Each hydraulic jack on drill boom and forward beam, it is achieved moving up and down and rotary movement of rock drill.It is provided with on rock drill
Drill steel and bore bit, after rock drill is adjusted to operating position, rock drill drives drill steel and bore bit to carry out rock drilling bore operation.Now
Driving drill carriage, after when driving drill carriage, at a driving, stroke completes, propelling stroke completes, and when now, hydraulic gate is also entering
Row impact, and hydraulic gate is not pushed ahead, and arises that " sky is beaten " phenomenon." sky is beaten " phenomenon easily causes hydraulic gate
Damage, affect the service life of rock drill.
It is therefore desirable to a kind of device of design, after making propelling stroke complete, hydraulic gate is automatically stopped impact, it is to avoid when
Propelling stroke completes and " sky is beaten " phenomenon occurs.
Summary of the invention
In order to solve the problems referred to above, the purpose of this utility model is to provide a kind of after propelling stroke completes, and can make chisel
Rock machine is automatically stopped the most whole aperture apparatus of impact.
In order to realize above-mentioned purpose, this utility model have employed following technical scheme: a kind of driving drill carriage is automatically eventually
Aperture apparatus, including hydraulic gate, hydraulic gate is arranged on forward beam by slide block, and propelling cylinder controls slide block along advancing
Beam slides, and forward beam is provided with collision block and stroke valve, after propelling stroke completes, clashes between collision block and stroke valve, OK
Journey valve is connected with hydraulic system, and described hydraulic system includes impact/propelling hydraulic control pilot valve and impact/propelling pilot operated valve device, described
Impact/advance the oil-out of pilot operated valve device to connect propelling cylinder and hydraulic gate, impact/advance hydraulic control pilot valve and punching respectively
Hitting/advance and be provided with pilot operated directional control valve between pilot operated valve device, the signal hydraulic fluid port of pilot operated directional control valve is connected with stroke valve.
Above-mentioned driving drill carriage whole aperture apparatus automatically, collision block and stroke valve are arranged on hydraulic gate propelling stroke on forward beam
Terminal.When being in propelling stroke, stroke valve separates with collision block, and pilot operated directional control valve is opened, impact/advance hydraulic control pilot valve
Unimpeded to the oil circuit of impact/propelling pilot operated valve device, the propelling of propelling cylinder and the impact of hydraulic gate are carried out simultaneously；When advancing row
After journey completes, stroke valve clashes into collision block, and hydraulic oil makes hydraulicdirectional control valve complete commutation through stroke valve, cuts off by impact/PF
Control pilot valve, to the oil circuit control of impact/propelling pilot operated valve device, impacts/advances pilot operated valve device and reset, cut off entrance propelling cylinder and control
The working connection of hydraulic gate processed impact, makes propelling cylinder stop advancing, and hydraulic gate stops impact.
Above-mentioned driving drill carriage aperture apparatus at end, makes the propelling of propelling cylinder and the percussion action of hydraulic gate carry out simultaneously,
Avoid, when propelling stroke completes rock drill, " sky is beaten " phenomenon occurs.
