Abstract
The utility model provides a high pressure sealing drilling rod, which comprises: a drilling rod main body (1) and a sealing ring (2); a front end of a male joint of the drilling rod main body (1) is piston-shaped; an interior part of a female joint of the drilling rod main body (1) is cylinder-shaped; and the sealing ring (2) is mounted in a sealing groove on a front end of the piston-shaped male joint. The high pressure sealing drilling rod has high pressure resistance, good sealing performance and high strength and can transmit speed and torque of a drilling machine and transport high pressure water in a better way.
Description
Technical field
The utility model relates to field of mechanical technique, particularly a kind of high pressure sealing drilling rod.
Background technology
The high pressure sealing drilling rod is that coal mine gas pump drainage discharge hole bores the critical piece that cuts integration apparatus.Be mounted in the drill power head front end, connect water cutter and drill bit, be sent to drill bit to rig rotating speed and torque; Through the transfer member of water under high pressure pigtail conveying water under high pressure, present employed high pressure sealing drilling rod, poor sealing performance; Drilling rod intensity is low, does not reach to bore to cut incorporate requirement.
The utility model content
The utility model provides a kind of withstand voltage height, good seal performance, high pressure sealing drilling rod that drilling rod intensity is high.
To achieve these goals, the utility model provides following technical scheme:
The utility model embodiment provides a kind of high pressure sealing drilling rod, comprising: drilling rod main body 1 and sealing ring 2, and the male joint front end of said drilling rod main body 1 is a piston-like, piston is processed in promptly said male joint; The female joint of said drilling rod main body 1 the inside be the cylinder body shape, is processed into cylinder body inside the promptly said female joint, and said sealing ring 2 is installed in the seal groove of male joint front end of said piston-like.
Through implementing above technical scheme, have following technique effect: the withstand voltage height of high pressure sealing drilling rod that the utility model provides, good seal performance, drilling rod intensity height, can transmit rig rotating speed, torque and conveying water under high pressure better.
Description of drawings
The structural representation (the high pressure sealing drilling rod that the clamp plate type clamper is used) of first kind of high pressure sealing drilling rod that Fig. 1 provides for the utility model embodiment;
The structural representation (the high pressure sealing drilling rod that the fluid pressure type clamper is used) of second kind of high pressure sealing drilling rod that Fig. 2 provides for the utility model embodiment.
The specific embodiment
In order better to understand the technical scheme of the utility model, describe the embodiment that the utility model provides in detail below in conjunction with accompanying drawing.
The utility model embodiment provides a kind of high pressure sealing drilling rod, and is as depicted in figs. 1 and 2, comprising: drilling rod main body 1 and sealing ring 2, and the male joint front end of said drilling rod main body 1 is a piston-like, piston is processed in promptly said male joint; The female joint of said drilling rod main body 1 the inside be the cylinder body shape, is processed into cylinder body inside the promptly said female joint, and said sealing ring 2 is installed in the seal groove of male joint front end of said piston-like.When the male joint of this high pressure sealing drilling rod was connected with the female joint of another root high pressure sealing drilling rod, said sealing ring 2 played the effect of sealing, and said sealing ring 2 is sealed between piston and the cylinder body.
The withstand voltage height of high pressure sealing drilling rod that this embodiment provides, good seal performance, drilling rod intensity height can transmit rig rotating speed, torque and conveying water under high pressure better.
More than a kind of high pressure sealing drilling rod that the utility model embodiment is provided carried out detailed introduction; For one of ordinary skill in the art; Thought according to the utility model embodiment; The part that on the specific embodiment and range of application, all can change, in sum, this description should not be construed as the restriction to the utility model.
