[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-3 In this embodiment of the utility model, an adjustable tower crane attachment frame includes two symmetrically arranged longitudinal rods 1. Both ends of the longitudinal rods 1 are integrally formed with outwardly protruding bent rods 2. The inside of the bent rods 2 is provided with a docking groove 3. An adjustable docking rod mechanism is inserted into the inner wall of the docking groove 3. A fixing mechanism for installing the adjustable docking mechanism is provided on the outside of the longitudinal rods 1.

[0018] In the embodiment, when the cumulative height of the standard sections constituting the tower crane exceeds a certain height, an attachment frame needs to be arranged outside the standard sections to maintain the stability of the cumulative standard sections. First, the telescopic support rod connected with the building is rotated, the telescopic support rod drives the longitudinal rods 1 to move through the rotating connector, until the two longitudinal rods 1 are attached to the outside of the standard sections. Then, the adjustable butt joint mechanism is butt jointed with the fixing mechanism outside the longitudinal rods 1, and the horizontal rods 4 are fixed through the fixing mechanism. At this time, the two longitudinal rods 1 and the horizontal rods 4 are clamped on the outside of the standard sections to improve the stability of the standard sections.

[0019] It should be noted that the bending rods 2 designed to be inclined have an opening larger at the end far away from the longitudinal rods 1, so that the adjustable butt joint rod mechanism can be conveniently inserted into the butt joint groove 3 at both ends, avoiding the problem that the adjustable butt joint rod mechanism cannot be smoothly inserted when the longitudinal rods 1 are attached to the outside of the standard sections. The length of the adjustable butt joint rod mechanism is in the shortest state.

[0020] Please refer to Figure 1 and Figure 3 The adjustable butt joint rod mechanism includes two horizontal rods 4 which are perpendicularly butt jointed with the longitudinal rods 1. The inside end of the horizontal rod 4 is provided with a receiving groove 10, and the inside wall of the receiving groove 10 is slidably connected with an adjusting rod 11. The end of the adjusting rod 11 far away from the horizontal rod 4 is welded with a butt joint seat 8, and the butt joint seat 8 is clamped to the inside of the butt joint groove 3.

[0021] In the embodiment, after the two longitudinal rods 1 are attached to the outside of the standard sections, the butt joint seat 8 fixedly connected to one end of the horizontal rod 4 is clamped into any butt joint groove 3. At this time, the other butt joint seat 8 is pulled or pushed, and the other butt joint seat 8 drives the adjusting rod 11 to slide in the receiving groove 10. At this time, the size of the standard section can be adjusted accordingly, and the two butt joint seats 8 are butt jointed with the fixing mechanism during the process of being inserted into the inside of the butt joint groove 3.

[0022] Please refer to Figure 2 The fixing mechanism includes a fixing seat 5 welded to the outside of the longitudinal rod 1. The end of the fixing seat 5 close to the butt joint groove 3 is welded with an insertion rod 6 extending towards the butt joint groove 3. The outer wall of the insertion rod 6 is formed with external threads 7. The inside of the butt joint seat 8 is provided with an insertion hole 12, and the diameter of the insertion hole 12 is equal to the diameter of the insertion rod 6.

[0023] In the embodiment, the butt joint seat 8 drives the insertion hole 12 to be butt jointed with the insertion rod 6, until the two horizontal rods 4 are in contact with the outside of the standard sections. At this time, the two horizontal rods 4 and the two longitudinal rods 1 cooperatively form a meandering structure to limit the standard section, thereby improving the stability of the standard section.

[0024] Please refer to Figure 2The outer wall of the plug-in rod 6 is screwed with a screw cap 9 for limiting the butt joint seat 8.

[0025] In the embodiment, after the plug-in rod 6 is effectively butted with the butt joint seat 8, the screw cap 9 is screwed with the outer thread 7, and is screwed tightly. After the screw cap 9 is screwed tightly, the installation is completed.

[0026] The above is only a preferred embodiment of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
