Description

Technical Field

[0001] This application relates to the field of road maintenance technology, and in particular to a road maintenance watering device for highway construction. Background Technology

[0002] Asphalt pavement refers to various types of road surfaces constructed by incorporating road-grade asphalt materials into mineral aggregates. Asphalt binders enhance the ability of paving aggregates to resist damage from traffic and natural factors, resulting in a smooth, dust-free, impermeable, and durable surface. Therefore, asphalt pavement is one of the most widely used high-grade pavements in road construction. While the asphalt structural layer itself falls under the category of flexible pavements, its base layer can also utilize rigid cement concrete or semi-rigid hydraulic materials in addition to flexible materials.

[0003] When paving roads, watering is required for maintenance. However, the width of roads varies. When the road is wide, the water truck needs to make two round trips to finish watering. When the road is narrow, the water truck will spray water outside the road surface, resulting in water waste. This is especially true for paving roads in mountainous areas where water collection is very inconvenient. Therefore, we have proposed a road maintenance watering device for highway construction. Summary of the Invention

[0004] This application provides a road surface maintenance watering device for highway construction to solve the problems mentioned in the background art.

[0005] To solve, or at least partially solve, the above-mentioned technical problems, this application provides a road surface maintenance watering device for highway construction, comprising:

[0006] A connecting frame is provided, with a first water spray housing and a second water spray housing respectively movably limited and inserted into the upper and lower sides of the front end of the connecting frame. A transmission device is provided between the first water spray housing and the second water spray housing. Multiple first nozzles are provided at equal intervals on the right side of the front end of the first water spray housing and the left side of the front end of the second water spray housing. Multiple second nozzles are provided at equal intervals on the left side of the front end of the first water spray housing and the right side of the front end of the second water spray housing. An adjusting sealing head is provided inside the second nozzle.

[0007] An adjusting rod is fixedly connected at one end to the adjusting sealing head and at the other end to the limiting adjusting block. The adjusting rod is inserted through the seal and movably inserted into the rear side plate of the corresponding first and second water spray housings. The adjusting rod is limited and inserted into the middle of the limiting frame.

[0008] Optionally, the transmission device consists of a rack, a gear, and a motor. There are two racks, which are fixedly connected to the opposite surfaces of the first sprinkler housing and the second sprinkler housing. A gear meshes between the racks, and the middle part of the gear is fixedly sleeved on the rotating shaft of the motor. The motor is fixedly connected to the inner side wall of the connecting frame.

[0009] Optionally, the second nozzle has a frustum-shaped water outlet in the middle, and a frustum-shaped adjusting sealing head is movably inserted into the frustum-shaped water outlet. A sealing rubber layer is fixedly sleeved on the outside of the adjusting sealing head.

[0010] Optionally, a limiting ring is fixedly sleeved on the side of the adjusting rod near the adjusting sealing head.

[0011] Optionally, the limiting ring has multiple protrusions fixedly connected in a ring array on one side near the adjusting sealing head, and a spring is sleeved on the outer side of the adjusting rod between the limiting ring and the side wall of the first sprinkler housing or the second sprinkler housing.

[0012] Optionally, the two ends of the limiting frame are fixedly connected to the rear side plate of the connecting frame by fixing rods, and the limiting frame has an open rectangular opening in the middle.

[0013] Optionally, the rear side of the internal movable adjustment rod of the rectangular opening is connected.

[0014] Optionally, the width of the limiting adjustment block is greater than the width of the rectangular opening, and the end face of the limiting adjustment block near the limiting frame is provided with an inclined surface.

[0015] Optionally, the rear end of the connecting frame is fixedly connected to the lower rear end of the water tank, the water tank is mounted on a transport vehicle, the rear sides of the first sprinkler housing and the second sprinkler housing are connected to the water tank via a water supply hose, and a water pump is provided in the middle of the water supply hose.

[0016] Optionally, a rubber sealing ring is provided at the insertion point of the adjusting rod into the rear side plate of the first sprinkler housing and the second sprinkler housing.

