Description

Technical Field

[0001] The present invention relates to the technical field of corrugated pipe processing, and more specifically, to a pulling and opening device applied to a corrugated pipe. Background Art

[0002] The corrugated pipes on the market are all made by the extrusion molding production process. During the extrusion molding process, due to the lack of corresponding special pipe hole-making equipment on the market, most of the holes are made by hand drills. Moreover, when making holes manually, the production efficiency is low and it is difficult to adapt to large-scale assembly line production operations, which increases labor costs. In addition, manual hole-making is prone to work-related accidents.

[0003] Patent CN106272689A discloses a corrugated pipe drilling device, including a working plate, an electric drill and an electric drill driving device arranged on the working plate, wherein the working plate is provided with a through hole for penetrating the corrugated pipe, and the drill bit direction of the electric drill is consistent with the radial direction of the through hole; the electric drill driving device is connected to the electric drill and is used to drive the electric drill forward or backward. The drill bit direction of the electric drill of the present invention is consistent with the radial direction of the corrugated pipe, thereby realizing radial processing of circular holes in double-wall or single-wall corrugated pipes, and at least two groups of electric drills are distributed on the working plate. and an electric drill driving device, the electric drill and the electric drill driving device are evenly arranged on the working plate, and also include a bellows driving assembly for driving the bellows to move axially, the bellows driving assembly includes a roller, a roller bracket, a roller driving motor, a roller bracket sliding guide rail and a roller driving device, the roller bracket sliding guide rail is arranged on the working table, the lower end of the roller bracket is arranged on the roller bracket sliding guide rail, the roller is located at the upper end of the roller bracket, the rotating shaft of the roller driving motor passes through the roller bracket and is connected to the roller; the roller driving device is connected to the roller bracket. However, in the above scheme, the pulling and opening of the pipe cannot be automatically completed. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art that pipes cannot be automatically fed and opened, and to provide a pulling and opening device for corrugated pipes, which can continuously perform pulling and opening operations on pipes.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] Provided is a traction and hole-opening device for a corrugated pipe, comprising a first mounting frame, a traction mechanism, a drilling mechanism, a controller and a sensor system for detecting the position of the corrugated pipe, wherein the traction mechanism, the drilling mechanism, the controller and the sensor system are all mounted on the first mounting frame, the traction mechanism, the drilling mechanism and the sensor system are all connected to the controller, and the traction mechanism pulls the corrugated pipe to the drilling mechanism.

[0007] The traction and hole-drilling device applied to the corrugated pipe of the present invention moves the pipe to the traction mechanism, and the sensor system detects that the pipe has reached the traction mechanism and transmits a signal to the controller. The controller controls the traction mechanism to start, and the traction mechanism pulls the pipe to move toward the drilling mechanism. When the pipe moves to the drilling station, the sensor system transmits a signal to the controller, and the controller controls the traction mechanism to pause, and the drilling mechanism to start, and the pipe is drilled. After one drilling is completed, the controller controls the traction mechanism to restart, and the traction pipe continues to move until the sensor system detects that the pipe has reached the next station, and the cycle is repeated until the drilling of the pipe is completed.

[0008] Furthermore, the sensor system includes a feed start sensor, a drilling start sensor and a feed end sensor, wherein the feed start sensor is arranged at the front end of the first mounting frame, the drilling start sensor is arranged on the first mounting frame, and the feed end sensor is arranged at the rear end of the first mounting frame. The direction opposite to the moving direction of the pipe is the front, and the direction the same as the moving direction of the pipe is the rear; when the feed start sensor detects that the pipe reaches the front end position of the traction mechanism, it transmits a signal to the controller, and the controller controls the pipe to move toward the drilling mechanism; when the drilling start sensor detects that the pipe reaches a drilling station, the controller controls the drilling mechanism to drill; when the feed end sensor detects that the front end of the pipe leaves the rear end of the traction mechanism, that is, when the pipe is separated from the traction mechanism, the controller controls the traction mechanism to stop working.

