Description

Technical Field

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

[0002] Road and bridge construction pavement maintenance equipment is a key component ensuring the stable quality of cement concrete pavements during the forming stage. Its water spraying maintenance method prevents early cracking of concrete by precisely controlling humidity and temperature. This equipment typically consists of a water storage system, a power pump unit, a spraying actuator, and an intelligent control system. The water storage system uses a corrosion-resistant water tank with a multi-stage filtration system to ensure the sprayed water is clean and free of impurities. The power pump unit uses frequency conversion technology to achieve stepless adjustment of output pressure to adapt to constant pressure water supply requirements under different pipe resistance conditions. The spraying actuator includes an adjustable fan-shaped nozzle array and a rotary spray gun combination. The nozzle structure, optimized through computational fluid dynamics, ensures that the water mist evenly covers the road surface, forming a water film coverage layer of controllable thickness. Modern maintenance equipment integrates an environmental monitoring module, using temperature and humidity sensors to collect real-time pavement microclimate data and combining it with a GPS positioning system to automatically switch between segmented maintenance strategies. Operationally, the equipment supports both manual control and preset program operation modes. It can perform targeted reinforcement maintenance on special areas such as bridge expansion joints, and can also complete large-scale automated roving spraying according to preset trajectories. This precise maintenance model can not only effectively inhibit the generation of plastic shrinkage cracks, but also avoid temperature stress damage by reducing the peak hydration heat, so that the concrete pavement can achieve more than 95% of the design strength formation rate within a 7-day maintenance cycle, significantly improving the overall durability and service life of road and bridge engineering.

[0003] In existing technologies, water spraying and maintenance equipment for road and bridge construction surfaces is typically fixedly installed on the surface of a vehicle, relying on the vehicle's movement to drive the spraying device. However, the water output pipes of such equipment are often rigidly fixed to the vehicle surface, and the spraying angle, height, and direction cannot be flexibly adjusted according to actual maintenance needs. Utility Model Content

[0004] The purpose of this utility model is to provide a road and bridge construction pavement maintenance device to solve the above-mentioned problems. It improves the problem that the water spraying maintenance equipment for road and bridge construction pavements is usually fixedly installed on the surface of the vehicle body, and relies on the movement of the vehicle to drive the water spraying device to operate. The water output pipe is often rigidly fixed to the surface of the vehicle body, and the spraying angle, height and direction cannot be flexibly adjusted according to the actual maintenance needs.

[0005] This utility model achieves the above objectives through the following technical solution: a road and bridge construction pavement maintenance device, comprising: Vehicle body; A water storage tank, which is installed in the truck bed of the vehicle body; An adjustment mechanism includes a rectangular slot, a toothed belt, gears, mounting bases, and a motor. There are multiple gears and mounting bases. The rectangular slot is formed on the surface of the vehicle body. Multiple gears are respectively installed at the four corners of the vehicle body. The toothed belt is meshed and driven by the multiple gears on the circumferential surface. The toothed belt is slidably connected in the rectangular slot. Multiple mounting bases are fixedly connected to the surface of the toothed belt. The mounting mechanism is provided in multiple sets, and each set of the mounting mechanism is connected to multiple mounting seats. Each set of the mounting mechanism includes a mounting block, a fixing block and an L-shaped tube. The fixing block is fixedly connected to one end of the mounting block and the L-shaped tube is fixedly connected inside the fixing block. The first water supply pipe is fixedly connected to the surface of the vehicle body and is connected to the water storage tank. A bend, which is fixedly connected to one end of the first water supply pipe; The diverter pipe is fixedly connected to one end of the bend pipe, and multiple nuts are rotatably connected to the surface of the diverter pipe, with each of the multiple nuts being threaded into multiple L-shaped pipes. The first pump body is installed inside the vehicle body and is connected to the first water supply pipe.

[0006] Preferably, each of the plurality of mounting blocks is rotatably connected to a screw, and the plurality of screws are threadedly connected to a plurality of mounting seats, and a handle is fixedly connected to the upper end of the screw.

