[0002] In the manufacturing of wind turbine towers, special transport vehicles are used for in-plant transportation of towers. Due to production needs, towers are often stored on concave supports on the roadside. When transferring, the tower needs to be transported between the transport vehicle and the roadside support. If a truck crane is used for transport, the cost is extremely high. In order to reduce costs, technicians designed a jacking method. The tower is lifted up with a jack and a movable bracket, so that the tower is higher than the transport vehicle and the bracket, and the transport vehicle and the bracket are shifted to achieve the transport of the tower. Since the jack is manually operated, the lifting speed is slow, the work efficiency is very low, and the entire operation process takes a long time. 2-3 sections of the tower can be transported in one day, which is not conducive to production flow and construction period control. In addition, the work intensity of personnel is high, and they are located under the tower during operation, which poses certain safety risks. Summary of the invention

DETAILED DESCRIPTION

[0016] The following is a further detailed description of the specific implementation of the utility model in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the utility model.

[0017] like Figures 1 to 5 As shown, the utility model includes more than two support components, and the support components include rollers 1, a support platform 2, lifting legs 3 and an adjustment mechanism. The middle part of the support platform 2 is provided with an inwardly concave limit groove, and the two sides of the limit groove are also provided with adjustment mechanisms. The lifting legs 3 are provided below the four corners of the support platform 2, and the sides of the lifting legs 3 are provided with rollers 1. When the inverting vehicle arrives at the storage point, several support components are placed under the tower on the inverting vehicle, and then the lifting legs 3 are lifted, the rollers 1 are suspended in the air, and the support platform lifts the tower. The tower support on the inverting vehicle can be pulled out from under the tower, and then the bracket is placed under the tower, the lifting legs 3 are retracted, and then the tower falls onto the bracket to complete the unloading. Afterwards, the lifting legs 3 continue to retract, the rollers 1 touch the ground, the tower is separated from the support platform 2, and finally the support components can be withdrawn.

[0018] Specifically, in order to realize the lifting and lowering of the lifting legs 3, the lifting legs 3 include a lifting cylinder 4, an upper cylinder 5 and a lower cylinder 6. The bottom of the lower cylinder 6 is provided with a foot. The top of the upper cylinder 5 is fixedly connected to the bottom surface of the support platform 2. The bottom of the upper cylinder 5 is sleeved outside the lower cylinder 6. The cylinder barrel and cylinder rod of the lifting cylinder 4 are respectively connected to the bottom end of the upper cylinder 5 and the top end of the lower cylinder 6. In order to ensure the stability of the lifting and lowering of the support platform 2, the lifting cylinders 4 are all supplied with oil by a same hydraulic oil station 7. The extension and retraction of the lifting cylinder 4 can control the height of the lifting legs 3, thereby achieving stable lifting and lowering of the support platform 2.

[0019] The adjusting mechanism includes two symmetrically arranged baffles 8, a lifting column 9, a lifting rod 10 and a supporting lever 11. The supporting lever 11 is located on both sides of the supporting platform 2 and is arranged on both sides of the limiting groove. Both ends of the supporting lever 11 are connected to the supporting platform through bearings. An adjusting screw hole is provided on the supporting lever 11. The inner side of the baffle 8 is hinged to the supporting platform outside the limiting groove, the outer side of the baffle 8 is hinged to the top of the supporting lever 11, the top of the lifting column 9 is hinged to the outer side of the baffle 8, the bottom of the lifting column 9 is provided with a cylindrical groove 13, the top of the lifting rod 10 extends into the groove 13, the bottom of the lifting rod 10 is provided with an external thread, the external thread matches the thread of the adjusting screw hole, the bottom end of the lifting rod 10 passes through the adjusting screw hole on the supporting lever 11, and the bottom end of the lifting rod is connected with an adjusting handle 12. By rotating the adjustment handle 12, the distance between the baffle 8 and the support rod 11 can be controlled, so that the two baffles 8 can be opened and closed, and the tower can be hugged or opened and closed on one side to fine-tune the axis of the tower in the limiting groove.

[0020] In order to ensure the stability of the connection between the lifting rod 10 and the lifting column 9, a limit plate 14 is provided at the top of the lifting rod 10. The limit plate 14 is loosely matched with the groove 13. A retaining ring 15 is provided at the lower edge of the groove 13. The size of the limit plate 14 is larger than the inner edge diameter of the retaining ring 15.

[0021] It takes about 3.5 hours to lift a section of the tower manually, but the utility model only takes 0.7 hours, which increases the work efficiency by about 5 times. It eliminates the process of workers manually operating the jack, which can save about 52,000 yuan in labor costs each year and reduce the risk of personnel operation.

[0022] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
