Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a manual cart.

[0002]

[Prior Art]

A manual trolley is carried by a worker carrying a load such as a heavy load. Below, as an example of the load, a sleeper for storing steel materials such as coils is taken as an example, and the specification is a volume of 210 × 140 × 2000. A case where a sleeper having a weight of (mm ³ ) and a weight of 55 (kg) to 60 (kg) is handed will be described.

In contrast to such sleepers, the conventional manual trolley cannot be applied to handling because of a structural defect in the mounting support of the sleepers and the like. Therefore, conventionally, when handling the above-mentioned sleepers, the sleepers are transported to a predetermined position by a luggage transport vehicle such as a forklift in an area where the work area is large, and in a region where the work area is unusable by the luggage transport vehicle, It was common for workers to lift and move the sleepers directly.

That is, two workers were set as a set, and each worker carried out handling by lifting the end of the sleepers, carrying them, and setting them. In an example of a process, a total of 4 (2 (persons) x 2 (groups)) are engaged in one process when transporting sleepers, and an additional 2 (persons / day) is required when busy and work efficiency is high. The average was 5 (process / day).

[0005]

[Problems to be solved by the device]

 Conventionally, improvement of workability in handling such as sleepers under the above circumstances has not been considered, work efficiency is low due to labor saving of workers, and work is inefficient. However, there was a situation where effective measures could not be taken.

The present invention has been made in view of the above problems, and provides a manual trolley that is effective even in a work situation where the work area is small, thereby reducing the human work of the worker and the ability to transport the load. The purpose is to improve the rate.

[0007]

[Means for Solving the Problems]

 In the above-mentioned problem, in a manual cart in which a handle is formed at the upper end of a carrier for a load and a wheel is pivotally supported at the lower end, there is provided a mesh receiving plate fixed to the carrier and a meshing plate facing the mesh receiving plate. However, opposite teeth are formed at the lower end of each plate for holding the load, and the meshing plate is pivotally supported in the front and rear direction on the projecting edge of the mesh receiving plate for meshing. The upper part of the plate is projected toward the carrier side, the protruding edge is rotatably supported on the lower end of the movable joint plate, and the upper end of the movable joint plate is connected to the lower end of the lock joint plate via a spring. A manual operation characterized in that the upper end is connected to the tip of a lock lever receiver that is rotatably supported by a carrier, and the tip of the lock lever is fixed at the connection point between the lock joint plate and the lock lever receiver. Achieved by a dolly.

[0008]

[Action]

 According to the manual carriage of the present invention, after the carriage is aligned with the load body, the operator operates the lock lever to hold the load body by the catch receiving plate and the meshing plate. Since the load of the load is mostly applied to the trolley, the labor of the worker in handing such as lifting, transfer and setting of the load is reduced.

[0009]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1 and FIG. 2, in the manual carriage according to the embodiment, a carrier 1 formed by connecting a pair of vertical members with a horizontal member is configured as a central member, and the upper end of the carrier 1 is curved to form a carriage. Is formed with a handle 2 for the moving operation. A pair of wheels 3 are supported by a shaft 4 on the rear side of the lower end of the carrier 1, and the shaft 4 is supported by a bearing member 5 connected to the carrier 1.

On the front side of the lower end of the carrier 1, a bite plate 6 fixed to the carrier 1 and a bite plate 7 protruding further forward of the bite plate 6 are mounted. The lower ends of the bite plate 6 and the bite plate 7 are located slightly above the lower end of the carrier 1, and at the lower ends of the plates, facing teeth for sandwiching the sleepers 8 are formed. The meshing plate 7 is pivotally supported by the protruding end of the meshing plate 6 so as to be rotatable in the front-rear direction. The protruding end of the meshing plate 7 is rotatably supported by a movable joint plate 9 facing upward, and the movable joint plate 9 is connected to a lock joint plate 11 via a spring 10. The upper end of the lock joint plate 11 is connected to a lock lever receiver 12 for opening and closing the engagement plate 6 and the engagement plate 7 and a lock lever receiver 13 rotatably supported on the carrier 1. That is, the upper end of the lock joint plate 11 is pivotally supported by the tip of the lock lever receiver 13, and the tip of the lock lever 12 is fixed at the same position. As shown in FIG. 3, a reinforcing plate 14 is arranged according to the length of the spring 10.

In the above structure, when the carriage is aligned so that the sleeper 8 is located under the bite plate 6 and the bite plate 7 as shown in FIG. 1, and the lever 12 is rotated backward, The lock lever receiver 13 rotates backward with a connection point with the carrier 1 as a fulcrum. The rock joint plate 11 rises in accordance with the rotation of the lock lever receiver 13 and is pivotally displaced in an inclination that matches the inclination of the lock lever receiver 13. That is, the end of the lock joint plate 11 on the side of the lock lever receiver 13 rotates together with the tip of the lever receiver 13, and the end of the lock joint plate 11 on the side of the movable joint plate 9 rises accordingly. As a result, the spring 10 is urged upward and the movable joint plate 9 is pulled upward, and the meshing plate 7 is pivoted rearward to close, so that the sleeper 8 has the meshing plate 7 and the meshing plate 7 as shown in FIG. It is sandwiched by the bite plate 6. In this state, the trolley can be tilted rearward, the sleepers 8 can be lifted around the wheels 3 as a fulcrum, and the trolley can be conveyed as it is.

As described above, in lifting the sleepers 8, the lever action works, and the load of the sleepers 8 is applied to the carrier 1 at the time of transportation, so that it is not a burden on the worker. After reaching the transfer position, the lever 12 is rotated in the reverse direction to rotate the meshing plate 7 forward to restore the state shown in FIG. 1 and easily release the sleepers 8. can do.

According to this embodiment, since the structure is simple, and the operating principle and the operating procedure are simple, the occurrence of failures is extremely small, the manual cart having excellent durability and workability is provided. Therefore, according to the present embodiment, even when working in a small work area in which a luggage carrier cannot be used, two workers as in the conventional case form a pair and each lifts the end of the sleeper and carries it. It is not necessary to set the work style, and the sleepers 8 can be efficiently handled.

Further, even when lifting the sleepers 8, it is not necessary for the worker to bear the load of the sleepers 8 such as the worker leaning over and carrying the sleepers 8. Therefore, even a single worker can work and fatigue is reduced. The number of workers is low, and the possibility of suffering from backache of workers is reduced, and good occupational health is maintained. In general, labor can be saved, human labor can be reduced, the efficiency of transportation work can be improved, and the work cost can be reduced even when the manufacturing cost of the trolley of the present embodiment is taken into consideration.

Further, in this embodiment, the degree of opening and closing of the tooth-receiving plate 6 and the tooth-engaging plate 7 can be widened, and the same work can be performed on sleepers having different sizes.

In the above-mentioned embodiment, the load was explained as a sleeper, but the present invention is not limited to it, and it is also effective for various heavy loads such as square wood, clay pipe, pipe and the like.

[0017]

[Effect of the device]

 As described above, according to the present invention, a manual trolley having excellent durability and high workability is provided. Therefore, it is possible to reduce the human work of handling such as transporting a load in a small work area and reduce the efficiency. The effect that it can be performed well is exhibited.
