Description

Technical Field

[0001] The present invention belongs to the technical field of concrete hole-opening equipment, and specifically relates to a hole-opening machine for concrete protection doors. Background Art

[0002] A concrete protection door is an airtight door used in buildings, mainly providing functions such as fire protection, waterproofing, and sound insulation. This kind of door is usually made of reinforced concrete and has the characteristics of high strength and strong compressive capacity, so it is widely used in public buildings, commercial buildings, residential buildings and other fields.

[0003] A Chinese patent with the publication number CN208468751U discloses a concentric hole-opening machine for concrete protection doors, including a limiting barrel fixedly arranged on the lower plane of the frame. Two hydraulic cylinders I are fixedly arranged on the frame. Chains are respectively fixedly arranged on the piston rods of the two hydraulic cylinders I. The chains are fixedly connected with a heavy plate. The heavy plate is slidably connected with the limiting barrel. A servo motor is fixedly arranged on the frame, which has the advantages of high hole-opening efficiency, not easy to misalign during hole-opening, and low labor intensity of workers. Since the support plate is rotatably connected with the frame and the support plate can rotate around the frame, the hole positions for hole-opening can be realized on the circumference of a circle.

[0004] Currently, in the prior art, when performing hole-opening operations on concrete protection doors, usually, operators first need to drill holes at the specified hole-opening positions with an electric drill. When the holes are drilled, different drills are replaced to drill the drilled holes multiple times to make the opened hole diameters larger, thereby achieving the effect of hole-opening. This hole-opening method can greatly ensure the accuracy and stability during hole-opening, preventing the concrete protection door from cracking during hole-opening. However, due to the relatively numerous hole-opening steps, it will extremely consume the physical strength of operators during hole-opening operations and also reduce the hole-opening efficiency. Moreover, since concrete is composed of cement, water, sand, stones, etc., dust will be generated during hole-opening, and stone chips will fall out at the hole-opening site. After the hole-opening is completed, it is necessary to clean it again, which is rather troublesome.

[0005] Therefore, the present invention provides a hole-opening machine for concrete protection doors. Summary of the Invention

[0006] Therefore, the technical problem to be solved by the present invention is to overcome the problems that due to the relatively numerous hole-opening steps, it will extremely consume the physical strength of operators during hole-opening operations and also reduce the hole-opening efficiency, and since concrete is composed of cement, water, sand, stones, etc., dust will be generated during hole-opening, and stone chips will fall out at the hole-opening site, and it is necessary to clean it again after the hole-opening is completed.

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows: a concrete protection door drilling machine, including a support plate, a calibration box is fixedly installed at the bottom of the support plate, an adjustment mechanism is arranged inside the calibration box, and the adjustment mechanism is used to adjust the position of the device so that the device is aligned with the position to be drilled on the concrete protection door. A cavity tube is fixedly installed at the top of the support plate, and an expansion adjustment unit is arranged inside the cavity tube. The expansion adjustment unit includes soil repair knives, and the number of soil repair knives is multiple. The expansion adjustment unit is used to drive soil repair knives with different diameters to drill holes at the position to be drilled on the concrete protection door. An electric drill bit is arranged at the middle position inside the cavity tube, and the electric drill bit is placed inside the expansion adjustment unit. A dust cleaning unit is arranged outside one end of the cavity tube, and the dust cleaning unit includes a sprayer. The dust cleaning unit is used to collect and process the smoke, dust and stones drilled out during the hole drilling operation of the expansion adjustment unit on the concrete protection door when the expansion adjustment unit drills holes in the concrete protection door; During use, the concrete protection door is placed vertically, and then the position of the calibration box is controlled for adjustment so that the expansion adjustment unit is adjusted to a state horizontal with the center of the hole to be drilled. When the adjustment is completed, the expansion adjustment unit in the cavity tube is controlled to drive the electric drill bit to drill holes at the position to be drilled on the concrete protection door. When the drilling is completed, the expansion adjustment unit is continuously controlled to drive the soil repair knives to expand the holes drilled by the electric drill bit. When the expansion adjustment unit is operating, the dust cleaning unit cooperates with it to operate, so that when the expansion adjustment unit drills holes in the concrete protection door, the dust cleaning unit collects and processes the smoke, dust and stones drilled out by the expansion adjustment unit, saving the subsequent steps of cleaning the stone slag and dust at the hole after the hole drilling operation is completed, reducing the waste of manpower. First, the expansion adjustment unit drives the electric drill bit to drill holes at the position to be drilled on the concrete protection door. When the drilling is completed, the expansion adjustment unit is controlled to drive the soil repair knives to expand the holes drilled by the electric drill bit, eliminating the need for operators to frequently replace the drill bit, saving manpower and improving the hole drilling efficiency at the same time.

[0008] Preferably, the expansion adjustment unit further includes a tool adjustment component, a drilling component and a tool closing component. The drilling component includes a rotary cylinder, the output end of the rotary cylinder is fixedly installed with a rotating rod, one end of the rotating rod is fixedly installed with a connecting rod, and one end of the connecting rod is fixedly connected with one end of the electric drill bit. The electric drill bit is placed at the middle position inside one end of the cavity tube, and the drill bit end of the electric drill bit is exposed outside the cavity tube. Before drilling, by determining the diameter of the hole to be drilled, the tool adjustment component is controlled to adjust the distance between multiple soil repair knives, so as to adjust the diameters of multiple soil repair knives, so that the diameter of the annular tool holder formed by multiple soil repair knives can meet the diameter of the hole to be drilled. When the adjustment is completed, then the rotary cylinder is controlled to drive the connecting rod to rotate through the rotating rod, and when the connecting rod rotates, it drives the electric drill bit to rotate, so that the electric drill bit starts to realize the drilling operation on the concrete protection door.

