The construction speed of engineering, so it is extremely important to produce safest crane grabhook.
The grabhook of the derrick crane of the prior art has the following problems：The grabhook of derrick crane is in some pipes of hook
When shape object or strip article, since, only there are one stress point, stress is extremely unstable on hook, during hook, these
Tube or strip article can cause entire article to be turned on one's side, from high-altitude since crank easily shifts when serious
In fall, staff on ground is caused greatly to injure, severe patient can cause casualties.
Utility model content
The purpose of this utility model is to provide a kind of security grabhook of derrick crane, to solve above-mentioned background skill
The inadequate safety problem of grabhook of the derrick crane proposed in art.
To achieve the above object, the utility model provides following technical solution：A kind of security lifting of derrick crane
Hook including grabhook body and prypole, is provided with clump weight above the grabhook body, the both sides of the clump weight are set
Be equipped with symmetrical prypole, and coiling tube stent be provided with above clump weight, be provided on the coiling tube stent around
Spool, the reel are connected by crane rope with derrick crane crossbeam, and prypole rope is provided on the prypole
Rope.
Preferably, the reel is rotatablely connected with coiling tube stent by reel shaft, and the crane rope can
Winding is on a bobbin.
Preferably, the one side of the grabhook body is provided with grabhook baffle, and grabhook body and grabhook baffle
It is rotatablely connected by grabhook shaft.
Preferably, rope fixed block is provided on the prypole rope, the rope fixed block can fix prypole rope
Rope does not slide on prypole.
Preferably, the prypole connects tubulose weight by prypole rope.
Preferably, the grabhook connects block weight by grabhook rope.
Preferably, the prypole is to be threadedly coupled with the mounting means of clump weight.
Compared with prior art, the beneficial effects of the utility model are：
The utility model installs symmetrical prypole in the both sides of the clump weight of crane grabhook, when crane grabhook
In those tubulose weights of hook block or dangerous bar shaped weight, article can be bundled simultaneously by two ropes on prypole
It slings.The incident safety problem of suspension hook is prevented by such mode, has ensured the safety of surface personnel.
