Sprockets are mounted on the motor shafts of the rotating shaft 72 and the motor 73, and both sprockets may be coupled by a single chain.

Thus, the rotating shaft 72 is rotated in a direction corresponding to the rotational direction of the motor shaft.

Since the first rack bar 521 and the second rack bar 68 are arranged side by side, the pinion gear 71 is arranged in the order of the first rack bar 521 and the second rack bar 68 according to the rotation direction or number of rotations of the motor 73. ) Or, the second rack bar 68 and the first rack bar 521 are engaged with the pinion gear 71 in order, whereby the first movable lift guide unit 52 is engaged with the second movable lift guide unit 53 ) is drawn in or drawn out from the lead-in space.

Meanwhile, the aforementioned second rack bar 68 may be divided into a first area 681 facing the first rack bar 521 and a second area 682 integrally formed on one side of the first area 681. there is. Also, the first region 681 and the second region 682 have a stepped structure, and the first region 681 is formed at a higher position than the second region 682 . In this case, the first region 681 may be formed in a shape in which an inclination angle gradually increases from one end in contact with the second region 682 to the other end.

Next, operations of the lifting guide unit 50, the traction unit 60, the pull-out driver 90, and the drive unit 70 described above will be described.

First, when loading or unloading a vehicle, which is an object to be loaded into the loading unit 2a, hydraulic pressure is supplied to the pull-out drive unit 90 to advance the piston. When the piston moves forward, the second movable lift guide unit 53, which has been drawn into the inlet space of the fixed lift guide unit 51, is pulled out.

Thereafter, the motor 73 is operated to rotate the motor shaft in the forward direction (clockwise direction).

When the motor shaft is rotated, the rotating shaft 72 and the pinion gear 71 are rotated in the forward direction, and as a result, the first rack bar 521 moves along the pinion gear 71 so that the first movable lift guide unit 52 It is moved in a direction drawn out of the second movable lift guide unit 53.

And, when the first rack bar 521 passes the pinion gear 71, the second rack bar 68 then moves a predetermined distance further along the pinion gear 71, and as shown in FIGS. 1 and 5, the first movable lift guide The unit 52 is completely drawn out of the second movable lift guide unit 53.

At this time, when the first movable lift guide unit 52 is withdrawn from the second movable lift guide unit 53, it is rotated downward with respect to the mounting member 522 by its own weight.

In addition, the first movable lift guide unit 52 is completely drawn out of the second movable lift guide unit 53 so that the first movable lift guide unit 52 is at the end of the second movable lift guide unit 53. When positioned, the pinion gear 71 is engaged only with the gear teeth of the second area 682 among the gears of the second rack bar 68, or the gear teeth of the first area 681 and the gear teeth of the second area 682. It can be jointly meshed with gear teeth.

Therefore, the edge plate 523 is seated on the ground, and the fixed lift guide unit 51, the first movable lift guide unit 52, and the second movable lift guide unit 53 maintain a certain inclination angle to form an inclined plane on the vehicle. By providing a lift path, it is possible to easily load a vehicle on the loading part 2a or lower it to the ground.

In particular, as described above, since the first area 681 and the second area 682 are formed in a stepped structure and the first area 681 is disposed at a higher position than the second area 682, the first area 681 and the second area 682 are formed. The movable lift guide unit 52 is located at the end of the second movable lift guide unit 53, and the pinion gear 71 is only the gear teeth of the second area 682 among the gears of the second rack bar 68. When engaged or jointly engaged with the gear teeth of the first area 681 and the gear teeth of the second area 682, the left side of the traction part 60 is inclined downward with reference to FIGS. 6 and 8 The right side of the traction part 60 is tilted upward so that the first moving part 66 comes into contact with the bottom surface 531 of the second movable lift guide unit 53, and the second moving part 67 moves the second moving part 67 to the second moving part 67. It comes into contact with the ceiling surface 532 of the movable lift guide unit 53. In addition, since the rotary mount is located on the side of the second moving part 67 that comes into contact with the ceiling surface 532 of the second movable lift guide unit 53, it rises to a predetermined height, and eventually see FIG. 6. As a reference, a certain area on the upper left side of the first movable lift guide unit 52 connected to the pivoting fixture via the mounting member 522 is raised to a predetermined height in the upward direction.

As a result, as shown in FIG. 8, since the inclination angle of the first movable elevation guide unit 52 is lower than the inclination angle of the second movable elevation guide unit 53 and becomes gentle, the vehicle moves from the ground to the first movable elevation guide unit ( 52), it is possible to prevent the bumper of the vehicle from colliding with the first movable lift guide unit 52.

Of course, even in the process in which the vehicle located in the loading unit 2a sequentially passes through the second movable lift guide unit 53 and the first movable lift guide unit 52 to come down to the ground, the bumper of the vehicle does not collide with the ground. It can be prevented.

Furthermore, even in the case of a vehicle with a low body such as a sports car, it is possible to prevent the lower part of the vehicle (fender) from colliding with the first movable lift guide unit 52.

On the other hand, the support part 10 is disposed on the loading part 2a of the transfer equipment 2 to support the vehicle.

The rotation member 11, the first support member 12, and the second support member 13 described above may be formed of a material having excellent durability and rigidity such as metal or stainless steel so as not to be bent or deformed by the load of the vehicle. there is.

Additionally, since the distance between the front tire and the rear tire is different depending on the size of the vehicle, such as a compact car, a mid-size car, a sedan, or an SUV, the first support member 12 and the second support member 13 are respectively rotated by the rotation member 11 It can slide along the upper surface of.

Due to this, the first support member 12 and the second support member 13 may be moved in a direction closer to or farther from each other.

Therefore, it is possible to adjust the distance between the first support member 12 and the second support member 13 according to the size of the vehicle, and the first support member 12 and the second support member 13 are added to the support unit 20. Spacing can be optionally adjusted for

The first support member 12 and the second support member 13 whose intervals are adjusted in this way may be fixed to the rotation member 11 by a position fixing unit (not shown).

Although not shown in the drawing, a plurality of position variable holes (not shown) are formed at regular intervals on the upper surface of the pivot member 11, and position variable holes are formed in the first support member 12 and the second support member 13. Connection holes (not shown) corresponding to may be formed, respectively.

A plurality of position fixing parts are applied to the position variable hole of the pivot member 11 and the connection hole of the first support member 12 and the position variable hole of the pivot member 11 and the connection hole of the second support member 13, respectively. inserted jointly. Due to this, it is possible to fix the first support member 12 and the second support member 13 to the rotation member 11 after the distance adjustment is completed.

Then, the position fixing unit is sequentially inserted into the connection hole and each position variable hole from above the first support member 12 and the second support member 13 .

At this time, the position fixing part may be formed of a known bolt. Although not shown in the drawings, lower portions of the position fixing parts may each protrude toward the lower side of the pivoting member 11 .

Therefore, the first support member 12 and the second support member 13 may be stably fixed to the pivot member 11 by fastening a nut on the lower side of the position fixing unit.

Meanwhile, the additional support part 20 is configured to jointly support the vehicle together with the support part.
