Regulated.

Next, a lashing method using the wheel lashing device described above will be explained. Note that the lashing procedure described below is not intended to be limited, and can be changed back or forth as appropriate.

First, the loaded vehicle 10 is loaded onto the platform 2 of the loaded vehicle 1. At this time, the lashing jigs 20L and 20R are moved to the left and right sides of the loading platform 2 so that the loaded vehicle 10 does not run onto the lashing jigs 20L and 20R. After boarding the loaded vehicle 10, move the lashing jig 20L to an appropriate position outside the front wheels 11L of the loaded vehicle 10, and abut the front end 42L of the rail member 41L against the lower part of the torii gate 3 via the seat member 43. . Note that the wire rope 51L, one end of which is connected to the connecting ring 29L, is sequentially inserted through the wire guide 35L, the wire guide 28L, and the wire guide 27L.

Next, the sleeve 22L is slid on the rail member 41, the front unit 21L is rotated around the rail member 41, the regulation arm 23L is passed through the space 14L on the front side of the tire house of the loaded vehicle 10, and the front wheel 11L is brought into contact with the front tread 12L. In this state, the stopper pin 45L is inserted into the rearmost pin hole 46L ("right" in FIG. 3) among the exposed pin holes 46L. This restricts forward movement of the sleeve 22L and, in turn, the front unit 21L with respect to the rail member 41L.

Next, the sleeve 32L is slid on the rail member 41, the rear unit 31L is rotated around the rail member 41, the regulation arm 33L is passed through the space 15L on the rear side of the tire house of the loaded vehicle 10, and the rear unit 31L is rotated around the rail member 41. It is brought into contact with the tread 12L of the wheel 11L. In this state, the stopper pin 47L is inserted into the pin hole 48L located furthest forward ("left" in FIG. 3) among the exposed pin holes 48L. This restricts rearward movement of the sleeve 32L and, in turn, the rear unit 31L with respect to the rail member 41L.

Next, the wire rope 51L between the wire guide 35L and the wire guide 28L of the lashing jig 20L is wrapped around the outer periphery of the front wheel 11L in an arc shape. At this time, as shown in FIG. 4, the wire rope 51L extending from the wire guide 35L is passed under the regulation arm 33L and folded back upward, and then wound further forward around the front wheel 11L. Further, as shown in FIG. 5, the wire rope 51L is positioned such that the wire rope 51L extending from the rear end of the regulating arm 33L toward the wire guide 28L contacts the center of the tread width of the tread 12L of the front wheel 11L.

Further, tension is applied to the wire ropes 51L, 51R extending forward via the wire guides 28L, 28R and the wire guides 27L, 27R. As a result, the restriction arms 23L, 23R and the restriction arms 33L, 33R are firmly pressed against the front wheels 11L, 11R of the loaded vehicle 10, and the wire ropes 51L, 51R wrapped around the outer circumferences of the front wheels 11L, 11R Treads 12L, 12R of wheels 11L, 11R are firmly secured to securing jigs 20L, 20R.

In conventional lashing devices, each wheel of the loaded vehicle is firmly secured with a lashing belt to prevent the wheels of the loaded vehicle from climbing over the wheel chocks due to inertia when the vehicle is suddenly braked. The lashing work required time and effort.

In contrast, in the present embodiment, the front wheels 11L, 11R of the loaded vehicle 10 are wrapped between the front units 21L, 21R that restrict the forward movement and the rear units 31L, 31R that restrict the backward movement. The front wheels 11L, 11R are secured to the securing jigs 20L, 20R by pulling the wire ropes 51L, 51R forward by the electric winch 4 mounted on the vehicle loaded vehicle 1.

According to the present embodiment, since the lashing force is generated auxiliary by the power of the electric winch 4, there is no need for the complicated work of tightening a lashing belt to each wheel as in conventional lashing devices, so the lashing The effort and time required for work can be reduced.
In addition, in this embodiment, damage to the loaded vehicle 10 due to excessive winding force of the electric winch 4 is prevented by selecting the wire ropes 51L, 51R or the wire rope 52 to be used based on the breaking load. be able to.
Further, as described above, the electric winch 4 is for assisting the lashing force, and for example, it is also possible to configure the lashing force to be generated by a load tightening device.
Further, in this embodiment, the regulating arms 23L, 23R of the front units 21L, 21R are brought into contact with positions near the height of the axles of the treads 12L, 12R at the front of the front wheels 11L, 11R, and the The front ends 42L, 42R of the rail members 41L, 41R of the binding jigs 20L, 20R are made to abut against the torii gate 3 (front side wall) of the vehicle-loaded vehicle 1, so that, for example, when the vehicle-loaded vehicle 1 is suddenly braked. Even if the loaded vehicle 10 moves forward with respect to the loading platform 2, it can be reliably prevented from moving forward. Furthermore, it is possible to absorb the inertial force of the loaded vehicle 10 when the loaded vehicle 1 is suddenly braked by the air pressure of the tires (numerals omitted) around which the wire ropes 51L and 51R are wound.
Moreover, in this embodiment, since the lashing jigs 20L, 20R and the wire ropes 51L, 51R are brought into contact with only the treads 12L, 12R of the front wheels 11L, 11R, Will not damage the wheels (code omitted).
