Description
Technical Field
[0001] The utility model relates to the technical field of railway vehicles, in particular to a vehicle coupler anti-dropping device. Background Art
[0002] In rail transportation, the number of carriages is often increased to increase the transport volume. Multiple carriages are usually connected by couplers, such as James couplers. In order to prevent uncoupling due to uneven road conditions, the couplers are usually treated to prevent uncoupling.
[0003] Most of the existing anti-slip treatments are to set connecting plates on both sides of the coupler. When the couplers of adjacent carriages are connected, the connecting plates are clamped at the same time to improve the connection strength of the adjacent carriages. When the couplers are detached, they can temporarily take on the role of the couplers. It can be seen that even with this anti-slip treatment method, the coupler will still detach, and the problem of coupler detachment cannot be solved. Moreover, when the coupler is detached, the couplers are only connected by the connecting plates, and the connection strength is reduced. The couplers are easy to separate, which may cause safety accidents such as derailment in serious cases, posing a huge threat to the lives and property safety of the staff. Utility Model Content

In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0032] This embodiment provides a coupler anti - detachment device, as Figure 1 and Figure 2 shown, which is used to connect the couplers (not shown in the figure) of two adjacent carriages, can effectively prevent the couplers from detaching, avoid derailment of the carriages, and ensure the life and property safety of the staff.
[0033] The coupler anti - detachment device includes an insertion member 1, a first connecting member 2 and a second connecting member 3. Among them, two insertion members 1 are provided. The two insertion members 1 are configured to be vertically inserted into the insertion holes of two adjacent couplers, and at least part of the insertion member 1 extends out of the insertion hole. The first connecting member 2 is detachably connected to the upper ends of the two insertion members 1, and the first connecting member 2 can be in tight contact with the upper surface of the coupler. At least one second connecting member 3 is provided. The second connecting member 3 is detachably connected to the lower ends of the two insertion members 1, and can be in tight contact with the lower surface of the coupler. When performing the coupler anti - detachment treatment, the two insertion members 1 are respectively inserted into the insertion holes of two adjacent couplers, and the first connecting member 2 and the second connecting member 3 are respectively connected to the upper and lower ends of the insertion member 1, thereby further enhancing the connection strength between two adjacent couplers.
[0034] When there is a height difference in the road surface, the two hooks will move relative to each other in the vertical direction, thereby driving the two plug-in components 1 to move vertically, so that the first connector 2 is pressed against the upper surface of the hook or the second connector 3 is pressed against the lower surface of the hook, thereby limiting the hooks in the vertical direction to prevent the two hooks from continuing to move relative to each other, avoiding the derailment of the carriage caused by the hooks being separated from each other, and ensuring the safety of life and property of the staff. Even if the amplitude of the relative vertical movement of the two hooks is too large, under the action of the hook anti-detachment device, the hooks will be reset to the original state again to ensure the stability of the carriage. In addition, when it is necessary to release the carriage connection, only the first connector 2 or the second connector 3 needs to be disassembled, and the plug-in component 1 can be taken out of the socket, which is convenient for further disassembly of the hooks. The structure is simple and easy to operate.
[0035] Alternatively, if Figure 1 and Figure 2 As shown, the first connecting member 2 includes a first ring body 21, two mounting seats 22 and two second ring bodies 23. The two second ring bodies 23 are respectively arranged on the two mounting seats 22, and the first ring body 21 and the two second ring bodies 23 are both connected by penetration. The mounting seat 22 is threadedly connected to the upper end of the plug-in 1, and the cross-sectional area of the mounting seat 22 is larger than the cross-sectional area of the jack. By setting the first ring body 21 and the second ring body 23 to be connected by penetration, the two mounting seats 22 can be connected. When there is a height difference in the road surface, the hooks of the two adjacent carriages will move relative to each other vertically, thereby driving the plug-in 1 to move until the mounting seat 22 abuts against the surface of the hook. At this time, the mounting seat 22 will limit the plug-in 1 vertically to prevent it from moving further, so that the hook is limited, avoiding the relative movement of the hooks of the two adjacent carriages from being too large and disengaging from each other, thereby ensuring the safety of life and property of the staff.
[0036] In this embodiment, the first ring body 21 includes an O-ring, and the second ring body 23 includes a U-ring, and both ends of the U-ring are connected to the mounting seat 22. In other embodiments, the first ring body 21 can be set to a rectangular ring or the like, and the second ring body 23 can be set to an O-ring or a rectangular ring or the like as needed, which is not limited here.
[0037] Optionally, the anti-drop device for the coupler also includes a limiter. A through hole 11 is provided at the lower end of the plug-in component 1, a through hole 2 is provided at the second connector 3, and the limiter passes through through hole 11 and through hole 2. When the second connector 3 is connected to the coupler 1, the through hole 11 can be aligned with the through hole 2, and then the limiter is passed through the through hole 11 and through hole 2, so as to further strengthen the connection strength between the second connector 3 and the coupler 1 and prevent the second connector 3 from falling off. When the two couplers move relative to each other vertically, the second connector 3 will press against the lower surface of the coupler. At this time, the limiter can disperse the impact force of the coupler on the second connector 3, reduce the burden of the connection of the second connector 3, and thus extend its service life.
