The screw nuts 9 are respectively installed on the ball screws 8 on both sides, and are respectively connected to the moving plates 4 on both sides. The ball screws 8 on both sides can be rotated in a controlled manner to drive the loading plate 5 to move along the height direction of the portal frame 1 .

[0037] The embodiment of the present disclosure provides an electric bull for transportation, comprising a portal frame 1, a guide rail 2, a slider 3, a moving plate 4, a loading plate 5, a strip plate 6, a moving wheel 7, a ball screw 8 and a screw nut 9. The portal frame 1 is used to support the entire device.

The sliders 3 are slidably installed on the guide rails 2 on both sides, and together play the role of guiding support. The moving plates 4 are respectively installed on the sliders 3 on both sides, and under the guiding support of the guide rails 2 and the sliders 3 on both sides, the moving plates 4 on both sides can move along the height direction of the portal frame 1. The loading plate 5 is installed between the moving plates 4 on both sides for transporting objects. The strip plates 6 are respectively installed on the opposite side walls of the portal frame 1 along the width direction of the portal frame 1, and the strip plates 6 on both sides are used to support and install the moving wheels 7. The moving wheels 7 are respectively installed at the two ends of the strip plates 6 on both sides, and the four ends of the moving wheels 7 are used to abut against the ground, which plays a role in facilitating the movement of the entire device. The ball screw 8 is rotatably installed on the two opposite side walls of the portal frame 1 along the height direction of the portal frame 1, and can perform rotational motion relative to the two opposite side walls of the portal frame 1. The screw nuts 9 are respectively installed on the ball screws 8 on both sides, and are respectively connected to the moving plates 4 on both sides to convert the rotational motion into linear motion. Among them, the ball screws 8 on both sides can be controlled to rotate to drive the loading plate 5 to move along the height direction of the portal frame 1.

[0038] During use, driven by external force, the ball screws 8 on both sides can rotate simultaneously. Then, under the guiding support of the guide rails 2 and the sliders 3 on both sides, the screw nuts 9 on both sides can drive the moving plates 4 on both sides to move simultaneously. Finally, the loading plate 5 is driven to move along the height direction of the portal frame 1, so as to realize the overall upward movement of the object. Since the portal frame 1 structure is adopted, and the guide rails 2 and the ball screws 8 are located on the opposite side walls of the portal frame 1, a through space can be formed inside the portal frame 1. Longer objects can be placed longitudinally on the loading plate 5, which is convenient for passing through narrow areas during transportation. At the same time, in an open space, longer objects can also be placed horizontally on the loading plate 5 for transportation.

[0039] Optionally, combined Figure 1 As shown, it also includes a rotating shaft 10, a first bevel gear and a second bevel gear. The rotating shaft 10 is rotatably installed on the portal frame 1 along the width direction of the portal frame 1, and is located above the ball screws 8 on both sides along the height direction of the portal frame 1. The first bevel gear is installed on the rotating shaft 10, and is located on both sides of the rotating shaft 10 along the axial direction of the rotating shaft 10. The second bevel gears are respectively installed on the ball screws 8 on both sides, and the second bevel gears on both sides are respectively meshed with the teeth of the first bevel gears on both sides. Among them, the rotating shaft 10 can be controlled to rotate to drive the ball screws 8 on both sides to rotate simultaneously.

[0040] In the disclosed embodiment, a rotating shaft 10, a first bevel gear and a second bevel gear are also included. The rotating shaft 10 is rotatably installed on the portal frame 1 along the width direction of the portal frame 1, and can rotate relative to the portal frame 1. The rotating shaft 10 is located above the ball screws 8 on both sides along the height direction of the portal frame 1 to leave a loading space for the loading plate 5. The first bevel gear is installed on the rotating shaft 10, and is located on both sides of the rotating shaft 10 along the axial direction of the rotating shaft 10, and rotates synchronously with the rotating shaft 10. The second bevel gears are respectively installed on the ball screws 8 on both sides, and respectively drive the ball screws 8 on both sides to rotate. The second bevel gears on both sides are respectively meshed and connected with the teeth of the first bevel gears on both sides to transmit the driving force and change the direction of the force. Among them, the rotating shaft 10 can be controlled to rotate to drive the ball screws 8 on both sides to rotate simultaneously.

[0041] During use, the shaft 10 can rotate under the drive of external force. Then the first bevel gears on both sides are driven to rotate, and through the meshing action between the teeth, the second bevel gears on both sides are driven to rotate. Then the ball screws 8 on both sides are driven to rotate at the same time, and finally the object is moved upward as a whole. Therefore, the ball screws 8 on both sides can be rotated at the same time by the shaft 10 rotating. Thereby reducing the number of driving sources and reducing costs.

[0044] During use, the motor 11 is controlled to work, which can drive the first sprocket to rotate. Through the chain 12, the second sprocket can be driven to rotate. Then the rotating shaft 10 is driven to rotate, and finally the object is moved upward as a whole. In addition, the design that the number of teeth of the first sprocket is smaller than the number of teeth of the second sprocket can reduce the rotation speed, thereby increasing the output torque.

[0045] Optionally, combined Figure 1 As shown, the portal frame 1 comprises a through hole, through which the chain 12 passes.

[0046] In the disclosed embodiment, the portal frame 1 includes a through hole for passing the chain 12.
