[0026] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0027] As shown in Figures 1 to 4 The cage preventing and dumping device according to an embodiment of the present application includes a pallet truck 100, a clamping mechanism 200 and a door lock mechanism 300, and realizes safe transportation of the cage through mechanical clamping and automatic control.

[0028] Specifically, the fork 110 of the pallet truck 100 has a lifting assembly to uniformly distribute the weight of the cage to the fork 100 and the wheels of the cage; wherein the pallet truck 100 adopts an existing electric pallet truck, and a suitable electric forklift model can be selected according to the bearing weight and business requirements. For example, when the cage is fully loaded and the weight is > 1 ton, plus the self-weight of the clamping mechanism 200 is about 150KG, a T20 electric forklift can be selected. The lifting assembly is integrated on the fork 110 of the pallet truck 100, and the lifting assembly is an existing component, such as a hydraulic cylinder or an electric cylinder driven component, so that the fork 110 can be vertically lifted to lift the cage, and through the lifting action, the weight of the cage is uniformly distributed to the fork 110 and the four wheels of the cage, ensuring that the cage is stable during transportation and preventing bumping.

[0029] The clamping mechanism 200 is installed on the wall surface of the pallet truck 100, and the clamping mechanism 200 has at least two symmetrical clamping arms 210, and the symmetrical clamping arms 210 are opened and closed through a moving driving member 220.

[0030] The door locking mechanism 300 is arranged at one end of each clamping arm 210 away from the wall surface of the pallet truck 100, and the door locking mechanism 300 has a door stop 310 and a turnover driving member 320, and the turnover driving member 320 is suitable for driving the door stop 310 to turn over to switch the door stop 310 between a blocking state and a non-blocking state, in the blocking state, the two symmetrical door stops 310 are closed to block the opening of the cage door, and in the non-blocking state, the two symmetrical door stops 310 are opened. That is to say, the door stop 310 is arranged on each clamping arm 210, and the two symmetrical door stops 310 on the two symmetrical clamping arms 210 can be opened or closed under the driving of the respective turnover driving member 320, and when closed, the door stop 310 blocks and limits the cage door, which can avoid the opening of the cage door.

[0031] Therefore, according to the cage anti-toppling device, the clamping mechanism 200 and the door locking mechanism 300 are matched to fix the cage in all directions, eliminate the risk of toppling, collision, and opening of the cage door, and prevent the goods from falling, and the device is suitable for carrying cages, material frames, and flexible materials of different specifications. The cage is stably lifted by the lifting assembly on the conventional pallet truck 100, the weight of the cage is evenly distributed to the four wheels of the cage and the fork 110, the cage is effectively stopped and prevented from being knocked during the carrying process. The device does not need to be manually pushed and pulled during the whole process of carrying the cage, and the cage is fixed in all directions, so as to eliminate the possible safety problems during the carrying process and realize the automation and safety of the cage carrying.

[0032] In some specific embodiments, the opposite surfaces of the symmetrical clamping arms 210 are provided with anti-skid pads 211. Thus, the anti-skid pads 211 can effectively prevent the displacement of the cage. Specifically, in the present embodiment, a pair of symmetrical clamping arms 210 are provided, and a plurality of rubber anti-skid pads 211 are arranged on the inner sides of the clamping arms 210 along the length direction, for increasing the friction and protecting the surface of the cage. The clamping arms 210 can be plate-shaped clamping arms to clamp the cage with a larger area.

[0033] In some specific embodiments, the moving driving member 220 adopts a linear module, such as Figure 4As shown, the linear module includes a screw drive assembly 221, a linear guide rail 222, and a motor 223. The clamping arm 210 is arranged on a slider of the linear guide rail 222, and the screw drive assembly 221 is connected to the slider and the motor 223. The screw drive assembly 221 has a positive and negative screw structure at both ends. The motor 223 drives the screw to rotate, thereby driving the slider on the linear guide rail 222 to move synchronously, so as to clamp and release the clamping arm 210, thereby adapting to different sizes of the cage.

[0034] Further, the clamping mechanism 200 further includes a bracket 230, and the linear module is arranged on the bracket 230. The bracket 230 is adapted to be mounted on the wall surface of the pallet truck 100. Specifically, during the mounting process, the bracket 230 including the linear module is first mounted on the wall surface of the pallet truck 100. The bracket 230 can be mounted on the wall surface of the pallet truck 100 by bolts, so as to ensure that the clamping mechanism 200 is rigidly connected with the pallet truck as a whole. Then, the two clamping arms 210 are mounted on the linear module. The clamping arms 210 are driven by the power source provided by the motor 223 through the screw drive assembly 221, so as to realize the clamping action, prevent the cage from tilting to the surrounding, and effectively prevent the displacement of the cage by the rubber non-slip pad 211. The motor 223 can be a servo motor.

[0035] In some specific embodiments, the turnover driving member 320 includes an electric cylinder 321, a base 322, and a rotating shaft 323. The side surface of the door stop 310 is connected to the rotating shaft 323, the rotating shaft 323 is rotatably arranged on the base 322, and the electric cylinder 321 is connected to the rotating shaft 323 to drive the rotating shaft 323 to rotate and drive the door stop 310 to turn over 90° to be closed. That is, the piston rod of the electric cylinder 321 is connected to the rotating shaft 323 to drive the rotating shaft 323 to rotate and drive the door stop 310 to turn over 0-90°, so as to realize the closing (blocking state) and opening (non-blocking state) of the symmetrical door stop 310. When the door stop 310 is closed, it is at a right angle of 90°, which is fixed by the locking force of the electric cylinder 321, so as to prevent the cage door from being accidentally opened during the transportation process and prevent the goods from falling.

[0036] In some specific embodiments, a controller is further included, and the controller is connected to the moving driving member 220 and the turnover driving member 320. Specifically, the controller is integrated into the operation panel of the pallet truck 100 and is signal-connected to the servo motor 223 and the electric cylinder 321. The controller adopts an existing PLC controller, which will not be described in detail here.

[0037] In use, when the tray carrier 100 takes the cage trolley, the lifting assembly lifts the cage trolley to a set height, the handle switch is operated, the controller signal is triggered, the servo motor 223 is driven to perform the forward rotation / turnover action, the servo motor 223 gear drives the screw rod to rotate, the screw rod is provided with positive and negative screw structures at two ends, the clamping arm 210 is clamped / loosened through the sliding block to clamp the cage trolley. Then, the turnover handle switch is operated, the controller outputs a signal to the electric cylinder relay after recognizing the closing signal, the electric cylinder 321 is actuated after being powered, and the door stop 310 is actuated to realize turnover closing and block the cage trolley door.
