The Development Of A Automatic Cutting Machine For Mine Dual Anchor Cables

With the continuous development of coal technology, underground supporting technology has been continuously improved, bolt and anchor cable has become the main mode of mine roadway support, different roadway and working face often require different length of anchor cable, and anchor cable is a package when they were carried out of factory, so cutting anchor cable need according to the actual demand of cable size, cutting anchor cable with ground expansion after feeding,bending fixed transport to the underground and then expand the installation, in the process of cutting anchor cable, the traction and cutting links of anchor cable are realization of artificial, low degree of automation, and high risk, there is no controlled facilities in the cable show put process, runaway phenomenon have the occurrence, the whole bundle cable easy loose, lead cable cutting length are not allowed, and often produce cable out to hurt people or cutting blade collapse of wounding incident.In this paper, aiming at the above problems, we have design a automatic cutting machine for mine dual anchor cables, mainly including Actinobacillus wheel, traction system, cutting system, discharging system and discharge line wheel brake for supporting the installation of discharge line wheel, the mine dual anchor cable automatic cutting machine adopts hydraulic transmission, pneumatic transmission and electric control system combined, the putting on the line, pressing and discharging of anchor cable adopt pneumatic transmission, quick and reliable in operation, using PLC as the core control system, realizes the machine, electricity, liquid, gas integration control. According to the designed control program, control system control the movement of hydraulic cylinder, the cylinder and the reversing valve, completed the required a variety of actions of actionmycetes, traction, cutting and unloading the anchor cables, and the feeding machine has the explosion-proof function.Mechanical design of this paper has completed the design calculation of Actinobacillus wheel, traction system, cutting system, discharging system and discharge line wheel brake for supporting the installation of discharge line wheel, Put the wire disc through screw adjustment, can realize the change of working diameter, under the wire disc installing four universal wheels, it intend to move the wire disc easily, designing cable locking device on the chassis of wire disc, to reduce the anchor projectile wounding incident; traction system adopts chain transmission device, a traction part by roller compacting to transport the anchor cable, the distance of two rollers is adjustable, it can transport different diameter anchor; cutting system adopt the abrasive cutting wheel, the whole structure is designed to be mobile, so that it can be fully the use of grinding wheel piece, also can reduce the error generated during the cutting; discharge the system is removable, by controlling the control system can realize the unilateral and bilateral unloading; this paper uses the ANSYS software for the roll wheel in the traction system, casters and spindle in condition of static analysis, the results show that, the traction system components stability and strength meet the requirements, but also on the traction system box was optimized; the main drive part load traction system kinematics simulation was carried out by using ADAMS software, get the movement rule between the pressing wheel and anchor.The design of the automatic cutting machine for mine dual anchor cables in this paper not only realize objective of the rapid, efficient in cutting anchor cable, it can greatly reduce the inputs in human and material, eliminating the risk factors, the safety factor is high, the original more collaboration, easy to produce with mistakes, and to tension, easy to play hurt, implementation full automatic homework now, greatly improve the safety coefficient.
