Description

Technical Field

[0001] This application relates to the technical field of road maintenance, and in particular to a concrete road maintenance device. Background Technology

[0002] After the concrete pavement is poured and formed, it needs to be watered for curing to ensure the strength of the concrete pavement and to prevent shrinkage and cracking caused by excessive evaporation of moisture.

[0003] Currently, maintenance vehicles are generally used for the maintenance of concrete roads. However, when encountering narrow roads, such as sidewalks and park roads, it is usually necessary to manually drag water hoses for spraying or manually push handcarts for maintenance. The handcarts are equipped with horizontal water hoses at the bottom, and multiple nozzles are installed at intervals on the water hoses. When the handcart is pushed, the nozzles spray water to maintain the road surface below.

[0004] In related technologies, dragging water hoses for spraying is labor-intensive and inefficient; while using a handcart for maintenance is troublesome and inefficient because the length of the water hose is fixed. When the road width is different from the width of the handcart, the handcart needs to be pushed back and forth. This may also lead to excessive watering in the intersecting parts of the road due to the different road widths. Utility Model Content

[0005] In order to accurately water and maintain the road surface and improve maintenance efficiency, this application provides a concrete road surface maintenance device.

[0006] This application provides a concrete pavement curing device, which adopts the following technical solution:

[0007] A concrete pavement maintenance device includes a base, a push rod disposed at the rear end of the base, a water tank and a water pump disposed on the base, and a spray pipe rotatably disposed below the base, a plurality of nozzles disposed on the spray pipe, and a drive assembly for driving the spray pipe to rotate. Two spray pipes are provided, and the spray pipes are connected to the water tank via the water pump. The two spray pipes can simultaneously rotate towards the center line of the base at an acute angle, and can also simultaneously rotate away from the center line of the base at a flat angle. The drive assembly can drive both spray pipes to rotate simultaneously.

[0008] By adopting the above technical solution, this concrete pavement maintenance device can flexibly adjust the angle of the spray pipes to adapt to the maintenance needs of roads of different widths. Specific effects include: both spray pipes can simultaneously rotate towards the center line of the base to form an acute angle, thereby reducing the water mist coverage area when the road is narrow, avoiding water waste; simultaneously, when the coverage area is small, the pavement receives more water per unit time, increasing the speed of maintenance; both spray pipes can also simultaneously rotate away from the center line of the base to form a flat angle, thereby expanding the water mist coverage area when the road is wide, improving maintenance efficiency. This angle adjustment function effectively solves the problem of uneven watering caused by inconsistent road widths in traditional handcart maintenance methods, while reducing the inconvenience of pushing the cart back and forth, improving operational convenience and maintenance effect. Preferably, one end of the spray pipe is closed, and the other end is connected to a control pipe. The control pipe is vertically mounted on the base and passes upward through the base. A water guide pipe is provided at the upper end of the control pipe and connected to the water pump through the water guide pipe. The drive assembly can drive the control pipe to rotate.

[0009] By adopting the above technical solution, the control tube is mounted vertically on the base and passes through the base upwards, which enables the stable rotation of the water spray pipe.

[0010] Preferably, the drive assembly includes gears, a drive block, and a cylinder. The control pipe is correspondingly arranged with the two water spray pipes. The gears are respectively sleeved on the two control pipes. The drive block is slidably disposed between the two gears, and teeth are provided on both sides of the drive block. The teeth on both sides of the drive block mesh with the two gears respectively. The telescopic shaft of the cylinder is connected to the drive block. The straight line formed by the connection of the two control pipes is perpendicular to the length direction of the telescopic shaft of the cylinder.

[0011] By adopting the above technical solution, the cylinder in the drive assembly drives the drive block to slide between two gears. The teeth on both sides of the drive block mesh with the two gears respectively, thereby driving the two control pipes to rotate. Since the two control pipes are connected to the two water spray pipes respectively, the two water spray pipes can rotate synchronously. When the cylinder extension shaft extends or retracts, the direction of movement of the drive block changes, causing the two water spray pipes to rotate towards the center line of the base at an acute angle, or away from the center line of the base at a flat angle.

