Description

Technical Field

[0001] This utility model relates to the field of power equipment hoisting technology, and in particular to a power equipment hoisting balancing device. Background Technology

[0002] During the installation and maintenance of power systems, power equipment such as transformers, switchgear, and distribution boxes often require high-altitude or long-distance hoisting operations. These devices are typically complex in structure, heavy in weight, and vary in size. During hoisting, they are prone to tilting, swaying, or even slipping due to shifts in the center of gravity or uneven stress, posing significant safety risks.

[0003] Traditional hoisting methods often involve directly binding the equipment with wire ropes or slings, relying on manual adjustment of balance. This is cumbersome, and when the weight distribution is uneven, conventional hoisting devices cannot dynamically adjust their own balance, resulting in uneven stress on the main beam and potentially causing structural deformation.

[0004] Therefore, a power equipment hoisting balancing device is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a power equipment hoisting balancing device to solve the above problems. It improves upon the traditional hoisting method, which often uses wire ropes or slings to directly bind the equipment and relies on manual adjustment of balance. This method is cumbersome and, when the hoisting weight is unevenly distributed, conventional hoisting devices cannot dynamically adjust their own balance, resulting in uneven stress on the main beam and potentially causing structural deformation.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a power equipment hoisting balancing device, comprising: Main lifting beam; A lifting platform, which is located below the main lifting beam; Multiple lifting lugs are fixedly connected to the lower end of the main lifting beam and the upper end of the lifting platform, respectively. Multiple steel wire ropes, each with a lifting ring fixedly connected to both ends, and a lifting ring fitted inside each lifting lug; The clamping mechanism includes a motor, a bidirectional threaded rod, a limiting rod, a slider, a sliding groove, and a C-shaped clamping plate. Two sliders, sliding grooves, and C-shaped clamping plates are provided. The motor is fixedly connected to one side of the lifting platform by bolts. The bidirectional threaded rod is fixedly connected to the output shaft of the motor and rotatably connected inside the lifting platform. The limiting rod is fixedly connected to the adjacent ends of the inner walls on both sides of the lifting platform. The two sliders are slidably connected to the circumferential surface of the bidirectional threaded rod and the circumferential surface of the limiting rod, respectively. Two sliding grooves are respectively opened at the upper end of the lifting platform, and the two sliders are slidably connected within the two sliding grooves. The two C-shaped clamping plates are fixedly connected to one side of the two sliders. The counterweight assembly consists of four sets, each set of which is installed at the upper end of the lifting platform to adjust the balance of the platform when lifting electrical equipment with uneven weight.

[0007] Preferably, each set of counterweight components includes a T-slot, a T-block, a counterweight block, a threaded hole, and a screw. The T-slot is located on one side of the platform, the T-block is inserted into the T-slot, the counterweight block is fixedly connected to the upper end of the T-block, the lower inner wall of the T-slot has a threaded hole, and the screw passes through the through holes on the T-block and the counterweight block and is threaded into the threaded hole.

[0008] Preferably, a plurality of telescopic rods are fixedly connected to the lower end of the platform, a spring is fixedly connected to the circumferential surface of each telescopic rod, and a washer is fixedly connected to the lower end of each telescopic rod.

[0009] Preferably, the upper end of the lifting platform has two guide grooves, and multiple guide blocks are slidably connected in the two guide grooves. The lower end of each C-shaped clamp is fixedly connected to two guide blocks.

[0010] Preferably, a support block is fixedly connected to one side of the lifting platform, and a motor is attached to the upper end of the support block.

[0011] Preferably, an anti-slip pad is fixedly connected to one side of each of the C-shaped clamps.

[0012] Preferably, four anti-collision blocks are fixedly connected to the four corners of the platform, and the anti-collision blocks are made of rubber.

