Description

Technical Field

[0001] The present invention relates to the technical field of hole opening of permeable pipes, and specifically to a numerical control hole opening device for hard permeable pipes. Background Art

[0002] Hard permeable pipes are mainly applied to large-scale underground water drainage projects such as railway construction, highway construction, and airport runways. Two-thirds of the upper part of the hard permeable pipe is provided with small holes, and one-third of the lower part is without holes, which can prevent secondary leakage of groundwater and quickly drain away the groundwater.

[0003] At present, the hole opening operation of hard permeable pipes is mainly carried out outside the pipe, but there are many drawbacks in the hole drilling operation outside the pipe. Affected by the interference of the pipe body curve, there are certain differences in the hole spacing of the holes opened on the pipe wall. Improper hole opening will cause the water permeability effect to decline. At the same time, after opening holes from the outside of the pipe to the inside, the mechanical strength of the outer wall of the permeable pipe is likely to be damaged to a certain extent due to mechanical pressure, and in severe cases, the compressive strength of the outer wall of the permeable pipe will be reduced.

As multiple groups of pipe wall drilling mechanisms are compressed and expand outward at equal intervals, the evenly distributed drill bits can open holes in the water permeable pipe from the inside to the outside. The structure of the inner wall of the water permeable pipe with holes can effectively enhance the compressive strength of the outer pipe wall, thereby avoiding excessive differences in the hole distances of the pipe body openings.

[0018] 3. By setting the drill bit as a frustum-shaped structure and opening coarsely ground grooves on the outer wall of the drill bit in the present invention, after the drill bit is compressed and continuously presses the water permeable pipe body from the inside to the outside, the efficiency of opening holes in the water permeable pipe can be accelerated.

[0021] To make the purpose, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with the specific implementation manners and with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0022] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0023] The following describes a numerical control hole-opening device for a rigid water-permeable pipe provided by some embodiments of the present invention with reference to the accompanying drawings. Embodiment 1:

[0024] Combined with Figures 1 to 10As shown in the figure, a numerical control hole - opening device for a rigid water - permeable pipe provided by the present invention includes a water - permeable pipe body 100, a pipe - wall assisting mechanism 200 arranged inside the water - permeable pipe body 100, a control mechanism 300 arranged inside the pipe - wall assisting mechanism 200, an inner - supporting mechanism 400 arranged on the pipe - wall assisting mechanism 200, and multiple groups of pipe - wall drilling mechanisms 500 arranged inside the inner - supporting mechanism 400. The pipe - wall assisting mechanism 200 is used to improve the stability of the inner - supporting mechanism 400 and multiple groups of pipe - wall drilling mechanisms 500. The control mechanism 300 is used to supply energy to multiple groups of pipe - wall drilling mechanisms 500. The inner - supporting mechanism 400 is used to provide effective support for multiple groups of pipe - wall drilling mechanisms 500. When multiple groups of pipe - wall drilling mechanisms 500 are pressed to expand outward or contract, they can perform equal - depth drilling operations on the water - permeable pipe body 100.

[0025] The pipe - wall assisting mechanism 200 includes a base 210 and two pipe - wall protection plates 2501, and the two pipe - wall protection plates 2501 are attached to the inner wall of the water - permeable pipe body 100 with the base 210 as the center. The control mechanism 300 includes a machine base 310 arranged inside the base 210, a linkage shaft 340 and a first motor 320 arranged inside the machine base 310, a driving pulley 3201 installed on the first motor 320, and a transmission pulley 3401 installed on the linkage shaft 340, and a transmission belt 350 is connected in transmission between the driving pulley 3201 and the transmission pulley 3401. The inner - supporting mechanism 400 includes a cushion plate 410 arranged outside the base 210, multiple load - bearing plates 420 arranged outside the cushion plate 410, a ring cushion 430 arranged at the other end of the load - bearing plate 420, multiple wing plates 4301 arranged on the ring cushion 430, multiple first bolts 4302 arranged inside the ring cushion 430, and multiple fixing plates 4303 fixedly installed on the inner wall of the ring cushion 430. The fixing plate 4303 is used to provide effective clamping for the vertical shaft 5201. The pipe - wall drilling mechanism 500 includes an outer cushion 510 arranged outside the wing plate 4301, a housing 5102 arranged on the outer cushion 510, a drill bit 520 movably installed inside the housing 5102, a vertical shaft 5201 movably installed inside the drill bit 520, and a gear 550 installed at the bottom end of the vertical shaft 5201.

