Description

Technical Field

[0001] The invention relates to the field of robot cleaning, in particular to an airport runway pavement cleaning robot. Background Art

[0002] An airport runway refers to an extra-long strip of land in an airport for aircraft to take off or land. It is made of materials such as asphalt or concrete, and needs to be inspected and maintained in real time to reduce hidden dangers during aircraft takeoff and landing. If there are stones, metal objects, plastic and other objects on the runway surface, these foreign objects will damage the aircraft tires and be sucked into the engine, causing engine failure, which poses a very high safety hazard. The existing method of cleaning the runway surface is mostly to clean and maintain it by manually carrying cleaning equipment and manual inspection, but this method is inefficient and cannot be quickly cleaned for foreign objects that are difficult to clean, such as sticky rubber fragments and plastic.

[0003] In view of this, the airport runway pavement cleaning robot is proposed. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides an airport runway pavement cleaning robot, which drives the cleaning wheel to rotate through a driving component to facilitate the cleaning of foreign objects on the runway pavement. The scraper and the brush rod can be used to switch between two different applicable situations to clean foreign objects.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: an airport runway pavement cleaning robot comprises a body, a walking mechanism and a cleaning component;

[0006] The walking mechanism is arranged at the bottom of the front and rear ends of the machine body, the cleaning assembly is arranged at the bottom of the machine body, and includes an electric telescopic rod arranged inside the machine body, a slider arranged at the bottom end of the electric telescopic rod, and a cleaning wheel arranged between the two sliders. A collection box is provided at the position of the slider close to the cleaning wheel, and a driving assembly is provided on the right side of the slider, and is used to drive the cleaning wheel to rotate.

[0007] The present invention has the following beneficial effects:

[0008] 1. The airport runway pavement cleaning robot can drive the cleaning wheel at the bottom to contact the ground through the electric telescopic rod arranged in the body, and use the driving component to drive the cleaning wheel to rotate, so that foreign matter on the runway is stored in the inside of the collection box, and it is convenient to shrink inside the body when not in use, reducing damage to the cleaning wheel;

[0009] 2. When the airport runway cleaning robot is cleaning the runway surface, it will encounter difficult-to-clean and easy-to-clean areas. The scraper and brush bar set on the surface of the cleaning wheel can be conveniently switched according to the two different applicable situations;

[0010] 3. The airport runway pavement cleaning robot drives the auxiliary rod and the bidirectional lead screw to rotate synchronously through the rotation of the cleaning wheel. The measuring rod and scale value are used to conveniently measure and check the cracks on the ground for easy maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

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

[0023] See also Figures 1 to 10 The present invention provides an airport runway pavement cleaning robot; it includes a body 1, a walking mechanism and a cleaning component; the walking mechanism is arranged at the bottom of the front and rear ends of the body 1, the cleaning component is arranged at the bottom of the body 1, and includes an electric telescopic rod 2 arranged inside the body 1, a slider 3 arranged at the bottom of the electric telescopic rod 2, and a cleaning wheel 4 arranged between the two sliders 3, a collecting box 5 is arranged at the position of the slider 3 close to the cleaning wheel 4, and a driving component is arranged on the right side of the slider 3, and is used to drive the cleaning wheel 4 to rotate.

[0024] A rotating shaft 6 is inserted into the slider 3, and a cleaning wheel 4 is sleeved on the surface of the rotating shaft 6. The cleaning wheel 4 includes a cross cylinder 7 inside and sleeved on the surface of the rotating shaft 6, a scraper 8 and a brush rod 9 arranged on the surface of the cleaning wheel 4.

[0025] like Figure 6 and Figure 7 As shown, a cavity is provided inside the body 1 for use with the slider 3. When the electric telescopic rod 2 moves up and down, the slider 3 can move up and down inside the cavity to increase stability. The electric telescopic rod 2 is symmetrically arranged with the vertical midline of the body 1 as the symmetry axis.

[0026] like Figure 1As shown, a detachable bottom plate is inserted into one side of the collection box 5 to facilitate cleaning of foreign matter inside the collection box 5 .

[0027] The two ends of the cleaning wheel 4 are fixedly connected to the positioning plate 10 through the positioning column, the surface of the positioning column is fixedly connected to the tension spring 11, and the other end of the tension spring 11 is fixedly connected to the scraper 8 and the brush rod 9 that penetrates into the cleaning wheel 4 and is close to the end of the positioning plate 10.

