Description

[Detailed Description of the Invention] Field of Industrial Application The present invention relates to an improvement of a vehicle lift.

〓Prior art〓 Vehicle lifts are generally known in which a lifting rod inside a cylinder is moved up and down using fluid pressure such as hydraulic pressure or air pressure. , move the regular position of the plate as the wheel passes over it,
There is a risk of it rotating around the lifting rod.

Conventionally, in order to prevent this rotation of the plate, a guide rod 3 was provided parallel to the lifting rod 2 protruding from the cylinder 1, as shown in FIG. 6, and the guide rod 3 was slidable into the guide tube 4. It has been proposed that the guide rod 3 is fitted in the lifting rod 2, and the guide rod 3 also moves in parallel with the operation of the lifting rod 2, so that the plate 5 does not rotate about the lifting rod 2 as the rotation axis.

Problems to be Solved by the Invention However, the above-mentioned conventional vehicle lift has the drawback that the device is large and heavy, and when the pair of plates 5, 5 shown in FIG. 4 is used, In the conventional device, both plates 5, 5 are reliably raised and lowered from the solid line position without rotating, but for example, the mechanism at the bottom of the vehicle body does not necessarily fit the width of the plates 5, 5, and two points are shown in Fig. 4. In some cases, the width of the plates 5, 5 must be made wider toward the rear of the vehicle body 6, as shown by the chain lines.

In such a case, the conventional rotation prevention mechanism for the plate 5 (shown in FIG. 6) will cause problems.

〓Purpose〓 Therefore, in view of the above-mentioned current situation, this invention prevents the plate 5 from rotating at the normal position when the vehicle body is introduced onto the lift, and allows it to rotate freely during the ascent. The object of the present invention is to provide a vehicle lift which is configured to obtain the above-mentioned characteristics and thereby has improved adaptability to changes in the structure of the vehicle body.

〓Means for solving the problem〓 In line with the above-mentioned purpose, the structure of the present invention, which is summarized in the above-mentioned utility model registration claims, is to solve the above-mentioned problem by adding a rod to the top end of the lifting rod 2 of the cylinder 1. In a vehicle lift in which a plate 5 is fixed and a vehicle body 6 is raised and lowered by raising and lowering the lifting rod 2 via support stands 8 provided at both ends of the plate 5, an upper end flange 11 of the cylinder 1 is provided. A tapered locking pin 10 whose diameter decreases toward the top is provided on the top surface of the
Further, the plate 5 is provided with a locking hole 9 in which the diameter of the lower surface of the plate 5 is enlarged and the locking pin 10 is inserted into the locking hole 9. It is.

〓Operation〓 Therefore, in the vehicle lift of the present invention, the locking pin 10 is in the locking hole 9 when the plate 5 shown in FIG. The plate 5 enters and prevents rotation of the plate 5, but when the lifting rod 2 is raised, the plate 5 is separated from the locking pin 10 and can rotate around the lifting rod 2 as a central axis. .

Embodiments Next, embodiments of the present invention will be described below with reference to the accompanying drawings.

In the drawing, a cylinder 1 is buried under the floor F, and is configured to move the lifting rod 2 up and down by hydraulic pressure, and a plate 5 is installed at the top end of the lifting rod 2.
is fixed via the bolt 7 and the plate 5
A support stand 8 on which the vehicle body is placed is provided at each end of the support stand 8, and a cushion plate 8a is provided on the support stand 8 to serve both as a slip prevention and as a buffer. Note that the top end of the lifting rod 2 is normally fixed at the center of the plate 5, but in order to cope with uneven loads on the vehicle body, it may be fixed near one end of the plate 5 (towards the left and right in Fig. 1). good.

A tapered locking pin 10 whose diameter decreases toward the top is implanted on the upper surface of the upper end flange 11 of the cylinder 1. The locking pin 10 is integrally erected above the screw head, and a screw foot integrally connected to the lower part thereof is screwed into a screw hole provided in the flange 11 and implanted.

Further, the plate 5 is provided with a locking hole 9 whose diameter is enlarged on the lower surface side of the plate 5 and into which the locking pin 10 is fitted.

The height of the aforementioned locking pin 10 may be set as appropriate as long as the plate 5 separates from the locking pin 10 before the support base 8 comes into contact with the lower surface of the vehicle body.
In order to avoid damaging the tires of the car to be introduced, it is desirable that the locking hole 9 not protrude from the surface of the plate 5. Furthermore, in this embodiment, the locking hole 9 is placed on the plate 5 side, and the locking pin 10 is placed on the flange portion 11. It was placed on the side,
A reverse arrangement is also possible.

〓Effect of the invention〓 As mentioned above, according to the present invention, when the car body is introduced onto the lift, it is possible to reliably prevent rotation of the plate by the locking pin, and to prevent the plate from rotating until the plate collides with the car body. During the rise of
It is possible to provide a vehicle lift which has an excellent feature of being able to rotate freely and thus changing the phase of the plate in accordance with the lower structure of the vehicle body if necessary.

In addition, the present invention also includes the installation of the locking pin 10 and the locking hole 9.
This vehicle can be manufactured at low cost because it can be achieved by simply drilling holes in the ground, and it can be installed easily without having to form a bit with a larger and more complicated shape than before for burial. It is possible to provide a lift for use.
