[0067] Specifically, the first X-direction running driving wheel 320 is arranged on the wheel shaft 326 through a tightening sleeve 325, and the other wheels all adopt the same structure.

[0069] In summary, the present application includes a four-way vehicle running mechanism 3, a four-way vehicle top lifting and reversing mechanism 2, an electronic clutch 212, 324, a right-angle double-output shaft reducer 210 and a commutator 205, etc.

[0070] In the present application, the reducer uses a right-angle double-output shaft reducer 210, with one power input and two power outputs in different directions, one of which is connected to the four-way vehicle running mechanism 3 and connected using the running electronic clutch 324, and the other output shaft is connected to the four-way vehicle reversing and lifting mechanism 2 and connected using the lifting electronic clutch 212. At the same time, the commutator 205 is used in the reversing and lifting mechanism 2 to output power to the first lifting gearbox 203 and the second lifting gearbox 206 to complete the reversing and lifting. The right-angle double-output shaft reducer 210 is selected to replace the two mechanisms using two drive motors 209 to provide power, saving the layout space of one drive motor 209 and also saving costs.

[0071] A running electronic clutch 324 and a lifting electronic clutch 212 are installed at the two output shafts of the right-angle double-output shaft reducer 210, respectively, and are connected to the four-way vehicle running mechanism 3 and the four-way vehicle lifting mechanism 2 respectively. The separation and closing of the clutch are controlled by the clutch power-on and power-off states, thereby controlling the power output of the two mechanisms respectively.

[0072] Working principle of four-way vehicle travel:

[0073] like Figure 5 , Figure 6 , Figure 7 As shown, the four-way vehicle is powered by a drive motor 209, the drive motor 209 and the total output gearbox 321 are connected via a right-angle double-output shaft reducer 210 and a running electronic clutch 324, while the output shaft at the other end of the right-angle double-output shaft reducer 210 and the commutator 205 are connected via a lifting electronic clutch 212, the running electronic clutch 324 and the lifting electronic clutch 212 are both normally closed, that is, when the electronic clutch is powered on, the clutch is disengaged, and when the electronic clutch is powered off, the clutch is closed.

[0074] When the four-way vehicle needs to move, the lifting electronic clutch 212 in the lifting and reversing mechanism 2 of the four-way vehicle is in an energized state, and the clutch is disengaged. At this time, the right-angle double-output shaft reducer 210 is disconnected from the commutator 205, and the output shaft of the right-angle double-output shaft reducer 210 rotates while the commutator 205 shaft does not rotate, and the power is not transmitted to the lifting and reversing mechanism 2 of the four-way vehicle; at this time, the running electronic clutch 324 in the running mechanism 3 of the four-way vehicle is in a de-energized state, and the clutch is closed. At this time, the output shaft of the right-angle double-output shaft reducer 210 is connected to the total output gearbox 321, and the driving power is transmitted to the total output gearbox 321.

[0075] The driving power is transmitted to the X-direction driving wheel through the internal gear meshing transmission of the total output gear box 321, and is transmitted to the running gear box 306 through the running transmission shaft 323, and finally transmitted to the third X-direction running driving wheel 305 and the fourth X-direction running driving wheel 307 through the internal gear meshing transmission of the running gear box 306. When the four X-direction running driving wheels rotate and run on the track, the four X-direction running driven wheels are driven to rotate and run together, so that the four-way vehicle can run in the X direction.

[0076] The driving power outputted by the total output gearbox 321 is transmitted to the first lifting travel gearbox 202 via the first retractable cross universal coupling 319, and then transmitted to the first Y-direction travel driving wheel 301 and the second Y-direction travel driving wheel 302 via the internal gear meshing transmission of the first lifting travel gearbox 202; similarly, the driving power outputted by the total output gearbox 321 is transmitted to the second lifting travel gearbox 208 via the second retractable cross universal coupling 318, and then transmitted to the third Y-direction travel driving wheel 313 and the fourth Y-direction travel driving wheel 314 via the internal gear meshing transmission of the second lifting travel gearbox 208. When the four Y-direction travel driving wheels rotate and travel on the track, they drive the four Y-direction travel driven wheels to rotate and travel together, so that the four-way vehicle can travel in the Y direction.

[0077] Working principle of four-way roof lifting and reversing:

[0078] like Figure 4 , Figure 5 , Figure 6 As shown, when the four-way vehicle needs to be lifted and reversed, the lifting electronic clutch 212 in the lifting and reversing mechanism 2 of the four-way vehicle is in a power-off state, and the clutch is closed. At this time, the right-angle double-output shaft reducer 210 is connected to the commutator 205, and the output shaft of the right-angle double-output shaft reducer 210 rotates to drive the commutator 205 shaft to rotate, and the driving power is transmitted to the lifting and reversing mechanism 2 of the four-way vehicle. At this time, the running electronic clutch 324 in the running mechanism 3 of the four-way vehicle is in a power-on state, and the clutch is disconnected. At this time, the output shaft of the right-angle double-output shaft reducer 210 is disconnected from the total output gearbox 321, and the driving power is not transmitted to the total output gearbox.

