Description
Technical Field
[0001] This utility model belongs to the field of embedded part hoisting technology, and specifically relates to a hoisting balance frame for embedded parts of substation equipment foundations. Background Technology
[0002] In the current field of substation equipment foundation embedded parts installation, the technological development of hoisting balance frames faces severe systemic challenges. The design concepts and technical architectures of traditional hoisting equipment are no longer sufficient to meet the stringent requirements of modern substation construction. Their technical limitations are mainly reflected in the following key aspects:
[0003] First, the size and weight of embedded parts pose significant operational difficulties for construction workers. Because embedded parts generally have large cross-sectional dimensions and significant self-weight, traditional manual handling and installation methods not only consume a lot of human resources but also severely prolong the construction period. More seriously, improper handling of heavy objects during handling and installation may lead to various safety accidents such as worker sprains and crush injuries. These potential personal safety hazards not only affect the construction progress but may also cause serious labor disputes and economic losses.
[0004] Secondly, the existing hoisting equipment has obvious shortcomings in its functional design. Its simplified structural design cannot meet the needs of precise construction. When the embedded parts are hoisted, the mobility of the equipment is severely limited, and it is impossible to make flexible spatial position adjustments. In particular, when it is necessary to adjust the angle of the embedded parts, it is necessary to rely on manual correction. This primitive adjustment method not only increases the labor intensity of construction workers, but also easily causes the positioning deviation of the embedded parts, which seriously affects the installation quality and efficiency.
[0005] More importantly, traditional hoisting equipment generally adopts a fixed structural design. Once the position of its core component—the winch—is determined, it is difficult to change. This rigid structural design severely restricts the adaptability and flexibility of the equipment. In actual construction, because the position of the winch or hook is fixed or the adjustment in the horizontal direction is extremely limited (such as the patent with authorization announcement number CN 215208160U that discloses a hoisting balance frame for embedded parts of substation equipment foundation), it is often impossible to make flexible adjustments for different installation environments and embedded part specifications. This technical limitation not only reduces construction efficiency but may also lead to the inability to complete the work smoothly in some installation positions, thereby affecting the overall project progress. Utility Model Content
[0006] The present invention aims to provide a hoisting balance frame for pre-embedded parts of substation equipment foundations to improve the flexibility of winch position adjustment.
[0007] This solution provides a substation equipment foundation embedded component hoisting balance frame, comprising a base, a movable frame rotatably connected to the base, a telescopic mechanism rotatably connected to the movable frame, and a connecting frame fixedly connected to the telescopic end of the telescopic mechanism; a hoisting frame rotatably connected to the top of the movable frame, one end of the hoisting frame rotatably connected to the connecting frame, and both the connecting frame and the movable frame having space for the hoisting frame to deflect; a sliding frame on the hoisting frame, a first motor mounted on the sliding frame, and a winch rotatably connected to the sliding frame, the winch being fixedly connected to the output shaft of the first motor; a lead screw rotatably connected to the hoisting frame, and a guide rod fixedly connected to the hoisting frame; a guide hole and a threaded hole on the sliding frame, the sliding frame being threadedly connected to the lead screw through the threaded hole, and slidingly connected to the guide rod through the guide hole; a second motor on the hoisting frame, the output shaft of the second motor being fixedly connected to the lead screw; and the rotatable connection between the hoisting frame and the movable frame located between the sliding frame and the connecting frame.
[0008] The working principle and beneficial effects of this scheme are as follows: When hoisting embedded parts for substation equipment foundations, the hoisting balance frame is first moved to a suitable position. The hoisting direction is initially adjusted by rotating the movable frame. Then, the telescopic mechanism is activated, its telescopic end pushing the connecting frame to move. The connecting frame then adjusts the angle of the connected hoisting frame to adapt to different hoisting position requirements. After the embedded part is hoisted, if the winch position needs adjustment, the second motor is started. The second motor drives the lead screw to rotate. Since the sliding frame is threadedly connected to the lead screw through a threaded hole and slidably connected to the guide rod through a guide hole, the rotation of the lead screw causes the sliding frame to move horizontally along the guide rod direction on the hoisting frame, thus achieving flexible adjustment of the winch position. During this process, the first motor drives the winch to rotate, completing the hoisting and lowering operations of the embedded part.
[0009] When hoisting embedded parts for substation equipment foundations, the base is first placed in a suitable position. The power unit drives the connecting shaft to rotate, which in turn rotates the movable frame around the base, achieving an initial adjustment of the hoisting direction. Subsequently, the telescopic mechanism is activated, its telescopic end pushing the connecting frame to move. The connecting frame then adjusts the angle of the connected hoisting frame to adapt to different hoisting positions. After the embedded part is hoisted, if the winch position needs adjustment, the second motor is started. The second motor drives the lead screw to rotate. Since the sliding frame is threadedly connected to the lead screw through a threaded hole and slidably connected to the guide rod through a guide hole, the rotation of the lead screw causes the sliding frame to move horizontally along the guide rod on the hoisting frame, thus achieving flexible adjustment of the winch position. During this process, the first motor drives the winch to rotate, completing the hoisting and lowering operations of the embedded part.
