Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering machinery and equipment, in particular to a tower crane supporting climbing device suitable for weak structures. Background Art

[0002] Tower cranes include external tower cranes and ground-mounted external tower cranes. When installing external tower cranes, embedded parts and external hanging devices are installed on the shear wall to make the tower crane structure climb along with the construction surface, thereby reducing the influence of the tower body, resulting in a large number of reserved holes in the building structure, so that the building under construction can be formed in one go. When the floor height is too high, there is no shear wall in the high-rise building, only a frame-column structure. The structural strength of the frame-column structure cannot meet the needs of the climbing reaction force of the external tower crane, and the external tower crane cannot climb smoothly.

[0003] The ground-mounted external tower crane is installed by setting a steel platform on the lower shear wall and attaching the tower crane to the upper weak structure to achieve the jacking and sectioning of the tower crane. However, for the construction of super-high-rise structures, there are many reserved holes for the ground-mounted external tower crane, and there will be a large number of reserved structures in the basement and the main building during the installation and demolition of the ground-mounted external tower crane. The pressure of filling the holes in the later stage is high, there are many safety hazards, the risk of water leakage is large, and it is difficult to insert the fine decoration construction in advance, which affects the construction progress. In addition, setting an attached wall on the upper weak structure will affect the installation of the super-high-rise outer frame steel structure. The ground-mounted external tower crane needs to install a sleeve frame to achieve jacking and sectioning. The investment cost of the ground-mounted external tower crane is high, and there are many floors with reserved holes, which delays the closure time of the super-high-rise upper structure and the insertion construction node of the second structure fine decoration electromechanical is delayed, affecting the construction progress.

The adjustable connecting member 4 structure can be adjusted in length according to the floor height parameters of the weak structure so that the first section of the adjustable connecting member 4 is fixedly connected to the lower beams and columns of the weak structure, thereby avoiding pre-buried installation on the weak structure, avoiding damage to the weak structure, improving the integrity of the structure, and improving the reliability and safety of the overall building.

[0027] In some embodiments of the utility model, the supporting base 2 includes a first support rod 21 and a second support rod 22, one end of the first support rod 21 and the second support rod 22 are connected to the wall 1, and the first support rod 21 and the second support rod 22 are provided with a first connecting base 23 and a second connecting base 24 at the end away from the wall 1, and the two first connecting bases 23 are respectively arranged on two side surfaces of the first support rod 21 and the second support rod 22 that are away from each other, and two horizontal connecting members 3 are provided, and are fixedly connected to the two first connecting bases 23 respectively, and two second connecting bases 24 are respectively provided at the bottom of the first support rod 21 and the second support rod 22, and two adjustable connecting members 4 are provided, and are fixedly connected to the two second connecting bases 24 respectively.

The horizontal connecting rod 28 is perpendicular to the first support rod 21 / the second support rod 22. There are at least two horizontal connecting rods 28, which are arranged at intervals.

[0030] Specifically, the horizontal connecting rod 28 is used to connect the first support rod 21 and the second support rod 22. Since the first support rod 21 and the second support rod 22 are arranged parallel to each other, the horizontal connecting rod 28 provides a supporting force in a direction perpendicular to the first support rod 21 and the second support rod 22, so that the supporting force is balanced with the horizontal component of the pulling force provided by the horizontal connecting member 3 to ensure the stability of the structure.

[0031] It is understandable that multiple horizontal connecting rods 28 can be provided, at least two, and the two horizontal connecting rods 28 are respectively located at both ends of the first support rod 21 and the second support rod 22 to form a rectangular frame to ensure the stability of the structure and be suitable for installation in the tower body.

[0032] In some embodiments of the utility model, the supporting base 2 also includes a load-bearing member 27, the two ends of the load-bearing member 27 are respectively fixedly connected to the upper end surfaces of the first support rod 21 and the second support rod 22, the load-bearing member 27 and the horizontal connecting rod 28 are parallel to each other, and the load-bearing member 27 is suitable for being fixedly connected to the tower body to provide supporting force for the tower body.

[0035] Specifically, the first limiting base 25 and the second limiting base 26 can slide along the length direction of the first support rod 21 and the second support rod 22 respectively, so as to be suitable for adjusting the installation position of the load-bearing member 27. The installation positions of the first limiting base 25 and the second limiting base 26 are determined according to the size of the tower body, so as to determine the fixed position of the load-bearing member 27. It can be understood that two load-bearing members 27 are provided, and two first limiting bases 25 and second limiting bases 26 are provided, and the first limiting base 25 is arranged at intervals along the length direction of the first support rod 21, and the second limiting base 26 is arranged at intervals along the length direction of the second support rod 22.

[0037] Specifically, a locking structure 271 is provided on the load-bearing member 27, and a fixed frame is sleeved on the tower body to fix the tower body. The fixed frame is fixedly connected to the locking structure 271, so that the tower body is fixedly connected to the load-bearing member 27 to achieve the limitation of the tower body.

[0038] In some embodiments of the utility model, the adjustable connecting member 4, the wall 1 and the first support rod 21 / the second support rod 22 enclose a triangular structure located in a vertical plane; the horizontal connecting member 3, the wall 1 and the first support rod 21 / the second support rod 22 enclose a triangular structure located in a horizontal plane.

[0039] Specifically, the triangular structure is a stable structure, which is formed by enclosing the adjustable connector 4, the wall 1 and the first support rod 21 / the second support rod 22 to form a triangular structure located in a vertical plane; and the horizontal connector 3, the wall 1 and the first support rod 21 / the second support rod 22 to form a triangular structure located in a horizontal plane, so as to ensure force balance and improve structural stability.

The length of the second connecting section 42 is adjustable, and the two ends of the second connecting section 42 are fixedly connected to the third connecting section 43 and the first connecting section 41 respectively.

The overall length of the adjustable connecting member 4 is adjusted by selecting the length of the second connecting section 42. Since the adjustable connecting member 4 is used to support force and the force is large, the use of sliding adjustment may easily lead to structural instability. The first connecting section 41, the second connecting section 42 and the third connecting section 43 are fixedly connected in sequence to ensure the stability of the structural connection and provide a stable supporting force for the supporting base 2.
