Description

Technical Field

[0001] The invention relates to the technical field of drilling correction devices, in particular to a pile foundation drilling correction device and a correction method thereof. Background Art

[0002] In various construction projects, pile foundation, as an important basic structure, bears the weight of the entire building. Therefore, the construction quality of pile foundation is of vital importance. Pile foundation drilling is one of the key links.

[0003] In the existing technology, although the existing pile foundation drilling spiral drill can drill qualified pile foundation holes on the soil layer during actual use to ensure the safety and stability of the subsequent building structure, its use effect is poor. When the screw rod and the lifting plate on the spiral drill are used together for a long time, a gap may be generated between the two due to long-term contact and friction, which will lead to a loose connection between the two, thereby affecting the quality of the drilled pile foundation hole.

[0016] A correction method for a pile foundation drilling correction device includes the following steps:

[0017] S1. When it is necessary to use the drilling mechanism to perform pile foundation drilling operations in the soil layer, first use the traction equipment console, the prepared hydraulic cylinder, the hollow block, the prepared pins, and the cooperation of the two mounting blocks to drive the drilling mechanism and the correction mechanism to the place where construction is required. Subsequently, use the controller, the auxiliary verticality sensor, the verticality threshold value preset by the controller, the traction equipment console, the hollow block, the two mounting blocks, the prepared hydraulic cylinder, and the prepared pins to adjust the verticality of the drill rig.

[0018] S2. When the verticality data received by the controller is different from the verticality threshold value preset by the controller, first use the controller, the two first electric cylinders, the drill rig, the two first rectangular blocks, the limiting rod, the stabilizing frame, the two T-shaped grooves, and the two T-shaped blocks to make the second rectangular block move stably horizontally. Subsequently, use the controller, the two second electric cylinders, and the two connecting blocks to make the two auxiliary blocks, the two limiting blocks, and the clamping block move simultaneously.

[0019] S3. When the verticality data received by the controller is the same as the verticality threshold value preset by the controller, first use the controller, the two second electric cylinders, the two connecting blocks, the clamping block, the card slot, the two limiting blocks, and the two limiting grooves to make the two auxiliary blocks and the semi-circular block dock together. Subsequently, use the cooperation of the two auxiliary blocks and the semi-circular block to make the single-headed screw rod and the lifting plate connect tightly.

[0020] S4. When the verticality of the lifting plate is adjusted, first use the controller, integrated high-precision GPS, vision sensor, traction equipment, hollow block, two mounting blocks, prepared hydraulic cylinder and prepared pins to cooperate to accurately move the drill bit to the drilling position. Then use the controller, the second motor, the lifting plate after correcting the angle and the connecting rod to cooperate to drive the drill bit to rotate stably. Then use the controller, the first motor, the drill rig and the single-head screw rod to cooperate to drive the lifting plate to move vertically downward. After that, the vertically moving lifting plate will also cooperate with the second motor and the connecting rod to drive the rotating drill bit to move downward to drill the soil layer.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. By setting a correction mechanism, the present invention can make corrections when the connection between the single-head screw rod and the lifting plate is not tight, thereby ensuring the qualified quality of the drilled pile foundation holes and improving the service life of the single-head screw rod and the lifting plate. When the verticality data received by the controller is different from the verticality threshold set by the controller in advance, first use the controller, two first electric cylinders, drill rig, two first rectangular blocks, limiting rod, stabilizing frame, two T-shaped grooves and two T-shaped blocks to cooperate to enable the second rectangular block to move stably horizontally. Then use the moving second rectangular block to cooperate to enable the semi-circular block, two connecting plates, two perforated blocks and two second electric cylinders to move simultaneously. Then use the controller, two second electric cylinders and two connecting blocks to cooperate to enable the two auxiliary blocks, two limiting blocks and the clamping block to move simultaneously;

[0023] 2. When the verticality data received by the controller is the same as the verticality threshold set by the controller in advance, first use the controller to cooperate to pause the two first electric cylinders simultaneously. Then use the controller, two second electric cylinders and two connecting blocks to cooperate to enable the two auxiliary blocks to move towards each other. Then use the clamping block, clamping groove, two limiting blocks and two limiting grooves to cooperate to enable the two auxiliary blocks and the semi-circular block to be butted together. After that, use the two auxiliary blocks and the semi-circular block to cooperate to enable the connection between the single-head screw rod and the lifting plate to be tight, that is, to ensure the qualified quality of the pile foundation holes for later drilling;

[0024] 3. By setting a drilling rig mechanism, the present invention can perform pile foundation drilling operations on the soil layer. When it is necessary to use the drilling mechanism to perform pile foundation drilling operations on the soil layer, first use the traction equipment console, the prepared hydraulic cylinder, the hollow block, the prepared pins and two mounting blocks to cooperate to drive the drilling mechanism and the correction mechanism to the place where construction is required. Then use the controller, the auxiliary verticality sensor, the verticality threshold set by the controller in advance, the traction equipment console, the hollow block, two mounting blocks, the prepared hydraulic cylinder and the prepared pins to cooperate to adjust the verticality of the drill rig.

