Description
Technical field
The present invention relates to a kind of suspension hook, particularly a kind of suspension hook with tripping gear.
Background technology
At present, in heat treatment industry, the lifting of workpiece is lifted using conventional structure suspension hook, weight and suspension hook
Disengaging needs operating personnel to remove suspension hook in tighter position, the hidden danger that high temperature personal injury be present；Meanwhile process is lifted by crane to workpiece
It is middle because of power-off suddenly or the driving emergency case such as failure, weight be present because inertia produces the danger of crooked unhook.Existing unhook
Device or the suspension hook with tripping gear, the country is mainly used in drop shutter test and the strong rammer operation in mine and building trade, though tool
Have simple in construction, safe and practical and there is automatically-unhooked advantage, come off, be not suitable for after being mainly used in a high position for weight because of it
Heat treated part needs the requirement that low level departs from suspension hook.For this reason, it may be necessary to it is improved.
The content of the invention
The purpose of the present invention is aiming at the deficiencies in the prior art, there is provided a kind of suspension hook with tripping gear, the suspension hook

Right balance, improves the flexibility of unhook, and increases the service life.
It is further preferred that control-rod includes two parallel clamping plates；The elongated insertion part is clamped two clamping plate front ends.With left and right
Symmetrical unhook control structure, it is ensured that lift hook unhooking control is flexibly, reliably.
Still more preferably, the lock hook is clamped in two clamping plate tail ends.To form firm structure, extend and use
Long lifespan.
Still further preferably, the first torsion spring is provided between the lock hook and clamping plate.Can to improve the locking of lock hook
By property, it is ensured that safe to use.
It is further preferred that the extension spring is provided with two, two extension springs are hung by a clamping plate with described respectively
Hook body connects.Reliability is improved, can be locked and the flexibility of unlocking motion.
Preferably, it is equipped with spring hangers on the hook body and control-rod；The extension spring is by hangers with hanging
Hook body connects with control-rod.Improve being convenient to mount and dismount property of extension spring and the reliability of connection.
Preferably, the movable hook is in asymmetrical v-shaped structure, and the outside edge lengths of movable hook are much larger than inner side edge；It is living
The hinged place of dynamic hook and hook body is located at immediately below the bottom land of V-shaped groove.Improve the reliability and agility of unlocking motion.
It is further preferred that the outer side edges free end end of the movable hook is formed with horizontal extension.To form abrasion
Deposit, increases the service life.
Preferably, the second torsion spring is provided between the movable hook and hook body.To facilitate mounting lifted weight thing, automatic shape
Into the complete suspension hook shape of force-free state, it is not required to external force and pulls movable hook, especially suitable for the contour, low temperature environment of hot and cold processing.
The invention has the advantages that suspension hook hoisting heavy is safe and reliable, remote control unhook can be carried out, is applied to
Hoisting heavy in high and low temperature environment.
