Description
Technical field
The present invention relates to field of petroleum machinery, be specifically related to clamp firmly drilling tool Fastener.
Background technology
After reform and opening-up, China's rapid economic development, also increasing to the demand of the energy.Drilling well is the tap of petroleum industry, about the investment of drilling well accounts for the half of whole petroleum industry upstream investment.Drilling engineering technical level is directly connected to the success or failure of petroleum exploration and development, also determine development potentiality and the competitiveness of upstream sections of oil business.Pipe pick up and lay down system is as one of mechanized shaftmouth equipment important on marine drilling platform and drill ship, pulling out of hole, achieve clamping to the drilling tool such as drilling rod, sleeve pipe in tripping operation process, promote, transfer and the operation such as translation, realize the automation mechanized operation of pipe racking between well head to discharge frame in drilling process, people is avoided to contact with the direct of drilling rod, and the speed that makes a trip can be accelerated, to reduction Offshore Operation cost, improve operational security and played important function.Existing drilling tool clamping device complex structure, can only the drilling tool of a kind of model of gripping, and easily there is rupturing and depart from fixture when the drilling tool that weight is larger is clamped ask condition, the safety of impact operation.
Summary of the invention
Instant invention overcomes the deficiencies in the prior art, there is provided and clamp firmly drilling tool Fastener, this kind of clamping device structure is simple, can carry out gripping operation to the drilling tool of multiple different model, even if the fixture of clamping heavier-weight also not easily occurs fracture and departs from the situation of fixture, operate safer.
For solving above-mentioned technical problem, the present invention is by the following technical solutions: clamp firmly drilling tool Fastener, comprise translation oil cylinder, clamping cylinder, lift cylinder, put main wall A, put main wall B, gripper jaw and swivel head, two swivel heads are all installed on below gripper jaw and stud sides, put main wall B and put on swivel head that countermure two is arranged between gripper jaw and swivel head respectively; Describedly put main wall A one end and connected by swivel head and put the central point of main wall B, the other end is connected with lift cylinder; The top of described clamping cylinder also arranges running motor, and the vertical direction of running motor also arranges walking rack, and running motor is positioned at column, walking mechanism on the top of column is also arranged, and lift cylinder is arranged on the side of column; Described translation oil cylinder is arranged on the side of column; Described upper walking mechanism is vertically mounted in walking track and upper walking mechanism can slidably reciprocate above.
Translation oil cylinder action drives gripper jaw do in horizontal plane tandem motion, with realize gripper jaw near or away from column; The camber line that lift cylinder retraction realizes gripper jaw short stroke promotes; The walking rack of running motor after the gear reduction on column inwall in meshing column achieves moving up and down of whole upper mechanical arm; Clamping cylinder coordinates meshing tooth bar to achieve the locking of mechanical arm; When upper mechanical arm clamps pawl passes through the opening and closing of two hydraulic clamping cylinders driving gripper jaws, first take down the caging bolt being positioned at installing hole, when realization the clamping of different model drilling tool is promoted, and position fix after, then caging bolt is fixed in installing hole, avoids drilling tool to depart from clamping device.Owing to supporting by putting main wall B and putting countermure between gripper jaw and column simultaneously, strengthen support degree, even if also not easily there is situation about rupturing for heavier drilling tool.
Described put countermure and put main wall B length equal and be parallel to each other.Adopt main wall and countermure synchronously to support, even if outside has the situation that larger pressure also there will not be pressure ring, the crawl of larger drilling tool can be applicable to.
Described translation oil cylinder and lift cylinder lay respectively at column both sides.Can better divide the work operation realizes hydraulic-driven.
Described length of putting main wall A is 1/2 of the length of putting main wall B.This kind of allocative effect the best.
Compared with prior art, the invention has the beneficial effects as follows:
1, structure of the present invention is simple, gripper jaw drives the folding of gripper jaw by two hydraulic clamping cylinders, can the drilling tool of the multiple different model of gripping, and adopt and put main wall B and put countermure and support simultaneously, gripper jaw can bear the situation that heavier drilling tool also there will not be fracture.
2, installing hole is also set on gripper jaw and caging bolt mate-assist gripper jaw carries out position-limiting action, avoids gripper jaw to capture loosely drilling well, occur that situation about coming off occurs, use safer.
