Abstract
The invention discloses a deep well water tube fishing device. The fishing device mainly comprises a dog plate (5), three clamping jaws (6), an expansion shaft (7), a connecting tube (2) and a limiting sleeve (4). When a water tube (12) and a transmission shaft (10) which fall to the well bottom after being broken are fished, firstly the connecting tube (2) is pulled while the fishing device is placed into a deep well, and a cone on the lower portion of the expansion shaft (7) is inserted into the water tube (12) under the guide effect of the cone for positioning; and secondly, a steel wire rope (1) is utilized for lifting up the expansion shaft (7), the three clamping jaws (6) which are matched with a cone on the upper portion of the expansion shaft (7) and provided with pawl surfaces are driven to shift radially at the same time, and the pawl tips of the clamping jaws (6) are made clamped tightly to the inner wall of the water tube, so that the water tube (12) and the transmission shaft (10) are fished up. The deep well water tube fishing device is convenient and fast to operate, simple and safe in structure, and capable of saving time and reducing cost.
Description
Technical field
The present invention relates to a kind of fishing device, specifically a kind of fishing device of deep-well water pipe.
Background technology
At present, the water source of most of Drinking Water is all the deep well beaten by professional well-digging team, this
The general depth of well all in tens of rice or 100 meters to more than 200 meters, when running in deep-well water pipe and power transmission shaft all
During the special circumstances fractureing, due to too deep in well, complicated, the common maintainer of the situation of conduit failure
The disconnected pipe in deep-well cannot be will be left in and power transmission shaft takes out, the special equipment of well-digging team of specialty can only be asked
Salvaged, so not only water stopping time is long, had a strong impact on life and industrial water, and please specialty be beaten
The cost of drilling team is higher.
Content of the invention
It is an object of the invention to provide a kind of not only quick but also easy device salvaging deep-well water pipe, to solve
The problem certainly proposing in above-mentioned background technology, this apparatus structure is simple and convenient to operate, not only time-consuming
And manpower, and with low cost.
For achieving the above object, the present invention provides a kind of following technical scheme: fishing device of deep-well water pipe,
This fishing device specifically includes that dog plate 5, claw 6, tension shaft 7, connecting tube 2, stop collar 4, gear
Pin 3, tighten cushion rubber 8.Wherein, connecting tube 2 is connected with flange with dog plate 5, and claw 6 is connected to card
On pawl disk 5, tighten cushion rubber 8 and be contained in the upper and lower groove of claw 6, make three claws be fixed on tension shaft
(7), on the conical surface, steel wire rope 1 connects tension shaft 7.During salvaging, hold connecting tube 2, loosen steel wire rope 1,
This gripping mechanism is put in deep-well, using the guiding of tension shaft 7 bottom cone and the positioning of diameter segment,
Insertion water pipe 12 is positioned, and then lifts tension shaft 7 upwards with steel wire rope 1, drives and tension shaft 7
Three of top taper fit carry the claw 6 of the pawl flank of tooth, so that the crown of claw 6 is tightly blocked in water pipe
Wall, thus handle fractures, water pipe 12 and power transmission shaft 10 salvage.
Brief description
Below in conjunction with the accompanying drawings the present invention is described in detail.
Fig. 1 is the overall structure profile of deep-well water pipe fishing device.
Fig. 2 is section of structure during partial enlargement gripping orientation.
Fig. 3 is the view of dog plate 5 and claw 6 part.
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the present invention is carried out clear,
It is fully described by it is clear that described embodiment is only a part of embodiment of the present invention, rather than entirely
The embodiment in portion.Based on the embodiment in invention, those of ordinary skill in the art are not making creativeness
The every other embodiment being obtained under the premise of work, broadly falls into the scope of protection of the invention.
Refer to Fig. 1, this deep well have 100 meters deep, and diameter is little, and down-hole water pipe 12 is by many steel pipes
It is formed by connecting with pipe collar 11, the power transmission shaft 10 in pipe is also to be formed by connecting by pipe collar 9, and every section of axle has one
Individual e axle supporting frame 13 supports, and power transmission shaft 10 bottom is provided with the pump housing 14 and chimney filter 15, the pump housing and water pipe
12 connections, during normal condition, power transmission shaft rotates in pipe, and pumps out water when appearance event by the pump housing
During barrier, water pipe 12 or power transmission shaft 10 rupture, and maintainer is necessary for taking out and changes, but water pipe 12
During the special circumstances simultaneously fractureing with power transmission shaft 10, break-off portion falls into shaft bottom, and is possible to be skewed off to depth
The borehole wall, common maintainer cannot take out.
As shown in Fig. 2 the present invention can solve above-mentioned technical barrier, this fishing device mainly by dog plate 5,
The parts such as claw 6, tension shaft 7 form.Maximum gauge in the middle of described tension shaft 7 should with water pipe 12 in
The one side gap in footpath, in 5 millimeter, plays the role of positioning, the cone angle of bottom taper 30 ° -35 ° it
Between, it is play the guiding role with guaranteeing to stretch in crooked water pipe 12, top cone coordinates card lifting with claw 6
Tight act on, the oblique angle a of its cone and oblique angle a mono- of claw 6 to；Dog plate 5 is arranged on tension shaft 7
In portion；Stop collar 4 and the relative position of backing pin 3 restriction claw 6 and tension shaft 7；Two tighten cushion rubber 8
It is contained in the upper and lower groove of claw 6, makes three claws all the time on tension shaft 7 conical surface, keep closely joining
Close；Connecting tube 2 is connected with flange with dog plate 5；Steel wire rope 1 is connected with tension shaft 7；In salvaging,
Hold connecting tube 2 when descending, loosen steel wire rope 1, the leading of the deadweight by this device and tension shaft 7 lower cone
To stretching into down-hole, until to inside water pipe 12, and by tension shaft 7 diameter segment positioning；Steel is strained when up
Cord 1, loosens connecting tube 2, and tension shaft 7 rises, and drives three claws water pipe of spreading clamping simultaneously 12
Inwall is it is ensured that clamping is reliable, thus reaching salvaging purpose.
Claw 6 shown in Fig. 3, answers overall processing for three, outer surface is processed into pawl, the flank of tooth has high demands firmly
Degree, inner surface carries the conical surface it is desirable to smooth surface and tension shaft 7 cone match, and connecting hole is elongated hole,
Ensure that claw 6 can move radially in water pipe, this material carries out Quenching Treatment, then cuts；Dog plate 5
