Description
Technical Field
[0001] The utility model relates to the technical field of cast-in-place pile construction, and more specifically, to a cleaning device for cast-in-place pile heads. Background Art
[0002] Cast-in-place piles are made by drilling holes with a drilling machine and pouring concrete in the holes. They can form a tight bond with the soil or rock and effectively withstand the loads transferred from the superstructure. They can withstand vertical loads, horizontal loads, and seismic forces, etc., to ensure the stability and safety of buildings or structures.
[0003] Since the concrete strength on the bored pile is not good, in order to ensure the strength of the concrete, the elevation of the top of the bored pile will generally exceed the elevation of the designed pile top, thus forming the bored pile head. At present, when cleaning the bored pile head, a pile breaker is usually used for cleaning. When the pile breaker breaks the pile head, the force generated by the pile breaker drill bit will crush the concrete and leave the steel bars. When the concrete is crushed, a large amount of large-particle dust will be generated, which will affect the construction environment and the health of the construction workers. Therefore, it needs to be improved and optimized. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] like Figures 1 to 6As shown, the utility model provides a cleaning device for the pile head of a cast-in-place pile, comprising a fixed bracket 1, a connecting plate 1 2 is fixedly installed on the left side of the fixed bracket 1, a connecting plate 2 3 is fixedly installed on the right side of the fixed bracket 1, an oil cylinder 4 is fixedly installed at the rear of the fixed bracket 1, a crushing head 5 is arranged at the front end of the oil cylinder 4, and the crushing head 5 is located inside the fixed bracket 1;
[0025] Telescopic grooves 6 are fixedly provided on the left and right sides inside the fixed bracket 1, a fixed plate 7 is fixedly installed inside the telescopic groove 6, a sensing block 8 is movably installed inside the telescopic groove 6, one end of the sensing block 8 is fixedly connected to the connecting rod 9, one end of the connecting rod 9 penetrates into the sealing bin 11 and is fixedly connected to the sealing pressure block 12, one end of the sensing block 8 is elastically connected to the fixed plate 7 by a spring 10, the sensing block 8 and the crushing head 5 are in conflict with each other, a water inlet bin 14 is fixedly provided at the rear of the sealing bin 11, the sealing bin 11 and the water inlet bin 14 are connected to each other, and a water storage bin 13 is fixedly provided at the rear of the water inlet bin 14.
[0026] When cleaning the pile head of the bored pile, the staff first fills the water storage tank 13 with water through the water inlet 18, and then the staff can start the oil cylinder 4 to detect the operation of the crushing head 5. When the crushing head 5 moves outward, the outer wall of the crushing head 5 will squeeze the sensing block 8. At this time, the sensing block 8 moves toward the inside of the telescopic slot 6, and through the sensing block 8, the sealing pressure block 12 is displaced along the inside of the sealing bin 11. At this time, the pressure inside the sealing bin 11 increases, and the pressure inside the sealing bin 11 will push the sealing cover 22, so that the sealing cover 22 is displaced along the guide groove 20, and at this time the spring 3 21 is compressed, and the air inside the sealing bin 11 passes through the water outlet bin 19 and is discharged by the mist nozzle 24. When ensuring that the crushing head 5 can operate normally, the staff resets the crushing head 5 to complete the detection of the crushing head 5 before work. When the crushing head 5 is reset, due to the elastic potential energy of the spring 10, the sensing block 8 returns to its original position. At this time, the sealing pressure block 12 is also reset, and the sealing pressure block 12 is restored. When the pile is broken, the water source in the sealed chamber 11 will be squeezed by the sealing cover 22, and the water will enter the water pipe 23 through the water outlet chamber 19, and be sprayed out by the mist nozzle 24 for dust reduction. After the pile breaking operation is completed, the staff will reset the crushing head 5. At this time, through the elastic potential energy of the spring four 27, the cleaning plate 26 will always conflict with the outer wall of the crushing head 5, and the cleaning plate 26 will remove the dust and impurities remaining when the crushing head 5 breaks the pile, so as to prevent dust from entering the interior of the oil cylinder 4.
[0027] The crushing head 5 is driven by the oil cylinder 4 to clean the pile head. When the crushing head 5 is extended, the sealing block 12 pushes the water inside the sealing chamber 11 through the water outlet chamber 19 and is sprayed out by the mist nozzle 24. When the crushing head 5 is stored, the sealing block 12 is pulled to make the water inside the water storage chamber 13 enter the sealing chamber 11 to prepare for the next dust reduction. Compared with traditional piles, the device senses the operation of the crushing head 5 through the sensing block 8, so that when the crushing head 5 is performing the cleaning operation, the mist nozzle 24 sprays water to reduce dust, and when the crushing head 5 is performing the resetting operation, the water source is filled, which effectively reduces the dust content in the construction market and ensures the health of the staff.
