[0016] In order to make the purpose, technical scheme and advantage of the utility model more clear and obvious, below combining with specific embodiment and referring to drawings, the utility model is further detailedly explained.Should understand, these descriptions are only exemplary, and not to limit the scope of the utility model.Moreover, in following explanation, the description of known structure and technology is omitted, to avoid unnecessary confusion of the concept of the utility model.

[0017] As Figure 1 As shown in a kind of roller drill jack oil cylinder overhaul oil pipe device, including reducing oil pipe joint 1, large diameter oil pipe joint 2, oil pipe fastening nut 3, oil pipe nut knurl 4, small end cap 5, large end cap 6, rubber tube 7, the thread of reducing oil pipe joint 1 small head is screwed into roller drill jack oil cylinder oil return hole, the thread of large diameter oil pipe joint 2 is screwed into jack oil cylinder oil inlet hole, oil pipe nut knurl 4 and rubber tube 7 are connected by oil pipe fastening nut 3 and are fixed, rubber tube 7 both ends are equipped with oil pipe nut knurl 4, the thread connection of rubber tube 7 reducing oil pipe joint 1 big head, the other end is connected with the thread of large diameter oil pipe joint 2.

[0018] The utility model discloses a jack is removed from the jack shell, and the jack supporting disc is grounded but has no supporting force, and at this time, the upper cavity oil of jack is more, and the lower cavity oil is less. After removing the oil pipe, the small plug 5 is screwed into the thread of the oil return hole 9, and the big plug 6 is screwed into the thread of the oil inlet hole 8. At this time, the upper and lower cavities are isolated by the piston, and the upper and lower cavities cannot be connected. The jack is taken out from the shell and is placed in the maintenance support vertically. The small plug 5 is removed, the small head of the reducing oil pipe joint 1 is screwed into the oil return hole 9, the oil pipe nut bamboo joint 4 is passed through the oil pipe fastening nut 3 and is inserted into the rubber pipe 7 with a diameter of 16mm. The iron wire is tied firmly. If conditions are available, the rubber pipe 7 and the oil pipe fastening nut 3 can be pressed and formed by the pipe pressing machine. The big head of the reducing oil pipe joint 1 is screwed into the oil pipe fastening nut 3. The thread of the large diameter oil pipe joint 2 is screwed into the thread of the oil inlet hole 8 of the jack oil cylinder, and the thread of the large diameter oil pipe joint 2 is connected with the rubber pipe 7 and the oil pipe fastening nut 3. At this time, the upper and lower cavities of the oil cylinder are connected through the rubber pipe, the oil cylinder piston rod is slowly pulled up to the upper limit position, and the upper cavity oil enters the lower cavity through the oil return piston rod body hole-oil return hole-maintenance oil pipe device-oil inlet hole-piston rod body hole. At this time, the upper cavity has no oil, and the lower cavity has the most oil. The jack oil cylinder bolt is removed, the gland is opened, the piston rod is pulled out, the seal is maintained and replaced, and the reverse process of the removal is carried out. The bolt is tightened, the gland is pressed, and at this time, the upper cavity has no oil, and the lower cavity has the most oil. As the piston rod slowly enters, the lower cavity oil enters the upper cavity through the oil inlet piston rod body hole-oil inlet hole-oil pipe maintenance device-oil return piston rod body hole, the upper cavity oil gradually increases, the lower cavity oil gradually decreases, and when the lower limit position is reached, the lower cavity has no oil, and the upper cavity has the most oil. The added maintenance oil pipe is removed, the big plug 6 and the small plug 5 are replaced, and then the jack is placed in the jack shell (the added oil pipe cannot enter the jack shell, so this step is needed). The big plug 6 and the small plug 5 are removed, the oil pipe is connected to the drilling rig itself, the supporting disc pin shaft is inserted, and the maintenance task is completed.

[0019] It should be understood that the above specific embodiments of the utility model are only used for example or explanation of the principle of the utility model, and do not constitute the limitation of the utility model. Therefore, any modification, equivalent replacement, improvement, etc. made without deviating from the spirit and scope of the utility model shall be included in the protection scope of the utility model. In addition, the appended claims of the utility model are intended to cover all changes and modifications falling within the scope and boundary of the appended claims or the equivalent forms of such scope and boundary.
