Description

Technical Field

[0001] This utility model relates to the field of hoisting technology, and specifically to a gantry crane system with precise adjustment function. Background Technology

[0002] Gantry crane systems, as important lifting devices, are crucial tools for equipment hoisting and play a key role in industries such as construction, bridges, and shipbuilding. Their core structure consists of components such as trusses, booms, winches, and pulley blocks, featuring structural stability, flexible operation, high load-bearing capacity, and wide applicability. However, in practical applications, gantry crane systems may encounter problems with precise adjustment of the hoisting position in certain situations. For example, uneven hoisting sites may require specific angles and positions for hoisting; additionally, the characteristics and shape of the object being hoisted can also affect precise positioning. Traditional gantry crane systems mostly employ relatively simple mechanical structures and control methods, lacking high-precision adjustment mechanisms. During hoisting, operators often rely solely on experience and intuition to adjust the hoisting position, leading to insufficient hoisting accuracy. Especially in situations requiring high-precision positioning, such as the handling and installation of precision equipment, traditional gantry crane systems often fail to meet the requirements. With the development of modern industry, the demands for hoisting accuracy are increasing, thus necessitating a gantry crane system capable of precise adjustment to adapt to diverse gantry crane needs. Utility Model Content

At the same time, the hoisting component can meet the adjustment requirements in the vertical direction, so as to adapt to occasions requiring precise hoisting, making the gantry crane system more flexible, improving the adaptability of the gantry crane system, and further improving the accuracy of cargo hoisting.

[0007] Furthermore, the first displacement component includes a first adjusting rail, a first moving member, and a first moving motor. The first adjusting rail and the first moving motor are respectively mounted on the walking frame.

[0011] Furthermore, the second displacement component includes a second adjusting rail, a second moving member, and a second moving motor. The second adjusting rail is formed on the first moving member, and the second moving motor is mounted on the first moving member.

[0015] Furthermore, the hoisting assembly includes a winch motor, an adjusting assembly, and a cable. The winch motor is mounted on the second moving member.

[0016] Based on the above-mentioned technical means, the hoist motor has precise control capability, which can precisely control the vertical displacement of the adjustment component through the cable, reducing the difficulty and complexity of operation, thereby improving the accuracy of the vertical displacement of the adjustment component.

[0017] Furthermore, the adjustment assembly includes a support base and multiple lifting components, the support base being connected to the cable; one end of each lifting component is mounted on the support base, and the other end is used for lifting goods.

[0018] According to the above-mentioned technical means, by combining the support base with multiple lifting components, the force generated during the hoisting process can be more effectively dispersed, thereby enhancing the hoisting stability and avoiding safety problems caused by excessive force on a single point; moreover, the multiple lifting components can cooperate with each other to adjust the posture of the goods, prevent the goods from shifting or shaking during the hoisting process, and ensure that the goods are hoisted smoothly; at the same time, the multiple lifting components can cooperate with each other to adapt to goods of different shapes, improving the applicability of the adjustment components.

The second displacement assembly 230 is mounted on the first displacement assembly 220 and configured to move along a second direction B on the first displacement assembly 220.

[0038] When goods need to be hoisted to the target position, the operator controls the traveling mechanism 200 to move above the goods and controls the hoisting component 300 to lift the goods. Then, the traveling mechanism 200 moves along the guide rail 100 to above the target position. At this point, the position of the goods and the target position may not correspond vertically. Therefore, it is necessary to utilize the first displacement component 220 and the second displacement component 230 to...
