Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a loading and unloading assistance device for a vehicle carrier that enables loading and unloading of a vehicle while supporting a tire between a loading platform and the ground.

[0002]

[Prior art]

 Generally, in a vehicle carrier, a tilting frame whose rear end is pivotally supported and tiltable rearward is provided on a chassis, and a loading platform is slidably provided in the tilting frame in the front-rear direction. With the tilting frame tilted rearward, slide the above-mentioned loading platform rearward to bring the rear end of the loading platform closer to the ground so that the vehicle can be self-propelled and loaded onto the loading platform. ing.

[0003] By the way, there is also a vehicle carrier that can load and unload a faulty vehicle that cannot self-propell on a carrier. In the case of such a vehicle carrier, on the carrier there is a space between the carrier and the ground. The tire supporting section has a sliding wheel on the lower side and a tire supporting section for supporting the tire of the above-mentioned damaged vehicle on the upper section, and the above-mentioned tire supporting operation is carried out by a winding or unwinding operation of a wire by a winch device provided on the chassis. It is equipped with an auxiliary trolley that loads and unloads a failed vehicle onto a bed with the tires supported by the section. As the tire supporting portion of the auxiliary truck, there is a tire supporting member formed of two round pipe-shaped tire supporting members that abut the outer peripheral surface of the tire of the defective vehicle at the vehicle front-rear position.

[0004]

[Problems to be solved by the device]

 However, in the tire supporting member as described above, since the outer peripheral surface of the tire is supported by abutting the locally curved surface of each tire supporting member, it can be smoothly supported if the tire itself is not defective, but it is punctured. In a defective vehicle in which the tire itself is defective due to a tire or a burst, the outer peripheral surface of the tire is deformed, so the local contact with each tire support member increases the deformation of the tire, and the outer peripheral surface of the tire increases. As a result, the tires deteriorated and the tires slipped down from between the tire support members and interfered with the ground, and it was impossible to load and unload a faulty vehicle with defective tires onto the bed.

The present invention has been made in view of the above points, and an object of the present invention is to construct a tire supporting portion capable of reliably holding a defective tire between tire supporting members, and to provide a tire having a defect. It is to enable loading and unloading of the bed of a damaged vehicle.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the solution provided by the present invention is a loading and unloading assistance device for a vehicle carrier, which comprises a tilting frame, which is pivotally supported at its rear end and is tiltable rearward, on the chassis. In addition, a loading platform is provided on the tilting frame so as to be slidable in the front-rear direction, and the loading platform is slid rearward while the tilting frame is tilted rearward so that the rear end of the loading platform is slid back. It is premised on a vehicle carrier that enables loading and unloading of vehicles onto and from the platform by bringing the parts closer to the ground. A winch device provided on the chassis has a wheel supporting the tires of the vehicle on the upper part of the vehicle, which has wheels on the lower part that slide between the carrier and the ground. An auxiliary cart for loading and unloading the vehicle with the tire supported by the tire supporting section onto and from the bed by winding or unwinding the wire is provided. Further, the tire supporting member is provided with a tire supporting member that is inclined in a substantially inverted C-shaped cross section so as to hold the outer peripheral surface of the tire from the front and rear direction of the vehicle.

[0007]

[Action]

 With the above structure, according to the present invention, when a defective vehicle such as a motor vehicle is loaded on the bed which is slid backward in the backward tilted state, the wire is rewound by the winch device and one end of the ground vehicle Vehicle), for example, a vehicle-mounted hook at the front end of the vehicle. In this state, the auxiliary carriage is alighted on the ground, and the tires of the vehicle to be loaded are lifted by jacks or the like to be supported by the tire support portion of the auxiliary carriage. The tire support member is supported by a tire support member inclined in a substantially inverted V-shaped cross section so that the outer peripheral surface of the tire abuts on a flat surface so as to embrace it in the vehicle front-rear direction so that it can be smoothly operated. There is. Then, by winding the wire with the winch device and moving the vehicle forward, the auxiliary carriage slides forward in stead of the tire supported by the tire supporting part as the wire is wound, and the vehicle moves forward together with the auxiliary carriage. To complete loading of vehicles from the ground onto the platform.

