Description

Technical Field

[0001] The utility model belongs to the technical field of rail vehicles, and in particular relates to a coupler state detection device. Background Art

[0002] With the rapid development of railway transportation, improving train marshaling efficiency and safety has become an urgent problem to be solved in the railway system. In my country, the mainline locomotive couplers generally use the traditional James coupler. Although this type of coupler has a long history, its degree of automation is low. In actual use, the coupler status during the coupling or uncoupling process often requires manual observation and confirmation, which is not only inefficient, but also poses a safety hazard. Especially in bad weather or poor visibility, the accuracy and timeliness of manual inspection are difficult to guarantee.

[0003] The working principle of the James coupler includes three basic states: locked position, unlocked position and fully open position. The relative positions and interactions between the coupler tongue and the coupler lock are significantly different in these three states, which makes it possible to automatically detect the state of the James coupler through sensors.

[0004] There are some designs in the prior art for devices that detect the status of couplers through sensors. However, due to the differences in the specific structures and working principles of couplers, the existing detection devices are usually not applicable to James-type couplers. In addition, the installation of existing detection devices usually requires an additional sensor fixing bracket, which not only increases the complexity and cost of coupler status detection, but may also interfere with the normal operation of the coupler. Summary of the invention

[0005] The purpose of the utility model is to solve one of the above-mentioned technical problems and to provide a coupler state detection device which can detect the three states of the locked position, unlocked position and fully open position of the James type coupler in real time and accurately, so as to provide reliable basic data for the automatic coupling and uncoupling control of the James type coupler.

[0042] In the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0043] The technical solution of the utility model is described in detail below in conjunction with specific embodiments and the accompanying drawings.

[0044] As attached Figure 1-8 As shown, in an illustrative embodiment of a coupler status detection device of the utility model, the detection device is suitable for a locomotive coupler including a coupler tongue and a coupler lock, and the detection device includes a coupler, a coupler lock sensor 5, a coupler tongue sensor 4 and a controller (not shown in the figure).

[0045] Among them, as attached Figure 1-4 As shown, the coupler comprises a hook body 1 , a hook tongue 2 and a hook lock 3 .

[0046] The hook body 1 is made of high-strength metal material and is used to provide support for the hook lock 3 and the hook tongue 2 .

[0047] The hook tongue 2 is rotatably mounted on the front end of the hook body 1 through a hook tongue pin. After installation, the hook tongue 2 can rotate around the hook tongue 2 pin in the hook head, and is used to cooperate with the hook tongue 2 of another coupler to achieve the connection of two vehicle couplers.

[0048] The hook lock 3 is movably installed in the hook body 1, and is used to lock the position of the hook tongue 2 to ensure the stability and reliability of the hook connection. The hook lock 3 can move up and down in the hook body 1. When the hook lock 3 falls, it is in a locked state. In this state, the position of the hook tongue 2 can be fixed to prevent the hook tongue 2 from accidentally turning away or falling off. When the hook lock 3 is lifted, it is in an unlocked state. In this state, the lock on the position of the hook tongue 2 can be released, so that the hook tongue 2 can be turned outward, thereby realizing the hook removal operation.

[0049] According to the relative positions of the hook tongue 2 and the hook lock 3, the coupler has three states: locked position, unlocked position and fully open position. In the locked position, the coupler is in a connected state, and the hook tongue 2 and the hook lock 3 are closely matched to ensure the stability of the train operation; in the unlocked position, the coupler is in a state of being connected or about to be separated, and there is a certain gap between the hook tongue 2 and the hook lock 3; and in the fully open position, the coupler is completely separated, allowing the train to dismantle or regroup.

[0050] The hook tongue sensor 4 is fixedly mounted on the hook body 1 and is used to detect the rotation state of the hook tongue 2 .

[0051] The hook lock sensor 5 is fixedly mounted on the hook body 1 and is used to detect the position of the hook lock 3 .

[0052] The controller is electrically connected to the coupler tongue sensor 4 and the coupler lock sensor 5 , and is configured to determine the state of the coupler based on the rotation state of the coupler tongue 2 and the position of the coupler lock 3 .

[0053] The controller can be electrically connected to the hook tongue sensor 4 and the hook lock sensor 5 in a parallel connection mode or in a series connection mode. When the parallel logic mode is adopted, the state of the coupler can be identified by judging whether the two sensors are in the triggered state respectively, and then judging the logic of the controller. The series connection mode has a faster feedback response speed. When either of the two sensors is in the untriggered state, the state of the coupler can be judged.

[0054] The utility model can be applicable to 105-type couplers, as well as James-type couplers with the same principle as 13-type, 15-type, 16-type and 17-type couplers.

