Abstract
Description
Technical Field
[0001] This invention relates to the field of power distribution cabinet installation technology, specifically to a power distribution cabinet suspension installation device and its hoisting method. Background Technology
[0002] As a key piece of equipment in a power system, the installation of a distribution cabinet typically requires lifting the cabinet to a preset height and precisely positioning it. Traditional installation methods mainly include manual lifting and positioning or using hoisting equipment to adjust the position and then fix it in place.
[0003] Manual operation often requires multiple people to lift the distribution cabinet and position it while it is suspended in the air. Operators must carry heavy loads continuously, resulting in high physical exertion and labor intensity. Moreover, manual adjustment relies on experience, making it difficult to achieve alignment in one go. It often requires repeated lifting and lowering for correction, which is inefficient.
[0004] To address the installation challenges of similar large power equipment, Chinese Patent Publication No. CN115910532A discloses a transformer installation device and method, including two clamping members, a support plate assembly, a mounting plate, and a clamping assembly. The two clamping members are respectively installed in the middle of two utility poles; the support plate assembly is positioned above the two clamping members, with the two utility poles passing through it; the mounting plate is positioned above the support plate assembly and is used to place the transformer. The mounting plate has a first positioning groove with an upward opening, and the bottom of the transformer has a first positioning block that engages with the first positioning groove; the clamping assembly includes two clamping members slidably connected to the support plate assembly, located on the front and rear sides of the transformer, for moving towards each other to clamp the transformer. The transformer installation device provided by this invention can accurately place the transformer in a predetermined position through the engagement of the first positioning block and the first positioning groove, and quickly fix the transformer using the two clamping members, preventing the transformer from falling.
[0005] The aforementioned technology employs a lifting and then manual fine-tuning operation mode. It requires using cranes or other equipment to lift the transformer onto the support plate assembly. Then, operators simultaneously adjust multiple screw-type clamping components to precisely position and secure the equipment. After coarse positioning is completed, the operator immediately transitions to the screw fine-tuning stage without any transition. Throughout the entire installation process, the operator must maintain the equipment suspended in the air and work continuously. From lifting and positioning to screw locking, continuous operation and support of the equipment's weight are required. In a high-altitude working environment, such continuous heavy-duty work easily leads to fatigue and safety hazards. Summary of the Invention
[0006] The purpose of this invention is to provide a suspended installation device for power distribution cabinets and its hoisting method in order to solve the above-mentioned problems. By first fixing the support plate as a foundation, then using the self-weight of the power distribution cabinet to drive the automatic locking device, and finally fine-tuning the calibration components in a step-by-step operation, the traditional installation mode of having to manually lift and position the cabinet throughout the process can be avoided. The self-weight is converted into locking power, reducing the operator's continuous load and saving physical exertion. See the following description for details.
[0007] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a suspended installation device for a power distribution cabinet, comprising a support plate, a mounting plate, and a power distribution cabinet body. A connecting plate for adjusting the position of the mounting plate is provided between the support plate and the mounting plate. The power distribution cabinet body is disposed on one side of the mounting plate. The device also includes a support plate, a locking component, and a calibration component.

A support plate is provided on one side of the connecting plate. Locking posts are vertically slidably disposed at both ends of the support plate. The I-beam plate and the locking posts can be separated and pressed together. A compression spring for supporting the I-beam plate is sleeved on the outside of the locking posts. A connecting component for fixing the I-beam plate is provided between the I-beam plate and the support plate. The locking assembly includes multiple locking ports vertically distributed in the middle of the locking posts. A fixing plate is installed in the middle of each locking port. Sliding posts are fixed on both sides of the fixing plate. A locking block is provided at the end of each sliding post, which can slide out of the locking port and abut against the bottom side of the support plate. A locking spring for driving the locking block to extend is sleeved in the middle section of the sliding post. The calibration assembly includes multiple sleeves disposed on one side of the mounting plate. A calibration post is slidably disposed in the middle of each sleeve. A calibration rod is disposed at the outer end of each calibration post. Multiple calibration ports are opened in the middle of the connecting plate to fit and lock with the calibration rod. The calibration ports are used to calibrate the position of the mounting plate and the connecting plate in cooperation with the calibration rod.
[0008] Preferably, the upper side of the support plate is provided with a plurality of limiting posts, and an adjustment plate is provided between the plurality of limiting posts. A limiting block for limiting the height of the adjustment plate is provided in the middle section of the limiting posts.
