Description

Technical Field

[0001] The invention relates to a multi-directional mobile RGV for a three-dimensional parking garage, which is mainly used in the field of three-dimensional parking. Background Art

[0002] In the existing stereoscopic parking garage technology, it is basically impossible to use the RGV itself to achieve forward, backward, left and right movement. Most of them use a lateral moving platform to achieve the lateral movement of the RGV. The RGV runs on the lateral moving platform and moves the RGV left and right through lateral movement, thereby distributing the vehicles to different lanes. On the one hand, this method increases the overall equipment cost. On the other hand, due to the need to configure a lateral moving platform, it reduces space utilization and operating efficiency, and increases the risk of equipment failure. Once the lateral moving platform fails, the entire stereoscopic parking garage will stop operating. Another part uses a rotating platform to achieve the change of RGV direction. The rotating platform rotates 90°, and the RGV can achieve lateral movement. This method has similar shortcomings to the above-mentioned lateral moving platform.

[0003] Therefore, the present invention proposes a multi-directional parking RGV system for a three-dimensional parking garage, which can simultaneously realize movement in two directions, lateral and longitudinal. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the present invention proposes a multi-directional mobile parking RGV system for a multi-story parking garage, which can perform lateral and longitudinal movements by itself without relying on other lateral movement mechanisms set up in the parking lot, thereby solving the above-mentioned shortcomings and enabling the RGV to run to different alleys to directly transport vehicles to designated parking spaces or take them off from parking spaces, thereby improving the space utilization and overall reliability of the multi-story parking garage.

[0005] To achieve the above object, the technical solution adopted by the present invention is as follows: The present invention discloses a multi-directional parking RGV system for a three-dimensional parking garage. The RGV system comprises a guide rail structure and an RGV trolley.

[0006] The guide rail structure is arranged on the steel frame structure of the parking garage, and guide rails in two directions are arranged in total. The guide rail structure includes an X-direction guide rail and a Y-direction guide rail.

[0007] The RGV trolley is located on the guide rail, the wheel train of the RGV trolley is in contact with the guide rail, and the auxiliary wheels in the wheel train are used to clamp the moving wheels of the RGV trolley on the track. The RGV trolley runs in the direction of the track to complete the functions of transporting and picking up the car.

[0008] Furthermore, the RGV trolley body is composed of an upper and lower frame, the Y-direction wheel is mounted on the upper frame, and the X-direction wheel is mounted on the lower frame. The X-direction wheel is arranged along the axis of the RGV trolley, and the Y-direction wheel is arranged in the vertical direction of the X-direction wheel; on the X-direction guide rail, the X-direction wheel train works; on the Y-direction guide rail, the Y-direction wheel train works.

[0009] Furthermore, the RGV trolley includes a lifting mechanism, which is connected to the upper frame, and the Y-direction wheel is installed on the upper frame. When the RGV trolley changes from X-direction movement to Y-direction movement, the lifting mechanism drives the RGV upper frame to descend, and then drives the Y-direction wheel system to descend, and the height of the RGV lower frame remains unchanged until the Y-direction wheel system contacts the track and is subjected to force, at which time the X-direction wheel system leaves the track, and the RGV trolley switches from the XY direction; when the RGV trolley changes from the Y-direction movement to the X-direction movement, the lifting mechanism drives the RGV upper frame to rise, and then drives the Y-direction wheel system to rise, and gradually the X-direction wheel system contacts the track and is subjected to force, and the Y-direction wheel system continues to rise until it leaves the track, and the RGV trolley switches from the Y-direction movement to the X-direction movement.

[0010] Furthermore, the RGV system is provided with a fork frame structure in the form of a comb tooth structure for carrying the car. The fork frame and the comb teeth on the parking space are interlaced with each other and matched with the comb teeth on the three-dimensional parking space. The fork frame structure is installed on the RGV upper frame, and the upper frame is connected to the jacking mechanism, thereby driving the fork frame structure to move up and down, so that the car can be parked in the parking space and the RGV can pick up the car from the parking space. When the jacking mechanism moves upward, the fork frame rises and the car is lifted; when the jacking mechanism moves downward, the fork frame descends and the car falls.

