Detailed Implementation

[0051] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0052] Example:

[0053] like Figures 1-10 As shown, the grooving machine for highway inspection and maintenance provided in this embodiment includes a base frame 100, a cutting assembly 200, and a drive assembly, wherein:

[0054] The base frame 100 is equipped with casters 110 with built-in brakes; of course, these casters 110 can also be ordinary rollers. The base frame 100 is also connected to a handle 120 to facilitate the operator's movement of the cutting machine. Preferably, the handle 120 is fitted with a non-slip sleeve made of silicone or foam. Using the handle 120 and the casters 110, the operator can move the grooving machine to the desired position, and when moved to a designated position, the brakes on the casters 110 can secure the grooving machine in that position.

[0055] The cutting direction of the cutting component 200 is defined as the first direction. The cutting component 200 is slidably mounted on the base frame 100 along a second direction, which is perpendicular to the first direction in the horizontal plane. Furthermore, there are two sets of the cutting components 200, which are distributed sequentially along the second direction.

[0056] The aforementioned drive assembly is mounted on the base frame 100 and connected to the aforementioned cutting assembly 200. This drive assembly is used to drive the cutting assembly 200 to slide in the second direction, thereby changing the spacing between the two sets of cutting assemblies 200. It is readily understood that the drive assembly can also lock the cutting assembly 200 onto the base frame 100 so that it does not move in the second direction when cutting the road.

[0057] With the above structure, the grooving machine provided in this embodiment, using two sets of cutting components 200, can simultaneously cut two slits extending in a first direction on a road. In specific use, the grooving machine is first moved to a designated position so that the cutting components 200 correspond to the part of the road that needs to be grooved. Then, the required width of the groove is determined. Next, the driving component is used to drive the cutting components 200 to slide in a second direction so that the distance between the two cutting components 200 corresponds to the required width of the groove. Then, the two cutting components 200 are started simultaneously, and the two cutting components 200 cut the road surface at the same time, thereby creating two slits on the road surface. The distance between the two slits is the required width of the groove. Thus, compared with the existing grooving machines that can only cut one groove on the road at a time, the grooving machine provided in this embodiment can cut two grooves at a time. In addition, the distance between the two cutting components 200 can be adjusted according to the width of the required groove, so it is suitable for opening grooves of different widths on the road, saving grooving construction time and making it more practical.

[0058] Optionally, a protective cover 500 is also installed on the base frame 100. This protective cover 500 covers the cutting assembly 200 and the driving assembly, thereby protecting them and reducing dust emitted during cutting. The handle 120 is located behind the protective cover 500, and an opening is formed through the front side wall of the protective cover 500, allowing workers to easily view the interior of the protective cover 500, i.e., the cutting progress of the cutting assembly 200. For even better viewing, the protective cover 500 can be made of transparent material, allowing workers to view the interior from all sides.

[0059] The aforementioned protective cover 500 is fixed to the aforementioned base frame 100 by bolts for easy assembly and disassembly.

[0060] More preferably, a dust suppression component 600 is also installed on the aforementioned protective cover 500. This dust suppression component 600 is used to reduce the dust generated when the cutting component 200 cuts the road. This further reduces the dust that flies outward during cutting. Optionally, the aforementioned dust suppression component 600 includes a water tank 610, a water pump 620, and a nozzle 650, wherein:

[0061] The water tank 610 is installed on the top wall of the protective cover 500 and located outside the protective cover 500. The water tank 610 is provided with a water inlet, and a plug is inserted into the water inlet. When water needs to be added to the water tank 610, the plug is removed, and when the water is added, the plug is inserted into the water inlet. A viewing window is opened on one side wall of the water tank 610, and a transparent sealing plate is installed in the viewing window. Through the transparent sealing plate, the operator can check the water level in the water tank 610.

