Detailed description of the invention
Below in conjunction with accompanying drawing illustrated embodiment, the utility model is described in further detail.
Number in the figure is: 1-fixed mount; 2-armstand; 3-oblique arm; 4-V-type groove; 5-reinforce supporting leg; 6-height of landing leg adjusting device; 7-roof fall device; 8-crossbeam; 9-armstand sliding machine; 10-stripper; 11-steady pin; 12-position-limit mechanism; 13-spacing pulley; 14-V-type groove fixed axis; The little axletree of 15-oblique arm; 16-oblique arm steady pin; 17-push rod arrangement for adjusting height; 18-hydraulic motor; 19-draw chain; 20-supporting leg steady pin; 21-supporting leg crossbeam; 22-fixed bar; 23-wellhead assembly; 24-pipe bridge; 25-pipe bridge supporting leg; 26-oblique arm sliding machine.
Equipment is installed:
Bottom fixing frame (1) is put into pithead position, reinforce supporting leg (5) for 4 that launch fixed support (1) both sides, and swing leg arrangement for adjusting height (6) is firm with ground.The pin of armstand (2) and bottom fixing frame (1) is installed, the fixed bar (22) of fixing well head secondary platform, refills and join oblique arm (3) to bottom fixing frame (1) and the pin to armstand (2) top.
Lift operation:
When cutting a little less than pipe bridge position bottom Non-follow control V-type groove (4) runs to, arrange this location status as lower position, tumble an oil pipe in V-type groove 4, now start lifting action, V-type groove (4) armstand sliding machine (9) and oblique arm sliding machine (26) dragging on, automatically the pithead position of specifying is raised to, oil pipe lifting process terminates, after suspension hook drags oil pipe to well head place, start decline process, V-type groove (4) drops to pipe bridge (44) place in the dragging of armstand sliding machine (9) and oblique arm sliding machine (26), operation next time can be carried out, operating process is as foregoing description step.
Operation falls in holder
The holder process of falling is exactly the reverse operating of lifting step, consistent with V-type groove motor performance lifting process process, unlike needs, 2 roof fall devices (7) are adjusted to proper height, make V-type groove (4) in the process declined, strike the chamfered portion of roof fall device (7), automatically the oil pipe in V-type groove (4) is fallen on pipe bridge (24).
Equipment decomposes:
After workover treatment completes, need equipment to disassemble transport, step is as follows:
V-type groove (4) is dropped to lowest part, dismounting armstand (2) and the steady pin on oblique arm (3), then dismantle the steady pin of oblique arm (3) and bottom bracket (1), oblique arm (3) has been removed.
Remove the steady pin of armstand (2) and bottom fastening bracket (1), remove the fixed bar (22) on armstand (2) upper end and well head two-layer platform, armstand (2) has been removed.
Reinforce supporting leg (5) to bottom fastening bracket (1) side for 4 that pack up bottom fastening bracket (1), now this three part being stacked together can hoisting transportation.
