Description
Technical field
The utility model is related to suspension hook technical fields, in particular to a kind of anti-dropout suspension hook.
Background technology
Suspension hook is the most common type suspender in hoisting machinery.Since the workplace danger coefficient of suspension hook is higher, if
In the poor environment more than safety margins or sanitary standard, for example, dusty, high temperature, high humidity, low temperature, strong noise, strong wind day,
It is engaged in hoisting operation under underlit equal environment, will be taken sb's mind off sth, directly affects the respond of operating personnel, technology plays
Stability, make maloperation, the chance operated against regulations increases, it is most likely that object on suspension hook occurs and falls off, so as to cause accident
Generation, and under larger pressure effect, since steel wire rope is woven by steel wire strand, meeting under outer force effect herein
Rotational case is generated, the weight being lifted also rotates with suspension hook, at this moment cannot continue to sling or put down to have sling
Weight, the possibility that object on suspension hook falls off has been significantly greatly increased.Suspension hook rotation can influence being normally carried out for lifting operation, seriously
Threaten the safety of operating personnel and equipment, it is therefore necessary to avoid its generation.
Therefore it needs a kind of lifting object not easily to fall off at present, and the suspension hook of suspension hook rotation will not occur.
Invention content
To solve the above-mentioned problems, it provides that a kind of lifting object is not easily to fall off, and the suspension hook of suspension hook rotation will not occur, this
Utility model uses following technical scheme：
A kind of anti-dropout suspension hook, including suspension hook coupler body, anti-rotation device, anti-drop device：The anti-rotation device includes rotation
Portion and fixed part, the rotating part bottom are equipped with fixing groove, and the cross-sectional area of the fixing groove opening is less than fixing groove
Interior cross-sectional area, the fixed part include at the top of fixed part and interconnecting piece, in the fixation at the top of the fixed part
In slot, and it can horizontally rotate in the fixing groove, the cross-sectional area at the top of the fixed part is more than the fixation
Cross-sectional area at channel opening, and less than the cross-sectional area in the fixing groove, the top of the interconnecting piece and suspension hook coupler body
Portion connects, and the anti-drop device is connected between the top of suspension hook coupler body and hook tooth, and the anti-drop device includes baffle,
The baffle is hinged with suspension hook coupler body.
The effect that the utility model passes through anti-drop device so that the feelings that the steel wire rope of suspension hook rotates under external force
When condition, steel wire rope drives rotating part to rotate, and remains stationary at the top of the fixed part in rotating part fixing groove, to ensure suspension hook
Coupler body will not rotate situation with the rotation of steel wire rope.The internal stress of steel wire rope generated due to pulling force had both been eliminated in this way
Effect, prevent the damage of steel wire rope, and avoid the rotation of suspension hook, improve the safety of work.And this practicality is new
Type is provided with anti-drop device between the top of suspension hook coupler body and hook tooth, prevents the object in suspension hook from sliding with baffle, into one
Step improves the safety of lifting operation.
Preferably, being equipped with ball on the inside of the fixing groove.
The utility model is equipped with ball in the inside of fixing groove, and it is described in rotating part to reduce fixed part by ball
The resistance being subject to improves the rotational efficienty of rotating part, further reduces the possibility of suspension hook rotation, and extends anti-
The service life of de- device, reduces operating risk.
Preferably, the baffle is equipped with spring.
Preferably, the spring is compression spring.
The utility model uses the technical solution of spring, especially compression spring, can be pressed in baffle on hook tooth, hang in this way
Object slippage can be effectively prevent to cause danger when playing object.
The beneficial effects of the utility model are：（1）The case where can preventing suspension hook rotation, improve job safety
Property, it averts risks（2）It is not easily to fall off to lift by crane object, reduces accident probability.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of anti-rotation device.
Specific implementation mode
With reference to the accompanying drawings of the specification, the utility model is further described：
As shown in Figure 1, a kind of anti-dropout suspension hook, including suspension hook coupler body 1, anti-rotation device 2, anti-drop device 3, the anti-rotation
Device 2 includes rotating part 21 and fixed part 22, and 21 bottom of rotating part is equipped with fixing groove 211, and the fixing groove 211 is opened
Cross-sectional area at mouthful is less than the cross-sectional area in fixing groove 211, as shown in Fig. 2, the fixed part 22 includes fixed part top
Portion 221 and interconnecting piece 222,221 in the fixing groove 211 at the top of the fixed part, and can be in the fixing groove
Horizontally rotate in 211,221 cross-sectional area is more than the cross section of 211 opening of fixing groove at the top of the fixed part
Product, and it is equipped with ball 4, the connection less than the cross-sectional area in the fixing groove 211, and in 211 inside of fixing groove
Portion 222 is connect with the top of suspension hook coupler body 1, and the anti-drop device 3 is connected between the top of suspension hook coupler body 1 and hook tooth, institute
The anti-drop device 3 stated includes baffle 31, and the baffle 31 is hinged with suspension hook coupler body 1, and the baffle 31 is equipped with spring
32, the spring 32 is compression spring.
The object that will be lifted in use is sling after being fixed on suspension hook, passes through the effect of anti-drop device 3 at this time so that
When the case where steel wire rope of suspension hook rotates under external force, steel wire rope drives rotating part 21 to rotate, and in rotating part 21
221 remains stationaries at the top of fixed part in fixing groove 211, to ensure that the coupler body of suspension hook will not be revolved with the rotation of steel wire rope
Turn situation.The effect for both having eliminated the internal stress of steel wire rope generated due to pulling force in this way, prevents the damage of steel wire rope, and keeps away
The rotation for having exempted from suspension hook improves the safety of work.And the utility model is set between the top of suspension hook coupler body 1 and hook tooth
Anti-drop device 3 has been set, has prevented the object in suspension hook from sliding with baffle 31, has further improved the safety of lifting operation, and
And baffle 31 can be pressed on hook tooth using compression spring, object can be effectively prevent to slip when slinging object in this way, kept away
Exempt to cause danger.
