Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temporary road connecting plate and a temporary road for facilitating passage of a wheeled vehicle having a heavy vehicle weight on a soft ground.

[0002]

2. Description of the Related Art Conventionally, a wheeled vehicle having a body weight of 20t to 30t, for example, a wheeled vehicle equipped with a missile launcher, sometimes slips and becomes incapable of traveling when running on a soft ground. There is. In such a case, an emergency road laying vehicle as shown in FIG. 12 was used. In this laying vehicle, a winding device 32 in which a continuous mat 30 made of reinforced plastic, aluminum or the like to be laid on the ground is wound around a roll shaft 31 is arranged on the loading platform, and the mat is laid on soft ground. In this case, when the laying vehicle retreats, the mat is sequentially laid under the tire of the vehicle. On the contrary, the mat laid on the ground is wound around the roll shaft of the winding device when the laying vehicle moves forward. The wheeled vehicle was allowed to run on the mat thus laid.

[0003]

However, according to the method of laying a temporary road consisting of such a continuous strip-shaped mat, the mat cannot be laid in a straight line depending on the topography of the soft ground to be laid. , When a curve was required for a part, the turning was difficult and the operability was poor. In addition, if the soft ground has long and short, there is a restriction on the length of the mat wound on the roll shaft, so if you try to make the applicable range as large as possible, you will need a large-scale winding device. Expenses tended to be expensive. In addition, depending on the surface condition of the soft ground, when the wheeled vehicle runs on this strip-shaped continuous mat, there is a phenomenon that the mat wavy, and once this wavy phenomenon occurs, this wavy phenomenon partially From the point where the mat floats, the length of the laying becomes shorter by this amount of lift, which causes the soft ground that was evenly covered on the ground to be partially exposed, and the wheeled vehicles that follow can run. lost. For this reason, there is a drawback that it takes a considerable amount of time to extend the raised portion and correct it. Therefore, the present invention is intended to solve the above-mentioned drawbacks, and the purpose thereof is to prevent the worker from being affected by the topographical condition of the soft ground regardless of the length, the presence or absence of a curve, the surface condition, etc. The purpose of the present invention is to provide a temporary road on which a wheeled vehicle can be reliably driven by relatively simple manual work.

[0004]

In order to solve the above-mentioned problems, the present invention adopts the following means. That is,
A plurality of rectangular parallelepiped aluminum light alloy plates, each of which has a protrusion on one end of the side surface and a depression on the other end and an uneven portion on the surface thereof, are sequentially attached to one plate. The protrusion of another plate is engaged with the recess.
In this way, the weight of the connecting plate formed by connecting multiple sheets is
It was configured to be approximately 10 to 50 kg. The total length of the connecting plates connecting the plates is longer than the diameter of the tire of the wheeled vehicle, but shorter than the axial distance between the front and rear of the double tire of the wheel of the wheeled vehicle. On the other hand, the length in the major axis direction of the rectangular parallelepiped plate is longer than the width of the double tire of the rear wheel of the wheeled vehicle, but is shorter than half the axial distance between the left and right wheels of the wheeled vehicle. did. or,
The connecting plates were arranged in two rows in the traveling direction of the wheeled vehicle, and the adjacent connecting plates in the traveling direction were connected by joint wires. On the other hand, the connecting plates facing each other at right angles to the traveling direction are connected by a rigid rod or a flexible joint wire. Further, a fan-shaped connecting plate is provided between the connecting plates in the shape of a rectangular parallelepiped in the middle of the above-mentioned temporary road, or at the front end or the rear end of the temporary road depending on the terrain, and it is arranged on a straight line. The path of the wheeled vehicle is configured to be changeable by the fan-shaped connecting plate.

