Description

Technical Field

[0001] The present application relates to the technical field of tower cranes, and in particular to a tower crane anchoring device for prefabricated exterior walls without requiring opening of holes. Background Art

[0002] Tower crane is also called tower crane, which originated in Western Europe. It is a rotating crane with a boom mounted on the top of a tall tower. It has a large working space and is mainly used for vertical and horizontal transportation of materials and installation of building components in house construction. It consists of three parts: metal structure, working mechanism and electrical system. The metal structure includes the tower, boom and base. The working mechanism has four parts: lifting, luffing, slewing and traveling. The electrical system includes motors, controllers, distribution cabinets, connecting lines, signals and lighting devices, etc.

[0003] Most of the existing tower cranes lift and move objects by hooks or ropes. When prefabricated exterior wall panels need to be hoisted, holes need to be drilled in the exterior wall panels for hoisting, which may cause damage to the exterior wall panels. Utility Model Content

[0004] The purpose of the utility model is to solve or at least alleviate the problem that most of the existing tower cranes lift and move objects by hooks or ropes, and when prefabricated exterior wall panels need to be lifted, holes need to be made in the exterior wall panels for lifting, which may cause damage to the exterior wall panels.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A tower crane anchoring device for prefabricated exterior walls without opening holes comprises a fixing plate, the fixing plate is provided with a connecting assembly for fixing the exterior wall panel, the connecting assembly comprises four electric suction cups slidably arranged on the lower surface of the fixing plate through a sliding assembly, a group of fixing rods are provided at both ends of the upper surface of the fixing plate, each group of the fixing rods penetrates the fixing plate and forms a sliding connection, each group of the fixing rods located on the upper surface of the fixing plate is threadedly connected with a nut, the bottom ends of the side walls on the opposite sides of the two groups of the fixing rods are provided with support rods, one end of the support rods penetrates the fixing rods and forms a threaded connection.

[0007] By adopting the above technical solution, when in use, the exterior wall panel is placed flat, the exterior wall panel is adsorbed by an electric suction cup, and then the exterior wall panel is lifted, and then the fixing rod is slid on the fixing plate so that the bottom end of the fixing rod is located below the horizontal plane of the exterior wall panel, and then the support rod is rotated to bring one end of the support rod closer to each other and extend it to the bottom of the exterior wall panel to abut against the lower surface of the exterior wall panel, and then the nut is rotated to fit the nut with the upper surface of the fixing plate, so that the fixing rod cannot slide, and the exterior wall panel is lifted, which avoids the need to drill holes in the exterior wall panel for lifting it, which may cause damage to the exterior wall panel.

[0008] Optionally, two ends of the upper surface of the fixing plate are provided with parallel through grooves, and the two groups of fixing rods are respectively arranged in the through grooves.

[0009] By adopting the above technical solution, the fixing rods can be made to slide in the through grooves, and the distance between the fixing rods can be adjusted, so as to facilitate the lifting of exterior wall panels of different sizes.

[0010] Optionally, the top ends of the fixing rods are fixedly connected to limiting plates.

[0011] By adopting the above technical solution, the limiting plate can prevent the nut from sliding out from the top end of the fixing rod, causing the fixing rod to fall off the fixing plate.

[0012] Optionally, the sliding assembly includes four T-shaped slots opened on the lower surface of the fixed plate, the four T-shaped slots are cross-shaped and are all slidably connected with a T-shaped slider, and one end of the T-shaped slider away from the T-shaped slot is fixedly connected to the electric suction cup.

[0013] By adopting the above technical solution, the distance between the four electric suction cups can be adjusted by sliding the T-shaped slider in the T-shaped slide groove, so as to facilitate the adsorption of exterior wall panels of different sizes.

[0014] Optionally, one end of the T-shaped slide groove is provided with an opening.

[0015] By adopting the above technical solution, the T-shaped slider can be slid out of the T-shaped slide groove through the opening, so that the electric suction cup can be easily replaced and maintained.

[0016] Optionally, support plates are inserted into the ends of the support rods that are close to each other.

[0017] By adopting the above technical solution, the support plate can increase the contact area with the exterior wall panel to prevent the exterior wall panel from accidentally detaching from the electric suction cup and causing the weight to press on the support rod, thereby causing indentations on the exterior wall panel and affecting the appearance.

[0018] Optionally, a connecting ring is fixedly connected to the upper surface of the fixing plate.

[0019] By adopting the above technical solution, the fixing plate can be conveniently connected to the hook or rope of the tower crane through the connecting ring.

[0020] Optionally, the T-shaped slide groove is slidably connected to a limit rod in a side wall on one side of the opening, and one end of the limit rod is plugged into the other side wall of the T-shaped slide groove.

[0021] By adopting the above technical solution, when the electric suction cup is not working, the opening can be blocked by the limit rod to prevent the T-shaped slider from sliding in the T-shaped slide groove and sliding out of the opening during transportation, causing the electric suction cup to be lost.

[0022] In summary, the beneficial effects of this application are as follows:

[0023] 1. The present application is provided with coordination between structures such as an electric suction cup, a fixing rod and a supporting rod. When in use, the exterior wall panel is laid flat, the exterior wall panel is adsorbed by the electric suction cup, and then the exterior wall panel is lifted. Then the fixing rod is slid on the fixing plate so that the bottom end of the fixing rod is located below the horizontal plane of the exterior wall panel. Then the supporting rod is rotated to bring one end of the supporting rod closer to each other and extend it below the exterior wall panel to abut against the lower surface of the exterior wall panel. Then the nut is rotated to fit the nut with the upper surface of the fixing plate so that the fixing rod cannot slide and the exterior wall panel is lifted, thus avoiding the problem of damage to the exterior wall panel caused by drilling holes in the exterior wall panel for lifting.

[0024] 2. By sliding the T-shaped slider in the T-shaped slot, the distance between the four electric suction cups can be adjusted to facilitate the adsorption of exterior wall panels of different sizes. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Reference Figure 1 Parallel through grooves 6 are provided at both ends of the upper surface of the fixing plate 1, and two sets of fixing rods 3 are respectively arranged in the through grooves 6, so that the fixing rods 3 can slide in the through grooves 6 and the distance between the fixing rods 3 can be adjusted to facilitate the lifting of exterior wall panels of different sizes.

[0033] Reference Figure 1 The top of the fixing rod 3 is fixedly connected to a limiting plate 7, and the limiting plate 7 can prevent the nut 4 from slipping out from the top of the fixing rod 3, causing the fixing rod 3 to fall off the fixing plate 1.

[0034] Reference Figure 2 The sliding assembly includes four T-shaped slots 8 opened on the lower surface of the fixed plate 1. The four T-shaped slots 8 are cross-shaped and are all slidably connected with a T-shaped slider 9.