[0009] Furthermore, it also includes a clamping mechanism for clamping and positioning the corrugated pipe, the clamping mechanism is installed on the first mounting frame, the clamping mechanism is connected to the controller, and the traction mechanism, the drilling mechanism and the clamping mechanism are arranged in sequence. When the sensor system detects that the pipe reaches the drilling station, the controller controls the clamping mechanism to clamp the pipe to prevent the pipe from continuing to move due to inertia, resulting in inaccurate drilling position.

[0010] Furthermore, the sensor system also includes a trough position sensor for sensing the trough position of the pipe, the trough position sensor is arranged on the drilling mechanism, and the trough position sensor is connected to the controller. When the trough position sensor detects that the trough of the pipe reaches the drilling position of the drilling mechanism, it transmits a signal to the controller, the traction mechanism stops working, the clamping mechanism clamps the pipe, and the controller controls the drilling mechanism to drill in the trough of the pipe; when the trough is not detected, the traction mechanism continues to move until the trough is detected; and the automated drilling operation of the trough of the pipe can be realized.

[0011] Furthermore, the first mounting frame is provided with two or more drilling mechanisms, each of which is arranged along the axial direction of the pipe. By providing two or more drilling mechanisms, holes can be drilled simultaneously at different positions along the axial direction of the pipe, thereby improving drilling efficiency.

[0012] Furthermore, it also includes an adjustment mechanism for adjusting the horizontal position of the drilling mechanism, the adjustment mechanism is installed on the first mounting frame, and the adjustment mechanism is connected to the drilling mechanism. When drilling holes in different pipes, the distances of the holes along the axis of the pipe may be different. For example, the different spacings between the troughs lead to different hole spacings. The adjustment mechanism is used to adjust the horizontal position of the drilling mechanism, change the distance between the drilling mechanisms, and adjust the drilling spacing, so that when one drilling mechanism reaches the drilling position, the other drilling mechanisms also reach the correct drilling position, thereby increasing the applicability of the device to different pipes.

[0013] Furthermore, the sensor system further includes a drilling pause sensor, which is arranged on the first mounting frame and connected to the controller. The direction opposite to the moving direction of the pipe is the front direction, and the direction consistent with the moving direction of the pipe is the rear direction. When drilling a pipe with an expanded opening, when the drilling pause sensor detects that the expanded opening position of the pipe reaches the drilling mechanism, the controller controls the drilling mechanism to suspend operation to avoid interference between the drilling mechanism and the expanded opening of the pipe.

[0014] Furthermore, the traction mechanism includes two or more traction devices and a second driving device for driving the traction devices to move closer to or away from each other, the second driving device is installed on the first mounting frame, the traction device is connected to the second driving device, the traction device clamps the pipe, and the driving directions of the traction devices in each group are the same. When traction pipes, two or more traction devices are placed in a straight line, the pipes are moved between the traction mechanisms, the driving mechanisms in the two or more traction devices drive the traction mechanisms to clamp the pipes, the traction mechanisms drive the pipes to move, and when the expansion position of the pipe moves to the traction mechanism of a traction device, the driving mechanism of the traction device drives the traction mechanisms to separate from each other, loosen the pipes to avoid the expansion position of the pipes, and the traction mechanisms of other traction devices continue to pull the pipes, thereby achieving continuous clamping and traction of the pipes while avoiding the expansion of the pipes, thereby improving work efficiency.

[0015] Furthermore, the sensor system also includes a flaring sensor for sensing the flaring position of the pipe, the flaring sensor is arranged on the first mounting frame, the flaring sensor is connected to the controller, and the controller is connected to the second driving device. When the flaring sensor senses that the flaring of the pipe reaches the front of the traction mechanism, it transmits a signal to the controller, and the controller controls the driving mechanism to drive the traction mechanisms away from each other to avoid the flaring position of the pipe, thereby realizing automatic flaring of the pipe to avoid flaring, saving labor and improving work efficiency.