On the other hand, when the vehicle is lowered from the chassis to the ground, the winch device rewinds the wire, so that the vehicle can be unloaded according to the unwinding amount (deriving amount) of the wire on the loading platform in the backward tilted state. By moving it backwards, the auxiliary truck slides backward instead of the tires, the vehicle moves backwards together with the auxiliary truck, and the vehicle is lowered from the loading platform to the ground. Then, the tire supported on the tire support portion of the auxiliary truck is lifted with a jack to release the support of the tire support portion of the tire, and the work of lowering the failed vehicle from the loading platform to the ground is completed.

As described above, the tire of the automobile to be loaded / unloaded on / from the loading platform holds the outer peripheral surface of the tire from the vehicle front-rear direction by the tire support member that is inclined in the shape of an inverted inverted V in cross section at the upper portion of the auxiliary truck. As described above, the flat surface abuts on the outer peripheral surface of the tire, so that the tire supporting section can smoothly support the contact area with the outer peripheral surface of the tire. In such a case, even in the case of a defective vehicle in which the tire itself is defective due to puncture or burst, the outer peripheral surface of the tire is contacted with the flat surface (inclined surface) of the tire supporting member over a wide range, and the defective outer periphery of the tire is damaged. The deformation of the surface is suppressed, and the holdability of the tire outer peripheral surface with respect to each tire supporting member is improved, and the tire is prevented from sliding down between the tire supporting members and interfering with the ground.

[0010]

[Effect of device]

 As described above, according to the loading and unloading assistance device for a vehicle carrier of the present invention, the outer peripheral surface of the tire is brought into contact with the flat surface of the tire supporting member over a wide range to suppress the deformation of the defective outer peripheral surface of the tire. Therefore, by improving the holding property of the tire outer peripheral surface for each tire support member, it is possible to reliably prevent the interference with the ground due to the slipping of the tire between the tire support members, and to slide the auxiliary truck that replaces the tire. This enables smooth loading and unloading of the failed vehicle onto the bed.

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

FIG. 1 shows a vehicle carrier using an auxiliary loading and unloading apparatus according to an embodiment of the present invention, where 1 is a chassis of a vehicle V connected to the rear of a cabin C, and SC is on the chassis 1. The sub-chassis 2 provided on the tilting frame 2 is pivotally supported at the rear end of the sub-chassis SC so as to be tiltable rearward about the horizontal axis O, and 3 is slidable in the front-rear direction with respect to the tilting frame 2. It is a luggage carrier that can be mounted on the vehicle X supported by the. The loading platform 3 has a deck surface 3a that is formed to have a width that substantially matches the cabin C and extends rearward on the chassis 1, and a frame-shaped front wall 3b that is formed at a height that substantially matches the cabin C. The deck surface 3a includes a rear wall 3d which has a pivot P at the rear end thereof and which opens and closes rearward.

Further, on the rear side of the central portion of the tilting frame 2, the front end of a pair of left and right lift cylinders 4 (only one of which is shown in the figure) having a base end shaft 4a fixed to substantially the central portion of the sub-chassis SC is provided. , And is supported rotatably around the horizontal shaft 5 at this tip portion. That is, when the lift cylinder 4 is extended, the tilting frame 2 is in a tilted state, and when the lift cylinder 4 is shortened, the tilting frame 2 is in a lying state (horizontal state). Further, an extendable telescopic cylinder 6 is linked between the front end of the tilting frame 2 and the loading platform 3, and the loading and unloading operation of the telescopic cylinder 6 causes the loading platform 3 to slide on the tilting frame 2. It is designed to move. When loading and unloading the vehicle X onto the loading platform 3, the loading platform 3 can be smoothly loaded and unloaded, that is, the loading platform 3 has an inclination angle of about 12 ° with respect to the ground. So that the lift cylinder 4 is extended, and in this state, the telescopic cylinder 6 is extended and the loading platform 3 is slid rearward with respect to the tilting frame 2, so that the rear end of the loading platform 3 brought close to the ground is reached. Car X is loaded and unloaded by the department. In this case, the rear wall 3d of the loading platform 3 is opened backward (falling down) when the vehicle X is loaded and unloaded, and its rear end (upper end when closed) is grounded, so that the rear end of the loading platform 3 is It has the function of a walking board that minimizes the difference from the ground.

