Description

Technical Field

[0001] The present application relates to the field of flatness measuring devices, and in particular to a flatness measuring device for a railway passenger car suspension seat. Background Art

[0002] During the inspection or renovation of railway passenger car steel structures, it is necessary to inspect the flatness of each hanger itself and the overall flatness of each group of hangers for the battery boxes, sewage boxes, fuel tanks, small-power diesel generator sets, chargers, inverters and other under-vehicle equipment welded on the steel structure. If the flatness exceeds the limit, it needs to be adjusted to ensure that the gap between the box body lifting ears and the hangers on the steel structure does not exceed the limit after the under-vehicle equipment is installed, thereby ensuring the installation quality of the under-vehicle equipment.

[0003] Due to the different structures, forms and weights of the equipment under the vehicle, the number of hangers in each group is also different. For example, most of the external waste boxes are designed with 4 hangers (2 on each side of the first and second positions of the vehicle, and the four hangers have the same elevation, but the elevations of the hangers on the first and second positions are higher than the plane below the traction beam), the battery box and inverter power box are designed with 3 hangers (1 hanger at each end of the box and 1 hanger in the middle, the end hangers have the same elevation, and the middle hanger has a higher elevation than the end hangers), and the small-power diesel engine set is designed with 2 hangers (1 hanger at each end, with the same elevation). The flatness of the above-mentioned 4 hangers and 3 hanger structures cannot be measured using conventional templates. The steel structure frame must be leveled first, and then the height of each hanger must be measured and the height difference must be calculated to obtain the flatness of each hanger. The prerequisite for measuring with this method is to move the vehicle to a production position capable of lifting the vehicle. Towing and leveling the vehicle will add more than 60 minutes of labor costs, which will seriously restrict production efficiency.

[0004] The flatness measurement process of the prior art is:

[0005] (1) During the inspection or renovation of steel structures, use a crane or a crane to place the steel structure on a saddle. Use an infrared level or an optical level adjusted to a horizontal level. Use the side bearing or air spring seat plate (machined surface) on the steel structure as the reference surface. Use a crane or a crane to fine-tune the height of the steel structure until the steel structure is leveled. Pad the gap between the saddle and the steel structure, and then measure the height of each set of hangers in turn. Calculate the height difference of each set of hangers to obtain the flatness of each set of hangers.

[0006] (2) When inspecting and repairing under-vehicle equipment such as waste boxes and battery boxes, a large number of special templates with different structures and sizes must be specially made, or three corners of the under-vehicle equipment lifting ears must be leveled according to the steel structure frame leveling method, and the height difference between the fourth corner or the middle hanging seat and the first three corners must be measured to obtain the flatness of each set of lifting ears.

[0007] The disadvantages of the existing flatness measurement technology are:

[0008] (1) During the steel structure maintenance process, four cranes or two cranes are needed to level the steel structure. Each steel structure hanger maintenance station needs to be equipped with the above equipment resources or the vehicle needs to be frequently reversed and towed to a station with the above equipment resources before the conditions for lifting the vehicle are met. The equipment investment cost is high and there are too many ineffective towing times.

[0009] (2) The conditions for setting up a steel structure truck are met. From setting up the truck to completing the leveling, 3 to 5 operators are required to work simultaneously for at least 60 minutes. Measuring the flatness of each set of suspension seats requires 2 people to work together for about 5 minutes. This is time-consuming and labor-intensive, which seriously restricts the factory's production rhythm and efficiency.

[0010] (3) The overall transformation cycle is short if the vehicle is not modified in conjunction with the repair process. During the steel structure modification process, some vehicles only have their chassis steel structure modified, and the modification cycle is about 1 day. For example, if a sewage tank hanger is welded to the chassis of a modified vehicle, the flatness of the sewage tank hanger of the modified vehicle is measured by leveling the vehicle, which will seriously affect the overall production progress.

