It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant invention and are not intended to limit the invention. It should also be noted that, for ease of description, only portions relevant to the invention are shown in the accompanying drawings.

[0038] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0039] Reference Figures 1 to 4 As shown, the present invention provides a high-altitude drilling device, comprising: a movable base 1, a column assembly 2, a drilling device 3, a driving structure and a non-return mechanism.

[0040] In this embodiment, the column assembly 2 is vertically arranged on the upper part of the movable base. The height of the column assembly is adjustable.

[0041] See Figure 1 and Figure 2 The column assembly 2 includes a socket sleeve 21 and a connecting rod 22.

[0042] The socket sleeve 21 is vertically arranged on the movable base 1. The upper part of the socket sleeve 21 is provided with a strip hole, which is arranged along the axial direction of the socket sleeve 21. The lower end of the plug rod 22 is movably inserted into the socket sleeve 21.

[0043] The drilling device 3 is detachably mounted on the upper end of the plug rod 22;

[0044] See Figure 2 The driving structure includes a rack 41, an axle 42 and a gear 43.

[0045] A rack 41 is fixed to the lower end of the splice rod 22. The strip-shaped hole in the socket 21 aligns with the rack 41. An axle 42 is rotatably mounted on the exterior of the socket 21. A gear 43 is coaxially mounted on the axle 42. One side of the gear 43 movably passes through the strip-shaped hole and meshes with the rack 41.

[0046] Continue reading Figure 2 The anti-return mechanism includes a support frame 51, a receiving box 52 and a length-adjustable support member 53.

[0047] The support frame 51 is rotatably mounted on the axle 42 along the circumference of the gear 43. It is hingedly connected between the support frame 51 and the socket sleeve 21. The storage box 52 is mounted on the support frame 51. The support member 53 is tilted. The upper end of the support member 53 is mounted on the exterior of the socket sleeve 21. The lower end of the support member 53 is tilted downward and outward, supporting the storage box 52. A guide hole is formed in the wall of the storage box 52, corresponding to the circumferential surface of the gear 43. A push rod 521 is slidably mounted in the guide hole. A tooth block 522 is connected to one end of the push rod 521. The tooth block 522 has teeth formed thereon for meshing with the gear 43. An elastic push member 524 is mounted between the other end of the push rod 521 and the inner side of the storage box 52 wall. The storage box 52 wall is perforated. A shift lever 523 is adjustably mounted in the perforation of the storage box 52 wall. The shifting rod 523 is connected to the push rod 521 .

[0048] The high-altitude drilling device of the present invention raises and lowers the plug-in rod through the driving structure, thereby adjusting the height of the column assembly. During construction, the drill bit of the drilling equipment can be quickly pressed against the opening in the ceiling. On the other hand, after the drill bit is pressed against the opening, the length of the support member is adjusted based on the preset depth of the opening, and the support member of the anti-return mechanism is extended or lengthened to support the accommodating box downward to avoid the reverse rotation of the gear and cause the plug-in rod to descend. After the drill bit rotates and drills, the wheel shaft continues to rotate forward to make the drill bit drill upward. When the accommodating box abuts against the socket sleeve, the drilling equipment is closed. At this time, the plug-in rod is lowered to make the drill bit exit the opening, and the drilling depth is also adapted to the preset depth of the drilling.

[0049] The high-altitude drilling device of the present invention realizes the high efficiency of the use of drilling equipment in drilling holes while meeting the requirements of convenient, safe and reliable construction, reduces workload, reduces costs, reduces the time wasted by construction workers in repeatedly climbing high, improves the overall construction efficiency of the construction site, and reduces the safety risks of high-frequency climbing. At the same time, the device realizes turnover utilization.

[0050] See Figure 4 The movable base 1 includes: a base block 11, a folding arm 12, a roller 13 and a locking member 14.

[0051] The socket sleeve 21 is vertically mounted at the center of the plane of the base block 11. The base block 11 is cube-shaped. The socket sleeve is positioned on the central axis of the base plate. The socket sleeve is coaxial with the base block. At least three receiving grooves are formed on the outer edge of the base block 11. The outer ends of the receiving grooves, away from the center of the plane, extend through the base block 11.

[0052] In this embodiment, there are four accommodating grooves, which are arranged at equal intervals along the outer edge of the base block.

[0053] The number of folding arms 12 is adapted to the number of accommodating slots. One end of the folding arm 12 is reversibly mounted on the outer end of the accommodating slot. Specifically, a fixed shaft is mounted between the opposing side walls of the accommodating slot. One end of the folding arm has an axial hole. The fixed shaft rotatably passes through the axial hole. The fixed shaft is disposed at the inner end of the accommodating slot, near the center of the plane of the base block.

