Description

Technical Field

[0001] The utility model relates to a locomotive reconnection device, in particular to an auxiliary connection device for connecting and locking locomotive reconnection sockets, belonging to the technical field of locomotive reconnection devices. Background Art

[0002] When a locomotive is reconnected, it needs to be connected together through a reconnection socket and a reconnection line; when a locomotive is reconnected, in order to ensure that there will be no connection problems, it is necessary to ensure that the reconnection plug and the reconnection socket can be tightly connected, but the current locomotive reconnection is directly plugged and unplugged by hand, without reliable protection measures, and the reconnection socket cover is only closed with a spring, which requires the cover to be kept open all the time. Therefore, the existing reconnection plug will become tightly matched and difficult to plug and unplug during actual operation, and a labor-saving plug-in and plug-out structure is required to ensure that the reconnection plug is installed in place; and because the number of existing locomotives in operation is extremely large, the improvements made must be made on the same structure of the original reconnection plug and reconnection socket, otherwise there will be problems of high cost of change and difficulty in construction, so it is very necessary to improve this; and the difficulty of the improvement lies in the fact that the two stop points that need to be locked for the connection between the reconnection socket and the reconnection socket cover are not in the same direction, and the plug-in and pull-out function must be realized.

[0003] After searching, no relevant patent technology literature has been found. The closest patent documents are as follows:

[0004] 1. The utility model patent with application number CN201420604496.9 and name “A reconnection socket installation structure for rail vehicles” discloses a reconnection socket installation structure for rail vehicles, including a round tube, a first flange installed at one end of the round tube, and a second flange installed at the other end of the round tube. The socket pad of the reconnection socket is connected to the first flange through a fastening structure, and the second flange is connected to the vehicle body; a first waterproof gasket is provided between the socket pad and the first flange. However, the reconnection socket structure proposed in the patent is more troublesome than the existing reconnection socket connection, and only improves the waterproof problem of the reconnection, and does not improve the connection method of the reconnection socket or the plug itself.

[0005] 2. The invention patent with application number CN201711001104.4 and name “A locomotive reconnecting socket mounting seat” discloses a reconnecting socket protective cover. The protective cover shell is compatible with the reconnecting socket, and a protective cover mounting hole is provided on the shell. The protective cover mounting hole corresponds to the mounting bolt position of the reconnecting socket. When the protective cover is put on the reconnecting socket, the mounting bolts of the reconnecting socket pass through the protective cover mounting hole to fix the protective cover to the locomotive end plate. A wiring hole for the outlet of the cable is also provided on the shell, and an anti-slip pad is installed between the protective cover and the locomotive end plate. Although the patent involves the improvement of the reconnecting socket protective cover, the proposed improvement method proposes to reinforce it by adding bolts. This not only adds trouble to the connection, but also easily leads to poor sealing of the protective cover, so the above-mentioned problems still exist.

[0006] 3. The invention patent with application number CN202010793726.0 and name “Reconnection socket protective cover” discloses an anti-loosening device for a reconnection connector, which includes a plug and a socket. The anti-loosening device includes: a first connector, which includes a first fixing portion and a first clamping portion provided on the first fixing portion, and the first fixing portion is used to connect with the plug; a second connector, which includes a second fixing portion and a second clamping portion provided on the second fixing portion, and the second fixing portion is used to connect with the socket, and the second clamping portion is used to buckle with the first clamping portion. However, the structure of this anti-loosening device is too complicated, and the operation is very inconvenient, and it does not solve the problems mentioned above.

[0007] From the description of the above patent, it can be seen that although some people have proposed a technical solution to improve the anti-loosening of the reconnection connector, which also includes improvements on the reconnection protective cover, the proposed technical solution is not practical and does not solve the technical problems mentioned above. Therefore, the problems mentioned above still exist and need to be further studied. Utility Model Content
