Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vehicle holding device used to lift and move a variety of completed vehicles such as passenger cars.

Since current passenger cars are mainly made of thin plate structures,
If the vehicle body is lifted during movement, the vehicle body will be damaged.

Therefore, considering the structure of a passenger car, the only points that can support the load during movement are the wheels and the jack-up point.

However, the position of the jack-up point varies considerably depending on the type of passenger car, and it is therefore difficult to use the same device for many types of cars.

Therefore, the current situation is that pallets are unavoidably placed under wheels and then lifted by appropriate means such as forklifts or cranes and moved to other locations.

The present invention utilizes wheels that support the weight of the vehicle itself, such as a passenger car, and at the same time can sufficiently withstand various resistances during running, and enables vehicle holding that allows operations such as lifting and moving to be carried out easily and safely. This device was created for the purpose of providing a device that includes a plurality of slide beams that slide in mutually opposite directions approximately parallel to the center line of the vehicle, and is connected to the tips of the slide beams so that they can rotate horizontally. Attach the arm, fix brackets to both ends of the connecting arm, and fit one end of the wheel support arm into a long hole provided at the tip end of the bracket so that it can move in a direction parallel to the slide beam. The other end of the wheel support arm support, whose end is pivoted to the middle part of the wheel support arm, is pivoted to the connecting arm side of the bracket, and the end of the wheel support arm is pivoted to the elongated hole side end and the expanded elongated hole side end. The present invention is characterized in that a support member for supporting the wheels of the vehicle is attached to each of the brackets, and a guide roller is provided at the tip of the bracket.

Embodiments of the present invention will be described below with reference to the drawings.

Guides 2 and 2' having a box-shaped cross section are mounted on the telescopic fork 1, which is formed to be expandable and retractable by an appropriate means in a direction substantially perpendicular to the longitudinal direction (centerline direction) of the passenger car C. The guide 2 is fixed substantially parallel to the longitudinal direction, and
Slide beams 3, 3' having a box-shaped cross section are fitted into the slide beams 2', and another slide beam 4° 4' is fitted into the slide beams 3, 3'.

Further, elongated holes 5, 5' are provided on the side surfaces of the guides 2, 2' along the guides 2, 2', and the slide beam 3'
The bracket 6 fixed to the side surface of the guide 2' is connected to the elongated hole 5 of the guide 2'.
′ protrudes outward.

A hydraulic cylinder 7 operated by a hydraulic unit (not shown) is disposed between the guides 2 and 2', and the tip of the hydraulic cylinder 7 is pivotally connected to the bracket 6 with a pin. The body of the cylinder 7 passes through the long hole 5 of the guide 2 and is fixed to the side surface of the slide beam 3.

A support arm 9 is pivotally attached to a support arm 8 provided on a bracket at the tip of each of the slide beams 3, 4' and 3', 4 so as to be able to swing up and down. It is not rotated downward from the horizontal position and is held horizontally in the normal state by means of appropriate means such as a stopper.

A bracket 10 integrally fixed to the support arm 9 is provided with a support pin 11 inserted in the vertical direction, and a connecting arm 12 is attached to the support pin 11 substantially parallel to the telescopic fork 1.
to be pivoted.

The connecting arm 12 can swing left and right on a horizontal plane, but the range of swing is regulated by appropriate means.

Brackets 13 are fixed to both sides of the connecting arm 12, and one end of a substantially inverted wheel support arm 15 is pivotally connected to a long hole 14 provided at the tip of the bracket 13. One end of a wheel support arm support 16 is pivotally connected to the curved portion at approximately the center of the wheel support arm support 16 , and the other end of the wheel support arm support 16 is pivotally connected to the bracket 13 .

There are a pair of left and right wheel support arms 15 and a pair of wheel support arm supports 16 for one wheel, and at both ends of the pair of left and right wheel support arms 15 there are support members 17 that directly support the wheel.
．． 18 is mounted to connect the wheel support arm 15.15.

Further, one end of a spring 19 is engaged with the upper side of the wheel support arm 15, and the other end of the spring 19 is fixed to the tip of the connecting arm 12.

