[0002] HXN5 diesel locomotive is one of the main passenger and freight diesel locomotives of China Railway. This locomotive uses AC transmission. The locomotive uses brake cylinders, TWK-100 pressure controllers and other components to achieve braking during parking braking, and the pressure standard is 620-660Kpa. TWK-100 pressure controller has A1-A2 terminals. When the pressure controller is activated, the A1-A2 terminals are in the normally open state. When the pressure controller is released, the A1-A2 terminals of the pressure controller are in the normally closed state.
[0003] At present, the parking brake pressure of the locomotive can be detected by the locomotive onboard safety and fire protection system (6A system), but the opening and closing status of the pressure controller cannot be detected. Utility Model Content
[0004] In view of the fact that the current locomotive parking brake pressure can detect the brake pressure value through the locomotive onboard safety and fire protection system (6A system), but cannot detect the opening and closing state of the pressure controller, this application proposes a device that can detect the opening and closing state of the pressure controller, and adopts the following technical solution.
[0005] A detection device for a parking brake pressure controller for a HXN5 locomotive includes a power supply, a coil, a rotating rod, a reset mechanism, a first connecting member, a second connecting member, an elastic deformation connecting member, a first indicator light, and a second indicator light. One end of the power supply is electrically connected to a terminal of the coil; the other end of the power supply and the other terminal of the coil are used to connect two terminals of a pressure controller. One end of the power supply is electrically connected to the elastic deformation connecting member; the other end of the power supply is electrically connected to the first indicator light and the second indicator light connected in parallel. The first indicator light is connected in series with the first connecting member; the second indicator light is connected in series with the second connecting member; the elastic deformation connecting member is arranged between the first connecting member and the second connecting member.

[0006] By adopting the above technical solution: when the two terminals of the pressure controller are in the normally open state, the coil does not attract the rotating rod, and the reset mechanism fixes the rotating rod, so that the rotating rod is not electrically connected to the elastic deformation connecting member by the first connecting member, and the first indicator light is on, indicating that the two terminals of the pressure controller are in the normally open state; when the two terminals of the pressure controller are in the normally closed state, the coil attracts the rotating rod, the rotating rod rotates, the rotating rod abuts against the elastic deformation connecting member, so that the elastic deformation connecting member is deformed, the second connecting member is electrically connected to the elastic deformation connecting member, and the second indicator light is on, indicating that the two terminals of the pressure controller are in the normally closed state. The above enables the device to detect the opening and closing state of the pressure controller. It should be pointed out that the attraction of the coil to the magnetic material after power is turned on is greater than the initial force of the reset mechanism.
[0007] A preferred embodiment of the HXN5 locomotive parking brake pressure controller detection device is that the first indicator light is a green light; and the second indicator light is a red light.
[0008] By adopting the above technical solution, the state of the pressure controller can be clearly indicated by the red light and the green light.

[0012] By adopting the above technical solution, the coil can more easily drive the rotating rod by attraction. If the reset mechanism and the coil are respectively located on the same side of the rotating rod, the coil attracts the rotating rod and needs to compress the reset mechanism, and one end of the reset mechanism is fixed. The reset mechanism arranged in this way is easy to block the rotation of the rotating rod.
[0013] A preferred embodiment of the HXN5 locomotive parking brake pressure controller detection device is that the reset mechanism includes a reset spring and a reset fixing seat; one end of the reset spring is connected to the reset fixing seat, and the other end is connected to the rotating rod.

[0020] By adopting the above technical solution, the elastic deformable connector can form a good electrical contact with the first connector, and the first conductive block and the middle conductive block do not interfere with the other end of the rotating rod inserted between the elastic deformable connector and the first connector.
[0021] A preferred embodiment of the HXN5 locomotive parking brake pressure controller detection device is that the second connecting member has a protruding second conductive block on the upper part of one side facing the elastic deformable connecting member; the elastic deformable connecting member has a protruding upper conductive block on the upper part of one side facing the second connecting member; when the two connecting terminals of the pressure controller are in a normally closed state, the elastic deformable connecting member is deformed so that the second conductive block is electrically connected to the upper conductive block, so that the second connecting member is electrically connected to the elastic deformable connecting member.
