Description

Technical Field

[0001] This invention relates to the field of attachments for container loading and unloading equipment, and more particularly to the crossbeam of a container bulk material tipping and unloading attachment. Background Technology

[0002] Multimodal transport, as an advanced mode of transportation, refers to a transport process jointly completed by two or more modes of transport that are interconnected and transshipped. Among the various modes of multimodal transport, container transport occupies an important position. Containers have advantages such as high standardization, good sealing, low damage rate, intensification, large scale, liner services, low cost, and high quality, which greatly improve the safety and efficiency of cargo transportation. Container reach stackers, as important equipment for container loading and unloading, are mainly used for stacking containers and horizontal transport within terminals and yards. They are widely used in container loading and unloading operations at small and medium-sized ports, railway transfer stations, and highway transfer stations, and can also be used as auxiliary equipment in large container terminals. When containers arrive at their destination, they need to be unpacked and the bulk materials unloaded. During this process, specialized equipment is required to tilt and lift the containers or flip them over as a whole. However, existing technology and equipment have obvious defects. For example, when connecting the original attachments to the tilting attachments of the front crane, the first large crossbeam on the attachments and the second large crossbeam of the tilting attachments are functionally redundant. The first large crossbeam is equipped with a hanger that connects to the crane's lifting arm. Both ends of the second large crossbeam are fixed with rotating arm seats, and a rotating frame connects the two rotating arm seats. This not only does not bring any additional advantages, but also increases the weight borne by the front crane's boom, which has an adverse effect on the service life and operational stability of the equipment. Summary of the Invention

[0003] The present invention provides a crossbeam for container bulk cargo tipping and unloading attachments, which overcomes the shortcomings of the prior art.

[0004] The technical solution adopted by the present invention to solve its technical problem is as follows: the crossbeam of the container bulk material tipping and unloading attachment includes a rectangular frame 1, in which a plurality of reinforcing ribs 11 and 12 are fixedly arranged at intervals along the length of the crossbeam; rectangular end plates 4 are fixedly provided at both ends of the rectangular frame 1, and the rectangular end plates 4 extend out of the rectangular frame 1 and are fixedly connected to the rotating arm seat 6; a first guide rail 2 and a second guide rail 3 are fixedly provided on the two first side walls located at the front and rear of the rectangular frame 1, the outer side wall of the first guide rail 2 and the bottom wall of the second guide rail 3 form a guide rail surface, the second guide rail 3 is located directly above the first guide rail 2 and the protrusion distance of the second guide rail 3 protruding from the first side wall is greater than the protrusion distance of the first guide rail 2 protruding from the first side wall.

[0005] In one embodiment: the reinforcing ribs 11 and 12 are divided into a first reinforcing rib 11 and a second reinforcing rib 12; the first reinforcing rib 11 has a rectangular structure and is adapted to be fixed to the inner wall of the rectangular frame 1; the second reinforcing rib 12 has a U-shaped structure and is fixed to the inner wall of the two first side walls and the bottom wall of the rectangular frame 1.

[0006] In one embodiment: a reinforcing rib 31 with a triangular cross-section is fixedly connected between the top wall of the second guide rail 3 and the first side wall.

[0007] In one embodiment: it connects to a hanger 5, which has two downwardly extending sides 51. The lower part of each side 51 has a connecting seat 52 extending outward. The side 51 clamps a rectangular frame 1 and the hanger 5 is located on the rectangular frame 1. The connecting seats 52 of the side 51 slide on the guide rail surfaces of the two first guide rails 2 and the guide rail surfaces of the two second guide rails 3, respectively.

[0008] In one embodiment: the first side wall of the rectangular frame 1 is fixed with an ear seat 13, and a side displacement cylinder unit 8 is also provided. The two ends of the side displacement cylinder unit 8 are respectively hinged to the ear seat 13 and the side 51.

