Description

A self-balancing motor handling device based on dynamic counterweight Technical Field

[0001] This invention relates to the technical field of power equipment maintenance, and in particular to a self-balancing motor handling device based on dynamic counterweight. Background Technology

[0002] In the field of power equipment maintenance, the handling and lifting of medium-sized motors (weighing 125-150 kg) is routine work. However, existing technologies have the following core drawbacks: Traditional handling tools (such as cranes and forklifts) require multiple people to work together to adjust the position of the slings or manually push and pull the equipment to maintain balance. This process relies on the operator's experience and judgment. Especially when the motor's center of gravity is off-center, the equipment is prone to tilting or even tipping over due to delayed adjustments. When the motor is moved, uneven ground or inertial torque caused by turning can lead to equipment damage and personnel safety risks. Summary of the Invention

[0003] In view of the problem that the existing technology requires downtime for maintenance, the present invention is proposed.

The telescopic member moves to displace the counterweight. When the hanging rod becomes unbalanced while lifting a heavy object, the telescopic member deforms and displaces based on the force difference on both sides of the hanging rod, driving the counterweight to slide towards the unbalanced side of the hanging rod to restore balance.

[0006] As a preferred embodiment of the self-balancing motor handling device based on dynamic counterweight described in this invention, the telescopic component includes a set of symmetrically arranged carriers, the carriers being mirror-arranged with the central axis of the fixed frame as the axis of symmetry, and each carrier having a driven plate slidably disposed therein matching the inner diameter of the carrier.

[0008] As a preferred embodiment of the self-balancing motor handling device based on dynamic counterweight described in this invention, each of the carriers is provided with a folded tube, the folded tube comprising an upper folded section and a lower straight tube section.

[0009] As a preferred scheme of the self-balancing motor carrying device based on dynamic counterweight, the storage cavity is arranged in the folding pipe, and the storage cavities of two adjacent folding pipes are connected with each other through a communication pipe.

[0010] As a preferred scheme of the self-balancing motor carrying device based on dynamic counterweight, the folding pipe is in an elliptical ring structure, an axial telescopic channel is formed in the inner periphery of the folding pipe, a spring is arranged in the telescopic channel, and the upper end of the spring is connected with a driven plate; the lower surface of the driven plate is in sealed connection with the upper end of the folding pipe.

[0011] As a preferred scheme of the self-balancing motor carrying device based on dynamic counterweight, a traction rope is arranged on the lower surface of the driven plate in the telescopic channel, and the traction rope is connected with the carrier bottom, the fixing frame and the hanging rod in sequence.

[0012] As a preferred scheme of the self-balancing motor carrying device based on dynamic counterweight, the counterweight comprises a guide groove arranged in the hanging rod, limiting rods arranged on the two side walls of the guide groove, and a pulling rope arranged in the guide groove and winding around the two limiting rods in a "U" shape.

[0013] As a preferred scheme of the self-balancing motor carrying device based on dynamic counterweight, a plurality of counterweight blocks are arranged in the guide groove between the two groups of limiting rods.

[0014] The plurality of counterweight blocks are equidistantly arranged on the pulling rope and can slide in the guide groove.

[0015] As a preferred scheme of the fluid conveying system, the two ends of the pulling rope are connected with the driven plates in the two carriers after penetrating through the upper side wall of the hanging rod and the fixing frame.

[0025] Secondly, the present invention is described in detail with reference to the schematic diagrams.

Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0026] Example 1

[0027] Referring to Figure 1, a self-balancing motor handling device based on dynamic counterweight is provided, including: a wheel 1; a lever 2 rotatably mounted on the wheel 1; a fixed frame 21 mounted on the upper side of one end of the lever 2; a hanging rod 22 rotatably mounted on one end of the lever 2; a telescopic member 3 fixedly mounted on the fixed frame 21; and a counterweight 4 slidably mounted inside the hanging rod 22. The movement of the telescopic member 3 causes the counterweight 4 to move. When the hanging rod 22 becomes unbalanced while 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 4 to slide towards the unbalanced 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 component 3 deforms and displaces based on the force difference on both sides of the hanging rod 22, driving the counterweight 4 to slide towards the unbalanced side to restore balance. Through the linkage of the telescopic component 3 and the counterweight 4, an automatic balancing function is achieved, which is suitable for the stability requirements when moving heavy objects.

[0029] Example 2

[0030] Referring to Figure 2, this embodiment differs from the first embodiment in that the lower surface of the driven plate 32 forms a sealed connection with the upper end of the folded section 331 of the folded 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 folded tube 33 through sliding. The folded tube 33 compresses or releases the air in the storage chamber 333 through the deformation of the folded section 331 and the straight tube section 332, thereby achieving pressure transmission.

