Abstract
The utility model relates to a tensile test fixture adopting a single cylinder to drive an anchor chain. The tensile test fixture comprises a pedestal, clamping arms, a hydraulic device and push rods, wherein the hydraulic device is fixed on the pedestal through bolts; the cross section of the pedestal is provided with a V-shaped opening, and two side surfaces of the V-shaped opening are respectively provided with open slots; one end of each clamping arm is hinged on each open slot, so that a free end is formed at the other end of each clamping arm; and one end of each push rod is hinged on each clamping arm and the other end of each push rod is hinged on the top end of a piston rod of the hydraulic device. The tensile test fixture disclosed by the utility model has the beneficial effects that the hydraulic device is simplified by simultaneously driving the two symmetrical clamping arms by means of a single hydraulic cylinder and the reliability and operability of the system are improved; and the clamping arms move under the action of the same hydraulic device and are completely symmetric in structure by means of the linkage formed by the piston rod, the push rods and the clamping arms, and the adverse effects on tensile test resulting from asymmetric movement of the clamping arms are avoided.
Description
Technical field
The utility model relates to a kind of single cylinder and drives anchor chain tensile test fixture.
Background technology
The tension test of anchor chain is a ring important in its manufacture process, and the reliability of rig for testing directly affects testing result.At present, the tensile test fixture of anchor chain adopts hydraulic-driven and mechanical self-latching mode more, by two Driven by Hydraulic Cylinder both sides jig arm motions, realizes the clamping to anchor chain.Because the parameters such as the friction force of hydraulic cylinder, leakage rate can be not identical, can cause the both sides jig arm to drive after long-time the use asynchronous, the problem such as clamping is asymmetric detects test and to cause adverse effect.
Summary of the invention
The problems such as it is asynchronous that the utility model can cause the both sides jig arm to drive for the tensile test fixture of present anchor chain is long-time after using, and clamping is asymmetric have proposed that the symmetrical single cylinder of jig arm motion drives anchor chain tensile test fixture in a kind of anchor chain tensile test.
Single cylinder described in the utility model drives anchor chain tensile test fixture, and it is characterized in that: comprise pedestal, jig arm, hydraulic means, push rod, described hydraulic means is bolted on the described pedestal; The section of described pedestal arranges the V-type mouth, and two sides of described V-type mouth all arrange fluting; Described jig arm one end is hinged on the described fluting, so that the other end of jig arm forms free end; One end of described push rod is hinged on the described jig arm, and the other end is hinged on the piston rod top of described hydraulic means.
The number of described jig arm is 2.
Every corresponding described push rod of described jig arm.
Described pedestal is symmetrical along the central shaft of described V-type mouth.
Push rod on the described jig arm is positioned at the jig arm side near 1/3rd places of fluting.
Described jig arm, described push rod are all symmetrical along the central shaft of pedestal.
Before anchor chain carried out tension test, under the driving of hydraulic means, piston rod stretched out, two push rods outwards move about promotion, push rod drives jig arm and opens around rotation, anchor chain is penetrated from the space that the free end of two jig arm forms enter smoothly testing machine, for tension test is prepared; After anchor chain entered, the hydraulic means acting in opposition was regained piston rod, drove push rod and inwardly moved, and push rod pulling jig arm is rotating closed, and the free-ended end face of jig arm withstands a wherein ring outside of anchor chain; Tension tester inwardly draws anchor chain, and the ring that anchor chain is pushed by jig arm also applies inside pressure to two jig arm, and jig arm has the trend of inside rotation, forms self-locking.
The beneficial effects of the utility model are: (1) adopts single hydraulic cylinder to drive simultaneously the jig arm of two symmetries, has simplified hydraulic means, improves system reliability and operability; (2) interlock that forms by piston rod, push rod, jig arm is moved jig arm under the effect of same hydraulic means, the structure full symmetric has been avoided the asymmetric adverse effect to tension test of jig arm motion.
