Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a member transfer / installation machine suitable for a narrow construction site such as underground of a building.

[0002]

2. Description of the Related Art For example, a large-scale parking facility is usually installed in the basement of a building in many cases. is there. (1) The installation location is narrow. (2) There is a limit to the entrance of members, and normally there is only one place per lane. (3) The transport distance from the member loading port to the installation location is long,
It is a narrow space. (4) Since it is not possible to use conventional heavy machinery at the installation site during construction, it is necessary to develop a dedicated machine for efficient installation work. By the way, at the construction site of this kind of underground building,
When loading construction materials into the underground site, assemble and integrate the materials near the material loading entrance, set casters under the assembled materials, transfer to the installation position, jack up and remove the casters, then jack. Installed down.

[0003]

That is, conventionally, as shown in FIG. 7, a member carried in from a member carrying-in port is integrated and assembled in the vicinity of the member carrying-in port, and the assembled member 7c is assembled.
Then, the caster is once jacked up, and the caster 10 for movement is set at the lower part of the member, and then the jacked down member is placed on the caster 10. afterwards,
The assembled member 7c is conveyed to the installation position by pulling it manually or by a winch. The conveyed member 7c is jacked up again to remove the casters 10 and then jacked down to install it at a fixed position. However, with such a means, a great deal of labor and time are required for jacking up, jacking down, and member transportation, so that the installation efficiency is significantly reduced.

The present invention has been proposed in view of the above circumstances, and it is possible to convey and install members by a machine, greatly reduce labor and time, and improve installation efficiency at an economical and narrow construction site. It is an object of the present invention to provide a machine for installing and transporting a member for use in a vehicle.

[0005]

To this end, the present invention provides
A long carriage in the front-rear direction having a pair of left and right wheels at the front and rear ends, and a erected on the front and rear ends of the trolley, rotatable about a vertical center line and fixed to a desired phase. Lifting machine movably supported by front and rear struts, and a pair of parallel rails laid along the longitudinal direction of the horizontal rectangular beam whose central portion is fixed to the upper ends of the struts. , A counterweight and endless wires which are wound around pulleys respectively arranged at four corners of the horizontal rectangular beam and move in opposite directions by interlocking the lifting machine and the counterweight with each other. .

[0006]

With this structure, as shown in FIG.
When the member 7a is hoisted by the lifting machine 4, a counterweight 5 having a weight corresponding to the weight of the member 7a is attached to the beam 3 to prevent the machine from tipping over. The lifting machine 4 and the counterweight 5 are shown in FIG. They are connected to each other by the endless wire rope 6a shown. Therefore, when the lifting machine 4 traverses, the counterweight 5 automatically moves in the direction opposite to that direction, and prevents the machine from falling.
As shown in FIG. 1, the column 2 can be adapted to various construction site heights by removing a part of the column 2 in accordance with the ceiling height of the installation site. Further, as shown in FIG. 3, a pivot bearing 11 is attached to the lower part of the column so that the column can rotate, and a rotation stop bolt 12 after the column is rotated is provided. By making the support column rotatable, it is possible to pass even if there is a wall or the like having only an opening of about the width dimension of the carriage 1a in a part of the transport path (FIG. 5). If necessary, as shown in FIG. 4, a guide metal piece 13 is attached to the center of the carriage 1a to prevent meandering when the carriage 1a travels, and is guided by a guide rail 14 attached to the floor surface.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, one embodiment of the present invention is shown in FIG.
II-II arrow plan view, FIG. 3 is an enlarged cross-sectional view showing the column lower end portion III of FIG. 1, FIG. 4 is a IV-IV arrow cross-sectional view of FIG. 1 (B), and FIG. 5 is FIG. 1 (A). Similarly, FIG. 6 is a front view showing a state in which the beam is rotated at a right angle, and FIG. 6 is a front view showing how to lift and convey the members in FIG.

In the apparatus of the present invention, as shown in FIG. 1, a pair of left and right carriage wheels 1b are attached to the lower surfaces of the front and rear ends of a motor-driven self-propelled carriage 1a that is long in the front-rear direction, and the front and rear end portions of the upper surface are attached. Are front columns 2F and rear columns 2 of equal length
R is established, and the central portions of the rectangular horizontal beams 3 are fixed to the upper ends of the columns 2F and 2R in a T shape. Each strut is formed by connecting a plurality of segments with a flange, and its total height can be adjusted by increasing or decreasing the number of segments.

Here, as shown in FIG. 2, the horizontal beam 3 forms a rectangular frame having a deformed Japanese letter shape, and a movable lifting machine 4 is provided on one of a pair of rails extending in the longitudinal direction thereof.
On the other hand, a movable counterweight 5 is slidably hung vertically, and the hoisting machine 4 and the counterweight are moved by the movement of the endless wire rope 6a which is wound around four pulleys 6b arranged at each corner of the rectangular frame. 5 is movably supported while maintaining point-symmetrical positions with respect to the center of the column.

The lower portions of the columns 2F and 2R are supported on the carriage 1a by pivot bearings 11 as shown in FIG. 3, and the flange holes of the flanges 2f projecting from the lower portions of the columns and the protrusions on the carriage are provided. Each support column can be set in a desired phase by the rotation stop bolt 12 penetrating the flange hole of the upper end flange 1d of the support cylinder 1c.

Further, as shown in FIG. 4, a bifurcated guide portion 13 is provided on the center line of the lower surface of the carriage 1a so as to be loosely fitted to a guide rail 14 laid on the base. In order to prevent the vehicle from meandering.

In such a structure, since the width of the carriage 1a is relatively short, both beams 3 are rotated so as to be parallel to the longitudinal direction of the carriage as shown in FIG. However, it can be moved by self-propelled or if necessary, it can be moved manually, and at that time, depending on the circumstances of the construction site, the height of the support column can be freely selected by increasing or decreasing its segment.

Here, when carrying the member 7a to the construction site, as shown in FIG. 6, the member 7a is slid on the hook of the lifting machine 4 via the wire rope 8 and then the lifting machine 4 is moved. Thus, it moves in the direction of the arrow 9 and is placed at the position 7b on the carriage 1a.

Further, when loading the members on the trolley,
As shown in FIG. 6, when the member 7a is hoisted by the lifting machine 4, a counterweight 5 having a weight corresponding to the weight of the member 7a is attached to the beam 3 to prevent the machine from tipping over. The counterweights 5 are connected to each other by a wire rope 6a shown in FIG. Therefore, when the lifting machine 4 traverses, the counterweight 5 automatically moves in the direction opposite to that direction, and prevents the machine from falling. By removing a part of the pillar 2 in accordance with the ceiling height of the installation site, various pillar conditions can be met. Further, as shown in FIG. 3, the lower part of the column is attached with a pivot bearing 11 so that it can rotate, and a rotation stopper 12 after the column rotates.
Is provided. By making the pillar rotatable,
Even if there is a wall or the like having only an opening of the width of the truck 1a in a part of the conveying path, as shown in FIG.
It can be cleared by turning 0 °.
