Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to the field of tow trucks used for transporting automobiles by lifting the front part of a vehicle that is damaged or illegally parked.

[0002]

[Prior art]

 This will be described with reference to FIG. A tow truck is known which is provided with an arm piece 20 that pivots an arm piece 20 axially attached to a rear end of the luggage carrier 10 by a base shaft 13 from a substantially upward position A to a substantially rear downward position B.

[0003]

[Problems to be solved by the device]

 The conventional tow truck shown in FIG. 9 has a drawback that the amount of protrusion C protruding rearward from the rear end 14 of the loading platform 10 is large when the arm piece 20 is raised. Further, when the arm 20 is lowered, the horizontal distance D in the front-rear direction from the rear axle 11 to the base axle 13 is large, and the weight of the automobile 70 to be indexed may cause an insufficient load on the front wheel 15 of the tow truck. It was This invention aims to reduce the amount of protrusion C of the arm piece and reversibly reduce the horizontal distance D from the rear axle 11 to the base axle 13 in the front-rear direction.

[0004]

[Means for Solving the Problems]

 The first device will be described with reference to FIGS. 1 to 8. The tow truck according to the first invention is provided with a forward facing notch 12 at the center of the rear part of the luggage carrier 10, and a lateral base shaft 13 provided in the notch 12 is rotatably movable in a range from substantially upward to substantially backward. On the contrary, a rotation drive device 40 that pivotally supports the base end of the V-shaped arm piece 20 and has an automobile lower surface hooking tool 30 at the tip of the arm piece 20 to rotate the arm piece 20 from a substantially rearward position to a substantially upward position. Was set up.

In the second invention, a rotation driving device 40 for rotating the arm piece 20 in the first invention from a substantially rearward position to a substantially upward position pivotally supports the front upper end of the arm piece 20 on the base shaft 13, and A telescopic hydraulic cylinder 62 is arranged between a laterally-oriented pivot 61 provided on the luggage carrier 10 in front of the rear axle 11 and near the base end of the arm piece 20.

A second device will be described with reference to FIGS. 5 to 8. In the second invention, a rotation drive device 40 for rotating the arm piece 20 in the first invention from a substantially rearward position to a substantially upward position is provided with a front end of an upward convex V-shaped arm 50 on the loading platform 10. The lower end of a vertical hydraulic cylinder 51, which is pivotally attached and has its upper end pivotally attached to the top of the middle of the V-shaped arm 50, is pivotally supported on the cargo bed 10 by bending the rear end of the V-shaped arm 50 and the arm piece 20. The part 21 is connected via a link 52.

[0007]

[Action]

 From the state shown in FIGS. 1 and 5, the arm piece 20 is lowered as shown in FIGS. 2 and 6, and then the tip of the arm piece 20 is moved to a position where the front wheel 71 of the automobile is lifted. The hydraulic cylinder 51 or the telescopic hydraulic cylinder 62 is slightly shortened to slightly lift the front part of the vehicle. Index with the front of the car slightly lifted.

【Example】

 A first embodiment will be described with reference to FIGS. 1 to 4. A front notch 12 is provided in the center of the rear part of the luggage carrier 10. A base end of a rotatably movable inverted V-shaped arm piece 20 is axially supported by a lateral base shaft 13 provided corresponding to the cutout portion 12 in a range from substantially upward to substantially rearward. An automobile lower surface hooking tool 30 is provided at the tip of the arm piece 20, and the upper end of the front portion of the arm piece 20 is pivotally supported by the above-mentioned base shaft 13. A telescopic hydraulic cylinder 62 is arranged between a laterally-oriented pivot shaft 61 provided on the luggage carrier 10 located in front of the rear axle 11 and near the base end of the arm piece 20 to form a rotary drive device 40.

A second embodiment will be described with reference to FIGS. 5 to 8. A front notch 12 is provided in the center of the rear part of the luggage carrier 10. The base end of the rotatably movable inverted V-shaped arm piece 20 is axially supported by the lateral base shaft 13 corresponding to the notch 12 in a range from substantially upward to substantially rearward. An automobile lower surface hooking tool 30 is provided at the tip of the arm piece 20, and the front end of an upward convex V-shaped arm 50 is pivotally attached to the luggage carrier 10. The lower end of a vertical hydraulic cylinder 51 whose upper end is pivotally attached to the top of the middle of the V-shaped arm 50 is pivotally supported on the loading platform 10, and the rear end of the V-shaped arm 50 and the bent portion 21 of the arm piece 20 are connected. They are connected via a link 52 to form a rotation drive device 40.

In any of the first and second embodiments, it is possible to attach the auxiliary hydraulic cylinder 22 to the arm piece 20 and provide the hook 30 at the tip of the auxiliary hydraulic cylinder 22.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and various modifications can be made within the scope described in the scope of claims for utility model registration.

[0012]

[Effect of device]

 According to this invention, the amount of protrusion C of the arm piece 20 can be reduced and the horizontal distance D in the front-rear direction from the rear axle 11 to the base axle 13 can be reversibly reduced. Therefore, the size is reduced and stability is improved.
