The utility model provides a kind of anti-rope tripping gear of lifting equipment suspension hook, which includes anticreep hook mechanism and shaft, and anticreep hook mechanism is connect by shaft with suspension hook；Anticreep hook mechanism is made of position-limited rack and gag lever post, and position-limited rack is integrally L-shaped, including positive stop end and Balance weight end, the length of Balance weight end is greater than the length of positive stop end, positive stop end and Balance weight end fix a gag lever post respectively, and the corner of L-type position-limited rack is machined with through-hole, can match with suspension hook upper shaft hingedly；The utility model structure is simple, is easy production, low in cost, easy to operate, securely and reliably, easy access, the design of anticreep hook mechanism design more ingenious compared to spring Anti-hook releasing device currently on the market, limit effect is more preferable, and is hardly damaged, and service life can greatly prolong.

Description

A kind of anti-rope tripping gear of lifting equipment suspension hook

Technical field

The utility model belongs to lifting equipment field, is related to the suspension hook of lifting equipment, specifically a kind of lifting equipment The anti-rope tripping gear of suspension hook.

Background technique

Suspension hook is one of suspender most commonly seen in lifting equipment, is suspended on lifting equipment by elements such as pulley blocks and rises On the wirerope for rising mechanism；The object for needing to lift is hung on suspension hook after wirerope bundlees, it can carries out lifting work； Commonplace suspension hook used at present is goat's horn suspension hook, and rope occurs in hoisting process in order to prevent and falls off and leads to work people The safety of member goes wrong, and rotatable tongue piece is equipped on suspension hook, and tongue piece abuts its end and hung by spring retainer Hook.When needing using suspension hook, the rope for needing to lift directly generally is hit into tongue piece, rope just can smoothly slide into suspension hook It is interior, but due to the long-term shock by rope, tongue piece can deform afterwards for a period of time in normal use, so that tongue piece end is not It can be bonded suspension hook completely, can thus make the function reduction for preventing from falling off, increase the security risk of suspension hook, while the components such as spring Limit, when unloading rope also due to the elastic force of the tongue piece spring of jumbo hooks is larger, make unload rope when it is time-consuming and laborious, The labor intensity for increasing operator reduces working efficiency, but also can have the risk for crushing operator.

Utility model content

The purpose of this utility model is just to provide one kind, and to have a structure simple, is easy production, low in cost, easy to operate, Securely and reliably, the anti-rope tripping gear of the suspension hook of the advantages that easy access, long service life.

Used technical solution is the utility model to achieve the goals above:

A kind of anti-rope tripping gear of lifting equipment suspension hook, including shaft and anticreep hook mechanism, the shaft are connected in The top at suspension hook opening position, anticreep hook mechanism are connect by shaft with suspension hook；Anticreep hook mechanism is by position-limited rack and gag lever post group At position-limited rack is integrally L-shaped, including positive stop end and Balance weight end, and the length of Balance weight end is greater than the length of positive stop end, the positive stop end Fix a gag lever post respectively with Balance weight end, the corner of L-type position-limited rack is machined with through-hole, matches hingedly with the shaft.

The anticreep hook mechanism is made of two position-limited racks and two gag lever posts, and two position-limited racks are arranged in parallel, both ends point It is not connected and fixed by a gag lever post.

The beneficial effects of the utility model are: the present apparatus can prevent rope de- from the opening position of suspension hook in process of production Out, the generation of safety accident is avoided；The present apparatus has structure simple, is easy production, low in cost, easy to operate, securely and reliably, The advantages that easy access, long service life；Spring Anti-hook releasing device currently on the market is compared in the design of anticreep hook mechanism, if Meter is more ingenious, and limit effect is more preferable, and operation is easier, and since mechanical structure is simple, realizes that mousing-hook designs using gravity, It is hardly damaged, the service life of the utility model can be made to greatly prolong, and can guarantee the personal safety of operator.

Specific embodiment

The utility model is described further with reference to the accompanying drawing:

A kind of anti-rope tripping gear of lifting equipment suspension hook turns as shown in Figure 1, including shaft 3 and anticreep hook mechanism 2 Axis 2 is connected in the top at the opening of suspension hook 1 position, and anticreep hook mechanism 2 is connect by shaft 3 with suspension hook 1；Anticreep hook mechanism 2 such as Fig. 3 It is shown, it is made of two position-limited racks 4 and two gag lever posts 5, position-limited rack 4 is whole L-shaped, including positive stop end 6 and Balance weight end 7, matches The length held again is greater than the length of positive stop end, and the size of size and suspension hook is adapted, and two position-limited racks 4 are arranged in parallel, both ends point Not Tong Guo a gag lever post 5 be connected and fixed, the mode being connected and fixed can be using being screwed connection, the turning of L-type position-limited rack 4 Place is machined with through-hole 8, can be threaded with 1 upper shaft of suspension hook, 3 coordination hinge, 3 top of shaft at both ends, install position-limited rack After 4, then it is connected and fixed by nut.

Under normal conditions, the state of the anti-rope tripping gear of lifting equipment suspension hook is as shown in Figure 1, anticreep hook mechanism 2 The positive stop end 6 of position-limited rack 4 has sealed the opening of suspension hook, while the gag lever post 5 of Balance weight end 7 is contacted with suspension hook 1, it is ensured that positive stop end 6 keep the closure of openings to suspension hook 1, when needing the rope by hanging object to be suspended on suspension hook 1, it is only necessary to overcome rope and match The gravity indentation positive stop end 6 at end 7 pulls Balance weight end 7 when needing to unload in rope upwards again, as shown in Fig. 2, limit End 6 can be that center of circle rotation is opened with shaft 3, can unload the rope being limited, while the gag lever post 5 of positive stop end 6, prevent from limiting The rotation angle at end 6 is spent greatly.

By installing the present apparatus additional on the suspension hook of lifting equipment, under the action of gravity and lever principle, the present apparatus can be with Play the role of preventing rope from falling off from the opening position of suspension hook in suspension hook use process, effectively avoids the hair of safety accident It is raw；The present apparatus can be used for gantry crane, truck crane, in a variety of lifting equipments such as tower crane, there is positive extensive promotional value.
