At present, domestic and foreign wind power engineering projects are being vigorously constructed to promote the development of wind power. The domestic transportation of wind power blades is mostly based on the existing Shengtong trailers by welding some auxiliary parts to fix the blades and then buy the current blades. This method of transportation requires low trailer speed, good road conditions, poor vibration damping and passing performance, and low efficiency and feasibility.
3 Line 6 Axle Windmill Blade Trailer with Adapter
Overall design of TITAN VEHICLE
The vane transporter is composed of tractor, cargo platform, axle, suspension system, support device, steering system, braking system and electrical system.
The overall dimensions of the vane transporter are 28000 mm x 2700 mm x 1250mm; the drive form is 4x2; the axle is 3 lines and 6 bridges. The tires are 8.25R15 steel wire tires: hydraulic cylinder lifting suspension system; lifting range greater than 400 mm; hydraulic system working pressure 16 MPa; cargo platform uses cylinder steering. The maximum turning angle is 45°; the cargo platform is a modular cargo platform. Cargo platform can be vertical
Splicing combination; the semi-trailer adopts a dual-pipeline air-cut braking system, and is equipped with a hand brake device, which can be parked independently through a supporting device.

The cargo platform is composed of three parts: the auxiliary cargo platform, the intermediate cargo platform and the rear cargo platform. Each part of the cargo platform can be combined and spliced with fork joints. The entire cargo platform is a frame structure, and the cargo platform is welded by beams and longitudinal beams. The longitudinal beam adopts the I-shaped structure. The I-shaped structure has the characteristics of high strength and simple technology: the cross beam adopts square steel and channel steel: seamless steel pipes are welded under the lower wing plate of the main longitudinal beam, and the seamless steel pipes are connected The purpose of welding seamless steel pipes is to increase the rigidity of the cargo platform. Reduce the amplitude of the up and down vibration of the cargo platform during driving.
Since the cargo platform is long, the turning radius of its driving is large, and the passing performance is not good. Therefore, in the no-load state, the front cargo platform and the rear cargo platform are directly cross-connected to improve the passage of the whole vehicle.
Hydraulic suspension system
The lifting of the entire cargo platform is realized by hydraulic suspension. The hydraulic suspension is composed of a cantilever, a swing arm and a suspension cylinder. The cantilever and the swing arm and the suspension cylinder are connected by articulation, and the swing arm and the suspension cylinder are connected by a ball joint. When the cargo platform is lifted, the suspension cylinder is extended under the action of hydraulic pressure, the angle between the cantilever and the swing arm increases, and the cargo platform is raised to the highest position.
When the cargo platform is lowered, the suspension cylinder is suspended under the action of the cargo platform and its own weight The size is reduced, the cargo platform is lowered to the lowest, and its lifting stroke is 400 mm. In addition to providing the lifting and leveling functions of the whole vehicle, each suspension is more importantly the expansion and contraction compensation function of the hydraulic cylinder to ensure the uniform load of the wheels during operation, avoid slipping, to adapt to uneven road conditions and maintain safe operation reliable.

The steering system is the key to the entire design. It is related to the safety of the vehicle and the stable operation. The steering system of the fan-blade transporter is composed of a central bogie, a tie rod, a longitudinal tie rod, a transverse steering arm, a longitudinal steering arm and a steering cylinder. The steering system of the fan-blade transporter adopts mechanical-hydraulic combined steering, that is, the steering handle of the hydraulic valve block is manually operated to make the hydraulic oil enter the steering cylinder. Control the expansion and contraction of the piston rod of the oil cylinder, and the push and pull force of the piston rod of the oil cylinder acts on the central bogie, the tie rod, the transverse steering arm, the longitudinal steering arm, and the longitudinal tie rod in turn to realize the steering of the whole vehicle.
The above content introduces the overall structure of the vane transporter and the characteristics of its components. The vane transporter has been put into use in production and life.

What is the general production of wind blade storage and transportation-windmill blade trailer
In the existing technology, when replacing the storage tooling, it is necessary to locate the position on the ground first, and then hoist the blade into the tooling after the pre-laying is completed. The process is very complicated and the workload is also large. At the same time, the tooling is stored in advance. There is uncertainty in the laying position, and errors will occur every time it is laid, resulting in the mismatch between the shape of the blade and the blade where the tooling is stored, and it is easy to cause damage to the blade. After the wind blade is drawn, the blade needs to be lifted out of the mold and placed on the blade transfer vehicle, and then the blades need to be transferred to the workshops for repairing, polishing, drilling, painting, etc. for post-processing. After completion, the storage tools need to be replaced to put the blades in. Inventory storage and replacement of storage tooling poses certain safety hazards and risks of damaging blades. At present, the blades need to be replaced with tooling, which brings safety hazards, and the blades need to be lifted during replacement, which is very easy to damage the blades and bring trouble to later repairs.
In order to solve the problems in the prior art, the utility model provides a general-purpose tooling for storage and transfer of wind blades. The tooling ensures that during the blade transfer, storage, and process, the assembly and disassembly of the tooling ensure that the blades cannot be lifted or replaced. The purpose of tooling.
Process of wind blade design
In the process of blade design. The total can be divided into two stages. The first is the aerodynamic design stage, and the second is the structural design stage of the wind turbine. There is a general goal in all design processes: the blades designed have the best shape to achieve annual power generation. The biggest. When designing the structure, we have to choose the structure of the blade and the blade material we want to use. The analysis should consider whether the stability, rigidity and strength of the blade can reach the target in the actual work.

The following procedures are generally followed when designing the wind blades of windmill blade trailer:
First, the initial parameters of the wind turbine must be set. Then we will analyze the aerodynamic characteristics of the blade and the static structure of the blade. When these two analyses are completed, the parameter results obtained from the analysis should be fed back. Compare with the initial parameters previously set. It is found that there are unreasonable places to modify the parameter content. In the end, a satisfactory design can be obtained. But in the actual design process, the well is not absolutely carried out in accordance with this design process. For example, when designing the blade structure. Structural design is not entirely subordinate. Sometimes when starting to discuss the overall structure of the blade. Need to think about the content of the plan from the perspective of structural design. Finally put forward the amendments to the pneumatic scheme. And sometimes due to structural design reasons, it is necessary to change the aerodynamic shape to finally obtain a blade with reasonable structural performance. Therefore, the overall design of the blade is often the result of a reasonable balance of various performance relationships.
