Background technique
Large-scale mine drilling machine is common in the mineral products such as large outdoors colliery, iron ore area, is that a kind of generate on mining area surface layer is bored
Into blast hole/exploration hole special equipment is obtained, the depth of typically hole reaches tens of rice to thousands of rice.Feeding in such equipment
System is core component therein, and which determine the maximum loads of drilling machine and effective power to weight ratio (output work for the size of propulsive force
The ratio between rate and system weight).
It is mainly based upon the feeding system of double-acting type oil cylinder push for the feed system of large type drill both at home and abroad at present
System.The system is made of components such as balladeur train assembly, feed cylinder, rotary gear box and wirerope.Balladeur train assembly is by upper and lower two
Pulley blocks are constituted, and are connected respectively with the upper/lower terminal of feed cylinder cylinder.Feed cylinder is double-acting type, the work at cylinder tube both ends
Stopper rod is connected with a public piston, which is typically for up to 10m or more.It is total that the both ends of feed cylinder piston rod are fixed on boring tower
At top and bottom near.When hydraulic oil rushes at any side of piston, cylinder tube and upper and lower pulley blocks along boring tower above and below
It is mobile, so that system generates downward or upward propulsive force.It is total by boring tower that high-intensitive wirerope passes through upper and lower two pulley blocks
It is connected at the adjustable anchor point of immediate vicinity with swiveling head.When balladeur train is moved up and down along boring tower, swiveling head also can be towards phase
Same direction is mobile, but speed is twice of balladeur train.Since double-acting type long stroke oil cylinder is utilized, cause the system cost high
It is expensive, structure is complicated.Simultaneously as the oil cylinder both ends are separately fixed at the bottom and top of boring tower assembly, lead to oil cylinder and boring tower
The two leads to the problem of strut stability under the action of oil cylinder propulsive force, so that the maximum output for limiting feed system promotes
Power.In addition, cause the piston rod of oil cylinder to be easy to hit with generations such as external rubbles since the working environment in mine is severe, into
And sealing is led to problems such as to be destroyed and generate hydraulic system fault.