[0013] The beneficial effects of this utility model are: This device utilizes an automatic clamping mechanism consisting of a motor, a bidirectional threaded rod, a slider, and C-shaped clamps. By starting the motor, the two C-shaped clamps move synchronously towards each other, quickly and securely clamping the electrical equipment placed on the hoisting platform from both sides. Anti-slip pads further increase friction, effectively preventing lateral displacement or slippage of the equipment during hoisting. This automated clamping method not only reduces the labor intensity of workers and simplifies the operation process, but also provides uniform and reliable clamping force, greatly reducing the safety risks caused by equipment loosening and ensuring a smooth hoisting process.

[0014] This device, by installing detachable counterweight components on the lifting platform, allows personnel to flexibly add, remove, or adjust the counterweights on different sides of the platform based on the actual center of gravity position of the lifting equipment. When the electrical equipment is placed on the platform surface, personnel can observe the tilt angle of the platform and adjust the counterweights accordingly. This design enables the entire lifting system to adjust its center of gravity in real time according to the load conditions, ensuring that the platform remains horizontal and stable during the lifting process. It avoids tilting, swaying, or even slippage accidents caused by eccentric loads, significantly improving the safety and reliability of high-altitude lifting operations. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1:

[0018] Please see Figures 1-4 The present invention provides the following technical solution: A power equipment hoisting balancing device, comprising: Main lifting beam 1; Lifting platform 2 is located below the main lifting beam 1; Multiple lifting lugs 3 are fixedly connected to the lower end of the main lifting beam 1 and the upper end of the lifting platform 2, respectively. Multiple steel wire ropes 4, with lifting rings fixedly connected to both ends of the multiple steel wire ropes 4, and a lifting ring fitted inside each lifting lug 3; The clamping mechanism includes a motor 5, a bidirectional threaded rod 6, a limiting rod 7, a slider 8, a sliding groove 9, and a C-shaped clamping plate 10. There are two sliders 8, two sliding grooves 9, and two C-shaped clamping plates 10. The motor 5 is fixedly connected to one side of the lifting platform 2 by bolts. The bidirectional threaded rod 6 is fixedly connected to the output shaft of the motor 5 and rotatably connected inside the lifting platform 2. The limiting rod 7 is fixedly connected to the inner walls of both sides of the lifting platform 2 at close proximity. The two sliders 8 are slidably connected to the circumferential surface of the bidirectional threaded rod 6 and the circumferential surface of the limiting rod 7, respectively. The two sliding grooves 9 are respectively opened at the upper end of the lifting platform 2, and the two sliders 8 are slidably connected inside the two sliding grooves 9, respectively. The two C-shaped clamping plates 10 are fixedly connected to one side of the two sliders 8, respectively. The counterweight assembly consists of four sets, each set of which is installed at the top of the lifting platform 2 to adjust the balance of the lifting platform 2 when lifting electrical equipment with uneven weight.

[0019] In a specific embodiment of this utility model, when the main lifting beam 1 is hoisted by external lifting equipment, the electrical equipment is placed on the upper end of the lifting platform 2. The lifting platform 2 is connected to the main lifting beam 1 by multiple wire ropes 4. The lifting rings at both ends of the wire ropes 4 are respectively fitted onto the lifting lugs 3 at the lower end of the main lifting beam 1 and the upper end of the lifting platform 2, forming a stable suspension structure. When the electrical equipment is placed on the lifting platform 2, the operator starts the motor 5. The motor 5 drives the bidirectional threaded rod 6 to rotate. The two sliders 8 have sliding nuts inside. Since the sliding nuts inside the two sliders 8 respectively engage with the two sections of the bidirectional threaded rod 6 and are subject to the limiting rod 7... Guided constraint, the slider 8 slides towards or away from each other along the direction of the limiting rod 7 inside the lifting platform 2. As the slider 8 moves, it slides synchronously on the upper end of the lifting platform 2 through the sliding groove 9, driving the C-shaped clamp 10 to move in the horizontal direction. When the C-shaped clamp 10 moves inward to both sides of the power equipment, it clamps the outer wall of the equipment body. The two C-shaped clamps 10 apply clamping force to the power equipment from the left and right directions to prevent it from lateral displacement during the hoisting process. When the hoisting operation is carried out, even if it is affected by wind or swaying, the clamping mechanism can still effectively limit the shaking of the power equipment, prevent it from slipping or falling, and ensure the safety and reliability of the hoisting process.

