Abstract
The utility model discloses a crown block shackle hook, which consists of a speed reduction motor, a cross connecting jaw, an insulation plate, a seized cap, a central nut, a bearing, a bearing seat and a hook. The output shaft of the speed reduction motor is inserted into the shaft sleeve of the cross connecting jaw, and the motor base is connected with the bearing seat through a bolt. Between the cross connecting jaw and the central nut is the insulated plate and the seized cap. The hook penetrates the bearing seat and is connected with the central nut. The utility model does not have the output shaft of the speed reduction motor directly connected with the insulation structure, which increase the arm of force and the contact surface during the torque transmission, efficiently reduces the squeezed stress of the insulation structure from the speed reduction motor to the hook, as well as expands the life span of the insulation structure.
Description
Technical field:
The utility model belongs to the shackle hook mechanism that a kind of electrolytic aluminium factory electrolytic bath goes out the aluminium special use.
Background technology:
The electrolysis overhead traveling crane shackle hook reducing motor output shaft that uses in the prior art all is directly to link to each other with insulation system at present, and the suffered squeese pressure of insulation system is very big, and shortened its service life greatly, can not satisfy the production needs.
Summary of the invention:
The purpose of this utility model is: provide a kind of shackle hook reducing motor output shaft to the brand new between the suspension hook, to improve insulation system service life, satisfy and produce needs.
The utility model is to constitute like this: it is made up of reducing motor (1), cross connection pawl (2), insolator disc (3), Ka Gai (4), center nut (5), bearing (6), bearing (7), bearing seat (8), suspension hook (9), motor cabinet (10), insulating part (11), and the output shaft of reducing motor (1) is connected with the trepanning that cross connects pawl (2); Be provided with insulating part (11) between reducing motor (1) and the motor cabinet (10), and bolt together; Motor cabinet (10) and bearing seat (8) bolt together; Be provided with insolator disc (3), Ka Gai (4) between cross connection pawl (2) and the center nut (5), and bolt together; Center nut (5) is placed in the bearing seat (8) by bearing (6), bearing (7); Suspension hook (9) passes bearing seat (8) and is connected with center nut (5).
Owing to adopted above scheme, make the utility model compare with existing shackle hook, the reducing motor output shaft no longer directly links to each other with insulation system, transfer torque on the insolator disc but connect pawl by cross, drive the suspension hook rotation by Ka Gai and center nut again, so just strengthened the arm of force and contact surface when moment of torsion transmits, it is stressed to the extruding of insulation system between the suspension hook to have reduced reducing motor effectively, the service life of having improved insulation system.In addition, use Ka Gai to cooperate the flat of thread of center nut to transmit torque on the suspension hook, this structure has also improved the reliability and the durability of suspension hook greatly.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
The specific embodiment:
Embodiment of the present utility model: the bearing seat (8) of successively thrust ball bearing (6), center nut (5) and copper bearing (7) being packed into earlier, again Antimagnetic lifting hook (9) is passed the hole of bearing seat (8) bottom and screws in center nut (5), load onto Ka Gai (4), nylon insolator disc (3) and cross then successively and connect pawl (2), and use the articulation hole bolt together; The lower end of motor cabinet (10) is connected with bearing seat (8) with bolt, and the upper end then uses bolt to be connected with cycloidal-pin wheel reducing motor (1) with insulating part (11); The output shaft of cycloidal-pin wheel reducing motor (1) penetrates in the trepanning of cross connection pawl (2), and connects with flat key.
