Description

a support system

technical field

The utility model relates to the field of wind power generation, in particular to a support system for maintaining blades and towers of wind power generation equipment and supporting a hanging basket for high-altitude operations on the tower.

Background technique

At present, the blades of wind power generation equipment and the outer wall of the tower tube are exposed to the outside for a long time, and are easily eroded by lightning strikes, salt spray, sand and dust, etc., resulting in sand holes in the blades and paint peeling on the outer wall of the tower tube. The trachoma in the blade not only increases the rotational resistance of the blade, reduces its speed, and affects the power generation efficiency, but also may store water in the trachoma, which increases the surface humidity of the blade and reduces the lightning protection index. In addition, in order to maximize the use of wind energy to generate electricity, the fan blade is a curved and inclined surface with a radian to maximize the rotational speed. Therefore, it is very difficult to overhaul it. Generally, the traditional maintenance methods are spiders and cranes, but this is not only dangerous, but also inconvenient for the operation process and the work of the staff; there are also high-altitude work hanging baskets for maintenance, but it is not convenient to approach the blades, and at the same time, it is not very convenient. Stability brings difficulties to maintenance work.

Wherein, the system also includes a right-angle fence body and hanger guardrails located on both sides of the right-angle fence body, the fence body, right-angle fence body and hanger guardrail are connected together by bolts, and the hand winch is fixed on the outside of the right-angle fence body On the guardrail; the hanger guardrail is equipped with a support rod bracket.

Wherein, the support assembly includes a beam bracket and two support rods, and the two support rods penetrate into the support wheels of the support rod bracket from the outside; the beam bracket and the two support rods are fixed by bolts.

Wherein, the ends of the two support rods are provided with guide wheels or perforated bolts.

Wherein, a corner tugboat assembly is installed on the outer guardrail of the right-angle fence body.

Wherein, one end of the two support rods is provided with a guide wheel.

Wherein, one end of the steel wire rope is fixed on the support bar without a guide wheel among the two support bars, and then passes through the corner tug wheel assembly and the guide wheel in turn, and is fixed with the manual winch.

Wherein, one end of the steel wire rope is fixed on the support rod without a guide wheel among the two support rods through a perforated bolt.

The technical solution of the utility model has the following advantages: it can adapt to the slope surface of the blade to repair the blade, and at the same time, the stability of the basket in the air is improved, the structure is simple, the operation is simple, and the safety of the staff is improved.

Detailed ways

Below in conjunction with accompanying drawing and embodiment; The specific embodiment of the utility model is further described. The following examples are only used to illustrate the technical solution of the utility model more clearly, but not to limit the protection scope of the utility model.

In order to solve the problem that the blades are difficult to overhaul, the utility model adopts a telescopic support frame to solve this difficult problem. The telescopic support frame is mainly composed of a support component and a traction component. The head of the beam bracket in the support assembly has inclined feet, and is equipped with inclined nylon runners; the inclination of the head of the beam bracket can be used to adapt to different peripheral diameters of the tower. Because the tower is tapered upwards, the diameter of the lower part is large, and the diameter of the upper part is small, and the traction component mainly makes the supporting component extend outwards by relying on the outer wall of the tower, and adjusts the distance between the fence and the outer wall of the tower, so as to adapt to the maintenance of the blades .

As shown in Figure 1, connect the fence body 1, the right-angle fence body 10, the fence body 9 and the hanger guardrail 3 with bolts; Component 5 is installed on the outer guardrail of right angle fence body 10 (position as shown in Figure 1), and two support rods 6,8 are penetrated in the support wheel of support rod support 2 from the outside. After the two support rods are worn, the guide wheels or piercing bolts at their ends are reinstalled. Fix the hand winch 4 on the outer guardrail of the right-angle fence body 10; penetrate the traction wire rope 13 (as shown in Figure 2), fix one end of the traction wire rope on the support rod 8 with the perforated bolt 11, and pass the corner tugboat assembly 5 and the guide wheel 12 of support rod 6 are fixed with manual winch 4 behind; Crossbeam support 7 and two support rods 6,8 are fixed with bolts at last.

Working process: In Fig. 2, since one end of the traction wire rope 13 is fixed to the support rod, when the hand winch 4 is turned, the traction wire rope 13 will be tightened, and the total length of the traction wire rope will be gradually shortened, and the corner tug wheel assembly 5 of the traction wire rope will It is fixed on the fence so that the support rods 6 and 8 are extended outwards, and finally the whole fence can be extended outward; when the manual winch 4 is turned in the opposite direction, the support rods 6 and 8 will be subjected to two forces between the fence body and the tower wall. In general, the length of the traction wire rope can be driven by the manual winch 4 to adjust the distance relationship between the fence body and the tower to achieve the distance required by the staff.

Figure 3 is a picture of the actual application of the support assembly and the traction assembly. It can be seen from the figure that the wire rope drives the fence body 1 through the hoist, and moves up and down through the support of the support assembly on the outer wall of the tower tube. When the fence body moves below the fan blades 13, the distance between the fence body and the outer wall of the tower tube 14 is adjusted by the traction assembly, so that the middle part of the fence body passes through the blades for maintenance.

The above is only a preferred embodiment of the utility model; it should be pointed out; for those of ordinary skill in the art; without departing from the technical principle of the utility model; several improvements and modifications can also be made; these improvements And retouching should also be regarded as the protection scope of the present utility model.
