Described back seat jack device comprises six main top jack, and six main top jack are arranged symmetrically in the left and right sides of shelf.
When the rear pipe attitude of adjustment in real time, after the at the uniform velocity propelling of described small-size jack, the speed of pipe is 5mm/min, for ensureing that rear pipe socket can smoothly insert in front tube faucet slowly.
The invention has the beneficial effects as follows: the high front and back pipe of joint socket required precision near time, combined type jacking splicing equipment enables small-size jack in the iron of U-shaped top, can slowly advance rear pipe, for rear pipe pose adjustment provides the reaction time with comparatively low rate; Simultaneously according to the deviation situation in tube coupling interface real standard direction, by regulating the stroke of four small-size jacks, the attitude after changing in pipe substantially horizontal, the horizontal departure before and after reducing in pipe splicing, makes rear pipe to enter in front pipe by mild socket joint; In tube coupling splicing, back seat main top jack withstands on the iron of U-shaped top all the time, and the Traffic control system for small-size jack provides back seat counter-force, after concatenation construction completes, can advance push pipe with proper rate.
