Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some but not all of the elements related to the present invention are shown in the drawings.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection or a removable connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

In order to improve the maintenance efficiency of the bogie of locomotive, reduce the occupation of locomotive to the space simultaneously, as shown in fig. 1, the utility model provides a locomotive bogie remove-out device, including maintenance track 1, pit tunnel 3 and bogie remove-out mechanism 5, maintenance track 1 includes canned paragraph 11 and can dismantle section 12, dig in the below that can dismantle section 12 and be equipped with the pit 2 of disassembling that is used for disassembling bogie 7, be provided with car lifting jack 6 and bogie remove-out mechanism 5 in disassembling the pit 2, pit tunnel 3 with disassemble pit 2 intercommunication, bogie remove-out mechanism 5 can shift out through pit tunnel 3 with the bogie 7 of disassembling from the locomotive.

The bogie 7 detached from the locomotive is moved out through the bogie moving-out mechanism 5 through the pit tunnel 3, the process that the bogie 7 is moved out through lifting the locomotive to a certain height in the prior art is changed into underground operation, the height of the locomotive body lifted by the locomotive lifting jack 6 is reduced, the overhaul operation of the bogie 7 of the locomotive can be completed in a small space, and the overhaul and dismounting efficiency of the bogie 7 is improved.

In order to move the bogie 7 out of the pit tunnel 3 conveniently, further, the device further comprises a moving-out pit 4, the moving-out pit 4 and the dismantling pit 2 are arranged at intervals along the extending direction of the maintenance track 1, one end of the pit tunnel 3 is communicated with the dismantling pit 2, and the other end of the pit tunnel is communicated with the moving-out pit 4. The bogie moving-out mechanism 5 bears the bogie 7, passes through the pit tunnel 3 and then is transferred to the ground from the moving-out pit 4 for maintenance and repair, and the operation of a maintainer is facilitated.

Further, in order to facilitate the removal of the bogie 7 and the smooth lifting from the removal pit 4 to the ground, optionally, the bogie removal mechanism 5 comprises a flat car 51 and a bogie lifting assembly 52, the bogie lifting assembly 52 being disposed on the flat car 51, and the bogie lifting assembly 52 being used for carrying and lifting the bogie 7. Through the flat car 51 be convenient for bogie 7 to transport in pit tunnel 3, through using bogie lift subassembly 52, when bogie 7 transports in pit tunnel 3, reduce the height of bogie 7 to reach through pit tunnel 3 smoothly and shift out pit 4, reach and shift out pit 4 after, lift bogie 7, the height that bogie 7 of being convenient for rose to the ground.
