[0043] like Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, the top of the single-head screw rod 107 movably passes through the top of the inner wall of the drill rig 101, and the top of the single-head screw rod 107 is installed with the output end of the first motor 106.

The inside of the drill rig 101 is slidably connected with a lifting plate 110, and the main verticality sensor 217 is installed on the front surface of the lifting plate 110, so that the main verticality sensor 217 can be driven to move under the action of the lifting plate 110.

[0044] like Figure 1 , Figure 3 , Figure 5 , Figure 6 and Figure 8 As shown, the bottom thread of the single-head screw rod 107 passes through the top of the lifting plate 110, the front surface of the drill frame 101 is in contact with the surface of the lifting plate 110, and a second motor 111 is installed on the top of the lifting plate 110. The integrated high-precision GPS 109 is located directly above the second motor 111, and a connecting rod 113 is installed at the output end of the second motor 111. With the cooperation of the connecting rod 113, the lifting plate 110 and the second motor 111, the drill bit 114 can be driven to rotate.

[0045] like Figure 1-Figure 8 As shown, the bottom of the second rectangular block 206, the bottom of the semicircular block 213 and the bottom of the two auxiliary blocks 211 are all in contact with the upper side of the connecting rod 113, and the top of the connecting rod 113 is rotatably connected to the inside of the through hole of the lifting plate 110 through a bearing, and a drill bit 114 is installed at the bottom of the connecting rod 113. A casing 115 is fixed on the front surface of the drilling frame 101 near the top position, and a visual sensor 112 is installed inside the surface groove of the casing 115, so that the drill bit 114 can be accurately moved to the drilling position with the cooperation of the controller 102, the integrated high-precision GPS 109, the visual sensor 112, the traction equipment, the hollow block 103, the two mounting blocks 104, the prepared hydraulic cylinder and the prepared pins.

[0046] like Figure 1-Figure 3 and Figure 5-Figure 8 As shown, the drill bit 114 is movably sleeved inside the casing 115, the two first electric cylinders 204, the two second electric cylinders 208 and the main verticality sensor 217 are all electrically connected to the controller 102, and the auxiliary verticality sensor 105, the first motor 106, the integrated high-precision GPS 109, the second motor 111 and the visual sensor 112 are all electrically connected to the controller 102, so that under the action of the controller 102, it is convenient to control whether the components electrically connected thereto are to perform opening and closing operations.

