Description

  The present invention relates to a heavy load placing device, and more particularly to a heavy load placing device for placing a heavy load to be loaded into a container.

  In order to load and carry heavy objects in a container, various measures are taken because inertial force and impact force during transportation cannot be ignored.

  FIG. 10 is a view showing the external shape of a general dry container disclosed in Patent Document 1, and FIG. 11 is an enlarged cross-sectional view of the XI-XI line shown in FIG.

  As shown in FIG. 10, since two coils are loaded in the container 53 like the coils 4 a and 4 b, a large space is generated in the container 53. Then, the proposal which prevents the movement and fall of a steel plate coil by an inertia force or an impact force by installing wood in the space of the coils 4a and 4b mounted on the container pallet and the container side wall and the end wall is proposed. .

  Next, referring to FIG. 11, a container pallet 50 made of a steel material arranged in a planer girder shape is arranged on the bottom plate 34 of the container 53. Further, in order to prevent the container 53 from moving in the direction of the side plates 31 a and 31 b, fixing materials 55 a and 55 b are disposed between the container 53 and the container pallet 50.

  A floor plate 51 is disposed on the container pallet 50, and the coil 4a is disposed on the floor plate 51 via rotation stoppers 52a to 52d for preventing the movement of the coil 4a. Further, fixing members 57a to 57d are provided at four corners in the plan view of the container pallet, and the coils 4a are used for the container by passing the wires 54a and 54b through the core of the coil 4a and connecting them to the respective fixing members. It is fixed to the pallet 50.

  FIG. 12 is a schematic view showing a fall state of the heavy article placing device shown in FIG.

  Referring to the figure, when a horizontal force F acts on the center of gravity G of the container pallet 50 with the coil 4 placed thereon due to an impact during transportation or the like, the container pallet 50 is fixed by a fixing member 55. A rotational moment around the point P is applied. At this time, if the counterclockwise moment in the figure becomes larger than the counterclockwise moment, the container pallet 50 rotates counterclockwise and falls.

In order to prevent such a fall, the counterclockwise moment must be smaller than the counterclockwise moment. That is, the weight of the container pallet 50 with the coil 4 placed thereon is W, the vertical distance from the horizontal plane passing through the point P to the center of gravity G is H, and the horizontal distance from the vertical plane passing through the point P to the center of gravity G is L. Then
F ・ H <W ・ L (1)
Must be. Here, assuming that the force F is N times the weight W, that is, F = N · W,
N ・ W ・ H <W ・ L ・ ・ ・ ・ ・ ・ ・ ・ （2）
And calculating equation (2),
N <L / H (3)
Thus, if the condition of the expression (3) is satisfied, there is no possibility that the container pallet 50 falls.
JP 2001-315882 A

  In the conventional heavy load placing device as described above, the condition of the above-described formula (3) must be satisfied in order to prevent the container pallet with the heavy load placed thereon from being overturned. In order to satisfy this condition, L in equation (3) may be increased if H is constant. In other words, a method of lengthening the container pallet in the direction in which the force acts is conceivable, but there are limitations due to the size and cost of the container. Therefore, when N becomes an unexpected size, the above condition is not satisfied, and there is a possibility that a heavy object falls over with the container pallet.

  According to a third aspect of the present invention, in the configuration of the second aspect of the invention, the portion of the first movement blocking member that engages with the first steel pipe has a first inclined plane that rises downstream, and the second movement The portion of the blocking member that engages with the second steel pipe has a first inclined plane that rises upstream.

  If comprised in this way, while the impact at the time of engagement will be relieved, an engagement position will raise according to an impact.

  According to a fourth aspect of the present invention, in the configuration of the second aspect of the present invention, the portion of the first movement blocking member that engages the first steel pipe has a first inclined curved surface whose inclination angle increases further toward the downstream side. The part which engages with the 2nd steel pipe of a 2nd movement prevention member has a 2nd inclined curved surface where an inclination angle rises more as it goes upstream.

  If comprised in this way, the reaction force from a movement prevention member will increase as an engagement position goes up.

  According to a fifth aspect of the present invention, in the configuration of the second aspect of the present invention, the placing means supports the first steel pipe and the second steel pipe and is arranged in parallel in a predetermined direction. The pair of supporting members includes a pair of guides fixed to the floor surface in a state arranged in parallel to the predetermined direction so as to guide the movement of the supporting member to the upstream side and the downstream side in the predetermined direction. Each of the first movement blocking member and the second movement blocking member is provided in a pair and is supported by each of the guide members.

