Description

Climbing device, climbing system, climbing lifting system and climbing method

technical field

The invention relates to a climbing technology of a mechanical mechanism, in particular to a climbing device, and also to a climbing system, a climbing lifting system and a climbing method.

Background technique

In recent years, the wind power industry has maintained rapid development, and the global installed capacity of wind power has exceeded 70 million kilowatts. The characteristics of wind power generation determine that wind farms are mostly located in areas such as hills, deserts, beaches, and offshore areas that are sparsely populated and have harsh natural environments.

A wind power generation system generally includes a wind turbine tower, blades and a wind turbine nacelle, and a generator, a gearbox, and a main shaft are installed in the wind turbine nacelle. The blades and the fan nacelle are installed on the top of the fan tower, and the blades can rotate under the action of the wind to drive the generator in the fan nacelle to generate electricity.

When large parts such as gearboxes, generators, and blades have major faults, and the top of the fan tower cannot be repaired or needs to be replaced, it is necessary to disassemble the faulty parts and transport the faulty parts to the ground with a crane; during installation, also A crane is required to transport the repaired or replaced parts to the top of the wind turbine tower for installation. At present, the height of the wind turbine tower is generally between 60 meters and 80 meters, the overall weight of the wind turbine cabin is about 60 tons to 90 tons, and the individual weight of large components such as gearboxes, generators, and blades is about 10 tons to 20 tons. Limited to the requirements of the height and weight to be transported, the crane used must have a lifting height of 80 meters and a corresponding lifting capacity. Therefore, the disassembly and installation tasks must be completed with the assistance of a large crane. On the one hand, the cost of the large crane itself is relatively high; on the other hand, due to the remote location of the wind power plant, it is very difficult to transport the large crane to the site, which increases the maintenance cycle of wind power generation and further increases the hoisting cost. Taking the maintenance of an ordinary wind farm as an example, in the maintenance of dismantling or replacing large parts, the cost of hoisting alone is as high as 400,000; high.

The reason for the high maintenance cost of wind power generation is that it is difficult to hoist at high altitude and the cost is relatively high; in addition, with the advancement of technology, the height of land and sea buildings or other artificial facilities continues to increase. Since the current lifting device is driven by hydraulic or electric power, And it is difficult to be independent from the corresponding facilities, and cannot meet the requirements for multi-angle, multi-directional, and flexible maintenance of these facilities. During maintenance, it also needs the assistance of large cranes for high-altitude hoisting to complete. There are also difficulties in high-altitude hoisting and high costs.

Referring to Fig. 2, the movable clamping plate 10 is fixed on one end of the clamping oil cylinder 12, and the other end of the six clamping oil cylinders 12 is fixed on the hole wall of the middle hole 1-1 of the upper platform 1, and the six movable clamping plates 10 The two are facing each other, evenly distributed, and can protrude toward the center of the middle hole 1-1. The 6 clamping cylinders fixed on the wall of the middle hole 1-1 and the movable clamping plate 10 form the clamping mechanism of the upper platform 1. . Similarly, the other ends of the other 6 clamping oil cylinders 12 are fixed on the wall of the middle hole 2-1 of the lower platform 2, and form the clamping mechanism of the lower platform 2 with the movable clamping plate.

The upper platform 1 and the lower platform 2 are connected by a telescopic oil cylinder 9, and the two ends of the telescopic oil cylinder 9 are respectively fixed with the upper platform 1 and the lower platform 2. As a telescopic mechanism between the upper platform 1 and the lower platform 2, the extension or retraction of the piston of the telescopic oil cylinder 9 can change the distance between the upper platform 1 and the lower platform 2. In this example, there are four telescopic oil cylinders 9, They are respectively located at the four corner positions between the upper platform 1 and the lower platform 2 to ensure the stability and reliability of the distance change between the upper platform 1 and the lower platform 2.

After the assembly is completed, the work of climbing up can be carried out.

The working process of the climbing device 100 climbing up is:

In the first step, when the pistons of the six clamping oil cylinders 12 on the lower platform 2 are extended at the same time, the six movable clamping plates 10 move to the center of the middle hole 2-1 together, thereby contacting the outer wall of the fan tower, and A corresponding force is applied to the outer wall of the fan tower to generate frictional force between the outer wall of the fan tower and the movable clamping plate 10, and the frictional force makes the lower platform 2 fixed on the outer wall of the fan tower. The clamping mechanism on the lower platform 2 is used as a lower fixing mechanism to fix the entire climbing and lifting system to the fan tower by fixing the lower platform 2 on the outer wall of the fan tower.

In the second step, the pistons of the four telescopic oil cylinders 9 are stretched out at the same time, so that the distance between the upper platform 1 and the lower platform 2 is increased. Since the lower platform 2 is fixed to the outer wall of the fan tower, the upper platform 1 will rise by a distance of a stroke.

In the third step, the piston of the clamping oil cylinder 12 of the upper platform 1 is extended at the same time, and the 6 movable clamping plates 10 on the upper platform 2 move to the center of the middle hole 1-1 together, so that the outer wall of the fan tower and the movable clamp A corresponding frictional force is generated between the holding plates 10, so that the upper platform 1 is fixed on the outer wall of the fan tower. Similarly, the clamping mechanism on the upper platform 1 is used as an upper fixing mechanism to fix the entire climbing and lifting system to the fan tower by fixing the upper platform 1 on the outer wall of the fan tower.

In the fourth step, the clamping oil cylinder 12 on the lower platform 2 is retracted, and the movable clamping plate 10 on the lower platform 2 is separated from the outer wall of the fan tower.

In the fifth step, the 9 pistons of the telescopic oil cylinder are retracted at the same time, so that the lower platform 2 is raised by one stroke. Then repeat the first process, through the multiple expansion and contraction of the telescopic oil cylinder 9, the height of the climbing and lifting device is continuously increased, and gradually climbs to the top of the wind turbine tower.

After the climbing and lifting system reaches the top of the wind turbine tower, the lifting device 200 starts to work. The slewing support at the top of the column 3 drives the boom 4 to rotate to the air above the wind turbine cabin under the drive of the hydraulic motor. The pulley mechanism 5 cooperates with the spreader 4 to remove the fault Lift the components; the boom 4 rotates again to the side away from the wind turbine tower. At this time, the counterweight 11 and the faulty component are respectively located on both sides of the column 3, which can play a role of balance and prevent the climbing and lifting system from deflecting. Start the climbing device, and gradually lower the climbing and lifting device to the ground through repeated steps to repair the faulty parts.
