Abstract
The utility model discloses a rotating testing device of a rotating control head, aims to change the low efficiency of the prior testing device. The utility model provides a device with simple hoisting and high fixation testing efficiency, which is composed of a lifting lug, a motor, a reducer, an upper flange, an upright post, a support ring, a hexagonal drive bar, a hexagonal driver and a lower flange. The vertical motor is connected with the reducer through the flange; the hexagonal drive bar is connected with the output part of the reducer through the key; the hexagonal drive bar is connected with the rotating control head through the hexagonal driver; the support ring is welded on the upper part of the upright post. The lower flange is provided with two through-holes which correspond to the two lifting lug threaded holes of the rotating control head and has a bulge acting as an operation platform for workers to stand. The testing device has the advantages of small volume, light weight and is convenient in hoisting. The utility model is directly fixed on the lifting lug of the rotating control head through a bolt, which improves the fixation efficiency, simplifies the testing procedure and improves the testing efficiency for being driven by the motor and slowed down by the reducer.
Description
Technical field
A kind of device that rotatablely moves that provides is provided the utility model, relates in particular to the test unit that a kind of driven in rotation control head bearing assembly rotates.
Background technology
Swivel control head is an equipment of implementing the under-balanced drilling most critical, and major function is can continue to creep into and be with to press to make a trip under well head has the situation of certain pressure.The swivel control head bearing assembly is the parts of swivel control head most critical.The effect of bearing assembly is that the annular space between well head and the drilling tool is carried out motive seal.In the under-balanced drilling process, drilling tool should rotate also and will move up and down, and is the sealed well mouth pressure, should realize that between well head and drilling tool rotary seal realizes reciprocation sealing again, therefore on the swivel control head base bearing assembly must be set.Bearing assembly is rotation and non-rotary community, and be again rotation and non-rotary separatrix: shell body does not rotate, and tightly is pressed on the O-ring seal in the base surface groove by the hydraulic pressure clip, realizes static seal with base by the sealing circle; Two packing units are installed on the inner barrel, and drilling tool penetrates wherein, and the friction force of glue core and drilling tool (or utilizing driver) drives inner barrel and rotates, and realizes reciprocating dynamic seal between the two by the interference fit between glue core and the drilling tool; Realize carrying, rotation, sealing function by bearing pack and motive seal group between the bearing assembly inner and outer shell.
The swivel control head dependability is related to the success or failure of under-balance drilling operation and workmen's life security, so must improve maintenance, maintenance and the required level of service of swivel control head, it is carried out indoor test, particularly its bearing assembly is tested.
The rotation blowout prevention system synthesis test unit of the indoor test of swivel control head bearing assembly use at present, part of appliance is many, bulky, transfer dress inconvenience, especially have big, bulky power station of power and test truss, cause the Installation And Test program complexity of swivel control head loaded down with trivial details, work efficiency is lower.
Summary of the invention
The purpose of this utility model is to overcome the existing low problem of test unit test efficiency, and a kind of rotation test device of swivel control head is provided.
For achieving the above object, the utility model adopts following design proposal:
A kind of swivel control head rotation test device comprises: hanger, motor, speed reduction unit, upper flange, column, support ring, six side's driving stems, six side's driver and lower flanges.Motor top is welded with hanger, motor is vertical being connected with flange with speed reduction unit, and six side's driving stems utilize key to be connected with reducer output shaft, and six side's driving stems are connected with swivel control head by six side's drivers, support ring and column weld together, and are welded with column between upper flange and the lower flange.
Lower flange has and corresponding two through holes of swivel control head hanger threaded hole, and projection is on one side arranged.
The utility model has the advantages that: (1) test unit volume is little, in light weight, and lifting is convenient.(2) only need two through holes of bolt by lower flange to be tightened in the threaded hole of two hangers of swivel control head, thereby test unit is fixed on the swivel control head base, improved installation effectiveness.
Description of drawings
Fig. 1 is the scheme of installation of the utility model test unit.
1. hangers among the figure, 2. motor, 3. speed reduction unit, 4. upper flange, 5. column, 6. support ring, 7. six side's driving stems, 8. six side's drivers, 9. lower flange (flanged pin), 10. coupling bolt, 11. rotary blowout preventers, 12. multi-functional pressure testing devices.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
In Fig. 1, motor 2 is vertical, is connected with speed reduction unit 3 usefulness flanges.Speed reduction unit 3 is connected with upper flange 4 bolts.Be welded with column 5 between upper flange 4 and the lower flange 9.Six side's driving stems 7 utilize key to be connected with speed reduction unit 3 output shafts, are connected with the swivel control head bearing assembly by six side's drivers 8.Be welded with support ring 6 between the column 5, play reinforcement.Can directly lift test unit by the hanger 1 above the motor.
Lower flange has and corresponding two through holes of swivel control head hanger threaded hole, and rotation test device and swivel control head 11 couple together by coupling bolt 10.Before and after the lifting, operating personnel may stand on the projection of lower flange hanger 1 are hung up suspension hook.Test unit has been installed on the multi-functional pressure testing device with swivel control head, can be rotated the control head verticity and detect.
