Description

Technical Field

[0001] This utility model relates to the field of drilling technology for PVC pipes used in mining, and specifically to a drilling device for PVC mining pipes. Background Technology

[0002] Mining PVC pipes are mainly used in mine tunnels for sealing gas boreholes, temporary pumping, and temporary drainage pipes. To monitor changes in gas concentration within the boreholes, a measuring port needs to be opened at the head of each PVC pipe. Currently, this is primarily done manually, requiring a large number of holes and consuming significant manpower and time. In the existing technology, Chinese Patent Publication No. CN217046725U proposes a drilling device for PVC pipes in coal mines. This device drills holes in the pipe using a threaded feed method and can adjust the position of the hole on the mine pipe. However, during the drilling process, different drill bits are required for different pipe diameters because the required hole size varies. A single drill bit is inconvenient for drilling different hole sizes according to the pipe diameter, and the adjustable drilling position is at a fixed distance, which restricts the drilling location and makes it inconvenient to drill at arbitrary positions. Utility Model Content

[0003] The purpose of this utility model is to solve the problems of inconvenience in drilling holes of different sizes according to the pipe diameter and inconvenience in drilling at any position. This utility model provides a PVC mining pipe drilling device.

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0005] A PVC mining pipe drilling device includes a U-shaped frame, with pipe fixing mechanisms on both sides of the U-shaped frame, and a receiving hole on the side wall of the U-shaped frame. An adjusting screw is fixedly installed in the receiving hole, and an adjusting screw is screwed into the adjusting screw. One end of the adjusting screw is provided with a toggle mechanism, and the other end of the adjusting screw is provided with a drill bit connection mechanism.

[0006] Preferably, the pipe fixing mechanism includes two supporting screw tubes, and positioning holes are symmetrically opened on the side wall of the U-shaped frame. Both supporting screw tubes are fixedly installed in the positioning holes, and a limit screw is screwed into the supporting screw tube. A clamping arc plate is rotatably installed at one end of the limit screw.

[0007] Preferably, multiple guide telescopic sleeves are symmetrically installed on the side wall of the U-shaped frame, with two guide telescopic sleeves distributed on the upper and lower sides of the limiting screw, and one end of the guide telescopic sleeve is fixedly installed on the clamping arc plate.

[0008] Preferably, the actuating mechanism includes a connecting block, one side of which is fixedly mounted on an adjusting screw, and an actuating rod is fixedly mounted on the side wall of the connecting block.

[0009] Preferably, the drill bit connection mechanism includes a connecting cylinder, one side of which is fixedly mounted on an adjusting screw, and a connecting drill bit is inserted into the connecting cylinder. Both the connecting cylinder and the connecting drill bit have locking screw holes on their side walls, and locking screws are screwed into the locking screw holes.

[0010] Preferably, a carrier box is fixedly installed on the side wall of the U-shaped frame, and a base block is slidably arranged inside the carrier box. Multiple tool placement holes are opened on the side wall of the base block, and a sealing cover plate is elastically hinged to the side wall of the carrier box.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. In this utility model, by setting up components such as clamping arc plates, connecting cylinders, and connecting drill bits, the locking screws on the connecting cylinder can be loosened, thereby removing the connecting drill bit and fixing a new drill bit. This allows the size of the drill bit to be adjusted according to the required drilling size. Furthermore, the two clamping arc plates are fastened to the pipe without being locked. Then, moving the U-shaped frame can drive the connecting drill bit to be adjusted and aligned with any position on the pipe. Finally, the clamping arc plates are locked, thereby enabling drilling at any position on the pipe. Attached Figure Description

[0021] like Figure 1-3 As shown, a PVC mining pipe drilling device includes a U-shaped frame 1. Pipe fixing mechanisms are provided on both sides of the U-shaped frame 1. The pipe fixing mechanisms include two supporting screw tubes 3. Positioning holes 2 are symmetrically opened on the side wall of the U-shaped frame 1. The two supporting screw tubes 3 are fixedly installed in the positioning holes 2, and a limiting screw rod 4 is screwed into the supporting screw tube 3. A clamping arc plate 5 is rotatably installed at one end of the limiting screw rod 4. The limiting screw rod 4 set in the drilling hole moves in conjunction with the supporting screw tube 3, so that the two clamping arc plates 5 can clamp and fix the pipe.

[0022] Multiple guide telescopic sleeves 6 are symmetrically installed on the side wall of the U-shaped frame 1. Two guide telescopic sleeves 6 are distributed on the upper and lower sides of the limiting screw 4, and one end of the guide telescopic sleeve 6 is fixedly installed on the clamping arc plate 5. The guide telescopic sleeves 6 can conveniently guide the movement of the clamping arc plate 5, thereby making the movement of the clamping arc plate 5 more stable.

[0023] The side wall of the U-shaped frame 1 has a receiving hole 8. An adjusting screw tube 9 is fixedly installed in the receiving hole 8, and an adjusting screw rod 10 is screwed into the adjusting screw tube 9. One end of the adjusting screw rod 10 is provided with a toggle mechanism, which includes a connecting block 17. One side of the connecting block 17 is fixedly installed on the adjusting screw rod 10, and a toggle rod is fixedly installed on the side wall of the connecting block 17. The toggle rod drives the connecting block 17 to rotate, which makes it easier for the operator to rotate the adjusting screw rod 10.

[0024] The other end of the adjusting screw 10 is provided with a drill bit connection mechanism. The drill bit connection mechanism includes a connecting cylinder 11. One side of the connecting cylinder 11 is fixedly installed on the adjusting screw 10, and a connecting drill bit 12 is inserted into the connecting cylinder 11. Both the side walls of the connecting cylinder 11 and the connecting drill bit 12 are provided with locking screw holes 13, and locking screws 14 are screwed into the locking screw holes 13. A bearing box 7 is fixedly installed on the side wall of the U-shaped frame 1, and a base block 16 is slidably arranged in the bearing box 7. Multiple tool placement holes 15 are provided on the side wall of the base block 16. A sealing cover plate is elastically hinged to the side wall of the bearing box 7. More spare drill bits can be stored in the tool placement holes 15 through the base block 16.

[0025] In summary: When drilling a pipe, first take out the spare drill bit from the bearing box 7 according to the required hole size, then loosen the locking screw 14 on the connecting sleeve 11 to remove the connecting drill bit 12 from the connecting sleeve 11. Then install the spare drill bit and fix it again with the locking screw 14. Next, close the two clamping arc plates 5 on the U-shaped frame 1 and fasten them to the outer wall of the pipe. Then push the U-shaped frame 1 to make the clamping arc plates 5 rotate or move on the pipe. This way, the clamping arc plates 5 on both sides will prevent the U-shaped frame 1 from falling off the pipe. Next, align the drill bit tip with the position where the hole needs to be opened, and then rotate the limit screw 4 to drive the clamping arc plates 5 to be fully clamped. Then, the operator only needs to push the lever to drive the connecting block 17 to rotate. This will cause the connecting block 17 to drive the adjusting screw 10 and the adjusting screw tube 9 to rotate, which will cause the adjusting screw 10 to drive the drill bit to move down to open the hole. This allows for easy hole opening at any position in the pipe.

[0026] The foregoing description enables those skilled in the art to implement or use this invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this invention. Therefore, this invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
