Description

Technical Field

[0001] This invention relates to the field of building demolition equipment technology, and in particular to a demolition equipment for concrete structures of super high-rise buildings. Background Technology

[0002] With the acceleration of urbanization, the number of super high-rise buildings is increasing year by year, and their demolition has become a key part of urban renewal and building renovation. At present, the demolition of super high-rise buildings often adopts methods such as blasting, large-scale mechanical crushing, or manual demolition. These traditional methods generally have the following prominent problems: I. Although blasting demolition is highly efficient, it generates violent vibrations and noise, which can easily damage the surrounding building structures and underground pipelines, and is accompanied by a large amount of dust pollution, which has a significant impact on the environment. Second, large machinery such as hydraulic shears and hydraulic breakers are noisy during operation and are bulky, making it difficult to operate flexibly in the narrow spaces inside high-rise buildings, posing safety hazards. Third, manual demolition is slow and labor-intensive, and workers are exposed to dangerous high-altitude environments for long periods of time. In addition, the noise and dust generated during construction are difficult to control effectively, threatening the health of workers and affecting the lives of surrounding residents. Therefore, a device for demolishing concrete structures of super high-rise buildings is proposed. Summary of the Invention

[0003] In view of this, embodiments of the present invention provide a demolition device for concrete structures of super high-rise buildings to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

The output shaft of the second servo motor passes through the first rotating arm and is fixedly connected to one side of the second rotating arm. A mounting arm is rotatably connected to the inner wall of the distal end of the second rotating arm via a bearing. A third servo motor is fixedly connected to the outer wall of the second rotating arm. The output shaft of the third servo motor passes through the second rotating arm and is fixedly connected to one side of the mounting arm. A vibrator is fixedly connected to the upper surface of the mounting arm. A crushing rod is fixedly connected to the end of the vibrator. Sound insulation and dust reduction components are provided on the mounting arm and the vibrator.

[0005] In some embodiments, the sound insulation and dust suppression assembly includes a protective tube, a dust suppression mechanism, a ring column, a ring plate, several springs, a sound-absorbing layer, and a sound-insulating layer. The ring column is fixedly connected to one side of the mounting arm, and a breaking rod passes through the ring column. The ring plate is fixedly connected to the outer wall of the ring column, and one end of each of the several springs is uniformly fixedly connected to one side of the ring plate. The inner wall of the protective tube is slidably connected to the outer wall of the ring column, and the other ends of each of the springs are uniformly fixedly connected to one end of the protective tube. The sound-absorbing layer and the sound-insulating layer are both disposed inside the protective tube, and the outer wall of the sound-absorbing layer is attached to the inner wall of the sound-insulating layer. The dust suppression mechanism is respectively disposed on the mounting arm and the protective tube.

[0006] In some embodiments, the dust suppression mechanism includes a water tank, a corrugated pipe, a first pipe body, a ring pipe, a plurality of nozzles, a water pump, and a second pipe body. The water tank is fixedly connected to the lower surface of the mounting arm, and the water pump is fixedly connected to the inner bottom wall of the water tank. One end of the second pipe body penetrates the water tank and is fixedly connected to the outlet of the water pump. The ring pipe is embedded in the inner wall of the protective pipe, and a plurality of nozzles are arranged in a ring array, obliquely penetrating the ring pipe and fixedly connected. One end of the first pipe body sequentially penetrates the protective pipe and the ring pipe and is fixedly connected. One end of the corrugated pipe is connected to the first pipe body, and the other end is connected to the second pipe body.

[0007] In some embodiments, the inner wall of the protective tube is uniformly provided with grooves, and the outer wall of the annular column is uniformly fixedly connected with sliders, the outer wall of the sliders being slidably connected to the inner wall of the grooves.

[0008] In some embodiments, a rubber sealing gasket is fixedly connected to the inner wall of the protective tube, and the inner wall of the rubber sealing gasket is attached to the outer wall of the ring column.

[0009] In some embodiments, a rubber ring gasket is fixedly connected to the other end of the protective tube.

[0010] In some embodiments, the sound-absorbing layer is made of glass wool or sound-absorbing sponge.

[0011] The embodiments of the present invention have the following advantages due to the adoption of the above technical solutions: 1) This invention effectively blocks the transmission of noise generated by vibration and breakage through the combination structure of protective tube, sound-absorbing layer and sound-insulating layer, reducing noise pollution to the surrounding environment. At the same time, the built-in dust suppression mechanism continuously sprays water mist through ring nozzles, which can suppress the dust generated during the demolition process in real time, significantly improve the air quality of the working environment, and meet the environmental protection requirements of green building demolition.