[0009] Preferably, the top of the adjustment plate is provided with a plurality of protective cylinders corresponding one-to-one with the locking posts. The top of the protective cylinder is higher than the uppermost locking block. The protective cylinder is used to limit the pop-out range of the locking block. The inner diameter of the compression spring is larger than the outer diameter of the protective cylinder. The protective cylinder can prevent the pop-out of the locking block from affecting the operation of the compression spring.
[0010] Preferably, the bottom of the adjustment plate is provided with a plurality of locking rings corresponding to the locking post. The diameter of the locking ring is larger than the diameter of the locking post. The bottom of the locking ring is provided with a limiting plate. The radius of the limiting plate is larger than the distance from the end of the locking block to the axis of the locking post. The limiting plate is used to increase the limiting area on the upper side of the locking block.
[0011] Preferably, the connecting assembly includes a connecting frame disposed outside the support plate, connecting columns slidably disposed on both sides of the connecting frame, and top plates disposed at opposite ends of the two connecting columns. Each connecting column located between the top plate and the connecting frame is fitted with a top support spring for driving the displacement of the top plate. Top blocks are disposed on opposite sides of the two sets of top plates. The top of the top block is an inclined surface, and the inclined surfaces of two adjacent top blocks form a V-shaped groove. A connecting block is disposed at the bottom of the I-beam plate, and a wedge block for separating the two top blocks is disposed at the bottom of the connecting block. Both sides of the wedge block are provided with a baffle plate for preventing the wedge block from rising through the gap between the top block and the wedge block.
[0012] Preferably, the top of the locking post is provided with a pad for supporting the I-beam plate, the connecting frame is provided on one side of the pad, the pad is slidably connected to the T-shaped hole, the two sides of the pad are provided with clamps to enhance the sliding stability of the pad, the two sides of the I-beam plate are provided with multiple extension blocks, the extension blocks are fitted with the connecting plate to enhance the stability of the I-beam plate during sliding, and the bottom of the T-shaped hole is fixedly connected with a guide post, the middle part of the guide post is slidably connected to the adjacent pad and the I-beam plate respectively, the guide post is used to improve the docking stability of the I-beam plate and the pad.
[0013] Preferably, the calibration assembly further includes a pre-tightening spring disposed in the middle section of the calibration column. A calibration plate is disposed at one end of the calibration column. The two ends of the pre-tightening spring abut against the ends of the calibration plate and the sleeve, respectively. The pre-tightening spring is used to drive the calibration column to rebound so that the calibration rod fits tightly against the side of the connecting plate. A positioning groove with the same shape as the calibration rod is opened on one side of the calibration port. After the calibration assembly is calibrated, the calibration rod can be rotated into the positioning groove by the calibration column to make the position of the calibration rod more stable.
[0014] Preferably, the distribution cabinet body has multiple adjustment ports on one side corresponding to the calibration plate, and the distribution cabinet body, the connecting plate, and the mounting plate each have a corresponding connection port in the middle, which is used to fix the relative position between the distribution cabinet body, the connecting plate, and the mounting plate.
[0015] Preferably, a bracket is provided between the support plate and the connecting plate to increase the distance between the connecting plate and the mounting surface, and the bottom of the connecting plate is provided with multiple heat dissipation holes for heat dissipation of the power distribution cabinet body.
