Abstract
Lower sheave fixed mount, comprises support, fixed handle, card key, bolt and nut, two supports and the Y-shaped design of fixed handle, and the end of support is parallel, and support has hole, and hole and bolt adapt, and the two ends of bolt, through support, are fixed with nut; Fixed handle is welded with semicircle card key, the end of fixed handle has axis hole, and its advantage is: the Flange joint of pulley and well head, secure the relative position with well head, cable is slided smooth and easy safely, fixed mount can rotate left and right by a small margin, reduces the stress that cable produces.
Description
Technical field
The utility model relates to a kind of mechanical device, especially a kind of machine tool with not having oil reservoir logging.
Background technology
In oil reservoir logging work, cable is derived from logging truck, by lower sheave and top sheave, passes perpendicularly through the flange of borehole log wellhead, enters in oil well.Top sheave is generally fixed on above hydraulic fluid port by fixed lever, and lower sheave generally adopts movable pulley or is fixed on logging truck, and relative to well head, partially sliding easily appears in the direction of lower sheave, makes the direction of cable unstable.
Utility model content
The purpose of this utility model is avoid the deficiencies in the prior art and provide a kind of lower sheave fixed mount.
The technical solution of the utility model is: lower sheave fixed mount, comprises support, fixed handle, card key, bolt and nut, two supports and the Y-shaped design of fixed handle, the end of support is parallel, and support has hole, and hole and bolt adapt, the two ends of bolt, through support, are fixed with nut; Fixed handle is welded with semicircle card key, the end of fixed handle has axis hole.
The A/F of described support and the thickness of wellhead flange adapt.
The axle of described lower sheave is fixed in the axis hole on fixed handle.
Card key position on described fixed handle and lower sheave adapt.
Compared with prior art, the utility model has the advantages that: the Flange joint of pulley and well head, secure the relative position with well head, cable is slided smooth and easy safely, fixed mount can rotate left and right by a small margin, reduces the stress that cable produces.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is use schematic diagram of the present utility model.
Wherein: 1 is nut, 2 is bolt, and 3 is support, and 4 is fixed handle, and 5 is card key, and 6 is axis hole, and 7 is flange, and 9 is cable, and 10 is lower sheave.
Embodiment