[0028] Among them, a storage bin 25 is opened inside the fixed bracket 1, and a cleaning plate 26 is movably installed inside the storage bin 25. There are four groups of cleaning plates 26, and the four groups of cleaning plates 26 and the inner wall of the storage bin 25 are elastically connected by spring four 27, and the cleaning plates 26 and the outer wall of the crushing head 5 are in conflict with each other.
[0029] After the pile breaking operation is completed, the staff will reset the crushing head 5. At this time, through the elastic potential energy of the spring 27, the cleaning plate 26 will always contact the outer wall of the crushing head 5. The cleaning plate 26 will remove the dust and impurities remaining when the crushing head 5 breaks the pile, preventing dust from entering the interior of the oil cylinder 4.
[0030] Through the elastic potential energy of the spring four 27, the cleaning plate 26 will always contact the outer wall of the crushing head 5. When the crushing head 5 is recovered, the cleaning plate 26 will remove the dust and impurities remaining when the crushing head 5 breaks the pile, thereby preventing the dust from entering the interior of the oil cylinder 4. Compared with the traditional device, the device avoids the residue of dust and debris through the provision of the cleaning plate 26, thereby extending the service life of the oil cylinder 4 and the crushing head 5 and reducing the maintenance burden.
[0031] Among them, the inside of the water inlet bin 14 is fixedly installed with a guide groove 15, there are two groups of guide grooves 15, and they are located on the left and right sides of the inside of the water inlet bin 14, and the inside of the two groups of guide grooves 15 is movably installed with a sealing cover 16, the sealing cover 16 and the inner wall of the water inlet bin 14 are elastically connected by a spring 2 17, there are two groups of springs 17, and they are elastically arranged inside the guide groove 15, and the sealing cover 16 seals the water storage bin 13 and the water inlet bin 14.
[0032] When the crushing head 5 is reset, the sealing cover 16 will be pulled to move the sealing cover 16 along the guide groove 15. At this time, the water source inside the water storage tank 13 will enter the sealing tank 11 through the water inlet tank 14 to prepare for the dust reduction operation.
[0033] Among them, a water outlet bin 19 is fixedly opened on the side of the sealing bin 11, and a guide groove 20 is fixedly installed inside the water outlet bin 19. There are two groups of guide grooves 20, which are located on the front and rear sides of the water outlet bin 19. Sealing covers 22 are movably installed inside the two groups of guide grooves 20. The sealing covers 22 and the inner wall of the water outlet bin 19 are elastically connected by springs 3 21. There are two groups of springs 3 21, which are elastically arranged inside the guide grooves 20. The sealing covers 22 seal the sealing bin 11 and the water outlet bin 19.
[0034] While the crushing head 5 is breaking the pile, the water source inside the sealing chamber 11 will squeeze the sealing cover 22, causing the sealing cover 22 to move along the guide groove 20, and at this time the spring 3 21 is compressed.
[0035] A water pipe 23 is fixedly installed on the top outer wall of the fixed bracket 1 , the water pipe 23 and the water outlet bin 19 are connected to each other, and a mist nozzle 24 is fixedly arranged on the top of the water pipe 23 .

[0039] The staff can replenish the water source inside the water storage tank 13 through the water inlet 18.
[0040] The working principle and use process of this utility model:
[0041] When cleaning the pile head of the bored pile, the staff first fills the water storage tank 13 with water through the water inlet 18, and then the staff can start the oil cylinder 4 to detect the operation of the crushing head 5. When the crushing head 5 moves outward, the outer wall of the crushing head 5 will squeeze the sensing block 8. At this time, the sensing block 8 moves toward the inside of the telescopic slot 6, and through the sensing block 8, the sealing pressure block 12 is displaced along the inside of the sealing bin 11. At this time, the pressure inside the sealing bin 11 increases, and the pressure inside the sealing bin 11 will push the sealing cover 22, so that the sealing cover 22 is displaced along the guide groove 20, and at this time the spring 3 21 is compressed, and the air inside the sealing bin 11 passes through the water outlet bin 19 and is discharged by the mist nozzle 24. When ensuring that the crushing head 5 can operate normally, the staff resets the crushing head 5 to complete the detection of the crushing head 5 before work. When the crushing head 5 is reset, due to the elastic potential energy of the spring 10, the sensing block 8 returns to its original position. At this time, the sealing pressure block 12 is also reset, and the sealing pressure block 12 is restored. When the pile is broken, the water source in the sealed chamber 11 will be squeezed by the sealing cover 22, and the water will enter the water pipe 23 through the water outlet chamber 19, and be sprayed out by the mist nozzle 24 for dust reduction. After the pile breaking operation is completed, the staff will reset the crushing head 5. At this time, through the elastic potential energy of the spring four 27, the cleaning plate 26 will always conflict with the outer wall of the crushing head 5, and the cleaning plate 26 will remove the dust and impurities remaining when the crushing head 5 breaks the pile, so as to prevent dust from entering the interior of the oil cylinder 4.