[0016] The present invention also provides a method for hoisting the suspended installation device of the distribution cabinet, comprising the following steps: a. Pre-installation process: When installing the distribution cabinet, fix the support plate on the mounting surface, then move the mounting plate to a position roughly flush with the connecting plate. Move the mounting plate so that the I-beam plate on one side of the mounting plate is inserted through the wider end of the T-shaped hole. Then move it up and down so that the middle part of the I-beam plate enters the narrower part of the T-shaped hole. At this time, the I-beam plate slides up and down with the connecting plate through the T-shaped hole. The mounting plate completes the initial installation with the connecting plate and the bracket through the T-shaped hole. b. Position Locking Process: Release the mounting plate, allowing it to slide down under its own weight. This causes the I-beam to move to the top of the locking post. The locking post, under pressure, slides down along the support plate. During this process, as the I-beam and locking post move downwards, the compression spring is compressed, absorbing the impact of the downward movement of the mounting plate and I-beam, preventing damage to the distribution cabinet body due to excessive impact. Simultaneously, the locking post drives the locking assembly to move synchronously. During this downward movement, the locking block contacts the support plate and, under the impact of the downward movement of the distribution cabinet body and mounting plate, retracts along the sliding post into the locking slot. At the same time, the locking spring is compressed by the locking block to store energy. Until the locking block is moved to the bottom of the support plate by the locking pin, the outer limit of the locking port is lost. One end of the locking spring abuts against the fixed plate and the other end pushes the locking block to move outward until the mounting plate stops moving down. At this time, the mounting plate is positioned and the position of the distribution cabinet body is also stable. The I-beam plate and the support plate are connected by the connecting component. When the mounting plate wants to move up significantly, the locking block closest to the support plate will contact the bottom of the support plate and lock the position of the mounting plate. Thus, the position of the mounting plate is initially fixed within a controllable range, without the need for manual continuous height lifting of the mounting plate for installation. c. Position Calibration Process: By lifting the distribution cabinet body and the mounting plate and moving them up and down along the T-shaped hole, the calibration column can move the calibration rod up and down to the adjacent calibration port. Since there is a certain distance between the locking block and the support plate, the distribution cabinet body can move upward. Since the compression spring can be compressed, the distribution cabinet body moves downward to further compress the compression spring. Through the position locking process, the position of the mounting plate has been initially fixed. Then, move the position of the mounting plate and the distribution cabinet body until the distribution cabinet body and the mounting plate drive the calibration column to align with the calibration port. At this time, push the calibration column to drive the calibration rod into the calibration port. At this time, the operator is no longer under force, and the weight of the distribution cabinet body is supported by the calibration column. Rotate the calibration column to rotate the calibration rod. At this time, the calibration rod is no longer aligned with the calibration port and cannot be directly separated from the calibration port. The position calibration and alignment between the mounting plate and the connecting plate is completed, and the position of the mounting plate is fixed by the calibration column to prevent it from shaking.
[0017] The beneficial effects are as follows: 1. The present invention uses a step-by-step operation of first fixing the support plate as the foundation, then using the self-weight of the power distribution cabinet to drive the automatic locking device, and finally fine-tuning the calibration components. This avoids the traditional operation mode of having to manually lift and position the entire process during installation, and converts the self-weight into locking power, reducing the operator's continuous load and saving physical exertion. 2. After the device is locked, it is finely adjusted through an independent calibration component, which can accurately eliminate the slight positional deviation of the mounting plate. The cooperation between the calibration rod and the positioning groove and the continuous pre-tension of the pre-tensioning spring ensure that the calibrated position is continuously locked, effectively reducing the probability of positional displacement caused by vibration or external force during equipment operation, and ensuring the long-term accuracy and reliability of the power distribution cabinet installation. 3. The guide column, together with the extension block and clamping plate, provides multiple guidance, which can reduce positional deviation during the assembly process, reduce the skill requirements of the operators, and improve installation efficiency; 4. It saves a lot of time on manual support and repeated alignment. The step-by-step operation process is clear and simple, which shortens the installation time of a single distribution cabinet. In batch installation or large-scale projects, it can effectively shorten the overall construction cycle and reduce the overall installation cost. 5. The bracket works in conjunction with the bottom heat dissipation holes, which solves the heat dissipation problem when installing in a small space, and also forms a natural convection airflow channel, thus optimizing the compact structure and heat dissipation efficiency.

Detailed Implementation
[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.
