Description

Technical Field

[0001] The utility model relates to the technical field of rail transit vehicles, in particular to an automatic detection device for detecting the horizontal centering position of a hook. Background Art

[0002] The coupler is used to connect the locomotive and the vehicle or the vehicle and the vehicle, transmit traction and impact force, and keep a certain distance between the vehicles. It is one of the most basic and important vehicle components. The coupler is connected to the vehicle body through a pivotable joint, which allows the coupler to produce angular displacement relative to the vehicle body, so that the train can bend to adapt to various tracks, and connect the air path, circuit and machinery inside the train, so that the vehicle forms a whole.

[0003] Normal coupling of the coupler is a prerequisite for ensuring the vehicle's reconnected operation. During the coupling process, due to the tilt of the vehicle body during driving or the change in the vertical curvature caused by the different running lines, it is necessary to ensure that the coupler is in the center position, that is, the coupler and the hook head of the tractor or the towed vehicle are on the same horizontal line to ensure the safe and reliable connection of the coupler. When the coupler is in the center position, the coupler can be automatically coupled; when the coupler is in a non-center position, it is necessary to manually operate the auxiliary coupling device to couple the coupler. In the prior art, it is often necessary to manually get off the vehicle to observe whether the coupler is in the center position, and then determine whether the coupler can be automatically coupled, which not only wastes human resources, but also reduces coupling efficiency. Summary of the invention

[0004] In view of the deficiencies existing in the related art, the utility model provides an automatic detection device for detecting the horizontal centering position of a coupler.

Thus, a feature defined as "first", "second", and "third" may explicitly or implicitly include one or more of the features.

[0036] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] As attached Figure 1 -Attached Figure 6 As shown, in an exemplary embodiment of the utility model, an automatic detection device for detecting the horizontal centering position of a coupler includes:

[0038] The first bearing member is fixedly connected to the vehicle body; the first bearing member is arranged on the vehicle body and moves with the vehicle body, and the vehicle body is a tractor or a towed vehicle;

[0039] The second bearing member is rotatably connected to the first bearing member, and the coupler 2 is mounted on the second bearing member; the coupler 2 is fixedly connected to the second bearing member, and an angular displacement is generated between the second bearing member and the first bearing member;

[0040] Centering detection assembly: comprising a detection member and a sensor unit, wherein one of the detection member and the sensor unit is installed on the first bearing member, and the other is installed on the second bearing member;

[0041] The installation position of the centering detection component is configured such that when the axial center line of the coupler 2 and the axial center line of the vehicle body are located in the same vertical plane, the sensing unit can detect the position information of the detection member and generate a signal.

[0042] In this embodiment, when the coupler is in the center position, the relative position relationship between the first load-bearing component and the second load-bearing component is also fixed. By detecting this relative position relationship through the center detection component, it can be determined whether the coupler is in the center position. The sensor unit is provided with a certain detection range. When the axial center line of the coupler 2 and the axial center line of the vehicle body are located in the same vertical plane, the detection member falls into the detection range of the sensor unit and outputs a signal, and it is determined that the vehicle can be coupled, so as to improve the vehicle coupling efficiency.

[0043] In some embodiments, the detection member is mounted on the first bearing member and located on the axial center line of the vehicle body, and the sensor unit is mounted on the second bearing member and located on the axial center line of the coupler. The detection member is mounted on the first bearing member, and the sensor unit rotates with the coupler, generating an angular displacement with the vehicle body. When the coupler moves to the centering position, the detection member appears within the detection range of the sensor unit and generates a signal to confirm that the coupling can be performed.

[0044] In some embodiments, the detection member is a detection plate 4, and the sensing unit is a proximity sensor 5. The proximity sensor 5 is a sensor that replaces contact detection methods such as limit switches and is used for detection without contacting the detection object. It can detect the movement information and existence information of the object and convert it into an electrical signal. In this embodiment, the proximity sensor 5 can detect the existence information of the detection plate 4 and convert it into an electrical signal to determine whether the coupler is in the center position. Exemplarily, the proximity sensor 5 is set to a normally open state. When there is no detection object within the sensing distance of the proximity sensor, the proximity sensor 5 has no signal output; when the detection object enters (or relatively enters) into the sensing range of the proximity sensor 5, the proximity sensor 5 outputs a signal.

[0045] In some embodiments, the first bearing component is a cam plate 1; the second bearing component is a coupler mounting plate 3;

[0046] The cam plate 1 is arranged parallel to the upper side of the coupler mounting plate 3, and the detection plate 4 is arranged on the lower surface of the cam plate 1; the cam plate 1 is arranged in the coupler buffer device to realize the mechanical centering of the coupler. When the coupler has an angular displacement, the centering mechanism composed of the cam plate 1, the roller and the disc spring provides a restoring force to return the coupler to the centering position;

[0047] The sensing end 501 of the proximity sensor 5 is arranged on the upper surface of the coupler mounting plate 3, and when the detection plate 4 is located directly above the proximity sensor 5, the proximity sensor 5 outputs a signal. The mounting positions of the detection plate 4 and the proximity sensor 5 are configured such that when the coupler is in the center position, the detection plate 4 is located directly above the proximity sensor 5.