[0055] The utility model can accurately detect the position of the hook lock 3 and the rotation state of the hook tongue 2 by installing a hook lock sensor 5 and a hook tongue sensor 4 on the hook body 1, and then judge the coupler state through the controller, thereby realizing real-time and accurate detection of the three states of the locomotive coupler, namely the locked position, the unlocked position and the fully open position, and providing reliable basic data for the automatic coupling and uncoupling operation control of the coupler.

[0056] In some embodiments of the utility model, in order to detect the rotation state of the hook tongue 2, the hook tongue sensor 4 is installed on the top of the hook body 1, and after installation, the sensing end of the hook tongue sensor 4 is located above the hook tongue 2, so as to detect the rotation state of the hook tongue 2. When the hook tongue 2 is closed, the hook tongue 2 is outside the detection area of ​​the hook tongue sensor 4, and the hook tongue sensor 4 is not triggered. When the hook tongue 2 is fully opened, the hook tongue 2 is located within the detection area of ​​the hook tongue sensor 4, and the hook tongue sensor 4 is triggered to generate an electrical signal.

[0057] Furthermore, in order to facilitate the detection of the rotation state of the hook tongue 2, a hook tongue sensor induction member 42 cooperating with the hook tongue sensor 4 is also included, which is fixedly installed on the top of the hook tongue 2 and can move closer to and away from the hook tongue sensor 4 as the hook tongue 2 rotates.

[0058] When the hook tongue 2 is closed, the hook tongue sensor sensing component 42 is away from the hook tongue sensor 4 and is located outside the detection area of ​​the hook tongue sensor 4, and the hook tongue sensor 4 is not triggered; when the hook tongue 2 is fully opened, the hook tongue sensor sensing component 42 is close to the hook tongue sensor 4 and is located within the detection area of ​​the hook tongue sensor 4, and the hook tongue sensor 4 is triggered to generate an electrical signal.

[0059] In some embodiments of the present invention, in order to install the hook tongue sensor 4 on the hook body 1, a connecting piece 41 is provided on the top of the hook body 1, and the connecting piece 41 has a through hole, and the hook tongue sensor 4 is fixedly installed in the through hole by a nut. This installation method makes the installation of the hook tongue sensor 4 easier, avoids the interference of the additional fixing bracket on the operation of the vehicle coupler, and also facilitates the maintenance and replacement of the hook tongue sensor 4.

[0060] In some embodiments of the present invention, the hook tongue sensor 4 uses a proximity switch to achieve contactless detection of the rotation state of the hook tongue 2, avoid mechanical wear, and extend the service life of the hook tongue sensor 4. One end of the hook tongue proximity switch is a sensing end, and the other end is provided with a thread and a nut is sleeved. When installing, the hook tongue proximity switch is inserted into the through hole of the top connecting piece 41 of the hook body 1, adjusted to a suitable position, and the nut is screwed along the thread toward one side of the connecting piece 41, thereby fixing the hook tongue proximity switch. It should be noted that the hook tongue sensor 4 can also use other detection switches with the same function.

[0061] In some embodiments of the present invention, in order to detect the position of the hook lock 3, the hook lock sensor 5 is fixedly installed on the side wall of the hook body 1 above the hook lock 3. After installation, the sensing end of the hook lock sensor 5 is located above the hook lock 3 to detect the position of the hook lock 3.

[0062] When the hook lock 3 moves down and is in a locked state, the hook lock 3 is outside the detection area of ​​the hook lock sensor 5, and the hook lock sensor 5 is not triggered. When the hook lock 3 moves up to a predetermined height, the hook lock 3 enters the detection area of ​​the hook lock sensor 5, and the hook lock sensor 4 is triggered to generate an electrical signal.

[0063] In some embodiments of the utility model, in order to install the hook lock sensor 5 on the hook body 1, a mounting hole for the hook lock sensor 5 is opened on the side wall of the hook body 1. The mounting hole passes through the side wall of the hook body 1, and the hook lock sensor 5 is inserted into the mounting hole and fixed in the mounting hole by a nut.

[0064] In some embodiments of the present invention, the hook lock sensor 5 uses a proximity switch to detect the position of the hook lock 3 without contact, thus avoiding mechanical wear and extending the service life of the hook lock sensor 5. One end of the hook lock proximity switch is a sensing end, which is located inside the hook body 1 after installation, and the other end is provided with a thread and a nut is sleeved. When installing, the hook lock proximity switch is inserted into the installation hole of the side wall of the hook body 1, adjusted to a suitable position, and the nut is screwed toward the side wall of the hook body 1 along the thread, thereby fixing the hook lock proximity switch. It should be noted that the hook lock sensor 5 can also use other detection switches with the same function.

