Description
Technical field
The utility model relates to a kind of bridge crane track 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.
