Description

Technical Field

[0001] The utility model belongs to the technical field of RGV vehicles, and in particular relates to a RGV vehicle with stable operation. Background Art

[0002] The RGV (Rail Guided Vehicle) trolley is a logistics equipment that realizes automated transportation based on tracks. Its technical background mainly includes track guidance technology, navigation and positioning technology, electric transmission technology and control system. Track guidance technology is the core of the RGV trolley, which realizes the standardized motion trajectory of the trolley through the track fixed on the ground. The track is usually made of special materials with high strength and stability, which can ensure the stability and precise position control of the trolley. However, the existing RGV trolley upper cargo transport structure has poor stability when loading and unloading goods, which may cause the goods to tip over and roll over during the loading and unloading process. This is mainly related to the center of gravity of the object when loading and unloading goods and the design of related fixing devices. Utility Model Content

[0003] In order to overcome the problem that the existing RGV trolley has poor stability in the upper cargo transport structure when loading and unloading cargo, which causes the cargo to easily tip over and roll over during the loading and unloading process.

[0005] Preferably, the stepper motor of the freight component drives the conveyor belt to rotate, so that the goods on the upper end are transported to the top of the freight component. When unloading the goods, the stepper motor drives the conveyor belt to rotate and drives the goods to move horizontally, thereby completing the smooth loading and unloading of the goods, effectively improving the operating stability, and solving the problem of the existing RGV trolley, because its upper end cargo transport structure has poor stability when loading and unloading goods, which makes the goods prone to tipping and rolling during the loading and unloading transportation.

[0006] Preferably, the RGV trolley assembly includes a trolley bracket, a servo drive motor, rail wheels, a rail stabilizing roller frame, a distance sensor, and a laser sensor; a servo drive motor is arranged inside the trolley bracket; rail wheels are arranged at the four corners of the lower end of the trolley bracket, and the rail wheels are connected to the servo drive motor by transmission.

[0007] Preferably, a track stabilizing roller frame is provided on the outer side of the track wheels, and the track stabilizing roller frame is fixedly connected to the inner wall of the trolley bracket, and a distance sensor is provided on the inner side of the track stabilizing roller frame. The track stabilizing roller frame clamps the outer side of the sliding track, and the distance sensor is used to detect the distance between it and the track, so as to improve the horizontal stability of the track stabilizing roller frame when sliding along the track, and effectively prevent the problem of shaking in the horizontal direction when the RGV trolley assembly slides.

[0008] Preferably, a laser sensor is provided behind the servo drive motor and fixedly connected to the inner wall of the trolley bracket, and the laser sensor is used to identify the distance recognition function behind the entire device.

[0009] Preferably, the freight assembly includes a logistics conveyor rack, a conveyor belt, a stepper motor, a guardrail, and a laser identifier; logistics conveyor racks are arranged on both sides of the upper end of the trolley bracket, and the logistics conveyor racks are fixedly connected to the trolley bracket by bolts; stepper motors are arranged between the two logistics conveyor racks, and the outer casing of the stepper motor is fixedly connected to the inner wall of the logistics conveyor rack by bolts.

[0010] Preferably, a conveyor belt is provided around the periphery of the logistics conveyor rack, and the conveyor belt is transmission-connected to the output end of the stepper motor. When unloading goods, the stepper motor drives the conveyor belt to rotate and drives the goods to move horizontally to unload the goods, thereby completing the function of smooth loading and unloading of goods and effectively improving the operation stability.

[0011] Preferably, a guardrail is provided at the upper end of the logistics conveyor rack, and the guardrail is fixedly connected to the outer shell of the logistics conveyor rack; a laser identifier is provided at the upper end of the guardrail, and the guardrail effectively improves the stability of the goods when moving on the conveyor belt.

[0012] Beneficial effects of the utility model:

[0013] 1. The existing RGV trolley has a poor stability of the upper cargo transport structure when loading and unloading goods, which causes the goods to easily tip over and roll over during the loading and unloading process. The stepper motor of the freight component drives the conveyor belt to rotate, so that the goods on the upper end are transported to the top of the freight component, and when unloading goods, the stepper motor drives the conveyor belt to rotate and drive the goods to move horizontally, thereby completing the smooth loading and unloading of goods and effectively improving the operation stability. This solves the problem of the existing RGV trolley, which has a poor stability of the upper cargo transport structure when loading and unloading goods, causing the goods to easily tip over and roll over during the loading and unloading process;

[0014] 2. Through the setting of the track stabilizing roller frame, the track stabilizing roller frame clamps the outer side of the sliding track to improve the horizontal stability of the track stabilizing roller frame when sliding along the track, and effectively prevents the RGV trolley assembly from shaking in the horizontal direction when sliding.
