Description

Technical Field

[0001] The utility model relates to the technical field of electric couplers, in particular to an electric coupler pushing mechanism and a train. Background Art

[0002] With the continuous advancement of rail transit technology, the design and performance improvement of the electric coupler pusher, as a key component for connecting and disconnecting the electrical connection between trains, is particularly important. With the increase in the number of vehicle end parts and components, the installation space of the electric coupler pusher is limited, which requires the pusher to be more compact to avoid interference with the coupler buffer system and other components.

[0003] As a new type of high-speed train, the maglev train uses electromagnetic force to achieve non-contact suspension and guidance between the train and the track, and then uses the electromagnetic force generated by the linear motor to pull the train to run. Its non-contact suspension and guidance system enables the train to achieve a higher running speed, but at the same time, because the bottom of the train is close to the track surface, the space under the car is very narrow. After the coupler is assembled on the train, it is limited by the length of the coupler, requiring the electric coupler push device to achieve the push and self-locking functions within a limited space.

[0004] However, the electric coupler pushing mechanism in the prior art, such as the cylinder direct-pushing structure and the reverse-pushing self-locking pushing mechanism, all require cylinder action, which makes the pushing mechanism larger in size and cannot meet the compact space requirements of the maglev train.

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

[0045] 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.

[0046] As attached Figure 1 -Attached Figure 6 As shown, in an illustrative embodiment of an electric coupler pushing mechanism of the utility model, it includes:

[0047] A push bracket 1, on which a first support arm 101 and a second support arm 102 are arranged at intervals; the first support arm 101 and the second support arm 102 are symmetrically arranged and extend out of the push bracket 1 in the same direction;

[0048] A rotating shaft 2, the rotating shaft 2 is rotatably mounted between the first support arm 101 and the second support arm 102; both ends of the rotating shaft 2 are rotatably connected to the support arms on the same side, so as to realize self-rotation in the support arms;

[0049] A rotating arm 301, one end of which is connected to the rotating shaft 2; the rotating arm 301 can move into the relative space between the first support arm 101 and the second support arm 102; the rotating arm 301 is fixedly connected to the rotating shaft 2 to rotate with the rotating shaft 2, and the length of the rotating arm 301 is less than the length of the support arm. For example, the rotating arm 301 can be folded in the pushing bracket;

[0050] A support rod 4, one end of the support rod 4 is connected to the electric coupler 5, and the other end of the support rod 4 is rotatably connected to the rotating arm 301;

[0051] The rotating shaft 2 can rotate in the first support arm 101 and the second support arm 102 , so that the rotating arm 301 rotates with the rotating shaft 2 , so that the support rod 4 drives the electric coupler 5 to slide horizontally.

[0052] In the above embodiment, the pushing mechanism has a simple structure, a compact design, and occupies a small space. When driving the electric coupler 5 to slide horizontally, the rotating arm 301 can be folded in the internal space formed by the pushing bracket to improve the space utilization efficiency of the location of the electric coupler 5 and meet the compactness requirements of the maglev train for the electric coupler pushing device.

[0053] In order to provide a simple and effective self-locking mechanism, in some embodiments, a locking structure is provided between the first support arm and the rotating shaft for limiting the relative rotation between the two. When they are rotated into place, the positions of the two can be locked to limit the relative rotation between the two.

[0054] As a specific implementation of the self-locking structure, a connecting block 1011 is provided on the outer side of the first support arm 101, a first hole 10111 is provided on the connecting block 1011, the first end of the rotating shaft 2 is rotatably connected to the connecting block 1011, a second hole is provided on the first end of the rotating shaft 2, and the positions of the first hole 10111 and the second hole are configured such that when the rotating shaft 2 rotates to the point where the electric coupler 5 is in the first state, the first hole 10111 and the second hole overlap;

[0055] The connecting block 1011 is provided with a first fastener 1012 , which is inserted into the first hole 10111 and can be inserted into the second hole when the first hole 10111 and the second hole overlap.

[0056] In this embodiment, the second hole is formed on the rotating shaft 2, and rotates with the rotating shaft 2. The rotating shaft 2 rotates to drive the electric coupler 5 to move horizontally. When the electric coupler 5 moves to the first state, the second hole rotates to a fixed position, and this position coincides with the position where the first hole 10111 is opened, so that the first fastener 1012 can be inserted into the second hole. After the first fastener 1012 is inserted into the second hole, the movement state of the rotating shaft 2 is locked, and it cannot continue to rotate to drive the electric coupler to move, so as to realize the self-locking function of the electric coupler in the first state, thereby improving the stability and safety of the electric coupler.

[0057] Specifically, during operation, the first fastener 1012 is configured as an indexing pin, and the operator lifts or lowers the indexing pin through the lifting rod to control the locking and unlocking of the electric coupler in the first state.