[0028] The difference between the present invention and the prior art is that;

[0029] In the prior art, when cleaning the runway pavement of an aircraft, most of the time, manually-carried cleaning devices and manual inspection equipment are used to clean and maintain the runway pavement, so as to reduce hidden dangers during takeoff and landing of the aircraft. The present invention provides a walking mechanism at the bottom of the body 1 to facilitate the movement of the equipment. When the pavement needs to be cleaned, the cleaning wheel 4 at the bottom is extended by the electric telescopic rod 2 to collect foreign matter on the ground into the collection box 5. When encountering foreign matter that is difficult to clean, such as sticky rubber and plastic, the scraper 8 on the surface of the cleaning wheel 4 is used to clean it while rotating. When encountering easy-to-clean foreign matter, such as plastic, paper scraps, etc., the brush rod 9 on the surface of the cleaning wheel 4 is used to clean it, so that it is convenient to switch according to the applicable situation.

[0030] The right end of the cross cylinder 7 passes through the inner wall of the cleaning wheel 4 and is provided with a main gear 12, which is sleeved on the surface of the rotating shaft 6. The cleaning wheel 4 is meshed with a sub-gear 13 near the main gear 12. The cleaning wheel 4 is fixedly connected to the main gear 12. The side of the protective shell 14 is fixedly connected to a driving block 15. The output end of the driving block 15 passes through the protective shell 14 and is fixedly connected to the sub-gear 13. The surface of the protective shell 14 is fixedly connected with a positioning bolt.

[0031] like Figure 6 As shown, the left end of the rotating shaft 6 is sleeved with a positioning plate and is fixed to the cleaning wheel 4 by bolts to increase its stability during rotation.

[0032] like Figure 4 As shown, there are four scrapers 8 and four brush rods 9, which are evenly and equidistantly arranged on the surface of the cleaning wheel 4. The protective shell 14 is fixed to the side of the right end of the cleaning wheel 4 by bolts to protect the gears. At the same time, the protective shell 14 can be fixedly connected to the rotating shaft 6 by the positioning bolts on the surface of the protective shell 14. When the rotating rod 6 rotates, the cleaning wheel 4 is synchronously driven to rotate through the protective shell 14.

[0033] like Figure 4 and Figure 8As shown, when the scraper 8 and the brush rod 9 are switched, the driving block 15 (which can be an electric motor) is started. When rotating forward, the scraper 8 is retracted to the inside of the cleaning wheel 4, and the brush rod 9 extends out of the groove on the surface of the cleaning wheel 4. When rotating reversely, it moves in the opposite direction to the forward rotation. The cross cylinder 7 inside it can support it to maintain stability during rotation. The tension spring 11 can reduce the scraper 8 and the brush rod 9 retracted inside it from extending out of the cleaning wheel 4 when the cleaning wheel 4 rotates.

[0034] The elastic coefficient of the tension spring 11 is tight, and the speed of the cleaning wheel 4 is not enough to throw out the scraper 8 and the brush rod 9;

[0035] like Figure 8 As shown, the positioning plate 10 is symmetrically arranged with the vertical center line of the cleaning wheel 4 as the symmetry axis, and the tension springs 11 are arranged at both ends of the cross cylinder 7. The side of the positioning plate 10 away from the cross cylinder 7 is fixedly connected with a conical fixing block, and the side of the cross cylinder 7 close to the positioning plate 7 is fixedly connected with an auxiliary block. The purpose of this arrangement is that when the cross cylinder 7 rotates left and right, the auxiliary block can be limited by the conical fixing block, while reducing the rotation of the cross cylinder 7 inside it when the cleaning wheel 4 rotates.

[0036] The driving assembly includes a driving motor 16 fixedly connected to the right side of the slider 3, a gear rod 17 fixedly connected to the output end of the driving motor 16, and one end of the gear rod 17 away from the driving motor 16 is fixedly connected to the rotating shaft 6, and the other end of the rotating shaft 6 is arranged inside the left end slider.

[0037] The collecting box 5 is fixedly connected to the side of the slider 3 along the first direction through a support rod. The inner part of the slider 3 near the gear rod 17 is meshed with an auxiliary rod 18, and the end of the auxiliary rod 18 away from the gear rod 17 is meshed with a bidirectional screw rod 19.

