Description

Technical Field

[0001] The utility model belongs to the technical field of wind power equipment production, and particularly relates to a special supporting frame for zinc spraying at a transition section of a wind tower. Background Art

[0002] Wind energy is a renewable clean energy with a large reserve. At present, wind turbines tend to be high-power. As the diameter of the impeller increases, the load generated by the wind also increases, making the diameter of the tower larger and larger. In the prior art, the tower is fixed on the concrete foundation through a transition section. The transition section is usually cylindrical with a flange at the bottom, and its weight is about 15 tons.

[0003] For example, the patent with application number CN200820233833.2 discloses a hybrid tower of a wind turbine generator set, which includes a reinforced concrete cylinder with a bottom section, a steel tower and a filter section for connecting the reinforced concrete cylinder and the steel tower. The reinforced concrete cylinder is directly cast on the foundation of the wind turbine generator set, the top of the transition section and the bottom end of the steel tower are fixedly connected by a flange and bolts, the bottom end of the transition section and the top of the reinforced concrete cylinder are fixedly connected by a screw and a nut, and pre-tensioning is provided by a steel strand located on the same diameter circle as the screw, and three leveling bolts for leveling the transition section are arranged at the bottom end of the transition section.

[0004] For example, the patent with application number CN201420391466.4 discloses a wind turbine tower, including a base, a concrete cylinder, a steel tower and a transition section for connecting the concrete cylinder and the steel tower. The concrete cylinder comprises a concrete layer, a permeable layer, an isolation layer and an anti-corrosion layer from the inside to the outside, and the inner wall of the steel tower is coated with an epoxy heavy anti-corrosion powder layer and an epoxy powder layer in sequence.

[0005] In the prior art, in order to improve the anti-corrosion effect of the transition section, zinc spraying treatment is performed on the surface of the transition section. However, the transition section is very heavy and needs to be placed on a special mobile device to be sent to the zinc spraying device and moved during the zinc spraying process. In the prior art, the transition section is usually placed on a mobile trolley and sent to the zinc spraying device for treatment. However, the contact point between the bottom of the transition section and the mobile trolley cannot be zinc sprayed, resulting in imperfect local zinc spraying, affecting product quality.

[0024] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0025] Example 1

[0026] See also Figure 1-6Embodiment 1 provides a special support frame for zinc spraying in the transition section of a wind tower, including a walking track 2, two walking structures 3 and four supporting structures 4. The walking track 2 is arranged in the front-to-back direction, and can be specifically composed of two steel rails (arranged in the front-to-back direction) arranged side by side. The two walking structures 3 are arranged side by side in the front and back directions, and both can move forward and backward on the walking track 2 (driven by the corresponding structure). Two supporting structures 4 are arranged side by side in the left and right sides on the side close to each other, which are specifically the front walking structure in the front and the rear walking structure in the rear. The four supporting structures 4 are arranged in a rectangular shape, which are specifically the left front supporting structure, the right front supporting structure, the left rear supporting structure and the right rear supporting structure. The left front supporting structure and the right front supporting structure are arranged side by side in the rear of the front walking structure, and the left rear supporting structure and the right rear supporting structure are arranged side by side in the front of the rear walking structure. Let the transition section 1 be located between the two walking structures 3 to reduce the possibility of zinc spraying on the walking structure 3. The two supporting structures 4 on the same walking structure 3 are respectively located on the lower left and right sides of the transition section 1. Specifically, the left front supporting structure, the right front supporting structure, the left rear supporting structure and the right rear supporting structure are respectively located at the left front, right front, left rear and right rear of the transition section 1 .

[0027] Among them, the support structure 4 includes a bracket 41 and a support roller 42 on its top, etc. The bracket 41 is fixed on the walking structure 3. The four support rollers 42 are all arranged horizontally, arranged in a rectangular shape (located on the same circle (coordinated with the bottom of the transition section 1)), and are located on the same horizontal plane to form a support surface. The support roller 42 is located on the lower side of the transition section 1, and is inclined from the outside to the inside toward another walking structure 3 (the walking structure 3 on the opposite side of the current walking structure 3), and a limiting convex ring 43 is coaxially provided on its outer end. The transition section 1 (vertically arranged, with the flange at the bottom) is placed on the support surface formed by the four support rollers 42, and the limiting convex ring 43 is located on the adjacent outer side of the transition section 1. The setting of the support roller 42 and the limiting convex ring 43 must ensure that while supporting the transition section 1, one walking structure 3 can move slightly forward or backward independently to expose the contact point.

