Abstract
The utility model relates to a crane shaft coupling which comprises a female connector (1), a male connector (2) and a cushion block (3) and is characterized in that the cushion block (3) is embeddedbetween the female connector (1) and the male connector (2); a plurality of cylindrical petals (3.1) are uniformly distributed on the outer edge of the cushion block (3) to form a plum blossom circleshape corresponding to the cylindrical petals (3.1); and a lug I (1.1) and a lug II (2.1) meshed with the female connector (1) and the male connector (2) are respectively arranged in the correspondingpositions of the female connector (1) and the male connector (2). The plum blossom circle-shaped cushion block is meshed between the lugs of the female connector (1) and the male connector (2) and stably occluded and has long service life. Even if the plum blossom circle-shaped cushion block is broken, the lugs of the female connector (1) and the male connector (2) also can be mutually occluded,so that the phenomenon that objects directly beat people and other objects when falling down form upper air is avoided. The crane shaft coupling has the advantages of safe use, simple structure and good reliability.
Description
(1) technical field
The utility model relates to a kind of shaft coupling, relates in particular to a kind of hoist shaft coupling.Belong to the transmission connection piece technical field.
(2) background technique
Shaft coupling is a kind of connector that connects power shaft, driven shaft.Be widely used in being in transmission connection of engineering practice such as tower machine.It comprises the male and female joint substantially and is arranged on therebetween nylon rod.By the nylon rod that the grafting of male and female connecting head is assisted, comparatively soft transmitting torque.
Before the utility model was made, original shaft coupling (referring to Fig. 5～7) was made up of female connector 1, public connecting head 2 and nylon rod 4, is evenly equipped with slotted eye I 1.1 ', slotted eye II 2.1 ' on female connector 1, public connecting head 2 respectively.The slotted eye I that inserts on the male and female connecting head by nylon rod 4 is connected with slotted eye II, and the shortcoming of this kind shaft coupling is: the tower machine connects nylon rod and ruptures easily when running up, the replacing nylon rod is frequent, both consuming time, take material again, can incur loss through delay manufacturing schedule in the construction.If particularly when the handling object, rupture, security incident will take place, object falls from the high-altitude and directly hits people and thing, has great potential safety hazard.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of hoist shaft coupling of safe in utilization, simple in structure, good reliability is provided.
The purpose of this utility model is achieved in that a kind of hoist shaft coupling, it comprises female connector, public connecting head and cushion block, it is characterized in that described cushion block is embedded between female connector and the public connecting head, described cushion block outer rim is evenly equipped with several cylinders shape petal, constitute the plum blossom cast, corresponding to this cylindric petal, the corresponding position is respectively arranged with projection I and the projection II that is meshed with it on described female connector and the public connecting head.
The utility model hoist shaft coupling, the quantity of described cylindric petal are 8, and the quantity of described projection I and projection II respectively is 4.
The utility model hoist shaft coupling is engaged on plum blossom cast cushion block between the projection of female connector and public connecting head, and interlock is firm, plum blossom cast cushion block long service life.Even plum blossom cast cushion block ruptures, object can not take place and fall from the high-altitude and directly hit the phenomenon of people and thing in yet interlock mutually of the projection between female connector and the public connecting head.The utility model hoist shaft coupling, safe in utilization, simple in structure, good reliability.

(5) embodiment
Referring to Fig. 1～4, the utility model hoist shaft coupling is made up of female connector 1, public connecting head 2 and cushion block 3.Described cushion block 3 is embedded between female connector 1 and the public connecting head 2.Described cushion block 3 outer rims are evenly equipped with several cylinders shape petal 3.1, constitute the plum blossom cast, and corresponding to this cylindric petal 3.1, the corresponding position is respectively arranged with projection I 1.1 and the projection II 2.1 that is meshed with it on described female connector 1 and the public connecting head 2.
The quantity of described cylindric petal 3.1 is 8, and the quantity of described projection I 1.1 and projection II 2.1 respectively is 4.
Claims (2)
1, a kind of hoist shaft coupling, it comprises female connector (1), public connecting head (2) and cushion block (3), it is characterized in that described cushion block (3) is embedded between female connector (1) and the public connecting head (2), described cushion block (3) outer rim is evenly equipped with several cylinders shape petal (3.1), constitute the plum blossom cast, corresponding to this cylindric petal (3.1), described female connector (1) and public connecting head (2) are gone up the corresponding position and are respectively arranged with projection I (1.1) and the projection II (2.1) that is meshed with it.
