Technical Field

[0001] The utility model relates to the technical field of wind power tower loading and unloading devices, and particularly relates to a hydraulic loading and unloading vehicle device for wind power towers. Background Technique

[0002] Wind energy is a clean, pollution-free and renewable energy source. Using wind energy for power generation has the characteristics of being pollution-free, renewable, and having mature technology, and the wind energy reserve is huge. Therefore, it has been increasingly valued by countries around the world. Wind power generation converts the kinetic energy of the wind into electrical energy. Existing wind turbines generally consist of a tower, a wind wheel, a generator, etc. When building a wind turbine, various parts need to be transported separately.

[0003] Existing wind power towers are generally composed of multiple sections for convenient transportation. Flanges are provided at their ends to connect the various sections of the tower, and at the same time, a stable interface is provided during transportation and installation. According to the current design status of wind power towers, the tower length ranges from 10 to 30 meters, and the maximum diameter is about 6m. The weight is very large. In some environments without fixed-rail overhead cranes, the loading and unloading of towers generally use mobile truck cranes for loading and unloading.

[0004] However, when using a mobile truck crane, generally a large standing space is required, the shift fee is relatively high, and a large number of workers are needed, which is not convenient for loading and unloading towers under the condition of no fixed track. To solve this technical problem, the utility model proposes a hydraulic loading and unloading vehicle device for wind power towers. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a hydraulic loading and unloading vehicle device for wind power towers, which can effectively solve the problems mentioned in the background technique.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] The hydraulic loading and unloading vehicle device for wind power towers includes two bases and a flange. A hydraulic cylinder is fixedly installed on the upper surface of each base. A support frame is arranged above the hydraulic cylinder. A high-strength bolt is installed on one side of the support frame. The support frame is fixedly connected to the flange through the high-strength bolt. A cross plate is fixedly connected to the side of the support frame. Two calibration mechanisms are respectively arranged at both ends of the cross plate. The two calibration mechanisms correspond to the positions of the two hydraulic cylinders.

[0008] Preferably, a plurality of first reinforcing rods are fixedly connected to the upper surface of the base. The end of the first reinforcing rod away from the base is fixedly connected to the hydraulic cylinder.

[0009] Preferably, a plurality of second reinforcing rods are fixedly connected to the upper and lower surfaces of the cross plate. The end of the second reinforcing rod away from the cross plate is fixedly connected to the support frame.

[0010] Preferably, four first lifting lugs are installed on the upper surface of the base, and two second lifting lugs are installed on the upper surface of the support frame.

[0011] Preferably, the calibration mechanism includes a fixed pipe. The upper surface of the fixed pipe is fixedly connected to the cross plate. The inside of the fixed pipe is hollow. A sliding rod is slidably connected to the inner wall of the cross plate, and a stopper is installed on the upper surface of the sliding rod.

[0012] Preferably, the lower end of the sliding rod is fixedly connected to a calibration block, and the outer surface of the calibration block is slidably connected to the fixed pipe.

[0013] Preferably, a convex block is installed on the upper surface of the telescopic end of the hydraulic cylinder. A groove is formed inside the calibration block, and the shape and size of the calibration block are adapted to the groove.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] In the utility model, by setting components such as a hydraulic cylinder and a support frame, during actual use of the device, first fix the support frame to the flange through high-strength bolts, place the two hydraulic cylinders on both sides of the support frame, drive the support frame to lift through the calibration device, lift the wind turbine tower upward, and then cooperate with a truck to complete the loading and unloading of goods, achieving the effect of facilitating loading and unloading. It does not require a large standing space, reduces costs, and is suitable for the loading and unloading of tower frames under the condition of no fixed track, thus solving the problems that existing mobile truck cranes generally require a large standing space, have a high shift fee, require a large number of workers, and are not convenient for the loading and unloading of tower frames under the condition of no fixed track.

[0016] In the utility model, by setting components such as a calibration mechanism, under the action of gravity, the sliding rod slides downward, so that the calibration block slides to the lower part of the top of the hydraulic cylinder, adjusts the position of the hydraulic cylinder, and inserts the convex block on the hydraulic cylinder into the inside of the groove, thereby realizing the calibration of the hydraulic cylinder, making the top of the hydraulic cylinder and the fixed pipe on the same line, preventing the position deviation from being found and adjusted after the hydraulic cylinder starts, which is too troublesome, and achieving the effect of increasing convenience. The support frame and the hydraulic cylinder are detachable and can be installed separately. When not in use and during transportation, the smaller single body occupies a small volume, which is convenient for storage and transportation, achieving the effect of facilitating storage.

