Abstract
A multifunctional protection device for the power head of a rotary drilling rig belongs to protection devices for rotary drilling rigs. The protection device comprises a steel ring and a pressure plate; the steel ring is welded around the pressure plate so as to form a circular platform-shaped baffle plate; the pressure plate is arranged at the upper end of the circular platform; the lower end of the circular platform is open; eight connection holes are formed on the pressure plate; and the device is connected with a driving sleeve as a whole through bolts. Since the protection device is connected with the driving sleeve as a whole, when the rotary drilling rig is operated, slurry is thrown off from the power head component under the action of centrifugal force generated by the rotation of the driving sleeve; therefore, the phenomenon that slurry enters a dynamic box along the joint face of the driving sleeve is eliminated, and the failure rate of the power head is reduced. The multifunctional protection device has advantages of simple structure, good reliability and multifunction, can be mounted and dismounted conveniently, has the multifunctional protection effect of resisting sludge and water and throwing soil, can stop slurry from entering the dynamic box as well as throw soil, and is applicable to power head structures of all types of rotary drilling rigs.
Description
Technical field
The utility model relates to a kind of multifunctional protection device that digs brill that revolves, particularly a kind of rotary digging drill power head multifunctional protection device.
Background technology
Power head part is as very crucial equipment in the rotary drilling rig, and its performance quality will directly influence the service behaviour of whole rig.Main effect is to drive drilling rod, drill bit revolution, and can provide boring required plus-pressure, lifting force, and rotary drilling rig gets rid of soil at a high speed and low speed creeps into two kinds of operating mode construction requirements to satisfy, thereby by each rotary drilling rig production firm extensive use.
But in practical work process, unit head often is in the environment that mud sheds works, because the rotation of unit head actuating sleeve, mud is easy to enter in the casing of unit head, causes the premature failure of meshing gear, thereby reduces the application life of unit head.Owing to the sealing performance that also can further damage unit head casing lower end that enters of mud, cause the consequence of the serious leakage of oil of unit head.
The utility model content
The purpose of this utility model is to provide a kind of: rotary digging drill power head multifunctional protection device, in order to solve the application life of reducing unit head in the casing that mud enters into unit head, damage the sealing performance of unit head casing lower end, cause the problem of the serious leakage of oil of unit head.
The purpose of this utility model is achieved in that this protector comprises steel ring and pressing plate, at pressing plate border welding steel ring, constitutes round table-like baffle plate, pressing plate is positioned at the upper end of round platform, the lower ending opening of round platform has eight connecting holes on pressing plate, connect as one by bolt and actuating sleeve.
Beneficial effect, owing to adopted such scheme, this protector connects as one with actuating sleeve, utilize between the rotary drilling rig operational period, the centrifugal action that the actuating sleeve rotation produces throws away power head part with mud, eradicated mud and entered headstock inside, reduced the fault rate of unit head along the mating face of actuating sleeve.Solve mud and entered into the application life of reducing unit head in the casing of unit head, damaged the sealing performance of unit head casing lower end, caused the problem of the serious leakage of oil of unit head, reached the purpose of this utility model.
Advantage: simple in structure, good reliability is installed and convenient disassembly, the multifunctional protection effect that has anti-mud, waterproof and get rid of soil can prevent that mud from entering power box inside, can get rid of soil again, one-object-many-purposes is applicable to the power head structure of various types of rotary drilling rigs.
Description of drawings
Fig. 1 is a structure chart of the present utility model.
Fig. 2 is a mud prevention device installation drawing of the present utility model.
Among the figure, 1, pressing plate; 2, steel ring; 3, bolt; 4, actuating sleeve.
The specific embodiment
Embodiment 1: this protector comprises steel ring 2 and pressing plate 1, at pressing plate 1 border welding steel ring 2, constitutes round table-like baffle plate, and pressing plate 1 is positioned at the upper end of round platform, and the lower ending opening of round platform has eight connecting holes on pressing plate, connect as one by bolt 3 and actuating sleeve 4.
During installation, on the actuating sleeve upper surface, evenly smear fluid sealant earlier, again the pressing plate of this protected apron is put down gently on the actuating sleeve, pressing plate is fixed on the actuating sleeve by the former connecting bolt of actuating sleeve.
During work, this protector rotates with the rotation of actuating sleeve, and protector is round table-like structure, in rotating process, utilize the centrifugal force produced will trickle down mud around unit head and foreign matter get rid of to around, thereby avoided mud to enter in the headstock.