[0079] After the driving power is reversed inside the commutator 205, it is transmitted to the first lifting gear box 203 and the second lifting gear box 206 through the lifting gear box transmission shaft 204. The first lifting gear box 203 is connected to the first lifting beam 201 through the lifting cam 211. Similarly, the second lifting gear box 206 is also connected to the second lifting beam 207 through the lifting cam 211. The driving power drives the four lifting cams 211 to rotate through the internal gear meshing transmission of the first lifting gear box 203 and the second lifting gear box 206. When the lifting cams 211 rotate, the first lifting beam 201 and the second lifting beam 207 on both sides will be driven to move up and down. When the two lifting cams 211 on the same side rotate, the rotation directions are opposite to offset the horizontal force caused by the rotation of the lifting cams 211, so as to avoid horizontal displacement of the first lifting beam 201 and the second lifting beam 207.

[0080] Because the four Y-direction driving wheels are connected to the first lifting beam 201 and the second lifting beam 207 respectively through the first lifting gear box 202 and the second lifting gear box 208, and the four Y-direction driven wheels are also respectively installed on the first lifting beam 201 and the second lifting beam 207. When the four lifting cams 211 rotate to drive the first lifting beam 201 and the second lifting beam 207 to move up and down, the four Y-direction driving wheels and the four Y-direction driven wheels will also move up and down together.

[0081] When the four Y-direction driving wheels and the four Y-direction driven wheels move downward, they will replace the four X-direction driving wheels and the four X-direction driven wheels to contact the track surface, realizing the direction switching of the four-way vehicle from X-direction running to Y-direction running.

[0082] When the four Y-direction driving wheels and the four Y-direction driven wheels move upward, the four X-direction driving wheels and the four X-direction driven wheels will contact the track surface, realizing the direction switching of the four-way vehicle from Y-direction running to X-direction running.

[0083] When the first lifting beam 201 and the second lifting beam 207 continue to move upward, the four X-direction driving wheels and the four X-direction driven wheels are still in contact with the track surface, and the rising first lifting beam 201 and the second lifting beam 207 will lift the goods on the four-way vehicle shelf to realize the lifting function of the four-way vehicle.

[0084] like Figure 8The figure shows the basic structure of the four-way vehicle rack. When the four-way vehicle is working, it can be divided into three working states according to the position states of the first lifting beam 201 and the second lifting beam 207, namely, a low state, a middle state and a high state. When the four-way vehicle is working in a low position, the first lifting beam 201 and the second lifting beam 207 are lowered to the lowest position. At this time, the four Y-direction driving wheels and the four Y-direction driven wheels are in contact with the track surface, and the four-way vehicle travels on the Y-direction running tracks 405 and 406. When the four-way vehicle reaches the first reversing rail and the second reversing rail, the first lifting beam 201 and the second lifting beam 207 are raised to a middle position. At this time, the four X-direction driving wheels and the four X-direction driven wheels replace the four Y-direction driving wheels and the four Y-direction driven wheels to contact the track surface, and the four-way vehicle completes the reversal. At this time, the four-way vehicle travels on the first and second reversing rails, and then travels to the first and second X-direction running rails and finally reaches directly below the pallet 401. At this time, the first lifting beam 201 and the second lifting beam 207 continue to rise to a high position to lift up the pallet 401 and its cargo. The four-way vehicle completes the lifting and can complete the four-way vehicle's cargo picking task.

[0085] The technical solution of the present application replaces the chain sprocket with a full gear box structure to form a power transmission mechanism, uses an input shaft as the power input, and synchronously drives multiple output shafts to rotate, thereby ensuring the consistency of the movements of the driving wheels and the jacking mechanism in the X and Y directions, and improving the stability of power transmission and the operating capacity of the equipment.

[0086] The gearboxes, the drive motors and the travel wheels are all connected by meshing transmission, which simplifies the design structure while meeting the same functions, thus saving maintenance and labor costs and reducing noise.

[0087] The power of the four-way vehicle running mechanism and the four-way vehicle lifting and reversing mechanism is provided by one motor, which is simpler in design structure, higher in space utilization, cost-saving and more stable in equipment.

[0088] The use of the electronic clutch to control the input of power to the four-way vehicle running mechanism and the four-way vehicle top lifting and reversing mechanism is equivalent to adding a layer of mechanical brake protection device.
