Abstract
The present invention relates to an anchor chain lacerating machine, which consists of two main cylinders, a frame, sub-cylinders and holding jaws. A movable holding jaw base is arranged on the frame; a pulley is arranged at two ends of the movable holding jaw base; the pulley can move on the frame from left to right; two holding jaws are arranged on the movable holding jaw base; one sub-cylinder is respectively fixed on the frame at the top of two holding jaws. Ends of the two main cylinders are fixed on the movable holding jaw base, and the other ends are fixed on a fixing holding jaw base. Two holding jaws are also arranged on the fixing holding jaw base, one sub-cylinder is respectively arranged at the top of the two holding jaws arranged on the fixing holding jaw base; one end of the sub-cylinder is connected with the holding jaw arranged on the fixing holding jaw base, and the other end is fixed. The present invention can meet the requirement of large tonnage testing anchor chain tension; meanwhile, the anchor chain lacerating machine has the characteristics that the occupied area is small, the equipment is compact, and the efficiency is high and the like.
Description
Technical field: the present invention relates to a kind of mooring tension test for chain cable equipment, particularly relate to a kind of anchor chain lacerating machine.
Background technology: the mooring anchor chain is oceanographic engineering device fixing vitals of mooring in the ocean, is related to the safety of marine oil engineering equipment.The mooring anchor chain lacerating machine is mainly used in the detection of mooring cable being carried out pulling force and tensile strength, existing tension tester adopts single cylinder to load, the tonnage big as needs carries out the detection of pulling force and tensile strength, then must change the bigger oil cylinder of cylinder diameter, this will make the manufacturing cost of tension tester increase, and also makes the mounting structure of testing machine become big simultaneously.
Summary of the invention: have the characteristics of large-tonnage pulling force and octopus compact conformation simultaneously in order to make existing tension tester, the force application structure that mooring cable tension tester of the present invention provides a kind of twin-tub to promote, make puller system have not only that cost is low, the characteristics of compact conformation, can also produce large tonnage pulling force simultaneously.
The technical scheme that the present invention solves its technical matters employing is: anchor chain lacerating machine is made up of two master cylinders, frame, auxiliary oil cylinder, jaws, it is characterized in that: on frame, be provided with movable jaw seat, described movable jaw seat two ends are provided with pulley, pulley can be on frame move left and right, be provided with two jaws on movable jaw seat, the top of described two jaws has an auxiliary oil cylinder to be fixed on the frame respectively; Described two master cylinder one ends are fixed on the movable jaw seat, the other end is fixed on the stationary jaw seat, on described stationary jaw seat, be provided with two jaws equally, two jaw tops that are provided with on the stationary jaw seat are respectively equipped with an auxiliary oil cylinder, the jaw that is provided with on one end of auxiliary oil cylinder and the stationary jaw seat links to each other, and the other end is fixed.The present invention changes original single cylinder force application structure into the twin-tub force application structure, makes its compact conformation, can produce bigger pulling force.Simultaneously in order to reach the synchronous effect of twin-tub, the design adopts the hydraulic proportional servo-control system to constitute closed-loop control, its core is to utilize HN100 proportional controller and displacement transducer, the synchronous error of oil cylinder is controlled in the 3mm, through just satisfying the pulling force and the disrumpent feelings requirement of experiment of big specification mooring cable after such improvement.
The invention has the beneficial effects as follows, can be issued to the needed pulling force of tensile test in compact conformation, the less situation of cylinder diameter, guarantee the synchronous working of twin-tub simultaneously, make mooring cable when doing tensile test, guarantee the accuracy of clip position, and then guarantee the degree of accuracy of experimental data.
Description of drawings: Fig. 1 is the structural representation of anchor chain lacerating machine
1, master cylinder, 2, movable jaw seat, 3. stationary jaw seat, 4,5. jaw, 6, frame, 7, pulley, 8 auxiliary oil cylinders
Embodiment: the present invention is further described below in conjunction with accompanying drawing
In Fig. 1, anchor chain lacerating machine is made up of master cylinder, frame, auxiliary oil cylinder, jaw, on frame, be provided with movable jaw seat, described movable jaw seat two ends are provided with pulley, pulley can be on frame move left and right, be provided with two jaws on movable jaw seat, the top of described two jaws has an auxiliary oil cylinder to be fixed on the frame respectively; Described two master cylinder one ends are fixed on the movable jaw seat, and the other end is fixed on the stationary jaw seat; Be provided with two jaws equally on described stationary jaw seat, be respectively equipped with an auxiliary oil cylinder on the top of two jaws, an end of auxiliary oil cylinder links to each other with jaw, and the other end is fixed.Embodiment, after the chain that needs carry out tensile test is delivered to the appropriate location, jaw on jaw on the stationary jaw seat and the movable jaw seat is fixed the two ends of chain under the effect of two auxiliary oil cylinders, at this moment two oil cylinder promotion activity jaw seats relatively move on the track of frame, chain is carried out tensile test, if be to draw the chain of 2400T to use the pulling force pusher side of single cylinder to need the oil cylinder of diameter as 1800mm equally, then only needing diameter after improving through the present invention is that two oil cylinders of 750mm get final product.But two is twin-tub owing to what adopt, and can they be synchronized with the movement and be directly connected to the accuracy of experimental data when carrying out tensile test, so adopted proportional servo valve to carry out synchro control at this.