In the figure, 20 is a tip guide roller pivotally attached to the tip of the bracket 13; 21. ．． 2L is the wheel of passenger car C,
P is pit.

When the passenger car C is placed at a predetermined position on the pit P with the brake or gear applied, the telescopic fork 1 extends from the side of the passenger car C, and the vehicle holding device It reaches the predetermined position at the bottom of C.

Next, when the hydraulic cylinder 7 is extended, the slide beams 3, 4' and 3', 4 are extended in opposite directions, respectively.
As shown in FIGS. 8 and 9, when the bracket 13 is slightly below the top surface of the pit P, the tip guide roller 20 contacts the end of the pit P and rotates slightly upward about the support arm pin 8. move.

Furthermore, when the slide beams 3, 4' and 3', 4 extend, the horizontal positions of the passenger car C and the wheel support arms 15 are slightly deviated from the predetermined positions. 21-1 to 21-4, a predetermined set of them first contacts the wheels, and then the other wheel support arms 15 sequentially contact other wheels.

For example, assume that the slide beams 3, 4' and 3', 4 are extended and one set of the wheel support arms 15 comes into contact with the wheel 21-1.

Then, the wheel support arm 15 that came into contact with the wheel 21-1
does not move forward any further, but since the slide beams 3, 4' and 3', 4 still move forward, the wheels 21. ．． 21. The connecting arm 12 on the side rotates around the support pin 11, and the wheel support arm 15 on the side of the wheel 212 rotates around the support pin 11.
come into contact with.

Also wheels 21. , 212 and the wheel support arm 15, the slide beams 3, 4' will not extend any further, but the slide beams 3', 4 will not extend as much as the wheels 2'L3, 21 . extends until it makes contact with.

Even if all four sets of wheel support arms 15 are in the state shown in FIG.
When a force is applied to the wheel support arm 15, the wheel support arm 15 moves along the elongated hole 14.

Then, the wheel support arm support 16 rotates upward, and the wheel support arm 15 also rotates upward, and the support member 1
7.18 are the wheels 21. ．． Complete contact with 2L.

When such a state is reached, the operation of the hydraulic cylinder 7 is stopped, the telescopic fork 1 is raised, and the passenger car C is moved.

When the passenger car C is to be taken down from the vehicle holding device, the telescopic fork is lowered, the hydraulic cylinder 7 is activated, and the slide beams 3.4', 3', and 4 are shortened.

In this case, since the wheel support arm 15 is provided with a spring 19, as the hydraulic cylinder 7 is shortened, the wheel support arm 15 moves in the opposite direction along the elongated hole 14 and returns to its original position.

In the embodiments of the present invention, the case where the vehicle holding device is used for a passenger car has been described, but it is understood that the vehicle holding device can be used for any vehicle, not just a passenger car. It goes without saying that the present invention may be implemented by installing the vehicle on the vehicle, and that various other changes may be made without departing from the gist of the invention.

Since the vehicle holding device of the present invention has the above-described configuration, it can: (1) Support the dead weight of a vehicle such as a passenger car near the area directly below the wheel shaft of the vehicle, thereby preventing excessive force from being applied to the vehicle shaft; Since no force is applied to the vehicle, no excessive lateral force is applied to the vehicle, and the wheel support arms prevent the vehicle from moving laterally, transportation can be carried out safely and reliably.

■) Applicable to various vehicles with different wheel bases.

■) By extending and contracting the slide beam and rotating the connecting arm in the horizontal direction, it is possible to lift the vehicle even if the vehicle holding device is not at the center of the wheelbase, or even if the center line of the vehicle wheelbase and the vehicle holding device are not parallel to each other. You can move.

■) Since the support arm is configured so that it can be raised and lowered, when supporting a wheel, the support arm can be erected to support the wheel in a stable state, while when not supporting a wheel, the support arm can be lowered down. This allows the entire device to be lowered, making it possible to use it even on vehicles with a low lower body.

(2) Since a guide roller is provided at the tip of the bracket to which the support arm is attached, the load of the support arm, connecting arm, etc. is not applied to the slide beam, and the slide beam can slide smoothly.