Specific embodiments

[0023] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] As Figures 1-5 shown, the hydraulic loading and unloading vehicle device for a wind power tower includes two bases 1 and a flange 4. A hydraulic cylinder 2 is fixedly installed on the upper surface of each base 1. A support frame 3 is arranged above the hydraulic cylinder 2. A high-strength bolt 5 is installed on one side of the support frame 3. The support frame 3 is fixedly connected to the flange 4 through the high-strength bolt 5. A cross plate 6 is fixedly connected to the side of the support frame 3. Two calibration mechanisms 7 are respectively arranged at both ends of the cross plate 6. The two calibration mechanisms 7 correspond to the positions of the two hydraulic cylinders 2. The support frame 3 and the cross plate 6 are both composed of high-strength alloys and are integrally formed. The number of high-strength bolts 5 is four, which can fix the support frame 3 and the flange 4 together. The flange 4 is connected to the end of the wind power tower.

[0025] A plurality of first reinforcing rods 8 are fixedly connected to the upper surface of the base 1. One end of the first reinforcing rod 8 far from the base 1 is fixedly connected to the hydraulic cylinder 2. The calibration mechanism 7 includes a fixed pipe 701. The upper surface of the fixed pipe 701 is fixedly connected to the cross plate 6. The inside of the fixed pipe 701 is hollow. A sliding rod 702 is slidably connected to the inner wall of the cross plate 6. A stop block 704 is installed on the upper surface of the sliding rod 702. The stop block 704 cooperates with the cross plate 6 to limit the sliding rod 702 to prevent the sliding rod 702 from detaching from the cross plate 6 and to limit the downward sliding amplitude of the sliding rod 702. The lower end of the sliding rod 702 is fixedly connected to a calibration block 703. The outer surface of the calibration block 703 is slidably connected to the fixed pipe 701. A convex block 705 is installed on the upper surface of the telescopic end of the hydraulic cylinder 2. A groove 706 is formed inside the calibration block 703. The shape and size of the calibration block 703 are adapted to the groove 706. When in use, first move the sliding rod 702 downward. The cross plate 6 restricts the sliding rod 702 to prevent the sliding rod 702 from tilting, so as to ensure that the sliding rod 702 is always located at the center position of the fixed pipe 701. Adjust the position of the hydraulic cylinder 2 so that the convex block 705 on the upper surface of the hydraulic cylinder 2 is inserted into the groove 706, so that the hydraulic cylinder 2 and the sliding rod 702 are kept in a straight line. After calibrating the position of the hydraulic cylinder 2, then apply pressure to prevent the hydraulic cylinder 2 from not being inserted into the fixed pipe 701 after pressurization, resulting in moving the hydraulic cylinder 2 again, causing trouble.

[0026] By providing the first reinforcing rods 8 to increase the stability of the hydraulic cylinder 2 and prevent the hydraulic cylinder 2 from tilting during use, etc., the hydraulic cylinder 2 is firmly fixed to the base 1. A plurality of second reinforcing rods 9 are fixedly connected to both the upper surface and the lower surface of the cross plate 6. One end of the second reinforcing rod 9 far from the cross plate 6 is fixedly connected to the support frame 3. Both ends of the second reinforcing rod 9 are welded to the support frame 3 and the cross plate 6 respectively to increase the firmness between the support frame 3 and the cross plate 6 and prevent cracking, etc., improving the use stability. Four first lifting lugs 10 are installed on the upper surface of the base 1. Two second lifting lugs 11 are installed on the upper surface of the support frame 3. The base 1 is convenient to move through the first lifting lugs 10 to ensure the positioning of the device. Similarly, the support frame 3 and the flange 4 are convenient to install through the second lifting lugs 11.

[0027] It should be noted that in actual use of the device, first fix the support frame 3 to the flange 4 through high-strength bolts 5, place the two hydraulic cylinders 2 on both sides of the support frame 3. Under the action of gravity, the sliding rod 702 slides downward, so that the calibration block 703 slides to the lower part of the top of the hydraulic cylinder 2. Adjust the position of the hydraulic cylinder 2 so that the convex block 705 on the hydraulic cylinder 2 is inserted into the groove 706, thereby realizing the calibration of the hydraulic cylinder 2, making the top of the hydraulic cylinder 2 and the fixed pipe 701 in a straight line, preventing the position deviation of the hydraulic cylinder 2 from being found after it starts and then being adjusted, which is too troublesome, achieving the effect of increasing convenience.

[0028] The support frame 3 is detachable from the hydraulic cylinder 2 and can be installed separately. When not in use or during transportation, the smaller individual units occupy less volume, facilitating storage and transportation, thus achieving the effect of easy storage.

[0029] After the hydraulic cylinder 2 presses against the calibration block 703, it enters the interior of the fixed tube 701. By squeezing the cross plate 6 through the calibration block 703, the support frame 3 is driven to lift. During use, two such devices need to be set, respectively located at both ends of the wind power tower to lift together, so that the wind power tower no longer contacts the bottom of the cargo box upwards. The truck drives away between the two hydraulic cylinders 2, and then the wind power tower is placed on the ground, thus completing the unloading of the goods. The loading process is the same. First, the wind power tower is lifted, and the truck reverses between the two hydraulic cylinders 2 to load the goods, achieving the effect of easy loading and unloading. It does not require a large standing space, reduces costs, and is suitable for the loading and unloading of tower frames under conditions without fixed tracks.
