[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] A special drilling device for fire protection engineering installation includes a drilling mechanism 1 and a clamping mechanism 2, characterized in that the drilling mechanism 1 is connected to an angle adjustment mechanism 3.

[0023] The angle adjustment mechanism 3 includes a housing 31, in which a worm gear 33 and a worm 32 are provided. The worm gear 33 meshes with the worm 32. The central shafts at both ends of the worm 32 are respectively bearing connected to the housing 31. A handwheel 36 is fixedly connected to the end of the central shaft of the worm 32. The central shaft of the worm gear 33 is respectively bearing connected to the housing 31. The base 21 of the clamping mechanism 2 is fixedly connected to the housing 31 on one side; The lower end of the lead screw box 15 of the drilling mechanism 1 is fixedly connected to the central shaft of the worm gear 33.

[0024] The drilling mechanism 1 includes a lead screw box 15, a slider 17 slidably connected inside the lead screw box 15, a lead screw 16 threadedly connected to the slider 17, the end of the lead screw 16 movably connected to the end of the lead screw box 15, a handwheel 110 fixedly connected to the upper end of the lead screw box 15, a support plate 12 fixedly connected to the slider 17, a motor 11 fixedly connected to the upper side of the support plate 12, the output shaft of the motor 11 passing through and movably connected to the support plate 12, a chuck 13 fixedly connected to the end of the output shaft of the motor 11, and a drill bit 14 detachably fixedly connected to the chuck 13.

[0025] The clamping mechanism 2 includes a base 21, a lead screw groove 27 in the middle of the base 21, a bidirectional lead screw 24 movably connected to the inner side of the lead screw groove 27, the bidirectional lead screw 24 having threads with opposite helical directions at both ends, sliders 23 being threaded to both ends of the bidirectional lead screw 24, V-shaped clamps 22 being fixedly connected to the upper side of the sliders 23, and a knob 25 being fixedly connected to the end of the bidirectional lead screw 24.

[0026] The base 21 is threaded with a set screw 26, which can hold the bidirectional lead screw 24.

[0027] It should be noted that tightening the set screw 26 secures the bidirectional lead screw 24 to prevent it from rotating.

[0028] The two V-shaped clamps 22 are arranged with their openings facing each other. The upper part of the V-shaped clamps 22 is provided with a through groove 28 to prevent the drill bit 14 from colliding with the V-shaped clamps 22.

[0029] The pointer 34 is fixedly connected to the end of the central shaft of the worm gear 33, and the angle plate 35 is fixedly connected to the outside of the housing 31.

[0030] It should be noted that by observing that pointer 34 points to position 35 on the angle dial, the angle of drilling mechanism 1 can be determined. A scale 19 is provided on one side of the lead screw box 15, and a pointer 18 is fixedly connected to the support plate 12.

[0031] It should be noted that by observing the relative displacement between pointer 18 and scale 19, the depth of the borehole can be determined, thus avoiding damage to the fire-fighting pipeline due to excessive drilling.

[0032] The working principle is as follows: In use, first, to determine the required drilling angle, turn handwheel 36 to drive worm gear 32. Worm gear 32 drives worm wheel 33 to rotate, which in turn drives pointer 34 and drilling mechanism 1 to swing. Observe that pointer 34 points to the position of angle dial 35, indicating the desired drilling angle. Stop turning handwheel 36. Then, place the fire pipe between two V-shaped clamps 22, with drill bit 14 facing the desired drilling position. Turn knob 25 to drive double-acting screw 24 to rotate. Double-acting screw 24, through two sliders 23, drives the V-shaped clamps 22 to move closer to each other. When the two V-shaped clamps 22... 2. After clamping the fire-fighting pipe, tighten the set screw 26 to press the double-acting screw 24 to prevent it from rotating. Then, start the motor 11 to drive the drill bit 14 to rotate through the chuck 13. Turn the handwheel 110 to drive the screw 16 to rotate. The screw 16 drives the slider 17 and the support plate 12 to move, so that the drill bit 14 rotates and moves at the same time, thus drilling a hole in the fire-fighting pipe. Observe the relative displacement between the pointer 18 and the scale 19 to determine the drilling depth and avoid drilling too deep and damaging the fire-fighting pipe. After drilling is completed, turn off the motor and turn the handwheel 110 in the opposite direction to separate the fire-fighting pipe from the device.
