[0002] The axle temperature detection device on the running gear of the electric locomotive is a component of the running gear of the electric locomotive for detecting key data such as temperature and vibration of equipment on the bogie of the locomotive. The axle temperature detection device mainly monitors temperature and vibration of key information through six point probes on each axle box, axle holder and traction motor on each side of the bogie of the SS4B electric locomotive, the SS4 electric locomotive and the HXD1 electric locomotive, to determine and alarm whether a fault such as excessively high temperature and excessively large vibration occurs during normal operation of the locomotive, so as to avoid the locomotive from breaking down due to faults such as burning axle, cutting axle and motor bearing seizure caused by excessively high temperature during operation, thereby causing huge losses.

[0003] When the SS4B electric locomotive, the SS4 electric locomotive and the HXD1 electric locomotive are overhauled according to the running distance, the focus is on disassembly and overhaul. The axle temperature detection device installed on the running gear of the electric locomotive needs to be overhauled by lifting the locomotive.

It is necessary to again lift the locomotive out of the bogie to an open area for further troubleshooting and maintenance. The use of more overhaul personnel, long working hours and large workload during the second overhaul bring a large amount of work to the overhaul operation, affecting safety and efficiency.

DETAILED DESCRIPTION

[0035] In order to make the above objectives, features and advantages of the present application more apparent, specific embodiments of the present application are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in a number of ways other than those described herein, and by persons skilled in the art without departing from the spirit and scope of the present application, and therefore the present application is not limited to the specific embodiments disclosed below.

[0036] In the description of the present application, it should be understood that if these terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the purpose of facilitating the description of the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0037] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0038] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0039] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact, or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0040] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0041] Understandably, the axle temperature detection device on the running gear of an electric locomotive is a component used to detect critical data such as temperature and vibration of equipment on the bogies. When an electric locomotive is disassembled for maintenance, the axle temperature detection devices installed on the running gear need to be inspected separately. Before maintenance, the axle temperature detection devices need to be removed and inspected separately. After maintenance, the components are reassembled onto the bogies.

[0042] Because there is no equipment to test the axle temperature testing and maintenance device, an electrical test is only conducted using the original equipment after the locomotive frame has been dismounted. If a fault is found in the axle temperature device on the bogie, personnel cannot access it for repair or replacement due to space limitations between the locomotive's upper underframe and the bogie. The locomotive must be dismounted again and the bogie moved to an open area for further troubleshooting and repair. This second repair requires more personnel, takes longer, and involves a greater workload, significantly impacting safety and efficiency.

[0043] For this purpose, please refer to Figure 1 to Figure 3 This application provides a test and maintenance device 100. Figure 1 This is a front view of a test and maintenance apparatus 100 according to an embodiment of this application. Figure 2 for Figure 1 The side view of the test and maintenance device 100 shown is shown. Figure 3 for Figure 1 The diagram shows a top view of the test and maintenance apparatus 100. This test and maintenance apparatus 100 is used to test and maintain the axle temperature detection device 300 on the running gear 200 of an electric locomotive.

[0044] To better illustrate the structure of the test and maintenance device 100 of this application, the structure of the traveling section 200 will be briefly described here. (See reference...) Figure 4 , Figure 4 This is a schematic diagram showing the interaction between the axle temperature detection device 300 and the traveling section 200. The traveling section 200 includes two bogies 210, each bogie 210 including two pairs of wheels 211, each pair of wheels 211 including an axle 2111, two wheelsets 2112, and a motor 2113. The two wheelsets 2112 are spaced apart from the axle 2111 along the axial direction of the axle 2111, and the motor 2113 is mounted on the axle 2111.

[0045] Each axle temperature detection device 300 includes a junction box 320, multiple conductive wires 330, and six probes 310. Two of the six probes 310 are located on both sides of the axial direction of the motor 2113, and the remaining four probes 310 are respectively located on the axles 2111 on both sides of the axial direction of the wheelset 2112. The six probes 310 are electrically connected to the junction box 320 via the conductive wires 330. The probes 310 detect the temperature at their corresponding locations and transmit the data back to the junction box 320. It is understood that the junction box 320 is capable of acquiring and transmitting the data detected by the probes 310.

[0046] The feedback through the junction box 320 to the electric locomotive to monitor the temperature parameters and vibration parameters of the running gear 200 in real time, for judging and alarming whether the temperature is too high, the vibration is too large and other faults during the normal operation of the electric locomotive, avoiding the electric locomotive from causing the machine to break down and causing huge losses due to the high temperature, cut shaft, motor bearing seizure and other faults during the operation, so as to ensure the safety of the operation of the electric locomotive.

[0047] When the running gear 200 of the electric locomotive is disassembled for maintenance, the axle temperature detection device 300 of the running gear 200 needs to be removed for maintenance. After the maintenance of the axle temperature detection device 300 is completed, the axle temperature detection device 300 needs to be assembled on the running gear 200, and then the test and maintenance device 100 of the present application is used to perform a power-on test on the axle temperature detection device 300, and to troubleshoot and maintain in the case of failure.

