Working principle introduction:
Precondition is that jarring shell 15 blocks in underground chance, i.e., fixed, pulls up the balance of cable type hydraulic shock device
Shell 2.
Through track as free state to unlocked state when extend principle: as shown in Fig. 1,2,4, when pull-up balances shell 2,
First refractory metal connector 1 moves upwards.Balance shell 2 is threadedly coupled with tube filler axis 10 is accelerated, therefore is also moved upwards.
Accelerate 10 compress energy storage spring 12 of tube filler axis, accelerates cylinder shell 11 so that transmitting the force to, therefore accelerate cylinder shell 11 also upward
Movement.Cylinder shell 11 is accelerated to be threadedly coupled with jarring axis 14, therefore jarring axis 14 also moves upwards.At this point, the first high temperature resistant is golden
The extra through track for belonging to the coiling between connector 1 and the second refractory metal connector 4 is elongated needed for making up instrument elongation and passes through
Logical line.Hydraulic oil in jarring shell 15 pulls up while being squeezed into oil inlet passage 22 by jarring axis 14, and then pushes sealing piston
17 movements, sealing piston 17 push pushing sleeve 16, and then compression reseting spring 13.In this process, jarring shell 15 is to block
It is fixed, therefore the extra perforation of the coiling between third refractory metal connector 18 and the 4th refractory metal connector 19
Line, which is elongated, makes up the required through track of instrument elongation.In the first refractory metal connector 1, it is clipped in retraction rack 1-6 and clamp
Through track in set 1-7 has been clamped, and position is motionless.Second refractory metal connector 4, third refractory metal connector 18, the
Four refractory metal connectors 19 are as 1 function of the first refractory metal connector.
Through track as unlocked state to jarring state when extend principle: as shown in Fig. 1,3,4, continuing to pull up balance shell
When 2, jarring axis 14 and acceleration cylinder shell 11 are moved rapidly upward due to the release of 12 energy of energy-storaging spring, complete jarring movement.
At this time the extra through track of the coiling between third refractory metal connector 18 and the 4th refractory metal connector 19 further by
Elongate, reach its maximum length make up jarring axis 14 act after, through track elongation.And the first refractory metal connector 1 and
The amount that the extra perforation line length of coiling between two refractory metal connectors 4 is elongated is relatively small.In the process, first
In refractory metal connector 1, the through track being clipped in retraction rack 1-6 and clamp set 1-7 has been clamped, and position is motionless.
Through track reseting procedure principle: as shown in Figure 1,2,3, 4, when decentralization balances shell 2, the first refractory metal is connect
First 1 and second Distance Shortened between refractory metal connector 4, the through track of elongation be relaxed coiling again in this position.Accelerate cylinder
Mandrel 10 moves downward, and jarring axis 14 also moves downward, and third refractory metal connector 18 connects with the 4th refractory metal at this time
First the distance between 19 shorten, and the through track of elongation is relaxed coiling.
The flexible solution of the above through track is to make instrument by four refractory metal connectors and own structural characteristics
In elongation process, through track is not pulled off.