[0038] A measuring rod 20 is threadedly connected to the surface of the bidirectional screw rod 19, a scale value 21 is provided on the back of the collecting box 5 near the measuring rod 20, a base 22 is fixedly connected to the upper surface of the body 1, a rotatable support tube 23 is inserted into the upper surface of the base 22, a first camera 24 is provided on the top of the support tube 23, a second camera 25 is provided on the lower surface of the body 1 near the measuring rod 20, and a sliding mechanism for driving the support tube 23 to rotate is provided inside the base 22.

[0039] like Figure 7As shown, when the driving motor 16 rotates forward, the bevel gear on the surface of the gear rod 17 meshes with one side of the auxiliary rod 18, synchronously driving the bidirectional lead screw 19 to rotate. At this time, the measuring rod 20 moves toward the middle on its surface, and the distance is measured by the scale value 21 set on the surface of the collecting box 5. The measured distance can be checked by the second camera 25 set on the lower surface of the body 1, which is convenient for later maintenance. The inner wall of the measuring rod 20 is provided with a thread compatible with the bidirectional lead screw 19, which is convenient for adjusting the measuring rod 20 to move.

[0040] An exhaust pipe 29 is fixedly connected to the upper surface of the base 22 near the support tube 23 and is used in conjunction with the sliding mechanism. A separation mechanism is provided at the auxiliary rod 18 near the gear rod 17 and is connected to the air outlet end of the exhaust pipe 29. A solenoid valve 28 is provided at one end of the exhaust pipe 29 away from the support tube 23. A telescopic hose 37 is fixedly connected to the upper surface of the collection box 5, one end of which is connected to the air outlet end of the exhaust pipe 29, and the other end is connected to the separation mechanism.

[0041] like Figure 1 As shown, an exhaust pipe 29 is provided on the upper surface of the body 1, and a branch pipe is provided on the surface of one end away from the support tube 23, and the gas outlet end of the branch pipe is fixedly connected to the upper surface of the body 1, and the exhausted gas is close to the measuring rod 20 and the scale value 21, so that the dust on the surface can be cleaned conveniently;

[0042] The telescopic hose 37 provided on the upper surface of the collecting box 5 can be used in conjunction with the electric telescopic rod 2, so that when the electric telescopic rod 2 is extended and retracted up and down, the telescopic hose 37 can perform telescopic movement synchronously. There are two solenoid valves 28, one of which is provided at the branch position, so as to conveniently control the position where the gas is discharged.

[0043] The sliding mechanism includes a reciprocating screw 31 arranged inside the base 22, a sliding ring 32 arranged on the surface of the reciprocating screw 31, and a pressure component arranged on the top of the sliding ring 32; the pressure component includes a piston rod 33 arranged on the top of the slider 32, and a sleeve 34 arranged at the end of the piston rod 33 away from the sliding ring 32. The right end of the reciprocating screw 31 is fixedly connected to a limiting ring 43, and a belt 44 is provided on the surface of the limiting ring 43. The bottom end of the belt 44 passes through the body 1 and is arranged on the surface of the walking mechanism.

[0044] One end of the sleeve 34 away from the piston rod 33 is fixedly connected to the side wall of the support tube 23, and the upper surface of the sleeve 34 close to the support tube 23 is fixedly connected to a telescopic hose 25 and communicated with the air inlet end of the exhaust pipe 29. A first one-way valve 36 is provided inside the sleeve 34 close to the support tube 23.

[0045] The separation mechanism includes an extrusion ring 38 arranged at one end of the bidirectional screw 19 close to the auxiliary rod 18, a compression spring 39 arranged on one side close to the extrusion ring 38, and a second one-way valve 40 and a solenoid valve 41 arranged inside the collection box 5 close to the extrusion ring 38.

[0046] like Figure 2 As shown, a slideway (not shown in the figure) is provided on the surface of the reciprocating screw rod 31, and a pin (not shown in the figure) adapted to the slideway is provided on the inner wall of the sliding ring 32. When the reciprocating screw rod 31 rotates, the pin drives the sliding ring 32 to move back and forth along the slideway.

