Description

[0002] Multi heaping and carrying carts [0003]

More particularly, the present invention relates to a stacked truck for box-type cargo transportation, in which a plurality of trucks are stably stacked while a box mounted on the truck is stably fixed and storage efficiency is improved.

BACKGROUND ART Generally, trucks are mainly used as transportation means for transferring compact cargo to human power at work sites such as various factories and construction sites.

Such bogies are provided in various forms such as a cart, a cart, a hand cart, and a carrier. In particular, a quadrangular carriage in which wheels (casters) are installed at four corners of the lower part of a rectangular panel is widely used.

FIGS. 1A and 1B are photographs showing the state of use of a conventional square bogie.

In detail, the conventional rectangular carriage is carried with the cargo loading box just mounted on the upper surface of the panel, as in Fig. As a result, there is a problem that the bottom surface of the work site is not flat or the cargo loading box can not be fixed when the direction is changed. In addition, although some ropes or wires may be used to fix the cargo loading box, it is troublesome to tie or untie the cargo loading box.

In the case of a bogie which has been used, the used bogie racks are stacked in a multi-stage manner for the efficiency of the storage space, as shown in Fig. 1B, .

However, since the casters are flexibly rotated on the upper side of the panel, there is a problem that it is difficult to adjust the center of gravity when stacking. Therefore, even if the rectangular bogies are stacked, it is difficult to stack the bogie bogies in three or four or more stages for safety, which requires a large space for storing the rectangular bogies.

In addition, there is a problem in that the risk of work increases due to safety bumps caused by collision with a crushing bogie, which may collide with surrounding facilities as well as the bogie due to inclination and collapse of the rectangular bogie stacked on the upper side.

In order to stably stack the rectangular cart, a storage box is partially installed on one side of a work site. However, since the operation time and materials for installing the cart are separately required, productivity and economical efficiency are lowered.

Furthermore, the panel is provided with a metal plate having a predetermined area, so that the weight of the bogie is increased, and the cost of the bogie increases, resulting in an economical disadvantage. In addition, there is a problem that economical efficiency and storage stability are lowered because the size of the panel is increased in order to transport a plurality of boxes at a time.

Korean Utility Model Publication No. 20-2013-0006318

In order to solve the above-mentioned problems, the present invention provides a box-type stacking truck for carrying a freight, wherein a stacked box is stably fixed and a plurality of stacked trucks are stably stacked to improve storage efficiency.

In order to solve the above-mentioned problems, the present invention provides a box-type stacking truck for carrying a freight, the housing having a receiving space, a loading box having a stepped portion projecting downwardly from the bottom thereof, A support panel part having a side frame upwardly protruded to surround a side surface of the cargo loading box along an outer frame of a rectangular shaped bottom frame formed with a hollow corresponding to a projected outer side profile of the step portion; A first alignment surface portion protruding outward from both side edges of one end of the support panel portion and extending upward by a predetermined length, the first alignment surface portion corresponding to the front portion of the side frame centering on each corner, And a second alignment surface portion extending symmetrically with respect to the first alignment surface portion so as to increase the separation width toward the upper end portion; And a rotation transmitting portion including a pair of rotary casters fastened to both sides of the bottom surface of the support panel portion so as to be changeable in direction and a pair of fixed casters fastened to both sides of the other end surface portion, The length of the laminated alignment jig is extended so that the upper end and the lower end of the laminated alignment jig, which are arranged vertically adjacent to each other when stacking the cargo transportation laminated truck, are mutually laminated, And the length of the box-shaped freight transporting lane corresponds to one length.

Preferably, one end of the laminated alignment jig is spaced apart from the bottom surface of the bottom frame by a predetermined distance so as to be stepped with the outer surface of the side frame, and the upper and lower ends of the laminated alignment jig are formed to have mutually corresponding profiles .

Through the above-mentioned solution, the box-fixed freight transporting laminated bogie according to the present invention provides the following effects.

First, a stepped portion protruding downward from the bottom of the box is fitted and fixed in a hollow opening at a central portion of the bottom frame, so that even if there is no separate fixing means, the box is detached from the bogie even during a sudden change of direction So that safety and convenience of carrying can be remarkably improved.

Second, since the hollow is formed in the bottom frame, material and cost are remarkably reduced, and the laminated alignment jig, which is provided at one end of the support panel part, is fluidly rotated when stacking the carts. Instead, since they are stably stacked and supported, they can be stacked as high as about 20 stages and can be compactly stored, thereby providing a synergistic effect in which space utilization is remarkably improved.

Third, since the extended length of the laminated alignment jig is corresponding to the length of the rotation transmitting portion and the thickness of the bottom frame, the supporting panel portion of the stacked car is substantially parallel to the bottom surface, It can be stably aligned and supported.

