Description

Technical Field

[0001] The utility model relates to the technical field of engineering machinery and equipment, in particular to a rotary drilling and pile forming device. Background Art

[0002] A rotary drilling rig is a pile-making machine used for drilling holes in building foundation projects. It has the advantages of fast construction speed, good hole quality, low environmental pollution, flexible and convenient operation, high safety performance and strong applicability. It has become the main hole-forming equipment for bored pile construction and is widely used in municipal construction, highway bridges, high-rise buildings and other infrastructure projects. As demand continues to increase, people have also put forward higher requirements for the working performance of rotary drilling rigs. A rotary drilling rig is also called an auger drill. When using an auger drill bit for construction, each time the soil drilled adheres to the drill bit, it is pulled out of the hole and rotated in the opposite direction at high speed to throw the soil off.

[0003] At present, a Chinese patent announcement with announcement number CN211874390U discloses a subway construction rotary drilling rig bored pile hole forming device, which relates to the technical field of railway construction equipment. The utility model includes a base, a vertical device plate is fixedly installed on the top of the base, a movable box is slidably installed on the device plate in the vertical direction, a lifting assembly for driving the movable box to slide up and down is arranged on the device plate, a drill rod for drilling holes is rotatably installed on the bottom of the movable box, an auger is opened around the outside of the drill rod, the auger is used to transport soil out of the hole, and a first motor for driving the drill rod to rotate is fixedly installed on the movable box. By starting the second motor, the second motor drives the mounting plate to move up and down through the conveyor belt, and starting the first motor, the first motor drives the drill rod to rotate through the transmission assembly. As the drill rod descends, the drill rod can drill holes on the ground, and the auger transports the soil out of the ground, so that the drilling can be completed.

[0004] In actual use, it is found that when the existing equipment is drilling holes in the ground, the soil brought out by the auger is often piled around the pile hole, which makes it inconvenient to clean the soil and easily causes blockage of the pile hole after the drilling is completed. There is a problem that the soil cannot be piled up in a centralized manner, which is not convenient for collecting the soil and easily causes blockage of the pile hole. Therefore, we propose a rotary drilling pile forming device to solve the above problems. Utility Model Content
