Abstract
It is a kind of oil drilling technology that drilling well kelly bar enters rat hole device, the shortcoming which overcoming current technology, its structural relation is, one end of rope is connected on compressed air hoist, its other end is connected on kelly bar, and the centre of rope is through rat hole fixed pulley, compressed air hoist pulley；Big rat hole is fixed on drilling floor surface；Meaning of the present utility model is: safe and reliable；Saving manpower, efficiency is high；Only need to transform rat hole mouth on the basis of original rat hole, use cost is relatively low.
Description
Technical field: this utility model relates to a kind of oil drilling technology, and especially drilling well kelly bar enters rat hole device.
Technical background: during oil drilling, needs often to carry out various change working such as making a trip, creep into,
Especially when creeping into and making a trip change working, need kelly bar to draw in big rat hole, originally drew kelly bar to be substantially and lean on
Manpower, minimum needs 3-4 people, laborious and dangerous, is susceptible to personal injury；If using compressed air hoist power-assisted, because
Do not have suitable pulley fixed position once kelly bar can not be drawn in big rat hole.
Summary of the invention: the purpose of this utility model is to provide a kind of simple in construction, and the drilling well kelly bar of easy to operate enters
Rat hole device, the shortcoming which overcoming current technology, the purpose of this utility model is achieved in that it is by kelly bar, big
Rat hole, rope, rat hole fixed pulley, compressed air hoist pulley, compressed air hoist are formed by connecting, and one end of rope is connected to compressed air hoist
On, its other end is connected on kelly bar, and the centre of rope is through rat hole fixed pulley, compressed air hoist pulley；Big rat hole is fixed on
On drilling floor surface.
Described rat hole fixed pulley, it is provided with rope window with big rat hole junction, and rope passes through rope window and side
Drilling rod connects；The height that the position that rat hole fixed pulley is fixed on big rat hole connects on kelly bar greater than or equal to rope；Mus
Hole fixed pulley is higher than the bottom of rat hole angle, rat hole fixed pulley rope window and big rat hole angle in the position that big rat hole is fixing
Centrage, well head straight line to be in.
Meaning of the present utility model is: safe and reliable；Saving manpower, efficiency is high；Only need to be to Mus on the basis of original rat hole
Hole is transformed, and use cost is relatively low.
Accompanying drawing illustrates: Fig. 1 is the structural representation that drilling well kelly bar enters rat hole device, in figure 1, kelly bar 2, big rat hole 3,
Rope 4, rat hole fixed pulley 5, compressed air hoist pulley 6, compressed air hoist
Detailed description of the invention: embodiment 1, this utility model are by kelly bar 1, big rat hole 2, rope 3, rat hole fixed pulley
4, compressed air hoist pulley 5, compressed air hoist 6 are formed by connecting, and one end of rope 3 is connected on compressed air hoist 6, and its other end is connected to
On kelly bar 1, the centre of rope 3 is through rat hole fixed pulley 4, compressed air hoist pulley 5；Big rat hole 2 is fixed on drilling floor surface.
Embodiment 2, described rat hole fixed pulley 4, it is provided with rope 3 window with big rat hole 2 junction, and rope 3 passes through
Rope 3 window is connected with kelly bar 1；The position that rat hole fixed pulley 4 is fixed on big rat hole 2 is greater than or equal to rope 3 at drill with ferrule
The height connected on bar 1；Rat hole fixed pulley 4 is in the fixing position of big rat hole 2 higher than the bottom of big rat hole 2 angle, and rat hole is slided surely
Take turns 4 rope windows and be in straight line with big rat hole 2 angle centrage, well head.
