Description

  The present invention relates to a fixing device for wire coils loaded on a loading platform of a truck or a trailer, and more particularly to a fixing device for a plurality of wire coils stacked vertically with a coil shaft directed in the longitudinal direction of the loading platform.

  When wire coils are transported by land, they are transported by truck or trailer. By stacking a plurality of wire coils on a truck or trailer bed in a row with the coil axis in the longitudinal direction of the bed. While maintaining the coil shape, depending on the layout of the factories and warehouses on the shipping side and the receiving side and the cargo handling equipment used, the cargo handling work can be greatly improved. (See, for example, paragraph [0003] of Patent Document 1).

  As described above, it is necessary to fix a plurality of wire coils stacked vertically on the loading platform so as not to cause load collapse or toppling. Conventionally, only the last wire coil is provided with a wire rope and a clamping machine. It was fixed by using it and pushing it forward.

  This fixing method works effectively to prevent the plurality of wire coils from loosening or overturning in the front-rear direction and accompanying falling from the rear part of the loading platform. However, when the truck or trailer travels a sharp curve or turns an intersection, a force that tries to roll around the coil axis is applied to the wire coil by the centrifugal force in the lateral direction (loading bed width direction). For this reason, in this fixing method, since the wire coils other than the tail (or two coils from the tail) have no resistance to lateral force, in severe cases, these wire coils get over the rootstock, Furthermore, there is a risk that the side of the loading platform will be pushed down and fall down on the road. In fact, although there was no personal injury, the occurrence of an accident of dropping the wire coil on the public road has been reported.

  Therefore, there is an urgent need to reliably prevent the rolling of the wire coil in the lateral direction during transportation. For example, as with the conventional method described above, only the last wire coil can be removed using a wire rope and a clamping machine. A method is adopted in which a plurality of wire coils are fixed with a lashing belt one coil at a time after being fixed so as to be pressed forward.

  However, the fixing work of the wire coil is often carried out by the driver of the truck or trailer by itself, and is the same as the above-described conventional method in that only the last wire coil is fixed by the wire rope and the crusher. In addition, the work of fixing a plurality of wire coils one by one with a lashing belt increases, resulting in a problem that the work load becomes very large.

  That is, the fixing operation using the lashing belt is usually performed according to the following procedures (1) to (3).

  (1) First, one end ring portion of the lashing belt is hooked on the hook of the loading platform, and then the lashing belt is hung over the wire coil having a diameter of about 1400 mm, and this operation is performed for each of the plurality of wire coils.

  (2) Next, the top of the loading platform is moved to the other side of the wire coil, and the other end ring portion of the lashing belt is hooked on the hook of the loading platform via the clamping machine.

  (3) Finally, the lashing belt is operated to tighten the lashing belt to fix the wire coil.

  In the procedure of (2) above, if the lashing belt is twisted, it is necessary to eliminate the twist, but at that time the one end ring part of the lashing belt may come off from the hook on the other side, In this case, it is necessary to move to the other side of the wire coil and start again from the procedure (1).

  In addition, after completion of the fixing operation using the lashing belt, it is necessary to hang the seat cover over the plurality of wire coils in order to avoid rain. There is a safety problem such as a work to hang the seat cover while moving on the loading platform across the lashing belt, and there is a high probability that the lashing belt will be caught by the foot, and there is a high possibility of falling from the vehicle.

  In addition, when the lashing belt is tightened while being twisted or when an aging lashing belt is used, the lashing belt may be broken. There was also a risk that the wire coil rolled and dropped from the loading platform.

Embodiment
(Device configuration)
The wire coil fixing device according to the present invention includes a vertical overturn prevention means for preventing the wire coil from falling in the rear direction of the loading platform, and a lateral direction for preventing the wire coil from rolling in the width direction of the loading platform. It is comprised with a direction rolling prevention means.

[Vertical fall prevention means]
As shown in FIG. 1, a wire rope 1 and a load-clamping machine 2 are used in the longitudinal direction fall prevention means constituting the wire coil fixing device of the present invention as shown in FIG. Note that the illustration of the tilt is omitted in FIG.

