Description

Technical Field

[0001] The utility model relates to the technical field of robots, in particular to a stair logistics robot. Background Art

[0002] A robot is a programmable and multifunctional manipulator used to carry materials, parts, tools, or a specialized system with changeable and programmable actions for performing different tasks. At present, in some buildings without elevators, in order to solve the problem of cargo transportation between different floors, some auxiliary devices are often used to replace manual labor. Stair climbing robots are one of them. In the prior art, most stair climbing robots adopt crawler and impeller structures. During the process of climbing stairs, the loading platform will form an inclined angle, which may cause the loaded cargo to slide off the loading platform, causing damage to the cargo and potential danger to the personnel on the scene. Regardless of whether the crawler or impeller structure is adopted, the overall structure is very complex and heavy. After a long time of use, it will cause certain damage to the staircase body, such as scratches and cracks on the surface of the ceramic block, and it requires a large driving power. Now there are patent documents to improve this.

[0003] For example, Chinese patent CN207274808U discloses a stair climbing robot, including a shell, a ground walking mechanism, a main moving foot mechanism, an auxiliary foot mechanism and a control unit; wherein a loading platform is arranged on the top of the shell for placing goods to be moved; the ground walking mechanism is used for ground walking and turning; the main moving foot mechanism includes a first main foot and a second main foot rotatably arranged on both sides of the shell, and a main driving device installed inside the shell, and the auxiliary foot mechanism includes a first auxiliary foot and a second auxiliary foot telescopically arranged at the rear end of the shell, and an auxiliary driving device installed inside the shell. The stair climbing robot provided by the utility model is supported by the main moving foot mechanism and the auxiliary foot mechanism during the process of climbing stairs, and the body rises steadily; when walking on the ground, it is supported by the ground walking mechanism, thereby enabling the loading platform to be in a horizontal state during transportation, and the goods carried are not easy to slide off, and the overall structure is simple and firm, and the carrying capacity is strong.

[0004] Although the above patent is supported by the main motion foot mechanism and the auxiliary foot mechanism, and the body rises steadily; when walking on the ground, it is supported by the ground walking mechanism and can climb stairs well, but the robot will shake in the process of climbing the stairs, and the objects carried by the robot are easy to fall, and there is no limit on the objects, which affects the delivery efficiency of the objects. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a stair logistics robot, which solves the problem that the robot may shake, easily causing objects carried by the robot to fall, and there is no position limit for the objects.

[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: a stair logistics robot, comprising a stair robot body and a accommodating slot opened on the top of the stair robot body, the top of the stair robot body and the front and rear parts of the accommodating slot are provided with strip grooves, the bottom of the inner cavity of the strip groove is provided with a threaded hole, the internal thread of the threaded hole is connected to a threaded rod, a rotating sleeve is rotatably connected to the upper part of the outer surface of the threaded rod, the outer surface of the rotating sleeve is fixedly connected to an extrusion plate, and limiting mechanisms are provided on both sides of the inner cavity of the accommodating slot.

[0007] Preferably, the limiting mechanism includes a limiting plate, and sliding grooves are provided on both sides of the front and rear parts of the inner cavity of the accommodating slot. The interiors of the two front and rear sliding grooves are slidably connected to the front and rear parts of the limiting plate through sliders, and mounting holes are provided on both sides of the inner cavity of the accommodating slot.

[0008] Preferably, a limiting cylinder is fixedly connected to one side of the inner cavity of the mounting hole, a limiting rod is slidably connected to the inside of the limiting cylinder, one end of the limiting rod is fixedly connected to one side of the limiting plate, and a first spring is sleeved between the outer surface of the limiting cylinder and the outer surface of the limiting rod.

[0009] Preferably, a support plate is slidably connected between the front and rear parts of the inner cavity of the accommodating slot, support tubes are fixedly connected around the bottom of the inner cavity of the accommodating slot, and a support rod is slidably connected inside the support tube.

[0010] Preferably, one end of the support rod is fixedly connected to the bottom of the support plate, and a second spring is sleeved between the outer surface of the support tube and the outer surface of the support rod.

[0011] Preferably, one end of the threaded rod is fixedly connected to a handle.

[0012] Beneficial Effects

[0013] The utility model provides a stair logistics robot. Compared with the existing technology, it has the following beneficial effects:

[0014] (1) The utility model uses the force of two first springs to cause the limit cylinder and the limit rod to push the limit plate to move toward the middle, so that the two limit plates clamp the object. At the same time, the threaded rod is rotated to drive the rotating sleeve to move downward. The rotating sleeve will drive the extrusion plate to move downward, so that the extrusion plate squeezes the top of the object. By limiting the two sides and the top of the object, the object transported by the robot can be well limited, thereby ensuring the stability of the robot in transporting the object.

[0015] (2) The utility model uses the force of the second spring to enable the support tube and the support rod to reduce the impact force of the objects on the support plate, thereby effectively protecting the objects transported by the robot. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] It should be noted that, by rotating the threaded rod 5 into the threaded hole 4 and rotating the extrusion plate 7 , the extrusion plate 7 is rotated and lowered into the strip groove 3 .

[0024] Furthermore, in order to facilitate the limiting and fixing of the object in the accommodating slot 2, the limiting mechanism 8 includes a limiting plate 81, and sliding grooves 82 are provided on both sides of the front and rear parts of the inner cavity of the accommodating slot 2.

One end of the limiting rod 85 is fixedly connected to one side of the limiting plate 81, and a first spring 86 is sleeved between the outer surface of the limiting cylinder 84 and the outer surface of the limiting rod 85.

[0025] Furthermore, in order to reduce the impact force of the objects being transported, a support plate 9 is slidably connected between the front and rear parts of the inner cavity of the accommodating slot 2, and a support tube 10 is fixedly connected around the bottom of the inner cavity of the accommodating slot 2.