[0026] First, compress the two pipe - wall protection plates 2501, then horizontally insert the pipe - wall assisting mechanism 200 and multiple groups of pipe - wall drilling mechanisms 500 into the inner cavity of the water - permeable pipe body 100. As the two pipe - wall protection plates 2501 are pressurized, two groups of traction plates 230 pulled by two tension springs 2302 will cooperate with four sliders 240 to expand the two pipe - wall protection plates 2501 outward, and the expanded two pipe - wall protection plates 2501 will fit the inner wall of the water - permeable pipe body 100. After the cable 220 is towed to drive the pipe wall assisting mechanism 200 to move horizontally at a constant speed to a specified position inside the water permeable pipe body 100, then the first motor 320 is operated. At this time, the driving pulley 3201 will be driven by the first motor 320. Then, after the transmission belt 350 is driven, it will drive the transmission belt pulley 3401 and the linkage shaft 340 to rotate at a constant speed. The deflection gears at the inner ends of the linkage shafts 340 will simultaneously drive a plurality of gears 550, and the vertical shafts 5201 installed inside the gears 550 will drive the drill bits 520. Finally, the uniformly distributed multiple drill bits 520 will maintain the same rotation speed; Then the second motor 330 is operated. As the transmission shaft inside the second motor 330 drives the progressive lead screw 3301 to rotate, the support plate 3403 and the sliding seat 3402 will be pressed to push and extend progressively. Finally, multiple sets of inclined frames 3404 movably installed on the sliding seat 3402 will push multiple sets of support plates 5401 to expand outward. The multiple compressed drill bits 520 can maintain the same spacing and approach the inner wall of the water permeable pipe body 100. Finally, the water permeable pipe body 100 can be drilled from the inside to the outside. After the holes are formed, the drill bits 520 can polish the hole walls. Embodiment 2:

[0027] Combined with Figure 1 To Tao Figure 4 As shown, on the basis of Embodiment 1, the pipe wall assisting mechanism 200 further includes four support plates 2102 installed on the base 210, and two support plates 2102 form a group; A clamping member 2103 is movably installed inside the support plate 2102, a first spring 2104 arranged inside the support plate 2102 and pressing on the clamping member 2103, and two stability enhancing rollers 2105 movably installed inside two groups of support plates 2102; A cable 220 is installed inside the base 210, and the cable 220 is located at the central position of the inner cavity of the water permeable pipe body 100; An end plate 2101 is installed in the middle of the base 210.

[0028] Preferably, the two groups of support plates 2102 and the four first springs 2104 can enhance the constant pressure support for the two stability enhancing rollers 2105. The clamping member 2103 pressed by the first spring 2104 can improve the rotation stability of the stability enhancing rollers 2105. The two stability enhancing rollers 2105 and the two pipe wall protection plates 2501 can improve the stability of the fixed inner support mechanism 400, ensuring that the inner support mechanism 400 and multiple groups of pipe wall drilling mechanisms 500 are always located at the central position of the inner cavity of the water permeable pipe body 100.

[0029] The pipe wall assisting mechanism 200 further includes two groups of traction plates 230 movably installed on the end plate 2101, and the number of each group of traction plates 230 is two; Two traction plates 230 are stacked on the top and bottom of the end plate 2101 in a triangular structure, with a foot pad 2301 movably installed inside the traction plate 230 and a tension spring 2302 connected to the foot pad 2301; One end of the traction plate 230 away from the end plate 2101 is installed with a support rod 2303, and a slider 240 is movably installed outside the support rod 2303; A slide rail 250 is installed on the inner side of the pipe wall guard plate 2501, and the slider 240 is movably installed in the slide rail 250; Two stability-enhancing rollers 2105 and two pipe wall guard plates 2501 cooperate to form a cross-shaped structure, which is used to enhance the stability of the horizontally placed inner support mechanism 400 and multiple groups of pipe wall drilling mechanisms 500; The outer wall of the pipe wall guard plate 2501 is provided with a smooth ceramic sticker layer, which is used to reduce the frictional resistance to the inner wall of the water permeable pipe body 100; The stability-enhancing roller 2105 is composed of an end shaft, a hub and a tread, and grooves for increasing the frictional resistance are opened on the outer side of the tread.

[0030] Preferably, two stability-enhancing rollers 2105 and two pipe wall guard plates 2501 cooperate to form a cross-shaped structure. After the two pipe wall guard plates 2501 are expanded to the maximum state, the two stability-enhancing rollers 2105 will also be compressed and expand outwards. Finally, the two stability-enhancing rollers 2105 and two pipe wall guard plates 2501 distributed in a cross-shaped structure can enhance the pressure-bearing protection of the inner wall of the water permeable pipe body 100, so as to ensure that the horizontally placed inner support mechanism 400 provides a stable drilling platform for multiple groups of pipe wall drilling mechanisms 500 evenly distributed. Embodiment 3:

[0031] Combined with Figures 5 to 10 As shown in the above embodiment, the control mechanism 300 further includes a second motor 330 installed inside the machine base 310, a positioning plate 3101 installed in the machine base 310, a progressive lead screw 3301 movably installed inside the positioning plate 3101, and the transmission shaft in the second motor 330 is connected to the progressive lead screw 3301; An oval hole groove is opened inside the positioning plate 3101, and the linkage shaft 340 is adapted to penetrate into the oval hole groove; A sliding seat 3402 is arranged outside the linkage shaft 340, a support plate 3403 installed on the sliding seat 3402 and multiple groups of inclined frames 3404 movably installed on the sliding seat 3402, and the inclined frames 3404 are connected to the inner support 540 through two support plates 5401.