[0031] The driven plate 32 is slidably disposed inside the carrier 31, matching the inner diameter of the carrier 31 to ensure smooth movement without jamming, and can limit 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 folded section 331 of the folded 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 folded tube 33 by sliding. The folded tube 33 compresses or releases the air in the storage chamber 333 through the deformation of the folded section 331 and the straight tube section 332, thereby realizing the transmission of pressure.

[0032] The storage chamber 333 stores air and transmits pressure between the two carriers 31 through the connecting pipe 334. The connecting pipe 334 is set in the straight pipe section 332 of the two folded pipes 33 and connects the two storage chambers 333 to realize the flow of air.

[0033] Referring to Figure 4, the folded tube 33 has an elliptical ring structure. This structure offers high stability and strength, capable of withstanding significant pressure and deformation. While ensuring normal airflow within the tube, it provides a larger effective volume. The telescopic channel 34 is an axial channel inside the folded tube 33, used to house the spring 35 and the traction rope 36. Located at the center of the folded tube 33, the telescopic channel 34 is cylindrical, with a diameter smaller than the longitudinal diameter of the tube. In the extended or compressed state of the folded tube 33, the telescopic channel 34 ensures continued airflow within the tube, preventing airflow blockage due to deformation. The spring 35, located within the telescopic channel 34, provides elastic support for the driven plate 32, assisting in its reset. The spring 35 prevents the driven plate 32 from jamming or malfunctioning during movement. When the driven plate 32 slides downwards, the folded section 331 of the folded tube 33 is compressed, and the spring 35 is also compressed. Once the imbalance is resolved, the elastic restoring force of the spring 35 pushes the driven plate 32 back to its original position, restoring the folded tube 33 to its original shape.

[0034] The traction rope 36 is usually made of high-strength, wear-resistant materials, such as steel wire rope or synthetic fiber rope. The traction rope 36 passes through the bottom of the carrier 31, the fixing frame 21 and the hanging rod 22 in sequence. By setting the traction rope 36, the unbalanced state can be quickly detected and the motion 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] Referring to Figures 2-3, this embodiment differs from the first embodiment in that the guide groove 41 is located inside the hanging rod 22, providing a guiding path for the sliding of the counterweight 44. Limiting stops 42 are provided on both sides of the guide groove 41 to limit the range of motion of the pull rope 43. The pull rope 43 passes through the guide groove 41 and wraps around the limiting stops 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 imbalance, the pull rope 43 will respond immediately and pull the counterweight 44 to move towards the unbalanced side, increasing the weight on that side, thereby counteracting the imbalance. This can effectively cope with the imbalance problem caused by bumps or shaking during transportation.

[0037] Furthermore, during transportation, the hanging rod 22 plays a crucial role in connecting the motor to related components. Both ends of the hanging rod 22 are hooked onto two sets of lugs on the motor via hooks, thereby securing the motor and aiding in transportation. However, due to inevitable bumps and swaying during transportation, the instability of the motor can disrupt the force balance on both sides of the hanging rod 22.

[0038] When the left side of the hanging rod 22 loses weight, the balance of the entire system is broken instantly. The hanging rod 22 will tilt to the left and downward under the action of gravity. While the hanging rod 22 is tilting, it will exert a downward pull on the traction rope 36 on the left side. This pull is transmitted through the traction rope 36, causing the driven plate 32 connected to it 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 applies pressure to the folding section 331, causing the folding section 331 to begin folding. As the folding section 331 folds, the air originally stored in the left storage cavity 333 is compressed. Under the pressure, the air moves through the connecting pipe to the storage cavity 333 in the right folding tube 33;

[0040] When air rushes into the right storage chamber 333, the air pressure inside the right storage chamber 333 increases instantaneously. This increased air pressure creates an upward thrust, acting on the right driven plate 32. Under the action of this thrust, the right driven plate 32 causes the right folding section 331 to extend upward. At the same time, the upward movement of the right driven plate 32 also causes the right pull rope 43 to slide within the hanging rod 22. The pull rope 43 transmits the motion information from the right side to the counterweight 44, pulling the counterweight 44 to move. In the event of motor swaying causing one side of the hanging rod 22 to lose balance, the system can automatically adjust the counterweight distribution, restore balance, and ensure the stability and safety of the transportation process.

[0041] The rest of the structure is the same as in Example 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 intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
