Description
Technical field
The present invention relates to a kind of suspension hook property test platform, especially a kind of large-tonnage suspension hook loads with rotating property test bed.
Background technology
Large-tonnage suspension hook group in use some Problem of Failure may occur, and these lost efficacy and all will produce bigger influence to the usability of suspension hook, also can produce potential safety hazard to the security performance of suspension hook operation.For example, the change that the suspension hook opening degree in use occurs is big, the flow of the wearing and tearing of dangerouse cross-section, bearing poor fit, suspension hook, reverse, and the disconnected hook that causes of suspension hook essential problem etc.Though human factor has been had a lot of preventive measure, by literature search, report did not also appear in the property test platform of suspension hook exploitation at home substantially.The suspension hook of some little tonnages can simply be tested by some large-scale tension test platform or bracket loading test platforms, utilize resistance strain gage that the performance of suspension hook is done simple measurement in the test, but these testing tables all are by motor-driven mostly, motor-driven testing table has certain limitation, maximum shortcoming is exactly that power is little, loading force is little, usually can be above 10 tons, so, the large-tonnage suspension hook can't provide some performance reference datas by these testing tables, thereby can not verify its performance, can only verify by operation on the spot, like this, security just is greatly diminished.
Also relative less with manufacturing abroad to the design of this type of test platform, though the test platform of exploitation can have the experimental performance of heavy load, for large-scale or superhuge, similar 300 tons of testing programs with hook, still relatively more rare.In addition, " the industry investment analysis of 2010-2015 China Construction Machinery and the prospect prediction address " of up-to-date issue shows, since 2009, China has become the manufacturing center of world's crane, and 25 tons to 100 tons hoisting device has occupied dominant position in the world market.But in high-end product market more than 300 tons, a lot of enterprises of China also fail to realize entering in batches.
Summary of the invention
The present invention will provide a kind of large-tonnage suspension hook property test platform, is used to solve the technical matters of the combined test of large-tonnage suspension hook mechanical property.
For achieving the above object, technical scheme of the present invention is achieved in that
A kind of large-tonnage suspension hook property test platform, comprise runner assembly, the charging assembly that place respectively the runner assembly both sides is characterized in: runner assembly comprises pedestal, turntable, the wire rope Connection Block, the hydraulic clamp assembly is connected with turntable above the pedestal, be fixed with the wire rope Connection Block on the turntable respectively, the wire rope Connection Block connects wire rope by the bolt that passes its center, is fixed with two hydraulic cylinders of hydraulic clamp assembly on the turntable; Charging assembly comprises mounting platform, and jack pad assembly, lifting jack, I-beam, supporting seat, jack pad assembly are fixed on the mounting platform of bottom, and lifting jack is installed in the jack pad assembly, on the top of lifting jack through the fixedly connected supporting seat of I-beam; Connect by back shaft between the supporting seat on two charging assemblies.
Runner assembly also comprises rotating shaft, driven synchronous pulley, motor, be with synchronously, on, following cylindrical roller thrust bearing, axle sleeve, flat key, the active synchronization belt wheel, pulley sheaves flexibly connects by last cylindrical roller thrust bearing between turntable and the pedestal, and cylindrical roller thrust bearing was connected with pedestal under rotating shaft was passed through, fixedly connected with turntable in the rotating shaft upper end, the rotating shaft bottom is equipped with motor by the fixedly connected driven synchronous pulley of axle sleeve in the pedestal 1, connects the active synchronization belt wheel by flat key on the motor output shaft, and active synchronization belt wheel bottom is connected with motor output shaft with wheel disc, is connected by synchronous being with between active synchronization belt wheel and the driven synchronous pulley.
The invention has the beneficial effects as follows:
1, the present invention is by the combination of four separate type synchronous hydraulic lifting jack and wire rope Connection Block, formed the synchronous value-added tax function of testing table, use experimental provision that this mechanism combines and can carry out comprehensive load test to the suspension hook group and detect, comprise loading force detection, load the detection of deformation, suspension hook ess-strain etc.
2, the present invention realizes rotating the test function that requires of dirigibility by motor, synchronous pulley and rotating disk, has formed a cover turntable, has clamped unitized construction, to be suitable for the test of the suspension hook gib head being rotated dirigibility.Can make experimental provision when testing by this structure, needn't carry out adjustment mechanically, just can be implemented on the stress state in the process, when rotating the suspension hook gib head, gib head rotates the test function of dirigibility at random.