[0010] This solution, through the cooperation of lead screws, guide rods, and sliding frames, along with the drive of a second motor, can precisely and flexibly adjust the position of the winch on the hoisting frame, adapting to the needs of embedded parts of different specifications and complex installation environments. Compared with traditional fixed winches, it greatly improves the adaptability of the equipment. Furthermore, the movable frame can rotate around the base, and the telescopic mechanism and connecting frame can adjust the angle of the hoisting frame, making the entire hoisting balance frame more flexible in spatial positioning. This allows it to easily handle the hoisting of embedded parts in different directions and angles, reducing the need for manual adjustment and improving construction efficiency.
[0011] Furthermore, a fixed frame is fixedly connected to the bottom of the sliding frame, and the winch is rotatably connected to the fixed frame. The bottom of the fixed frame has a clearance groove located directly below the winch. The fixed frame, fixedly connected to the bottom of the sliding frame, is used to install the winch, making the winch installation more stable. During winch operation, the rope and / or hook can pass through the clearance groove, preventing the fixed frame from obstructing the movement of the rope or hook and ensuring smooth winch operation.
[0012] Furthermore, a sliding sleeve is fixedly connected inside the guide hole, and the sliding sleeve is slidably connected to the guide rod. The sliding sleeve can reduce the friction between the guide rod and the guide hole, extending the service life of the guide rod and the sliding frame; and the sliding sleeve can improve the stability of the sliding frame sliding on the guide rod, making the winch position adjustment more stable and precise.
[0013] Furthermore, a connecting shaft is rotatably connected to the base, and the movable frame is fixedly connected to the top of the connecting shaft. The connecting shaft is connected to a power component that drives its rotation.
[0014] Furthermore, the power assembly includes a third motor, the output shaft of which is connected to a drive gear, and the connecting shaft is coaxially connected to a driven gear, which meshes with the drive gear. The third motor provides power to the rotation of the connecting shaft through the meshing of the drive and driven gears, enabling precise rotation control of the movable frame, facilitating adjustment of the hoisting direction, and featuring a simple structure and high transmission efficiency.
[0015] Furthermore, the output shafts of the second and / or third motors are connected to reducers, and the output end of the reducers is connected to the corresponding lead screw or drive gear. The reducers lower the motor's output speed while increasing the output torque, resulting in smoother lead screw rotation and more powerful rotation of the movable frame. This improves the stability and reliability of the equipment operation, ensuring precise adjustment of the winch position and movable frame angle under different load conditions.
[0016] Furthermore, the telescopic mechanism is a hydraulic cylinder or a pneumatic cylinder. A rotating rod is fixedly connected to the end of the telescopic mechanism away from the connecting frame. The length direction of the rotating rod is perpendicular to the length direction of the telescopic mechanism. Two connecting seats are fixedly connected to the movable frame, and the two ends of the rotating rod are rotatably connected to the two connecting seats respectively. The use of a hydraulic cylinder or a pneumatic cylinder in the telescopic mechanism allows for more flexible angle adjustment of the connecting frame and the lifting frame during operation, adapting to different working scenarios. Simultaneously, the rotatable connection reduces stress concentration during operation, extending its service life. Preferably, a hydraulic cylinder is used for the telescopic mechanism. A hydraulic rod is fixedly connected to the output end of the hydraulic cylinder, and the connecting frame is fixedly connected to one end of the hydraulic cylinder.
[0017] Furthermore, the connecting frame is U-shaped, with the same rotating shaft rotatably connected to the opposite side walls of its open end. One end of the lifting frame has a connecting hole, the extension direction of which is perpendicular to the length direction of the lifting frame. The lifting frame is rotatably connected to the rotating shaft through the connecting hole. The U-shaped design of the connecting frame, with its rotating shaft rotatably connected to the opposite side walls of its open end, mates with the connecting hole at one end of the lifting frame, allowing the lifting frame to rotate around the rotating shaft. This provides a stable support structure for the deflection of the lifting frame. Simultaneously, the U-shaped design of the connecting frame provides sufficient space for the deflection of the lifting frame, ensuring that the lifting frame can be adjusted at a large angle.
[0018] Furthermore, the base is detachably connected to a mounting frame, which is located below the base and has casters at its bottom. The detachable mounting frame with casters at its bottom facilitates the movement and handling of the entire lifting and balancing frame.
