Specific embodiment
In order that the objects, technical solutions and advantages of the present invention become more apparent, below in conjunction with accompanying drawing and reality
Example is applied, the present invention will be described in further detail.It should be appreciated that specific embodiment described herein is only
Only to explain the present invention, it is not intended to limit the present invention.
It should be noted that when element is referred to as " being fixed on " or " being arranged at " another element, it can
Directly on another element or may be simultaneously present centering elements.It is known as when an element and " connects
In " another element, it can be directly to another element or may be simultaneously present centering elements.
In addition, also, it should be noted that the orientation term such as left and right, upper and lower in the embodiment of the present invention,
Only it is relative concept or be reference with the normal operating condition of product each other, and should not be regarded as having
Restricted.It is described in detail below in conjunction with realization of the specific embodiment to the present invention.
As shown in Figure 1 to Figure 3, the embodiment of the present invention proposes a kind of multi-angle extension test structure, and this is more
Angle extension test structure is used for the multi-angle extension test of measured object, and the measured object can be pulling, also may be used
Think other testers to be tensioned, in the present embodiment, the measured object is specifically described by taking pulling as an example.
The pulling of the present embodiment is referred to and is fixed on aerostatics surface, and the connection on gondola or ground is connected to by rope
Structural member.Specifically, the multi-angle extension test structure can include underframe 1, base fabric 2, ladder 3, fixed
Pulley 4, drawstring 5, strain gauge 6 and power set 7, wherein, base fabric 2 is fixedly installed on 1 frame of underframe
It is interior, the pulling 20 of test to be tensioned is fixedly connected with the base fabric 2;Ladder 3 is inclined and is erected on underframe 1
Ladder 31 with multiple intervals on side, and the ladder 3, is detachably fixed erection on ladder 31 and has and determine cunning
Wheel 4, the interval between adjacent steps 31 be able to can not also be waited with equal, and its individual gap size is according to reality
Depending on needs;One end of drawstring 5 is fixedly connected with pulling 20, and the other end of drawstring 5 bypasses fixed pulley 4
Follow-up reneing is stretched, and is fixedly connected with a side of underframe 1, meanwhile, strain gauge 6 and power set 7 are equal
It is arranged on drawstring 5, and strain gauge 6 and power set 7 is located on drawstring 5 between fixed pulley 4 and underframe
Position between 1 side, thus, during staff's driving power device 7, drawstring 5 is to power set 7
Shortening is gradually tightened up in direction, and tensile force is transferred to pulling 20, so, just can carry out stretching survey to pulling 20
Try, the tensile force numerical value can be tested in real time by strain gauge 6.Also, single extension test is completed
Afterwards, fixed pulley 4 can be dismantled and is attached on the ladder of another height, then be entered in the same way
Row extension test, herein, as the height of each ladder is differed, and fixed pulley 4 is in turn mounted on ladder,
And the two ends of drawstring 5 are located at the both sides of fixed pulley 4, so, the ladder of differing heights causes fixed pulley 4
The height that is located is different, and then when causing 20 extension test of pulling, the pulling 20 that drawstring 5 is pulled is relative to base
The angle of inclination of cloth 2 differs, so, be also achieved that pulling 20 multi-angle (as 0 °, 15 °,
30 °, 45 °, 60 °, 75 °, 90 ° etc.) demand of extension test, so as to improve extension test
Precision.
In the present embodiment, the extension test of pulling 20 is referred to:Whether test pulling 20 may be used in predetermined inclination
Make the reading of strain gauge 6 reach predetermined value to bear predetermined pulling force, i.e. driving power device 7, observe
Whether pulling 20 is pulled off or has damage;Or the institute in the case of predetermined inclination or multiple inclination angles of pulling 20
The ultimate tension that can be born, i.e., continuous driving power device 7, makes the reading of strain gauge 6 constantly increase, directly
In the presence of pulling force it is damaged or breaks to pulling 20, strain gauge when observation pulling 20 is damaged or broken
6 reading.
