Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile repair, in particular to the technical field of safe operation method of lifting vehicle by color bar adjustment. BACKGROUND

[0002] The safety of automobile repair is the top priority. Two-column lifting machine is one of the devices used most frequently by automobile repair personnel and also the device with the most safety risks. Safety accidents caused by lifting machines occur frequently. How to effectively protect the life and property safety of practitioners is the top priority for relevant departments and managers. Excluding problems such as product quality and maintenance, accidents caused by lifting machines are mostly caused by improper operation, and improper operation is largely due to the lifting preparation process, such as not reasonably parking the vehicle in the lifting station, left leaning of the vehicle head, right leaning of the vehicle body, and too forward center of gravity of the vehicle body, etc. Figure 1 Various inaccurate parking position conditions of vehicle. For the position of the vehicle parked in the station, it is impossible to judge whether the parking position is reasonable and accurate by visual observation, which further leads to the safety hidden danger of the lifted vehicle falling and the safety production risk of operating under the vehicle, etc. Figure 3 Illustration of correct parking of vehicle in station.

[0003] Improving repair efficiency and productivity. In the production process, due to the different driving skills and requirements of operators, the vehicle is often improperly parked in the station and needs to be adjusted multiple times. Even after the vehicle is lifted to a certain height, the vehicle needs to be lowered and adjusted again due to improper parking, which greatly reduces the production efficiency and poses a serious safety hazard.

[0004] The existing lifting station basically does not have positioning marks in the parallel direction of the vehicle. The vehicle is prone to be inclined and parked in the station, such as left leaning of the vehicle head, right leaning of the vehicle head, left leaning of the vehicle body, right leaning of the vehicle body, etc. At this time, the lifting machine lower support arm can barely support the vehicle. However, due to the inclined position of the vehicle, the extension length of the lifting machine lower support arm is inconsistent, the center of gravity of the lifted vehicle is not on the center line of the lifting machine, and the weight distribution is uneven, which poses a serious safety hazard.

[0005] Even if the vehicle is parked parallel to the station, the left and right distances between the vehicle and the lifting machine are equal, but the center of gravity of the vehicle should be on the transverse center line of the lifting machine. The center of gravity of the lifted vehicle is too forward or too backward, the weight distribution is uneven, and there is a serious safety hazard. Referring to the accompanying drawings of the specification Figure 2 Illustration of improper front and rear center of gravity distribution of vehicle on lifting machine. The center of gravity of the lifted vehicle is not on the center line of the lifting machine. Due to the uneven weight distribution of the vehicle, operation under the vehicle is prone to cause excessive shaking of the lifting machine, and even the possibility of vehicle sliding. SUMMARY
