  In recent years, in consideration of safety and the environment, the floor of the vehicle has been lowered to prevent entanglement and noise, and the lower part of the vehicle has become difficult to see. When such a vehicle is lifted up by the conventional vehicle maintenance lift device, it is difficult to set the lift receiving portion of the lift at the lifting point of the vehicle because the lower portion of the vehicle is difficult to see. Even if the set work is performed by illuminating the lower part of the vehicle using a handy light, etc., it is necessary to work around the handy light, etc., and the work efficiency is poor, and the lifting point of the vehicle comes off the lift However, there is a problem that the vehicle is dropped or the vehicle is damaged.

  The present invention solves such a problem, and even in a vehicle in which the lower part of the vehicle is difficult to see, the lifting point of the vehicle can be easily set in the lift receiving portion of the lift, thereby improving the working efficiency, and the vehicle falling and It is an object of the present invention to provide a vehicle maintenance lift device that prevents a vehicle from being damaged.

  According to the present invention, in order to achieve the above object, an illuminating means for illuminating the lower surface of the vehicle is provided near a lift for supporting the lower surface of the vehicle and lifting up the vehicle.

  ADVANTAGE OF THE INVENTION According to this invention, even if it is a vehicle in which the lower part of a vehicle is difficult to see, the lifting point of a vehicle can be easily set to the lift receiving part of a lift, work efficiency is improved, and a fall of a vehicle and damage to a vehicle are caused. Provided is a vehicle maintenance lift device that prevents the vehicle.

It is a top view of the important section of Example 1 of the present invention. FIG. 2 is a sectional view taken along line II-II of FIG. 1. It is a sectional view of the whole lift device. FIG. 4 is a block diagram of a control system of the lighting unit.

  An embodiment of the present invention will be described below.

  First Embodiment A vehicle maintenance lift device according to a first embodiment of the present invention will be described with reference to the drawings.

  1 is a plan view of a main part of a first embodiment of the present invention, FIG. 2 is a sectional view taken along line II-II of FIG. 1, FIG. 3 is a cross-sectional view of the entire lift device, and FIG. It is a block diagram.

  1 is a pit formed on the floor of a vehicle maintenance shop, 2 is a fixed lift fixed to the front end of the pit 1, and 3 is a movable lift capable of moving in the pit 1 in the longitudinal direction. The lift 3 is formed so as to be able to travel on its own by a traveling drive device (not shown) by engaging wheels with rails for a movable lift laterally provided in a groove shape along both sides of the upper opening of the pit 1. ing.

  Reference numerals 4A and 4B denote fixed cover members connected before and after the fixed lift 2, and reference numerals 5A and 5B denote moving cover members connected before and after the movable lift 3.

  Reference numeral 6 denotes a pit cover. The pit cover 6 is formed by connecting lids in a strip shape, and is provided laterally in the pit 1 along both side edges of the upper opening in the pit 1. The ends of the pit cover 6 are connected to the movable cover bodies 5A and 5B by engaging the lower surfaces of both sides of the lid unit with the rail for cover, and the pit cover rail is moved with the movement of the movable lift 3. To move while sliding. The other end of the pit cover 6 is suspended at the end of the pit 1 for storage.

  Reference numeral 7 denotes an illuminating unit. The illuminating unit 7 includes an illuminating lamp 7B made of, for example, an LED mounted on a bottom surface of a concave portion 7A formed on an upper surface of each of the fixed cover members 4A and 4B and the moving cover members 5A and 5B. A translucent plate 7C such as a PVC plate, which is located above the illuminating lamp 7B and is interlocked between steps formed on upper edges of both sides of the concave portion 7A, and both ends just above the translucent plate 7C. And a protective plate 7D which is engaged with the step and has a large number of light-transmitting portions such as gratings. The protection plate 7D is provided to protect the illuminating lamp 7B even if a heavy object rides on the protection plate 7D. Further, a metal plate 7E for protecting the translucent plate 7C is interposed between the translucent plate 7C and the protective plate 7D at the peripheral portion.

  4, reference numeral 8 denotes control means, 9 denotes illuminance adjustment means, 10 denotes irradiation direction adjustment means, 11 denotes vehicle detection means, and the control means 8 includes the illuminance adjustment means 9, the irradiation direction adjustment means 10, and the A signal from the detection means 11 is input to output a control signal to each of the illumination lamps 7B.

  Next, the operation and effect of the vehicle maintenance lift device of the first embodiment will be described.

  When the vehicle, that is, the car A, enters the place of the lift of the maintenance shop as shown in FIG. 3, the detecting means 11 detects that the car is at the place of the lift, and the detecting means 11 The control means 8, which has received the signal, outputs an output signal to the illumination lamp 7B to turn on all the illumination lamps 7B and illuminate the lower surface of the automobile A.

  Since the lower surface of the vehicle is illuminated in this manner, the lifting point of the vehicle A can be easily set on the lift receiving portions of the fixed lift 2 and the movable lift 3 even if the lower portion of the vehicle A is difficult to see. At this time, even if the LED light source of the illumination lamp 7B directly emits light, the translucent plate 7C prevents glare and improves the setting work efficiency. In order to further facilitate the setting operation, the illuminance adjusting means 9 is operated to adjust the illuminance of the illumination lamp 7B via the control means 8, or the irradiating direction adjusting means 10 is operated. The irradiation direction of the illumination lamp 7B may be adjusted via the control means 8. In this case, the illumination lamp 7B is pivotally attached to the bottom surface so that the irradiation direction can be adjusted.

  When the vehicle A is lifted up and the equipment on the bottom surface of the vehicle A is inspected and maintained, the work is facilitated and the work efficiency is improved because the structure on the bottom surface is illuminated by the illumination lamp 7B.

  When the lift is lowered and the car A leaves the place of the lift after a series of inspection and maintenance is completed in this way, the signal from the detection means 11 is not output and the illumination lamp 7B is turned off.

  In the above-described embodiment, an example in which the fixed lift 2 and the movable lift 3 are provided in the pit 1 has been described. However, in other lifts such as a two-post lift, the illumination means may be provided near the lift. .

  INDUSTRIAL APPLICABILITY The present invention is used for efficiently performing vehicle lift-up and inspection / maintenance work in automobile manufacturing or inspection / maintenance.
