A tool for disassembling and repairing AFC fan door motors

Abstract

This utility model relates to the field of maintenance tool technology, specifically to a disassembly and maintenance tool for an AFC fan door motor. It includes a mounting plate and several fixing screws: a top support screw slidably mounted on the mounting plate; and multiple fixing screws arranged in an array around the top support screw, penetrating the mounting plate. This AFC fan door motor disassembly and maintenance tool uses the arrayed fixing screws on the mounting plate to screw into pre-drilled screw holes in the end cover, securely fixing the mounting plate to the end cover. The top support screw is screwed downwards with a nut and aligned with the motor shaft. When the handle is held and the top support screw is turned, the stationary nature of the motor causes the mounting plate to lift, lifting the end cover and allowing for separation and adjustment of the brake pads from the motor shaft. This tool provides uniform force, ensuring the motor is not damaged during disassembly and facilitating brake pad adjustment or replacement by maintenance personnel.

Description

Technical Field

[0001] This utility model belongs to the field of maintenance tool technology, specifically relating to an AFC fan door motor disassembly and maintenance tool. Background Technology

[0002] The AFC (Automatic Fare Collection) gate motor is the core power component of the subway's AFC gate system. Through precise drive control, it ensures smooth opening and closing of the gate gates while maintaining safety. The internal brake pads are prone to wear under prolonged high-frequency use and require periodic adjustment of the clearance or replacement.

[0003] However, corrosion easily occurs between the motor brake pad cover and the motor shaft, making cover removal difficult. Maintenance personnel must apply even force to move the cover during disassembly to avoid damaging the motor. Traditional disassembly methods cannot meet this requirement, failing to efficiently and safely remove the cover, thus posing a challenge to brake pad adjustment or replacement. Therefore, a disassembly and maintenance tool for AFC fan door motors is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a tool for disassembling and repairing AFC fan door motors that applies force evenly in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A tool for disassembling and repairing an AFC fan door motor, including a mounting plate, and also including:

[0007] A top support screw, which is slidably mounted on the mounting plate;

[0008] The mounting plate is equipped with multiple fixing screws arranged in an array around the top support screw, and the fixing screws pass through the mounting plate.

[0009] As a further optimization of this utility model, a nut is fixedly provided on the mounting plate, and the top support screw is threadedly connected to the nut.

[0010] As a further optimization of this utility model, a limiting ring is fixedly provided on the fixing screw, and the limiting ring and the head of the fixing screw are respectively located on the upper and lower sides of the mounting plate.

[0011] As a further optimization of this utility model, the lower end of the top support screw has an inverted frustum structure.

[0012] As a further optimization of this utility model, the mounting plate is provided with multiple through holes, and the top support screw and the fixing screw pass through the mounting plate through the through holes.

[0013] As a further optimization of this utility model, a handle is provided on one side of the mounting plate.

[0014] The beneficial effects of this utility model are as follows:

[0015] Unlike existing technologies, in actual use, multiple fixing screws arranged in an array on the mounting plate can be screwed into the pre-drilled screw holes on the end cover to securely fix the mounting plate to the end cover. The top support screw is screwed downwards through the nut and aligned with the motor shaft. When the handle is held and the top support screw is turned, the fixed motor characteristic causes the mounting plate to lift, thereby separating the brake pads from the motor shaft for adjustment. This tool provides a uniform force, ensuring that the motor is not damaged during disassembly and facilitating brake pad adjustment or replacement by maintenance personnel.

[0021] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Example 1

[0023] like Figure 1 - Figure 4 As shown, an AFC fan door motor disassembly and repair tool includes a mounting plate 1, a handle 11 on one side of the mounting plate 1, and multiple through holes 12 on the mounting plate 1. The mounting plate 1 serves as the basic support component of the entire tool, providing a mounting platform for other parts. The handle 11 on one side makes it easy for maintenance personnel to grip, allowing for more stable operation of the tool during disassembly and improving operational convenience.

[0024] A top support screw 2 is slidably mounted on the mounting plate 1, and a nut 21 is fixedly mounted on the mounting plate 1. The top support screw 2 and the nut 21 are threadedly connected. The lower end of the top support screw 2 has an inverted frustum structure. The threaded connection between the top support screw 2 and the nut 21 allows the top support screw 2 to move up and down by rotation, enabling precise position adjustment. The sliding design ensures smooth movement of the top support screw 2, avoiding jamming that could affect operation. The inverted frustum structure at the lower end allows for better alignment with the motor shaft 41.

[0025] Multiple fixing screws 3 are rotatably mounted on the mounting plate 1, arranged in a circular array with the top support screw 2 as the center. Each fixing screw 3 is fixed with a limiting ring 31. The limiting ring 31 and the heads of the fixing screws 3 are located on the upper and lower sides of the mounting plate 1, respectively. The arrangement of the multiple fixing screws 3 with the top support screw 2 as the center allows for fixing the mounting plate 1 to the end cover 51 from multiple directions during installation, ensuring stability and uniformity of the fixation and preventing damage to the end cover 51 due to uneven force. The rotatable arrangement of the fixing screws 3 facilitates screwing into the screw holes 52 of the end cover 51, making operation more flexible. The limiting ring 31 prevents the fixing screws 3 from falling off the mounting plate 1 and limits their range of movement, ensuring they remain in the correct installation position without affecting their rotation, thus ensuring smooth disassembly.

[0026] The top support screw 2 and the fixing screw 3 pass through the mounting plate 1 through the through hole 12. The through hole 12 provides a channel for the installation and movement of the top support screw 2 and the fixing screw 3, ensuring that each component can be accurately installed and function, while also making the tool structure more compact and reasonable.

[0027] It should be noted that the working principle of this AFC fan door motor disassembly and repair tool is as follows: When disassembling the motor brake pads, first loosen the fixing hex screws of the upper end cover 51 of the brake 5. Then, screw the multiple fixing screws 3 arranged in an array with the top support screw 2 as the center on the tool mounting plate 1 into the screw holes 52 reserved in the end cover 51 to fix the mounting plate 1 to the end cover 51. At the same time, screw the top support screw 2 downward through the nut 21 until the bottom of the top support screw 2 is aligned with the motor shaft 41 of the motor 4. Then, hold the handle 11 on one side of the mounting plate 1 and use a screwdriver to turn the top support screw 2. Since the motor 4 is fixed, the mounting plate 1 can drive the end cover 51 to rise during the rotation of the top support screw 2. This allows the end cover 51 to move outward from the motor shaft 41, so that the brake pads are separated from the motor shaft 41 and adjusted to a suitable distance, or the entire disassembly and replacement can be completed.

[0028] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