[0009] Preferably, a drilling feed motor is fixedly installed at the top of the support plate, and a storage ring block is fixedly installed on the outer wall of the rotary cylinder. The output end of the drilling feed motor penetrates through the inner wall of the cavity tube and is fixedly connected to one side of the storage ring block. The outer wall of the storage ring block is slidably connected to the inner wall of the cavity tube. When the rotary cylinder drives the electric drill bit to rotate for drilling operations, the drilling feed motor slowly drives the rotary cylinder to move within the cavity tube through the storage ring block, thereby driving the electric drill bit to slowly extend from the cavity tube to drill the concrete protection door. When the electric drill bit finishes drilling the concrete protection door, through the cooperation of the drilling assembly and the knife combining assembly, the annular tool holder composed of multiple soil repair knives can be driven to rotate. When rotating, a reaming tool can be formed by high-speed rotation. By continuously driving the storage ring block to slide within the cavity tube through the drilling feed motor, the reaming tool formed by multiple soil repair knives will expand the hole drilled by the electric drill bit, thereby achieving the effect of opening a hole.

[0010] Preferably, the knife combining assembly includes a rotating shaft. An internal screw thread is provided on the inner wall of one end of the rotating shaft, and a screw interface is provided at one end of the connecting rod. The outer wall of the screw interface can be threadedly connected to the inner wall of the internal screw thread. The rotating shaft is placed outside the electric drill bit. A tool storage block is fixedly installed at one end of the rotating shaft. A hollow disc plate is fixedly installed inside the tool storage block. A plurality of soil breaking knives are slidably connected inside the tool storage block. The tops of the plurality of soil breaking knives are fixedly connected to the bottoms of the plurality of soil repair knives. A plurality of sliding knife rods are fixedly installed outside the hollow disc plate. The inner walls of the plurality of soil repair knives are respectively slidably connected to the inner walls of the plurality of sliding knife rods. A plurality of return knife springs are provided between the inner sides of the plurality of soil repair knives and the outer wall of the hollow disc plate. The plurality of return knife springs are respectively placed outside the plurality of sliding knife rods. The plurality of soil repair knives and soil breaking knives are both slidably connected to the inner wall of the tool storage block. By pushing the soil repair knife through the tool adjustment assembly to pull the return knife spring to slide on the sliding knife rod, the soil repair knife will move within the tool storage block. When moving, the soil repair knife drives the soil breaking knife to move together. When the tool adjustment assembly stops adjusting, the plurality of soil repair knives stop moving outwards. At this time, the plurality of soil repair knives and soil breaking knives will form a complete tool. When the electric drill bit finishes drilling the concrete protection door, one end of the connecting rod will rotate into the inner part of one end of the rotating shaft, and the screw interface on one end of the connecting rod will be tightened into the internal screw thread inside the rotating shaft. When the screw interface is completely screwed into the internal screw thread, the connecting rod drives the rotating shaft to rotate, thereby driving the tool formed by the soil repair knife and the soil breaking knife to rotate through the tool storage block. By continuously pushing the connecting rod through the drilling feed motor, the tool will perform reaming operations on the hole drilled by the electric drill bit through high-speed rotation. During reaming, the soil breaking knife breaks the concrete, and the soil repair knife scrapes the concrete broken by the soil breaking knife, so that the hole opened is smooth and tidy, thereby achieving the effect of opening a hole. By opening a hole in this way, there is no need to replace different drill bits during hole opening, which is more conducive to hole opening operations.

[0011] Preferably, a tool guide ring is fixedly installed at one end of the tool storage block. A plurality of soil expanding blades are fixedly installed on the outer wall of the tool guide ring. A plurality of blade sliding grooves are formed in the inner wall of the tool guide ring. The bottom ends of the plurality of soil breaking blades are respectively slidably connected to the inner walls of the plurality of blade sliding grooves. When the tool storage block rotates, it also drives the tool guide ring at the bottom of the tool storage block to rotate. When the tool guide ring rotates, it drives the plurality of soil expanding blades outside it to rotate. When the electric drill bit finishes its operation, the feed drill motor drives the connecting rod to continuously advance. During the advancing process, the soil expanding blades on the tool guide ring will first approach the hole opening to slightly expand the hole opening. Subsequently, through the advancement of the feed drill motor, the soil repairing blades and the soil breaking blades will further expand and repair the hole, playing a role in transitional hole expansion, preventing the soil repairing blades and the soil breaking blades from not being able to enter the hole due to the outer end of the tool storage block being a tapered ring shape. At the same time, on the other hand, it avoids the tool storage block from frictionally drilling at the concrete hole during high-speed rotation, resulting in cracking, breaking, etc. at the hole opening.

[0012] Preferably, an inner tube is fixedly installed on the inner wall of the cavity tube. A limiting ring is fixedly installed on the inner wall of the inner tube. A sliding ring is slidably connected to the inner wall of the inner tube. A plurality of shaft rods are fixedly installed on the inner side of the sliding ring. A ring groove is formed in the inner wall of one end of the rotating shaft. A plate frame is slidably connected to the inner wall of the ring groove. One ends of the plurality of shaft rods all penetrate through the inner wall of the limiting ring and are fixedly connected to one side of the plate frame. The outer walls of the plurality of shaft rods are all slidably connected to the inner wall of the limiting ring. A plurality of reset springs are arranged between the sliding ring and the limiting ring. The plurality of reset springs are respectively disposed outside the plurality of shaft rods. The outer wall of the plate frame is slidably connected to the inner wall of the inner tube. When the feed drill motor drives the rotating shaft to continuously advance through the connecting rod, the rotating shaft pulls the sliding ring to slide in the inner tube through the plate frame. When sliding, the sliding ring squeezes the reset springs to slide. When the hole opening operation ends, the rotating cylinder drives the connecting rod to reverse, and the feed drill motor drives the rotating cylinder and the connecting rod to return. The screw interface will then rotate out of the internal screw port, thereby driving the electric drill bit to retract into the cavity tube. At the same time, the rotating shaft is reset under the driving force of the elastic force of the reset springs, avoiding the rotating shaft from losing power and being unable to reset when the screw interface rotates out of the internal screw port, playing a role in resetting the rotating shaft.

