2, level meter or transit survey method
Spirit-leveling instrument or transit are placed on leveling behind appropriate location, the straight steel ruler absolute altitude of measurement girder span centre gusset place, end carriage center, cantilever end carries out calculating camber value respectively.The camber value application condition that this method is measured is large, as dolly measures inaccurate generation error by its path wear deformation effect is comparatively large; Make the bad measurement when crane loading bulky items in this way, and erection instrument limits by space, place, ground and light.
Summary of the invention
The utility model object is the deficiency overcoming above several measuring method, the supporting measurement mechanism that provide a kind of for the electric single-beam of overhead and gantry cranes and the measurement of girder camber and be easy to operate, measuring accuracy is high, can complete measuring method on ground.
The supporting measurement mechanism technical scheme of overhead and gantry cranes tool camber measuring method described in the utility model is, this device forms primarily of laser range finder, spirit-leveling instrument, rule and tripod, described rule upper end is fixed on the shell of laser range finder side, lower end is fixed on described tripod head, and described spirit-leveling instrument is placed in together with its tripod and is can be observed in the measurement range of rule scale by spirit-leveling instrument eyepiece.
Described laser range finder adopts measuring accuracy to be 1mm laser range finder, and described spirit-leveling instrument adopts measuring accuracy to be ± 1mm spirit-leveling instrument.Rule can adopt 15mm Steel Ruler.Rule two ends make to be fixed by bolts on the shell of laser range finder side with on tripod head respectively.
Described tripod is provided with the adjustment king-rod of adjustment The Cloud Terrace height, regulates after being unclamped by king-rod locking knob.
The supporting measurement mechanism beneficial effect of this overhead and gantry cranes tool camber measuring method is:
Compared with other measurement mechanisms, the utility model simple operation, survey crew is without the need to assembling test equipment at the scene, and can measurement be completed on ground, erection instrument limits less by space, place, ground and light, finding range 1m to 50m, measuring accuracy reaches ± 1mm, measures and accurately, is conveniently suitable for; Supporting measurement mechanism structure simply, relatively cheap, be easy to carry, there is good popularizing application prospect.
