Description

Technical Field

[0001] This invention belongs to the technical field of drilling rigs, and specifically relates to a long spiral drilling and grouting pile device. Background Technology

[0002] The most commonly used equipment for pile foundation construction is the auger pile driver, due to its advantages of simple operation, ease of use, and high drilling efficiency. However, due to factors such as the torque of the power head, vibration resistance, impact resistance, and pile frame height, its construction range is narrow, and it cannot be used for drilling in rock strata. Currently, buildings are constantly expanding in height and facing various geological challenges. Among these challenges, the construction of CFG pile composite foundations is particularly difficult under high groundwater levels and extremely thick gravel geology.

[0003] Chinese patent CN105804650B (application number CN201610195169.6) discloses a long spiral drilling rig with a simple structure, robust and reliable construction, attractive appearance, and flexible operation. It is convenient to use, maintain, and repair, and has high relocation efficiency, significantly reducing labor intensity, improving production efficiency, and saving production costs. Disassembly and assembly are simple and convenient; the main unit can be mounted on a flatbed truck using its own chassis system, greatly shortening the machine's relocation time and reducing the workload. Simultaneously, it can remove adhering materials from the drill bit and drill rod in real time, improving work quality and speed.

[0004] The harsh environment, complex terrain, and abundant pebbles present challenges to CFG pile composite foundations, including slow construction speed, high mechanical damage rate, and difficult drilling. Traditional long auger drilling rigs cannot detect cracks or other easy drilling locations in the pebbles, resulting in a significant waste of construction equipment and time. Furthermore, the drill bits and drill rods of traditional long auger drilling rigs are prone to damage, making it difficult to improve construction efficiency. Summary of the Invention

[0016] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting cutting teeth, the frequency of drill gate damage is reduced; by setting the drill pipe and drill gate to a tongue and groove shape, sewage and sand are prevented from entering the drill pipe through the drill gate during drilling; by setting the length of the drill gate to about 0.5m, the possibility of the drill gate falling off is reduced; by setting two protective irons on the casing, the possibility of the casing wall tearing due to insufficient strength during drilling is reduced; by setting the distance between the spiral blades to 0.3m and the thickness to 0.2m, and the diameter of the drill pipe to 0.6m and the thickness to 0.2m, the damage to the drill pipe is reduced.

[0017] The traveling device includes a slewing mechanism, a crossbeam, and a traveling trolley. The slewing mechanism includes a slewing motor, a slewing bearing, and a turntable. The machine body and the turntable are connected via the slewing bearing, and the machine body and the turntable rotate relative to each other under the drive of the slewing motor. The crossbeam includes an insertion hole, a ball head, and a pin. The upper part of the crossbeam has an insertion hole, and the lower part has a ball head.

[0019] The rotating mechanism includes a rotary motor and a rotating gimbal. The rotating gimbal is fixedly connected to the drill rod, and the output shaft of the rotary motor is connected to the rotating gimbal to drive the power head to rotate.

[0020] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting a rotary motor, the rotation of the power head can be controlled; by setting a rotary gimbal, the power head can be fixed.

[0021] The top of the machine body is equipped with a winch, which is connected to the rotating mechanism by a steel cable; a pulley block is also provided between the winch and the rotating mechanism, and the steel cable is wound around the pulley block.

[0022] The beneficial effects of adopting the above-mentioned improvement scheme are: by setting up a winch and pulley system, the lifting and lowering of the power head can be controlled.

This system avoids damage caused by violent collisions between the drill bit and pebbles. A walking mechanism allows for horizontal movement and rotation of the entire system. A crack detection device enables the detection of cracks in pebbles, making drilling into whole pebbles easier and solving the problem of traditional long auger drilling rigs failing to detect cracks and other easily accessible drilling locations in pebbles, resulting in significant waste of equipment and time. Cutting teeth reduce the frequency of drill gate damage. A tongue-and-groove design between the drill rod and drill gate prevents sewage and sand from entering the drill rod during drilling. A drill gate length of approximately 0.5m reduces the possibility of it detaching. Two protective iron rings on the casing reduce the possibility of the casing wall tearing due to insufficient strength during drilling. A 0.3m distance between the auger blades and a 0.2m thickness, along with a 0.6m diameter and 0.2m thickness drill rod, reduces drill rod damage, addressing the problem of easily damaged drill bits and drill rods in traditional long auger drilling rigs, which hinders construction efficiency.
