Technical Field

[0001] The utility model relates to the technical field of construction engineering hoisting, in particular to a tower crane wall attachment conversion device. Background Art

[0002] Attaching a tower crane to a wall is an important safety measure in construction. Specifically, it refers to connecting part or all of the tower crane's components to the wall of a building to increase the tower crane's stability and safety so that the tower crane can rise as the building rises. Attaching a tower crane to a wall generally uses a wall attaching device, which includes a wall attaching frame and a wall attaching rod. The wall attaching frame is used to connect to the tower crane, and the wall attaching rod is used to connect the wall attaching frame to the wall.

[0003] The ideal design position of the tower crane is that one tower crane can cover the on-site working area. However, due to the restrictions on the requirements for attaching the tower crane to the wall, it is very easy to cause the tower crane to be unable to be installed at the ideal design position. At this time, a new tower crane is required to be added to meet the work requirements, which increases the construction cost. At present, an auxiliary device for attaching the tower crane to the wall has appeared (publication number CN220376210U), which provides a wall-attaching frame, which is fixedly connected to the wall through embedded parts, and the wall-attaching rod is connected to the wall by using the wall-attaching frame to meet the requirements of the wall-attaching angle, so that the tower crane can be placed at the ideal design position.

[0004] However, in the existing tower crane wall-mounted auxiliary device, all the connection points between the embedded parts and the wall are located in the same plane, which results in poor stability and uneven force, which may cause one of the connection points to be subjected to excessive force, increasing the risk of damage, and is extremely easy to deform, especially under lateral force or torque. In addition, the installation position of the auxiliary device is easily restricted by the exterior wall structure, making it difficult to use. Utility Model Content

[0023] In a typical implementation of the present invention, Figure 1-Figure 3 As shown, a tower crane wall-mounted conversion device is proposed, comprising: a connecting beam 1 and a supporting beam, the connecting beam 1 is a steel structure, which can be an H-shaped steel, a C-shaped steel or other structures, the connecting beam 1 is arranged horizontally for being fixedly arranged horizontally on the building wall and connected to the wall-mounted rod 13; one end of the supporting beam is fixedly connected to the building wall, and the other end is used to be fixedly connected to the connecting beam 1, so as to assist in supporting the connecting beam 1 and improve the installation stability of the connecting beam 1.

[0024] Specifically, a wall-mounted fixing plate 2 is fixed to one end of the connecting beam 1 by welding, and a plurality of bolt holes are opened on the wall-mounted fixing plate 2 so that the wall-mounted fixing plate 2 can be fixedly connected to the building wall by structures such as expansion bolts, thereby fixing the connecting beam 1 laterally on the building wall.

[0025] like Figure 1 As shown, a wall attaching rod connection unit 7 is fixedly provided on one side of the connecting beam 1, so as to be connected to the wall attaching rod 13 through the wall attaching rod connection unit 7. In this embodiment, the wall attaching rod connection unit 7 is an ear plate structure, and in other embodiments, it can also be other structures. The specific structure is determined according to the actual connection end structure of the wall attaching rod 13, and no excessive restrictions are made here.

[0026] A first connecting seat 3 is fixedly installed on the upper surface of the connecting beam 1, and the first connecting seat 3 is connected to the first supporting beam 4. A second connecting seat 5 is fixedly installed on the connecting beam 1 on the opposite side to the wall-attaching rod connecting unit 7, and the second connecting seat 5 is connected to the second supporting beam 6.

[0027] The first connecting seat 3 and the second connecting seat 5 have the same structure. The first connecting seat 3 and the second connecting seat 5 both include a first connecting plate and a first ear plate. The first ear plate is fixedly arranged on the first connecting plate. The first connecting plate is fixedly arranged on the connecting beam 1 by welding, bolting or the like.

[0028] The first support beam 4 and the second support beam 6 have the same structure. Figure 2 As shown, the first support beam 4 and the second support beam 6 both include a beam body 8 , and a connecting piece 9 is respectively provided at both ends of the beam body 8 to be connected to the building wall and the connecting beam 1 respectively.

[0029] Specifically, a connecting piece 9 is fixedly provided at one end of the beam body 8 for connecting with the building wall, and the connecting piece 9 includes a second connecting plate and two second ear plates. The second connecting plate is fixedly arranged at one end of the beam body 8 by welding or the like, and the two second ear plates are relatively fixedly arranged on the second connecting plate. The end of the beam body 8 fixedly connected with the connecting piece 9 is connected to the wall-attached embedded part 12 through the connecting piece 9;

[0030] The wall-attached embedded part 12 is used to be fixed on the building wall by expansion bolts. The wall-attached embedded part 12 includes a third connecting plate and a third ear plate. The third ear plate is fixedly arranged on the third connecting plate. The third ear plate is inserted between the two second ear plates. The third ear plate is connected to the second ear plates by locking bolts, so that the angle between the wall-attached embedded part 12 and the connecting part 9 can be changed as needed, thereby adjusting the angle of the beam body 8, and can be locked and fixed by using locking bolts.

[0031] A connecting piece 9 is installed at one end of the beam body 8 for connecting with the connecting beam 1. The beam body 8 can be axially retracted so that the axial position of the connecting piece 9 of the beam body 8 for connecting with the connecting beam 1 can be adjusted. In this embodiment, a screw rod 11 is threadedly connected to one end of the beam body 8 for connecting with the connecting beam 1, and a base 10 is threadedly connected to one end of the screw rod 11 away from the beam body 8. The connecting piece 9 is fixedly arranged on the base 10, so that the axial position of the connecting piece 9 can be adjusted by the screw rod 11, and the circumferential angle of the connecting piece 9 can be adjusted by the base 10 to ensure the connection between the connecting piece 9 and the connecting seat on the connecting beam 1;

[0035] It is understandable that, in order to improve the installation strength of the ear plate, a reinforcing structure such as a rib plate may be fixedly provided between the ear plate and the corresponding connecting plate.

[0036] The connecting beam 1, the first support beam 4 and the second support beam 6 form a conversion device, which is fixedly connected to the building wall by a three-point connection method, so that the force is more uniform, and the installation stability of the conversion device is effectively improved; the beam body 8 of the first support beam 4 and the second support beam 6 is a retractable structure, and can change the angle between the connecting beam 1 and the building wall, and can adapt to different exterior wall structures. It has strong overall adaptability, is easy to operate and use, and effectively reduces the cost of use.

[0037] It can be understood that in order to further improve the supporting stability of the connecting beam 1, a supporting beam can also be connected to the lower surface of the connecting beam 1.
