Description

Technical Field

[0001] This utility model relates to the field of building technology, and in particular to a building foundation pile demolition device. Background Technology

[0002] Pile foundation removal refers to the process of removing existing pile foundations during the demolition, reconstruction, or alteration of a building's foundation. This process requires selecting an appropriate removal method based on the type of pile foundation (e.g., precast piles, cast-in-place piles), geological conditions, surrounding environment, and the specific needs of the project.

[0003] In existing cutting methods, pile foundations are broken up, but a lot of dust is generated during the breaking process, which needs to be cleaned up. Currently, this is often done manually by watering, which is a waste of manpower. Similarly, the breaking of pile foundations is done by workers, which is also a waste of manpower. Utility Model Content

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a building foundation pile demolition device, comprising: a base plate, a water tank fixedly connected to the top of the outer surface of the base plate, a water pump fixedly connected to the top of the outer surface of the base plate, the input end of the water pump being connected to the outer surface of the water tank via a pipe, a telescopic hose fixedly connected to the output end of the water pump, a spray head fixedly connected to one end of the telescopic hose, two support rods fixedly connected to the top of the outer surface of the base plate, a movable block movably sleeved on the outer surface of the two support rods, and a fixing strip fixedly connected to the top of the outer surface of the two support rods.

[0005] The technical effect of adopting the above-mentioned further solution is as follows: the water pump is started by an external power source to extract water from the inside of the water tank through the pipe. After extraction, the water is transported to the inside of the spray head through a telescopic hose. The spray head sprays the water out, which reduces the dust of the drill bit during spraying.

[0006] In a preferred embodiment, two hydraulic cylinders are fixedly connected to the bottom of the outer surface of the fixing strip, and the bottom ends of the two hydraulic cylinders are fixedly connected to the outer surface of the moving block. A sliding rod one is fixedly connected inside the moving block, and a sliding rod two is fixedly connected inside the moving block. A slider is movably sleeved on the outer surface of the sliding rod one and the sliding rod two, and an electric push rod one is fixedly connected to the outer surface of the moving block.

[0007] The technical effect of adopting the above-mentioned further solution is that by starting the electric push rod one with an external power source to push the slider to slide on the outer surface of the sliding rod two and the sliding rod one, the drill bit can move laterally during the breaking process, thereby increasing the breaking range of the drill bit.

[0008] In a preferred embodiment, one end of the electric push rod is fixedly connected to the outer surface of the slider, the outer surface of the slider is fixedly connected to the electric push rod, one end of the electric push rod is fixedly connected to the fixing block, the bottom of the outer surface of the fixing block is fixedly connected to the damper, the bottom of the outer surface of the fixing block is fixedly connected to the spring, and the bottom of the outer surface of the damper is fixedly connected to the connecting block.

[0009] The technical effect of adopting the above-mentioned further solution is as follows: the electric push rod two is started by an external power source, and the electric push rod two pushes the connecting block to move laterally. At this time, the drill bit on the connecting block can move laterally, and the area is wider when the drill bit is breaking. At the same time, a large vibration will occur when the drill bit is breaking. The reciprocating extension and retraction is achieved by the cooperation of the spring and the damper, which reduces the vibration caused by the drill bit and reduces the shaking of the entire device when breaking.

[0010] In a preferred embodiment, a motor is fixedly connected to the top of the outer surface of the connecting block, and a drill bit is fixedly connected to the output end of the motor. The water spray head is located directly above the drill bit. Threaded rods are movably embedded in the outer surface of the base plate near its periphery. The bottom ends of multiple threaded rods are rotatably connected to a plate through bearings. Multiple threaded rods are movably embedded inside the multiple plate. The bottom ends of multiple threaded rods are rotatably connected to a support plate through bearings.

[0011] The technical effect of adopting the above-mentioned further solution is as follows: the motor is started by an external power source, the motor drives the drill bit to rotate, the drill bit breaks the pile foundation, and at this time the hydraulic cylinder is started by an external power source, the two hydraulic cylinders push the moving block to slide on the surface of the support rod, and the height of the drill bit can be adjusted.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In use, when breaking the drill bit, the water pump is started by an external power source to draw water out of the tank through a pipe. After being drawn out, the water is transported to the inside of the spray head through a telescopic hose. The spray head sprays the water out, which reduces the dust on the drill bit during spraying.