[0058] In some embodiments, the first state is the electric coupler ready-to-hook state, that is, the electric coupler is retracted.

[0059] In some embodiments, the push mechanism further comprises:

[0060] The limit block 103 is arranged on the pushing bracket 1 along the extending direction of the first support arm 101 and the second support arm 102 . When the rotating shaft 2 rotates until the electric coupler 5 is in the second state, the rotating arm 301 abuts against the limit block 103 .

[0061] In this embodiment, the limit block 103 is formed in the internal space of the pushing bracket 1, and the abutment position is set according to the movement of the rotating arm 301. Specifically, the rotation of the rotating shaft 2 drives the electric coupler 5 to move horizontally. When the electric coupler 5 moves to the second state, the rotating arm 301 rotates to the relative space between the first support arm 101 and the second support arm 102. At this time, the position of the rotating arm 301 is the abutment position of the limit block 103 and it. Exemplarily, the position of the limit block 103 can be formed above the rotating arm 301 at this time and abut it to limit the rotation tendency of the rotating arm 301, so that it cannot continue to drive the electric coupler 5 to move horizontally, so as to realize the self-locking function of the electric coupler 5 in the second state, further improve the stability and safety of the electric coupler 5, and at the same time provide additional support and positioning for the electric coupler, ensuring the accuracy and repeatability of the pushing process.

[0062] In some embodiments, the second state is the electric coupler connected state, that is, the electric coupler extended state.

[0063] In some embodiments, two rotating arms 301 are symmetrically arranged, and two supporting rods 4 are symmetrically arranged, and each supporting rod 4 is respectively connected to the electric coupler 5 and the corresponding rotating arm 301. The two rotating arms 301 are respectively connected to the rotating shaft 2. For example, an elastic pin is arranged in the middle of the rotating shaft 2, and both ends of the elastic pin are respectively connected to one rotating arm 301. At the same time, the symmetrically arranged rotating arms 301 and supporting rods 4 provide the electric coupler 5 with more uniform force, enhance the balance and stability of the overall structure, and simplify the design, which is convenient for large-scale production and maintenance.

[0064] In some embodiments, the rotating arm 301 includes:

[0065] The second fastener 303 is disposed between the two rotating arms 301, and its two ends are respectively rotatably connected to the adjacent rotating arms 301; the first ends of the two support rods 4 are respectively connected to the second fastener 303; illustratively, the second fastener 303 is configured as a pin, which can rotate relative to the rotating arms 301 at both ends, and the first ends of the two support rods 4 are respectively fixed to the pin by nuts;

[0066] When the rotating shaft 2 rotates to the electric coupler 5 in the second state, the second fastener 303 abuts against the limit block 103. In this embodiment, the second fastener 303 abuts against the limit block 103 to provide a more compact and stable connection method.

[0067] In some embodiments, the support rod 4 is configured as a retractable telescopic rod. This design allows the push mechanism to adjust its length according to actual needs, thereby improving the adaptability and flexibility of the mechanism.

[0068] In some embodiments, the outside of the telescopic rod is sleeved with a spring 401, and the two ends of the spring 401 are respectively connected to the electric coupler 5 and the second end of the rotating arm 301. This provides the pushing mechanism with the ability to buffer and absorb energy, reduces impact and wear, and prolongs the service life of the mechanism. At the same time, under the action of the spring force, there will be a greater contact force between the two electric couplers, ensuring that the electric couplers are connected reliably.

[0069] In some embodiments, an operating block 201 is provided at the first end of the rotating shaft 2, and the operating block 201 is in the shape of a hexagonal square head or a disc. The operator manually operates the operating end of the rotating shaft 2 through a long wrench to control the rotation of the rotating shaft 2. The hexagonal square head or the disc shape provides a convenient operating interface, so that the operator can more easily control the rotation of the rotating shaft 2, thereby improving the convenience and safety of the operation.

[0070] In some embodiments, the electric coupler 5 is arranged below the mechanical coupler 6, and the second end of the pushing bracket 1 is connected to the mechanical coupler 6. This layout makes the installation and maintenance of the electric coupler more convenient, while ensuring the synchronous operation of the electric coupler and the mechanical coupler, thereby improving the overall work efficiency.

[0071] In some embodiments, the pushing mechanism can be arranged at the front end or the rear end of the electric coupler 5 along the connecting direction of the electric coupler 5 according to the space position under the vehicle.

[0072] In addition, the utility model also provides a train, including an electric coupler 5, and the electric coupler 5 includes an electric coupler pushing mechanism. The electric coupler pushing mechanism of the present invention can be widely used in trains, especially for modern high-speed trains that require compact space layout, such as maglev trains, etc. Its compact design and self-locking function make the electrical connection of the train more stable and reliable, while reducing maintenance costs.

[0073] 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.

[0074] 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.
