Description

Technical Field

[0001] The utility model relates to the technical field of air preheaters, in particular to a base. Background Art

[0002] At present, the air preheater of a thermal power plant is driven by an electric motor to drive the reducer, and the motor and reducer are softly connected together through a permanent magnetic disk. The reducer is fixed on the air preheater body, and the motor base is fixed on the boiler steel frame. As the unit load changes, the air preheater expands and changes. Since the expansion change of the boiler steel frame is different from that of the air preheater, the expansion displacement of the base and the air preheater is different, which causes the disk gap between the motor and the reducer to change. When the disk gap is too large, it will cause abnormal heating of the disk, and when the disk gap is too small or even close, it will cause the disk to wear, making the air preheater operation unable to meet the safe and stable operation requirements.

[0029] like Figure 1 and Figure 2As shown, this embodiment provides a base, which includes a base plate 1, a bearing plate 2, a stiffening plate 3 and a reinforcement member 4. The base plate 1 is used to connect the air preheater, the bearing plate 2 is connected to the base plate 1 and is extended in the horizontal direction, and a mounting platform 21 is provided on the bearing plate 2.

[0030] In this embodiment, the base plate 1 is used to connect the air preheater to ensure a stable connection between the entire base and the air preheater. The bearing plate 2 is connected to the base plate 1 and extends in the horizontal direction to provide a stable mounting platform 21 for the motor, reduce vibration and displacement, and make the motor and the air preheater located on the same overall structure, avoiding the expansion deformation of the air preheater and causing the motor and the air preheater to have inconsistent deformation and displacement. The motor is connected to the reducer through a magnetic coupling, and the reducer can drive the air preheater to operate, so that the disk gap between the motor and the reducer can be kept relatively stable, and the operation is more stable and safe. The two ends of the stiffening plate 3 are respectively connected to the base plate 1 and the bearing plate 2, which enhances the structural rigidity and stability of the entire base. The reinforcement 4 is arranged at the bottom end of the bearing plate 2 along the extension direction of the bearing plate 2 and connected to the base plate 1, which helps to maintain the overall stability of the base when the air preheater expands. Through the above arrangement, the base of this embodiment can keep the disk gap between the motor and the reducer relatively stable, and the operation of the air preheater is safer and more stable.

[0031] It should be noted that the motor, magnetic coupling, reducer and air preheater are all conventional equipment in this field. The technical personnel in this field are clear about their specific working principles, which will not be repeated here.

[0032] Specifically, Figure 1 and Figure 2 As shown, the base plate 1 is extended in the vertical direction and can be fixedly connected to the outer wall of the air preheater, further enhancing the connection stability and reliability between the base and the air preheater. In addition, the base plate 1 and the air preheater can be fixedly connected by screw connection, welding or the like.

[0033] More specifically, if Figure 1 and Figure 2 As shown, in this embodiment, a plurality of bolt holes 11 are provided on the base plate 1, and a plurality of bolt members can respectively pass through the plurality of bolt holes 11 and be screwed to the air preheater. The plurality of bolt members can withstand greater tensile and shear forces, ensuring that the connection between the base and the air preheater is firm and reliable, and is convenient for disassembly and maintenance of the components.

[0034] Specifically, Figure 1 and Figure 2As shown, the diameter of one end of the supporting plate 2 gradually decreases toward the direction close to the substrate 1, so that the supporting plate 2 can still maintain a stable connection with the substrate 1 when deformed, reducing failures or damages caused by deformation.

[0035] Specifically, Figure 1 and Figure 2 As shown, a weight-reducing hole 22 is provided at one end of the carrying plate 2 close to the base plate 1 to reduce the weight of the carrying plate 2 itself and facilitate transportation, installation and maintenance.

[0036] Specifically, Figure 1 and Figure 2 As shown, a plurality of spaced connection holes 23 are provided at one end of the carrier plate 2 away from the base plate 1 . The connection holes 23 are used to connect the motor to ensure that the motor can be stably and evenly fixed on the carrier plate 2 .

[0037] Specifically, Figure 1 and Figure 2 As shown, the base also includes a fixing platform 5, which is detachably connected to the bearing plate 2, such as by bolt connection, snap connection, etc., to facilitate the installation and disassembly of various components. The motor is installed on the fixing platform 5, and the stability and safety of the motor are ensured by the support and fixation of the fixing platform 5.

[0038] Specifically, Figure 1 and Figure 2 As shown, the reinforcement 4 includes a crossbeam and reinforcement ribs 41. A plurality of reinforcement ribs 41 are provided on the crossbeam. The plurality of reinforcement ribs 41 are arranged at intervals in the horizontal direction to ensure that the entire structure can evenly distribute stress when subjected to external loads, thereby improving the structural strength of the base and enabling it to withstand greater loads and impact forces.

[0039] More specifically, if Figure 1 and Figure 2 As shown, along the vertical direction, the cross section of the reinforcement member 4 is I-shaped, which can significantly improve the bearing capacity and stability of the structure.

[0040] Specifically, Figure 1 and Figure 2 As shown, the base also includes ribs 6, and the ribs 6 and stiffening plates 3 are respectively arranged on opposite sides of the load-bearing plate 2, so as to improve the performance of the overall structure by bearing part of the load and transferring it to other structural parts, thereby enhancing the local stability and bearing capacity of the load-bearing plate 2. The extension direction of the ribs 6 is set at an angle to the extension direction of the stiffening plates 3, so that the ribs 6 and stiffening plates 3 can cooperate with each other when bearing forces and moments in different directions, thereby jointly improving the stability and bearing capacity of the load-bearing plate 2.

[0041] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here.
