Description

Technical Field

[0001] The present invention relates to the technical field of transportation equipment, and particularly to an intelligent short-distance transportation robot. Background Art

[0002] In modern industrial production, logistics warehousing and other fields, short-distance cargo transportation, as a high-frequency and key operation link, its efficiency and safety directly affect the overall efficiency of production logistics. At present, traditional short-distance cargo transportation still mainly relies on manual handling methods. However, this method has significant limitations: First, the efficiency of manual handling is relatively low, making it difficult to meet the large-scale and high-intensity production logistics requirements; Second, workers are prone to fatigue during long-term operations, resulting in a gradual decline in work efficiency, further exacerbating the contradiction between production capacity and demand. In recent years, with the continuous development of intelligent robot technology, its application in the field of logistics transportation has become increasingly widespread, and many enterprises have begun to introduce intelligent transportation equipment to replace manual labor to complete cargo transportation tasks.

[0003] However, there are still some deficiencies in the design of current intelligent transportation robots: First of all, existing transportation robots generally lack a center-of-gravity adjustment structure. When transporting objects with an offset center of gravity, they are extremely prone to tipping, especially when performing turning maneuvers, the risk of tipping increases significantly, which may further lead to damage to the goods; Secondly, transportation robots lack an effective anti-tipping structure for goods. When the robot makes a turning operation, the goods are prone to tipping under the action of centrifugal force. If the tipping angle is too large, the goods will fall, causing unnecessary economic losses. Summary of the Invention

Then, select a suitable movable frame 301 according to the characteristics of the goods such as specifications and weight. Lap the side rod 3011 at the outer end of the movable frame 301 in the lap groove 2012 at the upper end of the support frame 201, so that the telescopic block 1041 on the support module 104 supports the movable frame 301. At the same time, rotatably install the bearing plate 401 above the movable frame 301, so that both ends of the bearing plate 401 are in contact with the induction module 3031, and both sides are against the support springs 3032. If the support module 104 is not needed, the telescopic rod 1031 can be extended from the movable groove 103 to support the lower end of the movable frame 301 to prevent the movable frame 301 from swinging left and right. Then, place the goods on the bearing plate 401, insert the insertion rod 4031 into the circular hole at the side end of the movable rod 4021, and drive the movable rod 4021 to slide in the chute 402 by pulling the clamping plate 403 to adjust the position of the clamping plate 403.

After loading the goods, set an instruction for the vehicle body 101, and the vehicle body 101 transports the goods. During the transportation process, when the vehicle body 101 turns or the goods tilt due to other factors, the pressure received by the induction module 3031 in the tilting direction changes. This pressure change signal is transmitted to the support module 104 in real time. The support module 104 responds quickly, adjusts the telescopic degree of the two telescopic blocks 1041 by controlling the internal electric rod. The telescopic block 1041 penetrates the communication hole A202 of the support frame 201 to support and adjust the movable frame 301, driving the movable frame 301 to make corresponding tilting adjustments, suppressing the tilting trend of the goods and reducing the risk of the goods falling. When the goods are transported to the designated position, release the clamping of the goods by the clamping plate 403 and unload the goods from the bearing plate 401, thus completing the transportation work of the goods.
