Description

Technical Field

[0002] Bored cast-in-place piles refer to cast-in-place piles that are bored with a drilling machine at the pile location. There are many types of drilling machines, including spiral drills, submersible drills, impact drills, etc. Bored cast-in-place piles are widely used in engineering as a form of foundation bearing capacity due to their noise-free, vibration-free nature, low environmental impact, and high bearing capacity. With the construction of various water conservancy buildings, they are widely used in engineering as a form of foundation bearing capacity.

[0003] When using the existing water conservancy construction injection hole expansion device, the hole is usually expanded using an expansion plate.

When the active bevel gear 881 rotates, it drives the rotating shaft to rotate through the driven bevel gear 882. When the rotating shaft rotates, it drives the rotating cone The bevel gear 883 rotates, and when the rotating bevel gear 883 rotates, the outer tube 6 is driven to rotate through the transmission bevel gear 884, and the drill bit 5 is also driven to rotate at this time. When the movable plate 81 moves downward, it also drives the square tube 88 to rotate when it moves on the outside of the square rod 87. When the drill bit 5 rotates and moves downward, drilling is performed. When it reaches a certain position, the hydraulic cylinder A73 can be operated, thereby driving the reaming plates 71 on both sides to move in the opposite direction. After moving to a suitable position, the hydraulic cylinder A73 can be operated. At this time, the reaming plate 71 rotates with the outer tube 6. After the reaming is completed, the hydraulic cylinder A73 is operated in the reverse direction to drive the reaming plate 71 to move in the reverse direction to recover. When the reaming plate 71 moves, it drives the movable gear 75 to move on the fixed rack plate 74. When the cam 77 is rotated, the movable gear 75 is driven to rotate, and the cam 77 is driven to rotate through the driven gear 76. When the cam 77 rotates to contact the adjacent push plate 78, it pushes it to move toward the inner wall of the inner cavity of the expansion plate 71 and squeezes the adjacent return spring 782. At the same time, it also drives the knocking ball 79 to knock the inner wall of the inner cavity of the expansion plate 71 through the knocking spring 791. The dirt and other impurities can be shaken off by the vibration. When the cam 77 rotates away from the push plate 78, the push plate 78 will be restored under the action of the rebound force of the return spring 782. Since the cam 77 is constantly rotating, it will drive the knocking ball 79 to knock the inner wall of the inner cavity of the expansion plate 71 back and forth, which is beneficial to the recovery of the expansion plate 71.When the threaded sleeve 82 moves downward, it will drive the moving rack plate 92 to move downward through the U-shaped rod A91. When the moving rack plate 92 moves downward, it will drive the rotating gear 93 to rotate. When the rotating gear 93 rotates, it will drive the ratchet plate A931 to rotate through the movable shaft A. When the ratchet plate A931 rotates, it will fit the ratchet plate B932 to rotate and continuously squeeze the telescopic spring 934. When the hole expansion is completed, the servo motor A86 can drive the transmission rod to rotate in the opposite direction. At this time, the threaded sleeve 82 can be driven to move upward to recover. When the threaded sleeve 82 moves upward, it will also drive the hole expansion plate 71 and the drill bit 5 to move upward to recover, and the moving rack plate 92 will move upward, thereby driving the rotating gear 93 to rotate in the opposite direction. When the rotating gear 93 rotates in the opposite direction, it will drive the ratchet plate B932 to rotate through the ratchet plate A931. When the ratchet plate B932 rotates, it will The telescopic spring 934 drives the disc 933 to rotate. When the disc 933 rotates, it drives the movable bevel gear 94 to rotate through the movable shaft B. When the movable bevel gear 94 rotates, it drives the reciprocating screw 96 to rotate through the rotating bevel gear 95. When the reciprocating screw 96 rotates, it drives the screw nut 97 to move back and forth left and right. When the screw nut 97 moves left and right, it drives the piston to move back and forth left and right in the piston cylinder 99 through the special-shaped connecting rod 98, so that the clean water in the inner cavity of the water tank 991 can be continuously sucked, and the outer tube 6 moving upward is sprayed and flushed through the annular spray pipe 992. With the movement of the outer tube 6, the expansion plate 71 and the outer side of the drill bit 5 are also flushed. If the expansion plate 71 is difficult to retract, it can be recovered after flushing to a certain extent. The operation is convenient. When it is restored, the reciprocating screw 96 will stop rotating.
