Specific embodiment
Particular content of the invention is described in detail in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, mutual-inserting type variable diameter carries anti-lost pipe clamping device, comprising: three wings slips ontology 1 and double
Wing slips ontology 2 is provided with the first slips connector sleeve on the side of the three wings slips ontology 1 far from double-vane slips ontology 2
3, it is provided with the second slips connector sleeve 4 on the side of the double-vane slips ontology 2 far from three wings slips ontology 1, described three
Wing slips ontology 1 is uniformly arranged there are three the first inserted block 5 on the other side of double-vane slips ontology 2, two neighboring first
It is respectively arranged with the first slot 6 between inserted block 5, the first V-type card slot 7 is provided in first inserted block 5, in the first V
It is respectively arranged with first latching tooth 8 on the first inserted block 5 in type card slot 7, in the double-vane slips ontology 2 close to three wings slips ontology
Be provided on 1 other side with mutually matched second inserted block 9 of the first slot 6, be provided between two the second inserted blocks 9 and position
Mutually matched second slot 10 of the first inserted block 5 in middle part, is provided with the second V-type card slot 11 in second inserted block 9,
The second latch 12, the first latching tooth 8 and the second latch are respectively arranged on the second inserted block 9 in the second V-type card slot 11
12 structure is identical, and the first latching tooth 8 and the second latch 12 are respectively adopted lateral latch and longitudinal latch and are staggered in net
It formats distributed architecture.
Working principle: should will be on the first slips connector sleeve 3 and double-vane slips ontology 2 on three wings slips ontology 1 before operation
The second slips connector sleeve 4 connect axis connection with slips respectively after be connected again with hydraulic system, when operation, should mix up homogeneous tube column 13
It is placed between three wings slips ontology 1 and double-vane slips ontology 2, opens hydraulic system, slips connecting shaft pushes three wings slips ontology 1
It is mobile to center simultaneously with double-vane slips ontology 2, due to the 2nd V in the first V-type card slot 7 and the second inserted block 9 in the first inserted block 5
Type card slot 11 is in V-shape structure, and the first inserted block 5 for being located at middle part is inserted into the second slot 10, and the second inserted block 9 being capable of phase
To in the first slot 6 of insertion, there is guiding role, so tubing string 13 is mobile from trend center, without adjustment；When three wings slips sheet
Body 1 is synchronous with double-vane slips ontology 2 to be continued to center movement, until the first latching tooth 8 and the second V-type card in the first V-type card slot 7
Until the second latch 12 in slot 11 hugs tubing string 13, lateral latch and longitudinal direction is respectively adopted in first latching tooth 8 and the second latch 12
Latch, which is staggered, to be distributed in gridding distributed architecture latch in gridding, and big with 13 contact point multi-panel of tubing string at this time, stress is got over
Big fastening ability is stronger.
Mutual-inserting type variable diameter carries anti-lost pipe clamping device operation instruction:
(1) mutual-inserting type variable diameter carries the assembling and debugging that each connecting portion should be first carried out before anti-lost pipe clamping device use, and latch mechanism is
Whether no locking is flexibly oriented to, and carries out trial operation debugging after inspection again.
(2) mutual-inserting type variable diameter carry anti-lost pipe clamping device using preceding first have to adjust to folder plug-in card watt to it is slotting when whether be in
To in slot, to it is slotting when have it is without hindrance.
(3) mutual-inserting type variable diameter carry anti-lost pipe clamping device preoperation inspection institute card tubing string situation whether with to plug-in card watt size phase
Meet, can to accomplish in card slot when clamping it is non-slip it is tight card be suitable for being preferred.
Repair points for attention:
(1) mutual-inserting type variable diameter carries anti-lost pipe clamping device and to be inspected periodically after a period of use, checks various aspects situation, lock
Tight situation, abrasion condition, connection, then depth inspection is carried out, it timely to be replaced to serious component is worn.
(2) mutual-inserting type variable diameter carries timely when occurring abnormal phenomenon or excessive resistance in anti-lost pipe clamping device use process
Stop card pipe, in time check be to plug-in card watt whether in can to slotting state or whether have foreign matter directly ring to plug-in card pipe imitate
Fruit.
(3) it is carried out when disassembly maintenance by standard technology, latch of the long-time to plug-in card watt is checked.Latch abrasion is big
Should replace in time in order to avoid influencing clamping force, to exit and set back in time after not using, guarantee slips the service life used and
Intensity.
