Since the driving gear 506 is meshed with the driven gear 516, the stepper motor 507 drives the two shaft rods 518 to rotate synchronously, and then the shaft rod 518 drives the driving wheel 517 and the anti-slip sleeve 512 to rotate, so that the movable frame 504 moves on the hoisting cable 9 until it moves to a suitable position. At this time, the structural component contacts the rubber touch plate 503 and presses it down, thereby moving the fixing seat 513, and the fixing seat 513 drives the connecting rod 514 to operate, so that the mounting seat 515 moves inside the mounting groove 510, and the deceleration spring rod 511 is stretched to reduce the force. After that, the hoisting cable 9 lifts the structural component, and multiple rubber touch plates 503 are in contact with the structural component. At the same time, the elastic plate 509 is deformed until the hoisting is completed and the elastic plate 509 recovers. In a specific application scenario, the hoisting and wear-resistant module 5 is suitable for the hoisting link of the structural components by the bridge-building machine, that is, the hoisting and wear-resistant module 5 can avoid direct contact between the hoisting cable 9 and the structural components during use, and thus avoid wear between the structural components and the hoisting cable 9 during use, thereby increasing the use effect and safety of the device during use, and can increase the service life of the hoisting cable 9, and can also play a certain protective role for the structural components during use, avoiding damage to the structural components caused by the hoisting cable 9, and when in use, the hoisting and wear-resistant module 5 can adjust the position according to the contact point between the structural components and the hoisting cable 9 to increase the applicability of the device and further increase the use effect of the device.

[0028] Specifically, when in use, as the hoisting vehicle 2 is running, the cleaning pump 702 is started, and the cleaning pump 702 discharges the air inside the dust filter bin 703, making the inside of the dust filter bin 703 in a negative pressure state. At this time, the cleaning pipe 705 can clean the dust or fine debris on the guide rail seat 1 through the cleaning port 704, and transport it to the inside of the connecting bin 714 through the connecting pipe 706, and further transport it to the inside of the dust filter bin 703 through the conveying pipe 701. At this time, it can be filtered through the filter bin.

[0030] Specifically, during the hoisting process, the electric telescopic rod 802 and the negative pressure pump 806 are started, and the negative pressure pump 806 discharges the air inside the negative pressure bin 804 through the connecting pipe 805. At the same time, the electric telescopic rod 802 drives the negative pressure bin 804 and the stabilizing suction cup 803 to move, so that the stabilizing suction cup 803 contacts the structural component. At this time, the negative pressure can make the stabilizing suction cup 803 adsorb and fix to the structural component, so as to increase the stability of the hoisting operation. In a specific application scenario, the stabilization module 8 is suitable for the lifting of structural components, that is, when the stabilization module 8 is in use, it can adsorb and fix the structural components through the stabilization suction cup 803, and through the fixed position relationship between the electric telescopic rod 802 and the lifting vehicle 2, the lateral shaking of the structural components can be reduced during lifting, thereby further increasing the safety of the device during use, and reducing the shaking degree can facilitate the installation of the structural components. At the same time, during stable adsorption, the position of the stabilization suction cup 803 can be adjusted according to structural components of different sizes through the electric telescopic rod 802, further increasing the use effect of the device.

[0031] Working principle: When using the hoisting, start the stepper motor 507, and the stepper motor 507 drives the driving gear 506 to rotate. Since the driving gear 506 is meshed with the driven gear 516, the stepper motor 507 drives the two shaft rods 518 to rotate synchronously, and then drives the driving wheel 517 and the anti-slip sleeve 512 to rotate through the shaft rod 518, so that the movable frame 504 moves on the hoisting cable 9 until it moves to a suitable position. At this time, the structural component contacts the rubber touch plate 503 and presses it down, thereby moving the fixing seat 513, and the fixing seat 513 drives the connecting rod 514 to operate, so that the mounting seat 515 moves inside the mounting groove 510, and the slow spring rod 511 is stretched to reduce the force. After that, the hoisting cable 9 lifts the structural component, and multiple rubber touch plates 503 are in contact with the structural component. At the same time, the elastic plate 509 is deformed until the hoisting is completed and the elastic plate 509 recovers. During the hoisting process, the electric telescopic rod 802 and the negative pressure pump 806 are started, and the negative pressure pump 806 discharges the air inside the negative pressure chamber 804 through the connecting pipe 805. At the same time, the electric telescopic rod 802 drives the negative pressure chamber 804 and the stabilizing suction cup 803 to move, so that the stabilizing suction cup 803 contacts the structural component. At this time, the negative pressure can make the stabilizing suction cup 803 adsorb and fix to the structural component, so as to increase the stability of the hoisting operation; During use, as the lifting vehicle 2 runs, the cleaning pump 702 is started, and the cleaning pump 702 discharges the air inside the dust filter bin 703, making its interior in a negative pressure state. At this time, the cleaning pipe 705 can clean the dust or fine debris on the guide rail seat 1 through the cleaning port 704, and transport it to the inside of the connecting bin 714 through the connecting pipe 706, and further transport it to the inside of the dust filter bin 703 through the conveying pipe 701. At this time, it can be filtered through the filter bin. At the same time, the gas will contact the windward plate 710 when passing through the impact frame 709, so that the telescopic spring 707 is compressed. After that, with the elasticity of the telescopic spring 707, the impact frame 709 elastically reciprocates inside the dust filter bin 703, thereby driving the impact rod 711 to impact the filter frame 712 to avoid blockage until the cleaning is completed.
