Description

Technical Field

[0001] This utility model relates to the field of tower crane machinery, specifically to a tower crane attachment clamp device. Background Technology

[0002] Tower cranes are commonly used equipment on construction sites, used for lifting various building materials and construction machinery, greatly improving construction efficiency. When the working height of a tower crane exceeds its independent height, the tower body must be attached. Attachment devices include attachment frames, adjustable attachment rods, and attachment bases. Conventional attachment bases are pre-embedded in the structure using embedded parts or installed by drilling into the structure and using through-wall bolts. However, when the external frame structure columns of a high-rise building are cylindrical, the attachment base cannot be installed using conventional methods. Therefore, to solve the above technical problems, it is necessary to provide a tower crane attachment clamp device to overcome the deficiencies in the existing technology. Utility Model Content

[0003] The present invention aims to provide a tower crane attachment clamp device to realize the installation connection between the tower crane attachment base and the cylindrical building outer frame structure.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a tower crane attachment clamp device, comprising two main plates, each main plate being a rectangular plate bent into a semi-circular arc shape, with connecting plates fixed radially on both outer ends of the main plates, and through holes provided on the connecting plates, and a first stiffening plate fixed between the connecting plates and the outer wall of the main plates, the first stiffening plate being a toothed plate with two arc-shaped edges, and two ear plates fixed axially side by side on the outer wall of the arc top of one of the main plates, with a second stiffening plate provided between the ear plates and the outer wall of the main plates, and a third stiffening plate connecting the roots of the two ear plates, each ear plate having through holes.

[0005] Preferably, as an improvement, each motherboard has a lifting lug on its outer wall at a distance of 45° from the end.

[0006] Preferably, as an improvement, the first stiffener extends from the connecting plate to the lifting lug.

[0007] Preferably, as an improvement, a third stiffener is provided on each side of the ear plate.

[0008] Preferably, as an improvement, the second stiffener is located at the top of the main plate arc on the outer side of the two ear plates.

[0009] Preferably, as an improvement, the connecting plate is provided with first stiffeners at both ends along the axial direction of the main plate.

[0010] The principle and advantages of this solution are as follows: In practical application, two semi-circular main plates are connected by bolts through the through holes in the end connecting plates, forming a circular clamp body. This allows the clamp body to fit tightly against the surface of the cylindrical building's outer frame structure, creating a stable tower crane attachment connection point. The clamp body is lifted using lifting lugs on the outer wall. The lugs are designed to ensure stability and ease of operation during lifting and installation. The connection part of the clamp body is structurally reinforced by a first stiffening plate. The shape of the first stiffening plate ensures a smooth overall appearance and prevents stress concentration areas. The first stiffening plate extends from the connecting plate to the lifting lugs, ensuring that the structural strength of the clamp body connection and lifting parts meets the tower crane attachment requirements. The ear plate is located at the arc apex of the main plate as the tower crane attachment connection point. The two ear plates are structurally reinforced by a third stiffening plate, and the ear plate is structurally reinforced with the main plate by a second stiffening plate, ensuring that the ear plate will not deform during use. The tower crane and the attachment tie rod can be stably and reliably connected to the ear plate. This utility model has a simple structure and is easy to install and use. It can be stably and reliably installed on the outer frame structure of a cylindrical building as the attachment connection point of a tower crane. It can provide stable and reliable installation support for the tower crane attachment rod, ensuring that the ultra-high tower crane can be stably attached to the outer frame of the cylindrical building.

[0013] The following detailed description illustrates the specific implementation method:

[0014] The reference numerals in the accompanying drawings include: main board 1, connecting plate 2, first stiffener 3, lifting lug 4, ear plate 5, second stiffener 6, and third stiffener 7.

[0015] The basic implementation examples are as follows: Figure 1 , Figure 2The diagram shows a tower crane attachment clamp device, comprising two main plates 1, each main plate being a rectangular plate curved into a semi-circular arc. Rectangular connecting plates 2 are radially welded to the outer ends of each main plate 1, and the connecting plates 2 have through holes. The connecting plates 2 at the ends of the two main plates 1 are connected by bolts through the through holes to form a circular clamp body. Lifting lugs 4 are welded to the outer wall of each main plate 1 at a distance of 45° from its end. First stiffening plates 3 are welded to both ends of each connecting plate 2 along the axial direction of the main plate 1. The first stiffening plates 3 are triangular toothed plates with two arc-shaped sides. The straight edges of the first stiffening plates 3 are attached to and welded to the connecting plates 2, and the inner arc-shaped edges of the first stiffening plates 3 are attached to and welded to the outer wall of the main plate 1. The first stiffening plates 3 extend from the connecting plates 2 to the lifting lugs 4. Two ear plates 5 are welded side-by-side to the outer wall of the arc top of one of the main plates 1, each ear plate 5 having two through holes. A second stiffening plate 6 is provided between the ear plates 5 and the outer wall of the main plate 1, located at the arc top of the main plate 1 outside the two ear plates 5. A third rib 7 is connected between the bases of the two ear plates 5, and there is one third rib 7 on each side of the ear plate 5.

[0016] The specific implementation process is as follows: During use, the two main plates 1 are hoisted to the predetermined height of the cylindrical building's outer frame structure using the lifting lugs 4. The two main plates 1 are then fastened together from both sides of the cylindrical building's outer frame structure. The bolts at the connecting plates 2 are tightened to ensure the two main plates 1 are tightly fitted to the surface of the cylindrical building's outer frame structure. Then, the lifting lugs 4 are released, completing the installation of the clamp on the cylindrical building's outer frame structure. For ultra-high tower crane attachment installation, the tower crane lifts the attachment arm or attachment rod to the clamp location. One end of the attachment rod is connected to the lugs 5 using bolts, and the other end of the attachment rod is connected to the tower crane's tower body using bolts, completing the attachment connection between the tower crane and the cylindrical building's outer frame structure.
