DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a supporting device for erecting a long member such as a column member.

[0002]

2. Description of the Related Art In general, a column member having a ground structure is firstly composed of two members.
It is lifted horizontally by a single crane and gradually erected. However, in places where the site is narrow and only one crane can be installed, one crane must lift and raise the capital. In this case, it is necessary to safely and efficiently erect the column member while supporting the column base.

Heretofore, as a column base supporting device of this type, a column base is supported by a bogie so that the column base can be rotated with respect to a horizontal axis, and the bogie is supported by rails when the column head is lifted by a crane. It was designed to be guided.
However, this conventional apparatus has the following problems. (1) Since the movement of the bogie is regulated in one direction by the rail, the range of use is limited and the versatility is poor. (2) It is difficult to lay rails on temporary premises with narrow column members. (3) Since the erecting direction of the pillar member is limited to the laying direction of the rail, the pillar member must be lifted once and then mounted on the carriage.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to make it possible to effectively use a site and to reduce construction costs. It is another object of the present invention to provide a support device for erecting a long member capable of safely and efficiently erecting a long member.

[0005]

SUMMARY OF THE INVENTION According to the present invention, there is provided a support device for erecting a long member, comprising: a base frame having a front wheel for sliding and a rear wheel for sliding; A drive wheel provided to be steerable, an elevating gantry provided on the base gantry so as to be able to move up and down, a rotary pedestal rotatably pivotally attached to the elevating gantry and attaching a leg of a long member,
It is characterized by comprising. Further, a lateral moving wheel is provided at a lower end of a sliding body vertically provided below the elevating pedestal near the rear wheel for sliding. Further, a brake shoe is provided at a lower end of a sliding body vertically suspended below the elevating pedestal near the front wheel for sliding. Still further, a cylinder for returning the rotary base to the initial position is provided.

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a base gantry to which front sliding wheels 2, 2 and rear sliding wheels 3, 3 are rotatably mounted. In addition, in this specification, the said base stand 1 is said front wheel 2 for sliding.
And the direction of travel by the rear wheels 3 (see FIG. 1).
(In (A) and (B), the horizontal direction) is referred to as the sliding direction,
The direction perpendicular to the direction (vertical direction in FIG. 1A) in a plan view is referred to as a lateral movement direction.

A ground pressure adjusting cylinder 4 is provided at the front end of the base stand 1 in the sliding direction. 4a is the cylinder rod. A turning shaft 7 of a driving wheel 6 is rotatably attached to the cylinder 4 via an arm 5. A power unit 8 such as an engine or a motor is attached to the upper end of the turning shaft 7 so as to rotate the drive wheels 6. Reference numeral 9 denotes a steering wheel for steering the drive wheel 6.

[0008] Reference numeral 10 denotes an elevating platform, and two sliding bodies 10a and 10b vertically suspended therefrom are guided by guides 1a formed on the base platform 1, and
It is configured to be able to move up and down (up and down). Reference numeral 11 denotes an elevating cylinder, the base end of which is pivotally attached to the base 1 via a pin 11a, and the distal end of a cylinder rod 11b of the elevating cylinder 11 is a pivot shaft 1
It is pivoted to 2. The pivot shaft 12 is mounted on the lift base 1.
0 is attached to the bracket 10c.

A laterally moving wheel 13 is rotatably attached to the lower end of a sliding body 10a hanging from the elevating gantry 10. The axle of the laterally moving wheel 13 is orthogonal to the axle of the front sliding support wheel 2 and the rear sliding support wheel 3 so that the device can be moved laterally when it touches the ground. On the other hand, the lower end of the sliding body 10b is a brake shoe 14, which fixes the device to the ground when it is grounded.

Reference numeral 15 denotes an L-shaped rotating pedestal, which is constituted by two plates orthogonal to the L-shape.
2 and is rotatable. Reference numeral 16 denotes an initial position return cylinder, which is mounted between the elevating pedestal 10 and the L-shaped rotary pedestal 15, and
5 is rotated to return to the initial position. 15a is a pillow material.

Next, a description will be given of the work of erecting the column member by the apparatus of the above embodiment. First, as shown in FIG. 2, the cylinder rod 4a of the ground contact pressure adjusting cylinder 4 is contracted to ground the drive wheel 6, and further contracted so that the front sliding wheel 2 near the drive wheel 6 is grounded. , And the base frame 1 is supported at the three points of the drive wheel 6 and the remaining rear sliding wheels 3.

In this state, the drive unit 6 is driven to rotate by the power unit 8 and, while the handle 9 is being operated, as shown in FIG.
It is moved below the pillar member P placed on it.

In the above operation, the apparatus cannot be accurately positioned below the lower end of the column member P.
If it is located sideways, as shown in FIG. 4, the cylinder rod 11b of the elevating cylinder 11 is contracted to lower the sliding body 10a of the elevating gantry 10, and the lateral movement wheels provided at the lower end thereof When the rear wheel 3 for sliding is separated from the ground while the ground 13 is grounded, the base mount 1 moves the wheels 13 for lateral movement and the wheels 3
Supported by points.

In this state, when the handle 9 is operated to rotate the drive wheel 6 in a direction parallel to the lateral movement wheel 13, the base mount 1 is moved sideways as shown in FIG. It can move to the lower side of the column member P.

Next, as shown in FIG. 6, when the cylinder rod 4a of the ground contact pressure adjusting cylinder 4 is extended, the drive wheel 6 separates from the ground, and the lift base 1
The brake shoe 14 provided at the lower end of the zero slide 10b is grounded, and the base gantry 1 can be fixed to the ground.

In this state, as shown in FIG. 7, when the elevating gantry 10 is raised by the elevating cylinder 11, the L-shaped rotary pedestal 15 is raised and the lower end of the column member P is raised to support it. I do. At this time, the temporary placement table 17 supporting the lower part of the column member P during the temporary placement is removed.

The upward movement of the L-shaped rotary pedestal 15 by the lifting cylinder 11 separates the laterally moving wheel 13 and the brake shoe 14 from the ground and grounds the front sliding wheel 2 and the rear sliding wheel 3. As shown in FIG. 8, when the upper end of the column member P is lifted by the crane, the base gantry 1 follows the sliding movement in the sliding direction and the column member P can be erected.

[0018]

Advantages of the Invention 1) Since there is no need to lay rails,
The site can be used effectively. 2) There is no need to install or remove rails, which can reduce construction costs. 3) It is safe because the temporary stand can be removed before erecting work. 4) Since the device can be moved in any direction and position, the device can be easily and quickly moved to the temporary storage site for the column members, and the operation time can be reduced.
5) It can be moved to an arbitrary place with the column member mounted, and can be used as a simple moving device.
