Cable 29a, 29b have shown movable sheave 16a from capstan winch 25a, 25b respectively around idler sheaves 26a, 26b extend to movable sheave 16a, 16b(figure on framework pulley 27a, 27b and the pillar 11; Do not show movable sheave 16b), and walk around movable sheave 16a, 16b, in order to lifting pillar 11.
Movable sheave 16a, 16b can be mobile at the chassis guide rail 39 of pillar.Fig. 4 D has shown movable sheave 16a, has the wheel 81 that is connected in pulley main body 82.Wheel 81 is mobile at the chassis guide rail 39 of pillar 11.Pin 84 is plugged on pulley main body 82 on the lug 11p of pillar 11 releasedly.Equally, the pin through hole 86 in the pulley main body 82 is releasably connected to pulley main body 82 on the top 43 of base 40.As shown in the figure, movable sheave 16a has the recess 16r for six roots of sensation cable.
Fig. 5 F has shown typically and has turned to (kickover) cylinder barrel equipment 90 that it provides the starting force that moves described top 43 towards down position.This equipment has for the mounting structure 92 that mobile device 91 is installed on the main body 82.Be passed to the top 43 of base via an element 93 from the power of mobile device 91.90 pairs of described tops 43 of steering cylinder cylinder device apply power, moving forward described top 43, thereby cause that some supporting leg 44(is vertical at first) mobile, in order to make they and top 43 angled.
Shown in Fig. 5 A, lifting equipment 28a has lifted A glyph framework 20(as shown in the figure).Supporting leg 21,22,23,24 has extended, and parts are by pin joint or otherwise lock together.A glyph framework equipment is positioned at the position of lifting pillar 11 this moment.
Shown in Fig. 5 B, capstan winch 25a, 25b have lifted pillar 11(by packing up cable 29a, 29b), pillar pivots at strut ends 18a, and the strut ends 18b top 43(that has been connected in base 40 for example utilizes the removable pin that passes in the eyelet that strut ends 18b extends to top 43).Supporting leg 21,22,23 and 24 utilizes the pin that passes the supporting leg part and is locked in extended position.
Two-layer platform 17 moves to the position shown in Fig. 5 B, and remains on the appropriate location by the cable 17a, the 17b that are connected between (cable 17a) between two-layer platform 17 and the pillar 11 and two-layer platform 17 and the halfpace 17c.Two-layer platform 17 can movably be attached to pillar 11(at first for example before the step of Fig. 5 A), perhaps can be connected in pillar 11 at any time.
Shown in Fig. 5 C, movable sheave 16a, 16b at chassis guide rail 39(referring to Fig. 4 A) be moved downward to the position shown in Fig. 5 C, be releasably connected to the top 43 of base 40 then.Pulley 16a, 16b utilize and move up and down by for example auxiliary capstan 70.Utilize any suitable mobile device to move movable sheave 16a, 16b also within the scope of the invention along chassis guide rail 39, include but not limited to hydraulic cylinder equipment, pneumatic linear actuator equipment and/or motor.
Shown in Fig. 5 D, lifting equipment 28a, 28b have made 20 declines (so the angle of cable 29 is suitable, so that capstan winch 25a, 25b can give rise to the top 43 of base 40 position of Fig. 5 E) of A glyph framework.The bottom of lifting equipment is connected in the top 43 of base 40 pivotly.And capstan winch 25a, 25b are seated in the place far away apart from pillar 11, and away from the operation relevant with rig.
Capstan winch 25a, 25b then pack up cable 29, with the top 43 of lifting base 40, shown in Fig. 5 E.In this position, cable 29 is located shown in Fig. 5 E with respect to the part on the top 43, namely avoids the various parts on the top 43, and cable 29 can not hinder movement and the operation on the top 43 like this, also can not hinder the operation on every side of rig, especially pillar.
Shown in Fig. 5 E, for make mobile effectively and lifting force effective, when movable sheave 16a, 16b move down at pillar, when being connected to the top 43 of base 40 then, movable sheave 16a, 16b are connected on the position at top 43 of base 40, compare the center at more close top 43, this position (center shown in Fig. 5 E) with the distance between the end (left end shown in Fig. 5 E) at this position and top 43.Still shown in Fig. 5 E, the A glyph framework remains on the appropriate location between the rig operational period, those cables are attached to and extend between pulley 26a, 26b, 27a, 27b and capstan winch 25a, 25b, and the system that makes is positioned at the appropriate location, with described top 43 and the pillar 11 of descending when needed.The movable sheave assembly moves down in orbit, and the corresponding eyelet on the eyelet on the movable sheave assembly and pillar (wherein removably being inserted with pin) is to it, and wheel keeps being connected with the movable sheave assembly simultaneously.
Inland rig can be dismantled by the step of enumerating above putting upside down.
Shown in each figure, capstan winch 25a, 25b are seated in the place (for example Fig. 1,3) of the drilling well end (platform and pillar) away from rig, like this, compare with the position near the drilling well end of rig, capstan winch, cable and relevant device thereof and parts meet with less corrosion and pollution.