[Rolling rolling prevention means]
A rolling prevention net 3 and a load-clamping machine 4 are used as the transverse rolling prevention means constituting the wire coil fixing device of the present invention. An example of the loader rolling prevention net 3 is shown in FIG. As shown in the figure, the rolling prevention net 3 is provided with a rectangular net 5 knitted with a rope in a mocco manner and at least four corners of the rectangular net 5 via fixing ropes 6. Ring part 7 formed. FIG. 4A is an example in which the fixing rope 6 and the ring portion 7 are provided only at the four corners of the rectangular mesh portion 5, and FIG. Of the four sides of the net 5, a symmetrical position on two sides (in this example, the midpoint of each side) parallel to the longitudinal direction of the truck or trailer bed during use is also 1 fixed rope 6a pairs, 6a and the ring portion 7a, an example in which a 7a.

Of the ropes 8 constituting the net part 5 (hereinafter referred to as “net part forming ropes”), the net forming rope 8 is connected to the ring part 7 via the fixing rope 6 and used. The net forming rope 8a, which is sometimes oriented in the width direction of the loading platform, and the fixing rope 6 connected thereto are integrated, and this integrated one is thicker than the net forming rope 8b in other parts. It is preferable to do this. In this way, by thickening only the rope (8a + 6) at the portion where the load concentrates and thinning the rope 8b at the other portion where the load is dispersed, the strength of the rolling prevention net 3 is ensured while securing the strength. The overall weight can be reduced, and both prevention of rolling of the wire coil and reduction of the work load can be realized.

  The net forming rope 8a and the fixing rope 6 connected to the net forming rope 8a and the fixing rope 6 connected to the net forming rope 8a are originally formed by one rope. Easy to do.

  In addition, the fixing rope 6 and the ring portion 7 may originally be integrally formed with a single rope, but the fixing rope 6 and the ring portion 7 are made of different ropes and connected by a satin process. You may do it. Thereby, by making it possible to replace only the ring portion 7 with the most wear and tear, the life of the rolling prevention net 3 can be extended and the cost can be reduced.

  In addition, by using natural fibers (for example, hemp) and / or synthetic fibers (for example, polypropylene, polyester, etc.) as a material for at least the net forming rope 8, as in the case of using a metal wire as the material, There is no risk of wrinkles on the surface of the wire coil, and weight reduction can be realized. Of course, natural fibers and / or synthetic fibers may be used not only for the net forming rope but also for the fixing rope 6 and the ring portion 7.

  Further, the width W of the mesh portion 5 (corresponding to the length of the side facing the width direction of the loading platform 12 when used) is 1.2D to 1.65D (D: the diameter of the wire coil 11), and further 1.3D to It is recommended to use 1.55D, especially 1.43D. Here, 1.43D is a dimension in which the upper half (1/2 of the circumference) of the wire rod coil 11 is just covered with the net 5 (D × 3.14 × 1/2 ÷ 1.1≈1. 43D: The reason for dividing by 1.1 in this calculation is that when the rolling prevention net 3 is used, the rope stitch is stretched and the width of the net portion 5 is increased by about 10%). If the width W of the mesh portion 5 is less than 1.2D, the risk of rolling the wire coil 11 is increased. On the other hand, if the width W exceeds 1.65D, the width of the mesh portion 5 is too wide at the time of use, and it is easy to sag. This is because, in addition to being unable to be firmly fixed, the area of the net portion 5 becomes too large and the weight of the rolling prevention net 3 becomes excessive, making it difficult to handle.

(Wire ring fixing method)
Next, as a vehicle on which the wire coil is placed, a plurality of wire rods vertically stacked on the cargo bed of the truck using the wire coil fixing device described above, with a typical example of a tilt-type truck having a cage at the side and rear of the cargo bed A method for fixing the coil will be described.

  (2) Next, the central portion of the wire rope 1 is hung on the rear surface upper part of the last wire coil 11a.

(3) After that, the other end portion of the wire rope 1 is hung on the hook 14b in a position symmetrical to the one hook 14a via the load clamping machine 2, and the wire rope 1 is tensioned by the load clamping machine 2. The rearmost wire coil 11a is fixed so as to be pressed toward the front diagonally lower side of the loading platform 12.

  As a result of the fixing operation using the vertical direction overturn prevention means, the plurality of wire coils 11 are pressed against the torii 15 at the foremost part of the loading platform 12 and are integrally fixed in the front-rear direction. Effectively prevented.

