Description

Technical Field

[0001] This utility model belongs to the field of construction machinery technology, specifically a tower crane body reinforcement structure. Background Technology

[0002] In the construction industry, tower cranes, as crucial vertical transportation equipment, directly impact construction safety and efficiency due to the structural strength and stability of their tower bodies. Currently, most tower cranes on the market are constructed using standard section splicing. While this meets basic load-bearing requirements, as construction height and load increase, the limitations of traditional tower structures in terms of bending resistance, torsion resistance, and overall rigidity are becoming increasingly apparent. Furthermore, existing reinforcement measures often involve increasing material usage or altering cross-sectional shapes, which not only increases manufacturing costs but may also lead to an increase in the overall weight of the tower, thus placing higher demands on foundation support.

[0003] Therefore, we have made improvements to this and proposed a flatness testing device for fireproof glass processing. Utility Model Content

[0004] The purpose of this utility model is to solve the current limitations of tower crane tower bodies in terms of bending resistance, torsion resistance and overall rigidity, while avoiding the shortcomings of high manufacturing costs and increased overall weight caused by the traditional method of strengthening by increasing material usage or changing cross-sectional shape.

[0005] To achieve the aforementioned objectives and address the aforementioned problems, this utility model provides a tower crane body reinforcement structure, comprising a tower body main body and reinforcement components disposed on the tower body main body. The reinforcement components include a support frame, a connecting plate, and an adjustment mechanism. The support frame is fixedly installed on the outer side of the tower body main body. The connecting plate is bolted to the support frame. The adjustment mechanism is disposed inside the support frame and cooperates with the connecting plate to dynamically adjust the rigidity of the tower body main body.

[0006] The support frame includes two parallel support beams connected by several crossbeams to form a frame structure. Each support beam has an inner groove extending along its length to accommodate the sliding components of the adjustment mechanism. The connecting plate is embedded at both ends into the grooves of the two support beams and fixedly connected to them with bolts. A through hole is provided in the center of the connecting plate for mounting the core components of the adjustment mechanism.

[0007] The adjusting mechanism includes an adjusting rod, a sleeve, and an elastic element. One end of the adjusting rod passes through a through hole in the connecting plate and is threadedly connected to the sleeve, while the other end contacts the outer wall of the tower body. A rotating handle is provided on the outer side of the sleeve, which drives the sleeve to rotate, thereby causing the adjusting rod to move axially. The elastic element is disposed inside the sleeve, with one end contacting the end of the adjusting rod and the other end contacting the inner wall of the sleeve, providing a cushioning effect and maintaining the stability of the adjusting rod.

[0008] As a preferred embodiment of this application, the outer side of the support beam is provided with reinforcing ribs, which are arranged along the length of the support beam and welded to the crossbeam. The reinforcing ribs enhance the overall strength of the support frame and reduce deformation caused by external loads.

[0009] As a preferred embodiment of this application, guide blocks are provided on both sides of the connecting plate. The guide blocks are embedded in the grooves of the support beam and fit tightly against the inner wall of the grooves. The guide blocks ensure the smooth movement of the connecting plate within the grooves and prevent the connecting plate from shifting during adjustment.

[0010] As a preferred technical solution of this application, the end of the adjusting rod is provided with a rubber pad, which contacts the outer wall of the tower body. The rubber pad reduces the friction between the adjusting rod and the tower body, while avoiding damage to the surface of the tower body due to direct contact.

[0011] As a preferred embodiment of this application, the sleeve is provided with a locating pin inside, which penetrates the side wall of the sleeve and contacts the outer surface of the adjusting rod. The locating pin is used to limit the rotation of the adjusting rod, ensuring that the adjusting rod moves only axially when the sleeve rotates.

[0012] As a preferred technical solution of this application, the elastic element is a helical spring, and the two ends of the helical spring are welded to the end of the adjusting rod and the inner wall of the sleeve, respectively. The helical spring provides a stable buffering force and is easy to disassemble and replace.

