Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a safety structure for preventing tower crane sections from falling off. Background Technology

[0002] Tower cranes, also known as "tower hoists," are the most commonly used lifting equipment on construction sites. They are constructed by extending (in height) section by section (referred to as "standard sections") to lift construction materials such as steel bars, timber, concrete, and steel pipes. Tower cranes are an indispensable piece of equipment on construction sites. The function of the tower crane tip is to bear the upper load transmitted from the boom ropes and counterweight boom ropes, and then directly transfer the load to the tower body structure through the slewing tower, turntable, and bearing base. Self-erecting tower cranes come in various types, including truncated cone type, forward- or backward-leaning truncated cone type, A-frame type, and inclined brace type.

[0003] Tower crane sections are standard sections in tower cranes and are an important part of the main structure of the tower crane. Tower crane sections are stacked layer by layer, and the connection structure between each tower crane section is particularly important, directly affecting the safety of the tower crane. The existing standard sections are not stable enough, and long-term use can easily lead to the risk of falling off, which greatly reduces the overall safety and reliability of use.

[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 Figure 1-3This utility model provides a technical solution: a tower crane section anti-falling safety structure, including a tower crane section bottom 6, a tower crane section top 8 at the bottom of the tower crane section bottom 6, and a connecting protrusion 12 on one side surface of the tower crane section top 8, which allows the tower crane sections to be drilled in an alternating manner for bolt penetration and overall connection. First bolts 2 are penetrated through the surfaces of both the connecting protrusion 12 and the tower crane section bottom 6. A square support block 3 is located below the first bolt 2, and second bolts 4 are penetrated through the surfaces of both the connecting protrusion 12 and the tower crane section bottom 6 below the square support block 3. By setting connecting parts at the four corners of the tower crane standard section connection, the tower crane standard section can be effectively reinforced, effectively preventing long-term damage to the tower crane standard section. In case of detachment during use, this design effectively strengthens the stability of the connection between tower crane sections, further enhancing the safety of tower crane operation. The surfaces of the first bolt 2, the square support block 3, and the second bolt 4 are all longitudinally perforated with positioning pins 5, which can connect the first bolt 2, the square support block 3, and the second bolt 4 to form an integrated unit. This allows the standard tower crane sections to be connected in series for effective support and reinforcement. The surfaces of the first bolt 2, the square support block 3, and the second bolt 4 are all correspondingly provided with positioning holes 9 for insertion into the positioning pins 5. The top of the positioning pin 5 is integrally formed with an anti-detachment cap 1, which can act as a top block to prevent the positioning pin 5 from sliding directly down the positioning hole 9 and falling to the outside.

[0018] The bottom side surface of the positioning pin 5 is provided with a snap-fit ​​hole 11, and a snap-fit ​​pin 10 is inserted into the inner side of the snap-fit ​​hole 11. This can prevent the positioning pin 5 from falling off after long-term use and can effectively lock the bottom. A connecting node 7 is formed between the bottom 6 and the top 8 of the tower crane section, which can combine and support the upper and lower parts of the tower crane section, making the support tighter and more secure. The first bolt 2 and the second bolt 4 are arranged perpendicularly to each other. The shape of the connecting protrusion 12 is two plates that are spliced ​​vertically to each other. It can effectively fit tightly with the inner side of the four corners of the tower crane section, avoiding a large number of gaps that would prevent the connector from being installed and supported effectively.

[0019] Working principle: When reinforcement of tower crane standard sections is required, the top 8 and bottom 6 of the tower crane section can be spliced ​​together so that the connecting protrusion 12 can be parallel and fitted to the upper surface of the bottom 6. Then, holes are drilled at corresponding positions on the top 8 and the connecting protrusion 12. The first bolt 2, the square support block 3, and the second bolt 4 are installed sequentially from top to bottom through the drilled holes. Positioning holes 9 are made at the top of the first bolt 2, the square support block 3, and the second bolt 4. Positioning pins 5 are inserted sequentially from top to bottom through the positioning holes 9 at the top of the first bolt 2, the square support block 3, and the second bolt 4. Finally, the snap-fit ​​pin 10 is inserted into the snap-fit ​​hole 11. During daily use, by setting connectors at the four corners of the tower crane standard section connection, the tower crane standard section can be effectively reinforced, which can effectively prevent the tower crane standard section from falling off during long-term use, and can greatly enhance the stability of the connection between tower crane sections, further improving the safety of tower crane use.
