Description

A dredging grab device

technical field

The utility model relates to a grab device, in particular to a dredging grab device.

Background technique

With the continuous development of ports and shipping, the dredging of ports and waterways has become indispensable. In the dredging process, ship dredging is a very important link. The efficiency of dredging affects the progress of the whole project. The dredging work is completed by the dredging grab device.

The existing dredging grab device comprises a balance beam, an upper box, a lower box, an upper pulley, a lower pulley, two support rods and two buckets, the upper box is positioned below the balance beam and is fixedly mounted on the balance beam, The upper pulley is fixedly installed on the upper box, the lower pulley is fixedly installed on the lower box, the lower box is located below the upper box, the upper pulley and the lower pulley are connected by a wire rope, and the wire rope is wound on the upper pulley. The upper ends of the two support rods Symmetrically hinged on the upper box, the lower ends of the two support rods are hinged with the two buckets one by one, and the two buckets are symmetrically hinged on the lower box. In order to reduce the resistance of the bucket entering the mud, the bucket is equipped with Bucket teeth, in the initial state, the two bucket bodies are closed, and the bucket teeth on the two bucket bodies mesh at this time. When working, the lifting mechanism on the ship first puts the dredging grab device into the dredging position in the water, the upper pulley rotates to elongate the wire rope, the lower box moves downward under the action of gravity, and the two closed buckets are separated and Go into the mud and grab the mud. At this time, the upper pulley rotates reversely to shorten the wire rope, the lower box is pulled up, and the two buckets move closer together with the rise of the upper box until they are closed. The mud is grabbed by the two buckets. The lifting mechanism above lifts the dredging grab device and unloads the silt, completes a silt grabbing, and goes round and round until the dredging work is completed.

However, the existing dredging grab device has the following problems: during the lifting process, the two bucket bodies are subjected to relatively high resistance when rising, and the teeth engaged on the two bucket bodies are easily misaligned and gaps appear, so that the dredging grab device is closed The performance is not good, and it is easy to leak during the dredging process.

When the two buckets are closed, the power is turned on, and the electromagnets in the two buckets are adsorbed together.

The rear end of the electromagnet is connected with the bucket through a spring.

The electromagnet includes a protective shell, a steel plate and an enameled wire arranged in the steel plate, the protective shell is installed in the bucket and covered on the steel plate, and the outer wall of the steel plate is provided with threaded groove, the enameled wire is wound in the groove, the winding direction of the enameled wire on the two steel plates is opposite, the enameled wire is connected to the power supply, and the steel plate can be The bucket moves left and right, and when the two buckets are closed, the power is turned on, and the steel plates in the two buckets are adsorbed together.

The front end of the steel plate is provided with a cutting edge, and the material of the cutting edge is 16Mn low alloy steel.

Compared with the prior art, the utility model has the advantage that an electromagnet that can move left and right is arranged on the inner wall of the bottom of each bucket, and the electromagnet is connected to the power supply. When the two buckets are closed, the power is turned on, and the two The electromagnets in the two buckets are adsorbed together. During the dredging process, when the two buckets grab the silt and then close, the electromagnets in the two buckets are adsorbed together, thereby enhancing the combination between the two buckets. Strong force, to ensure the stable combination of the two buckets, good closure, during the lifting process, the teeth meshing on the two buckets are not easy to dislocate, and it is not easy to leak during the dredging process;

When the rear end of the electromagnet is connected to the bucket body through a spring; when the power is turned on, the electromagnets in the two buckets are attracted, and the spring stretches. When the power is turned off, the spring shrinks to make the electromagnet reset automatically, and the operation is convenient;

When the front end of the steel plate is provided with a cutting edge, and the material of the cutting edge is 16Mn low-alloy steel, the toughness and wear resistance of the electromagnet are improved.