[0012] 2) This invention uses a wirelessly controlled tracked vehicle as a mobile platform, which can be remotely controlled to enter the interior of super high-rise buildings. The rotating arm structure driven by multi-level servo motors can achieve multi-angle and multi-directional adjustment, so that the breaking rod can accurately reach the target demolition position, thereby effectively reducing the risk of high-altitude operation for operators. At the same time, it enhances the adaptability of the equipment in complex building spaces, and is especially suitable for demolition operations in narrow and irregular structures.

[0013] 3) By adopting the combined design of spring, slider and groove, the protective tube can adaptively expand and contract with the impact force of the crushing operation. This ensures that the crushing rod fits tightly with the working surface, and the spring buffer reduces the impact of mechanical vibration on the overall structure, thereby improving the stability and service life of the device. The rubber sealing gasket and rubber ring gasket further enhance the sound insulation and sealing effect, and prevent dust leakage.

[0014] 4) This invention enables rapid positioning and multi-degree-of-freedom adjustment of crushing components through multi-servo motor coordinated control, greatly simplifying the operation process; combined with the vibration crushing mechanism, it can carry out continuous and efficient crushing operations on building structures, significantly improving construction efficiency and shortening the construction period compared with traditional manual demolition methods.

[0021] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1-7 As shown, this embodiment of the invention provides a demolition device for a super high-rise building concrete structure, including a wirelessly controlled tracked vehicle 1. A circular housing 3 is fixedly connected to the upper surface of the wirelessly controlled tracked vehicle 1. A rotating frame 4 is rotatably connected to the upper surface of the circular housing 3 via bearings. A fourth servo motor 14 is fixedly connected to the inner wall of the circular housing 3. The output shaft of the fourth servo motor 14 passes through the circular housing 3 and is fixedly connected to the lower surface of the rotating frame 4. A first rotating arm 6 is rotatably connected to the inner wall of the rotating frame 4 via bearings. A first servo motor 5 is fixedly connected to the outer wall of the rotating frame 4. The output shaft of the first servo motor 5 passes through the rotating frame 4 and is fixed to one side of the first rotating arm 6. The distal end of the first rotating arm 6 is rotatably connected to a second rotating arm 8 via a bearing. A second servo motor 7 is fixedly connected to the outer wall of the first rotating arm 6. The output shaft of the second servo motor 7 passes through the first rotating arm 6 and is fixedly connected to one side of the second rotating arm 8. The inner wall of the distal end of the second rotating arm 8 is rotatably connected to a mounting arm 10 via a bearing. A third servo motor 9 is fixedly connected to the outer wall of the second rotating arm 8. The output shaft of the third servo motor 9 passes through the second rotating arm 8 and is fixedly connected to one side of the mounting arm 10. A vibrator 11 is fixedly connected to the upper surface of the mounting arm 10. A crushing rod 12 is fixedly connected to the output end of the vibrator 11. Sound insulation and dust reduction components 2 are provided on the mounting arm 10 and the vibrator 11.

[0023] In this embodiment, the sound insulation and dust reduction component 2 specifically includes a protective tube 20, a dust reduction mechanism 21, a ring column 22, a ring plate 23, several springs 24, a sound-absorbing layer 25, and a sound-insulating layer 26. The ring column 22 is fixedly connected to one side of the mounting arm 10, and the breaking rod 12 passes through the ring column 22. The ring plate 23 is fixedly connected to the outer wall of the ring column 22, and one end of several springs 24 is uniformly fixedly connected to one side of the ring plate 23. The inner wall of the protective tube 20 is slidably connected to the outer wall of the ring column 22, and the other end of several springs 24 is uniformly fixedly connected to one end of the protective tube 20. The sound-absorbing layer 25 and the sound-insulating layer 26 are both disposed inside the protective tube 20, and the outer wall of the sound-absorbing layer 25 is attached to the inner wall of the sound-insulating layer 26. The dust reduction mechanism 21 is disposed on the mounting arm 10 and the protective tube 20 respectively. With the above settings, when the breaker rod 12 continues to demolish the internal structure of the building, the reaction force of the internal structure will push the rubber ring pad 13 and the protective tube 20 to move on the ring column 22. The protective tube 20 compresses the spring 24 to produce deformation. The protective tube 20, the ring column 22, the ring plate 23, the sound-absorbing layer 25 and the sound-insulating layer 26 can block the noise generated by the continuous operation of the breaker rod 12 to reduce noise transmission.

