[0026] Embodiment 1
[0027] Referring to Figure 1 , a self - balancing motor handling device based on dynamic counterweight is provided, including: wheels 1; a lever 2 rotatably arranged on the wheels 1, a fixing frame 21 arranged on the upper side of one end of the lever 2, and a hanging rod 22 rotatably arranged at one end of the lever 2; a telescopic member 3 fixedly arranged on the fixing frame 21; a counterweight member 4 slidably arranged in the hanging rod 22, and the movement of the telescopic member 3 drives the displacement of the counterweight member 4; when the hanging rod 22 is in an unbalanced state when lifting a heavy object, the telescopic member 3 deforms and displaces based on the force difference on both sides of the hanging rod 22, driving the counterweight member 4 to slide towards the weight - loss side of the hanging rod 22 to restore balance.
[0028] Specifically, in this embodiment, when the hanging rod 22 lifts a heavy object, if an imbalance occurs, the telescopic member 3 deforms and displaces based on the force difference on both sides of the hanging rod 22, driving the counterweight member 4 to slide towards the weightless side to restore balance. Through the linkage of the telescopic member 3 and the counterweight member 4, the automatic balance function is achieved, meeting the stability requirements when handling heavy objects.
[0029] Embodiment 2
[0030] Refer to Figure 2 , what is different from the first embodiment in this embodiment is that the lower surface of the driven plate 32 forms a sealed connection with the upper end of the folding section 331 of the folding tube 33 to prevent air leakage. The driven plate 32 divides the carrier 31 into upper and lower chambers and drives the deformation of the folding tube 33 through sliding. The folding tube 33 compresses or releases the air in the storage chamber 333 through the deformation of the folding section 331 and the straight tube section 332 to achieve the transmission of pressure.
[0031] The driven plate 32 is slidably arranged in the carrier 31 and matches the inner diameter of the carrier 31 to ensure smooth movement without jamming, and can define the displacement direction of the driven plate 32. The lower surface of the driven plate 32 forms a sealed connection with the upper end of the folding section 331 of the folding tube 33 to prevent air leakage. The driven plate 32 divides the carrier 31 into upper and lower chambers and drives the deformation of the folding tube 33 through sliding. The folding tube 33 compresses or releases the air in the storage chamber 333 through the deformation of the folding section 331 and the straight tube section 332 to achieve the transmission of pressure.
[0032] The storage chamber 333 stores air and realizes the pressure transmission between the two sides of the carrier 31 through the communication pipeline 334. The communication pipeline 334 is arranged on the straight tube sections 332 of the folding tubes 33 on both sides to connect the two storage chambers 333, thereby realizing the flow of air.
[0033] Refer to Figure 4The folding tube 33 presents an elliptical ring structure, which has high stability and strength, can withstand greater pressure and deformation, and provides a larger effective volume under the premise of ensuring the normal circulation of air in the tube. The telescopic channel 34 is an axial channel inside the folding tube 33, which is used to accommodate the spring 35 and the traction rope 36. The telescopic channel 34 is opened at the center of the folding tube 33 and is cylindrical. Its diameter is smaller than the longitudinal diameter of the folding tube 33. When the folding tube 33 is extended or compressed, the existence of the telescopic channel 34 ensures that the air in the inner cavity of the folding tube 33 can maintain circulation and avoid airflow blockage caused by deformation. The spring 35 is arranged in the telescopic channel 34 to provide elastic support for the driven plate 32 and assist its reset. The spring 35 can prevent the driven plate 32 from getting stuck or failing during movement. When the driven plate 32 slides downward, the folding section 331 of the folding tube 33 will be compressed, and the spring 35 will be compressed at the same time. When the unbalanced state is released, the elastic restoring force of the spring 35 will push the driven plate 32 to reset, so that the folding tube 33 returns to its original state.
[0034] The traction rope 36 is usually made of high-strength, wear-resistant material, such as steel wire rope or synthetic fiber rope. The traction rope 36 passes through the bottom of the carrier 31, the fixed frame 21 and the hanging rod 22 in sequence. By setting the traction rope 36, the imbalance state can be quickly sensed and the movement can be transmitted. When the left side of the hanging rod 22 loses weight, the traction rope 36 will immediately pull the driven plate 32, triggering the dynamic counterweight mechanism of the device. The pulling of the traction rope 36 causes the driven plate 32 to slide in the carrier 31, driving the deformation of the folding tube 33.
[0035] Example 3
[0036] Reference Figure 2-3 This embodiment is different from the first embodiment in that a guide groove 41 is arranged inside the hanging rod 22 to provide a guide path for the sliding of the counterweight 44. The two side walls of the guide groove 41 are provided with limit bars 42 to limit the movement range of the pull rope 43. The pull rope 43 is passed through the guide groove 41 and surrounds the limit bars 42 on both sides in a "U" shape. Multiple counterweights 44 are equidistantly sleeved on the pull rope 43 and can slide freely along the guide groove 41. When the system detects an unbalanced state, the pull rope 43 will respond immediately. The pull rope 43 will pull the counterweight 44 to move to the weightless side, increase the weight on that side, and thus offset the unbalanced state. This can effectively deal with the imbalance problem caused by bumps or shaking during transportation.
[0037] Furthermore, during transportation, the hanging rod 22 plays a key role in connecting the motor and related components. The two ends of the hanging rod 22 are hooked to the two sets of hanging ears on the motor by hooks, so as to fix the motor and assist in transportation. However, due to the inevitable bumps and shakes during transportation, the unstable state of the motor will break the force balance on both sides of the hanging rod 22.
[0038] When there is a situation of weightlessness on the left side of the hanging rod 22, the balance of the entire system is instantly broken. The hanging rod 22 will tilt downward to the left under the action of gravity. While tilting, the hanging rod 22 will exert a downward pulling force on the traction rope 36 on the left side. This pulling force is transmitted through the traction rope 36 to drive the driven plate 32 connected thereto to move downward;
[0039] The downward movement of the driven plate 32 directly acts on the folding section 331 of the folding tube 33. The driven plate 32 exerts pressure on the folding section 331, causing the folding section 331 to start the folding action. As the folding section 331 folds, the air originally stored in the left storage cavity 333 is squeezed. Under the action of pressure, the air moves through the connecting pipe into the storage cavity 333 in the right folding tube 33;
[0040] When the air surges into the right storage cavity 333, the air pressure in the right storage cavity 333 instantly increases. This increased air pressure forms an upward thrust that acts on the driven plate 32 on the right side. Under the action of this thrust, the driven plate 32 on the right side drives the folding section 331 on the right side to extend upward. At the same time, the upward movement of the driven plate 32 on the right side also drives the pulling rope 43 on the right side to slide in the hanging rod 22. The pulling rope 43 transmits the movement information on the right side to the counterweight 44, pulling the counterweight 44 to move. In the case of weightlessness on one side of the hanging rod 22 caused by the shaking of the motor, the counterweight distribution can be automatically adjusted to restore the balance of the system, ensuring the stability and safety of the transportation process.
[0041] All other structures are the same as those in Embodiment 3.
[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
