Summary of the invention:
The technical problem to be solved in the present invention is to provide the continuous indexing mechanism of a kind of oil drilling ball-throwing type, and this device can realize rotating and then complete the function that continuous rotation is located, side path is located, repeatedly opened and closed to continuous and adjustable continuously by pitching.Overcome existing mechanism not have transposition to realize the deficiency of rotation, Telescopic continuously.
The technical solution used in the present invention is: the continuous indexing mechanism of a kind of oil drilling ball-throwing type, comprises upper shell, ball seat, ball I, ball II, ball III, side lead to housing and lower contact, upper shell, side leads to housing and is connected in turn with lower contact, in upper shell, ball seat is installed, ball seat lower end is against in axle, ball seat and axle can move up and down, the upper enclosure inner wall of ball seat lower end has upper groove and low groove in turn, low groove groove depth is greater than upper groove, axle circumference has side passage flow duct, seal blocks side passage flow duct, seal is connected on upper shell lower end inner wall, side leads on the sidewall of housing upper end and has runner, axle blocks runner, axle outer wall is designed with slideway, side leads on housing and is provided with pin, pin inner opposite end stretches in axle outer wall slideway, axle bottom is set with spring, spring upper end withstands on axle between outer land terrace, lower spring end withstands in lower contact, ball I, ball II, ball III all can set on ball seat, ball I external diameter is greater than ball II, ball II external diameter is greater than ball III.
The invention has the beneficial effects as follows: the present invention can realize rotating and then complete the function that continuous rotation is located, side path is located, repeatedly opened and closed to continuous and adjustable continuously by pitching, improve the automaticity of drilling and repairing well instrument, reduce complicated operation degree, improve construction timeliness.
Accompanying drawing illustrates:
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
Fig. 1 is structural representation of the present invention.
Detailed description of the invention:
As shown in Figure 1, the continuous indexing mechanism of a kind of oil drilling ball-throwing type, comprises upper shell 1, ball seat 2, ball I 3, ball II 4, ball III 5, side leads to housing 11 and lower contact 15, upper shell 1, side leads to housing 11 and is connected in turn with lower contact 15, ball seat 2 is installed in upper shell 1, ball seat 2 lower end is against in axle 6, ball seat 2 and axle 6 can move up and down, upper shell 1 inwall of ball seat 2 lower end has upper groove 7 and low groove 8 in turn, low groove 8 groove depth is greater than upper groove 7, axle 6 circumference has side passage flow duct 9, seal 10 blocks side passage flow duct 9, seal 10 is connected on upper shell 1 lower end inner wall, side leads on the sidewall of housing 11 upper end and has runner 12, axle 6 blocks runner 12, axle 6 outer wall is designed with slideway, side leads on housing 11 and is provided with pin 13, pin 13 inner opposite end stretches in axle 6 outer wall slideway, axle 6 bottom is set with spring 14, spring 14 upper end withstands on axle 6 between outer land terrace, spring 14 lower end withstands in lower contact 15, ball I 3, ball II 4, ball III 5 all can set on ball seat 2, ball I 3 external diameter is greater than ball II 4, ball II 4 external diameter is greater than ball III 5.
The present invention is that steel ball by dropping into three kinds of diameter specifications realizes the rotation of mechanism, flexible and side path opens closing function:
One, original state:
Be illustrated in figure 1 instrument original state, now pin 13 is positioned at the A position of axle 6 slideway.
Two, ball III 5 is dropped into:
In an initial condition, drop into ball III 5, ball III 5 is seated at ball seat 2 under drilling fluid promotes, blocking drilling fluid runner, pressure increase, under the effect of drilling liquid pressure, it is descending that ball seat 2 promotes axle 6 Compress Spring 14, pin 13 is along the slideway relative motion in axle 6 to position B (as shown in Figure 1), now ball seat 2 moves to upper groove 7, ball seat 2 opens, ball III 5 is by ball seat 2, now drilling liquid pressure effect is removed, it is up that spring 14 promotes axle 6, pin 13 relative motion is from position B to position C, now axle 6 rotates 45 ° and relative lower elongated distance L, the side passage flow duct 9 of axle 6 exposes from seal 10, side passage flow duct 9 is communicated with runner 12, wing passage is opened.
Three, ball II 4 is dropped into:
After input ball III 5, drop into ball II 4, ball II 4 is seated at ball seat 2 under drilling fluid promotes, blocking drilling fluid runner, pressure increase, under the effect of drilling liquid pressure, it is descending that ball seat 2 promotes axle 6 Compress Spring 14, pin 13 is along the slideway relative motion in axle 6 from position C to position D, now ball seat 2 moves to low groove 8, ball seat 2 opens, ball II 4 is by ball seat 2, now drilling liquid pressure effect is removed, it is up that spring 14 promotes axle 6, pin 13 relative motion is from position D to position C, in this process, axle 6 completes flexible process, and side path is still opened.