[0022] See Figures 1-11As shown, the present invention provides a suspended installation device for a power distribution cabinet, including a support plate 1, a mounting plate 3, and a power distribution cabinet body 9. A connecting plate 2 for adjusting the position of the mounting plate 3 is provided between the support plate 1 and the mounting plate 3. The power distribution cabinet body 9 is disposed on one side of the mounting plate 3. The device also includes a support plate 5, a locking component 6, and a calibration component 8. A plurality of T-shaped holes 201 are formed in the middle of the connecting plate 2. An I-beam 4 for connecting the T-shaped holes 201 is fixed on one side of the mounting plate 3. The size of the I-beam 4 is smaller than the top width of the T-shaped holes 201 to allow them to be inserted from the top. The plate 4 is inserted and slid into the narrow part. The thickness of the I-beam plate 4 is equal to the thickness of the connecting plate 2. The width of the middle plate of the I-beam plate 4 is equal to the width of the narrow part of the T-shaped hole 201. This achieves a stable sliding connection between the mounting plate 3 and the connecting plate 2. A support plate 5 is provided on one side of the connecting plate 2. Locking pins 503 are vertically slidably provided at both ends of the support plate 5. The I-beam plate 4 and the locking pins 503 can be separated and pressed together. A compression spring 505 for supporting the I-beam plate 4 is sleeved on the outside of the locking pins 503. A connecting component 7 for fixing the I-beam plate 4 is provided between the I-beam plate 4 and the support plate 5. The locking assembly 6 includes multiple vertically distributed locking openings 601 located in the middle of the locking post 503. A fixing plate 602 is installed in the middle of the locking opening 601. Sliding posts 603 are fixed on both sides of the fixing plate 602. A locking block 604 is provided at the end of the sliding post 603, which can slide out of the locking opening 601 and abut against the bottom side of the support plate 5. A locking spring 605 is sleeved in the middle section of the sliding post 603 to drive the locking block 604 to extend. The locking block 604 can retract and lock when it is squeezed by the support plate 5 during the downward movement of the locking post 503. The mounting plate 3 is moved upward by a locking spring 605 after it moves down to the bottom of the support plate 5, thus limiting the large upward movement of the mounting plate 3. The calibration assembly 8 includes multiple sleeves 802 disposed on one side of the mounting plate 3. A calibration post 801 is slidably disposed in the middle of the sleeve 802. A calibration rod 804 is disposed at the outer end of the calibration post 801. Multiple calibration ports 805 are opened in the middle of the connecting plate 2 to fit and lock with the calibration rod 804. The calibration ports 805 are used to cooperate with the calibration rod 804 to calibrate the position of the mounting plate 3 and the connecting plate 2.
[0023] See Figures 4-8As shown, in an optional implementation, the upper side of the support plate 5 is provided with multiple limiting posts 501, and an adjusting plate 502 is provided between the multiple limiting posts 501. A limiting block 501a for limiting the height of the adjusting plate 502 is provided in the middle section of the limiting posts 501. Multiple protective cylinders 608 corresponding one-to-one with the locking posts 503 are provided on the top of the adjusting plate 502. The top of the protective cylinder 608 is higher than the uppermost locking block 604. The protective cylinder 608 is used to limit the pop-out range of the locking block 604. The inner diameter of the compression spring 505 is larger than the outer diameter of the protective cylinder 608. Adjacent... The compression spring 505, the protective cylinder 608, and the locking post 503 are aligned. The protective cylinder 608 can prevent the locking block 604 from popping out and affecting the operation of the compression spring 505. The bottom of the adjusting plate 502 is provided with multiple locking rings 606 corresponding to the locking post 503. The diameter of the locking ring 606 is larger than the diameter of the locking post 503. The bottom of the locking ring 606 is provided with a limiting plate 607. The radius of the limiting plate 607 is larger than the distance from the end of the locking block 604 to the axis of the locking post 503. The limiting plate 607 is used to increase the limiting area on the upper side of the locking block 604. With this configuration, when the mounting plate 3 is moved downwards for installation, it can be better limited by the cooperation of the adjusting plate 502 and the locking component 6. Specifically, when the locking post 503 moves the locking component 6 downwards, it first passes through the adjusting plate 502. After the locking component 6 passes through the adjusting plate 502, the locking block 604 will lose its limit and immediately extend. At this time, it will no longer be limited by the support plate 5. When it is necessary to move the mounting plate 3 upwards significantly, the I-beam 4 will move the locking post 503 upwards. The locking post 503 will move the adjusting plate 502 upwards along the guide of the limiting post 501 through the locking component 6. At the same time, the compression spring 505 will also release its stored pressure during this process, assisting