[0002] In the power industry, the main function of the power assembly work platform is to provide a safe and stable working environment, making it convenient for workers to assemble, install, maintain and overhaul power-related equipment on the platform.

[0003] However, the existing work platform for power assembly is basically a fixed structure composed of a platform and legs. When the power accessories are placed on the platform for assembly, the height and area cannot be adjusted according to the power assembly accessories. The mismatch between the workbench size and the power assembly accessories size will cause many inconveniences and increase the difficulty of assembly work. At the same time, during assembly, it may be affected by external dust or debris generated during assembly, which reduces the accuracy and quality of power parts after assembly. The inability to position and adjust the power assembly accessories on the platform will reduce the efficiency of assembly. Therefore, in view of the inconvenience caused by the mismatch between the workbench size and the size of the power assembly parts, and the problem that the single fixed structure workbench greatly affects the efficiency of power component assembly, a power assembly work platform with a variable operating area and its use method can be designed.

[0023] A method for using a power assembly work platform with a variable operating area comprises the following steps: Step 1: The staff stands at the avoidance position of the operating table to prepare for assembly, places the power parts to be assembled on the upper end of the placement plate in the positioning assembly, starts the drive motor to control the bidirectional threaded rod to start running, and the bidirectional threaded rod drives the two threaded sleeves to move outward and backward synchronously, and the linkage hydraulic clamp also moves outward; At the same time, the electromagnet at one end of the hydraulic clamp is attracted to the metal block of the side plate, and the side plate is pushed outward, causing the sliding plate at the rear end to slide horizontally in the sliding groove, and cooperate with the upper and lower isolation membranes to expand the isolation range. The side plate also drives the expansion platform to slide horizontally, thereby realizing the expansion platform to expand to both sides. After expanding to a suitable operating space according to the size of the assembled power component, the power component is placed on the placement plate, and then the adsorption of the electromagnet and the metal block is released, and then the bidirectional threaded rod is driven in the reverse direction, so that the two hydraulic clamps move toward each other to stably clamp the power component to be assembled; The linear drive structure B at the rear end of the electric component to be assembled drives the upper clamp plate to move downward, pressing the upper part of the electric component to be assembled, further ensuring the stability of the electric component to be assembled. Since a connecting plate is installed between the upper clamp plate and the dust collector head, when the upper clamp plate moves downward, the dust collector head is driven to move downward and maintains a safe distance from the electric component to be assembled. The gap between the dust collector head and the electric component to be assembled is maintained at 50 cm, realizing the precise positioning of the dust collector port and improving the accuracy of capturing dust and debris. Step 2: During assembly, the remaining accessories can be placed on the operating table. If there are too many accessories, they can be placed on the expansion table to expand the area on both sides of the operating table to accommodate more accessories and improve the convenience of power assembly work; The processed electrical parts can also be stored in the storage cabinet at the bottom of the operating table. When the storage cabinet is full, the staff controls the cylinder group to drive the storage cabinet downward. After the pulley of the storage cabinet touches the ground, the storage cabinet is pulled out and replaced with an empty storage cabinet. This operation can maximize the use of the operating space and avoid the tedious manual handling. Step 3: When vacuuming, start the vacuum fan to absorb the dust and debris generated during the power assembly in the lower assembly space. The airflow with dust and debris enters the processing box along the first section of the vacuum pipe, passes through the filter to block the dust and debris before entering the second section of the vacuum pipe, and then is discharged. Under the action of the linear drive structure A and the guide rod, the cleaning brush moves back and forth to clean the dust and debris on the surface of the filter and drop it to the bottom of the processing box. The inspection door can be opened later to clean the dust and debris stored inside. Step 4: If the electric component needs to be turned during the assembly process, first turn off the electromagnet and release the connection between the electromagnet and the metal block. Then, turn the operating handle at the front end of the worm gear, and the worm gear will rotate in conjunction with the worm gear to adjust the placement plate at the upper end of the rotating shaft to rotate. A support foot with a ball bearing is installed at the lower end of the placement plate, and an annular groove is provided at the upper end of the operating table. When the placement plate rotates, the support foot with the ball bearing slides in the annular groove, ensuring the smoothness and stability of the rotation of the placement plate. This design allows the electric component to be assembled at the optimal angle, making the assembly process faster. The beneficial effects of the present invention are as follows: compared with the traditional single fixed structure work platform, the present invention can stably clamp the power assembly parts and perform stable and smooth steering through the clamping mechanism, and when operating the positioning component, the side plates at both ends can be linked with the expansion platform to expand in both directions, and expand to a suitable operating space according to the size of the assembled power parts. This design enables the power parts to be assembled at the best angle, making the assembly process faster. The workbench surface area can be expanded according to the assembly requirements through the expansion component to achieve the purpose of accommodating more accessories and improve the convenience of power assembly work. At the same time, the isolation membrane can be expanded synchronously with the expansion component to expand the isolation range. , reducing the impact of external dust on assembly work. During assembly work, since a connecting plate is installed between the upper clamping plate and the dust suction head, the dust suction head is driven to move downward when the upper clamping plate moves downward, and maintains a safe distance from the electrical parts to be assembled, thereby achieving precise positioning of the dust suction port and improving the accuracy of capturing dust and debris. At the same time, the dust suction component is started to absorb the dust and debris generated during the electrical assembly in the assembly space, reducing the impact of the debris generated during assembly, and greatly improving the accuracy and quality of the electrical parts after assembly. A detachable storage cabinet is installed in the free area at the lower end of the operating table, which can maximize the use of the operating space and avoid the tedious process of manual handling of electrical parts.

