[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-4 This utility model provides a technical solution:

[0030] A stair-climbing and transporting robot includes a stair-climbing robot body 1, a horizontal plate 2 fixedly mounted on the stair-climbing robot body 1, a placement plate 3 disposed on the horizontal plate 2, one side of the placement plate 3 rotatably mounted on the horizontal plate 2, an electric telescopic column 4 rotatably mounted on the horizontal plate 2, the output shaft end of the electric telescopic column 4 rotatably mounted on the bottom surface of the placement plate 3, a level instrument disposed on the side of the placement plate 3, a U-shaped frame 5 fixedly mounted on the placement plate 3, a vertical plate 6 disposed at the opening of the U-shaped frame 5, and a driving component 7 for driving the vertical plate 6 to move horizontally on the placement plate 3. The driving component 7 includes a knob 71 rotatably mounted on the side of the placement plate 3, a slide rail 72 opened on the placement plate 3, a lead screw 73 rotatably mounted in the slide rail 72, and a movable block 74 slidably mounted on the slide rail 72. The rotating shaft end of the knob 71 is fixedly mounted to the rotating shaft end of the lead screw 73, the movable block 74 is threadedly connected to the lead screw 73, and the movable block 74 is fixedly mounted to the vertical plate 6.

[0031] In the stair-climbing transport robot, the horizontal plate 2 is used to facilitate the installation and support of the components on it, and the placement plate 3 is used to place the transported items. After the items are placed between the vertical plate 6 and the U-shaped frame, the operator rotates the knob 71 on the side of the placement plate 3. Since the rotating shaft end of the knob 71 is fixedly installed with the rotating shaft end of the lead screw 73 which is rotated in the slide rail 72, the rotation of the knob 71 will drive the lead screw 73 to rotate synchronously. The movable block 74, which is slidably installed on the slide rail 72 and threadedly connected to the lead screw 73, is fixedly installed with the vertical plate 6. When the lead screw 73 rotates, the movable block 74 will move horizontally in the slide rail 72 along the axial direction of the lead screw 73, thereby driving the vertical plate 6 to move horizontally. The distance between the vertical plate 6 and the U-shaped frame can be flexibly adjusted according to the size of the transported items, so that items of different sizes are stably fixed on the placement plate 3, reducing the risk of shaking and slipping of items during the stair-climbing transport process.

[0032] After the item is secured, when the stair-climbing robot 1 climbs the stairs, the stair-climbing robot 1 and the placement plate 3 are in an inclined state. If the level detects that the inclination value of the placement plate 3 is higher than the set threshold, the electric telescopic column 4 is automatically activated. When the output shaft of the electric telescopic column 4 extends, due to the rotational connection between its two ends and the horizontal plate 2 and the placement plate 3 respectively, it will push the placement plate 3 to rotate around its rotation axis with the horizontal plate 2, thereby changing the inclination angle of the placement plate 3 and restoring it to a horizontal state as much as possible, thereby adjusting the levelness of the item.

[0033] This stair-climbing and transporting robot can keep the transported items as horizontal as possible while climbing stairs, reducing the risk of items slipping due to tilting during transport. It also ensures the stability of the robot's center of gravity, effectively improving the stability and safety of item transport.

[0034] Both the vertical plate 6 and the U-shaped frame 5 are covered with pads, which are made of rubber.

[0035] Both the vertical plate 6 and the surface of the U-shaped frame are covered with rubber pads. When the items being transported are placed in the U-shaped frame and clamped by the vertical plate 6, the rubber pads can act as a buffer. During the process of climbing stairs, the robot will inevitably vibrate. With its good elasticity and flexibility, the rubber pads can absorb some of the vibration energy, preventing the items being transported from being damaged due to direct contact and collision with hard surfaces, and further improving the safety of transporting items.

[0036] Slide 72 runs through the placement plate 3 from top to bottom;

[0037] The slide 72 runs through the placement plate 3 from top to bottom, which can prevent debris and other impurities from falling into the slide 72 and accumulating inside, ensuring the stability of the rotation of the lead screw 73 and the sliding of the movable block 74, thereby improving the stability of the adjustment of the vertical plate 6.

[0038] A U-shaped extension plate 8 is slidably disposed on the U-shaped frame 5, and a damping is provided between the U-shaped extension plate 8 and the U-shaped frame 5. A strip extension plate 9 is slidably disposed on the vertical plate 6, and a damping is provided between the strip extension plate 9 and the vertical plate 6.

