In view of the above problems, the present application provides a transportation device 1000.

[0045] Referring to Figures 1-12In the embodiment of the present application, the transport device 1000 comprises a transport body 300, a support assembly 200, and a fixing assembly 100, wherein the transport body 300 has a first direction and a second direction; the support assembly 200 comprises a support unit 21 and a moving unit 23, the moving unit 23 is connected to the transport body 300 and the support unit 21, and is used to drive the support unit 21 to move along the first direction and the second direction relative to the transport body 300; the fixing assembly 100 is connected to the support unit 21 and / or the transport body 300, at least part of the structure of the fixing assembly 100 moves relative to the support unit 21 and / or the transport body 300, and is used to support and fix the support unit 21 and / or the transport body 300.

[0046] It should be noted that the building stairs 4000 mostly comprise a kick surface 43 and a tread surface 45, the kick surface 43 is a plane perpendicular to the horizontal plane, and the tread surface 45 is a plane parallel to the horizontal plane. For the convenience of the following description, the first direction and the second direction are introduced, corresponding to the process of the transport device 1000 on the stairs 4000, the first direction refers to the direction of vertically upward perpendicular to the horizontal plane, and the second direction refers to the direction perpendicular to the kick surface 43 of the stairs 4000; corresponding to the process of the transport device 1000 on the stairs 4000, the first direction refers to the direction of vertically upward perpendicular to the horizontal plane, and the second direction refers to the direction perpendicular to the kick surface 43 of the stairs 4000. Figure 1 The transport device 1000 shown in the figure, the first direction is the up-down direction, and the second direction is the front-back direction.

[0047] Therefore, it can be understood that, taking the process of the transportation device 1000 climbing the stairs 4000 as an example, the process of the transportation device 1000 moving on the stairs 4000 can be divided into an alternating lifting process and a moving process, wherein the lifting process is: first driving the support unit 21 to descend in the first direction by the moving unit 23, at this time, since the support unit 21 abuts on the tread 45 of the stairs 4000, the moving unit 23 can be driven by the force of the support unit 21 in the opposite direction to drive the transportation main body 300 to lift, and the transportation main body 300 can be lifted to the plane of the tread 45 of the next level of stairs 4000, and then driving the support unit 21 to move forward in the second direction by the moving unit 23, when the support unit 21 abuts on the kick surface 43 of the stairs 4000, the moving unit 23 can be driven by the force of the support unit 21 in the second direction to move the transportation main body 300 to the tread 45 of the next level of stairs 4000, so that the transportation main body 300 can move from the next level of stairs 4000 to the next level of stairs 4000, and realize the climbing of the transportation main body 300 on the stairs 4000.

After one lifting process and one moving process, the transportation main body 300 and the support unit 21 can be alternately moved from the next level of stairs 4000 to the next level of stairs 4000, realizing the step-by-step climbing of the transportation device 1000 on the stairs 4000, and then the transportation device 1000 can repeatedly run the lifting process and the moving process, so that the transportation device 1000 can move on the stairs 4000 to multiple floors, so as to achieve the purpose of transporting the cleaning device to each floor for cleaning, and ensure the normal operation of the cleaning equipment.

[0048] When the conveying device 1000 moves on the stairs 4000, the conveying body 300 is lifted to the plane of the tread 45 of the next level of the stairs 4000 and then moves to the tread 45 of the next level of the stairs 4000, or the support unit 21 is lifted to the plane of the tread 45 of the next level of the stairs 4000 and then moves to the tread 45 of the next level of the stairs 4000, only part of the structure of the conveying device 1000 is in contact with the stairs 4000, so that the center of gravity of the conveying device 1000 is not stable, and when an external force is applied, the conveying device 1000 is prone to overturning. In the embodiment of the present application, the fixing assembly 100 is arranged on the support unit 21 and / or the conveying body 300, which can be connected to the plane where the support unit 21 and / or the conveying body 300 is located during the movement of the conveying device 1000, and the fixing assembly 100 can be used to fix the support unit 21 and / or the conveying body 300, thereby effectively improving the stability and reliability of the movement of the conveying device 1000.

