Description

[Detailed description of the invention] This invention relates to an autolift for lifting vehicles.The purpose of this invention is to make it compatible with vehicle lifts of different sizes by a simple setup change operation of the vehicle cradle. It is to do so.

Generally, there are two types of autolift vehicle cradle: plate type and swing arm type. The plate method has the advantage of being able to lift a vehicle simply by placing the vehicle on the plate, but since the length and width of the cradle are fixed, the size of the vehicle that can be lifted is naturally limited. There are some drawbacks. On the other hand, the swing arm system has the advantage of being able to adapt to the size of the vehicle by rotating and extending/contracting the arm, but the swing arm must be released when the vehicle is being driven into the vehicle. Each time the vehicle is entered, the swing arm must be rotated and extended or retracted to a position where the vehicle can be supported, which makes the operation extremely troublesome.

The present invention aims to provide an autolift in which both the length of the pedestal and the width between the pedestals can be changed through simple setup changes while taking advantage of the advantages of the plate type vehicle pedestal.

An example in which an embodiment of the present invention is applied to an underground autolift will be described below.

In FIG. 1, reference numerals 10 and 11 indicate a pair of lift cylinders buried underground at a predetermined interval, and rams 12 and 13 as lifting members can be moved up and down in these lift cylinders 10 and 11. is fitted in. A pair of plate-shaped vehicle pedestals 14 and 15 are attached in parallel to the upper ends of the rams 12 and 13, and the lower portion of the vehicle body between the front and rear wheels of the vehicle is supported on these vehicle pedestals 14 and 15. Rack shafts 16 and 17 are connected to the vehicle supports 14 and 15 in parallel with the rams 12 and 13, and pinions 18 and 19 that mesh with these rack shafts 16 and 17 are fixed on a synchronizing shaft 20, and these rack pinions and A synchronization mechanism consisting of a synchronization shaft synchronizes the vertical movement of the pair of vehicle pedestals 14 and 15. The above is the general configuration of an underground autolift.

Next, the main parts of the present invention will be explained.
It consists of movable plates 23, 24, 25, and 26 provided at the front and rear of each of 1 and 22 so as to be slidable in a direction inclined with respect to the direction of entry of the vehicle (in the direction of the arrow). That is, inclined guide surfaces 27 (see FIG. 2) that intersect inside each vehicle cradle 14, 15 are formed at the front and rear of the fixed pedestals 21, 22, respectively.
Movable plates 23, 24, 25,
26 are slidably engaged. Movable plate 2
3, 24, 25, and 26 are formed with elongated holes 28 along the inclined guide surfaces 27, and the movable plates 23, 24, 25, 26 can be fixed to fixed plates 21, 22 at arbitrary positions. Note that 33 and 34 are sheet pads made of an elastic material such as synthetic rubber that are fixed to the upper surfaces of the fixed plates 21 and 22 and the movable plates 23, 24, 25, and 26.
It is attached to the part that touches the bottom of the car body.

By adjusting the slides of the movable plates 23, 24, 25, 26 in the inclination direction, the vehicle cradle 14, 1
The pedestal length dimension L and the pedestal width dimension W of No. 5 can be changed simultaneously in a proportional relationship determined by the inclination angle of the inclined guide surface 27. That is, as the length of the pedestal increases (decreases), the width between the pedestals also increases (decreases).

Since the autolift of the present invention is constructed as described above, for example, when used for lifting an ordinary passenger car, the movable plates 23, 24, 25, 26 are replaced with the fixed plates as shown by the solid lines in FIG. 21,2
Fix it in a position consistent with 2. In this case, the length dimension of the vehicle pedestals 14 and 15 is L, and the width dimension between the pedestals is W. Next, when lifting a small vehicle such as a light car, loosen the tightening bolt 29 and move the movable plates 23, 24, 25, 26 along the inclined guide surface 27 so that one end of the elongated hole 28 is connected to the tightening bolt. Slide the movable plates 23, 24, 25, 26 inward to the position where they lock on the movable plates 23, 24, 25, 26 and tighten the tightening bolts 29.
are fixed to the fixing plates 21 and 22 again. Only by adjusting the slides of these movable plates 23, 24, 25, 26, the length and width dimensions of the vehicle pedestals 14, 15 can be changed to L-△L and W-△W, which are suitable for light vehicles. . Conversely, when lifting a large vehicle such as a truck, movable plates 23, 24,
25 and 26 outward along the inclined guide surface 27 until the other end of the elongated hole 28 engages with the tightening bolt 29, the length and width of the vehicle holders 14 and 15 are increased ( L+△L, W+△W). In addition, for vehicles whose structure cannot directly support the vehicle body on the vehicle cradle 14, 15, the vehicle cradle 1
Attachments may be attached to 4 and 15 to support them.

FIGS. 3 and 4 show another embodiment of the present invention, in which the same functions as the previous embodiment can be achieved with a simpler configuration.

That is, the movable plate 124 is made into a thin plate, and the movable plate 124 is superimposed on the supporting parts 121a protruding from both ends of the fixed plate 121 so as to straddle this supporting part 121a, and an inclined length is formed through which the tightening bolt 29 passes. The movable plate 124 can be slid in the inclination direction using the hole 28 as a guide.

In the above embodiment, an underground type autolift was explained, but the present invention can of course be applied to an above-ground type two-post autolift.

As described above, the vehicle cradle of the present invention is composed of a fixed plate and a movable plate that can be slid in the direction of inclination intersecting the fixed plate in front of and behind the fixed plate. Therefore, it is now possible to change the length of the pedestal and the width between the pedestals at the same time simply by adjusting the slide of the movable plate in the direction of inclination.This allows an autolift that can be adapted to vehicles of different sizes with simple setup changes. There are features you can get.
