DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] Embodiment 1: This embodiment provides a drainage hole opening device for house waterproofing modification. Figure 1-Figure 3 As shown, it includes a mounting frame 1, on which an adjusting frame 3 is installed, and the adjusting frame 3 includes a fixed part and a movable part. The movable part is provided with three functional areas of hole opening, refinement and coarsening. The hole opening area is provided with a hole opening component 4, the refinement area is provided with a refinement component 5, and the coarsening area is provided with a coarsening component 6. The movable part includes a rotating frame, and the movable frame is provided with a driving unit, and the driving unit is used to drive the hole opening component 4, the refinement component 5, and the coarsening component 6 to operate; each functional area on the movable frame is installed with a cylinder 301, and the hole opening component 4, the refinement component 5, and the coarsening component 6 are respectively connected to the corresponding cylinder 301 in transmission; the cylinder 301 is used to control the transmission relationship between the driving unit and the hole opening component 4, the refinement component 5, and the coarsening component 6.

[0030] When it is necessary to perform a hole drilling operation, firstly, the hole drilling component 4 is used to be close to the building body 2, and the cylinder 301 in the hole drilling area is extended, so that the driving unit and the hole drilling component 4 are connected by power, and then the driving unit is started to drive the hole drilling component 4 to perform the hole drilling operation, and the cylinder 301 is continuously extended, so that the hole drilling component 4 continues to dig; after the hole drilling is completed, the hole drilling component 4 is retracted, and the refinement component 5 or the coarsening component 6 is switched according to actual needs to further process the hole drilled by the hole drilling component 4; when the drainage hole needs to be directly inserted into the drainage pipe, in order to prevent the rough inner wall of the drainage hole from damaging the pipe, the refinement component 5 can be used to grind the inner wall of the drainage hole to protect the drainage pipe inserted later; when the drainage pipe is inserted into the drainage hole and the hole needs to be sealed with materials such as foam glue or polyurethane foam, the coarsening component 6 can be used to further coarsen the inner wall of the drainage hole to prevent the foam glue and other materials from being separated from the drainage hole when the drainage pipe is displaced, thereby increasing the adhesion of the foam glue.

[0031] Embodiment 2: This embodiment further expands the adjustment frame 3, the hole opening component 4, the refinement component 5, and the coarsening component 6 on the basis of the above embodiment. Figure 5-Figure 6As shown, the driving unit includes a main motor 307 mounted on a movable frame, a driving gear shaft 310 is mounted on the output end of the main motor 307, and the plurality of functional areas are distributed in a circular array with the main motor 307 as the center.

[0032] like Figure 8 As shown, the hole-opening component 4 includes a hole-opening shaft 405, on which a first gear 401 and a protective cover 402 are installed, and the first gear 401 is meshed with the driving gear shaft 310 to realize power transmission; a second spring 406 is arranged between the protective cover 402 and the first gear 401, and a plurality of guide plates 407 are installed at the end of the hole-opening shaft 405, and hole-opening teeth 408 are installed on the guide plates 407; the hole-opening shaft 405 is transmission-connected to the cylinder 301 in the hole-opening area.

[0033] When the hole punching assembly 4 is required to punch a hole, the cylinder 301 extends, and the first gear 401 begins to mesh with the driving gear shaft 310. After the main motor 307 is started, the driving gear shaft 310 drives the first gear 401 to rotate, and the first gear 401 drives the hole punching shaft 405 to rotate. At this time, the protective cover 402 is pressed on the building body 2 under the action of the second spring 406. Since the protective cover 402 is only sleeved on the hole punching shaft 405, the protective cover 402 will not rotate, and the guide plate 407 is opened. The hole shaft 405 drives the rotation, and the hole-making teeth 408 begin to break the wall and drill a hole. The generated dust is blocked by the protective cover 402. As the cylinder 301 continues to extend, the excavation depth of the hole-making teeth 408 becomes deeper and deeper, and the compression amount of the second spring 406 becomes larger and larger. When the drilling is completed, the cylinder 301 retracts, and the hole-making shaft 405 retracts synchronously. The first gear 401 disengages from the driving gear shaft 310, and the protective cover 402 detaches from the building 2. At this time, the dust is scattered and personnel can collect it.

[0034] like Figure 7 As shown, the refinement component 5 includes a grinding shaft 505, on which a second gear 501 and a swing arm 507 are installed, the swing arm 507 is connected to the grinding shaft 505 in a ball pair, and the second gear 501 is meshed with the driving gear shaft 310 to realize power transmission; the grinding shaft 505 is rotatably connected to a bracket 506, the bracket 506 is slidably connected to the movable frame, the bracket 506 is rotatably connected to a cross shaft 508, the cross shaft 508 is rotatably connected to the swing arm 507, and the swing arm 507 is fixedly connected to a grinding ring 502; the grinding shaft 505 is transmission-connected to the cylinder 301 in the refinement zone.

[0035] When the hole wall needs to be refined and polished, the cylinder 301 is extended, and the second gear 501 begins to mesh with the driving gear shaft 310. After the main motor 307 is started, the driving gear shaft 310 drives the second gear 501, and the second gear 501 drives the polishing shaft 505 to rotate. Since the bracket 506 slides on the movable frame, the bracket 506 will not rotate. At this time, the polishing shaft 505 drives the swing arm 507 to swing, thereby realizing the continuous swing of the polishing circle 502. When the polishing circle 502 swings, since its outer wall surface is a spherical surface, the wall surface of the polishing circle 502 will continue to polish the hole wall after it is attached to the hole wall to prevent the hole wall from being too rough and causing damage to the subsequent inserted drainage pipe; after the polishing is completed, the cylinder 301 is retracted, and the second gear 501 is disengaged from the driving gear shaft 310.

