Patent Document 1: Japanese Patent Publication No. 2015-107665

For example, a metal material processed by a machine tool or a workpiece after processing is relatively heavy, and if loading and unloading to and from a truck is frequently required, the number of processes is also increased, and the burden on the operator is high.

Therefore, it is necessary to reduce the loading and unloading of goods to and from the truck as much as possible. As one method, a method of storing an article on a bogie is possible after loading the article on a bogie.

However, conventional trucks are easily moved when an external force is applied, and therefore it is necessary to provide a stopper or the like. In addition, in the conventional bogie, there is a problem that the handle is obstructed when arranging a large number of bogies because the operator has a handle for manipulating.

The present invention has been exemplified in view of the above points, and one of its objectives is to provide a truck that is suitable for storage and preservation of the load, and also easy to organize, as well as the movement of the load.

EMBODIMENT OF THE INVENTION Hereinafter, embodiment of this invention is described with reference to drawings.

1A to 3 show the structure of a bogie according to an embodiment of the present invention. In addition, in the figure, L1 and L2 represent the longitudinal direction of the bogie 1 in the horizontal plane parallel to the floor surface FL, and M1 and M2 are in the longitudinal direction of the longitudinal directions L1 and L2 of the bogie 1 in the horizontal plane. Orthogonal transverse direction.

The bogie 1 is composed of a bogie body 10 and an operation tool 30 that is detachably connected to the bogie body 10.

As shown in Fig. 2 and the like, the bogie main body 10 includes two wheels provided at the L1 side ends in the longitudinal direction of the undercarriage 11 having a rectangular outer shape and the underside 11b of the undercarriage 11. 13A, 13B), two support portions 12A, 12B provided at the end portion on the L2 side in the longitudinal direction of the lower surface 11b of the carrier portion 11, and the connection portion 15.

Although the article 11 to be transported is loaded on the pallet 11, it may be a plate formed of a metal material or the like, or a combination of frame members. Further, in addition to the plate or the frame, it is also possible to employ a metal net basket as a carrier, and a wheel (caster) provided on the lower surface. In addition to heavy objects, it is possible to transport and retain large-capacity articles.

The wheels 13A and 13B are provided at both ends of the transverse directions M1 and M2 of the lower surface 11b of the carriage 11, and are rotatable about the axis K1, and the directions of the wheels 13A and 13B are It is fixed.

The support portions 12A, 12B are formed of steel or the like, and are end portions opposite to the wheels 13A, 13B of the lower surface 11b of the pallet 11, and are provided at both ends of the transverse directions M1, M2. . In the support portions 12A and 12B, the bottom surface 12b contacts the bottom surface FL. In a state where the support portions 12A and 12B contact the bottom surface FL, the two support portions 12A and 12B and the two wheels 13A and 13B cooperate to hold the carrier portion 11 almost horizontally, The load from the pallet 11 is supported. When the lower surface 12b of the support portions 12A and 12B is in contact with the floor surface FL, the larger the weight of the object loaded on the pallet 11, the lower the frictional force between the lower surface 12b and the lower surface FL. It becomes large, and it becomes difficult for the bogie body 10 to move on the bottom surface FL.

The to-be-connected part 15 is installed at an approximately intermediate position between the two support parts 12A, 12B, and is made of a cylindrical member made of metal, having a through-hole 15a, and having an annular bottom surface 15b It engages with the connection part 33 of the operation tool 30 mentioned later. The connection portion 15 is fixed to the lower surface 11b of the carrier 11 by welding.

As shown in FIG. 3, the operation tool 30 has the operation pole part 31 extended linearly, and the lifter part 32 provided in the lower end side of the operation pole part 31. As shown in FIG.

At the upper end portion of the operation pole portion 31, a handle portion 31a for gripping by an operator operating the trolley 1 is provided to extend horizontally in a direction orthogonal to the operation pole portion 31.

The lifter part 32 is provided at the lower end portion of the operation pole part 31, and the connection part 33 formed at the lower end part of the operation pole part 31, and the axis of the operation pole part 31 from the connection part 33 The wheels 35A, 35B rotatably supported on the axle 37 extending in the direction of the axis T1 orthogonal to S1, and the two arm portions 36A, 36B formed protruding from the connecting portion 33 (hereinafter, the arm portion) (36).

On the upper surface 33a of the connecting portion 33, a cylindrical projection 34 is provided. The protruding portion 34 is formed so as to be inserted into the through hole 15a of the cylindrical member constituting the connected portion 15 of the bogie body 10.

Since the steering wheels 35A and 35B are rotatably installed in the operation pole 31 of the operation tool 30, the standing state cannot be maintained without support. However, as shown in Fig. 4 and the like, the arm portion 36 contacts the bottom surface FL to regulate the tilt of the operation pole 31, so that the operation pole 31 is maintained in a slightly inclined state.

Next, the operation of connecting the bogie body 10 and the operation tool 30 will be described.

In order to connect the bogie body 10 and the operation tool 30, first, as shown in FIG. 4, the connection portion 33 of the lifter portion 32 of the operation tool 30 is a connection portion of the loader portion 10 The posture (inclination) of the operation pole part 31 and the position of the operation tool 30 are adjusted so that it is located below (15).

