Abstract
The utility model relates to an overload device for a crane, in particular to a protective device safely used for a crane, which belongs to the technical field of measurement control. The protective device is characterized in that a bearing is installed in a pulley, a shaft and a shaft sleeve are installed in a pulley bracket, the shaft is fixed on the pulley bracket through a bolt and via a pallet shaft, a shaft sensor is installed in the pulley bracket and fixed on the pulley bracket through a bolt and via a pallet shaft, and a steel wire ringer structure is fixed in the position required for force measuring for the crane by electric welding. The utility model has the advantages that the protective device is simple and compact in structure, reasonable, high in weighing and measuring accuracy and good in stability, greatly simplifies the mechanical part, reduces the production and manufacturing cost, alleviates the work load of installation and debugging, has secure and reliable operation and convenient assembly and disassembly, improves the accurate rate of counting, and further ensures the operating safety of the crane.
Description
Technical field
The utility model relates to a kind of hoisting crane, a kind of fender guard of crane safety use specifically.
Background technology
At present, the various overload device of using in hoisting crane production is used exists many problems, as complex structure, installs, dismantles difficulty, and the counting accuracy is low, has buried safety in production hidden danger to hoisting crane virtually.
Summary of the invention
It is a kind of safe and reliable that the purpose of this utility model is to provide, and is convenient to assembling, and dismounting can improve the counting accuracy, to guarantee the overload device of the hoisting crane that crane safety uses.
The overload device of hoisting crane described in the utility model comprises pulley, axle, axle sleeve, clamp axle, pulley support, lining, axis plate, bearing, shaft type sensor, the collar, rope clamp, steel rope, shackle and otic placode, bearing installation is in pulley, axle, axle sleeve are installed in the pulley support, with the clamp axle axle is fixed by bolts on the pulley support, with the axis plate shaft type sensor is fixed by bolts on the pulley support, steelwire sleeve structure electricity consumption solid welding is fixed on the required dynamometry of hoisting crane position.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; During use, be suspended on the tested steel cable, top is fixed on the hoisting crane body with steel rope, shackle, the rope clamp collar, and at last pressure pulley, the subiculum assembly pulley is by reaching dynamometry by the dynamometry steel rope; The dynamometry of weighing precision height, good stability, mechanical part is simplified greatly, has reduced manufacturing cost, has simplified the Installation and Debugging work capacity; Safe and reliable, be convenient to assembling, dismounting can improve the counting accuracy, uses to guarantee crane safety.