[0014] 2. When using this utility model, the device is moved to the area where the pile needs to be broken, and then the first threaded rod at the bottom is rotated. The first threaded rod moves up and down inside the base plate. At this time, the height of each plate can be adjusted. Then, each second threaded rod is rotated to adjust the height of the support plate. This can adapt to the uneven terrain of the building ground and make the whole device horizontal.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Please see Figures 1 to 4This utility model provides a building foundation pile demolition device, including: a base plate 101, a water tank 118 fixedly connected to the top of the outer surface of the base plate 101, a water pump 119 fixedly connected to the top of the outer surface of the base plate 101, the input end of the water pump 119 being connected to the outer surface of the water tank 118 through a pipe, the output end of the water pump 119 being fixedly connected to a telescopic hose 120, one end of the telescopic hose 120 being fixedly connected to a spray head 121, two support rods 102 fixedly connected to the top of the outer surface of the base plate 101, a movable block 103 movably sleeved on the outer surface of the two support rods 102, and a fixing strip 104 fixedly connected to the top of the outer surface of the two support rods 102. The water pump 119 is started by an external power source to extract water from the inside of the water tank 118 through the pipe. After extraction, the water is transported to the inside of the spray head 121 through the telescopic hose 120. The spray head 121 sprays the water out, reducing dust on the drill bit 117 during spraying.

[0023] like Figures 1 to 4 As shown, two hydraulic cylinders 105 are fixedly connected to the bottom of the outer surface of the fixed strip 104. The bottom ends of the two hydraulic cylinders 105 are fixedly connected to the outer surface of the moving block 103. A sliding rod 107 is fixedly connected inside the moving block 103. A sliding rod 108 is fixedly connected inside the moving block 103. A slider 110 is movably sleeved on the outer surface of the sliding rod 107 and the sliding rod 108. An electric push rod 109 is fixedly connected to the outer surface of the moving block 103. By starting the electric push rod 109 with an external power source, the slider 110 can be pushed to slide on the outer surface of the sliding rod 108 and the sliding rod 107, which can make the drill bit 117 move laterally during breaking, increasing the breaking range of the drill bit 117.

[0024] like Figures 1 to 4 As shown, one end of the electric push rod 109 is fixedly connected to the outer surface of the slider 110. The outer surface of the slider 110 is fixedly connected to the electric push rod 111. One end of the electric push rod 111 is fixedly connected to the fixing block 112. The bottom of the outer surface of the fixing block 112 is fixedly connected to the damper 114. The bottom of the outer surface of the fixing block 112 is fixedly connected to the spring 113. The bottom of the outer surface of the damper 114 is fixedly connected to the connecting block 115. When the electric push rod 111 is started by an external power source, the electric push rod 111 pushes the connecting block 115 to move laterally. At this time, the drill bit 117 on the connecting block 115 can move laterally. When the drill bit 117 breaks, the area is larger. At the same time, when the drill bit 117 breaks, there will be a large vibration. The reciprocating extension and retraction is achieved by the cooperation of the spring 113 and the damper 114, which reduces the vibration caused by the drill bit 117 and reduces the shaking of the entire device when breaking.

[0025] like Figures 1 to 4As shown, a motor 116 is fixedly connected to the top of the outer surface of the connecting block 115. A drill bit 117 is fixedly connected to the output end of the motor 116. A water spray head 121 is located directly above the drill bit 117. Threaded rods 122 are movably embedded in the outer surface of the base plate 101 near its periphery. The bottom ends of multiple threaded rods 122 are rotatably connected to a plate 123 via bearings. Multiple threaded rods 124 are movably embedded inside the multiple plate 123. The bottom ends of multiple threaded rods 124 are rotatably connected to a support plate 125 via bearings. The motor 116 is started by an external power source, which drives the drill bit 117 to rotate. The drill bit 117 breaks the pile foundation. At this time, the hydraulic cylinder 105 is started by an external power source. The two hydraulic cylinders 105 push the moving block 103 to slide on the surface of the support rod 102. At this time, the height of the drill bit 117 can be adjusted.

[0026] Working principle: The device is moved to the area where pile breaking is required. Then, the threaded rod 122 at the bottom is rotated, causing it to move up and down inside the base plate 101. The height of each plate 123 can be adjusted at this time. Then, each threaded rod 124 is rotated, allowing the height of the support plate 125 to be adjusted. This adapts to uneven terrain, ensuring the entire device is horizontal and highly efficient. An external power source activates the electric push rod 109, pushing the slider 110 to slide on the outer surfaces of the sliding rod 108 and sliding rod 107, allowing the drill bit 117 to move laterally during breaking. An external power source activates the motor 116, which drives the drill bit 117 to rotate, breaking the pile. At this time, an external power source activates the hydraulic cylinders 105, which push the moving block 103 on the support rod 101. Surface 2 slides, at which time the height of drill bit 117 can be adjusted. Electric push rod 2 111 is started by external power. Electric push rod 2 111 pushes connecting block 115 to move laterally. At this time, drill bit 117 on connecting block 115 can move laterally, so the area of ​​the drill bit 117 is wider when it breaks. At the same time, the drill bit 117 will vibrate more when it breaks. The spring 113 and damper 114 work together to achieve reciprocating extension and retraction, reducing the vibration caused by drill bit 117 and reducing the shaking of the whole device when breaking. At the same time, when breaking, water pump 119 is started by external power to extract water from inside water tank 118 through pipe. After extraction, water is transported to the inside of spray head 121 through telescopic hose 120. Spray head 121 sprays water out, reducing dust on drill bit 117 when spraying.

[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