[0065] It should also be noted that the hook tongue proximity switch and the hook lock proximity switch used in the present invention are of different lengths.

[0066] In some embodiments of the utility model, the coupler further includes a lower locking pin 6, an unhooking pendulum block 7 and an unhooking crank 8; wherein, one end of the lower locking pin 6 is connected to the hook lock 3 through a slide groove to control the hook lock 3 to move up and down in the hook body 1, and rotate slightly according to the change of the center of gravity; the other end extends to the outside of the hook head and is plugged into the unhooking pendulum block 7; the unhooking crank 8 is angled with the hook body 1 and fixedly connected to the unhooking pendulum block 7, so that when the unhooking crank 8 is operated, the lower locking pin 6 is driven to move and then the hook lock 3 is controlled to move in the hook body 1.

[0067] In some embodiments of the utility model, the coupler further includes a hook tongue push iron 9, which is installed inside the hook body 1 and located above the hook lock 3, with one end in contact with the hook tongue 2, and the other end in contact with the hook lock 3 when the hook lock 3 moves upward to a predetermined position. When the coupler is unlocked, the hook lock 3 moves upward, pushing one end of the hook tongue push iron 9, and the other end of the hook tongue push iron 9 pushes the hook tongue 2, so that the hook tongue 2 rotates to unlock.

[0068] The specific detection logic of the coupler state of the utility model is:

[0069] Lock position: as attached Figure 5 As shown, in the locked position, the hook tongue 2 is closed and the hook lock 3 is locked.

[0070] In the locked position, the hook lock 3 is located on the inner wall of the hook body 1, with one side being blocked by the inner wall of the hook body 1 and the other side blocking the tail of the hook tongue 2, so that the hook tongue 2 cannot rotate in the hook body 1.

[0071] At this time, since the hook lock 3 moves down and locks, the hook lock sensor 5 is not triggered; the hook tongue 2 is in a closed state, and the hook tongue sensor 4 is not triggered; the sensor detects that both the hook lock sensor 5 and the hook tongue sensor 4 are in a no-signal state, and determines that the coupler is in the locked position.

[0072] The locked position is the connection position of the coupler, and force can be transmitted between the couplers.

[0073] Unlock position: As attached Figure 6 As shown, the hook tongue 2 is closed and the hook lock 3 is lifted up to unlock.

[0074] In the unlocking position, the unhooking crank 8 is pulled down, and the lower locking pin 6 is lifted by the unhooking swing block 7, thereby lifting the hook lock 3, and the notch at the bottom of the hook lock 3 is seated on the corresponding blocking edge of the inner wall of the hook body 1. The state of the hook tongue 2 is consistent with the locking position, which is the closed state, but the hook tongue 2 is not locked at this time and can be rotated.

[0075] At this time, since the hook lock 3 moves up and enters the detection area of ​​the hook lock sensor 5, the hook lock sensor 5 is triggered and generates an electrical signal; the hook tongue 2 is still in the closed state, and the hook tongue sensor 4 is not triggered. The sensor detects that the hook lock sensor 5 is in the signal state and the hook tongue sensor 4 is in the no signal state, and determines that the coupler is in the unlocked position.

[0076] The unlocking position is the unhooking position of the coupler, at which time the couplers of the two vehicles can be separated.

[0077] Fully open position: as attached Figure 7-8 As shown, the hook tongue 2 is fully opened, and the hook lock 3 continues to be lifted and then dropped.

[0078] When the unhooking crank 8 is further pulled down, the lower locking pin 6 drives the hook lock 3 to continue to lift up, and the hook lock 3 pushes the hook tongue push iron 9, and the hook tongue push iron 9 pushes the hook tongue 2 to fully open it. After the unhooking crank 8 is released, the hook lock 3 drops and sits on the hook tongue 2 due to gravity.

[0079] At this time, the hook lock 3 is further lifted and then falls, but is still within the detection range of the hook lock sensor 5, the hook lock sensor 5 is triggered, and an electrical signal is generated; the hook tongue 2 is in the open state, the hook tongue sensor 4 is triggered, and an electrical signal is generated. The sensor detects that both the hook lock sensor 5 and the hook tongue sensor 4 are in a no-signal state, and determines that the coupler is in the fully open position.

[0080] The fully open position is the unhooking position of the coupler. Before coupling, the coupler needs to be moved to the fully open position.

[0081] Among them, the judgment logic of the controller is shown in Table 1.

[0083] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0084] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for which protection is requested in the utility model.
