Description
Technical field
The invention belongs to crane field, and in particular to a kind of suspension hook, more particularly to a kind of crane Anti-slip lifting hook.
Background technology
Crane hook is the utensil for hoisting heavy, and when crane carries out slinging work, suspension hook is directly and weight
Contact, acted by the raising of crane and sling weight, while also need to ensure that the safety of weight is lifted by crane by suspension hook, so
And existing crane hook majority does not all have safe anti-slipping device, so during lifting, hoisting heavy mistake is easily caused
There is weight and mutually come off with suspension hook in weight center deviation when weight either lifts by crane, and causes inevasible security incident, while original
During beginning suspension hook slinging work can not accurate judgement suspension hook particular location and the distance apart from electric block, it is fixed to cause lifting
Position is inaccurate；Therefore it provides a kind of crane Anti-slip lifting hook reasonable in design, simple in construction, safe to use is very important.
The content of the invention
The invention aims to overcome the deficiencies in the prior art, and provide a kind of reasonable in design, simple in construction, use
The crane Anti-slip lifting hook of safety.
The object of the present invention is achieved like this：A kind of crane Anti-slip lifting hook, it includes hook body, described suspension hook
Body top is connected with rotating seat, and searchlight is provided with the downside of described rotating seat, report is provided with the right side of described hook body
Alert device C, described hook body centre position are provided with pin, and the junction of described hook body and pin is provided with torsion
Spring, described torsionspring downside are provided with electronic lock, and described electronic lock is connected with electromagnetic relay, and described hangs
The setting of hook body lower end is fluted, and gravity sensor A and gravity sensor B are provided with described groove, and described gravity passes
Spacing block is provided between sensor A and gravity sensor B, described groove left end is provided with alarm A, described groove right-hand member
Alarm B is provided with, described alarm A left ends are provided with pressure sensor.
Described electronic lock is to electrically connect with the connected mode of electromagnetic relay.
Described pressure sensor is to electrically connect with the connected mode of electromagnetic relay.
Described gravity sensor A is formed with alarm A and electrically connected.
Described gravity sensor B is formed with alarm B and electrically connected.
Described gravity sensor A and gravity sensor B electrically connects with alarm C.
The quantity of described searchlight is 2.
Described alarm A, alarm B and alarm C is audible-visual annunciator.
Beneficial effects of the present invention：The present invention is arranged on crane, when carrying out slinging work, will play weight
Rope both ends are suspended to gravity sensor A and gravity sensor B top in hook body groove respectively, then control crane to hang
Hook slowly rises until rope is exceptionally straight and drives the liftoff stopping of weight, and at this moment gravity sensor A and gravity sensor B can distinguish
Measure the weight at respective rope, when left end rope bear weight it is big when, then the alarm A being connected with gravity sensor A is sent
Sound and light alarm, at this moment can adjust the position of hoisting heavy center of gravity by reducing suspension hook, when right-hand member rope, to bear weight big
When, then the alarm B being connected with gravity sensor B sends sound and light alarm, then adjusts weight center of gravity by reducing suspension hook, until
Untill alarm does not occur for alarm A and alarm B, the gravity on the rope of both ends is measured as gravity sensor A and gravity sensor B
Exceed each set threshold value when, then can be determined that the hoisting heavy on crane hook is overweight, at the same with gravity sensor A
The alarm C connected with gravity sensor B sends sound and light alarm, notifies that weight is overweight by staff, avoids weight and lifted by crane
The contingency occurred in journey due to deviation of gravity center and overweight phenomenon；When weight in transportation is lifted by crane due to weight occur
Surprisingly wave when causing on suspension hook the rope to depart from groove, left end rope produces necessarily with regard to that can touch pressure sensor, and to it
Extruding force, the electromagnetic relay electrically connected with pressure sensor can just control electronic lock to unlock, and such pin is reversing
Outwards ejected in the presence of spring, the end of pin just clasps suspension hook outer end, in the presence of pin, can prevent lifting rope from taking off
Fall suspension hook, ensure that weight can land safely；Using searchlight, can be seen in lifting around suspension hook either with or without barrier
With apart from the position of electric block, during practical operation, two searchlights can be opened simultaneously, and staff can be beaten by light
In the position of wall, judge the general height that suspension hook rises, substantially increase operating efficiency；The present invention is reasonable in design, structure is simple
Singly, security performance is high during use, good antiskid effect, can avoid the generation of peril.