[0012] Preferably, the base is provided with a stop block, and when the drive block slides away from the cylinder to abut the stop block, the two water spray pipes rotate to a horizontal angle.

[0013] By adopting the above technical solution, the setting of the stop provides a precise limit for the angle adjustment of the water spray pipe.

[0014] Preferably, it also includes guide seats, two of which are provided, and the two water spray pipes are respectively connected to the two guide seats. The guide seats are provided with guide blocks, and the lower surface of the base is provided with guide grooves for the guide blocks to slide. The two ends of the guide grooves are arc-shaped grooves. When the two water spray pipes rotate, the two guide blocks slide in the guide grooves.

[0015] By adopting the above technical solution, the guide seat and guide block can accurately guide the rotation of the water spray pipe, ensuring that the water spray pipe maintains a stable motion trajectory during rotation.

[0016] Preferably, the guide block includes a first column and a second column, the first column being connected between the second column and the guide seat, and the diameter of the second column being larger than that of the first column.

[0017] By adopting the above technical solution, the sliding stability of the guide block in the guide groove can be effectively improved, and the guide block can be prevented from shifting or falling out of the guide groove during the sliding process.

[0018] Preferably, it further includes a positioning element for limiting the sliding of the drive block. The positioning element includes a clamping block, a control block, and a screw. The clamping block is disposed on one side of the drive block, and teeth are provided on the side wall of the clamping block facing the drive block. The clamping block is connected to the control block. The screw can be threaded through the control block, and the length direction of the screw is perpendicular to the length direction of the cylinder extension shaft.

[0019] By adopting the above technical solution, the positioning component can effectively limit the sliding of the drive block, thereby ensuring the stability of the water spray pipe at a specific angle. Specifically, the teeth on the clamping block mesh with the drive block, providing a reliable fixing effect and preventing changes in the angle of the water spray pipe due to external vibration or impact. The design of the screw and control block allows the operator to easily adjust and lock the angle of the water spray pipe, meeting the maintenance needs of roads of different widths and improving maintenance efficiency and accuracy.

[0020] Preferably, the positioning component further includes a limiting block, which is disposed on the lower surface of the abutment block, and the base is provided with a limiting groove for the limiting block to slide.

[0021] By adopting the above technical solution, the setting of the limiting block and the limiting groove provides the limiting block with a precise sliding trajectory, avoiding the clamping block from shifting or getting stuck during operation, and further improving the overall reliability of the device.

[0022] Preferably, the positioning element further includes a handle connected to the end of the screw away from the drive block.

[0023] By adopting the above technical solution, the handle is designed to allow operators to rotate the screw by holding the handle, thereby adjusting the positional relationship between the clamping block and the driving block.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. By setting up rotatable water spray pipes and drive components, the two water spray pipes can flexibly adjust their angles according to the actual road width. They can be brought close together at an acute angle to adapt to narrow roads, or moved away at a flat angle to cover wide roads, thus solving the problem of low efficiency of traditional fixed-width spraying devices under different road widths.

[0026] 2. Adding a guide seat can increase the stability of the water spray pipe when it rotates. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] Example 1:

[0034] This application discloses a concrete pavement curing device. (Refer to...) Figure 1 and Figure 2The maintenance device includes a base 1, a push rod 2, a water tank 3, a water pump 4, a spray pipe 5, nozzles 6, and a drive assembly 7. The base 1 mainly serves as a load-bearing structure, and casters can be installed circumferentially under the base 1 to facilitate the rotation of the maintenance device. The push rod 2 is connected to the rear end of the base 1 and is used to control the movement of the base 1. The water tank 3 is used to store maintenance water, and the water pump 4 is used to pump water from the water tank 3 to the spray pipe 5. The spray pipe 5 is equipped with several nozzles 6 for spraying water streams or water mists. The spray pipe 5 is rotatably mounted under the base 1, and the rotation of the spray pipe 5 is controlled by the drive assembly 7 to adjust the spray angle.

