Problems solved by technology

[0003] Due to the large volume and weight of existing rotary drilling rigs, it is usually only possible to dig holes in areas with relatively flat terrain. For hilly terrain with uneven terrain, it is difficult for rotary drilling rigs to walk to the construction site However, it is also difficult for rotary drilling rigs to dig holes stably at the construction site, and there are great potential safety hazards. Therefore, in the drilling construction of mountains and hills, manual digging is usually used, which has low efficiency, high strength, and certain construction risks.

Abstract

The invention discloses a depth feeding device for a hole digging machine, which comprises a support frame, a mounting frame and a lifting mechanism. The lifting mechanism is connected, the middle part of the installation frame is connected with a first installation ring, the middle part of the support frame is connected with a second installation ring, a casing is passed through the first installation ring and the second installation ring, and the bottom of the casing is used to connect the rotary digging device. The device is convenient for transportation in uneven terrain such as mountains and hills, and can stably assist the rotary digging mechanism to perform hole digging operations at the construction site.

Description

technical field [0001] The invention relates to the field of hole digging machines, in particular to a depth feeding device for a hole digging machine. Background technique [0002] Rotary drilling rig is a construction machine suitable for hole-forming operations in building foundation engineering. It is mainly suitable for the construction of sandy soil, cohesive soil, silty soil and other soil layers. It is widely used in various foundation constructions such as cast-in-place piles, diaphragm walls, and foundation reinforcement. The rated power of rotary drilling rigs is generally 125-450kW. The output torque is 120-400kN m, the maximum hole diameter can reach 1.5-4m, and the maximum hole depth is 60-90m, which can meet the requirements of various large-scale foundation construction. [0003] Due to the large size and weight of existing rotary drilling rigs, it is usually only possible to dig holes in areas with relatively flat terrain. For hilly terrain with uneven terr...
