Bar bottom is stretched out from the bottom outlet of inside casing, and is fixedly connected with pulley yoke in downrod lower end, is rotated on pulley yoke and sets pulley, lifting
Hook, which is hung oneself, sets steel wire rope, and steel wire rope commutates via pulley, and guide holder is fixed with the suspension rod, and limit switch is installed on spring side
Portion surface, elevating lever is further fixed on limit switch, the body of rod lower end of elevating lever is stretched into the pilot hole of guide holder, mounting bracket
Bottom is further fixed on the limiting plate being engaged with limit switch.
As further improvement of the utility model, the inside casing by hex nut, hex bolts, plain cushion and spring washer with
Mounting bracket is fixedly connected.
As further improvement of the utility model, the body of rod of the suspension rod is provided with ring-type spacing preiection, and ring-type is spacing
Raised external diameter is more than the internal diameter of inside casing bottom outlet.
As further improvement of the utility model, the pulley yoke includes two pieces of baffle plates be arrangeding in parallel, two pieces of baffle plates
Top is connected by first axle with suspension rod, and pulley is installed in two pieces of baffle plates by the second axle and bearing.
It is of the present utility model to have technical effect that：At work, weight is hung on hook the utility model product, by
Hauling machine pulls hoisting wirerope, drives hook to carry out lifting the lifting operation that can be completed to weight, weight drives suspension rod
Descending, suspension rod pulling limit switch is descending, and when hoisting heavy overloads, limit switch lower end is resisted against on limiting plate, sends report
Alert signal, that is, realize alarm.
Brief description of the drawings
