Abstract
The utility model discloses a hydraulic pressure rock drilling machine dust arrester fan governor belongs to engineering machine tool technical field, this regulator including the oil feed unit that is linked together with hydraulic motor one end and with the unit that produces oil that the hydraulic motor other end is linked together, the oil feed unit including with the check valve parallel connection after the first overflow valve that is linked together with first hydraulic fluid port of magenetic exchange valve and second hydraulic fluid port respectively again, produce oil the unit including with the second overflow valve that magenetic exchange valve third hydraulic fluid port links to each other, magenetic exchange valve's control end and controller electricity are connected. The utility model discloses can solve and have great pressure difference between hydraulic pressure rock drilling machine dust arrester hydraulic motor's the both ends hydraulic fluid port, produce hydraulic motor's inertia, make the problem that the fan can not in time stop.
Description
Technical field
The utility model relates to technical field of engineering machinery, especially a kind of adjuster for hydraulic rock drilling machine dust arrester fan.
Background technology
Hydraulic rock drilling machine be a kind of with hydraulic oil as powered piston impact hammer drill and with the rock drilling machinery of independent slew gear. It can produce a large amount of dust in quarrying process, in order to reduce this class dust to atmosphere pollution and the harm to human health, is conventionally provided with dust arrester in hydraulic gate. A kind of dust arrester that drives fan rotation dust adsorption by hydraulic motor, exist in the time that hydraulic rock drilling machine quits work, between the two ends hydraulic fluid port of hydraulic motor, there is larger pressure difference value, produce the inertia of hydraulic motor, fan can not be stopped in time, extend the time cycle that the blowback of dust arrester filter core is rinsed, reduced the problem of hydraulic rock drilling machine operating efficiency.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of hydraulic rock drilling machine dust arrester fan control, this adjuster can solve between the two ends hydraulic fluid port of hydraulic rock drilling machine dust arrester hydraulic motor and have larger pressure difference value, produces the problem that the inertia of hydraulic motor can not stop fan in time.
In order to address the above problem, the technical scheme that the utility model adopts is: this hydraulic rock drilling machine dust arrester fan control includes the oil-feed unit being connected with hydraulic motor one end and the fuel-displaced unit being connected with the described hydraulic motor other end, and described oil-feed unit includes the first overflow valve being connected with solenoid directional control valve the first hydraulic fluid port and the second hydraulic fluid port respectively with check valve Lian Houzai; Described fuel-displaced unit includes the second overflow valve being connected with described solenoid directional control valve the 3rd hydraulic fluid port; The control end of described solenoid directional control valve is electrically connected with controller.
In technique scheme, technical scheme can also be more specifically: the oil-in of described the first overflow valve, the oil-out of described check valve and described solenoid directional control valve the first hydraulic fluid port are connected with the first hydraulic fluid port of described hydraulic motor, and the oil-in of described the second overflow valve and described solenoid directional control valve the 3rd hydraulic fluid port are connected with the second hydraulic fluid port of described hydraulic motor; The oil-out of the oil-out of described the first overflow valve, the oil-in of described check valve, described the second overflow valve and described solenoid directional control valve the second hydraulic fluid port are connected with fuel tank.
Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect:
Because the two ends hydraulic fluid port of hydraulic motor is communicated with respectively the first overflow valve and the second overflow valve that are connected with solenoid directional control valve; In the time that boring finishes, can be by setting up the force value of the first overflow valve and the force value of the second overflow valve, the pressure difference value of hydraulic motor two ends hydraulic fluid port is close, thereby shorten the braking time of hydraulic motor, the time cycle that the blowback of dust arrester filter core is rinsed is shortened, improved the operating efficiency of hydraulic rock drilling machine.
Brief description of the drawings
Fig. 1 is the hydraulic schematic diagram of the utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail:
Hydraulic rock drilling machine dust arrester fan control shown in Fig. 1, include oil-feed unit and fuel-displaced unit, oil-feed unit includes the first overflow valve 2 and check valve 7 in parallel, the oil-in 2a of the first overflow valve, the oil-out 7b of check valve 7 and solenoid directional control valve 3 first hydraulic fluid port 3a are connected with the first hydraulic fluid port 5a of hydraulic motor 5, fuel-displaced unit includes the second overflow valve 4, the oil-in 4a of the second overflow valve 4 and solenoid directional control valve 3 the 3rd hydraulic fluid port 3c are connected with the second hydraulic fluid port 5b of hydraulic motor 5, the oil-out 2b of the first overflow valve 2, the oil-in 7a of check valve 7, the oil-out 4b of the second overflow valve 4 and solenoid directional control valve 3 second hydraulic fluid port 3b are connected with fuel tank, hydraulic motor 5 is connected with pump 1 with the first hydraulic fluid port 5a, the control end 3A of solenoid directional control valve 3 is electrically connected with controller 6.
When work, the force value of setting up the first overflow valve 2 is operating pressure value 18MPa, and the force value of setting up the second overflow valve 4 is 6MPa; Connect the power supply of controller 6, controller 6 control pump 1 active rigs start boring, control solenoid directional control valve 3 with Time Controller 6 and be operated in left position, pump 1 pressure oil out drives hydraulic motor 5 work to drive fan rotation, dust arrester starts dust suction, and the oil return of hydraulic motor 5 is through the directly oil return case of left position of solenoid directional control valve 3; In the time that boring finishes, controller 6 is controlled solenoid directional control valve 3 and is operated in right position, hydraulic motor oil return is got back to fuel tank through the second overflow valve 4, because the pressure difference value between the first hydraulic fluid port 5a and the second hydraulic fluid port 5b of hydraulic motor is 12MPa, be less than the pressure difference value 18MPa between former hydraulic motor 5 first hydraulic fluid port 5a and the second hydraulic fluid port 5b; The described braking time that shortens hydraulic motor 5, shortens the time cycle that the blowback of dust arrester filter core is rinsed, and has improved the operating efficiency of hydraulic rock drilling machine.
