[0036] Example 1

[0037] As shown in Figures 1, 2, 3, and 4, an HDPE high-pressure pipe drilling device includes:

[0038] Limiting pad 12; The top surface of the limiting pad 12 is provided with a through groove, the cross section of which is an arc-shaped fan-shaped surface adapted to the cross section of the HDPE high-pressure pipe 8, and the HDPE high-pressure pipe 8 is slidably arranged in the through groove.

[0039] Support plate 1; Support plate 1 is vertically fixed;

[0040] A rotary reciprocating motion mechanism is installed on the support plate 1. The rotary reciprocating motion mechanism includes an actuating end and a punching end. The punching end is positioned facing the HDPE high-pressure pipe 8 in the through groove. The actuating end and the punching end are rotatably connected. When the actuating end drives the punching end to move to the lower extreme position, the punching end rotates and inserts into the cavity of the HDPE high-pressure pipe 8. When the actuating end drives the punching end to move to the upper extreme position, the punching end rotates out of the cavity of the HDPE high-pressure pipe 8.

[0041] Moving mechanism; The moving mechanism is fixedly installed and is used to drive the HDPE high-pressure pipe 8 to slide along the through groove.

[0042] In this embodiment, a limiting pad 12 is provided to restrict the lateral displacement of the HDPE high-pressure pipe 8, preventing the HDPE high-pressure pipe 8 from moving laterally during drilling. The actuating end of the rotary reciprocating motion mechanism can drive the drilling end to perform finger reciprocating motion. When the actuating end drives the drilling end to move to the lower extreme position, the drilling end rotates and inserts into the cavity of the HDPE high-pressure pipe 8. When the actuating end drives the drilling end to move to the upper extreme position, the drilling end rotates out of the cavity of the HDPE high-pressure pipe 8. This application uses a rotary insertion method to drill the HDPE high-pressure pipe 8. Compared with direct insertion, the insertion method of this application is more efficient, the longitudinal resistance of rotary insertion is smaller, and less energy is consumed.

[0043] Example 2

[0044] The difference between this embodiment and Embodiment 1 is that, as shown in Figures 1, 2, and 4, the punched end includes:

[0045] Grooved drill rod 2; Grooved drill rod 2 is an internal grooved spiral drill rod. The first end of the grooved drill rod 2 is rotatably connected to the actuating end. The second end of the grooved drill rod 2 is a drill bit structure. The second end of the grooved drill rod 2 is set to the HDPE high-pressure pipe 8 in the through groove. The material of the grooved drill rod 2 is stainless steel.

[0046] Lead block 3; Lead block 3 is fixedly installed on support plate 1. Lead block 3 is provided with threaded through hole that matches the thread on the outer wall of grooved drill rod 2. Grooved drill rod 2 is inserted into the threaded through hole. When the actuating end applies pressure or tension to grooved drill rod 2, grooved drill rod 2 rotates to approach or move away from HDPE high-pressure pipe 8. The length of threaded through hole in lead block 3 is one lead length of grooved drill rod 2. Lubricating fluid is coated in threaded through hole.

[0047] In this embodiment, the grooving drill rod 2 is inserted into the threaded through hole. When the actuating end applies pressure or tension to the grooving drill rod 2, the grooving drill rod 2 is pressed into contact with the threaded through hole, and the grooving drill rod 2 rotates along the thread direction. At the same time, the first end of the grooving drill rod 2 is rotatably connected to the actuating end. The rotation of the grooving drill rod 2 is not transmitted to the actuating end. The length of the threaded through hole is one lead length of the grooving drill rod 2 to avoid excessive contact surface and increased resistance. The threaded through hole is coated with lubricant to reduce the friction between the grooving drill rod 2 and the threaded through hole.

[0048] Example 3

[0049] The difference between this embodiment and embodiment 2 is that, as shown in Figures 1, 2, and 4, the actuating end includes:

[0050] First motor 13; the top end of the first motor shaft 6 passes through the support plate 1;

[0051] Rocker arm 7; The first end of rocker arm 7 is provided with a mounting through hole, the top end of the rotating shaft 6 of the first motor is inserted into the mounting through hole for fixed installation, the second end of rocker arm 7 is provided with a connecting through hole, a bearing is provided in the connecting through hole, and the outer ring of the bearing is fixedly connected to the connecting through hole.

[0052] Drive rod 5; The first end of drive rod 5 is provided with a mounting protrusion perpendicular to drive rod 5, and the inner ring of the bearing is fitted on the mounting protrusion. The second end of drive rod 5 and the first end of grooving drill rod 2 form a universal ball joint structure 4.

[0053] In this embodiment, when the shaft 6 of the first motor rotates, the rocker arm 7 rotates in a circular motion around the shaft 6 of the first motor. At the same time, the first end of the drive rod 5 is rotatably connected to the second end of the rocker arm 7 through a bearing. The second end of the drive rod 5 and the first end of the grooving drill rod 2 form a universal ball joint structure 4. Under the limiting action of the guide block 3, the drive rod 5 will convert the circular motion of the rocker arm 7 into the linear motion of the grooving drill rod 2. The entire rotation cycle is shown in (a), (b), (c) and (d) of Figure 4.

[0058] In this embodiment, the entire drilling process can be controlled by the controller to start and stop the second motor 11 and the rotary reciprocating motion mechanism for progress control. First, the second motor 11 is started, so that the part of the HDPE high-pressure pipe 8 that needs to be drilled is moved below the rotary reciprocating motion mechanism. Then, the rotary reciprocating motion mechanism is started to drill the HDPE high-pressure pipe 8. Then, the rotary reciprocating motion mechanism is turned off. Repeating the above steps can complete the drilling operation. Alternatively, the rotation speed of the second motor 11 can be set, and the reciprocating cycle of the rotary reciprocating motion mechanism can be set to achieve continuous drilling of the HDPE high-pressure pipe 8 without stopping the machine.
