Description

[Technical Field]

[0001] FIELD An embodiment of the present invention relates to a vehicle immobilization device and a vehicle immobilization method. [Background technology]

[0002] 2. Description of the Related Art There is a general public demand for vehicles to be firmly secured to the ground or the like, and for example, wheel chocks, outriggers, and the like are widely used as vehicle securing devices and methods.

[0003] Wheel chocks are installed to prevent a vehicle from moving forward or backward. For example, when parking a vehicle on a slope, they are a simple device and method that can be installed to prevent the vehicle from rolling down the slope under its own weight if the parking brake is released. This method does not require any modifications to the vehicle itself, but it does reduce the ability to secure the vehicle to the ground.

[0004] Outriggers are used on cranes and aerial work platforms to extend the boom or lift objects, and are attached to the vehicle body to secure it to the ground. While the system is relatively simple, it requires the outrigger system to be attached to the vehicle itself. Furthermore, while they are highly effective at securing the vehicle to the ground, in many cases only the tip of the outrigger system is touching the ground, which reduces the effectiveness of securing the vehicle when the ground shakes violently, for example, during an earthquake.

[0005] Therefore, in addition to the applications for which the wheel chocks and outriggers are intended, there is a need for a system that can firmly secure vehicles even in the event of natural disasters such as earthquakes and strong winds.

[0006] For example, Patent Document 1 discloses a method of fixing a vehicle to the ground by firmly installing dedicated fixing jigs on both the ground and the vehicle and connecting the jigs together. While this method can firmly fix a vehicle to the ground in the event of a natural disaster such as an earthquake or strong wind, it has the drawback of requiring modifications to the vehicle in order to connect the vehicle to the ground with dedicated jigs.

[0007] Furthermore, for example, Patent Document 2 proposes a device and method for firmly securing a vehicle to the ground by securing only the vehicle tires, without requiring any modifications to the vehicle itself. This method involves placing the vehicle on a base plate, restraining the tire horizontally (front, back, left, and right) with retaining members, and vertically restraining the tire by using steel plates to press the tire down to the ground, which are then bolted to secure the vehicle. This method is considered superior in that it can firmly secure a vehicle to the ground in the event of natural disasters such as earthquakes or strong winds, and does not require any modifications to the vehicle. However, this method requires a complex structure, an associated increase in the number of parts, and the supply of specialized parts, which increases the difficulty of designing, manufacturing, and installing the device on-site.

[0008] Also, for example, Patent Document 3 proposes a method of fixing vehicle tires to the bed of a vehicle transporter with a belt-like belt. However, this method does not fix the vehicle to the ground, and its purpose is to prevent damage to the vehicle being transported due to vibrations from the vehicle transporter.

[0010] As mentioned above, there has long been a need for the development of a vehicle fixing device and method that does not require vehicle modification, has a simple structure, is easy to design, manufacture, and install on-site, and can firmly fix a vehicle to the ground even in the event of a natural disaster such as an earthquake or tornado.

[0011] The present invention has been made in response to such conventional circumstances, and aims to provide a vehicle fixing device and a vehicle fixing method that do not require vehicle modification, have a simple structure, are easy to design and manufacture, and install the device on-site, and can firmly fix a vehicle to the ground even in the event of a natural disaster such as an earthquake or tornado. [Means for solving the problem]

[0012] The vehicle fixing device of the embodiment is a vehicle fixing device that fixes a vehicle that is made capable of running by tires to the ground, and is characterized by comprising: a horizontal beam arranged along a direction perpendicular to the running direction so as to suppress movement of the tire in the running direction; a vertical beam arranged along the running direction so as to suppress movement of the tire in the direction perpendicular to the running direction; and a sling installed around the tire so as to suppress movement of the tire in the vertical direction.

[0013] The vehicle fixing method of the embodiment is a vehicle fixing method for fixing a vehicle that is made capable of running by tires to the ground, and is characterized in that the vehicle is fixed using horizontal beams arranged along a direction perpendicular to the running direction so as to suppress movement of the tires in the running direction, vertical beams arranged along the running direction so as to suppress movement of the tires in the direction perpendicular to the running direction, and a sling installed around the tires so as to suppress movement of the tires in the vertical direction. [Effects of the Invention]

[0014] According to the present invention, it is possible to provide a vehicle fixing device and a vehicle fixing method that do not require vehicle modification, have a simple structure, are easy to design and manufacture, and install the device on site, and can firmly fix a vehicle to the ground even in the event of a natural disaster such as an earthquake or tornado.

[0015] [Figure 1] 1 is a diagram schematically illustrating an overall configuration of a vehicle fixing device according to an embodiment; [Figure 2] 2 is a diagram showing a top view of the main part of the vehicle fixing device according to the embodiment shown in FIG. 1; FIG. [Figure 3] 2 is a side view showing the configuration of a main part of the vehicle fixing device according to the embodiment shown in FIG. 1; [Figure 4] 2 is a front view showing the configuration of a main part of the vehicle fixing device according to the embodiment shown in FIG. 1. FIG. DETAILED DESCRIPTION OF THE INVENTION

[0016] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A vehicle fixing device and a vehicle fixing method according to an embodiment will be described below with reference to the drawings.

[0017] Fig. 1 is a diagram schematically showing the overall configuration of a vehicle fixing device 100 according to an embodiment. The drivable vehicle shown in Fig. 1 is a truck 108 as a transportable vehicle, and examples of the load 107 mounted on this truck 108 include a gas turbine power generation system and a diesel power generation system. The truck 108 is equipped with a plurality of tires (wheels) 105 and is configured to be self-propelled.

