[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0026] As Figures 1 to 4 shown, an adjustable grooving device for highway maintenance proposed in this embodiment includes a U-shaped support plate 1. Two universal wheels are installed on both sides of the bottom of the U-shaped support plate 1. A U-shaped handle is fixedly connected to the right side of the U-shaped support plate 1. A multi-stage electric telescopic rod 6 and a PLC controller 7 electrically connected thereto are fixedly installed on the inner wall of the top of the U-shaped support plate 1. The extending end of the multi-stage electric telescopic rod 6 is fixedly connected to a lifting plate 5, and the multi-stage electric telescopic rod 6 is used to drive the lifting plate 5 to move up and down;

[0027] A shielding box 3 with a top plugging structure is movably sleeved on a lifting plate 5. Four vertical guide rods 2 are fixedly connected in a rectangular shape on the inner wall of the top of the U-shaped support plate 1. The shielding box 3 is slidably sleeved on the four vertical guide rods 2. Two vertical guide grooves are formed on both sides of the top of the shielding box 3, and the inner wall of the vertical guide groove is slidably sleeved on the outer side of the corresponding vertical guide rod 2, achieving the effect of guiding the vertical sliding of the shielding box 3. A rectangular through hole 18 is formed on the inner wall of the top of the shielding box 3. The multi-stage electric telescopic rod 6 is located in the rectangular through hole 18 and does not contact the inner wall of the rectangular through hole 18. Two balls 4 are movably embedded on both sides of the bottom of the shielding box 3. A road slotting assembly is fixedly installed at the bottom of the lifting plate 5. The road slotting assembly is used to move downward integrally when the lifting plate 5 moves downward. By moving the lifting plate 5 downward, the shielding of the shielding box 3 is removed, and its own weight makes it move downward close to the road surface to surround and dust-proof the slotting position. When the balls 4 at the bottom of the shielding box 3 move down to contact the ground, they no longer move down, so that the continuously moving-down road slotting assembly can move downward to cut and slot the road surface;

[0028] A ranging assembly electrically connected to the PLC controller 7 is installed between the right inner wall of the rectangular through hole 18 and the top of the lifting plate 5. The ranging assembly is used to measure the cutting depth distance and transmit the distance value to the PLC controller 7 when the shielding box 3 is blocked by the road surface and the lifting plate 5 continues to move downward. When the preset value is reached, the PLC controller 7 is used to control the multi-stage electric telescopic rod 6 to automatically close, achieving the effect of automatically adjusting and controlling the cutting depth; Elastic vertical guide assemblies are fixedly connected to both sides of the top of the lifting plate 5. The shielding box 3 is sleeved on the two elastic vertical guide assemblies. The elastic vertical guide assemblies are used to elastically tighten the shielding box 3 downward when the shielding box 3 is blocked by the road surface and the lifting plate 5 continues to move downward; A spraying and dust-removing and temperature-reducing assembly electrically connected to the PLC controller 7 is installed on the lifting plate 5. The elastic vertical guide assemblies are used for spraying and dust-removing during the slotting work and spraying and cooling the road slotting assembly.

[0029] Specifically, the road slotting assembly includes a fixed plate 8 fixedly installed at the bottom of the lifting plate 5. A driving motor 9 is fixedly installed on the front side of the fixed plate 8. The rear end of the output shaft of the driving motor 9 extends to the rear of the fixed plate 8 and is fixedly installed with a cutting disc 10. The bottom of the cutting disc 10 and the bottom of the ball 4 are on the same horizontal plane; The set fixed plate 8, driving motor 9 and cutting disc 10 cooperate. The driving motor 9 is used to drive the cutting disc 10 to rotate. The downward-moving lifting plate 5 drives the cutting disc 10 to move downward through the fixed plate 8 and the driving motor 9 in sequence. When the shielding box 3 is blocked by the road surface, the continuously moving-down cutting disc 10 moves downward to cut and slot the road surface.

[0030] Furthermore, the distance measuring component includes a laser distance sensor 13 fixedly installed on the right inner wall of the rectangular through hole 18. The bottom of the laser distance sensor 13 is in movable contact with a reflector 14 embedded and fixed on the top of the lifting plate 5. The laser distance sensor 13 is electrically connected to the PLC controller 7. The provided laser distance sensor 13 and reflector 14 cooperate. After the shielding box 3 is blocked and restricted by the road surface, the downward movement of the laser distance sensor 13 will be restricted. The continuously downward moving lifting plate 5 drives the reflector 14 to move downward. The laser distance sensor 13 continuously detects the distance between it and the reflector 14 and transmits the distance value to the PLC controller 7. This distance value is the mining depth distance for the cutting disc 10 to move downward for cutting. When the preset distance value is reached, the PLC controller 7 controls the multi-stage electric telescopic rod 6 to automatically close, achieving the effect of automatically adjusting and controlling the grooving depth.