[0016] Further, the traction device includes a first traction device, a second traction device and a third traction device, the second driving device includes a first telescopic mechanism, a second telescopic mechanism and a third telescopic mechanism, the first telescopic mechanism, the second telescopic mechanism and the third telescopic mechanism are installed on the first mounting frame, the first traction device, the second traction device and the third traction device are connected to the output ends of the first telescopic mechanism, the second telescopic mechanism and the third telescopic mechanism respectively, and the first traction device, the second traction device and the third traction device are centrally symmetrically distributed. Move the pipe between the three groups of traction devices, adjust the telescopic amounts of the first telescopic mechanism, the second telescopic mechanism and the third telescopic mechanism until the first traction device, the second traction device and the third traction device clamp the pipe, because the three groups of traction devices are axially symmetrically distributed, the axis of the pipe coincides with the symmetry axis of the traction device, so that the pipe is evenly stressed and the traction process is more stable.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The traction and hole-opening equipment applied to the corrugated pipe of the present invention: 1. Through the cooperation of the traction mechanism, the drilling mechanism and the sensor system, the traction and hole-opening operations of the pipe can be automatically completed; 2. The pipe can be automatically positioned at an accurate drilling position for drilling, and when drilling the corrugated pipe, the trough position can be accurately positioned; 3. When drilling the pipe with the expanded opening, the traction mechanism and the drilling mechanism can automatically avoid the expanded opening of the pipe, and the traction and hole-opening operations can be continuously performed to improve the work efficiency.

[0029] Embodiment 1

[0030] like Figure 1 , Figure 2The figure shows a first embodiment of the traction and hole-opening device applied to a corrugated pipe of the present invention, comprising a first mounting frame 6, a traction mechanism 1, a drilling mechanism 2, a controller and a sensor system 3 for detecting the position of the corrugated pipe, wherein the traction mechanism 1, the drilling mechanism 2, the controller and the sensor system 3 are all mounted on the first mounting frame 6, the traction mechanism 1, the drilling mechanism 2 and the sensor system 3 are all connected to the controller, and the traction mechanism 1 pulls the corrugated pipe to the drilling mechanism 2.

[0031] The traction and hole-opening device applied to the corrugated pipe of the present invention moves the pipe 5 to the traction mechanism 1, and the sensor system 3 detects that the pipe 5 has reached the traction mechanism 1, and transmits a signal to the controller. The controller controls the traction mechanism 1 to start, and the traction mechanism 1 pulls the pipe 5 to move toward the drilling mechanism 2. When the pipe 5 moves to the drilling station, the sensor system 3 transmits a signal to the controller, and the controller controls the traction mechanism 1 to pause, and the drilling mechanism 2 to start, and drill the pipe 5. After one drilling is completed, the controller controls the traction mechanism 1 to restart, and the traction pipe 5 continues to move until the sensor system 3 detects that the pipe 5 has arrived at the next station, and the cycle is repeated until the drilling of the pipe 5 is completed.

[0032] like Figure 2 As shown, the sensor system 3 includes a feed start sensor 31, a drilling start sensor 32 and a feed end sensor 36. The feed start sensor 31 is arranged at the front end of the first mounting frame 6, the feed end sensor 36 is arranged at the rear end of the first mounting frame 6, and the drilling start sensor 32 is arranged on the first mounting frame 6. The direction opposite to the moving direction of the pipe 5 is the front, and the direction the same as the moving direction of the pipe 5 is the rear; when the feed start sensor 31 detects that the pipe 5 reaches the front end position of the traction mechanism 1, it transmits a signal to the controller, and the controller controls the pipe 5 to move toward the drilling mechanism 2; when the drilling start sensor 32 detects that the pipe 5 reaches a drilling station, the controller controls the drilling mechanism 2 to drill; when the feed end sensor 36 detects that the front end of the pipe 5 completely leaves the rear end of the traction mechanism 1, that is, when the pipe 5 is separated from the traction mechanism 1, the controller controls the traction mechanism 1 to stop working.

