The carriage 1 includes a carriage main body 10 and a manipulation tool 30 detachably connected to the carriage main body 10.
As shown in fig. 2 and the like, the truck main body 10 includes a cargo bed portion 11 having a rectangular outer shape, two wheels 13A, 13B provided at an end portion on the L1 side in the longitudinal direction of the lower surface 11B of the cargo bed portion 11, two support portions 12A, 12B provided at an end portion on the L2 side in the longitudinal direction of the lower surface 11B of the cargo bed portion 11, and a coupled portion 15.
The platform part 11 is loaded with an article to be conveyed, and the platform part 11 may be a plate material made of a metal material or the like, or may be a structure in which frame members are combined. In addition to the plate material and the frame, a metal mesh basket may be used as the cargo bed portion, and a structure in which wheels (caster wheels) are provided on the lower surface thereof may be used. Not only heavy objects but also large-capacity articles can be transported and held.
The wheels 13A and 13B are provided at the end of the lower surface 11B of the cargo bed 11 in the lateral direction M1, and the wheels 13B are provided at the end of the lower surface 11B of the cargo bed 11 in the lateral direction M2, respectively, and the wheels 13A and 13B are rotatable about the axis K1, and the directions of the wheels 13A and 13B are fixed.
The support portion 12A is formed of a steel material or the like, and is provided at an end portion of the lower surface 11B of the table portion 11 on the side opposite to the wheel 13A side and is an end portion of the lateral direction M1, and the support portion 112B is formed of a steel material or the like, and is provided at an end portion of the lower surface 11B of the table portion 11 on the side opposite to the wheel 13B side and is an end portion of the lateral direction M2, lower end surfaces 12B of the support portions 12A, 12B are in contact with the floor surface F L, in a state where the support portions 12A, 12B are in contact with the floor surface F L, the two support portions 12A, 12B and the two wheels 13A, 13B cooperatively hold the table portion 11 substantially horizontally and support a load from the table portion 11, and the frictional force between the lower end surface 12B and the floor surface F L is increased as the weight of an object loaded on the table portion 11 is increased by the lower end surfaces 12B of the support portions 12A, 12B being in contact with the floor surface F L.
The connected portion 15 is provided at a substantially intermediate position between the two support portions 12A and 12B, is formed of a metal cylindrical member, has a through hole 15a, and has an annular lower end surface 15B engaged with a connecting portion 33 of an operating tool 30 described later. The coupled portion 15 is fixed to the lower surface 11b of the cargo bed portion 11 by welding.
As shown in fig. 3, the operation tool 30 includes an operation rod portion 31 extending linearly and a jack portion 32 provided on a lower end portion side of the operation rod portion 31.
A grip portion 31a to be gripped by an operator operating the cart 1 is provided at an upper end portion of the operation lever portion 31 so as to extend horizontally in a direction orthogonal to the operation lever portion 31.
The jack portion 32 is provided at the lower end portion of the operation lever portion 31, and includes: a connection portion 33 formed at a lower end portion of the lever portion 31; wheels 35A, 35B, the wheels 35A, 35B being rotatably supported by an axle 37, the axle 37 extending from the connecting portion 33 in the direction of an axis T1 substantially orthogonal to the axis S1 of the lever portion 31; and two arm portions 36A and 36B (hereinafter also referred to as arm portions 36) formed to protrude from the coupling portion 33.
A columnar protrusion 34 is provided on the upper end surface 33a of the coupling portion 33. The protruding portion 34 is formed to be insertable into the through hole 15a of the cylindrical member constituting the connected portion 15 of the carriage body 10.
Since the wheels 35A and 35B are provided to be rotatable, the operating lever 31 of the operating tool 30 cannot be maintained in the standing state unless supported, however, as shown in fig. 4 and the like, the arm portion 36 is in contact with the floor surface F L to restrict the tilting of the operating lever 31, and the operating lever 31 can be maintained in the standing state in a slightly tilted state.
Next, a coupling operation between the carriage body 10 and the operation tool 30 will be described.
To couple the carriage body 10 and the operation tool 30, first, as shown in fig. 4, the posture (inclination) of the operation lever portion 31 and the position of the operation tool 30 are adjusted so that the coupling portion 33 of the hoisting portion 32 of the operation tool 30 is positioned below the coupled portion 15 of the table portion 10.
Specifically, as shown in fig. 5A, the operating tool 30 is brought close to the platform part 11 provided on the floor surface F L, and at this time, the inclination of the operating lever 31 is adjusted so that the protruding part 34 of the connecting part 33 is positioned below the lower end surface 15 of the engaged part 15, and as shown in fig. 4, the protruding part 34 of the connecting part 33 is designed to be positioned below the lower end surface 15 of the engaged part 15 in a state where the operating lever 31 is supported by the wheel 35 and the arm 36.
