The bearing below of described test weighted platform is fixed with base.
Between base and bearing, be provided with pre-determined bit test specimen carrying vehicle.
On pre-determined bit test specimen carrying vehicle, with adjustable reducing device, described adjustable reducing device is that two ends link together with the leg axle of pulley, and the place of being coupling is fixed on pre-determined bit test specimen carrying vehicle.
Advantage of the present utility model is as follows:
1, horizontal type structure is convenient to install, and can directly lift; Horizontal type structure is for vertical structure, and because it is longitudinally highly lower, complete machine stability is good, easy to maintenance.
2, load cylinder adopt two can movable barrel type balancing cylinder, cylinder barrel, moves back and forth as piston rod with two guide pillars in diagonal position; Shorten complete machine length compared with common oil cylinder, saved space, and can meet compared with the test specimen of big-length specification.
3, the weight of measured piece, web member and cylinder barrel is born by pre-determined bit test specimen carrying vehicle, has avoided the hydraulic cylinder of Hydraulic Station bear too much unbalance loading and cause leaking.Pre-determined bit test specimen carrying vehicle can be adjusted the locus of test specimen, facilitates test specimen clamping, effectively reduces the working strength of testing crew.
4, adjustable reducing device, can adapt to the test specimen of different size.
5, test drives as symmetria bilateralis tower structure, and compared with the one-sided or asymmetric application of force, the power on test specimen of acting on wants evenly, without angular force, the precision of warranty test.Meanwhile, the power of retroaction on main machine frame is also uniformly distributed, and has effectively extended service life of equipment.
6, test space is large, and purposes is wide, multifunctionality.Except can, to the torture test of single (two) sleeve expansion joint, carrying out unilateral stretching, compression test to sleeve expansion joint, expansion joint, corrugated tube etc. as required.The features such as it is high that the utility model also has degree of control, with low cost, reliable and stable, and practicality is stronger.