[0025] 4. When the verticality of the lifting plate of the present invention is adjusted properly, first, by using the controller, integrated high-precision GPS, vision sensor, traction device, hollow block, two mounting blocks, prepared hydraulic cylinder and prepared pins in cooperation, the drill bit can be accurately moved to the drilling position. Subsequently, by using the controller, the second motor, the lifting plate after the angle is corrected and the connecting rod in cooperation, the drill bit can be driven to rotate stably. Then, by using the controller, the first motor, the drill rig and the single-thread screw rod in cooperation, the lifting plate can be driven to move vertically downward. After that, the vertically downward moving lifting plate will also cooperate with the second motor and the connecting rod to drive the rotating drill bit to move downward, that is, the rotating and downward moving drill bit is used to perform the drilling operation on the soil layer.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Refer to Figures 1-8 As shown: A pile foundation drilling correction device includes a drilling mechanism 1, and a correction mechanism 2 is arranged on the drilling mechanism 1;

[0038] The correction mechanism 2 includes two first rectangular blocks 201, two T-shaped grooves 202 and a main verticality sensor 217. A T-shaped block 203 is slidably connected inside each T-shaped groove 202. First electric cylinders 204 are installed on the front surfaces of the two first rectangular blocks 201. A stabilizing frame 218 is installed between the front surfaces of the two first rectangular blocks 201. A second rectangular block 206 is installed between the telescopic ends of the two first electric cylinders 204. Two symmetrically arranged connecting plates 207 and perforated blocks 209 are fixed on the front surface of the second rectangular block 206. A limit rod 205 is fixed at the middle position of the rear surface of the second rectangular block 206. Second electric cylinders 208 are installed on the opposite sides of the two connecting plates 207. Connecting blocks 210 are installed at the telescopic ends of the two second electric cylinders 208. Auxiliary blocks 211 are fixed on the opposite sides of the two connecting blocks 210. A clamping block 212 is fixed on one side of one of the auxiliary blocks 211. A semi-circular block 213 is fixed at the middle position of the front surface of the second rectangular block 206. Limit blocks 214 are fixed on the sides of the two auxiliary blocks 211 close to the second rectangular block 206. A card slot 215 is opened on the side of the other auxiliary block 211 close to the clamping block 212. Two symmetrically arranged limit grooves 216 are opened on the front surface of the semi-circular block 213.

[0039] As Figures 1-3 and Figures 6-8 shown, the front surfaces of the two T-shaped blocks 203 are respectively fixed to the surfaces of the two first rectangular blocks 201. One end of the telescopic ends of the two first electric cylinders 204 movably penetrates the front surface of the inner wall of the stabilizing frame 218, and one end of the limiting rod 205 away from the connecting plate 207 movably penetrates the front surface of the stabilizing frame 218. It is convenient that, with the cooperation of the limiting rod 205, the two T-shaped grooves 202, the two T-shaped blocks 203, the two first rectangular blocks 201 and the stabilizing frame 218, the two first electric cylinders 204 can drive the second rectangular block 206 to move stably horizontally together.

[0040] As Figure 2 , Figure 4 , Figure 7 and Figure 8 shown, the fixed ends of the two second electric cylinders 208 are respectively movably sleeved inside the two perforated blocks 209. The clamping groove 215 is adapted to the clamping block 212, and the two limiting grooves 216 are respectively adapted to the two limiting blocks 214. The front surface of the semi-circular block 213 and the surface of the two auxiliary blocks 211 close to the second rectangular block 206 are on the same horizontal plane. It can improve the stability when the second electric cylinder 208 drives the connecting block 210 to move under the action of the auxiliary block 211.