[0013] Preferably, the tool adjusting assembly includes a tool pressing block. The tool pressing block is slidably arranged inside the cavity tube. The outer wall of the tool pressing block is slidably connected to the tops of the plurality of soil repairing blades. A ring plate is fixedly installed on the outer wall of the tool pressing block. A plurality of through grooves are formed in the inner wall of the rotating shaft. The inner rod of the ring plate is slidably connected to the inner walls of the plurality of through grooves. An annular motor is fixedly installed on the outer wall of the inner tube. The output end of the annular motor is fixedly installed with a rod frame plate. One end of the rod frame plate is rotatably connected to the inner wall of the ring plate. By controlling the annular motor to drive the ring plate to slide on the rotating shaft, when the ring plate slides, it drives the tool pressing block to squeeze the inner walls of the plurality of soil repairing blades, thereby pushing the plurality of soil repairing blades and the soil breaking blades to move outwards, so as to adjust the distance between the plurality of soil repairing blades and the soil breaking blades, making the distance between them the same as the aperture of the hole opening, playing a role in adjusting the tool size.

[0014] Preferably, the ash cleaning unit further includes an air extraction fan block, which is fixedly installed outside the annular disc plate. A water injector is fixedly installed on the outer wall of the cavity tube. The water injector is arranged outside the annular motor. A ring shell is fixedly installed on the outer wall of the water injector. A sprayer is fixedly installed on the inner wall of the ring shell. A water flow pipe is fixedly installed between the sprayer and the water injector. A slag baffle is fixedly installed at one end of the ring shell, and the slag baffle is fixedly installed at one end of the cavity tube. The inner side of the air extraction fan block is a curved arc surface fan blade, and the outer side is a flat surface. During operation, gas is drawn in from the outside to the inside. Through the arrangement of the inner rod of the annular disc plate, the annular disc plate will also be driven to rotate. When the annular disc plate rotates, it drives multiple air extraction fan blocks to rotate. When the multiple air extraction fan blocks rotate, air flow is generated. Due to the inner side of the air extraction fan block being a curved arc surface fan blade and the outer side being a flat surface, when the air flow is generated, air can be drawn in from the outside. Thus, when performing hole-opening operations on the concrete protection door, the air extraction fan blocks rotate continuously to perform air extraction operations on the hole-opening area, and the dust generated by the hole-opening is drawn into the ring shell. When the dust enters the ring shell, the water injector injects water into the sprayer through the water flow pipe, and the water injector sprays and disperses the injected water. Driven by the wind generated by the air extraction fan block, the water mist sprayed by the sprayer will come into contact with the dust drawn in by the air extraction fan block, thereby eliminating the dust generated by the hole-opening and playing a role in removing smoke.

[0015] Preferably, a cleaning plate water box is fixedly installed on the top of the ring shell. A water sliding port is opened on the inner wall of the upper surface of the ring shell, and a leakage groove is opened on the lower surface of the ring shell. A water sliding plate is arranged on the inner side of the water injector. When the water mist is sprayed by the sprayer, driven by the wind generated by the air extraction fan block, the water mist will be blown onto the water sliding plate. Driven by the gas, the drawn-in dust will also be blown onto the water sliding plate. When the dust comes into contact with the water on the water sliding plate, the water will cool the high-temperature flue gas and absorb the particulate matter in the flue gas, thereby reducing the temperature of the flue gas and reducing the diffusion of harmful substances, thus achieving the effect of smoke removal. The precipitated impurities will be adsorbed on the water sliding plate. When there is too much on the water sliding plate, by pouring water from the cleaning plate water box, the water will flow down from the top of the water sliding plate along the water sliding port and finally flow out from the leakage groove at the bottom of the ring shell, thereby realizing the cleaning of the water sliding plate.

[0016] Preferably, a positioning block is fixedly installed on the top of the calibration box, the positioning block and the center of the support plate are in the same horizontal state, a positioning motor is fixedly installed on one side of the positioning block, a sliding shaft is fixedly installed on the inner wall of the positioning block, a positioning plate is provided at the bottom of the sliding shaft, one end of the positioning plate is fixedly connected to the other side of the positioning block, a telescopic rod is movably connected to the outer wall of the sliding shaft, one end of the telescopic rod and one side of the top of the support plate are fixedly installed with a slag collecting box, a hollow shaft is fixedly installed on the output end of the positioning motor, one end of the hollow shaft is fixedly connected to one side of the sliding end of the telescopic rod, wherein a drawer is provided inside the slag collecting box placed on one side of the top of the support plate, and the drawer is placed directly below one end of the annular shell, and the concrete protective door is erected and one side of the protective door is placed in the positioning block, and the calibration box is controlled to adjust the position so that the expansion unit Adjust it to a state that is horizontal with the center of the opening. When the adjustment is completed, the positioning motor is then controlled to drive the telescopic rod to slide on the sliding shaft through the hollow shaft. When the slag collecting box on one end of the telescopic rod touches one side of the concrete protection door, the positioning motor stops operating. At this time, the two slag collecting boxes will be placed on both sides of the opening of the concrete protection door, so that when the adjustment and expansion unit is performing the opening operation, the two slag collecting boxes can receive the soil debris coming out of the opening to prevent the soil debris from falling on the ground and requiring subsequent cleaning. When the soil debris in the two slag collecting boxes is full, since water flow will be generated inside one of the slag collecting boxes when collecting debris, the soil debris in the dry slag collecting box can be poured out by pushing the telescopic rod to rotate on the sliding shaft, and the soil debris collected inside can be cleared by pulling the drawer out of the wet slag collecting box.

[0017] The beneficial effects of the present invention are as follows: 1. The concrete protection door hole opening machine described in the present invention, when the electric drill bit completes drilling the hole in the concrete protection door, the screw interface on one end of the connecting rod will be tightly inserted into the inner screw hole in the rotating shaft, and the connecting rod can drive the rotating shaft to rotate, thereby driving the tool formed by the soil repair knife and the soil crushing knife to rotate through the knife storage block, and the connecting rod is driven to continuously advance by the drill feed motor, and the tool will expand the hole drilled by the electric drill bit through high-speed rotation. During the hole expansion, the soil crushing knife will crush the concrete, and the soil repair knife will scrape and repair the concrete crushed by the soil crushing knife, so that the opened hole is smooth and tidy, thereby achieving the effect of opening the hole. When opening the hole by this method, there is no need to replace different drill bits when opening the hole, which is more conducive to the hole opening operation.

