Description

Technical Field

[0001] This utility model relates to the technical field of lifting devices, specifically to a cross-shaped lifting beam structure. Background Technology

[0002] Lifting devices in lifting machinery are units used to lift heavy objects. The most commonly used lifting devices are hooks and slings. Others include lifting rings, lifting suction cups, clamps, and forks. They also include cross-beam structures, which are integrated cross-shaped structures with booms hinged to each of the four beams. A lifting ring for connecting to the hook in the lifting machinery is installed at the center of the top of the cross-beam.

[0003] Overhead cranes, as a type of lifting machinery, are particularly used in industrial and construction environments. They primarily move heavy objects horizontally and vertically, and are commonly found in factories, warehouses, and construction sites. When hoisting large, heavy components in a workshop, a single overhead crane may not be able to bear the weight. In such cases, two overhead cranes operating side-by-side are needed to lift simultaneously to meet the required weight. However, current cross-shaped lifting beam structures only have a lifting ring at the center of the top for connection to the lifting machinery, making them unsuitable for two overhead cranes. Furthermore, the integrated structure leads to localized stress concentration in the cross beam, limiting its load-bearing capacity. Therefore, a cross-shaped lifting beam structure is needed to be designed for hoisting large, heavy objects in a workshop. Utility Model Content

By setting separate upper and lower beam structures and combining them with the setting of lifting components, the load can be reasonably distributed, and the rigidity and stability of the cross-shaped lifting beam structure can be improved. It is used for lifting large heavy objects by two overhead cranes.

[0005] To achieve the above and other related objectives, this utility model provides a cross-shaped suspension beam structure, comprising:

Detailed Implementation

[0024] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0025] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the illustrations only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0026] See Figure 1This utility model provides a cross-shaped lifting beam structure, including an upper beam, a lower beam, and a lifting unit. The upper beam includes an upper beam body 10; the lower beam includes a lower beam body 20. The upper beam body 10 and the lower beam body 20 are arranged in a cross shape, and the upper beam body 10 is located above the lower beam body 20 and is fixedly connected. The lifting unit includes a pair of first lifting components 31 and a plurality of second lifting components 32. The pair of first lifting components 31 are respectively located at both ends of the upper beam body 10, and at least two second lifting components 32 are respectively provided on the upper beam body 10 and the lower beam body 20. Each first lifting component 31 and each second lifting component 32 includes a horizontally arranged lifting rod, and a lifting plate assembly is installed on the lifting rod of each second lifting component 32.

[0027] In use, the pair of booms of the first lifting assembly 31 are connected to the hooks of the two overhead cranes using wire ropes, and the boom of the second lifting assembly 32 is connected to the lifting point of the load using wire ropes. The second lifting assembly 32 on the upper beam body 10 and / or the lower beam body 20 can be used as needed. When the lifting point of the load is perpendicular to the direction of travel, the second lifting assembly 32 on the upper beam body 10 can be used; when the lifting point of the load is parallel to the direction of travel, the second lifting assembly 32 on the lower beam body 20 can be used. Therefore, the cross-shaped lifting beam structure of this utility model can lift loads with lifting points perpendicular to each other. Furthermore, the upper beam body 10 is located above and fixedly connected to the lower beam body 20. A pair of first lifting components 31 are provided at both ends of the upper beam body 10. The pair of lifting rods of the first lifting components 31 are respectively connected to the hooks of two cranes by steel wire ropes. This is suitable for two cranes in the workshop to lift large heavy objects. At the same time, this separate structural design allows the upper beam and the lower beam to independently bear the load according to the load conditions, thereby achieving a more reasonable stress distribution, effectively reducing local stress concentration, and improving the overall load-bearing capacity of the structure.

[0028] In one embodiment of the present invention, each first hoisting assembly 31 includes a pair of first side plates 311 and a first lifting rod 312. The pair of first side plates 311 extend along the end of the upper beam body 10, and the first lifting rod 312 is horizontally inserted into the pair of first side plates 311. Reinforcing plates are attached to both sides of each first side plate 311, and a first connecting plate 313 is provided at the lower end of the pair of first side plates 311.

[0029] It should be noted that the first side plate 311 and the first connecting plate 313 are integrally formed or fixedly connected to the upper beam body 10, respectively. The first hanger 312 is horizontally inserted into a pair of first side plates 311. The first hanger 312 can be a lifting pin. A pair of anti-rotation baffles 40 are provided on both sides of the insertion hole of the lifting pin to prevent the lifting pin from rotating and to fix the lifting pin.

