Description

  The present invention relates to a structure of a suspended loading platform used when lifting a pallet for cargo handling.

A pallet used for physical distribution is a loading / unloading board stand for loading luggage, and is used for loading / unloading work in factories, trucks, containers, warehouses, and the like.
When transporting a general pallet, a load is placed on the pallet bed during transportation, and a forklift or handlift claw is inserted into a horizontal space below the bed (hereinafter referred to as “underloading space”). Lift and handle.
However, when handling with a truck crane, etc. instead of a forklift, it will be lifted using a wire, but in that case there is no member equivalent to the “claw” of the forklift, so some effort is required for the connection between the pallet and the wire It becomes.
As an example of the handling, a method is known in which a pipe is inserted into the space under the loading platform of the pallet and penetrated to the opposite side, and a wire is hung on both ends of the pipe exposed from the pallet.
In this method, there is a problem that the pipes on both sides are likely to move toward the center in the space under the loading platform when lifting with a wire, and there is a possibility that the load may collapse due to a loss of balance.
As a solution to such a problem, a method as described in Patent Document 1 is known.
The method will be described with reference to FIG. 4. When a bar d is horizontally arranged between two pipes c inserted in parallel under the loading space b of the pallet a and is lifted by a wire e, both pipes c It is a structure that prevents the approach of.

JP2009-269708A.

In the suspended loading platform structure as shown in FIG. 4, the approach of the pipe c can be prevented.
However, since only the end of the pipe c is inserted into the ring attached to the slide bar d, there is a risk that the ring slides on the surface of the pipe c and the wire e is detached.
In addition, since the area where the pipe c and the pallet a are in contact with each other is small, the pipe c and the pallet a are easily slipped in the space b, and the load acting on the pallet a is also locally concentrated. there were.

  The structure of the hanging load platform of the present invention that solves the above-described problems includes a main girder that receives the load of the load to be loaded, a suspension member that is attached to the end of the main girder, and a main girder that faces one main girder. The main girder is composed of two parallel-arranged square pipes and a connecting member for connecting the two square pipes, and the suspension member is a hollow short part disposed in parallel. It consists of a pipe, a base plate that receives both short pipes, and a suspension plate that stands vertically between the short pipes of the base plate, and the spacer is between the pipe receiver that covers the square pipe and the pipe receivers. It is characterized by comprising a spacing material connecting the two.

Since the structure of the hanging platform of the present invention is as described above, the following effects can be obtained.
<1> The suspension member of the suspension platform is attached to the end of the main girder and has a structure that allows the hook and shackle at the tip of the wire to be securely engaged, so there is a risk that the wire will come off while it is being lifted There is no.
<2> Since the spacer is interposed between the main girders that bear the load of the load, the main girders inserted into the space under the loading platform of the pallet are not likely to move inside, and are safe.
<3> Since the surface of the square pipe that constitutes the main girder abuts in the space under the loading platform is a flat surface, it is difficult to slip and does not collapse during loading operations.
<4> Since each main girder consists of two square pipes, the pallet is supported by a total of four square pipes. Therefore, the contact area between the pallet and the pipe can be widened, and the risk of damage to the pallet is small.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the structure of a suspended loading platform according to the present invention will be described in detail below with reference to the drawings.

<1> Overall configuration.
The suspension platform according to the present invention maintains a distance between a main girder 1 that receives a load of a load to be loaded, a suspension member 2 that is attached to an end of the main girder 1, and another main girder 1 that faces one main girder 1. The spacer 3 is configured.
The pallet a and the load thereon are lifted by inserting the suspending platform into the space b under the pallet a and lifting the suspended platform.

<2> Main digit.
The main girder 1 is composed of two square pipes 11 arranged in parallel and a connecting member 12 for connecting the two square pipes 11.
Thus, although the space | interval between the square pipes 11 of the main beam 1 is decided by the dimension of the connection material 12, the dimension is set to the width | variety (about 10 cm) of a human hand.
Then, in the operation | work which inserts and pulls out the main girder 1 in the under-carrying space b of the pallet a, it can hold | grip the connection material 12 and can carry out work | work in good balance.
The height of the square pipe 11 of the main girder 1 is formed to be smaller than the height of the space under the loading platform b.
The length of the main beam 1 is configured to be longer than the width of the pallet a that is the object of lifting.
Therefore, when the main beam 1 is inserted into the space b under the loading platform of the pallet a, both ends of the main beam 1 are exposed to the outside from both end surfaces of the pallet a.
Moreover, the upper surface of the two square pipes 11 arranged in parallel comes into contact with the inner surface of the undercarriage space b when lifting.
As will be described later, the end of the main beam 1 is covered with a short tube 21 of the suspension member 2, but a pin insertion hole 13 is opened closer to the end than the position of the short tube 21.
When a pin is inserted into the hole in a direction crossing the axis of the square pipe 11, the suspension member 2 can be prevented from being detached from the square pipe 11.
In this way, two main girders 1 having the suspension members 2 attached to the end portions are prepared.

