Description

Technical Field

[0001] This invention relates to the field of passenger transport device technology, and in particular to a tool and method for manufacturing a drive device for a passenger transport device. Background Technology

[0002] Passenger transport devices, such as escalators or moving walkways, require drive units to operate. During assembly, drive units have numerous dimensional requirements, such as the parallelism between pulleys and the adjustment of brake clearance. These all require the use of different measuring tools to measure dimensions. If general-purpose measuring tools are used, positioning is often unreliable, measurement is cumbersome, and the measurement accuracy is not high. If specialized tools are made, multiple tools usually need to be designed for each measurement scenario and dimension. Summary of the Invention

[0003] The technical problem to be solved by this invention is: how to design a manufacturing tool that is simple in structure, small in size and easy to use, and can meet the measurement of multiple assembly dimensions of the drive device. This is the current technical problem.

[0004] To solve the above-mentioned technical problems, the present invention provides a tool for manufacturing a drive device for a passenger transport device, comprising a first body and a second body;

[0005] The first body is a rectangular flat body, and the second body is fixed to the first body in the height direction. After fixing, the first body and the second body form a T-shape.

[0006] The outer surface of the first body in the height direction is the first reference surface, and the lower surface of the second body is the first measuring surface. The first measuring surface is parallel to the first reference surface, and there is a first dimension between the first measuring surface and the first reference surface. The first dimension is used to measure the parallelism between the end face of the motor pulley of the drive device and the drive pulley.

[0007] The second body also has a stepped surface, which is parallel to the first measuring surface. A second dimension is provided between the stepped surface of the second body and the first measuring surface. The second dimension is used to measure the bolt head height of the brake release device on the drive unit.

[0008] Preferably, the first body is made of a magnetic material.

[0009] Preferably, the manufacturing tool further includes a third body, which is fixed to the second body in the length direction; the lower surface of the third body is flush with the lower surface of the second body, and the upper surface of the third body is lower than the upper surface of the second body; the upper surface of the third body is parallel to the first measuring surface, and there is a fourth dimension between the upper surface of the third body and the first measuring surface, the fourth dimension being used to measure the bolt head height of the brake release device on the drive device.

[0010] Preferably, the third body has a stepped surface, the stepped surface of the third body is parallel to the first measuring surface, and there is a third dimension between the stepped surface of the third body and the first measuring surface. The third dimension is used to measure the bolt head height of the brake release device on the drive device.

[0011] Preferably, the second body has a fifth dimension in the width direction, the fifth dimension being used to measure the brake's hold stroke.

[0012] Preferably, the thickness of the third body in the width direction is less than the thickness of the second body in the width direction, and the thickness of the third body in the width direction has a sixth dimension, which is used to measure the hold stroke of the brake.

[0013] Preferably, a T-shaped through hole is provided in the middle of the second body, and the upper two protrusions of the T-shaped through hole have a seventh dimension in the height direction. The seventh dimension is used to measure the installation dimensions of the friction plate wear detection switch.

[0014] The present invention also provides a method for manufacturing a drive unit of a passenger conveying device, the method being used to measure the parallelism between the end face of the motor pulley and the drive pulley, comprising the following steps:

[0015] Step S1: Fix the ruler to the output shaft of the motor pulley, so that it contacts the end face of the motor pulley;

[0016] Step S2: Attach the two aforementioned manufacturing tools to the inside of the ruler near the drive pulley, one near the lower part of the drive pulley and the other near the upper part of the drive pulley;

[0017] Step S3: Determine the parallelism between the end face of the motor pulley and the drive pulley by visually inspecting or measuring the gap between the two manufacturing tools and the drive pulley.

