Detailed Description
The following detailed description of the invention is, therefore, not to be taken in a limiting sense, but is made merely by way of example. While the advantages of the invention will become apparent and readily appreciated by reference to the following description.
As can be seen with reference to the accompanying drawings: the wind driven generator blade transportation semitrailer comprises a tractor 1 and a semitrailer 9, wherein the semitrailer 9 comprises a gooseneck 2, a front barrel 3, a middle barrel 4, a rear barrel 5, a hydraulic axis vehicle module 6 and a sliding tail frame 7, a traction pin 24 at the front end of the gooseneck 2 is connected with the tractor 1 through a traction saddle 11, a supporting leg 21 is arranged at the rear end of the gooseneck 2, the lower part of the rear end of the gooseneck 2 is hinged with the front barrel 3, and a first connecting cross beam 22 is arranged at the upper part of the rear end of the gooseneck 2 (shown in figures 1 and 4);
The front end of the front cylinder body 3 comprises a second connecting beam 31, the second connecting beam 31 is connected with the first connecting beam 22 through a connecting bolt 23, and a plurality of gaskets 231 are detachably arranged on the connecting bolt 23; the front cylinder 3 has first bearing platforms 32 on two sides of the front end, and a plurality of front cylinder connecting hole seats 33 (as shown in fig. 4, 7 and 8) are arranged on the front cylinder 3 at intervals;
The lower part of the rear end of the gooseneck 2 and the lower part of the front end of the front barrel 3 are respectively provided with a first hinge socket 84, and the two first hinge sockets 84 are hinged through a pin shaft;
the front end of the middle cylinder 4 is connected with the front cylinder 3 through a front cylinder connecting hole seat 33, and a plurality of middle cylinder connecting hole seats 41 (shown in fig. 9 and 10) are arranged on the middle cylinder 4 at intervals;
The front end of the rear cylinder 5 is connected with the middle cylinder 4 through a middle cylinder connecting hole seat 41, a plurality of rear cylinder connecting hole seats 51 are arranged on the rear cylinder 5 at intervals, and a third connecting cross beam 52 (shown in fig. 11 and 12) is arranged at the upper part of the rear end of the rear cylinder 5;
The lower part of the front end of the hydraulic axis vehicle module 6 is hinged with the lower part of the rear end of the rear cylinder 5, and the upper part of the front end of the hydraulic axis vehicle module 6 is connected with a third connecting beam 52; the hydraulic axis car module 6 is a standard mature product, the height of the hydraulic axis car module can be raised and lowered, and the wheel axle can be turned (as shown in fig. 1,2 and 3).
The sliding tailstock 7 is located above the hydraulic axis car module 6, the front end of the sliding tailstock 7 is hinged with the rear cylinder connecting hole seat 51, and the rear end is provided with a second bearing platform 71 (as shown in fig. 13 and 14); when the front cylinder 3, the middle cylinder 4 and the rear cylinder 5 extend out completely and the sliding tailstock 7 is suspended to the maximum, the distance between two bearing points on the semitrailer 9 can reach 60 meters (as shown in figure 1); when the front cylinder 3, the middle cylinder 4 and the rear cylinder 5 are fully retracted and the rear end of the sliding tailstock 7 slides to be flush with the rear end of the hydraulic axis car module 7 (namely, when the suspension is zero), the length of the whole semitrailer 9 is 25 meters, so that the loading of large blades like 5 megawatts can be ensured, and meanwhile, the rear end of the semitrailer is easy to return after the transportation work is finished (as shown in figure 2).
The first bearing platform 32 has a first bearing point 321 of the blade 83, and the second bearing platform 71 has a second bearing point 711 of the blade 83; the first bearing point 321 is at the root of the blade 83, the root of the blade 83 being cylindrical, the maximum transport height often being dependent on it, while the second bearing point 711 is generally at two thirds of the length from the root of the blade 83, where the blade 83 has been very flat in cross-section, so that a relatively high support is necessary to support it during transport. This determines that the vanes 83 do not touch the sliding tailstock 7, although the sliding tailstock 7 is placed on the hydraulic axis car module 6; compared with the hinged tail frame, the sliding tail frame 7 has smaller force born by the connecting pin, and the height of the carrying surface of the sliding tail frame 7 can be higher, so that the sliding tail frame 7 can bear larger load, the suspension length can be longer, and the suspension length can be changed conveniently. And is therefore more suitable for large blade transport (as shown in figure 1).
The telescopic connection between the cylinders of the invention is realized by connecting the middle cylinder 4 with different front cylinder connecting hole seats 33, hinging the rear cylinder 5 with different middle cylinder connecting hole seats 41 and sliding tailstock 7 with different rear cylinder connecting hole seats 51, and the semitrailers 9 with different lengths can be spliced to meet the transportation needs of blades with different lengths.
The number of the middle cylinders 4 is plural (as shown in fig. 1).
The front ends of the middle cylinder body 4 and the rear cylinder body 5 are respectively provided with a reinforcing ring 81, two first pulleys 811 are arranged on the upper part of the reinforcing ring 81, and two first side pulleys 812 are arranged on two sides of the reinforcing ring 81 (as shown in fig. 9, 10, 11 and 12); the rear ends of the front cylinder body 3 and the middle cylinder body 4 are respectively provided with a connecting plate 82, two second pulleys 821 are arranged at the lower part of the connecting plate 82, and second side pulleys 822 are arranged at two sides of the connecting plate 82 (shown in fig. 7, 8 and 9).
The sliding type tail frame 7 is provided with a plurality of pulleys 72, and the middle part of the sliding type tail frame 7 is provided with a lifting screw rod 73; pulley 72 makes telescoping more labor-saving; the lifting screw 73 can raise or lower the height of the second carrying platform 71 from the ground, so that the tip of the transported blade 83 is at a proper height from the ground (as shown in fig. 13 and 14).
In actual use, the rotation angle of the gooseneck 2, namely the height of the traction pin 24 from the ground, namely the height of the first half of the invention, is changed by increasing or decreasing the gaskets 231; in normal operation of the invention, a gasket 231 with a certain thickness is added between the first connecting beam 22 and the second connecting beam 31, so that the height of the front half part of the semi-trailer 9 at a separation mode is a normal value; when the invention passes through the place with the height limitation, the gasket 231 between the first connecting beam 22 and the second connecting beam 31 is taken out, the height of the front half part of the semitrailer 9 is separately reduced, and the height of the hydraulic axis vehicle module 6 is also reduced, so that the whole height of the semitrailer 9 is reduced, and the semitrailer can pass through the height-limited zone; the gooseneck 2 with the height adjusted by adding or reducing the gaskets 231 has the greatest advantages of reliability, simple structure and very low manufacturing cost, and is very suitable for occasions without frequent height adjustment; in addition to the support leg 21 on the gooseneck 2 for supporting the semi-trailer 9 after the separation of the tractor 1 from the semi-trailer 9, the addition or subtraction of shims 231 is also accomplished by this.
Other non-illustrated parts are known in the art.
