Embodiment
A kind of converter oxygen gun is arranged with fixed ring 2 and detection ring 3 referring to Figures 1 and 2, including gun body 1 in gun body 1.Gu
Determine ring 2 and gun body 1 is interference fitted, detect ring 3 and 1 clearance fit of gun body, and detects the lower section that ring 3 is fixed on fixed ring 2.Oxygen rifle
The lifting and fixation for realizing oxygen rifle by lift cart during use, detect ring 3 and lift cart is fixed, and reduce rifle
To the influence of detection ring 3 when body 1 tilts.Several support rods can be set between lift cart and the lower end surface of detection ring 3, it will
The both ends of support rod are fixed with lift cart and detection 3 screw of ring respectively.In order to reduce temperature when gun body 1 works to fixation
The damage of ring 2, the inner sidewall of fixed ring 2 are provided with thermal insulation layer, the preferred aerogel blanket of the material of thermal insulation layer in the present embodiment.
Referring to Figures 1 and 2, several detection devices are provided between fixed ring 2 and detection ring 3, detection device is able to detect
Whether gun body 1 is tilted out.Any detection device includes gravitation ball 5, displacement sensor 61 and connects with displacement sensor 61
The display 62 connect.Whole gravitation balls 5 are arranged at the lower surface of fixed ring 2, and pass through between gravitation ball 5 and fixed ring 2
Flexural pivot chain link enables gravitation ball 5 that multidirectional rotation occurs around its hinge joint between fixed ring 2.Whole
The minimum point of gravitation ball 5 is respectively positioned in same level, and the hinge joint of whole gravitation balls 5 and fixed ring 2 is respectively positioned on same circle
The distance of Zhou Shang, the centre of sphere to the detection ring 3 of any gravitation ball 5 are identical, so first between whole gravitation ball 5 and detection ring 3
Beginning distance value is identical.
Referring to Figures 1 and 2, the upper surface for detecting ring 3 offers several grooves, and whole grooves is correspondingly arranged at gravity
Ball 5 is located at the orthographic projection of detection ring 3.Displacement sensor 61, any displacement sensor 61 are fixedly installed in any groove
It is correspondingly arranged with the position of gravitation ball 5, so as to detect variation of the gravitation ball 5 relative to the distance of detection 3 upper surface of ring.
Any displacement sensor 61 is all reserved with identical distance, the distance in the present embodiment between corresponding gravitation ball 5
It can specifically be set according to practical situation.Several displays 62 are provided in gun body 1, display 62 and corresponding displacement pass
Sensor 61 is electrically connected, thus the distance between display distance sensing and gravitation ball 5 value.Displacement sensor 61 is preferred in the present embodiment
Magnetostrictive displacement sensor 61, the electronic room of sensor is interior to generate current impulse, which transmits in waveguide, from
And a circumferential magnetic field is generated outside waveguide, when the magnetic field and cover the movable magnet ring generation on waveguide as change in location
Magnetic field intersection when, the mechanical wave pulse signal of strain can be generated due to magnetostrictive effect, in waveguide, this is strained
Mechanical wave pulse signal is transmitted with fixed speed of sound, and quickly detected by electronic room.Since this strains mechanical wave
Pulse signal in waveguide transmission time and movable magnet ring between electronic room at a distance from it is directly proportional, by time of measuring,
It can highly precisely determine this distance.It also can choose other kinds of sensor simultaneously.Because of displacement sensor 61
The prior art is belonged to the working principle of display 62 and mutual connection relationship, therefore details are not described herein.
Referring to Figures 1 and 2, in order to realize the multi-faceted detection to gun body 1, whole gravitation balls 5 is uniformly arranged.Simultaneously
It is convenient for analyzing the direction of the deflection of gun body 1 by the detection device being uniformly arranged.When gun body 1 deflects, it is set in gun body 1
On fixed ring 2 can also deviate identical angle accordingly, gravitation ball 5 of the ball-joint at this time below fixed ring 2 is in its gravity
Under the action of can rotate at its hinge joint with fixed ring 2, at this time because detection ring 3 and lift cart are fixed, examine
Survey ring 3 can still be maintained horizontally disposed；Thus the pressure of each gravitation ball 5 and detection 3 corresponding point position of ring can be because of fixed ring 2
Rotation and change.The distance change that the displacement sensor 61 being correspondingly arranged at this time with gravitation ball 5 will test is changed into output
Signal is transferred to display 62, thus whether may determine that gun body 1 according to the variation of the distance value of each display 62 display
Run-off the straight.The change value of pressure that also can analyze each display 62 simultaneously obtains the general offset direction of gun body 1.It needs
Bright, even if gun body 1 shifts in actual operation, offset is also smaller, and the amplitude of the rotation of gravitation ball 5 is smaller,
Because without misplacing completely during fixed ring 2 rotates with displacement sensor 61.
Referring to Fig. 2, restraining position ring block 4 is arranged in gun body 1, stop collar 4 and gun body 1 are interference fitted, and stop collar 4 can limit inspection
Survey the maximum distance that ring 3 slides downwards.After releasing the fixation of detection ring 3 and lift cart, effect of the detection ring 3 in its gravity
Lower sliding downwards, until being contacted with stop collar 4.In order to reduce detection ring 3 and stop collar 4 contact when impact force to be placed on inspection
The damage of the displacement sensor 61 inside ring 3 is surveyed, the upper surface of stop collar 4 is provided with buffer stopper 7, can buffer and absorb portion
Divide impact force.In order to further mitigate the impact force between detection ring 3 and stop collar 4, set between stop collar 4 and buffer stopper 7
Several elastic components 71 are equipped with, the both ends of whole elastic components 71 are fixed with stop collar 4 and buffer stopper 7 respectively.The present embodiment is hit by a bullet
The property preferred spring of part 71.
Referring to Figures 1 and 2, it is provided with protective cover in gun body 1, the detection of fixed ring 2, detection ring 3 and whole can be filled
Covering is set inside it, to reduce influence of the external environment to testing result.The material of protective cover is excellent in the present embodiment
Select suprasil.Protective cover includes the first protective cover 81 and the second protective cover 82, and the first protective cover 81 and the second protective cover 82 are right
Claim setting, be capable of forming guard space after the first protective cover 81 and the cooperation of the second protective cover 82, and the shape of protective cover can be with
For any one in sphere, cuboid and square etc..First protective cover 81 and the lateral wall of gun body 1 are fixed, the second protection
Cover 82 and the first protective cover 81 are detachably connected.The first protective cover 81 can be more by welding, screwing etc. in the present embodiment
Kind mode realizes the fixation of itself and 1 lateral wall of gun body.Second protective cover 82 and the first protective cover 81 can be solid by fastening screw
Fixed, the fixation of the first protective cover 81 and the second protective cover 82 for convenience, the first protective cover 81 and the second protective cover 82 mutually lean on
Close end face, which is extended, flange, can be realized consolidating for the first protective cover 81 and the second protective cover 82 by fixing two flanges
It is fixed.
Referring to Fig.1, for the ease of observe each display 62 pressure value variation, by whole displays in the present embodiment
Device 62 is each attached on protective cover.Each display 62 can also be fixed on to the lower end of gun body 1, consequently facilitating observation and note
Record.