[0033] The working principle of the traction and hole-opening device for corrugated pipes of this embodiment is as follows: 1. When the pipe 5 is pulled and hole-opened, the pipe 5 is moved to the traction mechanism 1; the start feeding sensor 31 detects that the pipe 5 has reached the traction mechanism 1, and transmits a signal to the controller, and the controller controls the traction mechanism 1 to start, and the traction mechanism 1 pulls the pipe 5 to move to the drilling mechanism 2; 2. When the pipe 5 moves to the drilling station, the start drilling sensor 32 transmits a signal to the controller, and the controller controls the traction mechanism 1 to pause, and the drilling mechanism 2 to start, and the pipe 5 is drilled; 3. The drilling result at the position is After the bundle is tied, the controller controls the traction mechanism 1 to restart, and the traction pipe 5 continues to move until the start drilling sensor 32 detects that the pipe 5 has arrived at the next station. The controller controls the traction mechanism 1 to stop working, and the drilling mechanism 2 drills again; 4. Repeat steps 2 and 3 for a certain number of times until all the predetermined drilling positions are drilled, and the drilling mechanism 2 stops; 5. The pipe 5 is removed from the traction mechanism 1. When the end feeding sensor 36 located at the rear end of the first mounting bracket 6 detects that the pipe 5 has completely left the traction mechanism 1, the traction and hole opening equipment stops working; 6. Repeat steps 1 to 5.

[0034] Embodiment 2

[0035] This embodiment is the second embodiment of the present invention, and is similar to the first embodiment, except that it further includes a clamping mechanism 4 for clamping and positioning the corrugated pipe, the clamping mechanism 4 is mounted on the first mounting frame 6, the clamping mechanism 4 is connected to the controller, and the traction mechanism 1, the drilling mechanism 2 and the clamping mechanism 4 are arranged in sequence. When the start drilling sensor 32 detects that the pipe 5 arrives at the drilling station, the controller controls the clamping mechanism 4 to clamp the pipe 5 to prevent the pipe 5 from continuing to move due to inertia, resulting in inaccurate drilling position.

[0036] The sensor system 3 also includes a trough position sensor 34 for sensing the trough position of the pipe 5. The trough position sensor 34 is arranged on the drilling mechanism 2 and is connected to the controller. When the trough position sensor 34 detects that the trough of the pipe 5 reaches the drilling position of the drilling mechanism 2, it transmits a signal to the controller, the traction mechanism 1 stops working, the clamping mechanism 4 clamps the pipe 5, and the controller controls the drilling mechanism 2 to drill at the trough of the pipe 5; when the trough is not detected, the traction mechanism 1 continues to move until the trough is detected; thus, the automated drilling operation of the trough of the pipe 5 can be realized.

[0037] The clamping mechanism 4 includes two groups of clamping blocks 41 and a first driving device 42 for driving the two groups of clamping blocks 41 to move toward each other. The clamping blocks 41 are fixedly connected to the output end of the first driving device 42. The driving directions of the two groups of first driving devices 42 are opposite and perpendicular to the axis of the corrugated pipe. The controller is connected to the first driving device 42. When the pipe 5 reaches the drilling station, the two groups of first driving devices 42 respectively drive the two groups of clamping blocks 41 to move toward each other until the clamping blocks 41 clamp the pipe 5. In this embodiment, the first driving device 42 is a double-axis cylinder.

[0038] Two or more drilling mechanisms 2 are arranged on the first mounting frame 6, and each drilling mechanism 2 is arranged along the axial direction of the pipe 5. By providing two or more drilling mechanisms 2, holes can be drilled simultaneously at different positions in the axial direction of the pipe 5, thereby improving the drilling efficiency.

[0039] like Figure 2 As shown, the sensor system 3 further includes a drilling pause sensor 33, which is arranged on the first mounting bracket 6 and connected to the controller. The direction opposite to the moving direction of the pipe 5 is the front, and the direction consistent with the moving direction of the pipe 5 is the rear. When drilling a pipe 5 with an expanded opening, when the drilling pause sensor 33 detects that the expanded opening position of the pipe 5 reaches the drilling mechanism 2 at the front position, the controller controls the drilling mechanism 2 to suspend operation, and only the drilling mechanism 2 at the rear performs the drilling work.