the operator and reducing the difficulty of upward movement. Before the locking pin 503 moves, all locking components 6 are confined within the locking opening 601 by the protective cylinder 608. Specifically, all locking blocks 604 are in contact with the inner wall of the protective cylinder 608 and cannot move out of the locking opening 601. This prevents the compression spring 505 from being interfered with by the extended locking blocks 604 and getting stuck when it extends and retracts. When the locking pin 503 moves up and down, some locking components 6 move down out of the range of the protective cylinder 608 and enter the locking ring 606 through the adjusting plate 502 to continue to be limited by the locking ring 606 until they move out of the bottom of the locking ring 606. The locking blocks 604 extend out of the locking opening 601. At this time, the top of the locking component 6 is the limiting plate 607. The longer diameter of the limiting plate 607 can generate a larger contact area with the extended locking blocks 604 when they move up, resulting in a better limiting effect and preventing the locking blocks 604 from retracting when they move up, which would cause the locking to fail. When the mounting plate 3 is installed, the adjusting plate 502 will move downwards because it is a sliding connection. The limiting block 501a in the middle of the limiting plate 607 can effectively prevent the adjusting plate 502 from moving downwards too much. By controlling the position of the limiting plate 607, the position of the adjusting plate 502 and the final mounting plate 3 moving downwards along the T-hole 201 can be controlled. When the position of the limiting block 501a is too high, the final position where the mounting plate 3 stops moving downwards will naturally be too high. By adjusting and optimizing the position of the limiting block 501a, the positional deviation between the mounting plate 3 and the connecting plate 2 when the mounting plate 3 stops moving downwards can be reduced. See Figures 9-10 As shown, the connecting assembly 7 includes a connecting frame 701 disposed outside the support plate 5. Connecting columns 702 are slidably disposed on both sides of the connecting frame 701. Top plates 703 are disposed at opposite ends of the two connecting columns 702. The column of the connecting column 702 located between the top plate 703 and the connecting frame 701 is fitted with a top support spring 704 for driving the displacement of the top plate 703. Top blocks 705 are disposed on opposite sides of the two sets of top plates 703. The top of the top block 705 is an inclined surface. The inclined surfaces of two adjacent top blocks 705 form a V-shaped groove. The bottom of the two top blocks 705 is a flat surface. A connecting block 706 is disposed at the bottom of the I-beam plate 4. A wedge block 707 for separating the two top blocks 705 is disposed at the bottom of the connecting block 706. A baffle plate 707a is disposed on both sides of the wedge block 707 to prevent the wedge block 707 from rising through the gap between the top block 705 and the wedge block 707. With this configuration, when the mounting plate 3 carrying the distribution cabinet body 9 falls along the T-shaped hole 201, its own weight is transmitted to the connecting block 706 and the wedge block 707 through the I-beam plate 4, driving the wedge block 707 to fall and insert into the V-shaped groove formed by the two top blocks 705 inside the connecting frame 701. During the falling process of the wedge block 707, its wedge-shaped surface continuously presses against the inclined surfaces of the two top blocks 705, overcoming the elastic force of the top support spring 704, forcing the two top blocks 705 to slide outward along the connecting column 702 and compress the top support spring 704. When the wedge block 707 has completely fallen to the bottom of the connecting frame 701, the connecting block 706 at its top is exactly located between the two top blocks 705. At this time, the top support spring 704 releases the stored elastic force, driving the two top blocks 705 to quickly spring back to their original position. During the reset process, the inner planes of the two top blocks 705 are tightly fitted to the two sides of the connecting block 706 on the top of the wedge block 707, forming a stable clamping force. At the same time, the bottom planes of the two top blocks 705 and the structure of the top of the wedge block 707 being wider than the bottom form a barrier, which can be tightly fitted to the bottom of the top blocks 705 to prevent rebound. Meanwhile, the retaining plate 707a on the top of the wedge block 707 is larger than the top of the wedge block 707, and the small gap between the two top blocks 705 cannot allow the retaining plate 707a to pass through. In this way, it can more effectively prevent the top blocks 705 and the wedge blocks 707 from accidentally separating, ensuring that the connecting block 706 is stably clamped, thereby achieving a fast and stable locking between the mounting plate 3 and the support plate 5 without the need for additional manual operation. See Figures 4-9 As shown, the top of the locking post 503 is provided with a pad 504 for supporting the I-beam plate 4. The connecting frame 701 is provided on one side of the pad 504. The pad 504 is slidably connected to the T-shaped hole 201. The two sides of the pad 504 are provided with clamping plates 504a to enhance the sliding stability of the pad 504. Both sides of the I-beam plate 