[0011] Furthermore, in order to prevent the fork frame from rising and falling at the same height as the Y-axis wheel system, which would interfere with the function and cause the vehicle to fail to function, the vehicle height when the Y-axis wheel system is lowered is set to Y1, the vehicle height when the fork frame is lowered is set to Y2, and the vehicle height when the fork frame is raised is set to Y3. <Y2<Y3。

[0012] Furthermore, the guide rail structure includes a guide rail turning unit, and the guide rail turning structure is located at the connection between the X-guide rail and the Y-guide rail, which is used to reduce the height difference between the guide rails, improve the steering smoothness of the RGV, and reduce equipment loss.

[0013] Furthermore, a busbar device is arranged on the guide rail and connected to a power source; the busbar device comprises a sheath, a conductor and a current receiver.

[0014] Furthermore, a current collector is installed on the body of the RGV trolley; the current collector moves along with the RGV and obtains power from the guide rail in real time and provides it to the RGV trolley, so that the RGV trolley continues to move.

[0015] Beneficial effects of the present invention: The present invention proposes a multi-directional parking RGV system for a three-dimensional parking garage, which can perform lateral and longitudinal movements by itself without relying on other lateral movement mechanisms set up in the parking lot. The RGV can run to different lanes to directly transport vehicles to designated parking spaces or take them out of parking spaces, thereby improving the space utilization and overall reliability of the three-dimensional parking garage.

DETAILED DESCRIPTION

[0017] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0018] Reference Figures 1 to 6 As shown, the present invention is a multi-directional parking RGV system for a three-dimensional parking garage, wherein the RGV system comprises a guide rail structure and an RGV trolley; wherein, The guide rail structure is arranged on the steel frame structure of the parking garage, and guide rails in two directions are arranged in total. The guide rail structure includes an X-direction guide rail and a Y-direction guide rail; The RGV trolley is located on the guide rail, the wheel system of the RGV trolley is in contact with the guide rail, and the auxiliary wheels in the wheel system are used to clamp the moving wheels of the RGV trolley on the track. The RGV trolley runs in the direction of the track to complete the functions of transporting and picking up the car. The size of the RGV designed in the present invention is as follows: Figure 1 As shown, the structure is Figure 2In order to match the size of general vehicles on the market, ensure its transportation function, and reduce its own body size as much as possible, the RGV is 2.1m wide, 4.6m long, and 526mm high.

[0019] like Figure 2 and Figure 3 The figure shows the overall structure of RGV. RGV is equipped with two sets of directional wheel trains, namely the transverse wheel train (X-direction wheel train) and the longitudinal wheel train (Y-direction wheel train). RGV is equipped with front and rear forks, which carry the front and rear wheel trains of the car respectively. Two rows of forks are arranged on the RGV, with forks arranged on the front and rear sides respectively. Two forks are arranged on the front side to fix the front wheels of the car and position them, and multiple rows of forks are arranged in the back row to match a variety of car models. The car is placed on the RGV fork frame. When the car is transported, the fork frame is lifted. After the RGV moves to the fixed parking space, the fork frame falls and the car is parked in the fixed parking space. A lifting mechanism is set on the RGV, which is used to lift the car on the one hand and switch the RGV wheel train on the other hand.

[0020] Furthermore, the body of the RGV trolley is provided with an X-direction wheel and a Y-direction wheel, the X-direction wheel is provided along the axis of the RGV trolley, and the Y-direction wheel is provided in a vertical direction of the X-direction wheel; Furthermore, the RGV trolley includes a lifting mechanism, which is connected to the RGV upper frame, and the Y-axis wheel system is installed on the RGV upper frame. When the RGV trolley changes from X-axis movement to Y-axis movement, the motor drives the lifting mechanism to descend, driving the RGV upper frame to descend, and then driving the Y-axis wheel system to descend, and the height of the RGV lower frame remains unchanged until the Y-axis wheel system contacts the track and is subjected to force, at which time the X-axis wheel system leaves the track, realizing the XY direction switching of the RGV trolley; when the RGV trolley changes from Y-axis movement to X-axis movement, the motor drives the lifting mechanism to rise, driving the RGV upper frame to rise, and then driving the Y-axis wheel system to rise, and gradually the X-axis wheel system contacts the track and is subjected to force, and the Y-axis wheel system continues to rise until it leaves the track, realizing the YX direction switching of the RGV trolley. Figure 3 As shown in the figure, the two sets of wheel trains set in RGV are X-direction and Y-direction wheel trains. To provide good support, RGV is equipped with 6 wheels in the X direction and 8 wheels in the Y direction. To ensure that the corresponding wheels are not interfered when walking in the track, a height difference is set between the two direction wheel trains. When walking in the X direction, the height of RGV is 331.4mm, and when walking in the Y direction, the height of RGV is 357.5mm.