[0040] In this embodiment, two front and rear drilling mechanisms 2 are provided, which are respectively referred to as the front station drilling mechanism 2 and the rear station drilling mechanism 2 .

[0041] like Figure 3 As shown, the drilling mechanism 2 includes a mounting plate 21 and a drilling assembly 23. The mounting plate 21 is mounted on the first mounting frame 6. The trough position sensor 34 is arranged on the mounting plate 21. The mounting plate 21 is provided with a through hole. The axis of the through hole coincides with the axis of the pipe 5. Two or more drilling assemblies 23 are arranged on one mounting plate 21. The drilling direction of the drilling assembly 23 coincides with the diameter direction of the pipe 5 to ensure that the hole position is flat and vertical.

[0042] like Figure 4As shown, the drilling assembly 23 includes a cylinder 22, a third mounting frame 231, a brushless motor 232 and a drill bit 233. The third mounting frame 231 is fixedly mounted on the first mounting frame 6. The third mounting frame 231 is an L-shaped plate structure. A linear guide rail 234 is provided on the third mounting frame 231. A slider 235 is slidably mounted on the linear guide rail 234. The brushless motor 232 is fixedly mounted on the slider 235. The output end of the cylinder 22 passes through the side of the third mounting frame 231 that is perpendicular to the mounting plate 21, and is fixedly connected to the brushless motor 232. The output end of the brushless motor 232 is fixedly connected to the drill bit 233. When the drilling assembly 23 is working, the cylinder 22 drives the brushless motor 232 to move along the linear guide 234 with the slider 235 toward the pipe 5. When the drill bit 233 reaches the outer wall of the pipe 5, the brushless motor 232 drives the drill bit 233 to rotate, and the cylinder 22 continues to drive the brushless motor 232 and the drill bit 233 to move toward the axis of the pipe 5 to perform a hole opening operation on the pipe 5.

[0043] like Figure 1 and Figure 3 As shown, the apparatus further includes an adjustment mechanism 24 for adjusting the horizontal position of the drilling mechanism 2, the adjustment mechanism 24 is mounted on the first mounting frame 6, and the adjustment mechanism 24 is connected to the drilling mechanism 2. When drilling holes in different pipes 5, the distances of the holes along the axis of the pipe 5 may be different. For example, the different spacings between the troughs result in different hole spacings. The adjustment mechanism 24 is used to adjust the horizontal position of the drilling mechanism 2, change the distance between the drilling mechanisms 2, and adjust the drilling spacing, so that when one drilling mechanism 2 reaches the drilling position, the other drilling mechanisms 2 also reach the correct drilling position, thereby increasing the applicability of the apparatus to different pipes 5.

[0044] In this embodiment, the adjustment mechanism 24 is connected to the mounting plate 21. Figure 5 As shown, the adjustment mechanism 24 includes a screw rod 241, a screw rod 241 support, a third driving device 243 for driving the screw rod 241 to rotate, and a guide mechanism 244 for limiting the horizontal movement of the drilling mechanism 2. The screw rod 241 support is fixed on the first mounting frame 6, the screw rod 241 is rotatably connected to the screw rod 241 support, a screw hole matching the screw rod 241 is provided on the drilling mechanism 2, the screw rod 241 passes through the screw hole, and the guide mechanism 244 is fixedly arranged on the mounting frame, and the guide mechanism 244 is connected to the drilling mechanism 2. When the adjustment mechanism 24 is working, the third driving device 243 drives the screw rod 241 to rotate. Since the guide mechanism 244 limits the movement direction of the drilling mechanism 2, the drilling mechanism 2 cannot rotate with the screw rod 241, and the screw rod 241 drives the drilling mechanism 2 to move in the horizontal direction through the screw hole, thereby adjusting the position of the drilling mechanism 2.

