Description
Technical field
The utility model relates to a kind of drilling rod elevator, relates to a kind of anti-sludge-type rotary drilling rig that is widely used in the rotary drilling rig industry specifically and uses the drilling rod elevator.
Background technology
Rotary drilling rig is one of widely used equipment in rotary drilling rig field with the drilling rod elevator, belongs to the particular component that has in the rotary drilling rig use than the high safety reliability requirement.Wire rope when not receiving loaded-up condition thigh and strand between tighten; When master winch has just begun to promote drilling rod; Wire rope begins stressed tension; Wire rope can produce one revolving force under the load of axis direction makes wire rope itself loose, and the elevator internal bearings can be rotated under the effect of wire rope revolving force, plays the effect that discharges wire rope stress.
Rotary drilling rig is rotary shaft oil seal seal failure in slurry environment with the damage pattern major part of drilling rod elevator on the present market; Because rotary drilling rig need enter into mud in the course of the work with the drilling rod elevator, as long as mud touches rotary shaft oil seal, fine particles such as the sandy soil in the mud; Just might get into oil seal lip; Rotation and cause oil seal lip to damage, and mud is got in the elevator cavity, cause the damage of bearing; And then causing elevator not rotate, forfeiture discharges the effect of wire rope stress.
The utility model contentThe problem that the utility model will solve provides a kind of stable performance, long service life, and the anti-sludge-type rotary drilling rig of good sealing effect is used the drilling rod elevator.
In order to address the above problem, the utility model adopts following technical scheme:
A kind of anti-sludge-type rotary drilling rig is used the drilling rod elevator, comprising:
Intermediate has in the said intermediate to carry and draws the chamber;
Top connection, top connection is threaded with intermediate;
Lower contact, lower contact comprise base and the central axis that one connects; Said central axis is positioned to carry and draws the chamber;
Central axis is positioned to be carried an end that draws the chamber round nut is installed, and the position on the central axis between round nut and base is set with several angular contact ball bearings;
Rotary shaft oil seal and anti-mud device are installed between the end of said base and intermediate.
Below be the further improvement of the utility model to such scheme:
Anti-mud device comprises several boss that are arranged on the base, and the end of said intermediate is provided with the groove that several boss on several and the base are sealed and matched one by one.
Further improve: the side near base on the rotary shaft oil seal has the oil sealing opening, is inlaid with the hole that is used for limiting the rotary shaft oil seal axially-movable on the intermediate and uses back-up ring.
Further improve: have in the said top connection with carrying and draw the fueling cavity that the chamber is communicated with, said round nut is positioned at fueling cavity.
Further improve: the junction between top connection and the intermediate is provided with the O RunddichtringO.
During work, carry drawing and fill with lubricant grease in the chamber, when the elevator maintenance is carried out in per tour work; Beat lubricating grease to rotary shaft oil seal place and begin to overflow, overflow part and enter in the anti-mud structure in labyrinth, prevent that because of the labyrinth lubricant grease of mud structure can not throw away because of the rotation of elevator; So lubricant grease plays the effect of sandy soil in the block mud,, also be the water that cleans even mud touches oil sealing; Can not damage oil sealing, thereby guarantee the internal bearings operate as normal.
The utility model adopts such scheme; Can effectively improve the life-span of elevator; Be about 2000 hours the average length of working life of elevator on the market; This elevator can prevent effectively that mud from getting into the inner situation of bearing and taking place, and prolongs the application life of elevator, and the average operation time can reach about 4000 hours.
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
