Description

Technical Field

[0001] This utility model relates to the field of pile excavation technology, specifically a concrete pile excavation device. Background Technology

[0002] In construction engineering, it is necessary to perform pile excavation on concrete pipes. Pile excavation refers to the process of excavating the space below the ground where reinforced concrete needs to be poured. Generally, piles with a diameter of more than one meter are excavated manually, while piles with a diameter of less than one meter are excavated mechanically. Mechanical excavation requires the use of pile excavation devices.

[0003] A search revealed that Chinese Patent Publication No. CN 220336818 U relates to a concrete pipe pile excavation device, comprising a base, two electric telescopic rods fixedly connected to the top of the base, the output ends of the two electric telescopic rods extending to the bottom of the base and fixedly connected to a movable plate, a hollow drilling rod rotatably connected to the bottom of the movable plate, the top of the hollow drilling rod extending above the movable plate. The advantages of this invention are that by setting a transmission rod and a transmission groove for transmission, during the drilling process, the transmission rod and the transmission groove maintain relative sliding and transmission, and the electric telescopic rod does not need to rotate with the output shaft of the drive motor. By placing the outer shell of the electric telescopic rod above the base, the length located below the base can be reduced, thereby lowering the center of gravity and increasing the stability of the device. Simultaneously, during the drilling process, a simple damper composed of a damper and a spring can be used to reduce vibration, greatly improving the stability of the drilling process and the service life of the device.

[0004] The pile-excavating device in the aforementioned patent still has certain shortcomings. In actual use, the existing concrete pipe pile excavating device is difficult to quickly clean up the soil excavated by the pile excavator. As a result, when the pile-excavating spiral sleeve is pulled upward, the soil accumulated at the wellhead can easily fall into the well, causing unnecessary blockage and affecting the normal pipe pile installation operation. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a concrete pipe pile excavation device, which solves the problem that existing concrete pipe pile excavation devices are difficult to quickly clean up the soil excavated by the pile excavator during actual use. As a result, when the auger is pulled upwards, the soil accumulated at the wellhead can easily fall into the well, causing unnecessary blockage and affecting the normal pipe pile installation operation.

[0006] This utility model provides the following technical solution: a concrete pipe pile excavation device, including a support and movement component, a drilling and lifting component is provided at the top of the support and movement component, and an excavation component is provided on the drilling and lifting component.

A drive motor is disposed at the top of the lifting connecting frame, and the drive shaft of the drive motor is fixedly connected to the bottom end of the lifting screw. A lifting sleeve is fitted on the lifting screw. Two side wall limiting slots are symmetrically opened on both sides of the lifting connecting frame, and two limiting connecting blocks are symmetrically arranged on both sides of the lifting sleeve. The limiting connecting blocks pass through the side wall limiting slots.

[0009] The pile-pulling assembly includes a connecting support plate fixedly connected to the side of the lifting screw sleeve. A servo motor is provided on the connecting support plate. A drive connecting sleeve is provided at the bottom end of the servo motor. The bottom end of the drive connecting sleeve passes through the connecting support plate. A pile-pulling drill rod is provided at the bottom of the drive connecting sleeve. A connecting stud is provided at the top end of the pile-pulling drill rod. The top end of the connecting stud is threaded into the drive connecting sleeve.

[0019] (1) This utility model is provided with a drilling and lifting component and a pile-pulling component on the supporting moving component. The supporting moving component is provided with a soil sampling hole. When carrying out deep pile-pulling operations, the shallow well to be drilled first needs to be fitted with a wellhead limiting pipe to effectively protect the well. The servo motor drives the pile-pulling drill rod to drive the spiral cutter to drill. The soil in the drilling process will be lifted upward by the rotation of the spiral cutter and discharged into the soil collection tank through the wellhead limiting pipe. This avoids the soil generated during the pile-pulling process from accumulating at the wellhead position and prevents soil from falling into the well and causing blockage. It is more convenient for users to carry out normal pile-pulling operations and subsequent concrete pipe pile pouring operations, making it more convenient for users to use.

[0030] The supporting movable component 1 includes a movable support base 101, a soil collection trough 102 is provided at the top of the movable support base 101, wheel mounting brackets 103 are evenly arranged around the bottom of the movable support base 101, movable wheels 104 are rotatably mounted on the wheel mounting brackets 103, and adjusting screws 105 are evenly inserted around the top of the movable support base 101, with the bottom of the adjusting screws 105 rotatably connected to the top of the wheel mounting brackets 103.

