Description

Technical Field

[0001] This invention belongs to the field of railway signaling technology, specifically relating to a wiring method for a ZD6 type switch machine used for testing and experimentation. Background Technology

[0002] The ZD6 type switch machine is a simple, reliable, and widely used switch machine that is popular in the field. However, this type of switch machine needs to be repaired every 2-3 years, and the signal maintenance stations of various railway signaling sections undertake a large number of such repair tasks every year. Each switch machine must undergo electrical performance testing before leaving the station. In the past, the requirements for this test were not high, and the circuit was simple. The tests conducted by the signal maintenance stations of various railway signaling sections could basically meet the needs of the field. With the continuous development of railway transportation, the electrical performance testing of switch machines before and after leaving the station has become increasingly important and has become one of the means for railway signaling sections to control the quality of switch machine operation. Railway signaling sections have been continuously improving this method.

[0003] In recent years, the ZD6 type switch machine has been used in a variety of ways: traditional single-machine traction, as well as double-machine and triple-machine traction; some switch machines are used as single-movement machines, while others are used as double-movement, triple-movement, intermediate-movement, or final-movement machines. Each usage method has slight differences in the circuit connection. In railway yards, these differences are covered by specific circuit designs, eliminating usage issues. However, during maintenance, various types and usage methods of switch machines require performance testing within the repair shop. This necessitates that the repair shop's test benches be able to test multiple switch machines with different circuits for different usage methods, posing a challenge to switch machine testing. Some repair shops, unable to meet the testing needs of all types of switch machines with a single test bench, have to equip themselves with test benches suitable for their specific equipment types. Other repair shops, with multiple equipment types, often require more than one test bench. Currently, the best-case scenario is that some repair shops can perform testing on a single test bench, but they still need to equip themselves with multiple connecting cables depending on the equipment type and usage method. These connecting cables are commonly known as "sub-wires." The sub-wire is a section of wire connecting the cable box to the internal terminals of the switch machine. Its main function is to drive the switch machine motor to achieve forward and reverse rotation, and to indicate the switch machine's positioning and reverse positions. The number of its core wires and the purpose of each core wire are predetermined; that is, this section of wire is part of the turnout's standard circuit and cannot be changed. When testing a switch machine, the sub-wires of the original switch machines of different types must be removed and replaced with the sub-wire of the switch machine to be tested. Replacing the sub-wire is a manual operation, which is inefficient and unsafe. Therefore, railway signaling departments and on-site maintenance personnel urgently need to address this issue. There is a strong desire for a new method to test different switch machines with minimal or no wiring changes; to allow switching from testing one type of switch machine to another without moving the test bench, reducing intermediate operations, improving safety, and increasing efficiency. This invention studies various usage scenarios of the ZD6 switch machine, analyzes and summarizes various circuit types, and achieves the goal of testing ZD6 switch machines with different wiring configurations on a single test bench without wiring changes by disconnecting or connecting individual core wires on the plug side of the sub-line connector, thus meeting the needs of the field. Summary of the Invention

[0004] The purpose of this invention is to provide a wiring method for testing ZD6 type switch machines, so that when testing different ZD6 type switch machines, only one sub-wire is used, and different ZD6 type switch machines can be tested without changing the wire; this reduces intermediate operation steps, improves safety, improves work efficiency, and meets the requirements of field use.

[0005] The objective of this invention is achieved as follows: It relates to a wiring method for testing a ZD6 type switch machine, characterized by comprising: a ZD6 type switch machine test cable box and terminals within the cable box; X1, X2, X3, and X4 connecting wires connected to the switch machine pin box CJQ; the switch machine pin box CJQ contains 13 terminals; the X1, X2, X3, and X4 connecting wires electrically connect the cable box to the switch machine circuit through the 13 terminals, for testing various types of ZD6 type switch machines.

[0006] The different types of ZD6 switch machines mentioned above are either traditional single-machine traction ZD6 switch machines, or ZD6 switch machines with double or triple traction, or ZD6 switch machines used for one-way, two-way, intermediate, or final movement.

[0007] The 13 terminals are numbered as follows: Terminal 1, Terminal 2, Terminal 3, Terminal 4, Terminal 5, Terminal 7, Terminal 8, Terminal 9, Terminal 10, Terminal 11, Terminal 12, Terminal 13, and Terminal 14.

[0008] The bridging between the terminals within the CJQ box of the switch machine, as well as their disconnection and grouping, are combined on the CJQ plug.

