Carrying and storing method of wind tower

Abstract

The invention discloses a carrying and storing method of a wind tower, comprising the following steps of: preparing a platform lorry outside a workshop as a load bearing device, selecting the platform lorry as single lorry load bearing or parallel lorry load bearing according to the length of a parallel tower section, lifting the tower section and moving to the upper side of a vehicle or moving the platform lorry transversely to enter the lower side, namely a rolling wheel frame, of a tower cylinder, by using a crane, supporting the tower cylinder via movable rolling wheel support mechanisms,controlling the lifting height of an oil cylinder, enabling the distance between a lowest point of the tower cylinder and a table-board of a vehicle frame at 80-100 mm, sending an instruction via a program control centre, enabling the locking force of the movable rolling wheel support mechanisms to keep consistent, driving the platform lorry to an appointed area where the tower cylinder is piled,by a worker, lifting the tower cylinder and falling on a fixed support table frame in the appointed area by using the crane or controlling the movable rolling wheel support mechanisms of the platformlorry via the program control centre, enabling the tower cylinder to fall on the fixed support table frame in the appointed area, and finally moving the platform lorry out transversely. The carrying and storing method disclosed by the invention has the advantages of saving the cost fee, improving the working efficiency and reducing the resource consumption.

Description

technical field [0001] The invention relates to a transport and storage method for a wind tower. Background technique [0002] The transportation and storage of cylinder towers are generally hoisted by 50t, 80t or 100t gantry cranes outside the production line, transported horizontally to the designated area, and then stored by gantry cranes or need to ask foreign auto crane companies to provide car cranes for unloading. Disadvantages such as high cost, high operating energy consumption, and large site limitations, and the operation of the gantry crane needs to lay track, which requires a large investment. The operation of the gantry crane consumes about 200 degrees of electricity per hour, and the energy consumption is high; the tower section can only be within the driving range For transshipment, the site is limited, and when the gantry crane has a loading task in the target area of ​​the gantry crane, the transfer of the tower section must be stagnant, which directly affe...

Problems solved by technology

[0002] The transportation and storage of cylinder towers are generally hoisted by 50t, 80t or 100t gantry cranes outside the production line, transported horizontally to the designated area, and then stored by gantry cranes or need to ask foreign auto crane companies to provide car cranes for unloading. Disadvantages such as high cost, high operating energy consumption, and large site limitations, and the operation of the gantry crane needs to lay track, which requires a large investment. The operation of the gantry crane consumes about 200 degrees of electricity per hour, and the energy consumption is high; the tower section can only be within the driving range For transshipment, the site is limited, and when the gantry crane has a loading task in the target area of ​​the gantry crane, the transfer of the tower section must be stagnant, which directly affects production efficiency; the use of truck cranes has the disadvantages of high cost and slow operation. Two truck cranes operate at both ends of the tower at the same time, and the equipment investment is relatively high. During the operation, the truck crane operation area must be reserved on the site, which reduces the utilization rate of the yard, and the operation coverage area is small. Several wind tower towers are operated by the truck crane After a certain period, it is necessary to stop the operation, retract the boom, move the position, reposition, and then prepare for the start of work. The operation efficiency is low. Therefore, no matter whether the gantry crane or the truck crane is used to unload the truck, it is necessary to be equipped with personnel who pick and hang the hook. personal safety hazards
