Description

The present invention relates to a vehicle carrier on which a loading platform for loading a vehicle is installed.

Conventionally, a vehicle carrier on which a loading platform for loading a vehicle is installed has been known. In such a vehicle carrier, a vehicle that is not out of order can be self-propelled and placed on the loading platform, or a vehicle that is out of order can be pulled by a winch and placed on the loading platform.

In such a vehicle carrier, the broken vehicle may be pulled up onto the loading platform by a winch while being placed on the vehicle carrier. Although casters are installed on this vehicle carrier to move, the direction of travel is not stable and there is a risk of skewing to the side, which is difficult and dangerous.

Therefore, for example, in the vehicle carrier described in Patent Document 1, a technique of providing a regulation rail for restricting the lateral movement of the casters of the vehicle carrier on the floor surface of the loading platform, or at the rear end of the loading platform. A carrier structure is disclosed in which a guide rail is provided to guide the casters of the vehicle carrier to the center side of the carrier when the vehicle is loaded.

Japanese Unexamined Patent Publication No. 2000-255314

However, since the configuration of Patent Document 1 regulates the movement of casters of a vehicle carrier, it cannot be applied to a vehicle that is self-propelled and loaded on a loading platform. Therefore, in the conventional configuration, the vehicle may come into contact with the lateral tilt.

Therefore, an object of the present invention is to provide a vehicle carrier capable of preventing contact with a lateral tilt even if the vehicle is self-propelled and loaded on a loading platform.

In order to achieve the above object, the vehicle carrier of the present invention is arranged on both left and right sides along the vehicle body having a traveling function, a loading platform installed on the vehicle body for transporting the vehicle, and the loading platform. A detection means installed at the rear end of the lateral tilt and the lateral tilt, which detects that the vehicle is close to the lateral tilt when the vehicle is loaded on the loading platform from the rear side. The rear end of the lateral tilt is provided with a detection means for detecting the vehicle and a notification means for notifying that the vehicle is close to the lateral tilt, and is arranged on both the left and right sides of the loading platform. A notch region open on the rear side and the inward side is formed, and the detection means is configured to detect the vehicle invading the notch region.

As described above, the vehicle carrier of the present invention is a detection means installed at the rear end of the vehicle body, the loading platform, the lateral tilt, and the lateral tilt, and when the vehicle is loaded on the loading platform from the rear side. It also includes a detecting means for detecting that the vehicle is close to the lateral tilt and a notifying means for notifying that the vehicle is detected being close to the lateral tilt. With such a configuration, even a vehicle that is self-propelled and loaded on the loading platform can be prevented from shifting outward and coming into contact with the lateral tilt.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the first embodiment, an example in which the proximity sensor is installed backward will be described, and in the second embodiment, an example in which the proximity sensor is installed inward will be described.

(overall structure)
First, the overall configuration of the vehicle carrier 1 according to the embodiment of the present invention will be described with reference to FIGS. 1 (a) to 1 (c). As shown in FIG. 1, the vehicle carrier 1 of the present embodiment has a vehicle body 10 having a traveling function, a cabin 11 arranged in front of the vehicle body 10, and left and right extending in the front-rear direction of the vehicle body 10 behind the cabin 11. It includes a pair of swinging frames 12 and 12 and a loading platform 20 that is slidably attached along the swinging frames 12 and 12.

The slide mechanism of the loading platform 20 will be briefly described. Although not shown, the rear ends of the swing frames 12 and 12 are swingably attached to the rear ends of the vehicle body 10 via a swing shaft. Further, the front ends of the swing frames 12 and 12 are connected to each other, and one end (rod side) of the telescopic cylinder is connected to this portion. A roller member that moves along the swing frames 12 and 12 is attached to the other end (tube side) of the telescopic cylinder.

Further, a moving body having two upper and lower rollers is attached in the middle of the telescopic cylinder. Of these, the upper roller rolls along the swing frames 12 and 12, and the lower roller rolls along the subframe provided on the vehicle body 10. Therefore, when the telescopic cylinder expands and contracts, when the moving body moves, the swing frames 12 and 12 are tilted so as to be pushed upward by the moving body.

The loading platform 20 is attached to the telescopic cylinder via a double-speed moving mechanism, and moves by twice the amount of expansion and contraction of the telescopic cylinder. In this way, the loading platform 20 slides and moves along the swing frame 12 while tilting backward by expanding and contracting the telescopic cylinder.

As shown in FIG. 1 (b), on the front side of the loading platform 20, a winch for loading or unloading a vehicle (loaded vehicle) that cannot run on its own due to a failure or the like on the loading platform 20 or from the loading platform 20. 13 is installed. Then, during the loading work of the vehicle, the vehicle is stopped near the front end of the vehicle and the vehicle is pulled forward.

