Novel drilling method vertical shaft boring machine

Abstract

The invention provides a novel drilling method vertical shaft boring machine. The novel drilling method vertical shaft boring machine comprises a derrick and a hydraulic pump station; a lifting mechanism is arranged on the upper part of the derrick; the lifting mechanism is connected with a sliding frame; the sliding frame is arranged on the derrick in a sliding mode; the sliding frame is sequentially connected with a tightening mechanism and a propelling mechanism through a drill rod; the tightening mechanism is connected with the propelling mechanism; the propelling mechanism is connected with a stabilizer and a cutter head; the stabilizer is matched with the cutter head; and the hydraulic pump station is connected with the lifting mechanism, the propelling mechanism and the stabilizer respectively. The construction concept of a tunnel boring machine is introduced into vertical shaft construction, power submerged driving is adopted, no balance weight exists underground, the drill roddoes not need to transmit torque and only bears the gravity load, ultra-deep drilling construction is achieved, a driving system, a supporting shoe propelling system, the stabilizer and other structures are all placed underground, the cutter head is directly driven to break rock, the supporting shoe provides supporting force, a propelling oil cylinder provides propelling force, the rock breakingcapacity and efficiency of the cutter head are improved, and efficient and accurate drilling construction is achieved.

Description

technical field [0001] The invention relates to the technical field of drilling and boring machines, in particular to a novel shaft boring machine for well drilling. Background technique [0002] The traditional shaft drilling rig adopts top drive, drill pipe transmission, gas lift reverse circulation slag removal, and decompression drilling construction. The top drive adopts full hydraulic drive to drive the drill pipe, the stabilizer stabilizes the drill pipe, drives the bottom cutterhead for excavation, and the spherical tooth hob for rock breaking. Using low-penetration and high-speed drilling method, the rock mass is broken into small pieces of slag, and the mud water circulation is generated by the gas lift method, and the slag is carried to the ground by the high-speed circulating mud water, and then passed through the sedimentation tank, separation station, etc. , separate the rock slag from the mud water, and the mud water enters the recirculation to complete the r...

AI Technical Summary

Problems solved by technology

However, the equipment still has the following problems, which seriously restrict the popularization and application of the equipment, mainly including: 1. The drill pipe is too long and flexible, which limits the improvement of the torque of the cutterhead; 2. The cutterhead has no stabilizing device and is prone to deflection , causing damage to the cutter head, cutter, drill pipe, etc.; 3. Using gravity guidance, drilling is prone to problems such as deflection and reaming; 4. Problems such as collapsed holes, buried drills, and falling objects during drilling are difficult 5. The construction efficiency in hard rock formation is low; 6. The verticality of the sinking well wall is not suitable to be controlled, and the filling quality of the wall thickness is not easy to control.

[0003] At present, the patent application number is "CN201410106744.1" and the patent name is "New Drilling Method Shaft Drilling Rig", which discloses a drilling method shaft drilling rig that improves drilling efficiency. In the process, the drill pipe is still used to transmit the torque, the transmission torque is small, and the construction energy consumption is large
