The special shape section rubber sleeve (1) is arranged on the roller inner shaft sleeve (5) , the roller coat (6) constitutes the flexible roller part (2) on the roller inner shaft sleeve (5), the flexible roller part (2) is arranged into the hole of the swivel (3), the swivel (3) connects with the flexible roller part (2) by the pin (4). Thus, the device is very efficient on energy absorption of impact and vibration, and meets the design demand.
Description
Technical field
The utility model relates to a kind of oil well logging downhole probe triangular structure and I-shaped skeleton roller radial compliance earthquake resistant structure of being used for, specifically, is a kind of skeleton roller radial compliance earthquake resistant structure.
Background technology
Oil well logging downhole probe circuit skeleton is an instrument frame for movement main body, the electronic circuit board that is used to install instruments, various electronic device and physical detecting device.In logging operation, downhole probe circuit skeleton is carrying axially and impact radially (design objective for 〉=50g/11ms) and vibrations (design objective for 〉=3g/5～150Hz), this shock resistance and anti-vibration design to the oil well logging downhole probe has proposed very high request.The present oil well logging downhole probe circuit skeleton that generally uses, its axial shock resistance anti-vibration structure design space is bigger, and structure design adopts axial screw spring shock resistance anti-vibration.Its spring rate F '=11N/mm, design precommpression f=8～15mm, spring prefastening load F=F ' f=11N/mm * 8～15mm=88N～165N.Owing to adopt high-strength thermoforming aluminium alloys trigonometric sum I-shaped skeleton, the skeleton quality reduces 30% approximately, with existing oil well logging downhole probe is example, the skeleton quality is all about 5～9Kg, when the impact that is subjected to 50g/11ms, the contract of skeleton quality and equivalent inertial impact force is 98N～176N, is slightly larger than spring prefastening load 88N～165N, and helical spring can effective absorbing vibration energy of axial deformation and reduction impact force peak value.Have anti-impact force and anti-vibration ability preferably.
And the structure design space of shock resistance radially and vibrations is limited, radial deformation energy-absorbing space is little, has only 0.4～1.1mm (tool housing internal diameter φ 70+0.2mm, instrument skeleton φ 68mm), the structure design of original shock resistance and vibrations has two kinds, a kind of is radially helical spring endergonic structure design, and a kind of is that radially solid rubber roller endergonic structure designs.Because the restriction in structure design space, helical spring designs its rigidity F '≤3 N/mm, too little effectively absorbing vibration energy of spring rate F ' and reduction impact force peak value.And that solid rubber roller endergonic structure designs the value of its rigidity F ' is non-linear for conic section, and at f=0.4～1.1mm, F ' 〉=20～110 N/mm, rubber roll rigidity F ' too greatly can not the absorbing vibration energy and cut down the impact force peak value.
Through investigation and retrieval, at present domestic flexible shock resistance of same radial and the anti-vibration roller frame for movement of also not adopting is made oil well logging downhole probe cage construction.
Summary of the invention
The purpose of this utility model is to provide a kind of skeleton roller radial compliance earthquake resistant structure, the rubber roll of this profiled-cross-section, make its F ' value can reach designing requirement, solved the shock resistance radially of oil well logging downhole probe circuit skeleton and the problem of vibrations effectively.
The utility model be achieved in that comprise profiled-cross-section rubber sleeve 1, flexible rotor block 2, turn 3, bearing pin 4, axle sleeve 5, roller shell 6, profiled-cross-section rubber sleeve 1 is packed on the roller internal axle sleeve 5, roller shell 6 is enclosed within forms flexible rotor block 2 on the roller internal axle sleeve 5, flexible rotor block 2 is packed into and is turned in 3 the hole, turns 3 to be connected by bearing pin 4 with flexible rotor block 2.
Uniform with three rectangular openings of 120 ° of processing on 3 the circumference of turning, respectively have pin-and-hole on the rectangular opening face.
Of the present utility modelly be a little: between the rigidity F ' 10～12N/mm of profiled-cross-section rubber sleeve, its rigidity value is reasonable in design, the precompressed displacement can reach 0.3mm, and antagonism impact endurance test shock energy absorption is favourable, and the displacement f when instrument radially is subjected to extraneous impact and vibrations also can reach 1mm.The precompressed displacement and be hit and the displacement f when shaking all reasonable, the energy absorption when impact and vibrations is very effective, can meet design requirement.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the structural representation of flexible rotor block 2.
The specific embodiment
As shown in Figure 1, by profiled-cross-section rubber sleeve 1, flexible rotor block 2, turn 3, bearing pin 4, axle sleeve 5, roller shell 6 form, uniform with three rectangular openings of 120 ° of processing on 3 the circumference of turning, respectively have pin-and-hole on the rectangular opening face, flexible rotor block 2 is packed into and is turned in 3 the hole, turns 3 to be connected by bearing pin 4 with flexible rotor block 2.
As shown in Figure 2, profiled-cross-section rubber sleeve 1 is packed on the roller internal axle sleeve 5, and roller shell 6 is enclosed within forms flexible rotor block 2 on the roller internal axle sleeve 5.
On instrument circuit triangle or I-shaped skeleton, install and turn 3, at three rectangular openings of uniform 120 ° of processing on 3 of turning, on the three rectangular opening faces parallel, respectively process a φ 5mm pin-and-hole with instrument circuit skeleton axis, each sells a φ 17mm roller, roller inner ring and outer ring are metal material, but between inner ring and outer ring one profiled-cross-section rubber sleeve 1 are installed.Since appropriate design the rubber sleeve profiled-cross-section, rubber sleeve rigidity F ' value is between 10～12N/mm, when the instrument circuit skeleton is packed shell 6 into, control big precompressed (rubber sleeve distortion) by structure design to roller 0.3mm, when instrument when radially being subjected to extraneous impact and vibrations, the instrument circuit skeleton reaches shock resistance and vibrations because the effect of inertia force will continue the distortion of compressing rubber sleeve to release energy.
The profiled-cross-section rubber sleeve 1 roller internal axle sleeve 5 of packing into, pack into together then and form flexible rotor block 2 in the roller shell 6, pack into 3 oil well logging downhole probe triangles and I-shaped skeleton of flexible rotor block 2 set upright revolving body 3, penetrate bearing pin 4, Swelling riveting pin axle 4 constitutes skeleton radially shock resistance and percussion mechanism.