As a characteristic part of the present invention, as shown in FIGS. 2 and 3, at the center position of the front end portion of the deck surface 3a of the loading platform 3, the wire 11 whose one end is led out is wound or unwound. A possible hydraulic winch device 12 is provided. A hook 13 is fixed to one end of the wire 11, and the hook 13 is engaged with a vehicle-mounted hook 9 provided at the front end of the automobile X. In addition, on the deck surface 3a of the cargo bed 3, the tires FT and RT of the failed automobile X that cannot run on its own are individually supported, and the vehicle X is mounted between the deck surface 3a of the cargo bed 3 and the ground. A plurality of auxiliary carts 15 (only one is shown in the figure) for loading and unloading are provided. The auxiliary carriage 15 has wheels 14, ... Sliding between the deck surface 3a and the ground at four corners in the lower part of the base 10 which is substantially rectangular in a plan view. It is made of solid rubber tires. Further, on the upper portion of the auxiliary cart 15, a tire support for supporting the rear tires RT (only the left side is shown in the figure) of the left and right front wheel tires FT and the left and right rear wheel tires RT of the vehicle X. The section 16 is provided. Then, the auxiliary trolley 15 uses the winch device 12 to wind or unwind the wire 11 so that the rear wheel tire RT is supported on the tire support portion 16 by the vehicle X on the deck 3 of the loading platform 3. The auxiliary truck 15 and the winch device 12 constitute a loading / unloading auxiliary device A for loading / unloading the automobile X onto / from the loading platform 3. Further, the winch device 12 is remotely operated from outside the vehicle V by an operation switch 19, ... On an operation plate 18 connected via a harness 17 to be wound or unwound. There is.

The tire supporting portion 16 has front and rear inclined surfaces 20 and 20 that are inclined in a substantially inverted V-shaped cross section so as to hold the outer peripheral surface of the rear wheel tire RT from the vehicle front-rear direction. It is composed of a pair of tire support members 21 and 21. The gap between the tire supporting members 21 and 21 is a gap (for example, about 200 mm) at which the outer peripheral surface of the tire of any type of automobile does not come into contact with the ground or the deck surface 3a regardless of the burst or puncture state of the tire. ) Is set. The inclined surface 20 of each tire support member 21 is set so as to be inclined at about 30 ° over an inclination range of about 170 mm. The loading / unloading assisting device A then loads the vehicle X onto the deck surface 3a of the loading platform 3 so that the vehicle X supporting the rear tire RT is loaded onto the deck surface 3a of the loading platform 3. When loading, the winch device 12 is rolled up to move the automobile X together with the auxiliary carriage 15 forward, while when the automobile X is lowered from the deck surface 3a of the loading platform 3, the winch device 12 is unwinded. The auxiliary car 15 and the car X are moved rearward. Further, in a transportable state in which the automobile X is mounted on the deck surface 3a, the automobile X is surely fixed on the deck surface 3a by tight binding such as a wire rope (not shown). In this case, the rear wheel tire RT is supported by the tire supporting member 21 of the tire supporting portion 16 under the rear wheel tire RT with the rear wheel tire RT to be supported being lifted by a jack or the like. This is done by locating the auxiliary trolley 15 at.

Here, the procedure for loading and unloading the automobile X onto the loading platform 3 will be described with reference to FIGS. 4 to 6.

First, when loading a faulty automobile X that cannot run on its own on the loading platform 3, as shown in FIG. 4, the lift cylinder 4 is extended to bring the tilting frame 2 into a tilted state, and then the telescopic cylinder 6 is attached. The load carrier 3 is slid rearward with respect to the tilting frame 2 by extending. In this state, the winch device 12 is unwound by the operation switch 19 on the operation plate 18 from the outside of the vehicle to draw out the wire 11, and the hook 13 fixed to one end of the winch device 12 is mounted on the front end of the vehicle X for mounting on the vehicle. The hook 9 is engaged. In this state, the auxiliary truck 15 is lowered to the ground, and the rear wheel tire RT of the automobile X to be loaded is lifted by a jack or the like to be supported by the tire supporting portion 16 of the auxiliary truck 15. The tire support portion 15 is supported by a pair of front and rear tire support members 21 each having an inclined surface 20, 20 inclined in a substantially inverted cross section as shown by a virtual line (dashed line) in FIG. With reference numeral 21, the outer peripheral surface of the rear wheel tire RT is brought into contact with a flat surface so as to be held from the front-rear direction of the vehicle so that the outer surface can be smoothly moved. Then, by winding the wire 11 by the winch device 12 and moving the vehicle X forward, the auxiliary truck 15 replaces the rear wheel tire RT supported by the tire supporting portion 15 with the winding of the wire 11. The vehicle X glides forward and moves the vehicle X together with the auxiliary cart 15 forward to complete loading of the vehicle X from the ground onto the deck surface 3a of the loading platform 3. Thereafter, as shown in FIG. 5, the telescopic cylinder 6 is shortened to slide the loading platform 3 forward with respect to the tilting frame 2, and then the lift cylinder 4 is shortened as shown in FIG. The loading platform 3 together with the tilting frame 2 is brought to the laid-down state, and the defective vehicle is completely mounted on the chassis 1 of the vehicle V in a transportable state.