[0062] The aforementioned water pump 620 is installed on the top surface of the water tank 610. The water pump 620 has an inlet end and an outlet end. The inlet end is connected to the water tank 610 via an inlet pipe 630, and the outlet end is connected to an outlet pipe 640. When the water pump 620 is powered on, it draws water from the water tank 610 through the inlet pipe 630 to the outlet pipe 640. Spray nozzles 650 are installed on the side wall of the protective cover 500. Specifically, multiple spray nozzles are installed on one side wall of the protective cover 500, and all spray nozzles 650 are connected to the outlet pipe 640. Thus, the water pump 620 can draw water to the spray nozzles 650 for spraying. The spray nozzles 650 face the cutting position of the cutting assembly 200. When the cutting assembly 200 is cutting, the spray nozzles 650 spray water towards the cutting position, thereby reducing the amount of dust flying out from the cutting position and achieving a dust suppression effect. It should be noted that there are two water pumps 620, and several nozzles 650 are installed on both opposite side walls of the protective cover 500. Thus, the two water pumps 620 can pump water to the nozzles 650 on both opposite side walls of the protective cover 500, with the nozzles 650 facing the cutting positions of the two sets of cutting components 200 respectively. In addition, a pipe clamp is provided on the outer wall of the protective cover 500 to secure the water outlet pipe 640 to the outer wall of the protective cover 500. Of course, this embodiment also implicitly includes a power supply for powering the water pumps 620 and the cutting components 200.

[0063] Of course, the dust suppression component 600 mentioned above can also include a vacuum cleaner installed on the protective cover 500. When the cutting component 200 is cutting, the vacuum cleaner is activated to suck away the dust generated during cutting.

[0064] An optional implementation of this embodiment is as follows: The cutting assembly 200 includes a base plate 210, a motor 230, a saw blade 240, and a belt drive pair 260, wherein:

[0065] The base plate 210 is slidably connected to the base frame 100, thereby allowing the entire cutting assembly 200 to be slidably mounted on the base frame 100. One end of the base plate 210 is hinged to a mounting plate 220 via a hinge shaft. The mounting plate 220 is located above the base plate 210 and can rotate about the hinge point on the base plate 210. The axial direction of the hinge shaft is the second direction mentioned above, ensuring that the rotation of the mounting plate 220 is in the horizontal plane. The mounting plate 220 is connected to a pressing mechanism 300, which drives the mounting plate 220 to rotate in the vertical plane.

[0066] The motor 230 is bolted to the mounting plate 220 and is electrically connected to the power source. The saw blade 240 is rotatably mounted on the mounting plate 220 via a shaft 250. Specifically, a support is provided on the mounting plate 220, the shaft 250 is rotatably inserted into the support, and the saw blade 240 passes through one end of the shaft 250. A nut is screwed to one end of the shaft 250, pressing the saw blade 240 firmly onto the shaft 250. The saw blade 240 is located to the side of the mounting plate 220, and the axial direction of the shaft 250 is a second direction. The base plate 210 has clearance holes for the saw blade 240 to pass through. A belt drive pair 260 connects the output shaft of the motor 230 and the shaft 250, transmitting the power output from the motor 230 to the shaft 250.

[0067] When cutting is not required, the pressing mechanism 300 drives the mounting plate 220 to its highest point, at which point the saw blade 240 is positioned above the base plate 210. During cutting, the motor 230 is first started, causing the saw blade 240 to rotate. Then, the pressing mechanism 300 drives the mounting plate 220 to rotate downwards, causing the saw blade 240 to move downwards. After passing through the clearance hole, the saw blade 240 contacts the road surface, thus cutting the road surface. Initially, the caster wheel 110 is braked to prevent the grooving machine from moving in the first direction. After cutting to the specified depth, the brake is released, and the operator pushes the grooving machine in the first direction. After cutting, the motor 230 is turned off, and the pressing mechanism 300 drives the mounting plate 220 to rotate upwards, causing the saw blade 240 to return to its position above the base plate 210.

[0068] Of course, the aforementioned mounting plate 220 can also be mounted on the base plate 210 via a lifting mechanism. That is, the mounting plate 220 is not mounted on the base plate 210 in a rotating manner, but rather mounted on the base plate 210 in a vertically lifting manner.