2 to 6, the box-fixed freight transporting laminated bogie 100 according to the present invention is provided with a support panel portion 10, a rotary transfer portion 20 and a lamination alignment jig portion 30 . In the meantime, the 'bogie' to be described later in this embodiment substantially corresponds to the 'box-fixed freight transporting ladder', and the 'box' is understood to mean substantially correspond to the 'cargo loading box'. In addition, 'later-described bogie' or 'upper bogie' and 'lower bogie' or 'lower bogie', which will be described later, are substantially the same type of bogie, and are divided to describe positions stacked up and down Understanding is desirable.

In detail, in the box-fixed type cargo transportation stacking truck 100 according to the present invention, the cargo loading box 50, in which the cargo is stored above the support panel unit 10, And can be stored in a compact manner by stacking multiple layers selectively in storage.

The cargo loading box 50 has a bottom 52 having a rectangular shape and a predetermined area and a side wall 51 extending upwardly along the outer rim of the bottom 52 to be accommodated Space is formed. At this time, the step portion 53 is preferably protruded downward from the bottom portion 52. Here, the step portion 53 may protrude from the bottom edge of the bottom portion 52 at predetermined intervals.

At this time, the profile of the outer circumferential surface 53a of the step portion 53 may be formed to correspond to the inner circumferential surface profile of the side portion 51. Accordingly, when the cargo loading box 50 is stacked and stored, the box stepped portions 53 stacked on the upper side can be stably stacked on the inner circumferential surface on the upper side of the side portion 51 of the box provided below. When the cargo loading box 50 is loaded on the car 100, the step portion 53 may be inserted into the hollow 11b of the bottom frame 11 to be described later.

The support panel 10 is provided with the side frame 12 protruding upward so as to surround the side portion 51 of the box 50 along the outer rim of the rectangular bottom frame 11. At this time, it is preferable that a hollow 11b corresponding to the profile of the outer side surface 53a of the stepped portion 53 is formed on the center portion of the bottom frame 11.

In detail, the support panel 10 may be formed into a hollow square frame by cutting an "L" -shaped steel sheet or a plate member bent so that both sides thereof are orthogonal to each other to a predetermined length, and then welding the adjacent both ends. Accordingly, the bogie 100 can be easily manufactured, and the weight of the bogie 100 itself can be minimized, so that the ease of carrying can be significantly improved.

In addition, the bottom frame 11 may have a cross-sectional area of an extent such that the outer frame side of the bottom 52 of the cargo loading box 50 can be restrained as the hollow 11b is formed, It is economical because the material used is minimized. Of course, a reinforcing frame (not shown) may be further provided on the bottom frame 11 to cross the hollow 11b so as to reinforce the support strength of the cargo loading box 50.

Here, the support panel unit 10 may be made of various known metal steel or steel plate materials, and may be made of a high strength synthetic resin material such as fiber reinforced plastic.

3, when the cargo loading box 50 is loaded on the car 100, the side portion 51 of the cargo box 50 is housed inside the side frame 12, And the step portion 53 is fitted and fixed in the hollow portion 11b.

That is, the stepped portion 53 protruding downward from the bottom portion 52 of the box 50 is fitted into the hollow 11b opened at the center of the bottom frame 11, Can be stably fixed to the support panel part (10). Accordingly, the state in which the box 50 is substantially firmly received in the support panel unit 10 can be fixed even if there is no separate fixing means. Accordingly, the box 50 can be prevented from being separated from the carriage 100 due to a centrifugal force due to an external impact or a sudden change of direction when the carriage is conveyed, so that convenience of transportation and safety can be remarkably improved.

Further, since the inner rim profile of the step portion 53, the side surface portion 51 of the box, and the hollow 11b of the bottom frame 11 are formed to have substantially mutually corresponding sizes, The transport efficiency can be further improved since it can be stably transported even in a state where the transport rollers 100 are stacked on the upper side in multiple stages.

At this time, the side portions 51 of the box box 50 are constrained to the inner circumferential surface of the lamination alignment jig 30 to be described later, so that stability in transportation can be further improved.

In addition, it is preferable that the rotation transmitting portion 20 is provided at the lower end of the support panel portion 10. The rotary transfer unit 20 includes a pair of rotary casters 21 that are coupled to both sides of the lower surface of the one end of the support panel unit 10 such that the rotary casters 21 can be switched in direction, And a pair of fixed casters 22 to be fastened.

4 to 5, the caster 21, 22 of the truck 100B disposed on the upper side of the truck 100A, 100B for multi-stage stacking for the storage efficiency, And is accommodated in the support panel portion 10 of the carriage 100A.

Specifically, the casters 21 and 22 provided at the lower end of the upper truck 100B are seated on the inner surface 11a of the bottom frame 11 of the lower truck 100A, It can be prevented that it is released to the outside.