[0009] Terminals 1, 2, and 3 are electrically connected to connecting lines X1, X2, and X3, respectively; terminal 5 is electrically connected to connecting line X4; and terminals 7, 8, 9, and 10 are short-circuited; terminals 3 and 4 are short-circuited; terminal 1 is short-circuited to terminals 11 and 13, respectively; and terminal 2 is short-circuited to terminals 12 and 14, respectively.

[0010] All the numerical symbols within the CJQ box of the cable box and switch machine pin box are existing terminal symbols inside the equipment.

[0011] The switch machine pin box CJQ frame contains a positioning action circuit with terminals 1 and 5, and a positioning indication circuit with terminals 1 and 3. Terminal 1 is the common line for action and indication.

[0012] Terminals 2 and 5 are used as the reverse position operation circuit, and terminals 2 and 3 are used as the reverse position indication circuit. Terminal 2 is the common line for operation and indication. Terminals 9 and 10 short-circuit the diodes at the switch machine end.

[0013] The advantages of this invention are: While maintaining the original internal components and wiring of various ZD6 type switch machines, and keeping the number and wire number of the output cores from the original cable box unchanged, this invention modifies a section of the connecting wire from the cable box to the internal terminals of the switch machine. This connecting wire, commonly known as the "handle wire," is differentiated according to different circuit types inside the plug-in connector at one end of the handle wire switch machine. A jumper wire is added between some terminals. When different types of ZD6 type switch machines are connected to the test bench through this handle wire, they can independently construct their own operation and indication circuits, achieving electrical performance testing. This allows for testing different ZD6 type switch machines using only one handle wire without changing the wiring. It reduces intermediate operation steps, improves safety, increases work efficiency, and meets the requirements of on-site use.

[0014] This invention facilitates the standardization of various wiring configurations for different types of ZD6 switch machines using a single method. By using a single wire, various types of ZD6 switch machines can be tested, eliminating the need to change wire bundles for different ZD6 switch machines during testing. This reduces labor intensity, improves testing efficiency, and avoids the process of frequently disassembling and replacing different wire bundles when testing different types of ZD6 switch machines, thus avoiding the problems of being prone to errors and inefficient.

[0026] To further illustrate the technical means adopted by the present invention to achieve its intended purpose, the specific implementation methods, structural features and effects of the present invention are described in detail below with reference to the accompanying drawings and embodiments.

[0027] Example and Application 1

[0028] like Figure 1 and Figure 2 As shown, this invention relates to a wiring method for a ZD6 type switch machine used for testing, including: a ZD6 type switch machine test cable box 15 and various terminals within the cable box 15; X1, X2, X3, and X4 connecting wires and a switch machine plug box CJQ16; the switch machine plug box CJQ16 has 13 terminals, which are respectively numbered as: terminal 1, terminal 2, terminal 3, terminal 4, terminal 5, terminal 7, terminal 8, terminal 9, terminal 10, terminal 11, terminal 12, terminal 13, and terminal 14; the X1, X2, X3, and X4 connecting wires electrically connect the cable box 15 to the switch machine circuit through the 13 terminals; the bridging between the terminals within the switch machine plug box CJQ16, as well as their disconnection and grouping, are combined on the CJQ plug.

[0029] Terminal 1, terminal 2, and terminal 3 are electrically connected to the X1, X2, and X3 connecting lines respectively. Terminal 5 is electrically connected to the X4 connecting line. Terminals 7, 8, 9, and 10 are short-circuited respectively. Terminals 3 and 4 are short-circuited. Terminal 1 is short-circuited to terminal 11 and terminal 13 respectively. Terminal 2 is short-circuited to terminal 12 and terminal 14 respectively.

[0030] All wire numbers and terminal symbols within the cable box 1 and the switch machine pin box CJQ16 are the original wire numbers and terminal symbols inside the equipment. Within the switch machine pin box CJQ16, terminal 1 and terminal 5 are used as positioning action circuits, and terminal 1 and terminal 3 are used as positioning indication circuits. Terminal 1 is the common line for action and indication.

[0031] Terminal 2 and terminal 5 are used as the reverse position operation circuit, and terminal 2 and terminal 3 are used as the reverse position indication circuit. Terminal 2 is the common line for operation and indication. Terminal 9 and terminal 10 short-circuit the diode at the switch machine end.

[0032] like Figure 2 As shown, on the CJQ socket of the switch machine, terminal 1 is the common line for positioning action and positioning indication; terminal 2 is the common line for reversing action and reversing indication; terminal 3 is the return line for positioning indication; terminal 4 is the return line for reversing indication; terminals 3 and 4 are connected together; terminal 5 is the common return line for positioning and reversing actions; terminals 7, 10, and 11 are connected together; terminals 12, 8, and 9 are connected together; by adding terminals 11 and 12 to the CJQ plug, terminals 7, 10, and 11 are connected together; terminals 12, 8, and 9 are connected together, thus forming the test circuit for the ZD6 type ordinary single-unit switch machine.