[0018] 2. The concrete protective door hole opening machine described in the present invention drives the knife ring to rotate when the knife storage block rotates, and the knife ring drives multiple soil expanding knives outside it to rotate when the knife storage block rotates. When the electric drill head finishes the operation, the drill feed motor drives the connecting rod to continue to advance. During the advancement, the soil expanding knife on the knife ring will first approach the hole opening to slightly expand the hole opening, and then through the advancement of the drill feed motor, the soil repair knife and the soil crushing knife will expand and repair the hole, which plays a role of transitional hole expansion, preventing the soil repair knife and the soil crushing knife from being unable to enter the hole during hole expansion due to the conical ring shape of the outer end of the knife storage block, and at the same time, preventing the knife storage block from frictionally drilling into the hole in the concrete when rotating at high speed, resulting in cracking, breakage and the like at the hole opening.

[0019] 3. The concrete protection door hole opening machine described in the present invention controls the annular motor to drive the annular disc plate to slide on the rotating shaft. When the annular disc plate slides, it drives the knife pressing block to squeeze the inner walls of multiple soil repair knives, thereby pushing the multiple soil repair knives and soil crushing knives to move outward, thereby adjusting the distance between the multiple soil repair knives and soil crushing knives so that the distance between them is the same as the aperture of the hole, thereby playing the role of adjusting the tool size, so that the device can open holes of different diameters without changing the drill bit.

[0020] 4. The concrete protection door opening machine described in the present invention drives the annular disc plate to rotate when the rotating cylinder rotates, and the rotation of the annular disc plate drives multiple exhaust fan blocks to rotate to generate airflow. The inner side of the exhaust fan block is a curved fan blade, and the outer side is a plane. When airflow is generated, airflow can be drawn in from the outside, so that when the concrete protection door is opened, the exhaust fan block is rotated to continuously exhaust air at the opening, and the smoke and dust generated by the opening is sucked into the annular shell. When the smoke and dust enters the annular shell, the water injector injects water into the sprayer through the water flow pipe, and the water injector sprays the injected water out. The wind force generated by the exhaust fan block blows, and the water mist sprayed by the sprayer will contact the smoke and dust sucked in by the exhaust fan block, thereby eliminating the smoke and dust generated by the opening, thereby playing a role in smoke removal.

[0021] 5. The concrete protection door hole opening machine described in the present invention drives the telescopic rod to slide on the sliding shaft through the hollow shaft by controlling the positioning motor. When the slag collecting box on one end of the telescopic rod contacts one side of the concrete protection door, the positioning motor stops operating. At this time, the two slag collecting boxes will be respectively placed on both sides of the opening of the concrete protection door. When the adjustment and expansion unit performs the hole opening operation, the two slag collecting boxes will receive the soil debris discharged from the hole to prevent the soil debris from falling on the ground and requiring subsequent cleaning, thereby reducing the workload of the operators and thus alleviating the work pressure of the staff.

Detailed implementation manners

[0025] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with the detailed implementation manners.

[0026] AsFigures 1 to 12 As shown in the figure, a concrete protection door drilling machine according to an embodiment of the present invention includes a support plate 21. A calibration box 1 is fixedly installed at the bottom of the support plate 21. An adjustment mechanism is arranged inside the calibration box 1. The adjustment mechanism is used to adjust the position of the device so as to calibrate the position of the device with the position to be drilled on the concrete protection door. A cavity tube 8 is fixedly installed at the top of the support plate 21. An expansion adjustment unit is arranged inside the cavity tube 8. The expansion adjustment unit includes soil repair knives 8602, and the number of the soil repair knives 8602 is multiple. The expansion adjustment unit is used to drive the soil repair knives 8602 with different diameters to drill holes at the position to be drilled on the concrete protection door. An electric drill bit 85 is arranged at the middle position inside the cavity tube 8, and the electric drill bit 85 is placed inside the expansion adjustment unit. A dust cleaning unit is arranged outside one end of the cavity tube 8. The dust cleaning unit includes a sprayer 91. The dust cleaning unit is used to collect and process the dust and stones drilled out during the hole drilling operation when the expansion adjustment unit drills holes in the concrete protection door. Since the hole drilling steps are relatively numerous, it will extremely consume the physical strength of the operators and reduce the hole drilling efficiency during the hole drilling operation. Moreover, since concrete is composed of cement, water, sand, stones, etc., dust will be generated during the hole drilling, and stone chips will fall out at the hole drilling position. After the hole drilling is completed, it is necessary to clean again. During use, the concrete protection door is placed vertically, and then the position of the calibration box 1 is controlled to be adjusted so that the expansion adjustment unit is adjusted to a state horizontal with the center of the hole to be drilled. When the adjustment is completed, the expansion adjustment unit in the cavity tube 8 is controlled to drive the electric drill bit 85 to drill holes at the position to be drilled on the concrete protection door. When the drilling is completed, the expansion adjustment unit is continuously controlled to drive the soil repair knives 8602 to perform reaming operations on the holes drilled by the electric drill bit 85. When the expansion adjustment unit is operating, the dust cleaning unit cooperates with it to operate. When the expansion adjustment unit drills holes in the concrete protection door, the dust cleaning unit collects and processes the dust and stones drilled out by the expansion adjustment unit, saving the subsequent steps of cleaning the stone chips and dust after the hole drilling operation and reducing the waste of manpower. By first driving the electric drill bit 85 to drill holes at the position to be drilled on the concrete protection door by the expansion adjustment unit, and when the drilling is completed, controlling the expansion adjustment unit to drive the soil repair knives 8602 to perform reaming operations on the holes drilled by the electric drill bit 85, there is no need for the operator to frequently replace the drill bit, saving manpower and improving the hole drilling efficiency at the same time, thus solving the problems in the prior art that since the hole drilling steps are relatively numerous, it will extremely consume the physical strength of the operators and reduce the hole drilling efficiency during the hole drilling operation, and since concrete is composed of cement, water, sand, stones, etc., dust will be generated during the hole drilling, and stone chips will fall out at the hole drilling position, and it is necessary to clean again after the hole drilling is completed.