[0047] When the sliding ring 32 moves left and right, the piston rod 33 and the sleeve 34 are synchronously driven to move left and right, and at the same time, the end of the piston rod 33 away from the sliding ring 32 performs telescopic movement with the sleeve 34;

[0048] When the piston rod 33 extends out of the sleeve 34, the first one-way valve 36 draws air into the sleeve 34. When the piston rod 33 retracts into the sleeve 34, the air inside is squeezed, and the air flows through the telescopic hose 2 35, the exhaust pipe 29 and the telescopic hose 1 37, and enters the extrusion ring 38 and the point a space. At this time, the extrusion ring 38 compresses the compression spring 39 (to the left), and synchronously drives the two-way screw rod 19 to move. At this time, the air flow inside the point b space is discharged from point c, and one end of the two-way screw rod 19 is separated from the auxiliary rod 18 and is not in a meshing state. When the solenoid valve 2 41 is turned on, the compression spring 39 moves quickly to the right with the extrusion ring 38. At this time, the air flow in the a space is discharged from point d, and the two-way screw rod 19 is meshed and connected with the auxiliary rod 18 again.

[0049] Before this, the electromagnetic valve 28 inside the exhaust pipe 29 is in a conducting state, and the electromagnetic valve 28 in the branch position is in a non-conducting state;

[0050] When the solenoid valve 28 inside the branch pipe is turned on, the solenoid valve 28 at the exhaust pipe 29 is in a non-conducting state, and the collecting box 5 is in a raised state, the generated airflow can remove dust from the measuring rod 20 and the scale value 21;

[0051] The purpose of setting the separation mechanism is that when the measuring rod 20 is not needed to be adjusted, it can be separated. At this time, the measuring rod 20 and the scale value are dusted. When measurement is required, the bidirectional screw 19 is engaged and connected with the auxiliary rod 18.

[0052] The walking mechanism includes a support plate 26 fixedly connected to the bottom of the body 1, a connecting shaft 27 arranged between the two support plates 26, and walking wheels 30 arranged at both ends of the two connecting shafts 27. The pressurizing mechanism is used in conjunction with the connecting shaft 27. A water tank 42 is fixedly connected to the upper surface of the body 1, and a cleaning component is provided inside.

[0053] like Figure 2 and Figure 3 As shown, when the walking wheel 30 rotates, it synchronously drives the connecting shaft 27 to rotate, and synchronously drives the reciprocating screw 31 to rotate. At this time, the sliding ring 32 drives the pressurizing component to operate synchronously, and while generating pressure, it drives the support tube 23 to reciprocate left and right, and synchronously drives the first camera 24 on its top to reciprocate left and right, thereby increasing the detection range of the road.

[0054] like Fig.10 As shown, a water pump and a water source are provided inside the water storage tank 42, and a bend pipe is fixedly connected to the water inlet end of the water pump, one end of the bend pipe penetrates into the water storage tank 42, and the water outlet end of the water pump is connected to the body 1 (as shown in FIG. Figure 1 As shown), the inner top wall of the body 1 is provided with a nozzle (not shown in the figure) and is connected to the water outlet of the water pump. The nozzle is located above the cleaning wheel 4. When the cleaning wheel 4 needs to be cleaned, the water pump is started to draw water from the water tank 42 and spray it out from the nozzle to facilitate the cleaning of the cleaning wheel 4.

[0055] The electric telescopic rod 2, drive motor 16, solenoid valve 1 28, solenoid valve 2 41, first camera 24, second camera 25 and water pump described in the above text are all existing technologies and are only cited here. The specific structure will not be described in detail.

[0056] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer or the like.

[0057] In the present invention, the working steps of the device are as follows:

[0058] 1. When in use, the machine body 1 moves on the runway surface through the walking mechanism at the bottom, and detects the runway surface through the first camera 24 and the second camera 25. When encountering foreign objects, it stops, and the electric telescopic rod 2 is started to drive the cleaning wheel 4 at the bottom to move downward, and stops when the scraper 8 or the brush rod 9 touches the ground;

[0059] 2. Start the driving motor 16, and synchronously drive the gear rod 17 and the rotating shaft 6 to rotate. When foreign objects that are difficult to clean on the road surface are detected, the cleaning wheel 4 is rotated, and the foreign objects are scraped off the ground by the scraper 8, and then the brush rod 9 is switched to collect the foreign objects into the collection box 5;

[0060] 3. When the cleaning rod 4 rotates, the gear rod 17, the auxiliary rod 18 and the bidirectional screw rod 19 are synchronously driven to rotate, so as to facilitate the adjustment of the distance between the measuring rods 20. The distance between the measuring rods 20 can be checked through the scale value 21, so as to quickly measure the cracks in the runway pavement for easy maintenance.

[0061] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