[0033] Example and Application of Example 2

[0034] as follows Figure 3 As shown, unlike Application 1, the dual-machine traction turnout circuit includes A-machine switch machine and B-machine switch machine;

[0035] A-type switch machine: On the CJQ socket of the switch machine, terminal 1 is the common line for positioning action and positioning indication; terminal 2 is the common line for reversing action and reversing indication; terminal 3 is the return line for positioning indication; terminal 4 is the return line for reversing indication; terminals 3 and 4 are connected together; terminal 5 is the common return line for positioning and reversing actions; on the CJQ plug, terminals 7, 8, 9, and 10 are connected together to form the test circuit for the ZD6 dual-machine A-type switch machine.

[0036] B-type switch machine: On the CJQ socket of the switch machine, terminal 1 is the positioning action line, terminal 2 is the reversing action line, terminal 5 is the shared return line for positioning and reversing actions, terminal 13 is the positioning indication line, terminal 14 is the reversing indication line, terminal 3 is the positioning indication return line, and terminal 4 is the reversing indication return line. Terminal 1 and terminal 13 are connected together, terminal 2 and terminal 14 are connected together, and terminal 3 and terminal 4 are connected together. Terminals 7, 8, 9, 10, 11, and 12 are bridging each other. Although terminals 1 and 2 are connected at this time, the switch machine can only indicate one position at a time. When the switch machine is in the positioning position, it does not move when the operation is to the positioning position, and it only moves when the operation is to the reverse position. When the switch machine is in the reverse position, it does not move when the operation is to the reverse position, and it only moves when the operation is to the positioning position. Therefore, connecting terminals 1 and 2 does not affect the test circuit, thus forming the ZD6 dual-machine B-type switch machine test circuit.

[0037] Example and Application of Example 3

[0038] as follows Figure 4 As shown, when the ZD6 switch machine is used as a double-action turnout in two-action mode and in stand-alone operation, its circuit is as follows: Figure 4 As shown, on the CJQ socket of the switch machine, terminal 1 is the common line for positioning action and positioning indication, terminal 2 is the common line for reversing action and reversing indication, terminal 3 is the return line for positioning indication, terminal 4 is the return line for reversing indication, terminal 3 and terminal 4 are bridging, terminal 5 is the common return line for positioning and reversing actions, and terminal 7, terminal 10, terminal 11, terminal 12, terminal 8, and terminal 9 are bridging, which constitutes the switch machine test circuit for the ZD6 switch machine used as a two-action turnout single machine.

[0039] Example and Application of Example 4

[0040] This invention applies to the second-action double-start turnout of a double-start turnout. When the ZD6 switch machine is used as the second-action double-start turnout and both machines are in operation, its circuit is as follows: Figure 5 As shown, it includes:

[0041] A-type switch machine

[0042] On the CJQ plug of the switch machine, terminal 1 is the common line for positioning action and positioning indication, terminal 2 is the common line for reversing action and reversing indication, terminal 3 is the return line for positioning indication, terminal 4 is the return line for reversing indication, terminal 3 and terminal 4 are bridging, terminal 5 is the common return line for positioning and reversing actions, and terminal 7, terminal 8, terminal 9, and terminal 10 are bridging, which constitutes the switch machine test circuit of machine A when the ZD6 switch machine is used as a double-action turnout with two-action double machines.

[0043] B-type switch machine

[0044] On the CJQ socket of the switch machine, terminal 1 is the outgoing line for positioning action, terminal 2 is the outgoing line for reversing action, terminal 5 is the shared return line for positioning and reversing actions, terminal 13 is the outgoing line for positioning indication, terminal 14 is the outgoing line for reversing indication, terminal 3 is the return line for positioning indication, and terminal 4 is the return line for reversing indication. Terminals 1 and 13 are bridging each other, as are terminal 2 and 14, and terminal 3 and 4. Terminals 7, 8, 9, 10, 11, and 12 are bridging each other. Although terminals 1 and 2 are connected, the switch machine can only indicate one position at a time. When the switch machine is in the positioning position, it does not move when the operation is to the positioning position, and it only moves when the operation is to the reverse position. When the switch machine is in the reverse position, it does not move when the operation is to the reverse position, and it only moves when the operation is to the positioning position. Therefore, connecting terminals 1 and 2 does not affect the test circuit, and constitutes the switch machine test circuit of machine B when the ZD6 switch machine is used as a double-action turnout with two-action double machines.

