Description

Technical Field

[0001] This utility model relates to the field of rotary hot drying of wind turbine rotors after impregnation with paint, specifically a hot drying roller tooling. Background Technology

[0002] A company manufactures wind turbine rotors that require prolonged rotation and heat curing in an oven after impregnation with paint to ensure even paint distribution. Specifically, the oven directly drives a drum to rotate, which in turn drives the rotor to rotate, achieving rotor rotation and heat curing. This rotor heat curing process has the following problems:

[0003] (1) Apart from the main shaft, the rotor has no other support points on the drum of the drying room, and the surface of the rotor must not be damaged.

[0004] (2) It is not allowed to roll directly on the surface of the rotor spindle, as this will damage the spindle and affect the subsequent product assembly.

[0005] (3) The parts that come into contact with the rotor spindle need to be heat resistant, wear resistant, and have a hardness less than that of carbon steel to avoid scratching the spindle.

[0006] (4) The tooling should be as simple as possible during assembly to reduce labor and assembly time and improve work efficiency.

[0007] (5) The tooling must be stable and secure when rolling to avoid damaging the rotor.

[0008] Based on the above problems, there is a need to provide a hot drying roller fixture, which is installed on a rotor and directly drives the roller through the drying chamber. This allows the hot drying roller fixture to rotate directly with the rotor, thereby achieving the effect of rotational hot drying. Summary of the Invention

[0009] The technical problem this invention aims to solve is to provide a hot-drying roller fixture that addresses the shortcomings of the prior art. This hot-drying roller fixture allows the rotor to be mounted on the rollers of the drying chamber, and the drying chamber directly drives the rollers, causing the hot-drying roller fixture to rotate directly with the rotor, thus achieving the effect of rotary hot drying. The rotor does not directly contact the rollers of the drying chamber, protecting the rotor shaft. The fixture structure is simple, the assembly process between the fixture and the rotor shaft is simple and convenient, and the fixing method is stable and secure.

[0010] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0011] A hot-drying roller fixture includes a roller, a pull rod, and a pad;

[0012] The roller includes an outer ring, an inner ring, and ribs, with the outer ring connected to the inner ring via multiple ribs;

[0013] One end of the pull rod is connected to the outer ring of one roller, and the other end is connected to the outer ring of another roller.

[0014] The pad is used to make close contact with the outer surface of the spindle and is located inside the inner ring of the roller. The inner ring of the roller has multiple threaded through holes and the pad has multiple countersunk holes. The threaded through holes of the inner ring of the roller are connected to bolts, and the tail end of the bolt is inserted into the countersunk hole of the pad, thereby making the pad hold tightly against the outer surface of the spindle.

[0015] As a further improvement of this utility model, there are two rollers and three pull rods, and each roller has two arc-shaped pads on the inner side of its inner ring.

[0016] As a further improvement to this utility model, the roller is made of steel.

[0017] As a further improvement of this utility model, the outer ring of the roller is welded and fixed to one end of the rib plate, and the inner ring of the roller is welded and fixed to the other end of the rib plate.

[0018] As a further improvement of this utility model, both ends of the pull rod are provided with threads. One end of the pull rod passes through the through hole of the outer ring of a roller and is then locked to the outer ring by a nut and a flat washer. The other end of the pull rod passes through the through hole of the outer ring of another roller and is then locked to the outer ring by a nut and a flat washer.

[0019] As a further improvement of this utility model, grooves are also provided at both ends of the pull rod.

[0020] As a further improvement to this utility model, the pull rod is made of steel.

[0021] As a further improvement to this utility model, the pad is made of brass.

[0022] As a further improvement of this utility model, a nut is also threaded onto the bolt connected to the threaded through hole of the inner ring of the roller, and the nut is in close contact with the outer surface of the inner ring.

[0023] The beneficial effects of this utility model are as follows:

[0024] This invention allows the rotor, after being fitted with the hot-drying roller fixture, to be placed on the drum of the drying chamber. The drying chamber directly drives the drum, causing the hot-drying roller fixture to rotate directly with the rotor, thus achieving the effect of rotational hot drying. The rotor does not directly contact the drum of the drying chamber, which protects the rotor shaft. The fixture structure is simple, the assembly process between the fixture and the rotor shaft is simple and convenient, and the fixing method is stable and secure.

[0025] This utility model roller consists of an outer ring, an inner ring, and stiffening plates. The outer ring is welded together, which reduces costs while ensuring support. The inner ring is machined as a whole, requiring pre-machining of threaded through holes. The inner ring is then welded to the outer ring using stiffening plates, ensuring overall stability while reducing tooling weight and cost.

[0026] This utility model's pull rod adopts a double-threaded design, ensuring the required strength without compromising its durability. The outer surface of the pull rod is circular, making it inconvenient to clamp and rotate the nut. Therefore, grooves are machined at both ends of the pull rod to help secure it when tightening the nut.

[0027] To prevent the steel roller from directly contacting the spindle and damaging the spindle surface, this invention requires a material with a hardness lower than that of the roller, such as a brass pad. In order to ensure that the bolt can fix the pad, a countersunk hole is machined on the outer ring of the pad so that the bolt can be screwed into the countersunk hole.

