Description

Technical Field

[0001] The utility model relates to the technical field of rail transportation, in particular to an auxiliary maintenance device for a motor vehicle headlight, which is especially used when a repair workshop inspection warehouse is used to replace the headlight. Background Art

[0002] Headlights are currently being repaired and replaced in a repair and inspection warehouse. For the Fuxing model, since the front of the car is relatively long and the headlights are also relatively long, about 2.1 meters, the headlights are located on the curved side of the front of the car, forming a triangular gap between the side of the car and the second-floor platform. When replacing, most of the headlights are in the part with a larger gap. It is difficult for personnel to use strength sideways when replacing, and there is a safety risk of falling.

[0003] Currently, headlight replacements utilize the Curry's second-floor platform, requiring two people to work together. Replacing a headlight typically takes a day (approximately 6-8 hours). Due to the extended maintenance time, the vehicle is usually impounded for replacement during the day. Vehicles have four headlights, and sometimes, to maintain road operation, one or two headlights are broken, and the vehicle is left to function. The main reason for not replacing them regularly is the inconvenience of replacement.

[0004] The second method is to use a scissor lift truck for maintenance on the non-platform side. However, when the scissor lift truck is raised to the maintenance height, there is also a gap between the platform and the side of the truck. This makes maintenance possible, but it is not convenient. Currently, the truck with the headlight to be repaired is moved to the side with the platform for maintenance.

[0005] The shortcomings of the current maintenance are:

[0006] (1) It is inconvenient for personnel to approach the maintenance area;

[0007] (2) It is inconvenient for two people to work together to change the headlight sideways;

[0008] (3) There is a safety risk of people falling due to large gaps. Utility Model Content