Specifically, as shown in Fig. 5A, the operation tool 30 is approached to the pedestal portion 11 provided on the bottom surface FL. At this time, the inclination of the operation pole 31 is adjusted so that the protrusion 34 of the connecting portion 33 is located below the lower surface 15 of the engaging portion 15. In addition, as shown in Fig. 4, in the state where the operation pole 31 is supported by the wheel 35 and the arm 36, the protrusion 34 of the connecting portion 33 is the lower end of the engaging portion 15 It is designed to be disposed below the surface 15.

Next, as shown in Fig. 5B, the operation tool 30 is brought close to the bogie main body 10, and the protrusion 34 of the connecting portion 33 is directly in the through hole 15a of the engaging portion 15. Operate to come down. Then, as shown in Fig. 5C, the operating pole 31 is inclined in the tilting direction A1. The tilting direction A1 is opposite to the direction in which the operating pole 31 shown in Figs. 4 and 5A is inclined. When the operating pole 31 is inclined in the tilting direction A1, the position of the protrusion 34 of the connecting portion 33 moves upwards, and a part of the protrusion 34 penetrates through the hole 15a of the engagement portion 15 Pushing in, the protrusion 34 contacts the inner circumferential surface of the through hole 15a, and the upper surface 33a of the connecting portion 33 contacts the lower surface 15b of the engaging portion 15. In other words, the connecting portion 33 is caught by the engaging portion 15.

When the operating pole 31 is inclined in the tilting direction A1, as shown in Fig. 5D, the tilting moment acting on the operating pole portion 31 by the operator's operation makes the wheel 37 a point, and the connection portion 33 The upper surface (33a) acts as a force to push up the lower surface (15b) of the connection portion 15 is caught upward. At the same time, the wheel 35 as a point moves in the direction B1 toward the downward position of the through hole 15a. Due to this "knuckle action", the lower surface 12b of the support portion 12 of the bogie body 10 rises from the bottom surface FL, and is between the bottom surface FL and the lower surface 12b of the support portion 12. A slight gap is formed.

If the operation pole 31 is further inclined in the tilting direction A1, as shown in Fig. 5E, the wheel wheel 35 moves closer to the lower position of the through hole 15a, and the load bearing portion supported by the wheel wheel 35 ( The load of 11) increases. The moment in the opposite direction to the tilt direction A1 acting on the operation pole 31 also rapidly decreases, and the operator hardly feels a reaction force from the operation pole 31.

As shown in FIG. 5F, when the wheel 35 reaches the lower position of the through hole 15a, the lower surface 15b of the connection portion 15 is in full contact with the upper surface 33a of the connection portion 33 Then, the wheel 35 supports the load of the carrier 11 in cooperation with the wheel 13. Accordingly, a moment in the opposite direction to the tilt direction A1 does not act on the operation pole 31. At this time, the arm portion 26 contacts the bottom surface 11b of the carrier portion 11, and the new inclination of the operation pole 31 to the tilting direction A1 is restricted. As a result, the cart 1 is in the state shown in Fig. 1A. In this state, the connecting portion 33 is in a rotatable state with respect to the connected portion 15. In addition, a slight gap is formed between the bottom surface 12b of the support portion 12 and the bottom surface FL, and the pedestal portion 11 is also slightly inclined, but this inclination is in a range that does not affect the loaded load. All.

In the bogie 1 in which the bogie main body 10 and the operation tool 30 are connected to each other, as shown in Fig. 6A, the operating pole 31 is maintained in the direction along the longitudinal direction L1, L2 of the bogie body 10 In doing so, you can advance or retreat directly by pushing or pulling the operation tool.

In order to change the moving direction of the bogie 1, that is, in order to change the moving direction of the bogie to the right or left direction, as shown in Fig. 6B, the operating pole 31 is moved with respect to the longitudinal directions L1 and L2. Bend to one side. Since the connecting portion 33 is rotatable relative to the connected portion 15, it is possible to simply change the moving direction.

In order to separate the bogie main body 10 and the operation tool 30, it is sufficient to operate the operation tool 30 in the reverse order to FIGS. 5A to 5F.

According to the present embodiment, it is more preferable to use a net basket as a baggage portion, particularly with respect to baggage collapse.

Although the operation tool 30 may be prepared for each of the plurality of bogie bodies 10, it is also possible to share one operation tool 30 for the plurality of bogie bodies 10.

In the above embodiment, the case where the connection portion 15 is formed of a cylindrical member and the connection portion 33 is formed of a cylindrical member is illustrated, but the present invention is not limited to this, and the connection portion 33 side is cylindrical. It may be formed of a member, and the to-be-connected portion 15 may be formed as a protruding member, and the structure of the to-be-connected portion and the connected portion can be changed in various ways.

In the above embodiment, the case where the supporting portions 12A, 12B are provided is illustrated, but the present invention is not limited to this, and the place, shape, and number can be appropriately changed.

In the above-described embodiment, various forms have been illustrated with respect to the shape of the pallet, but it is not limited to these, and can be configured in accordance with all loads related to material transportation of factories such as transportation of round bar steel.
