Abstract
The utility model discloses a shaft pin type crane overload limiter which is characterized by comprising an overload limiter body used for serving as a pulley shaft, wherein one end of the overload limiter body is fixed with a crane main beam through an upper clamping plate and a lower clamping plate; the other end of the overload limiter body is fixed with the crane main beam through a cover plate. The shaft pin type crane overload limiter has the advantages that the overload limiter serves as the pulley shaft, so that the shaft pin type crane overload limiter according to the utility model is high in sensitivity and high in precision, and the manufacturing cost is also reduced; by adoption of a split structure, the shaft pin type crane overload limiter is simple in structure and easy and convenient to mount and maintain.
Description
Technical field
the utility model relates to a kind of load limiter, especially a kind of axial pin type overload crane killer.
Background technology
hoisting crane belongs to a kind of of elevator machinery, the machinery of a kind of circulation, intermittent moment, a working cycle comprises: load-engaging device is mentioned article from getting thing, then be moved horizontally to appointed place and fall article, then carry out counter motion, make load-engaging device reposition, to circulate next time.But when playing heavy articles, there is a lifting limit, if exceed the loss to weight-lifting equipment to greatest extent of lifting, there is very large threat with the safety of production operation, having at present quite a few weight-lifting equipment not have hoisting limiting apparatus, be all to weigh according to the load-bearing limit of equipment self, or lifting limit amount precision is not high, sensitivity is bad, not by lifting weight limits in a safe range, easy like this device damage and the safety misadventure of causing, is unfavorable for personal security; And prior art middle pulley group need be arranged on an axle, centre separates with spacer, and whole installation process all need to complete in the inner narrow space of girder, thereby causes installation and maintenance difficulty and time-consuming.
Summary of the invention
the utility model object is: provide a kind of simple in structure, installation and maintenance are easy, and the axial pin type overload crane killer that sensitivity is good, precision is high.
the technical solution of the utility model is: a kind of axial pin type overload crane killer, it is characterized in that, comprise for the load limiter body as sheave shaft, described load limiter body one end is fixed by upper and lower two clamps and crane girder, and the described load limiter body other end is fixed by cover plate and crane girder.
preferably, axle sleeve in the middle of described load limiter body is provided with, described middle axle sleeve two ends are provided with assembly pulley.
preferably, described load limiter body two ends are respectively equipped with end axle sleeve, described end axle sleeve with described in the middle of the axle sleeve dead sheave group that matches.
preferably, described load limiter body is provided with draw-in groove, and the position of described draw-in groove is corresponding with described clamp.
preferably, in described load limiter body one end, be provided with load limiter outlet.
preferably, described clamp and described cover plate are all fixing by bolt and crane girder outside.
the utility model installation steps are as follows, first the two ends of axle sleeve in the middle of assembly pulley being arranged on, and by the hole at crane girder top, assembly pulley and central axle sleeve are put into crane girder inside, then load limiter body penetrates central axle sleeve inside, the two ends of again end axle sleeve being inserted to load limiter body, load limiter body one end is fixed by upper and lower two clamps and crane girder, and the load limiter body other end is fixed by cover plate and crane girder.
the utility model has the advantages that:
1. the utility model serves as sheave shaft by load limiter simultaneously, makes that the utility model axial pin type overload crane killer sensitivity is good, precision is high, saves manufacturing cost simultaneously.
. the utility model adopts split-type structural, not only simple in structure, and installation and maintenance are easy.
