Abstract
The utility model provides a power drill capable of bearing a hanging load, which belongs to the technical field of oil drilling. The power drill structurally comprises a lower universal joint connector and a main transmission shaft, a spline sleeve is arranged between the upper end of the main transmission shaft and the lower universal joint connector and is sleeved on the upper end of the main transmission shaft through a spline, the outer wall of the spline sleeve is in threaded connection with the lower universal joint connector through rectangular threads, the upper end of the main transmission shaft is provided with a hanging load clamp, and the lower end of the main transmission shaft is provided with a male buckle connector or a female buckle connector. Due to the spline sleeve arranged at the connection part of a universal joint and the main shaft, torque can be simultaneously transmitted at the internal connection part and the external connection part of the spline sleeve. With the hanging load clamp and a thrust block, the load hanging capacity of the power drill can be improved, and the safety can be greatly guaranteed. Since the lower end of the main shaft is provided with a male buckle, no adapter is needed, and the main shaft can be directly connected with other downhole tools on the power drill, the length of the power drill below the single bend can be minimized, and the power drill can be applied in straight-screw power drills and power drills with small single bends.
Description
Technical field
The utility model relates to the oil drilling technology field, specifically a kind of suspending weight carrying power drilling tool.
Background technology
General, the current driving force drilling tool has developed into the indispensable downhole tool in oil drilling field, in the construction of exceptional well type, irreplaceable effect is arranged, but because power drilling tool is at the underground work inclement condition, all easily rupturing in main shaft and universal joint place, motor and universal joint place, shortens the application life of power drilling tool.The power drilling tool lower end can only connect drill bit and the lighter downhole tool of weight, and can not connect other greater weight downhole tools, and available dynamic drill spindle structure can not be carried the greater weight downhole tool.
Available dynamic drilling tool motor is with universal joint, universal joint and all use rectangular thread to connect being connected of main shaft place, it is little, stressed concentrated to put forth effort area, can not bear big outstanding carrying and moment of torsion, the main shaft lower end is designed for box, connect other drilling tools as need, also need be equipped with two male joints, increase the curved length of power drilling tool list again, strengthen the load of power drilling tool.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of suspending weight carrying power drilling tool is provided.
The technical solution of the utility model realizes in the following manner, this suspending weight carrying power drilling tool, its structure comprises universal joint lower contact and transmission main shaft, be provided with spline housing between transmission main shaft upper end and the universal joint lower contact, spline housing is connected on the transmission main shaft upper end by spline housing, the spline housing outer wall is threaded with the universal joint lower contact by rectangular thread, and the transmission main shaft upper end is provided with the suspending weight clip, and the transmission main shaft lower end is set to male joint or box joint.
The spline housing lower limb is provided with thrust block.
Be provided with sealing ring between spline housing lower inner wall and the transmission main shaft.
The beneficial effect that the utility model is compared with prior art produced is:
This suspending weight carrying power drilling tool is to develop the power drilling tool that can carry big suspending weight according to the deficiency of existing power drilling tool, its main feature is motor and universal joint junction, main shaft is used a kind of novel keyway instead with the universal joint junction and is connected simultaneously with rectangular thread, spline housing is installed in junction at universal joint and main shaft, the main shaft upper end interconnects with the splined shaft inner sleeve, the spline housing outside has rectangular thread and universal joint to be connected and fixed, thereby make all while transfer torques of the inside and outside junction of spline housing, in the main shaft upper end suspending weight clip is set, there is thrust block the spline housing lower end, both increased the suspending weight ability of power drilling tool, increased safety guarantee again, the pin thread design is adopted in the main shaft lower end, do not need crossover sub, can directly connect other downhole tools that carried, shorten the curved following length of power drilling tool list to greatest extent, can be widely used in the oil drilling technology field.
This suspending weight carrying power drilling tool is reasonable in design, simple in structure, safe and reliable, easy to use, be easy to safeguard, helps improving devices work efficient and application life.
