JP 2015-67948 A

In the carrier described in Patent Document 1, the effect of preventing the load cone placed on the pedestal from falling is insufficient. In addition, at construction sites, etc., the road surface is often uneven, and it may be difficult to move with casters.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and a main object thereof is to provide a carrier capable of carrying an object while suitably preventing it from falling.

A first configuration is a carrier used for carrying an object to be carried, which includes a plate-shaped base and a cone-shaped cone portion erected on the base, wherein the base is supported from below. an elongated belt attached to the mounting portion and capable of suspending the mounting portion; a belt capable of contacting the cone portion; and a holding portion in which change is suppressed.

In the first configuration, as the change in the relative position between the placing section and the holding section is suppressed, the change in the relative position of the object to be transported, which is supported by the placing section and in contact with the holding section, relative to the carrier is suppressed. be. Therefore, when an object to be transported is transported by suspending the placing portion using the belt, it is possible to prevent the object to be transported from falling from the transporter or shifting the placement position on the transporter. .

In a second configuration, in addition to the first configuration, the holding portion can be fitted onto the cone portion, and separation from the placing portion is suppressed at a position where the holding portion is fitted onto the cone portion.

If the holding portion can be fitted onto the conical cone portion, movement of the cone portion in the front-rear and left-right directions can be suppressed only by suppressing the separation from the placement portion. Therefore, in the second configuration, it is possible to prevent the object to be transported from falling from the transporter or shifting its position on the placing section with a simple configuration.

In a third configuration, in addition to the first or second configuration, the holding portion is attached so as to be movable in the extending direction of the belt.

In the third configuration, since it is possible to change the relative position of the holding section with respect to the placing section, it is possible to cope with an increase or decrease in the number of objects to be transported to be placed.

In a fourth configuration, in addition to any one of the first to third configurations, the holding portion includes an outer fitting portion that can be fitted onto the cone portion, and a passage hole through which the belt can pass. The belt passes through the passage hole in a double manner, and the lower end side thereof is connected to two spaced apart places in the mounting portion, and the passage hole is the mounting portion in the passage direction of the belt. widens toward the sides.

In the fourth configuration, when the holding portion is brought closer to the placement portion side and lifted in a state where the outer fitting portion is fitted onto the cone portion, the weight of the object to be transported causes the belt in the passage hole to move. Tension is applied to the outside, the belt is pressed against the inner surface of the passage hole, friction increases, and sliding along the belt in the direction away from the placing section can be suppressed. In addition, since it is possible to obtain the effect of suppressing the sliding of the holding portion by the shape of the holding portion, the holding portion and the mounting portion do not need to separately provide a member for suppressing a change in the relative position between the holding portion and the mounting portion. A change in the relative position with respect to the placement section can be suppressed.

In a fifth configuration, in addition to any one of the first to fourth configurations, the writing portion includes a contact portion that protrudes upward and is capable of coming into contact with the outer edge of the base portion.

In the fifth configuration, the abutting portion can suppress the sideways movement of the object to be transported on the placing portion, so that the displacement of the object to be transported during transportation can be preferably suppressed.

In a sixth configuration, in addition to any one of the first to fifth configurations, the belts are attached to opposing positions on the outer edge of the placing section.

In the sixth configuration, the object to be transported can be placed so as to be sandwiched between the belts, so that the belt can prevent the object to be transported from being displaced or dropped. In addition, since the center of gravity of the carrier can be positioned between the belts, stability during transportation can be improved.

A holding portion 40 shown in FIGS. 9 to 13 is attached to the second belts 32 and 33 . The holding portion 40 is made of hard resin. The holding portion 40 includes an annular outer fitting portion 41 having a substantially constant height and thickness. The inner diameter of the outer fitting portion 41 is substantially equal to the outer diameter of the load cone 100 at a position a predetermined distance below the upper end of the cone portion 101 . Further, the inner diameter of the outer fitting portion 41 is slightly expanded downward, and the inclination angle of the inner side surface with respect to the central axis is substantially equal to the inclination angle of the cone portion 101 .

Extending portions 42 and 43 extending to the left and right sides are provided on the outer peripheral surface of the outer fitting portion 41 . The heights of the extending portions 42 and 43 in the vertical direction are substantially equal to the height of the outer fitting portion 41, and the widths in the front-rear direction are substantially constant.

