Description
Technical field
The present invention relates to a kind of crane runway pick-up unit, belongs to crane runway detection technique field.
Background technology
At modern industry production field, crane has very important status in material handling, and along with the develop rapidly of modernization industry, it is large that the elevating capacity of crane also constantly becomes, meanwhile, the overall dimensions of crane becomes increasing, quantity and also becomes many rapidly.Overhead travelling crane is as an important branch of crane, (so-called " gnawing rail " refers at bridge crane or dolly in operational process in the process of work, to be prone to " gnawing rail " phenomenon, wheel rim contacts with track side surfaces, produce horizontal lateral thrust, cause the frictionalwear of wheel rim and track), meeting reduces the serviceable life of wheel and track " to gnaw rail ", increase running resistance, may burn out motor or twist off transmission shaft, when crane work, noise is large, vibration is large, " gnaw rail " and be in operation the horizontal side force of generation, infringement house beam structure, crane is derailing suddenly under steam, cause great equipment, human casualty accident.Therefore, track being carried out to regular detection and finishing is to ensure that crane safety operation institute is requisite.
Early stage main employing drawn the method such as steel wire mensuration and spirit-leveling instrument method, below the problem of its existence described.To draw steel wire mensuration as example, testing staff must climb to operation on girder, has high risk; Belong to hand dipping, steel wire is also easily hindered hand; Due to steel wire effect of weight, measuring error is larger.This method is sagging because the deadweight of steel wire can cause, need to consider modified value, and wants unit clamp to fix steel wire, needs many people to coordinate just and can complete, and seldom uses at present.Early stage detection method needs reviewer's operation of climbing mostly, has very large danger; Measurement result is by people for reading, and error is larger, particularly in track length and span when larger, the automaticity of equipment is very low, although many factory buildings are still using these methods, seldom use in professional testing agency, can predict these methods will be eliminated.
For the detection of crane runway, domestic scholars has proposed some new methods, mainly comprise laser alignment measurement method and total station survey method, the document of delivering mainly contains " a kind of novel bridge portal crane rail measuring method " of " China Mechanical Engineering " and " research of overhead and gantry cranes track " of " Non-Destructive Testing " etc.
Brightness is high owing to having for laser, concentration of energy, high directivity, monochromaticity are good, and good room and time coherence, aspect measurement linearity, use the laser after collimation to have very large advantage as tangible linear datum, and can obtain higher measuring accuracy.Adopt laser alignment measurement method at measuring distance hour, accuracy of detection is higher, but when track length exceedes 50 meters, laser beam can be subject to the impact of several factors, produces drift, and detection effect is not ideal.
Can obtain a higher precision with total station survey, but there are two disadvantages in existing total station survey method: the one, and need to be by the fixing total powerstation reflecting prism that aims in orbit, operating environment is based upon in the air, survey crew must be climbed on crane runway and detect, operating environment is complicated and dangerous, and because total powerstation volume is large, Heavy Weight, the work of building a station before measurement is very inconvenient.Actual site environment is complicated and changeable, is often not easy to build a station in the air.The 2nd, because need to being fixed on a track, measures total powerstation, in the time measuring another track, often need again total powerstation to be moved on another track and again built a station, this has increased workload and the difficulty of testing undoubtedly.And due in testing process, the position of total powerstation needs mobile, the measurement of two tracks is under different coordinate systems, needs conversion and the unification of coordinate system in the time detecting two track combined parameters, has increased the complicacy of data processing.
