Description

Technical Field

[0001] The utility model relates to the technical field of fan disassembly, in particular to a tool and assembly for disassembling a fan impeller. Background Art

[0002] Fans are widely used in sintering, desulfurization and dust removal, blast furnaces, converters and other equipment to drive airflow into these equipment. At the same time, they control the air volume to ensure the normal operation of these equipment. In order to ensure that the fan can always operate normally, the fan needs to be inspected and maintained regularly. During maintenance, the fan shaft is stationary and the fan impeller needs to be removed from the shaft. Since the fan shaft and the impeller hub are connected by a clearance fit installation method, there is often debris deposited between the hub and the shaft, and the shaft and the hub are prone to rust and adhesion. Therefore, it is difficult to remove the impeller from the shaft.

[0030] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] As the background technology, usually, when removing the impeller of the fan from the rotating shaft, a jack is required. One person holds the jack, another person adjusts the position of the support seat that supports the base of the jack, and another person operates the jack to separate the impeller hub from the rotating shaft of the fan. The removal of the impeller is time-consuming and laborious.

[0032] To solve the above problems, refer to Figure 1 and Figure 2 The utility model provides a tool for disassembling a fan impeller, comprising a fixing seat 110, a connecting rod 120, a supporting seat 130, a jack 140 and a top column 150. The fixing seat 110 is suitable for being detachably connected to the hub of the impeller of the fan. A guide hole 111 is provided on the fixing seat 110 to limit the moving direction of the top rod. The axis of the connecting rod 120 is perpendicular to the surface where the fixing seat 110 is located, and one end is fixedly connected to the fixing seat 110 by welding. The surface where the supporting seat 130 is located is perpendicular to the axis of the connecting rod 120, and is fixedly connected to the other end of the connecting rod 120 by welding. The axis of the jack 140 is perpendicular to the surface where the supporting seat 130 is located. The base 141 of the jack 140 abuts against the supporting seat 130, and the screw 142 faces the fixing seat 110. The top column 150 is inserted into the guide hole 111, and one end abuts against the screw 142 of the jack 140.

[0033] The process and principle of removing the fan impeller with the help of the fan impeller removal tool are as follows:

[0034] First, install the fixing seat 110 on the hub of the impeller. Next, insert the top column 150 into the guide hole 111. Then, make the base 141 of the jack 140 abut against the support seat 130, and the screw rod 142 abut against one end of the top rod. Finally, the operator extends the screw rod 142 by operating the jack 140, and then moves the top rod, so that the hub of the impeller and the rotating shaft of the fan are separated from each other. Compared with the traditional disassembly method, the disassembly task can be completed by one person with the help of the fan impeller disassembly tool, which improves the disassembly efficiency and saves manpower. Moreover, it is not easy to cause damage to the hub during the disassembly process, avoiding the impeller from returning to the factory for repair and scrapping. The overall structure is simple, the manufacturing cost is low, and it is flexible to use.

[0035] Preferably, the fan impeller disassembly tool further includes a linear sleeve, which is installed in the guide hole 111 and can effectively reduce the degree of wear between the push rod and the fixing seat 110 when the push rod moves.

[0036] Specifically, in the exemplary embodiment, a long hole 112 is provided on the fixing seat 110, and the fixing seat 110 and the wheel hub are fixedly connected by screws through the long hole 112 and the threaded hole on the wheel hub, so as to facilitate the disassembly and assembly of the fixing seat 110 and the impeller wheel hub. Moreover, the long hole 112 makes the fixing seat 110 suitable for installation on wheel hubs of different sizes, so that the fan impeller disassembly tool has high versatility.

[0037] Preferably, the guide hole 111 is opened in the middle of the fixing seat 110. There are two elongated holes 112, which are respectively arranged on opposite sides of the guide hole 111, and the force is relatively uniform, which effectively improves the stability of the connection between the fixing seat 110 and the wheel hub, thereby improving the safety of operation.

[0038] Preferably, there are two connecting rods 120, one end of which is fixedly connected to the two opposite edges of the fixing seat 110 by welding, and the other end of which is fixedly connected to the two opposite edges of the supporting seat 130 by welding. In this way, the rigidity and strength of the overall structure are guaranteed.

[0039] Preferably, the fan impeller disassembly tool further comprises a base. The base 141 is fixedly mounted on the bottom surfaces of the two connecting rods 120 by welding, and the top surface is used to carry the jack 140 to prevent the jack 140 from falling spontaneously, thereby improving the safety of the operation.

[0040] In some embodiments, the fan impeller disassembly tool further includes a restraint belt. The opposite ends of the restraint belt are detachably connected to the hanging rings on the top surfaces of the middle parts of the two connecting rods 120 through hooks. The restraint belt can prevent the jack 140 from popping up when the force is too large and uneven, thereby improving the safety of the operation.

[0041] In other embodiments, the fan impeller disassembly tool does not include a restraining belt. Threaded holes are respectively provided on the base 141 of the jack 140 and the support seat 130, through which the jack 140 can be fixed to the support seat 130 using screws to prevent the jack 140 from popping up when the force is too large and uneven, thereby improving the safety of the operation.

[0042] Specifically, in the exemplary embodiment, the support seat 130 is in the shape of an elongated strip. The fixing seat 110 is in a circular structure, so that the fixing seat 110 is evenly stressed. The aperture of the guide hole 111 is 30 mm. The diameter of the fixing seat 110 is 250 mm, and the thickness along the axial direction is 20 mm. The length of the elongated hole 112 is 40 mm, and the width is 16 mm. The cross-sectional diameter of the top column 150 is 29 mm, and the axial length is 50 mm-80 mm.

[0043] Preferably, the fan impeller disassembly tool further comprises an articulated seat, a limiting sleeve and a handle. The articulated seat is fixedly mounted on the top surface of the support seat 130 by welding. The limiting sleeve is rotatably mounted on the articulated seat. One end of the handle can pass through the limiting sleeve and then be inserted into the operating sleeve 143 of the jack 140. In this way, the lever principle is used to make the operation of the jack 140 more labor-saving.

[0044] On the other hand, the utility model also provides a fan impeller disassembly assembly, including the fan impeller disassembly tool provided by any of the above embodiments. With the fan impeller disassembly tool, the disassembly task can be completed by one person, which improves the disassembly efficiency and saves manpower. Moreover, the hub is not easily damaged during the disassembly process, avoiding the impeller from being returned to the factory for repair and scrapping. The overall structure is simple, the manufacturing cost is low, the use is flexible, and the safety of operation is guaranteed.
