Description

[Detailed explanation of the invention] This invention is designed to lift the ALC plates (lightweight aerated concrete plates) to create a gap for passing the hanging rope so that they can be sorted from the top using a crane, etc. This relates to the ALC version lifting device.

Multiple sheets of ALC plates are stacked together and delivered to the site in one package, and construction at the site is carried out by separating the stacked ALC plates. By the way, the weight of ALC plates varies depending on the thickness, length, width, etc., and the weight can be about 100 kg per sheet. When sorting this ALC plate using a crane, etc., conventionally, the ALC plate to be separated is moved sideways and then one end (longitudinal end) is lifted to create a gap between it and the ALC plate below. A sling was made and a hanging rope was passed through this gap.

However, in this conventional method, there is considerable abrasion resistance between the ALC plates, and force is required to shift the ALC plates horizontally. Moreover, it takes no effort to move the ALC version above the shoulder side to the side. Furthermore, as mentioned above, the ALC version is heavy, for example, 100 kg, so the load to lift one end of it is quite large, reaching 50 kg. For this reason, it takes a lot of effort and time to hang the ropes during the sorting work, and there is an unavoidable problem that the sorting work cannot be carried out efficiently.

The present invention was devised to solve the above-mentioned conventional problems, and uses the principle of a screw to immediately and easily lift the side edge of the ALC plate without sideways shifting, thereby creating a gap for the passage of the hanging rope. Simple and easy to make
Aims to provide ALC version lifting equipment.

The present invention will be explained below with reference to illustrative embodiments.

In the figure, reference numeral 1 indicates two opposing support columns, which are connected to each other by connecting members 3 at the upper and lower ends so as to form a rigid rectangular pipe frame 2.

Reference numeral 4 denotes two supporting arms facing each other, which are connected by a connecting member 5 installed across the upper side fence. A pin 6 is provided at the opposing end of the support arm 4, and a locking ring 7 is provided at the base end with a vertical opening. The support arms 4 are each attached to the column 1 at a locking ring 7 so as to be tiltable downward and movable up and down.

Reference numeral 8 denotes a friction-type stopper mechanism for stopping the downward movement of the support arm provided between the base end of the support arm 4 and the surface of the support arm 1 when the support arm 4 is tilted downward. The lower end and the upper end of the inner surface on the side opposite to the arm press against each other, and the frictional force generated therebetween attempts to stop the downward movement of the support arm 4.

In order to generate a large frictional force between the support column 1 and the base end of the support arm 4, the surface of the support column 1 may be made rough or uneven in the vertical direction.

Reference numeral 9 denotes two levers extending in a direction perpendicular to the opposite direction of the pillars, and a rigid U-shaped pipe frame 1.
They are connected to each other by handles 11 at their proximal ends so as to form 0. A pin 12 is provided at a position where the tip and base ends of the lever 9 are internally divided, for example, by 1:7, and protrudes toward the opposite side of the lever.

Reference numeral 13 denotes a support piece, which is vertically rotatably attached to the tip of the lever 9 through a pin hole 14 provided in the support piece and the pin 6;
can be replaced with one corresponding to the end shape of ALC plate 15. For example, when a recessed groove 16 having a semicircular or trapezoidal cross section is provided at the end of the plate, a protrusion 16 having a semicircular or trapezoidal cross section fits into the recessed groove 16.
7 is used, or when a protrusion such as a trapezoidal cross section is provided at the edge of the plate,
A support piece 13 is used which is provided with a concave groove having a trapezoidal cross section or the like that fits into the protrusion.

Reference numeral 18 denotes a protrusion for temporarily fixing the support piece, which is provided on one of the two opposing parts so as to be able to come into contact with the other when the support piece 13 is placed along the lever 9.

In the above configuration, the support piece 1 at the tip of the lever 9
3 into the end of the uppermost ALC plate 15 (in the drawing, the groove 16) from the side end side, and engage it.
If the handle 11 at the base end of the lever is lifted after the lever is erected, the tip of the support arm 4 will be lifted via the lever 9, and the locking ring 7 at the base end of the support arm will not lock with the support post 1. From there, the support arm 4 can be pulled up to a predetermined height by rotating the lever 9 upward about the tip thereof.

Next, when the handle 11 at the base end of the lever is pushed down, as the lever 9 rotates downward around the tip, the support arm 4 adds the forward downward rotational moment from the lever 9 to the rotational moment due to its own weight. The locking ring 7 at the base end of the support arm 4 instantly locks with the support 1, so that the pin 6 at the tip of the support arm 4 tilts downward about the base end.
A force is generated around the center, and this force lifts the uppermost ALC plate 15 around its one end, creating a gap in the lower part of the ALC plate 15 through which a suspension cable from a crane or the like can be passed. It can be made easily and reliably.

After passing the suspension cable through, lift the handle 11 and move the locking ring 7 at the base end of the support arm 4 upward via the lever 9 to a position where it is easy to remove the support piece 13 at the tip of the lever from the ALC plate 15. By tilting the lever 1 toward the opposite side of the ALC plate around the lower end, the support piece 13 at the tip of the lever can be removed from the ALC plate 15.

As mentioned above, the present invention has an extremely simple configuration,
Not only can it be manufactured cheaply and easily, but
It is easy to attach and use to the ALC version, and can make sorting work easier.
