Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-7, a kind of tower crane suspension hook Anti-hook releasing device, including hanger bulk 1, hanger bulk 1 are equipped with suspension hook ear
Hole 5, hanger bulk 1 are equipped with handle 10, and the both sides of 10 one end of handle have been fixedly connected with side plate 2, have been equipped between two side plates 2
Mouth of hook closure member 6, mouth of hook closure member 6 include sealing plate 61, and the both sides of sealing plate 61 have been fixedly connected with baffle 62 so that it is convenient to rope
Suo Jinhang is limited, and mouth of hook closure member 6 is connect by locating piece 7 with side plate 2, and locating piece 7 includes two fixed plates 71, fixed plate 71
On be fixedly connected with positioning sleeve corresponding with suspension hook earhole 5 72, two positioning sleeves 72 are bolted by third, fixed plate 71 with
Connecting plate 3 is fixedly connected, and fixed plate 71 is connect by multiple first bolts with side plate 2, and fixed plate passes through the second bolt and baffle
62 connections, make mouth of hook closure member 6 be connect with side plate 2 and suspension hook earhole 5 by the effect of locating piece 7 in this way, and then facilitate it steady
Fixed rotation and limit, hanger bulk 1 are located between two side plates 2, and the one end of side plate 2 far from handle 10 is connected by connecting plate 3
It connects, mouth of hook closing protector is fixed on connecting plate 3, mouth of hook closing protector includes two folders being fixed on connecting plate 3
Plate 4, clamping plate 4 is connect by the 4th bolt with connecting plate 3 close to one end of connecting plate 3 so that it is convenient to which clamping plate 4 is solid with connecting plate 3
Surely connection hanger bulk 1 is located between two clamping plates 4, and clamping plate 4 is made of band steel, closes the effect of protector by the mouth of hook in this way
Playing prevents mouth of hook closure member 6 from rotating, and then is effectively limited to rope, and magnet 9 is equipped in clamping plate 4, makes folder in this way
What plate 4 was connect with hanger bulk 1 more stablizes, and connecting plate 3 is connect by tension spring 8 with hanger bulk 1.
In the utility model, suspension hook Anti-hook releasing device is articulated on suspension hook earhole 5, uses the mating height with self-locking nut
Strength bolt, or riveted using rivet, ensure the reliability being coupled.When rigging enters hook, rigging depress mouth of hook closure member 6 into
Enter in suspension hook, then tension spring 8 is under rebound effect so that mouth of hook closure member 6 is restored to mouth of hook closed state；Meanwhile the mouth of hook
Closing protector is softened after being pushed to by handle 10 and is stuck on hook neck, using the elastic clamping of steel plate, if being filled on clamping plate 4
If magnet 9 is then fixed using 9 suction of magnet, play the role of double protection；Both modes can realize suspension hook mousing-hook
Device makes the mouth of hook close, and can guarantee that mouth of hook closure member 6 has enough pressing forces；When the operation of tower crane operating mode is preferable, mouth of hook envelope
Closing protector and tension spring 8 can optional one.When rigging goes out hook, operation handle 10 makes Anti-hook releasing device rotate clockwise, and opens the mouth of hook
Closure member 6, opening degree size can be adjusted by handle 10, in order to take out rigging.It is existing that the utility model considers construction
Situation when field tower crane operating condition is poor, such as suspension hook occur and swing, shake, touch or occur suspension hook overturning situation, at this moment
Locating piece 7 can limit Anti-hook releasing device left and right displacement；6 both sides of mouth of hook closure member select round steel effectively to evade steel wire rope contact
There are corner angle on surface, and the sealing plate 61 between round steel opens up groove and consistent with 1 surface cambered surface of hanger bulk so that sealing plate 61 and hook
1 working face of ontology comes into full contact with face；The mouth of hook, which closes protector and tension spring 8, ensures that mouth of hook closure member 6 is in closed state always.
Before making the device, design has been carried out in the selection of material specification and has been calculated, it is ensured that tower crane suspension hook Anti-hook releasing device intensity reaches
Requirement.Therefore, tower crane suspension hook Anti-hook releasing device of the present utility model is safe and reliable.
The preferable specific implementation mode of the above, only the utility model, but the scope of protection of the utility model is not
Be confined to this, any one skilled in the art within the technical scope disclosed by the utility model, according to this practicality
Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
