Description

Technical Field

[0001] This utility model relates to the technical field of airport runway construction equipment, specifically a marking mechanism for airport signage construction. Background Technology

[0002] An airport, also known as an airfield, airport or aviation station, is a site specifically for the take-off and landing of aircraft. It typically includes facilities such as runways, control towers, aprons, and terminals, and provides functions such as air traffic control and passenger services.

[0003] Road markings include hot-melt marking, room-temperature cold-paint marking, colored anti-skid marking, vibrating anti-skid reflective marking, and pre-formed marking. Hot-melt marking is currently one of the most widely used types of road markings in my country. The quality control of hot-melt marking construction is affected by various factors, such as material quality, natural environment, and usage scenario.

[0004] For example, utility model patent CN212670227U discloses a road marking removal device for airport construction, including a base, a push rod on the left side of the base, a lifting box on the right side of the push rod, first sliding grooves on both sides of the inner wall of the lifting box, a threaded rod running vertically through the lifting box, a position display on the top of the threaded rod, an adjustment plate above the position display, a moving plate on the threaded rod, a connecting rod below the moving plate, a load plate at the bottom of the connecting rod, second sliding grooves on both sides of the load plate, a reduction motor on the load plate, shock-absorbing springs on both sides of the load plate, a chassis below the reduction motor, and a wire brush head on the chassis. The airport road marking removal device disclosed in this utility model uses a linear motor to drive an ultrasonic thickness detection probe to detect the thickness of the road marking coating. Different grinding depths are adjusted according to the detected thickness, which can easily remove various road markings in the airport. However, there is a problem that it is inconvenient when the wire brush head that has been used for a long time needs to be repaired or replaced. It will cause the entire device to be lifted by external equipment to repair the wire brush head, which will reduce the repair efficiency of the wire brush head and thus reduce the grinding and removal efficiency of the road marking. To address this, we propose a road marking mechanism for airport sign and sign construction. Utility Model Content

[0027] In this embodiment, the base lifting mechanism 6 includes a mounting plate 61. A U-shaped plate 5 is fixedly mounted on the inner end of the mounting plate 61. A first electric push rod 62 is fixedly mounted on the middle of the lower end of the mounting plate 61. A short gear 63 is rotatably connected to the output end of the first electric push rod 62 through a bearing. A first long gear 64 is meshed with the outer end of the short gear 63.

The first long gear 64 drives the follower shaft 65 to rotate. The first long gear 64 drives the two centrally symmetrical racks 66 to move away from each other. Each rack 66 drives the slide bar 67 to slide in the slide groove 4. At this time, the rack 66 drives the first wedge block 68 to move outward. The first wedge block 68 drives the second wedge block 69 to move downward. At this time, the second wedge block 69 drives the guide post 610, the moving plate 611, and the locking universal wheel body 612 to move downward.

[0029] In this embodiment, the grinding component 7 includes a stepper motor 71, a U-shaped plate 5 is fixedly installed at the lower end of the stepper motor 71, a rotating shaft 72 is fixedly installed at the output end of the stepper motor 71, a second long gear 73 is fixedly installed at the lower end of the rotating shaft 72, a second electric push rod 74 is fixedly installed at the lower end of the second long gear 73, a movable seat 75 is fixedly installed at the output end of the second electric push rod 74, and a wire brush 76 is provided at the lower end of the movable seat 75.

[0032] Specifically, the detection component 8 can perform thickness detection on markings of different thicknesses using the ultrasonic thickness detection probe 82, thereby reducing the wear of the wire brush 76.

[0033] In this embodiment, a follower shaft 65 is fixedly installed at the lower end of the first long gear 64, and the lower end of the follower shaft 65 is rotatably connected to the movable base 1 through a bearing.

[0034] Specifically, the stability of the first long gear 64 during rotation can be improved by using the follower shaft 65.

[0035] In this embodiment, a slide bar 67 is fixedly installed at the lower end of each rack 66, and a slide groove 4 is slidably connected to the outer end of each slide bar 67.

[0037] In this embodiment, the guide post 610 passes through the movable base 1, and the outer end of the guide post 610 is slidably connected to the movable base 1.

[0038] Specifically, ensure that the guide post 610 does not interfere with the movable base 1 during the sliding process.

[0039] In this embodiment, two symmetrically arranged push-pull handles 2 are fixedly installed on the upper left side of the mobile base 1.

[0040] Specifically, the device can be operated by pushing or pulling handle 2.

[0041] In this embodiment, the upper end of the spring 613 is fixedly installed with the movable base 1, and the spring 613 is sleeved with the guide post 610.

[0042] Specifically, it ensures that the spring 613 does not interfere with the guide post 610 during the compression and rebound process.

[0043] Working Principle: During use, the stepper motor 71 and the second electric push rod 74 are activated. The output of the stepper motor 71 drives the rotating shaft 72 and the second long gear 73 to rotate. The second long gear 73 drives the second electric push rod 74 to rotate, which in turn drives the moving base 75 and the wire brush 76 to rotate. Simultaneously, the output of the second electric push rod 74 drives the moving base 75 and the wire brush 76 to grind and remove the ground markings. During grinding, the short gear 63 is not engaged with the first long gear 64. When the wire brush 76 needs to be inspected or replaced, the first electric push rod 62 and the stepper motor 71 are activated. The output of the first electric push rod 62 drives the short gear 63 to move downwards, where it engages with the first long gear 64 and the second long gear 73. At this time, the output of the stepper motor 71 drives the rotating shaft 72 to rotate. The rotating shaft 72 drives the second long gear 73 to rotate, which in turn drives the short gear 63 to rotate. At this time, the short gear 63 drives the first long gear 64 to rotate. The first long gear 64 drives the follower shaft 65 to rotate. The first long gear 64 drives the two centrally symmetrical racks 66 to move away from each other. Each rack 66 drives the slide bar 67 to slide in the slide groove 4. At this time, the rack 66 drives the first wedge block 68 to move outward. The first wedge block 68 drives the second wedge block 69 to move downward. At this time, the second wedge block 69 drives the guide post 610, the moving plate 611, and the locking universal wheel body 612 to move downward. At this time, the spring 613 is stretched. During this process, the moving base 1 is lifted up, and the space between the moving base 1 and the ground increases, making it easier for the staff to inspect and replace the wire brush 76.
