Detailed Description
The "longitudinal direction" in the present invention means a direction in which the steel rail extends; "front" means the direction of train travel; the maximum limit projection position of the kicking leg and the minimum limit projection position of the kicking leg respectively mean the vertical projection of the kicking leg when the kicking leg rotates around the push iron pin shaft in the horizontal plane relative to the maximum angle position of the longitudinal rotation and the vertical projection of the kicking leg when the kicking leg rotates to the minimum angle position relative to the longitudinal rotation, namely the longitudinal projection of the kicking leg when the car coupler is respectively in the locking state and the full opening state.
FIG. 8 is a perspective view of a knuckle push iron in an embodiment of a railway car coupler of the present invention; referring to fig. 8, the present embodiment provides a knuckle push iron, including: and an iron pushing pin shaft 73 which is vertically arranged and used for being hinged with the hook body, wherein a kicking leg 71 used for driving the hook tongue to horizontally rotate and a lock seat 72 used for being matched with the lock iron are respectively and fixedly arranged on the iron pushing pin shaft 73, and the lower surface of the kicking leg 71 is away from the lower surface of the lock seat 72 by a first distance.
The knuckle push iron of the embodiment can be used in a railway vehicle coupler. Fig. 6 is a schematic diagram of the transmission principle of the traction force between the knuckle and the coupler body in the coupler of the railway vehicle. Referring to fig. 6 and 8 together, a railway car coupler generally comprises: the hook comprises a hollow hook body 1 which is longitudinally arranged, wherein one end of the hook body 1 is provided with an opening, a coupler knuckle 2 is arranged at the opening, the front end of the coupler knuckle 2 is a head part, the rear end of the coupler knuckle 2 is a tail part 201, the head part of the coupler knuckle 2 is hinged with the hook body 1 through a coupler knuckle pin shaft 21 which is vertically arranged, and the tail part 201 of the coupler knuckle 2 extends into the hook body 1; the coupler knuckle push iron and the lock iron can be transversely arranged in the coupler body 1 and behind the tail part of the coupler knuckle 2, so that the coupler knuckle push iron is driven by the lock iron to rotate around the push iron pin shaft 73, the kicking leg 71 of the coupler knuckle push iron kicks the tail part 201 of the coupler knuckle and drives the coupler knuckle 2 to rotate around the coupler knuckle pin shaft 21, and a lower traction table 104 used for being in contact with the front end face of the tail part 201 of the coupler knuckle to transfer traction force is formed on the inner bottom surface of the coupler body 1; the kick leg 71 and the lock seat 72 on the iron pushing pin shaft 73 can be perpendicular to the iron pushing pin shaft 73, or can form an acute angle with the kick leg 71, and the value of the first distance can be determined according to the vertical heights of the kick leg 71, the lock seat 72 and the lower traction table 104, as long as the vertical distance between the lower surface of the kick leg 71 and the inner bottom surface of the hook body 1 is ensured to be larger than the vertical height of the lower traction table 104, so as to ensure that the lower traction table 104 does not interfere with the horizontal rotation of the kick leg 71, that is, the rotation area of the kick leg 71 is above the top surface of the lower traction table 104, so that the extension length of the lower traction table 104 is not limited by the kick leg 71 of the hook tongue iron; thus, the strength of the hook body 1 can be improved by increasing the extension length of the lower traction table 102 in the horizontal direction; in particular, the lower traction table 104 can be extended in the horizontal direction beyond the minimum limit projection position of the kicking leg 71, and optimally, the lower traction table 104 can be extended all the way to the side wall of the hook body to improve the hook body strength as much as possible.
The coupler knuckle push iron provided by the embodiment can also realize the locking and unlocking functions of the coupler, the following specific description process can simultaneously refer to fig. 2 and 8, when the coupler is in a locking state (when a train runs), the lock iron 5 locks the position of a lock seat 72 of the coupler knuckle push iron, at the moment, the kicking leg 71 does not act on the coupler knuckle 2, and the head of the lock iron is at the lowest position; when the car coupler needs to be opened (after the train stops, the hooking between the car couplers needs to be released), the lock iron 5 can be controlled by the lock pin mechanism to trigger the lock seat 72, so that the coupler knuckle push iron rotates anticlockwise in a horizontal plane, along with the rotation of the kicking leg 71, the end face of the tail end of the kicking leg 71 can contact the push surface on the coupler knuckle 2, and the coupler knuckle 2 rotates clockwise under the kicking of the kicking leg 71, namely the coupler knuckle 2 is gradually opened; when the kicking leg 71 is rotated to the maximum limit angle position, the knuckle is also brought to the full open state. It should be noted that the position of the knuckle 2 kicked by the kicking leg 71 of the knuckle push iron is the pushing surface of the knuckle, which may be one side surface of the knuckle 2 or a certain position on the side surface of the knuckle 2, and of course, since the position of the kicking leg 71 of the knuckle push iron in the embodiment in the vertical direction is higher than the position of the kicking leg of the knuckle push iron in the prior art, the position of the pushing surface in the embodiment on the knuckle is higher than the position of the pushing surface 211 (shown in fig. 5) on the knuckle in the prior art.
