Description

Technical Field

[0001] The utility model belongs to the technical field of hoisting equipment, and specifically relates to a fixed pulley installation structure for a cold rolling overhead traveling crane. Background Art

[0002] During the operation of goods by the overhead traveling crane of the cold rolling section, fixed pulleys are mostly required to be used for lifting, transporting, and guiding heavy objects, which can effectively change the direction of force and reduce friction, thereby improving work efficiency and safety. By using fixed pulleys, greater lifting force can be achieved, the labor intensity of operators can be reduced, and tasks can be completed efficiently and safely in complex working environments.

[0003] In the prior art, the weight of the heavy object lifted by the crane is heavy. Once the center of gravity of the heavy object shifts, the mounting frame will bear a great force, and the connecting device between the pulley shaft and the mounting frame often bears a large load, which easily increases the risk of equipment damage and further leads to safety accidents. Secondly, the existing installation structure has high precision requirements and a cumbersome installation process, resulting in difficulties in disassembly and maintenance. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a fixed pulley installation structure for a cold rolling overhead traveling crane to solve at least one of the problems and defects mentioned in the above background art.

[0005] A fixed pulley installation structure for a cold rolling overhead traveling crane is provided, which includes two mounting frames. An installation rod body is arranged below the two mounting frames. Limit shaft plates are arranged on both of the two installation rod bodies. A rotating shaft is detachably connected to both of the limit shaft plates. A rotating bearing is rotatably connected to the rotating shaft. A fixed pulley is fixedly connected to the rotating bearing. Elastic components are arranged between the limit shaft plates and the installation rod bodies.

[0006] Furthermore, installation holes are arranged inside the limit shaft plates, and the rotating shafts are clamped in the installation holes. The installation holes enable the rotating shafts to be conveniently clamped inside the limit shaft plates, realizing quick installation and disassembly and reducing the complexity of assembly.

[0007] Furthermore, limit plates are arranged on both sides of the upper part of the rotating shaft. The limit plates and the limit shaft plates are connected by first bolts. After the rotating shaft is clamped in the installation hole inside the limit shaft plate, the limit plates on both sides of the rotating shaft are further fixedly connected to the inner wall of the limit shaft plate, further preventing the rotating shaft from shifting or displacing during operation, thereby maintaining the stability of the entire installation structure.

[0008] Further, a through hole is provided on one side of the upper part of the limit shaft plate, a base hole is provided on one side of the upper part of the rotating shaft, and a second bolt passing through the through hole and the base hole is provided on one side of the upper part of the limit shaft plate. By providing the through hole on the limit shaft plate and the base hole on the rotating shaft and using the second bolt for fixation, the connection strength between the two can be effectively increased, ensuring that it is not easily loosened under high-load conditions. The penetrating connection of the second bolt prevents the rotation or displacement of the rotating shaft, ensuring the stability and safety of the rotating shaft during operation.

[0009] Further, the elastic component is a buffer spring. The buffer spring is sleeved on the mounting rod body. One end of the buffer spring abuts against the limit shaft plate, and the end of the buffer spring away from the limit shaft plate abuts against the mounting frame body.

[0010] Further, a number of reinforcing plates are provided between the two mounting frame bodies. The reinforcing plates provide additional support, enhance the connection stability between the mounting frame bodies, and reduce the relative displacement caused by vibration or impact.

[0011] Further, a protective cover is also provided between the two mounting frame bodies. The protective cover can effectively block the entry of dust, moisture and other pollutants, protecting the internal components from the influence of the external environment.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] Rotating shafts can be detachably connected to both limit shaft plates. The detachably connected rotating shafts facilitate the disassembly and replacement of the fixed pulleys. A rotating bearing is rotatably connected to the rotating shaft, and the rotating bearing enables the fixed pulley to rotate flexibly, thereby effectively changing the direction of the force and improving the operation efficiency. A fixed pulley is fixedly connected to the rotating bearing. Elastic components are provided between the limit shaft plate and the mounting rod body. When the fixed pulley is subjected to a large gravity or impact force, the elastic components can compress and absorb part of the impact energy, thereby reducing the direct pressure on the limit shaft plate, preventing the instantaneous impact on the structure caused by sudden load changes, and reducing the risk of equipment damage. The design of the detachably connected rotating shaft makes the replacement and maintenance of the fixed pulley more convenient, the installation process is simple, the equipment downtime is reduced, and the maintenance cost is lowered.

