Abstract

Variable-diameter pile digging equipment comprises four wheels, four first stepper motors, four wheel frames, four first servo motors, four first electric cylinders, four trusses, a support plate, a first gear, a second servo motor, an optical axis, a second stepper motor, a soil containing box and a drill bit assembly. The variable-diameter pile digging equipment has the following advantages thata unique truss structure is adopted and can stretch out and draw back in the left, right, front and rear directions so as to adapt to piles with different diameters, and the adaptability of the variable-diameter pile digging equipment is improved; the unique drill bit assembly is adopted, the diameters of drill bits and drill holes are variable, pile holes with different diameters can be dug, thus the pile digging cost is saved, the efficiency and quality of pile digging are greatly improved, and the labor intensity of workers is relieved; and the unique soil containing box is adopted, loosened soil is collected while drilling is conducted, and thus the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of construction machinery and equipment, in particular to pile digging equipment with variable diameter. Background technique [0002] With the rapid development of the economy, China's real estate industry has risen rapidly and maintained this hot state for a long time. High-rise buildings are spread all over the cities. Before building a building, it is necessary to dig pile holes and build pile foundations. The traditional way of digging piles is manually digging piles. It often takes several days or even ten days for workers to dig a pile. The labor intensity is high and the efficiency is low, and the quality is difficult to guarantee. Therefore, pile diggers are often used instead of labor at the construction site, but The mechanical equipment on the market is bulky, complex in structure, and high in cost of use. For example, a drilling bucket type pile digging device with application number 20161063989...