[0013] As a preferred technical solution of this application, the top of the support frame is provided with a mounting base, which is used to connect with other components of the tower crane. The mounting base facilitates the integration of the reinforcement components with other tower crane parts, improving the overall installation efficiency of the tower crane.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: In the scheme of this application: The support frame, connecting plate, and adjustment mechanism enable dynamic adjustment of the tower crane's rigidity. The support frame, with its frame structure, enhances the tower's resistance to bending and torsion. Simultaneously, the connecting plate and adjustment mechanism work together to precisely adjust the tower's rigidity according to actual needs. The adjustment rod in the adjustment mechanism moves axially through the rotation of the sleeve, applying preload to the tower and further improving its overall stability. Furthermore, the elastic element provides a buffer, reducing the impact of external load fluctuations on the tower. This invention, through optimized structural design, significantly improves the rigidity and stability of the tower crane without increasing material usage, solving the problems of high manufacturing costs and increased overall weight associated with traditional reinforcement measures in existing technologies.

[0021] This utility model relates to a tower crane body reinforcement structure, which achieves dynamic adjustment of the tower crane body rigidity through the coordinated use of a support frame, connecting plate, and adjustment mechanism. It avoids the problems of high manufacturing costs and increased overall weight caused by increasing material usage or changing cross-sectional shape in traditional reinforcement methods. The following is in conjunction with the appendix... Figures 1 to 5 The accompanying drawings and reference numerals will provide a detailed description of the specific embodiments of this utility model.

[0022] like Figure 1As shown, the overall structure of this utility model includes a tower body 1 and a reinforcing component disposed on the outside of the tower body 1. The reinforcing component consists of a support frame 2, a connecting plate 5, and an adjustment mechanism 6. The support frame 2 is fixedly installed on the outside of the tower body 1 to provide the main support function; the connecting plate 5 is connected to the support frame 2 by bolts and is embedded in the sliding groove 10 on the inner side of the support frame 2; the adjustment mechanism 6 is disposed inside the support frame 2 and works in conjunction with the connecting plate 5 to achieve dynamic adjustment of the rigidity of the tower body 1.

[0023] like Figure 3 and Figure 4 As shown, the support frame 2 consists of two parallel support beams 3 and several crossbeams 4, forming a frame structure. The length of the support beams 3 extends along the height of the tower body 1, while the crossbeams 4 are perpendicular to the support beams 3 and welded between them to enhance the overall stability of the support frame 2. To improve the bending and torsional resistance of the support frame 2, each support beam 3 is provided with a reinforcing rib 11 on its outer side. The reinforcing ribs 11 are arranged along the length of the support beam 3 and welded to the crossbeams 4. The presence of the reinforcing ribs 11 not only enhances the overall strength of the support frame 2 but also reduces deformation caused by external loads. In addition, the top of the support frame 2 is provided with a mounting base 15, which is used to connect with other components of the tower crane, facilitating the integration of the reinforcement assembly with other tower crane components.

[0024] like Figure 3 and Figure 4 As shown, the two ends of the connecting plate 5 are respectively embedded in the sliding grooves 10 inside the two support beams 3. The sliding grooves 10 extend along the length of the support beams 3, providing a guide path for the movement of the connecting plate 5. To ensure the smooth movement of the connecting plate 5 within the sliding grooves 10, guide blocks 12 are provided on both sides of the connecting plate 5. The guide blocks 12 are embedded in the sliding grooves 10 and fit tightly against the inner wall of the sliding grooves 10. The design of the guide blocks 12 prevents the connecting plate 5 from shifting during adjustment, thereby ensuring the accuracy of the adjustment. A through hole is provided in the middle of the connecting plate 5 for installing the core components of the adjustment mechanism 6.