[0007] Preferably, a second water supply pipe is installed on both sides of the surface of the vehicle body, and multiple second water supply pipes are connected to a water storage tank. A second pump body is installed inside the water storage tank, and the second pump body is connected to multiple second water supply pipes. Multiple second water supply pipes are respectively located on both sides of the water storage tank. When in use, the second water supply pipes are connected to the mounting mechanism installed on the side through bends, diverters, and nuts.

[0008] Preferably, a third water supply pipe is fixedly connected to the surface of the vehicle body. The third water supply pipe is located at the rear of the vehicle. A third pump body is installed inside the water tank. The third pump body is connected to the third water supply pipe. When in use, the third water supply pipe is connected to the mounting mechanism installed at the rear through a bend, a branch pipe, and a nut.

[0009] Preferably, when the L-shaped pipe is outputting water, the motor is controlled to run, and the sliding range of the toothed belt in the rectangular rotating groove is ±10cm. This range will not affect the use of the bend.

[0010] Preferably, the first water supply pipe, the third water supply pipe, and the plurality of second water supply pipes are sealed with threaded metal plugs when not in use.

[0011] Preferably, after the mounting block is removed from the mounting base, the motor is controlled to run, indirectly driving the toothed belt to rotate. At this time, the sliding range of the toothed belt is unrestricted, which is used to adjust the position of the mounting base.

[0012] The beneficial effects of this utility model are: 1. In this solution, the device employs a translation adjustment mechanism consisting of a toothed belt, gears, and a mounting base, combined with a lifting mechanism composed of a screw and mounting blocks. This allows the L-shaped pipe to move precisely within ±10cm in the horizontal direction while simultaneously achieving stepless vertical height adjustment. This three-dimensional adjustment capability enables the spraying device to flexibly adapt to road conditions with varying widths and longitudinal slopes, effectively solving the spraying dead zones and overlap problems inherent in traditional fixed pipelines. In particular, the second and third water supply pipe systems, which provide zoned control, enable independent and precise spraying to the sides and rear of the vehicle, significantly improving maintenance uniformity and water resource utilization.

[0013] 2. In this solution, the innovative nut and L-shaped pipe thread connection method, combined with standardized bends and branch pipes, enables rapid disassembly, assembly, and repositioning of the spraying unit. After removing the mounting block, the toothed belt can slide freely to reconfigure the mounting base layout, allowing the equipment to quickly adapt to the maintenance needs of different bridge and pavement surfaces. Simultaneously, the independent setup of the first, second, and third water supply pipeline systems, coupled with metal plug sealing protection, ensures both the availability of multiple operating modes and the cleanliness of the pipelines during non-use periods, significantly reducing equipment conversion time and maintenance costs.

[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. 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.

[0017] In practical implementation: such as Figures 1-5 As shown, the road and bridge construction pavement maintenance device includes: Vehicle body 1; Water tank 15 is installed in the truck bed of vehicle body 1; The adjustment mechanism includes a rectangular rotating groove 2, a toothed belt 3, a gear 4, a mounting base 5, and a motor. There are multiple gears 4 and mounting bases 5. The rectangular rotating groove 2 is opened on the surface of the vehicle body 1. Multiple gears 4 are respectively installed at the four corners inside the vehicle body 1. The toothed belt 3 is meshed and connected to the circumferential surface of multiple gears 4. The toothed belt 3 is slidably connected in the rectangular rotating groove 2. Multiple mounting bases 5 are all fixedly connected to the surface of the toothed belt 3. The installation mechanism is provided in multiple sets, and each set of installation mechanisms is connected to multiple mounting seats 5. Each set of installation mechanisms includes a mounting block 6, a fixing block 9, and an L-shaped tube 10. The fixing block 9 is fixedly connected to one end of the mounting block 6, and the L-shaped tube 10 is fixedly connected inside the fixing block 9. The first water supply pipe 14 is fixedly connected to the surface of the vehicle body 1 and is connected to the water storage tank 15. The bend 13 is fixedly connected to one end of the first water supply pipe 14; Diverter pipe 12 is fixedly connected to one end of bend pipe 13. Multiple nuts 11 are rotatably connected to the surface of diverter pipe 12, and the multiple nuts 11 are threadedly connected to multiple L-shaped pipes 10 respectively. The first pump body is installed inside the vehicle body 1 and is connected to the first water supply pipe 14.

