Description
Technical field
The present invention relates to a kind of unhook testing machine.
Background technology
Testing machine, is carried out the instrument verified by its quality or performance design requirement.From definition it can be seen that 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, be adapted to detect the various performances of material.Testing machine is mainly used for measuring material or the physical property of product, such as: the yield strength of steel, tensile strength, toughness, etc..For measuring the namely chemical composition of the chemical property of material, typically it is analyser, is not testing machine.Testing machine is mechanical performance, processing performance, internal flaw and the fine measuring instrument of verification rotating parts dynamic unbalance amount measuring metal material, nonmetallic materials, machine components, engineering structure etc. under various conditions, environment.
In the middle of the process of world's industrial development, testing machine is the inevitable outcome of industrial civilization development, from the point of view of in literal sense, testing machine product was mainly some product before dispatching from the factory to the quality of its product, performance, a kind of instrument of verifying by design requirements, the most typical such as have radial-boom impact tester, electronic tension tester, Mooney viscosity tester and all kinds of analyzer to fall within these categories within.While industrial civilization constantly advances at home, the technology development of testing machine also achieves the achievement attracted attention.
Big multipotency measures metal and nonmetallic materials, engineering structure, machine components characteristic etc. under various conditions, the processing performance finding Related product that can have had very much and the defect etc. of producer's interiors of products thereof, scientific research institution's research and probe new material technology and products thereof new technology when, testing machine has just become an indispensable important instrument.Various various types of testing machine products are widely used in some industrial manufacturing industry departments such as chemical industry, oil, building materials, machinery, shipbuilding, traffic the most also can be occurred at the laboratory of some universities, scientific research office, for developing the future of testing machine, it improves Product Process quality to effective, and product material uses and reduces cost and plays a very important role.
Unhook testing machine is that lifeboat keeps in repair special equipment, development along with Chinese vessel industry, World shiprepair market is to the developing country's transfer including China, and the repairing of lifeboat and test are one of big event of ship survey all the time, but the use of crane and flat car is more nervous in repair enterprise, and the repairing of traditional lifeboat typically requires crane and assisted dismounting, transported and test, therefore, the development of lifeboat repairing special equipment more has meaning.The necessity developed from lifeboat handling trailer and lift heavy, unhook test stand herein and the economic analysis of use, and compare with the service mode in past, according to the simplest design, reach the thought of as far as possible practical effect.Lifeboat and the items of repair job of routine and method are carried out simple introduction, in order to the design making lifeboat handling trailer and lift heavy, unhook test stand is more visual in image, has separately designed corresponding Flash animation and represented its work process.In the design of lifeboat handling trailer, in order to realize the Multi Loading and Unloading Functions of trailer, the baric systerm to Design of Trailer Car, and the main stressed member (such as trailer crossbeam, crossbeam backing pin) of trailer has been carried out force analysis and strength check, the adjustability of the support on trailer crossbeam and the auxiliary of both sides support ball-joint, the backing pin between the supporting plate contacted with lifeboat and the design of lift-bolt, all embody the thought of innovation；And designing without loop and the use of oxygen decompressing table of baric systerm, also fully demonstrate simple design, more practical effect and the consideration to safety.Simultaneously in order to make the design of trailer calculate simpler, use the VBA developing instrument of AutoCAD, write cylinder engine calculation procedure.
Lifeboat lift heavy, unhook test stand design in, lifeboat keel block with reference to boats and ships has carried out the structure 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, motor, reduction box, reel, steel wire rope etc. have been carried out design alternative.
Former lifeboat unhook test must aboard ship be carried out, it is impossible to completes on the coast, therefore will design a kind of testing machine that can the most individually carry out unhook test.
Chinese patent publication No. CN 103048156 A discloses a kind of unhook test detacher, including shell, it is provided with leading screw and the driving means being connected with leading screw in the enclosure, leading screw is provided with two screws, it is respectively equipped with fixture block at two screw opposite sides, it is respectively equipped with arc notch on two fixture blocks, putting hole is formed after said two arc notch split, suspension rod it is provided with in putting hole, described suspension rod is stepped stem, its bigger diameter end diameter is more than putting hole diameter, its miner diameter end diameter is less than or equal to putting hole diameter, miner diameter end in described stepped stem is provided with hook or suspension ring.Owing to using screw-nut to realize the folding of fixture block, folding with convenience is easy, substantially reduces volume, reduces weight, facilitates staff to hang.Owing to fixture block is transversely opened and closed, suspension rod vertically falls, it is to avoid the probability that appearance is stuck, and reliability increases.Realizing breaking off relations owing to using leading screw to drive fixture block to separate, staff can realize in position farther out breaking off relations, and unhook success rate is high, it is not necessary to using welding and cutting tool to remedy, safety increases.The detacher structure of this technical scheme is the most complicated, is unfavorable for being widely used.
Chinese patent notification number CN 201765119 U relates to the unhook test of coal mine inclined shaft people's 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, it is avoided that generation sport car, mancar unhooking tester of inclined shaft includes the unhook steel wire rope that detacher, the single-ended jam plate with detacher are connected, for connecting the connection assembly of main tie on detacher and man car, for connecting the connection assembly of detacher and lifting of winch end portion becket bridle, also include for the iron hoop chain through lifting of winch end portion becket bridle, and being respectively fixed at two ends with for the fixture fixing with man car of iron hoop chain.Present configuration is simple, reasonable, and test effect is good, and preparation is succinct, and safety is high.But its structure is complicated, and practicality is the strongest.
In sum, invention is a kind of easy to operate, and practical unhook testing machine has become as necessity.