<3> Hanging member.
The suspension member 2 includes two hollow short tubes 21 arranged in parallel, a base plate 22 that receives both short tubes 21, and a suspension plate 23 that stands vertically between the short tubes 21 of the base plate 22. Configure.
The short tube 21 is a hollow tube having both ends penetrating therethrough.
The inner shape of the short pipe 21 is similar to the outer shape of the square pipe 11 of the main beam 1 and is formed to be slightly larger than the outer diameter of the square pipe 11.
Therefore, it is easy to insert and cover the short pipe 21 from the end of the square pipe 11 of the main beam 1.
The pin used for the pin insertion hole 13 is preferably fixed to the suspension member 2 with a chain or the like.
Two short tubes 21 are arranged in parallel with the same interval as the two square pipes 11 of the main beam 1, and a base plate 22 is attached below the two short tubes 21.
The base plate 22 is a rectangular steel plate, and a suspension plate 23 is erected vertically between two short tubes 21 spaced apart from each other.
Therefore, the base plate 22 and the suspension plate 23 are formed in an inverted T shape.
The suspension plate 23 is also a rectangular steel plate, but has an engagement hole for engaging a hook or shackle.

<4> Spacer.
The spacer 3 includes a pipe receiver 31 that covers the square pipe 11 of the main beam 1 and a spacing member 32 that connects the pipe receivers 31.
The pipe receiver 31 is a groove plate opened downward in an inverted U shape, and its inner shape is similar to the outer shape of the square pipe 11 and is formed with a slightly larger dimension.
Two pipe receivers 31 arranged in parallel are connected by a spacing member 32 made of a steel bar or the like.
The spacing member 32 holds the spacing between the two main beams 1.
Therefore, the length of the spacing member 32 is such that when the pipe receiver 31 is put on the inner corner pipe 11 of the two main girders 1, the outer corner pipe 11 is placed on the inner wall of the load space under the loading platform b of the pallet a. The dimensions are such that they can be placed close to each other.

<5> Usage method.
As described above, the pallet a is formed with a space under the loading platform b into which a claw such as a forklift is inserted.
This undercarriage space b is an open end surface b1 with both end surfaces open and is a rectangular cavity with walls b2 on both side surfaces. From the open end surface b1 of the undercarriage space b, the main space is located in the vicinity of the walls b2 on both sides. Insert digit 1 each. At this time, the two main girders 1 are not integrated.
Since the main beam 1 is longer than the distance between the opening end surfaces b1, both ends of the main beam 1 are exposed from the opening end surface b1.
By fitting the pipe receiver 31 of the spacer 3 to the end portion of the main girder 1 exposed in this manner, the position between the main girder 1 can be fixed.
Before and after that, the short pipe 21 of the suspension member 2 is moved from both ends of the square pipe 11 onto the axis of the main beam 1.
Since the inner shape of the short pipe 21 of the suspension member 2 is slightly larger than the outer shape of the main girder 1, the short tube 21 of the suspension member 2 can be inserted into the end of the main girder 1. 2 are united.
Then, at the end portion of the main beam 1, the suspension plate 23 of the suspension member 2 rises vertically between the square pipes 11.
After that, since the pin insertion hole 13 is opened to the end side of the main beam 1 from the position of the short pipe 21, the pin is inserted into the hole in a direction crossing the axis of the square pipe 11.
Then, the suspension member 2 does not slide on the surface of the main beam 1.
In this state, the hooks and shackles of the wires are engaged with the holes of the suspension plate 23 to lift the loaded pallet a.
It is more preferable to use a pin that has been processed to prevent punching.

<6> A structure in which no pin insertion hole is provided.
It is also possible to adopt a structure in which the pin insertion hole 13 is opened only in the square pipe 11 and is not opened on the side surface of the short pipe 21.
In that case, the position of the short tube 21 is aligned so as to be concentric with the pin insertion hole 13 of the main girder 1, and the pin is inserted.
