Problems solved by technology

Because the overall weight of the skeleton seal ring is heavy when installed, and the skeleton seal ring is closely matched with the hollow shaft, the inner ring of the skeleton seal ring is relatively smaller than the outer diameter of the hollow shaft, which makes installation difficult. It cannot be guaranteed, and it is easy to damage the inner sealing ring, resulting in the failure of the sealing effect

Abstract

The invention belongs to the technical field of maintenance and assembly of a rotary drill rig, in particular to an installation guide device of a skeleton sealing ring of a hollow shaft of a rotary drill rig and a use method. The installation guide device of the skeleton sealing ring of the hollow shaft of the rotary drill rig is composed of a cone shaft and a force applying wrench which is plugged with the cone shaft. The middle part of the large-diameter end surface of the cone shaft is provided with an outer-cone threaded post, and the surrounding of an excircle is provided with a thin-wall plug bush. The outer-cone threaded post is in threaded connection with a cone threaded hole arranged on the end surface of the hollow shaft, and the inner surface of the thin-wall plug bush is connected with the outer surface of the hollow shaft in a mode of clearance fit. The small-diameter end of the cone shaft is provided with a through hole plugged with the force applying wrench. The force applying wrench is a cylindrical pin shaft. According to the installation guide device, the problems that the original skeleton sealing ring is difficultly installed, or the precision is poor and the like. The installation guide device is easily operated and is conveniently controlled, adjusted and centered, and the installation precision is ensured. The installation strength is effectively reduced, the manpower resource is saved, and the installation efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of maintenance and assembly of roller cone drilling rigs, and in particular relates to a guide device for installing and using a hollow shaft skeleton sealing ring of a roller cone drilling rig and a method for using it. Background technique [0002] The rotary pressurizing mechanism of the roller drilling rig is mainly composed of a rotary gearbox and a hollow shaft. The hollow shaft runs through the middle of the rotary gearbox. The hollow shaft is an important part for conveying high-pressure air and water. A Two skeleton sealing rings are used to seal the bearings on the hollow shaft to prevent the hollow shaft from entering the reduction box when it is rotating. The installation quality of the skeleton sealing rings directly affects the sealing effect. The drilling rig shuts down. Because the overall weight of the skeleton seal ring is heavy when installed, and the skeleton seal ring is closely matched...