[0011] (4) During the maintenance process of the under-vehicle equipment, the leveling lug method is used. Each device requires 2 to 3 people to work at the same time for at least 15 minutes, which is time-consuming and labor-intensive. If a special template is made, a large number of special templates need to be made according to different sizes, which adds a lot of extra costs. Utility Model Content

[0012] The purpose of this application is to provide a railway passenger car seat flatness measuring device, which eliminates the car leveling process, reduces the investment in large equipment resources such as car lifting machines and cranes, reduces frequent car pulling, and reduces operation time; it also eliminates the production of special templates or leveling box body lifting ears, reduces manufacturing cost investment, and reduces operation time.

[0013] In order to achieve the above objectives, this application provides the following technical solutions:

[0014] A device for measuring the flatness of a hanging seat of a railway passenger car comprises a first positioning ruler, a second positioning ruler, a third positioning ruler, a fourth positioning ruler and a laser transmitter, wherein the upper ends of the first positioning ruler, the second positioning ruler, the third positioning ruler and the fourth positioning ruler are respectively provided with magnetic devices, and the first positioning ruler, the second positioning ruler, the third positioning ruler and the fourth positioning ruler are respectively mounted on the bottom of the hanging seat through the magnetic devices, and the laser transmitter is mounted on the fourth positioning ruler, and the laser line emitted by the laser transmitter can coincide with the "0" engraved line of the first positioning ruler and the "0" engraved line of the second positioning ruler, and then the distance between the laser point of the laser line on the third positioning ruler and the "0" engraved line of the third positioning ruler is read, and the distance is the flatness of the hanging seat.

[0015] Furthermore, the laser emitter radiates a horizontal angle of 0° to 150°.

[0016] Furthermore, the laser emitter radiates at a horizontal angle of 110°.

[0017] Furthermore, the laser emitter can be adjusted arbitrarily in three-dimensional directions.

[0018] The beneficial effects of this application are:

[0019] (1) This application uses a magnetic device to install the positioning ruler at the bottom of the suspension base, which can quickly fix the measuring equipment without complicated installation steps. The use of a laser transmitter enables the laser line to quickly coincide with the "0" mark of the positioning ruler, simplifying the measurement process and improving measurement efficiency.

[0020] (2) The laser line emitted by the laser transmitter has high precision and high stability, and can provide accurate measurement data. By reading the distance between the laser point and the "0" mark on the third positioning ruler, the flatness of the hanger can be accurately calculated.

[0021] (3) Compared with traditional measurement methods, this device can significantly reduce manpower input. Traditional measurement methods may require multiple people to operate at the same time, while this device only requires one person to complete the measurement, reducing labor costs.

[0022] (4) Since the positioning ruler is installed by a magnetic device, it can be easily adapted to different sizes and shapes of suspension mounts. In addition, the installation position of the laser transmitter can also be adjusted as needed to meet different measurement requirements.

[0023] (5) By quickly and accurately measuring the flatness of the hanger, problems can be discovered and repaired in a timely manner, avoiding production delays and quality problems caused by unqualified hanger flatness, thereby improving production efficiency.

[0024] (6) However, compared with the multiple cranes or cranes required in traditional methods, the equipment cost is relatively low. In addition, the overall cost can be further reduced due to the reduction of manpower input and the improvement of production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The terms used in the implementation method part of this application are only used to explain the specific embodiments of this application, and are not intended to limit this application. The implementation method of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0030] like Figure 1 and Figure 2 As shown, a device for measuring the flatness of a railway passenger car suspension seat a comprises a first positioning ruler 1, a second positioning ruler 2, a third positioning ruler 3, a fourth positioning ruler 4 and a laser transmitter 5;

[0031] The first positioning ruler 1 extends from one side of the bottom of the hanging seat. The upper end of the ruler has a magnetic device 6 or other connecting structure such as bolts, nuts, etc., which is tightly attached to the bottom of the hanging seat. There is an obvious "0" mark on the left edge of the ruler.

[0032] The second positioning ruler 2 is installed at the other side of the bottom of the hanging seat at a certain angle (such as 90 degrees) with the first positioning ruler 1. The design of the ruler is the same as the first positioning ruler 1, and also has a magnetic device 6 and a "0" mark.