[0032] The progressive lead screw 3301 is composed of a lengthened lead screw and an I-shaped bushing, and the I-shaped bushing is movably installed inside the positioning plate 3101; The pipe wall drilling mechanism 500 further includes a circular pad 5103 installed on the inner wall of the outer shell 5102, a second spring 530 disposed outside the drill bit 520, and two studs 5101 installed on the outer pad 510; A jack is provided inside the drill bit 520, and a vertical shaft 5201 is arranged in the jack, an inner bracket 540 disposed outside the vertical shaft 5201, and two support plates 5401 arranged inside the inner bracket 540.

[0033] Preferably, four positioning studs are symmetrically distributed on both sides of the machine base 310, and nuts are arranged outside the positioning studs, and the nuts are used to fix the base 210. Heat dissipation notches are provided in the machine covers at the top and bottom of the machine base 310; Among them, the linkage shaft 340 is installed in a horizontal hole inside the machine base 310 through a bearing. Lubricating oil is coated inside the sliding seat 3402, and multiple groups of inclined frames 3404 are arranged outside the sliding seat 3402 in a structure similar to umbrella ribs; In addition, the wing plate 4301 is fixed to the outside of the outer pad 510 through the stud 5101; Specifically, when the pressure on the support plate 5401 is lost, under the extrusion of the second spring 530, the drill bit 520 will quickly contract along the inner cavities of the two outer shells 5102. Finally, the drill bit 520 will extend along the outside of the vertical shaft 5201. After the ring pad 430 drives multiple gears 550 and the vertical shaft 5201, the uniformly distributed multiple drill bits 520 can drill holes with equal depth on the inner wall of the water permeable pipe body 100.

[0034] The working principle and usage process of the present invention: First, place the water permeable pipe body 100 to be drilled horizontally, then press the two pipe wall protection plates 2501 until the two pipe wall protection plates 2501 contract with the base 210 as the center. Then, pre-install the device inside the water permeable pipe body 100 and move it horizontally starting from one end of the water permeable pipe body 100; As the cable 220 is pulled and the first motor 320 is started, at this time, the first motor 320 will drive the driving pulley 3201, and the driving pulley 3201 will drive the transmission belt 350. Finally, the transmission belt 350 will drive the transmission belt pulley 3401 and the linkage shaft 340 to rotate. The deflection gear at the outer end of the linkage shaft 340 will drive multiple gears 550, and the vertical shaft 5201 installed in the gear 550 will drive the drill bit 520. At this time, the multiple drill bits 520 evenly distributed in a circle will rotate at the same speed; With the reverse rotation of the second motor 330, its internal transmission shaft will drive the progressive lead screw 3301 to rotate at a constant speed, and the support plate 3403 and the slide block 3402 will extend outward along the linkage shaft 340. Eventually, the slide block 3402 will exert pressure on multiple evenly distributed inclined frames 3404, and the multiple inclined frames 3404 under pressure will push multiple support plates 5401 to extend outward. At the same time, the support plates 5401 will push the drill bit 520 to extend outward, and the drill bit 520 extending outward will drill the inner wall of the water permeable pipe body 100. The holes drilled in the inner wall of the water permeable pipe body 100 are in a conical structure, and the hole structure with a wider inner width and a narrower outer width can effectively enhance the bearing capacity of the outer wall of the water permeable pipe body 100; After the designated part of the inner wall of the water permeable pipe body 100 is drilled, control the second motor 330 to rotate forward again. The driven progressive lead screw 3301 will boost the support plate 3403 and the slide block 3402 to approach the base 210. The multiple inclined frames 3404 pulled by the slide block 3402 will pull multiple support plates 5401 to contract towards the inner cavity of the housing 5102. With the reset thrust of the second spring 530, the drill bit 520 will accelerate and contract into the inner cavity of the housing 5102. Then, use an external traction device to drive the cable 220 to stretch around the water permeable pipe body 100. The two pipe wall protection plates 2501 and the two stability enhancing rollers 2105 will closely adhere to the inner wall of the water permeable pipe body 100 and move horizontally. At this time, the distances between the contracted multiple drill bits 520 and the inner wall of the water permeable pipe body 100 are the same. Therefore, as the device moves to other parts inside the water permeable pipe body 100, the multiple drill bits 520 that are externally supported can drill holes with a fixed hole depth on the inner wall of the water permeable pipe body 100.

[0035] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
