It was carrying heavy objects. (See JP-A-54-118027)

[0003]

SUMMARY OF THE INVENTION Using the conventional pole trailer carrier described above, the maximum diameter exceeds about 4 m,
In order to transport a tower consisting of a cylindrical structure for wind power generators having a length of about 21 m, a garter frame of a low and medium floor type for mounting the tower is required, and the maximum diameter exceeds about 4 m. Therefore, the highest position including the height of the garter frame exceeds 6 to 7 m. Therefore, when traveling in an urban area, there is a possibility that a road obstacle such as a pedestrian bridge cannot be made, so that a wasteful traveling such as having to choose a distant route and go through a detour or a reinforcement work of a bridge or a road surface may be required. .

Accordingly, an object of the present invention is to provide a crimping frame having a hydraulic silling on a tow truck and a neck rotatably mounted on a rear trailer, facing each other, and between load receiving claws disposed above and below the crimping frame. It is an object of the present invention to provide a means for directly engaging and supporting the front and rear ends of a long tower for a direct wind power generator to transport the tower in a low attitude.

[0005]

The object of the present invention is to provide a crimping frame having a hydraulic cylinder opposed to a tow car and a neck rotatably mounted on a rear trailer, and provided above and below both crimping frames. This is achieved by directly engaging and supporting the front and rear ends of a long tower having a cylindrical structure for a wind power generator between liftable receiving claws, and transporting the tower while adjusting the vertical movement in a low attitude.

The object of the present invention is to provide a tower transporting apparatus having a cylindrical structure for a wind power generator, wherein the crimping frame is formed in a rectangular structure having a length substantially equal to the maximum diameter of the cylindrical structure. This is achieved by connecting a hydraulic cylinder and pivotally supporting one lower side to a neck plate.

[0007] The object of the present invention is to provide a tower transporting apparatus having a cylindrical structure for a wind power generator according to claim 1 or 2, wherein a plurality of insertion holes for receiving claws are formed on both sides of a lower end of the crimping frame, and a center of the bottom of the crimping frame. The upper end of the cylinder provided in the part is connected to the center of the lifting plate that can be raised and lowered between both sides of the crimping frame,
This is achieved by providing a load receiving claw on the left and right of the upper end of the lifting plate.

[0008] The object is to provide a cylindrical carrier for a wind power generator according to any one of claims 1 to 3, wherein a large number of holes are provided on both sides of a crimping frame of a lifting range of a lifting plate. This is achieved by inserting a knock pin into a hole near the lower side of the lifting plate.

[0009] The object of the present invention is to provide a tower transport device having a cylindrical structure for a wind power generator according to any one of claims 1 to 4, wherein leaf springs are attached to both sides of all the receiving claws, and the leaf springs are engaged and supported. This is achieved by the fact that the rotation of the receiving claw is prevented by being pressed by the peripheral portion of the tower, thereby facilitating the fixing of the receiving claw.

[0020]

[Explanation of Transport of Tower] A case of transporting a tower 21 having a maximum diameter (about 4 m) and a length of about 20 m for a wind power generator to be transported by the apparatus of the present invention will be described. The hydraulic cylinder 11 is operated with the load receiving claw 18 above the vertical crimping frame 4 disposed on the rear trailer 30 fixed at the static position in the upward normal posture, and the elevating plate 12 is slightly lowered. At the same time, the lower receiving catch 26 is inserted into the lowermost insertion hole 25 in a downward state.

In this position, the rear trainer 30-2
The towing vehicle 1 is arranged on the same front axis at a distance of 0 m or more, and the crimping frame 4 and the upper and lower receiving claws 18 and 26 provided on the towing vehicle 1 are also set in the same manner as described above.

In this state, one end of the tower 21 held horizontally between the towing vehicle 1 and the crimping frames 4 and 4 of the rear trainer 30 is brought into contact with the crimping frame 4 of the rear trainer 30 and the tower 21 Receiving the flange 23 with the claws 26
The movement of the tower 21 is stopped at a position below the partition plate 17 of FIG.

Then, the towing vehicle 1 is gently retreated, and the retraction of the towing vehicle 1 is stopped after the flange 23 of the tower 21 is positioned below the lower loading catch 26 provided on the crimping frame 4. At this time, the tower 21 is placed between the front and rear crimping frames 4 and 4.
Is pinched. When the tower 21 is gently lifted in this state, the flange 23 of the tower 21
The tubular body 19 is rotated while abutting against the leaf spring 24, and the flange 23 abuts against the receiving claw 26.

In this state, when the entire tower 21 is lifted upward, the upper receiving claw 18 and the flange 2 of the tower 21 are moved upward.
There is a large gap beforehand between them. When the elevating plate 12 is raised by operating the hydraulic cylinder 11 in this gap, the leaf spring 24 of the upper receiving claw 18 provided on the elevating plate 12 rotates the cylinder 19 while abutting against the surface of the flange 23, and the load is received. The claw 18 contacts the flange 23. Here, the lifting plate 12
The dowel pin 14 is inserted into the hole 13 that fits the concave portion 15 formed on the lower side of the cylinder, and the operation of the hydraulic cylinder 11 is stopped.

In this state, the tower 21 is located between the two crimping frames 4 and 4.
At this time, the hydraulic cylinders 11 and 11 are conveyed and the tower 21 is set to the conveying posture while gradually lifting the tower 21 as shown in FIGS.

Then, as a result of previously examining the height relationship of the tunnel, the pedestrian bridge, etc. in the tower transportation path, and the unevenness of the road, etc., the passenger 3 riding on the rear trailer 30
The tower 21 is transported to the installation position of the wind power generator while operating the hydraulic cylinders 8, 8 based on the road visibility information of the second road.

The engaging support means during the transportation of the tower 21 having the largest diameter is as described above. However, when transporting the tower 21 having a smaller diameter, the lower loading catch 2
6 is raised to the next or uppermost insertion hole 25, and the upper end of the tower 21 is engaged and supported by a load receiving claw 18 provided at the upper end of the elevating plate 12 lowered.

[0028]

According to the configuration of the present invention as described above,
The following effects can be obtained.

A long tower having a cylindrical structure for a wind power generator is directly engaged and supported between a crimping frame having a hydraulic cylinder mounted on a towing vehicle and a rear trailer, and can be transported in a low posture. Also, since the garter frame is not used at all, the tower can be conveyed in a correspondingly low attitude. On the other hand, since the crimping frames can be moved up and down by hydraulic cylinders, respectively, they can be applied to unevenness conditions of a tunnel, a pedestrian bridge, or the like.

According to the second aspect, since the size of the crimping frame is substantially equal to the maximum diameter of the cylindrical structure, the passage of the tunnel or the pedestrian bridge can be made by predicting the height of the tunnel or the pedestrian bridge larger than the maximum diameter in advance.

According to the third aspect, since the upper and lower receiving claws can be respectively raised and lowered, a tower having a small maximum diameter can be easily engaged and supported, and can be transported.

According to the fourth aspect, the height setting position of the elevating plate can be held by the knock pin, and an accident can be solved.

According to the fifth aspect of the present invention, since the leaf springs are provided so as to be pressed against the flanges of the tower, all of which are held by the receiving claws, the fixing of the receiving claws can be easily performed without requiring human power.