[0005]

[Operation] When laying a temporary road, the worker, in the traveling direction of the wheeled vehicle, lays out the connecting plates in order on the soft ground, and then connects the connecting wires between the connecting plates with one touch. Engage with the hook to connect. On the other hand, in the direction perpendicular to the traveling direction of the wheeled vehicle, engage the carabiner haken attached to both ends of the distance rod with the eye bolts fixed to the side surface of the connecting plate, or connect the eye bolts to both ends of the joint wire. Prepare and place it by penetrating the horn part of the, and connect it by fastening with bolts when laying. When the wheeled vehicle travels on the temporary road laid in this way, unevenness is provided at predetermined intervals on the surface of each plate that constitutes the connecting plate. The slip of the tire is prevented from the point where the tire contacts the two points. Also,
Since the connecting plate is divided for each unit, the wheeled vehicle is placed on this connecting plate for each tire, so that its own weight is dispersed and loaded, and it is not continuous like a strip. Therefore, the wavy phenomenon like a continuous mat is avoided. Furthermore, depending on the topographical conditions of the soft ground,
Since a fan-shaped connecting plate is placed on the temporary road where a curve is required, the route of the temporary road can be freely set by combining the linear connecting plate and this fan-shaped connecting plate. . Further, since the weight of the connecting plate is made of an aluminum alloy and is about 10 kg to 50 kg, it is possible for a worker of about 2 to 4 people to perform the laying work and the withdrawing work very easily.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A temporary road for carrying out the present invention will be specifically described with reference to the drawings. In FIG. 1, a plate 1 is made of aluminum light alloy and has a rectangular parallelepiped shape.
The protrusion 1a and the recessed portion 1b at the other end are provided with the concave and convex portions 1c for preventing the tire of the wheeled vehicle 20 from slipping at both ends of the surface in the minor axis direction. I have it. In addition, a space 1d is formed on the cross section of the plate 1.
Is provided as a honeycomb structure to reduce the weight of the entire structure and to increase the mechanical strength. Further, the plate 1 has a symmetrical shape with respect to the center line in the thickness direction so that the plate 1 can be used without distinction between the front and back.

In FIG. 2, the connecting plate 2 is the above-mentioned 1
The recessed portion 1b of the individual plate 1 is engaged with the protruding portion 1a of another plate 1 and a plurality of (9 in the figure are illustrated) are connected to each other. The connecting length A of the connecting plate 2 is longer than the diameter d of the tire 20a of the wheeled vehicle 20 as shown in FIGS. Distance LA
It is formed shorter. On the other hand, the width B of the connecting plate 2 (this width is the same as the major axis direction of the plate 1) is the width w of the double tire 20a of the rear wheel of the wheeled vehicle 20.
Longer, but the axial distance L between the left and right wheels of this wheeled vehicle 20
It is formed to be shorter than half of B. As described above, the length A and the width B of the connecting plate 2 are limited because, when the wheeled vehicle 20 is mounted on the connecting plate 2, the weight of the wheeled vehicle 20 is dispersed for each tire. Is to take charge. Further, the connection plate 2 is divided for each unit and is not made continuous in a band shape because it eliminates the waving phenomenon in which a part of the mat floats up and makes it easy for an operator to handle. Moreover, it is for facilitating the laying. Further, if the length A and the width B of the connecting plate 2 are out of the ranges described above, it is difficult for the worker to easily handle them by hand, and if the laying work uses a large mechanical device. This is because it is unavoidable and not preferable. Moreover, the weight of one connecting plate 2 is approximately 10K.
A range of about g to 50 kg is preferable. The reason is that it is convenient for about 2 to 4 workers to lay, withdraw, or transport, and if it is outside this range, for example, if it is 10 kg or less, work is done. This is because it is not convenient for a wheeled vehicle of 20t to 30t class in terms of strength, and on the other hand, when it exceeds 50 kg, workability is poor and it is not preferable.