The upper clamping plate 18 is fixedly connected to the vacuum head 610 via a connecting plate 19.

[0035] A method for using a power assembly work platform with a variable operating area, the steps of which are as follows: Step 1: The staff stands at the avoidance position 9 of the operating table 1 to prepare for assembly, places the power parts to be assembled on the upper end of the placement plate 801 in the positioning assembly, starts the driving motor 805 to control the bidirectional threaded rod 806 to start running, and the bidirectional threaded rod 806 drives the two threaded sleeves 807 to move outward and backward synchronously, and the linkage hydraulic clamping member 808 also moves outward; At the same time, the electromagnet 12 at one end of the hydraulic clamp 808 is attracted to the metal block 13 of the side plate 702, and the side plate 702 is pushed outward, causing the sliding plate 704 at the rear end to slide horizontally in the sliding groove 703, and cooperate with the upper and lower isolation membranes to expand the isolation range. The side plate 702 also drives the expansion platform 5 to slide horizontally, thereby realizing the expansion of the expansion platform to both sides. After expanding to a suitable operating space according to the size of the assembled power component, the power component is placed on the placement plate, and then the extension shaft of the hydraulic clamp is driven to extend, so that the clamping heads located on the extended ends of the two hydraulic clamps move toward each other to stably clamp the power component to be assembled; The linear drive structure B17 at the rear end of the electric component to be assembled drives the upper clamping plate 18 to move downward, pressing the upper part of the electric component to be assembled, further ensuring the stability of the electric component to be assembled. Since a connecting plate 19 is installed between the upper clamping plate 18 and the dust collector head 610, when the upper clamping plate 18 moves downward, the dust collector head 610 is driven to move downward and maintains a safe distance from the electric component to be assembled. The gap between the dust collector head 610 and the electric component to be assembled is maintained at 50 cm, realizing the precise positioning of the dust collector port and improving the accuracy of capturing dust and debris. Step 2: During assembly, the remaining accessories can be placed on the operating table 1. If there are too many accessories, they can be placed on the expansion table 5 to expand the area on both sides of the operating table 1 to accommodate more accessories and improve the convenience of power assembly work; Moreover, the processed electrical parts can be stored in the storage cabinet 16 at the lower end of the operating table 1. When the storage cabinet 16 is full, the staff controls the cylinder group 15 to drive the storage cabinet 16 to move downward. After the pulley of the storage cabinet 16 contacts the ground, the storage cabinet 16 is pulled out and replaced with an empty storage cabinet 16. This operation can maximize the use of the operating space and avoid the tedious manual handling. Step 3: When vacuuming, start the vacuum fan 601 to absorb the dust and debris generated during the power assembly in the lower assembly space. The airflow with dust and debris enters the processing box 603 along the first section of the vacuum pipe 602, and passes through the filter 605 to block the dust and debris before entering the second section of the vacuum pipe 604, and then the airflow is discharged. Under the action of the linear drive structure A607 and the guide rod 608, the cleaning brush 606 reciprocates and moves to clean the dust and debris on the surface of the filter 605 and drops it to the bottom of the processing box 603. The inspection door 609 can be opened later to clean the dust and debris stored inside. Step 4: If the electric component needs to be turned during the assembly process, first turn off the electromagnet 12 to release the connection between the electromagnet 12 and the metal block 13, and then turn the operating handle at the front end of the worm 804. The worm 804 is linked to the worm wheel 803 on the side to rotate, so as to adjust the placement plate 801 at the upper end of the rotating shaft 802 for rotation. A bull's eye bearing is installed at the lower end of the placement plate 801. When the placement plate 801 rotates, the ball support leg slides in the annular groove, ensuring the smoothness and stability of the rotation of the placement plate 801. This design allows the electric component to be assembled at the optimal angle, making the assembly process faster.

