At the same time, at least one of the first mounting member and the second mounting member has a horizontal adjustment function to adjust the relative distance between the pipe bracket 2 and the punching mechanism. When the pipe bracket 2 and the punching mechanism are close to each other, the relative distance between the two is reduced, and the punching mechanism can carry out and complete the row punching operation of the pipes 3 to be punched on the pipe bracket 2. Conversely, when the punching is completed, the first mounting member and / or the second mounting member uses the horizontal adjustment function to drive the pipe bracket 2 and the punching mechanism away from each other, and the relative distance between the two is increased, and the pipes 3 to be punched on the pipe bracket 2 are evacuated from the punching range of the punching mechanism.

The translation assembly 6 is arranged on the lifting plate 51, and the pipe bracket 2 is connected to the translation assembly 6. Generally, both ends of the lifting plate 51 are connected to the first step surface 11 through an adjustment mechanism composed of the lead screw 52, ​​the flange nut 53 and the thin nut 54. During the lifting and lowering adjustment, the lifting plate 51 remains in a horizontal state and rises and falls.

[0038] In this embodiment, the translation assembly 6 includes a cylinder 61, a guide rail 62 and a slider 63. The guide rail 62 is horizontally arranged on the lifting plate 51 and extends in a direction perpendicular to the pipe 3 to be punched. The slider 63 slides with the guide rail 62. The pipe bracket 2 is arranged above the slider 63 and is fastened to the slider 63 by bolts or nuts. The cylinder 61 is horizontally arranged on the lifting plate 51 and is connected to the pipe bracket 2.

The lifting plate 51 is generally provided with a protruding bracket, and the cylinder barrel of the cylinder 61 can be fixed to the protruding bracket by clamping, threaded connection or bolt fixing.

[0039] In this embodiment, Figure 1 As shown, the pipe bracket 2 is U-shaped as a whole, the interior of the U is used to place the pipe 3 to be punched, and the two sides of the U are used to prevent the pipe 3 to be punched from rolling down from the two sides. Generally, the distance between the two sides of the U is greater than the diameter of the pipe 3 to be punched, which is convenient for taking and placing the pipe 3 to be punched from the pipe bracket 2, and also convenient for the pipe 3 to be punched to rotate and adjust inside the U.

[0040] In this embodiment, the cylinder 61 is preferably equipped with a foot switch, which is used to control the extension and retraction of the cylinder 61. Generally, the foot switch is preferably set on the ground, and the operator can step on it to control the horizontal movement process of the pipe bracket 2 without using hands, making the punching process faster and more efficient.

[0041] In this embodiment, the frame 1 is preferably a step frame, the lifting assembly 5 is arranged on the first step surface 11 of the step frame, the second mounting member is a fastener, which has neither lifting and lowering adjustment function nor horizontal adjustment function, and the punching mechanism is fixedly mounted on the second step surface 12 of the step frame through the fastener, and the second step surface 12 is higher than the first step surface 11. The aforementioned fastener can be a structure such as a bolt or a screw, and the relative position of the punching mechanism and the frame 1 is fixed and arranged on the high step surface of the frame 1.

[0042] In this embodiment, according to the different numbers of steps of different step racks, the second step surface 12 is at least one step higher than the first step surface 11. For example, the step rack is a two-step step rack, the second step surface 12 and the first step surface 11 are respectively the high-step surface and the low-step surface of the two-step step rack, and the second step surface 12 is one step higher than the first step surface 11; for another example, the step rack is a three-step step rack, the second step surface 12 and the first step surface 11 can be arranged at intervals or adjacent to each other. When the second step surface 12 and the first step surface 11 are arranged at intervals, the second step surface 12 is two steps higher than the first step surface 11. When the second step surface 12 and the first step surface 11 are arranged adjacent to each other, the second step surface 12 is one step higher than the first step surface 11. At this time, the second step surface 12 and the first step surface 11 can be respectively located at the high-step surface and the middle-step surface of the three-step step rack, or respectively located at the middle-step surface and the low-step surface of the three-step step rack. Considering the compactness of the structure, the manufacturing cost and the practicality, the ladder frame used in the rack 1 of this embodiment is preferably a two-step ladder frame, such as Figure 1 and Figure 3 shown.