[0045] Example 5 and its application

[0046] When the ZD6 switch machine is used as one of the two movements of a double-action turnout, and both machines are in operation, its circuit is as follows: Figure 6 As shown:

[0047] Also includes: A-type switch machine

[0048] On the CJQ socket of the switch machine, terminal 1 is the common line for positioning action and positioning indication; terminal 2 is the common line for reversing action and reversing indication; terminal 3 is the return line for positioning indication; terminal 4 is the return line for reversing indication; terminals 3 and 4 are bridging; terminal 5 is the common return line for positioning and reversing actions; terminals 7, 8, 9, and 10 are bridging; at this time, terminals 13, 14, 15, and 16 are non-test contacts and are not considered during testing. This constitutes the test circuit for switch machine A when the ZD6 switch machine is used as a double-action turnout.

[0049] B-type switch machine

[0050] On the CJQ socket of the switch machine, terminal 1 is the positioning action line, terminal 2 is the reversing action line, terminal 11 is the positioning indication line, terminal 12 is the reversing indication line, terminal 11 and terminal 1 are connected together, terminal 12 and terminal 2 are connected together, terminal 3 is the positioning indication return line, terminal 4 is the reversing indication return line, terminal 3 and terminal 4 are connected together, terminal 5 is the shared return line for positioning and reversing actions, and terminal 7, terminal 8, terminal 9, and terminal 10 are connected together. At this time, terminal 13, terminal 14, terminal 15, and terminal 16 are non-test contacts and are not considered during testing. This constitutes the test circuit of the ZD6 switch machine used as a double-action turnout, and the B switch machine when both machines are used.

[0051] Example 6 and its application

[0052] When the ZD6 switch machine is used as a three-way turnout, such as Figure 7 As shown, the circuit of the first-moving switch machine is the same as the circuit of the double-machine traction turnout B machine in the second case mentioned above when terminals 7, 8, 9, and 10 are connected across each other.

[0053] The circuit of the intermediate-moving switch machine is the same as the single-moving turnout circuit in the first case mentioned above when terminals 3, 4, 7, 8, 9, and 10 are connected across each other.

[0054] The circuit of the last-moving switch machine is the same as the single-moving circuit of the double-moving turnout in the third case mentioned above when terminals 3, 4, 7, 8, 9, and 10 are connected across each other; therefore, these three circuits will not be discussed here.

[0055] Example and Application of Example 7

[0056] When the ZD6 switch machine is used as a three-way turnout, the application circuit for the first and second movements is set up as a single machine, such as... Figure 8 As shown:

[0057] In this application, when terminals 3, 4, 7, 8, 9, and 10 are bridging, the circuit is the same as the single-action turnout circuit in the first case mentioned above. Terminals 13 and 14 in the cable box and their wiring are non-characteristic test wires and are not considered here.

[0058] Implementation Examples and Applications of Implementation Examples 8

[0059] When the ZD6 switch machine is used as a three-way turnout, with the third way configured as a double machine, such as Figure 9 As shown, the circuit of the third moving A-type switch machine is the same as the circuit of the A-type switch machine in the second case when terminals 3, 4, 7, 8, 9, and 10 are bridging. The circuit of the third moving B-type switch machine is the same as the circuit of the B-type switch machine in the second case when terminals 3, 4, 7, 8, 9, and 10 are bridging.

[0060] The above basically covers the wiring of the main types of ZD6 switch machines. It is evident that the method of this invention can meet the testing needs of various types of ZD6 switch machines. When wiring, one end is equipped with a switch machine plug box CJQ16, and the other end is marked with a terminal number. Plug in the end with the CJQ marking, and connect the end with the wire number to the switch machine terminal according to the wire number. When testing switch machines with different wiring, only the switch machine needs to be changed, not the wire harness. That is, multiple ZD6 switch machines can be tested on the same harness wire, improving production efficiency, reducing labor intensity, and facilitating on-site operation. It is a practical wiring method welcomed by the field.

[0061] It should be noted that the numerical symbols within the boxes of cable box 15 and switch machine pin box CJQ16 in this invention correspond to the symbols within the equipment and materials.

[0062] Furthermore, the output end of the switch test bench of the wiring method of the present invention is sometimes expressed as a cable box 15, but is not limited to being expressed as a cable box 15; the circuit constructed by this wiring method also includes the ability to switch from testing a ZD6 type switch to testing a ZD7 type fast switch on this test bench without changing the wiring, only changing the switch. This functional right is also protected.

[0063] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
