Detailed Implementation

[0019] 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.

[0020] A transition force transmission device for a conical tower crane standard section and a sand-dropping box, such as... Figures 1-4As shown, it includes a load-bearing column 1, which is a conical structure. A top plate 2 is connected to the upper side of the load-bearing column 1. A base plate 3 is provided at each of the four corners of the load-bearing column 1. Each base plate 3 has four mounting holes. Several reinforcing rods 4 are connected to the load-bearing column 1 for reinforcement. The reinforcing rods 4 and the load-bearing column 1 form a triangular structure with strong stability. A rotating disk 5 is rotatably connected to the top plate 2. A sliding block 6 is slidably connected to the rotating disk 5. The sliding block 6 is slidably connected to the top plate 2. A mounting frame 7 is connected between the two reinforcing rods 4 on the front and rear sides of the lower part. A pressure monitoring component 8 is installed on the mounting frame 7. A connecting rod 9 is connected between the pressure monitoring component 8 and the top plate 2. A connecting frame 10 is connected between every two adjacent reinforcing rods 4 in the middle. Two limit blocks are connected to each connecting frame 10. A rotating part 11 is rotatably connected to each connecting frame 10. Each rotating part 11 has four reserved holes.

[0021] It should be noted that the standard tower crane section is the main support and connection unit of the tower crane. It is usually a modular steel structure segment, which is assembled section by section by bolts or pins to form the vertical tower body of the tower crane. The drop sand box is a temporary support structure, which is filled with sand or a flowable medium. It is used to gradually release the load during construction to avoid deformation or damage caused by sudden unloading of the structure. The standard tower crane section and the drop sand box need to be connected by a transition force transmission device to solve key issues such as mechanical compatibility, dynamic stability and safety control.

[0022] During installation, the load-bearing column 1 is first installed on the standard tower crane section through the mounting holes on the base plate 3. The load-bearing column 1 adopts a tapered structure that is narrow at the top and wide at the bottom, so that the axial pressure is evenly distributed along the height direction, reducing local stress concentration. The reinforcing rod 4 forms multiple triangular structures with the load-bearing column 1, which can improve the overall bending stiffness of the load-bearing column 1. The unloading sand box is connected to the top plate 2, thereby realizing the transition force transmission effect between the standard tower crane section and the unloading sand box. When the position of the unloading sand box is offset and needs to be finely adjusted, the sliding block 6 can be slid to allow the rotating disk 5 to rotate as needed, thereby finely adjusting the position of the unloading sand box. Then, the sliding block 6 is slid to lock the rotating disk 5 again.

[0023] After installation, the pressure on the top plate 2 is transmitted to the pressure monitoring component 8 through the connecting rod 9. The pressure monitoring component 8 can statically monitor the stress state of the top plate 2 and reflect the long-term load trend through frequency changes. At the same time, it samples dynamic stress waves at high frequency and transmits the data to the monitoring platform, which makes it convenient for operators to monitor the stress state in real time and understand the degree of stress transmission, which is beneficial to construction safety. When it is necessary to install sand box guide pipe, temporary support frame or maintenance platform, the load-bearing column 1 can be extended by flipping the rotating part 11 outward and installing the extension material through the reserved hole, which is more convenient for operators.

[0024] It should be understood that the above description is for illustrative purposes only and is not intended to limit the present invention. Those skilled in the art will understand that variations of the present invention will be included within the scope of the claims herein.