4 are provided with multiple extension blocks 401. The extension blocks 401 are attached to the connecting plate 2 to enhance the stability of the I-beam plate 4 when sliding. The bottom of the T-shaped hole 201 is fixedly connected with a guide post 202. The middle part of the guide post 202 is slidably connected to the adjacent pad 504 and the I-beam plate 4 respectively. The guide post 202 is used to improve the docking stability of the I-beam plate 4 and the pad 504. With this configuration, when the I-beam 4 falls along the T-shaped hole 201, its bottom first rests on the pad 504 on top of the locking post 503. The pad 504 evenly transmits the gravity to the locking post 503 and the support plate 5, avoiding excessive local pressure. At the same time, the clamping plates 504a on both sides of the pad 504 are tightly fitted to the sidewalls of the T-shaped hole 201, effectively suppressing the shaking of the I-beam 4 and the pad itself during the sliding process. The extension blocks 401 on both sides of the I-beam 4 continue to fit against the surface of the connecting plate 2, further expanding the contact area and creating more support connection area, significantly improving the positional accuracy during the sliding process and avoiding deviation. The guide post 202 at the bottom of the T-shaped hole 201 passes through the pad 504 and the I-beam 4, providing precise vertical guidance for the I-beam 4. Through its sliding connection with the pad 504, it ensures that the pad 504 and the I-beam 4 remain axially aligned during the descent, reducing the risk of misalignment caused by assembly gaps. The pad 504, clamping plate 504a, extension block 401 and guide post 202 work together to stabilize the device, achieving highly stable sliding of the I-beam 4 within the T-shaped hole 201, providing a stable guiding foundation for the subsequent docking and locking of the locking component 6 and the adjustment operation of the calibration component 8. See Figures 1-7 As shown, the calibration assembly 8 also includes a pre-tightening spring 803 set in the middle section of the calibration column 801. A calibration plate 807 is set at one end of the calibration column 801. The two ends of the pre-tightening spring 803 abut against the ends of the calibration plate 807 and the sleeve 802, respectively. The pre-tightening spring 803 is used to drive the calibration column 801 to rebound so that the calibration rod 804 fits tightly against the side of the connecting plate 2. A positioning groove 806 with the same shape as the calibration rod 804 is opened on one side of the calibration port 805. After the calibration assembly 8 is calibrated, the calibration rod 804 can be rotated into the positioning groove 806 by the calibration column 801 so that the position of the calibration rod 804 is more stable. A plurality of adjustment ports 10 corresponding to the calibration plate 807 are opened on one side of the power distribution cabinet body 9. A corresponding connection port 11 is opened in the middle of the power distribution cabinet, the connecting plate 2 and the mounting plate 3. The connection port 11 is used to fix the relative position between the power distribution cabinet body 9, the connecting plate 2 and the mounting plate 3. With this setup, when the calibration component 8 makes a fine adjustment to the position of the mounting plate 3, the operator can access the calibration plate 807 through the adjustment port 10 on the side wall of the distribution cabinet and manually push the calibration column 801 to move, so that the calibration rod 804 is precisely inserted into the corresponding calibration port 805, further shortening the distance between the calibration plate 807 and the sleeve 802. Then, the calibration column 801 is rotated, and the calibration rod 804 follows suit and is screwed into the positioning groove 806 on the side wall of the calibration port 805. The two have the same contour and mesh. At this time, the preload spring 803 is further compressed and stored, continuously applying pressure to the calibration plate 807, so that the calibration plate 807 drives the calibration column 801 to move away from the positioning groove 806, so that the calibration rod 804 fits more tightly in the positioning groove 806, enhancing the stability of the calibration rod 804. After calibration, fasteners such as bolts are used to connect the three parts of the distribution cabinet, connecting plate 2 and mounting plate 3 through the connection port 11 in the middle to lock the final installation position and ensure that the distribution cabinet does not shift position during long-term operation. See Figures 1-5 As shown, a bracket 101 is provided between the support plate 1 and the connecting plate 2 to increase the distance between the connecting plate 2 and the mounting surface. The bottom of the connecting plate 2 is provided with multiple heat dissipation holes 203 for heat dissipation of the power distribution cabinet body 9. With this configuration, when the support plate 1 is fixedly connected to the connecting plate 2 through the bracket 101, the bracket 101 can significantly increase the vertical distance between the connecting plate 2 and the mounting surface, providing sufficient space for wiring, maintenance operations and air circulation and heat dissipation at the back of the power distribution cabinet, effectively solving the operational obstacles in narrow installation environments. In addition, the heat dissipation holes 203 can accelerate