Each of the extending portions 42 and 43 is provided with passage holes 42a and 43a that are vertically open and extend in the horizontal direction. The cross section of the passage holes 42a and 43a in the plane perpendicular to the left-right direction (the AA line cross section) is substantially constant in the left-right direction. The widths of the passage holes 42a and 43a in the front-rear direction are uniformly widened in the front-rear direction toward the lower end, and the cross-sectional shape thereof is an isosceles trapezoid. In addition, the inclination angle of the passage holes 42a and 43a with respect to the vertical direction is a straight line passing through the connecting portions 34 and 35 and the side of the connecting portion 23 attached to the short shaft pipe when the belt 30 is extended vertically upward. with respect to the vertical direction. At the upper ends of the passage holes 42a and 43a, there are saw-toothed teeth 42b which project inwardly of the openings so as to reduce the width of the openings and protrude upward. 43b is formed over the entire left-right direction. The holding portion 40 is a pair of members of the same shape, each having elongated portions forming extension portions 42 and 43 provided at both ends of a semi-arc portion forming an outer fitting portion 41 , and screwed together by screws 44 . It consists of connecting

The second belts 32 and 33 described above pass through passage holes 42a and 42b provided in the extensions 42 and 43, respectively. At this time, since the space between the upper ends of the passage holes 42a and 43a is narrowed and the tooth portions 42b and 43b are provided, the overlapping state of the second belts 32 and 33 is maintained. On the other hand, on the lower end side of the passage holes 42a and 43a, the gap is widened, so that the double second belts 32 and 33 can be separated from each other.

A case where the load cone 100 is carried by the carrier 10 configured as above will be described with reference to FIG. A base portion 102 of the load cone 100 is placed on the placement portion 20 . At this time, the bottom surface of the base portion 102 is supported by the upper surface of the support portion 24 provided on the connection portion 23 of the mounting portion 20 . In addition, the outer edge of the base portion 102 is located between the contact portions 25 facing each other and contacts or approaches each contact portion 25 . The long-axis pipe 21 of the mounting portion 20 crosses the opening at the lower end of the cone portion 101 and supports the corner of the boundary between the plate-shaped base portion 102 and the cone portion 101 .

The outer fitting portion 41 of the holding portion 40 is fitted from the upper end side of the cone portion 101 of the load cone 100 , and the inner peripheral surface of the outer fitting portion 41 contacts the side surface of the cone portion 101 . do. At this time, it is preferable that the second belts 32 and 33 are stretched upward and a certain amount of tension is applied to the second belts 32 and 33 .

With the base portion 102 placed on the placement portion 20 as described above and the outer fitting portion 41 fitted onto the cone portion 101, the first belt 31 of the belt portion 30 is suspended. At this time, due to the weight of the load cone 100, a vertical tension, that is, an outward tension is applied to the second belts 32 and 33 in the passage holes 42a and 43a, and the inner surfaces of the passage holes 42a and 43a are pressed against each other to cause friction. increases. Furthermore, at the positions of the teeth 42b and 43b, the second belts 32 and 33 are bent and come into contact with the teeth 42b and 43b, so stress concentrates and friction further increases. Accordingly, it is possible to suppress the sliding of the holding portion 40 along the belt 30 in the direction away from the placing portion 20 . On the other hand, when tension is applied in a direction other than the direction in which the belt 30 is suspended, that is, in either the front, rear, left, or right direction, the contact force of the second belts 32, 33 to the inner surfaces of the passage holes 42a, 43a is small, A sufficient frictional force cannot be obtained, and the position of the holding portion 40 can be changed.

Further, instead of suspending the carrier 10 on which the load cone 100 is placed, casters may be attached to the ground portion 27 and transported using the casters. In this case, the contact portion 25 of the mounting portion 20 can provide a certain effect in preventing the load cone 100 from falling. If the 2-belts 32 and 33 are kept in a state in which a certain amount of tension is applied, the effect of preventing the load cone 100 from falling can be improved. Movement using this caster is effective when moving on a flat road surface, such as inside a warehouse or on a paved road.

When the transportation of the load cone 100 is completed, the holding section 40 is removed from the cone section 101 after the placement section 20 is grounded. At this time, since the belt 30 is no longer suspended, the tension applied to the belt 30 is reduced, thereby reducing the frictional force between the second belts 32 and 33 and the inner surfaces of the passage holes 42a and 43a. That is, the holding portion 40 can be freely moved along the extending direction of the belt 30 . After removing the holding portion 40 from the cone portion 101 , the first belt 31 and the second belts 32 and 33 are wound around the connecting portion 23 of the mounting portion 20 and sandwiched between the connecting portion 23 and the locking portion 26 . In this state, the wound state of the first belt 31 and the second belts 32 and 33 can be maintained.

With the above configuration, the carrier according to this embodiment has the following effects.
