Description

Technical Field

[0001] This utility model relates to a process equipment, and more particularly to a hoisting fixture for an exciter stator. Background Technology

[0002] Exciters often have a large number of poles, and currently, most exciter stators have their coils wound by machines. Because the operating platform of the coil winding equipment is relatively high off the ground, and the winding tray of the machine requires a high degree of precision to fit with the exciter, manual handling and installation are extremely inconvenient, time-consuming, and labor-intensive for larger exciter stators after coil winding, thus reducing production efficiency. Utility Model Content

[0003] In response to the aforementioned problems, the applicant has conducted research and improvements, and provides a hoisting fixture for exciter stators that has a simple and compact structure, low manufacturing cost, and is easy to operate and use. It avoids unnecessary bumps and damage to the workpiece, improves production efficiency, and reduces the labor intensity of operators.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A hoisting fixture for an exciter stator is characterized by comprising a cylindrical steel cylinder, three round steel bars arranged radially and evenly inside the steel cylinder, the outer ends of the round steel bars being fixedly connected to the inner wall of the steel cylinder, the inner ends of the round steel bars being fixedly connected to a connecting plate arranged in the center of the steel cylinder, a lifting ring being fixedly connected to the connecting plate, and at least three protrusions evenly arranged in the circumferential direction being fixedly arranged on the outer wall of the lower part of the steel cylinder.

[0006] Further:

[0007] The outer wall of the steel cylinder is provided with four protrusions.

[0008] The technical advantages of this utility model are as follows:

[0009] This utility model discloses a hoisting fixture for an exciter stator, which has a simple and compact structure, low manufacturing cost, and is easy to operate and use. It avoids unnecessary bumps and damage to the workpiece, improves production efficiency, and reduces the labor intensity of operators. Attached Figure Description

[0010] Figure 1 This is a three-dimensional structural diagram of the present invention.

[0011] Figure 2 This is a schematic diagram of the operating state of this utility model. Detailed Implementation

[0012] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0013] like Figure 1 As shown, this utility model includes a cylindrical steel cylinder 1, with three round steel bars 2 arranged radially and evenly inside the steel cylinder 1. The outer ends of the round steel bars 2 are welded to the inner wall of the steel cylinder 1, and the inner ends of the round steel bars 2 are welded to a connecting plate 4 located in the center of the steel cylinder 1. A lifting ring 5 is fixedly connected to the connecting plate 4. At least three protrusions 3 evenly arranged in the circumferential direction are fixedly arranged on the lower outer wall of the steel cylinder 1. The number of protrusions 3 can be determined according to the number and distribution of the pole pieces of the exciter stator being hoisted. In this utility model, four protrusions 3 are provided on the outer wall of the steel cylinder 1.

[0014] In actual operation, such as Figure 2 As shown, after the coil winding of the exciter stator 6 is completed, the hook of the hoisting equipment engages with the lifting ring 5 of this invention, and the hoisting fixture for the exciter stator is moved above the exciter stator 6. The hoisting fixture is lowered while its position is adjusted to ensure it is coaxial with the exciter stator 6, and the protrusion 3 of the hoisting fixture is aligned with the gap between the pole pieces of the exciter stator 6. The hoisting fixture can continue to lower until the protrusion 3 reaches its lowest position. After rotating at an angle, the hoisting fixture can be lifted, allowing the protrusion 3 to hook onto the pole pieces of the exciter stator 6, thus lifting the exciter stator 6 out of the coil winding equipment as a whole. This invention is easy to operate and use, avoids unnecessary bumps and damage to the workpiece, improves production efficiency, and reduces the labor intensity of operators.