[0019] Furthermore, the outer wall of the movable frame is provided with reinforcing plates. The reinforcing plates can enhance the structural strength of the movable frame and effectively prevent deformation when the movable frame rotates or is subjected to various forces during hoisting operations.

The fixed frame 4 is detachably mounted at the bottom of the lifting frame 5. The top of the connecting frame 7 is connected to one end of the lifting frame 5 via the rotating shaft 8. The lifting frame 5 is rotatably connected to the movable frame 6 via the rotating shaft 8. Specifically, the movable frame 6 is equipped with a mechanism for lifting the frame. The 5-axis deflects through a through slot near the top of the movable frame 6. The same rotating shaft 8 is fixedly connected to the opposite side walls of the through slot. The hoisting frame 5 consists of a horizontal bar and two vertical bars, forming an "F" shape. The hoisting frame 5 is rotatably connected to the rotating shaft 8 through a through hole. One end of the horizontal bar of the hoisting frame 5 is also provided with a through hole. The connecting frame 7 is "U" shaped. A rotating shaft 8 is also rotatably connected to the opposite side walls of the open end of the connecting frame 7. A connecting hole is provided on one of the vertical bars of the hoisting frame 5. The extension direction of the connecting hole is perpendicular to the length direction of the hoisting frame 5. The hoisting frame 5 is rotatably connected to the corresponding rotating shaft 8 through the connecting hole.
[0028] The movable frame 6 is positioned above the base 1. One end of the hydraulic cylinder 9 is rotatably connected to the movable frame 6. Specifically, a rotating rod is fixedly connected to the end of the hydraulic cylinder 9 furthest from the connecting frame 7. The length direction of the rotating rod is perpendicular to the length direction of the hydraulic cylinder 9. Two connecting seats are fixedly connected to the movable frame 6, and both ends of the rotating rod are rotatably connected to the two connecting seats respectively. The bottom end of the hydraulic rod 10 is connected to the output end of the hydraulic cylinder 9, and the top end of the hydraulic rod 10 is fixedly connected to the bottom end of the connecting frame 7.
[0029] An adjustment device is installed on the base 1. The adjustment device includes a connecting shaft 11, a driven bevel gear 12, and a driving bevel gear 13. The top end of the connecting shaft 11 is fixedly connected to the bottom end of the movable frame 6, and the movable frame 6 is rotatably connected to the base 1 through the connecting shaft 11. That is, the connecting shaft 11 is rotatably connected to the base 1. The driven bevel gear 12 is installed on the connecting shaft 11, and the driving bevel gear 13 is located on one side of the driven bevel gear 12. The driving bevel gear 13 and the driven bevel gear 12 mesh. A sliding device is provided on one side of the hoisting frame 5.
[0030] A mounting bracket 14 is detachably provided below the base 1, and a caster wheel 15 is movably provided below the mounting bracket 14.
[0031] A reinforcing plate 16 is fixedly installed on the outside of the movable frame 6.
[0032] The bottom of the fixed frame 4 is provided with a clearance groove 17, which is located directly below the winch 3.
[0033] A third motor 18 is detachably mounted on the base 1, and the output shaft of the third motor 18 is connected to the drive bevel gear 13.
[0034] In this embodiment, when the device is needed, it is first moved by the external drive device. Then, the device moves via the casters 15 installed below the base 1. Once the device is in the appropriate position, the external drive device is turned off, and then the first motor 2 on one side of the fixed frame 4 is turned on. The first motor 2 drives the winch 3 to rotate forward, thereby lowering the steel cable and lifting hook on the outside of the winch 3. The embedded part is then fixed by the steel cable and lifting hook on the outside of the winch 3. Then, the first motor 2 drives the winch 3 to rotate in reverse, thereby lifting the embedded part by the steel cable and lifting hook. Then, the hydraulic cylinder 9 is turned on, and the hydraulic cylinder 9 drives the connecting frame 7 to move via the hydraulic rod 10 connected to the output end. Since the connecting frame 7 is rotatably connected to the lifting frame 5 via the rotating shaft 8, and the connecting frame 7 moves by its opposite... The corresponding rotating shaft 8 is rotatably connected to the movable frame 6. Then, one end of the hoisting frame 5 will be driven to descend through the connecting frame 7, thereby causing the other end of the hoisting frame 5 to drive the sliding frame 19 and the winch 3 to rise. This allows the winch 3 to lift the embedded part again through the external steel cable and lifting hook. The reinforcement plate 16 strengthens the structural strength of the movable frame 6 and ensures hoisting stability. When it is necessary to adjust the equipment angle, the third motor 18 installed on the base 1 is turned on. The third motor 18 drives the active bevel gear 13 to rotate. Then, the active bevel gear 13 drives the driven bevel gear 12 meshing with it on one side to rotate. Then, the driven bevel gear 12 drives the connecting shaft 11 to rotate. Then, the connecting shaft 11 drives the movable frame 6 to rotate, thereby changing the angle of the hoisting frame 5 and the hoisted embedded part. After the adjustment is appropriate, the third motor 18 is turned off.
