Description
Technical field
The utility model belongs to hoisting machinery field more particularly to a kind of crane dropping-proof hook.
Background technology
Suspension hook is the important component on crane, and function is for hooking lifting rope.In the prior art, due to ordinary lifting hook
Do not have an anti-drop function, during handling weight, lifting rope may be slipped from suspension hook, cause security risk.Although on the market
When there are some suspension hooks with anti-drop function, but using this suspension hook, hangs up lifting rope and be inconvenient with the operation for removing lifting rope.
Invention content
The utility model provides a kind of crane dropping-proof hook, to solve the problems mentioned in the above background technology.
The technical issues of the utility model is solved is realized using following technical scheme：The utility model includes suspension hook sheet
The side of body, hook body is provided with sliding slot, and arc-shaped gear bar is equipped in sliding slot, and one end of arc-shaped gear bar is provided with the frustum of a cone,
The frustum of a cone is inserted into after being stretched out by the tip of hook body in the blind hole of hook body root, and the other end setting of arc-shaped gear bar is useful
In the handle that driving arc-shaped gear bar is slided in sliding slot, rotatable handle is mounted on the end face of arc-shaped gear bar, the outer edge of sliding slot
It is provided with the gap for accommodating handle, gap is referred to as gap A and gap B, rotating handle makes handle be in there are two being total to
In gap, arc-shaped gear bar can be made fixed in sliding slot.
The junction of the handle and arc-shaped gear bar be provided with make handle keep to gap bottom close to movement tendency
Torque spring.The root of the sliding slot is correspondingly arranged on strong magnet with the handle.
The beneficial effects of the utility model are：
1, the utility model is designed using novel anticreep, and when hanging up lifting rope or removing lifting rope, arc-shaped gear bar can return completely
It receives to sliding slot, lifting rope will not be counteracted so that picking and placeing for lifting rope is abnormal convenient.
2, arc-shaped gear bar is driven to slide using rotatable handle, when handle is located in gap A, arc-shaped gear bar end
The frustum of a cone be inserted in the blind hole of hook body root, prevent lifting rope from breaking off relations, when handle is located in gap B, arc-shaped gear bar end
The frustum of a cone in portion is received in hook body, avoids counteracting lifting rope, to considerably increase the convenience for picking and placeing lifting rope.
3, the junction of the handle and arc-shaped gear bar be provided with make handle keep to gap bottom close to movement become
The torque spring of gesture can effectively prevent handle to be skidded off out of gap, to further avoid the generation of decoupling accident.
4, the root of the sliding slot is correspondingly arranged on strong magnet with the handle, and arc-shaped gear bar is made to keep in the original location
Stablize.