[0025] like Figure 1 and Figure 5As shown, the adjusting mechanism 6 includes an adjusting rod 7, a sleeve 8, an elastic element 9, and a positioning pin 14. One end of the adjusting rod 7 passes through the through hole of the connecting plate 5 and is threadedly connected to the sleeve 8, while the other end contacts the outer wall of the tower body 1. A rotating handle is provided on the outer side of the sleeve 8, which is used to drive the sleeve 8 to rotate. When the sleeve 8 rotates, the adjusting rod 7 moves axially due to the threaded connection, thereby applying a preload to the tower body 1. To reduce friction between the adjusting rod 7 and the tower body 1 and to protect the surface of the tower body 1, a rubber pad 13 is provided at the end of the adjusting rod 7, which directly contacts the outer wall of the tower body 1. The elastic element 9 is located inside the sleeve 8, with one end contacting the end of the adjusting rod 7 and the other end contacting the inner wall of the sleeve 8. The elastic element 9 is in the form of a helical spring, with both ends of the helical spring welded to the end of the adjusting rod 7 and the inner wall of the sleeve 8, respectively. The elastic element 9 provides a buffering effect for the adjusting rod 7, reducing the impact on the tower body 1 caused by external load fluctuations. In addition, the sleeve 8 is provided with a positioning pin 14 inside. The positioning pin 14 passes through the side wall of the sleeve 8 and contacts the outer surface of the adjusting rod 7. It is used to limit the rotation of the adjusting rod 7 and ensure that the adjusting rod 7 moves only axially when the sleeve 8 rotates.

[0026] like Figure 5 As shown, in practical applications, the adjusting mechanism 6 drives the sleeve 8 to rotate via a rotating handle, causing the adjusting rod 7 to move axially and apply a preload to the tower body 1. The magnitude of the preload can be adjusted according to actual needs, thereby achieving dynamic adjustment of the rigidity of the tower body 1. For example, when the tower crane is subjected to a large external load, the preload of the adjusting rod 7 can be increased by rotating the handle to further improve the overall stability of the tower body 1; while when the external load is small, the preload can be appropriately reduced to reduce the pressure on the tower body 1. This process is achieved through the precise control of the adjusting mechanism 6.

[0027] The working principle of the support frame 2, connecting plate 5, and adjusting mechanism 6 is as follows: When it is necessary to adjust the rigidity of the tower body 1, the operator first drives the sleeve 8 to rotate by rotating the handle. The rotation of the sleeve 8 drives the adjusting rod 7 to move axially. The movement of the adjusting rod 7 is transmitted to the support frame 2 through the connecting plate 5, thereby applying a certain preload to the tower body 1 by the support frame 2. The magnitude of the preload depends on the movement distance of the adjusting rod 7, which can be precisely controlled by the number of turns of the rotating handle. During the adjustment process, the movement of the connecting plate 5 in the slide groove 10 is guided by the guide block 12, ensuring the smoothness and accuracy of the adjustment. At the same time, the buffering effect provided by the elastic element 9 reduces the impact of external load fluctuations on the tower body 1, further improving the overall stability of the tower crane.

[0028] The reinforced structure of this invention has wide application value in actual construction scenarios. For example, in the construction of high-rise buildings, tower cranes need to withstand large wind loads and lifting loads. In this case, the preload can be increased by adjusting the mechanism 6, thereby improving the bending and torsional resistance of the main tower body 1. Under light-load construction conditions, the pressure on the main tower body 1 can be reduced by decreasing the preload, avoiding unnecessary material waste. In addition, since the reinforced structure of this invention does not require increasing the amount of material or changing the cross-sectional shape of the main tower body 1, it has significant advantages in terms of manufacturing cost and overall weight.

[0029] This invention solves the problems of high manufacturing costs and increased overall weight caused by traditional reinforcement measures in the prior art by optimizing the structural design, while realizing dynamic adjustment of the tower crane's rigidity. Through the frame structure of the support frame 2, the guiding design of the connecting plate 5, and the precise control of the adjustment mechanism 6, this invention significantly improves the rigidity and stability of the tower crane's body without increasing the amount of material used.