At this time, since the fixed castors 22 are fixed to rotate in correspondence with the longitudinal direction between one end and the other end of the support panel 10, even if the width of the sectional area of the bottom frame 11 is narrow, Can be maintained.

On the other hand, since the rotatable casters 21 are freely rotatably and freely rotated by impacts or vibrations from the periphery and are pulled toward the hollow 11b of the bottom frame 11, the multi-stage stack of the trucks 100A, it's difficult. Further, even if the trucks 100A and 100B are stacked in multiple stages, they tend to be easily tilted and collapsed.

Accordingly, the present invention discloses a structure for solving the above-mentioned problems.

In detail, it is preferable that a pair of the lamination alignment jig portions 30 are further provided on the both side edges 12a of the support panel portion 10 at one end. One end of the stacking alignment jig 30 may protrude outwardly from one end edge 12a of the support panel 10 and extend upward to a predetermined length. At this time, one end portion of the lamination alignment jig 30 is preferably the same portion as the lower end portion 30b of the lamination alignment jig 30 described later.

Of course, the lamination alignment jig 30 may be provided on both side edges of the other end of the support panel 10, but may be provided at both ends of one end of the support panel 10 with the rotatable casters 21 12a.

That is, one end side of the lower side carriage 100A and the upper side adjacent to the upper side carriage 100B is supported by the fixed type caster 22. The other end side can be freely rotated and freely rotated so that it can be vertically aligned and supported by the lamination alignment jig 30 in place of the rotary caster 21 which can be released to the hollow 11b side.

Accordingly, even if the trucks 100A and 100B are stacked at a high height, the truck can be stably and compactly stored, and space utilization can be remarkably improved. In addition, since materials necessary for manufacturing the trucks 100A and 100B are minimized, manufacturing time and manufacturing cost can be remarkably reduced.

The upper end portion 30a of the lamination alignment jig 30 provided on the lower side carriage 100A at the time of stacking the bogie is positioned at one end side of the support panel portion 10 included in the upper side carriage 100B, And may extend upward to a length corresponding to the lower end 30b of the lamination alignment jig 30 provided on the upper truck 100B. Therefore, the upper end portion 30a and the lower end portion 30b of the laminated alignment jig 30, which are respectively provided in the stacked bogies 100A and 100B, are arranged to be adjacent to each other.

The extended length L1 of the lamination alignment jig 30 so that the adjacent upper end portion 30a and the lower end portion 30b of the lamination alignment jig 30 disposed above and below are laminated and supported, It is preferable that the length corresponds to a length obtained by adding the height L2 of the transmitting portion 20 and the thickness L3 of the bottom frame 11. [ One end of the lamination alignment jig 30 is spaced apart from the lower surface 11c of the bottom frame 11 by a predetermined gap g and straddled with the outer surface of the side frame 12 .

That is, the laminated alignment jig 30 extends to correspond to the length L2 of the rotary transfer unit 20 and the thickness L3 of the bottom frame 11, One end side between the carriages 100A and 100B can be supported by the lamination alignment jig 30. [ It is preferable that the one end side between the carriages 100A and 100B is substantially one end side between the support panel portions 10 of the carriages 100A and 100B.

Accordingly, even if the rotary caster 21 of the upper truck 100B is free to rotate freely, it is supported by the lamination alignment jig 30, so that the upper and lower trucks 100A and 100B can be stably fixed to each other .

The extended length L1 of the laminated alignment jig 30 corresponds to a length obtained by adding the height L2 of the rotary transfer unit 20 and the thickness L3 of the bottom frame 11 Since the respective support panel portions 10 of stacked trucks 100A and 100B are provided substantially parallel to the bottom surface, they can be stably aligned and supported even if stacked in multiple stages.

One end of the lamination alignment jig 30 is separated from the bottom portion 11c of the bottom frame 11 by a predetermined gap g so that the lower end 30b of the lamination alignment jig 30 A stepped portion 30c is formed between the outer surfaces of the side frames 12. [

That is, the upper end portion 30a of the stacking alignment jig 30 of the lower truck 100A is in close contact with the outer surface of each of the corners 12a, but the step portion 30c of the adjacent upper side truck 100B is caught So that the position can be aligned. Accordingly, even if the bogies 100A and 100B are continuously stacked in the upward direction, the substantial vertical alignment can be guided, so that a large quantity of bogies can be stably stacked.

At this time, the upper end 30a and the lower end 30b of the lamination alignment jig 30 are preferably formed to have mutually corresponding profiles.

That is, when the upper end 30a of the lamination alignment jig 30 is formed horizontally and flat, the lower end 30b may be horizontally and flatly formed to correspond to the upper end 30a. Alternatively, if the upper end 30a of the lamination alignment jig 30 is inclined from the center side to both ends, the lower end 30b may be inclined so as to correspond to the upper end 30a. The lower end portion 30b of the stacking alignment jig 30 of the upper truck 100B stably contacts closely with the upper end portion 30a of the stacking alignment jig 30 of the lower truck 100A and stacked and supported .