[0028] This invention supports the roller disc fixture in a non-fitting position within the main shaft, and adds a copper pad between the roller disc and the main shaft to protect the main shaft from damage. To reduce bolt installation space, the fixing bolt is placed in the middle of the roller disc, i.e., on the inner ring, and a nut is added for locking, increasing the stability of the pad. Additionally, three tie rods are added to connect the roller discs at both ends, further increasing their stability. This simplifies manual assembly and increases the stability of the fixture, resulting in this invention. The assembly process is as follows: the roller disc is hoisted onto the rotating shaft, a pad is placed between the rotating shaft and the roller disc, and a double-structure locking mechanism of bolts and nuts is used. The bolts are inserted into the countersunk holes of the pad to prevent bolt movement and increase the pad's stability. Tie rods are used to connect the two roller discs at the middle, and nuts and flat washers are used to lock the roller discs on both sides to prevent displacement and increase overall stability. The fixture assembly is simple, reducing labor and assembly time, and improving work efficiency. The copper pad in contact with the rotor main shaft is high-temperature resistant, wear-resistant, and has a lower hardness than carbon steel, preventing scratches on the main shaft.

[0038] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0039] A hot drying roller 1 fixture includes a roller 1, a pull rod 2, and a pad 3.

[0040] like Figure 1-2 As shown, the roller 1 includes an outer ring 1A, an inner ring 1C, and stiffening plates 1B. The outer ring 1A is connected to the inner ring 1C through multiple stiffening plates 1B. The multiple stiffening plates 1B are evenly spaced.

[0041] The roller 1 is made of steel. The outer ring 1A is welded together, which reduces costs while ensuring support. The inner ring 1C is machined as a whole. A threaded through hole 1C1 needs to be pre-machined in the inner ring 1C. The inner ring 1C is then welded to the outer ring 1A with a stiffening plate 1B. This ensures overall stability while reducing tooling weight and cost.

[0042] One end of the pull rod 2 is connected to the outer ring 1A of one roller 1, and the other end is connected to the outer ring 1A of another roller 1.

[0043] like Figure 3 As shown, both ends of the pull rod 2 are threaded. One end of the pull rod 2 passes through the through hole 1A1 of the outer ring 1A of a roller 1 and is locked to the outer ring 1A by a nut 5 and a flat washer. The other end of the pull rod 2 passes through the through hole 1A1 of the outer ring 1A of another roller 1 and is locked to the outer ring 1A by a nut 5 and a flat washer.

[0044] like Figure 3 As shown, the tie rod 2 uses a double-threaded design, which ensures the required strength without compromising its strength. Grooves 2A are machined at both ends of the tie rod 2 to secure it when the nut 5 is tightened. The tie rod 2 is made of steel.

[0045] like Figure 4-5As shown, the pad 3 is used to make close contact with the outer surface of the main shaft 6 and is located inside the inner ring 1C of the roller 1. The inner ring 1C of the roller 1 has multiple threaded through holes 1C1, and the pad 3 has multiple countersunk holes 3A. Bolts 4 are threaded into the threaded through holes 1C1 of the inner ring 1C of the roller 1, and the tail end of the bolt 4 is inserted into the countersunk hole 3A of the pad 3, thereby making the pad 3 hold tightly against the outer surface of the rotor main shaft 6. The pad 3 is made of brass.

[0046] To prevent the steel roller from directly contacting the spindle 6 and damaging its surface, a material with a hardness lower than that of the roller 1 is required. In order to ensure that the bolt 4 can fix the pad 3, a countersunk hole 3A is machined on the outer ring of the pad 3 so that the bolt 4 can be screwed into the countersunk hole 3A.

[0047] In this embodiment, there are 2 rollers 1 and 3 pull rods 2. Each roller 1 has 2 arc-shaped pads 3 on the inner side of its inner ring 1C.

[0048] In this embodiment, the outer ring 1A of the roller 1 is welded and fixed to one end of the rib plate 1B, and the inner ring 1C of the roller 1 is welded and fixed to the other end of the rib plate 1B.

[0049] In this embodiment, as Figure 6-7 As shown, a nut 5 is also threaded onto the bolt 4 connected to the threaded through hole 1C1 of the inner ring 1C of the roller 1, and the nut 5 is in close contact with the outer surface of the inner ring 1C.

[0050] In this embodiment, to reduce the installation space of bolt 4, the fixing bolt 4 is placed in the middle of roller 1, and a nut 5 is added to lock it in place, increasing the stability of the pad 3. Additionally, three tie rods 2 are added to connect the two ends of roller 1, further increasing the stability of roller 1. This simplifies manual assembly and increases the stability of the tooling.

[0051] 1. Hoist the roller 1 onto the rotor spindle 6. Place two pads 3 between the rotor spindle 6 and the inner ring 1C of the roller 1. Lock them with a double structure of bolts 4 and nuts 5. Insert the bolts 4 into the countersunk holes 3A of the pads 3 to prevent the bolts 4 from moving and increase the stability of the pads 3.

[0052] 2. A tie rod 2 is used to connect the two end rollers 1 in the middle, and nuts 5 are used to lock the two sides of the rollers 1 to prevent the rollers 1 from shifting and increase the overall stability.

[0053] After installing the rotor onto the roller fixture, place it on the drying oven drum 7, as follows: Figure 8-9 As shown, by directly driving the roller 7 through the drying chamber, the roller fixture in this embodiment can rotate directly with the rotor, thereby achieving the effect of rotary heat drying.