[0054] The roller 13 is mounted on the other end of the folding arm 12. The locking member 14 is mounted on the folding arm 12. The locking member 14 is used to lock the base block 11.

[0055] Continue reading Figure 4 The folding arm 12 is provided with a waist-shaped hole. The waist-shaped hole is arranged along the length of the folding arm 12. The locking member 14 is slidably mounted in the waist-shaped hole. An elastic member is connected between the locking member 14 and the inner wall of one end of the waist-shaped hole. A limit notch is formed on the end surface of the outer end. The end of the locking member 14 extends outside the waist-shaped hole and is embedded in the limit notch.

[0056] In this embodiment, the elastic member is a spring. A limiting groove is formed on the upper surface of the base block. The limiting groove extends through the accommodating groove and is perpendicular to the accommodating groove. When the locking member is pushed out of the limiting notch and the folding arm is tilted upward, so that the folding arm approaches the socket, the locking member aligns with the limiting groove and, under the pulling force of the elastic member, is embedded in the limiting groove, thereby locking the folding arm in the folded state. Figure 4 The folding arms of the mobile base are shown in an extended state, ie in a working state.

[0057] Continue reading Figure 1 A supporting member is mounted on the upper end of the connecting rod 22. In this embodiment, the supporting member is a rod. The rod is a square tube. The lower portion of the drilling instrument 3 is removably secured to the supporting member via a locking attachment. The upper portion of the drilling instrument 3 is removably secured to the upper end of the connecting rod 22 via a locking attachment. The locking attachment is a lashing strap.

[0058] See Figure 2 and Figure 3 The support frame 51 is in the shape of a gate. Specifically, the support frame 51 includes: a base plate and two connecting plates.

[0059] The base plate is disposed opposite the circumferential surface of the gear 43. The base plate is coaxially disposed with the axle 42. The storage box 52 is fixedly mounted on the side of the base plate away from the gear 43. The base plate has a through hole connected to the guide hole. The push rod 521 is movably inserted into the through hole. Two connecting plates are disposed opposite the end surfaces of the gear 43. One end of the connecting plate is connected to one end of the base plate. The other end of the connecting plate has an axial hole. The axle 42 is rotatably inserted into the axial hole.

[0060] In this embodiment, the sidewalls of the storage box have arc-shaped perforations. Specifically, the perforations are J-shaped and extend along the length of the storage box. The elastic pusher 524 is a spring. This elastic pusher constantly applies a pushing force to the push rod toward the circumferential surface of the gear. The position of the lever in the perforation allows the gear block to disengage or engage with the gear.

[0061] In this embodiment, the wheel axle 42 is connected to a handle, which is arranged along the radial direction of the wheel axle 42. By rotating the handle, the wheel axle is rotated, thereby driving the gear to rotate.

[0062] The present invention provides a construction method of a high-altitude drilling device, comprising the following steps:

[0063] S1: Move the movable base 1 to directly below the opening of the ceiling so that the drill bit of the drilling device 3 is aligned with the opening.

[0064] S2: The shaft 42 of the driving mechanism is rotated forward to raise or lower the connecting rod 22 of the vertical rod assembly so that the drill bit 31 abuts against the opening in the ceiling.

[0065] S3: Based on the preset depth of the opening, the length of the support member 53 is adjusted to support the accommodating box 52 of the anti-return mechanism.

[0066] S4: Adjust the position of the lever 523 in the through hole on the wall of the accommodating box 52 so that the push rod 521 moves toward the circumferential surface of the gear 43 under the push of the elastic push member 524 of the anti-return mechanism to make the tooth block 522 of the anti-return mechanism engage with the gear 43, thereby preventing the wheel shaft 42 from rotating in the opposite direction.

[0067] S5: Turn on the drilling device 3 and continue to rotate the wheel shaft 42 in the forward direction to make the connecting rod 22 continue to rise, thereby making the drill bit 31 drill into the ceiling.

[0068] S6: After the accommodating box 52 is turned downward and abuts against the socket sleeve 21, the drilling device 3 is closed so that the drilling depth of the drill bit is adapted to the preset depth.

[0069] The high-altitude drilling device and construction method of the present invention can not only quickly set the drilling equipment at the opening of the ceiling, avoiding frequent climbing by construction workers, but also limit the accommodating box through the support member so that the tooth block can engage with the gear, avoiding reverse rotation of the gear. The rotation angle of the gear is used to determine the drilling depth of the drill bit of the drilling equipment, thereby improving the efficiency of opening holes in the ceiling and effectively improving the opening quality.