The coupler knuckle push iron provided by the embodiment can enable the coupler knuckle body adopting the coupler knuckle push iron to be inside by improving the relative positions of the kicking legs and the lock base, the horizontal rotating area of the kicking legs and the space occupied by the horizontal extending area of the lower traction table do not have intersection any more, and then the strength of the coupler body can be improved by increasing the extending length of the lower traction table of the coupler body, so that the possibility of cracks and even breakage of the lower traction table of the coupler body after a train runs for a period of time is greatly reduced, and the running safety of railway vehicles is improved.
In the above embodiment, for most railway car couplers, the top surface of the lower traction table 104 is 25mm higher than the lower surface of the lock base 72, and correspondingly, the first distance between the kick leg 71 on the coupler knuckle push iron and the lock base can be greater than or equal to 25mm, so that the layout in the cavity inside the coupler body can be effectively optimized, and the strength of the coupler body can be further improved.
Furthermore, the top end of the push iron pin shaft 73 is fixedly provided with a positioning piece 731 with a diameter larger than that of the push iron pin shaft 73, namely, the edge of the positioning piece 731 extends out of the periphery of the push iron pin shaft 73, and the push iron pin shaft 73 vertically penetrates through the hook body 1, so that the positioning piece 731 at the top of the push iron pin shaft can realize vertical positioning of the push iron. The coupler of the embodiment does not need to adopt other positioning pieces to position the coupler knuckle push iron, so that the structure is further simplified, and the cost is saved.
Furthermore, in order to further match the structure of the coupler knuckle push iron in the embodiment, the coupler knuckle structure of the coupler can be improved; fig. 9 is a perspective view of the improved coupler knuckle, as shown in fig. 9, an elongated connecting portion 203 is arranged between a head portion 204 and a tail portion 201 of the coupler knuckle 2, a groove 205 may be formed on a side surface of the connecting portion 203 along a longitudinal direction, and a bottom surface of the groove 205 is a pushing surface 211 for contacting with an end surface of the kick leg 71. The arrangement of the pushing surface 211 in this embodiment can make the end of the kicking leg 71 slide along the groove 205 when kicking the knuckle, so as to prevent the kicking leg 71 from being displaced in the vertical direction due to vertical impact or vibration, so as to further ensure that the knuckle 2 rotates in the horizontal plane, thereby reducing unnecessary wear while ensuring the opening angle.
Fig. 10 is a schematic structural view of another embodiment of the knuckle push iron of the present invention, and in another embodiment of the present invention, as shown in fig. 7 and 10, the push iron pin 73 includes a center pin (not shown) inserted into the hook body 1 and a cylindrical shaft sleeve 702 coaxially sleeved on the center pin, and the kicking leg 71 and the lock base 72 are respectively and fixedly disposed on the outer side of the shaft sleeve 702; in the solution of this embodiment, two ends of the center pin can respectively extend out of the shaft sleeve 702 and can be fixedly connected with the horizontally arranged hook 1, that is, the center pin is vertically and fixedly disposed on the hook 1, so that the shaft sleeve 702 can rotate around the center pin 701, thereby similarly realizing the hinge joint between the coupler knuckle push iron and the hook 1.
Certainly, the center pin and the hook body 1 are not necessarily fixedly connected with each other, which can not move relatively at all, but only need to vertically position the center pin, for example, the top end of the center pin can be provided with a positioning part for vertically positioning the center pin, for example, the positioning plate can be arranged on the top of the center pin and has a diameter larger than the center hole of the hook body 1 for penetrating the center pin, and the positioning plate can prevent the center pin from slipping; furthermore, a positioning plate similar to the top can be arranged at the bottom end of the center pin at the same time, so that the axial movement of the center pin is further prevented. The connecting form of the center pin and the hook body of the embodiment ensures that the kicking legs and the lock seat horizontally rotate around the center pin, further simplifies the processing and assembling procedures, and is beneficial to reducing the manufacturing and maintaining cost.
