Description

[Detailed Description of the Invention] [Object of the Invention] The present invention relates to a vehicle carrier, and may damage a vehicle body during transportation such as wire or chain hooking without driving the vehicle itself to be transported. In a transport device that does not require high-performance means, the vehicle body is equipped with a low posture as an effective loading space, and yet a simple, quick and accurate transport state is formed, and it is possible to immediately respond to transport of various target vehicles. It is a thing.

(Industrial field of application) Conveying devices for various vehicles such as broken cars, infringing cars, and repaired cars.

(Prior Art) With the recent development and popularization of transportation facilities or vehicles, accidents have increased in number, and it is often necessary to transport a damaged vehicle to a repair shop or the like. Further, it is often necessary to remove and transfer illegally parked vehicles on the road, and in such cases, so-called wreckers are used. That is, the front wheels or the rear wheels of a vehicle are placed on a towing vehicle, or the entire vehicle is loaded on a transport vehicle and transported.The method of forming the transport state is to use a crane provided on the chassis to drive the target vehicle. It is intended to suspend and operate the vehicle, or to drive the target vehicle into the pedestal formed on the transportation vehicle to enter the vehicle, and to connect and restrain the vehicle with a wire or the like for transportation.

In addition, various vehicles such as a front-rear drive method and a rear-wheel drive method have been put into practical use as vehicles in recent years.

(Problems to be solved by the invention) Among the above-mentioned conventional ones, in which a target vehicle is suspended by a crane provided on a chassis, a crane arm or the like has a high posture, and a mechanism for transportation is used. The whole body inevitably has to be large and high. In addition, since it requires wire hooking and chain hooking, the number of man-hours required to form the transport state is large, and it requires a considerable amount of time, and traffic congestion is inevitable due to the handling of accident vehicles on highways. Absent. Moreover, there is a high possibility that the vehicle body will be damaged due to the operation such as the wire hanging, and the high-position carrier vehicle is restricted from entering the inside of the tunnel or the like.

In order to enter the target vehicle by operating the cradle formed on the carrier vehicle, the cradle is lowered to the grounding state and the front side or rear wheel side of the target vehicle is advanced, and then the Since the target vehicle is restrained and transported by raising the pedestal and wire hooking, etc., the transport vehicle itself has a relatively low posture, but it is often impossible to drive in an accident vehicle etc. The driving must be operated manually or by the power of another vehicle, and the man-hours required for that are significant. Further, a considerable amount of man-hours and time are required for connection restraint such as wire hanging after the target vehicle has entered the cradle.

In addition, there are various vehicles that should be actually moved, and even if the vehicle is driven by supporting the drive wheels on the pedestal and goes up, if the engine key is removed after stopping in a front-and-rear wheel drive type vehicle. Cannot move even if one of the drive wheels is lifted by a tow truck, and travels by receiving either one of the drive wheels or a support base that holds the vehicle body in a raised state even when the vehicle for corner transport arrives. There is the disadvantage of having to be accompanied by another vehicle, such as carrying a trolley or the like to form the enabled state.

[Constitution of device] (Means for solving the problem) A towing vehicle for transporting a target vehicle, wherein a holding area formed by bending and hanging in an L shape is formed at a tip end portion of a crane arm provided on the towing vehicle.

However, the length of the towing arm 2 adapted to the size and type of the target vehicle 6 is adapted so that the vehicle bodies can be separated from each other even when the towing vehicle 1 and the target vehicle 6 are turned right or left during transportation. Although it is arranged so as not to come into contact with each other, it is a matter of course that the pulling arm 2 may be an integral unit if the pulling arm 2 can be kept as long as it is. The above-mentioned connecting seat 3 is provided with a rotation restricting portion 31 on both sides as shown in FIGS. 3 and 4, and the connecting seat 3 and the receiving frame 4 rotate excessively in the horizontal direction. It is preferable to avoid contact between the two vehicle bodies 1 and 6. That is, in the structure shown in FIG. 4, the receiving frame 4
On the other hand, in FIG. 4, the connecting seat 3 provided so as to be rotated in the vertical direction is 120 ° in the left-right direction about the shaft 9.
The rotation is stopped within a range of (240 ° in total), and at the rotation limit, the limiting portion 31 is joined to the step portion 32 formed near the connecting portion 8 of the inner pipe 21, and the rotation is stopped. Is made to be done. Further, the connecting portion 8 is formed as a turntable-shaped disc centered on the insertion hole of the shaft 9 and prevents the target vehicle 6 from rolling even when the connecting seat 3 and the receiving frame 4 are rotated. It is designed to be transported in a stable state.

