Description

A kind of Anti-hook releasing device for the injury of crane gear suspension hook resistance to deformation

Technical field

Lifting equipment is the utility model is related to, is used for crane gear suspension hook resistance to deformation more specifically to one kind The Anti-hook releasing device of injury.

Background technology

Bridge crane (driving) is the conventional professional crane gear of the industry such as machining manufacture, transport, storage, simultaneously Crane gear belongs to the special equipment of national regulation, has enforceable working service specification, hoisting machinery Anti-hook releasing device is just It is one of safety device that state compulsion promotes in recent years.Driving Anti-hook releasing device, at suspension hook axle journal, purpose is exactly anti- Only the Current Collector Sleave such as steel wire rope, suspender belt escaped from suspension hook, come off caused by lifting injury accident.Manufactured after 2010 The suspension hook of crane gear carried out structure improvement, bulge-structure is provided with axle journal, is machined with through hole, by through hole Insert the function that alignment pin realizes installation Anti-hook releasing device.But in the crane gear used for, it is impossible to All updated within useful life, change suspension hook, cost is too high, therefore dissection type semi-ring knot can only be used on existing suspension hook Anti-hook releasing device, is fixed on the axle journal of suspension hook by structure (anchor ear form) by bolt.

Anti-hook releasing device is by element groups such as locating ring (anchor ear), screw, gland, springs used in current traditional suspension hook Into, be fixed on suspension hook axle journal position by locating ring (anchor ear) and screw, spring has 2 both sides for being separately mounted to gland, lead to Suspension hook inner ring is formed closed state by the effect of overpressure cap and spring, realizes the function of preventing that Current Collector Sleave is escaped in suspension hook.It is existing When field uses Anti-hook releasing device, operating personnel first breaks the gland of Anti-hook releasing device into two with one's hands upwards, and the suspension hook that script is closed forms U Type open state, then the Current Collector Sleaves such as steel wire rope, suspender belt are placed in suspension hook, unclamp gland, under the action of the spring gland from It is dynamic to reset, re-form the suspension hook state of closing.When taking out Current Collector Sleave, the gland of Anti-hook releasing device is first broken into two with one's hands, script is closed Suspension hook form U-shaped opening state again, then the Current Collector Sleaves such as steel wire rope, suspender belt are taken out from suspension hook, unclamp gland, in bullet Gland automatically resets in the presence of spring, re-forms the suspension hook state of closing.

The characteristics of due to hoisting operation is exactly that workload is big, rise to the bait, unhook operation is frequent, by Current Collector Sleave from suspension hook , it is necessary to which operating personnel's (play heavy industry, refer to and hang work etc.) first breaks the gland of Anti-hook releasing device into two with one's hands during taking off, then Current Collector Sleave is taken Go out, finger directly contacts with Current Collector Sleave in this course, is blocked there is the finger for breaking Anti-hook releasing device into two with one's hands by steel wire rope Potential safety hazard, and once break the finger slippage of gland into two with one's hands, gland, which automatically resets, to be damaged to the hand for taking out Current Collector Sleave. The stage clip structure that spring positioned at gland both sides uses, both ends of the spring stretch out, and easily stab the finger of operating personnel, exist certain Mechanical wounding hidden danger.

In summary, dissection type Anti-hook releasing device used in hoisting machinery lift hook traditional at present, it is operable at the scene Property aspect certain deficiency be present, be unfavorable for frequent operation, and certain potential safety hazard be present.