[0041] As Figure 1 , Figure 3 and Figures 5-7 shown, the drilling mechanism 1 includes a drill frame 101 and a controller 102. The two T-shaped grooves 202 are symmetrically opened on the front surface of the drill frame 101. The surface of the two first rectangular blocks 201 close to the drill frame 101 is in contact with the front surface of the drill frame 101. It is convenient that, with the cooperation of the two first rectangular blocks 201, the two T-shaped grooves 202 and the two T-shaped blocks 203, the two first electric cylinders 204 can always maintain a horizontal state.

[0042] As Figure 1 , Figure 3 , Figure 5 and Figure 6 shown, a hollow block 103 is fixed to the rear surface of the drill frame 101 near the bottom position, two symmetrically arranged mounting blocks 104 are fixed to the rear surface of the drill frame 101 near the top position, an auxiliary verticality sensor 105 is installed on the surface of the drill frame 101, a first motor 106 is installed on the top of the drill frame 101, and a single-head screw rod 107 is rotatably embedded at the bottom of the inner wall of the drill frame 101. It can drive the lifting plate 110 to move with the cooperation of the first motor 106, the single-head screw rod 107 and the drill frame 101.

[0043] As Figure 1 , Figure 3 , Figure 5 andFigure 6 As shown, the top end of the single-headed screw rod 107 movably penetrates through the top of the inner wall of the drill rig 101. The top end of the single-headed screw rod 107 is installed with the output end of the first motor 106. A T-shaped platform 108 is fixed at the top of the drill rig 101, and an integrated high-precision GPS 109 is installed on the top of the T-shaped platform 108. A lifting plate 110 is slidably connected inside the drill rig 101. The main verticality sensor 217 is installed on the front surface of the lifting plate 110, which facilitates driving the main verticality sensor 217 to move under the action of the lifting plate 110.

[0044] As Figure 1 , Figure 3 , Figure 5 , Figure 6 and Figure 8 As shown, the bottom end of the single-headed screw rod 107 threadedly penetrates through the top of the lifting plate 110. The front surface of the drill rig 101 is in contact with the surface of the lifting plate 110. A second motor 111 is installed on the top of the lifting plate 110. The integrated high-precision GPS 109 is directly above the second motor 111. The output end of the second motor 111 is installed with a connecting rod 113, which can drive the drill bit 114 to rotate under the cooperation of the connecting rod 113, the lifting plate 110 and the second motor 111.

[0045] As Figures 1-8 shown, the bottom of the second rectangular block 206, the bottom of the semi-circular block 213 and the bottoms of the two auxiliary blocks 211 are all in contact with the upper side of the connecting rod 113. The top end of the connecting rod 113 is rotatably connected inside the through hole of the lifting plate 110 through a bearing. A drill bit 114 is installed at the bottom of the connecting rod 113. A sleeve 115 is fixed at a position near the top of the front surface of the drill rig 101. A vision sensor 112 is installed inside the surface groove of the sleeve 115, which facilitates accurately moving the drill bit 114 to the drilling position under the cooperation of the controller 102, the integrated high-precision GPS 109, the vision sensor 112, the traction device, the hollow block 103, the two mounting blocks 104, the preparation hydraulic cylinder and the prepared pins.

[0046] As Figures 1-3 and Figures 5-8 shown, the drill bit 114 is movably sleeved inside the sleeve 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. The auxiliary verticality sensor 105, the first motor 106, the integrated high-precision GPS 109, the second motor 111 and the vision sensor 112 are all electrically connected to the controller 102, which facilitates controlling whether the components electrically connected thereto are opened or closed under the action of the controller 102.