[0035] Figures 1-5 As shown, one embodiment of the sliding device is as follows: the sliding device includes a sliding frame 19, a threaded hole 20, a second motor 21, and a lead screw 22. The sliding frame 19 is slidably mounted on one side of the lifting frame 5. The second motor 21 is detachably mounted on the side of the lifting frame 5 away from the connecting frame 7. The lead screw 22 is rotatably mounted between the two vertical rods of the lifting frame 5. A guide rod is also fixedly mounted between the two vertical rods of the lifting frame 5, and the guide rod is located directly below the lead screw 22. The sliding frame 19 has a threaded hole 20 and a guide hole along its length. The sliding frame 19 is threadedly connected to the lead screw 22 through the threaded hole 20. A sliding sleeve 23 is fixedly mounted in the guide hole, and the sliding sleeve 23 is slidably connected to the guide rod.
[0036] A reducer 24 is detachably installed on one side of the hoisting frame 5 and on the base 1. The input end of the reducer 24 on the hoisting frame 5 is connected to the output end of the second motor 21, and the output end of the reducer 24 on the hoisting frame 5 is connected to one end of the lead screw 22. A reducer 24 is also installed on the base 1. The input end of the reducer 24 is connected to the output end of the third motor 18, and the output end of the reducer 24 on the base 1 is connected to the drive bevel gear 13.
[0037] More specifically, when it is necessary to move the position of the winch 3, first turn on the second motor 21. After the output end of the second motor 21 is reduced by the reducer 24 connected to the output end, it drives the lead screw 22 to rotate. Then, the sliding frame 19 will drive the sliding sleeve 23 to slide along the hoisting frame 5 through the cooperation with the lead screw 22, so that the sliding frame 19 drives the winch 3 to move. When the winch 3 moves to the appropriate position, the second motor 21 can be turned off.
[0038] In summary, during the use or operation of the overall equipment: When the equipment needs to be used, it is first moved by the external drive device. Then, the equipment moves via the casters 15 installed under the base 1. After the equipment moves to the appropriate position, the external drive device is turned off, and then the first motor 2 installed on one side of the fixed frame 4 is turned on. The first motor 2 drives the winch 3 to rotate, thereby lowering the steel cable and lifting hook on the outside of the winch 3. Then, the embedded part is fixed by the steel cable and lifting hook on the outside of the winch 3. Then, the first motor 2 drives the winch 3 to reverse, thereby lifting the embedded part by the steel cable and lifting hook. Then, the hydraulic cylinder 9 is turned on. The hydraulic cylinder 9 drives the connecting frame 7 to move through the hydraulic rod 10 connected to the output end. Since the connecting frame 7 is rotatably connected to the lifting frame 5 through the rotating shaft 8, and the connecting frame 7 is connected to the movable frame 6 through the corresponding rotating shaft 8... The connection is rotated, and then one end of the hoisting frame 5 will be lowered through the connecting frame 7, thereby causing the other end of the hoisting frame 5 to lift the sliding frame 19 and the winch 3. This allows the winch 3 to lift the embedded part again through the external steel cable and lifting hook. The reinforcement plate 16 strengthens the structural strength of the movable frame 6 and ensures the hoisting stability. When it is necessary to adjust the equipment angle, the third motor 18 installed on the base 1 is turned on. After the third motor 18 is decelerated by the reducer 24 connected to the output end, it drives the active bevel gear 13 connected to the output end of the reducer 24 to rotate. Then the active bevel gear 13 drives the driven bevel gear 12 meshing with it on one side to rotate. Then the driven bevel gear 12 drives the connecting shaft 11 to rotate. Then the connecting shaft 11 drives the movable frame 6 to rotate, thereby changing the angle of the hoisting frame 5 and the hoisted embedded part. After the adjustment is appropriate, the third motor 18 can be turned off.
[0039] When it is necessary to move the position of the winch 3, first turn on the second motor 21. After the output end of the second motor 21 is reduced by the reducer 24 connected to the output end, it drives the lead screw 22 to rotate. Then, the sliding frame 19 will drive the sliding sleeve 23 to slide along the hoisting frame 5 through the cooperation with the lead screw 22, so that the sliding frame 19 drives the winch 3 to move. When the winch 3 is moved to the appropriate position, turn off the second motor 21.
