Description

Technical Field

[0001] This utility model relates to the field of blower impeller repair and replacement technology, and in particular to a tooling for disassembling the impeller. Background Technology

[0002] A blower is a device capable of conveying large quantities of air or other gases, playing a crucial role in many fields: 1. Industrial sector: Metallurgical industry: In blast furnace ironmaking, blowers blow a large amount of air into the furnace to provide sufficient oxygen for coke combustion, increase furnace temperature, promote iron ore reduction, accelerate the smelting process, and improve the output and quality of molten iron.

[0003] In the chemical industry: it is used for material transportation, such as pneumatically transporting powdered materials to a designated location via pipelines; in chemical reactions, it provides the oxygen or other gases required for the reaction to ensure the smooth progress of the reaction.

[0004] 2. Environmental Protection Sector: Wastewater treatment: In the aeration tank, blowers introduce oxygen into the wastewater through aeration, meeting the growth and metabolic needs of aerobic microorganisms, enabling them to decompose organic matter in the wastewater and achieve wastewater purification.

[0005] Waste gas treatment: Some waste gas treatment processes require the collection and transportation of waste gas to treatment equipment. Blowers provide power to ensure that the waste gas enters the treatment system smoothly for purification.

[0006] 3. Building and HVAC sector: Ventilation: In large buildings, basements, workshops and other places, blowers can bring in fresh air and expel stale air, improve indoor air quality and maintain air circulation.

[0007] Air conditioning system: In a centralized air conditioning system, the blower is an important component of the air conditioning unit. It promotes air circulation and distributes the treated hot or cold air evenly to each room to regulate the indoor temperature.

[0008] In practical use, the impeller surface is prone to wear, so regular maintenance and replacement are necessary to ensure the normal operation of the blower. Additionally, some impellers are mounted on the motor or reducer shaft; when replacing the motor or reducer, the impeller must be removed first. The traditional method for removing an impeller typically involves inserting a U-shaped plate into the gap between the motor and the impeller, and making two round holes in the middle of the U-shaped plate (e.g.,...). Figure 1 and Figure 4As shown in the diagram, a lead screw is inserted through the round hole. One end of the lead screw is fixed to the round hole of the U-shaped plate, and the other end is fixed to the baffle of the jack (a piece with a diameter larger than the wind turbine and a thickness determined by the wind turbine diameter) or the pull claw of the coupling puller. Pulling force is applied by rotating the central screw, pulling the wind turbine off the motor shaft. The thickness and size of the U-shaped plate, the length and thickness of the lead screw, and the specifications of the puller should be determined according to the diameter of the wind turbine. However, this method has many problems. Because the U-shaped plate is in close contact with the guide shield, the guide shield will bear a large pressure. The U-shaped plate is not a ring-shaped force-bearing structure, and the opening is not stressed, so the force on the U-shaped plate is uneven, and the pressure on the guide shield is also uneven. This makes the guide shield prone to deformation, resulting in damage to the guide shield and rendering the wind turbine deformed and unusable. In summary, the traditional disassembly method causes significant damage to the wind turbine. It is not only inconvenient to disassemble, but also requires many tools, increasing the labor intensity of workers. Wind turbine damage increases the cost of spare parts and production costs. Utility Model Content

[0009] To address the aforementioned technical problems, a tooling for disassembling a wind turbine is provided. The technical means employed in this utility model are as follows: A tooling for disassembling a wind turbine includes: a steel plate, a set screw, a nut, and fixing bolts. The steel plate has mounting grooves on both sides, and fixing bolts are fitted into each of these grooves. These fixing bolts are used to fix the steel plate to threaded holes on both sides of the wind turbine shaft end face, ensuring close contact between one side of the steel plate and the wind turbine shaft end face. A through hole is formed in the middle of the steel plate, and the nut is fixed to the other side of the steel plate and coaxially arranged with the through hole. The mounting grooves are located on both sides of the nut, and the set screw is threadedly connected to the nut and extends through the through hole, serving to press against the center of a motor or reducer shaft.

[0010] Furthermore, the steel plate 1 is rectangular in shape.

[0011] Furthermore, the assembly slots on both sides are axially symmetrically distributed at the center of the steel plate.

[0012] Furthermore, the nut is welded to the steel plate.

[0013] Furthermore, two long strips are welded to the surface of the steel plate in the same direction as the nut, and the two long strips are symmetrically arranged on both sides of the nut.

[0014] Furthermore, the elongated block has a thickness of 10 mm, a height of 10 mm, and a length consistent with the length of the steel plate on the side of the nut.

[0015] Compared with the prior art, the present invention has the following advantages: The tooling for disassembling a wind turbine provided by this utility model has a simple and convenient structure. It adopts the design principle of bolt screwing in and nut fixing, which uses the bolt screwing force to pull out the wind turbine shaft. It can be operated by connecting the bolt of the rectangular steel plate assembly slot with the internal thread of the wind turbine shaft bolt along the bolt screwing distance. Subsequently, the wind turbine can be pulled out by the continuous force of the rectangular steel plate bolt through the nut. The overall operation is simple and convenient, saving the time of workers to inspect and maintain the wind turbine. At the same time, because the rectangular steel plate is in uniform contact with the wind turbine shaft and does not contact the guide shield, the wind turbine is not prone to deformation during the traction process, reducing the damage to the wind turbine and effectively reducing production costs.

