Description

Technical Field

[0001] The utility model relates to the technical field of locomotive walkways, in particular to a fixed walkway for locomotive body assembly. Background Art

[0002] At present, the final assembly of the existing locomotive car body carbon steel structure needs to be constructed using a fixed walkway. Generally, the walkway surface is about 2 meters above the ground and about 25 meters long. The fixed walkways are symmetrically distributed on the left and right sides of the locomotive product. Due to the wide variety of locomotive product models, the width is generally 2.8 meters to 3.4 meters and the length is 16 meters to 22 meters. Therefore, a telescopic pedal needs to be embedded on the locomotive product side in the width direction of the fixed walkway. The telescopic pedal needs to be retracted according to the width of the vehicle to facilitate construction personnel to assemble, weld, inspect, accept, and repair locomotive products on-site operations; some locomotive products need to be operated under the vehicle during final assembly, so the fixed walkway needs to be designed with 4 gaps to arrange 4 driving machines to lift the locomotive products, so that construction personnel can enter the vehicle to perform construction operations.

[0003] Therefore, in view of the above problems, a fixed walkway for locomotive body assembly is proposed. Utility Model Content

[0004] The camshafts are connected to the two guide rails of the vehicle body by two guide rails, each of which is connected to the two guide rails by a toothed wheel.

[0005] The extending pedal one has the same structure as the extending pedal two, and the extending pedal one includes a pedal body, and connecting slide rails are respectively arranged on both sides of the pedal body, and the connecting slide rails are slidably arranged on the guide rail sliders. The extending pedal one is provided with a socket for plugging in the plug-in fence, and the extending pedal one is provided with a slot one, and the slot one is respectively plugged with a cover plate five and a cover plate six.

[0006] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0007] The utility model provides telescopic pedal one, telescopic pedal two and telescopic pedal three, and cover plates five and six are respectively inserted into slots one of telescopic pedal one and telescopic pedal two. When the driving machine changes position, the unused gaps can be used to install the cover plates, and the pedals can be retracted, thereby ensuring the safety of construction and the adaptability to different types of vehicles. The mobile driving machine can change its position without moving the locomotive product, thereby ensuring the continuity and high efficiency of production. BRIEF DESCRIPTION OF THE DRAWINGS