[0036] Through the above steps, the positioning component can stably clamp the power assembly parts and make stable and smooth steering. When operating the positioning component, the side panels at both ends can be linked with the expansion table to expand in both sides, and expand to a suitable operating space according to the size of the assembled power parts. This design allows the power parts to be assembled at the best angle, making the assembly process faster. The expansion component can be used to expand the workbench surface area according to the assembly requirements to accommodate more accessories and improve the convenience of power assembly work. At the same time, the partition component can be expanded synchronously with the expansion component, which expands the isolation range and reduces the impact of external dust on the assembly work. During assembly work, since a connecting plate is installed between the upper clamping plate 18 and the dust suction head 610, when the upper clamping plate 18 moves downward, the dust suction head 610 is driven to move downward and maintains a safe distance from the electrical components to be assembled, thereby achieving precise positioning of the dust suction port and improving the accuracy of capturing dust and debris. At the same time, the dust suction component is started to absorb the dust and debris generated during the electrical assembly in the assembly space, reducing the impact of the debris generated during assembly and greatly improving the accuracy and quality of the electrical components after assembly. A detachable storage cabinet 16 is installed in the vacant area at the lower end of the operating table 1, which can maximize the use of the operating space and avoid the tedious process of manual handling of electrical components.

10. The method for using the power assembly work platform with a variable operating area according to claim 9, characterized in that: The following steps are involved: Step 1: A worker stands at the avoidance position (9) of the operating table (1) to prepare for assembly, places the electrical component to be assembled on the upper end of the placement plate (801) in the positioning assembly, starts the drive motor (805) to control the bidirectional threaded rod (806) to start running, and the bidirectional threaded rod (806) drives the two threaded sleeves (807) to move outward and backward synchronously, and the linkage hydraulic clamping member (808) also moves outward; At the same time, the electromagnet (12) at one end of the hydraulic clamp (808) is attracted to the metal block (13) of the side plate (702), and the side plate (702) is pushed outward, causing the sliding plate (704) at the rear end to slide horizontally in the sliding groove (703). Together with the upper and lower isolation membranes, the isolation range is expanded. The side plate (702) also drives the expansion platform (5) to slide horizontally, thereby achieving expansion of the expansion platform in both directions. After the expansion reaches a suitable operating space according to the size of the assembled power component, the power component is placed on the placement plate, and then the extension shaft of the hydraulic clamp is driven to extend, so that the clamping heads located at the extended ends of the two hydraulic clamps move toward each other to stably clamp the power component to be assembled; The linear drive structure B (17) at the rear end of the electric component to be assembled drives the upper clamping plate (18) to move downward, pressing the upper part of the electric component to be assembled, thereby further ensuring the stability of the electric component to be assembled. Since a connecting plate (19) is installed between the upper clamping plate (18) and the dust collector head (610), when the upper clamping plate (18) moves downward, the dust collector head (610) is driven to move downward and maintains a safe distance from the electric component to be assembled. The gap between the dust collector head (610) and the electric component to be assembled is maintained at 50 cm, thereby achieving accurate positioning of the dust collector port and improving the accuracy of capturing dust and debris. Step 2: During assembly, the remaining accessories can be placed on the operating table (1). If there are too many accessories, they can be placed on the expansion table (5) to expand the area on both sides of the operating table (1) to accommodate more accessories and improve the convenience of power assembly work; Furthermore, the processed electrical components can be stored in a storage cabinet (16) at the lower end of the operating table (1). When the storage cabinet (16) is full, the staff controls the cylinder group (15) to drive the storage cabinet (16) to move downward. After the pulley of the storage cabinet (16) contacts the ground, the storage cabinet (16) is pulled out and replaced with an empty storage cabinet (16). This operation can maximize the use of the operating space and avoid the tedious manual handling. Step 3: When vacuuming, the vacuum fan (601) is started to absorb dust and debris generated during the electrical assembly in the lower assembly space. The airflow carrying dust and debris enters the processing box (603) along the first section of the vacuum pipe (602). Before entering the second section of the vacuum pipe (604), the airflow passes through the filter (605) to block the dust and debris and is then discharged. Under the action of the linear drive structure A (607) and the guide rod (608), the cleaning brush (606) moves back and forth to clean the dust and debris on the surface of the filter (605) and drop it to the bottom of the processing box (603). The inspection door (609) can be opened later to clean the dust and debris stored inside. Step 4: If it is necessary to turn the electric component during the assembly process, first turn off the electromagnet (12) to release the connection between the electromagnet (12) and the metal block (13), then turn the operating handle at the front end of the worm (804), and the worm (804) is linked to the worm wheel (803) on the side to rotate, so as to adjust the placement plate (801) at the upper end of the rotating shaft (802) to rotate. A bull's eye bearing is installed at the lower end of the placement plate (801). When the placement plate (801) rotates, the ball support leg slides in the annular groove, ensuring the smoothness and stability of the rotation of the placement plate (801). This design allows the electric component to be assembled at the optimal angle, making the assembly process faster.