[0009] Compared with the prior art, this technical solution has the following advantages:

[0010] The crossbeam can not only connect to the front-end crane's hanger via the first and second guide rails, but also connect to the rotating arm seat via the rectangular end plate, reducing cost and weight, and is reinforced with ribs to enhance strength. Attached Figure Description

Detailed Implementation

[0018] Please refer to Figures 1 to 5 The crossbeam of the container bulk cargo tipping and unloading attachment includes a rectangular frame 1, within which multiple reinforcing ribs 11 and 12 are fixedly arranged at intervals along the length of the crossbeam; a first guide rail 2 and a second guide rail 3 are fixedly mounted on the front and rear first side walls of the rectangular frame 1, the second guide rail 3 being directly above the first guide rail 2 and the protrusion of the second guide rail 3 outward from the first side wall being greater than the protrusion of the first guide rail 2 outward from the first side wall, the outer side wall of the first guide rail 2 and the bottom wall of the second guide rail 3 both forming guide rail surfaces; the rectangular frame 1 is connected to a lifting bracket 5, the lifting bracket 5 Two downward-extending side portions 51 are provided, and connecting seats 52 are extended from the lower part of the two side portions 51. The two side portions 51 clamp the rectangular frame 1 and the hanger 5 is located on the rectangular frame 1. The connecting seats 52 of the two side portions 51 are respectively slidably connected to the outer side wall (guide rail surface) of the two first guide rails 2, and the connecting seats 52 of the two side portions 51 are respectively slidably connected to the bottom wall (guide rail surface) of the two second guide rails 3. In this way, the hanger 5 and the crossbeam are precisely and stably connected together, and the crossbeam can move laterally relative to the hanger 5 to adapt to different operating scenarios and container position adjustment needs. Rectangular end plates 4 are fixed at both ends of the rectangular frame 1. These end plates 4 extend beyond the rectangular frame 1 on all four sides and are used to secure the rotating arm seats 6. Mounting holes are provided in the extended areas, through which the rotating arm seats 6 are fixed to the rectangular end plates 4. A rotating frame 7, capable of flipping, is connected between the two rotating arm seats 6, allowing the container to be locked with a rotary lock and thus flipped for unloading. The design and connection method of the end plates have been carefully optimized to ensure structural strength and stability under heavy loads, guaranteeing the safe and reliable operation of the entire unloading process. In this specific embodiment, the crossbeam connects not only the lifting frame but also the rotating arm seats.

[0019] The reinforcing ribs 11 and 12 are divided into a first reinforcing rib 11 and a second reinforcing rib 12. The first reinforcing rib 11 has a rectangular structure and is fitted and fixed to the inner wall of the rectangular frame 1. The second reinforcing rib 12 has a U-shaped structure and is fixed to the inner wall of the two first side walls and the bottom wall of the rectangular frame 1. The reinforcing ribs 11 and 12 can greatly enhance the strength and load-bearing capacity of the beam structure. In actual operation, the beam needs to bear the huge weight from the container and the bulk materials inside. The reinforcing ribs with different heights (the first reinforcing rib 11 of the rectangular structure is high, and the second reinforcing rib 12 of the U-shaped structure is low) and reasonable distribution can effectively disperse stress, prevent the beam from deforming or being damaged during the stress process, extend the service life of the beam, and improve the reliability of the equipment.

[0020] The top wall of the second guide rail 3 and the first side wall are fixedly connected to a reinforcing rib 31 with a triangular cross-section to enhance the connection strength.

[0021] The first side wall of the rectangular frame 1 is fixed with an ear seat 13 and is also equipped with a side-shifting hydraulic cylinder unit 8. The two ends of the side-shifting hydraulic cylinder unit 8 are respectively hinged to the ear seat 13 and the side 51. In container loading and unloading operations, the side-shifting function enables the crossbeam and the attachments connected to it to be finely adjusted in the horizontal direction, which facilitates the precise positioning and loading and unloading of containers, and improves the accuracy and efficiency of the operation.

[0022] The above description is merely a preferred embodiment of the present invention, and therefore should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of the patent and the contents of the specification should still fall within the scope of the present invention.