[0020] Please refer to the details. Figures 1-4Each counterweight assembly includes a T-slot 11, a T-block 12, a counterweight 13, a threaded hole 14, and a screw 15. The T-slot 11 is located on one side of the lifting platform 2. The T-block 12 is inserted into the T-slot 11. The counterweight 13 is fixedly connected to the upper end of the T-block 12. The lower inner wall of the T-slot 11 has a threaded hole 14. The screw 15 passes through the through holes on the T-block 12 and the counterweight 13 and is threaded into the threaded hole 14.

[0021] In this embodiment: when it is necessary to adjust the balance of the lifting platform 2, the operator inserts the counterweight block 13 with the T-shaped insert 12 into the T-shaped slot 11 opened on the lifting platform 2 from the side. After the T-shaped insert 12 slides into the T-shaped slot 11, its bottom through hole is aligned with the threaded hole 14 on the lower inner wall of the T-shaped slot 11. When the screw 15 passes through the through holes on the T-shaped insert 12 and the counterweight block 13 and is screwed into the threaded hole 14, the counterweight block 13 is fixed on the lifting platform 2. In this way, by adding, removing or moving the counterweight components in different positions, the center of gravity of the lifting system can be adjusted.

[0022] Please refer to the details. Figures 1-4 Multiple telescopic rods 16 are fixedly connected to the lower end of the suspended platform 2. A spring 17 is fixedly connected to the circumferential surface of each telescopic rod 16, and a washer 18 is fixedly connected to the lower end of each telescopic rod 16.

[0023] In this embodiment: when the platform 2 carrying the power equipment is hoisted to the target position by the lifting equipment and begins to slowly descend and contact the ground, the multiple telescopic rods 16 connected to the lower end of the platform 2 first bear the pressure from the upper structure. The springs 17 sleeved on the telescopic rods 16 undergo elastic deformation due to the pressure, gradually absorbing the impact energy generated at the moment the platform 2 contacts the ground. When the platform 2 is fully lowered, the pads 18 at the lower end of the telescopic rods 16 evenly transmit the load and disperse the bottom stress. Through the buffering effect of the springs 17, the impact on the motor 5, double-threaded rod 6 and other components installed inside the platform 2 is reduced, and internal components are prevented from loosening or being damaged due to severe vibration.

[0024] Please refer to the details. Figures 1-4 Two guide grooves 19 are respectively opened at the upper end of the hanging platform 2. Multiple guide blocks 20 are slidably connected in the two guide grooves 19. Two guide blocks 20 are fixedly connected to the lower end of each C-shaped clamp 10.

[0025] In this embodiment: when the C-shaped clamp 10 moves horizontally under the drive of the motor 5, the two guide blocks 20 fixed at its lower end slide synchronously in the guide groove 19 opened at the upper end of the lifting platform 2. The movement of the guide blocks 20 in the guide groove 19 restricts the deflection of the C-shaped clamp 10, so that it can only move smoothly along the predetermined trajectory. When the two C-shaped clamps 10 on both sides move at the same time, the guide structure ensures the consistency and reliability of the clamping action.

[0026] Please refer to the details. Figures 1-4 A support block 21 is fixedly connected to one side of the hanging platform 2, and a motor 5 is attached to the upper end of the support block 21.

[0027] In this embodiment: when the motor 5 is installed on the side of the platform 2, its main body is attached to the upper surface of the support block 21. The support block 21 provides additional support for the motor 5 and shares the stress at the bolt connection. When the motor 5 runs and outputs torque, the support block 21 effectively prevents the motor 5 from loosening or tilting due to vibration, and maintains the coordinated operation of the drive system.

[0028] Please refer to the details. Figures 1-4 Each C-shaped clamp 10 has an anti-slip pad 22 fixedly connected to one side end.

[0029] In this embodiment: when the C-shaped clamp 10 moves inward and clamps the power equipment placed above the hoisting platform 2, the anti-slip pad 22 provided on one side of it contacts the outer surface of the power equipment. The anti-slip pad 22 generates a large frictional resistance under the action of clamping force, which effectively prevents the power equipment from sliding or displacing laterally during hoisting.

