 and the second rotating arm 6 can be further increased, and there will be no collision between them, thereby balancing the counterweight of the spray tube and reducing the support burden of the transmission box 1. Furthermore, there will be no collision between the first rotating arm 5 and the second rotating arm 6 when they are extended and retracted.

[0029] Regarding the driver:

[0030] The driving component includes a motor 10, a worm gear 17, and two worm wheels 16. The motor 10 is fixedly mounted on the outside of the transmission box 1, the worm wheels 16 are rotatably mounted on the inside of the transmission box 1, the worm gear 17 is positioned between the two worm wheels 16 and meshes with the two worm wheels 16, the output end of the motor 10 is fixedly connected to the worm gear 17, and the two worm wheels 16 are fixedly connected to the first rotating arm 5 and the second rotating arm 6 respectively through the connecting shaft 7.

[0031] Motor 10 controls the worm 17 to rotate. During the rotation of the worm 17, it meshes with two worm wheels 16. Since the worm 17 is located between the two worm wheels 16, when the worm 17 rotates, the two worm wheels 16 will rotate in opposite directions under the drive of the worm 17, thereby completing the unfolding and retraction control of the first rotating arm 5 and the second rotating arm 6.

[0032] Regarding sprinkler pipe fittings:

[0033] The spray pipe fitting includes a spray rod 8, which is detachably connected to the first rotating arm 5 and the second rotating arm 6. Multiple spray heads 9 are provided on the outer side of the spray rod 8. A guide pipe 13 is provided at the end of the spray rod 8 near the transmission box 1, and the guide pipe 13 is connected to the spray heads 9. The end of the guide pipe 13 away from the spray rod 8 is connected to the pump of the mobile trolley. The pump draws the maintenance liquid from the water tank into the guide pipe 13, and then sprays it onto the road surface through the spray heads 9 on the outer side of the spray rod 8, completing the road surface maintenance work.

[0034] In a preferred embodiment, a connecting seat 14 is provided at one end of the spray rod 8 near the transmission box 1. The connecting seat 14 is fixedly connected to the spray rod 8, and multiple fixing bolts 15 are mounted on the connecting seat 14. The fixing bolts 15 pass through the connecting seat 14 and are threadedly connected to bolt holes opened on the outer sides of the first rotating arm 5 and the second rotating arm 6. When the spray rod 8 is removed from the first rotating arm 5 and the second rotating arm 6 for replacement, the fixing bolts 15 are rotated to unscrew them from the bolt holes on the outer sides of the first rotating arm 5 and the second rotating arm 6.

[0035] In the preferred embodiment, a hanging ring 12 is provided on the side of the upper support plate 2 and the lower support plate 3 away from the transmission box 1. The hanging ring 12 is fixedly connected to the upper support plate 2 and the lower support plate 3, and the guide pipe 13 passes through the hanging ring 12. The hanging ring 12 limits the guide pipe 13 to prevent it from falling to the ground when the spray bar 8 is deployed.

[0036] The spraying device is fixed to the mobile trolley using a bolt connection. Multiple mounting brackets 11 are located on the side of the transmission box 1 furthest from the motor 10. These mounting brackets 11 are fixedly connected to the transmission box 1, and each mounting bracket 11 has several connection holes. Connecting bolts are mounted on the brackets outside the trolley body. These bolts align with the connection holes on the mounting brackets 11, and after tightening with nuts, the mounting brackets 11 are fixed to the mobile trolley.

[0037] How this application works:

[0038] The spraying device is installed at the rear of the mobile trolley. The spray pipes on the first rotating arm 5 and the second rotating arm 6 are connected to a water pump. During maintenance, the drive unit controls the rotation of the first rotating arm 5 and the second rotating arm 6, so that the first rotating arm 5 and the second rotating arm 6 are in the open state, and the two spray pipes are extended to spray a large area of ​​the road surface. When passing through narrow areas, the drive unit controls the first rotating arm 5 and the second rotating arm 6 to rotate in opposite directions, so that the first rotating arm 5 and the second rotating arm 6 are retracted, and the two spray pipes retract synchronously, ensuring that the spraying device can pass smoothly.
