Description

Technical Field

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

[0002] In road and bridge maintenance, grinding machines (milling machines) are indispensable core equipment. They are mainly used to efficiently remove asphalt pavement defects (such as ruts, cracks, bumps, etc.) through rotary milling technology. The operation process uses a hydraulic system to precisely control the milling depth (adjustable from 0-30cm) and flatness. It is equipped with an automatic leveling system to ensure that the base surface error is ≤3mm. At the same time, it integrates a waste recycling device to achieve 100% recycling of old materials.

[0003] After the road surface grinding is completed, the construction workers need to collect the generated dust for waste recycling. Since this step cannot be performed simultaneously with the grinding process, this secondary operation mode objectively increases the labor intensity of the workers.

[0004] Therefore, it is urgent to improve road and bridge maintenance equipment to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a road and bridge maintenance device that can not only absorb and collect dust, but also flush out impurities in the collection box for easy cleaning later.

[0006] To achieve the above objectives, the main technical solution adopted by this utility model includes: a road and bridge maintenance equipment, including a support frame, with water tanks provided on both sides of the upper end face of the support frame, and a grinding mechanism connected to the water tanks provided on the support frame;

[0007] The support frame is connected to a collection box at one end away from the water tank. A push-pull handle is slidably connected to the outside of the collection box. A vacuum motor is connected to the lower end of the collection box. A support plate is connected to the lower end of the collection box and is penetrated by the suction end of the vacuum motor. Scrapers are provided on both sides of the support plate.

[0008] A water pump is installed on the upper surface of the support frame. One end of the water pump is connected to the two water tanks, and the other end of the water pump extends through to the top of the collection tank and is connected to a spraying mechanism. Discharge pipes are installed on both sides of the lower surface of the collection tank.

[0009] Preferably, the polishing mechanism includes a drive motor fixedly connected to the support frame and a polishing stone connected to the output end of the drive motor. A protective shell is fixedly connected to the lower end face of the support frame. The output end of the drive motor passes through the protective shell and is connected to the polishing stone. A water pipe is provided on the lower end face of the water tank, passing through the protective shell.

[0010] Preferably, the spraying mechanism includes a main pipe disposed above the inside of the collection box and a plurality of high-pressure spray heads distributed on the lower end face of the main pipe.

[0011] Preferably, one end of the water pump is connected to the top of the two water tanks via a diversion pipe, and the other end of the water pump is connected to the main pipeline via a water delivery pipe.

[0012] Preferably, the outer sides of the water tank and the collection tank are both transparent glass structures, the upper end of the water tank is provided with a water inlet pipe, and valves are provided on both the water pipe and the discharge pipe.

[0013] Preferably, the protective shell is a transparent protective shell, and a discharge port is provided at one end of the protective shell near the support plate.

[0014] Preferably, a fixing block is provided on the side of the collection box away from the water tank, a sliding groove is provided in the fixing block, a movable wheel is provided on the lower end face of the push-pull handle, a slider is provided on the inner side of the push-pull handle and slidably connected to the sliding groove, a screw is rotatably connected in the sliding groove and threadedly connected to the slider, and the upper end of the screw extends through to the top of the fixing block and is connected to a rotating handwheel.

[0015] This utility model has at least the following beneficial effects:

[0016] 1. During polishing, water from the tank flows through pipes to the surface of the polishing stone and the ground, trapping dust within the protective casing. The mixture then flows between two scrapers, where it is blocked by a support plate. The vacuum motor draws the wastewater mixture into a collection tank for collection, preventing dust from scattering. Later, when the collection tank needs rinsing and cleaning, a water pump draws water from the tank into a delivery pipe, which is then sprayed through the main pipe and high-pressure spray nozzles to clean the inner walls of the collection tank. The cleaned water is discharged through a drain pipe. This process not only absorbs and collects dust but also flushes away impurities from the collection tank, facilitating later cleaning.

