Description

Technical Field

[0001] The utility model relates to the technical field of building construction measurement, in particular to an anti-swinging heavy hammer. Background Art

[0002] In the process of finding the verticality of existing building installation components, because the hanging line of the heavy hammer (plumb bob) is generally very long, when the heavy hammer (plumb bob) is subjected to external forces, such as wind, the heavy hammer (plumb bob) will swing back and forth for a long time, making it difficult for operators to perform vertical positioning. In this case, the operators either rely on the swing amplitude of the heavy hammer to determine the projection point, but the vertical accuracy is low; or they let it stand until the heavy hammer stops swinging, which affects the construction progress. Utility Model Content

[0003] The utility model aims to provide an anti-swinging weight, which solves the problem that the weight swings for a long time under the action of external force during the process of verticality search for component installation.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] An anti-swing weight comprises an outer weight body, a weight upper cover, a damping ball, a suspension line nose, a first suspension line and a water retaining arc plate, wherein a hollow portion is arranged on the outer weight body, the top of the outer weight body is sealed at the hollow portion by the weight upper cover, a damping ball is suspended in the hollow portion, the damping ball is flexibly connected to the bottom of the weight upper cover, a suspension line nose is arranged in the middle of the weight upper cover, the first suspension line passes through the suspension line nose, and a water retaining arc plate is arranged in the middle of the bottom of the weight upper cover.

[0006] Preferably, at least three lifting ears are evenly distributed on the spherical surface of the damping ball.

[0007] Preferably, the weight upper cover is threadedly connected to the top of the outer weight body, and a water stop pad is provided between the weight upper cover and the outer weight body.

[0008] Preferably, a threaded hole is provided through the middle of the weight upper cover, and the hanging wire nose is threadedly connected to the threaded hole.

[0009] Preferably, a through hole is provided in the middle of the suspension wire nose, and one end of the first suspension wire is knotted and the other end passes through the through hole.

[0010] Preferably, the water retaining arc plate is in an arc shape, and the water retaining arc plate is sealed at the bottom of the threaded hole and forms a receiving chamber with the bottom surface of the heavy hammer upper cover, and the knotted end of the first suspension line is received in the receiving chamber.

[0011] Preferably, a lifting ring whose number matches the lifting ears is arranged at the bottom of the weight upper cover, and the lifting ears and the lifting ring are flexibly connected by a second lifting wire.

[0012] In the utility model, the heavy hammer avoids the phenomenon that the heavy hammer swings for a long time due to the action of external force during the process of vertical alignment of component installation, thereby improving the alignment accuracy, reducing the operation time and improving the work efficiency.

[0013] The weight is designed as a hollow component. The hollow part of the outer weight body can accommodate the swing of the damping ball inside it. When the inside and outside vibrate at different frequencies, the damping ball can achieve the effect of mutual energy dissipation and reduce the swing amplitude of the weight. The second hanging wire connects the lifting ear with the lifting ring. When receiving external force, the damping ball can swing and interfere with the movement of the outer weight body through the second hanging wire, thereby playing the role of mutual energy dissipation. The weight cover is connected to the outer weight body through a thread. The weight cover can serve as a waterproof component of the hollow part and as a barrier between the damping ball and the outer weight body. The connecting component between the weight bodies also forms the outer shell of the weight together with the outer weight body; the hanging wire nose is connected to the weight cover by a thread. The hanging wire nose serves as a hollow component, and the first hanging wire passes through the through hole to suspend the weight; the water retaining arc plate is connected to the weight cover by electric welding. When the weight needs to sink underwater for operation, the continuous weld can prevent water from entering the hollow part through the through hole of the hanging wire nose 7; the water stop pad is used to increase the sealing effect between the weight cover and the outer weight body to prevent water from entering the hollow part and hindering the movement trajectory of the damping ball.
