AI Technical Summary
The working range of existing hydraulic clamshell buckets is limited by the fixed length of the boom and stick, making them unsuitable for situations with large water level differences.
The modular design allows for switching between the dual-rope and hydraulic clamshell buckets through interchangeable upper mechanisms, including the articulated connection between the left and right halves of the bucket. Combined with dual-rope control components and hydraulic control components, this enables flexible switching of the clamshell buckets.
The modular design enables flexible switching of the shell bucket, expanding the working range and adapting to the operational needs of different water level differences.

Abstract
Description
Technical Field
[0001] This invention relates to the field of material handling machine technology, specifically to a dual-purpose (double rope and hydraulic) clamshell bucket. Background Technology
[0002] With the increasing demand for material handling at ports and terminals, higher and higher requirements are being placed on material handling equipment. Clamshell buckets, as commonly used equipment for bulk material handling, are widely used in various ports and terminals.
[0003] The existing excavator clamshell bucket is a hydraulic clamshell bucket. The clamshell bucket's connecting frame is connected to the hydraulic grabber's boom via a pin. The front end of the boom has a pre-installed interface for hydraulic lines, which is connected to the oil port on the clamshell bucket via a hydraulic hose. The opening and closing of the clamshell bucket is achieved by a hydraulic cylinder, and the lifting of the clamshell bucket is achieved by a combined action of the hydraulic grabber's boom and boom.
[0004] Once the boom and stick lengths of the existing solution are determined, the working range is fixed. When the water level difference is large, the working range may be insufficient, thus limiting its application. Summary of the Invention
[0005] The present invention aims to solve the technical problems mentioned in the background section above, and provides a dual-rope and hydraulic shell bucket with a modular design, which allows for switching between the two types of shell buckets through the interchange of the upper mechanism.
[0006] The present invention provides a dual-rope and hydraulic dual-purpose clamshell bucket, comprising a left half-bucket and a right half-bucket. The left half-bucket has a fan-shaped side, with a central shaft at the intersection of its two straight sides. The central shaft is fixedly connected to the front and rear sides of the left half-bucket. Multiple first hinge seats are fixedly connected to the central shaft, and second hinge seats are also fixedly connected to the central shaft. The hinge holes of the first and second hinge seats are not on the same plane as the two perpendicular lines from the central shaft. Multiple third hinge seats are fixedly connected to the end of the left half-bucket away from the right half-bucket. The left and right half-buckets have the same structure. The left and right half-buckets are connected to a dual-rope control assembly through the third and first hinge seats, and the left and right half-buckets are connected to a hydraulic control assembly through the second and first hinge seats.
[0007] In some embodiments, the dual-rope control assembly includes an upper connecting frame, an upper pulley block, a lower connecting frame, a lower pulley block, a connecting rod, and a wire rope. The lower end of the upper connecting frame is fixedly connected to the upper pulley block, and the upper end of the lower connecting frame is fixedly connected to the lower pulley block. The lower end of the lower connecting frame is hinged to the first connecting seat of the left half-bucket via a pin. The upper end of the connecting rod is rotatably connected to the upper connecting frame, and its lower end is hinged to the third hinge seat of the left half-bucket via a pin. The upper pulley block and the lower pulley block are connected by a wire rope.
[0008] In some embodiments, the double-rope connection assembly is connected to the right half-bucket in the same way as the left half-bucket.
[0009] In some embodiments, the hydraulic control assembly includes a top frame, connecting plates, and a hydraulic cylinder. Two connecting plates are fixedly connected to the lower ends of the top frame. The lower end of the connecting plates is hinged to the first hinge seat of the left half-bucket via a pin on the side near the left half-bucket and to the first hinge seat of the right half-bucket via a pin on the side near the right half-bucket. The hydraulic cylinder is rotatably connected to the middle of the lower end of the top frame, and the lower end of the hydraulic cylinder is hinged to the second hinge seat of the left half-bucket via a pin.
[0010] In some embodiments, the right half-bucket is connected to the hydraulic control assembly in the same way as the left half-bucket.
[0011] In some embodiments, the upper end of the upper connecting frame is fixedly connected to a connector that is connected to the host.
[0012] In some embodiments, the upper end of the top frame is fixedly connected to a connector for connection with the main unit.
[0013] The advantages of this invention over the prior art are that, through modular design and simple disassembly and replacement, the switching between double-rope shell bucket and hydraulic shell bucket can be realized, and one set of equipment can be matched with multiple complete machines.
[0014] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description
