Foldable all-around drilling mechanism

Abstract

The invention relates to a foldable all-around drilling mechanism which comprises a base plate, a turning oil cylinder, a turning frame, a slewing bearing, a guide rail and a power head, wherein the folding of the turning frame is controlled through the telescopic effect of a piston rod of the turning oil cylinder; one end of the slewing bearing is fixedly arranged on the turning frame; the otherend of the slewing bearing is connected with the guide rail; and the power head is arranged at the side, opposite to the side connected with the slewing bearing, of the guide rail. The foldable all-around drilling mechanism has the advantages that the structure is reasonable; the foldable all-around drilling mechanism has two states including a transportation state and a work state; the transportation requirements of a coal mine underground narrow roadway can be met; the machine dismounting transportation is avoided; the equipment fault probability caused by the assembly by unprofessional minepersonnel is effectively reduced; the installation and the use are convenient; convenience, high speed and reliability are realized; the construction range is effectively expanded, so that the efficiency is improved; the use effect is good; the stress effect of the power head is better; the abrasion generated by swinging is avoided; and the integral service life of the drilling mechanism is effectively prolonged. Compared with the prior art, the foldable all-around drilling mechanism has good market prospects and development space.

Description

technical field [0001] The invention relates to the technical field of underground drilling rods in coal mines, in particular to a foldable omnidirectional drilling mechanism. Background technique [0002] Coal is the main body of primary energy in my country and plays a pivotal role in the entire energy structure. As the coal mines in our country deepen at a rate of 10-30m every year, gas disasters, especially coal and gas outburst disasters, are becoming more and more serious. Gas control is an important part of safe coal mining. In order to improve the effect of gas extraction, drilling rigs are often used to construct gas drainage holes. However, the underground tunnels of coal mines are generally narrow, and as the power of drilling rigs increases, correspondingly, the volume of drilling rigs also increases. When the height of the drilling rig exceeds the roadway conditions, it needs to be dismantled and transported, and it is very inconvenient to transport and use un...

Problems solved by technology

[0004] In order to solve the problem that the underground roadways of traditional coal mines are generally narrow, as the power of the drilling rig increases, the volume of the drilling rig becomes larger and larger accordingly. For technical problems such as very inconvenient transportation and use, the present invention provides a foldable omni-directional drilling mechanism to achieve reasonable structure, ingenious design, and two states of transportation and working, which can meet the transportation requirements of narrow roadways in coal mines and avoid Disassembly and transportation effectively reduces the probability of equipment failure caused by non-professional mine personnel assembly. It is easy to install and use, convenient and reliable, and effectively increases the scope of construction, thereby improving efficiency, good use effect, and better force on the power head. , to avoid the wear caused by the swing, and effectively improve the overall life of the drilling mechanism