[0036] like Figure 9-10 As shown, the roughening assembly 6 includes a roughening box 602, on which a third gear 601 is installed, and the third gear 601 is engaged with the driving gear shaft 310 to realize power transmission; the roughening box 602 is rotatably connected to a telescopic rod frame 610, on which a plurality of telescopic rods 603 are installed, and the telescopic rods 603 are slidably connected to the movable frame, and the telescopic rod frame 610 is fixedly connected to a fifth gear 609, and the roughening box 602 is rotatably connected to a telescopic rod frame 610. A lead screw 604 is connected, a fourth gear 608 is installed on the lead screw 604, the fourth gear 608 is meshed with the fifth gear 609, the roughening box 602 is slidably connected to a moving seat 607, the moving seat 607 is threadedly connected to the lead screw 604, the moving seat 607 is slidably connected to a carving tooth 606, an extrusion spring 605 is provided between the carving tooth 606 and the moving seat 607; the roughening box 602 is transmission-connected to the cylinder 301 in the roughening zone.

[0037] When the hole wall needs to be roughened, the cylinder 301 extends, and the third gear 601 begins to mesh with the driving gear shaft 310. After the main motor 307 is started, the driving gear shaft 310 drives the third gear 601 to rotate, and the third gear 601 drives the roughening box 602 to rotate, and the roughening box 602 drives the fourth gear 608 to revolve. Since the telescopic rod 603 is slidably connected to the movable frame, the telescopic rod frame 610 does not rotate, so the fourth gear 608 will start to rotate due to the meshing with the fifth gear 609. The revolution of the fourth gear 608 and the elastic force of the extrusion spring 605, The carving teeth 606 are pressed against the hole wall to carve, the telescopic rod 603 is pressed against the building body 2, and the self-rotation of the fourth gear 608 drives the lead screw 604 to rotate, so that the moving seat 607 moves horizontally on the roughening box 602, so that the motion trajectory of the carving teeth 606 is a spiral line, that is, the carving teeth 606 carve a spiral groove in the hole wall, and the telescopic rod 603 continues to shrink. After the carving is completed, the main motor 307 rotates in the opposite direction, so that the moving seat 607 returns to its original position, and the cylinder 301 retracts until the third gear 601 is disengaged from the driving gear shaft 310. Through the roughening operation, after the drainage pipe is arranged in the later stage, the spiral groove carved by the carving teeth 606 can be used when the foam glue is filled to enhance the adhesion between the foam glue and the building body 2 and prevent the seal from loosening.

[0038] In another specific embodiment, Figure 7-Figure 8 As shown, the opening shaft 405 is rotatably connected to the first connecting sleeve 403, a first spring 404 is arranged between the opening shaft 405 and the first connecting sleeve 403, and the first connecting sleeve 403 is mounted on the cylinder 301. The grinding shaft 505 is rotatably connected to the second connecting sleeve 503, a third spring 504 is arranged between the grinding shaft 505 and the second connecting sleeve 503, and the second connecting sleeve 503 is mounted on the cylinder 301. The first spring 404 and the third spring 504 have the same function, that is, when the opening assembly 4 or the thinning assembly 5 is working, since the cylinder 301 is extended at a uniform speed, the excavation speed of the opening teeth 408 or the grinding speed of the grinding ring 502 is determined according to the material of the building body 2. If hard materials such as stones appear locally on the building body 2, the operating speed will be reduced. In order to prevent the opening teeth 408 or the grinding ring 502 from being damaged, the first spring 404 or the third spring 504 is arranged for buffering.

[0039] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0040] Embodiment 3: This embodiment further expands the mounting frame 1 and the adjustment frame 3 on the basis of the above embodiment. Figure 5-Figure 6As shown, the movable frame includes a connecting plate 309, a protective frame 302, and a support plate 308. The ends of the connecting plate 309 are fixedly connected to the support plate 308 and the connecting plate 309 respectively. The support plate 308 is provided with holes for the opening component 4, the refinement component 5, and the coarsening component 6 to move. The fixed part includes a connecting arm 303, and the connecting arm 303 is rotatably connected to the connecting plate 309. An adjusting motor 304 is installed on the connecting arm 303, and an adjusting gear 305 is installed on the output end of the adjusting motor 304. A gear ring 306 is installed on the connecting plate 309, and the gear ring 306 is meshed with the adjusting gear 305.

[0041] According to the preset opening position on the building body 2, the adjusting motor 304 is started so that the adjusting gear 305 drives the ring gear 306 to rotate, and the ring gear 306 rotates the movable frame to change the height of the opening component 4, the refinement component 5, and the coarsening component 6 to make them level with the preset hole position height; thereby, drainage holes of different heights can be operated.

[0043] When the swing motor 105 is started, the worm 103 drives the worm wheel 104 to rotate, and the worm wheel 104 causes the adjusting shaft 107 to rotate synchronously. The rotation of the adjusting shaft 107 drives the connecting arm 303 to rotate the entire movable frame, so as to adjust the position and inclination angle of the movable frame, thereby realizing that the hole opening component 4, the refinement component 5, and the coarsening component 6 can perform drilling operations on vertical walls, inclined walls, and floors, and have a wider range of applications.

By adjusting the height of the mounting leg and cooperating with the rotating movable frame, the adaptability of the hole opening component 4, the thinning component 5, and the coarsening component 6 to holes in different positions is further enhanced.

[0045] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0046] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form.