[0027] As Figures 3 to 11As shown, the adjusting and expanding unit further includes a tool adjusting component, a drilling component, and a tool closing component. The drilling component includes a rotary cylinder 7. The output end of the rotary cylinder 7 is fixedly installed with a rotating rod 23. One end of the rotating rod 23 is fixedly installed with a connecting rod 81. One end of the connecting rod 81 is fixedly connected to one end of an electric drill bit 85. The electric drill bit 85 is placed at the middle position inside one end of the cavity tube 8, and the drill bit end of the electric drill bit 85 is exposed outside the cavity tube 8. Since the soil repairing tool 8602 is annularly arranged, before opening the hole, by determining the diameter of the hole to be opened, the tool adjusting component is controlled to adjust the distance between multiple soil repairing tools 8602, so as to adjust the diameters of multiple soil repairing tools 8602, so that the diameter of the annular tool holder formed by multiple soil repairing tools 8602 can meet the diameter of the hole to be opened. When the adjustment is completed, then the rotary cylinder 7 is controlled to drive the connecting rod 81 to rotate through the rotating rod 23. When the connecting rod 81 rotates, it drives the electric drill bit 85 to rotate, so that the electric drill bit 85 is started, and the drilling operation on the concrete protection door is realized.

[0028] As Figures 3 to 4 As shown, a drilling feed motor 2 is fixedly installed at the top of the support plate 21. A storage ring block 22 is fixedly installed on the outer wall of the rotary cylinder 7. The output end of the drilling feed motor 2 penetrates through the inner wall of the cavity tube 8 and is fixedly connected to one side of the storage ring block 22. The outer wall of the storage ring block 22 is slidably connected to the inner wall of the cavity tube 8. When the rotary cylinder 7 drives the electric drill bit 85 to rotate for drilling operation, the drilling feed motor 2 slowly drives the rotary cylinder 7 to move in the cavity tube 8 through the storage ring block 22, so as to drive the electric drill bit 85 to slowly extend out of the cavity tube 8 to drill the concrete protection door. When the drilling of the concrete protection door by the electric drill bit 85 is completed, through the mutual cooperation of the drilling component and the tool closing component, the annular tool holder composed of multiple soil repairing tools 8602 can be driven to rotate. When rotating, a hole expanding tool can be formed by high-speed rotation. By continuously driving the storage ring block 22 to slide in the cavity tube 8 by the drilling feed motor 2, the hole expanding tool formed by multiple soil repairing tools 8602 will expand the hole drilled by the electric drill bit 85, so as to achieve the effect of opening the hole. As Figures 6 to 9As shown, the knife combining component includes a rotating shaft 83. An internal screw thread 8301 is provided on the inner wall at one end of the rotating shaft 83.

The plurality of soil-repairing knives 8602 and soil-breaking knives 8601 are both slidably connected to the inner wall of the tool storage block 86; Before use, through the tool adjustment component, the soil-repairing knife 8602 is pushed to pull the return knife spring 8603 to slide on the sliding knife rod 8605. The soil-repairing knife 8602 will then move in the tool storage block 86. When moving, the soil-repairing knife 8602 drives the soil-breaking knife 8601 to move together. When the tool adjustment component stops adjusting, the plurality of soil-repairing knives 8602 stop moving outwards. At this time, the plurality of soil-repairing knives 8602 and soil-breaking knives 8601 will form a complete tool. When the electric drill bit 85 finishes drilling a hole in the concrete protection door, one end of the connecting rod 81 will rotate into the inner part of one end of the rotating shaft 83. The screw connection port 8101 at one end of the connecting rod 81 will be tightened into the internal screw thread 8301 inside the rotating shaft 83. When the screw connection port 8101 is completely screwed into the internal screw thread 8301, the connecting rod 81 drives the rotating shaft 83 to rotate, thereby driving the tool formed by the soil-repairing knife 8602 and the soil-breaking knife 8601 to rotate through the tool storage block 86. Through the feeding drill motor 2 driving the connecting rod 81 to continuously advance, the tool will perform reaming operation on the hole drilled by the electric drill bit 85 through high-speed rotation. During reaming, the soil-breaking knife 8601 breaks the concrete, and the soil-repairing knife 8602 scrapes and repairs the concrete broken by the soil-breaking knife 8601, so that the hole at the hole is smooth and tidy, thus achieving the effect of opening a hole. By opening a hole in this way, there is no need to replace different drill bits during hole opening, which is more conducive to hole opening operation. The setting of the return knife spring 8603 is for when the operation is over, the return knife spring 8603 drives the soil-repairing knife 8602 and the soil-breaking knife 8601 to return to the tool storage block 86.

[0029] As Figures 9 to 10As shown, a knife ferry ring 87 is fixedly installed at one end of the tool storage block 86. A plurality of soil spreading knives 8702 are fixedly installed on the outer wall of the knife ferry ring 87. A plurality of knife sliding grooves 8701 are formed in the inner wall of the knife ferry ring 87. The bottom ends of a plurality of soil breaking knives 8601 are respectively slidably connected to the inner walls of the plurality of knife sliding grooves 8701; Since the outer end of the tool storage block 86 is in a conical ring shape, when the tool storage block 86 rotates, it also drives the knife ferry ring 87 at the bottom of the tool storage block 86 to rotate. When the knife ferry ring 87 rotates, it drives the plurality of soil spreading knives 8702 outside it to rotate. When the operation of the electric drill bit 85 ends, the feed drill motor 2 drives the connecting rod 81 to continuously advance. During the advancing process, the soil spreading knives 8702 on the knife ferry ring 87 will first approach the hole opening to slightly expand the hole opening, and then through the advancement of the feed drill motor 2, the soil repairing knife 8602 and the soil breaking knives 8601 will further expand and repair the hole, playing a role in transitional hole expansion, preventing the soil repairing knife 8602 and the soil breaking knives 8601 from not being able to enter the hole due to the outer end of the tool storage block 86 being in a conical ring shape during hole expansion. At the same time, on the other hand, it avoids the tool storage block 86 from frictionally drilling at the concrete hole during high-speed rotation, resulting in phenomena such as cracking and breaking at the hole opening.

