Technical field:
The invention belongs to oil exploration equipment and hang the moving device technical field, be specifically related to a kind of pair of bar reach hydraulic blowout preventer and hang moving device, be applicable to that hanging of the large-scale blowout preventer of oil-well rig move.
Background technology:
Oil-well rig blowout preventer mobile device has three kinds of patterns usually both at home and abroad.(1) driven by power type.Drive power walking wheels by fire proof motor during walking, drive whole blowout preventer and move.Fire proof motor driving ring chain block and roll lifting chain by loop chain cucurbit during lifting.(2) pneumatic pattern.Drive power walking wheels by air motor during walking, drive whole blowout preventer and move.Air motor driving ring chain block and roll lifting chain by loop chain cucurbit during lifting.(3) hydraulic-driven formula.By fluid motor-driven power walking wheels, drive whole blowout preventer and move during walking, during lifting by hydraulic ram by assembly pulley, the steel rope system blowout preventer of slinging.The propulsion source configuring condition of oil-well rig is all depended in the use of three kinds of forms.
With the immediate prior art of the present invention be the applicant's patent of invention " the fluid power blowout preventer mobile devices (ZL200520078442.4) of three times of increments ", adopt the hydraulic-driven formula.Though operating efficiency improves relatively, its oil cylinder stroke is longer, influences working stability, and can not satisfy greater than 100 tons hanging of blowout preventer and move.
Summary of the invention
The objective of the invention is to design a kind of pair of bar reach hydraulic blowout preventer and hang moving device, be applicable to that hanging of the large-scale blowout preventer of oil-well rig move, large-scale blowout preventer can be hung outside rig substructure and move on to well head, or hang from well head and to move on to the rig substructure outside.And oil cylinder stroke is short, and good operating stability can satisfy fully greater than 100 tons hanging of blowout preventer and move.
Technical solution of the present invention: a kind of pair of bar reach hydraulic blowout preventer hangs moving device, has mobile device, the below of described mobile device is hinged with cylinder barrel, have oil cylinder I and oil cylinder II that dividing plate is divided into two symmetries in the described cylinder barrel, fixedly there is the running block I end of the piston rod I of described oil cylinder I, fixedly there is the running block II end of the piston rod II of oil cylinder II, fixed pulley group I and fixed pulley group II are fixedly arranged on the described cylinder barrel, one end of steel rope is fixed on the cylinder barrel, and the other end is walked around the running block I successively, the running block II, be connected with lifting appliance vertically downward after fixed pulley group I and the fixed pulley group II.
The end of the piston rod I of described oil cylinder I is symmetrically fixed with two running block I, the end of the piston rod II of oil cylinder II is symmetrically fixed with two running block II, the bilateral symmetry of described cylinder barrel fixedly has two fixed pulley group I and two fixed pulley group II, one end of two steel ropes is separately fixed on the cylinder barrel, and the other end is walked around the both sides, upper end that are connected lifting appliance after running block I, running block II, fixed pulley group I and the fixed pulley group II of the same side vertically downward respectively successively.
Being centered close on the same horizontal surface of the axis of described piston rod I, piston rod II and running block I, running block II, fixed pulley group I and fixed pulley group II.
The present invention is compared with prior art: adopt double piston-rod to promote two groups of running blocks respectively and finish guiding by two groups of fixed pulley groups, change vertical displacement movement into stretching out motion about double piston-rod.The stroke of piston rod has only 1/4 of sling height, has reduced the length of oil cylinder to greatest extent, and structure is also simplified thereupon, and working stability is improved greatly, and crane capacity promotes significantly, and crane capacity can reach more than 100 tons.
