To the next, the operation of the profile elongated object carrying equipment according to the present invention, based on the description of the operation, a method for transporting a different shape long product.
[0030]
6 to 7 show work procedures for loading, transporting, and unloading the deformed long object B from the transport source to the transport destination.
[0031]
First, the deformed long object B is loaded on the support base 2 mounted on the loading platform 12 of the vehicle 1 at the transportation source.
At this time, the deformed long object B is suspended from the upper side or is suspended from the side and loaded on the tilted support base 2.
In this loading operation, in order to stabilize the vehicle 1, the lateral arm 61 and the longitudinal arm 62 of the auxiliary wheel mechanism 6 can be extended and the auxiliary wheel 63 can be grounded.
Moreover, when there is a restriction | limiting in the stacking direction of the unusually long elongate B in a conveyance origin, the turning mechanism 5 can be driven and the horizontal direction of the support stand 2 can also be adjusted.
[0032]
In a state in which the deformed long object B is loaded on the support table 2 (the length direction of the support table 2 is directed in the front-rear direction of the vehicle 1), the lower support frame 21 of the support table 2 is the turning mechanism 5. Since the weight 41 of the center-of-gravity adjusting mechanism 4 is positioned on the front side on the swivel base 53 of the turning mechanism 5, the deformed long object B is supported by the support base 2 (the loading platform 12 of the vehicle 1). Even if it protrudes with a long protrusion length a, stable overhang type loading is completed.
[0033]
After the deformed long object B is loaded on the support base 2, the vehicle 1 travels toward the transportation destination.
[0034]
When the traveling vehicle 1 reaches a corner (including a winding road), it is determined whether or not the vehicle 1 can pass from the turning radius c.
If it is determined that the vehicle cannot pass, the vehicle 1 is stopped and the hydraulic cylinder 32 of the hoisting mechanism 3 is driven to erect the support base 2.

[0036]
After passing the corner, the vehicle 1 is stopped again.
And by the reverse operation of the hoisting mechanism 3, the center-of-gravity adjustment mechanism 4, the turning mechanism 5, and the auxiliary wheel mechanism 6, the deformed elongated object B is returned to the posture before passing through the corner.
In order to maintain the stability of the vehicle 1 can be stored in a both side portions of the bed 12 of the vehicle 1 by the reverse of the operation of the auxiliary wheel mechanism 6 is preferably to finally performed.
[0037]
When the vehicle 1 arrives at the transportation destination, the vehicle 1 is stopped and the unloading operation reverse to the loading operation at the transportation source is performed.
At this time, as shown in FIG. 7, the horizontal arm 61 and the vertical arm 62 of the auxiliary wheel mechanism 6 are extended to ground the auxiliary wheel 63, and the support base 2 is raised by the hoisting mechanism 3 and left and right by the turning mechanism 5. The unloading work by lifting can be facilitated by turning and adjusting the direction by raising the irregular long object B.
Further, as shown in FIG. 8, the horizontal arm 61 and the vertical arm 62 of the auxiliary wheel mechanism 6 are extended to ground the auxiliary wheel 63, the support base 2 is turned left and right by the turning mechanism 5, and the deformed long object B is By adjusting the direction without standing up, it is possible to avoid surrounding obstacles and facilitate unloading work by lateral movement.
[0038]
As described above, in addition to the illustrated embodiment, the deformed long object B can be a target other than a blade of a wind turbine for wind power generation.
[0039]
Furthermore, the undulation mechanism 3 and the center-of-gravity adjustment mechanism 4 may be driven by a motor, a gear, a chain or the like instead of the hydraulic cylinders 32 and 42.
[0040]
Further, instead of the center-of-gravity adjustment mechanism 4, it is possible to make the entire center of the vehicle 1 stand up and move in the front-rear direction to make the center of gravity appropriate.
[0041]