[0024] After the breaking rod 12 finishes its work, the elastic potential energy of the spring 24 will cause the protective tube 20, sound-absorbing layer 25, sound-insulating layer 26 and rubber ring pad 13 to reset, making it convenient to repeat the work.

[0025] In this embodiment, the dust suppression mechanism 21 specifically includes a water tank 210, a corrugated pipe 211, a first pipe body 212, a ring pipe 213, several nozzles 214, a water pump 215, and a second pipe body 216. The water tank 210 is fixedly connected to the lower surface of the mounting arm 10, and the water pump 215 is fixedly connected to the inner bottom wall of the water tank 210. One end of the second pipe body 216 penetrates the water tank 210 and is fixedly connected to the outlet of the water pump 215. The ring pipe 213 is embedded in the inner wall of the protective pipe 20. Several nozzles 214 are arranged in a ring array and obliquely penetrate the ring pipe 213 and are fixedly connected. One end of the first pipe body 212 penetrates the protective pipe 20 and the ring pipe 213 in sequence and is fixedly connected. One end of the corrugated pipe 211 is connected to the first pipe body, and the other end is connected to the second pipe body 216. With the above settings, the water pump 215 draws water from the water tank 210 into the second pipe 216. The water in the second pipe 216 is transmitted to the ring pipe 213 through the corrugated pipe 211 and the first pipe 212. The water in the ring pipe 213 is sprayed out through several nozzles 214 to suppress the dust generated during the dismantling of the breaker rod 12.

[0026] In this embodiment, specifically, the inner wall of the protective tube 20 is uniformly provided with sliding grooves 15, and the outer wall of the annular column 22 is uniformly fixedly connected with sliders 16, the outer wall of the sliders 16 being slidably connected to the inner wall of the sliding grooves 15. With this arrangement, the sliders 16 slide within the sliding grooves 15, which can both assist the movement of the protective tube 20 and stabilize the position of the protective tube 20.

[0027] In this embodiment, specifically, a rubber sealing gasket 17 is fixedly connected to the inner wall of the protective tube 20, and the inner wall of the rubber sealing gasket 17 is attached to the outer wall of the ring post 22. The rubber sealing gasket 17 is used to enhance the sealing between the protective tube 20 and the ring post 22, thereby further reducing the diffusion of noise.

[0028] In this embodiment, specifically, a rubber ring gasket 13 is fixedly connected to the other end of the protective pipe 20. The rubber ring gasket 13 fits tightly against the building surface, further reducing noise leakage.

[0029] In this embodiment, the sound-absorbing layer 25 is specifically made of glass wool or sound-absorbing sponge.

[0030] When the invention is in operation: relevant personnel remotely control the tracked vehicle 1 to perform climbing operations inside a super high-rise building via wireless control. Subsequently, the output shaft of the fourth servo motor 14 drives the rotating frame 4 to rotate, the output shaft of the first servo motor 5 drives the first rotating arm 6 to rotate back and forth, the output shaft of the second servo motor 7 drives the second rotating arm 8 to rotate up and down, and the output shaft of the third servo motor 9 drives the mounting arm 10 to rotate up and down, thereby enabling the vibrator 11, the crushing rod 12, and the sound insulation and dust reduction component 2 to adapt to multiple angles and improve the convenience of operation.

[0031] When the mounting arm 10 pushes the vibrator 11 and the breaker bar 12 to demolish the internal structure of the building, the protective pipe 20 drives the rubber ring pad 13 to fit tightly against the building surface. The water pump 215 draws water from the water tank 210 into the second pipe 216. The water in the second pipe 216 is transmitted to the ring pipe 213 through the corrugated pipe 211 and the first pipe 212. The water in the ring pipe 213 is sprayed out through several nozzles 214 to suppress the dust generated by the demolition of the breaker bar 12.

[0032] As the breaker rod 12 continues to demolish the internal structure of the building, the reaction force of the building structure will push the rubber ring pad 13 and the protective tube 20 to move on the ring column 22. The protective tube 20 compresses the spring 24 to produce deformation. The protective tube 20, the ring column 22, the ring plate 23, the sound-absorbing layer 25 and the sound-insulating layer 26 can block the noise generated by the continuous operation of the breaker rod 12 to reduce the noise transmission.

[0033] After the breaking rod 12 finishes its work, the elastic potential energy of the spring 24 will cause the protective tube 20, sound-absorbing layer 25, sound-insulating layer 26 and rubber ring pad 13 to reset, making it easy to repeat the operation.

[0034] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in the present invention, and these should all be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
