Specific embodiment
The utility model, can technical solution according to the present utility model and actual conditions from the limitation of following embodiments
Determine specific embodiment.
In the utility model, for ease of description, the description of the relative position relation of each component is according to specification
The Butut mode of attached drawing 1 is described, such as：The position relationship of upper and lower, left and right etc. is the Butut according to Figure of description 1
Direction is come definite.
The utility model is further described with reference to embodiment and attached drawing：
As shown in attached drawing 1,2,4, which includes big hook support 6, pulley bracket 7, pulley 10, big hook support
6 and pulley bracket 7 all for frame assembly, pulley bracket 7 is fixedly connected on the lower section of big hook support 6, is set on big hook support 6
The first stud shaft 8 through big 6 left and right frame of hook support is equipped with, the right end of the first stud shaft 8, which is provided with, is fixed on the first stud shaft 8
The first nut 11 on big hook support 6 is provided through the second stud shaft 9 of 7 left and right frame of pulley bracket on pulley bracket 7,
Pulley 10 is arranged on the second stud shaft 9, and the right end of the second stud shaft 9 is provided be fixed on the second stud shaft 9 on pulley bracket 7
Two nuts 12.Big 6 and first stud shaft 8 of hook support forms the gap of a rectangle, this gap is just big with the size of hook
Cause matches, then tightens the first nut 11, so that it may so that the utility model is more clamped securely on hook, when in use,
The cable being exposed at outside well head can be directly wound in pulley bracket 7 on pulley 10, without as before, being wound on hook
On, frictional resistance is significantly reduced, such worker is not only time saving and energy saving in drag cable, but also can extend cable
Service life.
Above-mentioned cable sheave device can be made further optimization and/or improvements according to actual needs：
As shown in attached drawing 1,2,4, big hook support 6 is the rectangle frame that downside lacks lower frame, and pulley bracket 7 is that upside lacks
