[0035] Example 1

[0036] like Figure 1-4 As shown, the present invention proposes a road and bridge construction joint cutting machine, which includes a mobile vehicle 1, a lifting assembly 3, a baffle 4, a protective assembly, and a spraying assembly;

[0037] The lifting assembly 3 is installed on the top of the mobile vehicle 1. The top of the lifting assembly 3 is equipped with a cutting assembly for construction of roads and bridges in use. One end of the cutting assembly passes through the mobile vehicle 1.

[0038] The protective shell is set on the top of the mobile vehicle 1 and the lifting assembly 3 and is fitted over one end of the cutting assembly.

[0039] The spraying assembly is located at the top of the mobile vehicle 1 and on one side of the lifting assembly 3, with one end extending to the bottom of the mobile vehicle 1 and facing downwards towards one end of the cutting assembly.

[0040] The baffle 4 is installed at the bottom of the mobile vehicle 1, and the bottom of the mobile vehicle 1 has wheels. The height of the baffle 4 is less than the height of the wheels of the mobile vehicle 1.

[0041] In this embodiment, the cutting component is moved to the location on the road or bridge to be cut by the mobile vehicle 1. The cutting component is then activated, and the lifting component 3 slowly lowers the cutting component to bring it into contact with the road and perform the cutting operation. Simultaneously, the spraying component sprays water onto the cutting location to reduce dust and cool the cutting component. A baffle 4 is placed below the mobile vehicle 1 to block debris generated during the cutting process. As the cutting component moves, the top of the protective component moves synchronously with it to prevent breakage and splashing during use. The lowering distance of the cutting component is controlled by the lifting component 3 to control the cutting depth. At the same time, the mobile vehicle 1 is pushed to move along the width of the road or bridge, allowing the cutting component to perform the cutting operation along the width of the road or bridge.

[0042] Example 2

[0043] like Figure 1 and Figure 3 As shown, the road and bridge construction joint cutting machine proposed in this utility model differs from the first embodiment in that the lifting component 3 includes a mounting plate 31, a support frame 33, and a telescopic rod 34.

[0044] Mounting plate 31 is positioned above the mobile vehicle 1;

[0045] There are two support frames 33, which are arranged in an X shape and rotate relative to each other between the mounting plate 31 and the mobile vehicle 1. Each of the two support frames 33 has a roller at one end, which is rotatably connected to the mounting plate 31 and the mobile vehicle 1 respectively. The other end of the two support frames 33 has a rotating seat, which is fixedly connected to the mounting plate 31 and the mobile vehicle 1 respectively.

[0046] The telescopic rod 34 is located at one end inside a support frame 33 and connected to the middle of another support frame 33. The telescopic rod 34 can be an electric telescopic rod, a pneumatic telescopic rod, or a hydraulic cylinder.

[0047] In an optional embodiment, a limit block 32 is provided at the top of the mobile vehicle 1 and the bottom of the mounting plate 31, and one end of the support frame 33 is located inside the limit block 32, which is used to limit the roller at the end of the support frame 33 during use.

[0048] In this embodiment, two support frames 33 are arranged in an X shape and extended and retracted by a telescopic rod 34. The rollers at the ends of the two support frames 33 slide at the bottom end of the mounting plate 31 and the top end of the moving vehicle 1 under the action of the rotating seat at the other end, so that the distance between the mounting plate 31 and the moving vehicle 1 can be adjusted. During operation, the mounting plate 31 drives the cutting component to adjust its position, so that the cutting component can cut gaps of different depths.

[0049] Example 3

[0050] like Figure 1-2 and Figure 4 As shown, the road and bridge construction joint cutting machine proposed in this utility model differs from the first embodiment in that the cutting component includes a driver 2 and a cutting blade 11.

[0051] The driver 2 is mounted on the top of the mounting plate 31, wherein the driver 2 is one of an electric motor, a diesel engine, and a gasoline engine;

[0052] The cutting disc 11 is installed at one end of the driver 2.

[0053] In an optional embodiment, a through hole 12 is provided at the top of the mobile vehicle 1 and below the cutting blade 11, the width and length of the through hole 12 being greater than the thickness and diameter of the cutting blade 11, respectively.

