Abstract
The invention relates to the technical field of test equipment, in particular to a large-sized environmental test chamber pressure-bearing structure, comprising an inner container and a peripheral steel frame; flexible fixed-point connection structures are arranged between stressed points of the inner container and connection points of the peripheral frame, and flexible run-through connection structures are disposed at test holes; each flexible fixed-point connection structure comprises a fixing block, a threaded rod and a flexible connector, the fixing block is disposed on the inner side of the inner container, one end of the threaded rod runs through the inner container and connects with the fixing block, the flexible connector sleeves the threaded rod, and the other end of the threaded rod is connected with the peripheral steel frame; the flexible run-through connection structure comprises left and right sleeves arranged in the corresponding test hole, and a corrugated pipe connected with the left and right sleeves through rivets. At the beginning of mechanism design, stressed points are analyzed, buffer designs are provided between the stressed points and the connection points of the peripheral frame, and the damage of the inner container due to changes of pressure in the chamber is relieved by means of flexible connection.
Description
Technical field
The present invention relates to testing equipment technical field, more particularly, to a kind of large-scale environmental test chamber bearing structure.
Background technology
In environmental simulation experiment, pressure is a very important influence factor, particularly equipment damage aspect is seemed
Become apparent from, the structure design of equipment does not typically possess extensibility, belongs to fixing empty formula structure, once internal generation is swollen
Swollen, no matter being regular again without rule, structure will to be caused with irreversible infringement.Particularly in large-scale environment
The structure design aspect of experimental cabin is particularly important.
Content of the invention
It is an object of the invention to overcoming the shortcomings of above-mentioned technology, and provide a kind of large-scale environmental test chamber bearing structure,
Reduce due to the destructive lesion to inner bag the itself when change of temperature causes inner bag internal pressure to increase or reduces.
The present invention for achieving the above object, employs the following technical solutions:
A kind of large-scale environmental test chamber bearing structure it is characterised in that: include inner bag and peripheral steelframe, on described inner bag
Each stress point and the junction point of described peripheral frame between be provided with flexible fixed point attachment structure, the setting of test hole site is flexible
Run through attachment structure, described flexible fixed point attachment structure includes fixed block, threaded rod and flexible connecting member, and described fixed block sets
Put the inner side in described inner bag, one end of described threaded rod is passed through described inner bag and is connected with described fixed block, and described flexibility is even
Fitting is enclosed within described threaded rod, and the other end of described threaded rod is connected with described periphery steelframe；Described flexibility runs through connection knot
Structure includes the left and right sleeve being arranged in instrument connection and the corrugated tube being connected with described left and right sleeve staking.
Preferably, described flexible connecting member is spring.
Preferably, it is provided with sealing strip between described flexible connecting member and described inner bag.
The invention has the beneficial effects as follows: with respect to prior art, this device force analysis point at the beginning of mechanism's design, each
Individual stress point and the junction point enterprising row buffering design of external frame, are fabricated to flexible fixed point and connect, test bore portion is fabricated to
Flexibility runs through connection, is buffered with flexible connected mode due to the harm to inner bag for the pressure change in cabin.
Brief description
Fig. 1 is the structural representation that in the present invention, flexible fixed point connects；
Fig. 2 is the structural representation that in the present invention, flexibility runs through connection.
Specific embodiment
Below in conjunction with the accompanying drawings and preferred embodiment describe in detail the present invention specific embodiment.As depicted in figs. 1 and 2,
A kind of large-scale environmental test chamber bearing structure, including inner bag 1 and peripheral steelframe 2, each stress point on described inner bag and institute
It is provided with flexible fixed point attachment structure, setting flexibility in test hole site runs through attachment structure, institute between the junction point stating peripheral frame
State flexible fixed point attachment structure and include fixed block 3, threaded rod 4 and flexible connecting member 5, described flexible connecting member is spring.Institute
State the inner side that fixed block is arranged on described inner bag, one end of described threaded rod is passed through described inner bag and is connected with described fixed block,
Described flexible connecting member is enclosed within described threaded rod, and the other end of described threaded rod is connected with described periphery steelframe, when inner bag is sent out
During raw outwards deformation, by compressing compression spring, after inner liner pressure disappears, resetted by spring.During assembling, weld
After inner bag module with fixed block, screw rod of screwing on, put flexible connecting member, place flexible sealing strip, solid with rivet of remaining silent
Fixed, screw rod is screwed on and is welded at steelframe after nut.Further according to design specific requirement, certain heating tape need to be arranged.
Described flexibility run through the left and right sleeve 6,7 that attachment structure includes being arranged in instrument connection and with described left and right set
The corrugated tube 8 that cylinder staking connects.First heating tape is arranged according to design requirement before being attached, passes through reserved instrument connection afterwards,
Place flexible sealing strip in box inside, pulling rivet is fixed using remaining silent.
This device force analysis point at the beginning of mechanism's design, is delayed on each stress point with the junction point of external frame
Punching design, is fabricated to flexible fixed point and connects, test bore portion is fabricated to flexibility and runs through connection, is buffered with flexible connected mode
Due to the harm to inner bag for the pressure change in cabin.
The above is only the preferred embodiment of the present invention it is noted that ordinary skill people for the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