[0048] In this way, the test and maintenance device 100 of the present application can perform live detection on the axle temperature detection device 300 on the disassembled running gear 200 to test the axle temperature detection device 300. When the axle temperature detection device 300 fails, troubleshooting and maintenance can be performed directly according to the detection parameters, without the need to disassemble the running gear 200 from the electric locomotive again, reducing the number of personnel required for maintenance, shortening the detection time, reducing the workload of maintenance, improving the efficiency of maintenance, and reducing safety hazards.

[0049] It is worth noting that the focus of the present application is on the test and maintenance device 100 and its application, and the specific structure of the running gear 200, the structure and working principle of the axle temperature detection device 300, the structure of the electric locomotive and the disassembly process are not the focus of the present application, which will not be described again in the following.

[0050] Referring to Figure 1 to Figure 3 In an embodiment, the test and maintenance device 100 includes a support structure 110 and a test host 120. The support structure 110 includes a support frame 111 having a plurality of placement cavities 1111, at least one placement cavity 1111 for storing maintenance tools during the test process, and a support platform 112 disposed on the top of the support frame 111 and capable of placing maintenance tools during the operation process. The test host 120 is disposed in the placement cavity 1111 of the support frame 111 and can be electrically connected to each probe 310 of the axle temperature detection device 300 for transmission connection.

[0051] The support structure 110 is a main frame of the test and maintenance device 100, and each component of the test and maintenance device 100 is supported and installed through the support structure 110. Moreover, the support structure 110 can integrate each component of the test and maintenance device 100 into a whole. In this way, the support structure 110 can drive each component of the test and maintenance device 100 to move to the vicinity of the walking part 200.

[0052] The test host 120 is a main component for testing and maintaining the axle temperature detection device 300. The test host 120 is used for testing device information display, function description, test information judgment and the like, and is arranged in the support structure 110. When the support structure 110 moves to the vicinity of the walking part 200, the test host 120 is electrically connected with each probe 310 of the axle temperature detection device 300 through the junction box 320. The junction box 320 can transmit the temperature and other parameters detected by each probe 310 to the test host 120.

[0053] After receiving the temperature and other parameters detected by each probe 310, the test host 120 can compare the parameters with preset parameters to perform a live test on each probe 310. For example, if the actual temperature parameter detected by a probe 310 is 0℃, but the preset temperature parameter of the probe 310 is 40℃, it indicates that the probe 310 is faulty and needs to be repaired or replaced.

[0054] At this time, the test host 120 can display the fault condition of the probe 310, and the maintenance personnel can replace or repair the probe 310 according to the fault information prompted by the test host 120. Of course, the test host 120 can also display other fault conditions of the probe 310. In this way, after the test host 120 is electrically connected with each probe 310 of the axle temperature detection device 300, whether each probe 310 is faulty can be detected, which facilitates troubleshooting and maintenance of the axle temperature detection device 300.

[0055] The test host 120 is a control host for troubleshooting the existing axle temperature detection device 300. The test host 120 can adopt the structure of a live test on the axle temperature detection device 300 in an electric locomotive. It is worth noting that the test host 120 is an existing device, and the principle of the test host 120 for live testing (fault detection) of the axle temperature detection device 300 is also an existing technology, which will not be described hereinafter.

[0056] Specifically, the support structure 110 includes a support frame 111 and a support platform 112. The support frame 111 is arranged along the height direction (Z direction) of the test and maintenance device 100. Figure 1The support platform 112 is arranged on the top of the support frame 111. The support frame 111 is the main frame of the support structure 110, and the support of various components of the test and maintenance device 100 is realized through the support frame 111.

[0057] Optionally, the support frame 111 is a frame structure. Of course, in other embodiments of the present application, the support frame 111 can also be a box structure. In an embodiment, the support frame 111 is a box-shaped cuboid. Of course, in other embodiments of the present application, the support frame 111 can also be a cube or other structural forms.

[0058] The support frame 111 has a plurality of placement cavities 1111. The inner part of the support frame 111 is partitioned to form a plurality of placement cavities 1111, and the test host 120 is placed in one of the placement cavities 1111, and at least one placement cavity 1111 can place a maintenance tool. The maintenance tool here refers to the tool used for troubleshooting and maintenance of the shaft temperature detection device 300. The maintenance tool here at least includes a screwdriver, a wrench, a multimeter, an inspection hammer, etc.

[0059] And the support platform 112 is also arranged on the top of the support frame 111, which can form a bearing surface on the top of the support frame 111, and the maintenance tool for maintenance work can be placed on the support platform 112. That is, in the actual maintenance process, the maintenance tool is taken out from the placement cavity 1111 of the support frame 111, and the maintenance tool can be placed on the support platform 112, and the maintenance personnel can take and place the maintenance tool on the support platform 112, which is convenient for the maintenance personnel to operate.

[0060] When the test and maintenance device 100 of the present application is used to carry out live test and maintenance on the shaft temperature detection device 300, the shaft temperature detection device 300 is installed at the corresponding position of the bogie 210 of the running part 200, the test and maintenance device 100 of the present application is moved to the vicinity of the running part 200, and the test host 120 is electrically connected with the junction box 320 of the shaft temperature detection device 300, so that the test host 120 is electrically connected with each probe 310 of the shaft temperature detection device 300.

