[0002] As a key component in the industrial field, large structural parts have an extremely important status and role. By definition, large structural parts usually have super-large dimensions, complex and diverse shapes, and can bear considerable load pressure. Generally, their length, width and height dimensions all show a magnificent scale, and the length often extends to several meters or even tens of meters. The width and height should not be underestimated. In industries such as wind power generation, there is a huge demand for vehicle loading and unloading and transportation of various types of large structural parts (nacelles, wheel hubs) weighing tens to hundreds of tons; large structural parts (nacelles, wheel hubs) are generally loaded on ground-based transport platforms. During loading and unloading, the large structural parts need to be lifted from the ground together with the platform and loaded on the transport vehicle, or lifted from the vehicle and unloaded to the ground.

[0003] At present, heavy-duty truck cranes are used for loading and unloading large structural parts in most cases. Heavy-duty truck cranes with a load-bearing capacity of hundreds of tons are huge in size and occupy a very large area when deployed. When loading and unloading large structural parts, a spacious site is required, which significantly reduces the site utilization rate of large structural parts. In addition, the purchase and use costs of heavy-duty truck cranes are very high, and the economic efficiency is poor. Therefore, a hydraulic lifting device for large structural parts is proposed.

[0027] Example 1: Figure 1-6As shown, the utility model provides a large structural member hydraulic lifting device, including a lift base 1, and a lift support frame 1 2 and a lift support frame 2 3 fixedly connected on both sides of the upper part of the lift base 1, the lift support frame 1 2 and the lift support frame 2 3 are fixedly installed with a lift top plate 4 at one end away from the lift base 1 by bolts, and two identical reinforcement plates 5 are fixedly installed between the lift support frame 1 2 and the lift support frame 2 3 by bolts, and a hydraulic jacking wheel 6 is provided at the lower part of the lift base 1. A battery assembly 7 and a manual hydraulic pump 15 are fixedly installed on one side of the lift support frame 2 3, and a hydraulic servo pump station 8 and a control box 9 are installed in sequence from bottom to top on one side of the lift support frame 2 3 away from the lift support frame 1 2. Two identical guide rails 10 are fixedly installed on the opposite surfaces of the lift support frame 1 2 and the lift support frame 2 3 by bolts, and a hydraulic lifting assembly 11 is arranged between the two guide rails 10. A wireless transmitter 13 is fixedly installed on the top of the lift top plate 4, and a wire displacement sensor 12 is fixedly installed on the top of the lift base 1.

[0028] Specifically, a through slot for the hydraulic lifting assembly 11 is defined in the center of the top of the lifter's top plate 4. The cross-sections of the lifter support frames 1 and 2, 3, are L-shaped, and a plurality of equally spaced reinforcing ribs 14 are provided on the outsides of the lifter support frames 1 and 2. Advantageously, the L-shaped design of the lifter support frames 1 and 2 improves both support capacity and stability, while the equally spaced reinforcing ribs 14 enhance the strength of the lifter support frames 1 and 2.

[0029] Specifically, the hydraulic lifting assembly 11 includes a hydraulic cylinder 1102, which is fixedly mounted on the top of the lift base 1. A movable block 1101 is fixedly mounted on the movable end of the hydraulic cylinder 1102, and a movable shovel foot 1103 is fixedly mounted on the front side of the movable block 1101. A rotating shaft 1104 is provided on both sides of the movable block 1101. A guide wheel 1105 is rotatably mounted on the outer side of the movable block 1101 via the rotating shaft 1104.

[0030] Specifically, three hydraulic jacking wheels 6 are provided, arranged in a "∴" shape on the upper portion of the lift base 1. Advantageously, the manual hydraulic pump 15 can supply oil to the three hydraulic jacking wheels 6, which can lift the lift base 1 off the ground, thereby enabling the entire large-structure hydraulic lifting device to be moved.

[0032] Specifically, four identical sets of rotating shafts 1104 and guide wheels 1105 are provided, and the four sets of rotating shafts 1104 and guide wheels 1105 are symmetrically distributed about the centerline of the movable block 1101.

[0035] Working principle: During the loading process of large structural parts, four sets of large structural part hydraulic lifting devices are arranged at the front and rear positions on both sides of the grounded large structural parts and the transport platform, and the movable shovel foot 1103 is inserted into the support port of the large structural part transport platform. The external controller controls the four sets of large structural part hydraulic lifting devices to rise at the same time, and the four sets of hydraulic lifting assemblies 11 rise at the same time to lift the large structural parts and the transport platform from the ground to a height higher than the loading platform of the transport vehicle. The transport vehicle reverses and drives the loading platform under the large structural part transport platform. The external controller controls the four sets of large structural part hydraulic lifting devices to descend at the same time until the large structural parts and the transport trolley fall onto the loading platform of the transport vehicle. During the unloading process of large structural parts, the movable shovel foot 11 is 03 is inserted into the support port of the transport platform; the external controller controls four sets of large-structure hydraulic lifting devices to lift the large-structure and the transport platform until they are separated from the loading platform of the transport vehicle; when the transport vehicle leaves, the external controller controls four sets of large-structure hydraulic lifting devices to lower the large-structure and the transport platform to the ground, and separate the movable shovel foot 1103 from the transport trolley. During the lifting process, the manual hydraulic pump 15 can supply oil to the three hydraulic jacking wheels 6, and the hydraulic jacking wheels 6 can lift the lifter base 1 off the ground. At this time, the entire large-structure hydraulic lifting device can be moved. During the lifting process of the movable shovel foot 1103, the design of the guide wheel 1105 and the guide rail 10 can facilitate the guidance of the movable block 1101 to ensure that the movable block 1101 is lifted and lowered smoothly.