[0018] Fuel pipes for supplying fuel used in power generation and power cables for the generated electricity will compete with pipes and cables installed outside the vehicle, but in the event of a natural disaster such as an earthquake or strong wind, the vehicle body (truck 108) may shake. Therefore, in order to absorb the shaking while still functioning as the load 107, expansion joints must be used to connect the pipes, and the cables must also be designed to prevent breakage due to the shaking.

[0019] FIG. 2 is a diagram showing the top view of the main parts of the vehicle fixing device 100, FIG. 3 is a diagram showing the side view of the main parts as viewed from a direction perpendicular to the traveling direction of the truck 108, and FIG. 4 is a diagram showing the front view of the main parts as viewed from the traveling direction of the truck 108.

[0020] As shown in these figures, the vehicle immobilization device 100 includes multiple cross beams 101 arranged in a direction perpendicular to the traveling direction so as to suppress movement of tires 105 in the traveling direction. These cross beams 101 are arranged to hold down the front and rear tires 105 from the front and rear, thereby suppressing movement of the truck 108 in the traveling direction. In addition, slings 104 are wrapped around the tires 105 and fixed to the cross beams 101 with bolts, thereby suppressing movement in the vertical direction. Note that the slings 104 may be belt-shaped slings made of high-strength wire. In this embodiment, the cross beams 101 are arranged on a flat base plate 106 made of a steel plate or the like.

[0021] The vehicle immobilization device 100 also includes fixed longitudinal beams 102a and movable longitudinal beams 102b, which are disposed on both sides of the track 108 along the running direction so as to suppress movement of the tire 105 in a direction perpendicular to the running direction. In this embodiment, the fixed longitudinal beam 102a is fixed on a base plate 106. The movable longitudinal beam 102b is supported by the fixed longitudinal beam 102a and is movable or shiftable in a direction approaching or moving away from the tire 105. This movement or shifting can be achieved by a screw mechanism such as a bolt and a nut.

[0022] The horizontal beam 101, the fixed vertical beam 102a, and the movable vertical beam 102b can be constructed using, for example, rectangular cylindrical beam members (steel materials) that are widely used in general industry.

[0023] As described above, when using the base plate 106, first, the fixed vertical beam 102a is fastened and fixed to the base plate 106 by bolts or welding. Then, by using the fixed fixed vertical beam 102a to adjust the positions of the cross beam 101 and the movable vertical beam 102b, it becomes possible to fix the tire 105 regardless of the parking position of the vehicle on the base plate 106. Furthermore, because the beams can be freely arranged on the steel plate of the base plate 106, it becomes possible to fix the vehicle taking into account constraints due to the size of the vehicle and the installation location of the device. In addition, the beams and other components to be used can be installed on the base plate 106 in advance to assemble most of the vehicle fixing device 100. At the installation site of the vehicle fixing device 100, all that needs to be done is to fix the base plate 106 to the ground, place the vehicle on the base plate 106, and assemble it to fix the tire 105, thereby enabling the device to be quickly installed and used.

[0024] Although the above describes the case where the base plate 106 is used, it is also possible to provide a pillar on the fixed vertical beam 102a without using the base plate 106 and directly fix the pillar to the ground using foundation bolts (or other methods such as Chemical Anchors (registered trademark), stakes, etc.). For example, if a vehicle is already parked in a fixed position and it is not desired to move the vehicle, it is not possible to install the base plate 106. Therefore, if such a method is used, it is possible to fix the vehicle to the ground without moving it, although this increases the amount of work required for on-site construction.

[0025] As described above, according to the vehicle fixing device and vehicle fixing method of this embodiment, the tire 105 can be firmly fixed to the ground and the position of the entire vehicle can be fixed by using general-purpose parts and simply processing and assembling them.

[0026] Additionally, beam members (steel materials) that are widely used in general industry are used to secure the tires 105 in the horizontal direction, and they are restrained in two horizontal directions. The length, cross-sectional performance, and installation position of the beams can be freely arranged as long as strength can be ensured. Additionally, slings 104 that are commonly used in general industry are used to secure the tires 105 in the vertical direction, and the size of the slings 104 can also be freely chosen as long as strength can be ensured. Furthermore, the vehicle securing device 100 can be flexibly installed depending on the number and size of the tires 105, and the size of the entire vehicle.

[0027] Furthermore, the strength-constituting members of the vehicle immobilization device 100 of this embodiment are steel beams, bolts (nuts), and a sling 104. The strength of the steel is determined by the material and cross-sectional properties such as size and plate thickness. The strength of the bolt is determined by the material and diameter. Furthermore, the strength of the sling 104 is determined mainly by the material of the internal wires and the bundled diameter. Therefore, each strength member that constitutes this device can be freely changed within the range in which it performs its respective function. Therefore, because the strength and arrangement of each strength member can be freely changed within the range in which it performs its function, the performance of the vehicle immobilization device 100 can be easily adjusted.

[0028] Although several embodiments of the present invention have been described above, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be embodied in various other forms, and various omissions, substitutions, modifications, and combinations can be made without departing from the spirit of the invention. These embodiments and their modifications are included within the scope and spirit of the invention, and are also included in the scope of the invention and its equivalents as defined in the claims.