[0017] The technical solutions provided in this application have the following advantages compared with the prior art:

[0018] The device provided in this application embodiment starts the motor to drive the gear to rotate forward and backward, thereby causing the rack to move relative or oppositely, thus adjusting the unfolded length of the first and second sprinkler housings. When the first and second sprinkler housings move in opposite directions, the adjusting rod will disengage from the rectangular opening in sequence. When the adjusting rod disengages from the rectangular opening, the limiting adjusting block will no longer be able to limit the movement, and the spring will force the adjusting rod to move towards the second nozzle, thereby causing the adjusting sealing head to move towards the front of the second nozzle. This creates a gap in the side wall of the frustum-shaped water outlet inside the second nozzle, allowing water to spray out from the gap and sprinkle water on the road surface, thus adapting to watering and maintenance of roads of different widths.

[0036] Figure 5 This is a structural diagram of the limit frame of a road surface maintenance watering device for highway construction.

[0037] like Figures 1-5 As shown in the figure, this application provides a road surface maintenance watering device for highway construction, comprising:

[0038] The connecting frame 3 has a first water spray housing 4 and a second water spray housing 5 that are movably limited and inserted into the upper and lower sides of its front end, respectively. A transmission device is provided between the first water spray housing 4 and the second water spray housing 5. Multiple first nozzles 6 are provided at equal intervals on the right side of the front end of the first water spray housing 4 and the left side of the front end of the second water spray housing 5. Multiple second nozzles 7 are provided at equal intervals on the left side of the front end of the first water spray housing 4 and the right side of the front end of the second water spray housing 5. An adjusting sealing head 18 is provided inside the second nozzle 7.

[0039] Adjusting rod 9, one end of which is fixedly connected to the adjusting sealing head 18, and the other end of which is fixedly connected to the limiting adjusting block 10. The adjusting rod 9 is inserted through the sealing and movably inserted into the rear side plate of the corresponding first water spray housing 4 and second water spray housing 5. The adjusting rod 9 is inserted into the middle of the limiting frame 11 for limiting.

[0040] Specifically: the first nozzle 6 can be any commercially available nozzle. The first nozzle 6 is arranged on the right and left sides of the first sprinkler housing 4 and the second sprinkler housing 5, respectively, and is equidistant from each other, so that the first sprinkler housing 4 and the second sprinkler housing 5 are contracted to the following size: Figure 1 When in the indicated state, water can be sprayed evenly onto the road surface. When the first water spray housing 4 and the second water spray housing 5 are displaced in opposite directions and the width of the first water spray housing 4 and the second water spray housing 5 is adjusted, the second nozzle 7 will open in sequence.

[0041] like Figure 3 As shown: The transmission device consists of a rack 15, a gear 16 and a motor. There are two racks 15, which are fixedly connected to the opposite surfaces of the first sprinkler housing 4 and the second sprinkler housing 5. The gear 16 is meshed between the racks 15. The middle part of the gear 16 is fixedly sleeved on the rotating shaft of the motor, and the motor is fixedly connected to the inner side wall of the connecting frame 3.

[0042] Specifically: the starter motor drives the gear 16 to rotate in both directions, thereby causing the rack 15 to move in opposite directions, thus adjusting the length of the first sprinkler housing 4 and the second sprinkler housing 5 when they are extended or shortened.

[0043] like Figure 2 As shown: The second nozzle 7 has a frustum-shaped water outlet 20 in the middle, and a frustum-shaped adjusting sealing head 18 is movably inserted into the frustum-shaped water outlet 20. A sealing rubber layer 19 is fixedly sleeved on the outside of the adjusting sealing head 18.

[0044] Specifically, the sealing rubber layer 19 can increase the sealing degree of the sealing frustum-shaped outlet 20 of the adjusting sealing head 18.

[0045] like Figure 2 and Figure 4 As shown: The adjusting rod 9 is externally fixedly sleeved with a limiting ring 13 on the side near the adjusting sealing head 18.

[0046] The limiting ring 13 has multiple protrusions fixedly connected in a ring array on one side near the adjusting sealing head 18. A spring 14 is sleeved on the outer side of the adjusting rod 9 between the limiting ring 13 and the side wall of the first water spray housing 4 or the second water spray housing 5.

