Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting work cart for mounting a reinforcing bar net at a desired position in a shield work for erecting reinforced concrete.

[0002]

2. Description of the Related Art In placing rolled concrete for tunnel construction, in order to install the reinforcing bars, loose reinforcing bars can be installed on site, or the reinforcing bars can be assembled on the site after they are assembled into a state of rebar mesh with an arc cross section. How to install is known.

[0003]

Therefore, in either method, the handling of the reinforcing bar and the reinforcing bar net to the mounting position is mostly done manually, which is a laborious task due to heavy labor.

[0004] Therefore, an object of the present invention is to provide a rebar mounting work trolley capable of eliminating the troublesome work and mounting the rebar net accurately and efficiently.

[0005]

According to the present invention, a plurality of pillars are provided at the front and rear of a bogie that is self-propelled on a rail, and a hoist rail for hoists is detachably attached to the top of the pillar. A reversing beam base having an elevating means for mounting and elevating the pillar as a guide is provided, and the reversing beam is rotatably attached to the reversing beam base, and the rebar net is moved to a desired position on the reversing beam. The table is provided so that it can be raised and lowered.

It is preferable that the elevating means is composed of an elevating cylinder pivotally attached to a carriage and a suspension arm, and that the reinforcing bar net is attached to the reversing beam base by a parallel lever and a floor cylinder.

[0007]

In the rebar mounting work trolley configured as described above, the rebar net carried by a material carrier or the like is hung by a hoist to be mounted on the rebar net, and the hoist cylinder is moved to a desired rebar mounting position. When aligning the reversing beam with the center of the tunnel and mounting it on the ceiling, raise the rebar mesh stand with the floor cylinder and mount the rebar net.

When mounting on the right side surface or the left side surface of the tunnel, the reversing beam is rotated to the right or left, and then the rebar mesh net is moved by the floor cylinder to mount the rebar mesh at a desired position.

Further, by using the hoist and the hoist rail, it is possible to move materials and the like in front of and behind the work carriage and load them onto the material carrier etc. without manual labor.

[0010]

Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, the carriage 3 has a plurality of wheels 30.
(4 in each of the left and right in the illustrated example) are provided and configured to be self-propelled by a motor (not shown).

In the drawing, the left side is described as the traveling direction (front part).

The carriage 3 is provided with a circular carriage column 21 having four flat portions at the top and four at the front and rear, and a hoist rail 14 is attached to and detached from the top. It is installed freely.

Referring also to FIG. 2, front and rear hoist rails 13 and 15 are fixed to each other so that the rebar net hoist 8 and the rail hoist 7 can travel.

Further, when using the hoist 8 for the reinforcing bar net, the column 23 can be attached between the hoist 8 and the material carrier 10 if necessary.

Referring to FIG. 3, the inverted beam base 16
Is provided with two left and right base suspension arms 18 so as to be located inside the bogie columns 21, respectively, at the front and rear portions thereof, and the ends of the suspension arms 18 are provided with pins 19 via pins 19.
Inverted beam lifting cylinder 9 having one end pivotally attached to the carriage 3.
Is pivotally attached to the other end of.

Guide rollers 20 are attached to both ends of the pin 19 so as to abut against the inside of the truck column 21.

The reversing beam 2 is rotatably supported by a reversing beam supporting column 17 provided on a reversing beam base 16 and is connected to a motor 6 via a reversing gear set 5.

A rebar net 11 having an arcuate cross section is connected to the reversing beam 2 by a parallel lever 12, and one end of the floor cylinder 1 is pivotally attached to a midpoint 12a of the parallel lever 12. The other end is pivotally attached to the reversing beam 2.

A control panel / power unit 22 is mounted on the rear portion of the mounting carriage.

Therefore, referring to FIGS. 2 to 4, when the reinforcing bar net 4 having an arcuate cross section is transported to the reinforcing bar mounting work cart by the material carrier 10, it is necessary to support the column 23. Attached, hoisting the rebar net with the rebar net hoist 8,
The hoist rails 13 and 14 are moved and placed on the rebar net stand 11, temporarily fixed, and the hoist rail 14 is removed.

Then, the reversing beam is raised by the reversing beam elevating cylinder 9 to align the center of the reversing beam with the center of the tunnel.

When the reinforcing bar net 4 is mounted on the ceiling, the floor cylinder 1 raises the reinforcing bar net 11 to mount the reinforcing bar net on the ceiling (see FIG. 5).

When the reinforcing bar net 4 is attached to the left side surface, the motor 6 is driven to rotate the reversing beam 2 90 degrees to the left,
The rebar net 11 is moved to the left and attached by the floor cylinder 1 (see FIG. 6).

In the same manner, the reinforcing bar net can be attached to the right side surface (see FIG. 7).

If the rebar net 11 is set to the lowest position, the hoists 7 and 8 are used on the hoist rails 13, 14 and 15, and the rebar, rail and other materials in front of and behind the work carriage are used. To load the material on the material carrier 10,
It can be unloaded from the carrier.

EFFECTS OF THE INVENTION Since the present invention is configured as described above, it is possible to mount a rebar net and move materials and equipment without depending on human power, and improve the rebar net mounting accuracy and work efficiency. The worker can be released from the hard work.