[0038] Exemplarily, the limiting member includes a hairpin pin. In other embodiments, a screw or a bolt pin, etc. can also be selected as the limiting member according to needs, which is not limited herein.
[0039] Optionally, as Figure 1 and Figure 2 shown, the insertion member 1 includes an insertion rod portion 12 and a connecting portion 13. The first connecting member 2 is disposed at the upper end of the insertion rod portion 12, and the length of the insertion rod portion 12 is adjustable. The connecting portion 13 is disposed at the lower end of the insertion rod portion 12 and is detachably connected to the second connecting member 3. By setting the insertion rod portion 12 to be length-adjustable, the required insertion depth can be flexibly selected according to the axial length of the coupler socket, ensuring that the insertion member 1 can penetrate the socket and at least partially protrude, thereby facilitating the connection of the insertion member 1 with the first connecting member 2 and the second connecting member 3, strengthening the connection strength between two adjacent couplers, and preventing the couplers from separating from each other.
[0040] Optionally, the insertion rod portion 12 includes a first rod body and a second rod body. The first connecting member 2 is connected to the upper end of the first rod body, and the inside of the lower end of the first rod body is hollow. One end of the second rod body extends into the first rod body and is threadedly connected to the inner wall of the first rod body. The end of the second rod body away from the first rod body is connected to the connecting portion 13. When the axial length of the coupler socket is short, at this time, the insertion member 1 only needs to be inserted into a shorter part to achieve connection and fixation. The second rod body can be screwed into the first rod body to reduce the overall length of the insertion member 1. When the axial length of the coupler socket is long, a part of the second rod body can be screwed out of the first rod body to increase the overall length of the insertion member 1, increase the insertion depth of the insertion member 1, ensure that the insertion member 1 can protrude from the socket, and thus realize the connection between the insertion member 1 and the first connecting member 2 and the second connecting member 3, strengthening the connection strength of the coupler.
[0041] In this embodiment, as Figure 1 and Figure 2 shown, two second connecting members 3 are provided. The two second connecting members 3 are respectively threadedly connected to the two insertion members 1. The structural form is simple, facilitating the disassembly and installation of the insertion member 1, and the cross-sectional area of the connecting member is larger than the cross-sectional area of the socket, which can prevent the insertion member 1 from separating from the coupler.
[0042] Exemplarily, the second connecting member 3 includes a slotted nut. The slotted nut can provide a better locking effect during tightening, and at the same time, it will undergo a certain degree of elastic deformation, thereby increasing the friction force between the slotted nut and the insertion member 1, and thus improving the tightness and reliability of the connection. In other embodiments, a hexagonal nut, etc. can also be selected as the second connecting member 3 according to actual needs, which is not limited herein.
[0043] In some embodiments, a second connector 3 is provided. The second connector 3 includes a first plug-in portion and a second plug-in portion connected to each other, and the first plug-in portion and the second plug-in portion are detachably connected to the two plug-in components 1 respectively.
[0044] Optionally, both the first plug-in portion and the second plug-in portion are provided with threaded holes, the radial direction of the threaded holes is perpendicular to the insert 1, and the insert 1 is screwed into the threaded holes, which has a simple structure and is easy to disassemble and install.
[0045] In other embodiments, both the first plug-in portion and the second plug-in portion are provided with connecting holes. The radial direction of the connecting hole is perpendicular to the insert 1, and the insert 1 is inserted into the connecting hole. One of the inner wall of the connecting hole and the outer wall of the insert 1 is axially provided with a plurality of anti-retraction barbs, and the other is axially provided with a plurality of slots, and the anti-retraction barbs have a state of being inserted into and out of the slots. When connecting the insert 1 and the second connector 3, the insert 1 is vertically inserted into the connecting hole, and the insert 1 can only move in one direction in the connecting hole until the second connector 3 is completely connected to the insert 1. At this time, the anti-retraction barb is inserted into the slot, and the second connector 3 vertically limits the insert 1 to prevent it from being separated from the coupler, thereby strengthening the connection between the two adjacent couplers and preventing the couplers from being separated from each other.
[0046] Specifically, a plurality of rows of barbs are arranged at intervals along the circumferential direction on the inner wall of the connection hole, and a plurality of barbs are arranged at intervals along the axial direction of the connection hole in each row. Similarly, a plurality of slots are arranged at intervals along the circumferential direction on the outer wall of the insert 1, and a plurality of slots are arranged at intervals along the axial direction of the connection hole in each row, which can improve the connection strength of the insert 1 in the connection hole.
[0047] It should be noted that the second connector 3 and the plug-in component 1 are both made of plastic, and have a certain strength and elastic deformation capacity, so that the anti-retraction barb can be easily inserted into and removed from the slot. When the anti-detachment device needs to be removed, the plug-in component can be directly cut off to release its connection with the coupler.
[0048] In other embodiments, a plurality of retaining barbs may be axially arranged on the outer wall of the insert 1, and a plurality of retaining grooves may be axially arranged on the inner wall of the connecting hole.
[0049] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
