Abstract
Gyration of hydrodrillrig rock drill and propulsion hydraulic pressure synchronizer, hydraulic rock drill slidable mounting are on propulsion - beam, and hydraulic rock drill is connected with the chain, and the chain is connected with the sprocket, and the sprocket is connected with impeing the motor, impel the motor to install on propulsion - beam, hydraulic rock drill installs the lower part bit shank, and the bit shank passes through threaded connection with the drill rod joint, hydraulic rock drill installs on upper portion gyration motor, and gyration motor drive bit shank is rotatory, impels motor and gyration motor to pass through hydraulic pressure oil pipe and links to each other with proportional control valve, turns around the diverter valve and impel the diverter valve to pass through hydraulic pressure oil pipe to link to each other with proportional control valve and unsteady flow gauging jar. The beneficial effect of the utility model: this device can be stable synchronous with rotary speed with the propulsion of hydrodrillrig, eliminate the friction effectively, the improvement of very big degree the life of bit shank.
Description
Technical field
The utility model relates to technical field of engineering machinery, is specifically the revolution of a kind of hydraulic drill rig hammer drill and advancing hydraulic pressure sychronisation.
Background technology
In the work of Modern hydraulic drill carriage, when bit shank and drilling rod in conjunction with time, advance coordinate with pivotal speed owing to manually cannot reach accurately manipulation, make connection of thread there is violent friction, the bit shank life-span reduces greatly.
Utility model content
For above-mentioned Problems existing, the utility model object is to provide the revolution of a kind of hydraulic drill rig hammer drill and advancing hydraulic pressure sychronisation.
The technical solution of the utility model is: the revolution of hydraulic drill rig hammer drill and advancing hydraulic pressure sychronisation, comprise revolution transfer valve, proportional control valve, variable-flow oil cylinder, advances transfer valve, forward beam, propulsion motor, rotary motor, hydraulic gate, chain, bit shank, sprocket wheel, drill rod joint, is characterized in that: hydraulic gate is slidably mounted on forward beam, and hydraulic gate is connected with chain, chain is connected with sprocket wheel, and sprocket wheel is connected with propulsion motor, and propulsion motor is arranged on forward beam; Hydraulic gate bottom is provided with bit shank, and bit shank and drill rod joint are threaded connection; Hydraulic gate top is provided with rotary motor, rotary motor drives bit shank to rotate, propulsion motor and rotary motor are connected with proportional control valve by hydraulic oil pipe, and revolution transfer valve and propelling transfer valve are connected with proportional control valve and variable-flow oil cylinder by hydraulic oil pipe.
The beneficial effects of the utility model: this device can be stable by synchronous with speed of gyration for the propelling of hydraulic drill rig, effectively eliminates friction, improve the application life of bit shank significantly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Now by reference to the accompanying drawings, the utility model is illustrated further.
As shown in Figure 1, hydraulic gate 8 is slidably mounted on forward beam 5, and hydraulic gate 8 is connected with chain 9, and chain 9 is connected with sprocket wheel 11, and sprocket wheel 11 is connected with propulsion motor 6, and propulsion motor 6 is arranged on forward beam 5; Hydraulic gate 8 bottom is provided with bit shank 10, and bit shank 10 and drill rod joint 12 are threaded connection; Hydraulic gate 8 top is provided with rotary motor 7, rotary motor 7 drives bit shank 10 to rotate, propulsion motor 6 and rotary motor 7 are connected with proportional control valve 2 by hydraulic oil pipe, and revolution transfer valve 1 and propelling transfer valve 4 are connected with proportional control valve 2 and variable-flow oil cylinder 3 by hydraulic oil pipe.
During work, proportional control valve 2 is opened, propulsion motor 6 is rotated forward, now switch revolution transfer valve 1 simultaneously and advance transfer valve 4, propulsion motor 6 and rotary motor 7 are connected, and due to the effect of variable-flow oil cylinder 3, hydraulic gate 8 and bit shank 10 are declined according to the rotate a circle state of a decline pitch of bit shank, severe friction and dislocation is not had with drill rod joint 12, when screw thread screws in completely, switch revolution transfer valve 1 simultaneously again and advance transfer valve 4, propulsion motor 6 and rotary motor 7 return proportional control valve 2 and control.
