Detailed description of the invention
Below by way of the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, 2, the utility model provides a kind of directional well strong magnetic die, comprises outer sleeve 1, is arranged on the magnet assemblies 2 on outer sleeve 1 inwall, is positioned at the gimbal assembly 3 above outer sleeve 1.
Described gimbal assembly 3 comprise be arranged in series lower contact 31, universal joint 32 and top connection 33.
Described universal joint 32 can be multiple, and is mutually cascaded, and selects the structure of a universal joint to the explanation of the utility model structure example in the present embodiment.
Described lower contact 31 is connected with described outer sleeve 1.
The syndeton of described universal joint 32 and described lower contact 31, comprise two universal joint engaging lugs 322 of the cylindrical body bottom being positioned at universal joint 32, be positioned at two lower contact engaging lugs 311 of lower contact 31 upper end, and the cross axle 34 between universal joint 32 and lower contact 31.
Described two universal joint engaging lugs 322 axially extend along universal joint 32, and arrange relative to the axisymmetrical of universal joint 32; Described two lower contact engaging lugs 311 axially extend along lower contact 31, and arrange relative to the axisymmetrical of lower contact 31, and relative to described two universal joint engaging lugs 322 in the circumferential half-twist be crisscross arranged, see Fig. 2.
Described cross axle 34 comprises X that mutual square crossing arranges to axle and Y-direction axle, and its four terminations are inserted correspondence respectively and are arranged on four axis holes 322a, 311a on described two universal joint engaging lugs 322 and described two lower contact engaging lugs 311.
Universal joint in gimbal assembly 32 and described lower contact 31 is connected by cross axle 34, to make between universal joint 32 and described lower contact 31 can along the X of cross axle 34 to axle about relatively rotate, relatively rotate before and after the Y-direction axle of cross axle 34, thus the flexible structure realized between universal joint 32 and described lower contact 31 is arranged
The syndeton of described universal joint 32 and described top connection 33 is identical, shown in Figure 2 with the syndeton of described lower contact 31 with this universal joint 32.
When described directional well strong magnetic die comprises multiple described universal joint 32 of series connection, the syndeton between adjacent universal joint is identical with the syndeton of described top connection 33, lower contact 31 with foregoing universal joint 32.
Described magnet assemblies 2 comprises multiple magnetic links be fixed on described outer sleeve 1 inwall.
In the inner side of described magnet assemblies 2, be also provided with inner sleeve lining 4, described neck bush 4 is the stainless steel cask of magnetic conduction.
The downside of described magnet assemblies 2 is provided with for magnetic links and the spacing baffle ring 5 of neck bush 4, and this baffle ring 5 is the stainless steel ring of magnetic conduction, and the bottom of described baffle ring 5 is provided with aduncate barb 51.
The top of described top connection 33 is provided with helicitic texture (not shown), can be female thread structure, also can be external thread structure.
Directional well strong magnetic die of the present utility model, adopt technique scheme, the all parts in gimbal assembly is connected by cross axle, to make between all parts of gimbal assembly can along the X of cross axle to axle about relatively rotate, relatively rotate before and after the Y-direction axle of cross axle, thus realize arranging the flexible structure of directional well strong magnetic die, comparatively severe subsurface environment can be adapted to, oil stain, dirt and the impact of foreign material on gimbal assembly less, and not easily break down, be easy to cleaning simultaneously, avoid in prior art the defect adopting universal ball structure.
As another kind of embodiment, as shown in Figure 3,4, the inwall of described baffle ring 5 is provided with the baffle ring extension 52 tilted upward, this baffle ring extension 52 entirety is conically shaped structure; The top of described baffle ring extension 52 is set to hatch frame, and described hatch frame extends upwardly to inside described magnet assemblies 2.
By arranging baffle ring extension 52, the iron block be attracted moves upward along the inwall of described baffle ring extension 52, until pass the hatch frame of described baffle ring extension 52.Owing to being subject to the graviational interaction of magnet assemblies 2, iron block can move to the inwall direction of magnet assemblies 2 subsequently, thus avoids iron block to drop away.
In like manner, the inwall of described neck bush 4 is positioned at above described baffle ring extension 52, and be arranged at intervals with multiple neck bush extension 41, described each neck bush extension 41 entirety is conically shaped structure; The top of described neck bush extension 41 is set to hatch frame.
Directly move up to make iron block can be subject to graviational interaction on the inwall of baffle ring extension 52, on the inwall of described baffle ring extension 52, scattering device has multiple guided way 53.
