Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "vertical", "upper", "lower", "horizontal", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.

In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; either directly or indirectly through intervening media, or through the communication between two elements. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

Referring to fig. 1-3, the present invention provides a technical solution: precast concrete block holder, including first arm of force 2 and second arm of force 3, first arm of force 2 runs through the inside of second arm of force 3, and through swing joint between first arm of force 2 and the second arm of force 3, lug 1 is installed to the equal symmetry in top of first arm of force 2 and second arm of force 3, swing joint has opening snap ring 6 on the lower lateral wall that second arm of force 3 is close to the top, open one's mouth and collude 5 on the lateral wall of first arm of force 2 and with opening snap ring 6 terminal corresponding position department install, there is the pull rod all in the activity between second arm of force 3 and the first arm of force 2, and cardboard 4 is all installed to the inboard that second arm of force 3 and first arm of force 2 are close to the bottom.

In this embodiment, preferably, the pull rod includes a fixing portion 7, a tightening spring 8 is installed inside the fixing portion 7, both ends of the tightening spring 8 are connected to a connecting portion 9, the pull rod can provide partial pulling force required by the clamping device for clamping, and the clamping device can have a limiting function.

In this embodiment, preferably, the side wall of the clamping plate 4 is provided with anti-slip lines, so that the clamping stability is increased.

In this embodiment, the first force arm 2 and the hook 5 are preferably of an integral structure.

The utility model discloses a theory of operation and use flow: when the device is used, the two lifting lugs 1 of the clamp holder are hung by matching with a crane, the clamp holder is clamped in the opening hook 5 by using the opening clamping ring 6 before working, and the opening of the first force arm 2 and the second force arm 3 cannot be reduced due to the limitation of the opening clamping ring 6, so that the clamp holder opens the clamping opening before working and enters a preparation working state;

as shown in fig. 3, the clamp is placed above the precast concrete block 10 in a working state, the bottom surface of the pull rod is ensured to be in contact with the top of the precast concrete block 10, the flared snap ring 6 is rotated to prevent the flared snap ring 6 from being in contact with the flared hook 5, at the moment, the flared openings of the first force arm 2 and the second force arm 3 can be reduced, the crane is lifted upwards to reduce the height of the first force arm 2 and the second force arm 3 and clamp the precast concrete block 10, and the clamping force is about 3 times of the dead weight of the block as the stressed node is positioned at the position where the force arm deviates from the stress direction and has a length proportion of about 1 to 3;

during unhooking, after the concrete prefabricated block 10 is put down after the concrete prefabricated block 10 is hung to required position, continue below second arm of force 3 and make the mouth of a mouth snap ring 6 catch on the mouth of a mouth and collude 5 after, lift second arm of force 3 again, the mouth of a mouth of first arm of force 2 and second arm of force 3 just can increase to realize the unhooking, and do not need manual operation in the implementation, thereby can get into next work flow fast.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
