Referring to fig. 1 to 7, the present embodiment provides a coupler 100, and the coupler 100 includes a coupler body 1, a knuckle 2 and a pin 3. The hook body 1 comprises a hook head 12, a hook body 13 and a hook tail 11, wherein the hook head 12, the hook body 13 and the hook tail 11 are an integrally formed integral piece, namely the hook body 1.

The top end surface of the first connecting portion 1221 is connected to the bottom end surface of the hook body 121, and this connection involves a small number of connecting surfaces, so that the hook body 1 with the anti-slip cover can be manufactured by combining the anti-slip cover mold with the existing hook body mold. The first anti-slip portion 1222 is coupled to a bottom end of the first coupling portion 1221 such that the first anti-slip portion 1222 does not interfere with a knuckle of the opposite coupler when the coupler is coupled to the opposite coupler.
In concrete implementation, the coupler of the embodiment is mainly an improvement on 13-series couplers, so that the coupler is suitable for all 13-series couplers, namely, the anti-drop platform of the embodiment has the advantages of simple structure, good process formability, standardized and generalized structure, and can be widely applied to all 13-series couplers in China. Of course, the anti-floating platform structure of this embodiment may also be applied to the improvement of other series of couplers according to actual needs, and is not limited specifically here.
The coupler 100 of the embodiment comprises a coupler body 1, a coupler knuckle 2 and a pin shaft 3, wherein the coupler body 1 comprises a coupler head 12, a coupler body 13 and a coupler tail 11, the coupler knuckle 2 is rotatably connected to the coupler head 12 through the pin shaft 3, before the coupler is coupled with an opposite coupler, the coupler knuckle 2 is rotated outwards around the pin shaft 3 to open the coupler, and after the coupler is coupled with the opposite coupler, the coupler knuckle 2 is rotated inwards around the pin shaft 3 to lock the coupler, so that coupling between a locomotive and a vehicle or between the vehicle and the vehicle is realized. Through setting up gib head 12 and including gib head body 121 and with gib head body 121 integrated into one piece's anticreep platform, when the coupling links with offside coupling, the vertical moving range of offside coupling knuckle can be restricted to the anticreep platform to two couplings that prevent to link and pull out each other and lead to train separation accident.
Meanwhile, the anti-separation platform includes the lower anti-separation platform 122, the lower anti-separation platform 122 includes a first connecting portion 1221 and a first anti-separation portion 1222, the first connecting portion 1221 extends along the axial direction of the pin shaft 3, and the first anti-separation portion 1222 extends along the radial direction of the pin shaft 3. By arranging that the top end surface of the first connecting part 1221 is connected with the bottom end surface of the coupler head body 121 and the bottom end of the first connecting part 1221 is connected with the first anti-falling part 1222, on one hand, the connection mode between the lower anti-falling platform 122 and the coupler head body 121 is simplified, thereby being beneficial to simplifying the structure of the coupler with the anti-falling platform; on the other hand, the anti-drop platform die can be customized only, and the anti-drop platform die is spliced with the existing coupler body die without the anti-drop platform to manufacture the coupler with the anti-drop platform, so that repeated customization of the coupler body die is avoided, and the production cost of the coupler with the anti-drop platform is reduced; moreover, the anti-disengaging platform die is of a standardized and generalized structure and can be repeatedly used, and the coupler with the anti-disengaging platform does not need to be customized every time the coupler is produced. For example, the anticreep platform die can be mated with all 13 series existing hook dies without anticreep platforms to produce hooks with anticreep platforms.
Optionally, one end of the coupler 100, which is provided with the knuckle 2, is used for being coupled with the opposite-side coupler 400, and the first anti-falling part 1221 is arranged below the opposite-side coupler 400 in a blocking manner; and the surface of one side of the anti-falling platform, which is far away from the opposite side coupler, is a flat surface. That is, the anti-drop platform of the present embodiment is different from the structure in which the reinforcing rib extending to the coupler body is disposed on the back surface of the anti-drop platform in the related art, and the surface of the anti-drop platform on the side away from the coupler on the opposite side is kept flat without any reinforcing rib, so that the structure of the anti-drop platform is simplified, and the process formability of the coupler body 1 is better; and the structure of the anti-drop platform die is simplified, the production cost of the die is reduced, and the production cost of the car coupler is further reduced.