[0033] The third positioning ruler 3 is installed at the bottom of the suspension base at a certain angle with the first and second positioning rulers 2. The design of the ruler is the same as the first two.

[0034] Fourth positioning ruler 4: Parallel to the third positioning ruler 3 but located outside it, a laser emitter 5 is installed on the ruler. The laser emitter 5 has a switch and control button on the surface. The laser line emitted from the emitter is bright and stable.

[0035] Laser line: It is emitted from the laser emitter 5 and appears as a bright red thin line. The laser line precisely coincides with the “0” marks of the first and second positioning scales 2, and forms an obvious laser spot on the third positioning scale 3.

[0036] The laser line emitted by the laser transmitter 5 can coincide with the “0” line of the first positioning ruler 1 and the “0” line of the second positioning ruler 2, and then the distance between the laser point of the laser line on the third positioning ruler 3 and the “0” line of the third positioning ruler 3 is read, and this distance is the flatness H of the hanger.

[0037] In this embodiment, the laser transmitter radiates at a horizontal angle of 0° to 150°. For areas that need to be monitored or measured, a larger radiation angle means a wider coverage area. For example, in industrial automation, a laser transmitter can scan an entire production line without frequently moving or adjusting the equipment.

[0038] In this embodiment, the horizontal radiation angle of the laser transmitter is 110°.

[0039] In this embodiment, the laser emitter can be adjusted in three dimensions. The three-dimensional adjustment capability gives the laser emitter great flexibility, enabling it to adapt to various complex working environments and task requirements. Whether indoors or outdoors, whether on flat ground or rugged mountains, the laser emitter can find the best working state by adjusting the angle and direction.

[0040] The specific steps of measuring using the above-mentioned railway passenger car hanger seat flatness measuring device are as follows:

[0041] (1) Preparation stage:

[0042] Prepare the first positioning ruler 1 , the second positioning ruler 2 , the third positioning ruler 3 and the fourth positioning ruler 4 and ensure that they are in normal working conditions.

[0043] Check whether the power supply and laser line of the laser transmitter 5 are stable and clear.

[0044] Determine the position of the suspension base that needs to be measured, and clean the bottom of the suspension base to ensure that the magnetic suction device 6 can be firmly adsorbed.

[0045] (2) Install the positioning ruler:

[0046] The upper ends of the first positioning ruler 1, the second positioning ruler 2, the third positioning ruler 3 and the fourth positioning ruler 4 are respectively adsorbed at different positions on the bottom of the suspension base through the magnetic adsorption device 6. These positioning rulers should be placed according to a predetermined layout and angle to ensure that the laser line can accurately coincide with their "0" engraved lines.

[0047] (3) Adjust the laser transmitter 5:

[0048] The laser transmitter 5 is mounted on the fourth positioning ruler 4 , and the laser transmitter 5 is ensured to be stable.

[0049] Adjust the angle and direction of the laser emitter 5 so that the laser line can coincide with the "0" marks of the first positioning ruler 1 and the second positioning ruler 2. This may require some careful adjustments to ensure the accurate position of the laser line.

[0050] (4) Read data:

[0051] After the laser line is stabilized, observe the position of the laser line on the third positioning ruler 3. The position where the laser line intersects the third positioning ruler 3 is the laser point.

[0052] Use a measuring tool (such as a vernier caliper or electronic measuring ruler) to read the distance between the laser point and the "0" mark on the third positioning ruler 3. This distance is the flatness value of the hanger.

[0053] (5) Recording and analysis:

[0054] Record the measured flatness value and compare it with the preset standard value.

[0055] If the flatness value exceeds the standard range, it is necessary to further analyze the cause and take appropriate measures to repair or adjust it.

[0056] (6) Cleaning and finishing:

[0057] After the measurement is completed, the positioning ruler and the laser transmitter 5 are removed from the suspension base and kept properly.

[0058] Clean up your work area and make sure there are no leftover tools or debris.

[0059] Through the above steps, the flatness measuring device for railway passenger car hanger seat can be used to accurately measure the flatness of the hanger seat and provide important data support for subsequent inspection and maintenance.