[0031] The drilling and lifting assembly 2 includes a lifting connecting frame 201 set at the top of the movable support base 101. A lifting screw 202 is threaded into the lifting connecting frame 201. The bottom end of the lifting screw 202 is rotatably connected to the top end of the movable support base 101. A drive motor 203 is set at the top end of the lifting connecting frame 201. The drive shaft of the drive motor 203 is fixedly connected to the bottom end of the lifting screw 202. A lifting screw sleeve 204 is sleeved on the lifting screw 202. Two side wall limiting slots 205 are symmetrically opened on both sides of the lifting connecting frame 201. Two limiting connecting blocks 206 are symmetrically arranged on both sides of the lifting screw sleeve 204. The limiting connecting blocks 206 penetrate the side wall limiting slots 205.

[0032] The pile-extraction assembly 3 includes a connecting support plate 301 fixedly connected to the side of the lifting screw sleeve 204. A servo motor 302 is provided on the connecting support plate 301. A drive connecting sleeve 303 is provided at the bottom end of the servo motor 302. The bottom end of the drive connecting sleeve 303 passes through the connecting support plate 301. A pile-extraction drill rod 304 is provided at the bottom of the drive connecting sleeve 303. A connecting stud 305 is provided at the top end of the pile-extraction drill rod 304. The top end of the connecting stud 305 is threaded into the drive connecting sleeve 303. A spiral cutter 306 is provided on the pile-extraction drill rod 304. A soil-boring drill hole 307 is opened on the movable support base 101. A wellhead limiting pipe 308 is inserted into the soil-boring drill hole 307. The bottom end of the wellhead limiting pipe 308 extends to the bottom of the movable support base 101.

[0033] Example 2: The difference between this example and Example 1 is that a rotating block is provided at the top of the adjusting screw 105.

[0034] This makes it more convenient for users to rotate the adjusting screw 105.

[0035] Example 3: The difference between this example and Example 1 is that the two sides of the lifting connecting frame 201 are connected to the movable support base 101 through the fixed plates.

[0036] Further enhance the connection stability between the connecting frame 201 and the movable support base 101.

[0037] Example 4: The difference between this example and Example 1 is that a baffle is provided on the side of the top end of the wellhead limiting pipe 308.

[0038] This ensures that the wellhead limiting pipe 308 is inserted through the soil extraction borehole 307 to prevent it from falling off.

[0039] In this embodiment, because existing concrete pipe pile excavation devices are difficult to quickly clean up the soil excavated by the pile excavator during actual use, the soil accumulated at the wellhead can easily fall into the well when the auger is pulled upwards, causing unnecessary blockage and affecting normal pipe pile installation operations.

[0040] In summary, during specific implementation, when a user needs to perform concrete pipe pile extraction operations, the user first needs to move the device to the pre-designated extraction position. Then, the user starts the drive motor 203, which drives the lifting screw 202 to rotate. The lifting screw 202 then drives the connecting support plate 301 to move upward through the lifting sleeve 204. The user then starts the servo motor 302 on the connecting support plate 301, which drives the extraction drill rod 304 to rotate through the drive connecting sleeve 303. The extraction drill rod 304 is equipped with a spiral cutter 306, which can drill and excavate the soil. First, a shallow groove is drilled out. Then, by pulling up the extraction drill rod 304, an upper wellhead limiting pipe 308 is inserted into the soil extraction hole 307, so that the wellhead limiting pipe 308 can be inserted and limited at the top of the groove.

[0041] By rotating the adjusting screw 105, the distance between the movable support base 101 and the ground is further reduced, allowing the wellhead limiting pipe 308 to be stably inserted into the drilling groove. The drive motor 203 and servo motor 302 are then restarted, causing the servo motor 302 to drive the pile-excavating drill rod 304 and the spiral cutter 306 to rotate and excavate the soil. At this time, the soil during the drilling process is conveyed upwards in a spiral shape by the spiral cutter 306, and the conveyed soil is discharged into the soil collection trough 102 through the top of the wellhead limiting pipe 308. This effectively prevents soil from accumulating at the wellhead during the pile-excavating process and prevents soil from falling into the well and causing blockages. This makes it easier for users to carry out normal pile-excavating operations and subsequent concrete pipe pile pouring operations, making it more convenient for users to use.