[0048] In this embodiment, during the return process of the coupler, the coupler mounting plate 3 drives the coupler 2 to produce an angular displacement, and the sensing end 501 of the proximity sensing sensor 5 arranged on the upper surface of the coupler mounting plate 3 also rotates accordingly. When the detection plate 4 appears within its detection range, it is determined that the coupler is in the center position at this time, and the coupling can be performed. When the coupler pitches a certain angle in the vertical plane, the proximity sensing sensor 5 pitches synchronously with the coupler, and the relative position (height direction) of the proximity sensing sensor 5 and the detection plate 4 changes to a certain extent, but the detection plate 4 is still within the sensing range of the proximity sensing sensor 5, so it does not affect the detection of the relative position change of the detection plate 4 along the horizontal direction by the proximity sensing sensor 5, so as to improve the adaptability of the device.

[0049] In some embodiments, a threaded hole is formed on the coupler mounting plate 3, and a thread corresponding to the threaded hole is provided on the proximity sensing sensor 5, and the proximity sensing sensor 5 is detachably connected to the coupler mounting plate 3 through the thread. In this embodiment, the depth of the proximity sensing sensor 5 embedded in the coupler mounting plate 3 can be adjusted through the cooperation between the thread and the threaded hole, so as to adjust the detection distance of the sensing end 501 to a suitable range, so as to improve the accuracy of detecting the position of the detection plate 4.

[0050] In some embodiments, it further comprises: a waterproof connector 6, which is installed at the electrical connection end of the proximity sensor 5. The waterproof connector has the characteristics of being waterproof, sealing, and corrosion-resistant, which not only improves the sealing of the electrical communication end of the proximity sensor, but also prevents water, gas and other impurities from penetrating, thereby improving the service life and reliability of the device.

[0051] In some embodiments, the threaded hole passes through the coupler mounting plate 3 , and the waterproof connector 6 is located below the coupler mounting plate 3 .

[0052] In some embodiments, the detection plate 4 is folded to form three panels, namely the first panel 401, the second panel 402 and the third panel 403, the first panel 401 is connected to the lower surface of the cam plate 1, the second panel 402 extends toward the direction of the coupler mounting plate 3, the third panel 403 is arranged parallel to the coupler mounting plate 3, the sensing end 501 of the proximity sensing sensor detects the position of the third panel 403, when the third panel 403 is directly above the proximity sensing sensor 5, the proximity sensing sensor 5 outputs a signal. In this embodiment, the first panel 401 and the lower surface of the cam plate 1 are installed by bolts, the second panel 402 is used to adjust the relative height between the first panel 401 and the third panel 403, so that the third panel 403 can fall into the detection range of the proximity sensing sensor 5, when the proximity sensing sensor 5 rotates synchronously with the coupler mounting plate 3, the third panel 403 is relatively out of the sensing range of the proximity sensing sensor 5.

[0053] As attached Figure 3 and attached Figure 5 As shown, in some embodiments, the width of the third plate surface 403 is consistent with the width of the sensing range of the proximity sensing sensor 5, and when the third plate surface 403 is completely directly above the proximity sensing sensor 5, the proximity sensing sensor 5 outputs a signal. In this embodiment, in order to further improve the detection accuracy of the sensing unit, the width of the third plate surface 403 is adapted to the sensing width of the proximity sensing sensor 5, so as to avoid that when the proximity sensing sensor 5 rotates with the coupler mounting plate 3 to detect only part of the third plate surface 403 within its sensing range, that is, outputs a signal, there is a certain deviation, resulting in the coupler not being in a completely centered position.

[0054] As attached Figure 4 and attached Figure 6 As shown, in some embodiments, a through hole 404 is provided on the third plate surface 403, and the plate surface width on both sides of the through hole 404 can fall into the sensing range of the proximity sensing sensor 5, and the diameter of the through hole 404 is consistent with the width of the sensing range of the proximity sensing sensor 5. In this embodiment, the detection object of the proximity sensing sensor 5 is changed from the third plate surface 403 to the position of the through hole 404, that is, when the coupler is in the center position, the through hole 404 is within the sensing range of the proximity sensing sensor 5, and when the coupler rotates in the horizontal plane, the plate surface on both sides of the through hole 404 falls into the sensing range of the proximity sensing sensor 5.

[0055] 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.

[0056] 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.