[0024] Please refer to Figure 1-2 As shown, in an embodiment of the present invention, a fixed pulley mounting structure for a cold rolling traveling crane includes two mounting frames 1. Below the two mounting frames 1, there is a mounting rod body 2. Through the combination of the two mounting frames 1 and the mounting rod body 2, the load is evenly distributed, and the overall load-bearing capacity is improved. On both of the two mounting rod bodies 2, there are limit shaft plates 3. A rotating shaft 4 is detachably connected to both of the two limit shaft plates 3. The detachable rotating shaft 4 facilitates the disassembly and replacement of the fixed pulley 6. A rotating bearing 5 is rotatably connected to the rotating shaft 4. The rotating bearing 5 enables the fixed pulley 6 to rotate flexibly, thereby effectively changing the direction of force and improving the operation efficiency. A fixed pulley 6 is fixedly connected to the rotating bearing 5. An elastic component 7 is provided between each limit shaft plate 3 and the mounting rod body 2. When the fixed pulley 6 is subjected to a large gravity or impact force, the elastic component 7 can be compressed to absorb part of the impact energy, thereby reducing the direct pressure on the limit shaft plate 3 and preventing the instantaneous impact on the structure caused by a sudden load change and reducing damage.

[0025] In one embodiment, please refer to Figure 1 and Figure 2 As shown, each limit shaft plate 3 is provided with a mounting hole 31. The rotating shaft 4 is clamped in the mounting hole 31.

The limit plates 41 and the limit shaft plates 3 are connected by first bolts 8. After the rotating shaft 4 is clamped in the mounting hole 31 inside the limit shaft plate 3, the limit plates 41 on both sides of the rotating shaft 4 are further fixedly connected to the inner wall of the limit shaft plate 3, further preventing the rotating shaft 4 from shifting or displacing during operation, thereby maintaining the stability of the entire mounting structure.

By means of the through hole 32 provided on the limit shaft plate 3 and the base hole 411 on the rotating shaft 4 and fixing with the second bolt 9, the connection strength between the two can be effectively increased, ensuring that it is not easy to loosen under high load conditions. The penetrating connection of the second bolt 9 prevents the rotation or displacement of the rotating shaft 4, ensuring the stability and safety of the rotating shaft 4 during operation.

[0028] In one embodiment, please refer to Figure 1 and Figure 2 As shown, the elastic component 7 is a buffer spring 71. The buffer spring 71 is sleeved on the mounting rod body 2. One end of the buffer spring 71 abuts against the limit shaft plate 3, and the end of the buffer spring 71 away from the limit shaft plate 3 abuts against the mounting frame body 1. The buffer spring 71 can effectively absorb and mitigate external impact forces, preventing these forces from being directly transmitted to the limit shaft plate 3 and the rotating shaft 4, thereby reducing the risk of damage caused by sudden loads.

[0029] In one embodiment, please refer to Figure 1 and Figure 2 As shown, a number of reinforcing plates 10 are provided between the two mounting frame bodies 1. The reinforcing plates 10 can effectively disperse the load applied on the mounting frame bodies 1, improve the bending and shear resistance of the overall structure, prevent deformation or damage. The reinforcing plates 10 provide additional support, enhance the connection stability between the mounting frame bodies 1, and reduce the relative displacement caused by vibration or impact.

[0030] In one embodiment, please refer to Figure 1 and Figure 2 As shown, a protective cover 11 is also provided between the two mounting frame bodies 1.
