Abstract
Description
Technical Field
[0001] This utility model specifically relates to the field of gantry crane lifting beam technology, and more specifically to a combined gantry crane lifting beam. Background Technology
[0002] In modern industry, gantry cranes, as large lifting equipment, are widely used in ports, railway freight yards, industrial and mining enterprises, bridge construction, and other scenarios due to their ability to vertically lift and horizontally transport heavy objects within a large working range. From loading and unloading containers at ports to installing and transporting large machinery in factories, and hoisting prefabricated bridge components, gantry cranes are indispensable key equipment, and their efficient and stable operation directly affects the progress and efficiency of production and construction.
[0003] The lifting girder, serving as the connecting bridge between the gantry crane and the load being lifted, is a core component ensuring the safety and efficiency of lifting operations. It not only needs sufficient strength and rigidity to bear the load but also must rationally distribute the load to prevent deformation or damage to the object during lifting. Furthermore, the performance of the lifting girder affects the overall stability and operational flexibility of the gantry crane, playing a decisive role in the quality and efficiency of lifting operations.
[0004] However, the traditional gantry crane lifting beams widely used in the market have many limitations. Structurally, traditional lifting beams are mostly fixed structures; their dimensions, shape, and load-bearing capacity are determined during the design and manufacturing process, making it difficult to adjust them according to different lifting needs. When dealing with irregularly shaped objects with uneven weight distribution, traditional lifting beams cannot adapt flexibly, potentially requiring the customization of special lifting beams, which significantly increases equipment procurement costs. Furthermore, these special lifting beams are used infrequently, resulting in resource waste. Utility Model Content

[0032] The end beam structure 1 and end beam structure 2 described above adopt the same structural composition;
[0033] The end beam structure 1 includes an inverted T-shaped base frame 11. Motor housings 13 are symmetrically mounted on the upper surface of the inverted T-shaped base frame 11. Rotary motors 14 are fixedly connected inside each motor housing 13. The ends of the rotary motors 14 are connected to their respective screws 15. The screws 15 are threadedly connected to the screw holes on the inner sides of both ends of the T-shaped base frame 11. The other end of the screws 15 is fixedly connected to a chassis 16 arranged in a ring.
[0034] By adopting the above technical solution, the combined gantry crane beam can quickly adapt to different ground height differences through the height adjustment system composed of the rotary motor 14, screw 15 and chassis 16. It does not require complex auxiliary equipment, reduces operational limitations and expands the application range. The motor 14 drives the screw 15 to adjust the height, which is faster and easier to operate than manual adjustment. It can complete the adjustment of the end beam structure and ground height in a short time, shorten the equipment debugging time and improve the operation efficiency.
[0035] In this embodiment, the lower surface of the T-shaped base frame 11 is symmetrically equipped with movable wheels 12, and the upper end is provided with a plurality of round holes 17 in a rectangular array, with the round holes 17 being provided through the upper end of the T-shaped base frame 11.
[0036] The T-shaped base frame 11 has a lower ear plate 18 symmetrically arranged on one side of its upper end. The lower ear plate 18 is fixed to the T-shaped base frame 11 by bolts. The inner side of the symmetrically arranged lower ear plate 18 is connected to the telescopic cylinder 19.
[0037] The upper end of the telescopic cylinder 19 is connected to the inner side of the upper ear plate 33. The upper ear plate 33 is symmetrically installed on one side of the telescopic frame 31, and the upper ear plate 33 is fixed to one side of the telescopic frame 31 by bolts.
[0038] The telescopic frame 31 is provided with multiple positioning holes 32 in a rectangular array. The positioning holes 32 are provided through the telescopic frame 31. The upper end of the telescopic frame 31 is fixedly connected to the connecting frame 34 by bolts. The upper end of the connecting frame 34 is fixedly connected to the hanging beam 35 by bolts.
[0039] By adopting the above technical solution, the telescopic cylinder 19 and the telescopic frame 31 are set so that the height of the lifting beam 35 can be flexibly adjusted according to the actual lifting needs. Through the bolt connection of the positioning hole 32 and the round hole 17, the position of the telescopic frame 31 can be stably fixed after adjustment, ensuring the safety and stability of the lifting process.
[0040] In this embodiment, the telescopic frame 31, positioning hole 32, upper ear plate 33 and connecting frame 34 are symmetrically arranged at both ends of the bottom of the lifting beam 35. The lifting beam 35 is provided with slide rails on both sides, and is slidably connected to the boom crane 4 through the slide rails.
[0041] One of the telescopic frames 31 is slidably connected to the inverted T-shaped base frame 11 at the bottom, and the positioning hole 32 on the telescopic frame 31 and the round hole 17 on the inverted T-shaped base frame 11 can be connected by bolts; the other telescopic frame 31 is also slidably connected to the end beam structure 2.
[0042] By adopting the above technical solution, the motor-driven method makes the end beam height adjustment process quick and convenient during installation. Compared with the traditional manual adjustment method, it greatly saves time and labor costs and improves the working efficiency of the equipment. At the same time, the sliding design of the boom crane 4 on the main beam structure 3 and the lifting beam 35 makes the lifting operation of goods more flexible and can quickly and accurately lift goods to the designated position.
[0043] The working principle of this utility model is as follows: When it is necessary to adjust the height of the end beam to adapt to different ground height differences, the rotary motor 14 is started, which drives the screw 15 connected to its end to rotate. When the screw 15 rotates, it will generate axial movement in the screw hole. The other end of the screw 15 is fixedly connected to the annular base 16. The axial movement of the screw 15 will drive the base 16 to move up and down, thereby realizing the height adjustment of the end beam structure to a certain extent.
[0044] When in use, the combined gantry crane beam can quickly adapt to different ground height differences through the height adjustment system composed of a rotary motor 14, a screw 15, and a chassis 16. It does not require complex auxiliary equipment, reduces operational limitations, and expands the application range. The motor 14 drives the screw 15 to adjust the height, which is faster and easier to operate than manual adjustment. It can complete the adjustment of the end beam structure and the ground height in a short time, shorten the equipment debugging time, and improve the operation efficiency.
[0045] When the telescopic cylinder 19 is working, it can push the telescopic frame 31 to move in and out along the sliding connection direction with the inverted T-shaped base frame 11. The telescopic frame 31 is provided with a plurality of positioning holes 32 arranged in a rectangular array. When the telescopic frame 31 is extended to the appropriate position, the positioning holes 32 can be connected to the round holes 17 on the inverted T-shaped base frame 11 by bolts to fix the position of the telescopic frame 31. The upper end of the telescopic frame 31 is fixedly connected to the connecting frame 34 and the hanging beam 35 in sequence by bolts, thereby connecting the end beam structure and the hanging beam 35 into one unit.
[0046] The telescopic cylinder 19 and the telescopic frame 31 allow the height of the lifting beam 35 to be flexibly adjusted according to actual lifting needs. The bolt connection between the positioning hole 32 and the round hole 17 can stably fix the position of the telescopic frame 31 after adjustment, ensuring the safety and stability of the lifting process.
[0047] During installation, the motor-driven method makes the end beam height adjustment process quick and convenient. Compared with the traditional manual adjustment method, it greatly saves time and labor costs and improves the working efficiency of the equipment. At the same time, the sliding design of the boom crane 4 on the main beam structure 3 and the lifting beam 35 makes the lifting operation of goods more flexible and can quickly and accurately lift goods to the designated position.