[0030] In one embodiment of the present invention, each second hoisting assembly 32 includes a second side plate 321 and a second hoisting rod 322. The second side plate 321 and the side of the upper beam body 10 or the side of the lower beam body 20 are correspondingly spaced apart and are fixedly connected to the corresponding side by a second connecting plate 323. The second hoisting rod 322 is horizontally inserted into the second side plate 321 and the corresponding side.

[0031] It should be noted that the second lifting rod 322 can be a lifting point pin. A pair of anti-rotation baffles 40 are provided on both sides of the insertion hole of the lifting point pin to prevent the lifting point pin from rotating and to fix the lifting point pin.

[0032] In one embodiment of this utility model, a pair of mounting plates 21 are spaced apart at the middle of the lower beam body 20. The upper beam body 10 is positioned at the upper end of the lower beam body 20 between the pair of mounting plates 21 and connected by connecting pins 22. A pair of anti-rotation baffles 40 are provided on both sides of the corresponding pin hole of each connecting pin 22. Each mounting plate 21 is an inverted U-shaped plate, with both sides of the mounting plate 21 correspondingly snapped onto the lower beam body 20. The bottom of the mounting plate 21 extends out of the upper end of the lower beam body 20. At this time, the connecting pin 22 can pass through the bottom protruding end of the mounting plate 21 and its corresponding upper beam body 10. The parallel arrangement of connecting pins 22 makes the connection more stable. A pair of anti-rotation baffles 40 are provided on both sides of the corresponding pin hole of each connecting pin 22 to prevent the connecting pin 2 from rotating, thereby achieving a fixed connection between the upper beam body 10 and the lower beam body 20.

[0033] It should be noted that the upper beam body 10 and the lower beam body 20 are designed independently and connected at the middle. This separate structure allows for better adaptation to load changes by adjusting the design of the upper beam body 10 and the lower beam body 20, thereby improving load-bearing capacity. It also effectively adjusts the load transfer path, improving the overall stress state and resulting in superior performance under heavy loads. Furthermore, the use of an inverted U-shaped plate as the mounting plate 21 also helps to bear a portion of the load.

[0034] In one embodiment of the present invention, both the upper beam body 10 and the lower beam body 20 are hollow plate frame structures. Each end of the upper beam body 10 and the lower beam body 20 is provided with a second hoisting assembly 32 on each of its two corresponding sides. Each side of the mounting plate 21 on each of its two corresponding sides of the lower beam body 20 is provided with a second hoisting assembly 32.

[0035] It should be noted that the number and position of the second lifting components 32 installed on the upper beam body 10 and the lower beam body 20 can be selected as needed. To ensure even load distribution when lifting heavy objects, the second lifting components 32 are arranged symmetrically. Specifically, the second lifting components 32 are symmetrically arranged on the upper beam body 10 with the lower beam body 20 as the axis of symmetry, and on the lower beam body 20 with the upper beam body 10 as the axis of symmetry. Furthermore, when the second lifting components 32 are located on the sides of the upper beam body 10 or the lower beam body 20, they are installed on both corresponding sides.

[0036] In one embodiment of the present invention, each hanging plate assembly includes a first hanging plate 51 and a pair of second hanging plates 52. One end of the first hanging plate 51 is fitted onto the hanging rod, and the other end of the first hanging plate 51 is connected to the pair of second hanging plates 52. A hanging shaft 53 is inserted between the pair of second hanging plates 52.

[0037] In one embodiment of the present invention, each hanging plate assembly includes a first hanging plate 51 and a hanging ring 54. One end of the first hanging plate 51 is fitted onto the hanging rod, and the other end of the first hanging plate 51 is connected to the hanging ring 54.

[0038] It should be noted that the above two types of lifting plate assemblies are designed to match the structures of different lifting points for heavy objects. When the structure of the lifting point has a perforation, a lifting plate assembly with a lifting shaft 53 inserted between a pair of second lifting plates 52 can be used, allowing the lifting shaft 53 to pass through the perforation and lift the heavy object. When the structure of the lifting point has a hook, a lifting plate assembly with a lifting ring 54 can be used. Alternatively, if there is a distance between the overhead crane height and the lifting point of the heavy object, but the wire rope is too long to use, a lifting plate assembly with a lifting ring 54 can meet the height requirements. Therefore, the lifting plate assembly of this utility model is suitable for the structures of different lifting points for heavy objects, including but not limited to the structures of the two types of lifting points mentioned above.

[0039] In summary, the cross-shaped lifting beam structure of this utility model, employing a split upper and lower beam design, not only allows for the separate design of the upper and lower beams to enhance the overall load-bearing capacity as needed, but also enables effective adjustment of the load transfer path through a rational design of the connection method between the upper and lower beams. This improves the overall stress state, resulting in superior performance under heavy loads. It is suitable for use with two overhead cranes in a workshop for lifting large, heavy objects.