[0022] By adopting the above technical solution, the upper part of the elastic deformable connector is its maximum deformable position, and the upper conductive block is arranged on its upper part. The elastic deformable connector is deformed so that the second conductive block is electrically connected to the upper conductive block, so that the second connector can better form electrical contact with the elastic deformable connector.
[0023] A preferred embodiment of the HXN5 locomotive parking brake pressure controller detection device is that the HXN5 locomotive parking brake pressure controller detection device also includes a reinforced contact mechanism; the reinforced contact mechanism includes a reinforced fixing seat and a reinforced spring; the reinforced fixing seat is fixed on the mounting seat; one end of the reinforced spring is fixed on the reinforced fixing seat, and the other end is fixed on the elastic deformation connecting member; when the first connecting member is electrically connected to the elastic deformation connecting member, the reinforced spring is in an extended state.
[0024] By adopting the above technical solution, the contact strengthening mechanism strengthens the electrical contact effectiveness of the first connecting member and the elastic deformation connecting member, and reduces the probability of poor contact between the two.
[0025] In summary, the HXN5 type locomotive parking brake pressure controller detection device of the present application has the following beneficial effects:
[0026] When the two terminals of the pressure controller are in the normally open state, the coil does not attract the rotating rod, and the reset mechanism fixes the rotating rod, so that the rotating rod is not electrically connected to the elastic deformation connecting member by the first connecting member, and the first indicator light is on, indicating that the two terminals of the pressure controller are in the normally open state; when the two terminals of the pressure controller are in the normally closed state, the coil attracts the rotating rod, the rotating rod rotates, the rotating rod abuts against the elastic deformation connecting member, causing the elastic deformation connecting member to deform, the second connecting member is electrically connected to the elastic deformation connecting member, and the second indicator light is on, indicating that the two terminals of the pressure controller are in the normally closed state.

DETAILED DESCRIPTION
[0032] The HXN5 locomotive parking brake pressure controller detection device of the present application is described in detail below with reference to the accompanying drawings.
[0033] Please refer to Figure 1 A HXN5 type locomotive parking brake pressure controller detection device includes a power supply 1, a coil 2, a rotating rod 3, a reset mechanism 4, a first connecting member 5, a second connecting member 6, an elastic deformation connecting member 7, a first indicator light 8 and a second indicator light 9.
[0034] The power source 1 may be a DC12V power source, or may be a DC68V power source connected to a locomotive and stepped down to DC12V by a step-down coil 2 for power supply.
[0035] The first connecting member 5 , the second connecting member 6 and the elastic deformation connecting member 7 are all conductors.
[0036] In one of the loops, one end of the power supply 1 is electrically connected to one terminal of the coil 2, and the other end of the power supply 1 and the other terminal of the coil 2 are used to connect two terminals of the pressure controller 10, such as Figure 1 The A1 and A2 terminals.
[0037] In another circuit, one end of the power supply 1 is electrically connected to the elastic deformation connection member 7. The other end of the power supply 1 is electrically connected to the first indicator light 8 and the second indicator light 9 in parallel. The first indicator light 8 is connected in series to the first connection member 5. The second indicator light 9 is connected in series to the second connection member 6. The elastic deformation connection member 7 is arranged between the first connection member 5 and the second connection member 6. The rotating rod 3 has a rotating fulcrum 301. The reset mechanism 4 is connected to the rotating rod 3. One end of the rotating rod 3 has a magnetic material 302. The magnetic material 302 is located outside one end of the coil 2. The other end of the rotating rod 3 is located between the first connection member 5 and the elastic deformation connection member 7. When the two terminals of the pressure controller 10 are in the normally open state, the first connection member 5 is electrically connected to the elastic deformation connection member 7. When the two terminals of the pressure controller 10 are in the normally closed state, the other end of the rotating rod 3 abuts against the elastic deformation connection member 7, so that the elastic deformation connection member 7 is deformed and disconnected from the first connection member 5, and the deformed elastic deformation connection member 7 is electrically connected to the second connection member 6.