[0039] The extension length of the U-shaped extension plate on the U-shaped frame and the extension length of the strip extension plate 9 on the vertical plate 6 can be manually adjusted according to the height of the items to be transported, overcoming the damping force. This can better adapt to the transport needs of items of different heights, further reduce the risk of items slipping, and improve the stability of transport.

[0040] The electric telescopic column 4 is provided with at least two symmetrical sets;

[0041] The electric telescopic column 4 is provided with at least two symmetrical sets, which can improve the stability of the angle adjustment of the placement plate 3.

[0042] The level is set to be electric, and a controller is provided on the horizontal plate 2. The controller is electrically connected to the level and the electric telescopic column 4 respectively.

[0043] The level is set to be electric and electrically connected to the controller on the horizontal board 2 and the electric telescopic column 4. During the climbing of the stairs, the level continuously monitors the levelness of the placement board 3 and transmits the levelness data to the controller in real time. Once the level detects that the placement board 3 deviates from the level state, the controller will quickly calculate the amount of telescopic adjustment that the electric telescopic column 4 needs to make based on the received data, and then control the electric telescopic column 4 to perform the corresponding telescopic action.

[0044] Working principle:

[0045] In the stair-climbing transport robot, the horizontal plate 2 is used to facilitate the installation and support of the components on it, and the placement plate 3 is used to place the transported items. After the items are placed between the vertical plate 6 and the U-shaped frame, the operator rotates the knob 71 on the side of the placement plate 3. Since the rotating shaft end of the knob 71 is fixedly installed with the rotating shaft end of the lead screw 73 which is rotated in the slide rail 72, the rotation of the knob 71 will drive the lead screw 73 to rotate synchronously. The movable block 74, which is slidably installed on the slide rail 72 and threadedly connected to the lead screw 73, is fixedly installed with the vertical plate 6. When the lead screw 73 rotates, the movable block 74 will move horizontally in the slide rail 72 along the axial direction of the lead screw 73, thereby driving the vertical plate 6 to move horizontally. The distance between the vertical plate 6 and the U-shaped frame can be flexibly adjusted according to the size of the transported items, so that items of different sizes are stably fixed on the placement plate 3, reducing the risk of shaking and slipping of items during the stair-climbing transport process.

[0046] After the item is secured, when the stair-climbing robot 1 climbs the stairs, the stair-climbing robot 1 and the placement plate 3 are in an inclined state. If the level detects that the inclination value of the placement plate 3 is higher than the set threshold, the electric telescopic column 4 is automatically activated. When the output shaft of the electric telescopic column 4 extends, due to the rotational connection between its two ends and the horizontal plate 2 and the placement plate 3 respectively, it will push the placement plate 3 to rotate around its rotation axis with the horizontal plate 2, thereby changing the inclination angle of the placement plate 3 and restoring it to a horizontal state as much as possible, thereby adjusting the levelness of the item.

[0047] This stair-climbing and transporting robot can keep the transported items as horizontal as possible while climbing stairs, reducing the risk of items slipping due to tilting during transport. It also ensures the stability of the robot's center of gravity, effectively improving the stability and safety of transporting items.

[0048] Both the vertical plate 6 and the U-shaped frame are covered with rubber pads. When the items are placed in the U-shaped frame and clamped by the vertical plate 6, the rubber pads can act as a buffer. During the process of climbing stairs, the robot will inevitably vibrate. The rubber pads, with their good elasticity and flexibility, can absorb some of the vibration energy and prevent the items from being damaged due to direct contact and collision with hard surfaces, thus further improving the safety of item handling.

[0049] The extension length of the U-shaped extension plate on the U-shaped frame and the extension length of the strip extension plate 9 on the vertical plate 6 can be manually adjusted according to the height of the items to be transported, overcoming the damping force. This can better adapt to the transport needs of items of different heights, further reduce the risk of items slipping, and improve the stability of transport.

[0050] The slide 72 runs through the placement plate 3 from top to bottom, which can prevent debris and other impurities from falling into the slide 72 and accumulating, ensuring the stability of the rotation of the lead screw 73 and the sliding of the movable block 74, thereby improving the stability of the adjustment of the vertical plate 6.

[0051] The level is set to be electric and electrically connected to the controller on the horizontal board 2 and the electric telescopic column 4. During the climbing of the stairs, the level continuously monitors the levelness of the placement board 3 and transmits the levelness data to the controller in real time. Once the level detects that the placement board 3 deviates from the level state, the controller will quickly calculate the amount of telescopic adjustment that the electric telescopic column 4 needs to make based on the received data, and then control the electric telescopic column 4 to perform the corresponding telescopic action.

[0052] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