[0017] 2. When the height of the push-pull handle needs to be adjusted according to usage requirements, the screw is rotated within the slider, thereby allowing the slider to drive the push-pull handle to adjust its height. Attached Figure Description

[0025] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0026] Examples, such as Figures 1-5 As shown, a road and bridge maintenance device includes a support frame 1, with water tanks 2 on both sides of the upper surface of the support frame 1, and a grinding mechanism 101 connected to the water tanks 2 on the support frame 1; a collection box 7 is connected to the end of the support frame 1 away from the water tanks 2, a push-pull handle 8 is slidably connected to the outside of the collection box 7, a vacuum motor 9 is connected to the lower surface of the collection box 7, and a support plate 10 is connected to the lower surface of the collection box 7 through which the suction end of the vacuum motor 9 passes, and scrapers 11 are provided on both sides of the support plate 10;

[0027] Furthermore, the polishing mechanism 101 includes a drive motor 3 fixedly connected to the support frame 1 and a polishing stone 5 connected to the output end of the drive motor 3. A protective shell 4 is fixedly connected to the lower end face of the support frame 1. The output end of the drive motor 3 passes through the protective shell 4 and is connected to the polishing stone 5. A water pipe 6 is provided on the lower end face of the water tank 2, which passes through the protective shell 4. During polishing, the water source in the water tank 2 flows to the surface of the polishing stone 5 and the ground through the water pipe 6, thereby pressing the dust into the protective shell 4. Finally, the mixture will flow between the two scrapers 11 and be blocked by the support plate 10. The sewage mixture is pumped into the collection box 7 for collection by the vacuum motor 9 to prevent the dust from scattering.

[0028] Furthermore, the protective shell 4 is a transparent protective shell, which makes it easy to observe the polishing of the polishing stone 5 inside. The protective shell 4 has a discharge port 21 at one end near the support plate 10. The dust and sewage mixture generated by the polishing stone will be blocked and collected by the protective shell 4, but will be discharged through the discharge port 21 into the space between the two scrapers 11, so that the sewage and impurities can be drawn into the collection box 7 for collection later by the vacuum motor 9.

[0029] Furthermore, a fixing block 22 is provided on the side of the collection box 7 away from the water tank 2. A groove 23 is provided in the fixing block 22. A movable wheel 24 is provided on the lower end face of the push-pull handle 8. A slider 25 is provided on the inner side of the push-pull handle 8 and is slidably connected to the groove 23. A screw 26 is rotatably connected in the groove 23 and threadedly connected to the slider 25. The upper end of the screw 26 extends through the fixing block 22 and is connected to a rotating handwheel 27. When the height of the push-pull handle 8 needs to be adjusted according to the usage requirements, the screw 26 is rotated in the slider 25 by rotating the screw 26, thereby realizing the height adjustment of the push-pull handle 8 driven by the slider 25. The rotating handwheel 27 facilitates the rotation of the screw 26, and the movable wheel 24 realizes the movement of the push-pull handle 8.

[0030] A water pump 12 is installed on the upper surface of the support frame 1. One end of the water pump 12 is connected to two water tanks 2, and the other end of the water pump 12 extends through to the top of the collection tank 7 and is connected to a spray mechanism 13. Discharge pipes 14 are installed on both sides of the lower surface of the collection tank 7. The spray mechanism 13 includes a main pipe 15 located inside and above the collection tank 7, and several high-pressure spray heads 16 distributed on the lower surface of the main pipe 15. One end of the water pump 12 is connected to the top of the two water tanks 2 via a diversion pipe 17, and the other end of the water pump 12 is connected to the main pipe 15 via a water supply pipe 18. When the collection tank 7 needs to be flushed and cleaned later, the water source in the water tank 2 is pumped into the water supply pipe 18 by the water pump 12 and the diversion pipe 17, and then sprayed out through the main pipe 15 and the high-pressure spray heads 16, thereby cleaning the inner wall of the collection tank 7. The cleaned water is discharged through the discharge pipe 14.

[0031] Furthermore, the outer sides of both the water tank 2 and the collection tank 7 are made of transparent glass, which makes it easy to observe the liquid level inside the water tank 2 and the collection tank 7. A water inlet pipe 19 is provided on the upper surface of the water tank 2 to facilitate the filling of water into the water tank 2. Valves 20 are provided on both the water pipe 6 and the discharge pipe 14, which can be used to open and close the water pipe 6 and the discharge pipe 14.

[0032] In this embodiment, as Figures 1-5 As shown in the figure, the working principle of the road and bridge maintenance equipment provided in this embodiment is as follows:

[0033] During polishing, water from water tank 2 flows through water pipe 6 to the surface of polishing stone 5 and the ground, thereby pressing the dust into the protective shell 4. Finally, the mixture flows between the two scrapers 11 and is blocked by the support plate 10. The vacuum motor 9 is used to pump the wastewater mixture into the collection box 7 for collection, preventing the dust from scattering. The dust and wastewater mixture generated on polishing stone 5 is blocked and collected by the protective shell 4, but is discharged through the discharge port 21 into the space between the two scrapers 11, making it convenient for the vacuum motor 9 to pump the wastewater and impurities into the collection box 7 for collection later.
