Description

Technical Field

[0001] This utility model belongs to the field of inspection and measurement technology, specifically relating to a device for measuring the dimensions of side doors of high-speed trains. Background Technology

[0002] Currently, the maintenance schedule for high-speed trains stipulates that the dimensions of each mechanism of the side doors must be checked and measured every 90,000 kilometers or 90 days to ensure that the dimensions of each mechanism meet the requirements. The dimensions of these side door mechanisms play a decisive role in the normal opening and closing of the side doors. If dimensional issues affect the normal opening and closing of the side doors, it will cause delays in train operations and may even endanger the lives and property of passengers. In most cases, hex socket wrenches are used as measuring tools when measuring side doors. This method yields results with significant errors and is not accurate enough. Furthermore, during the measurement process, the hex socket wrench needs to be adjusted to a specified direction to measure specific areas. This measurement method requires precise control of the measuring angle, which can easily cause inconvenience, affecting work efficiency and measurement results. This is especially true when the measuring space is limited, as the angle of the measuring tool is difficult to adjust, further impacting work efficiency and measurement results.

[0003] Therefore, a new technology is needed to solve the problem that existing technologies make it inconvenient to accurately inspect and measure the dimensions of various mechanisms of the side doors of high-speed trains. Utility Model Content

[0004] To address the aforementioned problems in the prior art, this utility model provides a device for measuring the dimensions of the side doors of high-speed trains. It has a simple structure, is easy to use, facilitates the inspection and measurement of the dimensions of various mechanisms of the side doors of high-speed trains, improves inspection efficiency, and avoids the influence of operating angle or technique on the measurement results, making the measurement results more accurate.

[0005] The present invention adopts the following technical solution:

[0006] A device for measuring the side door dimensions of a high-speed train includes a measuring body and a first measuring block, a second measuring block, and a third measuring block arranged sequentially along the measuring body. The first measuring block and the third measuring block are respectively installed at both ends of the measuring body, and one end of the second measuring block is installed on the measuring body and is located close to the third measuring block.

[0007] The first measuring body includes a first segment and a second segment that are fixedly connected to each other. The end of the second segment away from the first segment is fixedly connected to the measuring body. The cross-sections of the first segment, the second segment, the second measuring block, and the third measuring block are all cylindrical structures. The diameter of the second segment is larger than the diameter of the first segment, and the diameters of the second measuring block and the second segment are smaller than the diameter of the third measuring block.

[0008] As a further improvement to the technical solution of this utility model, the measuring body is in the shape of a straight line along its length.

[0009] As a further improvement to the technical solution of this utility model, the axes of the first segment, the second segment, the second measuring block, and the third measuring block are all parallel to each other and perpendicular to the measuring body.

[0010] As a further improvement to the technical solution of this utility model, the diameter of the second segment is equal to the diameter of the second measuring block.

[0011] As a further improvement to the technical solution of this utility model, the diameter of the first segment is 1 mm, the diameter of the second segment and the second measuring block is 3 mm, and the diameter of the third measuring block is 6 mm.

[0012] As a further improvement to the technical solution of this utility model, the axes of the first segment, the second segment, the second measuring block, and the third measuring block are located in the same vertical plane, and the upper end of the measuring body is fixed to the lower end of the second segment, the lower end of the second measuring block, and the lower end of the third measuring block, respectively.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This device for measuring the dimensions of EMU side doors features three measuring blocks spaced apart on a single measuring body. The width of each measuring block can be adjusted according to the actual dimensions of the side door to be measured. The presence of measuring blocks of different sizes on the measuring body ensures measurement accuracy. During measurement, the corresponding measuring block is inserted into the area being measured. By checking whether blocks exceeding the dimensional range of the area can be inserted, it can be determined whether the dimensional range of the measured area meets the requirements. The measurement process is simple and allows for rapid measurement of whether the dimensions of the side door components are within the required range. This standardizes the operation and improves measurement efficiency compared to traditional methods. The device has a simple structure, is easy to use, and facilitates the inspection and measurement of the dimensions of various mechanisms on EMU side doors, improving inspection efficiency. Furthermore, the cross-sections of the first, second, second, and third measuring blocks are all circular, avoiding the influence of operating angles or techniques on the measurement results, resulting in more accurate measurements.

It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0024] Reference Figure 1 A device for measuring the dimensions of side doors of high-speed trains includes a measuring body 1 and a first measuring block 2, a second measuring block 3, and a third measuring block 4 arranged sequentially along the measuring body 1. The first measuring block 2 and the third measuring block 4 are respectively fixedly installed at both ends of the measuring body 1. One end of the second measuring block 3 is installed on the measuring body 1 and is positioned close to the third measuring block 4. The first measuring body 1 includes a first segment 21 and a second segment 22 fixedly connected to each other. The end of the second segment 22 away from the first segment 21 is fixedly connected to the measuring body 1. Along the length direction of the measuring body 1, the width of the second segment 22 is greater than the width of the first segment 21, and the widths of the second measuring block 3 and the second segment 22 are both smaller than the width of the third measuring block 4. The second segment 22, the second measuring block 3, and the third measuring block 4 can all be connected to the measuring body 1 by welding or threaded connection. When using threaded connection, the first measuring block 2, the second measuring block 3, and the third measuring block 4 of different sizes can be replaced according to the actual measuring object. At this time, the measuring body 1 is provided with threaded holes corresponding to the first measuring block 2, the second measuring block 3, and the third measuring block 4, and the second segment 22, the second measuring block 3, and the third measuring block 4 are provided with external threads.