[0069] An optional implementation of this embodiment is as follows: The pressing mechanism 300 includes a side plate 310, a connecting rod 330, a pressing rod 340, and a locking part, wherein:

[0070] The side plate 310 is integrally formed or welded to the outer wall of the mounting plate 220, and the side plate 310 is provided with a protruding rod 320 extending in the second direction. The connecting rod 330 extends in the vertical direction, and the bottom end of the connecting rod 330 is integrally formed or welded to the protruding rod 320. Alternatively, a circular hole can be opened at the bottom of the connecting rod 330, and the protruding rod 320 can be rotatably inserted into the circular hole. A through hole 331 is opened at the top of the connecting rod 330, and the axial direction of the through hole 331 is the second direction.

[0071] A long through groove 510 is formed on one side wall of the protective cover 500, with the length of the groove 510 being vertical. A pressing rod 340 is slidably inserted into the through hole 331 and the long through groove 510. In practice, the outer diameter of the pressing rod 340 is smaller than the width of the long through groove 510. If the long through groove 510 is an arc-shaped groove, then the outer diameter of the pressing rod 340 can be adapted to the width of the long through groove 510. Furthermore, one end of the pressing rod 340 is provided with a handle 341 located outside the protective cover 500. Specifically, the other end of the pressing rod 340 first passes through the long through groove 510, then through the through hole 331 on the connecting rod 330 of one of the cutting components 200, and finally through the through hole 331 on the connecting rod 330 of the other cutting component 200. In this way, the pressure bar 340 can move up and down in the long through slot 510. In actual use, the operator can hold the handle 341 from the side to drive the pressure bar 340 up and down, or directly grasp the pressure bar 340 from the front through the opening of the protective cover 500 to drive the pressure bar 340 up and down. When the pressure bar 340 is simultaneously inserted into the through hole 331 on the connecting rod 330 of the two cutting components 200, the pressure bar 340 can drive the mounting plate 220 of the two cutting components 200 to rise and fall synchronously, thereby achieving the effect of the saw blades 240 of the two cutting components 200 cutting the road surface at the same time.

[0072] A locking part is detachably installed between the pressure rod 340 and the protective cover 500. The locking part is used to lock the pressure rod 340 to the protective cover 500. With the help of this locking part, when cutting is not required, the pressure rod 340 is at its highest point, and at this time, the pressure rod 340 is locked to the protective cover 500 by the locking part; when cutting, the locking part is unlocked, and when the saw blade 240 cuts to the specified depth, the locking part is locked again to maintain the specified depth of cutting when pushing the grooving machine to move in the first direction.

[0073] Of course, the aforementioned pressing mechanism 300 can also be an electric telescopic assembly installed inside the protective cover 500, such as an electric telescopic rod. This electric telescopic assembly has a telescopic shaft, and the telescopic direction of the telescopic shaft is up and down. The free end of the telescopic shaft abuts against the mounting plate 220. In this way, when the telescopic shaft extends, it can drive the mounting plate 220 to rotate downward. In this case, a return spring needs to be set between the mounting plate 220 and the base plate 210. When not cutting, the return spring pushes the mounting plate 220 upward. When cutting, the telescopic shaft extends, causing the mounting plate 220 to move downward and compress the return spring. After cutting, the telescopic shaft retracts, and the compressed return spring drives the mounting plate 220 to move upward again to the highest point.

[0074] An optional implementation of this embodiment is as follows: the locking part includes a first bolt 360 and a protruding plate 350, wherein:

[0075] A protruding plate 350 protrudes from the axial side wall of the lower pressure rod 340. The protruding plate 350 is located outside the protective cover 500 and has a through hole 351. Several screw holes 520 are provided on the side wall of the protective cover 500. The positions of the screw holes 520 correspond to the through holes 351. The screw holes 520 are arranged sequentially along an arc in the vertical direction. The first bolt 360 passes through the through hole 351 and is screwed into one of the screw holes 520.

[0076] When the first bolt 360 is screwed into one of the screw holes 520, the lowering rod 340 is locked onto the side wall of the protective cover 500. When the first bolt 360 is unscrewed, the lowering rod 340 is released, allowing it to move up and down. Furthermore, the degree of vertical movement of the lowering rod 340 varies depending on which screw hole 520 the first bolt 360 is screwed into. It should be noted that this type of locking mechanism can lock the lowering rod 340 onto the side wall of the protective cover 500 or release it; its adjustment method is not stepless.

