Intelligent self-driven rotary drilling rig device

Abstract

The invention provides an intelligent self-driven rotary drilling rig device. The intelligent self-driven rotary drilling rig device comprises a tool bit (1), an inner cutterhead (2), an outer cutterhead (3), a drilling bucket (4), a power chamber (5), a supporting shoe (6), a transmission shaft (7), a telescopic rod (8), a linkage shaft (9) and a gyroscope (10). The cutterhead is arranged at the lowermost end, and the drilling bucket is connected to the cutterhead; the power chamber is connected right above the drilling bucket through the transmission shaft, and the linkage shaft is mounted on the upper part of the power chamber; the cutterhead is composed of the inner cutterhead and the outer cutterhead, the central axis of the inner cutterhead coincides with the central axis of the outer cutterhead, and the outer cutterhead and the inner cutterhead are concentric circular cutterheads; the rotating directions of the two cutterheads are opposite; and torque self-balance is achieved by adjusting and outputting the output power of the inner cutterhead and the outer cutterhead. By adopting the inner cutterhead structure and the outer cutterhead structure with different rotating directions, the torque on the linkage shaft is zero by correspondingly adjusting the output power of the inner cutterhead and outer cutterhead, so that the purpose of self-balancing the torque is achieved, and the energy consumption is reduced.

Description

technical field [0001] The invention relates to an intelligent self-driving rotary drilling rig device, which belongs to the technical field of construction machinery. Background technique [0002] With the rapid development of civil engineering in our country, rotary drilling rigs have been developing in the direction of large-scale and gigantic. Due to its fast construction speed, low environmental pollution, high degree of automation, flexible and convenient operation, high safety performance, and strong applicability, rotary drilling rigs are widely used in hole-forming operations in basic engineering, especially in high-rise buildings, railways and Construction work on the bridge. [0003] Rotary drilling rig is a construction machine suitable for hole-forming operations in building foundation engineering. It is mainly suitable for construction in soil layers such as sandy soil, cohesive soil, and silty soil. been widely used in. Usually, the power head device of the...

Problems solved by technology

However, the power devices of traditional rotary drilling rigs are all located in the upper locomotive, which makes the rotating shaft of the rotary drilling rig bear a large torque with the increase of the excavation depth, and the traditional rotary drilling rig has a longer force arm. Larger torque, resulting in higher energy consumption

[0004] In addition, traditional rotary drilling rigs cannot distinguish the degree of softness and hardness of the rock formation and cannot automatically adjust the rotation speed of the rotary drilling rig according to the soft and hard conditions. This makes the sudden change in the stiffness of the soil when the soft rock enters the hard rock formation during the drilling process. certain damage
