Description

Technical Field

[0001] This application relates to the technical field of airport runway maintenance, and particularly to a device for removing glue from airport runway surfaces. Background Art

[0002] Due to frequent aircraft takeoffs and landings, a large amount of rubber residues will accumulate on the airport runway surface. These rubber residues will not only affect the friction coefficient of the runway, reduce the safety performance of aircraft, but also increase the maintenance cost. Therefore, it is necessary to remove the rubber residues.

[0003] Chinese Patent No. CN221837467U discloses a road surface cleaning device for road construction, which includes a housing. An inclined guide frame is fixedly installed inside the housing. A conveyor belt is arranged inside the inclined guide frame. A rubber scraper is fixedly connected to the outer side of the conveyor belt. A shovel plate is fixedly installed at the bottom of the inclined guide frame. The advantages are as follows: After the shovel plate at the bottom of the inclined guide frame shovels the mud on the road surface, it can directly slide to the lower side of the conveyor belt, so that the conveyor belt can push the shoveled mud through the rubber scraper. Under the push of the scraper on the conveyor belt, the mud can be directly pushed into the collection box for collection. The roller rotates and moves the collection box out of the housing through the U-shaped frame. At the same time, the collection box can be flipped between two moving blocks, making the whole operation process of moving the collection box out of the housing and pouring the mud inside the collection box relatively labor-saving.

[0004] In view of the above related technologies, in the prior art, a shovel plate is used to scrape the dirt on the road surface, and then the cooperation of a conveyor belt and a rubber scraper is used to discharge the dirt into the collection box to achieve the effect of road surface cleaning. However, if this device is applied to cleaning the rubber residues on the ground, the rubber residues are caused by the intense friction of the aircraft tires on the road surface, and after the tires are worn, they adhere to the road surface with a relatively high adhesion force. Maintenance personnel need to control the housing to move repeatedly many times, so that the shovel plate repeatedly scrapes the rubber residues, which makes the cleaning difficult and reduces the cleaning efficiency of the road surface cleaning device. Summary of the Invention

[0005] In order to improve the cleaning efficiency of the device for removing glue from airport runway surfaces, this application provides a device for removing glue from airport runway surfaces.

A connecting shaft is connected between two of the moving wheels at one end of the mobile vehicle. A number of the connecting gears are connected to the connecting shaft. The rotating shaft is rotatably connected to the mobile vehicle. A limiting bar is connected to the rotating shaft. The sliding sleeve is sleeved on the rotating shaft and is in sliding fit with the limiting bar. A number of the rotating gears are connected to the sliding sleeve. The rotating gears and the connecting gears are in one-to-one correspondence. The feeding motor is installed on the mobile vehicle and is coaxially connected to the rotating shaft.

The water outlet hose is connected to the lifting frame and is connected to the rotating end of the cleaning disc through a bearing. Both the rotating motor and the micro pump are electrically connected to the battery box.

[0015] By adopting the above technical solution, when cleaning the rubber residue, the lifting member is used to drive the lifting frame to descend until the steel brush touches the ground. Then the rotating motor is started to make the cleaning disc rotate. At the same time, the micro pump is started to make the cleaning agent enter the cleaning disc and flow out through the liquid outlet holes, so that while the steel brush cleans the rubber residue, the cleaning agent is used to make the rubber residue quickly degum, achieving the effect of cleaning the rubber residue.
