Description

Technical Field

[0001] The utility model relates to the technical field of logistics handling equipment, in particular to a rotating self-positioning platform of a logistics vehicle. Background Art

[0002] When a logistics vehicle is used to transfer large-volume goods or products in a warehouse or workshop, there are usually different requirements for the direction of the goods or products between the loading point and the unloading point to facilitate loading and unloading. Therefore, the logistics vehicle is required to have the function of automatically rotating the goods. However, by using the rotating self-positioning platform, the material vehicle can use the rotating self-positioning platform to more easily complete the handling of goods.

[0003] In traditional logistics vehicles, the lifting device in the material cart is controlled by a single-chip microcomputer to lift and move the goods. Traditional logistics vehicles have the following problems: the goods cannot be rotated automatically, and the direction of the goods needs to be adjusted manually, which increases the complexity and time of loading and unloading operations, resulting in reduced loading and unloading efficiency. When handling large-volume goods, it may increase loading and unloading costs, reduce efficiency, and increase the risk of damage to goods. To this end, a rotating self-positioning platform for logistics vehicles is proposed. Utility Model Content

[0009] It also includes a single chip microcomputer, which is arranged on the left side of the bottom wall of the vehicle body, and the output end of the single chip microcomputer is electrically connected to the input end of the motor.

[0010] Furthermore, it also includes a battery, which is arranged at the right end of the bottom wall of the vehicle body, and the output end of the battery is electrically connected to the input end of the single-chip microcomputer to facilitate power transmission.

[0011] Furthermore, the infrared receiver is arranged at the rear end of the bottom wall of the vehicle body, and the infrared receiver is bidirectionally electrically connected to the single-chip microcomputer, so as to facilitate external control.

[0012] Furthermore, it also includes a display, which is arranged on the left side of the vehicle body. The input end of the display is electrically connected to the output end of the single-chip microcomputer, so that the current real-time status of the vehicle body can be observed.

[0013] Furthermore, the rotating mechanism also includes a motor 1, a worm wheel and a worm. The motor 1 is installed on the left end of the bottom wall of the vehicle body through a fixed seat.

The input end of the motor 1 is electrically connected to the output end of the single-chip microcomputer, which can accurately locate the goods and make accurate direction adjustments.

[0014] Furthermore, the positioning mechanism includes a splint, a slide groove and a bayonet. The slide groove is opened in the middle of the bottom wall of the vehicle body. The front and rear ends of the inner wall of the slide groove are respectively slidably connected with splints. The relative inner sides of the two splints are provided with bayonet holes.

The output shaft of motor 2 drives the bidirectional screw to rotate at a specific speed and direction. The characteristics of the bidirectional screw will cause the two splints to approach the center of the rotating shaft at the same time. As the bidirectional screw rotates, the two splints slide along the inner wall of the slide groove and gradually approach the center of the rotating shaft. When the bayonet holes on the two splints contact the outer surface of the rotating shaft, due to the action of friction, the splints will continue to squeeze toward the center of the rotating shaft and gradually clamp the rotating shaft. After the splints clamp the rotating shaft, the friction force can control the further rotation of the rotating shaft and finally stop the rotation, so as to realize the positioning of the rotating shaft and the position of the goods on the placement plate, ensure that the goods are accurately positioned at the required position, and avoid the offset phenomenon caused by inertia.

[0029] The working principle of the utility model is as follows:

[0030] When it is necessary to transport goods, an instruction is issued through an external infrared generator, and a pulse signal is transmitted to the single-chip microcomputer 8 through the infrared receiver 10. After the single-chip microcomputer 8 makes a judgment, it controls the internal electrical appliances, and the single-chip microcomputer 8 regulates the storage battery 7 to transmit power to the motor 11. After receiving the signal, the single-chip microcomputer 8 makes a judgment and regulates the operation of the motor 11. The output shaft of the motor 11 drives the wheel hub 2 4 to rotate forward or reverse to move forward and backward, and drives the wheel hub 1 1 to rotate through the pin shaft until the vehicle body 3 is driven to move to the designated location;

[0031] Then the goods are placed on the placement plate 58. When the goods or products with larger volumes are transported between the loading point and the unloading point, different requirements are placed on the direction to facilitate loading and unloading. Therefore, the single chip microcomputer 8 is used to control the operation of the motor 52. The output shaft of the motor 52 drives the worm 56 to rotate. The worm 56 rotates by meshing with the worm wheel 55, thereby driving the rotating shaft 54 ​​to rotate. The rotating shaft 54 ​​drives the placement plate 58 and the goods on the placement plate 58 to rotate a certain angle to adjust the direction of the goods. The worm gear transmission system has a high transmission accuracy, which can accurately locate the goods and make accurate direction adjustments to ensure that the goods are placed accurately. At the same time, when the placement plate 58 rotates, the pillars 53 evenly distributed on the lower surface slide in the annular slide 51, thereby stabilizing the goods and preventing the goods from sliding or tilting during the rotation process. Ensure that the goods remain stable during the loading and unloading process, thereby improving the efficiency and safety of logistics handling.

[0032] When the rotation angle needs to be stopped, the operation of the motor 1 52 is first stopped through the single chip microcomputer 8, and then the operation of the motor 2 66 is controlled by the single chip microcomputer 8. The output shaft of the motor 2 66 drives the bidirectional screw 64 to rotate at a specific rotation speed and direction. The characteristics of the bidirectional screw 64 will make the two clamps 61 approach the center of the rotating shaft 54 ​​at the same time. As the bidirectional screw 64 rotates, the two clamps 61 slide along the inner wall of the slide groove 62 and gradually approach the center of the rotating shaft 54. When the bayonet 67 on the two clamps 61 contacts the outer surface of the rotating shaft 54, due to the friction Under the effect of the clamping plate 61, the clamping plate 61 will continue to squeeze toward the center of the rotating shaft 54 ​​and gradually clamp the rotating shaft 54. After the clamping plate 61 clamps the rotating shaft 54, the friction force can control the further rotation of the rotating shaft 54 ​​and finally stop the rotation, so as to realize the positioning of the rotating shaft 54 ​​and the cargo on the placement plate 58, ensure that the cargo is accurately positioned at the required position, avoid the deviation caused by inertia, and then load and unload the cargo. The real-time status of the current vehicle body 3 can be observed through the display 9, including the current position, speed, battery 7 power and other information.