In FIGS. 3, 4 and 5, there are two sets of the connecting plates 2 and the joint wires 3 are connected between them. That is, the pin 4 is attached to one end of the connecting plate 2, and the joint wire 3 is attached to the pin 4. On the other hand, as shown in FIG. 5, a one-touch hook 5 is attached to the other end of the connecting plate 2. That is, the one-touch hook 5 has a bent front end, a flange 5a provided at the center, and a male screw at the lower end, which is fitted into a hole 1e formed in the protrusion 1a of the plate 1. A nut 5b is screwed and attached to the threaded portion through a coil spring 6, and when the tip of the one-touch hook 5 is pulled upward, the bent tip of the one-touch hook 5 and the plate 1
A gap is formed between the gap and the gap, and the ring portion 3a of the joint wire 3 can be fitted into the gap. The length of the joint wire 3 is preferably about 4 cm to 8 cm. The reason is that if it is too long,
When the wheeled vehicle 20 is placed on the connecting plate 2, the tire of the wheeled vehicle 20 comes into contact with the surface of the soft ground,
Therefore, the tire presses the end portion of the connecting plate 2 and a part of the connecting plate 2 floats up, which may cause a so-called waviness phenomenon. A fastener such as an eyebolt 8 shown in FIG. 9 may be used instead of the one-touch hook 5 described above. In this case, the knuckle portion 3a of the joint wire 3 is previously attached to the knuckle portion of the eyebolt 8. You may make it penetrate and it may be tightened and connected by the nut 5b at the time of installation.

Depending on the terrain condition of the soft ground to be laid, the connecting plate 2 cannot be arranged in a straight line, and when a curved portion is absolutely necessary, instead of the above-mentioned rectangular parallelepiped connecting plate 2, FIG. A fan-shaped connecting plate 7 is used as shown in FIG. This fan-shaped connecting plate 7 shows an example in which the central angle is approximately 30 degrees, but it goes without saying that it is not limited to this.
The joint wire 3 is also attached to the side surface of the fan-shaped plate 7. Note that FIG. 11 shows an example in which the fan-shaped connecting plate 7 is divided into three, and the central angle of one connecting plate is 10 degrees. The reason for dividing in this way is that the center angle can be selected by appropriately selecting the number of the fan-shaped plates 7. Further, the width of the fan-shaped connecting plate 7 is formed to be larger than the width of the rectangular parallelepiped connecting plate 2 so that the wheeled vehicle 20 can smoothly travel on a curved portion. This is to prevent wheel removal due to the difference in the radius of gyration between the front wheels and the rear wheels of the wheeled vehicle 20 at this curved portion. The place where the fan-shaped plate is laid may be the tip or the tail of the temporary road depending on the terrain.

Usually, the depression portion 1 of one plate 1 is previously prepared.
The protrusion 1a of another plate 1 is engaged with b to prepare and place it as a connecting plate 2 having a predetermined length and width,
The connection plates 2 are stacked and stored. That is,
The connection plate 2 shown in FIG. 3 is bent at the joint wire 3 part and stacked on the connection plate 2 shown in FIG. Since the plate 1 is formed symmetrically on the front and back sides, the uneven portions on the surface fit into each other, and even if the connecting plates 2 are stacked, they do not shift laterally. In this way, the stored connection plate 2 is transported by a truck or the like to the destination where the user wants to lay it.
Now, when arriving at a soft ground and laying a temporary road and running a wheeled vehicle, the worker first sequentially connects the connecting plate 2 in the traveling direction of the wheeled vehicle 20 as shown in FIG. Two
Assemble them in a row and lay them in the required number continuously. This laying work does not require a special device, and is easily performed manually by a worker. That is, with respect to the traveling direction of the wheeled vehicle 20, the connecting plate 2 can be connected very simply and sequentially by only engaging the one-touch hook 5 with the ring portion 3a at one end of the joint wire 3. When an eyebolt is passed through the tip of the joint wire 3, a nut is screwed into the threaded portion provided on the lower portion of the eyebolt 8 for fastening.