[0018] In this embodiment, the spraying angle is flexibly adjusted through a movable spraying unit. The device includes a vehicle body 1, with a water tank 15 installed in the truck bed of the vehicle body 1. The key adjustment mechanism includes a rectangular rotating groove 2 formed on the surface of the vehicle body 1, a toothed belt 3 slidably connected within the rectangular rotating groove 2, multiple gears 4 respectively installed at the four corners of the vehicle body 1, and multiple mounting seats 5 fixedly connected to the surface of the toothed belt 3. The toothed belt 3 meshes with the multiple gears 4 and is driven by a motor. Multiple sets of mounting mechanisms are respectively connected to multiple mounting seats 5. Each set of mounting mechanisms includes a mounting block 6, a fixing block 9 fixedly connected to one end of the mounting block 6, and an L-shaped pipe 10 fixedly connected within the fixing block 9. A first water supply pipe 14 is fixed to the surface of the vehicle body 1 and communicates with the water tank 15. Its end is sequentially connected to a bend pipe 13 and a diversion pipe 12. Multiple nuts 11 rotatably connected to the surface of the diversion pipe 12 are threadedly connected to multiple L-shaped pipes 10. The first pump pumps water from the water storage tank 15 into the first water delivery pipe 14, and finally sprays it out through the L-shaped pipe 10. The adjustment mechanism can drive the mounting base 5 and the L-shaped pipe 10 to move as a whole, so as to achieve flexible adjustment of the spraying position.

[0019] like Figures 1-5 As shown, each of the multiple mounting blocks 6 is rotatably connected to a screw 7, and the multiple screws 7 are threadedly connected to multiple mounting seats 5 respectively. A handle 8 is fixedly connected to the upper end of the screw 7.

[0020] In this embodiment: each of the multiple mounting blocks 6 is rotatably connected to a screw 7, which is threadedly connected to the corresponding mounting base 5, and a handle 8 is fixedly connected to the upper end of the screw 7. By rotating the handle 8, the screw 7 can be driven to rotate, thereby causing the mounting block 6 to move the entire spraying unit up and down relative to the mounting base 5, realizing fine adjustment of the spraying height, and the mounting block 6 can be completely removed from the mounting base 5 when needed.

[0021] like Figures 1-5 As shown, a second water supply pipe 16 is installed on both sides of the surface of the vehicle body 1. Multiple second water supply pipes 16 are connected to a water storage tank 15. A second pump body is installed inside the water storage tank 15. The second pump body is connected to multiple second water supply pipes 16. Multiple second water supply pipes 16 are respectively located on both sides of the water storage tank 15. When in use, the second water supply pipes 16 are connected to the mounting mechanism installed on the side through a bend pipe 13, a diverter pipe 12, and a nut 11.

[0022] In this embodiment: Second water supply pipes 16 are installed on both sides of the surface of the vehicle body 1, and these second water supply pipes 16 are all connected to the water storage tank 15. A second pump body is installed in the water storage tank 15, which is dedicated to supplying water to the second water supply pipes 16. When in use, the second water supply pipes 16 are connected to the mounting mechanism installed on the side of the vehicle body through a bend 13, a branch pipe 12, and a nut 11, thereby realizing independent water spraying and maintenance of the road surface on both sides of the vehicle.

[0023] like Figures 1-5As shown, a third water supply pipe 17 is fixedly connected to the surface of the vehicle body 1. The third water supply pipe 17 is located at the rear of the vehicle. A third pump body is installed inside the water tank 15. The third pump body is connected to the third water supply pipe 17. When in use, the third water supply pipe 17 is connected to the mounting mechanism installed at the rear through a bend pipe 13, a diverter pipe 12, and a nut 11.

