Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a block gripping device that simultaneously grips a plurality of blocks such as a masonry concrete block to stack or unload them.

[0002]

[Prior art]

 Conventionally, the work of stacking and unloading blocks for masonry has been carried out by using an attachment of a construction machine type. These grip-type attachments were often built into the arms of construction machinery.

[0003]

[Problems to be solved by the device]

 However, with the above attachment, many blocks could not be grasped and carried at one time, and work efficiency was poor.

The present invention has been made to eliminate the above-mentioned drawbacks, and an object of the present invention is to provide a block gripping device capable of gripping and lifting a large number of stone blocks at one time and carrying and unloading them.

[0005]

[Means for Solving the Problems]

 A block gripping device of the present invention is a device for gripping and lowering a block, in which a lying elongated substrate is provided, and a plurality of projecting members projecting outward from a side edge portion of the substrate are provided. Alternatively, a plurality of bending members each including a horizontal piece parallel to the above-mentioned substrate fixed in parallel and a vertical piece bent downward from one end of the horizontal piece are provided, and each bending member is provided below the vertical piece. , One of the grasping members for grasping the block is tiltable, and includes a horizontal member that overlaps the horizontal piece of the bending member and a vertical member that bends downward from the end of the horizontal member opposite to the vertical piece. The opening / closing member is provided, and the upper part of the vertical member of the opening / closing member is rotatably connected to the end of the horizontal piece of the bending member opposite to the vertical piece. The other one of the only members is provided so as to be tiltable, a plurality of guide columns are erected on the substrate, and a frame body is provided which is elevated by being guided by the guide columns. The frame body and the opening / closing member are respectively provided. Is a block gripping device in which a vertical member of the horizontal member and an end portion on the opposite side are connected by a chain.

[0006]

[Action]

 In the block gripping device having the above configuration, when the frame is vertically lifted by a construction machine or the like, the chains lift the end portions of the horizontal members of the opening / closing member that are connected to the respective chains, and the entire device lifts. Arrange the blocks you want to move at the position where each opening / closing member comes down, lower the frame from above, and when the bending member lands, the chain will slacken and the horizontal member of the opening / closing member will lower, bending Overlapping on a horizontal piece of material, the spacing between opposing gripping members widens. When the block is placed in this interval and the frame is raised again, the chain is tensioned and the end of the horizontal member of the opening / closing member with the chain is lifted, and the vertical member and the gripping member provided on it. Since the bending member approaches the vertical piece of the bending member, the block can be sandwiched and gripped by both the holding member of the vertical member and the holding member of the vertical piece. Furthermore, if the frame is raised, the block can be lifted together with the entire device.

When the blocks are carried and then unloaded, the frame is slowly lowered, and when the blocks are landed, the chains are slackened, and the vertical members of the opening / closing member can be opened outward to release the blocks.

【Example】

 An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a front view showing a state in which the device is landed and the chain is loosened. 2 is a left side view of the same, and FIG. 3 is a plan view of the same. An elongated substrate (1) lying down is provided, and a plurality of projecting members (2) projecting outward from the side edge of the substrate (1) are provided, one for each of these projecting members (2). , A horizontal piece (3) that is parallel to the substrate (1) is fixed, and a plurality of bending members (which include the horizontal piece (3) and a vertical piece (4) bent downward from one end of the horizontal piece (3) ( 5) is provided. One gripping member (6a) for gripping the block is provided at the lower part of each vertical piece (4) of the bending member (5) in a tiltable manner.

Further, a horizontal member (7) that overlaps the horizontal piece (3) of the bending member (5) and a vertical member that is bent downward from the end of the horizontal member (7) opposite to the vertical member (4). An opening / closing member (9) including the member (8) is provided. A connecting part (10) for rotatably connecting the upper part of the vertical member (8) and the end of the horizontal piece (3) opposite to the vertical piece (4) is provided. That is, the opening / closing member (9) is rotatable in the lever state with the connecting portion (10) as a fulcrum. Further, the other gripping member (6b) facing the above-mentioned one gripping member (6a) is provided at the lower part of the vertical member (8) in a freely tiltable manner.

On the other hand, two cylindrical guide rods (11) are vertically provided on the substrate (1), and a frame body (12) which is guided by the guide rods (11) and moves up and down is provided. The frame body (12) is provided with two tubular guide tubes (13) through which the two guide rods (11) pass. The frame (12) and the end (7a) of each horizontal member (7) opposite to the vertical member (8) are connected by chains (14).

FIG. 1 shows a state in which the chain is slackened after landing. In this state, the end portion (7a) of the horizontal member (7) is lowered, the horizontal member (7) is horizontal, and overlaps the horizontal piece (3). At this time, the vertical member (8) and the lower portion of the vertical piece (4) facing each other are opened, and the gap between the gripping members (6b) and (6a) is widened.

FIG. 4 is a partially enlarged view showing a state in which the chain is strained when the frame body (12) is lifted by a power shovel or the like (not shown). In this state, the end portion (7a) of the horizontal member (7) is pulled up, the horizontal member (7) is tilted, and the opening / closing member (9) works by levering the connecting portion (10) as a fulcrum, and the vertical member (8). Is closer to the inner side, the gap between the gripping members (6b) and (6a) is narrowed, and the tilting is possible, so that the user can fit and grip the block (B) shown by the phantom line.

As described above, the distance between the gripping members (6b) and (6a) may be narrowed or widened depending on whether it is lifted by a power shovel or the like and when it is landed, so it is desired to stack or unload it. Arrange the blocks at the positions where the opening / closing members (9) are descending, land the bending members (5), and apply the blocks between the gripping members (6b) and (6a), and then again the frame body (12). The block, and then lift the block with the gripping members (6b) and (6a), carry it to the desired location, and lower it to bend it. You can stack and unload ku.

The machine for lifting the device of the present invention may be any machine other than a power shovel as long as it can perform lifting work. For example, a crane can be considered.

[0015]

[Effect of device]

 According to the present invention, the lever mechanism works so that a large number of blocks can be grasped at one time, so that a great advantage can be obtained in that a large number of blocks, masonry blocks, etc. can be stacked and unloaded.