[0038] In the above-mentioned HXN5 locomotive parking brake pressure controller detection device, when the two terminals of the pressure controller 10 are in the normally open state, the coil 2 does not attract the rotating rod 3, and the reset mechanism 4 fixes the rotating rod 3, so that the rotating rod 3 is not electrically connected to the elastic deformation connecting member 7 by the first connecting member 5, and the first indicator light 8 is on, indicating that the two terminals of the pressure controller 10 are in the normally open state. When the two terminals of the pressure controller 10 are in the normally closed state, the coil 2 attracts the rotating rod 3, the rotating rod 3 rotates, and the rotating rod 3 abuts against the elastic deformation connecting member 7, so that the elastic deformation connecting member 7 is deformed, and the second connecting member 6 is electrically connected to the elastic deformation connecting member 7, and the second indicator light 9 is on, indicating that the two terminals of the pressure controller 10 are in the normally closed state. The above enables the device to detect the opening and closing state of the pressure controller 10. It should be pointed out that the attraction of the coil 2 to the magnetic material 302 after power is turned on is greater than the initial force of the reset mechanism 4.
[0039] The first indicator light 8 may be a green light, and the second indicator light 9 may be a red light. The state of the pressure controller 10 can be clearly indicated by using the red light and the green light.
[0040] The locomotive realizes braking during the parking brake process through brake cylinders, TWK-100 pressure controller 10 and other components. The pressure standard is 620-660Kpa. When the pressure controller 10 is activated, the A1-A2 terminals should be in the normally open state. When the pressure controller 10 is released, the A1-A2 terminals of the pressure controller should be in the normally closed state. The locomotive parking brake pressure controller detection device judges the state of the A1-A2 terminals of the pressure controller and displays it through the indicator light. The specific working process of the detection device is as follows: the HXN5 locomotive parking brake pressure controller detection device is connected to the A1 and A2 terminals of the pressure controller. When there is no pressure in the pressure controller 10, A1-A2 is in the normally closed state, the coil 2 is energized and the rotating rod 3 is attracted, and the red light is on. When the pressure in the pressure controller 10 reaches 620-660Kpa, the pressure controller 10 is activated, A1-A2 is in the normally open state, the coil 2 is de-energized and the rotating rod 3 is not attracted, and the green light is on. The device mainly determines whether the locomotive parking brake pressure value is within the specified range by detecting the normally open / normally closed state of the A1-A2 terminal of the TWK-100 pressure controller.
[0041] The magnetic material 302 may be an iron block or a nickel block. Both the iron block and the nickel block can be attracted by the coil 2 after being energized, so that the rotating rod 3 rotates.
[0042] The reset mechanism 4 and the coil 2 can be located on both sides of the rotating rod 3, respectively, and the coil 2 can more easily drive the rotating rod 3 by attraction. If the reset mechanism 4 and the coil 2 are located on the same side of the rotating rod 3, the coil 2 attracts the rotating rod 3 and needs to compress the reset mechanism 4, and one end of the reset mechanism 4 is fixed, so the reset mechanism 4 set in this way is easy to block the rotation of the rotating rod 3.
[0043] The reset mechanism 4 includes a reset spring 401 and a reset fixing seat 402. One end of the reset spring 401 is connected to the reset fixing seat 402, and the other end is connected to the rotating rod 3. The reset spring 401 can pull the rotating rod 3 to reset.
[0044] The rotating rod 3 may be an L-shaped rod, including two connected straight rods, and the rotating fulcrum 301 is located at the intersection of the two straight rods, so that the rotating distances of the two ends of the rotating rod 3 are controllable.
[0045] The HXN5 locomotive parking brake pressure controller detection device also includes a mounting seat 11, and one end of the first connecting member 5, one end of the second connecting member 6 and one end of the elastic deformation connecting member 7 are all fixed on the mounting seat 11, so that the elastic deformation connecting member 7 can be conveniently controlled to select the connection with the first connecting member 5 or the second connecting member 6.
