[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 - Figure 3 , the utility model provides an embodiment: a traction device for disassembling and assembling a tower crane, comprising a disassembling and assembling device 1, an extension platform 2 is fixedly connected to one side of the outer wall of the disassembling and assembling device 1, a traction plate 3 is slidably connected to the top of the extension platform 2, a motor 4 is fixedly connected inside the traction plate 3, a driving sprocket 5 is fixedly connected to the output end of the motor 4, a driven sprocket 6 is rotatably connected inside the traction plate 3, a chain 7 is arranged between the driving sprocket 5 and the driven sprocket 6, a transmission shaft 8 is fixedly connected inside the driven sprocket 6, a gear 9 is fixedly connected to both sides of the outer wall of the transmission shaft 8, a tooth plate 10 is fixedly connected inside the disassembling and assembling device 1, a plurality of limit blocks 23 are fixedly connected to the top of the traction plate 3, the gear 9 is meshed with the tooth plate 10, wheels 11 are rotatably connected to both sides of the outer wall of the traction plate 3, a guide groove 12 is opened inside the extension platform 2, the outer wall of the wheel 11 is slidably connected inside the guide groove 12, and a guide component is arranged inside the traction plate 3, the guide component is used to prevent the fixed component from deviating from the preset route when moving;

[0024] Specifically, when using the traction device for disassembling and assembling a tower crane, it is first necessary to lift the standard section of the tower crane in preparation for disassembly, and then start the motor 4. The operation of the motor 4 drives the driving sprocket 5 to start rotating, and the driving sprocket 5 is connected to the driven sprocket 6 through the chain 7, so that the driven sprocket 6 also starts to rotate. The rotation of the driven sprocket 6 transmits torque through the transmission shaft 8, and then drives the gear 9 to rotate. The gear 9 and the tooth plate 10 are closely matched, so that the traction plate 3 is acted upon by the force and starts to move toward the inside of the disassembling and assembling device 1. The movement of the traction plate 3 will continue until it moves to the bottom position of the standard section. At this time, the operator will stop the operation of the motor 4, and then slowly lower the standard section onto the traction plate 3. After the standard section is safely placed on the traction plate After the plate 3 is put on, the operator can start the disassembly of the standard section. After the disassembly is completed, the operator starts the motor 4 again, but this time the motor 4 is reversed. The reverse rotation of the motor 4 drives the active sprocket 5 and the chain 7, and then the driven sprocket 6 and the transmission shaft 8 are also reversed, and the gear 9 is reversed accordingly. The traction plate 3 starts to move to the outside of the disassembly and assembly device 1 with the cooperation of the tooth plate 10. The movement of the traction plate 3 pulls the standard section out of the tower crane body. Finally, the operator can use the function of the tower crane body to safely put the disassembled tower crane standard section on the ground to complete the entire disassembly process. Through such steps, the traction device for disassembly and assembly of the tower crane ensures the smooth progress of the disassembly operation, while ensuring the safety and efficiency of the operation.

[0025] Reference Figure 1 - Figure 3The guide assembly includes a transmission rod 15 and a sliding column 16, the outer wall of the sliding column 16 is slidably connected to the inside of the transmission rod 15, and both sides of the outer wall of the sliding column 16 are fixedly connected to the inside of the traction plate 3;

[0026] Specifically, in the traction device for disassembling and assembling a tower crane, the transmission rod 15 and the sliding column 16 ensure that the fixing block 13 can accurately reach the specified position along the predetermined route, so as to accurately clamp and process the standard section and avoid operational errors caused by position deviation.

[0027] Reference Figure 1 - Figure 3 , a motor 2 17 is fixedly connected inside the traction plate 3, a gear 2 18 is fixedly connected to the output end of the motor 2 17, a connecting rod 14 is fixedly connected to one side of the outer wall of the transmission rod 15, and the connecting rod 14 is slidably connected to the outer wall of the sliding column 16 inside, a disc 19 is rotatably connected inside the traction plate 3, a gear ring 20 is fixedly connected to the outer wall of the disc 19, and the gear 2 18 is meshed with the gear ring 20, and two fixed blocks 13 are fixedly connected to one side of the outer wall of the connecting rod 14, and both sides of the outer wall of the fixed block 13 are slidably connected to the inside of the traction plate 3, an inclined groove 21 is opened inside the disc 19, and the outer wall of the disc 19 is slidably connected to the inside of the inclined groove 21, a slide groove 22 is opened inside the traction plate 3, and both sides of the outer wall of the fixed block 13 are slidably connected to the inside of the slide groove 22;

[0028] Specifically, before preparing to tow the standard section, the operator can start the motor 2 17 according to the specific needs of the site. The start of the motor 2 17 will drive the gear 2 18 to start rotating, and the gear 2 18 will mesh with the gear ring 20, thereby driving the disc 19 to rotate. During the rotation of the disc 19, the two transmission rods 15 will approach each other. This movement of the transmission rod 15 will be transmitted through the connecting rod 14, thereby pushing the fixed block 13 to move toward the standard section of the tower crane. When the fixed block 13 contacts the standard section, it will tightly clamp the standard section to ensure that it remains stable during the towing process, thereby greatly reducing the risk of loosening, slipping or falling off of the standard section under severe weather conditions. The coordination and precise control of this series of actions ensure the safety and reliability of the disassembly and assembly operations of the tower crane. This design is particularly important, especially under strong winds or other unstable weather conditions. Through this mechanism, the safety and smooth progress of the entire process are ensured.

[0029] Working principle: When using the traction device for disassembling and assembling a tower crane, when the disassembling and assembling device 1 lifts the standard section of the tower crane to prepare for disassembly, start the motor 4, and then the motor 4 drives the active sprocket 5 to rotate, so that the active sprocket 5 drives the driven sprocket 6 to rotate through the chain 7, and then when the driven sprocket 6 rotates, the transmission shaft 8 is forced to drive the gear 9 to rotate. At this time, through the cooperation with the tooth plate 10, the traction plate 3 is forced to move toward the inside of the disassembling and assembling device 1 until it moves to the bottom of the standard section, stop the motor 4, and then lower the standard section onto the traction plate 3, and then disassemble the standard section. After the disassembly is completed, start the motor -4 is reversed, so that the standard section is pulled to move outside the disassembly and assembly device 1. After the pulling movement is completed, the tower crane body can be used to put the standard section on the ground. Before preparing to pull the standard section, the motor 2 17 can be started as needed, and the motor 2 17 drives the gear 2 18 to rotate, and then the gear 2 18 drives the disc 19 to rotate through the gear ring 20. When the disc 19 rotates, the two transmission rods 15 are close to each other, and the movement of the transmission rod 15 will drive the connecting rod 14 to move, so that the fixing block 13 moves toward the standard section until the standard section is clamped and fixed, thereby reducing the risk of loosening, slipping or falling off of the standard section in bad weather.