  If comprised in this way, a movement of a mounting means will be guided to a guide member. Moreover, the movement of the steel pipe is blocked at two places.

  As described above, according to the first aspect of the present invention, when a force in a predetermined direction is applied to the mounting means, a rotational moment that presses the mounting means against the floor surface is generated, so that the mounting means does not fall down. .

  In addition to the effect of the invention described in claim 1, the invention described in claim 2 is prevented from moving upstream of the moving direction regardless of the moving direction of the mounting means, so that the mounting state is more stable. .

  FIG. 1 is a schematic perspective view of a heavy article placing apparatus according to a first embodiment of the present invention, FIG. 2 is an enlarged sectional view taken along line II-II shown in FIG. 1, and FIG. FIG. 4 is an enlarged cross-sectional view taken along line III-III, and FIG. 4 is an enlarged cross-sectional view taken along line IV-IV shown in FIG.

  With reference to these drawings, the coil 4 which is a heavy load is loaded in the container 53 via the heavy load placing device 10. This heavy article placing apparatus 10 includes a container pallet 20 that is a placing means for placing the coil 4, and a fixing jig 30 that is a movement preventing means that engages with the container pallet 20 and prevents its movement. It is composed of Details of these will be described below.

  The container pallet 20 is spaced from the supporting members 7a and 7b made of H-shaped steel disposed on the floor surface 33 in parallel with the longitudinal direction (predetermined direction) of the container 53 with a predetermined interval in the short direction perpendicular to the longitudinal direction. And it is mainly comprised from a pair of 1st steel pipe 8 and 2nd steel pipe 9 arrange | positioned on the supporting members 7a and 7b horizontally. In addition, the 1st steel pipe 8 and the 2nd steel pipe 9 are installed on the bases 14a-14d provided in each one of the supporting members 7a and 7b.

  The side wall of the cylindrical coil 4 is supported by the first steel pipe 8 and the second steel pipe 9 between the first steel pipe 8 and the second steel pipe 9, and the first and second steel pipes 8 and 2 are supported by belts 12a and 12b. It is integrated with the steel pipe 9.

  Since the container pallet 20 is configured as described above, the container pallet 20 can move upstream and downstream in the longitudinal direction of the container 53.

  Next, the fixing jig 30 that prevents the container pallet 20 from moving will be described.

  The fixing jig 30 is a pair of guides made of H-shaped steel disposed on the floor surface 33 in parallel to the inner sides of the support members 7a and 7b so as to guide the movement of the container pallet 20 in the longitudinal direction. Members 22a and 22b are provided. The height of each of the guide members 22a and 22b is set so as to have a slight gap with the lower ends of the first steel pipe 8 and the second steel pipe 9 so as not to hinder the movement of the container pallet 20 in the longitudinal direction. Yes. Further, the guide members 22a and 22b are prevented from moving in the longitudinal direction by fixing members 11a to 11d which are installed at both ends and fixed to the floor surface 33. When the container pallet 20 moves upstream and downstream in the longitudinal direction, the movement is guided along the guide members 22a and 22b, so the container pallet 20 moves carelessly in a direction other than the longitudinal direction. There is no risk of doing so. Therefore, the reliability of the mounting state of the coil 4 is improved.

  Further, a pair of first movement blocking members 25a and 25b, which are respectively arranged downstream of the first steel pipe 8 on the support members 7a and 7b, and an upstream side of the second steel pipe 9 on the support members 7a and 7b, respectively. A pair of second movement blocking members 26a and 26b are provided.

  The first movement blocking members 25a and 25b are formed in a wedge shape having first inclined flat surfaces 35a and 35b that rise downstream in the cross-sectional state in the short direction. The lower end of each of the first inclined planes 35 a and 35 b is set to be substantially the same height as the lower end of the first steel pipe 8. The second movement blocking members 26a and 26b are formed in a wedge shape having second inclined flat surfaces 36a and 36b that rise upstream in the cross-sectional state in the short direction. The lower end of each of the second inclined planes 36 a and 36 b is set to be substantially the same height as the lower end of the second steel pipe 9. Therefore, as the container pallet 20 moves downstream in the longitudinal direction, the first steel pipe 8 and each of the first inclined flat surfaces 35a and 35b of the first movement blocking members 25a and 25b are engaged smoothly. Stop movement. Further, as the container pallet 20 moves to the upstream side in the longitudinal direction, the second steel pipe 9 and each of the second inclined flat surfaces 36a, 36b of the second movement blocking members 26a, 26b smoothly engage with each other. Stop movement. These effects will be described later.

