Description of reference numerals: 1. a hoisting sprocket; 2. an upper hook; 3. a first connecting member; 4. turnbuckle screws; 5. positioning a plate; 6. a second connecting member; 7. a lower hook connector; 8. a chain is hung; 9. a spring.
Detailed Description
As shown in fig. 1, a ring chain hoist comprises a hoisting sprocket 1, a first connecting piece 3, a turnbuckle 4, a positioning plate 5, a second connecting piece 6, a lower hook connecting piece 7, a lifting chain 8 and a spring 9, wherein the hoisting sprocket 1 is mounted on a motor and driven by the motor, an external power plug is arranged on the motor, and an upper hook 2 is connected to a hanger of a frame body; the first connecting piece 3, the spring 9, the turnbuckle 4, the positioning plate 5 and the second connecting piece 6 are sequentially arranged from top to bottom and are sequentially connected together; lifting hook 2 is connected with to the top of hoisting sprocket 1, lower lifting hook connecting piece 7 is located the bottommost, the bottom of lower lifting hook connecting piece 7 is connected with the lower lifting hook that is used for drawing the heavy object, the one end fixed connection of chain sling 8 is in the bottom of hoisting sprocket 1, the other end of chain sling 8 is walked around in proper order transition key on the first connecting piece 3 hoisting sprocket 1 transition key on the lower lifting hook connecting piece 7 fixed connection is in behind the transition key on the second connecting piece 6 the top of lower lifting hook connecting piece 7. Particularly, the adjustment of the connection tightness of the upper part and the lower part can be realized by adjusting the lengths of the fixing parts at the two ends of the turnbuckle 4, and the spring 9 is arranged between the first connecting piece 3 and the turnbuckle 4 and used for elastically adjusting the tightness of the hanging chain 8 and preventing the occurrence of chain jumping or dislocation.
And after the hanging chains 8 are connected, the top and the bottom of the hanging chains form a parallel three-row hanging chain structure. Compared with the four-row sling chain structure in the prior art, the four-row sling chain structure is more convenient and faster to connect, and the manufacturing cost can be greatly reduced after the whole length is shortened. The first connecting piece 3, the second connecting piece 6 and the transition keys on the lower hook connecting piece 7 are connected through bolt assemblies, and the transition keys specifically adopt four-tooth splines or five-tooth splines. The lower hook connecting piece 7 is simpler in structure and more convenient to install.