[0077] Of course, the handle 341 at one end of the aforementioned pressure rod 340 can also be removed and replaced with a pressure cap. The pressure cap is screwed to one end of the pressure rod 340. When locked, the pressure cap presses against the outer wall of the protective cover 500, thus enabling stepless adjustment.

[0078] An optional implementation of this embodiment is as follows: The driving component in this embodiment includes two driving units 400, which are respectively connected to two sets of cutting components 200, thereby using the two driving units 400 to drive the two sets of cutting components 200 to slide along the second direction. In this way, the two cutting components 200 can be driven to move independently.

[0079] Of course, the aforementioned driving component can also be connected to both cutting components 200, thereby using the driving component to drive the two cutting components 200 to move synchronously.

[0080] This embodiment illustrates the example of two cutting components 200 moving independently, each driven by a different drive unit 400. Optionally, the drive unit 400 includes a lead screw 410, a slider 420, and a second bolt 430, wherein:

[0081] The lead screw 410 extends along the second direction. A middle beam 130 extending along the first direction is provided in the middle of the base frame 100. Two slide grooves 140 extending along the second direction are opened between the middle beam 130 and the end of the base frame 100. A lead screw 410 is rotatably installed in each slide groove 140. One end of the lead screw 410 passes through the end of the base frame 100 and extends outside the base frame 100. The other end of the lead screw 410 is rotatably inserted into the middle beam. A handle 411 located outside the base frame 100 is also installed at one end of the lead screw 410. With the help of the handle 411, the user can easily rotate the lead screw 410. Each slide groove 140 has a slider 420 slidably mounted thereon, and each slider 420 has a threaded through hole. A lead screw 410 is screwed into the threaded through hole, forming a lead screw 410-nut drive pair with the slider 420. The base plate 210 of the cutting assembly 200 is connected to the slider 420. Specifically, a stud is provided on the top surface of the slider 420, and the base plate 210 has a through hole. The stud passes through the through hole and is screwed into a nut, thereby pressing the base plate 210 against the top surface of the slider 420 with the nut. Of course, the base plate 210 is connected to the sliders 420 in both slide grooves 140 simultaneously, so that the base plate 210 spans the base frame 100.

[0082] Thus, when it is necessary to adjust the distance between the two cutting components 200, rotating both lead screws 410 simultaneously will cause one cutting component 200 to translate along the second direction. A second bolt 430 is screwed onto the intermediate beam 130. The second bolt 430 is used to press the other end of the lead screw 410 against the intermediate beam 130. When the second bolt 430 is tightened, it presses the lead screw 410 against the intermediate beam 130, preventing it from rotating. When the second bolt 430 is loosened, the lead screw 410 can rotate. Thus, when it is not necessary to adjust the distance between the two cutting components 200, the second bolt 430 is tightened.

[0083] like Figure 4 , Figure 6 as well as Figure 8As shown, in this embodiment, the two cutting components 200 are respectively installed on both sides of the intermediate beam 130. In fact, the base frame 100 has four sliding grooves 140, two of which are located on one side of the intermediate beam 130, where the sliders 420 in these two grooves are used to install one cutting component 200. The other two are located on the other side of the intermediate beam 130, where the sliders 420 in these two grooves are used to install the other cutting component 200. A lead screw 410 is rotatably installed in each groove 140. There are two second bolts 430, which are used to lock the lead screws 410 on both sides of the intermediate beam 130.

[0084] Of course, the aforementioned lead screw and nut drive pair can also be replaced by an electric telescopic rod. This electric telescopic rod is installed on the side wall of the protective cover 500, and the telescopic direction of the electric telescopic rod is the second direction. The free end of the telescopic shaft of the electric telescopic rod is connected to the aforementioned base plate 210. In this case, a slide rail can be provided on the aforementioned base frame 100, and a slide bar can be provided on the bottom surface of the base plate 210, with the slide bar slidably installed in the slide rail.