On the other hand, as shown in FIGS. 1 (a) and 1 (c), at the rear end of the loading platform 20, a road plate 30 for loading and unloading a vehicle (loaded vehicle) on the loading platform 20 and unloading from the loading platform 20 is rotated. It is installed so that it can move. That is, the road plate 30 is in a retracted state in which the road plate 30 is bent at a substantially right angle to the loading platform 20 during transportation (loading) of the vehicle (see FIG. 1A), and the loading platform 20 is extended during the loading operation of the vehicle. It is set to a deployed state where the tip is in contact with the road surface (see FIG. 2). In the deployed state shown in FIG. 2, the front end portion of the loading platform 20 is supported by the support legs 14.

(Composition of loading platform)
Next, the configuration of the loading platform 20 will be described. As shown in FIGS. 1A to 1C, the loading platform 20 includes a quadrangular flat floor 21 for loading a vehicle, a gate-shaped tory 22 erected on the front end side of the floor 21, and a gate-shaped tory 22. It is provided with horizontal tilts 23 and 23 that are erected on the left and right edge edges of the floor 21 so as to be openable and closable. Further, the winch 13 described above is arranged on the front side of the floor 21. Further, as described above, the road plate 30 is rotatably installed at the rear end of the floor 21. In addition, although not shown, a lashing device and the like are also arranged on the floor 21.

The lateral tilt 23 is formed in a rectangular cuboid shape (wall shape) having a short width and a long length, and is attached to the left and right edge edges of a quadrangular flat floor 21 via hinges. Therefore, the lateral tilt 23 can be opened to the outside as needed. Then, at the rear end portion 23a (see FIG. 3) of the lateral tilt 23 of the present embodiment, a proximity sensor 40 (see FIG. 3) is provided as a detection means for detecting that the vehicle is approaching the lateral tilt 23. is set up.

More specifically, as shown in FIG. 3, a substantially quadrangular notch region 24 having an open rear side and an inward side is formed in the rear end portion 23a of the lateral tilt 23. The proximity sensor 40 is installed rearward at a position toward the inward side of the side surface 25 facing rearward among the side surfaces 25 and 26 that partition the notch region 24. That is, the proximity sensor 40 is arranged at a position closer to the inside of the notch region 24 so that even a vehicle entering the notch region 24 can be reliably detected. The height at which the proximity sensor 40 is arranged is preferably set to a height at which the outermost bumpers and tires of the vehicle (vehicle to be loaded) can be easily detected.

The proximity sensor 40 is a non-contact type sensor that can non-contactly detect that a detection object including a vehicle has approached. The detection method of the proximity sensor 40 is either a high-frequency oscillation type using electromagnetic induction, a magnetic type using a magnet, or a capacitance type that detects a change in capacitance between the detected object and the sensor. May be good. The detection distance (detection range) of the proximity sensor 40 preferably stays inside the notch region 24, and is preferably substantially the same as the length of the notch region 24 (in this case, the length in the front-rear direction). .. As will be described later, the proximity sensor 40 is connected to the relay box 41 (see FIG. 4), and outputs / transmits the detection of the vehicle to the relay box 41.

(Control system configuration)
Next, the configuration of the control system S including the proximity sensor 40 of the vehicle carrier 1 of this embodiment will be described. As shown in FIG. 4, the control system S includes a proximity sensor 40, a relay box 41, and a notification means 43 such as a lamp or a buzzer. The relay box 41 has a built-in detection relay 42, and when it receives a signal from the proximity sensor 40, it is automatically laterally operated by a notification means 43 such as a lamp (for example, placed above the tory 22) or a buzzer. The rear end portion 23a of the tilt 23 is notified that the vehicle is in close proximity. The notification means 43 may be in any form as long as it can be notified, and may be, for example, a voice such as "The vehicle is approaching the lateral tilt."

(Action)
Next, the notification action of the vehicle carrier 1 of this embodiment will be described with reference to FIG. As shown in FIG. 5, the vehicle C advances on the road plate 30 in a state shifted to the leftward position in FIG. 5, advances on the loading platform 20, and is provided at the rear end portion 23a of the lateral tilt 23. Enter the notch area 24. Then, the proximity sensor 40 detects that the vehicle C is approaching.

For example, in the case of the high-frequency oscillation type proximity sensor 40, when the vehicle C approaches, an induced current flows in the proximity metal body due to the electromagnetic induction action, and the oscillation circuit constant changes due to a change in the inductance or loss of the detection coil. , Oscillation amplitude and oscillation frequency change. The proximity sensor 40 that has detected that the vehicle C is approaching outputs a signal to the relay box 41.

