Description

For example, when transporting a long heavy object such as a long and heavy drying furnace used for waste disposal, the present invention is carried out or carried in from a narrow entrance of the building while avoiding obstacles inside and outside the building. The present invention relates to a method for conveying a long heavy object for conveying a heavy object.

Conventionally, in order to avoid surrounding obstacles in a narrow space, a transport cart that can turn a transport object in a predetermined transport direction has been used.
For example, as shown in Patent Document 1, in the work of transporting long heavy objects such as towers and tanks, avoiding obstacles and the like around corners and transport paths, and changing the direction of long heavy objects In order to narrow the dead space, a long heavy object can be rotated through a swivel installed on a transport carriage.

Japanese Utility Model Publication No. 5-5564 (FIGS. 1, 2 and 7)

However, the conventional method for transporting long heavy objects still has the following problems to be solved.
Even if it is possible to turn a long heavy object in a predetermined transfer direction by turning the turntable, the movement of the transfer carriage itself is limited, that is, because the rotation radius of the transfer carriage is large, dead space is reduced. For example, long heavy objects installed in a narrow space building can be carried out or carried in from a narrow entrance of the building, and obstacles around the conveyance path outside the building can be avoided. Could not be replaced by transport.

The present invention has been made in view of such circumstances, and loads and unloads long heavy objects into and out of a narrow space through a narrow entrance, and avoids obstacles around the conveyance path outside the building. It is an object of the present invention to provide a method for conveying a long heavy object that can be carried out.

Easy to carry in.

Next, embodiments of the present invention will be described with reference to the accompanying drawings for understanding of the present invention.
Here, FIG. 1 is an overall layout diagram illustrating a method for conveying a long heavy object according to an embodiment of the present invention, and FIGS. 2A and 2B are respectively a method for conveying the long heavy object. FIG. 3 is a front view showing a state in which a dryer is mounted on a swivel of a transport device for long heavy goods to be used, a side sectional view, and FIG. 3 is a configuration of a transport apparatus for long heavy goods used in the method for transporting the long heavy goods. FIG. 4 is an explanatory view showing the arrangement of wheels of a transport carriage of a transport device for long heavy goods used in the transport method for the long heavy goods, and FIG. 5 is a long heavy goods in the transport method for the long heavy goods. FIG. 6 is a diagram illustrating a moving process of the transport device and the dryer. FIG. 6 is a diagram illustrating a case where a dryer is mounted on a swivel of a transport device for a long heavy object by a crane truck in the building, or a dryer is mounted on a long heavy object. It is explanatory drawing which shows the operation | work which unloads from the turntable of a conveying apparatus.

As shown in FIG. 1, FIG. 2 (A), (B), and FIG. 3, the long heavy article conveyance apparatus 10 used for the long heavy article conveyance method according to the embodiment of the present invention is, for example, When replacing the dryer 12 which is an example of a long heavy article provided in the building 11 having a narrow entrance 13 and a narrow interior, the dryer 12 is carried out and carried in via the entrance 13 of the building 11; This is a device for turning and transporting the placed dryer 12 while avoiding obstacles inside and outside the building 11.

The long heavy-duty conveying device 10 can travel in any direction including turning (in addition to normal straight traveling, oblique traveling and lateral traveling), and the same direction as the length direction of the dryer 12 installed. And a turntable 15 that can be swiveled by mounting a dryer 12 that is longer than the total length S (for example, 5 to 15 m) of the transfer carriage 14 with its center of gravity G mounted. It has. These will be described in detail below. The dryer 12 is a rotary kiln type long and cylindrical heavy object (for example, outer diameter D = 1.5 m or more, length L = 10 m or more, weight W = 20 tons or more) for waste treatment.

As shown in detail in FIGS. 3 and 4, the transport carriage 14 is a four-axle type carriage and is individually driven by eight wheels having four rubber tires, that is, by a hydraulic motor with a reduction gear. Three drive wheels 16 to 18 and five non-drive wheels 19 to 23 are provided. Both the driving wheels 16 to 18 and the non-driving wheels 19 to 23 have a structure that can turn in a horizontal plane. Therefore, for example, the driving wheels 16-18 are rotated at the same speed in a state where the operator selects the traveling mode and all the driving wheels 16-18 and the non-driving wheels 19-23 are controlled to face the longitudinal direction of the carriage. By doing so, the transport carriage 14 can travel straight. In this state, when the operator performs a steering operation, the transport carriage 14 can turn rightward or leftward. In this case, the turning angle of each axis and the rotational speed of the drive wheels 16 to 18 taking into account the turning radius ratio (= R / r) with respect to the turning center O are determined by a computer (not shown) mounted on the transport carriage 14. ).

In addition, when the driving mode is switched and the drive wheels 16 to 18 are rotated in a state where the axis centers of all the wheels are controlled to face the rotation center K, the transport carriage 14 turns around the rotation center K. can do. Note that reference characters R ′ and r ′ in FIG. 4 represent the distance between the rotation center K and the center of the wheel.

As shown in FIGS. 2A, 2B, and 3, a carriage frame 24 having a rectangular frame shape in plan view is provided at the upper end portion of the transport carriage 14, and the carriage frame 24 is a link type hydraulic pressure. It is provided so that it can be raised and lowered by a suspension. A power pack 25 including a hydraulic unit, a control means, and the like is detachably provided at the end of the transport carriage 14 on the non-drive wheels 22 and 23 side.

A fixed frame 26 having a rectangular frame shape in plan view is fixed on the cart frame 24 on the non-drive wheels 19 and 20 side, and the swivel base 15 swivels with respect to the fixed frame 26 via a swivel bearing. A disk-shaped turntable 27 and a cradle 28 that is fixed on the turntable 27 and supports the dryer 12 are provided. A hydraulic source of a hydraulic motor that drives the swivel base 15 to rotate is supplied from a hydraulic unit of the power pack 25. As an example, the vehicle width T of the transport carriage 14 is 2500 to 4000 mm, the vehicle height P is 1000 to 2000 mm, and the mounting height U of the swivel base 15 is 500 to 1000 mm.

The position where the swivel base 15 is attached to the carriage frame 24 of the transport carriage 14 via the fixed frame 26 is determined based on the following concept. That is, as shown in FIG. 2A, the assumed center-of-gravity position G of the dryer 12 having a length L longer than the total length S of the transport carriage 14 is coincident with the turning center Q of the turntable 15 in plan view. The dryer 12 is mounted on the swivel base 15, and it is possible to avoid the dryer 12 and the transport carriage 14 from interfering with surrounding obstacles due to the traveling of the transport carriage 14 and the turning of the swivel base 15. It is determined in consideration of the axial weight (wheel weight) of the transport carriage 14. As a result, stable running and turning without interference is possible. Reference numerals 29 to 32 in FIGS. 1 and 5 represent processing facilities or processing apparatuses related to the processing of the dryer 12, that is, obstacles during transport of the dryer 12. In FIG. 1, reference numeral 41 denotes a carry-in path for the transport carriage 14, reference numeral 44 denotes a corner portion of the carry-in path 41, and reference numeral 45 denotes a carry-out path for the transport carriage 14.
