Description

Technical Field

[0001] The utility model relates to an electrical characteristic testing device, in particular to a portable railway ZD6 switch machine internal circuit electrical characteristic testing device. Background Art

[0002] Railway switch can reliably change the position of turnout, change the direction of turnout opening, and lock the turnout point rail. It is an important signal basic equipment that reflects the position of turnout. It can well ensure driving safety and improve transportation efficiency. With the continuous progress and rapid development of my country's railway industry, the railway mileage continues to increase, and the running speed of trains continues to increase. As the mainstream switch used in my country's railways, the number of ZD6 type switch machines is also growing synchronously. Therefore, the pre-online test of ZD6 type railway switch machines is extremely important. The contact degree of electrical contacts directly affects the operation status of railway switch machines, and then directly affects the safety and smoothness of transportation.

[0003] According to the requirements of the National Railway Group's documents "Regular Railway Signal Maintenance Rules and Business Management" (Tie Zong Yun

[2015] No. 238) and "High-speed Railway Signal Maintenance Rules and Business Management" (Tie Zong Yun

[2015] No. 322) and other regulatory documents, the ZD6 railway switch machine needs to be returned to the maintenance station for rotation maintenance after five years of operation. However, the ZD6 railway switch machine in use is replaced during construction on site. Therefore, the switch machine will be stored on site for a certain period of time. Due to the influence of storage time and environment, the electrical contact characteristics inside the switch machine will cause the resistance value to change, thus causing the switch machine to malfunction, causing construction delays or malfunctions, which will greatly interfere with the normal transportation of the railway. Usually on site, the electrical contacts inside the switch machine will be wiped before construction, and then the resistance value will be tested using an instrument, but it takes a lot of time.

[0004] Therefore, a new device for testing the electrical characteristics of the internal circuit of the railway ZD6 switch is needed to determine the contact condition of the electrical contacts of the ZD6 switch and test the wiped condition. This device needs to meet three conditions: 1. It can intuitively test the resistance of the electrical contacts of the specified circuit and can test in real time; 2. It can test multiple models of ZD6 railway switch machines; 3. It can change the existing workflow and greatly improve the existing testing, cleaning, and retesting workflow.

The electronic digital display module 1 is connected to the power module 2, and the digital display module 1 is connected to the compatible interface module 4 and the separate test port 6 through the switching unit 3.

[0024] It is worth noting that the electronic digital display module 1 is used to display the resistance of electrical contacts. The module adopts a high-precision resistance digital display meter. The signal is introduced by the switching unit and the power is provided by the power module.

[0025] It is worth noting that the power module 2 uses a 3200Mah lithium battery to power the electronic digital display module and the test module, and the power module can be charged using a microUSB.

[0026] It is worth noting that the switching unit 3 uses five three-state rocker switches to switch different circuits under different models.

[0027] It is worth noting that the compatible interface module 4 is based on the universal male plug of the ZD6 type switch machine as a prototype, and a circuit that can be directly inserted into the ZD6 switch machine is produced.

[0028] It is worth noting that the boat-shaped switch is used to control the input power supply. Pressing "○" starts the device working, and pressing "-" stops the device working.

[0029] It is worth noting that the separate test port 6 is equipped with a universal interface, which can be used to check one by one when the electrical contacts in a certain circuit are in poor contact.

[0030] In addition, the switch indicator light 7 uses an LED light as a switch indicator light to indicate that the device is in working state.

[0031] The working principle of this specific implementation is as follows Figure 2 As shown: Insert the power compatible interface module into the internal connector of the switch machine to test the interface and circuit connection. The switching unit uses 5 three-state rocker switches to switch different circuits under different models. The electronic digital display module uses a high-precision resistance digital display meter. The signal is introduced by the switching unit and the power module provides power. A 3200Mah lithium battery is used to power the electronic digital display module and the test module. The power module can be charged using microUSB. After the resistance test in the loop is completed, it is displayed in real time on the digital display module.

[0032] In addition, it is equipped with a universal interface, and the alligator clips provided can be used to check one by one if the electrical contacts in a certain circuit are in poor contact.

[0033] The method of using this specific implementation is as follows:

[0034] 1. Press the rocker switch to start the device. The red working indicator light indicates normal operation. Insert the wiring terminal to short-circuit and check whether it is reset to zero. Release it to check whether there is no reading. If all are correct, the device is normal.

[0035] 2. Insert the device into the internal connector of the switch machine to be tested, and select the specified circuit to be tested through the rocker switch. At this time, the resistance reading will be displayed on the resistance meter. In principle, the reading should be 0Ω. If not, wipe the electrical contacts one by one until the reading returns to zero;

[0036] 3. There are 5 rocker switches in total, and each has three states. If not specified, the other rocker switches should be placed in the middle. The following takes position 1 and 3 closed as an example:

[0037] ① The starting circuit uses A↑ and B↑ as positioning start, and A↑ and B↓ as positioning start;

[0038] ② Single-action single-machine positioning is represented by A↓, B↑, and reverse position is represented by A↓, B↓;

[0039] ③ Single-action double-machine E machine, single-action double-machine J machine, double-action single machine one-action, two-action, double-action double machine two-action E positioning is represented by A↓, B↑, C↑, and reverse position is represented by A↓, B↓, C↑;

[0040] ④ Double-action double-machine and one-action E-machine, the positioning is represented by A↓, B↑, E↑, and the reverse position is represented by A↓, B↑, F↑;

[0041] ⑤ Double-acting double-machine and one-acting J machine, the positioning is represented by A↓, C↓, E↑, and the reverse position is represented by A↓, C↓, F↑;

[0043] 4. When it is determined which circuit has the problem, the electrical contacts can be wiped and checked. If the result is not obvious, all the rocker switches can be placed in the middle state, and the alligator clamps can be used to test the electrical contacts on the circuit one by one until the electrical contacts with poor contact are found.

[0044] The device for testing the electrical characteristics of the internal circuit of the railway ZD6 type switch machine in this specific implementation is simple, practical, and efficient. Maintenance-free is the outstanding advantage of the tester. The size is: length 20㎜*width 15㎜*height 20㎜, and the weight is about 500g. Before the switch machine is put into operation, the contact condition of the electrical contacts of the internal circuit of the switch machine can be tested without electricity, which solves the problem of being unable to power on the test and needing to use an instrument to test the electrical contacts one by one. At the same time, the device realizes online testing, and can observe the change of resistance in real time while cleaning the electrical contacts, making the cleaning more significant. In addition, a rocker switch is designed for dialing to meet the testing requirements of various models of ZD6 type railway switch machines.