[0025] This invention provides a tool for manufacturing a drive unit for a passenger transport device, such as... Figure 1 As shown, the manufacturing tool has a first body 1, a second body 2, and a third body 3;

[0026] exist Figure 1 In the diagram, X represents the length direction, Y represents the height direction, and Z represents the width direction. The first body 1 is a rectangular flat body with a thickness of approximately 3 mm in the height direction. The second body 2 has a thickness of 2.5 mm in the width direction and is fixed to the first body 1 in the height direction. After fixing, the first body 1 and the second body 2 form a T-shape. The outer surface of the first body 1 in the height direction is a first reference surface 11, and the first body 1 is made of a magnetic material. The lower surface 21 of the second body is a first measuring surface 21, which is parallel to the first reference surface 11. A first dimension A1 exists between the first measuring surface 21 and the first reference surface 11, and this first dimension A1 is used to measure the parallelism between the end face of the motor pulley and the drive pulley of the drive device. The third body 3 is fixed to the second body 2 in the length direction. The lower surface 31 of the third body is flush with the lower surface 31 of the second body, and the upper surface 32 of the third body is lower than the upper surface 22 of the second body. The third body 3 and the second body 2 can be integrally formed. The thickness of the third body 3 in the width direction is less than the thickness of the second body 2 in the width direction. Preferably, the thickness of the third body 3 in the width direction is 1.5 mm.

[0027] like Figure 2As shown, this embodiment also provides a method for manufacturing a drive device for a passenger transport device. The manufacturing method is used to measure the parallelism between the end face of the motor pulley and the drive pulley. The manufacturing method includes: step S1, fixing a ruler to the output shaft of the motor pulley and contacting the end face of the motor pulley; step S2, adsorbing two of the aforementioned manufacturing tools on the inside of the ruler near the drive pulley, one near the lower part of the drive pulley and the other near the upper part of the drive pulley; step S3, judging the parallelism between the end face of the motor pulley and the drive pulley by visually inspecting or measuring the gap between the two manufacturing tools and the drive pulley.

[0028] The second body 2 also has a stepped surface 23, which is parallel to the first measuring surface 21. A second dimension A2 is provided between the stepped surface of the second body 2 and the first measuring surface 21. The second dimension A2 is used to measure the bolt head height of the brake release device on the drive device.

[0029] The third body 3 also has a stepped surface 33, which is parallel to the first measuring surface 21. There is a third dimension A3 between the stepped surface of the third body 3 and the first measuring surface 21. The third dimension A3 is also used to measure the bolt head height of the brake release device on the drive unit.

[0030] The upper surface of the third body 3 is parallel to the first measuring surface 21. There is a fourth dimension A4 between the upper surface of the third body 3 and the first measuring surface 21. The fourth dimension A4 is also used to measure the bolt head height of the brake release device on the drive unit.

[0031] Figure 3 This diagram illustrates the bolt head height of the brake release device on a drive unit. Different second dimensions A2, third dimensions A3, and fourth dimensions A4 can be applied to drive units with different specifications.

[0032] Figure 4 This diagram illustrates the retained stroke between the electromagnet push rod and its corresponding bolt push rod of the brake on the drive device. This retained stroke can be measured using this manufacturing tool, specifically by measuring the thickness of the second body 2 in the width direction or the thickness of the third body 3 in the width direction. Specifically, the thickness of the second body 2 in the width direction has a fifth dimension, and the thickness of the third body 3 in the width direction has a sixth dimension. This fifth or sixth dimension is used to measure the retained stroke of the brake.

[0033] In the middle of the second body 2, there is a T-shaped through hole 24. The upper two protrusions of the T-shaped through hole 24 have a seventh dimension A7 in the height direction. The seventh dimension A7 is used to measure the installation dimension of the friction plate wear detection switch. Figure 5This diagram illustrates the installation of a brake friction pad wear detection switch on a drive unit. The installation dimensions of the switch can be easily measured using a T-hole. For example, if the head of the wear detection switch passes directly through the T-hole to the flat nut, the dimensions are correct. Using ordinary measuring tools would require separately measuring the exposed head and the flat nut, which is very inconvenient.

[0034] The present invention has been described in detail above through specific embodiments and examples, but these are not intended to limit the invention. Many modifications and improvements can be made by those skilled in the art without departing from the principles of the invention, and these should also be considered within the scope of protection of the present invention.
