Description

Technical Field

[0001] The present application relates to the technical field of pipe pile driving, and in particular to a concrete pipe pile driving device. Background Art

[0002] Pipe pile excavation refers to the operation of excavating the interior to remove a certain layer of soil or filling materials during the construction of pipe piles.

[0003] An existing patent (publication number: CN215759024U) discloses a device for driving concrete pipe piles in construction projects. The device includes a motor and a drill rod, which are fixedly connected to the motor. The device also features a frame located atop the drill rod and rotatably connected to it. The frame is rotatably connected to an adjustment member, which is hingedly connected to a connecting member, which is slidably connected to a stopper. The beneficial effects of this device include reduced labor, improved work efficiency, and enhanced construction safety.

[0004] During the use of the above device, labor is reduced, work efficiency is improved, and construction operation safety is high. After the pile is driven, the drill rod (surface is often covered with a large amount of mud and debris. These attachments are not only difficult to clean, but also have an adverse effect on the subsequent pile driving operation. On the one hand, the mud and debris attached to the surface of the drill rod increase the weight and resistance of the drill rod, making it difficult to move the lifting plate up and down, thereby affecting construction efficiency; on the other hand, the attachments may also cause wear and corrosion to the surface of the drill rod, shortening its service life. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the present application provides a concrete pipe pile driving device, which has the advantages of being easy to clean and solves the problems raised in the background technology.

[0006] To achieve the above-mentioned objectives, the present application provides the following technical solution: a concrete pipe pile driving device, comprising two mobile frames, wherein the top ends of the two mobile frames are slidably connected to a same lifting plate, the lifting plate is internally rotatably connected to a drill shaft, the outer surface of the drill shaft is fixedly connected to a blade, and the bottom end of the drill shaft is fixedly connected to a drill bit;

[0007] A group of supporting ribs are fixedly connected to the bottom ends of the two movable frames, and a same cleaning ring is fixedly connected between the two groups of supporting ribs. The inner wall of the cleaning ring is fixedly connected to multiple high-pressure nozzles, and the bottom end of the drill shaft is located inside the cleaning ring.

[0008] Through the above scheme, the drill shaft, blades and drill bit can be automatically cleaned immediately after the pile driving operation is completed. The water flow sprayed by the high-pressure nozzle can effectively wash away the dirt and debris on the surface of the drill rod, avoiding the extra weight and resistance of the attachments to the drill rod, ensuring the smooth up and down movement of the lifting plate, thereby improving construction efficiency. At the same time, the cleaning work also extends the service life of the drill rod and reduces the frequency of replacement due to wear and corrosion. The cleaning ring not only has a cleaning function, but also can play a protective role in the soil splashing during the pile driving process. When the drill bit penetrates deep into the pipe pile for pile driving, the generated soil and debris are easy to splash, and the setting of the cleaning ring can effectively block these splashes to prevent them from polluting the construction environment or injuring construction workers. The mobile frame can be firmly fixed to the ground through the design of fixed plates and fixed nails, avoiding safety hazards caused by the self-movement of the mobile frame during the pile driving process.

[0009] Furthermore, a threaded rod is rotatably connected between the inner top wall and the inner bottom wall of each movable frame, and the lifting plate is threadedly connected to the two threaded rods.

[0010] Through the above solution, the purpose of moving the lifting plate up and down can be achieved by setting the threaded rod.

[0011] Furthermore, the two movable frames are fixedly connected to each other at their bottom ends with fixed plates on their sides that are away from each other, and each of the fixed plates has a fixing nail slidably inserted into its interior.

[0012] Through the above solution, by providing the fixing nails, the purpose of fixing the movable frame can be achieved, thereby preventing the movable frame from moving on its own during the pile excavation process.

[0013] Furthermore, the outer surface of the cleaning ring is fixedly connected to a connecting pipe.

[0014] Through the above solution, the provision of the connecting pipe facilitates the user to connect with the external water supply pipe.

[0015] Furthermore, a U-shaped frame is fixedly connected to the upper surface of the lifting plate, a first motor is fixedly installed inside the U-shaped frame, and an output end of the first motor is fixedly connected to the top end of the drill shaft.

[0016] Through the above solution, the first motor is provided to provide power for the rotation of the rotating shaft.

[0017] Furthermore, a second motor is installed on the top of each of the two movable frames, and the output ends of the two second motors are fixedly connected to the threaded rods adjacent thereto.

[0018] Through the above solution, by setting the second motor, it is possible to provide power for the rotation of the drill shaft.

[0019] Furthermore, a control host is installed on the front side of the bottom end of the movable frame on the left side, and the first motor and the second motor are both electrically connected to the control host.

[0020] Through the above solution, the purpose of controlling the first motor and the second motor can be achieved by controlling the settings of the host.

[0021] Furthermore, the drill shaft, blades and drill bit are all made of wear-resistant alloy material.

[0022] Through the above solution, the pile driving device has good wear resistance and corrosion resistance, can maintain a good working state during long-term work, and extends the service life of the pile driving device.

[0023] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0024] The device can automatically clean the drill shaft, blades and drill bit immediately after the pile driving operation is completed. The water flow sprayed by the high-pressure nozzle can effectively wash away the dirt and debris on the surface of the drill rod, avoiding the extra weight and resistance of the attachments on the drill rod, ensuring the smooth up and down movement of the lifting plate, thereby improving construction efficiency. At the same time, the cleaning work also extends the service life of the drill rod and reduces the replacement frequency due to wear and corrosion. The cleaning ring not only has a cleaning function, but also can play a protective role in the soil splashing during the pile driving process. When the drill bit penetrates deep into the pipe pile for pile driving, the generated dirt and debris are easy to splash, and the setting of the cleaning ring can effectively block these splashes to prevent them from polluting the construction environment or injuring construction workers. The mobile frame can be firmly fixed to the ground through the design of the fixed plate and the fixed nails, avoiding the safety hazard caused by the self-movement of the mobile frame during the pile driving process.

