Technical Field

[0001] The utility model relates to the technical field of drilling machines, in particular to a drilling machine for road surface repair. Background Art

[0002] Pavement damage can be generally divided into two categories: structural damage and functional damage. Structural damage leads to a decrease in the bearing capacity of the pavement structure, which manifests itself in the form of various structural cracks, while functional damage affects driving quality and safety, manifested in a decrease in the pavement's service capacity, flatness, and anti-skid performance.

[0003] A Chinese patent with publication number CN208587099U discloses a drilling machine for road repair, including a workbench, a control panel, a motor, a worm gear, a driven wheel, a driving wheel, a sleeve, a rotating rod, a drill bit, a telescopic rod and a limit spring, characterized in that: a square hole is opened on the top of the workbench, an equipment box is slidably connected in the square hole, a motor is fixedly connected to the inner wall of the top of the equipment box, a driving wheel is sleeved and fixed on the output shaft of the motor, a sleeve is provided on one side of the motor inside the equipment box, the top of the sleeve is rotatably connected to the inner wall of the equipment box through a bearing, a driven wheel is sleeved and fixed on the outer side of the sleeve, the driving wheel is meshed and connected with the driven wheel, the bottom of the sleeve passes through the inside of the equipment box and is slidably connected with a rotating rod, and a drill bit is fixedly connected to one end of the rotating rod away from the sleeve. The drilling machine can not only adjust the height of the drill bit, but also reduce the vibration of the drill bit during drilling, protect the drill bit, and extend the service life of the drilling machine.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0033] like Figure 1-Figure 4 As shown, the drilling machine for road repair proposed by the utility model comprises:

[0034] Base 1;

[0035] A sliding member 6 is slidably disposed on the base 1;

[0036] The rotating bracket 10 is arranged on the base 1;

[0037] A lifting bracket 11 is rotatably arranged on the rotating bracket 10;

[0038] A lifting member 12 is slidably disposed on the lifting bracket 11;

[0039] The motor housing 14 is slidably disposed on the lifting bracket 11;

[0040] A rack 17, arranged on the lifting bracket 11;

[0041] The driving gear 16 is rotatably mounted on the motor housing 14 and meshed with the rack 17 to control the motor housing 14 to move up and down and slide;

[0042] The drilling support 18 is slidably disposed on the lifting support 11 .

[0043] The base 1 is provided with a handle 2 , a plurality of ground nails are provided on the base 1 , a plurality of rollers 3 are rotatably provided on the base 1 , and a sliding groove 5 is provided on the base 1 .

[0044] The sliding member 6 is provided with a threaded sleeve 7, the threaded sleeve 7 is provided with an internal thread, the threaded sleeve 7 is threaded with a threaded rod 8, the threaded rod 8 is provided with a rotating handle, and a locking member is provided at the bottom of the threaded rod 8. The threaded rod 8 passes through the sliding groove 5, and the locking member contacts and squeezes the bottom of the base 1.

[0045] The sliding member 6 is provided with a threaded sleeve 7, the threaded sleeve 7 is provided with an internal thread, the threaded sleeve 7 is threaded with a threaded rod 8, the threaded rod 8 is provided with a rotating handle, and a locking member is provided at the bottom of the threaded rod 8. The threaded rod 8 passes through the sliding groove 5, and the locking member contacts and squeezes the bottom of the base 1.

[0046] The drilling bracket 18 is provided with a drilling motor 19 , the drilling motor 19 is provided with a rotating shaft 20 , and a drill bit 21 is provided on the other end of the rotating shaft 20 .

[0047] A rotating connecting rod 9 is rotatably provided on the threaded sleeve 7 , and the rotating connecting rod 9 is rotatably connected to the lifting bracket 11 .

[0048] The ground nail 4 is provided with a wear-resistant layer.

[0049] In this embodiment, the present device can effectively improve the stability and efficiency of the drilling process. Compared with the traditional device, the present device can facilitate the rotation and folding effect of the lifting bracket 11 through the combination of the rotating bracket 10 and the lifting bracket 11, thereby ensuring the rotation and folding effect of the present device. The rotation locking effect of the sliding member 6 and the threaded rod 8 can effectively improve the sliding locking stability of the present device.

[0050] When the device is in working state, the combination of the roller 3 and the handle 2 can facilitate the movement of the base 1, thereby reducing the difficulty of moving the device, and the sliding member 6 can prevent the lifting bracket 11 from accidentally rotating.

[0051] When the device is moved to a suitable position, the sliding member 6 can slide freely by unlocking the threaded rod 8, and the lifting bracket 11 can be rotated under the sliding of the sliding member 6 by rotating the connecting rod 9, thereby achieving the transmission effect of the device. When the lifting bracket 11 is rotated to a suitable position, the threaded rod 8 is rotated so that the locking member at the bottom of the base 1 presses the base upward, thereby achieving the locking effect on the sliding member 6 and the rotation locking effect of the lifting bracket 11.

[0052] When the rotation position of the lifting bracket 11 is fixed, the driving gear 16 is driven to rotate by the double-headed motor 15, so that the vertical lifting effect of the motor bracket 14 can be achieved through the combination of the driving gear 16 and the rack 17. The motor housing 14 drives the lifting member 12 to rise and fall vertically through the spring 13, thereby achieving the effect of driving the drilling bracket 18 to rise and fall and slide. The lifting transmission through the spring 13 can effectively improve the shock absorption effect of the device. The drilling motor 19 drives the rotating shaft 20 to rotate, thereby drilling through the drill bit 21, realizing the drilling effect of the device.

[0055] The sliding protrusion can limit the sliding process of the sliding member 6, thereby ensuring the sliding stability of the device and reducing the risk of the rotating connecting rod 9 breaking due to excessive sliding.