On the other hand, when the automobile X is to be dismounted from the loading platform 3, after the binding by the wire rope or the like is released, the reverse operation, that is, the lift cylinder 4 is extended and the tilting frame 2 is tilted. After that, the telescopic cylinder 6 is extended and the loading platform 3 is slid backward with respect to the tilting frame 2. In this state, the winch device 12 is unwound by the operation switch 19 to move the automobile X backward according to the unwinding amount (deriving amount) of the wire 11 on the platform 3 in the backward tilted state. As a result, the auxiliary cart 15 slides backward instead of the rear wheel tire RT, and the vehicle X moves backward together with the auxiliary cart 15 to drop the vehicle X from the deck surface 3a of the loading platform 3 to the ground. Then, the rear wheel tire RT supported by the tire supporting portion 16 of the auxiliary truck 15 is lifted by a jack to release the rear wheel tire RT from supporting the tire supporting portion 16, and the deck surface 3a of the luggage carrier 3 is grounded. Complete the work of dismounting car X.

As described above, the rear wheel tire RT of the automobile X that is loaded and unloaded on the loading platform 3 has the inclined surfaces 20 and 20 that are inclined in a substantially inverted V-shaped cross section at the upper portion of the auxiliary cart 15. By contacting the outer peripheral surface of the rear wheel tire RT with a pair of tire supporting members 21 and 21 by a flat surface so as to embrace it from the front and rear of the vehicle, the contact area of the rear wheel tire RT with respect to the outer peripheral surface is increased. In the increased state, the tire support portion 16 can smoothly perform the support. In that case, even in the case of a defective vehicle (automobile X) in which the rear tire RT itself has a defect due to puncture or burst, as shown by the phantom line (two-dot chain line) in FIG. The flat surface of the tire support member 21 contacts the inclined surface 20 of the tire support member 21 over a wide range, so that the deformation of the defective outer peripheral surface of the tire RT for the rear wheel is suppressed, and the rear wheel for the tire support member 21 is prevented. The outer peripheral surface of the tire for tire RT has a good hold property, and the rear wheel tire RT is prevented from sliding down from between the tire supporting members 21 and 21 and interfering with the ground. As a result, loading and unloading of a defective vehicle having a defect in the rear tire RT itself against the platform 3 slid rearward in a tilted state is facilitated by the sliding of the auxiliary truck 15 in place of the rear tire RT. Can be done in

Moreover, since each wheel 14 of the auxiliary truck 15 is formed of solid rubber tires, the sliding of the auxiliary truck 15 is hindered even when the ground is rough or the wheels 14 run on pebbles. It is possible to smoothly absorb the shock without inviting the load and facilitate loading and unloading work.

It should be noted that the present invention is not limited to the above embodiment, but includes various other modifications. For example, in the above embodiment, the tire supporting portion 16 is composed of the pair of tire supporting members 21 and 21, but the integral tire supporting member constitutes a tire supporting portion having a substantially inverted C-shaped cross section with no gap. You may do it.

Further, in the above embodiment, the wheels 14, ... Are provided at the four corners of the auxiliary cart 15, but roller-shaped wheels extending in the left-right direction may be provided at the front and rear positions of the auxiliary cart.

Further, in the above embodiment, the rear wheel tire RT is supported by the tire support portion 16, but the front wheel tire may be supported by the tire support portion. Further, although the vehicle X is loaded on the loading platform 3 from the front wheel tire FT side, the vehicle may be loaded on the loading platform from the rear wheel tire FT side. In this case, The hook at one end of the wire will be engaged with the vehicle-mounted hook provided at the rear end of the vehicle.
