Rotating wire sling sealing device and manufacturing method of sealing sleeve thereof

Abstract

The invention particularly discloses a rotating wire sling sealing device, which comprises a steel wire rope. The device is characterized by also comprising an outer shell, an outer shell end cover, a first sealing ring, a first tensioning cover, an inner shell, an inner shell end cover, a second tensioning cover, a rotating shaft sleeve and a sealing sleeve, wherein the first sealing ring is arranged in an open hole of the outer shell end cover; a through hole is formed in the center of the first tensioning cover; the open hole of the outer shell end cover is covered by the first tensioning cover; the first tensioning cover is in threaded connection with the outer shell end cover; a hole is formed in the center of the inner shell end cover; an opening in the top of the inner shell is covered by the inner shell end cover; a through hole is formed in the center of the second tensioning cover; the opening of the inner shell end cover is covered by the second tensioning cover; an axial through hole is formed in the center of the rotating shaft sleeve; the rotating shaft sleeve is arranged in the inner shell in a sleeved manner and is connected with the inner shell in a rotating way; an annular oil storage groove is formed in the outer wall of the rotating shaft sleeve; an inner hole of the sealing sleeve has a reciprocal screw structure adapted to the steel wire rope, and is arranged in the through hole of the rotating shaft sleeve in a sleeved manner; the outer shell is arranged on the inner shell in a sleeved manner; a slurry buffering chamber is formed between the inner and outer shells. Due to the adoption of the design, the problem that slurry is scattered and injected in all directions, and loses excessively fast due to leakage in a pressed state is solved.

Description

technical field [0001] The invention relates to the field of underground construction equipment, in particular to a rotary steel wire suspension rope sealing device. Background technique [0002] The steel wire rope used in the underground construction drilling rig does not have a sealing device. When the steel wire rope is used in equipment that requires mud circulation, there will be a problem of mud ejecting from the connection between the steel wire rope and the equipment. Contents of the invention [0003] The object of the present invention is to provide a rotary steel wire rope sealing device, the purpose of which is to provide a relatively sealed space at the joint between the equipment and the steel wire rope to slow down or even prevent the loss of mud from the joint between the steel wire rope and the equipment. [0004] In order to achieve the above object, the present invention is achieved in that: [0005] A rotary type steel wire rope sealing device; it...
