Description

Locking device for crane hook

Technical Field

The utility model belongs to the technical field of lift by crane the apparatus, concretely relates to driving lifting hook fastener.

Background

The lifting hook is a common hoisting tool, and the figure of the lifting hook can be seen on tools such as cranes, travelling cranes and the like. The hook mouth of the lifting hook needs to be closed after articles are hooked, and accidental falling is prevented. The common structure among the prior art sets up the baffle in hook mouth department, and baffle department is equipped with torsion spring, utilizes the spring to make the baffle support the lifting hook, and then closed hook mouth prevents that the accident from droing. However, in the actual use process, the torsion spring is often easily damaged, so that the baffle cannot abut against the lifting hook, the hook opening cannot be closed, and the due effect of the baffle is lost.

SUMMERY OF THE UTILITY MODEL

To the technical problem, the utility model provides a driving lifting hook fastener, this fastener utilizes gravity to realize the closure to the hook mouth, simplifies the structure, improves life.

In order to solve the technical problem, the utility model discloses a technical scheme be:

a traveling crane lifting hook fastener comprises a lifting hook main body and a stop lever, wherein the stop lever is hinged with the lifting hook main body, one end of the stop lever is abutted against the lifting hook main body under the action of gravity, and a hook opening of the lifting hook main body is closed; the other end of the stop lever is provided with an adjusting block, the adjusting block is connected with the stop lever in a sliding mode, a jackscrew is arranged on the adjusting block, and one end of the jackscrew penetrates through the adjusting block to abut against the stop lever.

The stop lever passes through the clamp and is articulated with the lifting hook main part, the clamp is hookup with the lifting hook main part, and the stop lever is articulated with the clamp.

The clamp is provided with a connecting plate hinged with the stop lever, the connecting plate is connected with the clamp bolt, and the connecting plate is hinged with the stop lever.

Compared with the prior art, the utility model, the beneficial effect who has is:

the stop lever and the lifting hook main body are hinged, and one end of the stop lever is abutted to the lifting hook main body under the action of gravity by utilizing the lever principle, so that the hook opening of the lifting hook main body is closed. By adopting the mode, the whole structure is simplified, the use of easily damaged parts such as springs and the like is saved, and the service life is prolonged. Meanwhile, the adjusting block is arranged, so that the adjusting function can be achieved.

Detailed Description

The technical solutions in the embodiments of the present invention are described below clearly and completely, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 to 2, a crane hook fastener comprises a hook body 1 and a stop lever 2, wherein the stop lever 2 is hinged to the hook body 1, and the other end of the stop lever 2 generates a downward force under the action of gravity by using the lever principle, so that one end of the stop lever 2 rotates upwards around a hinge point to abut against the hook body 1, and a hook opening of the hook body 1 is closed.

The other end of the stop lever 2 is provided with an adjusting block 3, the adjusting block 3 is connected with the stop lever 2 in a sliding way, and the adjusting block 3 is provided with a corresponding sliding chute 300. Meanwhile, a jackscrew 4 is arranged on the adjusting block 3, and one end of the jackscrew 4 penetrates through the adjusting block 3 to be abutted against the stop lever 2. The distance between the adjusting block 3 and the hinge point is changed by moving the adjusting block, so that the adjusting arm is adjusted.

In the adjusting process, the jackscrew 4 is unscrewed, and then the adjusting block 3 is moved to a proper position; the jackscrew 4 is screwed, and one end of the jackscrew 4 penetrates through the sliding groove 300 of the adjusting block 3 to be abutted against the stop lever 2, so that the adjusting block 3 is limited to move, and a fixing effect is achieved.

Further, as shown in fig. 3, the blocking rod 2 may be directly hinged to the hook body 1, but a corresponding through hole needs to be formed in the hook body 1, which is inconvenient. Therefore, the stop lever 2 is hinged with the hook body 1 through the clamp 5, and holes are prevented from being formed in the hook body 1; the clamp 5 is connected with the hook main body 1, and the stop lever 2 is hinged with the clamp 5. During installation, the hoop 5 is connected with the neck part at the upper end of the lifting hook main body 1, and the stop lever 2 is hinged with the hoop 5, so that a corresponding through hole can be omitted on the lifting hook main body 1.

Further, as shown in fig. 4, in order to facilitate the installation, a connection plate 6 hinged to the stopper rod 2 is provided on the yoke 5, one end of the connection plate 6 is bolted to the yoke 5, and the other end of the connection plate 6 is hinged to the stopper rod 2. During installation, the clamp 5 is firstly connected with the neck part at the upper end of the lifting hook main body 1, and then one end of the connecting plate 6 is connected with the clamp 5 through bolts (the other end of the connecting plate 6 is hinged with the stop lever 2 in advance).

The specific structure of the above-mentioned clip 5 is well known to those skilled in the art, and it is mainly composed of two oppositely arranged snap rings, which are connected by means of bolts. The neck of the hook body 1 is hooked by a hook 5.

The above description has been made in detail only for the preferred embodiment of the present invention, but the present invention is not limited to the above embodiment, and various changes can be made without departing from the spirit of the present invention within the knowledge scope of those skilled in the art, and all such changes are intended to be encompassed by the present invention.
