Abstract
The utility model relates to a power head and walk interlocking device of a rotary drilling rig, which comprises a pilot oil pump, a pilot oil line channel, a two-position four-way electromagnetic reversing valve, a pressure oil channel of a walk pilot valve, a pressure oil channel of a power head pilot valve, the power head pilot valve and the walk pilot valve and is characterized in that the two-position four-way electromagnetic reversing valve is connected between the walk pilot valve and the power head pilot valve and controls the pressure oil channels of the walk pilot valve and the power head pilot valve so as to lead the walk pilot valve and the power head pilot valve to be interlocked to prevent from acting simultaneously. In the device, the electromagnetic reversing valve is used to switch pilot valve pressure oil of the power head and the walk, so as to interlock the actions of the walk and the pressure head, thereby effectively reducing the problems that a drill rod and a pile hole are misplaced when the power head is in a work state, and a drill wedging rod, the drill rod and the pile hole are difficult to be aligned and the like, effectively preventing faults and improving the safety of the drilling rig; and the power head and walk interlocking device is easy to control, is practical and can be widely applied to various rotary drilling rigs.
Description
Technical field
The utility model relates to the rotary drilling rig that uses in a kind of engineering construction, particularly a kind of rotary digging drill power head and walking interlock.
Background technique
Rotary drilling rig is the efficient pore-forming equipment of heavy caliber that uses in a kind of foundation construction, and the drilling rod that its utilization remains Vertical direction directly rotates, excavates ground, thereby forms the stake hole of the required diameter and the degree of depth fast on ground.This rotary drilling rig since power big, power is strong, easy to use, pore-forming is quick, so in the foundation construction process of the engineering of being widely used in, building.Existing rotary drilling rig medium power head work and running motor work are separate, two final controlling element concurrently-actings, unit head belongs to the operation final controlling element, walking belongs to the adjustment final controlling element, the working state of action simultaneously not between two actions, if but the walking misoperation will cause drilling rod and the dislocation of stake hole under unit head piling working state, cause problems such as other drilling rod, drilling rod and stake hole difficulty align, if proper functioning when influencing unit head boring is the generation that the people also causes the accident easily for misoperation.
The model utility content
The utility model is to provide a kind of device by the guide oil of rotary digging drill power head and walking is carried out interlocking, and the shortcoming in asking with solution above-mentioned background skill is with not enough.
The technical problem that the utility model solved realizes by the following technical solutions:
A kind of rotary digging drill power head and walking interlock, comprise guide's oil pump, guide oil paths, two four-way electromagnetic reversing valves, walking pilot valve pressure oil passage, unit head pilot valve pressure oil passage, unit head pilot valve, walking pilot valve, it is characterized in that, be connected with two four-way electromagnetic reversing valves between walking pilot valve and the unit head pilot valve, two four-way electromagnetic reversing valves make walk pilot valve and unit head pilot valve carry out interlocking by control walking and pressure head pilot valve pressure oil passage and can not move simultaneously.
Beneficial effect: the utility model is by the pilot valve pressure oil between solenoid directional control valve switching unit head and the walking, interlocking is carried out in two actions, effectively reduced the drilling rod and problems such as a stake hole dislocation, other drilling rod, drilling rod and a hole difficulty align of unit head under in working order, effectively prevented simultaneously the generation of accident, improved the Security of rig, its application cylinder list, practicality can be widely used on the various rotary drilling rigs.
Description of drawings
Fig. 1 is a structure principle chart of the present utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete accompanying drawing, further set forth the utility model:
See Fig. 1, a kind of rotary digging drill power head and walking interlock, comprise guide's oil pump 1, guide oil paths 2, two four-way electromagnetic reversing valves 3, walking pilot valve pressure oil passage 4, unit head pilot valve pressure oil passage 5, unit head pilot valve 6, walking pilot valve 7, be connected with 3, two four-way electromagnetic reversing valves 3 of two four-way electromagnetic reversing valves between walking pilot valve 7 and the unit head pilot valve 6 by controlling two pilot valve pressure oil passages and make walking pilot valve 7 and unit head pilot valve 6 carry out interlocking and can not moving simultaneously.
In the process of work, guide's oil pump 1 provides pressure oil, through guide oil paths 2, two four-way electromagnetic reversing valves 3 must not the electricity situation under, guide oil flows to walking pilot valve 7 through walking pilot valve pressure oil passage 4, the action of walking pilot valve, corresponding running motor action, finish the moving of rig, adjust the position of boring; When the boring operating mode is prepared in adjustment intact back in position, provide pressure oil by guide's oil pump 1, through 2 to two four-way electromagnetic reversing valves 3 of guide oil paths, two four-way electromagnetic reversing valves 3 get at this moment, guide oil flows to unit head pilot valve 6 through unit head pilot valve pressure oil passage 5, the action of unit head pilot valve, corresponding unit head action, pilot valve 7 inner fluids of walking simultaneously are back to fuel tank.With regard to the pilot valve of walking at last action is arranged like this and corresponding running motor does not have action yet, avoided the variety of issue that when boring, causes because of the walking misoperation.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
