Description

Technical Field

[0001] This utility model relates to the field of highway maintenance technology, and in particular to a water-retaining spraying device for highway maintenance. Background Technology

[0002] Highway maintenance is a crucial aspect of ensuring safe and smooth road traffic. By repairing and maintaining roads, their service life can be extended, and water spraying is also an important method for road surface maintenance.

[0003] Existing road spraying equipment typically uses nozzles with a fixed length range. However, road widths vary, making it inconvenient to spray maintenance sprays on roads of different widths. Sometimes, repeated operation is required, which consumes extra time and indirectly wastes water resources. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a water-retaining spraying device for highway maintenance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A water-retaining spraying device for highway maintenance includes a triangular base and a main spraying pipe. Two identical rotating frames are rotatably connected to the hypotenuse of the triangular base. A horizontally positioned main spraying pipe is fixedly connected to the ends of the two rotating frames. A crossbar is fixedly connected between the tops of the two rotating frames. A swing rod is rotatably connected to the hypotenuse of the triangular base between the two rotating frames. The end of the swing rod is fixedly connected to one side of the crossbar. Hollow connecting columns are fixedly connected to both ends of the main spraying pipe. A retaining ring is provided at the end of the inner wall of the connecting column. A ball valve is movably connected to the side of the retaining ring near the main spraying pipe. A spring abuts against the ball valve and the main spraying pipe. It also includes a secondary spray pipe, one end of which has a connecting groove adapted to the connecting column, and several nozzles are fixedly installed on one side of the secondary spray pipe, with the nozzles connected to the connecting groove.

[0006] Preferably, the two right-angled sides of the triangular base are fixedly installed on the mounting seat, and the mounting seat is fixedly installed at the rear of the water spraying and maintenance vehicle.

[0007] Preferably, the rotating frame has a hollow groove at its center, and several water pipe frames are fixedly connected inside the hollow groove.

[0008] Preferably, a number of nozzles are fixedly installed on the side of the main spray pipe away from the triangular base, and two water pipe connectors are fixedly installed on the other side of the main spray pipe, which are respectively inserted into two hollow grooves. The water pipe connectors are connected to each nozzle through the channel inside the main spray pipe.

[0009] Preferably, the inclined side of the triangular base on one side of the swing rod is fixedly connected to an inclined fixing frame, a motor is fixedly installed on the top of the fixing frame, the output shaft of the motor is fixedly connected to a connecting rod, and a rotating block is rotatably connected to the end of the connecting rod, and the rotating block is slidably connected to the swing rod.

[0010] Preferably, the main spray pipes on both sides of the connecting column have square holes on their sidewalls, and the auxiliary spray pipes are fixedly connected to two blocks that are adapted to the square holes at one end near the connecting groove. The blocks and the square holes have threaded holes on their sidewalls.

[0011] Preferably, a pin is fixedly connected to the inner wall of the connecting groove by a bracket, and the diameter of the pin is smaller than the diameter of the retaining ring.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a secondary spray pipe to spray water onto the road surface via the main spray pipe and nozzles. When the road surface width exceeds the width of the main spray pipe, a secondary spray pipe can be installed on one or both sides of the main spray pipe. Before the secondary spray pipe is installed, the ball valve is kept closed by the combined action of spring force and water pressure, preventing leakage at the connection point. When the secondary spray pipe is installed, the pin pushes the ball valve to disengage from the retaining ring, connecting the groove and the main spray pipe. This expands the spraying range, eliminating the need for repeated spraying, simplifying operation, saving water resources, and reducing operation time.

[0013] This invention, by setting up a swing frame and a motor, allows the rotating block to be rotatably connected to the connecting rod while simultaneously slidingly connected to the swing rod. As the motor rotates, it drives the connecting rod to rotate, causing the rotating block to make circular motion. At the same time, the swing rod can swing left and right around the hypotenuse of the triangular base. This swinging motion can adjust the spraying angle of the main spray pipe, facilitating water retention operations on different road sections. It can also continuously swing, allowing the main spray pipe and nozzles to spray water onto the road in a swinging motion to achieve sufficient water retention. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-5 A water-retaining spraying device for highway maintenance includes a triangular base 2 and a main spraying pipe 5. Two identical rotating frames 3 are rotatably connected to the hypotenuse of the triangular base 2. A horizontally arranged main spraying pipe 5 is fixedly connected to the ends of the two rotating frames 3. A crossbar 8 is fixedly connected between the tops of the two rotating frames 3. A swing rod 13 is rotatably connected to the hypotenuse of the triangular base 2 between the two rotating frames 3. The end of the swing rod 13 is fixedly connected to one side of the crossbar 8. Hollow connecting columns 14 are fixedly connected to both ends of the main spraying pipe 5. A retaining ring 17 is provided at the end of the inner wall of the connecting column 14. A ball valve 18 is movably connected to the side of the retaining ring 17 near the main spraying pipe 5. A spring 16 abuts against the ball valve 18 and the main spraying pipe 5. It also includes a secondary spray pipe 19, one end of which has a connecting groove 20 adapted to the connecting post 14. Several nozzles 6 are fixedly installed on one side of the secondary spray pipe 19, and the nozzles 6 are connected to the connecting groove 20. Water is sprayed onto the road surface for maintenance through the main spray pipe 5 and the nozzles 6. When the road surface width is greater than the width of the main spray pipe 5, a secondary spray pipe 19 can be added to one or both sides of the main spray pipe 5. Before the secondary spray pipe 19 is added, the ball valve 18 is kept closed by the combined action of the spring 16 and water pressure, so that the connecting post 14 will not leak. When the secondary spray pipe 19 is added, the pin 22 pushes the ball valve 18 to disengage from the retaining ring 17, and the channel between the connecting groove 20 and the main spray pipe 5 is connected. At this time, the spraying range can be expanded, eliminating the need for repeated spraying, saving water resources and reducing operation time.

