Description

Technical Field

[0001] This utility model belongs to the field of infrastructure substation construction technology, and specifically relates to a lifting device for infrastructure substation construction. Background Technology

[0002] Substations play a crucial role in modern power systems, serving not only as key nodes in power transmission and distribution but also as vital links in ensuring stable power supply and improving energy efficiency. Their importance is further highlighted by the increasing demand for electricity and the improvement of power grid construction.

[0003] Substations are densely packed with various electrical equipment. During substation construction, long-arm cranes are typically used to suspend large pieces of equipment. When suspending equipment, long-arm cranes usually use steel cables with hooks attached to them, and then use the hooks to connect to the supports or ropes binding the equipment for lifting. However, this lifting method is relatively simple. While it is acceptable for lifting some block-shaped or vertical equipment due to the dense arrangement of equipment in substations, it is not convenient to control the rotation and alignment of long, horizontal structures, such as tubular busbars, when lifting them. This makes the process particularly time-consuming and troublesome during construction. Utility Model Content

[0004] In order to solve the above-mentioned problems in the existing technology, this utility model provides a lifting device for infrastructure substation construction, which can facilitate the control of the rotation and alignment of tubular busbars, and is relatively simple to assemble.

[0005] The technical solution of this utility model is as follows:

[0006] To address the above problems, the purpose of this utility model is to provide a lifting device for substation construction, which solves the problem of lifting by connecting hooks to steel cables and then connecting the hooks to the supports or ropes binding the equipment. This lifting method is relatively simple and is suitable for lifting some block or vertical equipment in substations where equipment is relatively dense. However, when lifting long horizontal structures, such as tubular busbars, it is not convenient to control the rotation and alignment of the tubular busbars, which is particularly time-consuming and troublesome during construction.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a lifting device for infrastructure and substation construction, comprising a plate, a hanging block fixedly disposed at the upper center of the plate, an annular groove formed on the side of the plate, a rotating ring rotatably disposed on the inner side of the annular groove, inclined lifting rods symmetrically fixedly disposed on the lower sides of the rotating ring, a horizontal lifting rod fixedly disposed at the lower end of the inclined lifting rods, fixed plates symmetrically fixedly disposed on the lower side of the plate, a motor fixedly disposed between the fixed plates, a connecting plate fixedly disposed with the output end of the motor facing downward, connecting rods symmetrically disposed on both sides of the connecting plate, the connecting rods being fixedly connected to the inclined lifting rods, lifting blocks symmetrically disposed on the lower side of the horizontal lifting rods, and lifting holes being formed through the sides of each lifting block.

[0008] The beneficial effects of this utility model are as follows: the steel cable connecting hook of the crane hooks onto the hanging block, and the lower side of the horizontal lifting rod is connected to the ropes binding both sides of the tubular busbar through the lifting hole of the lifting block. After the tubular busbar is suspended to the installation position by the crane, the motor is started. The output end of the motor drives the connecting plate to rotate. The connecting plate drives the inclined lifting rod to rotate through the connecting rod. The inclined lifting rod drives the horizontal lifting rod to rotate. The horizontal lifting rod can drive the tubular busbar under the lifting hole to rotate, thereby rotating the tubular busbar, adjusting the orientation and alignment of the tubular busbar and other structures, and increasing the construction efficiency of the tubular busbar and other structures.

[0009] To increase the structural strength of the diagonal hanger;

[0010] As a further improvement to the above technical solution: the connecting rod is inclined upward towards the side closer to the inclined suspension rod.

[0011] The beneficial effects of this improvement are: the connecting rod can provide some upward support to the inclined hanger, increasing the structural strength of the inclined hanger.

[0012] For use in adjusting the position of the sliding adjustment block;

[0013] As a further improvement to the above technical solution: slots are provided on both sides of the horizontal suspension rod, and the suspension block is slidably engaged with the horizontal suspension rod through the slots.

[0014] The beneficial effect of this improvement is that it allows for the sliding adjustment of the position of the lifting block.

[0015] In order to adjust the position of the lifting block while maintaining its stability;

[0016] As a further improvement to the above technical solution: a fixing block is fixedly installed at the lower center of the horizontal lifting rod, and side blocks are symmetrically fixedly installed on both sides of the lower side of the horizontal lifting rod. A threaded rod is rotatably installed between the side block and the fixing block. A handle is fixedly installed through the side block at the end of the threaded rod away from the fixing block, and the threaded rod is threadedly connected to the lifting block.

[0017] The beneficial effects of this improvement are: by rotating the threaded rod through the handle, the threaded rod and the lifting block are driven by the thread, which is used to adjust the position of the lifting block while maintaining the stability of the lifting block.

[0018] In order to control the lifting blocks to move away and approach synchronously;

[0019] As a further improvement to the above technical solution: the threaded rod is rotatably inserted into the fixed block, the ends of the threaded rod that are close to each other are fixedly connected, and the threaded connections of the two lifting blocks and the threaded rod are in opposite directions.