[0021] The lifting mechanism is located at the front and rear sides of the RGV, the motor and the direction changer are located in the middle of the RGV body, the direction changer is connected to the transmission shaft, the transmission shaft is connected to the lifting mechanism through the reduction mechanisms at both ends, the lifting mechanism is connected to the upper frame of the RGV, and the Y-axis wheel system is installed on the upper frame. The motor rotates forward to drive the lifting mechanism to rise, thereby the Y-axis wheel system rises; the motor rotates reversely to drive the lifting mechanism to descend, thereby the Y-axis wheel system descends.

[0022] Furthermore, the RGV system is provided with a fork frame structure in a comb-tooth structure for carrying cars. The fork frame and the comb teeth on the parking space are interlaced and matched with the comb teeth on the three-dimensional parking space. The fork frame structure is installed on the RGV upper frame, and the upper frame is connected to the lifting mechanism, thereby driving the fork frame structure to move up and down, so that the car is parked on the parking space and the RGV picks up the car from the parking space. When the RGV carries the car to the corresponding position, the motor drives the RGV lifting mechanism to descend, the fork frame comb teeth and the parking space comb teeth are interactively matched, the fork frame descends to below the height of the parking space comb teeth, the car is placed on the parking space comb teeth, and the RGV leaves, completing the action of placing the car; when the RGV drives to the position of the car to be transported, the motor drives the RGV lifting mechanism to rise, the fork frame comb teeth and the parking space comb teeth are interactively matched, the fork frame rises to contact the tire to bear force, the fork frame height is higher than the parking space comb teeth, the car is lifted out of the parking space, and the RGV goes to the corresponding parking space to complete the action of lifting the car.

[0023] like Figure 4 The figure shows the principle diagram of the lifting mechanism driving the Y-axis wheel system. The X-axis wheel system and the Y-axis wheel system are independently installed on the upper and lower frames of the RGV. The X-axis wheel system is installed on the lower frame of the RGV, and the Y-axis wheel system is installed on the upper frame of the RGV. The RGV motor is connected to the inverter, one end of the transmission shaft is connected to the inverter through a coupling, and the other end is connected to the lifting mechanism through a reduction mechanism to drive the lifting mechanism to move. The lifting mechanism is connected to the upper frame of the RGV, and the movement of the lifting mechanism drives the upper frame of the RGV to move, thereby driving the Y-axis wheel system to rise and fall.

[0024] like Figure 5 As shown in the figure, it is a schematic diagram of the guide rail structure. Further, when the RGV runs to the connection point of the XY guide rail, the RGV needs to switch the gear train, the Y-axis gear train descends to the Y guide rail, the X-axis gear train rises relatively, the height of the guide rail direction-changing unit matches the height difference between the gear trains and the transition is smooth, and the RGV completes the gear train switching. Figure 6 shown.

[0025] Furthermore, a busbar device is arranged on the guide rail and connected to a power source; the busbar device comprises a sheath, a conductor and a current receiver.

[0026] Furthermore, a current collector is installed on the body of the RGV trolley; the current collector moves along with the RGV and obtains power from the guide rail in real time and provides it to the RGV trolley, so that the RGV trolley continues to move.

[0027] The present invention has many specific application paths. The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements can be made without departing from the principle of the present invention. These improvements should also be regarded as the protection scope of the present invention.
