Abstract
The invention relates to an overload device of a crane, in particular to a protection device for safely using the crane, belonging to the technical field of measurement control. The invention is characterized in that a bearing is mounted in a pulley; a shaft and a shaft sleeve are installed in a pulley support; a pallet shaft is used to fix the shaft on the pulley support by using a bolt; a shaft type sensor is fixed in the pulley support; the pallet shaft is used to fix the shaft type sensor on the pulley support by using the bolt; a lantern ring, a rope clip, a steel wire rope, a shackle and an ear plate are connected to be a whole; and the ear plate is fixed at a position requiring force measurement of the crane by using electrical wielding. The invention has the advantages that the structure is simple, compact and reliable; weighting and force measurement have high precision and good stability, and mechanical parts are greatly simplified, thereby reducing production cost and simplifying work amount of installation and debugging; the work is safe and reliable; and the device is convenient for assembling and dismantling, and can improve correct rate of count to ensure the safe use of the crane.
Description
Technical field
The present invention relates to a kind of overload device of hoisting crane, a kind of fender guard of crane safety use specifically belongs to the measure control technical field.
Background technology
At present, the various overload device of in hoisting crane production is used, using exists many problems, like 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
The objective of the invention is to overcome above-mentioned weak point, thereby provide a kind of safe and reliable, be convenient to assembling, dismounting can improve the counting accuracy, to guarantee the overload device of the hoisting crane that crane safety uses.
According to technical scheme provided by the invention; The overload device of hoisting crane 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 are fixed by bolts on the pulley support, with the axis plate shaft type sensor are fixed by bolts on the pulley support; The collar, rope clamp, steel rope, shackle and otic placode are connected as a single entity, and otic placode electricity consumption solid welding fixes on the required dynamometry of hoisting crane position.
Compared with present technology the present invention has the following advantages:
The present invention 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, following holder assembly pulley is through reaching dynamometry by the dynamometry steel rope; The dynamometry of weighing precision is high, good stability, and 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.