[0020] The beneficial effects of this improvement are: the threaded rods are connected as a single threaded rod, and the rotation of the entire threaded rod can be controlled by a handle on one side, thereby controlling the lifting blocks to move away and closer synchronously.

[0021] For use in disassembling and replacing the crossbar;

[0022] As a further improvement to the above technical solution: a connecting groove is provided on the upper side of the lower end of the inclined suspension rod, and bolts are threaded on the inner side of the connecting groove. The bolts all pass through the inclined suspension rod and are threadedly connected to the horizontal suspension rod.

[0023] The beneficial effect of this improvement is that it is used for disassembling and replacing horizontal hangers.

[0024] The parts of the device not covered herein are the same as or can be implemented using existing technologies.

[0025] This utility model has the following beneficial effects:

[0026] This invention achieves dynamic adjustment of the suspension posture of the tubular busbar through the coordinated operation of the disk block, rotating ring, motor drive mechanism, and hoisting components: the hanging block on the disk block is connected to the crane cable to form the main load-bearing point; the rotating ring forms a rotating pair with the disk block through the ring groove; the motor drives the connecting rod through the connecting plate to drive the inclined hoisting rod to rotate as a whole, so that the horizontal hoisting rod and the tubular busbar it is hoisted can be steered and aligned; in conjunction with the centrifugal mechanical damping mechanism built into the rotating ring, the centrifugal counterweight block links the piston to compress the magnetorheological fluid to form variable damping during rotation, effectively suppressing hoisting sway; at the same time, the horizontal hoisting rod adopts a telescopic sleeve structure with adjustable hoisting blocks, and the hoisting point spacing is adjusted bidirectionally through the threaded rod, achieving the technical effect of accurately adapting to different specifications of tubular busbars and improving hoisting stability and construction efficiency in multiple dimensions.

[0034] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0035] like Figure 1 — Figure 5As shown: A lifting device for infrastructure substation construction includes a panel 1. A hanging block 2 is fixedly installed at the upper center of the panel 1. An annular groove 3 is formed on the side of the panel 1. A rotating ring 4 is rotatably installed inside the annular groove. Inclined lifting rods 5 are symmetrically fixedly installed on the lower sides of the rotating ring 4. A horizontal lifting rod 10 is fixedly installed at the lower end of the inclined lifting rod 5. Fixed plates 6 are symmetrically fixedly installed on the lower side of the panel 1. A motor 7 is fixedly installed between the fixed plates 6. A connecting plate 8 is fixedly installed with the output end of the motor 7 facing downward. Connecting rods 9 are symmetrically installed on both sides of the connecting plate 8. The connecting rods 9 are fixedly connected to the inclined lifting rods 5. Lifting blocks 11 are symmetrically installed on the lower side of the horizontal lifting rod 10. The sides of the lifting blocks 11 are all through-holes. A lifting hole 12 is provided. The crane's steel cable connecting hook hooks onto the hanging block 2. The lower side of the horizontal lifting rod 10 is connected to the ropes binding both sides of the tubular busbar through the lifting hole 12 of the lifting block 11. After the tubular busbar is suspended to the installation position by the crane, the motor 7 is started. The motor 7 is powered by the crane's power supply through a long cable. The control switch of the motor 7 is connected to the interface between the long cable and the power supply. The output end of the motor 7 drives the connecting plate 8 to rotate. The connecting plate 8 drives the inclined lifting rod 5 to rotate through the connecting rod 9. The inclined lifting rod 5 drives the horizontal lifting rod 10 to rotate. The horizontal lifting rod 10 can drive the tubular busbar under the lifting hole 12 to rotate, thereby rotating the tubular busbar, adjusting the orientation and alignment of the tubular busbar and other structures, and increasing the construction efficiency of the tubular busbar and other structures. The connecting rod 9 is inclined upward towards the side closer to the inclined suspension rod 5, providing upward support to the inclined suspension rod 5 and increasing its structural strength. The horizontal suspension rod 10 has slots 13 on both sides, through which the suspension block 11 slides and engages with the horizontal suspension rod 10, allowing for sliding adjustment of its position. A fixing block 15 is fixedly installed at the lower center of the horizontal suspension rod 10, and side blocks 14 are symmetrically fixed on both sides of its lower side. A threaded rod 16 is rotatably installed between the side blocks 14 and the fixing blocks 15. A handle 17 is fixedly installed at the end of the threaded rod 16 away from the fixing block 15, passing through the side block 14. The threaded rod 16 is threadedly connected to the suspension block 11, and the handle 17... The threaded rod 16 is driven to rotate, and the threaded rod 16 is threaded to the lifting block 11. This is used to adjust the position of the lifting block 11 while maintaining its stability. The threaded rod 16 is rotatably inserted into the fixed block 15. The ends of the threaded rod 16 that are close to each other are fixedly connected. The threaded connection directions of the two lifting blocks 11 and the threaded rod 16 are opposite. The threaded rod 16 is connected as a whole. The threaded rod 16 can be rotated as a whole by using the handle 17 on one side, thereby controlling the lifting blocks 11 to move away and closer synchronously. A connecting groove 18 is opened on the upper side of the lower end of the inclined lifting rod 5. Bolts 19 are threaded on the inner side of the connecting groove 18. The bolts 19 all pass through the inclined lifting rod 5 and are threaded to the horizontal lifting rod 10 for disassembly and replacement of the horizontal lifting rod 10.