The relay box 41 that has received the signal automatically energizes the lamp or buzzer as the notification means 43 by the action of the detection relay 42. That is, the notification means 43 such as a lamp or a buzzer notifies that the vehicle C is approaching the lateral tilt 23. For example, the lamp arranged on the tory 22 blinks and the buzzer arranged on the tory 22 sounds.

Then, the driver of the vehicle C notified by the notification means 43 such as a lamp or a buzzer notices that the vehicle C is approaching the lateral tilt 23 and stops the vehicle C. After that, the driver of the vehicle C retracts the road plate 30 to correct the left and right positions, and then loads the vehicle C on the loading platform 20 again through the road plate 30.

(effect)
Next, the effects of the vehicle carrier 1 of this embodiment will be listed and described.

(1) As described above, the vehicle carrier 1 of the present embodiment is a proximity sensor as a detection means installed on the vehicle body 10, the loading platform 20, the lateral tilt 23, and the rear end portion 23a of the lateral tilt 23. 40, when the vehicle C is loaded on the loading platform 20 from the rear side, the proximity sensor 40 that detects that the vehicle C is close to the lateral tilt 23 and the vehicle C are close to the lateral tilt 23. It is provided with a notification means 43 for notifying that it has been detected. With such a configuration, even a vehicle C that is self-propelled and loaded on the loading platform 20 can be prevented from being displaced outward when being loaded and coming into contact with the lateral tilt 23. Therefore, safe, smooth, and quick loading work can be realized.

That is, when the vehicle C approaches the loading platform 20 and enters the notch region 24 in a state of being displaced outward, it is detected by the proximity sensor 40 and notified to the driver by the notification means 43 such as a lamp or a buzzer. Then, the notified driver can load the vehicle C after adjusting the position again by knowing that the vehicle C is approaching the lateral tilt 23.

(2) Further, notch areas 24, 24 with open rear and inward sides are formed in the lateral tilts 23, 23, 23a, 23a arranged on the left and right sides of the loading platform 20, and the proximity sensor is provided. 40 and 40 are configured to detect the vehicle C invading the notch areas 24 and 24. According to such a configuration, the vehicle C can be detected before coming into contact with the lateral tilt 23, and the vehicle C at the correct position that does not come into contact with the lateral tilt 23 is not erroneously detected.

(3) Further, since the proximity sensor 40 as the detection means is installed on the side surface 25 facing the rear that partitions the notch area 24 and is configured to detect the vehicle C, it is rearward to the proximity sensor 40. Vehicle C approaching from can be detected. In addition, since the proximity sensor 40 is arranged facing the notch area 24, an object (including the loaded vehicle C) comes into contact with the proximity sensor 40 during work, and the proximity sensor 40 is damaged. Can be prevented.

As shown in FIG. 6, the proximity sensor 40 of the present embodiment is located inside the side surfaces 25 and 26 that partition the notch region 24, at a position closer to the rear of the side surface 26 facing inward. It is installed toward you. That is, the proximity sensor 40 is arranged at a position closer to the rear of the notch region 24 so that the vehicle C entering from the rear of the notch region 24 can be quickly detected. The height at which the proximity sensor 40 is arranged is preferably set to a height at which the outermost bumper of the vehicle C can be easily detected.

The proximity sensor 40 is a non-contact type sensor that can non-contactly detect that a detection object including the vehicle C has approached. The detection method of the proximity sensor 40 may be any of a high frequency oscillation type, a magnetic type and a capacitance type. The detection distance (detection range) of the proximity sensor 40 preferably stays inside the notch region 24, and is preferably substantially the same as the width of the notch region 24 (in this case, the width in the left-right direction). As will be described later, the proximity sensor 40 is connected to the relay box 41, and outputs / transmits the detection of the vehicle C to the relay box 41.

Next, the action / effect of the proximity sensor 40 of this embodiment will be described. Since the proximity sensor 40 as the detection means is installed on the side surface 26 facing inward that divides the notch area 24 and is configured to detect the vehicle C, the detection range of the proximity sensor 40 is set from the rear. The crossing vehicle C can be detected. In addition, since the proximity sensor 40 is arranged facing the notch area 24, an object (including the loaded vehicle C) comes into contact with the proximity sensor 40 during work, and the proximity sensor 40 is damaged. Can be prevented.

Since the other configurations and the effects are substantially the same as those of the above-described embodiment, the description thereof will be omitted.