[0061] The shaft temperature detection device 300 feeds back temperature parameters and the like to the test host 120 through the probe 310 and the junction box 320. The test host 120 performs a live test on each probe 310 of the shaft temperature detection device 300 according to the temperature parameters and the like to determine whether each probe 310 has a fault. When a certain temperature measurement probe 310 has a fault, the maintenance personnel directly take the maintenance tools on the support frame 111 and the support platform 112 to troubleshoot and maintain the probe 310. After troubleshooting or replacing the probe 310, the live test is performed on each probe 310 of the shaft temperature detection device 300 in the above manner until the temperature parameters of each probe 310 meet the requirements.

[0062] The test and maintenance device 100 of the present application performs a live test on the bogie 210 and the shaft temperature detection device 300 of the running gear 200 that is not assembled to the electric locomotive, that is, the present application can supply power for the operation of the shaft temperature detection device 300, and does not need to use the power supply system and control system of the electric locomotive to perform a live test on the shaft temperature detection device 300. When the shaft temperature detection device 300 has a fault, the shaft temperature detection device 300 can be troubleshooted and maintained in a larger space, avoiding the need to disassemble the running gear 200 from the electric locomotive again after the running gear 200 is assembled to the electric locomotive.

[0063] In this way, the test and maintenance device 100 of the present application can perform a live test on the shaft temperature detection device 300 on the disassembled running gear 200 to test the shaft temperature detection device 300. When the shaft temperature detection device 300 has a fault, the fault can be directly troubleshooted and maintained, without the need to disassemble the running gear 200 from the electric locomotive again, reducing the number of personnel required for maintenance, shortening the detection time, reducing the workload of maintenance, improving the efficiency of maintenance, and reducing safety hazards.

[0064] Referring to Figure 1 In an embodiment, the plurality of placement cavities 1111 are independently provided. That is, each placement cavity 1111 is not communicated with each other. In this way, when the test and maintenance device 100 moves to the vicinity of the running gear 200, the components in a certain placement cavity 1111 will not move to other placement cavities 1111, facilitating the maintenance personnel to take the maintenance tools or perform corresponding operations in the corresponding placement cavity 1111. Alternatively, the adjacent placement cavities 1111 are separated by a partition plate or the like.

[0065] Of course, in other embodiments of the present application, at least part of the placement cavities 1111 are communicated. That is, part of the placement cavities 1111 can be communicated, or all of the placement cavities 1111 can be communicated. In this way, the structure of the support frame 111 can be simplified, and the weight of the support frame 111 can be reduced.

[0066] Referring to Figure 1In an embodiment, each placement chamber 1111 is arranged in at least two rows and at least two columns. In the embodiment, there are four placement chambers 1111 arranged in two rows and two columns, and the four placement chambers 1111 respectively store the test host 120, the maintenance tools, and the power supply structure 130.

[0067] In Figure 1 the embodiment, the placement chambers 1111 are respectively a first storage chamber 1112, a second storage chamber 1113, a third storage chamber 1114, and a fourth storage chamber 1115. The first storage chamber 1112 is located at the upper left corner, the second storage chamber 1113 is located at the upper right corner, the third storage chamber 1114 is located at the lower left corner, and the fourth storage chamber 1115 is located at the lower right corner.

[0068] The test host 120 is installed in the first storage chamber 1112, the second storage chamber 1113 is a storage chamber for maintenance tools, and the second storage chamber 1113 can store tools used in the test process, such as screwdrivers, wrenches, and multimeters. The power supply structure 130 is installed in the third storage chamber 1114. The fourth storage chamber 1115 is also a storage chamber for maintenance tools, and the fourth storage chamber 1115 can store maintenance tools used in the test process, such as inspection hammers and connecting wires.

[0069] In other embodiments of the present application, each placement chamber 1111 can also be arranged in three rows and two columns, three rows and three columns, or the like. Of course, each placement chamber 1111 can also be arranged in one row or one column, as long as it can facilitate the storage of the test host 120, the power supply structure 130, and the maintenance tools.

[0070] Referring to Figure 1 and Figure 3 In an embodiment, the support structure 110 further includes a carrying platform 113, which is disposed on the front end face of the support frame 111. The carrying platform 113 is located below the support platform 112 and extends away from the support frame 111. The carrying platform 113 can store maintenance tools used in the test process.

[0071] In Figure 1 the direction shown, the left side of the support frame 111 is the front end face of the support frame 111. The carrying platform 113 is disposed on the front end face of the support frame 111 and extends away from the support frame 111. Moreover, the carrying platform 113 is located below the support platform 112. The carrying platform 113 can also store maintenance tools used in the test process.

[0072] It can be understood that in the actual test and maintenance process, the maintenance personnel can stand to test and maintain, at this time, the maintenance personnel can take and place the maintenance tools from the upper support platform 112. When the operator bends down or the lower end tests and maintains, the maintenance personnel can take and place the maintenance tools from the lower bearing platform 113. In this way, the maintenance personnel can operate conveniently.
