Description
Technical field
The present invention relates to a kind of unhook testing machine.
Background technology
Testing machine, carries out the instrument verified by its quality or performance design requirement.As can be seen from definition, every instrument carrying out verifying for quality or performance can be called testing machine, the product of testing machine constantly bringing forth new ideas, improve, perfect, the various performances of test material can be adapted to.Testing machine is mainly used for the physical property measuring material or product, such as: the yield strength of steel, tensile strength, toughness, etc.For measuring the namely chemical composition of the chemical property of material, being generally analyser, not being testing machine.Testing machine is the fine measuring instrument of mechanical property, shop characteristic, inherent vice and the verification rotating parts dynamic unbalance amount measuring metal material, nonmetallic materials, mechanical component, engineering structure etc. under various condition, environment.
In the middle of the process of world's industrial development, testing machine is the inevitable outcome of industrial civilization development, in literal sense testing machine product mainly some product before dispatching from the factory to the quality of its product, performance, a kind of instrument of verifying by designing requirement, the most such as have radial-boom impact tester, electronic tension tester, Mooney viscosity tester and all kinds of analyzer also to belong within these categories.While industrial civilization constantly advances at home, the technical development of testing machine also achieves the achievement of attracting attention.
Large multipotency measures metal and nonmetallic materials, engineering structure, mechanical component characteristic etc. under various conditions, the shop characteristic finding Related product that can have very much and the defect etc. of producer's interiors of products thereof, when scientific research institution's research and probe new material technology and products thereof new technology, testing machine has just become an indispensable important instrument.Various various types of testing machine product is widely used in some industrial manufacturing industry departments such as chemical industry, oil, building materials, machinery, shipbuilding, traffic and also can occurs in the laboratory of some universities, scientific research office simultaneously, concerning developing the future of testing machine, it improves Product Process quality to effective, and product material uses and reduces costs and plays a very important role.
Unhook testing machine is survival craft maintenance specialized equipment, along with the development of Chinese vessel industry, World shiprepair market is to the developing country's transfer comprising China, and the repairing of survival craft and test are one of big event of ship survey all the time, but the use of crane and flat-bed trailer is more nervous in repair enterprise, and the repairing of traditional survival craft needs crane to have assisted dismounting, transport and test usually, therefore, the development of survival craft repairing specialized equipment has meaning more.Herein from survival craft handling trailer and lift heavy, the necessity of unhook test stand development and the economic analysis of use, and compare with the service mode in past, according to simple design as far as possible, reach the thought of as far as possible practical effect.Simple introduction has been carried out to the items of repair job of survival craft and routine and method, in order to make survival craft load and unload trailer and lift heavy, unhook test stand design more visual in image, devise corresponding Flash animation respectively and represent its course of work.In the design of survival craft handling trailer, in order to realize the Multi Loading and Unloading Functions of trailer, the baric systerm to Design of Trailer Car, and force analysis and strength check have been carried out to the main stressed member (as trailer crossbeam, crossbeam backing pin) of trailer, the design of the spherical connection between the supporting plate that the adjustability of the support on trailer crossbeam and the supplemental support of both sides contact with survival craft, backing pin and lift-bolt, all embodies the thought of innovation; And the use without loop design and oxygen decompression table of baric systerm, also fully demonstrate simple design, more practical effect and the consideration to safety.Simultaneously in order to make the designing and calculating of trailer more simple, adopting the VBA developing instrument of AutoCAD, having write cylinder engine calculation procedure.
In the design of survival craft lift heavy, unhook test stand, survival craft keel block with reference to boats and ships has carried out the structural design of test stand, rotatable test stand, the test for lifeboat that can meet different size requires: according to rising or falling speed and the weight of test for lifeboat, determine the transmission scheme of test stand, design alternative has been carried out to motor, reducer casing, reel, wire rope etc.
Former survival craft unhook test must aboard ship be carried out, and can not complete on the coast, therefore will design a kind of testing machine that can carry out separately unhook test on the coast.
Chinese patent publication No. CN 103048156 A discloses a kind of unhook test detacher, comprise shell, the drive unit being provided with leading screw in the enclosure and being connected with leading screw, leading screw is provided with two screws, fixture block is respectively equipped with at two screw opposite sides, two fixture blocks are respectively equipped with arc notch, putting hole is formed after described two arc notch splits, suspension rod is provided with in putting hole, described suspension rod is stepped stem, its bigger diameter end diameter is greater than putting hole diameter, its miner diameter end diameter is less than or equal to putting hole diameter, hook or suspension ring are provided with at the miner diameter end of described stepped stem.Due to the folding adopting screw-nut to realize fixture block, folding with convenience is easy, substantially reduces volume, reduces weight, facilitate staff to hang.Due to the horizontal folding of fixture block, suspension rod vertically falls, and avoids and occurs stuck possibility, and reliability increases.Drive fixture block to be separated owing to adopting leading screw to realize breaking off relations, staff can realize breaking off relations in comparatively distant positions, and unhook success ratio is high, and without the need to using welding and cutting tool to remedy, security increases.The detacher structure of this technical scheme is too complicated, is unfavorable for widely using.
Chinese patent notification number CN 201765119 U relates to the unhook test of coal mine inclined shaft people car and vertical cage, specifically a kind of mancar unhooking tester of inclined shaft.Carrying at people's car weight breaks off relations in test at full speed, once arresting agency is malfunctioning, when can not realize embracing rail, can avoid sport car occurs, mancar unhooking tester of inclined shaft comprises detacher, the single-ended unhook wire rope be connected with the jam plate of detacher, for connecting detacher with the coupling assembling of main tie on man car, for being connected the coupling assembling of detacher and lifting of winch end portion becket bridle, also comprise for the iron hoop chain through lifting of winch end portion becket bridle, and the two ends of iron hoop chain are fixed with respectively for the fixture fixing with man car.The present invention is simple and reasonable for structure, and test effect is good, and preliminary work is succinct, and security is high.But its complex structure, practicality is not strong.