[0047] In the present invention, when it is necessary to use the drilling mechanism 1 to perform pile foundation drilling operation on the soil layer, first, the prepared traction equipment and the drilling mechanism 1 are installed together by using the hollow block 103, two mounting blocks 104, the prepared hydraulic cylinder and the prepared pins (the installation principle of the auger). Subsequently, the controller 102 is installed in the control room of the traction equipment. Then, the controller 102 is connected to the power supply in the control room of the traction equipment. After that, 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 program are set. When everything is ready, the drilling mechanism 1 and the correction mechanism 2 are driven to the construction site by using the traction equipment console, the prepared hydraulic cylinder, the hollow block 103, the prepared pins and the two mounting blocks 104. Subsequently, the driver can turn on the auxiliary verticality sensor 105 by using the controller 102. Then, the started auxiliary verticality sensor 105 will detect the verticality of the drill rig 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 previously set by the controller 102. When the received verticality data by the controller 102 is different from the verticality threshold previously set by the controller 102, at this time, the verticality of the drill rig 101 is adjusted directly by using the traction equipment console, the hollow block 103, the two mounting blocks 104, the prepared hydraulic cylinder and the prepared pins. When the received verticality data by the controller 102 is the same as the verticality threshold previously set by the controller 102, at this time, the driver can use the traction equipment console, the hollow block 103, the two mounting blocks 104, the prepared hydraulic cylinder and the prepared pins to stop adjusting the rotation of the drill rig 101. Then, the main verticality sensor 217 is turned on by using the controller 102. Then, the started main verticality sensor 217 will detect the verticality of the lifting plate 110. After that, the main verticality sensor 217 will transmit the detected verticality data to the controller 102. When the controller 102 receives the verticality data, at this time, the controller 102 will directly compare the received verticality data with the verticality threshold previously set by the controller 102. When the received verticality data by the controller 102 is different from the verticality threshold previously set by the controller 102, it indicates that the connection between the single-headed screw rod 107 and the lifting plate 110 is no longer tight and there is a gap. At this time, in order not to affect the drilling accuracy and quality and improve the service life of the single-headed screw rod 107 and the lifting plate 110, the driver can use the controller 102 to start the two first electric cylinders 204 simultaneously. Then, the started two first electric cylinders 204 will drive the second rectangular block 206 to move stably horizontally together under the cooperation of the drill rig 101, two first rectangular blocks 201, the limiting rod 205, the stabilizing frame 218, two T-shaped grooves 202 and two T-shaped blocks 203.Subsequently, the moving second rectangular block 206 will drive the semi-circular block 213, two connecting plates 207, two perforated blocks 209 and two second electric cylinders 208 to move simultaneously. Then, the two moving second electric cylinders 208 will, with the cooperation of two connecting blocks 210, drive two auxiliary blocks 211, two limiting blocks 214 and the clamping block 212 to move simultaneously until the vertical data received by the controller 102 is the same as the verticality threshold preset by the controller 102. When the verticality data received by the controller 102 is the same as the verticality threshold preset by the controller 102, at this time, the controller 102 will pause the two first electric cylinders 204 simultaneously, and then control the two second electric cylinders 208 to start simultaneously. At this time, each started second electric cylinder 208 will, with the cooperation of the connecting block 210 connected thereto, drive the corresponding auxiliary block 211 to move. At this time, one of the moving auxiliary blocks 211 will drive the limiting block 214 and the clamping block 212 connected thereto to move simultaneously, and the other moving auxiliary block 211 will also drive the limiting block 214 connected thereto to move. When the clamping block 212 is docked with the card slot 215 and the two limiting blocks 214 are respectively docked with the two limiting slots 216, at this time, use the controller 102 to pause the two second electric cylinders 208. Subsequently, the driver uses the controller 102, the integrated high-precision GPS 109, the vision sensor 112, the traction device, the hollow block 103, two mounting blocks 104, the prepared hydraulic cylinder and the prepared pins to cooperate to accurately move the drill bit 114 to the drilling position and make the drill bit end surface of the drill bit 114 contact the soil surface. Then, the driver uses the controller 102 to start the second motor 111. After that, the started second motor 111 will, with the cooperation of the lifting plate 110 after the angle is corrected, drive the connecting rod 113 to rotate stably. 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, at this time, the driver uses the controller 102 to start the first motor 106. At this time, the started first motor 106 will, with the cooperation of the drill rig 101 and the single-headed screw rod 107, drive the lifting plate 110 to move vertically downward. At the same time, the vertically downward moving lifting plate 110 will, with the cooperation of the second motor 111 and the connecting rod 113, drive the rotating drill bit 114 to move downward. At the same time, when the connecting rod 113 starts to move downward, the correction mechanism 2 (except for the two T-shaped grooves 202) also moves downward. When the rotating drill bit 114 starts to move downward, that is, the drilling operation on the soil layer starts. When the drill bit 114 moves downward to an appropriate distance, at this time, the driver can use the controller 102 to control the first motor 106 and the second motor 111 to reverse. At this time, the reversely rotating and vertically upward moving 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 periphery of the pile foundation drilling. When the pile foundation drilling is completed, at this time, use the controller 102, the integrated high-precision GPS 109, the vision sensor 112, the traction device, the hollow block 103, two mounting blocks 104, the prepared hydraulic cylinder and the prepared pins to cooperate again,Accurately move the drill bit 114 to the next drilling position for pile foundation drilling operation.

[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 vision sensor 112, the drill bit 114, the first electric cylinder 204, the second electric cylinder 208, and the main verticality sensor 217 are all prior arts, and their models can be selected according to actual situations and will not be elaborated here.