A restraining protrusion (not shown) is formed in an extending direction at one end of the upper end 30a and a lower end 30b of the lamination aligning jig 30 and the restraining protrusion (not shown) A restraining groove portion (not shown) may be formed. At this time, it is preferable that the extension direction is understood to be the longitudinal direction of the lamination alignment jig 30.

That is, the upper end 30a and the lower end 30b of the stacking alignment jig 30 adjacent to each other are in close contact with each other and the restraining protrusion (not shown) is inserted and restrained in the restraining groove (not shown) The vertically stacked state of the substrate 100 may be more firmly supported.

In addition, a buffer pad (not shown) may be further provided on the upper end 30a of the lamination alignment jig 30. [ Here, the buffer pads (not shown) may be formed of elastic members such as a rubber plate for covering the end faces of the upper end portions 30a of the lamination alignment jig 30. Accordingly, it is possible to prevent the laminated alignment jig 30 from being deformed, broken or separated due to an impact upon stacking the carriage 100, and by the elastic frictional force of the buffer pads (not shown) 100 may be more stably fixed.

The laminated alignment jig 30 may be formed such that the first aligned surface portion 31 and the second aligned surface portion 32 are orthogonal to each other with respect to the longitudinal center portion. The first alignment surface 31 corresponds to the front surface of the side frame 12 at each edge 12a of the support panel 10. The second alignment surface portions 32 are disposed on both side portions of the side frame 12 so that the inner surfaces thereof face each other.

That is, the stacking alignment jig 30 is provided to simultaneously cover both sides of each edge 12a of the support panel 10, so that the stacked bogie 100 stacked vertically is more reliably aligned Can be stacked.

Here, the first alignment surface portion 31 may extend to correspond to the other end portion of the support panel portion 10, and preferably be parallel to each other. The second alignment surface portion 32 may extend symmetrically with respect to the upper end 30a of the stacking alignment jig 30 so as to extend the separation width.

That is, as shown in FIG. 4, the carts 100A and 100B stacked vertically are stacked vertically stably on the inner surface of the first aligned surface portion 31 by closely aligning with the neighboring stepped portions 30c .

5, the second aligning surface portion 32 extends obliquely outwardly at a predetermined angle .theta..degree. Toward the upper end, so that the interference with the rotary caster 21 is minimized, .

At this time, the second alignment surface portion 32 may be inclined at an angle of 1.2 to 1.7 degrees. As a result, interference with each other during lamination of the carriage 100 is minimized, and the portion protruding to the outside is minimized, so that storage efficiency can be remarkably improved.

The laminated alignment jig 30 is formed by cutting an "L" -shaped steel sheet or a plate material bent to make both sides orthogonal to each other by a length L1 as described above so as to cover both edges 12a at one end of the support panel portion 10 And can be provided as a simple method of fixing.

Also, since the laminated alignment jig can be applied to a conventional square bogie as a simple method of fixing the ladder alignment jig to each corner of one end provided with a rotary type castor, the usability can be remarkably improved.

Accordingly, in the box-fixed type cargo transportation stacking truck 100 according to the present invention, a step portion 53 protruding downward from the bottom portion 52 of the box 50 is inserted into the hollow portion of the hollow frame It is possible to prevent the box from being dislocated from the carriage even when an external shock or sudden change of direction is caused during transportation. As a result, the convenience of transportation and safety using the bogie 100 can be remarkably improved.

In addition, since the hollow 11b is formed in the bottom frame 11, the laminating alignment jig 30, which is provided at one end of the support panel 10, And is stacked and supported in place of the rotatable casters 21 which are fluidly rotated when the bogie 100 is stacked.

Accordingly, since the bogie 100 is vertically aligned and compactly stored, the stationary state can be maintained while improving space utilization. Therefore, unlike the conventional unstable laminated structure (see FIG. 1), even when the rectangular lanes are stacked in three to four stages, a stable lamination state can be maintained even if the laminated structure is formed by 20 stages, as shown in FIG. As a result, since many trucks can be stacked vertically at a time, space required for storage is minimized, and space utilization can be further improved since a separate storage box is not required to be installed high or wide.

The extended length L1 of the stacking alignment jig 30 corresponds to a length obtained by adding the height L2 of the rotary transfer unit 20 and the thickness L3 of the bottom frame 11 Since the support panel portion 10 of the stacked bogie 100 is provided substantially parallel to the bottom surface, it can be stably aligned and supported even if it is stacked in multiple stages.

As described above, the present invention is not limited to the above-described embodiments, but can be modified by a person having ordinary skill in the art to which the present invention belongs without departing from the scope of claims of the present invention And these modifications fall within the scope of the present invention.