Next, as shown in fig. 5B, the operation tool 30 is moved closer to the carriage body 10, and the protrusion 34 of the coupling portion 33 is operated to come directly below the through hole 15a of the engaged portion 15. Then, as shown in fig. 5C, the operation lever 31 is tilted in the tilting direction a 1. The tilting direction a1 is a direction opposite to the direction of tilting of the operation lever 31 shown in fig. 4 and 5A. When the operating lever 31 is tilted in the tilting direction a1, the position of the protruding portion 34 of the connecting portion 33 moves upward, a part of the protruding portion 34 enters the through hole 15a of the engaged portion 15, the protruding portion 34 abuts against the inner peripheral surface of the through hole 15a, and the upper end surface 33a of the connecting portion 33 abuts against the lower end surface 15b of the engaged portion 15. That is, the connecting portion 33 is locked to the engaged portion 15.
When the operation lever 31 is tilted in the tilting direction a1, as shown in fig. 5D, the tilting moment acting on the operation lever portion 31 by the operation of the operator acts as a force that pushes up the lower end surface 15B of the coupled portion 15, which is locked to the upper end surface 33a of the coupling portion 33, upward with the wheel 37 as a fulcrum, and at the same time, the wheel 35 as a fulcrum moves in the direction B1 toward the lower position of the through hole 15a, and by this "leverage effect", the lower end surface 12B of the support portion 12 of the carriage body 10 is lifted from the floor surface F L, and a slight gap is formed between the floor surface F L and the lower end surface 12B of the support portion 12.
When the operating lever 31 is further tilted in the tilting direction a1, as shown in fig. 5E, the wheel 35 further approaches the lower position of the through hole 15a, and the load on the platform portion 11 supported by the wheel 35 increases. The moment acting on the operation lever 31 in the direction opposite to the tilting direction a1 also sharply decreases, and the operator hardly feels a reaction force from the operation lever 31.
As shown in fig. 5F, when the wheel 35 reaches the position below the through hole 15a, the lower end surface 15b of the coupled portion 15 entirely contacts the upper end surface 33a of the coupling portion 33, and the wheel 35 supports the load of the cargo bed portion 11 in cooperation with the wheel 13, and thereby, the moment in the direction opposite to the tilting direction a1 no longer acts on the operation lever 31, and at this time, the arm portion 26 abuts on the bottom surface 11b of the cargo bed portion 11, and the further tilting of the operation lever 31 in the tilting direction a1 is restricted, and as a result, the truck 1 is in the state shown in fig. 1A, in which the coupling portion 33 is rotatable with respect to the coupled portion 15, and a slight gap is formed between the lower end surface 12b of the support portion 12 and the ground surface F L, and the cargo bed portion 11 is slightly tilted, but the tilting is within a range that does not affect the loaded load.
In the carriage 1 in which the carriage body 10 and the operation tool 30 are coupled to each other, as shown in fig. 6A, the carriage 1 can be moved forward or backward straight by pushing or pulling the operation tool while maintaining the operation lever 31 in a direction along the longitudinal direction L1, L2 of the carriage body 10.
When changing the moving direction of the carriage 1, that is, when changing the moving direction of the carriage to the right or left, as shown in fig. 6B, the operating lever 31 is bent in one direction with respect to the longitudinal directions L1, L2, and the connecting portion 33 can rotate with respect to the connected portion 15, so that the moving direction can be changed easily.
When the carriage body 10 and the operation tool 30 are separated from each other, the operation tool 30 may be operated in a reverse procedure to that of fig. 5A to 5F.
According to the present embodiment, particularly, regarding the scattering of the cargo, it is more preferable to use a net basket as the cargo bed portion.
The operation tools 30 may be prepared for each of the plurality of carriage bodies 10, but one operation tool 30 may be shared by a plurality of carriage bodies 10.
In the above-described embodiment, the case where the connected portion 15 is formed by the cylindrical member and the connecting portion 33 is formed by the cylindrical member has been exemplified, but the present invention is not limited to this, and the connected portion 33 side may be formed by the cylindrical member and the connected portion 15 side may be formed by the protruding member, and the structures of the connected portion and the connecting portion may be variously changed.
In the above embodiment, the case where the support portions 12A and 12B are provided has been exemplified, but the present invention is not limited thereto, and the location, shape, and number can be changed as appropriate.
In the above embodiment, various forms have been exemplified as the form of the pallet part, but the present invention is not limited to this, and the pallet part can be configured by all the loads related to material conveyance in a factory, such as conveyance of round bar steel.
