Abstract
The utility model discloses a crankshaft hanging lifting appliance for tempering, wherein a guide rail is arranged above a furnace chamber; the guide rail can be welded with a metal shell fixed above the furnace chamber into a whole and can also be fixed into a whole through bolts; the guide rail is matched with the guide wheel, a rotating shaft of the guide wheel is fixed on the upper supporting frame, a main pull rod is arranged in the middle of the upper supporting frame, and the position of the main pull rod corresponds to an upper channel of the furnace body; a connecting plate and a support plate are arranged below the main pull rod, and the connecting plate is arranged above the support plate; the upper part of the pull rod is fixed in the groove above the connecting plate, the lower part of the pull rod is connected with a hanging beam, a hanging frame is arranged on the hanging beam, and the lower part of the hanging frame is connected with the tray; the journal part of the crankshaft is clamped above the tray. The utility model has the advantages that: through the cooperation of the guide rail above the furnace body and the guide wheel, the swinging of the sling is avoided, and the defect of the collision between the crankshaft and the furnace body is overcome. The lifting appliance structure is provided with a plurality of groups of rotatable structures, so that the buffer can be guaranteed even if collision occurs, and rigid collision is avoided.
Description
Technical Field
The utility model relates to a bent axle manufacturing technical field specifically is a bent axle hoist.
Background
When the crankshaft is quenched and tempered in a suspension type heating furnace after being processed, a lifting appliance adopted in the prior art is fixed, a large-head flange of the crankshaft is clamped through a U-shaped lifting basket, the crankshaft is fixed in the lifting appliance, the crankshaft enters the suspension furnace along with a combined lifting appliance, and the processes of heating and quenching after heating are carried out. The weight of the crankshaft hoisted by the method is very large, such as several tons; the hoist cable of overhead traveling crane drives the crankshaft and is inevitable when directly passing through the heating furnace and rocks, should rock and cause the collision of crankshaft and furnace body very easily, then destroy the exterior shape of crankshaft lightly, then hit the bad with the furnace body inside heavily.
Disclosure of Invention
In order to solve the technical problems, the utility model aims to provide a crankshaft suspension lifting appliance for tempering, wherein a guide rail is arranged above a furnace chamber and is matched with the guide wheel, a rotating shaft of the guide wheel is fixed on an upper supporting frame, a main pull rod is arranged in the middle of the upper supporting frame, a connecting plate and a supporting plate are arranged below the main pull rod, and the connecting plate is arranged above the supporting plate; the upper part of the pull rod is fixed in the groove above the connecting plate, and the lower part of the pull rod is fixed with the tray; the journal part of the crankshaft is clamped above the tray.
The main pull rod is of a two-section structure, the upper section is provided with a groove portion, the lower section is provided with a protruding portion, the protruding portion is matched with the groove portion, and the connecting shaft is inserted into the protruding portion and the groove portion to connect the upper end and the lower section into a whole.
And the thread section above the main pull rod is fixed above the upper support frame through a gasket and a nut.
The utility model has the advantages that: through the cooperation of the guide rail above the furnace body and the guide wheel, the swinging of the sling is avoided, and the defect of the collision between the crankshaft and the furnace body is overcome. The lifting appliance structure is provided with a plurality of groups of rotatable structures, so that the buffer can be guaranteed even if collision occurs, and rigid collision is avoided.