Optionally, there is a smooth transition between the edge of the anti-roll off stage and the surface of the anti-roll off stage that faces away from the opposite coupler. That is, the anti-drop platform of the present embodiment is different from the structure in which the reinforcing wrapping is provided at the edge of the anti-drop platform in the related art, the edge of the anti-drop platform of the present embodiment smoothly transitions with the surface of the anti-drop platform on the side away from the opposite coupler, and no reinforcing wrapping is provided, so that not only is the structure of the anti-drop platform simplified, but also the process formability of the coupler body 1 is better; and the structure of the anti-drop platform die is simplified, the production cost of the die is reduced, and the production cost of the car coupler is further reduced.
Referring to fig. 7, the bottom of the opposite-side coupler 400 is provided with an auxiliary interlocking bracket 41 extending toward the first retaining portion 1221, and after the coupler 100 is coupled to the opposite-side coupler 400, a gap (L in fig. 7 represents the gap) between an edge of the first retaining portion 1222 and an edge of the auxiliary interlocking bracket 41 of the opposite-side coupler 400 is in a range of 15mm to 16 mm. For example, the gap between the edge of the first anti-slip part 1222 and the edge of the auxiliary interlocking bracket 41 of the opposite coupler 400 may be set to be 15mm, 15.3mm, 15.5mm, 15.7mm, 16mm or any other value within the range of 15mm to 16mm according to actual needs. Therefore, the gap between the edge of the first anti-slip part 1222 and the edge of the auxiliary interlocking bracket 41 of the opposite coupler 400 is prevented from being too small, which causes the structural interference between the lower anti-slip platform 122 and the opposite coupler 400 when the coupler 100 is coupled, thereby being beneficial to ensuring the smooth coupling between the coupler 100 and the opposite coupler 400.
Optionally, the anti-separation platform and the hook head body 121 form an integral piece through an integral casting mode, and simulation analysis verifies that the anti-separation platform of the embodiment can bear loads of at least 890kN along the axial direction of the pin shaft 3, so that the strength requirement of the anti-separation platform is met.
Optionally, the anti-disengaging platform can also include an anti-disengaging platform (not shown in the figure), the upper anti-disengaging platform includes a second connecting portion and a second anti-disengaging portion, the second connecting portion extends along the axial direction of the pin shaft, the second anti-disengaging portion extends along the radial direction of the pin shaft, the bottom end face of the second connecting portion is connected with the top end face of the hook head body, and the top end of the second connecting portion is connected with the second anti-disengaging portion. It can be understood that the upper anti-drop platform and the lower anti-drop platform have substantially the same function and are arranged in substantially the same manner, and specific reference may be made to the description of features and effects of the lower anti-drop platform, which is not described herein again.
Further, the coupler of this embodiment further includes a coupler yoke and a coupler yoke pin (not shown in the figure), the coupler yoke is provided with a coupler yoke pin hole, the coupler yoke pin is arranged in the coupler yoke pin hole in a penetrating manner so as to connect the coupler yoke with the coupler yoke, and the coupler yoke is used for being connected with a vehicle. The coupler yoke key and the pin shaft are parallel to each other, namely, the pin shaft extends along the vertical direction, and the coupler yoke key also extends along the vertical direction.
Further, the present embodiment further includes a buffer (not shown in the drawings), which is disposed at the hook tail and is used for buffering the impact and vibration along the extending direction of the hook body. In the concrete implementation, longitudinal impact and vibration can be caused by the fact that vehicles collide with each other when a train runs due to the change of locomotive traction force or during starting, braking and shunting operation of the train, and the buffer has the function of dissipating the impact and vibration between the vehicles, so that the damage effect on a train body structure and loaded goods is reduced. The working principle of the shock absorber is to relax the impact force by compressing the elastic member while absorbing the impact energy by friction and damping during the deformation of the elastic member.
In summary, the coupler 100 of the present embodiment is configured such that the top end surface of the first connecting portion 1221 is connected to the bottom end surface of the coupler head body 121, and the bottom end of the first connecting portion 1221 is connected to the first anti-falling portion 1222, so that on one hand, the connection manner between the anti-falling platform and the coupler head body 121 is simplified, and thus the structure of the coupler with the anti-falling platform is simplified; on the other hand, the anti-drop platform die can be customized only, and the anti-drop platform die is spliced with the existing coupler body die without the anti-drop platform to manufacture the coupler with the anti-drop platform, so that repeated customization of the coupler body die is avoided, and the production cost of the coupler with the anti-drop platform is reduced; moreover, the anti-disengaging platform die is of a standardized and generalized structure and can be repeatedly used, and the coupler with the anti-disengaging platform does not need to be customized every time the coupler is produced. For example, the anticreep platform die can be mated with all 13 series existing hook dies without anticreep platforms to produce hooks with anticreep platforms.