[0028] When the transition section 1 is moved (such as when entering the zinc spraying equipment, leaving the zinc spraying equipment, or when the nozzle of the zinc spraying equipment is moved, etc.), the two walking structures 3 move synchronously (move forward or backward at the same time). When zinc is sprayed on the contact point between the bottom of the transition section 1 and the support structure 4, the current walking structure 3 (a walking structure 3 corresponding to the bottom of the transition section 1 and the support structure 4) moves away from the other walking structure 3 (moves forward or backward, just a slight movement (such as 2-5cm), so that the contact point at the bottom of the transition section 1 is exposed), and the other walking structure 3 remains stationary (through braking, walking drive racks or not through corresponding structures, etc.). Specifically, the transition section 1 has four contact points with the two walking structures 3. The front walking structure can be moved forward first to expose the two contact points in the front; after the zinc spraying of the two contact points in the front is completed, the rear walking structure is moved backward to expose the two contact points in the rear, and the two contact points in the rear are sprayed with zinc.

[0029] Preferably, the two walking structures 3 in the embodiment of the utility model are arranged symmetrically front and back about the left-right center line of the transition section 1, and the two supporting structures 4 on the same walking structure 3 are arranged symmetrically front and back about the left-right center line of the transition section 1. The supporting structures 4 are arranged close to the left-right center line of the transition section 1, such as the left front supporting structure and the left rear supporting structure are respectively located at the front and rear sides of the left-right center line of the transition section 1 and are arranged close to the center line.

[0030] Example 2

[0031] See also Figure 1-6 Embodiment 2 provides a special support frame for zinc spraying of the transition section of a wind tower, and its structure is basically the same as that of embodiment 1, except that: the special support frame in this embodiment is modified from two existing roller frames, and the wind tower production workshop has a large number of roller frames for transporting tower sections. The walking structure 3 is a roller frame arranged in the left and right directions, and two support bases 5 are arranged side by side on the left and right sides of the bottom of the roller frame. The two support bases 5 are respectively slidably arranged on two steel rails (the support bases 5 are driven by the corresponding structure to move on the steel rails, which is an existing structure and is omitted in detail in this embodiment) and at least two rollers are arranged side by side on the bottom of each of them. The support base 5 is arranged in the front and back directions and rollers are arranged at both ends. The rollers are arranged in the left and right directions and are slidably arranged on the steel rails on the corresponding sides. The inner end of the support base 5 extends inward relative to the inner side of the roller frame, and a support structure 4 is respectively arranged on the upper side of the inner ends of the two support bases 5, and the support roller 42 is located above the roller frame so that the transition section 1 is located above the roller frame. Then the two support structures 4 of the front roller frame are located behind the front roller frame to prevent zinc from being sprayed on the roller frame. Specifically, the front and rear ends of the support base 5 extend forward and backward respectively relative to the corresponding sides of the roller frame.

[0032] Among them, the bracket 41 in the embodiment of the utility model includes a bottom plate 11 and two vertical plates 12 arranged side by side thereon. The bottom plate 11 is arranged horizontally, and is fixed to the support base 5 by bolts (specifically four, four bolts are arranged vertically) (the support structure 4 can be removed from the roller frame by removing the bolts, so that the roller frame can be used for other purposes), and is specifically a rectangular plate. The vertical plate 12 is perpendicular to the support roller 42, and is specifically a vertically arranged rectangular plate, the lower end of which is welded and fixed to the upper side of the bottom plate 11, and is inclined relative to the walking track 2. The support roller 42 is located between the two vertical plates 12, and its two ends are respectively arranged on the two vertical plates 12, and its upper side is higher than the upper end of the vertical plate 12 to facilitate placing the transition section 1 on the support roller 42.