  Next, the reason why the heavy article placing apparatus 10 according to this embodiment does not fall will be described.

  FIG. 5 is a schematic diagram showing the relationship of forces acting when the heavy article placement device shown in FIG. 1 moves.

  Referring to the figure, when the force F in the horizontal direction acts on the center of gravity G of the placing means with the coil 4 placed on the left side in the figure due to impact or the like during container transportation, the placing means moves in the longitudinal direction of the container. Since it is movable upward, the coil 4 moves to the left in the figure.

  As described above, since the coil 4 is integrated with the first steel pipe 8 and the second steel pipe 9, as the coil 4 moves in the left direction in the figure, the first steel pipe 8 and the second steel pipe 9 are also on the left in the figure. Will move in the direction.

  Then, the 1st steel pipe 8 engages with the 1st movement prevention member 25a. In this state, the first steel pipe 8 is simultaneously engaged with the first movement blocking member 25b (not shown), but the effect is the same, so the description is omitted. At this time, since the first movement preventing member 25a includes the first inclined plane 35a, the first steel pipe according to the magnitude of the force F while receiving the reaction force and the frictional resistance from the first inclined plane 35a. The position of the contact point P between 8 and the first movement blocking member 25a is raised. Along with this, the position of the center of gravity G also rises. Thus, since the energy of force F is used for the energy which raises the position of the gravity center G, the impact at the time of engagement with the 1st steel pipe 8 and the 1st movement prevention member 25a is relieved. Therefore, damage to the coil 4 is reduced and the energy of the force F is efficiently absorbed.

  In addition, as described above, the first movement blocking member 25a attempts to block the movement of the first steel pipe 8 in the left direction in the drawing at the contact point P. Therefore, a rotational moment M is generated by the force F and the weight W of the mounting means with the coil 4 mounted, with the contact point P as the center. Since the contact P is always located on the right side of the drawing with respect to the vertical line of the center of gravity G, the force F and the weight W try to rotate the mounting means counterclockwise in the drawing. That is, the rotational moment M acts only to press the mounting means against the floor surface 33. Therefore, if the magnitude of the rotational moment M is in a range that does not exceed the strength of the floor surface 33 of the container, there is no possibility that the heavy article placement device on which the coil 4 is placed rotates. This range will be described below.

  A plurality of cross members 15 for reinforcing the floor surface 33 are installed below the floor surface 33 of the container. When the mounting means is pressed against the floor surface 33 by the rotational moment M, a reaction force R is generated in the cross member 15. When the rotational moment in the opposite direction based on the reaction force R is larger than the rotational moment M, it can be said that the above range is satisfied.

Here, the vertical distance from the horizontal plane passing through the contact point P to the center of gravity G is H, and the horizontal distance from the vertical plane passing through the contact point P to the center of gravity G is L. Furthermore, when the distance from the vertical line of the contact point P to each of the cross members on the left side of the drawing is L1 to L4, the formula satisfying the above range is:
F ・ H + W ・ L <R (L1 + L2 + L3 + L4) (4)
It is. Assuming that the force F is N times the weight W, that is, F = N · W,
W (N · H + L) <R (L1 + L2 + L3 + L4) (5)
And calculating equation (5),
W <R (L1 + L2 + L3 + L4) / (N · H + L) (6)
It becomes. If the number of cross members is i,
W <R · ΣLi / (N · H + L) (7)
That is, if the condition of the expression (7) is satisfied, the heavy article placing device on which the coil 4 is placed has no fear of falling due to the collapse of the floor surface 33 of the container.

  The above conditions can be similarly applied to the second steel pipe 9 and the second movement blocking members 26a and 26b. Therefore, regardless of the moving direction of the container of the mounting means in the longitudinal direction, it always engages on the upstream side with respect to the moving direction to prevent the movement. Therefore, the mounting state of the coil 4 is stabilized.

  Further, the first steel pipe 8 is engaged at two positions of the first movement blocking members 25a and 25b, the movement is blocked, and the second steel pipe 9 is engaged at two positions of the second movement blocking members 26a and 26b, That movement is blocked. For example, if the first steel pipe 8 is engaged only by the first movement prevention member 25a and tries to prevent the movement, the first steel pipe 8 may be inclined in plan view. Therefore, the movement blocking state is stabilized by engaging at two places as described above.

  Next, the inclined plane in the movement blocking member will be described.