On the other hand, at this time, as shown in FIG. 9, eye bolts 8 are attached to appropriate portions of the connecting plate 2 in the direction perpendicular to the traveling direction of the wheeled vehicle 20 (vertical direction in FIG. 7). Therefore, the separately-stored rigid distance rod 9 shown in FIG. 8 connects the connecting plates 2 and 2 facing each other. That is, the distance rod 9 is formed with a tan buckle mechanism 12 at the center thereof so that its length can be adjusted, and a carabiner haken 10 is attached to both ends of the distance rod 9. Is engaged with the eyebolt 8 fixed to the side surface of the connecting plate 2. Carabiner Haken 10 has screws 11
It is attached to the distance rod 9 by 360 degrees so as to be rotatable. Since the surface of the soft ground is uneven, the connecting plate 2 is formed so as to be rotatable 360 degrees.
Connection plates 2 facing each other when installed
This is to prevent it from being twisted even if the position is shifted vertically. In this way, since the traveling direction of the wheeled vehicle 20 and the direction at right angles are sequentially connected, the connecting plate 2 can be kept parallel even when the wheeled vehicle 20 travels. In some cases, the flexible joint wire 3 may be used instead of the rigid distance rod 9 described above. That is, in the case of the flexible joint wire 3, it is a matter of course that the two connecting plates 2 and 2 are prevented from separating to the outside, but depending on the terrain, the connecting plates 2 and 2 facing each other may be separated. This is because the wheeled vehicle does not have to derail from the connecting plate even if it approaches the center. In this case, it is empirically known that the joint wire 3 is embedded in the soft ground between the facing connecting plates 2 and 2. On the other hand, in the case of a rigid rod, the carabiner Haken 10 attached to the distance rod 9 may be damaged. Therefore, the joint wire or the distance rod may be appropriately selected depending on the condition of the terrain to be laid.

FIG. 11 shows an example in which a temporary road according to the present invention is laid on a soft ground. The connecting plates 2 are arranged in two rows with respect to the traveling direction of the wheeled vehicle 20. However, the wheeled vehicle 20 travels on this temporary road. As shown in FIG. 1, a concavo-convex portion 1c is provided on the surface of each plate 1 constituting the connecting plate 2, and the tire 20a of the wheeled vehicle 20 should contact between two points of the concavo-convex portion 1c. This surely prevents the slip. In addition, since the individual plate 1 is in a state of engaging with the projection 1a of the recess 1b of the other plate 1, the elasticity generated from the engaging portion of the individual plate 1 This helps prevent the vehicle from slipping and prevent the connecting plate 2 from rising. At this time, the tire 20a of the wheeled vehicle 20 is always placed on the one connecting plate 2, and the weight of the wheeled vehicle 20 is dispersed and loaded on the independent connecting plates 2. The ground pressure between the soft ground and the connecting plate 2 is reduced, and the sinking of the connecting plate 2 due to the weight of the wheeled vehicle 20 can be prevented.
Further, even if a curved portion is required for the temporary road due to the topographical condition of the soft ground, the fan-shaped connecting plate 7 is used instead of the rectangular parallelepiped connecting plate 2 in this curved portion.
Since the wheeled vehicle 20 slips,
You can travel smoothly and reach your destination without taking off the wheels. On the other hand, the removal of this temporary road can be done in the reverse order of the laid work, and also by a simple manual work of the worker.

[0013]

In the temporary road of the present invention, a plurality of aluminum light alloy plates having a predetermined width and length as described above are connected to form one connection plate unit. The appropriate number of joint wires are sequentially connected to the running direction of the wheeled vehicle, and the distance rods between the units facing each other in the direction perpendicular to the running direction of the wheeled vehicle are connected. Or, since it is configured to be connected by a joint wire or the like, compared with a conventional one laying a belt-shaped continuous mat, tires of wheeled vehicles are individually mounted on independent connecting plates, It is possible to prevent the mat from waving and slipping because the weight of the wheeled vehicle is dispersed, and the connecting plate is connected with a joint wire or the like. Prevent the subsidence of the connecting plate alone. In addition, since the weight of one connecting plate is about 10 kg to 50 kg, it can be done by a simple manual work of several workers, so that large-scale auxiliary equipment such as a take-up device for winding up the mat is completely eliminated. It is not necessary, and depending on the terrain situation, the number of connecting plate units can be increased or decreased depending on the length of the top and bottom.On the other hand, if there is a curve, a fan-shaped plate is used for connecting plate units. Since it can be accommodated between them, the traveling direction of the wheeled vehicle can be freely selected.