At this time, the suction device 50 can be used to suck air through the exhaust passage 311b of the suction accessory 31b and introduce the air into the cylinder-piston assembly, so that the high-pressure air flow in the cylinder pushes the piston to drive the suction accessory 31b to move downward, and the driving mechanism 10 maintains the pushing force on the connecting piece 31 under the action of the suction device 50, so that the suction accessory 31b can be better adsorbed and fixed on the tread 45 of the staircase 4000. Further, a valve can be connected between the pipeline of the suction device 50 connected to the cylinder-piston assembly and the exhaust pipe 315b. When it is necessary to release the connection between the connecting piece 31 and the tread 45 of the staircase 4000, the valve can be opened to make the air flow in the cylinder-piston assembly flow to the exhaust passage 311b of the suction accessory 31b, and the exhaust hole 313b pushes the connecting piece 31 away from the tread 45 of the staircase 4000. At this time, the decrease of the air pressure in the cylinder-piston assembly can make the piston lift in the first direction, so that the driving mechanism 10 drives the fixed structure 30 to lift away from the tread 45 of the staircase 4000 to avoid the movement of the transportation device 1000, and ensures the normal operation of the transportation device 1000.

[0062] With reference to Figure 5 and Figure 6 In an embodiment of the present application, the connecting piece 31 is provided with a plug-in slot 317b, and the exhaust hole 313b is arranged through the slot bottom wall of the plug-in slot 317b. One end of the fixed structure 30 is movably inserted into the plug-in slot 317b, and opens or closes the exhaust hole 313b during the movement. The outer circumferential side of the end of the fixed structure 30 is spaced from the inner side wall of the plug-in slot 317b to form an exhaust passage.

[0063] In the embodiment, the fixing structure 30 can be connected to the connecting piece 31 by inserting one end into the insertion slot 317b of the connecting piece 31, so that the outer periphery of the end of the fixing structure 30 is arranged between the inner side walls of the insertion slot 317b to form an exhaust passage of the connecting piece 31. When the driving mechanism 10 drives the fixing structure to move up and down in the first direction, the air or bubbles between the suction accessory 31b and the tread 45 of the stairs 4000 can be brought into the exhaust passage 311b by moving the end of the fixing structure 30 in the insertion slot 317b after the suction accessory 31b contacts the tread 45 of the stairs 4000. At this time, a gap can be provided between the slot of the insertion slot 317b and the outer periphery of the fixing structure 30, or an air outlet can be provided in the inner side wall of the insertion slot 317b to pass through the suction accessory 31b, so that the gas in the exhaust passage 311b can be discharged from the insertion slot 317b, effectively reducing the air between the connecting piece 31 and the tread 45 of the stairs 4000, and facilitating better negative pressure adsorption effect of the suction accessory 31b. With the downward movement of the fixing structure 30, the end face of the fixing structure 30 arranged in the insertion slot 317b can be closed to the slot bottom wall of the insertion slot 317b to close the exhaust hole 313b, so that the suction accessory 31b can better maintain the airtight adsorption force between the tread 45 of the stairs 4000, and better connection stability and reliability between the connecting piece 31 and the tread 45 of the stairs 4000.

[0064] In the embodiment, the end of the fixing structure 30 arranged in the insertion slot 317b can be provided with a limiting protrusion 33 on the outer periphery, and an abutting table is arranged at the slot of the insertion slot 317b. When the fixing structure 30 is lifted, the limiting protrusion 33 and the abutting table can be abutted to limit the connection between the fixing structure 30 and the connecting piece 31, so as to prevent the fixing structure 30 from being pulled out of the insertion slot 317b, and to ensure the stable operation of the fixing assembly 100. The end face of the fixing structure 30 facing the exhaust hole 313b can also be provided with a sealing member, which can be inserted into the exhaust hole 313b when the fixing structure 30 closes the exhaust hole 313b to further improve the airtight effect, so that the connecting piece 31 can achieve better negative pressure adsorption effect, and the structural stability and reliability of the transport device 1000 are further improved.

When it is necessary to fix the transport device 1000 on the stairs 4000 by using the fixing assembly 100, the driving mechanism 10 drives the fixed structure 30 to drive the two clamping arms 31d to expose on the pile carpet 41 on the stairs 4000 to fold and hold the pile on the carpet 41, realize the connection between the connecting piece 31 and the stairs 4000, and make the transport device 1000 be supported and fixed on the stairs 4000 under the action of the fixing assembly 100.