the air circulation at the rear of the power distribution cabinet and enhance heat dissipation. The present invention also provides a method for hoisting a suspended installation device for a power distribution cabinet, comprising the following steps: a. Pre-installation process: When installing the distribution cabinet, fix the support plate 1 on the mounting surface, then move the mounting plate 3 to a position roughly flush with the connecting plate 2. Move the mounting plate 3 and insert the I-beam plate 4 on one side of the mounting plate 3 through the wider end of the T-shaped hole 201. Then move it up and down so that the middle part of the I-beam plate 4 enters the narrower part of the T-shaped hole 201. At this time, the I-beam plate 4 slides up and down with the connecting plate 2 through the T-shaped hole 201. The mounting plate 3 completes the preliminary installation with the connecting plate 2 and the bracket 101 through the T-shaped hole 201. b. Position Locking Process: Release the mounting plate 3, allowing it to slide down under its own weight, eventually causing the I-beam 4 to move to the top of the locking post 503. The locking post 503, under pressure, slides down along the support plate 5. During this process, as the I-beam 4 and locking post 503 move down, the compression spring 505 is compressed and absorbs the impact force of the downward movement of the mounting plate 3 and I-beam 4, preventing excessive impact force from damaging the distribution cabinet body 9. Simultaneously, the locking post 503 drives the locking assembly 6 to move synchronously. During the downward movement, the locking block 604 contacts the support plate 5 and, under the impact force of the downward movement of the distribution cabinet body 9 and mounting plate 3, retracts along the sliding post 603 into the locking port 601. At the same time, the locking spring 605 is compressed by the locking block 604. The energy is stored until the locking block 604 is moved to the bottom of the support plate 5 by the locking post 503. At this time, the external limit of the locking port 601 is lost. One end of the locking spring 605 abuts against the fixed plate 602 and the other end pushes the locking block 604 to move outward until the mounting plate 3 stops moving down. At this time, the mounting plate 3 is positioned and the position of the power distribution cabinet body 9 is also stabilized. The I-beam plate 4 and the support plate 5 are connected by the connecting component 7. When the mounting plate 3 wants to move up significantly, the locking block 604 closest to the support plate 5 will contact the bottom of the support plate 5 and lock the position of the mounting plate 3. Thus, the position of the mounting plate 3 is initially fixed within a controllable range, so that the mounting plate 3 does not need to be manually raised continuously to install it. c. Position Calibration Process: By lifting the distribution cabinet body 9 and the mounting plate 3 and moving them up and down along the T-shaped hole 201, the calibration column 801 can drive the calibration rod 804 to move up and down to the adjacent calibration port 805. Since there is a certain distance between the locking block 604 and the support plate 5, the distribution cabinet body 9 can move upward. Since the compression spring 505 can be compressed, the distribution cabinet body 9 moves downward to further compress the compression spring 505. Through the position locking process, the position of the mounting plate 3 has been initially fixed. Then, the positions of the mounting plate 3 and the distribution cabinet body 9 are moved until the position is fixed. The cabinet body 9 and the mounting plate 3 drive the calibration column 801 to align with the calibration port 805. At this time, push the calibration column 801 to drive the calibration rod 804 into the calibration port 805. At this time, the operator is no longer under force, and the weight of the cabinet body 9 is supported by the calibration column 801. Rotate the calibration column 801 to rotate the calibration rod 804. At this time, the calibration rod 804 is no longer aligned with the calibration port 805 and cannot be directly separated from the calibration port 805. The position calibration and alignment between the mounting plate 3 and the connecting plate 2 are completed, and the position of the mounting plate 3 is fixed by the calibration column 801 to prevent it from shaking.
[0024] By first fixing the support plate 1 as the foundation, then using the self-weight of the distribution cabinet to drive the automatic locking device, and finally fine-tuning through the calibration component 8, the step-by-step operation avoids the traditional installation mode that requires manual lifting and positioning throughout the process. It converts the self-weight into locking power, reduces the operator's continuous load, and saves physical exertion.
[0025] After locking, the device is finely adjusted by an independent calibration component 8, which can accurately eliminate the slight positional deviation of the mounting plate 3. The cooperation between the calibration rod 804 and the positioning groove 806 and the continuous pre-tension of the pre-tensioning spring 803 ensure that the calibrated position is continuously locked, effectively reducing the probability of positional deviation caused by vibration or external force during equipment operation, and ensuring the long-term accuracy and reliability of the power distribution cabinet installation.
