The rack-and-pinion churn dynamic catwalk of said structure, the drilling tool process of hoisting is:
When needing the drilling tool of conveying to send into V-type drilling tool brace summer 5 by pipe rack or other feeding mechanism, the stock stop 24 of V-type drilling tool brace summer 5 feed end is retracted and is facilitated charging, the stock stop 24 of the non-feed end of V-type drilling tool brace summer 5 stretches out, prevent drilling tool from rolling out V-type drilling tool brace summer 5, after charging, the stock stop 21 of V-type drilling tool brace summer 5 feed end stretches out, and prevents drilling tool from rolling out V-type drilling tool brace summer 5.After charging completes, start coaster motor 8 coaster 3 is pushed forward, coaster 3 is pushed to stopping means 16 place, the brace summer wheel 14 of simultaneous V-type drilling tool brace summer 5 front end is along ramp guide rail 15 upward sliding, Fig. 3 is coaster 3 when moving to stopping means 16 place, the structural representation of the utility model dynamic catwalk.Then coaster motor 8 keeps motionless, and the piston rod of spiral arm oil cylinder 11 stretches out, and drives spiral arm 4 to rotate around bearing pin 2 29, and the brace summer wheel 14 of simultaneous V-type drilling tool brace summer 5 front end is along ramp guide rail 15 upward sliding.Fig. 5 is spiral arm 4 rotation process schematic diagram.Treat that the brace summer wheel 14 of V-type drilling tool brace summer 5 front end slides into " arc-shaped guide rail " place of ramp guide rail 15 front end, the brace summer guide rail 21 of the below of V-type drilling tool brace summer 5 contacts with ramp directive wheel 7, and brace summer 21 relatively ramp directive wheel 7 continues to slide forward.Fig. 6 is the schematic diagram that V-type drilling tool brace summer 5 slides along ramp directive wheel 7.After V-type drilling tool brace summer 5 slides and puts in place, start the chain gearing on V-type drilling tool brace summer 5, drive piston shoes 6 to slide along V-type drilling tool brace summer length direction, drilling tool is pushed near well head, completes the whole process of drilling floor surface on drilling tool.
Drilling tool decentralization process and the drilling tool process that hoists is contrary:
By the crane on drilling floor surface by drilling tool handling to V-type drilling tool brace summer 5, and regulate the position of drilling tool on V-type drilling tool brace summer 5 by piston shoes 6.Then spiral arm oil cylinder 11 is regained, and drives spiral arm 4 to transfer around bearing pin 2 29, plays limited support effect by supplemental support coaster 13 pairs of spiral arms 4.When spiral arm roll wheel assembly 19 contacts with supplemental support coaster 13, spiral arm oil cylinder 11 keeps motionless; Drive coaster motor 8, by engaging with tooth bar 17, band pulley 3 and spiral arm 4 move backward along base rail 20, utilize encoder component 10 to detect after coaster 3 puts in place, move to horizontal level simultaneously after V-type drilling tool brace summer 5.Then rout up to pipe rack or other external device by the material stirring-up mechanism 25 in V-type drilling tool brace summer 5 by drilling tool, whole drilling tool course of conveying completes.
