Description
Technical field
The utility model is related to a kind of attack angle mechanism supporting upright column structure, is carried out applied to attack angle mechanism in test chamber
The structure of independent support, also needs the occasion of independent support suitable for other shell intrabody objects.
Background technology
Test chamber is the closing housing for producing experimental enviroment, and run-of-the-mill is larger.Attack angle mechanism is arranged on test section
In, pattern drawing installs the effect with pose adjustment.For the consideration of the influences such as isolation test section vibration, attack angle mechanism needs direct
It is connected with ground, and is disengaged with test section, forms independent supporting construction.Bellows-sheathed is on the outside of supporting construction, it is ensured that shell
Body confined space it is complete.
Due to the presence of the reasons such as test section vibration, thin tail sheep, there is the possibility damaged in bellows.In traditional replacing
, it is necessary to which attack angle mechanism integral hoisting is opened in journey, and bellows could be changed after test section is lifted, workload is very big.
Utility model content
Technical problem to be solved in the utility model：In view of the shortcomings of the prior art, a kind of attack angle mechanism support is proposed
Pillar construction, in the case where not changing experiment piece housing and attack angle mechanism position, completes the replacing of bellows.
Technical solution of the present utility model：
A kind of attack angle mechanism supporting upright column structure, including upper pillar stand, lower pillar stand, bellows and upright post base,
Upper pillar stand is coaxially connected with lower pillar stand, and lower pillar stand is vertically connected on upright post base, upper pillar stand support attack angle mechanism,
The bellows-sheathed that axial stretching and the radial direction changing of the relative positions can be achieved is loaded on upper pillar stand and lower pillar stand, the upper flange of bellows
Be connected with the housing seal of test section, lower flange and the upright post base of bellows are tightly connected, the housing of test section, bellows with
Upright post base formation confined space,
Upper pillar stand, lower pillar stand, upright post base and bellows are with one group of pillar construction is combined into, and attack angle mechanism is by multigroup mutually only
Vertical pillar construction support.
Distance between bellows and upper pillar stand and lower pillar stand is more than the swinging distance of the housing of test section.
Lower pillar stand length is compressed axially rear shortest length more than bellows.
Also include stretching screw, stretching screw is external thread structure, and the upper and lower method of bellows is connected to by adjusting nut
Lan Shang.
The beneficial effects of the utility model：
Opened relative to by attack angle mechanism integral hoisting, bellows replacing is completed after test section is lifted and is compared, this practicality is new
Type is not in the case where changing experiment piece housing and attack angle mechanism position, and the replacing workload for completing bellows is small, safe.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in more detail.
A kind of attack angle mechanism supporting upright column structure, as shown in figure 1, including upper pillar stand 1, lower pillar stand 2, bellows 3 and column
Base 4,
Upper pillar stand 1 and lower pillar stand 2 are coaxially connected, and lower pillar stand 2 is vertically connected on upright post base 4, the support angle of attack of upper pillar stand 1
Mechanism,
Can be achieved axial stretching and the radial direction changing of the relative positions bellows 3 be set in upper pillar stand 1 with lower pillar stand 2, bellows 3 it is upper
The housing 5 of flange and test section is tightly connected, and lower flange and the upright post base 4 of bellows 3 are tightly connected, the housing of test section,
Bellows 3 and the formation confined space of upright post base 4,
Upper pillar stand 1, lower pillar stand 2, upright post base 4 and bellows 3 are with one group of pillar construction is combined into, and attack angle mechanism is by multigroup phase
Mutually independent pillar construction support.
Distance between bellows 3 and upper pillar stand 1 and lower pillar stand 2 is more than the swinging distance of the housing of test section, and lower pillar stand 2 is grown
Degree is compressed axially rear shortest length more than bellows 3.
Also include stretching screw 7, stretching screw 7 be external thread structure, by adjusting nut be connected to bellows 3 it is upper,
On lower flange.
Embodiment
Supported objects 6 are individually supported on ground by supporting construction, are not in contact with big quality housing 5.On bellows
The lower opening flange of flange 3.1 and housing 5 utilizes mode connects for screw, and forms flange sealing structure；Bellows lower flange 3.3 and column
The upper flange of base 4 is connected, and forms flange sealing structure；Bellows 3 participates in the formation of the inner space of housing 5.Using certain
Dismounting order, in the case where not changing housing 5 and the position of supported objects 6, can complete the replacing of bellows.
The Renewal process of bellows 3 is：The connection of bellows upper flange 3.1 and housing 5 is first disengaged, stretching screw 7 is recycled
Compress bellows are to axial limit length, then disengage the connection between upper pillar stand 1 and lower pillar stand 2, then bring up to bellows
Connection between lower pillar stand 2 and upright post base 4 can be disconnected, finally by bellows 3 and lower pillar stand 2 together laterally out of that is,
Old bellows is split out.Old bellows-sheathed will be replaced outside lower pillar stand 2 in the new bellows for being compressed axially limiting length, then
New bellows and lower pillar stand 2 are together moved laterally to former installation site, then lower pillar stand 2 and upright post base 4 are connected into fastening, then
Bellows lower flange 3.3 and upright post base 4 are connected into fastening, then lower pillar stand 2 and upper pillar stand 1 are connected into fastening, will finally be tensed
Screw rod 7 unclamps, and bellows is recovered length before compression, bellows upper flange 3.1 and housing 5 are connected into fastening.
Opened relative to by attack angle mechanism integral hoisting, bellows replacing is completed after test section is lifted and is compared, this practicality is new
Type is not in the case where changing experiment piece housing and attack angle mechanism position, and the replacing workload for completing bellows is small, safe.
Preferred embodiment of the present utility model is the foregoing is only, not for limiting protection domain of the present utility model.
For those skilled in the art, on the premise of not paying creative work, it can make some to the utility model
Modification and replacement, all such modifications and replacement should all cover within protection domain of the present utility model.
