Description

[Detailed Description of the Invention] The present invention relates to the structure of a tow truck for towing a vehicle such as a broken down automobile.

Conventional Retsu cars have a pair of left and right tires or other wheels fixedly mounted on the underframe, and a wheel support section for the towed vehicle is provided at the top of the underframe, so there is a span plate between the wheel support section and the road surface. The wheels of the towed vehicle have to be pushed up to the wheel support part or lifted with a winch, etc., which increases the weight of the towed vehicle and makes handling of the towed vehicle and the towed vehicle troublesome. Since the retsu car supports the towed vehicle by its wheels, if one or both of the left and right wheels at the front or rear of the towed vehicle are damaged, the towed vehicle must be supported. It was hot because I couldn't do it.

On the other hand, the retsu car body is provided with a jacking mechanism for pushing the retsu car body up against the ground, and wheels are removably attached to both left and right sides of the lower surface of the retsu car body, and wheels are attached to both left and right ends of the support base. , proposed a vehicle towing truck that is equipped with a wheel mounting section with inclined treads.

In addition, by removing both wheels from the tow car body, the height of the wheel mounting section with inclined treads can be lowered, making it easier to mount the wheels of the towed vehicle on the wheel mounting section. In this way, the towed vehicle was pushed up using the jack mechanism, and then wheels were attached to the towed vehicle to tow the towed vehicle. Since the wheels of the towing vehicle are mounted on the vehicle itself,
If one or both of the left and right wheels at the front or rear of the towed vehicle are broken, there is an inconvenience in that the towed vehicle cannot be supported.

The present invention follows the concept of the vehicle towing vehicle disclosed in the previous application;
This method is intended to be applicable even when the wheels of the towed vehicle are broken.

For this reason, the present invention provides a support stand horizontally rotatable on the upper surface of the tow car body connected to the towing vehicle, and a jacking mechanism for pushing the tow car body up against the ground. Further, in the vehicle towing retcher in which wheels are removably attached to the left and right sides of the lower surface of the retscar main body, arm members extending in the front and rear directions of the retscar main body are provided at both left and right ends of the support base. The flow arm members are slidably inserted into each other, and the flow arm members are pivotally connected to the support base with removable pins so as to be horizontally rotatable, while the flow arm members are provided with pin holes in the longitudinal direction for replacing the pins. A plurality of holes are formed at appropriate intervals in the arm member, and a means for locking the arm member at an arbitrary horizontal rotation position is provided between the arm member and the support base, and The rear end is provided with a locking part for the towed vehicle.
