Description
Technical field
The utility model relates to a kind of drilling machine coring apparatus, more particularly, to a kind of oil cylinder times journey push type seabed drilling machine rope
Ask for center device.
Background technique
Seabed drilling machine is that the important probing of the exploration of development seabed resources, seabed engineering geological mapping and scientific research of seas takes
Sample equipment.With continuing to increase for seabed drilling machine drilling depth, for the operating efficiency for improving drilling machine, the coring mode of seabed drilling machine
Also core mode is drilled through from traditional mentioning develop into advanced wire line coring mode.Currently, the cable core tube assembly of seabed drilling machine is big
Part is using drilling power head and salvages the integrated structure type of winch, to solve common drilling power head and salvage to twist
The problem of winch need to accurately follow drilling power head movement is salvaged when the design installation of vehicle fission.When seabed, drilling machine drilling depth is little
When, the required rope capacity for salvaging winch is smaller, and the corresponding outer dimension for salvaging winch and quality are also smaller.But work as sea
After the drilling depth of subdrilling machine reaches the even upper km of rice up to a hundred, due to the sharp increase of required rope capacity, corresponding salvaging winch
Outer dimension and quality will become very big, if continuing using drilling power head and salvaging the integrated structure shape of winch
Formula, it will cause following problem:
(1) since integrated type drilling power head and the outer dimension of salvaging winch are too big, seabed drilling machine need to be increased
The height of power head sliding rail frame is crept into, this will lead to the increase of seabed drilling machine whole height and weight, so that seabed drilling machine is to institute
It carries the A type frame height of lash ship and the bearing capacity of bearing capacity, releasing winch and umbilical cables etc. and proposes requirements at the higher level, meanwhile,
Difficulty of the seabed drilling machine in decentralization and removal process will also be aggravated.
(2) due to integrated type drilling power head with salvaging winch total quality it is too big, motion inertia force and
Its frictional resistance on drilling power head sliding rail frame in motion process will all greatly increase, and cause to creep into power head displacement and bore
Unloading button dynamics during bar screw thread is unloaded is difficult to control accurately, to make the drilling rod (active especially on drilling power head
Drilling rod) service life substantially reduce, difficulty that drilling rod thread is unloaded rises that reliability reduces, operating trouble rate increases, drilling
The abrasion of power head sliding rail increases service life reduction.
However, according to common seabed drilling machine drilling power head design scheme seperated with winch is salvaged, in seabed drilling machine
During drilling and auxiliary operation, since drilling power head is moved up and down in drilling power head sliding rail frame and salvages winch and fix not
Dynamic, the length for creeping into the salvaging wirerope between power head and salvaging winch will be with the movement of drilling power head and constantly become
Change, cause the inner tube of core barrel fishing head relaxation being suspended in drilling power head to fall and salvage wirerope and rope skipping accident occurs,
It needs to carry out salvaging winch frequent positive and negative rotation operation control at this time to ensure inner tube of core barrel salvaging during drilling and auxiliary operation
Head and salvaging wirerope accurately follow drilling power head movement.This not only adds the burden of control system and design difficulty,
The service life (abrasion greatly increases) of wire line coring system is reduced, while also reducing the reliable operation of wire line coring system
Property (easily cause flushing water seal failure and salvage wirerope break failure).
In order to solve the above technical problems, a kind of anxious drilling power head yet-to-be developed and salvaging winch split-type design mounting technique
Rock core during drilling and auxiliary operation can be realized without increasing additional high-precision salvaging winch control in scheme, this scheme
Inner tube fishing head and salvaging wirerope accurately follow drilling power head movement.
Utility model content
