A kind of lower hook assembly of this utility model, including two symmetrical lower hook housing pieces；Two lower hook housing piece make-ups
After connection, upper end forms two orthogonal chain annular grooves, and lower end forms gib head trough；The chain annular groove and the gib head of longitudinal direction
Groove is communicated；Two lower hook housing pieces laterally offer the through hole being interconnected, the chain annular groove of the through hole connection longitudinal direction；
The inner peripheral surface waist of the gib head trough is provided with bearing groove, and the gib head trough is inserted into the gib head of lower suspension hook, the lower suspension hook
Axle sleeve is arranged with gib head, and the axle sleeve is located in the bearing groove, offers annular groove, institute on the gib head of the lower suspension hook
State and between axle sleeve and the groove, be provided with multiple steel balls.
Further, the through hole is shoulder hole, and greatly, the opening of inner side is little for the opening in outside.
Further, the cross sectional shape of the groove is semicircle.
Further, the section radius of the groove are equal with the section radius of the steel ball.
Further, multiple steel balls are closely arranged along the groove.
Further, the axle sleeve lower end has a bayonet socket, outside the inner peripheral surface of the bayonet socket and the gib head of the lower suspension hook
Side face gap coordinates.
Further, two lower hook housing pieces are stepped up by riveted.
Further, two lower hook housing pieces are bolted and step up.
Further, the gib head of the lower suspension hook with the axle sleeve through heat treatment.
Compared with prior art, Advantageous Effects of the present utility model are as follows：
This utility model is provided with two orthogonal chain annular grooves, a hoisting-chain chain foremost on lower hook housing piece top
Ring enters one of chain annular groove, and second chain link enters another chain annular groove, and two chain links are limited in by depth ground chain annular groove
In lower hook assembly, make hoisting-chain will not occur large angle pendulum foremost between lower hook assembly；And in lower suspension hook
Gib head periphery on open up groove, arrangement steel ball in groove, and be arranged axle sleeve on the outside of steel ball forms class bearing structure, will
Axle sleeve is stuck in the bearing groove between two lower hook housing pieces, allows lower hook assembly itself to rotate, and turns hoisting-chain
It is dynamic；Using safety, stabilized structure.
Description of the drawings
The utility model is described in further detail for explanation below in conjunction with the accompanying drawings.
Fig. 1 is lower hook assembly structural representation；
Fig. 2 is lower hook assembly top view；
Description of reference numerals：1st, lower hook housing piece；2nd, chain annular groove；3rd, gib head trough；4th, through hole；5th, bearing groove；6th, lower suspension hook；7、

Specific embodiment
As shown in Figure 1, 2, a kind of one of which specific embodiment of lower hook assembly, including two symmetrical lower hook housing pieces
1, two lower hook housing pieces are buckled togather, and are bolted, can also riveted in certain other embodiments.Two lower hooks
After the connection of 1 make-up of frame piece, upper end forms two orthogonal chain annular grooves 2, and lower end forms gib head trough 3, and gib head trough is cylindrical hole；
The chain annular groove 2 of longitudinal direction is communicated with the gib head trough 3, makes lower hook assembly longer with chain connecting length, and hoisting-chain is in chain
Arbitrarily will not rock in annular groove, hoisting-chain chain link foremost is penetrated in longitudinal chain annular groove, penultimate chain link enters horizontal
To chain annular groove in, fixation it is more stable.Two lower hook housing pieces 1 laterally offer the through hole 4 being interconnected, the through hole
The chain annular grooves 2 of 4 connection longitudinal directions, after the hoisting-chain is penetrated in chain annular groove, are penetrated in through hole with bearing pin, complete hoisting-chain with
The connection of lower hook assembly.The inner peripheral surface waist of the gib head trough 3 is provided with bearing groove 5, and the gib head trough 3 is inserted into lower suspension hook
6 gib head, is arranged with axle sleeve 7 on the gib head of the lower suspension hook 6, the axle sleeve 7 is located in the bearing groove 5, the lower suspension hook 6
Gib head on offer annular groove 8, the cross sectional shape of the groove 8 is semicircle, the section radius of the groove 8 with it is described
The section radius of steel ball 9 are equal, are provided with multiple steel balls 9 between the axle sleeve 7 and the groove 8.
More than, the gib head of the lower suspension hook 6 is with the axle sleeve 7 through heat treatment so as to reaches certain hardness, makes
Abrasion between gib head and steel ball is less.
Specifically, the through hole 4 is shoulder hole, and greatly, the opening of inner side is little for the opening in outside, with bearing pin through after through hole,
Bearing pin two ends are positioned with nut, and nut can be hidden in through hole, prevent damage of colliding with.