[0047] In the present invention, when it is necessary to use the drilling mechanism 1 to perform pile foundation drilling operations in the soil layer, the prepared traction equipment and the drilling mechanism 1 are first installed together (the installation principle of the spiral drilling machine) by using the hollow block 103, two mounting blocks 104, the prepared hydraulic cylinder and the prepared latch, and then the controller 102 is installed in the control room of the traction equipment, and then the controller 102 is connected to the power supply in the control room of the traction equipment, and then the controller 102 is turned on, and two verticality thresholds (the main verticality sensor 217 and the auxiliary verticality sensor 105) and the basic usage procedures are set. When everything is ready, the traction equipment console, the prepared hydraulic cylinder, the hollow block 103, the prepared latch and the two mounting blocks are used. The cooperation of the block 104 drives the drilling mechanism 1 and the correction mechanism 2 to move to the place where construction is required. Then the driver can use the controller 102 to turn on the auxiliary verticality sensor 105. Then the activated auxiliary verticality sensor 105 will detect the verticality of the drilling frame 101 and directly transmit the detected verticality data to the controller 102. After that, the controller 102 will compare the received verticality data with the verticality threshold value set in advance by the controller 102. When the verticality data received by the controller 102 is different from the verticality threshold value set in advance by the controller 102, at this time, the traction equipment console, the hollow block 103, the two mounting blocks 104, the prepared hydraulic cylinder and the prepared pins are directly used to adjust the drilling frame 1 01, when the verticality data received by the controller 102 is the same as the verticality threshold value set in advance by the controller 102, the driver can use the traction equipment console, the hollow block 103, the two mounting blocks 104, the prepared hydraulic cylinder and the prepared latch to stop adjusting the rotation of the drilling frame 101, and then use the controller 102 to turn on the main verticality sensor 217. The main verticality sensor 217 that is then started will perform a verticality detection on the lifting plate 110, and then the main verticality sensor 217 will transmit the detected verticality data to the controller 102. When the controller 102 receives the verticality data, the controller 102 will directly compare the received verticality data with the verticality threshold value set in advance by the controller 102. When the verticality data received by the controller 102 is different from the verticality threshold value set in advance by the controller 102, it means that the connection between the single-head screw rod 107 and the lifting plate 110 is not tight and there is a gap. In order not to affect the accuracy and quality of drilling and to improve the service life of the single-head screw rod 107 and the lifting plate 110, the driver can use the controller 102 to start the two first electric cylinders 204 at the same time. At this time, the two started first electric cylinders 204 will drive the second rectangular block 206 to move stably horizontally with the cooperation of the drilling frame 101, the two first rectangular blocks 201, the limit rod 205, the stabilizing frame 218, the two T-slots 202 and the two T-blocks 203.The second rectangular block 206 that moves subsequently will drive the semicircular block 213, the two connecting plates 207, the two perforated blocks 209 and the two second electric cylinders 208 to move simultaneously. Then, the two second electric cylinders 208 that move subsequently will drive the two auxiliary blocks 211, the two limit blocks 214 and the card block 212 to move simultaneously with the cooperation of the two connecting blocks 210 until the vertical data received by the controller 102 is the same as the verticality threshold value set in advance by the controller 102. When the verticality data received by the controller 102 is the same as the verticality threshold value set in advance by the controller 102, the controller 102 will simultaneously pause the two first electric cylinders 204, and then control the two second electric cylinders 208 to start simultaneously. At this time, each of the started second electric cylinders 208 will With the cooperation of the connecting block 210 connected thereto, the corresponding auxiliary block 211 is driven to move. At this time, one of the moving auxiliary blocks 211 will drive the limit block 214 and the card block 212 connected thereto to move at the same time. At the same time, the other moving auxiliary block 211 will also drive the limit block 214 connected thereto to move. When the card block 212 is docked with the card slot 215, and the two limit blocks 214 are docked with the two limit slots 216 respectively, the controller 102 is used to pause the two second electric cylinders 208. Then the driver uses the controller 102, the integrated high-precision GPS 109, the visual sensor 112, the traction device, the hollow block 103, the two mounting blocks 104, the prepared hydraulic cylinder and the prepared pin to accurately move the drill bit 114 The driver reaches the drilling position and allows the drill end surface of the drill bit 114 to contact the surface of the soil layer. Then the driver uses the controller 102 to start the second motor 111. The started second motor 111 will drive the connecting rod 113 to rotate stably with the cooperation of the lifting plate 110 after the angle is corrected. At the same time, the rotating connecting rod 113 will also drive the drill bit 114 to rotate. When the drill bit 114 starts to rotate, the driver uses the controller 102 to start the first motor 106 again. At this time, the started first motor 106 will drive the lifting plate 110 to move vertically downward with the cooperation of the drilling frame 101 and the single-head screw rod 107. At the same time, the lifting plate 110 that moves vertically downward will also drive the rotating drill bit 114 downward with the cooperation of the second motor 111 and the connecting rod 113. At the same time, when the connecting rod 113 starts to move downward, the correction mechanism 2 (except the two T-slots 202) also moves downward. When the rotating drill bit 114 starts to move downward, the soil layer is started to be drilled. When the drill bit 114 moves down to a suitable distance, the driver can use the controller 102 to control the first motor 106 and the second motor 111 to reverse. At this time, the reversed and vertically upward drill bit 114 will, with the cooperation of the pile foundation drilling and the casing 115, discharge the soil brought out from the inside of the pile foundation drilling to the surrounding of the pile foundation drilling. When the pile foundation drilling is completed, the controller 102, the integrated high-precision GPS 109, the visual sensor 112, the traction equipment, the hollow block 103, the two mounting blocks 104, the prepared hydraulic cylinder and the prepared pins are used again.The drill bit 114 is accurately moved to the next drilling position to perform the pile foundation drilling operation.

[0048] Among them, bearings are commonly used parts in reality.

[0049] Among them, the controller 102 (PLC controller), the auxiliary verticality sensor 105, the first motor 106, the integrated high-precision GPS 109, the second motor 111, the visual sensor 112, the drill bit 114, the first electric cylinder 204, the second electric cylinder 208 and the main verticality sensor 217 are all existing technologies, and their models can be selected according to actual conditions, and no excessive explanation will be given here.