  Next, the following (1) to (4) are used by using a plurality (two in this example) of rolling prevention nets 3 and a plurality (five in this example) of load-clamping machines 4 which are lateral rolling prevention means. ) Fixing is performed according to the procedure of). In this example, a case will be described in which the rolling prevention net 3 is used in combination with the one illustrated in FIGS. 2A and 2B one by one.

  (1) First, as the first rolling prevention net 3, the one illustrated in FIG. 2B is used, and one of the plurality of (six in this example) ring portions 7 is on one side of the net portion 5. Two or more (three in this example) ring portions 7 to be fixed among a plurality (eight coils in this example) of wire coils 11 among a plurality of hooks 14 (in this example, 5 on the front side of the loading platform). The coil is hooked on a plurality (three in this example) of hooks 14 on one side of the wire coil 11.

  (2) Next, the net part 5 is hung on the upper part of the five-wire wire coil 11 to be fixed.

(3) Thereafter, the remaining three ring portions 7 are connected to a plurality (three in this example) on the opposite side of the five-coil wire coil 11 via each of a plurality (three in this example) of the load clamping machines 4. 5 hooks 14, and the wire coil 11 of 5 coils to be fixed is lowered by tensioning the mesh portion 5 and the fixing rope 6 by the plurality (three in this example) of the clamping machines 4. Press to fix.

  (4) Then, as the second rolling prevention net 3, the one illustrated in FIG. 2 (a) is used, and the remaining two cargo tighteners 4 are used, and the same as the above (1) to (3). By fixing the remaining three coils of the wire coil 11 on the rear side of the loading platform in the procedure, the entire wire coil is fixed.

  As a result of the fixing work using the lateral direction rolling prevention means, the rolling of the entire wire coil 11 in the lateral direction is reliably prevented.

[Modification]
In the above embodiment, a truck is exemplified as a vehicle on which a plurality of wire coils are placed. However, the present invention is naturally applicable to a trailer.

  Further, in the above embodiment, the tilt type is exemplified as the type of the truck bed, but instead of having a side at the side of the bed, a stanchion type in which a plurality of stanches are provided, and further, the bed stock is omitted. Of course, the present invention can also be applied to a ship bottom type having a recess in which the lower part of the wire coil is fitted.

  In the above embodiment, as an example in which the fixing rope 6 and the ring portion 7 are also provided on the two sides of the net portion 5 of the rolling prevention net 3, an example in which a pair is provided only at the midpoint of the two sides has been shown. However, the number of pairs of the fixing rope 6 and the ring portion 7 may be further increased according to the length of the net portion 5 or the like. However, if the number of pairs of the fixing rope 6 and the ring portion 7 is increased too much, the load of the fixing work increases, and the number of times of straddling the fixing rope 6 increases when the seat cover is attached. It is important to adjust the number of pairs of the fixing rope 6 and the ring portion 7 within a range in which the strength of the prevention net 3 can be secured. For this reason, in order to easily adjust the number of pairs of the fixing rope 6 and the ring portion 7, for example, the fixing rope 6 and the fixing rope 6 are arranged at two locations on the two sides of the net portion 5 of the rolling prevention net 3 by satama processing. It is preferable that the ring portion 7 be in a state where it can be attached.

  Moreover, in the said embodiment, although the shape of the opening of the net | network part 5 of the rolling prevention net | network 3 was made into the rectangle, it is not limited to this, For example, it is good also as a triangle and a hexagon.

  Moreover, in the said embodiment, although the example which fixes a some wire rod coil with the two rolling prevention nets 3 was shown, it is not limited to this, You may fix only by 1 piece, 3 You may fix using more than one sheet. If the number of rolling prevention nets 3 is reduced, the number of work is reduced, but the weight per piece increases. Conversely, if the number is increased, the weight per piece is reduced, but the number of work increases. Thus, adjustment should be made so that the workload is reduced most.

  Moreover, in the said embodiment, when using several rolling prevention net | network 3, the example used combining a thing of different length was shown, However, The thing of the same length may be used and the wire rod coil to load is used. The combination can be appropriately changed according to the total number, the winding thickness of the wire coil, and the like.