[0030] As Figures 6 to 7 As shown, an inner pipe 82 is fixedly installed on the inner wall of the cavity pipe 8. A limiting ring 8204 is fixedly installed on the inner wall of the inner pipe 82. A sliding ring 8201 is slidably connected to the inner wall of the inner pipe 82. A plurality of shaft rods 8203 are fixedly installed on the inner side of the sliding ring 8201. A ring groove 8302 is formed in the inner wall at one end of the rotating shaft 83. A plate frame 84 is slidably connected to the inner wall of the ring groove 8302. One ends of the plurality of shaft rods 8203 all penetrate through the inner wall of the limiting ring 8204 and are fixedly connected to one side of the plate frame 84. The outer walls of the plurality of shaft rods 8203 are all slidably connected to the inner wall of the limiting ring 8204. A plurality of return springs 8202 are arranged between the sliding ring 8201 and the limiting ring 8204. The plurality of return springs 8202 are respectively disposed outside the plurality of shaft rods 8203. The outer wall of the plate frame 84 is slidably connected to the inner wall of the inner pipe 82; When the feed drill motor 2 drives the rotating shaft 83 to continuously advance and operate through the connecting rod 81, the rotating shaft 83 pulls the sliding ring 8201 to slide in the inner pipe 82 through the plate frame 84. During the sliding, the sliding ring 8201 squeezes the return springs 8202 to slide. When the hole opening operation ends, the rotating cylinder 7 drives the connecting rod 81 to reverse, and the feed drill motor 2 drives the rotating cylinder 7 and the connecting rod 81 to return. The screw interface 8101 will then rotate out of the internal screw port 8301, thereby driving the electric drill bit 85 to retract into the cavity pipe 8. At the same time, the rotating shaft 83 is reset under the driving force of the elastic force of the return springs 8202, avoiding the rotating shaft 83 from losing power and being unable to reset when the screw interface 8101 rotates out of the internal screw port 8301, playing a role in resetting the rotating shaft 83.

[0031] As Figures 6 to 9As shown, the tool adjustment assembly includes a knife pressing block 1201. The knife pressing block 1201 is slidably disposed inside the cavity tube 8. The outer wall of the knife pressing block 1201 is slidably connected to the tops of a plurality of soil repairing knives 8602. An annular disk plate 12 is fixedly installed on the outer wall of the knife pressing block 1201. A plurality of through grooves 8303 are formed in the inner wall of the rotating shaft 83. The inner rod of the annular disk plate 12 is slidably connected to the inner walls of the plurality of through grooves 8303. An annular motor 10 is fixedly installed on the outer wall of the inner tube 82. The output end of the annular motor 10 is fixedly installed with a rod support plate 11. One end of the rod support plate 11 is rotatably connected to the inner wall of the annular disk plate 12; When the aperture of the hole to be opened is determined, by controlling the annular motor 10 to drive the annular disk plate 12 to slide on the rotating shaft 83, when the annular disk plate 12 slides, it drives the knife pressing block 1201 to squeeze the inner walls of the plurality of soil repairing knives 8602, thereby pushing the plurality of soil repairing knives 8602 and the soil crushing knives 8601 outward, so as to adjust the distance between the plurality of soil repairing knives 8602 and the soil crushing knives 8601, making the distance between them the same as the aperture of the hole to be opened, playing a role in adjusting the tool size.

[0032] As Figures 3 to 5 As shown, the dust cleaning unit further includes an air extraction fan block 93. The air extraction fan block 93 is fixedly installed outside the annular disk plate 12. A water injector 9 is fixedly installed on the outer wall of the cavity tube 8. The water injector 9 is disposed outside the annular motor 10. An annular shell 5 is fixedly installed on the outer wall of the water injector 9. A sprayer 91 is fixedly installed on the inner wall of the annular shell 5. A water flow pipe 92 is fixedly installed between the sprayer 91 and the water injector 9. One end of the annular shell 5 is fixedly installed with a slag baffle 94. The slag baffle 94 is fixedly installed at one end of the cavity tube 8. The inner side of the air extraction fan block 93 is a curved arc surface fan blade, and the outer side is a plane, and gas is drawn in from the outside during operation; When the rotating shaft 83 rotates, due to the setting of the inner rod of the annular disk plate 12, the annular disk plate 12 will also be driven to rotate. When the annular disk plate 12 rotates, it drives the plurality of air extraction fan blocks 93 to rotate. When the plurality of air extraction fan blocks 93 rotate, an air flow is generated. Since the inner side of the air extraction fan block 93 is a curved arc surface fan blade and the outer side is a plane, when the air flow is generated, air can be drawn in from the outside. Thus, when performing hole opening operation on the concrete protection door, the air extraction fan block 93 rotates continuously to perform air extraction operation on the hole opening, so as to draw the dust generated by the hole opening into the annular shell 5. When the dust enters the annular shell 5, the water injector 9 injects water into the sprayer 91 through the water flow pipe 92. The water injector 9 sprays and disperses the injected water. Driven by the wind generated by the air extraction fan block 93, the water mist sprayed by the sprayer 91 will contact the dust drawn in by the air extraction fan block 93, thereby eliminating the dust generated by the hole opening, playing a role in removing smoke.