  FIG. 6 is a schematic diagram showing a force relationship in a state where the steel pipe and the movement preventing member are engaged.

  Referring to the figure, it is assumed that a horizontal force P is applied to the first steel pipe 8 in the left direction of the figure, and the first movement blocking member 25 having the inclination angle θ and the first steel pipe 8 are engaged. In this case, the weight W of the mounting means with the coil mounted on the operating point is applied to the first movement preventing member 25 in the vertical direction. On the other hand, a reaction force R perpendicular to the inclined surface with respect to the action point is applied from the first movement blocking member 25 to the first steel pipe 8. The frictional force F generated by the dynamic friction coefficient μ defined by the first inclined plane 35 of the first movement blocking member 25 and the first steel pipe 8 is first along the first inclined plane 35 of the first movement blocking member 25. It will be added to the steel pipe 8.

  FIG. 7 is a vector diagram showing the balance of forces in the state shown in FIG.

Referring to the drawing, when various forces are balanced, weight W, force P, reaction force R and friction force F form a closed loop as shown in the figure from the balance of forces. At this time,
F = R · μ
Because
μ = tanφ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ （8）
It becomes. Therefore,
P = W · tan (θ + φ) (9)
It becomes. Here, assuming that the force P is N times the weight W, that is, P = N · W,
N · W = W · tan (θ + φ) (10)
It becomes. When formula (10) is calculated,
θ + φ = tan ⁻¹ N (11)
It becomes. Here, when equation (8) is transformed,
φ = tan ⁻¹ μ (12)
When substituting equation (12) into equation (11),
θ = tan ⁻¹ N-tan ⁻¹ μ (13)
It becomes.

The inclination angle θ calculated by the equation (13) is in a state where various forces are balanced. That is,
θ ≧ tan ⁻¹ N-tan ⁻¹ μ (14)
If so, the first movement preventing member 25 having the inclination angle θ according to the equation (9) prevents the movement of the first steel pipe 8 in the left direction in the drawing, that is, the movement of the mounting means on which the coil is mounted. It will be possible. When the force P exceeding the balance works for a certain period of time, the generated energy is absorbed by the frictional force F and the increase in the position of the center of gravity G.

  FIG. 8 is a cross-sectional view of a heavy article placing apparatus according to the second embodiment of the present invention, and corresponds to FIG. 4 of the first embodiment.

  Since the description is basically the same as that of the first embodiment, the difference will be mainly described.

  Referring to the drawing, in this embodiment, the shapes of first movement blocking members 25a and 25b (not shown) and second movement blocking members 26a and 26b (not shown) are different. That is, the first movement blocking members 25a and 25b (not shown) are provided with first inclined curved surfaces 18a and 18b (not shown) whose inclination angle increases further toward the left side of the drawing. At the same time, the second movement blocking members 26a and 26b (not shown) are provided with second inclined curved surfaces 19a and 19b (not shown) whose inclination angle increases further toward the right side of the figure.

  The effect of the movement blocking member having such an inclined curved surface will be described below.

  FIG. 9 is a schematic view showing the shape of the movement blocking member shown in FIG.

  Referring to the figure, the first movement blocking member 25 includes an inclined curved surface 18 whose inclination angle increases as it goes to the left side of the figure. A method for setting the inclined curved surface 18 will be described.

  The inclination curve 18 is set based on the above equation (13). That is, each inclination angle θ is set for various horizontal forces P such that the magnitude of the force becomes P1 <P2 <P3 <Pk. The inclination angle corresponding to the horizontal force P 1 is calculated as θ 1, the inclination angle θ 2 is calculated as the horizontal force P 2, and the inclination angle θ k is calculated as the horizontal force Pk, which corresponds to the portion of the first movement preventing member 25 engaged with the steel pipe. Then, as the horizontal force P increases, the inclination angle θ increases, so that the inclination angle gradually increases as shown in the figure. An inclined curved surface 18 having a radius X that approximates this surface and having an arc shape when viewed from the side is set.

  The first movement preventing member 25 having the inclined curved surface 18 set in this way increases the horizontal force P to be balanced as apparent from the equation (9) as the engagement position with the steel pipe increases. . That is, since the rate at which the position of the center of gravity G rises gradually increases, the amount of absorbed energy gradually increases from the beginning of engagement, and the reaction force from the movement blocking member also gradually increases. Therefore, it is possible to alleviate an impact caused by a sudden collision at the time of engagement, and it is possible to further stabilize the movement blocking state of the placing means on which the heavy object is placed.
