Description

Technical Field

[0001] The utility model relates to the technical field of material grabbing and transferring equipment, in particular to a grab bucket with an external rib plate. Background Art

[0002] Bulk cargo handling has always been the main mode of port operation in modern port operations. When using 40-ton and low-tonnage gantry cranes, the ports use the traditional two-piece grab bucket as the optional grab bucket. The bucket body structure is a main rib plate inside the bucket body, which is a commonly used structure for two-piece grab buckets.

[0003] However, this form has certain disadvantages. The existing grab bucket usually adopts a structure with a rib plate on the inside of the bucket body. During operation, a certain resistance will be generated when grabbing materials. The rib plate structure forms a right angle with the bucket body, causing material extrusion, and material accumulation and residue during loading and unloading. In addition, since the main board structure forms a small box structure, it will occupy part of the bucket body volume, reducing the weight of the grabbed material and failing to achieve the maximum bucket capacity utilization.

[0004] In order to solve the above problems, we have made improvements and proposed a grab with external ribs. Utility Model Content

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] The utility model provides a grab bucket with an external rib plate, comprising an upper supporting beam and a grab bucket body, wherein the external top surface of the upper supporting beam is movably provided with a lifting beam, the bottom of the upper supporting beam is movably provided with an upper supporting beam fixed pulley group, the four corners of the upper supporting beam are rotatably connected with support rods through pin shafts, a middle beam movable pulley group is provided below the upper supporting beam fixed pulley group, two groups of opening and closing movable brackets are movably provided below the middle beam movable pulley group, the two groups of opening and closing movable brackets are respectively located at the lower left and lower right of the middle beam movable pulley group, and the outer surfaces of the two halves of the grab bucket body are respectively fixedly welded to the inner sides of the two groups of opening and closing movable brackets.

[0007] As an optimal technical solution of the present invention, a hinge seat is fixedly welded at the center of the top surface of the upper supporting beam, the middle part of the outer surface of the lifting beam is hinged to the upper supporting beam through the hinge seat, and a wire rope controller is provided at the left and right ends of the front and rear of the lifting beam. The wire rope controller consists of two splints and two fixed shafts. The two splints are parallel to each other and the bottoms are fixedly welded to the top surface of the upper supporting beam. The two fixed shafts are respectively located at the left and right ends of the top between the two splints, and the front and rear ends of the fixed shafts are respectively fixedly welded to the two splints. The wire rope controller is fixedly wound with a wire rope through the fixed shaft.

[0008] As an optimal technical solution of the present invention, a first bearing seat is fixedly welded on the bottom surface of the upper supporting beam, and the upper supporting beam fixed pulley group is rotatably connected to the upper supporting beam through the first bearing seat. A motor is fixedly installed in the middle part of the inner part of the upper supporting beam, and the central axis of the upper supporting beam fixed pulley group is coaxially fixedly connected with the rotating shaft of the motor. The two groups of opening and closing movable brackets are each composed of two main ribs, and the bottoms of the four support rods are respectively rotatably connected to the middle parts of the four main ribs of the two groups of opening and closing movable brackets through pin shafts. A middle beam box is provided below the upper supporting beam fixed pulley group.

[0009] As an optimal technical solution of the present invention, a second bearing seat is fixedly welded on the top surface of the center beam box, the center beam movable pulley group is rotatably connected to the center beam box through the second bearing seat, and the tops of the four main ribs of the two groups of the opening and closing movable brackets are rotatably connected to the front and back centers of the center beam box.

[0010] As an optimal technical solution of the present invention, the opposite surfaces of the two main ribs of each group of the opening and closing movable brackets are provided with bottom ribs, a connecting plate is fixedly welded between the bottom ribs and the main ribs, the front and rear end edges of the two halves of the grab bucket body are fixedly welded with side sealing plates, and the middle parts of the front and back sides of the two groups of opening and closing movable brackets are fixedly welded with reinforcing rods, and the bottom ends of the four reinforcing rods are fixedly welded to the top ends of the middle parts of the inner walls of the four side sealing plates.

[0011] As an optimal technical solution of the present invention, support legs are provided at the opening and closing positions on the front and back sides of the two-lobed grab bucket body, the bottom back sides of the four support legs are fixedly welded to the four side sealing plates respectively, the tops of the four support legs are rotatably connected to the center beam box through pin shafts, and a cutting edge plate is fixedly welded at the edge of the opening and closing position of the bottom surface of the two-lobed grab bucket body.

[0012] The beneficial effects of the present invention are as follows: with this type of grab bucket having external ribs, after the ribs are arranged on the outside of the bucket body, when grabbing materials with relatively high viscosity, there is no longer any right-angle obstruction in the space inside the bucket body, the resistance is small, the accumulation of materials is reduced, and when the empty bucket is opened and running, sticky materials are less likely to fall, which can effectively reduce damage to terminal equipment and the hull of docked ships. At the same time, when grabbing goods, the stress bending degree of the blade edge plate at the bottom of the bucket body is slightly reduced, and the wear of the ribs is reduced. When the grab bucket is fully loaded, the external ribs can free up more space in the bucket body, grab more materials, and improve working efficiency. In addition, when the empty bucket is placed, the stability of the bucket body is relatively better. BRIEF DESCRIPTION OF THE DRAWINGS
