As shown in fig. 3, the self-priming device includes a base 41, arc-shaped supporting

rods

421, 422, 423, 424, an arc-shaped suction cup group 43, four air pipes 44, a groove 45, two handles 46, four annular through holes 47, and four threaded columns 471. The arc-shaped suction cup group 43 is connected with the vacuum pump 5 through an air pipe. Wherein, the end parts of the arc-shaped supporting

rods

421, 422, 423 and 424 are welded with threaded columns 471, and the threaded columns 471 are inserted into the annular through holes, so that the four arc-shaped supporting rods can move back and forth on the annular through holes. When holes are drilled on the side and the top of the tunnel, the placing positions of the four supporting rods are determined according to the stress condition of the drilling machine, and the four supporting rods can be screwed and fixed by nuts matched with the threaded rods 471 after the positions are determined. The other end of each arc-shaped supporting rod is a sucker group 43, so that the problem that the connecting seams of the segments are not firmly adsorbed can be solved.

As shown in FIG. 4, a semicircular fixing plate 451 welded to the bottom of the groove is arranged in the groove 45, a threaded hole 454 is formed in the groove 451, one end of each of two guide iron rods 453 is welded to the side of the groove, the other end of each of the two guide iron rods is welded to the fixing plate 451, two through holes of a semicircular movable plate 452 are sleeved on the guide iron rods and can move back and forth on the guide iron rods, and a threaded hole is formed in each of 452, and the size and the position of the threaded hole are identical to those of the threaded hole. Angle measuring scales of 0-90 degrees are engraved at the positions of the semicircular fixed plate and the semicircular movable plate along the circular arcs, or common scales are engraved according to needs. When the screw rod 2 is fixed, 452 is firstly slid to the side edge of the groove of the fixed guide iron rod, then the threaded hole at the bottom of the screw rod is aligned with 454, and then 452 is slid to the position close to the screw rod 2 to fasten the screw rod by a screw.

As shown in fig. 5, the lower end of the screw rod 2 is a through hole 23 with a thread on the inner wall, a reference line 231 is arranged in the middle above the through hole, when vertically drilling, the reference line 231 is aligned with the center line of 452, when drilling an inclined hole, the reference line is aligned with the corresponding scale, and the two surfaces of the semicircular fixed plate and the semicircular movable plate are both provided with the same scale, which is convenient for users to use. At this time, the screw rod 2 is fixedly connected inside the groove 45 by using a nut corresponding to the threaded hole.

During the operation of punching, press clutch 16, then rotate screw rod 2 and make rig 1 descend to the drill bit 18 can aim at the position of punching, loosen clutch 16, open vacuum pump 5, adsorb this device on the operation section of jurisdiction, adsorb stable back, open the switch 15 of rig, the rig begins to work this moment, drill bit 18 is high-speed rotatory, the rig body begins to remove to the section of jurisdiction along screw rod 2, when dust collecting funnel 3 begins to contact the section of jurisdiction, spring 17 begins to be compressed, the piece that drill bit 18 produced from beginning to contact the section of jurisdiction to the end of punching all drops in dust collecting funnel. When the clutch 16 contacts the travel switch 22, that is, the drilling depth is reached, the drilling machine 1 stops working under the control of the travel switch, and at the moment, the gear driven by the motor still continues to rotate due to inertia; and the spring in the clutch 141 is compressed, the components driven by the clutch 141, including the small bevel gear 142, the large bevel gear 143, the gear 144 and the gear nut 21, stop rotating, at this time, the drilling machine 1 does not move along the screw rod 2 any more, even if the drill bit continues to rotate for a period of time due to the inertia of the gear, the drilling machine does not continue to advance towards the direction of the pipe piece, and the accurate drilling depth is ensured. At the moment, the screw rod 2 is held, the vacuum pump is closed, the device is taken down from the pipe piece, the iron hook 31 of the dust collecting funnel 3 is taken down from the circular ring of the spring 17, the hard transparent plastic baffle 32 is pulled out, the scraps are poured out, and the hard plastic baffle 32 is inserted back into the chute; the clutch 16 is pressed, the screw 2 is manually rotated to lift the drilling machine to a proper position, the clutch is released, the dust collecting hopper 3 is hung, and the next punching operation is ready to be carried out.

Because of the diameter of the shield structure is different in size, the length of the strut is determined according to the requirement. In the punching process, if a duct piece connecting seam is arranged around the punching position, the position of the arc-shaped supporting rod can be properly adjusted, so that the arc-shaped sucking disc group avoids the connecting seam; if the sound of the drill bit part is suddenly increased in the punching process, namely the drill bit 18 accidentally touches the steel bar, the steel bar must be timely processed, otherwise the steel bar is damaged, the clutch 16 should be immediately pressed, at the moment, the drilling machine 1 does not move continuously along the screw rod 2 any more, the drill bit 18 is protected from further touching the steel bar, then the drilling machine switch 15 is turned off, after the drill bit stops rotating, the clutch 16 is released, the vacuum pump 5 is turned off, the device is taken down, the screw rod 2 is manually rotated, the drilling machine is lifted to a proper position, and then the punching position is selected again.
