Description
Technical field
The present invention relates to field of oil drilling, be specifically related to safe and reliable unload drill stem limiting mechanism.
Background technology
Top drive drilling is the new technology grown up the eighties in 20th century, and top drives well system to be that unit carries out drilling well with thribble, drastically increases drilling efficiency.But before drilling well starts, first must be connected into thribble by single, top then could be utilized to drive and carry out drilling well.For the thribble automatic connecting system for top drive drilling, by a series of hydraulic operation, the upper and lower offshore boring island of drilling rod can be realized, be connected into thribble and split into single, motion drilling rod stockyard process automation, dramatically reduce well site labor strength.Need within the system to use Horizontal Movement device, in order to complete the upper and lower pipe racking frame of drilling rod, and realize drilling rod in horizontal guide rail and shift near rig floor and the reciprocating motion away from rig floor stroke 10m.When unloading drilling rod, drill rod end is placed on drilling rod transport small car by vertical-lift fixture hand, under the drive of hydraulic wireline winch, then draws drilling rod away from rig floor 10m, upper pipe racking frame.And drilling rod is waited in the process entering pipe racking frame and is easily produced slip on mounting table, breaks drilling rod, if position-limit mechanism is dealt with improperly and also can be worn and torn to drilling rod, affects the application life of drilling rod.
Summary of the invention
Instant invention overcomes the deficiencies in the prior art, there is provided safe and reliable and unload drill stem limiting mechanism, can carry out spacing to the drilling rod be placed on mounting table and bolster sponges cover is also set on stroke limit baffle plate, avoid drilling rod that unnecessary slip collision and wearing and tearing occur, place environment safety and reliability, improve the application life of drilling rod.
For solving above-mentioned technical problem, the present invention is by the following technical solutions: safe and reliable unloads drill stem limiting mechanism, comprise rear end sleeve, front end sleeve, be connected to spring guide shaft, stroke limit block and sponges cover between front end sleeve and rear end sleeve, sleeve one end, described front end cover has Compress Spring front end, the other end connects stroke limit block, on stroke limit block, also cover has sponges cover, the vertical direction of sleeve side, front end also arranges rectangular gripper shoe, multiple installing hole is set on the supporting plate; On the sleeve of described rear end, cover has Compress Spring rear end; Described sponges cover outside is arcuate structure.
Horizontal Movement system is when upper drilling rod, first drilling rod is taken off from discharge frame, then under the promotion of drilling rod travelling car, 10m is shifted near to rig floor, enter vertical-lift frame, give drilling rod vertical-lift fixture hand, when unloading drilling rod, drill rod end is placed on drilling rod transport small car by vertical-lift fixture hand, then under the drive of hydraulic wireline winch, drilling rod is drawn away from rig floor 10m, then drilling rod is placed on mounting table, drilling rod one end props up the stroke limit block that cover has sponges cover, sponges cover can carry out being out of shape according to the difformity of supports drill rods and play the effect of buffering, reduce the fretting wear between drilling rod and stroke limit block.Then, spring guide shaft starts mobile, Compress Spring front end and Compress Spring rear end are all compressed, stable limits drilling rod in position, simultaneously by gripper shoe to front end sleeve with extra support, avoiding producing collision because there is slippage, placing environment safety and reliability, longer service life.
The vertical direction of described gripper shoe is arranged two pieces of parallel horizontal baffles, two pieces of parallel horizontal baffles are vertically divided equally by one piece of vertical baffle, and two pieces of horizontal baffles and one piece of vertical baffle two all arrange fastener, utilize fastener button on the supporting plate.Horizontal baffle and vertical baffle adopt this kind of mode fixing more firm, also can not be separated from gripper shoe even if run into larger impact force, thus its position-limiting action of more stable performance, ensure the safety of drilling rod.
Described stroke limit stop bottom is set to curve slope.Ensureing that it can have Maximum Contact face with needing spacing drilling rod, while increasing stability, reducing the friction between arcwall face and drilling rod, ensureing the intact of drilling rod.
Further, the vertical direction of described gripper shoe is arranged two pieces of parallel horizontal baffles, two pieces of parallel horizontal baffles are vertically divided equally by one piece of vertical baffle.
Further, Compress Spring front end is positioned at the U-shaped chamber that two pieces of parallel horizontal baffles and vertical baffle are formed.Compress Spring front end can be limited in specific scope, avoid Compress Spring front end to compress excessive, damage drilling rod.
Further, described front end sleeve arranges base.
Compared with prior art, the invention has the beneficial effects as follows:
1, drilling rod can limit in position by the present invention, and slippage can not occur and produce collision, place environment safety and reliability, on stroke limit block, also cover has sponges cover, play the effect of buffering, reduce the fretting wear between drilling rod and stroke limit block, prevent environment safety and reliability, improve the application life of drilling rod.
2, horizontal baffle and vertical baffle all adopt extra fastener to fix, and also can not be separated from gripper shoe even if run into larger impact force, thus its position-limiting action of more stable performance, ensure the safety of drilling rod.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure, Reference numeral is expressed as: 1, Compress Spring rear end; 2, spring guide shaft; 3, Compress Spring front end; 4, gripper shoe; 5, stroke limit block; 6, rear end sleeve; 7, front end sleeve; 8, sponges cover; 9, fastener.