[0035] Two water spray pipes 5 are provided. The drive assembly 7 can drive the two water spray pipes 5 to rotate simultaneously. When the two water spray pipes 5 rotate towards the center line of the base 1, that is, when the far ends of the two water spray pipes 5 rotate closer to each other, the included angle between the two water spray pipes 5 becomes smaller and smaller. Correspondingly, the width covered by the two water spray pipes 5 becomes smaller and smaller. The end of the water spray pipe 5 closer to the center of rotation is called the proximal end, and the end farther away from the center of rotation is called the distal end. When the two water spray pipes 5 rotate away from the center line of the base 1, that is, when the far ends of the two water spray pipes 5 rotate away from each other, the included angle between the two water spray pipes 5 becomes larger and larger. Correspondingly, the width covered by the two water spray pipes 5 becomes larger and larger. Finally, the two water spray pipes 5 can rotate to form a flat angle. At this time, the width covered by the two water spray pipes 5 reaches its maximum. With this design, the spraying range of the water pipe 5 can be adjusted according to actual needs. When the angle between the two water pipes 5 is small, the amount of water received per unit area per unit time is relatively larger, and the base 1 can be moved faster during maintenance. When the angle between the two water pipes 5 is large, although the moving speed needs to be reduced accordingly to ensure sufficient watering of the ground, the water pipe 5 can effectively cover roads of different widths without the need to move the maintenance device back and forth, thus improving work efficiency and ensuring maintenance quality.

[0036] Reference Figure 1 and Figure 2 Specifically, the water spray pipe 5 can be a metal pipe or a plastic pipe. Two water spray pipes 5 are respectively set below the base 1. The far end of each water spray pipe 5 is closed, and its near end is connected to a control pipe 51. The control rod is preferably integrally bent with the water spray pipe 5. The control pipe 51 is rotatably set on the base 1 in the vertical direction. Its outer wall can be stably rotatably connected to the base 1 by bearings or other means. A water guide pipe 52 is set at the upper end of the control pipe 51. At the same time, the control pipe 51 passes upward through the base 1 and is connected to the water pump 4 through the water guide pipe 52. The water guide pipe 52 can be fixed to the base 1 by relevant fixed supports or fixed buckles. The end of the water guide pipe 52 near the control pipe 51 is bent downward and inserted into the control pipe 51. The water guide pipe 52 and the control pipe 51 are rotatably connected. A sealing structure can be added at the connection.

[0037] Reference Figure 1 and Figure 3 In this embodiment, the drive assembly 7 includes a gear 71, a drive block 72, and a cylinder 73. The gear 71 is sleeved on the outer wall of the upper end of the two control pipes 51 and is fixedly connected to the control pipes 51. The drive block 72 is slidably disposed between the two gears 71. The drive block 72 is a rectangular block with teeth on both sides, which mesh with the two gears 71 respectively. The telescopic shaft of the cylinder 73 is connected to the end of the drive block 72. When the cylinder 73 is activated, the drive block 72 slides horizontally, thereby driving the two gears 71 to rotate synchronously. Since the straight line formed by the connection of the two control pipes 51 is perpendicular to the length direction of the telescopic shaft of the cylinder 73, the action of the cylinder 73 can precisely control the rotation angle of the water spray pipe 5. At the same time, when the control pipe 51 rotates to a suitable angle, the water spray pipe 5 can be initially positioned through the cooperation of the cylinder 73, the drive block 72, and the gear 71.

[0038] Reference Figure 1 and Figure 3 In an optional embodiment, a stop block 11 is also fixed to the upper surface of the base 1 by bolts or other means. The stop block 11 is a rectangular block. When the drive block 72 slides away from the cylinder 73 and abuts against the stop block 11, the two water spray pipes 5 rotate to a horizontal angle, achieving the maximum spray angle and spray range. This provides the operator with a clear reference point. Optionally, a rectangular block can also be set at the other end of the drive block 72. When the two water spray pipes 5 rotate to the minimum included angle, that is, rotate to be parallel to each other, the other end of the drive block 72 abuts against the rectangular block.