[0030] Please refer to the details. Figures 1-4 Four anti-collision blocks 23 are fixedly connected to the four corners of the hanging platform 2. The anti-collision blocks 23 are made of rubber.

[0031] In this embodiment: when the platform 2 moves in a narrow space or approaches other structures, the rubber anti-collision blocks 23 set at its four corners first come into contact with the surrounding objects. The anti-collision blocks 23 absorb the collision energy by their own elastic deformation, preventing the platform 2 body from being subjected to hard impact. When the device frequently performs hoisting operations, the anti-collision blocks 23 continue to play a protective role, extending the service life of the overall structure.

[0032] Workflow: When starting the hoisting operation of the power equipment, first place the power equipment to be hoisted above the hoisting platform 2, positioning it in the central area of ​​the platform 2. At this time, the external lifting equipment is connected to the main lifting beam 1 via steel wire ropes 4. The main lifting beam 1 suspends the hoisting platform 2 via multiple steel wire ropes 4. The lifting rings at both ends of the steel wire ropes 4 are respectively fitted onto the lifting lugs 3 on the main lifting beam 1 and the hoisting platform 2, forming a stable multi-point suspension structure. After the power equipment is in place, the operator starts the motor 5, which drives the bidirectional threaded rod 6 on its output shaft to rotate. Since the two sliders 8 respectively engage with the left and right threaded sections of the bidirectional threaded rod 6 and are subject to the limiting rod 7, the operation is carried out smoothly. Guided by the constraints, the sliders 8 move synchronously towards each other in the horizontal direction inside the lifting platform 2. The movement of the sliders 8 is transmitted to the C-shaped clamps 10 through the slide grooves 9, causing the two C-shaped clamps 10 to move from both sides towards the center. When the C-shaped clamps 10 move to the outside of the power equipment, the anti-slip pads 22 on their inner sides contact the surface of the equipment and apply clamping force, firmly fixing the power equipment above the lifting platform 2 and preventing it from sliding or shifting during the hoisting process. At the same time, the guide blocks 20 at the lower end of the C-shaped clamps 10 slide in the guide grooves 19 on the lifting platform 2 to ensure that the clamping action is smooth and without deflection. After the equipment is clamped, the external lifting equipment begins to lift the main lifting beam 1. The lifting platform 2 rises together with the main lifting beam 1. During the lifting process, if the weight distribution of the electrical equipment is uneven, the operator can select to activate counterweight components at different positions according to the actual situation: insert the counterweight block 13 with T-shaped insert 12 into the T-shaped slot 11 on the side of the lifting platform 2, and screw it into the threaded hole 14 with screw 15 to lock it, thereby adjusting the overall center of gravity of the lifting platform 2 and achieving lifting balance. During the entire lifting process, the rubber anti-collision blocks 23 at the four corners of the lifting platform 2 can provide flexible contact when approaching obstacles to avoid hard collisions; the support block 21 continuously provides support for the motor 5 to ensure the stable operation of the drive system. When the lifting platform 2 carries electrical equipment... After the hoisting equipment lifts the platform 2 to the target position, it begins to slowly descend and touch the ground. The multiple telescopic rods 16 connected to the lower end of the platform 2 first bear the pressure from the structure above. The springs 17 sleeved on the telescopic rods 16 undergo elastic deformation due to the pressure, gradually absorbing the impact energy generated when the platform 2 contacts the ground. When the platform 2 is fully in place, the pads 18 at the lower end of the telescopic rods 16 evenly transfer the load and disperse the bottom stress. Through the buffering effect of the springs 17, the impact damage to the internal components of the platform 2 is reduced. After the hoisting operation is completed, the motor 5 starts in reverse, the C-shaped clamp 10 releases the power equipment, and the entire process is completed.

[0033] It should be noted that the connection and use of motor 5 in this solution are existing technologies, and will not be elaborated on further in this article.

The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through the control unit.