[0025] This solution integrates the four measurement parts—the first segment 21, the second segment 22, the second measuring block 3, and the third measuring block 4—onto a single measuring body 1. Operators can hold the measuring body 1 and insert the corresponding measuring parts into the part being measured, which reduces measurement errors caused by human manipulation. The measurement method is more convenient and simple, and the measurement results are more accurate.

[0026] Specifically, the measuring body 1 is in a straight line along its length. The cross-sections of the first segment 21, the second segment 22, the second measuring block 3, and the third measuring block 4 are all circular. The axes of the first segment 21, the second segment 22, the second measuring block 3, and the third measuring block 4 are all parallel to each other and perpendicular to the measuring body 1. The first segment 21, the second segment 22, the second measuring block 3, and the third measuring block 4 are all cylindrical structures. When the operator uses the measuring device to measure, the cylindrical blocks can flexibly and quickly enter and exit the measured part, and can measure 360 ​​degrees without the need for angular alignment, avoiding the influence of operating angle or technique on the measurement results, thus making the measurement results more accurate. The outer surfaces of the first segment 21, the second segment 22, the second measuring block 3, and the third measuring block 4 are all marked with their corresponding diameter dimensions. The distance between the second segment 22 and the second measuring block 3, and the distance between the second measuring block 3 and the third measuring block 4, can be set according to the actual situation to avoid obstruction between adjacent parts during measurement.

[0027] Specifically, the end of the second segment 22 furthest from the third measuring block 4 is aligned with the end face of the measuring body 1, and the end of the third measuring block 4 furthest from the second segment 22 is aligned with the end face of the measuring body 1. The measuring body 1 has a scale corresponding to the maximum distance between the second measuring block 3 and the third measuring block 4. This maximum distance is the distance between the two sides of the second measuring block 3 and the third measuring block 4 that are furthest from each other. Alternatively, a scale can be set corresponding to the minimum distance between the second measuring block 3 and the third measuring block 4. This minimum distance is the distance between the two sides of the second measuring block 3 and the third measuring block 4 that are closest to each other. The specific vertical distance can be set according to the actual situation. If it is necessary to measure whether a larger dimension meets the requirements, the second measuring block 3 and the third measuring block 4 can be inserted into the part to be measured at the same time, or one of the second measuring block 3 and the third measuring block 4 can be inserted into the part to be measured. At the same time, observe the scale value and, in combination with the diameter of the second measuring block 3 and the third measuring block 4, determine whether the dimension of the measured part meets the requirements.

[0028] Specifically, depending on the actual measurement situation, the axes of the first segment 21, the second segment 22, the second measuring block 3, and the third measuring block 4 can be set to be located in the same vertical plane. In this case, the upper end of the measuring body 1 is fixed to the lower end of the second segment 22, the lower end of the second measuring block 3, and the lower end of the third measuring block 4, respectively. Alternatively, the axes of the second segment 22, the second measuring block 3, and the third measuring block 4 can be set to be located in mutually independent planes.

[0029] Specifically, the diameter of the second segment 22 is equal to the diameter of the second measuring block 3.

[0030] Specifically, the diameter of the first segment 21 is 1 mm, the diameters of the second segment 22 and the second measuring block 3 are both 3 mm, and the diameter of the third measuring block 4 is 6 mm. This device has three measuring dimensions. When measuring the dimensions of the side doors of high-speed trains, combined with the above-mentioned dimension settings, one device can measure the dimensions of multiple parts. Compared to using two hexagonal sockets to measure the same part, the device of this solution significantly improves work efficiency and is easy to carry.

[0031] The measuring body 1 can be held as a handle. When measuring the size of the side door component, the operator holds the measuring body 1 and inserts the corresponding cylindrical gauge blocks into the part to be measured. For example, when the required size of the part to be measured is 3mm-6mm, the second measuring block 3 with a diameter of 3mm is inserted into the part to be measured. If the 3mm cylindrical second measuring block 3 can pass through the part to be measured, then the third measuring block 4 with a diameter of 6mm is inserted into the part to be measured. If the 6mm cylindrical gauge block cannot pass through the part to be measured, it is considered that the size of the part to be measured meets the requirements.

[0032] Other aspects of the device for measuring the side door size of a high-speed train described in this utility model are found in the prior art and will not be repeated here.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
