[0026] Example
[0027] See also Figures 1 to 4As shown, this embodiment provides a trolley device 1 for driving a material cart 2 to pass through an elevator 3, and the trolley device 1 includes a ground rail 11 and a traction assembly 12. The ground rail 11 is arranged below the elevator 3, and the material cart 2 moves along the ground rail 11 and passes through the elevator 3. The traction assembly 12 includes a clamping member 13 and a moving member 14, the moving member 14 is spaced apart from the elevator 3, the clamping member 13 is arranged on the moving member 14, the clamping member 13 protrudes from the moving member 14 toward the ground rail 11, and the clamping member 13 is detachably connected to the material cart 2. When the clamping member 13 is connected to the material cart 2, the moving member 14 is used to drive the clamping member 13 to move the material cart 2 along the ground rail 11.
[0028] The trolley device 1 provided in this embodiment allows the material cart 2 to pass through the bottom of the elevator 3 by setting a ground guide rail 11. The moving part 14 is set at a distance from the elevator 3. The clamping part 13 protrudes from the moving part 14 toward the ground guide rail 11, so that the clamping part 13 does not collide or interfere with the elevator 3 during the movement, so that the moving part 14 pulls the clamping part 13 to move and the material cart 2 moves along the ground guide rail 11.
[0029] In a possible implementation, the moving member 14 includes a frame 141, a slide 145 and a motor 147. The slide 145 is slidably disposed on the frame 141. The motor 147 and the clamping member 13 are fixed to the slide 145. The motor 147 is used to drive the slide 145 to move along the frame 141.
[0030] In this embodiment, the motor 147 is a servo motor, and the motor 147 drives the slide plate 145 so that the clamping member 13 drives the trolley 2 to move. The trolley 2 is driven to the position of the elevator 3 by the AGV trolley, and then the motor 147 replaces the AGV trolley to provide power for the trolley 2. When the trolley 2 moves under the elevator 3, the trolley 2 and the elevator 3 interact with each other, for example, the elevator 3 takes away the material on the trolley 2 during the movement of the trolley 2. The trolley 2 is moved by the motor 147, so that the trolley 2 and the elevator 3 work in coordination.
[0031] In a possible implementation, the frame 141 includes a base 142 , a rack 143 and a slide rail 144 , the rack 143 and the slide rail 144 are fixed to the base 142 , the slide plate 145 is slidably connected to the slide rail 144 , and the rack 143 is engaged with an output shaft 1471 of the motor 147 .
[0032] In this embodiment, the output shaft 1471 of the motor 147 passes through the slide plate 145, and the output shaft 1471 is provided with a gear 1472, which is meshed with the rack 143 to improve the accuracy of the motor 147 controlling the movement of the slide plate 145, thereby improving the position accuracy of the clamping member 13 driving the trolley 2 to move. The trolley device 1 is meshed with the output shaft 1471 of the motor 147 through the rack 143 to improve the accuracy of the motor 147 driving the trolley 2 to move, which is conducive to accurately controlling the moving speed and moving distance of the trolley 2, so that the trolley 2 and the elevator 3 work in coordination.
[0033] In a possible implementation manner, the bottom of the slide plate 145 has a sliding block 146 , and the sliding block 146 cooperates with the sliding rail 144 .

A plurality of sliders 146 are evenly arranged at the bottom of the slide plate 145, and the plurality of sliders 146 cooperate with the two slide rails 144 respectively to improve the stability of the slide plate 145 when moving.
[0035] In a possible embodiment, the movable part 14 also includes a limit switch 148, which is disposed on the frame 141. The limit switch 148 is electrically connected to the motor 147. The limit switch 148 is used to transmit an induction signal to the motor 147 when sensing the slide plate 145 to slow down or stop the motor 147.
[0036] In a possible implementation, the moving member 14 further includes a limit block 149 , which is fixed to the frame 141 . The limit block 149 corresponds to the slide plate 145 , and is used to stop the slide plate 145 from moving.
[0037] In this embodiment, when the slide plate 145 moves to a position close to the limit switch 148, the output shaft 1471 of the motor 147 slows down or stops rotating, and the slide plate 145 moves to a position in contact with the limit block 149 and stops moving.
[0038] In a possible embodiment, the clamping member 13 includes a clamping jaw 131 and a signal switch 132. The clamping jaw 131 is used to clamp the trolley 2. The signal switch 132 is arranged toward the opening of the clamping jaw 131. The signal switch 132 is used to send a signal to the moving member 14 to open the moving member 14 when it senses that the trolley 2 is clamped in the clamping jaw 131.
[0039] In this embodiment, the signal switch 132 is electrically connected to the motor 147. When the signal switch 132 senses that the trolley 2 is clamped in the clamp 131, it sends a sensing signal to the motor 147, so that the slide plate 145 drives the clamp 131 to move, so that the clamp 131 drives the trolley 2 to pass under the elevator 3. The signal switch 132 is used to sense whether the clamp 131 clamps the trolley 2. When the trolley 2 is separated from the clamp 131 during the movement, the motor 147 stops working.