[0024] In this embodiment: a third water supply pipe 17 is fixedly connected to the surface of the vehicle body 1, and the third water supply pipe 17 is located at the rear of the vehicle. A third pump body is installed in the water tank 15, which is specifically for supplying water to the third water supply pipe 17. When in use, the third water supply pipe 17 is also connected to the mounting mechanism installed at the rear of the vehicle body through a bend 13, a branch pipe 12, and a nut 11, thereby realizing water spraying and maintenance of the road surface directly behind the vehicle.

[0025] like Figures 1-5 As shown, when the L-shaped pipe 10 is outputting water, the motor is controlled to run, and the sliding range of the toothed belt 3 in the rectangular rotating groove 2 is ±10cm. This range will not affect the use of the bend pipe 13.

[0026] In this embodiment: when the L-shaped pipe 10 is outputting water, the motor is controlled to run, and the sliding range of the toothed belt 3 within the rectangular rotating groove 2 is limited to ±10cm. This design ensures that the spraying position can be flexibly adjusted within a certain range to meet different coverage needs, while avoiding excessive pulling or twisting of the connected pipe components such as the bend pipe 13 due to excessive movement range, thus ensuring the reliability of the system during the adjustment process.

[0027] like Figures 1-5 As shown, the first water supply pipe 14, the third water supply pipe 17 and the plurality of second water supply pipes 16 are sealed with threaded metal plugs when not in use.

[0028] In this embodiment, the first water supply pipe 14, the third water supply pipe 17, and the multiple second water supply pipes 16 are sealed with threaded metal plugs when not in use. This design effectively prevents dust, debris, and other contaminants from entering the pipes, avoiding clogging of the nozzles or damage to the pump body, ensuring that the equipment remains clean during non-operation periods and is ready for normal use at any time.

[0029] like Figures 1-5 As shown, when the mounting block 6 is removed from the mounting base 5, the control motor runs, indirectly driving the toothed belt 3 to rotate. At this time, the sliding range of the toothed belt 3 is unrestricted, and it is used to adjust the position of the mounting base 5.

[0030] In this embodiment: when the mounting block 6 is removed from the mounting base 5, i.e., when the spraying unit is detached, the control motor runs, indirectly driving the toothed belt 3 to rotate. At this time, the sliding range of the toothed belt 3 is unrestricted. This mode allows for significant adjustments to the initial installation position of the mounting base 5 on the rectangular turntable 2, so that the entire spraying system can be rearranged according to different maintenance task requirements, enhancing the adaptability and configuration flexibility of the equipment.

[0031] It should be noted that the vehicle body 1, motor, first pump body, second pump body and third pump body used in this device are all existing technologies. The specific models of vehicle body 1, motor, first pump body, second pump body and third pump body used can be selected according to actual needs, and will not be elaborated on here.

[0032] In use, the operator first plans the spraying layout according to the maintenance requirements. If the initial position of the mounting base 5 needs to be adjusted, the mounting block 6 can be removed, and the motor can be started to drive the gear 4 to drive the toothed belt 3 to slide freely within the rectangular rotating groove 2 to the target position. During installation, the mounting block 6 and the mounting base 5 are threadedly fixed by rotating the handle 8 to drive the screw 7. The L-shaped pipe 10 is then connected to the corresponding diversion pipe 12 through the nut 11. During operation, the corresponding pumps are started: the first pump drives water to flow through the first water supply pipe 14, the bend pipe 13, and the diversion pipe 12 to the top L-shaped pipe 10; for lateral maintenance, the second pump is started to supply liquid through the second water supply pipe 16; for tail maintenance, the third pump is started to supply liquid through the third water supply pipe 17. During spraying, the motor can be controlled in real time to make the toothed belt 3 drive the mounting base 5 to move back and forth within a range of ±10cm to achieve dynamic sweeping spraying. The height of the L-shaped pipe 10 from the ground can be changed by rotating the handle 8 to adjust the screw 7. After completing the work, disassemble the L-shaped pipe 10 and seal the joints of the first water supply pipe 14, the second water supply pipe 16 and the third water supply pipe 17 with threaded metal plugs.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