The locking rod 41 of the wheel receiving portion 40 of the receiving frame 4 has a structure for transporting the target vehicle 6 without operating it. In the illustrated one, the tip of the locking rod 41 is used. Are inserted into and removed from the receiving holes 43 formed in the intermediate protrusion 42 from both sides, and the locking rod 41
The connecting pin 44 provided at the base end of the receiving frame 4 is formed so that it can be inserted into and removed from the locking holes 45 formed on both outer sides of the receiving frame 4, and the locking rod 41 is slid to insert its tip into the receiving hole 43. The connecting pin 44 can be fixed by inserting it into the locking hole 45. However, in this configuration, it is sufficient that the locking rod 41 can be fixed to the wheel receiving portion 40, and in particular, when the target vehicle 6 is towed and transported, about one half of the weight of the target vehicle 6 is the wheel. Since the receiving portions 40 and 40 are loaded, it is essential that the specific structure as described above, that is, the locking rod 41 is locked to the receiving hole 43, the locking pin 44 and the locking hole 45. It is clear that this is not what you want. That is, the fourth
As shown in the figure, it is obvious that the engaging parts 46 may be formed on both sides of the wheel receiving part 40 so that both ends of the locking rod 41 are locked, and in the case of such a configuration of FIG. It is not necessary to slide the locking rod 41 from the outside of the wheel receiving portion 40 to mount and dismount it. This means that the target vehicle, such as a parking violation, is generally parked near the border of the pedestrian path,
That is, it is usual that boundary blocks are lined up at the boundary part of the pedestrian road and the sidewalk side is high. Under such conditions, the locking rod 41 cannot be inserted and removed in contact with the roadway surface. Although it is usual, it is obvious that the structure shown in FIG. 4 allows the locking rod 41 to be properly mounted / dismounted even under the condition of being close to the pedestrian road boundary block. It is clear that stable traction and transportation can be achieved under the condition of loading about half of the weight of the target vehicle 6.

An engaging member 17 is provided at an intermediate portion of the towing arm 2 as shown in FIG. 3, while an engaging hole 46 is provided at an intermediate portion of the receiving frame 4.

When the tow arm 2 is erected while the receiving frame 4 is fixedly connected to the towing arm 2 in this manner, the receiving frame 4 is sandwiched between the vehicle body of the towing vehicle 1 and the towing arm 2, and As shown in FIGS. 1 and 2, the compact folding of the vehicle body surface allows the vehicle to travel freely as a low-profile vehicle, and also has a chassis 1 for devices and articles loaded on the chassis 12.
2, 12 to prevent falling off behind.

Further, rising side wall portions 16 are formed on the sides of the chassis 12 to prevent the devices and articles loaded on the chassis 12 from falling off to the side. That is, the standing state of the receiving frame 4 by the pulling arm 2 and the rising side wall portion 16 allow the chassis 12 to be used as a loading area for effective devices and the like.
That is, for example, even if the illegally parked vehicle is a front-rear wheel drive system and the jack is loaded on the chassis 12 even under the condition that the engine key does not exist, or from the tip of the tow arm in the virtual line state shown in FIG. As shown in FIG. 5, a crane mechanism using wires drawn out from the corners of the crane arm is appropriately used to hoist the target vehicle. Further, on the chassis 12, there may be loaded a support for supporting the bottom of the target vehicle and a trolley for receiving wheels in a locked state so as to be able to run, and the target vehicle in which each wheel is locked as described above may be appropriately used. Can be transported to.

[Advantages of the Invention] According to the present invention as described above, the wheels of the target vehicle can be received and conveyed in the wheel receiving portion without using a crane, and the towing vehicle can be in a low position. Well, it can be effectively used even in a tunnel or other conditions where the height is limited. Moreover, it is not necessary to drive the target vehicle, and the transport state can be maintained under the condition that the target vehicle is stopped. It is obvious that the crane arm can be formed, but since the crane arm is held by the holding rollers, the operation is stable regardless of its lifting operation, and the tow arm attached to the crane arm is the target vehicle. It is used not only for towing, but also for crane operation, and it is also used as an effective loading area for equipment, etc., due to the receiving frame that is folded on the chassis and the rising side wall on the side of the chassis. Since it can be used, it has the effect that it can be loaded with jacks, support bases, trolleys, etc., and it can be properly transported to any target vehicle. .