[0031] Furthermore, the elastic vertical guiding component includes a T-shaped guiding rod 11 fixedly connected to the top of the lifting plate 5. The shielding box 3 is slidably sleeved on the two T-shaped guiding rods 11. Among them, two guiding holes are opened on the top inner wall of the shielding box 3, which are respectively slidably sleeved on the outer sides of the corresponding T-shaped guiding rods 11, achieving the effect of vertically sliding and guiding the T-shaped guiding rods 11. A spring 12 is fixedly connected between the top inner wall of the T-shaped guiding rod 11 and the top of the shielding box 3. The spring 12 is movably sleeved on the corresponding T-shaped guiding rod 11. The provided T-shaped guiding rod 11 and spring 12 cooperate. After the shielding box 3 is blocked and restricted by the road surface, the continuously downward moving lifting plate 5 will drive the two T-shaped guiding rods 11 to compress the two springs 12. The elastic force of the two springs 12 is used to elastically tighten the shielding box 3 downward to ensure its stable approach to the road surface to surround and dust-proof the grooving position.

[0032] Furthermore, the spraying and dust-removing and temperature-reducing component includes a water tank 15 fixedly installed on the top of the lifting plate 5 and located inside the rectangular through hole 18. Among them, a water inlet pipe for adding water is connected and fixed to the top of the water tank 15. An avoidance hole is opened on the left side of the bottom of the lifting plate 5. A water pump 16 is fixedly installed at the bottom of the water tank 15 and located inside the avoidance hole. The water inlet of the water pump 16 extends into the water tank 15. The water outlet of the water pump 16 is connected and fixed to a spray nozzle 17 located above the cutting disc 10. A storage battery is fixedly installed on the left inner wall of the U-shaped support plate 1. The water pump 16, the drive motor 9, the PLC controller 7, and the multi-stage electric telescopic rod 6 are all electrically connected to the storage battery, achieving the effect of supplying power to the water pump 16, the drive motor 9, the PLC controller 7, and the multi-stage electric telescopic rod 6. The water pump 16 is electrically connected to the PLC controller 7. The provided water tank 15, water pump 16, and spray nozzle 17 cooperate. The water pump 16 is used to pump the water in the water tank 15 and spray it out through the spray nozzle 17 into the shielding box 3, realizing the spraying and dust-removing of the grooving position and the spraying and temperature-reducing treatment of the cutting disc 10.

[0033] The method of using this embodiment is as follows: the device is moved to the position where the groove is required on the road, and the closing distance value of the multi-stage electric telescopic rod 6 is pre-set by the PLC controller 7 according to the depth of the groove required, and then the multi-stage electric telescopic rod 6 is controlled by the PLC controller 7 to start forward, the water pump 16 is started, and the drive motor 9 is started. When the drive motor 9 is started, the cutting disc 10 is driven to rotate, and the multi-stage electric telescopic rod 6 drives the lifting plate 5 to move downward when the multi-stage electric telescopic rod 6 is started forward. The lifting plate 5 drives the cutting disc 10 to move downward in turn through the fixed plate 8 and the drive motor 9. At the same time, the lifting plate 5 drives the shielding box 3 to move downward in turn through the T-shaped guide rod 11 and the spring 12. When the shielding box 3 drives the ball 4 to move downward to contact with the road surface, it is blocked and restricted by it. At this time, the lifting plate 5 that continues to move downward drives the T-shaped guide rod 11 to compress the corresponding spring 12 downward, and uses the compressed spring 12 to elastically tighten the shielding box 3 downward. When the lifting plate 5 continues to move downward, it also drives the cutting disc 10 to continue to move downward, and drives the reflective sheet 14 moves downward, at this time, the rotating and downwardly moving cutting disc 10 moves downward from the protection box 3 to cut and groove the road surface. At this time, the laser distance measuring sensor 13 is affected by the protection box 3 and no longer follows it downward, and the distance between it and the reflective sheet 14 increases. This distance is the depth distance of the cutting disc 10 moving downward for cutting. The laser distance measuring sensor 13 detects the distance between it and the reflective sheet 14 in real time and transmits the distance value to the PLC controller 7. When the preset distance value is reached, the PLC controller 7 controls the multi-stage electric telescopic rod 6 to automatically close and stop moving downward. At this time, the personnel can push the device to move and perform the groove work. The downwardly moving protection box 3 can be used to surround and block the groove position, reduce the phenomenon of large amounts of dust scattering outward, and improve the environmental protection effect. By automatically measuring the cutting groove depth and automatically stopping the downward movement when the preset distance value is reached, it is convenient to automatically adjust and control the groove depth without the need for personnel to observe and judge the adjustment, thereby improving the degree of automation and convenience of adjustment and facilitating personnel use.

[0034] When the water pump 16 is started, water in the water tank 15 is extracted and sprayed into the shielding box 3 through the atomizing nozzle 17. The sprayed water is sprayed on the slotting position to reduce dust and on the cutting disc 10 to reduce temperature, so as to achieve the effect of integrated automatic dust reduction and cooling of the cutting disc 10 during slotting. The dust reduction by spraying is further improved to improve the environmental protection effect, and the cooling of the cutting disc 10 by spraying is improved to increase its service life.

[0035] After the grooving is completed, the multi-stage electric telescopic rod 6 is started in reverse to drive the lifting plate 5 to rise up. The lifting plate 5 drives the cutting disc 10 to move back upward and be stored in the protective box 3 through the fixed plate 8 and the driving motor 9 in turn. Then the lifting plate 5 that continues to move upward squeezes and drives the protective box 3 to rise, thereby achieving the effect of automatically storing and hiding the cutting disc 10 after use or when not in use, reducing the risk of it being accidentally damaged or accidentally scratching people, and improving safety in use.

[0036] Finally, it should be noted that the above are only preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features.