[0054] In this embodiment, the driver 2 drives the cutting blade 11 to rotate, so that the cutting blade 11 cuts the road surface when it comes into contact with the road surface. The through hole 12 is larger than the size of the cutting blade 11, so that there is no obstruction between the moving vehicle 1 and the cutting blade 11.

[0055] Example 4

[0056] like Figure 1 and Figure 4 As shown, the present invention proposes a road and bridge construction joint cutting machine. Compared with the first embodiment, the difference in this embodiment is that the protective components include a first protective shell 5 and a second protective shell 6.

[0057] The second protective shell 6 is bolted to the top of the mounting plate 31 and sleeved on the outside of the cutting blade 11;

[0058] The first protective shell 5 is bolted to the top of the mobile vehicle 1 and fitted onto the outside of the second protective shell 6.

[0059] In this embodiment, while the driver 2 and the cutting blade 11 are moved by the mounting plate 31, the second protective shell 6 is sleeved on the outer side of the top of the cutting blade 11 and moves with the cutting blade 11, so that the second protective shell 6 protects the cutting blade 11. At the same time, the second protective shell 6 is located inside the first protective shell 5, so that the second protective shell 6 moves inside the first protective shell 5 and the first protective shell 5 provides secondary protection for the cutting blade 11, ensuring construction safety and avoiding safety accidents caused by the cutting blade 11 breaking, splashing, or falling off during the cutting process. In addition, since both the first protective shell 5 and the second protective shell 6 are bolted, the replacement of the cutting blade 11 is more convenient.

[0060] Example 5

[0061] like Figure 1-2 As shown, the present invention proposes a road and bridge construction joint cutting machine. Compared with the first embodiment, the difference in this embodiment is that the spraying assembly includes a water tank 7, a water pump 8, a water pipe 9, and a nozzle 10.

[0062] Water tank 7 is installed on top of mobile vehicle 1;

[0063] Water pump 8 is located at the top of water tank 7;

[0064] Water pipe 9 is installed at one end of water pump 8, and the other end extends to the bottom of mobile vehicle 1;

[0065] There are multiple nozzles 10, all of which are installed at one end of the water pipe 9 and arranged facing downwards towards the cutting blade 11.

[0066] In this embodiment, water is pumped from water tank 7 by water pump 8 and transported to nozzle 10 through water pipe 9, so that nozzle 10 sprays water onto the cutting position and forms a uniform spray, which reduces the cutting temperature of cutting blade 11, reduces the generation of cutting dust, improves cutting efficiency, and ensures a clean construction environment.

[0067] In this invention, the mobile vehicle 1 is moved to the location on the road or bridge to be cut, and the driver 2 is activated. The driver 2 drives the cutting blade 11 to rotate rapidly. The extension of the telescopic rod 34 causes the rollers at the ends of the two support frames 33 to slide between the bottom of the mounting plate 31 and the top of the mobile vehicle 1, through the action of the rotating seat at the other end. This reduces the distance between the mounting plate 31 and the mobile vehicle 1, causing the mounting plate 31 to move the driver 2 downwards. The cutting blade 11 then passes through the through hole 12 and contacts the road surface to perform the cutting operation. The cutting depth of the cutting blade 11 is adjusted by the extension length of the telescopic rod 34 to ensure the cutting depth is achieved. The cutting process is precise and deep. Simultaneously, the water pump 8 draws water from the water tank 7 and delivers it to the nozzle 10 through the water pipe 9. The nozzle 10 sprays water onto the cutting position, forming a uniform spray. This reduces the cutting temperature of the cutting blade 11, minimizes the generation of cutting dust, and effectively prevents debris from splashing during the cutting process by blocking the baffle 4. The second protective shell 6 moves with the cutting blade 11 within the first protective shell 5, protecting the cutting blade 11 and ensuring operational safety. At the same time, it pushes the moving vehicle 1 along the width of the road and bridge, allowing the cutting assembly to perform cutting work along the width of the road and bridge.

[0068] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
