Description
Technical field
The utility model relates to a kind of automatically pressure limiting protection system of engineering machinery, and specifically a kind of horizontal directional drilling machine automatically pressure limiting protection system, belongs to directional drilling machine technical field.
Background technology
At present, horizontal directional drilling machine is left, the setting of right rotation maximum pressure is to realize by the overflow valve in hydraulic system, once directional drilling machine is left, after the pressure setting of right rotation overflow valve, a left side for this system, right rotation pressure just cannot be changed, directional drilling machine is left, during right rotation work, when engineering less, user often selects compared with jig drill bar by reducer union, during rig work, left, right rotation pressure cannot reach overflow valve and set maximum pressure, when drilling rod or when return expanding head and running into the larger obstruction of the resistances such as ratchel or drift sand, usually drilling rod is twisted distortion or drilling rod and the damage of drilling rod junction screw thread, easily cause construction accident, the personnel that cause injure.
Summary of the invention
The problem existing for above-mentioned prior art, the utility model provides a kind of horizontal directional drilling machine automatically pressure limiting protection system, avoids the damage of unit head, drilling rod and system, guarantees the construction safety of directional drilling machine and staff's personal safety.
For achieving the above object, a kind of horizontal directional drilling machine automatically pressure limiting of the utility model protection system, this protection system comprises battery main switch, battery, fuse, key switch, rotational pressure sensor, controller, left-handed electromagnetic valve and dextrorotation electromagnetic valve; The negative pole of battery is by battery main switch ground connection, and the positive pole of battery is connected to key switch B by fuse and holds, and key switch ACC end connects controller 101 ends, controller 102 end ground connection; Rotational pressure sensor 1,2 ends are connected respectively to controller 269,137 ends; Controller 104 and 116 ends connect respectively the left and right electromagnetic valve positive terminal that revolves, the left and right electromagnetic valve negative pole end that revolves of controller 277 terminations.
Compared with prior art; the utility model to horizontal directional drilling machine pressure limiting protect; avoided drilling rod when running into the larger obstruction of the resistances such as ratchel or drift sand; being twisted distortion or drilling rod and drilling rod junction screw thread damages; thereby protect safely and effectively unit head, drilling rod and pipeline; guaranteed the construction safety of directional drilling machine, increased work efficiency.
Accompanying drawing explanation
Fig. 1 is the utility model electrical block diagram.
In figure, 1, battery main switch; 2, battery; 3, fuse; 4, key switch; 5, rotational pressure sensor; 6, controller; 7, left-handed electromagnetic valve; 8, dextrorotation electromagnetic valve.
The specific embodiment
The utility model is comprised of battery main switch 1, battery 2, fuse 3, key switch 4, rotational pressure sensor 5, controller 6, left-handed electromagnetic valve 7, dextrorotation electromagnetic valve 8; The negative pole of battery 2 is by battery main switch 1 ground connection, and the B that positive pole is connected to key switch 4 by fuse 3 holds, and the ACC end of key switch 4 connects 101 ends of controller 6,102 end ground connection of controller 6; 1,2 ends of pressure sensor 5 are connected respectively to 269,137 ends of controller 6; 104 and 116 ends of controller 6 connect respectively left and right electromagnetic valve 7,8 positive terminals that revolve, left and right electromagnetic valve 7,8 negative pole ends that revolve of 277 terminations of controller 6.
Described controller 6 is TTC60 controller, and shell is sturdy and durable, and applicable to severe working environment, reliability is high.
When this device is constructed, the pressure of the left and right rotary system of rotational pressure sensor 5 Real-Time Monitoring, when the pressure of system does not surpass setting pressure, 104,116 ends of controller 6 have signal output, left-handed electromagnetic valve 7 or dextrorotation electromagnetic valve 8 obtain electric, and Directional Drilling function is normally carried out left-handed, dextrorotation work; When if the pressure of system surpasses setting pressure, 104,116 end no signals outputs of controller 6, left-handed electromagnetic valve 7 or dextrorotation electromagnetic valve 8 dead electricity, the left-handed or dextrorotation attonity of directional drilling machine; Some less engineerings, user can set the now pressure of rotary system according to the left and right rotation torque of selected drilling rod, when drilling rod or when return expanding head and running into the larger obstruction of the resistances such as ratchel or drift sand, the pressure rise of system, when the rotational pressure sensor 5 on left and right rotary system monitors system pressure and surpasses now setting pressure, 104,116 end no signal outputs of controller 6, left-handed electromagnetic valve 7 or dextrorotation electromagnetic valve 8 dead electricity, directional drilling machine is without left-handed or dextrorotation action.Thereby the rotary system to directional drilling machine is protected, while having avoided doing compared with unskilled labourer's journey, the damage of unit head, drilling rod and pipeline etc., guarantees the construction safety of directional drilling machine and staff's personal safety, increases work efficiency, and reduces production costs.