[0045] The working principle of the traction and hole-opening device applied to the corrugated pipe of the present embodiment is as follows: 1. According to the specifications of the pipe 5, the distance between the drilling mechanisms 2 is adjusted by the adjustment mechanism 24; 1. The traction mechanism 1 pulls the pipe 5 to move toward the drilling mechanism 2, and the drilling sensor 32 starts to detect that the pipe 5 has reached the drilling station, and transmits a signal to the controller, and the controller controls the traction mechanism 1 to stop working; 2. The controller controls the two groups of first driving devices 42 of the clamping mechanism 4 to drive the two groups of clamping blocks 41 to move toward each other, until the clamping blocks 41 clamp the pipe 5 in place; 3. The clamping mechanism 4 is released, and the traction mechanism 1 continues to move the pipe 5. When the trough position sensor 34 detects that the trough of the pipe 5 reaches between the drilling components 23, it transmits a signal to the controller, the traction mechanism 1 stops working, and the clamping mechanism 4 clamps the pipe 5; 4. The controller controls the cylinder 22 to drive the brushless motor 232 to move with the slider 235 Move along the linear guide rail 234 toward the pipe 5. When the drill bit 233 reaches the bottom of the trough of the pipe 5, the brushless motor 232 drives the drill bit 233 to rotate, and the cylinder 22 continues to drive the brushless motor 232 and the drill bit 233 to move toward the axis of the pipe 5 to drill the pipe 5; 5. After the drilling of the trough position is completed, the traction mechanism 1 continues to pull the pipe 5; 6. Repeat steps 3 to 5 for a certain number of times. Most of the troughs have been drilled. The drilling pause sensor 33 detects that the expansion of the pipe 5 is about to reach the front station drilling mechanism 2, and transmits a signal to the controller. The front station drilling mechanism 2 stops working to avoid the expansion of the pipe 5. Only the rear station drilling mechanism 2 drills the trough near the expansion; 7. When the drilling pause sensor 33 detects that the expansion of the pipe 5 reaches the rear station drilling mechanism 2, both drilling mechanisms 2 stop working and the drilling work is completed; 8. Repeat steps 1 to 7.

[0046] Embodiment 3

[0047] This embodiment is the third embodiment of the present invention, and this embodiment is similar to the second embodiment, except that the traction mechanism 1 includes two or more traction devices 12 and a second driving device 11 for driving the traction devices 12 to approach or move away from each other, the second driving device 11 is mounted on the first mounting frame 6, the traction device 12 is connected to the second driving device 11, the traction device 12 clamps the pipe 5, and the driving directions of each group of traction devices 12 are the same. When pulling the pipe 5, two or more pulling devices 12 are placed in a straight line, and the pipe 5 is moved between the pulling mechanisms 1. The second driving devices 11 in the two or more pulling mechanisms 1 drive the pulling devices 12 to clamp the pipe 5, and the pulling devices 12 drive the pipe 5 to move. When the expansion position of the pipe 5 moves to the traction device 12 of a traction mechanism 1, the second driving device 11 of the traction mechanism 1 drives the traction devices 12 to separate from each other, and the pipe 5 is loosened to avoid the expansion position of the pipe 5. The traction devices 12 of other traction mechanisms 1 continue to pull the pipe 5, thereby achieving continuous clamping and pulling of the pipe 5 while avoiding the expansion of the pipe 5, thereby improving work efficiency.

[0048] like Figure 2 As shown, the sensor system 3 also includes a flaring sensor 35 for sensing the flaring position of the pipe 5. The flaring sensor 35 is arranged on the first mounting bracket 6. The flaring sensor 35 is connected to the controller, and the controller is connected to the second driving device 11. When the flaring sensor 35 senses that the flaring of the pipe 5 reaches the front of the traction mechanism 1, it transmits a signal to the controller. The controller controls the driving mechanism to drive the traction mechanism 1 away from each other to avoid the flaring position of the pipe 5, thereby realizing automatic flaring of the pipe 5 to avoid flaring, saving labor and improving work efficiency.

