Abstract
Description
Technical Field
[0001] The utility model relates to a chiller structure, and specifically discloses a chiller for casting a planetary frame of a wind power plant. Background Art
[0002] As a clean and renewable energy source, wind energy is increasingly valued by countries around the world. With the saturation of the onshore wind power market, the rise of offshore wind power is inevitable; thus, the development of planetary racks for large-power wind turbines is increasing, which is also a challenge to the existing production conditions of various foundries. How to use existing equipment and produce planetary racks for large-power wind turbines at a lower cost is also a difficult problem that casting manufacturers need to overcome.
[0003] At present, when casting wind turbine planetary frames, dozens of chillers need to be placed on the long axis of the wind turbine planetary frames. It is difficult for workers to place the chillers and the operation time is long. There are many waste strips formed between the two chillers, and more molten metal is consumed during pouring, which increases the casting cost. After the casting is formed, there are many waste strips formed between the two adjacent chillers. It takes a long time to grind these waste strips, and the production efficiency is low. Summary of the invention
[0004] The utility model aims to overcome the shortcomings of the prior art and provide a chiller for wind power planetary frame casting, which is easy for workers to place the chiller, can reduce casting costs, improve production efficiency and improve casting quality.
[0005] According to the technical solution provided by the utility model, the chiller for casting a planetary frame of a wind power type comprises a chiller body, a lifting lug and a reinforcing rib;
[0006] The cold iron body is a plate with a fan-shaped cross section, a lifting lug is fixed on the upper end surface of the cold iron body, and reinforcing ribs arranged in a criss-cross pattern are fixed on the outer circular surface of the cold iron body. The inner circular surface shape of the cold iron body matches the outer circular surface shape of the long axis of the wind power planetary frame to be cast, and the center angle corresponding to the fan-shaped cross section of the cold iron body is 60-90°.
[0007] Preferably, the reinforcing rib has a width of 30-50 mm and a height of 30-50 mm.
[0008] Preferably, the outer circle of the lower end portion of the cold iron body is a cone that converges toward its axial direction.
[0009] After the utility model is used, the difficulty of placing the chiller by the worker can be reduced and the operation time can be shortened. Less molten metal is consumed during pouring, the casting cost is reduced, the time for grinding the waste strips is greatly shortened, and the production efficiency is greatly improved. The chiller of the utility model has high strength and long service life, can strengthen the firmness of the combination between the outer molds, prevent the chiller from shifting during pouring, and improve the quality of the casting.

[0013] The utility model is further described below in conjunction with specific embodiments.
[0014] The utility model is a chiller for casting a planetary carrier of a wind power plant, such as Figure 1-3 As shown, it includes a chill body 1, a lifting lug 2 and a reinforcing rib 3;
[0015] The cold iron body 1 is a plate body with a fan-shaped cross section, a lifting ear 2 is fixed on the upper end surface of the cold iron body 1, and reinforcing ribs 3 arranged in a criss-cross pattern are fixed on the outer circular surface of the cold iron body 1. The inner circular surface shape of the cold iron body 1 matches the outer circular surface shape of the long axis of the wind power planetary frame to be cast, and the center angle corresponding to the fan-shaped cross section of the cold iron body 1 is 60-90°.
[0016] The reinforcing rib 3 has a width of 30-50 mm and a height of 30-50 mm.
[0017] When placing, the chiller of the utility model can be easily hoisted to the required position by the lifting lug 2. When the chiller of the utility model is used to cast a wind power planetary frame, only a few chillers need to be placed on the long axis of the wind power planetary frame. The workers have little difficulty in placing the chillers and the operation time is short. The number of waste strips formed between the two chillers is small, and less molten metal is consumed during pouring, which reduces the casting cost. After the casting is formed, the number of waste strips formed between the two adjacent chillers is small, and it takes less time to grind these waste strips, which greatly improves the production efficiency.
[0018] The outer circumferential surface of the chill body 1 is fixed with reinforcing ribs 3 arranged in a crisscross pattern, which can not only increase the strength of the chill and extend its service life, but also strengthen the bonding strength between the chill and the outer mold, prevent the chill from shifting during pouring, and improve the quality of the casting.
[0019] The outer circle of the lower end of the cold iron body 1 is a conical surface 1.1 that converges toward its axis, which is convenient for workers to compact when placing sand.
[0020] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to examples, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