[0047] Specifically: the limiting ring 13 can limit the displacement of the adjusting rod 9, the protrusion can allow liquid to enter the interior of the second nozzle 7, and the spring 14 is always in a compressed state.

[0048] like Figure 2 and Figure 5 As shown: The two ends of the limiting frame 11 are fixedly connected to the rear side plate of the connecting frame 3 by fixing rods, and the middle of the limiting frame 11 has an open rectangular opening 17.

[0049] The rear side of the internal movable adjustment rod 9 of the rectangular opening 17.

[0050] Specifically: The rectangular opening 17 is for inserting the adjusting rod 9.

[0051] like Figure 2 As shown: the width of the limiting adjustment block 10 is greater than the width of the rectangular opening 17, and the end face of the limiting adjustment block 10 near the limiting frame 11 is provided with an inclined surface.

[0052] Specifically, when the first water spray housing 4 and the second water spray housing 5 are displaced relative to each other, the inclined surface can cause the limit adjustment block 10 to move again to the rear end face of the limit frame 11.

[0053] like Figure 2As shown: The rear end of the connecting frame 3 is fixedly connected to the lower rear end of the water tank 2. The water tank 2 is mounted on the transport vehicle 1. The rear sides of the first water spray housing 4 and the second water spray housing 5 are connected to the water tank 2 through a water supply hose 8, and a water pump is provided in the middle of the water supply hose 8.

[0054] Specifically: In order to store water, the water pump inside water tank 2 is an existing pump on the market, which is electrically controlled.

[0055] like Figure 2 As shown: A rubber sealing ring 12 is provided at the insertion point of the adjusting rod 9 with the rear side plate of the first water spray housing 4 and the second water spray housing 5.

[0056] Specifically: the rubber sealing ring 12 can seal the insertion point of the adjusting rod 9.

[0057] When using the equipment, first fill the water tank 2 with enough water. The upper end of the water tank 2 is equipped with a liquid inlet, and the water pump on the water supply hose 8 is controlled by a switch and driven by electricity. The switch is located in the cab of the transport vehicle 1. When it is necessary to sprinkle water on the road, start the water pump to draw water from the water tank 2 into the first sprinkler housing 4 and the second sprinkler housing 5. Then, water is sprayed out through the first nozzle 6 and the opened second nozzle 7 to sprinkle water on the road.

[0058] To adjust the unfolded lengths of the first sprinkler housing 4 and the second sprinkler housing 5 to meet the sprinkling requirements of roads with different widths, the motor is activated by turning on the switch. This drives the gear 16 to rotate in both directions, causing the rack 15 to move relative to or in opposite directions. This allows for adjustment of the unfolded lengths of the first sprinkler housing 4 and the second sprinkler housing 5. When the first sprinkler housing 4 and the second sprinkler housing 5 move in opposite directions, the adjusting rod 9 will sequentially disengage from the rectangular opening 17. When the adjusting rod 9 disengages from the rectangular opening 17, the limiting adjusting block 10 will no longer be able to limit its movement, and the spring 14 will force the adjusting rod 9 to move towards the second nozzle 7. This causes the adjusting sealing head 18 to move towards the front of the second nozzle 7, creating a gap in the side wall of the frustum-shaped water outlet 20 inside the second nozzle 7. Water then sprays out from the gap to water the road surface. The limiting ring 13 limits the displacement of the adjusting rod 9, controlling the size of the gap. When the first water spray housing 4 and the second water spray housing 5 retract relative to each other, the inclined surface of the limiting adjusting block 10 forces the limiting adjusting block 10 to move again to the rear end of the limiting frame 11, causing the adjusting rod 9 to move backward. This causes the adjusting sealing head 18 to move backward, sealing the corresponding frustum-shaped water outlet 20, and thus sealing the second nozzle 7 in sequence.

[0059] The above description is merely a specific embodiment of this application, enabling those skilled in the art to understand or implement this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features claimed in this application.