[0049] like Figure 1 , Figure 6 and Figure 7As shown, the traction device 12 includes a first traction device 121, a second traction device 122 and a third traction device 123, the second drive device 11 includes a first telescopic mechanism 111, a second telescopic mechanism 112 and a third telescopic mechanism 113, the first telescopic mechanism 111, the second telescopic mechanism 112 and the third telescopic mechanism 113 are installed on the first mounting frame 6, the first traction device 121, the second traction device 122 and the third traction device 123 are respectively connected to the output ends of the first telescopic mechanism 111, the second telescopic mechanism 112 and the third telescopic mechanism 113, and the first traction device 121, the second traction device 122 and the third traction device 123 are centrally symmetrically distributed. Move the pipe 5 between the three groups of traction devices 12, and adjust the telescopic amounts of the first telescopic mechanism 111, the second telescopic mechanism 112 and the third telescopic mechanism 113 until the first traction device 121, the second traction device 122 and the third traction device 123 clamp the pipe 5. Because the three groups of traction devices 12 are axially symmetrically distributed, the axis of the pipe 5 coincides with the axis of symmetry of the traction device 12, so that the force on the pipe 5 is uniform and the traction process is more stable.

[0050] In this embodiment, two traction mechanisms 1 are provided, which are respectively denoted as a front traction mechanism 1 and a rear traction mechanism 1 , and the drilling mechanism 2 is located between the front traction mechanism 1 and the rear traction mechanism 1 .

[0051] The working principle of the traction and hole-opening device applied to the corrugated pipe of the present embodiment is as follows: 1. When the pipe 5 is pulled and hole-opened, the pipe 5 is moved to the vicinity of the symmetric axis of the first traction device 121, the second traction device 122 and the third traction device 123 of the front traction mechanism 1; 2. The feed start sensor 31 detects that the pipe 5 has reached the front traction mechanism 1, and transmits a signal to the controller. The controller controls the traction mechanism 1 located at the front end of the traction and hole-opening device to start, and the first telescopic mechanism 111, the second telescopic mechanism 112 and the third telescopic mechanism 113 in the traction mechanism 1 respectively drive the first traction device 121, the second telescopic mechanism 112 and the third telescopic mechanism 113 to move ... The second traction device 122 and the third traction device 123 bring the three traction devices 12 closer to each other and clamp the pipe 5; 3. The third motor drives the driving wheel to rotate, driving the second chain and the driven wheel to rotate, and the second chain drives the anti-sliding block 235 to move along the second chain, and the anti-sliding block 235 presses the pipe 5, and the anti-sliding block 235 drives the pipe 5 to move toward the drilling mechanism 2 through friction; 4. When the trough position sensor 34 detects that the trough of the pipe 5 reaches between the drilling components 23, it transmits a signal to the controller, the traction mechanism 1 stops working, the clamping mechanism 4 clamps the pipe 5, and the drilling mechanism 2 drills the pipe 5; 5. After the drilling of the hole at this position is completed, the controller controls the traction mechanism 1 to restart, and the traction pipe 5 continues to move; 6. Repeat steps 4 and 5 for a certain number of times. When the expansion sensor 35 senses that the expansion of the pipe 5 reaches the front of the front traction device 12, it transmits a signal to the controller, and the controller controls the first telescopic mechanism 111, the second telescopic mechanism 112 and the third telescopic mechanism 113 to drive the first traction device 121, the second traction device 122 and the third traction device 123 to move away from each other, avoiding the expansion position of the empty pipe 5, and realizing automatic expansion of the empty pipe 5. The rear traction device 12 continues to pull the pipe 5, thereby avoiding the expansion position of the empty pipe 5. While the pipe 5 is expanded, the pipe 5 is continuously clamped and pulled; 7. Steps 4 and 5 are repeated. When the drilling pause sensor 33 detects that the pipe 5 is expanded, the drilling mechanism 2 stops working completely and the drilling work is completed; 8. When the expansion sensor 35 on the rear traction mechanism 1 detects that the expansion of the pipe 5 reaches the rear traction mechanism 1, the rear traction mechanism 1 avoids the expansion of the pipe 5 and releases the pipe 5; 9. The pipe 5 is removed from the rear traction mechanism 1. When the feeding end sensor 36 detects that the pipe 5 has completely left the traction mechanism 1, the traction mechanism 1 stops working and the traction and hole-opening equipment stops working completely; 10. Steps 1 to 9 are repeated.
