Embodiment
As shown in Figures 1 to 4, the utility model crane girder span on-line measurement device comprises laser range finder 3, launcher 1 and acceptance frame 2;
Described launcher 1 comprises the first leveling board 11, side shield 12, location-plate 13 and two piece of first back up pad 14, described side shield 12 is vertical at the end face of described first leveling board 11 side, described location-plate 13 is vertical at the bottom surface of described first leveling board 11 opposite side, described two piece of first back up pad 14 interval vertical is located at described first leveling board 11 bottom surface, and described location-plate 13 is highly greater than the height of described two piece of first back up pad 14;
Described acceptance frame 2 comprises reflecting plate 21, second leveling board 22 and two piece of second back up pad 23, described reflecting plate 21 is vertical at described second leveling board 22 side, described second leveling board 22 is positioned in the middle part of described reflecting plate 21, described two piece of second back up pad 23 interval vertical is located at described second leveling board 22 bottom surface, and the height of described reflecting plate 21 under described second leveling board 22 bottom surface is greater than the height of described two piece of second back up pad 23;
Described laser range finder 3 is located between the first leveling board 11 of described launcher 1 and side shield 12.
As shown in Figure 5, when crane girder span measures operation, launcher 1 is arranged at the upper flange 41 of a crane girder 4 through railing 43, to support whole launcher 1 on the platform 42 that two piece of first back up pad of launcher 1 is seated this crane girder 4 side, location-plate is against the lateral surface of this upper flange 41; Acceptance frame 2 is seated to support whole acceptance frame 2 on the platform 52 of another root crane girder 5 side through upper flange 51, two pieces of second back up pads that opposite side railing 53 is arranged at another root crane girder 5, and reflecting plate is against the lateral surface of this upper flange 51.Launcher 1 and acceptance frame 2 arrange appropriate after, adopt laser range finder 3 to measure distance to acceptance frame 2 reflecting plate, by calculating the measured value that can obtain crane girder span; Its computing formula is:
L=F-B+2t+D
In formula, L is the calculated value of crane girder span, and F is the distance of laser range finder front end to acceptance frame reflecting plate, and this numerical value can directly read on laser range finder, D is crane girder upper flange width, can carry out check by design drawing or in-site measurement to obtain, B is the distance of laser range finder front end to launcher location-plate lateral surface, and it is fixed value, can measure in advance and obtain, t is the thickness of slab of location-plate and reflecting plate, its fixed value, can measure in advance and obtain.
At the scene in actual measurement, this device can be set up in position, arbitrfary point on crane girder, thus record F value, namely by calculating the crane girder span value at this place, about 1 minute time is only needed owing to measuring a some position, therefore Quick Measurement when can select to drive a vehicle not operation herein, realize the on-line checkingi of crane girder span, realize when drive a vehicle do not stop transport, on-line implement measures the span of crane girder any point, and through scene repeatedly application obtain good result.