Through the arrangement of the threaded rod 9, the up and down movement of the lifting plate 2 can be achieved. The drill shaft 3, blade 4 and drill bit 5 are all made of wear-resistant alloy material with good wear resistance and corrosion resistance. They can maintain a good working condition during long-term work, thereby extending the service life of the pile-driving device.

[0033] See also Figure 1 、 Figure 2 and Figure 4 The bottom ends of the two mobile frames 1 are fixedly connected to a group of supporting ribs 6, and the same cleaning ring 7 is fixedly connected between the two groups of supporting ribs 6. The inner wall of the cleaning ring 7 is fixedly connected with multiple high-pressure nozzles 8. The bottom end of the drill shaft 3 is located inside the cleaning ring 7. Through the setting of the high-pressure nozzle 8, the purpose of cleaning the blade 4 can be achieved. The outer surface of the cleaning ring 7 is fixedly connected with a connecting pipe 12. The setting of the connecting pipe 12 facilitates the user to connect to the external water supply pipe.

[0034] See also Figure 1 、 Figure 2 and Figure 3The two movable frames 1 are fixedly connected to a fixed plate 10 on the sides away from each other at the bottom ends thereof, and a fixing nail 11 is slidably inserted into the interior of each fixing plate 10. By setting the fixing nail 11, the movable frame 1 can be fixed to avoid the movable frame 1 from moving on its own during the pile-pulling process.

[0035] See also Figure 1 、 Figure 2 and Figure 3 The upper surface of the lifting plate 2 is fixedly connected to a U-shaped frame 13, and a first motor 14 is fixedly installed inside the U-shaped frame 13. The output end of the first motor 14 is fixedly connected to the top of the drill shaft 3. Through the setting of the first motor 14, it can provide power for the rotation of the rotating shaft. The top of the two mobile frames 1 are both installed with a second motor 15, and the output ends of the two second motors 15 are fixedly connected to the threaded rod 9 close to them. Through the setting of the second motor 15, it can provide power for the rotation of the drill shaft 3. A control host 16 is installed on the front of the bottom end of the mobile frame 1 on the left. The first motor 14 and the second motor 15 are both electrically connected to the control host 16. Through the setting of the control host 16, the purpose of controlling the first motor 14 and the second motor 15 can be achieved.

[0036] A concrete pipe pile driving device in this embodiment can automatically clean the drill shaft 3, blades 4 and drill bit 5 immediately after the pile driving operation is completed. The water flow sprayed by the high-pressure nozzle 8 can effectively wash away the dirt and debris on the surface of the drill rod, avoiding the additional weight and resistance of the attachments on the drill rod, ensuring the smooth up and down movement of the lifting plate 2, thereby improving construction efficiency. At the same time, the cleaning work also extends the service life of the drill rod and reduces the replacement frequency due to wear and corrosion. The cleaning ring 7 not only has a cleaning function, but also plays a role in protecting the pile from splashing. When the drill bit 5 penetrates deep into the pipe pile to drive the pile, the generated dirt and debris are easy to splash, and the setting of the cleaning ring 7 can effectively block these splashes, preventing them from polluting the construction environment or injuring construction workers. The mobile frame 1 can be firmly fixed to the ground through the design of the fixing plate 10 and the fixing nails 11, avoiding the safety hazards caused by the self-movement of the mobile frame 1 during the pile driving process.

[0037] The working principle of the above embodiment is as follows: first, the two mobile frames 1 are firmly fixed to the ground by the fixing plates 10 and the fixing nails 11 to ensure stability during the pile-digging process. Then, the user connects the external water supply pipe to the cleaning ring 7 through the connecting pipe 12 to prepare for the subsequent cleaning work. Next, the control host 16 is started, and the control host 16 sends instructions to the first motor 14 and the second motor 15. After receiving the instructions, the first motor 14 starts to work, and its output end drives the drill shaft 3 to rotate inside the lifting plate 2. At the same time, the output end of the second motor 15 is connected to the threaded rod 9, driving the threaded rod 9 to rotate, and then drives the lifting plate 2 up and down through the threaded connection. In this way, the drill shaft 3, the blade 4 and the drill bit 5 are driven by the lifting plate 2 to penetrate into the concrete pipe pile to perform pile-digging operations. During the piling process, the rotation of the drill bit 5 and the stirring of the blades 4 will generate a large amount of dirt and debris. At this time, the setting of the cleaning ring 7 plays a key role. The cleaning ring 7 can not only effectively block the flying dirt and debris to prevent them from polluting the construction environment or injuring the construction workers, but also automatically clean the drill shaft 3, blades 4 and drill bit 5 immediately after the piling operation is completed through the high-pressure nozzle 8 fixedly connected to its inner wall. In order to clean, the user only needs to connect the external water supply pipe to the cleaning ring 7 through the connecting pipe 12. When the high-pressure nozzle 8 receives the water flow, it will immediately spray out high-pressure water to flush away the dirt and debris on the surface of the drill rod. This step not only reduces the weight and resistance of the drill rod, ensures the smooth up and down movement of the lifting plate 2, but also extends the service life of the drill rod and reduces the replacement frequency due to wear and corrosion.
