The two sides of heavy-duty machine hook offer multiple movable through-holes being connected to movable chamber, and the two sides of the crane hook are equipped with relatively
Vertical crash-proof bracket, the crash-proof bracket are C character form structure, offer multiple slidings corresponding with movable through-hole on crash-proof bracket
Hole is slidably fitted with horizontally disposed buffering stock in the sliding eye, and one end of the buffering stock is equipped with pushing block, and pushes away
Block is located at the mutually separate side of two crash-proof brackets, and spring is arranged on the buffering stock, and the spring is located at crane extension
Between hook and crash-proof bracket, the other end of the buffering stock is equipped with limit card block, and limit card block is located at the interior of movable chamber
Portion.
Preferably, the inside that movable through-hole extends to movable chamber, and buffering stock point are run through in one end of the buffering stock
Inner wall not with movable through-hole and sliding eye is slidably connected.
Preferably, the width of the movable through-hole and the width of sliding eye are respectively smaller than the diameter and limit card block of spring
Width.
Preferably, the bosom position of the movable chamber is welded with vertical stiffener rib, and the two sides of vertical stiffener rib are welded with
Multiple inclined stiffeners, and triangular structure is constituted between two neighboring inclined stiffener and vertical stiffener rib.
The beneficial effects of the utility model are: by designing mobilizable crash-proof bracket, benefit in the two sides that crane is linked up with
With crash-proof bracket under the action of elasticity, drives buffering stock interior flexibly flexible in crane hook, guarantee in normal use
Buffer stock elasticity effect under by crash-proof bracket to both sides eject, alleviate crane hook use when with crane shell or
The impact force that other objects occur reduces failure rate and cost, improves the use quality of crane, and the utility model design is closed
Reason, it is easy to operate, under the situation for guaranteeing crane normal work, hook and the extraneous impact force generated can be alleviated, reduced
Failure rate and cost improve the use quality of crane.
