Integrated Drilling Rig for Bolt-while-Driving Drilling

Abstract

The invention discloses a boom-type roadheader mounted tunneling anchor-along drilling integrated drilling machine which mainly consists of a steel plate structural piece and a hydraulic system, wherein the steel plate structural piece of the drilling machine comprises a main withdrawing and release arm, a drilling machine rack, a vertical rotary mechanism and a horizontal rotary mechanism; the hydraulic transmission system of the drilling machine comprises a drilling hole hydraulic motor, a drilling machine horizontal rotary hydraulic motor, a drilling machine vertical rotary hydraulic motor, a telescopic leg hydraulic cylinder, a drilling machine thrust hydraulic cylinder, a hydraulic control element and a hydraulic auxiliary element. The drilling machine is characterized in that the drilling machine and a tunneling machine are integrally combined and are distributed on two sides of a tunneling machine cantilever, and the walking of the drilling machine is achieved through a walking mechanism of the tunneling machine. Holes can be drilled in an all-direction and multifunction manner in a tunneled roadway, both anchor bolt support and top plate lithology detection can be achieved, and drilling of shotholes, drilling of gas sucking and discharge holes, geologic drilling and the like can be achieved, and facilities and methods are provided for safe, rapid and efficient roadway tunneling.

Description

technical field [0001] The invention relates to a drilling rig used in underground roadway excavation for surrounding rock support and geological drilling, in particular to a cantilever-type roadheader airborne integrated drilling rig for anchor-while-drilling. Background technique [0002] Bolt support has the advantages of low cost, fast roadway formation, small auxiliary transportation volume, low labor intensity, and high utilization rate of roadway sections. The development direction of protection technology. With the rapid development of bolting technology, bolting rigs have also been developed rapidly, but it is still one of the main reasons restricting the rapid promotion of coal roadway bolting technology in our country. [0003] The rock bolt rigs mainly include single-type rock bolt rigs and platform-type rock bolt rigs. The advantages of single-type rock bolt rigs: simple structure, easy processing and manufacturing, low price, and low technical requirements for...

AI Technical Summary

Problems solved by technology

Disadvantages of single-type rock bolter: the drilling diameter is small, the hole depth is small, and manual handling is required

Disadvantages of platform rock bolter: expensive, not suitable for small section roadways

The disadvantages of the above two geological drilling rigs compared with bolting rigs are: the equipment is heavy and bulky, and it is very difficult to transport, move, fix, install and dismantle underground. When the geological conditions of the working face change rapidly, the drilling rig needs to be frequently transported and fixed. , installation and dismantling, so the workload is heavy, the labor intensity is high, and the roadway excavation speed is slow, which seriously restricts the improvement of excavation efficiency, and the small section roadway cannot even be used

However, bolter drilling rigs and geological drilling rigs cannot effectively cooperate with roadheaders. The efficiency is low, the labor intensity of workers is high, the speed of tunneling is slow, and the operating rate of roadheaders is only about 40%. Research and development of cantilever roadheader airborne anchor-while-drilling integrated drilling rig to achieve safe, efficient and rapid excavation

[0007] At present, the permanent support of domestic coal mine excavation roadway is designed based on experience, and the lithology and rock structure of the roadway roof cannot be detected in time, so that the design of permanent support cannot be changed in time according to the roof situation, and sometimes roof accidents are caused due to insufficient support strength. Sometimes excessive support strength causes waste, reducing the speed and benefit of tunneling