[0046] Please refer to Figure 2 In order to enhance the contact conductive effect, a first conductive block 501 is provided in the middle of one side of the first connector 5 facing the elastic deformable connector 7. A middle conductive block 701 is provided in the middle of one side of the elastic deformable connector 7 facing the first connector 5. When the two terminals of the pressure controller 10 are in the normally open state, the first conductive block 501 is electrically connected to the middle conductive block 701, so that the first connector 5 is electrically connected to the elastic deformable connector 7. The elastic deformable connector 7 can form a good electrical contact with the first connector 5, and the first conductive block 501 and the middle conductive block 701 do not interfere with the other end of the rotating rod 3 inserted between the elastic deformable connector 7 and the first connector 5.
[0047] Please refer to Figure 2 , also in order to enhance the contact conductive effect, the second connector 6 has a protruding second conductive block 601 on the upper part of one side facing the elastic deformable connector 7. The elastic deformable connector 7 has a protruding upper conductive block 702 on the upper part of one side facing the second connector 6. When the two terminals of the pressure controller 10 are in the normally closed state, the elastic deformable connector 7 is deformed so that the second conductive block 601 is electrically connected to the upper conductive block 702, so that the second connector 6 is electrically connected to the elastic deformable connector 7. The upper part of the elastic deformable connector 7 is its maximum deformable position, and the upper conductive block 702 is arranged on its upper part. The elastic deformable connector 7 is deformed so that the second conductive block 601 is electrically connected to the upper conductive block 702, so that the second connector 6 is better in electrical contact with the elastic deformable connector 7.
[0048] Please refer to Figure 3 In order to reduce the occurrence of poor contact between the first connecting member 5 and the elastic deformation connecting member 7, the HXN5 type locomotive parking brake pressure controller detection device is designed to also include a reinforced contact mechanism 12. The reinforced contact mechanism 12 includes a reinforced fixing seat 1201 and two reinforced springs 1202. The reinforced fixing seat 1201 is fixed on the mounting seat 11. Please refer to Figure 4One end of each reinforcing spring 1202 is fixed on the reinforcing fixing seat 1201, and the other end is fixed on the elastic deformation connecting member 7. Two reinforcing springs 1202 are arranged on both sides of the reinforcing fixing seat 1201 and both sides of the elastic deformation connecting member 7. When the first connecting member 5 is electrically connected to the elastic deformation connecting member 7, the reinforcing spring 1202 is in an extended state. The reinforcing contact mechanism 12 strengthens the electrical contact effectiveness of the first connecting member 5 and the elastic deformation connecting member 7, and reduces the probability of poor contact between the two.
[0049] The device can be encapsulated as a whole in a housing, exposing two contact points, namely, the other end of the power supply 1 and the other terminal of the coil 2, for connecting two terminal blocks of the pressure controller 10.
[0050] The coil 2, rotating rod 3, reset mechanism 4, first connector 5, second connector 6, elastic deformation connector 7, mounting seat 11 and enhanced contact mechanism 12 inside the device can be packaged to form a relay structure. At the same time, the power supply 1 can be a DC68V power supply 1 connected to the locomotive, and the voltage is reduced to DC12V by the step-down coil 2. Therefore, the HXN5 locomotive parking brake pressure controller detection device forms a device consisting of four parts: a shell, an indicator light, a relay, and a transformer.
[0051] The device can also have a structure of two-way detection of the pressure controller 10. For example, another rotating rod 3 is set at the other end of the coil 2, and another group of indicator lights and selection switches are also set, so that two groups of pressure controllers 10 can be connected at the same time. For the two groups of pressure controllers 10, the order of action and release can be judged by the order of lighting.
[0052] The above are only some embodiments of the present application, and the protection scope of the present application is not limited to the above embodiments. For ordinary technicians in this technical field, some improvements and modifications without departing from the creative design of the present application should also fall within the protection scope of the present application.