[0016] Based on the above reasons, this utility model can be widely promoted in fields such as blower impeller maintenance. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Traditional methods often involve using jacks or couplings to pull the impeller, connecting a U-shaped plate to a lead screw, and then applying tension through a rotating central screw for disassembly. This method can cause uneven stress on the impeller, leading to deformation and damage to the impeller. Furthermore, traditional methods are not only inconvenient to disassemble, but also require a large number of tools, increasing the labor intensity of workers. Damage to the impeller also increases spare parts costs and production costs. This invention provides a tooling for disassembling impellers, specifically for blower impeller maintenance, to solve the problems associated with traditional impeller disassembly methods.

[0026] Please see Figure 2 , Figure 3 , Figure 5 This utility model provides a technical solution: a tooling for disassembling a wind turbine, comprising a rectangular steel plate 1, a set screw 2, a nut 3, and a fixing bolt 4. The rectangular steel plate 1 has symmetrically distributed mounting slots on the left and right sides. A through hole is formed at the center of the rectangular steel plate 1, and a nut 3 is welded and fixed above the hole to work with the set screw 2 (the nut 3 is welded to the hole in the middle of the rectangular steel plate 1, and the set screw 2 can pass through this hole after being screwed into the nut 3). The mounting slots are located on both sides of the nut 3 and are axially symmetrically distributed at the center of the rectangular steel plate 1. Adjustable fixing bolts 4 are installed at the mounting slots, corresponding to the threaded holes on the end face of the wind turbine shaft, so that the rectangular steel plate 1 is in close contact with the end face of the wind turbine shaft. Screw the nut 3 into the set screw 2 and through the center hole of the steel plate 1 to the center of the motor or reducer shaft. Use a long wrench or an eye wrench to screw the set screw 2 clockwise. The set screw 2 is now pressed against the center of the motor or reducer shaft. As the set screw 2 is screwed in, the nut 3 welded to the rectangular steel plate 1 moves outward along with the screw 2. The fixing bolt 4, which is installed in the mounting slot of the rectangular steel plate 1 and connected to the threaded hole on the end face of the wind turbine shaft, drives the wind turbine to move outward, thereby removing the wind turbine and completing the wind turbine removal operation.

[0027] The dimensions of the assembly slot, the specifications of the bolts and nuts, etc., should be determined according to the size of the disassembled impeller.

[0028] If there is no threaded hole on the end face of the wind turbine shaft, you can first drill a hole with an electric drill, and then use a tap to fit the hole. The selected tap should match the drill bit of the electric drill. The diameter of the selected tap and the drill bit of the electric drill should match the fixing bolt 4 required for disassembling the wind turbine.

[0029] In addition, to prevent the rectangular steel plate 1 from deforming under stress, thus affecting its subsequent performance, long strips with a thickness of 10 mm, a height of 10 mm, and a length consistent with that of the rectangular steel plate 1 can be welded to the two long sides of the rectangular steel plate 1 in the same direction as the welding nut 3, thereby increasing its strength.

[0030] Working principle: like Figure 2 , Figure 3 and Figure 5 As shown, during the use of this utility model tooling, firstly, the fixing bolts 4 are passed through the mounting slots on both sides of the rectangular steel plate 1 and connected to the threaded holes on the end face of the wind turbine shaft, so that the rectangular steel plate 1 is in close contact with the end face of the wind turbine shaft. Then, the set screw 2 is screwed into the nut 3 and passes through the center hole inside the steel plate 1 to reach the center of the motor or reducer shaft. Using a long wrench or an eye wrench, the set screw 2 is screwed in clockwise. Using the principle of leverage, the screwed set screw 2 is subjected to force, and the nut 3 moves outward along with the screwed set screw 2, thereby disassembling the wind turbine; thus completing the disassembly of the wind turbine.

[0031] This invention, through observation, reveals that by screwing in the set screw 2, force is applied to move the wind turbine, thus completing the disassembly operation. The force point for disassembling the wind turbine is the end face of the turbine shaft, not the turbine guide shield, thereby avoiding uneven force distribution that could easily cause deformation and damage to the turbine. To ensure proper turbine replacement, this tooling needs to be custom-made according to the turbine's dimensions when using this method for maintenance and replacement. In summary, traditional replacement methods for wind turbines are not only inconvenient, increasing the labor intensity of workers, but also increase the cost of spare parts and production costs due to the turbine's susceptibility to deformation and damage. Using the disassembly tooling of this invention for wind turbine replacement reduces production costs and improves work efficiency.

[0032] This utility model is simple and convenient to operate, saving employees time in inspecting and maintaining the wind turbine. At the same time, because the steel plate and the shaft end face are subjected to uniform force, the wind turbine is not prone to deformation during replacement, reducing wind turbine damage and effectively lowering production costs.

[0033] The tooling for disassembling a wind turbine according to this utility model is not limited to the above-described embodiments. Other structural designs obtained by using the same or similar structure as the above-described embodiments of the tooling for disassembling a wind turbine according to this utility model are all within the protection scope of the tooling for disassembling a wind turbine according to this utility model.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
