Description

TECHNICAL FIELD The present invention relates to a device for catching and lifting a brick such as a brick base or a large brick.

2. Description of the Related Art Conventionally, in order to grab and carry a heavy load of bricks, a lifting tool with such an enlarged shape is finally used, and after the brick base material and large bricks are carried to a predetermined position, they are manually moved to 90
The base was raised by rotating it at a predetermined angle of 180 degrees or 180 degrees.

However, the above-mentioned conventional methods damage the brick base to lower the yield and cause back pain to the worker.

Therefore, although the problem can be solved by installing an overturning device for the rotation of the brick base or the large brick, it is impossible to freely convey and rotate it to any place.

Means for Solving the Problems The present invention has been made in view of the above problems, and in order to solve the above problems, the bricks are hung by a crane or a hoist and the bricks are detachably gripped by the clamps and conveyed. In the brick gripping and suspending device of the brick, the attachments are rotatably attached to the clamps of the opposing clamp bodies, and the locks are arranged on the clamps so that the attachments can be fixed at any angle. An object of the present invention is to provide a brick gripping and suspending device which is characterized in that a standing plate is arranged on the lower surface of the clamp body.

Effects According to the present invention, a heavy object such as a brick base material or a large brick can be grabbed by the attachment by the grab and hang device, locked by the lock device and safely transported to a predetermined position by a crane or the like. Then, if you release the lock device at the predetermined position,
The attachment can be rotated at an appropriate angle such as 90 degrees or 180 degrees, and a heavy object that has been grabbed can be installed by rotating it in a predetermined direction.

Further, by arranging the standing plate on the lower surface of the clamp body, it is possible to stably grab a heavy object without tilting the clamp body, and prevent bricks from being damaged.

Embodiment Hereinafter, the present invention will be described based on an embodiment.

FIG. 1 and the following are embodiments of the present invention. As shown in FIG. 1, the gripping and lifting device 1 has an L-shaped clamp body 2
Are opposed to each other, and pins 5 are detachably attached to pivotal support holes 4 opened at regular intervals in the central portion of the horizontal member 3 to adjust the intervals of the pair of clamp bodies 2 to about 300 to 1000 mm. It is formed freely. Then, a chain hanger 6 installed on the upper part of the clamp body 2 is hung by a crane or a hoist (neither of which is shown), and a brick base or a brick base is attached between the attachments 8 attached to the clamp part 7 at the lower part of the clamp body 2. The heavy object 9 of a large brick is sandwiched so that it can be transported to a predetermined position. Attachment 8 is shown in FIG.
As shown in FIG. 2, a slightly wide gripping member 10 is formed in a cylindrical shape projecting to the side, and a bearing 11 is internally provided in a cylindrical attachment 8 to pivotally support it, and each is freely rotatable with respect to the clamp portion 7. Is attached to. As shown in FIG. 3, the grip member 10 is joined to an auxiliary plate 12 having a concave curved surface with a radius of curvature of 3 to 5 m, and is made of a soft material 13 such as felt or urethane foam.
Is attached. Attachment 8 pivoted in this way
A lock lever 15 having a taper-shaped block-like lock device 14 attached to the tip thereof is pivotally attached to the upper part of the clamp body 2 as shown in FIGS. 1 and 2, and the lock device 14 is attached to the attachment 8. The attachment 8 is engaged with the engaging portion 16 such as a key groove formed at a constant interval on the circumferential surface to move the attachment 8 at 90 degrees or 1 degree.
It can be locked by turning an appropriate angle of 80 degrees. Reference numeral 17 denotes an upright plate horizontally fixed to the lower surface of the clamp body 2 so that the gripping and lifting device 1 can be stably installed at a predetermined position.

Then, the space between the clamp main bodies 2 is adjusted, and the clamp body 7 is positioned by suspending it by a crane and grasping and lifting the suspender device 1 by the clamp portion 7 between the heavy objects 9. Then, when the gripping and lifting device 1 is lifted by the crane, the heavy object 9 can be gripped by the clamp part 7, and when the lock lever 15 is operated to release the lock device 14, the attachment 8 becomes rotatable. By turning the attachment 8 and rotating it by a predetermined angle, the heavy object 9 can be swung in a predetermined direction. The turning of the heavy object 9 can be performed before or after the transportation. Then, the lock lever 15 is operated to engage the lock device 14 with the engagement portion 16 to fix the attachment 8, and the crane is used to transport the gripper lifting device 1 to a predetermined place.

In this way, even if the weight is 30 to 50 kg or more,
In particular, it is possible to appropriately adjust the width of the clamp body without installing a tipping device, and to easily rotate a heavy object in a predetermined direction and move it to a predetermined position with the gripping and lifting device. Since the standing plate is horizontally fixed to the lower surface of the clamp main body, the main body can be stably grasped without tilting, and the brick can be prevented from being damaged.

In particular, in this embodiment, the attachment surface is a concave curved surface,
Since it is covered with soft material such as felt or urethane foam, it can securely prevent heavy objects from slipping, and even if it is a brick base material that easily touches the end surface and the corner part is easily chipped, the corner part does not chip , Which can be rotated and moved in a predetermined direction.

Further, although the attachment is circular in the above description, it may be replaced with an appropriate shape such as a polygonal shape depending on the shape of the object to be processed.

In the above embodiment, the lock device is the key lock system, but it may be a magnet lock system or a brake band that is detachably attached to the side peripheral surface of the attachment with a magnet holder. It is also possible to attach an oil motor or the like to the portion and to control the rotation speed of the attachment by restricting the flow of oil so that the attachment can rotate safely.

Effects of the Invention As described above, according to the present invention, it is easy to use the lifting device to grab the foundation of heavy objects such as bricks of 30 kg or more and large bricks. The device can be easily rotated and locked at an appropriate angle, and can be transported to a predetermined position by a crane or the like. Further, since the standing plate is arranged on the lower surface of the clamp body, it is possible to stably grab a heavy object without tilting the clamp body and prevent the brick from being damaged. Brick corners can be prevented from being damaged,
The yield can be improved, the labor of the worker can be reduced, and the occurrence of backache failure can be prevented.
