Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, and more specifically, to a lifting conveying platform. Background Technology

[0002] With the rapid development of computer vision and machine learning technologies, and the emergence of various high-precision sensors, a wide range of automated loading and unloading robots have appeared. For robots handling cardboard boxes, a limited working space is a disadvantage when loading and unloading within the same box. To achieve the function of conveying cardboard boxes within the box, the mechanical structure needs to be exceptionally long to extend into the box. However, an excessively long conveyor platform can affect the robot's movement and turning when not in operation. Therefore, it is necessary to design a deformable conveyor structure, at least capable of reducing its length when necessary. Using a liftable conveyor platform in some structures can help reduce the robot's length when not in operation. For example, part of the platform can be raised to create a storage space at the bottom, and another part of the platform can be moved into the storage space at the bottom, thereby reducing the overall length of the conveyor platform.

[0003] Regarding liftable conveyor platforms, existing technologies have conducted relevant research. For example, Chinese patent CN215401323U discloses a movable lifting conveyor belt, which achieves lifting adjustment of the conveyor mechanism by setting lifting mechanisms on each support leg at the bottom of the conveyor mechanism. However, this requires the use of multiple lifting mechanisms, and it is difficult to control the synchronous lifting of each lifting mechanism. Another example is Chinese patent CN116161379A, which discloses a liftable adjustable conveyor belt. A telescopic support rod is set in the middle of the bottom of the conveyor mechanism. The telescopic support rod pushes the conveyor mechanism up and down through a lifting plate. However, its use of a single telescopic support rod results in poor stability. Therefore, it is necessary to design a new lifting conveyor platform. Utility Model Content

[0004] This invention provides a lifting and conveying platform to overcome the problem that existing conveying platforms are difficult to achieve good lifting synchronization and stability.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a lifting and conveying platform, comprising: a frame, a lifting and adjusting mechanism, and a conveyor belt assembly. The frame is connected to the lifting and adjusting mechanism, and the lifting and adjusting mechanism is connected to the conveyor belt assembly. The lifting and adjusting mechanism includes a lifting power source, a linkage shaft, a transmission shaft, and lifting components. The output end of the lifting power source is drivenly connected to the linkage shaft. A pair of transmission shafts are rotatably connected to the frame and disposed on both sides of the conveyor belt assembly. The linkage shaft is drivenly connected to the pair of transmission shafts. Multiple lifting components are spaced apart along the length of each transmission shaft. Each lifting component is drivenly connected to the transmission shaft, and the moving end of each lifting component is connected to the conveyor belt assembly.

[0006] In the technical solution of this utility model, the lifting power source drives the conveyor belt assembly to move up and down sequentially through a linkage shaft, a transmission shaft, and lifting components. The lifting power source simultaneously drives the transmission shafts on both sides via the linkage shaft, ensuring the synchronicity of power transmission on both sides of the conveyor belt assembly. Transmission shafts are respectively installed on both sides of the conveyor belt assembly, and these transmission shafts are connected to the conveyor belt assembly through multiple spaced-apart lifting components, ensuring the stability of the conveyor platform's lifting mechanism. The lifting conveyor platform using this solution can be raised to create a space below, accommodating other parallel conveying components. This reduces the length of the conveying device when the loading / unloading robot is not in operation, facilitating the robot's movement and turning.

[0007] Furthermore, the system also includes a guide assembly having a movable end capable of moving along the lifting direction of the conveyor belt assembly. The fixed end of the guide assembly is connected to the frame, and the movable end is fixedly connected to the conveyor belt assembly. In this solution, the guide assembly guides the lifting movement of the conveyor belt assembly, improving the stability of the lifting motion.

[0010] Furthermore, the frame is provided with a first limiting member, and the lifting rack is provided with a second limiting member. The first limiting member and the second limiting member abut against each other when the lifting rack is at the end of its stroke. In this solution, by the abutting of the first limiting member and the second limiting member, the end position of the lifting rack's stroke is restricted, thereby ensuring that each lifting rack is at a uniform height.

[0011] Furthermore, the conveyor belt assembly includes a conveyor belt bracket, a conveyor belt motor, a conveyor belt body, and a conveyor belt roller.

In this design, the conveyor belt bracket serves as a mounting support. The conveyor belt motor drives the conveyor belt roller to rotate, and the conveyor belt roller drives the conveyor belt body to move, thereby realizing the transmission function of the conveyor belt assembly.

[0012] Furthermore, the conveyor belt assembly is equipped with a guardrail assembly, which is adjustablely connected to the conveyor belt assembly along its width direction. In this solution, the width of the goods can be preset using the guardrail assembly, effectively preventing the goods from leaving the conveyor line.

[0013] Furthermore, the guardrail assembly includes a guardrail body, an adjusting bracket, an adjusting rod, and an adjusting knob. The adjusting bracket is fixedly connected to the conveyor belt bracket, the adjusting rod is fixedly connected to the guardrail body, and the adjusting rod is movably connected to the adjusting bracket.

In this solution, by changing the position of the adjusting rod in the adjusting bracket and then fixing the adjusting rod in the adjusting bracket using the adjusting knob, the position of the guardrail body can be easily adjusted to adapt to the width of the goods.

[0014] Furthermore, the drive shaft includes multiple shaft segments and universal joints, with adjacent shaft segments connected by universal joints. In this design, multiple shaft segments are connected by universal joints, which not only ensures power transmission over a long drive shaft but also facilitates assembly.

[0015] Furthermore, the linkage shaft is arranged along the width direction of the conveyor belt assembly, and the drive shaft is arranged along the length direction of the conveyor belt assembly. Both ends of the linkage shaft are connected to the drive shaft via first transmission components. In this solution, by providing first transmission components at both ends of the linkage shaft, the drive shafts at both ends are driven synchronously, and the drive shaft and linkage shaft are indirectly connected via the first transmission components.

[0016] Furthermore, the lifting power source is connected to the linkage shaft via a second transmission assembly. In this solution, the lifting power source and the linkage shaft are indirectly connected via the second transmission assembly.