[0026] The guide post 202, together with the extension block 401 and the clamping plate 504a, provides multiple guidance, which can reduce positional deviation during the assembly process, reduce the skill requirements of the operators, and improve installation efficiency.
[0027] It eliminates a significant amount of time spent on manual assistance and repeated alignment. The step-by-step operation process is clear and simple, shortening the installation time of a single distribution cabinet. In batch installations or large-scale projects, it can effectively shorten the overall construction cycle and reduce the overall installation cost.
[0028] The bracket 101 works in conjunction with the bottom heat dissipation hole 203 to solve the heat dissipation problem of installation in a narrow space, and also forms a natural convection airflow channel, thus optimizing the compact structure and heat dissipation efficiency.
[0029] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.

Pre-installation process: When installing the distribution cabinet, fix the support plate (1) on the mounting surface, then move the mounting plate (3) to a position flush with the connecting plate (2), move the mounting plate (3) to insert the I-beam plate (4) on one side of the mounting plate (3) through the wider end of the T-shaped hole (201), and then move it up and down so that the middle part of the I-beam plate (4) enters the narrower part of the T-shaped hole (201). At this time, the I-beam plate (4) slides up and down with the connecting plate (2) through the T-shaped hole (201). The mounting plate (3) completes the preliminary installation with the connecting plate (2) and the bracket (101) through the T-shaped hole (201). b. Position locking process: Loosen the mounting plate (3) so that the mounting plate (3) slides down under its own weight, and finally the I-beam (4) moves down to the top of the locking post (503). The locking post (503) is pressed down and slides along the support plate (5). During this process, as the I-beam (4) and the locking post (503) move down, the compression spring (505) is pressed down and absorbs the impact force of the mounting plate (3) and the I-beam (4) moving down. At the same time, the locking post (503) will drive the locking assembly (6) to move synchronously. During the downward movement, the locking block (604) will contact the support plate (5) and retract along the sliding post (603) into the locking port (601) under the impact force of the downward movement of the distribution cabinet body (9) and the mounting plate (3). At the same time, the locking spring (605) is compressed and stored by the locking block (604). The locking block (604) is moved to the bottom of the support plate (5) by the locking post (503). At this time, the external limit of the locking port (601) is lost. One end of the locking spring (605) abuts against the fixed plate (602) and the other end pushes the locking block (604) to move outward until the mounting plate (3) stops moving down. At this time, the mounting plate (3) and the power distribution cabinet body (9) are positioned. The I-beam plate (4) and the support plate (5) are connected by the connecting component (7). When the mounting plate (3) wants to move up significantly, the locking block (604) closest to the support plate (5) will contact the bottom of the support plate (5) and lock the position of the mounting plate (3). Thus, the position of the mounting plate (3) is initially fixed within a controllable range, without the need for manual continuous height lifting of the mounting plate (3) for installation. c. Position calibration process: By lifting the distribution cabinet body (9) and the mounting plate (3) and moving them up and down along the T-shaped hole (201), the calibration column (801) can drive the calibration rod (804) to move up and down to the adjacent calibration port (805). Since there is a certain distance between the locking block (604) and the support plate (5), the distribution cabinet body (9) can move up. Since the compression spring (505) can be compressed, the distribution cabinet body (9) moves down to further compress the compression spring (505). Through the position locking process, the position of the mounting plate (3) has been initially fixed. Then, the position of the mounting plate (3) and the distribution cabinet body (9) is moved until the distribution cabinet body... (9) and the mounting plate (3) drive the calibration column (801) to align with the calibration port (805). At this time, push the calibration column (801) to drive the calibration rod (804) into the calibration port (805). At this time, the operator is no longer under force. The weight of the power distribution cabinet body (9) is borne by the calibration column (801). Rotate the calibration column (801) to make the calibration rod (804) rotate. At this time, the calibration rod (804) is no longer aligned with the calibration port (805) and cannot be directly separated from the calibration port (805). The position calibration and alignment between the mounting plate (3) and the connecting plate (2) is completed. The position of the mounting plate (3) is fixed by the calibration column (801) to prevent it from shaking.