[0036] As a preferred embodiment, the rotating ring 4 integrates a centrifugal mechanical damping mechanism, which includes six radial damping cavities 20 evenly distributed around the circumference of the rotating ring 4. Each radial damping cavity 20 contains a radially sliding piston block 21, and a guide rod 22 extends from the outer end of the piston block 21. The center of the guide rod 22 is rotatably mounted in the radial damping cavity 20, and the outer end of the guide rod 22 is connected to a centrifugal counterweight block 24 through a ball joint 23. Adjacent radial damping cavities 20 are connected in series through oil passages 26. A spring 25 is provided at the inner end of the piston block 21, and the inner end of the spring 25 is sealed by a sealing membrane in the radial damping cavity 20. The oil passages 26 are filled with magnetorheological fluid 27, and an electromagnetic regulating valve is embedded in the middle of the oil passages 26.

[0037] When the rotational speed of the rotating ring 4 increases, the centrifugal counterweight 24 swings outward under centrifugal force, pushing the piston block 21 to move through the rotation of the ball joint 23 and the guide rod 22. This compresses the inner spring 25 and changes the volume of the radial damping cavity 20 through the sealing membrane, forcing the magnetorheological fluid 27 in the cavity to flow through the oil passage 26. At this time, the electromagnetic regulating valve applies a controllable magnetic field according to the speed change, causing the viscosity of the magnetorheological fluid 27 flowing through the valve body to increase dramatically under the action of the magnetic field, forming a flow resistance positively correlated with the speed. This resistance is transmitted to each radial damping cavity 20 through the series oil passage 26, generating a differential pressure damping force on both sides of the piston block 21 to suppress rotation. At the same time, the compressed spring 25 provides a displacement reset function, ultimately achieving the dual effect of dynamic vibration suppression and emergency braking of the rotating ring, significantly improving the stability and positioning accuracy of the tubular busbar hoisting process.

[0038] The horizontal suspension rod 10 consists of an inner sleeve and an outer sleeve forming a telescopic structure. The inner sleeve has equally spaced positioning holes on its surface, and the outer sleeve has an elastic positioning pin with a handle at its end. The elastic positioning pin can be inserted into the positioning holes at different positions to achieve length locking.

[0039] The working principle of the aforementioned lifting device for infrastructure and substation construction is as follows:

[0040] In use, the crane's cable hooks engage with the hanging block 2. The lower side of the horizontal lifting rod 10 connects to the ropes binding both sides of the tubular busbar via the lifting hole 12 of the lifting block 11. After the tubular busbar is suspended to the installation position by the crane, the motor 7 is started. The motor 7 is powered by a long cable connected to the crane's power supply. The control switch for the motor 7 is also connected to the power supply interface. The output of the motor 7 drives the connecting plate 8 to rotate. The connecting plate 8, through the connecting rod 9, drives the inclined lifting rod 5 to rotate. The inclined lifting rod 5 drives the horizontal lifting rod 10 to rotate. The horizontal lifting rod 10 can then drive the tubular busbar below the lifting hole 12 to rotate, thereby rotating the tubular busbar and adjusting the orientation and alignment of the tubular busbar and other structures, increasing the efficiency of the construction of the tubular busbar and other structures. Furthermore, the connecting rod 9 is angled upwards towards the side closer to the inclined lifting rod 5, providing upward support to the inclined lifting rod 5 and increasing its structural strength. Both sides of the horizontal suspension rod 10 are provided with slots 13, and the suspension blocks 11 are slidably engaged with the horizontal suspension rod 10 through the slots 13 for adjusting the position of the suspension blocks 11. In addition, the threaded rod 16 is rotated by the handle 17, and the threaded rod 16 is threadedly driven with the suspension blocks 11 to adjust the position of the suspension blocks 11 while maintaining the stability of the suspension blocks 11. Furthermore, the threaded rod 16 is rotatably inserted into the fixed block 15, and the ends of the threaded rods 16 that are close to each other are fixedly connected. The threaded connection directions of the two suspension blocks 11 and the threaded rod 16 are opposite, and the threaded rods 16 are connected as a whole threaded rod. The entire rotation of the threaded rod 16 can be controlled by the handle 17 on one side, thereby controlling the suspension blocks 11 to move away and closer synchronously. In addition, the upper side of the lower end of the inclined suspension rod 5 is provided with a connecting groove 18, and the inner side of the connecting groove 18 is threaded with bolts 19. The bolts 19 all pass through the inclined suspension rod 5 and are threadedly connected to the horizontal suspension rod 10 for disassembling and replacing the horizontal suspension rod 10.
