Description

A kind of Novel hook anti-drop device

Technical field

The utility model belongs to Casting Equipment technical field, and in particular to a kind of Novel hook anticreep of casting fusing crane Device.

Background technology

Currently, the melting process handling molten iron of foundry enterprise hoist lifting hook anti-drop device dismantle under high temperature environment it is tired Difficulty, the consuming time is long, and operation is dangerous, is unfavorable for frequent operation, complicated, inconvenient maintenance, efficiency is low, solution people Usual people pulls anticreep spring hanging plate, and then land crane, so that drop hanger is detached from the lifting lug of molten iron satchel, exists in disassembly process and hold The danger easily scalded by ladle, and expend the shortcomings of time is long, and efficiency is low, inconvenient for operation.

Invention content

The purpose of this utility model is to provide a kind of Novel hook anti-drop device, avoids crane high temperature disassembly process ladle The problem of breaking off relations, ladle scald occur, and change it is quick, it is flexible to operation, lifting is efficient.

The purpose of this utility model is realized using following technical scheme：

The assembly side inside of a kind of Novel hook anti-drop device, including suspension hook, detachable anti-drop device, the suspension hook opens up There is hanging hole, convex block magnet is installed on the outside of the assembly side of the suspension hook, the detachable anti-drop device includes that anticreep hooks plate, dead weight thick stick Lever arm, installing port, the anticreep hooks plate, dead weight lever arm is integrally formed by axle center of installing port；The detachable anti-drop device Installing port it is corresponding with the hanging hole on the inside of the suspension hook assembly side, detachable anti-drop device is fixed on by suspension hook by installing port On the inside of assembly side on hanging hole, the dead weight lever arm of the detachable anti-drop device is equipped with rotary strip close to one end of installing port Shape iron block, rotatable bar shaped iron block mutually inhale cooperation by the convex block magnet on the outside of windup-degree counterclockwise and the suspension hook assembly side Fixed, the detachable anti-drop device hooks plate and hangs by dead weight lever arm with anticreep is made under the common gravity of rotatable iron block Self-locking is closed at hook-bill.

Further, the shape of detachable anti-drop device is " 7 " font.

Further, the installing port of detachable anti-drop device is positioned with movable latch, and locking nut is used in combination to fix.

The Novel hook anti-drop device of the utility model, under normal condition, the dead weight lever arm of detachable anti-drop device with Anticreep is set to hook plate and be closed self-locking at suspension hook mouth under the rotatable common gravity of iron block, it, will be detachable when needing to lift satchel The rotatable bar shaped iron block windup-degree counterclockwise of dead weight lever arm on anti-drop device, until rotatable bar shaped iron block and convex block magnet It mutually inhales cooperation to fix, dead weight lever arm is lifted up, so that anticreep is hooked plate and is formed acute angle at suspension hook mouth, satchel is rapidly completed Afterwards, by detachable anti-drop device dead weight lever arm rotatable bar shaped iron block return, by dead weight lever arm with it is rotatable So that anticreep is hooked plate and is closed self-locking at suspension hook mouth under the common gravity of iron block, prevent satchel from breaking off relations, when removing satchel, will conduct oneself with dignity Dead weight lever arm is lifted up by the rotatable bar shaped iron block windup-degree counterclockwise of lever arm, to rotatable bar shaped iron block and Convex block magnet is mutually inhaled cooperation and is fixed, and so that anticreep is hooked plate and is formed acute angle at suspension hook mouth, isolates satchel, completes a circulation industrial Make.

The advantageous effect that the utility model obtains：

1. the dead weight lever arm of detachable anti-drop device passes through rotatable bar shaped in the lifting hook looseness preventing device of the utility model Iron block is mutually inhaled principle with convex block magnet and is fixed, and when crane operation, the rotatable bar shaped iron block conducted oneself with dignity on lever arm is turned round counterclockwise Gyration is fixed until rotatable bar shaped iron block mutually inhales cooperation with convex block magnet, and dead weight lever arm is lifted up, anticreep is made to hook plate Form acute angle at suspension hook mouth, satchel or when isolating satchel, not only flexible to operation and satchel process is used without artificial Long hook withstands dead weight lever arm, completes satchel and a cycle operation of unpacking only needs 3s, greatly promote crane lifting operation effect Rate, quality safety are reliable.

2. detachable anti-drop device is axle center using installing port in the lifting hook looseness preventing device of the utility model, with dead weight lever Arm, anticreep hook plate and are integrally formed, simple in structure, and are not necessarily to not damage the original suspension hook of crane, change faster convenience, at low cost.
