Description

Technical Field

[0001] The utility model relates to the technical field of shuttle vehicles, in particular to a heavy-load RGV trolley. Background Art

[0002] RGV is the abbreviation of Rail Guided Vehicle, also known as rail shuttle trolley. RGV trolley can be used in various warehouses with high-density storage methods. The trolley channel can be designed to be arbitrarily long, which can increase the storage capacity of the entire warehouse. There is no need for a forklift to enter the aisle during operation, making it safer.

[0003] However, most of the existing RGVs have simple structures. When a slightly heavy object is carried on the top, the vehicle body is prone to tilt or shake, which makes the objects transported thereon easily fall, making it inconvenient for users to use. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides a heavy-load RGV trolley, which solves the problem that most of the existing RGV trolleys have a simple structure. When the top of the trolley carries slightly heavy objects, it is easy to cause the body of the trolley to tilt or shake, thereby making the objects transported thereon easily fall off, which is inconvenient for users to use.

[0005] The utility model provides the following technical solutions: a heavy-duty RGV trolley, including active wheels, driven wheels, rails and guide wheels, characterized in that: the active wheels and the driven wheels roll on the rails, the guide wheels are located on both sides of the rails, the driven wheels are located on both sides of the rails, and the rails represent straight tracks and curved tracks. A driving motor is included, which is connected to the active wheels through a transmission shaft arranged thereon and is installed vertically. An outer protective plate is included, an inner protective plate is arranged on the side of the outer protective plate, a brush is arranged between the outer protective plate and the inner protective plate, and a rail is arranged at one end of the upper side of the inner protective plate;

[0006] A ground is provided on the side of the rail, a ditch is opened on the side of the ground, a busbar is provided in the ditch, a frame is provided on the top of the outer protective plate and the inner protective plate, a driving motor is installed on the frame, guide wheels are evenly provided around the bottom end of the driving motor, driven wheels and driven universal wheels are respectively provided on both sides of the bottom end of the frame, a driving wheel is provided at the bottom end of the driving motor, a collector mounting bracket is provided at the bottom end of the driving motor, a collector body is installed on the collector mounting bracket, a sensor is provided on the side of the collector body, and an induction sheet is provided at the bottom end of the sensor.

[0007] Preferred technical solution 1: the driving wheel and the driven wheel slide on the rail, the guide wheels are located on both sides of the rail, and the driven universal wheel moves on the outer protective plate and the inner protective plate.

[0008] This solution enables the driving wheels and driven wheels of the device to run on a curved rail. The two sets of guide wheels are guided by the edges of the rail on both sides and run along the curved rail. The two driven universal wheels run on the protective plate. Compared with other RGVs that rely on two equidistant rails to run, this solution saves costs and simplifies construction difficulty.

[0009] Preferred technical solution 2: The driving motor is connected to the active wheel via a transmission shaft arranged thereon and is installed vertically.

[0010] This solution enables the drive motor to be connected to the active wheel via the transmission shaft and installed vertically, while the swing space required for the drive motor inside the vehicle body is reduced.

[0011] Preferred technical solution three: the drive motor is connected to the active wheel through the transmission shaft, the active wheel swings left and right following the guide wheel and the rail, the drive motor swings following the active wheel, and the collector body swings following the drive motor.

[0012] This solution enables the drive motor to be connected to the active wheel through the transmission shaft, and the active wheel swings left and right following the curvature of the guide wheel and the rail. The drive motor swings along with the active wheel, and the collector body installed on the drive motor swings along with the drive motor, ensuring that the collector body always remains in a normal working state in the busbar during the movement of the RGV.

[0013] Preferred technical solution four: the busbar is installed on the trench, and the outer protective plate, the inner protective plate and the brush are provided on the trench.

[0014] This solution enables the busbar to be installed in a trench, and a protective plate and a brush are provided on the trench, which increases safety and reliability compared to the installation method of the busbar on the ground.

[0015] Preferred technical solution five: the collector body is placed in the trench through the collector mounting bracket and is connected to the busbar.

[0016] This solution enables the collector body installed on the driving motor to be placed inside the trench through the collector mounting bracket and connected to the busbar, and the mounting bracket can swing along with the swing of the driving motor and swing in the gap between the inner and outer protective plates, so that the entire RGV is always equidistant from the rails and the edges of the protective plates during travel.

[0017] Preferred technical solution six: the sensor is located in the ditch.

[0018] This solution enables the sensor installed on the collector mounting bracket to be placed inside the trench, and to swing along with the driving motor to detect the sensor sheet arranged at the bottom of the trench.

[0019] Compared with the prior art, the utility model provides a heavy-duty RGV trolley with the following beneficial effects:

[0020] The utility model provides a frame on the outer protective plate and the inner protective plate, and a driving motor is provided on the frame. The driving motor can drive the active wheels to travel stably along the rails through the driving shaft, and the guide wheels provided on both sides of the rails play a stabilizing and guiding role. The collector body installed on the driving motor can swing with the swing of the driving motor, ensuring that the collector body always remains in normal operation in the busbar during the operation of the RGV, making the heavy objects placed on the frame more stable during transportation, avoiding tilting or shaking of the vehicle body, making the transportation of objects safer and more convenient for users.
