Abstract

PURPOSE:To facilitate the set to a carrying and constructing position with the less number of construction at the horizontal construction of an ALC board, and reduce the dangerousness in a high place. CONSTITUTION:A single shaft type hand dolly used at the horizontal construction of an ALC board 12 is formed of a hanging beam 16 extending forward with an axle (single shaft) 14 as the center, a handle beam 18 extending backward, and an ALC board fastener 20 connected to the hanging beam 16. The ALC board fastener 20 has a nipping pair part 2 for horizontally fastening and holding the ALC board 12, and is connected to the hanging beam 16 through a hanging tool 28 in such a manner as to be attachable/detachable, and rotatable on the axial vertical surface.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a single-axle type hand truck used for horizontally installing ALC plates (cellular concrete plates).

[0002]

2. Description of the Related Art Conventional Problems A
When the LC plate was installed horizontally, the transportation set was almost manually operated. However, one ALC plate weighs nearly 100 kg, and at least two people need to carry it out by hand in order to carry it and set it in the construction position, which requires a lot of man-hours and is dangerous. Accompanied. In particular,
When working on roofing materials, high places such as the second floor, the degree of danger increases.

In view of the above, the present invention is for horizontal ALC plate horizontal installation, which can be easily carried and set at the installation position with a small number of steps, and the risk at high places can be reduced. The purpose is to provide a cart.

[0004]

A hand truck for horizontal construction of ALC plates according to the present invention solves the above problems by the following constitution.

A single-axle type hand truck used for horizontally installing an ALC plate, which has a hanging rod extending forward, a handle rod extending backward, and a hanging rod around an axle (single axis). The ALC plate fastener is connected to the ALC plate fastener, and the ALC plate fastener has a sandwiching pair part for horizontally fastening and holding the ALC plate, and is attachable to and detachable from the hanging rod via the hanging tool. It is characterized in that it is rotatably connected on a plane perpendicular to the direction.

[0006]

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

(1) A single-axle type hand truck used for horizontally installing the ALC plate 12, which is a hanging rod 16 extending forward around an axle (single axis) 14.
And a handle rod 18 extending rearward and an ALC plate fastener 20 connected to the hanging rod 16 are prerequisites. Specifically, it is as follows.

In this embodiment, the motorcycle 21 is a single shaft type.
For example, a unicycle or a coaxial tricycle may be used.

A suspension rod holding frame 24 is formed on the front side of the inverted triangular carriage frame 22 rotatably supported by a single shaft. And the hanging rod holding frame 2
The hanging rod 16 having a U-shaped end plate connected to the upper pipe beam of No. 4 and provided with a stop plate portion 16a at the end is also paired with the handle rod holding pipe 22a forming the upper side of the inverted triangle of the bogie frame 22. The respective handle rods 18 are held slidably. Here, the slidable position is not necessarily required, but it is desirable to make it compact (see the chain double-dashed line in FIG. 1) when carrying a carrier by car or storing it in a warehouse. In response to the,
The handle rod 18 and / or the hanging rod 16 can be expanded and contracted,
It is possible to make the entire length of the carrier vehicle optimal for a small turn. Although not shown, the handle rod 18 and the suspension rod 16 can be fixed to predetermined positions with wing bolts or the like.

(2) Here, in the present embodiment, the ALC plate fastener 20 has the sandwiching pair portion 26 for horizontally fastening and holding the ALC plate 12, and the hanging rod 16 via the suspending tool 28. Is detachably connected to. Here, the suspending tool 28 is preferably slidable on the suspending rod 16 above the axle from the tip of the suspending rod 16.

Specifically, the sandwiched pair portion 26 is formed of a pair of angle steels, the inside of which is subjected to a non-slip treatment (for example, a rubber plate is attached to the inside), and one of them is provided with a hydraulic jack 30. The cylinder 30a side is fixed to the lower surface of the base end of the fixed channel type base portion 32, and the other is the hydraulic jack 30.
Slide portion 34 fixed to the piston rod 30b side of the
Is fixed to the lower surface of the tip of the. The fastening means is not limited to the hydraulic jack 30 as described above, but may be screw fastening, toggle method, spring method, or the like.

Further, the suspending tool 28 includes the suspending rod 16
And a locking portion 28b formed on the lower surface of the sliding frame portion 28a for locking the ALC plate fastener 20. The locking portion may be a collar-shaped bearing as shown in the drawing, and may be held in the shaft via a locking receiving plate portion 32a formed in the fastener base portion 32, but may be in the form of a hook.

Here, the suspending tool 28 is capable of rotatably suspending the ALC plate fastener 20 on the vertical plane in the axial direction of the suspending rod 16, but it is also rotatable in a horizontal plane. It may be possible.

Further, as shown in the figure, the axle 1 of the two-wheeled vehicle 21.
It is possible to adjust the load balance and height position at the time of transportation and at the time of taking out the ALC plate by forming the axle guide portion 23 that can move the four positions forwardly on the lower side of the front side of the bogie frame body 22 described later. desirable.

(3) Next, the mode of use of the above embodiment will be described.

First, bring the carrier of the present embodiment to the position where the ALC plates 12 are laminated, and suspend the hanging tool 28.
While sliding the to the front end position of the hanging rod 16,
The handle rod 18 is operated to adjust the height of the tip of the hanging rod 16 so that the ALC plate fastener 20 can be clamped on the ALC plate 12 by the clamp pair 26.

Next, the operating lever or the like (not shown) of the hydraulic jack 30 is driven to clamp the ALC plate 12 with the fastener 20 and take it out. At this time, even if the stack height is high, the ALC plate can be easily taken out because it is at the lowest end (vertex of the inverted triangle) of the bogie frame 22.

Next, the axle 14 is moved forward (the position indicated by the chain double-dashed line in FIG. 1), and in that state, the transport vehicle is moved forward, and when the suspending tool 28 is in the proper position, the handle rod 18 is lowered. Down and rotate the ALC plate 12 while floating it up from the other ALC plates 12, and in that state, the ALC plate 12
Transport to the construction position. At this time, as shown in FIG.
If the suspending tool 28 is brought to a position as close to the axle 14 as possible, the force for pressing down the handle rod 18 to lift the ALC plate 12 becomes as small as possible, and the carrying work becomes easy.

When the working position is reached, the suspending tool 28 is positioned at the tip end position of the suspending rod 16 and the transport vehicle is rotated to move the ALC plate 12 to the correct setting position as shown in FIG. Once placed, operate the operating lever of the jack 30 again to loosen the fastener 20, and then
When the handle rod 18 is operated to raise the fastener 20, the fastener 20 is separated from the ALC plate 12.

[0020]

With the above construction, the ALC plate 12 horizontal construction hand truck according to the present invention has the following actions and effects.
It is effective.

(1) Since it can be freely rotated on a vertical plane parallel to the hanging rod, the stacked ALC plates can be lifted and placed and set in a horizontal state, and their workability is good. Is.

(2) Since the ALC plate can be slidably suspended on the suspension rod from the top axle to the tip side,
The lift force can be reduced by applying leverage during transportation, which facilitates transportation.
