[0024] In response to the above problems, an embodiment of the present application provides an easily adjustable highway construction drilling device that can adjust the drilling depth. The drilling depth can be automatically controlled during drilling without the need for visual observation, thereby facilitating continuous drilling.
[0025] The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.
[0026] See also Figure 1 The adjustable highway construction drilling device includes a base plate 1, a drilling rig 2, a top plate 3, a punching drill bit 11, and a drilling depth limiting bracket; the drilling rig 2 is fixedly connected to the center of the top surface of the base plate 1, the top of the drilling rig 2 is fixedly connected to the top plate 3, the output end of the drilling rig 2 is fixedly connected to the punching drill bit 11, and the drilling depth limiting bracket for adjusting the drilling depth is installed on the outside of the drilling rig 2 and the punching drill bit 11 through the base plate 1 and the top plate 3.
[0027] During operation, the drilling depth of the punching drill bit 11 of the drilling machine 2 can be adjusted by the drilling depth limiting bracket.
[0028] In some embodiments, see Figure 2 The drilling depth limiting bracket includes a guide sleeve 5, which is fixedly connected between the four corners of the bottom plate 1 and the top plate 3. The inner wall of the guide sleeve 5 is slidably connected with a sliding plate 12. The center of the bottom surface of the sliding plate 12 is fixedly connected with three guide rods 6 and a lead screw 14. The bottom of the guide rod 6 and the lead screw 14 respectively pass through the bottom surface of the bottom plate 1 and are fixedly connected with a connecting rod 7. The lower ends of the four connecting rods 7 face the center and are fixedly connected with a positioning plate 8. A circular hole is opened in the middle of the positioning plate 8, and a drilling drill bit 11 passes through the circular hole of the positioning plate 8. The outer wall of the lead screw 14 is threadedly connected with an adjusting nut 9, and the top surface of the adjusting nut 9 is fixedly connected with a positioning stop head 10.
[0029] Then, after the positioning stop head 10 hits the bottom surface of the bottom plate 1, the drilling depth of the drilling bit 11 is limited, the drilling is completed, and the drill rig 2 is then pulled upwards to pull out the drilling bit 11.
[0030] In some embodiments, the diameter of the sliding plate 12 is adapted to the diameter of the inner wall of the guide sleeve 5, an air vent is provided at the top of the guide sleeve 5, and a reset spring 13 is connected between the top of the inner wall of the guide sleeve 5 and the top surface of the sliding plate 12, and the length of the reset spring 13 after reset is adapted to the length of the guide sleeve 5.
[0031] During operation, the air pressure is balanced through the air vents, and the three guide bars 6 and the top of a lead screw 14 are pushed by the pushing force of the return spring 13, so that the drill rig 2 can be pushed up to pull back the drilling bit 11, making it easier to pull out the drill rig 2 and reducing the burden on the operator.
[0032] In some embodiments, the guide rod 6 and the lead screw 14 are of equal length and are compatible with the depth of the inner wall of the guide sleeve 5 and the length of the punching drill bit 11; the diameter of the circular hole of the positioning plate 8 is larger than the diameter of the punching drill bit 11, and the bottom surface of the positioning plate 8 is fixedly connected to a non-slip layer, and the outer wall of the lead screw 14 is marked with a length scale.
[0033] During operation, the guide length of the guide rod 6 and the lead screw 14 matches the drilling depth of the drilling bit 11, so that the length scale on the outer wall of the lead screw 14 can be conveniently adjusted and measured. The anti-slip layer can make the positioning plate 8 press against the road surface, thereby improving stability and stability during drilling. The length scale is convenient for observing and adjusting the length.
[0034] In some embodiments, pull handles 4 are fixedly connected to both sides of the top surface of the top plate 3 , the two pull handles 4 are symmetrically arranged, and the outer walls of the pull handles 4 are fixedly connected to anti-slip sleeves.
[0035] During operation, the handle 4 and the anti-slip sleeve are pulled to facilitate stable pulling of the handle 4 so as to control the drilling machine 2 .