[0018] As a technical optimization of this utility model, the two right-angled sides of the triangular base 2 are fixedly installed on the mounting seat 1, and the mounting seat 1 is fixedly installed at the rear of the water spraying and maintenance vehicle. The mounting seat 1 is fixed to the water spraying and maintenance vehicle.

[0019] As a technical optimization of this utility model, the rotating frame 3 has a hollow groove in the center, and several water pipe brackets 4 are fixedly connected in the hollow groove. The water pipe brackets 4 are used to limit the water outlet pipe. When the rotating frame 3 swings, the water outlet pipe shakes too much and causes it to fall off the water pipe connector 7.

[0020] As a technical optimization of this utility model, several nozzles 6 are fixedly installed on the side of the main spray pipe 5 away from the triangular base 2, and two water pipe connectors 7 are fixedly installed on the other side of the main spray pipe 5, each passing through a hollow groove. The water pipe connectors 7 are connected to each nozzle 6 through a channel inside the main spray pipe 5. The water pipe connectors 7 are connected to the water outlet pipe of the water tank of the water sprinkler maintenance vehicle, and the water in the water tank is sprayed onto the road surface through the nozzles 6 via a water pump.

[0021] As a technical optimization of this utility model, a tilted fixing frame 9 is fixedly connected to the inclined side of the triangular base 2 on one side of the swing rod 13. A motor 10 is fixedly installed on the top of the fixing frame 9. A connecting rod 11 is fixedly connected to the output shaft of the motor 10. A rotating block 12 is rotatably connected to the end of the connecting rod 11. The rotating block 12 is slidably connected to the swing rod 13. Since the rotating block 12 is rotatably connected to the connecting rod 11 and slidably connected to the swing rod 13, the rotation of the motor 10 drives the connecting rod 11 to rotate, which in turn drives the rotating block 12 to make a circular motion. At the same time, the swing rod 13 can swing left and right around the inclined side of the triangular base 2. This swing can adjust the spray angle of the main spray pipe 5, which is convenient for water retention operations on different road sections. It can also swing continuously so that the main spray pipe 5 and the nozzle 6 can swing and spray the road to achieve sufficient water retention.

[0022] As a technical optimization of this utility model, square holes 15 are provided on the side walls of the main spray pipes 5 on both sides of the connecting column 14. Two square blocks 21 that are adapted to the square holes 15 are fixedly connected to one end of the auxiliary spray pipe 19 near the connecting groove 20. Threaded holes are provided on the side walls of the square blocks 21 and the square holes 15. The use of the square holes 15 and the square blocks 21 facilitates the positioning and connection between the auxiliary spray pipe 19 and the main spray pipe 5, and also allows for fixation by locking screws into the threaded holes.

[0023] As a technical optimization of this utility model, a pin 22 is fixedly connected to the inner wall of the connecting groove 20 by a bracket. The diameter of the pin 22 is smaller than the diameter of the retaining ring 17. When the auxiliary spray pipe 19 is connected to the main spray pipe 5, the pin 22 can push the ball valve 18 away from the retaining ring 17, and at this time, the auxiliary spray pipe 19 and the main spray pipe 5 are connected.

[0024] In use, the mounting base 1 is fixedly installed at the rear of the water spraying and maintenance vehicle. The water spraying and maintenance vehicle is equipped with a water tank. The water outlet pipe of the water tank is inserted into each water pipe bracket 4 of the two rotating frames 3. The end of the water outlet pipe is threadedly connected to the water pipe connector 7. The water pump in the water tank is started, and water is pumped into the water pipe connector 7 and sprayed from each nozzle 6. During this process, the water pressure and the spring 16 work together to push the ball valve 18 to close the retaining ring 17. At this time, the motor 10 can be started. Since the rotating block 12 is rotatably connected to the connecting rod 11 and slidably connected to the swing rod 13, the rotation of the motor 10 drives the connecting rod 11 to rotate, which in turn drives the rotating block 12 to make a circular motion. At the same time, the swing rod 13 can swing left and right around the hypotenuse of the triangular base 2. This can be achieved by synchronously driving the two rotating frames 3 and the main spray pipe 5 to swing left and right through the crossbar 8. This swing can adjust the spray angle of the main spray pipe 5, or it can swing continuously so that the main spray pipe 5 and the nozzle 6 can swing and spray the road to achieve sufficient water retention.

[0025] If the road width is greater than the width of the main spray pipe 5, an auxiliary spray pipe 19 can be installed on one or both sides of the main spray pipe 5. Align the two square blocks 21 at one end of the auxiliary spray pipe 19 with the two square holes 15 on one side of the main spray pipe 5, and push the auxiliary spray pipe 19 so that the blocks 21 are inserted into the square holes 15. During the pushing process, the pin 22 abuts against the ball valve 18 and pushes the ball valve 18 to overcome the force of the spring 16 and move away from the retaining ring 17. Finally, the blocks 21 are completely inserted into the square holes 15. Use screws to fix the blocks 21 in the threaded holes, and the connecting groove 20 is also connected to the channel of the main spray pipe 5. At this time, the water pump can pump water into the nozzles 6 on the auxiliary spray pipe 19 and spray it out, increasing the spraying range.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