[0043] In this embodiment, it is preferred that any of the punching units 4 is a drilling machine, such as Figure 1 As shown, the drilling machine includes a rotary drive, a drill chuck 42, a bearing seat 43 and a punching drill bit 44. The bearing seat 43 is fixedly mounted on the second step surface 12 by the aforementioned fasteners. The two ends of the drill chuck 42 are respectively rotatably connected to a bearing seat 43. The head end of the drill chuck 42 is connected to the punching drill bit 44. The rear end of the drill chuck 42 is connected to the rotary drive, and the rotary drive is used to drive the drill chuck 42 and the punching drill bit 44 to rotate. Any drilling machine can be disassembled and installed on the second step surface 12 as an independent unit. The arrangement interval of the drilling machine on the second step surface 12 corresponds to the hole spacing of each row of holes on the pipe 3 to be punched. The installation position of the drilling machine on the second step surface 12 can be adjusted according to the different hole spacing of each row of holes on the pipe 3 to be punched. In order to facilitate the adjustment of the spacing of the drilling rig on the second step surface 12, it is preferred to arrange a plurality of mounting holes on the second step surface 12 to ensure that the drilling rig can be installed at any position of the second step surface 12, thereby improving the flexibility of adjusting the installation position of the drilling rig, thereby meeting the different drilling requirements of different pipes (mainly reflected in meeting the different hole spacings along the axial direction of the pipe 3 to be drilled).

[0044] In this embodiment, the above-mentioned rotation drive includes a motor and a transmission wheel 41, the transmission wheel 41 is connected to the end of the drill chuck 42, and the output end of the motor is connected to the transmission wheel 41 through a transmission belt or chain. As a preferred solution, the transmission wheel 41 of this embodiment adopts a pulley, which is fixed to the drill chuck 42 by a key connection, and the output end of the motor is connected to the transmission wheel 41 through a transmission belt, so that the drill chuck 42 is driven by the motor to rotate, and then the punching drill 44 is driven to rotate. When the pipe 3 to be punched approaches and contacts the punching drill 44, the corresponding position of the pipe 3 to be punched can be punched by the punching drill 44.

[0045] The following takes the double-walled corrugated pipe for tunnel drainage as an example to describe the use steps and use principle of the double-walled corrugated pipe drilling device 100 for tunnel drainage in this embodiment. The use steps of the double-walled corrugated pipe drilling device 100 for tunnel drainage are as follows:

[0046] 1. By adjusting the flange nut 53 and the lead screw 52 of the lifting assembly 5, the lifting plate 51 can be adjusted to move up and down relative to the first step surface 11, so that the center of the pipe 3 to be punched on the pipe bracket 2 is aligned with the drilling drill 44 on each drilling rig.

[0047] Second, the motor is started by pressing the motor start button, the motor drives the transmission wheel 41 to rotate, the transmission wheel 41 drives the drill chuck 42 to rotate, and then drives the drilling drill bit 44 to rotate at a certain speed.

[0048] 3. Step on the foot switch of the air cylinder 61 to control the extension of the air cylinder rod of the air cylinder 61, push the pipe bracket 2 close to the drilling bit 44, and push the pipe 3 to be drilled to the drilling bit 44, so as to complete the single-row drilling. In this process, the pipe bracket 2 can be provided with a corresponding pipe fixing structure or the pipe can be supported manually to keep the pipe 3 to be drilled relatively still with the pipe bracket 2.

[0049] Fourth, release the foot switch of the cylinder 61, and the cylinder rod of the cylinder 61 automatically retracts, driving the pipe bracket 2 and the pipe to be punched 3 thereon away from the punching drill 44 and returning to the original position. In this process, the pipe to be punched 3 and the pipe bracket 2 can be kept relatively still by configuring a corresponding pipe fixing structure on the pipe bracket 2 or manually supporting the pipe.

[0050] Fifth, rotate the pipe 3 to be punched on the pipe bracket 2 by 90°, repeat the third and fourth processes, then rotate the pipe 3 to be punched by 180°, and repeat the third and fourth processes, thus completing all the punching processes of the pipe 3 to be punched. The punching range is within the upper half section of the pipe 3 to be punched, with a total of three rows of holes, and the spacing between the holes in any two rows of holes is the same.

[0051] It can be seen that the double-wall corrugated pipe punching equipment 100 for tunnel drainage has a novel and reasonable structure. Since the intervals of the pre-assembled drilling rigs are fixed, the axial spacing of the holes drilled on the pipe is fixed. Based on this, the pipe bracket 2 is driven close to and away from the punching drill 44 once to punch a row of holes on the surface of the pipe, and then rotated 90° to punch another row. By doing so, another row can be punched to complete the punching of the upper half section of the pipe, achieving the purpose of fast drilling and accurate hole spacing. At the same time, it has the advantages of high efficiency and low cost, and solves the problems of slow manual drilling speed and inaccurate spacing. It is suitable for drilling plastic pipes of different diameters (from 50mm to 315mm in diameter).

[0052] The above-mentioned double-wall corrugated pipe drilling equipment 100 for tunnel drainage can not only be used for the drilling operation of double-wall corrugated pipes for tunnel drainage, but can also be used for other pipes for tunnel drainage or other pipes in non-tunnel drainage fields.