[0039] Reference Figure 2 and Figure 3 The maintenance device also includes guide seats 8, of which two are provided, each connected to one of the two water spray pipes 5. A guide block 81 is fixedly mounted on the upper surface of the guide seat 8, and a guide groove 12 is provided on the lower surface of the base 1 for the guide block 81 to slide. The two ends of the guide groove 12 are arc-shaped grooves, and the diameter of the arc-shaped grooves corresponds to the distance between the guide seat 8 and the control shaft. When the two water spray pipes 5 rotate, the two guide blocks 81 will slide in the guide groove 12, thereby playing a guiding role and ensuring that the water spray pipes 5 rotate smoothly and accurately.

[0040] Furthermore, the guide block 81 includes a first column and a second column. The first column is connected between the second column and the guide seat 8. The diameter of the second column is larger than that of the first column, so that the cross section of the guide block 81 is "T" shaped. This design further limits the water spray pipe 5, restricts the water spray pipe 5 from swaying up and down in the vertical direction, and further improves the stability of the movement of the water spray pipe 5.

[0041] The implementation principle of the concrete pavement maintenance device in this application embodiment is as follows: Based on the required pavement width, the cylinder 73 is first activated to drive the two water spray pipes 5 to rotate to a suitable angle, ensuring that the two water spray pipes 5 can precisely cover the pavement. Then, the base 1 is moved while water is sprayed through the nozzles 6 to maintain the pavement. Compared to traditional fixed-length water spray pipes 5, this device can adapt to roads of different widths, reducing the number of back-and-forth operations and improving work efficiency.

[0042] Example 2:

[0043] The difference between this embodiment and the above embodiment is that a positioning element 9 is added to limit the sliding position of the drive block 72, thereby improving the stability of the water spray pipe 5 during operation.

[0044] Reference Figure 1 and Figure 4 Specifically, the positioning component 9 includes a clamping block 91, a control block 92, and a screw 93. The clamping block 91 is located on one side of the drive block 72, and its side wall facing the drive block 72 has teeth for meshing with the teeth on the drive block 72. The clamping block 91 and the control block 92 can be connected by welding a rectangular block. The screw 93 can be threaded through the control block 92, and the length direction of the screw 93 is perpendicular to the length direction of the telescopic shaft of the cylinder 73. A support can be fixed on the upper surface of the base 1 for rotating the screw 93. When the screw 93 is rotated, the lower surface of the clamping block 91 abuts against the upper surface of the base 1. Therefore, under the action of the screw 93, the clamping block 91 moves towards or away from the drive block 72, clamping or releasing the drive block 72.

[0045] Furthermore, the positioning component 9 also includes a limiting block 94 and a handle 95. The limiting block 94 is disposed on the lower surface of the abutment block 91, and a limiting groove 13 is provided on the base 1 for the limiting block 94 to slide. The limiting block 94 can be configured as a rectangular block, a T-shaped block, or a dovetail block, etc. The design of the limiting block 94 and the limiting groove 13 can prevent the positioning component 9 from shifting during operation. The handle 95 is connected to the end of the screw 93 away from the drive block 72, making it convenient for the operator to hold and rotate the screw 93. The surface of the handle 95 can be provided with anti-slip texture to improve operating comfort.

[0046] The implementation principle of this embodiment is as follows: by adding the positioning component 9, the water spray pipe 5 can be stably limited, preventing the water spray pipe 5 from shaking during use, and also reducing the force transmitted to the cylinder 73 when the water spray pipe 5 is subjected to external force in the direction of rotation. At the same time, the operation of the positioning component 9 is simple and convenient; locking or unlocking can be completed simply by rotating the screw 93, which improves the practicality and reliability of the device.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
