Description

  The present invention relates to a paving material laying machine that transports, installs, and constructs paving materials.

  In recent years, paving blocks such as interlocking blocks and concrete plates have been increasingly used in pavements such as roadways, sidewalks, parking lots, and parks. Pavement blocks having various functions, shapes, and sizes are used in accordance with purposes such as landscape, design, heat shielding, water retention, drainage, water permeability, and greening.

  When building paving blocks, large paving blocks are increasingly used from the viewpoint of landscape and design, but large paving blocks are difficult to carry by one person alone. Some of them are heavy, and many manpowers are required for transportation, installation, and construction by human power. Also, when transporting by vehicle or heavy equipment, there is a limit to the places where they can enter, so at the end, it was necessary to use small equipment and human power that can be turned around.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[Embodiment]
FIG. 1 is a side view of a paving material laying machine according to the present embodiment, and FIG. 2 is a plan view. FIG. 2 is a plan view of a state in which a suspended load (paving block, paving material) W is sandwiched and weights 17a (described later) are not placed. The pavement material laying machine 1 is basically configured by a pedestal 3, wheels 5, struts 7, a handle 9, a clamp suspension 11, a clamp 13, a winch mechanism 15 and a winch operation unit 15a.

  The pedestal 3 is formed in a plate shape, has a pair of wheels 5, and a column portion 7 is connected in a substantially vertical direction. It is preferable that the support | pillar part 7 is provided in the position containing the axle shaft of the wheel 5. FIG. The pedestal 3 may include a weight fixing portion 17. The weight fixing portion 17 can be fixed by placing a weight 17a according to the weight of the suspended load. By providing the weight fixing portion 17, the weight can be adjusted according to the weight of the suspended load, and transportation and construction are facilitated.

  A handle portion 9 is connected to the column portion 7. A handle 9a is provided at the other end of the connecting portion of the handle portion 9 to the support column portion 7, and the carrier operates the pavement material laying machine 1 with the handle 9a. The horizontal length of the handle portion 9 is longer than the horizontal length of the clamp suspension portion 11. Thus, when the pavement material is sandwiched between the clamp portions 13 suspended from the clamp suspension portion 11 and a downward force is applied to the handle 9a, the clamp suspension can be easily suspended by the lever principle using the wheels 5 as fulcrums. The part 11 side can be pulled up vertically upward, and a pavement material can be conveyed. Moreover, when the weight 17a according to the weight of the suspended load is put, it can be transported more easily. In addition, when it is set as the structure which mounts the weight 17a on the pavement material laying machine 1, the length of the horizontal direction of the handle | steering-wheel part 9 can be shortened, and it can also be made a compact design.

  On the opposite side of the column portion 7 to the side to which the handle portion 9 is connected, a clamp suspension portion 11 is disposed. The clamp suspension 11 can be moved up and down along the support column 7 by a winch mechanism 15. In this embodiment, the support column 7 is composed of a support column 7a and an auxiliary support column 7b, the handle unit 9 is connected to the support column 7a, and the clamp suspension 11 is configured to move up and down along the auxiliary support column 7b. 7a and auxiliary column 7b may be integrated.

  A clamp portion 13 is suspended from the clamp suspension portion 11. The clamp part 13 is configured by a four-node cross link mechanism. The operation of the clamp unit 13 will be described later. As shown in FIG. 1, the connection portion between the clamp suspension portion 11 and the clamp portion 13 may be a universal portion 19 that rotatably connects the clamp portion 13 to the clamp suspension portion 11. Since the connecting portion is the universal portion 19, the suspended load can be rotated 360 degrees and fixed at an arbitrary angle, and fine adjustment of transportation, installation, and construction becomes possible. Moreover, the connection position of the clamp suspension part 11 and the clamp part 13 can be changed, and the height from the lower end of the clamp part 13 to the clamp suspension part 11 can be changed. Moreover, the clamp part 13 may be removable.

  The clamp part 13 has a pair of claws 13a and 13b. The clamp portion 13 is lifted by the clamp suspension portion 11, and when the four-bar cross link mechanism is operated so that the joint 13c at the upper end portion is separated from the opposing joint 13d, the claws 13a and 13b formed at the end portions are paved. While the material is sandwiched, the claws 13a and 13b formed at the ends release the paving material when the four-joint cross-link mechanism is operated so that the joint 13c at the upper end is close to the opposing joint 13d. FIG. 3 is a side view of a state in which a suspended load of the pavement material laying machine is lifted. The horizontal length of the claws 13a and 13b is preferably at least one half of the length of the side between which the paving material is sandwiched, and more preferably at least two thirds. Thereby, a force does not concentrate on a part of edge | side where a pavement material is clamped, but a pavement material can be clamped stably.

  The clamp part 13 is good also as a structure which can make the clamping width | variety with respect to a pavement material variable by changing the position of the joint 13d. Thereby, one type of clamp part 13 can respond to the widths of a plurality of types of suspended loads, and even when handling suspended loads of different widths, the labor of replacing the clamp parts 13 can be saved. FIG. 4 is a schematic view of the clamp portion 13 with the clamping width changed. Moreover, the clamp part 13 may be provided with the opening prevention stopper in order to prevent the fall of the unintended suspended load from the state which clamped the suspended load.

  In the winch mechanism 15, a winch operation portion 15 a is provided on the handle portion 9. By operating the winch operation part 15a, the wire 15b connected to the clamp suspension part 11 is wound or sent out, and the clamp suspension part 11 moves up and down along the auxiliary column 7b. In the present embodiment, the winch mechanism 15 is configured to be operated by human power, but may be electrically operated.

  The winch mechanism 15 allows the clamp unit 13 to move up and down while holding the suspended load. In addition, the suspended load can be released by operating the winch operation portion 15a from the state where the suspended load is sandwiched to land the suspended load and further loosening the wire 15b. That is, in this embodiment, the clamp part 13 is a four-node cross link mechanism, and the winch mechanism 15 holds the suspended load by allowing the clamp suspended part 11 and the clamp part 13 to descend after the suspended load has landed. Has the function of releasing the state.

  Since the winch operation part 15a is provided in the handle part 9, the carrier can operate the winch operation part 15a at hand, and it is possible to lift and unload the suspended load while releasing the sandwiched suspended load. Therefore, even one person can easily carry and install the pavement material.

  The base 3 may be provided with a brake 21 that fixes the wheel 5, and the handle portion 9 may be provided with a brake operation portion 21 a that operates the brake 21. FIG. 5 is a conceptual diagram of the brake 21. The brake 21 includes a brake operation unit 21a, a brake wire 21b, an index plunger 21c, and a spur gear 21d. The spur gear 21d is provided on the shaft of the wheel 5, and normally, the pin 21e of the index plunger 21c is engaged with the tooth groove of the spur gear 21d to lock the wheel 5. When the brake operation unit 21a is operated, the brake wire 21b is pulled, the pin 21e of the index plunger 21c is retracted, and the wheel 5 is unlocked to be rotatable. Thus, since the brake is always applied normally, the paved material laying machine 1 can be kept stopped even on a slope.

  The handle part 9 may be provided with a stand part 23 for allowing the pavement material laying machine 1 to stand on its own. The presence of the stand unit 23 allows the pavement material laying machine 1 to be self-supporting even when the transporter releases the hand from the handle unit 9 or the like. It is preferable that the stand part 23 is a structure which can change height.

  In addition, said embodiment is an example and this invention is not necessarily limited to this.

  As explained above, according to the paving material laying machine, it is possible to lift and unload a suspended load while catching the suspended load, and catch and release the suspended load. It is possible to transport and install pavement materials.
