Description

[Detailed description of the invention] The present invention relates to automobile maintenance equipment, and in particular utilizes a lift that runs through multiple work bays to efficiently carry out tasks such as cleaning, parts replacement or repair, installation adjustment, and painting during maintenance. This invention relates to an automobile maintenance device that can be used to perform maintenance work well.

Traditionally, multiple work bays (spaces) were used,
Cars that have been lifted up by the lift device are moved to any location in these work bays, cleaned,
The present inventor proposed a device as shown in FIG. 1 as an automobile maintenance device for performing repairs.

That is, the rail member 1 buried in the floor etc.
and running wheels 2 running on the inner wall of this rail member 1.
A one-post lift 6 comprising a base part 3 having a base part 3 and a support part 5 provided perpendicularly from the base part 3 and having a driving wheel 4 mounted thereon that runs on the outer wall of the rail member 1; A lift-up member 8 that moves up and down the support column 5 by a lifting device 7 provided therein, a hanger member 10 that suspends and holds a car provided on a support piece 9 of this lift-up member, and a The provided anti-shake roller 11 and the anti-shake roller 1
1 and a ceiling guide rail 12 for guiding the guide rail 1.

However, the automobile maintenance device configured in this manner does not oscillate because the one-post lift 6 travels while being guided by the rail member 1 and the ceiling guide rail 12, and therefore the automobile sways. However, in cases where it is difficult to install the ceiling guide rail 12 on the ceiling, or in automobile repair shops where the ceiling height is relatively low, it cannot be used or the range of use is significantly limited. It had the disadvantage of being Furthermore, since at least two columns 13 must be installed on the floor to support the ceiling guide rail 12, the effective area of the work bay is reduced, and at the same time, the overall size of the maintenance equipment is increased. I had no choice but to do it. Therefore, installation work was time-consuming and construction costs were high.

In view of the above-mentioned drawbacks of the conventional technology, the present invention allows the lift to run without swinging without using the ceiling guide rail 12 or anti-shaking rollers 11, and at the same time reduces the total height of the lift or makes it extremely small. This makes it possible to use it even in automobile repair shops with relatively low ceiling heights, and installation work is easy and construction costs are low.Furthermore, the small number of work bays can be used effectively to improve work efficiency. There are many things you can do to improve your car, such as visiting a repair shop.