[0030] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the specific implementation principle of this utility model is provided in conjunction with a specific application scenario.

[0031] In actual construction scenarios, tower cranes typically need to withstand significant wind loads and lifting loads. For example, in high-rise building construction, the main body 1 of the tower crane needs to have sufficient bending and torsional resistance to ensure construction safety. In this case, operators can dynamically adjust the rigidity of the tower body using the adjustment mechanism 6 to meet the needs of different working conditions.

[0032] First, the operator rotates the handle on the outside of the sleeve 8 in the adjusting mechanism 6, causing the sleeve 8 to rotate. Since the adjusting rod 7 and the sleeve 8 are threaded together, the rotation of the sleeve 8 drives the adjusting rod 7 to move axially. One end of the adjusting rod 7 contacts the outer wall of the tower body 1 via a rubber pad 13. When the adjusting rod 7 moves outward axially, it applies a preload to the tower body 1. This preload is transmitted to the support frame 2 through the connecting plate 5 and ultimately acts on the outside of the tower body 1, thereby enhancing the overall rigidity of the tower. During this process, both ends of the connecting plate 5 are embedded in the grooves 10 inside the support beam 3 and guided smoothly by the guide block 12, ensuring the accuracy and stability of the adjustment process.

[0033] Secondly, when external loads fluctuate significantly, the elastic element 9 in the adjusting mechanism 6 acts as a buffer. The elastic element 9 is located inside the sleeve 8, with one end contacting the end of the adjusting rod 7 and the other end contacting the inner wall of the sleeve 8. When the external load suddenly increases, the elastic element 9 can absorb some of the impact force, preventing excessive stress from acting directly on the tower body 1, thereby reducing the risk of deformation caused by instantaneous load changes. Furthermore, the positioning pin 14 penetrates the side wall of the sleeve 8 and contacts the outer surface of the adjusting rod 7, restricting the rotation of the adjusting rod 7 and ensuring that it moves only axially, further improving the reliability of the adjustment.

[0034] Under light-load construction conditions, operators can rotate the handle of sleeve 8 in the opposite direction to move the adjusting rod 7 axially inward, thereby reducing the preload on the tower body 1. This flexible adjustment method not only reduces the pressure on the tower body 1 but also avoids unnecessary material waste and extends the service life of the tower crane.

[0035] The design of the support frame 2 also plays a crucial role in enhancing the rigidity of the tower body. The support frame 2 consists of two parallel support beams 3 and several crossbeams 4, forming a frame structure. Each support beam 3 has a reinforcing rib 11 on its outer side, which is arranged along the length of the support beam 3 and welded to the crossbeam 4. This design significantly enhances the overall strength of the support frame 2 while reducing deformation caused by external loads. In practical applications, the support frame 2 is integrated with other tower crane components via mounting bases 15, facilitating overall installation and maintenance.

[0036] As can be seen from the above steps, the reinforced structure of this utility model can dynamically adjust the rigidity of the tower crane body according to actual construction needs. For example, in high-rise building construction, when the tower crane needs to withstand large wind loads and lifting loads, operators can increase the preload of the adjusting rod 7 to improve the bending and torsional resistance of the main body 1; while under light-load construction conditions, the pressure on the main body 1 can be reduced by decreasing the preload, thus avoiding material waste. In addition, since this utility model does not require increasing material usage or changing the cross-sectional shape of the main body 1, it has significant advantages in terms of manufacturing cost and overall weight.

[0037] In summary, this invention solves the problems of high manufacturing costs and increased overall weight caused by traditional reinforcement measures in the prior art by optimizing the structural design, while realizing dynamic adjustment of the tower crane's rigidity. Through the frame structure of the support frame 2, the guiding design of the connecting plate 5, and the precise control of the adjustment mechanism 6, this invention significantly improves the rigidity and stability of the tower crane's body without increasing the amount of material used.