[0033] As Figures 3 to 5As shown, a clean plate water box 6 is fixedly installed on the top of the ring shell 5, a water slide 61 is opened on the inner wall of the upper surface of the ring shell 5, a drain groove is opened on the lower surface of the ring shell 5, and a water slide is provided on the inner side of the water injector 9; When the water mist sprayed by the sprayer 91 is blown by the wind force generated by the exhaust fan block 93, the water mist will be blown onto the water ski board. Driven by the gas, the smoke and dust sucked in will also be blown onto the water ski board. When the smoke and dust come into contact with the water on the water ski board, the water will cool the high-temperature smoke and absorb the particulate matter in the smoke, thereby lowering the smoke temperature and reducing the diffusion of harmful substances, thereby achieving the effect of smoke removal. The precipitated impurities will be adsorbed on the water ski board. When there are too many water skis, water can be poured into the water box 6, and the water will flow down from the top of the water ski board along the water ski port 61, and finally flow out from the leakage groove at the bottom of the ring shell 5, thereby achieving the cleaning of the water ski board. like Figures 1 to 12 As shown, a positioning block 3 is fixedly installed on the top of the calibration box 1, and the positioning block 3 and the center of the support plate 21 are in the same horizontal state, a positioning motor 31 is fixedly installed on one side of the positioning block 3, a sliding shaft 32 is fixedly installed on the inner wall of the positioning block 3, and a mounting plate 43 is arranged at the bottom of the sliding shaft 32, one end of the mounting plate 43 is fixedly connected to the other side of the positioning block 3, and a telescopic rod 42 is movably connected to the outer wall of the sliding shaft 32, and a slag collecting box 4 is fixedly installed on one end of the telescopic rod 42 and one side of the top of the support plate 21, and a hollow shaft 33 is fixedly installed on the output end of the positioning motor 31, and one end of the hollow shaft 33 is fixedly connected to one side of the sliding end of the telescopic rod 42, wherein a drawer 41 is arranged inside the slag collecting box 4 placed on one side of the top of the support plate 21, and the drawer 41 is placed directly below one end of the annular shell 5; Before the operation, the concrete protection door is erected, one side of the protection door is placed in the positioning block 3, and the calibration box 1 is controlled to adjust the position so that the adjustment and expansion unit is adjusted to a state horizontal with the center of the opening. When the adjustment is completed, the adjustment motor 31 is then controlled to drive the telescopic rod 42 to slide on the sliding shaft 32 through the hollow shaft 33. When the slag collecting box 4 on one end of the telescopic rod 42 contacts one side of the concrete protection door, the adjustment motor 31 is stopped. At this time, the two slag collecting boxes 4 will be respectively placed on both sides of the opening of the concrete protection door, which is convenient for the adjustment and expansion unit to perform the opening operation. The two slag collecting boxes 4 receive the soil debris from the openings to prevent the soil debris from falling on the ground and needing to be cleaned up later. When the soil debris in the two slag collecting boxes 4 is full, water flow will be generated inside one of the slag collecting boxes 4 when collecting debris. By pushing the telescopic rod 42 to rotate on the sliding shaft 32, the soil debris in the dry slag collecting box 4 can be poured out, and by pulling the drawer 41 out of the wet slag collecting box 4, the soil debris collected inside can be cleared. It should be noted here that the side of the support plate 21 on which the slag collecting box 4 is installed is on the same horizontal line as the inner wall of one side of the positioning block 3.

