Description
Technical field
The utility model relates to puller system technical field, especially a kind of open type route-variable puller system.
Background technique
Currently, puller system mainly has decanter type and open type.Decanter type puller system is located among concrete melt pit, puller system
Stress building is undertaken by concrete, and structure is simple, but concrete melt pit length, width and height immobilize, and are tested the size-constrained of building.
Open type puller system is rest on the ground, and carries pulling force by longitudinal and cross beam, and structure is complicated, and the width generally constructed can be beyond drawing
The width of power machine, some puller system axial spacings are adjustable, adapted to the test of large scale building significantly.
The loading method of most of puller systems is hydraulic loaded.Tensile testing machine is generally divided into two parts, and a fixation has
It can also move integrally, other end is scalable oil cylinder.When test, building is separately fixed at both ends, and the contraction of telescopic oil cylinder carries out
Load test.
There is also following deficiencies for the puller system of the prior art:
(1) all there is the nonadjustable problem of pulling force stroke in current puller system, and the building big to deflection is unable to complete examination
It tests.
Puller system once manufactures completion, and the collapsing length of oil cylinder just secures, and the maximal dilation length of oil cylinder determines structure
The maximum deformation quantity built, the i.e. stroke of puller system.The maximum deformation quantity of general metal building, weldment, wirerope etc. is basic
On in oil cylinder maximal dilation length range.And the suspender belt big for flexible deformations such as cotton cord, nylon rope, cordage, deformation
Amount is big, and oil cylinder full retraction suspender belt does not also reach maximum load-carrying capacity.
(2) stretching displacement can not be surveyed.
Current puller system is substantially the loading device of a static force, can only measure that how much power can break work
Whether workpiece damages in the case where part and given pulling force, cannot measure the stroke of oil cylinder, cannot measure the change of measured workpiece
Shape amount cannot provide the relationship of workpiece stress and deflection.
(3) support of workpiece is placed inconvenient.
The pull head of puller system has a certain distance from the ground, and different workpiece sizes is different, and when test should be as far as possible by workpiece
Impact direction and the direction of pull action cylinder keep coaxial, however current puller system or directly by workpiece placement ground,
It is supported with an iron shelf, it is extremely inconvenient.
(4) protection is not broken.
Since workpiece does not support, can fall ground after breaking, and ground is caused to damage, and some components can also fly out.
(5) there is no step-up system.
Puller system once designs and produces completion, and the pulling force of pull action cylinder determines that pulling force cannot increase again, for pulling force
More than the workpiece of oil cylinder pulling force, can not test.
(6) shield is mobile inconvenient.
Open type puller system majority has shield, however many shields are too long, and long shield movable type is usually
Meeting left and right is asynchronous or moves motionless or twisting, causes test efficiency decline.

Step 7: starting pull test, high pressure liquid pressure oil is passed through retraction oil pipe 12, and pulling piston bar 16 bounces back, load examination
Test beginning, the displacement of 11 real-time detection pulling piston bar 16 of simultaneous displacement sensor, the stopping when reaching setting displacement；Work as retraction
Displacement is up to maximal dilation amount, and load value has not yet been reached when testing setting value, shows that the elongation for being tested workpiece is excessive,
It has been more than single stretching travel, has can star stroke compensating device 2, stroke compensating device 2 drives pulling force screw rod 1 to be displaced outwardly,
Workpiece will be tested to another side stretching, stretching travel is increased, if single compensation is not enough, multiple stroke benefit can be carried out
It repays, until stretching travel meets the test of subject workpiece；
Step 8: during test the case where the real time monitoring of video monitoring 5 subject workpiece, when occurring abnormal, can and
When stop test；
Step 9: the size of load passes through pressure sensor 3 in real time and is acquired during test, setting also can achieve
Stop pull test when load value, the data of acquisition can be saved with the pattern of data and curve graph.
Step 10: using reinforced beam 10 and its group when the drag load of subject workpiece is greater than the design value of pull action cylinder 15
Part changes the multiplying power of tensile machine, in the case where not changing the maximum pull of pull action cylinder 15, increase subject workpiece by
Power.
Step 11: after the test, Lifting carrying platform is leveled to ground, to be tested the disassembly of workpiece.
Above description is the explanation to the utility model, is not the restriction to utility model, defined by the utility model
Range is within the protection scope of the utility model referring to claim, can make any type of modification.