[0034] Working principle: When in use, place the concrete protection door vertically, and then control the alignment box 1 to adjust its position so that the expansion unit is adjusted to a state horizontal with the center of the opening. When the adjustment is completed, the expansion unit in the control cavity tube 8 drives the electric drill bit 85 to drill at the position where the concrete protection door needs to be opened. When the drilling is completed, continue to control the expansion unit to drive the soil repair knife 8602 to perform reaming operation on the hole drilled by the electric drill bit 85. While the expansion unit is operating, the dust cleaning unit cooperates with it to collect and process the smoke, dust and stones drilled out by the expansion unit during the opening operation of the concrete protection door, saving the subsequent steps of cleaning the slag and dust at the opening after the opening operation is completed, reducing the waste of manpower. First, the expansion unit drives the electric drill bit 85 to drill at the position where the concrete protection door needs to be opened. When the drilling is completed, control the expansion unit to drive the soil repair knife 8602 to perform reaming operation on the hole drilled by the electric drill bit 85, eliminating the need for operators to frequently replace the drill bit, saving manpower and improving the opening efficiency at the same time; Before opening the hole, by determining the diameter of the opening, control the tool adjustment assembly to adjust the distance between multiple soil repair knives 8602, so as to adjust the diameter of multiple soil repair knives 8602, so that the diameter of the annular tool holder formed by multiple soil repair knives 8602 can meet the diameter of the opening. When the adjustment is completed, then control the rotary cylinder 7 to drive the connecting rod 81 to rotate through the rotating rod 23. When the connecting rod 81 rotates, it drives the electric drill bit 85 to rotate, so that the electric drill bit 85 is started to realize the drilling operation on the concrete protection door; When the rotary cylinder 7 drives the electric drill bit 85 to rotate for drilling operation, the feed drill motor 2 slowly drives the rotary cylinder 7 to move in the cavity tube 8 through the object receiving ring block 22, so as to drive the electric drill bit 85 to slowly extend from the cavity tube 8 to drill the concrete protection door. When the electric drill bit 85 finishes drilling the concrete protection door, through the cooperation of the drilling assembly and the knife closing assembly, the annular tool holder composed of multiple soil repair knives 8602 can be driven to rotate. When rotating, a reaming tool can be formed by high-speed rotation. By continuing to drive the object receiving ring block 22 to slide in the cavity tube 8 by the feed drill motor 2, the reaming tool formed by multiple soil repair knives 8602 will expand the hole drilled by the electric drill bit 85, thus realizing the opening effect; The soil-repairing knife 8602 is pushed by the tool-adjusting component to pull the return knife spring 8603 and slide on the knife-sliding rod 8605. Then the soil-repairing knife 8602 will move on the tool-storage block 86. When moving, the soil-repairing knife 8602 drives the soil-crushing knife 8601 to move together. When the tool-adjusting component stops adjusting, multiple soil-repairing knives 8602 stop moving outwards. At this time, multiple soil-repairing knives 8602 and the soil-crushing knife 8601 will form a complete tool. When the electric drill bit 85 finishes drilling the concrete protection door, one end of the connecting rod 81 will rotate into the inner part of one end of the rotating shaft 83, and the screw interface 8101 on one end of the connecting rod 81 will be tightened into the internal screw thread 8301 in the rotating shaft 83. When the screw interface 8101 is completely screwed into the internal screw thread 8301, the connecting rod 81 drives the rotating shaft 83 to rotate, so as to drive the tool formed by the soil-repairing knife 8602 and the soil-crushing knife 8601 to rotate through the tool-storage block 86. By driving the connecting rod 81 to continuously advance by the feed drill motor 2, the tool will perform reaming operation on the hole drilled by the electric drill bit 85 through high-speed rotation. During reaming, the soil-crushing knife 8601 breaks the concrete, and the soil-repairing knife 8602 scrapes and repairs the concrete broken by the soil-crushing knife 8601, so that the hole at the opening is smooth and tidy, thus realizing the opening effect. By opening the hole in this way, there is no need to replace different drill bits during opening, which is more conducive to the opening operation; When the tool-storage block 86 rotates, it also drives the tool-transition ring 87 at the bottom of the tool-storage block 86 to rotate. When the tool-transition ring 87 rotates, it drives multiple soil-expanding knives 8702 outside it to rotate. When the operation of the electric drill bit 85 ends, the feed drill motor 2 drives the connecting rod 81 to continuously advance. During the advancing process, the soil-expanding knives 8702 on the tool-transition ring 87 will first approach the hole opening to slightly expand the hole opening, and then through the advancement of the feed drill motor 2, the soil-repairing knife 8602 and the soil-crushing knife 8601 will ream the hole, playing a role of transitional reaming, preventing the soil-repairing knife 8602 and the soil-crushing knife 8601 from not being able to enter the hole during reaming because the outer end of the tool-storage block 86 is conical annular, and on the other hand, avoiding the tool-storage block 86 from frictionally drilling into the concrete hole during high-speed rotation, resulting in cracking, breaking and other phenomena at the hole opening; When the feed drill motor 2 drives the rotating shaft 83 to continuously advance and operate through the connecting rod 81, the rotating shaft 83 pulls the sliding ring 8201 to slide in the inner tube 82 through the plate frame 84. When sliding, the sliding ring 8201 squeezes the return spring 8202 to slide. When the opening operation ends, the rotating cylinder 7 drives the connecting rod 81 to reverse, and the feed drill motor 2 drives the rotating cylinder 7 and the connecting rod 81 to return. The screw interface 8101 will rotate out of the internal screw thread 8301, so as to drive the electric drill bit 85 to retract into the cavity tube 8. At the same time, the rotating shaft 83 is reset under the driving of the elastic force of the return spring 8202, avoiding that when the screw interface 8101 rotates out of the internal screw thread 8301, the rotating shaft 83 loses power and cannot be reset, playing a role of resetting the rotating shaft 83; By controlling the ring-shaped motor 10 to drive the ring plate 12 to slide on the rotating shaft 83, when the ring plate 12 slides, it drives the pressing knife block 1201 to squeeze the inner walls of multiple soil-repairing knives 8602, thereby pushing multiple soil-repairing knives 8602 and soil-crushing knives 8601 to move outwards, so as to adjust the distance between multiple soil-repairing knives 8602 and soil-crushing knives 8601 to be the same as the aperture of the opening, playing a role in adjusting the tool size; The setting of the inner rod of the ring plate 12 will also drive the ring plate 12 to rotate. When the ring plate 12 rotates, it drives multiple air-extracting fan blocks 93 to rotate. When multiple air-extracting fan blocks 93 rotate, airflows are generated. Since the inner side of the air-extracting fan block 93 is a curved-arc surface fan blade and the outer side is a flat surface, when airflows are generated, air can be drawn in from the outside. Thus, when performing the opening operation on the concrete protection door, the air-extracting fan blocks 93 rotate continuously to perform air-extracting operations on the opening, so as to draw the dust generated by the opening into the ring shell 5. When the dust enters the ring shell 5, the water injector 9 injects water into the sprayer 91 through the water flow pipe 92. The water injector 9 sprays out the injected water in a mist. Driven by the wind generated by the air-extracting fan blocks 93, the water mist sprayed by the sprayer 91 will come into contact with the dust drawn in by the air-extracting fan blocks 93, thereby eliminating the dust generated by the opening, playing a role in removing smoke; When the water mist is sprayed by the sprayer 91, driven by the wind generated by the air-extracting fan blocks 93, the water mist will be blown onto the water-sliding plate. Driven by the gas, the drawn-in dust will also be blown onto the water-sliding plate. When the dust comes into contact with the water on the water-sliding plate, the water will cool the high-temperature flue gas and absorb the particulate matter in the flue gas, thereby reducing the flue gas temperature and reducing the diffusion of harmful substances, thus achieving the effect of removing smoke. The precipitated impurities will be adsorbed on the water-sliding plate. When there is too much on the water-sliding plate, by pouring water from the cleaning plate water box 6, the water will flow down from the top of the water-sliding plate along the water-sliding port 61 and finally flow out from the leakage trough at the bottom of the ring shell 5, thereby realizing the cleaning of the water-sliding plate; When the slag collecting box 4 on one end of the telescopic rod 42 contacts one side of the concrete protection door, the operation of the positioning motor 31 is stopped. At this time, the two slag collecting boxes 4 are respectively placed on both sides of the opening of the concrete protection door, so that when the expansion unit performs the opening operation, the two slag collecting boxes 4 can receive the soil residue from the opening to prevent the soil residue from falling to the ground and needing to be cleaned later. When the soil residue in the two slag collecting boxes 4 is full, water flow will be generated inside one of the slag collecting boxes 4 when collecting the residue. By pushing the telescopic rod 42 to rotate on the sliding shaft 32, the soil residue in the dry slag collecting box 4 can be poured out, and by pulling the drawer 41 out of the wet slag collecting box 4, the soil residue collected inside can be cleared.
